Measuring trauma outcomes in India: An analysis based on TRISS methodology in a Mumbai university hospital

Background: In this prospective study, the TRISS methodology is used to compare trauma care at a university hospital (Lokmanya Tilak Municipal General (LTMG) Hospital) in Mumbai, India, with the standards reported in the Major Trauma Outcome Study (MTOS). Methods: Between 1 August 2001 and 31 May 2002, 1074 severely injured patients were included in the study. Survival analysis was completed for 98.3% of the patients. Results: The majority of the patients were men (84%) and the average age was 31 years. 90.4% were blunt injuries, with road traffic crashes (39.2%) being the most common cause. The predicted mortality was 10.89% and the observed mortality was 21.26%. The mean Revised Trauma Score (RTS) was 6.61±1.65 and the mean Injury Severity Score (ISS) was 16.7±10.67. The average probability of survival ( P s) was 89.14. The M and Z statistics were 0.84 and −14.1593, respectively. Conclusion: The injured in India were found to be older, the injuries more severe and with poorer outcomes, than in the MTOS study.
