This life-threatening condition often leads to acute kidney injury. We aimed to determine the effectiveness of the McMahon score in predicting mortality due to rhabdomyolysis in patients affected by the earthquake. Methods: This is a retrospective observational study. In this study, the clinical and laboratory data of patients who presented to the emergency department due to the earthquake were analyzed. The McMahon score was calculated by evaluating factors such as creatine kinase, serum creatinine levels, age, and gender. Results: The study included 151 patients, of whom 74 (49.0%) were male and 77 (51.0%) were female. In the univariate model, significant (P < .05) effectiveness was observed in differentiating between patients with and without mortality for McMahon score and the risk of acute kidney injury. At a McMahon score cutoff of 6, significant effectiveness was also observed, with an area under the curve of 0.723. At this cutoff value, the sensitivity was 80.0% and the specificity was 64.5%. Conclusions: The use of the McMahon score in emergency medicine and disaster management plays a crucial role in rapid decision-making processes due to its effectiveness in predicting mortality. Key messages What is already known on this topic center dot Rhabdomyolysis, often associated with crush syndrome and acute renal failure, leads to elevated serum creatinine levels due to muscle breakdown, frequently seen in trauma and earthquake victims. What this study adds center dot The McMahon score helps predict mortality and acute kidney injury in rhabdomyolysis patients, particularly after earthquakes, by evaluating key clinical and demographic factors. How this study might affect research, practice, or policy center dot This study highlights the McMahon score's reliability in predicting mortality in rhabdomyolysis patients, potentially guiding future research on early intervention strategies and trauma management, informing clinical practices for rapid assessment and treatment.eninfo:eu-repo/semantics/closedAccessaccident and emergency medicineacute renal failuredialysistrauma managementArticle10111914549WOS:0012912787000012-s2.0-852140538243914060610.1093/postmj/qgae103Q1Q1
