Each cell reports two-stage least squares (2SLS) coefficient estimates for a separate regression. Quality measures have been demeaned and standardized by 2 standard deviations so they can be interpreted like binary (low-to-high) indicators. The underlying mean and standard deviation of each quality measure are provided in the first column to facilitate interpretation on the original scale. Outcome means: 30-day readmission = 15.0%; 30-day mortality = 17.0%; 365-day mortality = 37.2%. Sample sizes: 546,700 (30-day outcomes), 451,503 (1-year Mortality). All models include patient demographic and ambulance controls as listed in table 1, as well as the diagnosis controls as listed in table A2. Models also include postal code–patient origin fixed effects. Standard errors, clustered at health service area level, are reported in parentheses.
