Brief Summary

This study aims to enhance workplace safety by implementing a firearm safety program at Penn Medicine Pennsylvania Hospital (PAH). The option to store firearms securely during visits is offered to firearm owners. The study focuses on understanding barriers and facilitators to this program and piloting methods to collect data on firearm storage device use. The approach prioritizes participant confidentiality and pragmatism. The study design involves iterative pilot testing of data collection methods and comparison of acceptance and usage rates between cable locks and lock boxes through randomization. The intended outcome is to provide evidence supporting the scalability and effectiveness of the program. The study population includes patients and visitors who accept firearm safety materials or express interest in receiving a firearm storage device. The primary outcome measure is survey response rate, with secondary outcomes including firearm storage behavior and likelihood of using a gun safety device. Additionally, the study explores variations in survey distribution methods.

Gun Violence Prevention

Outcome Measures

Primary Outcomes (1)

• Survey Response Rate

  The primary outcome measure is survey response rate, defined as whether an eligible visitor or patient completed the firearm storage survey after accepting firearm safety materials or after scanning the QR code on the study poster.

  From 2 to 4 weeks

Secondary Outcomes (2)

• Rate of Full Firearm Storage at Follow-Up

  From 2 to 4 weeks

• Likelihood of Using Cable Lock Within the Next Week (Extremely Unlikely to Extremely Likely Scale).

  From 2 to 4 weeks

Study Arms (2)

Individual receives cable lock as default

EXPERIMENTAL

Participants in this arm are either automatically assigned due to taking a cable lock at the hospital when offered AND fill out the survey OR are randomized into this group by filling out the study survey linked in study materials.

Behavioral: Received cable lock as default

Individual has a choice between cable lock and lock box

EXPERIMENTAL

Participants in this arm are randomized into it based on NOT taking a cable lock at the hospital when offered AND fill out the survey OR are randomized into this group by filling out the study survey linked in study materials.

Behavioral: Choice between cable lock or lock box

Interventions

Choice between cable lock or lock box BEHAVIORAL

Participant will have the option to select a lock box or cable lock shipped to their address after filling out the study survey.

Individual has a choice between cable lock and lock box

Received cable lock as default BEHAVIORAL

Participants will receive a cable lock as the default safety device option after filling out the survey. If the participant took a cable lock during their hospital visit and noted this in the survey, they will not be shipped a cable lock. If participants did not take a cable lock and noted this in the survey, they will be shipped a cable lock.

Individual receives cable lock as default

• Any patient or visitor interested in receiving a firearm storage device who self-selects into the study by scanning the QR code on the study poster; OR
• Any individual interested in receiving a firearm storage device who clicks the link to the survey posted on the Penn Medicine Safety Measures website that is included health system appointment reminders.

You may not qualify if:

• Individuals who have already completed the survey or have already requested a gun safety device.
