Impact of a kiosk educational module on HIV screening rates and patient knowledge

We assessed the effect of a kiosk educational module on HIV screening rates and patient knowledge about HIV testing. The evaluation was performed in a walk-in clinic offering routine HIV screening. During alternating two-week periods, patients were referred either to view a kiosk-based, educational module prior to receiving usual care, or the kiosk module was turned off and no alterations to care processes were made. The primary outcome was HIV testing rate. The secondary outcome was knowledge about HIV rapid screening, as measured with a questionnaire. There were 71 patients in the kiosk periods and 79 patients in the usual-care periods. The overall HIV testing rate was 41%. The kiosk period was not associated with greater odds of HIV testing (OR 0.7; 95% CI: 0.4-1.4). In 44 patients who completed the knowledge survey, the kiosk group was strongly associated with increased knowledge (predicted increase in knowledge score: 1.3; 95% CI: 036-2.1). The brief kiosk educational module did not improve HIV screening rates, but it increased overall patient knowledge about HIV testing.
