Abstract

Purpose: To assess and compare the prevalence of medication nonadherence (MNA) (implementation and persistence) to immunosuppressants and co-medications in heart transplant recipients.

Methods: MNA prevalence was assessed using the Basel Assessment of Adherence to Immunosuppressive Medications Scale (self-report) and compared using logistic regression in a 4-continent sample of 1397 heart transplant recipients from 36 heart transplant centers in 11 countries.

Findings: MNA was significantly (α = 0.05) higher to co-medications than to immunosuppressants (taking nonadherence: 23.9% vs 17.3%; odds ratio [OR] = 1.5; 95% CI, 1.30-1.73; drug holiday: 5.7% vs 1.9%; OR = 3.17; 95% CI, 2.13-4.73; dose alteration: 3.8% vs 1.6%; OR = 2.46; 95% CI, 1.49-4.06; and discontinuation: 2.6% vs 0.5%; OR = 5.15; 95% CI, 2.36-11.20).

Implications: The observed MNA necessitates adherence-enhancing interventions encompassing the entire post-heart transplant medication regimen. ClinicalTrials.gov identifier: NCT01608477.

Keywords: co-medications; cross-sectional; heart transplantation; immunosuppressants; international; medication adherence.
