Interoperability Demands a Single National Patient Identifier
Guest post by Mark Summers, healthcare expert, PA Consulting Group.
At HIMSS this year, multiple speakers laid out visions for a future where parents could consult with a pediatrician via a telemedicine encounter during the middle of the night, take their children to receive immunization shots at a retail clinic, and have all of this information aggregated in their primary care provider’s record so that providing an up to date immunization record at the start of the next school year is as simple as logging into the PCP’s patient portal and printing out the immunization record. In short, multiple speakers presented visions of a truly interoperable future where patient information is exchanged seamlessly between providers, healthcare applications on smartphones, and insurers.
While initiatives such as the CommonWell Health Alliance, Epic’s Care Everywhere, and regional health information exchanges attempt to address the interoperability challenge, these fall short of fully supporting the future vision described above. Today’s solutions do not address smartphone applications and still require manual intervention to ensure that suggested record matches truly belong to the same patient before the records are linked. This process is costly but manageable in an environment where a low volume of patient records are matched between large provider organizations. In a future world where patient data is available from a multitude of websites, smartphone applications and traditional healthcare organizations, it would be cost prohibitive to manually review and verify all potential record matches.
Of course, one solution to this dilemma would be to improve patient matching algorithms and no longer require manual review of records before they are linked. However, for this to be possible, a standard set of data attributes would need to be captured by any application that would use or generate patient data. In a 2014 industry report to the Office of the National Coordinator for Health Information Technology, first name, last name, middle name, suffix, date of birth, current address, historical address, current phone number, historical phone number, and gender were identified as data attributes that should be standardized. Many of the suggestions in this report were incorporated into the Shared Nationwide Interoperability Roadmap that the ONC released in January 2015.
