Performance Improvement 2011-2012. For Medicare Post-Acute Care Episodes, How Do Definitions Differ Based on Alternative Starting Points and How Do Payments and Service Mix Differ for Longitudinal and Cross-Sectional Samples?


Researchers expanded the beneficiary level episode file developed previously to reflect a longitudinal and cross-sectional analysis of three years of beneficiary level episodes. The current 5% Medicare claims sample was expanded to 30% and 100% for Medicare long-term care hospital and inpatient rehabilitation facility users. The analysis examined hospital initiated and community entrant post-acute care use episodes and bundled payments. The larger sample size will provide insight to differences in payments by geographic area.

The inclusion or exclusion of readmissions and subsequent post-acute care use has a significant impact on total episode length of stay and payments. These analyses demonstrate the shorter term, higher cost nature of service use for beneficiaries initiating a post-acute care episode with an acute hospitalization compared with the longer term, relatively lower cost service use of those entering post-acute care directly from the community. The results of the geographic analysis highlight that provider supply and geography are significant drivers of post acute care utilization and spending.
