Aim: The purpose of this study was to examine differences in reported barriers to immunosuppressant adherence (IA) between a cohort of pediatric renal transplant recipients from the United States (US) and Canada.

Background: Adolescents and young adults (AYA) are at highest risk for poor IA, threatening their health and allograft survival. Among adult renal transplant recipients, comparisons of barriers to IA across geographic regions have shed light on country-specific variations in the determinants of health outcomes. Yet, there is little comparative data on country-specific differences in IA barriers among pediatric renal transplant recipients.

Methods: Data were collected as part of the TAKE-IT study, a large multi-center randomized controlled trial of an adherence intervention for AYA renal transplant recipients from the US and Canada. A total of 170 participants (N=111 US, N=59 Canadian) completed detailed, baseline demographic questionnaires (incl. insurance status) and the Medical Adherence Measure Medication Module.

Results: Canadians most frequently reported IA barriers were forgetfulness (56%), interference with activity (34%), and absence from home (31%). In the US, forgetfulness (27%), interference with activity (24%), and absence from home (16%), were also most common. More US respondents (35%) reported that they did not miss medications than Canadians (17%). Chi-square analyses found significant associations between insurance status and IA barriers of forgetfulness X2(3, N=169) = 14.6, p˂.01; absence from home X2(3, N=169) = 11.4, p=.01; and medication refusal X2(3, N=169) = 8.044, p=.05.

Conclusions: Pediatric renal transplant recipients in the US were less likely to report missing medications than those in Canada. In both groups forgetfulness, interference with activity, and absence from home were the most commonly reported IA barriers. Similar patterns of barriers to IA may suggest universal application of adherence interventions between these groups.
