Key Points
Question
What factors are associated with gaps in the HIV preexposure prophylaxis (PrEP) continuum of care and where in the continuum do HIV infections occur?
Findings
In this cohort of 13 906 insured adults linked to PrEP care, individuals aged 18 to 25, African American individuals, Latinx individuals, women, individuals with lower socioeconomic status, and individuals with a substance use disorder were more likely to experience gaps in the PrEP continuum of care. Attrition along the continuum was associated with incident HIV infection.
Meaning
These findings suggest that comprehensive strategies are warranted to improve PrEP continuum of care outcomes in high-priority populations.
