Implementation of targeted deprescribing of potentially inappropriate medications in patients on hemodialysis.

PURPOSE: Patients on hemodialysis have a high risk of medication-related problems. Studies using deprescribing algorithms to reduce the number of inappropriate medications in this population have been published, but none have used a patient-partnership approach. Our study evaluated the impact of a similar intervention with a patient-partnership approach. METHODS: The objective was to describe the implementation of a pharmacist-led intervention with a patient-partnership approach using deprescribing algorithms and its impact on the reduction of inappropriate medications in patients on hemodialysis. Eight algorithms were developed by pharmacists and nephrologists to assess the appropriateness of medications. Pharmacists identified patients taking targeted medications. Following patient enrollment, pharmacists assessed medications with patients and applied the algorithms. With patient consent, deprescription was suggested to nephrologists if applicable. Specific data on each targeted medication were collected at 4 and 16 weeks. Descriptive statistics were used to examine the effects of the deprescribing intervention. RESULTS: Of 270 patients, 256 were taking at least one targeted medication. Of the 122 patients taking at least one targeted medication who were approached to participate, 66 were included in the study. At enrollment, these patients were taking 252 targeted medications, of which 59 (23.4%) were determined to be inappropriate. Deprescription was initiated for 35 of these 59 medications (59.3%). At 4 weeks, 33 of the 59 medications (55.9%) were still deprescribed, while, at 16 weeks, 27 of the 59 medications (45.8%) were still deprescribed. Proton pump inhibitors and benzodiazepines or Z-drugs were the most common inappropriate medications, and allopurinol was the most deprescribed medication. CONCLUSION: A pharmacist-led intervention with a patient-partnership approach and using deprescribing algorithms reduced the number of inappropriate medications in patients on hemodialysis.

Issues with deprescribing in haemodialysis: a qualitative study of patient and provider experiences.

RATIONALE, AIMS AND OBJECTIVES: Patients undergoing haemodialysis receive on average 10-17 medications, which increase the risk of falls, adverse drug reactions and hospitalizations. Supervised discontinuation of potentially inappropriate medications may lower these risks. Although many calls have been made for deprescribing in the haemodialysis setting, little is known about how patients and providers in this setting experience it. The aim of this study is to explore patient and provider experiences and perceptions of one of the rare deprescribing intervention in haemodialysis. METHODS: Ten semi-structured interviews were held with patients, and a focus group was done with dialysis clinic team members at a Montreal area health network's haemodialysis clinic after the implementation of a standardized deprescribing intervention using the patient-as-partner approach. The interviews and focus group were recorded, and verbatims were coded to determine emerging themes. Grounded theory was used for interview guide design and data analysis. RESULTS: The three emerging themes were (1) ambivalence towards medication creating a favourable context for deprescribing, (2) the empowering elements of the deprescribing process and (3) the uncertain future of deprescribing in the clinics even though the intervention was considered successful. CONCLUSION: Haemodialysis patients and providers viewed deprescribing favourably, believed the intervention was valuable, and offered suggestions for long term implementation while expressing concerns about feasibility. Notwithstanding the underlying uncertainties, a structured and integrated approach in routine practice involving all members of the care team may facilitate the continuity of deprescribing as an intervention in the setting of a haemodialysis clinic.
