Clinical liability arises when a medical practitioner fails to meet the standard of reasonable medical care.1 Most medical malpractice litigation is pursued under the tort of negligence (civil cases). The burden of proof is ‘on the balance of probabilities’ in civil cases. In criminal cases, the burden of proof is ‘beyond reasonable doubt’, and the prosecution bears the burden of proof. Convictions for criminal charges such as gross negligence manslaughter (GNM) require a higher degree of wrongfulness.
 
A recent book chapter highlighted the tension and fears among healthcare professionals with rising the increasing number of high-profile GNM cases, coupled with the perception of arbitrary and inconsistent approaches to GNM investigation and prosecution in the United Kingdom2 resulting in a rapid policy review on GNM in healthcare.3 The review panel emphasised that healthcare professionals could not be, or appear to be, above the law. However, the complexities of modern healthcare and the stressful clinical environment must be taken into consideration when deciding whether to pursue a GNM investigation.
 
In 2018, Leung4 reviewed key medical manslaughter cases from the previous decade: Sellu,5 Bawa-Gaba,6 and DR Group.7 In Sellu,5 the surgeon was held in high regard by his peers and patients, and the penalty was considered unjustifiable and disproportionate. In Bawa-Gaba,6 there was criticism for failing to give due consideration to system factors.8 In DR Group,7 a retrial of one of the defendants, Dr Mak, was ongoing at the time of the 2018 review. The findings of two reviews (by the United Kingdom Government3 and the General Medical Council9) led to a perception among healthcare professionals that the legal tests for GNM were inconsistently applied.2 Thus, there is a need to review the judgements in the retrial of Dr Mak10 and another case involving a doctor convicted of GNM, Dr Kwan,11 in the context of some key historical cases and published literature.
 
Before the retrial of Dr Mak, the defendant doctor appealed on the question of requirement of the prosecution to prove the culpability of the defendant’s state of mind that she was subjectively aware of the obvious and serious risk of death to the deceased.12 The Court of Final Appeal unanimously dismissed the appeal that only application of the objective standard of reasonableness, as referred in the last element of the offence in R v Adomako,13 is needed with no additional requirement to prove the defendant’s subjective aware of an obvious and serious risk of death.12
 
In Adomako,13 an anaesthetist in charge of a patient during eye surgery failed to notice or respond to obvious signs of oxygen tube disconnection, and the patient died. The jury convicted the anaesthetist of GNM. The evidence13 indicated that 4.5 minutes would have elapsed between the disconnection and sounding of the alarm; the anaesthetist responded in various ways but did not check the oxygen tube connection. One expert witness stated that a competent anaesthetist should have recognised the disconnection within 15 seconds because the patient’s blood pressure and pulse had decreased, and the patient’s chest was not moving. Another expert witness described the standard of care as ‘abysmal’ (extremely bad). The anaesthetist’s conviction of GNM was upheld by the House of Lords on appeal.13 Lord Mackay LC set the following tests for a conviction of GNM13:
  • Had the defendant breached the duty of care towards the victim who had died?
  • If yes, whether the breach of duty had caused death?
  • If so, the jury needed to go on to consider whether that breach of duty should be characterised as gross negligence and therefore as a crime.
  • The jury would then have to consider the extent to which the defendant’s conduct departed from the proper standard of care constituting a risk of death to the patient, was such that it should be judged criminal.
  • The jury question was whether the conduct of the defendant was so bad in all the circumstances as to amount in their judgement to a criminal act.
  •  
    There was an argument about circularity because the jury was asked to define whether an offence had been committed; the jury’s task is to determine the facts, then apply the law. Lord Mackay was aware of the element of circularity and he did not believe that it would be fatal as the test being correct to determine how far the conduct should depart from the accepted standard to be characterised as criminal. The judgement of the Court of Final Appeal regarding Dr Mak stated that the test is not circular and there is no abdication of the judge’s role in defining the offence for the jury.12 Juries are assisted by expert evidence when considering difficult questions, and it is not unusual for juries to perform an evaluative function.12 In R v Misra,14 Judge LJ pointed out that the jury would be asked difficult questions, such as whether a defendant had acted dishonestly by reference to the contemporary standard, or when charged on dangerous driving causing death, whether the standard of driving fell far below the standard to be expected as a competent driver.15
     
    In Misra,15 the doctor was convicted of GNM when their patient became infected with Staphylococcus aureus after surgery and did not receive the necessary treatment. The defendant doctor appealed on the basis that the test for gross negligence presented to the jury was circular and unclear. The appeal was dismissed; the jury’s determination of ‘gross negligence’ was regarded as a question of fact, rather than a question of law. The Lord Justice Judge wrote that there was a failure to appreciate the patient’s serious illness, including the classic signs of infection (elevated temperature, rapid pulse, and lowered blood pressure). The mistakes made were elementary.16
     
    In the retrial of Dr Mak,10 the defendant doctor was found guilty of GNM by the jury. The judge was satisfied that the jury must have found the defendant doctor in breach of her duty to the deceased and it was reasonably foreseeable that the breach of that duty giving rise to a serious and obvious risk of death and indeed caused the death. The jury must have also been satisfied that the circumstances of the breach were truly exceptionally bad and so reprehensible to justify criminal punishment.
     
    In Dr Kwan,13 the patient attended for liposuction procedure. The patient was infused with the combination of sedative drugs at the start of the procedure and she was deeply sedated and unconscious. She was attached to the Mindray machine during the procedure and the device alarmed throughout the procedure indicating that there was a problem with patient’s vital signs. The alarm was ignored and silenced each time by one of the assistants. After the completion of the procedure, the defendant doctor left leaving the patients under the care of medically untrained assistants while the patient was still unconscious. The defendant doctor was called back by her assistants when the patient’s condition had deteriorated. The defendant doctor called for help but did not provide resuscitation of basic life support.
     
    The jury’s verdict was that the defendant’s failures fell far below the standard of a competent doctor.13 The inactions and actions of the defendant substantially caused the death of the patient. A reasonably competent doctor would have foreseen that the breach of her duties gave rise to a serious and obvious risk of death and her breach was so truly exceptionally bad and so reprehensible.
     
    In R v Rose,17 the defendant optometrist negligently failed to examine the retinas of a child and thus did not identify papilledema; consequently, hydrocephalus in the child was not diagnosed or treated, and the child died a few months later. The Court of Appeal held that, in failing to examine the eye at all, the optometrist would not have been aware of ‘a serious and obvious risk of death’; thus, Rose was considered simply negligent. Conversely, in R v Winterton,18 the defendant construction manager was convicted of manslaughter when a trench collapsed on a labourer, causing that labourer’s death. The Court of Appeal held that the obvious and serious risk of death caused by the trench should have been apparent to Winterton.
     
    An article by Robson et al19 offers the criticism that current GNM tests are not particularly concerned with the context in which a negative event occurs; they are solely focused on evaluating responsibility for specific acts of misconduct. Importantly, Robson et al19 address the element of culpability necessary for conduct to be considered criminal, particularly with respect to distinguishing errors from violations. Errors constitute instances in which ‘one tries to do the right thing but actually does the wrong thing’; violations constitute instances that involve intentional deviations ‘from those practices deemed necessary to maintain the safe operation of a potentially hazardous system’.20 Robson et al19 argue that a negligent doctor should not be criminally liable for a momentary lapse of concentration or an instance of inattention that involved an error in judgement.
     
