Cancer patients are particularly at risk for being readmitted within 30 days after discharge. However, many of these readmissions are either related to elective chemotherapy or are not avoidable. In order to identify the cancer patients who might benefit from more intensive discharge interventions, we aim to identify the risk factors associated with 30‐day potentially avoidable readmission in cancer patients.
We included all consecutive discharges from the oncology division of an academic tertiary medical center in Boston between July 1, 2009 and June 30, 2010. Potentially avoidable 30‐day readmissions to the index hospital or two other hospitals within its network were then identified using a validated computerized algorithm based on administrative data (SQLape). We performed a multivariable logistic regression in which the final model included variables that were found to be significantly associated with the outcome in bivariable testing.
Among the 2,916 patient discharges during the study period, 1,086 (37.3%) were followed by a readmission within 30 days. Of these, 341 (31.4% of all readmissions, 11.7% of all discharges) were identified as being potentially avoidable. In a multivariable analysis, the following risk factors were associated with a significantly higher potentially avoidable readmission risk (Table): number of admissions in the previous 12 months, non‐elective index admission, and hematological neoplasm.
Cancer patients have a high risk of readmissions. The main risk factors associated with 30‐day potentially avoidable readmission in this population are a higher number of prior admissions, a non‐elective index admission, and a hematological neoplasm. Interventions at discharge may be prioritized to the cancer patients with these risk factors.
