Abstract

Objective: To evaluate the appropriateness in dosage adjustments among inpatients with renal impairment. Materials and methods: A retrospective descriptive study was conducted on patients with CrCl of < 60 mL/min admitted to at Gia Dinh People’s Hospital from January 1st to January 31st 2021. The data collected for analysis included characteristics of patients with renal impairment, appropriateness of dosage adjustments and associated factors. Drug dosage adjustment was considered appropriate if followed information from product summary characteristics. Results: A total of 4150 drug orders were prescribed for 111 patients, of which, 603 (14.5%) required dose adjustments. Approximately 37.1% (225/603) were adjusted inappropriately. Antibiotics were the most common drug class that needed adjustments (65.5%). The rates of inappropriate dose adjustments for levofloxacin, piperacillin/tazobactam and ciprofloxacin were 63.4%; 22.4% and 45.8%, respectively. Geriatrics department, renal comorbidities, and the number of drugs requiring renal dose adjustment were factors that associated with inappropriate dose adjustments. Conclusions: It is necessary to monitor and counsel healthcare professionals about renal dosage adjustments.
