“Physician order entry and decision support I believe offer the most chance of improving healthcare delivery. There are a lot of information systems with bells and whistles that don’t focus on physicians’ real needs.” – Neil R. Powe, MD, MPH, MBA, Chief of Medical Services, San Francisco General Hospital source

I previously posted about the benefits of EMR interoperability. The above quote touts Physician order entry and clinical decision support as the most likely to improve healthcare. Are these the three most promising features of an EMR or is there something they’re missing? What’s the killer feature of an EMR that will make every doctor implement an EMR whether they like it or not?
