Development of a Multilevel HIV Prevention Intervention for the Emergency Department

Official title

mSYNC: an mHealth SYNdemic-based Consultation-liaison HIV Prevention Intervention for the Emergency Department

Overview

The goal of this clinical trial is to pilot test a psychosocial-behavioral mobile health (mHealth) human immunodeficiency virus (HIV) prevention intervention in people who use drugs presenting to the emergency department (ED). The main question the study aims to answer is: is the intervention acceptable and appropriate? Participants will use the mHealth app while waiting in the ED and also at home for 90 days. Participants will be asked to complete surveys at baseline, before leaving the ED, and at 30-, 60-, and 90-day follow up visits.

Detailed description

"mSYNC" (mHealth SYNdemic-based Consultation \& liaison) is an mHealth HIV prevention intervention to be initially delivered at point-of-care during a visit to the emergency department with continued on demand access to intervention app at home. mSYNC simulates hospital-based consultation and liaison psychology service by intervening on the interrelated health risk behaviors, mental health issues, and structural/treatment needs (e.g., housing, drug use treatment). Capitalizing on the syndemic domino effect, mSYNC aims to promote prevention via entry into at least one of three interacting pathways: decreased HIV/drug use risk behaviors, decreased severity of mental health symptoms, and increased linkage to services. A pilot single-arm feasibility test will be conducted to assess patient-level implementation outcomes of acceptability and appropriateness of the mHealth intervention. Secondarily, change over time will be explored for HIV risk, drug use, mental health symptoms, and linkage to care. The study will take place in two urban emergency departments in Boston, Massachusetts. A sample of N=100 people who use drugs (PWUD) who also belong to other key HIV risk groups (transgender women, men who have sex with men \[MSM\], Black/Latinx/Indigenous people) will be enrolled during a visit to the emergency department. Research staff will pre-screen individuals checked-in and waiting in the emergency department for potential eligibility via information from electronic medical chart (HIV risk or drug use indicator). Staff will then approach potentially eligible patients identified from this pre-screen to describe the study and invite them to be screened for eligibility. Once screened eligible, participants will complete a baseline survey and asked to engage with the mHealth intervention app during their time in the ED (environment- and person-driven intervention dosage). Before discharge, participants will complete a brief feedback survey and asked to use to mHealth at home for at least one time a week for the next 90 days (environment- and person-driven intervention dosage) with the help of automatic notifications personalized to the person. Participants will complete a remote follow-up at 30, 60, and 90 days consisting of a quantitative survey and exit interview (90-day follow-up only).

Interventions

• Behavioral mSYNC
  mSYNC in an mHealth HIV prevention intervention to be initially delivered at point-of-care during a visit to the emergency department with continued on demand access to intervention app at home. Taking a behavioral medicine approach, mSYNC simulates hospital-based consultation \& liaison psychology service by intervening on interrelated health risk behaviors, mental health issues, and structural/treatment needs. The mHealth app includes modules with motivational interviewing for HIV/drug use ris

Primary outcome measures

• Acceptability of intervention assessed via AIM [Time frame: immediate post intervention exposure, 90-day follow-up]
• Acceptability: Usability of mHealth intervention assessed via SUS [Time frame: immediate post intervention exposure, 90-day follow-up]
• Acceptability of intervention assessed qualitatively [Time frame: 90-day follow-up]
• Appropriateness of intervention assessed via IAM [Time frame: immediate post intervention exposure, 90-day follow-up]
• Appropriateness: Intervention engagement assessed via UES [Time frame: immediate post intervention exposure, 90-day follow-up]
• Appropriateness of intervention assessed qualitatively [Time frame: immediate post intervention exposure, 90-day follow-up]
