Research published in the journal Health Services Research found a small but measurable increase of quality in treatment of inpatients with acute myocardial infarction, heart failure, and pneumonia at hospitals transitioning to EHRs in line with Stage 1 Meaningful Use requirements. But facilities saw a decrease of 0.9 to 1 percentage point for those conditions when moving beyond the 2011 requirements for Stage 1. The changes are more noticeable at hospitals with baseline quality scores in the lowest quartile.