    Although current law only applies the objective standard of reasonableness, case law has established the key elements that can be used to determine whether negligent act of medical practitioner would be alleged GNM:
  • gross departure from expected standard of care;
  • ignoring reasonable foreseeable obvious and/or serious risks;
  • failing to take actions to allow the risks continuing to endanger patient’s life;
  • the acts of medical practitioners disregard the life of the patient; and
  • the circumstances of the breach of duty (in Adomako all circumstances were emphasised) should have been truly exceptionally bad, ie, no reasonable doctor would have done.
  •  
    It is important that precise direction is given to jury to consider the facts whether the standard of care has really fallen far below the standard and exceptionally bad taken account of the circumstances. The jury must consider whether the defendant doctor should have been aware of reasonably foreseeable obvious and serious risks, but failed to take action. Recent editorial has highlighted the important role of expert opinion in triggering an investigation and determination of a case for prosecution.21 Juries rely upon high-quality expert opinions when making factual determinations regarding whether a medical practitioner’s conduct constitutes GNM.
     
    A criminal conviction has serious and devastating consequences; thus, many countries (both common law and civil law jurisdictions) uphold the doctrine of ‘Presumption of Innocence’. For GNM in clinical context, the facts must be accurately dissected and assessed by competent experts; each element of the offence must be proven beyond reasonable doubt to support a conviction of GNM.

    Primary care physicians worldwide provide a key point of entry to the healthcare system, and are at the forefront of communicating with the community in the context of vaccination campaign and control of infectious diseases.1 2 Primary care plays a fundamental role in building a resilient healthcare system by ensuring people’s continued access to health promotion, disease prevention, essential treatment, long-term rehabilitation, and supportive care.3 Topics relevant to primary healthcare are an increasingly common sight in international medical journals, including Hong Kong Medical Journal (HKMJ).
     
    COVID-19 (coronavirus disease 2019) has presented an unprecedented dual challenge for primary healthcare in recent years, to respond to the public health threat and simultaneously maintain routine delivery of clinical care and preventive services. A health system’s ability to address the ever-growing care complexity is substantially dependent on the accessibility and coordination of primary healthcare. In Singapore, Public Health Preparedness Clinics, an island-wide network of over 900 primary care clinics and polyclinics, served an epidemiological role through the routine collection of data on community transmission by primary care physicians.4 This approach has added to our understanding of how primary healthcare could contribute to enhancing and tightening disease surveillance. In Europe, primary care physicians coordinate care through active participation in knowledge transfer, integration into crisis management teams, and involvement in strategic responses to the pandemic, which is particularly important for fulfilling shared goals to achieve a high level of resilience.5 Other low- and middle-income settings in Asia have also provided examples of how primary care providers are in a privileged position to utilise a variety of resilience mechanisms including mentor support, peer communication, family encouragement, and community recognition.6
     
    In rural China, there are significant disparities in primary care utilisation among different ethnic minority healthcare providers, together with an association between inadequate clinical competency and poor primary care utilisation. Shi et al,7 writing in HKMJ’s ‘Healthcare in Mainland China’, found that in-service training investments and favourable learning environments are required to develop the capacity and capability required for ethnic minority health practitioners. Meanwhile, concerns have been raised over the difficulties in retaining qualified healthcare professionals in deprived rural communities.8 Furthermore, given the possible widening of inequalities in socio-economic determinants of health, people living in more disadvantaged rural areas are more likely to face poor accessibility of healthcare services and suboptimal physician capacity than that in more affluent urbanised areas as a result of the ‘inverse care law’.9 Previous findings suggested that a lack of physician’s continuing medical education may serve as a notable barrier to satisfactory primary care performance in rural areas.10 These challenges highlight the increasing need for system-wide multisectoral collaboration and partnerships with novel tools to enhance physicians’ engagement in context-specific training and care empowerment.11 Alongside efforts to reconfigure primary care teams to address patients’ barriers to following evidence-based regime and advice,12 improved communication skills are crucial not only in clinical practice but also in public health.13 This will underpin a wider landscape of primary healthcare that incorporates population-wide evidence-based approaches to reducing health inequalities in the context of socio-economic diversity.
     
    From a process of care perspective, there is a greater need for strategies to engage multisectoral efforts to strengthen capacity building within, with and around primary care multidisciplinary teams in joint decision-making and problem-solving.14 Practice-level strategies have been identified in a most recent review of international literature which summarised new approaches to ensure the continuity of regular care provision during the pandemic.15 A novel strategy has been characterised by the integration of digital health (or eHealth) services into practice. These services, which can be delivered via telephone, video consultations, email, text messaging, online portals, or smartphone applications, provide an opportunity to expand seamless access to health services for people in remote areas, and also allow rapid exchange of health information. This enables primary care multidisciplinary teams to respond precisely to specific situations of individuals. With the escalating popularity of wearable devices, digital eHealth platforms, and remote patient monitoring tools, decision support solutions driven by artificial intelligence are beginning to appear in daily primary care, and this will be an exciting growth area in the near future.
     
    Managing care for patients with chronic diseases remains a major challenge in primary healthcare although massive efforts and resources directed to COVID-19 tended to have overshadowed the pandemics of noncommunicable diseases. Low et al16 adopted a constructivist grounded theory design to examine the decision-making experiences of family carers of older people with dementia towards the use of community care services and residential care services regarding a variety of healthcare and illness decisions, including hospitalisation, seeing family doctor, and deteriorating health issues. A deep understanding of patients’ and their caregivers’ decisions about health seeking, daily living, and lifestyle choices will be of critical importance to strengthen the role of primary care practitioners as the gatekeeper to care.
     
    Community outreach is another essential element of primary healthcare that goes beyond clinical care, and the HKMJ’s ‘Healthcare for Society’ section regularly highlights the exemplary work of local doctors and healthcare workers. For example, Dr Ching-choi Lam has made substantial contributions to vulnerable populations across the age spectrum.17 In particular, the Elderly Services Programme Plan provides strengthened community care support for the elderly people to enhance their confidence in living at home and in considering community care as a desirable alternative to residential aged care. This represents a significant paradigm shift in our understanding of how primary healthcare could contribute to tackling the long-term care needs that often arise from multimorbidity, frailty, disability, and dependence to achieve ‘Ageing in Place’. Another example is Dr Yu-cheung Ho, who is dedicated to providing a variety of health-related campaigns and humanitarian work that target poverty and healthcare together.18 The dedication to improve equity in medical services and health outcomes is in line with the ultimate goals of primary healthcare, and support from local healthcare workforce engaging in charitable contributions could further help orient the service delivery to local healthcare needs and priorities.
     
