Potentially Preventable Within Stay Readmission Measure.

The potentially preventable readmission (PPR) definition for the inpatient rehabilitation facility (IRF) within-stay measure was developed concurrently with the definition used in the post-discharge measures.

The IRF within-stay measure includes all IRF discharges after the appropriate exclusions have been applied.

Denominator Exclusions: IRF Within Stay Measure Several of the exclusions listed for the IRF post-discharge measure apply to the IRF within-stay measure except for the following: Exclusion related to: patients/residents who died during the post-acute care (PAC) stay Exclusion related to patients/residents who were transferred at the end of a stay to another skilled nursing facility (SNF)/IRF/long-term care hospital (LTCH) or short-term acute care hospital Exclusion related to patients/residents who were not continuously enrolled in Part A FFS Medicare for the 12 months prior to the SNF/IRF/LTCH admission date, and at least 30 days after SNF/IRF/LTCH discharge date Exclusion related to patients/residents who did not have a short-term acute-care stay within 30 days prior to a SNF/IRF/LTCH admission date.

All measures are based on administrative claims data.
