The role of Mangled Extremity Severity Score in amputation triage in a transport health facility with catastrophic earthquake admissions.

BACKGROUND: The purpose of this study is to assess the diagnostic utility of the Mangled Extremity Severity Score (MESS) in the prediction of amputation after a major earthquake, and its utility in disaster triage. METHODS: Study results were presented from a tertiary hospital in Diyarbakir, which was affected by the earthquake but served as a transport hub for other cities in the region affected by the earthquake. MESS was calculated and its diagnostic value is analyzed in predicting amputations. MESS scores were divided into low risk, intermediate risk, and high risk groups by the researchers based on their diagnostic value analysis. RESULTS: 79 patients were included in the study. Based on the outcome of amputation or salvage, patients were divided into two groups. 24.1% (n = 19) of the patients had amputations. Both gender and mean age did not differ statistically significantly between the groups (p > 0.05). Compared with the salvage group, the amputation group had a significantly longer prehospital stay and higher rate of vascular injury and higher median MESS (p = 0.007, p < 0.001, p < 0.001; respectively). Based on MESS scores, amputation outcomes were predicted with an accuracy of 0.889 (95% CI 0.798-0.949). Those with a MESS score below 9 were considered low risk (sensitivity = 100%) whereas those with a MESS score above 12 were considered high risk (specificity = 98.33%). CONCLUSION: In transport centers, MESS may be useful for surgical triage of earthquake-induced limb crush injuries.
