Inappropriate prescribing in patients with kidney disease: A rapid review of prevalence, associated clinical outcomes and impact of interventions

Abstract

AbstractBackgroundThe prevalence of patients with chronic kidney disease (CKD) and polypharmacy is increasing and has amplified the importance of examining inappropriate prescribing (IP) in CKD. This review focuses on the latest research regarding the prevalence of IP in CKD and the related adverse clinical effects and explores new interventions against IP.MethodA literature search was performed using PubMed, EMBASE and the Cochrane Library searching articles published between June 2016 and March 2022.ResultsTwenty‐seven studies were included. An IP prevalence of 12.6% to 96% and 0.3% to 66% was reported in hospital and outpatient settings, respectively. In nonhospital settings, the prevalence of IP varied between 3.9% and 60%. IP was associated with higher risk of hospitalisation (HR 1.46, 95% CI 1.17–1.81), higher bleeding rate (HR 2.34, 95% CI 1.32 to 3.37) and higher risk of all‐cause mortality (OR 1.07, 95% CI 1.02 to 1.13). Three studies reported the impact of interventions on IP.ConclusionThis review highlights widespread IP in CKD patients across healthcare settings, with varying prevalence rates. IP is substantially linked to adverse outcomes in patients. While limited interventions show promise, urgent research is needed to develop effective strategies addressing IP and improving CKD patient care.
