This study aimed at assessing the diagnostic accuracy of this investigation in a designated trauma centre. Methods： This was a retrospective study of BAT pa tients over a 6 year period seen in a trauma centre in Hong Kong. FAST findings were compared with laparotomy, ab dominal computed tomography or autopsy findings, which served as the gold standard for presence of intraperi toneal free fluids. The patients who did not have FAST or gold standard confirmatory test performed, had preexisting peritoneal fluid, died at resuscitation or had imcomplete docu mentation of FAST findings were excluded. The performance of FAST was expressed as sensitivity, specificity, predictive values （PV）, likelihood ratios （LR） and accuracy. Results： FAST was performed in 302 patients and 153 of them were included in this analysis. The sensitivity, specificity, positive PV, negative PV, positive LR, negative LR and accuracy for FAST were respectively 50.0%, 97.3%, 87.0%, 84.6%, 18.8, 0.5 and 85.0%. FAST was found to be more sensitive in less severely injured patients and more specific in more severely injured patients. Conclusion： FAST is a reliable investigation in the initial assessment of BAT patients. The diagnostic values of FAST could be affected by the severity of injury and staff training is needed to further enhance its effective use.展开更多

Methods： A retrospective analysis of prospectively collected data in the trauma registry of Queen Mary Hospital, Hong Kong from I January 2009 to 31 December 2013 was done. All adult patients aged 18 years or above, either primarily or secondarily diverted to Queen Mary Hospital according to the trauma patient diversion protocol, were recruited. Need for trauma center level of care was based on a consensus-based criterion standard published in 2014. Performance of the protocol in terms of over-diversion and under-diversion was determined. Results： A total of 209 patients were included for analysis. About 30% of the patients required trauma center level of care. The most common reason was the need for vascular, neurologic, abdominal, thoracic, pelvic, spine or limb-conserving surgery within 24 h of presentation. The over-diversion rate and under-diversion rate were 69.6% and 19.7% respectively. Conclusion： The trauma patient diversion protocol currently in use in Hong Kong is not accurate enough. Further revision and refinement is needed.展开更多
