At each SC, each of the three screening strategies (targeted, universally offered opt-in, and universally offered opt-out) will be employed, one at a time, for a period of 8 months and a total study period of 24 months.
All patients 14-24 years of age that are seeking care in participating EDs during the study period will be given the opportunity to complete the computerized sexual health survey (cSHS) on a tablet. The cSHS asks patients to decide whether they want to be tested for HIV and contains questions based on the 2021 update to the CDC PrEP eligibility guidelines that stratify risk for HIV exposure and acquisition. The patient will agree (or not) to completing the cSHS on the tablet. The cSHS is not mandatory, so a patient may decline to use the tablet, and their parent or guardian may decline as well.
Throughout study activities (for all screening strategy phases), certain cSHS results will trigger real-time EHR-integrated decision support for clinicians on whether HIV testing should be ordered and whether counseling/prescription for PrEP should be provided. It also implements a text messaging platform with the patient for basic PrEP information and enrollment into a digital health PrEP linkage platform.
Additionally, all SCs will abstract baseline (plus 3 months) EHR data for all eligible patients to be used as a comparator in the analysis.
