OBJECTIVES: To date, we have only limited evidence of the determinants of earthquake inpatient mortality-related factors. This study is among the first to explore related factors of inpatient deaths using data from multiple hospitals and multiple earthquakes.

METHODS: We included and retrospectively analyzed data on 32,976 earthquake inpatients in the West China Earthquake Patients Database. Of these, we analyzed the records of 284 patients who died during hospitalization. We collected 12 dichotomous variables with reference to previous reports: patients' age (both ≤ 15 years and ≥ 65 years), gender, prehospital treatment, intensive care unit (ICU) admission, the presence of severe traumatic brain injury (TBI), trunk injury, severe poly-trauma, crush syndrome, multiple-system organ failure (MSOF), infection, and cardiac/respiratory disease. We performed multivariate logistic regression analysis to explore independent related factors of mortality.

RESULTS: Ultimately, we identified severe TBI, MSOF, old age (≥ 65 years), ICU admission, crush syndrome, and cardiac/respiratory disease as independent mortality-related factors. Severe TBI was the greatest risk factor of inpatient death (ods ratio [OR], 31.913, 95% confidence interval [CI], 20.484-49.720), followed by MSOF (OR 30.905, 95% CI, 21.733-43.947).

CONCLUSION: To reduce earthquake inpatient mortalities, the related factors analyzed in this study should be prioritized in future inpatient earthquake response strategies.
