MyChart is the EHR product, developed by US based Epic Systems with The Palo Alto Medical Foundation (PAMF). The functionality requirements for a PHR were integrated with their EHR. PAMF became the first customer of MyChart, which was implemented at the end of 2000. Since then, over 90,000 patients have used PAMFOnline. Across the US, 2.4 million patients are using MyChart. MyChart enables the patients to view their diagnoses, active medications, allergies, health maintenance schedules, immunisations, test results (including graphical display), radiology results, appointments, and demographics.
In many cases, relevant health educational resources are automatically linked to key terms or phrases in the patient's medical record, such as a diagnosis of Diabetes.
In addition, patients can communicate with the physician's office to request an appointment, request a prescription renewal, update demographic information, update immunisation status, or update a health maintenance procedure. The patient can also request advice from an advisory nurse or from his or her own physicians. The most popular features of the integrated PHR are access to lab test results and communication with physicians. As of September 2007, 26,000 patients login to PAMF's MyChart each month, sending 20,000 secure messages.
