Abstract
OBJECTIVE: The objective of this study was to document the growth of postacute care and contemporaneous staffing trends in US nursing homes over the decade 2001 to 2010. DESIGN: We integrated data from all US nursing homes longitudinally to track annual changes in the levels of postacute care intensity, therapy staffing and direct-care staffing separately for freestanding and hospital-based facilities. SETTING: All Medicare/Medicaid-certified nursing homes from 2001 to 2010 based on the Online Survey Certification and Reporting System database merged with facility-level case mix measures aggregated from resident-level information from the Minimum Data Set and Medicare Part A claims. MEASUREMENTS: We created a number of aggregate case mix measures to approximate the intensity of postacute care per facility per year, including the proportion of SNF-covered person days, number of admissions per bed, and average RUG-based case mix index. We also created measures of average hours per resident day for physical and occupational therapists, PT/OT assistants, PT/OT aides, and direct-care nursing staff. RESULTS: In freestanding nursing homes, all postacute care intensity measures increased considerably each year throughout the study period. In contrast, in hospital-based facilities, all but one of these measures decreased. Similarly, therapy staffing has risen substantially in freestanding homes but declined in hospital-based facilities. Postacute care case mix acuity appeared to correlate reasonably well with therapy staffing levels in both types of facilities. CONCLUSION: There has been a marked and steady shift toward postacute care in the nursing home industry in the past decade, primarily in freestanding facilities, accompanied by increased therapy staffing.
