Regression discontinuity estimates of associations between implementation of the Transitions Program and 30 day post-discharge outcomes

30 day outcome	Absolute risk reduction* (%, 95% CI)
	All admissions	Inpatient only	HEDIS regulatory definition only†
Non-elective readmission	−2.7 (−3.2 to −2.2)	−2.9 (−3.4 to −2.3)	−2.5 (−3.1 to −1.9)
Post-discharge mortality	−0.7 (−1.4 to −0.0)	−0.9 (−1.7 to −0.1)	NA†
Out-of-hospital mortality	−0.4 (−1.1 to 0.2)	−0.5 (−1.2 to 0.2)	NA†

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

Regression discontinuity design fits the estimates only near 25% risk threshold used to assign the Transitions Program intervention; hence, these local average treatment effect (LATE) estimates do not generalize to higher or lower risk levels.

^*Estimate for LATE.

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