    Primary healthcare will continue to be of paramount value for meeting the healthcare needs of individuals, families, and communities within a larger society. In Hong Kong, with the establishment of the Primary Healthcare Commission and the launch of the Primary Healthcare Blueprint, we are looking forward to concerted efforts among key stakeholders in primary care to create a healthier tomorrow.19

    The liver is a common metastatic site for colorectal, lung, and breast cancers. In addition to palliative chemotherapy, there have been advances in therapeutic options for liver-directed therapies, which can prolong patient survival and may be curative. Since the 1960s, hepatic metastasectomy has provided a glimmer of hope to patients with cancer.1 A study in the 1990s revealed a 5-year survival rate of 37% in colorectal patients who underwent liver resection for treatment of one to three liver metastases.2 Improvements in surgical technique, patient selection, and systemic treatment have allowed liver resection to achieve 5-year survival rates of >50%, compared with approximately 5% for patients who receive palliative chemotherapy alone.3
     
    Currently, resectability is defined as the ability to perform complete (R0) resection with adequate preservation of the future liver remnant. The presence of unresectable extrahepatic disease remains a contraindication to liver surgery. For patients who are not good surgical candidates, attractive options include non-surgical liver-directed therapies such as stereotactic body radiotherapy (SBRT), selective internal radiation therapy, transarterial chemoembolisation, hepatic arterial infusion therapy, and radiofrequency ablation.4
     
    Over the years, the role of SBRT in the management of liver metastases has considerably evolved; it is now considered safe and effective therapy. Additionally, SBRT provides excellent local control of liver metastases and carries a comparatively low risk of treatment-related toxicity.5
     
    Patient selection for SBRT is important. Desirable patient characteristics include good performance status with limited disease burden and adequate non-irradiated liver reserve (≥700 cc). Moreover, there is a need for caution regarding the irradiation of liver metastases adjacent to the luminal gastrointestinal tract, which could result in bowel perforation.6 For better outcomes, desirable patient characteristics include limited extrahepatic disease, lesion size ≤3 cm, and fewer than three hepatic lesions.4 Stereotactic body radiotherapy generally provides favourable local control of hepatic metastases; most authors report achieving approximately 80% local control at 2 years if higher biologically equivalent doses are delivered.5 6 7 8
     
    Stereotactic body radiotherapy is administered using a linear accelerator, which precisely delivers high-dose ionising radiation in the form of mega-voltage photons; the treatment is administered in one to five fractions within 14 elapsed days. The dose closely conforms to the target, leading to rapid dose fall-off outside of the target. Usually, SBRT doses are prescribed to the 80% isodose line, which covers at least 95% of the planned target volume.8 Nevertheless, irradiation of the liver can result in radiotherapy-induced liver diseases, which may lead to liver failure and even death, particularly in cases of re-irradiation. In terms of radiobiology, the liver obeys the parallel architecture model; thus, the risk of radiotherapy-induced liver disease is generally proportional to the mean dose of radiation delivered to normal liver tissue. This risk can be minimised by ensuring high accuracy in respiratory motion management via four-dimensional computed tomography, in combination with active breathing control, abdominal compression, or respiratory gating. On-boarding imaging must be conducted before SBRT to allow for the immediate correction of patient positioning.9
     
    In this issue of the Hong Kong Medical Journal, Choi et al10 conducted a retrospective study of 31 patients with liver metastases treated by SBRT between January 2012 and December 2017. Actuarial in-field local control rates at 1, 2, and 3 years after SBRT were 93%, 55%, and 42%, respectively. The median survival was 32.9 months; the 1-year, 2-year, and 3-year actuarial survival rates were 89.6%, 57.1%, and 46.2%, respectively. The treatment was well-tolerated. The authors concluded that patients receiving post-SBRT chemotherapy had significantly longer overall survival, highlighting the need for multimodal treatment with effective systemic therapy, rather than monotherapy with either method alone. This real-world evidence supports the evolving role of SBRT in the management of liver metastases in Hong Kong. There is increasing clinical interest in the use of SBRT to manage liver metastases; this new direction is accompanied by many challenges and questions. Future prospective studies may shed light on the most effective SBRT treatment sequence, key factors concerning patient selection, and optimal systemic treatment (in combination with immunotherapy and chemotherapy) for patients with liver metastasis.

    The primary goals of a health system are generally regarded as the advancement, restoration, and maintenance of health through efforts to ensure coordinated, sustainable delivery of effective, safe, and people-centred healthcare that involves promotion, prevention, treatment, rehabilitation, and palliation.1 High-quality services delivered by motivated healthcare providers are essential for the achievement of effective universal health coverage in countries at all income levels. However, factors that contribute to the quality of healthcare services are multivariate, complex, and interrelated; they cover a wide spectrum of patient-, provider-, organisation-, and system-level enablers and barriers. A previous systematic review demonstrated the negative consequences of physician unwellness on healthcare system outcomes, including but not limited to worse recruitment and retention, reduced productivity and efficiency, suboptimal patient care quality, higher rates of patient nonadherence and dissatisfaction, and increased risk of medical errors.2
     
    In this issue of the Hong Kong Medical Journal, Gao et al3 used standardised patients and questionnaire interviews to examine the extent to which healthcare quality could be attributed to work motivation among village clinicians in 21 rural counties across three provinces in China. The research demonstrated a positive relationship between village clinicians’ internal work motivation and their clinical performance; this association was stronger with incentives and lighter workload (eg, number of patients per month).3 The study adds to a body of previous work published in our section ‘Healthcare in Mainland China’4 by identifying factors associated with healthcare quality in remote and rural areas in China. It also highlights the contribution of physician work motivation to the delivery of high-quality care.
     
    Physicians have a responsibility to meet the needs of people throughout the healthcare system; they also have a responsibility to make evidence-based, sound clinical decisions. Physicians also make substantial contributions to the advancement of medical knowledge and practical skills by conducting well-designed scientific research. For example, research studies focused on coronavirus disease 2019 (COVID-19) are increasingly led by frontline physicians who seek to gain insights regarding disease transmission, risk factors, screening, clinical diagnosis, immune responses, treatment and pharmaceutical prophylaxis, and vaccines.5 The various high-value functions performed by physicians inevitably require continuous dedication, commitment, and passion. Therefore, work motivation and career satisfaction among physicians have received increasing attention over the years, considering their close relationships with healthcare quality.6 There is increasing empirical evidence regarding the multidimensional factors, context, and processes that may influence a physician’s motivation for work; these aspects exert complex effects on the risks of burnout, turnover intention, and job satisfaction.7
     
    Rapid progress in strengthening health systems and service capacity has led to increased clinical responsibilities and job demands on physicians because of increased patient volume, expanded key performance metric indicator targets, and decreased autonomy. Additionally, physician workloads can substantially increase during public health emergencies. For example, the COVID-19 pandemic has presented new challenges that require novel solutions with respect to infection prevention, early recognition, rapid identification, disease control, rehabilitation, and resilience.8 9 10 11 12 These changes have been addressed by research conducted in Hong Kong. A recent territory-wide cross-sectional survey revealed a high prevalence of burnout among physicians who had completed specialist registration within the past 10 years and among residents-in-training, as well as a high level of depression among junior physicians who reported substantial dissatisfaction with their current job positions.13 A review of international literature highlighted the prevalences of sleep deprivation and circadian disorders related to prolonged working hours; these problems affect physician health, leaving physicians vulnerable to significant work-life imbalance, psychological stress, and burnout.14
     
    In remote and rural areas where limited healthcare resource availability remains a recurring key challenge, the achievement of desired health outcomes is dependent on whether physicians can deliver a broad spectrum of person- and family-centred care in the community. Rural physicians play an important role in the delivery of community-based disease prevention and health promotion in response to community healthcare needs. Observational evidence from China suggests that rural physicians with higher workloads tend to deliver less frequent follow-up care; this phenomenon may be explained by reduced initiative and motivation related to the perception of an increased daily clinical workload, particularly among physicians who have not yet achieved clinical proficiency in managing complex encounters.15 The results of a nationally representative survey of physicians in the United States also led to speculation regarding the associations of intrinsic motivation factors with physicians’ career enjoyment, life satisfaction, and clinical commitment.16
     
