Abstract

Introduction

This study aimed to investigate the severity of disease and length of hospital stay for COVID-19 patients admitted to a hospital in Southeastern Iran.

Method

This cross-sectional study was conducted in Kerman, Iran. Data were collected from patients who visited Afzalipour Hospital in Kerman more than twice during the COVID-19 epidemic from the end of February 2020 to March 21, 2021. We conducted two key analyses: 1. Mixed effect logistic regression was used to check the relationship between the variables and COVID-19 severity. 2. Mixed effect linear regression was used to check the relationship between the variables and the length of stay in the hospital.

Results and Discussion

The findings indicated that the most important risk factors for the severity of COVID-19 were heart diseases (OR=1.67,95% CI:1.20-2.30), increasing age (OR=2.23 for age >54, 95% CI:1.70-2.90), male gender (OR=1.47,95% CI:1.10-1.96), respiratory diseases other than asthma, and frequency of admission (OR=1.60,95% CI:1.20-2.15). All patients who underwent readmission experienced a shorter duration of hospitalization during their subsequent admission (OR=0.94,95% CI:0.91, 0.96) and had a higher mortality rate (30% within 14 days, 26.6% between 14-90 days). Patients readmitted at intervals of 14-90 days and greater than 90 days exhibited lower disease severity compared to those readmitted within the 0-14 day period.

Conclusion

Examining readmissions, the severity of COVID-19, and the length of hospital stay in affected patients are important factors for planning and allocating resources for COVID-19 management and treatment. These factors can help policymakers develop effective clinical guidelines for hospitalization or outpatient treatment of COVID-19 patients and contribute to reducing the burden of disease in the community.
