Thirty-day hospital readmission rate, reasons, and risk factors after acute inpatient cancer rehabilitation.

OBJECTIVES To evaluate the 30-day hospital readmission rate, reasons, and risk factors for patients with cancer who were discharged to home setting after acute inpatient rehabilitation. DESIGN, SETTING, AND PARTICIPANTS This was a secondary retrospective analysis of participants in a completed prospective survey study that assessed the continuity of care and functional safety concerns upon discharge and 30 days after discharge in adults. Patients were enrolled from September 5, 2018, to February 7, 2020, at a large academic quaternary cancer center with National Cancer Institute Comprehensive Cancer Center designation. MAIN OUTCOMES AND MEASURES Thirty-day hospital readmission rate, descriptive summary of reasons for readmissions, and statistical analyses of risk factors related to readmission. RESULTS Fifty-five (21%) of the 257 patients were readmitted to hospital within 30 days of discharge from acute inpatient rehabilitation. The reasons for readmissions were infection (20, 7.8%), neoplasm (9, 3.5%), neurological (7, 2.7%), gastrointestinal disorder (6, 2.3%), renal failure (3, 1.1%), acute coronary syndrome (3, 1.1%), heart failure (1, 0.4%), fracture (1, 0.4%), hematuria (1, 0.4%), wound (1, 0.4%), nephrolithiasis (1, 0.4%), hypervolemia (1, 0.4%), and pain (1, 0.4%). Multivariate logistic regression modeling indicated that having a lower locomotion score (OR = 1.29; 95% CI, 1.07-1.56; p = 0.007) at discharge, having an increased number of medications (OR = 1.12; 95% CI, 1.01-1.25; p = 0.028) at discharge, and having a lower hemoglobin at discharge (OR = 1.31; 95% CI, 1.03-1.66; p = 0.031) were independently associated with 30-day readmission. CONCLUSION AND RELEVANCE Among adult patients with cancer discharged to home setting after acute inpatient rehabilitation, the 30-day readmission rate of 21% was higher than that reported for other rehabilitation populations but within the range reported for patients with cancer who did not undergo acute inpatient rehabilitation.
