Allscripts is the health record system for UT Physicians. Allscripts contains data on patients seen in outpatient UT clinics, including laboratory data.

Allscripts does not contain information on patients seen in an inpatient setting. Tables of commonly requested information are presented. Data are loaded into the CDW nightly.

The EHR contains demographic information on several million patients. However, the Clinical Data Warehouse has measures which reduce the total counts:

• Exclusion of records without a complete encounter at a UT Physicians clinic
• Exclusion of records missing all of the clinical data elements shown here
• De-duplication algorithms to account for duplicate records

Thus, the final counts loaded into our i2b2 instance will be lower than the total records in Centricity.
