Association of Discharge Disposition with Outcomes

Understanding the relationships between discharge disposition, readmissions, and cost of care is an important strategy for Accountable Care Organizations (ACOs) with aspirations to achieve shared savings. The purpose of this retrospective cohort study is to examine whether there is an association between the discharge dispositions of home with home health (HH) compared to skilled nursing facility (SNF) and the readmission rate and cost of care for Medicare ACO patients discharged from the hospital. The authors studied the variables associated with readmission rates and cost of care, including discharge disposition and risk score for 1151 patients attributed to an ACO. In multivariate logistic regression analysis, variables associated with increased risk for 30-day readmission were the Centers for Medicare & Medicaid Services Hierarchical Condition Category risk score and the discharge setting. Discharges to SNF were almost 5 times more likely to be readmitted to the hospital at 30 days compared to patients discharged to the HH setting. The cost of care is lower for the HH discharge disposition, with an $8678 per patient difference between the cost of care for patients discharged to HH and SNF levels of care. Findings from this study suggest that employing a transitional care planning approach that prioritizes discharging patients to the least restrictive next site of care, shifting patients from SNF disposition to HH as appropriate, is an effective strategy to improve readmission rates and cost of care.
