“…Variables derived from the Area Resource File, Online Survey Certification and Reporting (OSCAR), and Minimum Data Set (MDS) were merged with the nursing home survey. Previous work on retention and turnover of CNAs indicates that important covariates are for-profit status, chain status, small facility size, large facility size, occupancy rate, location of facility in a metropolitan county, percent of residents with Medicaid, number of NHAs the nursing home has had in the past year, unemployment, registered nurse (RN) hours per day per resident, licensed practical nurse (LPN) hours per day per resident, CNA hours per day per resident, county nursing home beds, and county home health agencies (Banaszak-Holl & Hines, 1996; Castle & Engberg, 2005; Donoghue & Castle, 2007; Kash, Castle, Naufal, & Hawes, 2006; Kostiwa & Meeks, 2009; Probst et al, 2010; Wiener, Squillance, Anderson, & Khatutsky, 2009). Measures of staffing hours per resident per day were calculated from nursing home staffing data from OSCAR, described elsewhere (Tyler et al, 2013).…”
