ARTICLE HIGHLIGHTS
Research background
Factors that are associated with the short-term rehospitalization have been investigated previously in numerous studies. However, the majority of these studies have not produced any conclusive results because of their smaller sample sizes, differences in the definition of pneumonia, joint pooling of the in-hospital and post-discharge deaths and lower generalizability.
Research motivation
To the best of our knowledge, there has been no systematic effort to pool data on the risk factors for hospital readmissions in patients with pneumonia.
Research objectives
To pool data from individual studies to identify risk factors for hospital readmissions in patients with pneumonia.
Research methods
Systematic search was conducted in PubMed Central, EMBASE, MEDLINE, Cochrane library, ScienceDirect and Google Scholar databases, and search engines from inception until July 2021.
Research results
In total, 17 studies with over 3 million participants were included. Majority of the studies had good to satisfactory quality as per Newcastle Ottawa scale. Male gender, cancer, heart failure, chronic respiratory disease, chronic kidney disease and diabetes mellitus had statistically significant association with the hospital readmission rate among pneumonia patients.
Research conclusions
Male gender and specific chronic comorbid conditions were found to be significant risk factors for hospital readmission among pneumonia patients. These results may allow clinicians and policymakers to develop better intervention strategies for the patients.
Research perspectives
More longitudinal studies are needed to identify accurate and reliable effect estimates and make evidence-based recommendation for developing potential interventions in hospital setting.
