Perceived barriers to medication adherence in pediatric and adolescent solid organ transplantation.

ABSTRACT: Comparisons of perceived barriers to adherence in pediatric and adolescent SOT have not been systematically conducted despite association between medication non-adherence and poor outcome. Fifteen centers in CTOT-C enrolled patients in a cross-sectional study. Subjects' guardians completed the PMBS and subjects over eight completed the Adolescent Scale (AMBS). Association of three identified PMBS factors and subject age was assessed. Secondary analyses assessed associations between PMBS, AMBS, and patient demographics. Three hundred sixty-eight subjects or their guardians completed PMBS or AMBS. A total of 107 subjects were 6-11 yr; 261 were ?12. Unadjusted and propensity-adjusted analyses indicated higher perceived barriers in guardians of adolescents as compared to guardians of pre-adolescents medication scheduling and frustration domains regardless of organ (p < 0.05). PMBS and AMBS comparisons revealed that guardians reported fewer ingestion issues than patients (p = 0.018), and differences appeared more pronounced within younger responders for scheduling (p = 0.025) and frustration (p = 0.019). Screening revealed guardians of older patients report increased perceived barriers to adherence independent of socioeconomic status. Guardians of adolescents reported fewer perceived barriers to ingestion/side effects than patients themselves, particularly in pre-adolescents (8-11 yr). Brief screening measures to assess perceived barriers should be further studied in adherence improvement programs.

Project description:Lack of adherence to medication is a trigger of graft rejection in solid-organ transplant (SOT) recipients.This exploratory study aimed to assess whether a biopsychosocial evaluation using the INTERMED instrument before transplantation could identify SOT recipients at risk of suboptimal post-transplantation adherence to immunosuppressant drugs. We hypothesized that complex patients (INTERMED>20) might have lower medication adherence than noncomplex patients (INTERMED?20).Each patient eligible for transplantation at the University Hospital of Lausanne, Switzerland, has to undergo a pre-transplantation psychiatric evaluation. In this context the patient was asked to participate in our study. The INTERMED was completed pre-transplantation, and adherence to immunosuppressive medication was monitored post-transplantation by electronic monitors for 12 months. The main outcome measure was the implementation and persistence to two calcineurin inhibitors, cyclosporine and tacrolimus, according to the dichotomized INTERMED score (>20 or ?20).Among the 50 SOT recipients who completed the INTERMED, 32 entered the study. The complex (N=11) and noncomplex patients (N=21) were similar in terms of age, sex and transplanted organ. Implementation was 94.2% in noncomplex patients versus 87.8% in complex patients (non-significant p-value). Five patients were lost to follow-up: one was non-persistent, and four refused electronic monitoring. Of the four patients who refused monitoring, two were complex and withdrew early, and two were noncomplex and withdrew later in the study.Patients identified as complex pre-transplant by the INTERMED tended to deviate from their immunosuppressant regimen, but the findings were not statistically significant. Larger studies are needed to evaluate this association further, as well as the appropriateness of using a nonspecific biopsychosocial instrument such as INTERMED in highly morbid patients who have complex social and psychological characteristics.
