Abstract
BACKGROUND: This work aimed to shed light on the notorious debate over the role of an educational/cognitive/behavioral or psychological approach in the reduction of interdialytic weight gain (IDWG) in patients on chronic hemodialysis. METHODS: Searches were run from 1975 to January 2022 on Medline, PubMed, Web of Science, and the Cochrane Library. The search terms included "hemodialysis/haemodialysis" AND "adherence" AND ("fluid intake" OR "water intake") AND ("weight gain" OR "interdialytic weight gain" OR "IDWG") AND "patient-level interventions. Randomized controlled studies were eligible if they were in English, published in a peer-reviewed journal and regarded adults patients with on chronic hemodialysis for at least 6 months; compared educational/cognitive and/or counseling/behavioral or psychological interventions to no intervention on interdialytic weight gain. Outcome of interest was interdialytic weight gain. The review was registered on the International Prospective Register of Systematic Reviews in Health and Social Care (PROSPERO, ID number CRD42022332401). RESULTS: Eighteen studies (1759 patients) were included in the analysis. Compared to the untreated group, educational/cognitive and/or counseling/behavioral interventions significantly reduced interdialytic weight gain with a pooled mean difference of - 0.15 kg (95% CI - 0.26, 30-0.05; P = 0.004). On the other hand, psychological/affective interventions reduced interdialytic weight gain with a pooled mean difference of - 0.26 kg (95% CI - 0.48, - 0.04; P = 0.020). CONCLUSIONS: Educational/cognitive, counseling/behavioral or psychological/affective interventions significantly reduced the interdialytic weight gain in patients on chronic hemodialysis, although such reduction did not appear to be clinically relevant on hard outcomes.
