Background: Chronic kidney disease (CKD) is associated with comorbidities and altered pharmacokinetics, making appropriate prescribing, and monitoring necessary to minimise drug-related problems (DRPs). Therefore, this study aimed to describe the drug-utilisation pattern in hospitalised CKD patients.
Methods: An observational study was conducted in hospitalised adult (≥18 years old) CKD patients in the UK using WHO prescribing indicators, from November 2021 to April 2022 in a large teaching hospital in England from admission until discharge. This study used STATA version 16 for analysis.
Results: The mean number of drugs per prescription was 11.1(±5), the percentage of encounters resulting in the prescription of an antibiotic was 62%, the percentage of drugs prescribed by generic name was 90%, the percentage of encounters resulting in the prescription of an injection was 94%, and the percentage of drugs prescribed from essential drugs list or formulary was 89%. The most frequent drug group prescribed Alimentary Tract and Metabolism was 22%. Longer hospital stays, admission to a renal ward, and the number of comorbidities were independently associated with polypharmacy.
Conclusion: Not all prescribing indicators evaluated in this study were in full compliance with WHO recommendations. Polypharmacy was found in most participants which might require interventions to avoid DRPs. Further research is needed to evaluate factors associated with prescribing in the CKD population and prescriber perspectives on decision-making in the context of available guidelines and patient factors.
