Table 2. Average Positive Score (i.e. HCAHPS composite score) Multivariate Regression by County & Hospital Demographics.

A multivariate linear regression model of statistically significant dimensions of patient satisfaction as determined by Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) scores is provided below. The dependent variable is the composite of Average Patient Satisfaction scores by hospital (3192 hospitals). Predictors (independent variables) were collected from U.S. census data for counties or county equivalents. All of the listed predictors (1^st column) are statistically significant. They are placed in order of partial regression coefficient contribution to the model from most positive to most negative contribution. B = unstandardized beta coefficient, SE = standard error, β = standardized beta (partial coefficient), t = t statistic, p= statistical significance. Adjusted R Square (last row) is used to signify the goodness of fit.
