Number and rates of death and cardiovascular outcome events in the coverage gap period among exposed and unexposed patients in the PS-matched and hdPS-matched pooled cohorts.

PS-matched hdPS-matched

Exposed (No financial assistance in the coverage gap) N=8,054 Unexposed (Financial assistance in the coverage gap) N=8,054 Exposed (No financial assistance in the coverage gap) N=7,984 Unexposed (Financial assistance in the coverage gap) N=7,984

N (rate per 100 person-years*) unless otherwise noted
Death from any cause 123 (5) 107 (4) 123 (5) 123 (4)
Hospitalization with a primary or secondary diagnosis of*:
Myocardial infarction, stroke, or death 138 (6) 127 (5) 138 (6) 162 (6)
Myocardial infarction or stroke 51 (2) 57 (2) 51 (2) 79 (3)
Acute Coronary Syndrome (ACS)§ with revascularization 56 (2) 60 (2) 55 (2) 69 (3)
Congestive heart failure 140 (6) 168 (6) 140 (6) 169 (6)
Atrial fibrillation 109 (5) 130 (5) 110 (5) 136 (5)
*

Person-years were calculated between the date a beneficiary reached the coverage gap spending threshold and the date of first outcome, date he/she reached the end of the study year, or date he/she reached the catastrophic coverage spending threshold, whichever was earliest.

**

For specific codes, please see the Appendix.

The stroke definition includes inpatient codes for ischemic and hemorrhagic stroke and excludes transient ischemic attack.

§

The definition for acute coronary syndrome includes inpatient codes for myocardial infarction or angina.

Revascularization included any of the following procedures during the same hospital stay as the ACS diagnosis: percutaneous transluminal coronary angioplasty, coronary artery bypass grafting, placement of a stent, systemic or intracoronary thrombolysis, and angiography.