    Physician attitudes and behaviours with respect to following clinical guideline recommendations are presumed to strongly influence healthcare outcomes. The inability or failure of physicians to initiate or intensify therapy when indicated, despite clear recognition of the problem (ie, ‘clinical inertia’), represents a common and major barrier to efficiency and effectiveness in disease management.17 18 A recent observational study indicated that efforts solely focused on increasing the proportion of tertiary educational attainment among Chinese rural physicians may not directly translate into strong motivation and active commitment to the provision of clinical services, considering the potential for concurrent clinical inertia and workload-related factors.15 Thus, there may be a need for a systematic approach that incorporates the use of facilitators (eg, computerised decision support systems and standardised clinical management protocols), provision of carefully and appropriately designed incentives, and implementation of CME/CPD (continuing medical education/continuous professional development) programmes throughout each physician’s career,18 in addition to the initial medical training.
     
    There remains a vast array of factors to consider when attempting to improve healthcare sustainability and enhance physician satisfaction over time. For instance, practice structure and ownership; relationships with colleagues within and outside the practice; and the content, quantity, and speed of work have been identified as factors that influence physician career satisfaction.19 Some conceptual frameworks may provide useful perspectives, such as the Knowledge-Attitude-Behaviour-Result model, Awareness-Agreement-Adoption-Adherence model, Physician Guideline Compliance model, and Regulatory Focus Theory.18 These frameworks may help to guide interventions that overcome barriers to physician motivation and satisfaction. Multiple randomised clinical trials have been conducted to explore innovative approaches that promote physician well-being. A study at the Mayo Clinic in the United States demonstrated that self-facilitated physician small-group meetings involving reflection, shared experience, and small-group learning produced significant improvements in burnout, depressive symptoms, and job satisfaction.20 As noted in a previous systematic review, physicians with higher levels of career satisfaction are more likely to dedicate their full attention to patients’ healthcare needs and provide better patient care.6
     
    The current findings emphasise the importance of promoting physical, emotional, and spiritual well-being among physicians to ensure empathy and compassion in patient care, while minimising and preventing medical errors and malpractice. Further research concerning the extent to which relationships of physician motivation and satisfaction with healthcare quality vary across levels of healthcare and among medical specialists will be of interest to the readers of the Hong Kong Medical Journal. We also look forward to receiving additional evidence from pragmatic implementation studies that can provide insights regarding optimal strategies for improving physician motivation and satisfaction, particularly in the post–COVID-19 era.

    The Hong Kong Medical Journal (HKMJ) was first indexed on MEDLINE in 2000 and has developed over the years to now have a Journal Impact Factor of 3.125 (Clarivate, 2022). The HKMJ is an important forum for the dissemination of both local and international medical research and, with the support of the Hong Kong Academy of Medicine and the Hong Kong Medical Association, is freely accessible online with no publication charges. The HKMJ constantly evolves, and the Editorial Board take strategic decisions to keep the content contemporary and interesting for our readers.
     
    Healthcare changes rapidly. New drugs, techniques and guidelines can be bewildering. Perspectives exhibit a new and original viewpoint on available issues, basic concepts, or widespread notions on a particular topic, suggest and encourage a new speculation, or discuss the implications of a newly implemented innovation. Perspectives may focus on common advances and coming directions on a topic, and may include unique information along with personal experience and point of view. Perspectives can be just that or an opinion or commentary. Similar to the Perspective section of the New England Journal of Medicine, this new article type for HKMJ will cover timely and relevant topics in Medicine and Healthcare presented in a brief manner.1 These are scholarly articles which denote a personalised point of view or a new perspective on a specific topic. Perspectives may also be narrative reviews of the literature discussing recent developments in a specific topic or guiding practice for clinicians as our new Perspective article type. Although these articles do not amount to unique research, they can be clinically elucidating and still add value to the scientific literature, encourage discourse, and improve the overall impact of the journal.
     
    Perspective articles mainly constitute an opinion which exhibits the author’s viewpoint on the strengths and weaknesses of a speculation or scientific theory and ought to be constructive criticism backed by evidence intended to promote scientific dialogue that challenges the current state of knowledge in a specific field. The editors will also consider perspective articles discussing timely clinical or health topics, or research studies published elsewhere. The editors request, however, that authors do not principally aim to discuss their own work and try to be balanced in their opinions.
     
    Commentaries can also be considered under this banner but tend to be shorter (≤1200 words) and should draw attention to or critique a previously released article, book, report or guideline, using anecdotal evidence or the author’s personal experience to highlight points of wider relevance to the field.
     
    Perspective articles should be generally <2000 words and usually include one figure or table, and will be peer reviewed.
     
    While editors may invite such articles from reviewers or experts in the field, authors should consider writing a Perspective or Commentary in situations where: the topic is of broad concern to a wider audience or to the scholarly community in general; the author wishes to present opinions and ideas or describe an innovation that has not yet been broadly implemented; or the author wishes to provide an in-depth discussion of a topic or literature review that would be too lengthy for a commentary but does not amount to a systematic review.
     
    Whether you are writing a Perspective detailing an innovation, or providing your opinions or ideas from a particular perspective, decide on the message you wish to express and organise your thoughts logically. Perspectives are still scholarly articles, although they denote a personalised point of view or a new perspective about available research; references, figures and tables should be used sparingly to support key facts. A number of journals have adopted similar article types and we feel that Perspectives is an innovation that will prove very popular with readers. Guidelines on format and presentation are now available in our Guide for Authors (https://www.hkamedtrack.org/hkmj/guide_for_author). What are you waiting for?

    Invasive pneumococcal disease (IPD), a major public health problem worldwide (including in Hong Kong),1 2 3 is a severe and potentially life-threatening infectious disease caused by the gram-positive bacterium, Streptococcus pneumoniae.1 2 The clinical manifestations of acute IPD vary among organ systems involved; they include severe and potentially fatal infections such as community-acquired pneumonia, meningitis, and sepsis.2 In Hong Kong, pneumonia has consistently been the second leading cause of death since 20124; it is associated with higher rates of hospitalisation and higher healthcare costs, particularly among older adults.5 6 Despite appropriate treatment, up to 50% of IPD survivors experience long-term complications, including respiratory, cardiovascular, and neurological sequelae.7 Invasive pneumococcal disease is associated with substantial healthcare and economic burdens; thus, it represents an acute public health problem in Hong Kong, particularly amid the coronavirus disease 2019 (COVID-19) pandemic. There is an urgent need to develop effective strategies that can mitigate the potential threat of an IPD outbreak.
     
    Burden of invasive pneumococcal disease in Hong Kong
    Invasive pneumococcal disease has been a statutorily notifiable disease in Hong Kong since January 2015.8 Between 2015 and 2019, the Centre for Health Protection recorded a median of 187 (range: 162-190) IPD cases per year; the emergence of COVID-19 in 2020 led to a dramatic decrease in the number of IPD cases in Hong Kong (Fig 1).3 However, the current IPD burden is severely underestimated because of underdiagnosis, and a high index of suspicion for IPD is a central aspect of differential diagnosis. Because the clinical symptoms of IPD overlap with the symptoms of other respiratory illnesses, inexperienced physicians may experience challenges regarding specimen collection (ie, samples may be inappropriately or inadequately collected); such challenges contribute to the underutilisation of diagnostic tests and underreporting of IPD.
     
