This database is part of the National Medical Information System (NMIS). The National Health Care Practitioner Database (NHCPD) supports Veterans Health Administration Privacy Act requirements by segregating personal information about health care practitioners such as name and social security number from patient information recorded in the National Patient Care Database for Ambulatory Care Reporting and Primary Care Management Module.

The Home Based Primary Care (HBPC) database receives and compiles data from local Hospital Based Home Care (HBHC) sanctioned programs at Veterans Affairs Medical Centers (VAMCs) that run home care programs under the Home Based Primary Care program. The primary purpose is to provide HBPC management with case mix, case load, and other performance information. The HBPC information system is referred to as HBC at the VA Austin Information Technology Center and as HBHC at the local level. The HBHC automated a paper-based system of reporting home care episodes. When an admission form is completed, an episode is opened and input into HBHC for a potential home care patient. The patient is evaluated and accepted to or rejected from the program. When a patient leaves the program for any reason an episode is closed and a discharge form completed and input into HBHC. HBHC runs a nightly extract of information within the Veterans Health Information Systems and Technology Architecture. Extractions include information on all Patient Care Encounters (PCEs) with the patient and home visits made by home care providers. Details of which provider(s) made the visit, the date, any diagnosis and any procedures performed are included. Each local application sends its data to the Austin HBC database on a monthly basis. A monthly report is prepared based on this information identifying the active cases at each VAMC. A more detailed quarterly report is produced that includes national comparisons among sites.

Dental Encounter System (DES) is an automated health care application designed to capture critical data about the operations of VA Dental Services. Information on completed procedures is gathered for each patient encounter through the Dental Record Manager software, which is a VA Computerized Patient Record System Class I adjunct application. This DES information is linked and includes encounter date, patient, provider, procedures, diagnosis codes, and additional associated qualifiers. DES productivity is measured using weighted work units known as relative value units (RVUs). RVU values are determined cooperatively by the Dental Coding Committee and Decision Support System (DSS) staff. One RVU is a measure of work effort and represents one minute of the average provider's time (presuming the provider is supported with one dental assistant and one treatment room) and is reported as a value with each procedure reported to DES. DES transactions are sent to the Austin Information Technology Center (AITC) database using standard Health Level Seven (HL7) messaging and the VA Vitria Interface Engine. These batched HL7 messages are parsed at the AITC and placed in a flat database file.
