## TL;DR

This study finds that about 7% of hospitalized COVID-19 patients had chronic kidney disease, with a higher rate than some previous studies.

## Contribution

The study reports a novel prevalence rate of chronic kidney disease in hospitalized COVID-19 patients at a tertiary care center.

## Key findings

- Chronic kidney disease prevalence was 7.36% among hospitalized COVID-19 patients.
- Most patients with chronic kidney disease were male (69.77%).
- The prevalence was higher than in some similar studies.

## Abstract

Comorbidities are frequently seen in admitted COVID-19 patients most common being hypertension, diabetes, cardiovascular diseases and chronic kidney disease. Chronic kidney disease is a slowly progressive chronic illness due to the gradual loss of kidney function or structure. The available data regarding the prevalence of chronic kidney disease and COVID-19 comorbidities is still limited. The aim of this study was to find out the prevalence of chronic kidney disease among COVID-19 patients admitted to the Department of Medicine of a tertiary care centre.

A descriptive cross-sectional study was done in the Department of Medicine of a tertiary care centre. Data of medical records between 1 August 2020 to 1 December 2022 were reviewed retrospectively. The data was collected from 20 January 2023 to 20 March 2023. Ethical approval was obtained from the Institutional Review Committee (Reference number: 646/2079/80). Data on chronic kidney disease patients among COVID-19 patients were collected from the hospital records. Convenience sampling method was used. Point estimate and 95% Confidence Interval were calculated.

Among 584 COVID-19 patients admitted, the prevalence of chronic kidney disease was 43 (7.36%) (5.24-9.48, 95% Confidence Interval). A total of 30 (69.77%) were male and 13 (30.23%) were female with a mean age of 55±16.22 years.

The prevalence of chronic kidney disease among COVID-19 patients admitted in the department of Medicine of a tertiary care centre was found to be slightly higher than other studies done in similar settings.
