The Veterans Health Administration (VHA) is increasingly dependent upon data. Most of its employees generate and use vast amounts of data on a daily basis. To improve our capacity for data analysis while providing the most efficient and the highest quality health care to our Veteran patients, VHA, working with the VA Office of Information and Technology, implemented a health data warehouse. Central to this plan is consolidating data from disparate sources into a coherent single logical data model. The Corporate Data Warehouse (CDW) is the physical implementation of this logical data model at the enterprise level for VHA. Although the CDW initially began to store data as early as 2006, a renewed effort began in 2010 to accelerate CDW's content by including more subject areas from Veterans Health Information Systems and Technology Architecture (VistA) and content from other existing national data systems. CDW supports fully developed subject areas in its production environment as well as supporting rapid prototyping by extracting data directly from source systems with very minor data transformations. The Regional Data Warehouses and the Veterans Integrated Service Network (VISN) Data Warehouses share content from CDW and allow for greater reporting flexibility at the local level throughout the VHA organization.

The Converged Registries Solution (CRS) has been replaced by the Veterans Integrated Registries Platform (VIRP). The information contained in this entry discusses the CRS prior to its replacement. The Converged Registries platform was a hardware and software architecture designed to host individual patient registries and eliminate duplicative development effort while maximizing VAs ability to create new patient registries. The common platform included a relational database, software classes, security modules, extraction services and other components. The Converged Registries obtained data from the Corporate Data Warehouse (CDW), directly from the Veterans Health Information Systems and Technology Architecture (VistA) as well as by direct user input. Registries Projects - Embedded Fragment Registry (EFR), Eye Injury Data Store, Traumatic Brain Injury (TBI) Registry and Veterans Implant Tracking and Alert System (VITAS).

The VA's Veteran Health Administration, in support of PL 112 260 established an Airborne Hazards and Open Burn Pit Registry to study the potential exposure of concern that may result in long-term health impacts to Veterans.

The Contract Administration and Management System (CAMS) is a data management system designed specifically for the Veterans Health Administration Office of Facilities Management (FM) for the management of contract and funding data. It provides a means of sorting and tracking data related to major Architect-Engineer and construction contracts such as contract type, project locations, project status, and contract funding.

The Breast Care Registry is an Office of Women's Health sponsored intranet based registry providing data for the longitudinal tracking of breast care.

The Consolidated Copayment Processing Center (CCPC) database contains Veteran patient contact and billing information in order to support the printing and mailing of patient billing statements. The CCPC system is designed to handle first-party medical debt billing information. First-party billing is defined as a patient debt for which the patient is responsible for payment (normally co-payment) for health care treatment. This differs from third-party billing where a third party (e.g., insurance company, Health Maintenance Organization (HMO)) is primarily responsible for repaying the VA. CCPC does not handle third-party billing information. The Veterans Health Information Systems and Technology Architecture Accounts Receivable (AR) module collects information for CCPC at every Veterans Affairs Medical Center (VAMC). A daily batch process is used to collect and transmit the information to the VA Austin Information Technology Center. All collected patient and billing information is kept active on CCPC for a period of one month. A master list containing six months activity is archived for reference should historical information be needed. The users of this database include the VAMCs, Veterans Health Administration Chief Business Office, and the patients who receive billing statements.

The Community Nursing Home (CNH) database contains a list of all Community Nursing Home facilities under local contract to Veterans Health Administration (VHA). CNH facilities are not managed by VA. Instead, CNH facilities are private or public facilities licensed by the state where they provide the patient services. Each day all Veterans Affairs Medical Center (VAMC) that have a contract with a CNH enter information about the CNH into the Fee Basis module of Veterans Health Information Systems and Technology Architecture. This information is sent via MailMan to the VA Austin Information Technology Center where it is collected in a queue. A quarterly batch process is run on the queue. VAMCs that have sent invalid data or VAMCs that have contracts and did not send data are notified. Valid data is processed and used to update the database. Quarterly reports are sent to the CNHs, VAMCs, Veterans Integrated Service Networks (VISNs), Geriatrics & Extended Care Strategic Health Care Group, and VA Central Office (VACO).

The Community Residential Care Report is a listing of all facilities approved for residential care by the VA. These facilities are privately run operations not affiliated with the VA. They provide room, board, supervision, and other non-medical care to Veteran patients who cannot care for themselves but do not require the services of a Veterans Affairs Medical Center (VAMC). Information about these facilities is entered into the Fee Basis module of the Veterans Health Information Systems and Technology Architecture (VistA) by every VAMC that has an agreement with a facility. This information is sent via MailMan to the VA Austin Information Technology Center where it is collected in a queue and processed quarterly. VAMCs that have sent invalid data or VAMCs that are aligned with residential care facilities and did not send data are notified. Valid data is processed and used to update the database. Quarterly reports are sent to VAMCs, Veterans Integrated Service Networks (VISNs), Geriatrics & Extended Care Strategic Health Care Group, VA Central Office (VACO), and researchers interested in residential care information.

Civilian Health and Medical Program of the Department of Veterans Affairs (CHAMPVA) is a health care benefit program designed for the dependents of certain Veterans. Administered by the Health Administration Center (HAC), Denver, Colorado, CHAMPVA shares the cost of necessary health care services and supplies with eligible beneficiaries. The CHAMPVA Eligibility & Payment Functions (CVA) database is used by HAC for the administration of the CHAMPVA program.

The Clinical Case Registries (CCR) replaced the former Immunology Case Registry and the Hepatitis C Case Registry with local and national databases. The CCR:HIV and CCR:HCV are administrative and clinical databases designed to provide population-based data on VA patients infected with Human Immunodeficiency Virus (HIV) and/or Hepatitis C virus (HCV). Each Veterans Health Information Systems and Technology Architecture (VistA) system contains a local CCR where patients who are potentially HIV or HCV infected are identified based on International Classification of Diseases (ICD-9) codes and/or positive antibody test results. The local HIV or HCV coordinator must review these cases to determine which patients are truly infected and should be added to the local registry. The local CCR provides extensive reporting capabilities to the local HIV and HCV clinicians to monitor their patient population. The local CCR software also extracts data elements from multiple VistA packages and transmits Health Level Seven (HL7) messages to the national database at VA Austin Information Technology Center. The national database is used for monitoring clinical outcomes, assessing resource utilization and quality assurance.
