Chronic Kidney Disease (CKD) - A Brand Ambassador/Alarming Bell for Potentially Inappropriate Medication in Elderly Inpatients.

Abstract

Background: Since the past decade, prevalence of Potentially Inappropriate Medication (PIM) among elderly inpatients has increased drastically. However, limited data is available on PIM indicators and PIMs use among the elderly in patients suffering from Chronic Kidney Disease (CKD).

Objective: The objective of this study is to determine the prevalence of PIMs in elderly hospitalized patients with CKD.

Methods: A cross-sectional study was carried out on 102 patients in a tertiary care hospital. PIMs were identified using Beers criteria 2019. Chi-square test was used to identify the association between variables and PIMs use.

Results: PIMs, as assessed according to AGS updated Beers criteria 2019 was found to be in more than 68.6% of patients of median age 65 years and 3 diagnoses and 7 days median length of stay. Most of the patients (47.1%) had ≥4 diagnosis. The most common comorbidities in patient were diabetes mellitus (n=54) and hypertension (n=55). Most of the subjects (66.7%) were on polypharmacy (5-9 medications/day) and 25.5% were on a higher level of polypharmacy (>10 medicines/day). Approximately 90% of the patients were having very low CrCl < 21ml/min (calculated with the help of Cockcroft- Gault formula). A significant association between PIM use and an increased number of diagnoses, polypharmacy or high-level polypharmacy, was observed.

Conclusion: The prevalence of PIMs in elderly inpatients suffering from CKD is quite high. The study clearly indicates negligence/ lack of awareness amongst physicians leading to increase in PIM use. Authors propose that the CKD patients should attract special attention of physician and should be treated as brand ambassadors/alarming bell for PIM use.
