Medicare requires that these providers submit FSI using: the minimum data set (MDS), administered quarterly in nursing homes and containing more than 400 items (Morris, Murphy, and Nonemaker, 1995; Hawes et al., 1997); the Outcome and Assessment Information Set (OASIS), collected during home health care visits, including roughly 80 items (Shaughnessy, Schlenker, and Hittle, 1995; Shaughnessy et al., 1997, 2002); and the Patient Assessment Instrument (PAI) for Inpatient Rehabilitation Facilities (IRF), including more than 50 items (IRF-PAI) (Centers for Medicare & Medicaid Services, 2002a, 2003b).
Since 2002, Medicare has used 385 case-mix groups generated from the IRF-PAI to pay inpatient rehabilitation facilities.
The MDS, OASIS, and IRF-PAI contain dozens of functional status items and thus offer rich insight into patients' functioning in these care settings.
Despite their differences, the MDS, OASIS, and IRF-PAI impose a standard format on assessing and documenting functional status within their respective care settings.
We used the 100 percent Medicare inpatient (Part A) files, Beneficiary Summary, Medicare Provider and Analysis Record (MedPAR), and Inpatient Rehabilitation Facility-Patient Assessment Instrument (IRF-PAI) files for 2009-2011.
Medicare beneficiaries discharged from an inpatient rehabilitation facility between January 1, 2010 and November 30, 2011 were identified in the IRF-PAI file.
The IRF-PAI lists 14 categories within the discharge to living setting variable.
Social support was a three-level variable (family/friends, paid/other, or none) based on integrating responses from two variables in the IRF-PAI file: marital status and living with others prior to admission.
