Many factors can contribute to early, unplanned readmissions among critical care patients. In this prospective cohort study, adult patients who were discharged directly home after an ICU admission were followed for 8 weeks post-discharge to explore the predictors of adverse events and unplanned return visits to a health care facility. Among 129 patients, there were 39 unplanned return visits. Researchers identified eight predictors of unplanned return visits including prior substance abuse, hepatitis, discharge diagnosis of sepsis, ICU length of stay exceeding 2 days, nursing workload, and leaving against medical advice.
