  • a Note that four psychiatric facilities were removed from the bivariate analyses.

  • b Analyzed as a resident-level or isolate-level variable, not as a facility-level variable.

  • c RUG is a facility-level score that reflects the average level of care required by residents, based upon residents' comorbidities, ability to perform activities of daily living, and the required amount of physical and occupational therapy. The RUG score was dichotomized into high and low values around the median.

  • d A nursing home's partner hospital was the hospital that transferred the most patients to that nursing home in a year.

  • e MDRO, multidrug-resistant organisms.
