Variation in 30-Day Readmission Rates Among Medically Complex Patients at Inpatient Rehabilitation Facilities and Contributing Factors

This study shows significant variation in readmission rates for medically complex patients across IRFs. However, nearly half (41.4%) of this variation was attributed to 9 patient and facility characteristics, suggesting the need for risk adjustment if readmission rates are to be used as a quality indicator for IRFs.
