Abstract

During the U.S. Civil War surgeons performed a vast number of surgeries. Whether surgery increased wounded soldiers' chances of survival has been debated ever since. I analyze a unique observational data set gathered by Dr. Edmund Andrews, a surgeon with the 1st Illinois Light Artillery. I use Dr. Andrews's data, model selection tools, and doubly robust estimation methods to estimate treatment effects from surgery. I find that surgery increased wounded soldiers' chances of survival by 0.09-0.16, depending on the specific model of surgical procedure.
