“An important goal in the effort to achieve widespread adoption of Electronic Health Records (EHRs) is to allow patient data to flow easily from where it is housed to where it is needed. Though it is conceptually simple, such a goal is remarkably difficult to achieve.
The legacy of EHRs, which have been around for over a decade, has been mainly to replace paper note-taking with their electronic equivalent. Legibility issues go away, and finding a patient’s record in the clinic is no longer the headache it once was. Mostly, EHRs were built to be locally installed, and be the electronic equivalent of a doctor’s chart rack (the local paper “database” for patient health records).”
