Observational study examines risk factors for readmission in US COVID-19 patients

An observational study examined risk factors for readmission in hospitalized COVID-19 patients in the United States who were discharged and subsequently readmitted to the same hospital. The specific intervention or exposure, comparator, and primary outcome were not reported. The sample size and follow-up duration were also not reported.

The main results for the outcome of risk factors for readmission after discharge from an initial COVID-19 hospitalization were not reported. No effect sizes, absolute numbers, or statistical measures were provided. The direction of any associations was not specified.

Safety and tolerability data, including adverse events and discontinuations, were not reported. Key limitations of the study were not detailed. The funding sources and potential conflicts of interest were not reported. The practice relevance of these unreported findings is unclear and should not be used to guide clinical decisions.
