Comparative analysis of Medicare discharges following an acute inpatient hospitalization under MS-DRG 207

The purpose of this study is to conduct a comparative analysis of the Medicare patients discharged to a long-term (acute) care hospitals (LTCH), skilled nursing facility (SNF) or inpatient rehabilitation facility (IRF) following an acute inpatient hospitalization under Medicare-severity diagnosis-related group (MS-DRG) 207. The likelihood of discharge by provider type was also examined to determine criteria informing patient discharge to a LTCH, SNF or IRF for treatment.

Retrospective cohort study, based on secondary data analysis, utilizing Medicare Provider Analysis and Review (MedPAR) File data collected by Centers for Medicare & Medicaid Services for fiscal year 2011, October 1, 2010, through September 30, 2011.

Numerous analyses were conducted upon those patients discharged to a LTCH, SNF or IRF following an acute inpatient hospitalization under MS-DRG 207. Concerning those patients discharged to LTCHs, patients were not significantly older, did not have the highest length of stay and had comparable diagnoses and diagnosis counts to those discharged to SNFs or IRFs. However, costs were significantly higher among discharges to LTCHs. Multinomial logistic regression analyses also indicated numerous associations between certain variables and discharge location.

With the aging of the US population and increasing costs of rendering services, both the Medicare population and Medicare expenditures, already at their highest levels in the history of the program, are projected to rise going forward (The Boards of Trustees, 2012). As such, recent research has focused on Part A hospitals/facilities and the variations in costs submitted and payments received for treatment/services provided. This study aims to address whether patients discharged to LTCHs, which receive higher payment(s) as a result of serving a higher proportion of medically complex beneficiaries, are more medically complex than those discharged to SNFs/IRFs.
