Medication Adherence in Hypertension
- Cluster randomised controlled trial
- pragmatic
- 2-arm
- cluster randomized
- 10 primary care sites
Authors' conclusion
In this pragmatic trial, an intervention that combined team-based primary care with automated identification of patients with antihypertensive medication nonadherence did not lead to improvements in adherence or blood pressure.
Study context
- Population
- Adults with uncontrolled hypertension and low medication adherence (proportion of days covered (PDC) <80%), 10 primary care sites in New York, 2022–2024
- Participants
- 1,726 adults
- Comparison
- Multicomponent adherence intervention vs usual care
- Primary endpoint
- Change in proportion of days covered (PDC) from baseline
- Follow-up
- 12 months
Primary result
Change in PDC
Adjusted difference
−0.15 percentage point
95% CI −4.06 to 3.76
By group
Intervention vs Usual care
adjusted difference −0.15 percentage point (95% CI −4.06 to 3.76)
