TSL SCORE STRATUM^b	PRIOR TO STUDY		TARGETED DISTRIBUTION FOR STUDY	DISTRIBUTION ACHIEVED IN THE STUDY
TSL SCORE STRATUM^b	% of all adult hospitalizations	Outcome rate among patients in this risk stratum	TARGETED DISTRIBUTION FOR STUDY	% 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.
