Difference-in-differences estimates of associations between implementation of the Transitions Program and 30 day post-discharge outcomes by cohort

30 day outcome	Adjusted odds ratio (95% CI)
	All admissions	Inpatient only	HEDIS regulatory definition only	High risk only*
Non-elective readmission	0.91 (0.89 to 0.93)	0.89 (0.87 to 0.91)	0.90 (0.87 to 0.92)	0.97 (0.89 to 1.06)
Post-discharge mortality	1.00 (0.95 to 1.04)	0.99 (0.95 to 1.04)	NA†	0.96 (0.88 to 1.05)
Out-of-hospital mortality	1.02 (0.97 to 1.06)	1.01 (0.96 to 1.06)	NA†	1.00 (0.91 to 1.10)

HEDIS=Healthcare Effectiveness Data and Information Set; NA=not applicable.

^*Patients with ≥45% predicted risk of composite outcome.

^†Excludes patients with <30 days of follow-up, and hence also excludes patients who died in this period.
