Abstract

Aims: To examine patterns of adherence to oral hypoglycemic agents among primary care patients with type 2 diabetes mellitus and to assess whether these patterns were associated with baseline intervention allocation, sociodemographic characteristics, and clinical indicators.

Methods: Adherence patterns were examined by Medication Event Monitoring System (MEMS) caps at baseline and 12 weeks. Participants (n = 72) were randomly allocated to a Patient Prioritized Planning (PPP) intervention or a control group. The PPP intervention employed a card-sort task to identify health-related priorities that included social determinants of health to address medication nonadherence. Next, a problem-solving process was used to address unmet needs involving referral to resources. Multinomial logistic regression examined patterns of adherence in relation to baseline intervention allocation, sociodemographic characteristics, and clinical indicators.

Results: Three patterns of adherence were found: adherent, increasing adherence, and nonadherent. Participants assigned to the PPP intervention were significantly more likely to have a pattern of improving adherence (Adjusted Odds Ratio (AOR)= 11.28, 95% confidence interval (CI)= 1.78, 71.60) and adherence (AOR=4.68, 95% CI=1.15, 19.02) than participants assigned to the control group.

Conclusion: Primary care PPP interventions incorporating social determinants may be effective in fostering and improving patient adherence.
