Hearing Loss Prevention for Veterans

2014-08-27 03:17:05 | BioPortfolio

Summary

Hearing loss is the most prevalent service-connected disability in the VA. It causes communication difficulties, which contribute to isolation, frustration and depression. A major cause of hearing loss is from exposure to high levels of sound, and is referred to as Noise Induced Hearing Loss (NIHL). Veterans have inevitably been exposed to high levels of sound during military service, and even though they may not yet have NIHL, their ears have been damaged. Continued noise exposure in civilian life will result in NIHL. However, it can easily be prevented by avoiding noise or using hearing protection. Most people are unaware that noise damages hearing, and even when they are, they do not use hearing protection. In this study we will use a randomized controlled trial to evaluate the short- and long-term effectiveness of two forms of education about NIHL that we have developed for Veterans. One is a computerized program; the other is a Hearing Conservation Brochure

Description

Hearing loss and tinnitus are the two most prevalent service-connected disabilities in the VA system for OEF/OIF Veterans, and Veterans from World War II, Korea, Vietnam, the Gulf War and during Peacetime. Costs associated with health care utilization, provision of hearing aids, rehabilitation services and reduced productivity for Veterans with hearing loss are substantial, and continue to increase. On a personal level, hearing loss results in communication difficulties, and often contributes to social isolation, frustration and depression. A major cause of hearing impairment is cochlear damage from exposure to high levels of sound. The longer the period of exposure and the more intense the sound pressure level, the greater is the damage that occurs. The damage from noise exposure is cumulative over time, and exacerbates the effects of aging. Veterans, who have been exposed to high levels of sound in the military are therefore highly vulnerable to damage in civilian life, thus they must protect their ears from further noise to avoid hearing loss as they age. Unfortunately, most people are unaware of the damage noise can do to the auditory system, and even when they are aware, few choose to use hearing protection. It is therefore critical to educate Veterans about the dangers of noise exposure and the simple actions that can be taken to protect hearing.

Our long-range goal is to disseminate an effective hearing loss prevention education program that will help to reduce the prevalence and associated costs of noise induced hearing loss in the Veteran population. Ultimately it is our intention to make the program available to all Veterans, military personnel and other members of the public.

We have developed two forms of intervention to educate Veterans about hearing conservation. One is a computerized multimedia interactive program; the other is a printed Hearing Conservation Brochure. Both provide information about hearing, the damage noise can do to the auditory system, the impact hearing loss has on communication, and the use of hearing protection. In this study we will use a randomized controlled trial to evaluate the effectiveness of these two forms of intervention at changing knowledge, attitudes and behaviors toward hearing conservation. Effectiveness will be examined in three ways through assessment of: (1) actual behavioral changes, as evidenced by decreased daily noise exposure as measured with noise dosimetry; (2) reported behavioral changes, as evidenced by decreased daily noise exposure assessed using a real-time log of daily activities and use of hearing protection; and (3) increased knowledge, healthier attitudes and improved intended and actual behavior towards hearing protection, as assessed with a self-report questionnaire. Outcomes will be measured at baseline, immediately following the intervention and six month post-intervention.

There are many challenges facing military personnel as they reintegrate into society after leaving military service. Reducing their risk of acquiring noise induced hearing loss and the associated problems with communication, will help to make this transition less difficult and traumatic. This study will provide important information about the relative effectiveness of two different forms of hearing conservation education. In the long term it has the potential to reduce the prevalence and associated costs of hearing loss and tinnitus among Veterans, and will demonstrate that prevention of hearing loss can reduce the need for long-term rehabilitation.

Medical and Biotech [MESH] Definitions

Hearing loss due to exposure to explosive loud noise or chronic exposure to sound level greater than 85 dB. The hearing loss is often in the frequency range 4000-6000 hertz.

Hearing loss due to disease of the AUDITORY PATHWAYS (in the CENTRAL NERVOUS SYSTEM) which originate in the COCHLEAR NUCLEI of the PONS and then ascend bilaterally to the MIDBRAIN, the THALAMUS, and then the AUDITORY CORTEX in the TEMPORAL LOBE. Bilateral lesions of the auditory pathways are usually required to cause central hearing loss. Cortical deafness refers to loss of hearing due to bilateral auditory cortex lesions. Unilateral BRAIN STEM lesions involving the cochlear nuclei may result in unilateral hearing loss.

Hearing loss due to damage or impairment of both the conductive elements (HEARING LOSS, CONDUCTIVE) and the sensorineural elements (HEARING LOSS, SENSORINEURAL) of the ear.

Hearing loss without a physical basis. Often observed in patients with psychological or behavioral disorders.

Hearing loss in frequencies above 1000 hertz.
