EMR vs. EHR
By Steve Blumenthal, JD
HIStalk has asked me to explain the difference between an EMR (electronic medical record) and an EHR (electronic health record). Clearly, HIStalk needs to get out more. But I’m a nerdy lawyer and analyzing defined terms ranks up there with reading blogs about who’s being cast in the “Star Wars” reboot.
Let’s start with the source of most healthcare IT terminology, the feds—specifically, ONC. ONC’s website (healthIT.gov) says that an EMR is “a digital version of a paper chart that contains all of a patient’s medical history from one practice.” On the other hand, an EHR is “a digital version of a patient’s paper chart.” So, clearly an EMR and EHR are differ…. Wait a sec. Is it me, or do those definitions look remarkably similar?
I think I’ve figured it out. An EMR and EHR are both a digital version of a patient’s paper chart, but an EMR only has one practice’s patient chart. So, if I never see a physician other than my internist at Vanderbilt, Vandy’s electronic record system is an EMR with respect to me. However, my daughter has seen two doctors in different practices within Vandy’s health system, so Vandy’s electronic record system would be an EHR (not an EMR) with respect to her. No, that can’t be right.
Wait, ONC has more to say. An EHR is “more than just a computerized version of a paper chart in a provider’s office.” Whew, that clears up everything. An EHR is more than an EMR. Now I can go home and finally hang the curtains in the guest bedroom.
On second thought, that didn’t clear up anything. The curtains will just have to wait another year.
“EHR systems are built to share information with other health care providers and organizations—such as laboratories, specialists, medical imaging facilities, pharmacies, emergency facilities, and school and workplace clinics—so they contain information from all clinicians involved in a patient’s care.” I think we’ve found something. “Built to share information” is the key. I feel an analogy coming on.
