The TROUT Index was developed to rapidly prognosticate key adverse outcomes after injury among older adults using baseline frailty. The TROUT Index quantifies an individual's frailty risk (low, moderate, high) and outputs population-level estimates of outcomes base on baseline frailty. Disclaimer: Predicted risk should supplement, not replace, management decisions, which should be provider and hospital-specific. Please seek a doctor's advice before making any medical decisions.
