Is this trial a fit for you?

Likely a good fit

People aged 15 or older experiencing a suspected opioid overdose within the dispatch area who can be reached by volunteer responders are the intended beneficiaries.

Probably not a fit

People outside the dispatch coverage area, those with non-opioid emergencies or unwitnessed events where no responder can be alerted, and cases needing immediate advanced medical care may not receive benefit from this intervention.

What this trial studies

This two-year pilot integrates a smartphone app with national emergency dispatch to alert trained volunteer responders who carry naloxone to suspected opioid overdoses. Volunteers complete an opioid overdose and naloxone course plus a first aid course, register in the app, and are reimbursed for purchasing naloxone kits. The trial will collect quantitative data on feasibility, acceptability, safety and mortality outcomes, and will follow each registered volunteer for one year. Several sub-studies, including qualitative interviews with recipients and responders, will explore experiences and implementation barriers.

Why it matters

Potential benefit: If successful, the program could shorten time to naloxone administration, reduce overdose deaths and complications, and provide lifesaving care before ambulance arrival.

How similar studies have gone: Volunteer responder systems have improved survival in out-of-hospital cardiac arrest and community naloxone distribution has reduced opioid deaths, but combining dispatcher-linked smartphone responders with naloxone delivery for overdoses is relatively novel and underexplored.

3. Download and register oneself as a user on the project-specific volunteer first responder app on a smartphone
4. Purchase naloxone from a pharmacy and receive reimbursement for the full cost of the purchase upon submission of the pharmacy receipt

Exclusion Criteria for volunteer first responder:

1\. Displaying inappropriate behavior during the education day (or otherwise in time, as witnessed or experienced by course instructors or the project team). Such conduct could for example be to not follow the guidelines of low-arousal (non-confrontational) approach in emergencies.

Inclusion Criteria for overdose alerts:
