Parent and patient perspectives on barriers to medication adherence in adolescent transplant recipients.

The aim of this study was to identify barriers to medication adherence in adolescent transplant recipients. Eighty adolescent transplant recipient families reported in an open-ended manner about barriers to medication adherence. These responses were then coded to reflect potentially important themes associated with medication adherence. The themes derived included: forgot/distracted, poor planning/scheduling issues, physical barriers/medication issues, and voluntary resistance/attempts to be normal. Inter-rater reliability for barrier coding was very high (k = 0.91). Patients who were classified as non-adherent reported significantly more overall barriers, more forgot/distracted barriers, and more voluntary resistance/attempts to be normal barriers than those classified as adherent. Non-adherence was also found to be more likely when adolescents, as opposed to parents, were responsible for administering the medication. Further, non-adherence was more likely when taking morning rather than evening doses. These findings are explained with an emphasis on potential remedies that directly address the stated barriers.
