BackgroundThe Hong Kong Special Administrative Region (HKSAR) of the People's Republic of China (PRC) has seen significant changes in its trauma service over the last ten years including the implementation of a regional trauma system. The author's institution is one of the five trauma centres designated in 2003. This article reports our initial clinical experience.MethodsA prospective single-centre trauma registry from January 2004 to December 2008 was reviewed. The primary clinical outcome measure was hospital mortality. The Trauma and Injury Severity Score (TRISS) methodology was used for bench-marking with the North America Major Trauma Outcome Study (MTOS) database.ResultsThere were 1451 patients. The majority (83.9%) suffered from blunt injury. The overall mortality rate was 7.8%. Severe injury, defined as the Injury Severity Score > 15, occurred in 22.5% of patients, and was associated with a mortality rate of 31.6%. A trend of progressive improvement was noted. The M-statistic was 0.99, indicating comparable case-mix with the MTOS. The Z- and W-statistics of each individual year revealed fewer, but not significantly so, number of survivors than expected.ConclusionsTrauma centre designation was feasible in the HKSAR and was associated with a gradual improvement in patient care. Trauma system implementation may be considered in regions equipped with the necessary socio-economic and organizational set-up.
