Medication adherence in youths with CKD: habits for success

Cyd K Eaton et al. Pediatr Nephrol. 2023 Nov.

Abstract

Background: Poor adherence habits are key contributors to nonadherence but there are few clinically feasible methods for evaluating adherence habits, particularly for youths with chronic kidney disease (CKD). This study investigated how participants' qualitative responses to three interview questions about adherence habits mapped to primary principles of habit formation and objectively measured medication adherence in youths with CKD.

Methods: Participants (ages 11-21 years) were recruited from a pediatric nephrology clinic as part of a larger study. Participants' daily objective antihypertensive medication adherence was measured with an electronic pill bottle over a 4-week baseline period. Qualitative interviews about adherence habits and routines were conducted with a subset of participants (N = 18).

Results: Clear qualitative differences emerged in how participants with high-medium adherence (80-100%) discussed adherence habits compared to participants with low adherence (0-79%). Participants with high-medium adherence discussed situational cues for taking medicine, including locations that cue adherence, step-by-step events leading up to taking medicine, and people who cue adherence. Participants with high-medium adherence regularly described taking medicine as "automatic," "second nature," and a "habit." Participants with low adherence rarely discussed these habit features nor did they explicitly acknowledge currently missing doses. Participants with low adherence tended to discuss challenges with organization and routines for taking medicine.

Conclusions: Evaluating patient responses to questions about adherence habits may uncover challenges with adherence habit formation, provide direction for habit-strengthening intervention focused on developing automatic cues for taking medication, and support adherence successes for youths with CKD.
