Results from Multivariable Cox PH Regression Analyses Linking Regulatory Status and Quality of Care to Mortality and Time to First Event (Transfer or Death Whichever Occurred First)
Traditional Approach, with Time to Death as the Outcome* | Competing Risks Approach, with Time to First Event as the Outcome† | |
---|---|---|
Effect of regulatory status, [coded 1 for regulated and 2 for unregulated] controlling for | 1.08 (0.48, 2.42)‡ | 1.98 (0.97, 4.07) |
Age | 1.07 (1.03, 1.11) | 1.04 (1.00, 1.07) |
Comorbidity (a higher score implies greater comorbidity) | 1.34 (1.25, 1.45) | 1.23 (1.16, 1.30) |
Functional autonomy (SMAF score from 0 [complete autonomy] to 87 [total dependency]) | 1.02 (1.00, 1.04) | 1.02 (1.01, 1.04) |
Effect of care quality, (QUALCARE score from 1 [best possible care] to 5 [worst possible care]) controlling for | 1.74 (1.29, 2.34) | 1.77 (1.31, 2.40) |
Cognitive functioning (3MS score from 0 [worst] to 100 [best]) | 0.99 (0.98, 1.00) | 0.99 (0.99, 1.00) |
Subjects censored at the time of transfer when applicable.
Censoring limited to subjects who were still living in the same facility at follow-up.
Values are adjusted hazard ratios, with 95% confidence intervals in parentheses.
