RESUMO
BACKGROUND: Efforts to increase transparency and accountability of nursing homes, and thus improve quality, now include information about changes in nursing home ownership. However, little is known about how change in ownership affects nursing home quality. METHODS: We conducted a retrospective cohort study of 15,471 U.S. nursing homes between January 2016 and December 2022, identifying all changes in ownership during that period. We used logistic regression to measure the association between nursing home characteristics and the odds of a change in ownership. A difference-in-differences model with multiple time periods was used to examine the impact of a change in ownership on the Medicare Nursing Home Compare 5-star ratings. RESULTS: One in five (23%) facilities changed ownership between 2016 and 2022. Nursing homes that were urban, for-profit, part of a chain, located in the South, had >50 beds, lower occupancy, higher percentage of stays covered by Medicaid, higher percentage of residents with non-white race, or a 1-star (poor) rating were more likely to undergo a change in ownership. There was a small statistically significant decrease in 5-star ratings after a change in ownership (-0.09 points on a 5-point scale; 95% CI -0.13 to -0.04; p < 0.001), driven primarily by a decrease in staffing ratings (-0.19 points; 95% CI -0.24 to -0.14; p < 0.001), and health inspections ratings (-0.07 points; 95% CI -0.11 to -0.03; p = 0.001). This was mitigated by an increase in quality measure ratings (0.15 points; 95% CI 0.10-0.20; p < 0.001). CONCLUSION: Nursing Home Compare ratings decreased slightly after a change in facility ownership, driven by lower staffing and health inspection ratings and mitigated somewhat by higher quality measure ratings. These conflicting trends underscore the need for transparency around changes in facility ownership and a better understanding of consequences of changes in ownership that are salient to patients and families.