    Because S pneumoniae is transmitted by direct contact with respiratory secretions from patients with IPD and from healthy carriers,2 9 public health measures (eg, mask wearing, social distancing, travel restrictions, and quarantine) that were implemented to prevent the transmission of severe acute respiratory syndrome coronavirus 2 also reduced the spread of S pneumoniae; thus, the number of IPD cases has decreased since the beginning of 2020 (Fig 1).3 As Hong Kong emerges from the COVID-19 pandemic, the gradual relaxation of public health intervention measures is expected to result in an increased number of IPD cases. Moreover, seasonality could contribute to a sudden increase in IPD cases because respiratory diseases (eg, pneumococcal infection and influenza) are generally more prevalent during winter and early spring.10 11 Notably, Israel experienced a nationwide outbreak of S pneumoniae serotype 2 between 2015 and 2019, despite the availability of vaccination programmes.12 Such outbreaks highlight the need to formulate effective strategies for early disease prevention.
     

    Figure 1. Number of invasive pneumococcal disease cases in Hong Kong, 2009-20223
     
    Pneumococcal vaccination in Hong Kong
    Two types of pneumococcal vaccines are available to prevent IPD: pneumococcal polysaccharide vaccines (PPSVs) and pneumococcal conjugate vaccines (PCVs). The 23-valent PPSV (PPSV23) contains purified capsular polysaccharide antigens from 23 distinct S pneumoniae serotypes, whereas PCVs—including PCV13, PCV15, and PCV20—contain purified capsular polysaccharide antigens from 13, 15 or 20 serotypes of S pneumoniae conjugated to a nontoxic variant of diphtheria toxin (CRM197), along with aluminium phosphate as an adjuvant.13 14 In contrast to PPSVs, the conjugated complexes contained in PCVs exert long-term protection because they are able to stimulate T-cell-dependent immune response to generate immune memory for the specific S pneumoniae serotypes covered by the vaccine.15 Importantly, clinical trials and real-world evidence have consistently demonstrated the effectiveness of PCV13 in providing serotype-specific protection against IPD.2 13 16 Although IPD can occur at any age, an increased risk of onset is associated with various factors; mortality is substantially higher in children <2 years and adults aged ≥65 years.10 13 In Hong Kong, the current recommendations for pneumococcal vaccination by the Centre for Health Protection prioritise adults aged ≥65 years with high-risk conditions,17 consistent with recommendations from the United States Advisory Committee on Immunization Practices.18 Specifically, pneumococcal vaccine-naïve individuals with high-risk conditions are recommended to receive one dose of PCV13, followed by one dose of PPSV23 at 1 year after PCV13 vaccination.17
     
    Since 2017, the Hong Kong government has provided free or subsidised pneumococcal vaccination to eligible individuals through the Government Vaccination Programme (GVP) and the Vaccination Subsidy Scheme (VSS).19 Despite this governmental support, rates of vaccine uptake and participation in GVP and VSS remain low.19 Concerns regarding vaccine efficacy, poor understanding of the disease, and lack of clarity regarding vaccine schedules are some of the major challenges that limit pneumococcal vaccination among adults in Hong Kong.19 Another limiting factor is vaccine hesitancy related to perceived vaccination burden and fatigue.20
     
    Current serotype burden in Hong Kong
    Data from continuous surveillance of pneumococcal serotypes have facilitated analyses of serotypes isolated from the community, which have yielded insights regarding the effectiveness and limitations of pneumococcal vaccination programmes. Since the implementation of pneumococcal vaccination in Hong Kong, the incidence of IPD involving vaccine-covered serotypes has considerably decreased. However, because of low vaccination rates in recent years, PCV13-covered serotypes (including serotypes 3, 19F, and 19A) have been identified in half of all reported IPD cases (Fig 2).3 21 22 23 Importantly, although it is covered by PCV13 and PPSV23, serotype 3 remains a major cause of IPD because its unique polysaccharide capsule resists detection by vaccine-induced antibodies.24 Moreover, the emergence of non-vaccine serotypes (Fig 2; ie, serotype replacement) also poses a public health threat.23 25
     

    Figure 2. Number of reported pneumococcal serotypes among IPD patients aged ≥18 years in Hong Kong, 2019-20223
     
    A higher-valency vaccine for broader protection against invasive pneumococcal disease
    Considering the current challenges in Hong Kong, a higher-valency PCV (eg, PCV20) could partly address the potential public health problem associated with serotypes that are not covered by the Hong Kong vaccination programme. The 20-valent PCV provides broader protection against IPD; a single dose contains seven new serotypes, in addition to the serotypes covered by PCV13.26 Phase 3 studies of clinical efficacy have demonstrated that PCV20 is noninferior to PCV13 and PPSV23 across a subset of age-groups, regardless of pneumococcal vaccination history and high-risk conditions.27 28 Importantly, PCV20 can be concurrently administered with influenza and COVID-19 vaccines.26
     
    In October 2021, the Advisory Committee on Immunization Practices recommended one dose of PCV20 alone, or serial immunisation (PCV15, followed by PPSV23), for all PCV/PPSV-naïve adults aged ≥65 years and PCV/PPSV-naïve adults aged 19-64 years with high-risk conditions.26 The implementation of a PCV20 single-shot vaccination programme could be a cost-effective strategy to address the current burden of IPD cases that involve serotypes covered by PCV13 and serotypes unique to PCV20.29 Furthermore, the convenience of a simplified vaccination schedule could improve vaccine uptake.
     
    Overcoming challenges in Hong Kong and implementing preventive strategies against invasive pneumococcal disease
    The government and physicians play key roles in promoting pneumococcal vaccination and improving vaccine uptake, particularly among older adults. Because the perceived low burden of IPD may reduce the rate at which physicians recommend vaccination for their patients,30 there is a need to improve physician awareness regarding IPD and the benefits of pneumococcal vaccines for individuals with an increased risk of IPD.
     
    Continuing medical education programmes for physicians could cover periodic updates regarding the IPD burden in Hong Kong, current pneumococcal vaccine schedules, proper sample collection methods, and appropriate diagnostic tests for confirmation of IPD in patients with relevant symptoms. These initiatives can improve early diagnosis and treatment of IPD, facilitate accurate data collection regarding IPD incidence, and help to manage the underestimated burden of IPD. Additionally, government-led public education campaigns that focus on bridging knowledge gaps with respect to (i) the public health impact of IPD (a vaccine-preventable disease), and (ii) vaccine accessibility through GVP and VSS, could help to overcome vaccine hesitancy and improve vaccine uptake in Hong Kong.

