Perceived barriers to adherence among adolescent renal transplant candidates

Abstract:  Non‐adherence to medical regimens is a ubiquitous hindrance to quality health care among adolescent transplant recipients. Identification of potentially modifiable barriers to adherence when patients are listed for organ transplant would help with early intervention efforts to prepare adolescents for the stringent medication regimen post‐transplant. Fifty‐six adolescents listed for a kidney transplant, mean age 14.27 (s.d. = 2.2; range 11–18 yr), 73.2% male, 62.5% Caucasian participated in a semi‐structured interview, the Medical Adherence Measure, to assesses the patient’s knowledge of the prescribed regimen, reported adherence (missed and late doses), the system used to organized medications, and who holds the primary responsibility over medication management. Better knowledge of the medication regimen was associated with fewer missed doses (r = −0.48, p < 0.001). Patients who perceived more barriers had more missed (r = 0.38, p = 0.004) and late (r = 0.47, p < 0.001) doses. Patients who endorsed “just forget,” the most common barrier (56.4%), reported significantly more missed (z = −4.25, p < 0.001) and late (z = −2.2, p = 0.02) doses. Only one‐third of the transplant candidates used a pillbox to organize medications but these patients had significantly better adherence, z = −2.2, p = 0.03. With regard to responsibility over managing the regimens, adolescents missed fewer doses when their parents were in charge than when they were solely responsible, z = −2.1, p = 0.04. Interventions developed to prepare transplant candidates for a stringent post‐transplant regimen need to focus on ensuring accurate knowledge of as simple a regimen as possible. Use of an organized system such as a pillbox to establish a routine and facilitate tracking of medications is recommended with integration of reminders that may be appealing for this age group. Although individuation is developmentally normative at this age, parent involvement seems critical until the adolescent is able to manage the responsibility more independently.
