OBJECTIVES. To explore factors associated with length of stay, and secondarily to explore the potential of enhanced diagnostics to address respiratory disease burden in children.
DESIGN. Prospective study.
SETTING. A university teaching hospital in Hong Kong.
PATIENTS. Data from 475 children with respiratory tract symptoms or fever admitted to Prince of Wales Hospital, Hong Kong from November 2005 to April 2007.
MAIN OUTCOME MEASURES. Aetiological diagnoses based on enhanced diagnostics and their association with clinical information.
RESULTS. Data from 469 subjects showed that major presentations were fever (84%), cough (72%), and runny nose (64%). The median length of stay was longest (3 days) for adenovirus, metapneumovirus and mycoplasma infections, while children with negative aetiological results had a median length of stay of 2 days. Fever duration during admission (P
CONCLUSION. Although rapid enhanced diagnostics may not have a major influence on length of stay, these data form an integral part of enhanced sentinel surveillance systems.
