This retrospective cohort study analyzed medication adherence in 2,429 patients post-myocardial infarction using digital bottle cap data from the DAPA-MI RCT. It found that younger age, smoking, and nonworking days were linked to lower adherence, while better adherence correlated with lower time variance in medication timing and morning use. The study highlights the potential of digital monitoring in understanding adherence behaviors.
Key findings
- Younger patients (<40 years) had lower adherence (OR 0.47, 99.9% CI 0.23-0.98).
- Current smokers showed reduced adherence (OR 0.67, 99.9% CI 0.51-0.87).
- Higher adherence was associated with low 7-day average time variance (OR 1.99, 99.9% CI 1.78-2.23).
- Patients with severe angina had higher dose consistency (DCR 0.83, 99.9% CI 0.74-0.94).
Why it matters
Understanding medication adherence behaviors through objective measures can help clinicians identify patients at risk of nonadherence, enabling targeted interventions to improve outcomes in cardiovascular disease management.
