Each column represents a different regression model. Columns labeled AHA present models with hospital health IT derived from AHA IT data, and columns labeled HIMSS present models with hospital EHR use derived from HIMSS data. The dependent variable for these models represents Medicare expenditures averaged over our sample beneficiaries in each HRR. Select covariate results are reported in Table 3. Standard errors, adjusted for clustering by HRR, are presented in parentheses.
***p < .01, **p < .05, *p < .10.
