AIM: Immunosuppressant medication non-adherence can result in allograft rejection and loss. The aim of this study was to investigate the prevalence of non-adherence and barriers to adherence with immunosuppressant medications, in an adult renal transplant cohort. METHODS: Kidney transplant recipients completed a self-report survey consisting of five validated questionnaires (Basel Assessment of Adherence to Immunosuppressive Medications Scale (BAASIS), Beliefs about Medicines Questionnaire, Immunosuppressant Therapy Barrier Scale, Brief-Illness Perception Questionnaire, and Multidimensional Health Locus of Control Scale), and provided sociodemographic information. Adherence was categorised according to BAASIS, with adherence barriers compared between the groups. RESULTS: One hundred and sixty-one patients in total completed the survey. Eighty-six participants (55%) were categorised as non-adherent, with 45% delaying doses, and 25% skipping doses. Non-adherent patients were more likely to forget doses (P = 0.005), and more likely to skip doses when their daily routine changed (P < 0.001) or when short of money (P = 0.03). Additionally, non-adherent patients had less self-reported understanding about their graft than adherent patients (P = 0.008). Adherence was not associated with a patient's medicine beliefs or perception of locus of control. CONCLUSION: Over half the patients self-reported non-adherence. The main modifiable barriers leading to non-adherence were forgetfulness and skipped doses. Personalised interventions focused on habit forming may improve adherence in this population.
