Frailty can increase the risk of dying after suffering a severe injury. The Modified Frailty Index (MFI) was developed by the American College of Surgeons National Surgical Quality Improvement Program to determine the impact of frailty on outcomes. Our aim was to correlate frailty with survival following a burn injury using the 11-item and 5-item MFI. We performed a secondary analysis of the Transfusion Requirement in Burn Care Evaluation (TRIBE) study. Data including, age, gender, medical history, extent and severity of burn injury, inhalation injury and discharge disposition was collected from the TRIBE database. The 11-item MFI (MFI-11) and 5-item MFI (MFI-5) scores were calculated for all patients in the TRIBE database. The TRIBE database included 347 patients. The mean age of subjects was 43 ± 17 years. Mean total body surface area burn (TBSA) was 38 ± 18%, and 23% had inhalation injury. Multivariate logistic regression analysis determined that both MFI-5 (OR 1.86; 95% CI: 1.11-3.11; P-value .02) and MFI-11 (OR 1.83; 95% CI: 1.18-2.8; P-value .007) were independent predictors for mortality. Additionally, MFI-11 scores that are >1 were independently associated with a markedly increased risk of dying after a burn injury (OR 2.91; 95% CI: 1.1-7.7; P-value .03). The MFI can be used to identify vulnerable burn injured patients who are at high risk of dying.
