Study summary

This pilot study evaluates the needs of opioid users for a device-based intervention for opioid overdoses. The results of this one-time short questionnaire will inform development of a novel naloxone delivery device.

Read the detailed description

All opioid overdose related deaths can be prevented with the timely delivery of Naloxone. This study is a one-time, preliminary survey of participants with opioid use disorder to assess the need for, and community attitudes towards, a wearable device capable of autonomously detecting and responding to an opioid overdose. The results of this survey will be used to guide ongoing development of a de novo device. This study will be conducted over a 3 month period and survey participants from the Kensington Neighborhood in North Philadelphia.

Groups and cohorts

  • Patient Participants

    This group of participants will complete a survey about their opioid use history and their preferences for a device-based intervention. They will then participate in a semi-structured interview to provide feedback on non-functional, "looks-like" prototypes of such a device.

    Other: Survey · Other: Interview

Interventions

  • OtherSurvey

    Participants will complete a survey about their opioid use history, its impact on their lives, their current strategies for preventing or reversing opioid overdoses, and their preferences for a device-based intervention.

  • OtherInterview

    Participants will participate in a semi-structured interview, during which they will provide feedback on non-functional, "looks-like" prototypes of a naloxone delivery device.

What researchers measure

Primary outcomes

  1. Community Need for a Device-based Opioid Overdose Intervention

    We aim to characterize the degree of need for a device-based opioid overdose intervention. These were extracted from the participant survey questions as well as from the words, phrases, and sentences used by participants during the interview.

    Time frame: Day 1

Secondary outcomes

  1. Functional and Aesthetic Preferences for Device-based Opioid Overdose Intervention

    We aim to characterize the functional and aesthetic preferences of the participant population for a device-based opioid overdose intervention. These were extracted from the participant survey questions as well as from the words, phrases, and sentences used by participants during the interview.

    Time frame: Day 1
