This is the final report of the American Academy of Audiology Task Force on the Health-Related Quality of Life (HRQoL) Benefits of Amplification in Adults. A systematic review with meta-analysis examined evidence pertaining to the use of hearing aids for improving HRQoL for adults with sensorineural hearing loss (SNHL). Relevant search strings applied to the CENTRAL, CINAHL, Cochrane Reviews, ComDisDome, EBMR, and PubMed databases identified randomized controlled trial, quasi-experimental, and nonexperimental pre-post test designed studies. Sixteen studies met a priori criteria for inclusion in this review. A random-effects meta-analysis showed differential results for generic versus disease-specific HRQoL measures for within- and between-subject designs. Although generic measures used for within-subject designs did not demonstrate HRQoL benefits from hearing aids, mean effect sizes and confidence intervals for within-subject designs and disease-specific instruments suggested that hearing aids have a small-to-medium impact on HRQoL. Further, the between-subject studies supported at least a small effect for generic measures, and when measured by disease-specific instruments, hearing aids had medium-to-large effects on adults' HRQoL. This review concludes that hearing aids improve adults' HRQoL by reducing psychological, social, and emotional effects of SNHL. Future studies should include control groups using randomized controlled trials.
Most of these college students should not be at great risk of hearing loss from their iPods when used conscientiously. Some concern is warranted for a small segment of these students who seemed to be most at risk because they listened to their iPods at high volume levels for long durations using earbuds, and reported that they may already have hearing loss due to their iPods.
Hearing and balance problems are prevalent among the elderly. Primary care physicians (PCPs) are important pivotal points of entry for ensuring that patients receive needed audiology services. New Medicare beneficiaries are entitled to one-time preventative examinations including hearing/balance screenings. A 35-item questionnaire was developed to assess physicians' participation in, knowledge about, and attitudes toward hearing/balance screenings and referrals for the elderly. The survey was mailed to 710 PCPs (19 undeliverable; 95 returned; response rate = 13.7%) in major metropolitan areas in the United States. Generally, these PCPs were not conducting hearing/balance screenings, aware of patient self-report screening questionnaires, or likely to screen in the future. They referred to audiologists and otolaryngologists mainly when patients complained of having hearing/balance difficulties, and they stated that these problems were important in the elderly and that the Medicare program was worthy of funding but that they had little time and were not reimbursed appropriately for screening. Therefore, PCPs could benefit from informational outreach campaigns on the prevalence of, negative HRQoL (health-related quality of life) effects from, and screening procedures for hearing/balance disorders in the elderly.
Evidence exists supporting the notion that adults with MSNHL benefit from hearing aids. This information is important and useful to audiologists, patients, and third-party payers, even considering that most of the studies in this systematic review were limited, somewhat dated, and used analog and early digital technology available when the studies were conducted. Clinical recommendations may be even stronger as future studies become available for patients fit with modern styles and high-technology hearing aids.
Follow-up rates for babies identified for hearing loss from early hearing detection and intervention programs (EHDIPs) and newborn hearing screening programs (NHSPs) in the United States do not meet the goals posited by the Centers for Disease Control. Pediatric otolaryngologists (PED-ENTs) play a vital role in EHDIPs and can positively influence parents' compliance with professionals' recommendations for their babies. This national study used a 19-item questionnaire and postal survey to assess PED-ENTs' knowledge about, experience with, and attitudes toward NHSPs. Of 565 surveys mailed (36 were undeliverable), 233 were returned for a 44% response rate. Most of these PED-ENTs had adequate knowledge about, participated in, and expressed positive attitudes toward NHSPs; however, some could benefit from additional information about national EHDI benchmarks and poor follow-up rates. Audiologists should ally with PED-ENTs locally and nationally to strengthen EHDIPs and prevent loss of children with hearing impairment to follow-up.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
