^a Analysis of AHA Annual Survey and IT Supplement data, 2014 to 2018. Models 1 and 2 are ordinary least squares linear probability models and include hospital and year fixed effects and robust standard errors clustered at the hospital level. Coefficients can be interpreted as percentage point changes in likelihood of interoperability.
