Brief Summary

Vending machines are an innovative strategy shown to increase access to naloxone, a medication used to reverse opioid overdose. The aim of this proposal is to study the reach of a community-initiated, stakeholder engaged adaptation of naloxone distribution, VEnding machine Naloxone Distribution for Your community (VENDY) program.

Outcome Measures

Primary Outcomes (1)

  • Reach

    Reach will be assessed using monthly counts of naloxone distribution in the 6 months before and after VENDY implementation. Naloxone counts will include distribution from all sources within the organization and captured through pharmacy fills from the electronic health record and distribution tracking logs. Naloxone machine distribution will be added to the total monthly count in the post implementation phase and obtained using the vending machine electronic software (reporting date and time of distribution) or (for kiosks) the staff monthly refill tracking log capturing quantity of naloxone kits required to fill the machine (captured at least monthly).

    the 6 months pre VENDY implementation and the 6 months post VENDY implementation

Secondary Outcomes (4)

  • Adoption

    At the end of program development (program development is the first phase in which each site is developing VENDY over a 6-18 month period of time)

  • Fatal Opioid Overdose Events-Effectiveness

    pre-implementation in the year prior to a live VENDY program and post implementation in the year following live VENDY program

  • Fidelity-Implementation

    the 6 months following VENDY implementation

  • Maintenance

    the 6 months following the initial implementation phase (6 months)

Study Arms (1)

VENDY

EXPERIMENTAL

Each participating site will install at least 1 machine (vending or kiosks) in the respective community for naloxone distribution.

Behavioral: VENDY

Interventions

VENDYBEHAVIORAL

At least 1 machine (vending machine like a snack machine or a machine like a newspaper kiosk) will be placed in the respective community served by the participating organizations. Any person in the community can get naloxone from the machine. The vending machine will require a code that will be placed on the machine for anyone to use. The kiosks are a box that you simply pull open and naloxone can be obtained. Naloxone kits will be provided for free as part of the current naloxone distribution program within each respective organization.

VENDY

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Any person in the community who desires to obtain naloxone will be able to use the machines

You may not qualify if:

  • Inability to enter a code on a vending machine or open a kiosk.
