Intervention: After a 2-month run-in phase during which baseline medication adherence (via pill counts), blood pressure, and low-density lipoprotein cholesterol were measured, participants entered a 6-month intervention phase during which standardized medication education and regular follow-up by a clinical pharmacist was provided and medications were dispensed in daily, time-specific blister packs. Following the intervention phase, participants were randomized to continued pharmacy care/blister packs versus usual care (return to their original method of medication administration) for an additional 6 months.
