Summary
Emergency department patients’ engagement with HIV testing educational videos predicted acceptance. Those who spent more time responding and had knowledge gaps were more likely to accept HIV tests.
Area of Science:
- Public Health
- Behavioral Science
- Clinical Medicine
Background:
- Emergency departments (EDs) are crucial settings for public health interventions.
- HIV testing acceptance can be improved through targeted educational strategies.
- Understanding patient factors influencing HIV test uptake is essential for effective interventions.
Purpose of the Study:
- To identify predictors of Human Immunodeficiency Virus (HIV) test acceptance among ED patients after an educational video intervention.
- To explore the relationship between patient demographics, pre-intervention knowledge, and HIV testing behavior.
Main Methods:
- A study involving 202 ED patients who viewed an educational video on netbook computers.
- Data collected pre- and post-intervention, including HIV test offer and acceptance.
- Analysis of response times, pretest knowledge accuracy, and demographic factors.
Main Results:
- 43% of patients accepted an HIV test after the video intervention.
- Longer response times to post-intervention questions correlated with test acceptance.
- Incorrect answers on pretest HIV symptom questions predicted higher test acceptance.
- White patients were less likely to accept testing compared to Black, Latino, or 'Other' ethnic groups.
Conclusions:
- Patient engagement, knowledge deficits, and demographic factors are significant predictors of HIV test acceptance in the ED.
- Time spent considering the HIV test offer is a strong indicator of acceptance.
- Findings can inform the development of targeted behavioral health interventions for underserved populations in clinical settings.
