Male individuals and those with occupational or community injuries were more likely to receive triple therapy postexposure prophylaxis (PEP) for HIV. Completing the full 23-day PEP course was also associated with male sex and injury type, particularly with initial triple therapy.

Area of Science:

  • Public Health
  • Infectious Disease Epidemiology
  • Antiretroviral Therapy

Background:

  • Postexposure prophylaxis (PEP) is crucial for preventing HIV transmission after potential exposure.
  • Understanding factors influencing PEP prescription and adherence is vital for public health programs.
  • Antiretroviral PEP regimens vary in complexity and duration, impacting patient management.

Purpose of the Study:

  • To identify characteristics associated with the initial prescription of double versus triple antiretroviral PEP.
  • To determine factors linked to completing the full 23-day course of PEP after a 5-day starter kit.
  • To inform optimization of HIV prevention strategies within population-based programs.

Main Methods:

  • A retrospective analysis of individuals receiving a 5-day starter kit of double or triple antiretroviral PEP.

  • Data collected on kit dispensation and follow-up for the remaining 23 days of PEP.
  • Logistic regression models used to identify independent predictors of triple therapy initiation and 23-day follow-up.

    • Main Results:

    • Male sex, occupational mucocutaneous injuries, and community needlestick injuries were associated with receiving triple therapy starter kits.
    • Being male, experiencing community mucocutaneous incidents or needlestick injuries, and receiving triple therapy starter kits predicted 23-day PEP follow-up.
    • 20% of individuals received triple therapy starter kits, and 29% completed the full 23-day PEP course.

    Conclusions:

    • Prescription of triple therapy starter PEP is influenced by patient demographics and injury type.
    • Completion of the full PEP regimen is associated with male sex, specific injury types, and initial triple therapy prescription.
    • These findings highlight key factors for targeted interventions to improve PEP adherence and effectiveness.