    In Hong Kong, it is government policy that no one is denied adequate medical care due to a lack of means, making Hong Kong a proud provider of almost universal access to medical services. Nonetheless, these medical services provided by the Hospital Authority mostly involve specialist care that eventually dominates a 'treatment-based' patient care system and plays down preventive care. With a rapidly ageing population1 and escalating burden of chronic diseases, the impact of complicated disease is compounded by neglect of care for patients who are otherwise well but at an early stage of disease. This results in increasingly long waiting times for 'routine' specialist out-patient care.2
     
    As evidenced by Hong Kong’s Domestic Health Accounts in 2019/20, only around 17% of the total public current health expenditure was spent on primary healthcare, with the remaining 83% spent on secondary and tertiary healthcare services.3 This implies that most individuals will not undergo individual health assessments because they are rarely able to obtain routine individualised preventive care advice from doctors about issues such as vaccination scheduling, cancer screening or chronic disease screening.4
     
    Data from the Hong Kong Population Health Survey 2014/15 revealed that 54.1% and 47.5% of patients with diabetes mellitus (DM) and hypertension, respectively, were unaware of their condition prior to the health examination that formed part of the survey.5 Even worse, patients known to be pre-diabetic did not receive the care that may have prevented their progression to DM (an annual conversion rate of approximately 5-10%).6 7 With no alternative, public hospitals must care for these patients, with approximately 40 000 per year newly diagnosed and referred.8 The dilemma is how to tackle the challenge of maintaining public health with minimal intervention in a city where the number of patients with chronic disease is projected to reach 3 million by 2039.9
     
    Currently, Hong Kong has an underdeveloped primary healthcare system with the private sector providing around 70% of all services.10 Compared with 11 developed countries, Hong Kong lacks a mature family doctor network, a core component of continuous care provision that can improve chronic disease management and prevention.11 The concept of 'family doctor for all' is one of the key visions of the Primary Healthcare Blueprint issued by the Government of the Hong Kong Special Administrative Region in December 2022. The plan is to formalise and link the Primary Care Directory and subsidised services, not only for Elderly Health Care Vouchers, vaccination and cancer screening but also chronic diseases, with matched family doctors.
     
    In 2023, the Health Bureau will pilot the Chronic Disease Co-Care Scheme announced in the Policy Address 2022. The objective is to make use of the community network to improve (1) screening, (2) diagnosis of pre-diabetes, early DM and hypertension, and to (3) match patients with a family doctor listed in the Primary Care Directory. There is evidence that for individuals with early-stage or asymptomatic chronic disease, lifestyle modification and early medical intervention are essential.12 Therefore, the programme will coordinate and subsidise both local and professional support for patients to receive holistic care and lifestyle interventions from family doctors and District Health Centres. The proposed packages will encourage individuals to build a long-term relationship with a self-selected family doctor supported by a community coordinator.
     
    A new statutory body to be established in 2024, the Primary Healthcare Commission, will develop district-based healthcare and drive the 'family doctor for all' policy in an attempt to shift the focus of patient care towards prevention by increasing public funding. Through coordination and networking, the future healthcare model will provide public access to screening, health planning, community care and individual advice/intervention by a family doctor. This will be achieved through: (1) consolidation of existing services provided by the Department of Health, (2) purchased private services, (3) enhanced training in family medicine, (4) coordination of community networks, and (5) better governance including bi-directional referrals between primary and secondary care. Setting up of clinical standards and performance monitoring will be core functions to build public confidence in the purchased or network services. The Primary Care Register for family doctors will be formalised and structured for the general public under a legal framework. Furthermore, through the Electronic Health Record Sharing System and the eHealth App, more initiatives rolled out via digital healthcare will increase connections and networks available within the community. With a mature family doctor system, more subsidised and convenient disease prevention programmes can be initiated to improve public health.
     
    Hong Kong has a dual track medical system, but 'treatment-based' healthcare is not sustainable in the provision of quality care. The Primary Healthcare Blueprint aims to steer our future multidimensional development to include a prevention centric system. The reform requires the full support of our professionals who can share common goals in building trust between professionals and the community, as well as pursuing timely interventions for people of all ages within a strong primary healthcare system.

    Medical manslaughter in Hong Kong: what now?

    Medical manslaughter in Hong Kong: what now?

    Healthcare professionals are not above the law. In the event of substandard medical care that resulted in patient death, it is only right that society and families be provided opportunities to seek explanation, redress, justice, and closure. Civil proceedings and professional regulatory mechanisms are commonly pursued avenues recognised by healthcare professionals as proportionate; criminal law intervention is justified in some circumstances, but it is a more unsettling approach.1
     
    Criminal law intervention is unsettling not so much because of the actual imposition of criminal penalty where deserved but because of the very thought that one could be a single mistake away from being charged for a crime, as well as the adverse effects that such fear may have on professional culture, clinical practice, and patient welfare. It is also unsettling because of uncertainties regarding the threshold for prosecution.
     
    Despite criticisms concerning its circularity, vagueness, and the arguable lack of requirement for a clearly culpable mens rea, the offence of gross negligence manslaughter (GNM) has survived repeated calls for legal reform, and it continues to be applied in ‘medical manslaughter’ cases.1 As for other crimes, the decision to prosecute must consider two factors: first, whether there is a reasonable chance of securing a conviction, and second, whether the public interest requires a prosecution to be pursued.2
     
    The first factor is related to the determination of whether there is sufficient evidence to prove all ingredients of the offence. As established in the British case of R v Rose, a conviction of GNM requires the court to be satisfied that (in addition to the basic elements of civil negligence) it was reasonably foreseeable to the suspect that the breach of duty would give rise to a ‘serious and obvious risk of death’, and that the circumstances of the breach were ‘truly exceptionally bad and so reprehensible… that [the breach] amounted to gross negligence and required criminal sanction’. An ‘obvious’ risk must be clear and unambiguous based on knowledge available at the time of the breach, rather than one which might become apparent on further investigation. Importantly, a recognisable risk of something serious is not the same as a recognisable risk of death.3 Whether and how these principles might have been followed in other common law jurisdictions remain to be discovered. A hypothetical question to ask could be whether the circumstances of an inadvertent omission of drug prescription are truly exceptionally bad and so reprehensible as to warrant prosecution.
     
    The second factor is related to the fundamental principle that not all offences for which there is sufficient evidence should automatically be prosecuted; the public interest must require such an approach. When evaluating the public interest balance, an inexhaustive list of factors are considered, subject to the circumstances of the case. The exercise of this discretionary power is complex and demanding; even experienced prosecutors may have difficulty agreeing on a consistent approach to GNM cases.4 It is of note that whilst the public interest is unlikely to allow of a disposal less than prosecution when the victim has suffered significant harm, the suspect’s level of culpability should also be considered. The problem is that an ‘honest’ mistake—made without intent to cause harm or recklessness as to the risk of harm—is exactly what might be caught (or not) under the arguably elastic and arbitrary scope of GNM.
     
    Because GNM is not an offence specific to medical cases, there is no reason to expect routine consideration regarding the impact of criminalising medical error on the broader public interest. However, poor morale, staff attrition, loss of trust, the rise of defensive medicine, and the suppression of a learning culture are highly plausible consequences of over-criminalisation with serious implications for quality of care and patient safety.1 In the United Kingdom, a series of high-profile cases caused sufficient public outcry that the Secretary of State for Health and Social Care instigated a rapid policy review into the application of GNM in healthcare5; another review was later commissioned by the General Medical Council.6 Neither review was intended to recommend changes in the law; both were undertaken to identify potential improvements within the existing legal framework.
     
