Results were tabulated based on the local area defined as a 70-minute driving time radius. Driving time, rural/urban area characteristics, per capita number of Medicare-certified hospice programs, and per capita number of hospice employees were defined the same as in the Materials and Methods section.
Control variables in the model include patient age, race, comorbidities, marital status, census tract median household income and education level, residence SEER area, and diagnosis year.
Model 1 includes rural/urban characteristics plus control variables.
Significance level at 0.05 level.
CI, confidence interval; OR, odds ratio; SEER, Surveillance Epidemiology End-Results.
