Trends in Postacute Care and Staffing in US Nursing Homes, 2001–2010

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.
