The North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) began in 2006 as the North American regional representative of the International epidemiologic Databases to Evaluate AIDS (IeDEA). Comprised of over 20 collaborating cohorts, NA-ACCORD is widely representative of people who linked into HIV care in the United States and Canada. Sites contribute data on over 190,000 people with HIV.

NAACCORD Sites

NA-ACCORD has established a multi-disciplinary group of collaborators that span disciplines such as basic science, clinical research, epidemiology, data science, machine learning, and intificial intelligence. Collectively, our group is poised to harness >20 years of longitudinal data to answer key questions in research and clinical practice today and continue to develop methodology for longitudinal collaborative study designs for accurate research inference. The NA-ACCORD has established a unique scientific platform to improve health and advance longitudinal research technology.

Linked to Care

  • CD4 at entry to care

  • CD4 at ART

Retention: >=2 HIV primary care visits, >90 days apart, in the year

See full definition
>=2 HIV primary care visits per calendar year, >90 days apart, among those with >=1 visit after cohort enrollment and before the end of the study period (observations in the year of cohort initiation or year of patient death are excluded); CD4 and HIV-1 RNA measurement dates were used as visit proxies in British Columbia, Argentina, and Peru.

ART use: On ART >=1 month in the year

See full definition
>1 month on a regimen consisting of 3 or more active antiretroviral agents per calendar year, among those with >=1 HIV primary care visit in the calendar year.

CD4 at entry: Earliest CD4 count within 6 months of entry to cohort

See full definition
Earliest CD4+ count within 6 months of (before or after) enrollment in the cohort, excluding those with any recorded ART use or HIV-1 RNA viral load < 200 copies/mL prior to the eligible CD4+ counts.
