The investigators addressed these concerns by estimating changes in a set of outcome measures at several months before and after implementation of a new EHR in 17 US hospitals; they then compared those changes with changes in the same measures in 399 control hospitals over the same regions and dates. They included only “big bang” implementations, in which all clinical functions transition to the new system on a single “go live” date; these are likely more disruptive than gradual roll-outs. The primary outcomes were changes in 30 day mortality and readmissions; …
