Enhancing HIV Pre-exposure Prophylaxis Practices via an Educational Intervention

Pre-exposure prophylaxis (PrEP) for HIV involves using antiretroviral drugs to prevent individuals at high risk from acquiring HIV infection. Most practicing primary care providers believe PrEP to be safe and effective, but less than half have prescribed or referred for PrEP. Attitudes and prescribing patterns among house officers have not been well described previously.

Can an educational intervention enhance HIV PrEP practices among internal medicine house officers?

This study relied on a pretest/posttest design. All categorical trainees at a medium-sized internal medicine program were offered a baseline survey to assess their knowledge on PrEP. This was followed by a PrEP-focused educational intervention and a postintervention survey.

Likert scales captured perceptions regarding safety, effectiveness, barriers, factors that would promote PrEP use, potential side effects, impact on risk-taking behavior, and provider comfort level in assessing behavioral risks and in PrEP prescribing. Data were analyzed using descriptive statistics, Wilcoxon signed rank test, and the Kruskal-Wallis test. Significance was accepted for P < 0.05.

Forty-eight (100%) trainees participated in the educational session, 45 (94%) in a preintervention survey, and 36 (75%) in a postintervention survey. Before PrEP training, 22% of respondents were unaware of PrEP, 78% believed PrEP was effective, 66% believed PrEP was safe, 62% had fair or poor awareness of side effects; 18% of residents had referred for or prescribed PrEP, and 31% believed they were likely to prescribe PrEP in the next 6 months. After the intervention, 94% of trainees believed PrEP was effective (P < 0.001), 92% believed PrEP was safe (P < 0.001), and two-thirds believed they were likely to prescribe PrEP in the next 6 months.

Brief, focused training on HIV prevention promotes awareness, acceptance, and likelihood of prescribing PrEP by internal medicine trainees.
