This table presents the results from Eq. (1). The dependent variable in all columns is the probability of having a surgical complication and each regression is estimated using OLS. Controls for month, patient age, gender, Charlson comorbidity score, indicators for 17 chronic conditions, and patient HRR fixed effects are included but not reported. Robust standard errors clustered at the Hospital Service Area level are in parentheses.
