Using Implementation Science to Improve the Adoption of Hearing Protector Fit Testing in the Department of Defense

Area of Science:

• Occupational Health
• Implementation Science
• Audiology

Background:

• The Department of Defense (DoD) Hearing Conservation Program aims to prevent hearing loss.
• Department of Defense Instruction (DoDI) 6055.12 mandates quantitative hearing protector fit testing (HPFT).
• Despite being an evidence-based practice, HPFT adoption has been limited.

Purpose of the Study:

• To apply Implementation Science to understand challenges in adopting HPFT within the DoD.
• To identify barriers and facilitators to HPFT implementation.
• To inform the development of effective HPFT training materials.

Main Methods:

• A mixed-methods approach was employed.
• Semi-structured interviews and course evaluation surveys were conducted.
• Data gathered assessed determinants influencing HPFT training implementation.

Main Results:

• Key barriers included determining personal attenuation rating, system connectivity, data access, space, time, procurement, stakeholder buy-in, and electronic health record integration.
• Facilitators comprised evidence strength, ease of use, leadership support, and patient satisfaction.
• Training materials were refined, including new resources and a user-friendly web-based platform.

Conclusions:

• Findings will guide the creation of further training and knowledge products.
• These resources will support providers in implementing new DoDI 6055.12 HPFT requirements.
• Effective training models, including web-based components and practicums, are crucial for HPFT administration.
