Note:
Sensitivity analysis: Residents’ 90-day assessment was identified as the assessment (quarterly/annual/SCSA) closest to 90 days after admission within a +/−14-day window.
Unadjusted odds ratios: Logistic regression model estimated through generalized estimation equation, adjusting for clustering of residents in the same nursing home and clustering of nursing homes in the same state. The model did not adjust for other covariates.
Adjusted odds ratios: Logistic regression model estimated through generalized estimation equation, adjusting for clustering of residents in the same nursing home and clustering of nursing homes in the same state, and controlling for residents’ demographic variables (age group, gender, race/ethnicity, marital status), health characteristics (BMI, comorbidities, number of comorbidities, physical functioning, cognitive impairment, any presence of pain), nursing home facility characteristics (ownership, size in quartiles, occupancy rate in quartiles), and geographic characteristics (region and urbanicity).
P-value for Type III test of overall association between ordinal star ratings and depression diagnosis.
P-value for linear trend for star ratings by entering the ratings as a continuous variable into the model.
