| TSL SCORE STRATUMb | PRIOR TO STUDY | TARGETED DISTRIBUTION FOR STUDY | DISTRIBUTION ACHIEVED IN THE STUDY | ||
|---|---|---|---|---|---|
| % of all adult hospitalizations | Outcome rate among patients in this risk stratum | % of all interviewed hospitalized patients | Outcome rate among patients in this risk stratum | ||
| < 15.0% | 72% | ~ 6% | 36% | 68.3% | 7.5% |
| 15.0–24.9% | 16% | ~ 18% | 24% | 17.2% | 22.5% |
| 25.0–44.9% | 8% | ~ 35% | 23% | 10.9% | 30.9% |
| ≥ 45% | 4% | ~ 50% | 16% | 3.6% | 33.9% |
aTable shows the distribution of patients in various risk strata prior to the study, the distribution we attempted to achieve, and the distribution we actually achieved.
bTSL = Transition Support Level score. The TSL is the percent risk for the study composite outcome (non-elective rehospitalization or death within 30 days of discharge). In this health system, patients with a score of ≥ 25% are automatically enrolled in the program’s follow-up protocols; patients with a score of ≥ 45% receive more intensive follow-up. See text and Escobar et al. [17] for details on this score.
