To determine the impact of a telephone call reminder program provided by a campus-based medication therapy management call center on medication adherence in Medicare Advantage Part D (MAPD) beneficiaries with hypertension.MethodsThe reminder call services were offered to eligible MAPD beneficiaries, and they included a live interactive conversation with patients to assess the use of their medications. This study used a quasi-experimental design for comparing the change in medication adherence between the intervention and matched control groups. Adherence, defined by proportion of days covered (PDC), was measured using incurred medication claims 6 months before and after the adherence program was implemented. A difference-in-differences approach with propensity score matching was used.ResultsAfter propensity score matching, paired samples included 563 patients in each of the intervention and control groups. The mean PDC (standard deviation) increased significantly during postintervention period by 17.3% (33.6; P <0.001) and 13.8% (32.3; P <0.001) for the intervention and the control groups, respectively; the greater difference-in-differences increase of 3.5% (36.3) in the intervention group over the control group was statistically significant (P = 0.022). A generalized estimating equation model adjusting for covariates further confirmed that the reminder call group had a significant increase in pre-post PDC (P = 0.021), as compared with the control group.ConclusionsAntihypertensive medication adherence increased in both reminder call and control groups, but the increase was significantly higher in the intervention group. A telephonic outreach program was effective in improving antihypertensive medication adherence in MAPD beneficiaries.
