Regional Informatics

On May 3, 2008, our Memphis-based health information exchange has been in clinical operation for two years.

Clinical Data

From our February estimates, the system has over 300,000 procedures codes, 2.6 million diagnostic codes. On a daily basis, the system adds approximately 33,000 encounters, 850 microbiology tests, 1,200 chest x-ray reports and some 80,000 laboratory test results.

The Exchange grants secure access to almost 3 million patient encounters.

• Total number of unique individuals - 1,050,000
• Total number of unique individuals with clinical data (not just claims) - 809,000

We are still working on the latest inventory of specific data elements.

System Users

The Exchange currently has 356 people using the system for clinical care.

• Physician / Provider roles - 199
• Nurse roles - 109
• Registrars and unit clerk functions - 48

These numbers will change as the last major system goes "near real time" in the next few weeks and as more ambulatory care providers are introduced to the program. The number of clinicians will increase and the number of registrars and unit clerks will decrease dramatically.