    Both reviews found that, although the threshold for prosecution has been set appropriately high following the decision in R v Rose, there remained a perception among healthcare professionals that the legal test has not been applied in a consistent manner, and that individuals were under investigation where the prospect of prosecution or conviction may be low. Both panels saw a need to enhance the transparency and understanding of the law, as well as the threshold for prosecution so as to provide assurance regarding how decisions are made. A series of guidelines was subsequently issued by the Director of Public Prosecutions.
     
    The reviews also highlighted the central role of expert opinion in triggering an investigation and in determining whether a case should be prosecuted. Because problems with expert testimony may not be uncovered until trial or appeal, an unsound or biased opinion could potentially subject a healthcare professional to otherwise avoidable legal proceedings. Indeed, questions were raised regarding the use of expert witness opinion during the pre-trial stage, the competence and conduct of some experts, the experts’ understanding of the law, and their understanding of their duties to the court. In Hong Kong, a training course for expert witnesses is available through the Hong Kong Academy of Medicine. Formal mechanisms to ensure the recruitment of competent expert witnesses, the engagement of a dedicated panel of 'super-experts' at the pre-trial stage, and the scrutiny of opinions regarding quality would be welcome.
     
    Finally, the reviews emphasised the importance of maintaining an open and just culture of candour and learning. Families who feel that they have been denied information are more likely to seek answers through legal processes; thus, the method in which healthcare service providers manage the aftermath of a patient’s death should be carefully considered. Legal protection may be given to statements that arise during internal proceedings, thereby creating a safe space for healthcare professionals to discuss and learn from their mistakes.
     
    There is no doubt the criminal law serves important functions in safeguarding patient welfare, but it is also a blunt instrument that can destroy the fabrics and ideals of a healthcare system if not applied judiciously. Medical manslaughter cases should be handled with exceptional care—not because healthcare professionals are an exception to the law, but because of the exceptional damage that a single case can do. Neither medicine nor the law operates in a vacuum. Both earn society’s trust and deference through not their power but the good they do, and both should reckon with each other’s unique strengths and values, limitations, and challenges. Now that the likelihood of what happened in the United Kingdom being repeated in other places is all but real, it will be up to policymakers to determine how best to calm nerves and learn from lessons learned elsewhere.

    Antimicrobial resistance (AMR) has been declared one of the top ten global public health threats facing humanity by the World Health Organization (WHO) in 2019.1 The WHO has estimated that, by 2050, the number of deaths attributed to AMR will be as high as 10 million each year, exceeding those caused by cancer (8.2 million).2 The coronavirus disease 2019 (COVID-19) pandemic has exacerbated the AMR situation globally. In 2020, the Centers for Disease Control and Prevention of the United States reported more cases of carbapenem-resistant Acinetobacter (increased by 78%), antifungal-resistant Candida auris (increased by 60%), and carbapenem-resistant Enterobacterales (increased by 35%) than in 2019, possibly due to more and sicker patients during the pandemic who required more frequent and longer use of catheters and ventilators, personal protective equipment and laboratory supply challenges, fewer healthcare staff, and longer lengths of stay.3 Outbreaks of multidrug-resistant organisms, including carbapenem-resistant Acinetobacter baumannii,4 5 C auris6 and Enterobacterales,7 as well as vancomycin-resistant Enterococcus,8 9 have been reported in healthcare facilities. In a systematic review that identified 17 outbreaks during the COVID-19 pandemic caused mainly by carbapenem-resistant Acinetobacter baumannii and C auris, inadequate personal protective equipment or hand hygiene adherence, personal protective equipment shortage, and high antibiotic use were the most commonly reported modifiable factors contributing to the outbreaks.10 In some countries, antimicrobial stewardship programmes in hospitals were adversely affected or even suspended.11 12 Hong Kong is not immune to these challenges, and substantial resource have been diverted to tackle the COVID-19 pandemic.
     
    Despite these constraints, considerable progress has been made in Hong Kong, according to directives as described in the Hong Kong Strategy and Action Plan on Antimicrobial Resistance (2017-2022).13 The AMR Information System was established in October 2021 to collate, analyse, and report data from various departments of the Hong Kong SAR Government and the Hospital Authority. This system provides well-organised and transparent access to surveillance data on the human side covering AMR and antimicrobial use (AMU). Antimicrobial resistance and AMU involving food animals are also now included in a regular surveillance programme, and a long-term food surveillance system on AMR has been established. Enhanced regulatory measures against the illegal sale of antimicrobials, health promotional activities, and collaboration between healthcare providers and community partners to advocate appropriate use of antimicrobials have been effective. The percentage of total supply of antibiotics to community pharmacies gradually decreased from around 18.5% in 2016 to 5.6% in 2021. Under the Antibiotic Stewardship Programme in Primary Care initiative, new guidance notes and patient information sheets on seven common infections have been developed to drive appropriate antibiotic use by primary care doctors. Coupled with antimicrobial stewardship programmes implemented in hospitals, the proportion of the total antimicrobial supply classified as the “Access” group under WHO classification (ie, those showing lower resistance potential than antibiotics in the other groups) reached 61.9% in 2020 and 65.8% in 2021 in Hong Kong, above the 60% target set by the WHO. Data from the Hospital Authority in 2021 reflected that 94.5% use of two broad spectrum antibiotics, namely piperacillin/tazobactam and meropenem, were found to be appropriately used in medical, surgical and orthopaedic and traumatology specialty of acute hospitals.14
     
    The Hong Kong SAR Government is also tackling AMR on other fronts. For animal health, a policy is being prepared for “veterinary prescription-only medication supply”.14 To reduce the incidence of infection, infection prevention and control training is in place, with over 30 000 attendances per year in the human health sector and 6000 in the food sector. The Department of Health has also been offering free seasonal influenza vaccination and pneumococcal vaccination to eligible target groups, which helps reduce potential complications from these diseases, such as secondary bacterial infections and AMU. Under the “One Health” framework, the Department of Health, the Agriculture, Fisheries and Conservation Department, and the Food and Environmental Hygiene Department have joined together to launch publicity activities to echo the annual World Antibiotic Awareness Week to promote proper use of antibiotics. To encourage research, AMR has been included as one of the thematic priorities in the open call for investigator-initiated projects under the Health and Medical Research Fund, and 33 related projects have been funded in the 2017 to 2020 round of open call applications.
     
    Nevertheless, many challenges to further improve the AMR situation remain. A sustained high rate of methicillin-resistant Staphylococcus aureus bacteraemia was detected after 48 hours of admission in public hospitals in the past few years. Data reported to the Centre for Health Protection indicate that the number of cases of carbapenemase-producing Enterobacteriaceae discharged to residential care homes for the elderly has been doubled from 242 cases in 2019 to 526 cases in 2021. Since the first case of C auris, an emerging multidrug-resistant fungus, reported in Hong Kong in July 2019, more cases and outbreaks in public hospitals have been reported.15 16 Despite a reduction of AMU among community pharmacies and general practitioners in 2020 and 2021, it is possible for rebound of respiratory illnesses and resurge of AMU in these settings after relaxation of public health measures for COVID-19. Health promotion on AMR is still needed: in a survey of the general public, 54.0% of respondents mistakenly identified cold and flu as treatable with antibiotics.17 Moreover, comprehensive data on AMU and AMR among general practitioners are lacking. There is also limited scientific knowledge on the role of the environment in the evolution of AMR.
     
