Predicting Discharge Location among Low-Energy Hip Fracture Patients Using the Score for Trauma Triage in the Geriatric and Middle-Aged (STTGMA)

Table 5

Length of stay and readmission rate for minimal-, low-, moderate-, and high-risk cohorts stratified by discharge location. Percentages reflect proportion of each respective risk cohort readmitted. P-value analyzes differences in readmission rates by discharge location (within a specific risk group); P-value analyzes differences in readmission rates, length of stay, and discharge location among risk groups.
