A recent post in the Wall Street Journal Health Blog noted that a study found electronic medical records don’t improve outpatient quality. The authors of the Archives of Internal Medicine article, Electronic Health Records and Clinical Decision Support Systems, correctly points out that we should be skeptical and “doubt [the] argument that the use of EHRs is a “magic bullet” for health care quality improvement, as some advocates imply.”
This should surprise no one. Were we that naive to think that simply installing health information technology (HIT) in the medical field would generate significant improvement in outcomes? Does simply installing computers in our classrooms improve educational test scores?
Of course not.
The excellent commentary after the article makes some plausible reasons why the clinical decision support (CDS) didn’t seem to improve outcomes on 20 quality indicators. First, it isn’t clear that the CDS implemented across the various doctors’ offices and emergency rooms actually addressed the indicators studied. Second, the data studied is already dated (from the 2005 to 2007 National Ambulatory Medical Care Survey), a long time in technology terms (iPhone first debuted in 2007). The authors of the original article also point out that there is some evidence that institution specific use of CDS actually improves quality. Whether this can be scaled to the national level is the question.
