Abstract

Background Hospital readmissions are a frequent complication of community-acquired pneumonia (CAP), resulting in significant clinical and economic burdens. In Ethiopia, data on 30-day readmissions and related factors are lacking. This study aimed to determine the prevalence and factors associated with 30-day all-cause readmission after severe CAP hospitalization at the University of Gondar Comprehensive Specialized Hospital (UOGCSH). Methods A cross-sectional study was conducted From July 1, 2023, to June 30, 2024, among 177 patients with severe CAP who had been discharged alive from the UOGCSH. Patients were selected using a consecutive sampling technique, and severe CAP was defined according to the Infectious Diseases Society of America (IDSA) criteria. Multivariable binary logistic regression was used to identify factors associated with 30-day all-cause hospital readmission, and the results were reported with a 95% CI. Statistical significance was set at p < 0.05. Results The prevalence of 30-day all-cause hospital readmission was 29.9% (95% CI: 23.3 to 37.3); of those, the majority (71.7%) were readmitted within two weeks. Chronic obstructive pulmonary disease (AOR = 4.51; 95% CI: 1.19 - 17.15), fever (AOR = 3.12; 95% CI: 1.26 - 7.73), admission with ≥3 comorbidities (AOR = 2.68; 95% CI: 1.11 - 6.50), presence of ≥ 1 clinical instability factor at discharge (AOR = 2.54; 95% CI: 1.06 - 6.13), complications of severe CAP, including parapneumonic effusion (AOR = 3.13; 95%…

How strong is the evidence?

Evidence Hub reads this as a cross-sectional, done in people. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
