CHIME VA Data Core Consultation

The Veterans Health Administration (VA) maintains a central data repository with health information from the electronic medical records of over 21 million Veterans in the United States. Data fields include (but are not limited to) age, gender, race, ethnicity, zip code, dates of outpatient and inpatient encounters, conditions, procedures, lab results, vital signs, medications, prescription refills, clinical notes, radiology reports, costs, vital status, location of care, and national provider identification number. Data files from the Center for Medicare and Medicaid Services (CMS), including Medicare, Medicaid, and the US Renal Data System, are also available.

The Center for Healthcare Improvement and Medical Effectiveness (CHIME) VA data core, located at the San Francisco VA, facilitates access to VA data for clinical research and quality improvement projects conducted by UCSF's VA-affiliated investigators. The CHIME VA Data Core:

  1. Provides consultation regarding available data.
  2. Facilitates necessary paperwork and approvals.
  3. Ensures that use of VA data meets all regulatory requirements.
  4. Assists with identifying, extracting, and merging variables of interest.

Please note that obtaining a VA appointment and access to VA data may require up to 40 hours of time over a period of 3 to 6 months prior to starting any data analysis. Although the VA data core can help investigators identify and extract data fields of interest (e.g., age, ICD-10 codes, CPT codes, lab results, vital status), it does not provide data cleaning (e.g., eliminate illogical data), perform analyses (e.g., calculate average age of patients with diagnosis of interest) or run statistical models (e.g., evaluate association between lab value and mortality). Please feel free to contact Katy Williams with any questions.
