To evaluate the impact of an pre‐exposure prophylaxis (Pr) education intervention on Pr awareness and use among men who have sex with men () attending a sexually transmitted diseases () clinic.

Data Sources/Study Setting

Men who have sex with men STD clinic patients.

Study Design

We estimated a difference‐in‐differences linear regression model, comparing whose first visit to the clinic was before (“control”) or after (“treatment”) intervention implementation and controlling for patient.

Data Collection/Extraction

We used self‐reported data on PrEP awareness and use from STD clinic intake forms.

Principal Findings

Pre‐exposure prophylaxis awareness between first and second clinic visits increased 27.2 percentage points (pp) in the treatment group, relative to 13.7 pp in the control group. Similarly, Pr use increased 7.1 pp in the treatment group versus 2.4 pp in the control group. Based on adjusted estimates, the Pr intervention increased Pr awareness by 24 pp ( < .01) and Pr use by 5 pp ( = .01), increases of 63 percent and 159 percent relative to the 6 months prior to the intervention.


A brief, scalable clinic Pr education intervention led to significantly increased Pr awareness and use among . Health care providers should consider implementing brief Pr education interventions in sexual health care settings.
