Challenges and successes in recruiting firefighters for hearing loss prevention research

Noise-induced hearing loss (NIHL) is a significant occupational health problem in the United States, affecting more than 1 million firefighters. Noise hazards include vehicles, sirens, and power tools. Additionally, firefighters are commonly exposed to ototoxic chemicals. Because the use of hearing protection is not universally required for firefighters, firefighters must be educated about NIHL to ensure they take personal responsibility for hearing loss prevention. This study discusses challenges associated with recruiting firefighters to participate in a randomized, controlled trial testing a web-based hearing protection training program. Successful recruitment strategies included collaboration with key stakeholders, a flexible and convenient computer-based intervention, expansion to multiple recruitment sites, and interactive outreach to potential participants. Future research should use quantitative methods to evaluate and compare the effectiveness of specific recruitment strategies to facilitate firefighter enrollment in research studies. Developing and testing effective hearing protection interventions for firefighters is a crucial first step toward preventing NIHL in this population.
