RN staffing mix tracks acute-care use in nursing homes
A national panel study found lower hospitalization and outpatient emergency-department visit rates where RN share was higher, holding total nursing hours constant.
Researchers built a nationwide quarterly panel of 14,993 nursing homes and 399,820 facility-quarter observations from 2018Q4 through 2025Q2. The outcomes were long-stay unplanned hospitalization and outpatient emergency-department visit rates measured in rolling 12-month measurement windows refreshed quarterly. Holding total nursing HPRD constant, a 10-percentage-point higher RN share was associated with lower hospitalization and outpatient emergency-department visit rates. The team used nursing-home and quarter fixed-effects models with facility-clustered robust standard errors. Sensitivity analyses used one-quarter-lagged staffing, corresponding CMS “Adjusted Score” fields, and peak-pandemic exclusions. The study also found lower rates associated with a 0.1-HPRD increase in RN staffing. The associations remained negative in those analyses. The authors said the observational findings do not support causal inference. They said staffing composition should be considered alongside total nursing hours in quality improvement and workforce policy.
