  • Title: Breaking the adherence barriers: Strategies to improve treatment adherence in dialysis patients.
    Author: Murali KM, Lonergan M.
    Journal: Semin Dial; 2020 Nov; 33(6):475-485. PubMed ID: 33034402.
    Abstract:
    Nonadherence to therapy (dietary/fluid restrictions, medications, and dialysis treatment), is common in patients with end-stage kidney disease (ESKD) undergoing dialysis. It is associated with a higher risk of mortality and adverse outcomes. Clinical trials evaluating adherence improvement interventions have largely addressed patient-related factors by employing educational/cognitive, counselling/behavioral, psychological strategies, or combinations thereof. A major barrier to progress in addressing ESKD-related adherence is the difficulty in comparing these trials due to the highly diverse nature of interventions and adherence outcomes. Surrogate outcomes like changes in inter-dialysis weight gain or phosphate levels are frequently used without adjusting for confounders, with the potential for biased efficacy estimates. A majority of trials reported improvement in some adherence measures, but some of the same studies showed no improvement in other adherence markers, questioning the validity of outcome measurement. Among the interventions, cognitive/behavioral strategies, combination strategies, and individually delivered interventions may have some advantages. Relapse of nonadherence, which is common on follow-up, should be managed to sustain long-term adherence. Technology-based interventions hold great future potential for addressing ESKD nonadherence. Streamlining intervention strategies and standardizing outcome measures in future clinical trials will provide reliable guidance to manage nonadherence effectively, which may improve clinical outcomes in dialysis patients.
