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-valuea analyzes differences in readmission rates by discharge location (within a specific risk group); P-valueb analyzes differences in readmission rates, length of stay, and discharge location among risk groups.
