Implementation Science for HIV Prevention and Treatment in Indigenous Communities: a Systematic Review and Commentary

Area of Science:

• Implementation science
• Indigenous health
• HIV/AIDS research

Background:

• HIV prevention and treatment services require effective implementation strategies within Indigenous communities.
• Existing research often lacks community-led approaches and focuses primarily on behavioral interventions.

Purpose of the Study:

• To systematically review implementation research for HIV services in Indigenous communities in the Americas and Pacific.
• To identify strengths, opportunities, and principles for Indigenous-led HIV implementation science.

Main Methods:

• Systematic literature review of implementation research.
• Analysis of studies focusing on HIV preventive or treatment services in Indigenous communities.
• Identification of common barriers, facilitators, and research methodologies.

Main Results:

• 31 studies reviewed, emphasizing cultural tailoring and community involvement (nearly half used CBPR).
• Key barriers included stigma, geography, confidentiality, language, and mistrust.
• Limited research on biomedical HIV prevention and treatment; no randomized implementation trials found.

Conclusions:

• Community engagement and Indigenous-led intervention development are vital for HIV services.
• Addressing social determinants of implementation is essential for success.
• An indigenized implementation science can improve HIV service acceptability and reach while honoring Indigenous knowledge.
