As  health care delivery within the global community moves towards a  greater degree of digitization, there will likely be more technical  challenges health care delivery organizations must face as they move  from their existing legacy systems to those that are digital.

In  this Discussion, you will compare and contrast an electronic medical  record (EMR), electronic health record (EHR) and a personal health  record (PHR).

The Institute of Medicine has recommended that electronic health records (EHR) should possess eight core functions including:

• Health information and data
• Result management
• Order management
• Decision support
• Electronic communication and connectivity
• Patient support
• Administrative processes and reporting
• Reporting and population health

To  prepare for this Discussion, research the Internet for information on  EHR, EMR, and PHR, such as can be found at the Web site, http://www.healthit.gov/providers-professionals/benefits-electronic-health-records-ehrs.

In this Discussion, address the following:

•  Identify the primary differences between an electronic medical record  (EMR), electronic health record (EHR), and a personal health record  (PHR).
•  What are the primary technical and design complexity issues with  delivering these eight core functions? Choose one issue and identify how  you would address it.
• How does the integration that is required  between the EHR and other middleware products vary depending on whether  one is running locally, on an office-based LAN, or online within an ASP  model?

Illustrate your points in the context of a patient’s visit to a health care provider.
