The modern practice of medicine relies on communication. Making sure the right people have access to the right information can save lives. After the initial learning curve, electronic medical record (EMR) systems have been shown to save time, from more efficient administrative processes for staff to faster turnover for lab results updates, all of which can contribute to faster diagnoses.
Interoperability between systems also reduces the number of steps and intermediaries required to contact other EMR users or update patient records. All of this makes for improved communication between patients, clinics, hospitals, labs, and pharmacies.
