ABSTRACT: In 1994, the Hong Kong Special Administrative Region (HKSAR) introduced plans to implement a trauma system based on the recommendations outlined by Professor Donald Trunkey in his report to the local Hospital Authority. Five government-subsidized public hospitals were subsequently designated as trauma centers in 2003. This article reviews the initial experience in these five centers.
Prospective trauma registries from January 2004 to December 2008 were reviewed. Primary clinical outcome measures were hospital mortality. The Trauma and Injury Severity Score methodology was used for benchmarking with the Major Trauma Outcome Study (MTOS) database.
The majority (83.3%) of the 10,462 patients suffered from blunt trauma. Severe injury, defined as Injury Severity Score>15, occurred in 29.7% of patients. The leading causes of trauma were motor vehicle collisions and falls, with crude hospital mortality rates of 6.9% and 10.7%, respectively. The M-statistic was 0.95, indicating comparable case-mix with the MTOS. The worst outcome occurred in the first year. Significant improvement was seen in patients with penetrating injuries. By 2008, these patients had significantly higher survival rates than expected (Z-statistic=0.85). Although the overall mortality rates for blunt trauma were higher than expected, the difference was no longer statistically significant from the second year onward.
The case-mix of trauma patients in the HKSAR is comparable with that of the MTOS. A young trauma system relatively unburdened by dissimilar reimbursement and patient access issues may achieve significant improvement and satisfactory patient outcomes. Our findings may serve as a useful benchmark for HK and other Southeast Asian cities and trauma systems to establish local coefficients for future evaluations.

ABSTRACT: This study aims to evaluate the discordance between police reports of injury severity among road casualties and the length of hospital stay and the Injury Severity Scale (ISS) by linking information from the crash records of the Hong Kong Police with the trauma records of a regional hospital. Sensitivity and specificity analyses suggest that police injury grading diverges noticeably from the definition of a 12-h hospital stay. Police reports overestimate injury severity remarkably. The results of logistic regression indicate that age, the ISS, and the position of the victim significantly determine the likelihood of police injury misclassification. Furthermore, an optimal demarcation point of the length of hospital stay for serious injury is estimated.

ABSTRACT: To examine risk factors for injury to married women from domestic violence in Hong Kong.
Case control study.
Regional public hospital, Hong Kong.
All married women aged 18 to 60 years who attended an accident and emergency department for treatment of a domestic violence injury from January 2004 to June 2005.
Social and health characteristics of abused women and their husbands.
A total of 293 cases were compared to 313 controls. Eight predictive variables were found to be significant by univariate analysis: woman who is a new immigrant (P = 0.003), woman with no job (P = 0.019), husband with low educational level (P < 0.001), presence of extramarital affairs (P < 0.001), husband's unemployment (P < 0.001), husband's alcohol abuse (P < 0.001), husband's illicit drug abuse (P = 0.032), husband's mental illness (P < 0.001). Five factors were found to be significant in a logistic regression analysis: husband with a low educational level (nil to primary) [adjusted odds ratio = 2.78; 95% confidence interval, 1.149-6.727], husband unemployed (adjusted odds ratio = 9.031; 95% confidence interval, 5.163-15.796), presence of extramarital affairs (adjusted odds ratio = 5.218; 95% confidence interval, 2.899-9.395), husband's alcohol abuse (adjusted odds ratio = 6.089; 95% confidence interval, 3.460-10.716), husband's mental illness (adjusted odds ratio = 9.443; 95% confidence interval, 2.351-37.926).
Several significant risk factors have been identified for injury incurred during domestic violence to married women in Hong Kong. It provides information useful for developing local preventive strategies.
