A Usability Assessment of Naloxone Administration by Untrained Community Members

This will be a randomized, open-label, usability assessment of intramuscular, intranasal, and nasal spray administration of naloxone using two different instruction sets by laypersons. * Design: Single site, open-label, randomized usability assessment of intramuscular, intranasal, and nasal spray administration of simulated naloxone. A convenience sample of participants will consent to volunteer in the study at a public venue. Participants will provide verbal consent and will be randomly assigned a simulated naloxone kit containing either intramuscular, intranasal, or nasal spray administration materials with either standard or study team designed instructions for use. Participants will enter a use scenario station and be asked to assemble and administer the simulated naloxone kit to a mannequin (intranasal and nasal spray) or simulated flesh pad (intramuscular). The participant will be instructed to start and will be timed until the simulated naloxone has been successfully administered or 7 minutes has elapsed. The participant will be observed by one trained investigator who will assess for successful administration of the simulated naloxone and critical errors. The environment will contain distractors.Once the participant has successfully administered simulated naloxone or 7 minutes elapses the timer will be stopped. Successful administration of simulated naloxone will be defined as administration of the agent without any critical errors occurring (defined below). Data collected will include demographics (defined below), successful administration of simulated naloxone, time to successful administration of simulated naloxone, and Likert-item data assessing the ease of use of the device and instructions. * Participants: adults (18 years of age and older) at a public venue will be asked to volunteer. Participants with severe visual or hearing impairment (defined as: legally deaf, legally blind, unable to read print size provided on instructional handout, or unable t
