The North American AIDS Cohort Collaboration on Research and Design (NA-ACCORD) was established in 2006 as the North American regional representative of the International epidemiology Databases to Evaluate AIDS (IeDEA). Comprised of more than 20 classical and clinical collaborating cohorts, NA-ACCORD is designed to be widely representative of adults in HIV care in the United States and Canada. Over 200 sites contribute data on over 190,000 adults with HIV.

NA-ACCORD has a multi-disciplinary group of collaborators that span disciplines such as basic science, clinical research, epidemiology, data informatics and biostatistics. Collectively, our group is poised to frame, design, and successfully answer key questions about the HIV epidemic treatment and clinical care. The NA-ACCORD has established a unique scientific platform to address clinical issues that are now of paramount importance in the modern treatment era.

The goals of NA-ACCORD are:

1. Unleash insights into the evolution of HIV in North America: Describe the dynamic landscape of HIV care, treatment, progression and health outcomes in the modern treatment era.
2. Generate new knowledge regarding the impact of a chronic viral infection on aging: Investigate the influential and causal factors driving the increased burden of comorbidities and multimorbidity, and points of intervention to increasing health span.
3. Push the boundaries of longitudinal collaborative study design: Leverage data science principles and tools to expand our novel methods that utilize high-quality longitudinal data from numerous sources for research inference.
4. Be an essential regional and methodological partner: The  IeDEA global collaboration is uniquely positioned to address research questions of inter-regional and global importance.
