  • Biomedical Prevention
  • Continuum of Care
  • Implementation Science


Upon successful completion of this activity, learners will be able to:

  • Employ interventions to enhance linkage to and engagement and retention in HIV care
  • Apply strategies to optimize antiretroviral therapy and pre-exposure prophylaxis adherence

The target audience for Adherence 2021 conference includes physicians, nurses and nurse-practitioners, pharmacists, psychologists, behavioral scientists, social scientists, public health specialists, epidemiologists, social workers, case managers, peer educators and navigators, and community health workers working in the field of HIV medicine. The conference may also be of interest to individuals who wish to implement and advocate for effective, evidence informed HIV policies and interventions in their respective communities and countries.

Adherence 2021
is currently pending application of accreditation for physicians, nurses/nurse practitioners, pharmacists, psychologists, and other credentials.

Adherence 2021 is made possible through an educational grant from Gilead Sciences. Other educational grants and corporate sponsorships will be announced as they are received.


Adherence 2021 will consist of 2 and 1/2 days of plenary sessions, panels, oral abstract presentations, and e-poster abstracts. This will be preceded by 1/2 day of pre-conference sessions.

The conference will focus on state-of-the-science evidence, best practices, and the practical, real-world implementation of behavioral, clinical, structural, and other interventions to maximize the therapeutic and preventative effects of antiretroviral agents. The conference will also provide a forum for discussion and presentation of implementation science focused on closing evidence-to-practice gaps across the HIV prevention and care continua, as well as community engagement in planning, implementing, and monitoring HIV responses in their communities.


The Adherence 2021 theme is New Targets, New Opportunities. The conference will feature a keynote address, memorial lecture, and memorial colloquium, as well as plenary addresses, panel discussions, oral abstract sessions, and an e-poster session.


At the conclusion of this educational activity, learners should be able to:

    • Employ interventions to enhance linkage to and engagement and retention in HIV care
    • Apply interventions to enhance and support optimal patient adherence to ART and PrEP
    • Integrate into clinical practice strategies to manage syndemic conditions associated with HIV
    • Describe the framework for designing implementation strategies for successful HIV responses
    • Promote engagement by communities in planning, implementing, and monitoring HIV responses

The Adherence 2021 conference program may be viewed here. Faculty will be added to the program as they are confirmed.