    In his Policy Address on 19 October 2022, the Chief Executive of Hong Kong pledged to promulgate a new plan on AMR for the next 5 years. To tackle this public health threat and address challenges ahead, Hong Kong Strategy and Action Plan on Antimicrobial Resistance (2023-2027)14 adopts six key policy areas: strengthen knowledge through surveillance and research; optimise use of antimicrobials in humans and animals; reduce incidence of infection through effective sanitation, hygiene and prevention measures; improve awareness and understanding of AMR through effective communication, education and training; promote research on AMR; and strengthen partnerships and foster engagement of relevant stakeholders. Among the 21 objectives in the Action Plan, five are identified as priority interventions: surveillance and control of AMR in ready-to-eat food; strengthening regulation of record keeping for prescription-only antimicrobials in community pharmacies; enhancement of antimicrobial stewardship programme in public hospitals; a territory-wide decolonisation programme for multidrug-resistant organism in residential care homes for the elderly; and conducting regular surveys among the general public on AMR to inform strategies on health promotion.
     
    The theme for the 2022 World Antibiotic Awareness Week (18-24 November) is “Contribute Together to Combat Antimicrobial Resistance!”. Antimicrobial resistance is everyone’s business. The Hong Kong Centre for Health Protection has a dedicated page (https://www.chp.gov.hk/en/features/47850.html) with the latest information on AMR for the general public and healthcare workers. With concerted effort from healthcare professionals and all other concerned parties, we can combat AMR together in the coming 5 years and beyond.

    Status of COVID-19 worldwide and in Hong Kong
    As of November 2022, there have been >600 million confirmed cases of coronavirus disease 2019 (COVID-19) worldwide, including 6 million deaths, since the pandemic began in 2020.1 In Hong Kong, the number of cases has reached >2 million, with >10 000 deaths. Since the initiation of the vaccination programme in 2021, >94% and >83% of the population have received the first and third doses, respectively.2 In addition to its impacts on infected individuals, the COVID-19 pandemic has affected the general public and physicians.3 4 5
     
    Relationship between the COVID-19 pandemic and cancer
    Patients with cancer are more aware of the impact of COVID-19 because of their increased risk of infection. This risk of infection arises from factors such as the presence of an immunocompromised status related to disease or treatment, the nature of cancer as a major co-morbidity that enhances the risks of COVID-19–related morbidity and mortality, and the need for frequent visits to medical centres to receive anticancer treatment and cancer-related care.6 7 A study conducted in China showed that patients with both COVID-19 and cancer had 3.5-fold greater odds of requiring mechanical ventilation, intensive care unit admission, or death, compared with healthy individuals.8 Patients with cancer also had a higher risk of COVID-19 infection and experienced worse outcomes, compared with patients who did not have cancer.9 10 Additionally, one study showed that the onset of COVID-19 could lead to higher mortality (24%) among patients with cancer than among patients without cancer (3%).10 11
     
    Impact of COVID-19 on cancer screening
    The COVID-19 pandemic has led to reductions in cancer screening services in relation to the suspension of non-urgent medical services, rescheduling to focus on COVID-19–related services, and reduced patient motivation to seek care.12 13 14 Affected services include colorectal, cervical, lung, and prostate cancer screenings.
     
    For example, colorectal cancer screening capacity in the United States has decreased by 86%, and up to 1500 colorectal cancer cases have been missed or delayed in Australia during the COVID-19 pandemic thus far.12 The effectiveness of colorectal cancer screening services is compromised because there is an increased risk of COVID-19 transmission associated with endoscopy and the exposure of vulnerable people to the hospital environment. These impacts have been reported in multiple countries worldwide, including the United States, United Kingdom, Ireland, Australia, and Italy.12 Additionally, one study showed that a large proportion of women in Hong Kong have never undergone cervical cancer screening; this lack of screening has been exacerbated during the COVID-19 pandemic because of restricted access to medical centres.13 Social distancing and concerns about potential exposure have deterred women from seeking clinical care, thereby reducing in-person screening.10 Another study revealed the potential for missed cancer diagnoses (prostate, 19.7%; colorectal, 10%; and lung, 3%) because of the COVID-19 pandemic in Hong Kong.14
     
    Impact of COVID-19 on cancer treatment and patient life
    The COVID-19 pandemic has had diverse effects on patients with cancer; the greatest impacts have involved effects on patients’ lives and access to cancer treatment modalities. Researchers in Hong Kong recently published the results of a multidisciplinary cross-sectional survey that examined the real-world impact of the pandemic on patients with cancer in May 2020.15 The survey found that patients accepted increased physical distance from medical staff during consultations; patients were able to refill their medications without oncologist consultations. Although some patients receiving chemotherapy or radiotherapy chose not to modify their treatment plans, many patients were willing to balance a change in treatment efficacy or side-effect profile with the ability to undergo out-patient treatment. Among patients with cancer, social distancing measures during the pandemic have changed attitudes and experiences related to medical consultation and cancer treatment; these changes have tended to continue as the pandemic severity has declined.15 16 17
     
    Implications for cancer care during the pandemic
    Research has shown that although cancer services continue to function with adaptive measures and patient acceptance, many patients are hesitant to visit hospitals. This hesitance is related to inadequate information regarding COVID-19 among patients with cancer, particularly with respect to hospital safety measures focused on COVID-19.16 Therefore, patients with cancer should receive timely information about COVID-19 from official sources, through various channels (eg, the internet and social media), regardless of their age and socio-economic status.
     
    Research findings have also emphasised the real-world needs of patients with cancer in terms of individualised dietetic and occupational health assessments, early in-patient or out-patient interventions, and self-help materials for cancer care developed in the context of the pandemic. Such considerations should include telemedicine, which has become popular during the pandemic; because it sometimes cannot be accessed and understood by underprivileged individuals (eg, older adults and less educated patients), telemedicine should not fully replace conventional physiotherapy and rehabilitation.17 The issue of telemedicine was also addressed in a study focused on new cancer diagnoses. Among patients who experienced difficulty understanding their cancer diagnosis (eg, cancer type, stage, and treatment options), the use of telemedicine may lead to increased anxiety and confusion. Thus, clinical visits are preferable for new patients.18
     
    The decision to continue or discontinue treatment (chemotherapy or surgery) is a key consideration for patients with cancer who may have an increased risk of infection during the pandemic. The results of some studies suggest that adjuvant chemotherapy or surgery can be postponed for patients with cancer who exhibit stable disease, whereas the results of other studies suggest that those aspects of treatment should be continued to prevent COVID-19 transmission. The findings of one study indicated that adjuvant chemotherapy with curative intent should be maintained for early-stage cancer.18 Robust precautionary measures should be implemented for chemotherapy infusion areas (eg, nucleic acid testing, quarantine, and isolation) to protect immunocompromised patients.18 Nevertheless, that study did not include patients with cancer who received treatments in private clinics. Moreover, future studies should cover longer periods of time (ie, not limited to the first wave of the COVID-19 pandemic), considering that there were five waves of COVID-19 in Hong Kong before November 2022.19 In addition to clinical outcomes, patient-reported outcomes should be explored among patients with cancer.20 Additional studies are needed regarding the long-term impact of the COVID-19 pandemic on cancer care to determine how it may affect the cancer burden in Hong Kong during the post-pandemic era.
