OBJECTIVE. To assess the standard of hysterectomy in public hospitals in Hong Kong, so as to improve the quality of patient care and outcome.

DESIGN. Clinical audit.

SETTING. Twelve Hong Kong Hospital Authority public hospitals.

PATIENTS. All patients undergoing hysterectomy for benign gynaecological conditions during the period from 1 July 2002 to 31 December 2002 inclusive.

RESULTS. A total of 1330 patients were included for analysis: 934 (70.2%) having abdominal hysterectomies, 184 (13.8%) having laparoscopic hysterectomies, and 212 (15.9%) undergoing vaginal hysterectomies. Uterine fibroids constituted the commonest indication for abdominal (73.7%) and laparoscopic (61.4%) hysterectomies, while genital prolapse was the most common indication (96.2%) for vaginal hysterectomy. The majority of patients undergoing laparoscopic and vaginal hysterectomy (86.3% and 84.8% respectively) were given prophylactic antibiotics, in contrast to only 45.8% of those undergoing abdominal hysterectomy. In all, 85.8% of the abdominal and vaginal hysterectomies performed by trainees were supervised, while for trainees performing laparoscopic hysterectomy, all had specialists as their first assistant. The overall incidence of complications for vaginal hysterectomy was lower than that for both abdominal hysterectomy (P<0.001) and laparoscopic hysterectomy (P<0.05). Infectious morbidity was significantly higher in patients undergoing abdominal hysterectomy without prophylactic antibiotics.

CONCLUSION. The overall incidence of complications was lower for vaginal hysterectomies, as compared to both abdominal and laparoscopic hysterectomies, whereas the risk of urinary tract injury was significantly higher for laparoscopic hysterectomy. According to our audit, the level of supervision for the trainees was high. However, routine antibiotic prophylaxis should be more consistently used in the territory.
