Study summary

People who inject drugs are at risk of injection-related infections, like abscesses or infective endocarditis. The Injection-Related InfectionS (IRIS) program hopes to improve treatment for participants by providing a low-barrier, one-stop shop model for people who inject drugs who experience injection-related infections to access more holistic and compassionate care. IRIS is a non-randomized clinical trial, meaning that it offers a specific program to eligible patients. This program offers care for substance use and infectious disease with additional peer support and systems navigation, if interested. The investigators anticipate enrolling 80 participants in the intervention and will follow participants throughout the infection treatment period (estimated 6-12 weeks). The investigators will collect information at the time of enrolment, at the 6-month mark, and monthly via electronic medical chart review. The investigators will use an interrupted time series analysis to evaluate the impact of the intervention on rates of treatment completion, emergency department visits, hospitalizations, and death, before versus after the intervention.

Study arms

  • Experimental
    Intervention group

    Participants in the IRIS program will be offered a one-stop, low-barrier combined care model to address their injection-related infections. Specific program components include: (1) Diagnosis and treatment of injection-related infections; (2) Substance use treatment (3) Peer support; and (4) Care coordination/systems navigation.

    Other: Holistic injection-related injection treatment

Interventions

  • OtherHolistic injection-related injection treatment

    Participants in the intervention group will be provided additional supports to address their social and medical needs, including infectious disease management, addictions medicine, peer support, and systems navigation. Each participant will receive individualized care depending on their unique needs.

What researchers measure

Primary outcomes

  1. Number of emergency department visits and hospital readmission

    Time frame: Within 30 days of initial hospital admission or program enrolment

Secondary outcomes

  1. Completion of intended course of treatment for the injection-related infection

    Investigators will record whether or not participants have completed the intended course of treatment for their injection-related infection (e.g. completed course of antibiotics - YES or NO).

    Time frame: Within 6 months of initial hospital admission or program enrolment

  2. Number of hospital readmissions specifically for the infection that was the primary reason for program enrolment

    Time frame: Within 90-days of hospital discharge or program enrolment

  3. Number of emergency department visits

    Time frame: Within 90-days of hospital discharge or program enrolment

  4. Number of new initiations or record of continuation of substance use treatment

    Time frame: Within 90-days of hospital discharge or program enrolment

  5. Mortality rates

    Time frame: Within 6-months of hospital discharge or program enrolment

  6. Rates of program drop-out and reasons for discontinuation

    Time frame: Within 6-months of hospital discharge or program enrolment
