IMPORTANCE
Utility is a single-value, preference-based measure of health-related quality of life that represents the desirability of a health state relative to being dead or in perfect health. Clinical, funding, and policy decisions rely on measured changes in utility. The benefit of hearing loss treatments may be underestimated because existing utility measures fail to capture important changes in quality of life associated with hearing loss.
OBJECTIVE
To develop a comprehensive profile of items that describe how quality of life is associated with hearing loss and its treatments that can be used to generate hearing-related quality of life measures, including a novel utility measure.
DESIGN, SETTING, AND PARTICIPANTS
This qualitative study, performed from August 1, 2018, to August 1, 2019, in tertiary referral centers, comprised a systematic literature review, focus groups, and semistructured interviews. The systematic review evaluated studies published from 1982 to August 1, 2018. Focus groups included 8 clinical experts experienced in the measurement, diagnosis, treatment, and rehabilitation of hearing loss. Semistructured interviews included 26 adults with hearing loss recruited from an institutional data set and outpatient hearing aid and otology clinics using stratified convenience sampling to include individuals of diverse ages, urban and rural residency, causes of hearing loss, severity of hearing loss, and treatment experience.
MAIN OUTCOMES AND MEASURES
A set of items and subdomains that collectively describe the association of hearing loss with health-related quality of life.
RESULTS
The literature search yielded 2779 articles from the MEDLINE, Embase, Cochrane, PsycINFO, and CINAHL databases. Forty-five studies including 1036 individuals (age range, 18-84 years) were included. The focus group included 4 audiologists and 4 otologists. Hour-long semistructured interviews were conducted with 26 individuals (13 women; median age, 54 years; range, 25-83 years) with a broad range of hearing loss causes, configurations, and severities. From all 3 sources, a total of 125 items were generated and organized into 29 subdomains derived from the World Health Organization's International Classification of Functioning, Disability and Health.
CONCLUSIONS AND RELEVANCE
The association of hearing loss with quality of life is multidimensional and includes subdomains that are not considered in the estimation of health utility by existing utility measures. The presented comprehensive profile of items can be used to generate or evaluate measures of hearing-related quality of life, including utility measures.

BACKGROUND
Literature suggests that risk factors for middle ear pathologies, such as traumatic injuries and human immunodeficiency virus (HIV), exist in mines. However, studies on hearing health in mines seem to focus primarily on occupational noise-induced hearing loss and ignore middle ear pathologies. As a result, there is little documented evidence on the trends of middle ear pathologies in mine workers.
OBJECTIVES
The aim of this study was to explore and document published evidence reflecting trends in middle ear pathologies in mine workers.
METHOD
A systematic literature review of studies that reported middle ear pathologies in mine workers was conducted. Medline, CINAHL, PubMed, PsychInfo and Google Scholar databases were searched for studies in English published between January 1994 and December 2018 and reporting on trends in middle ear pathologies in mine workers.
RESULTS
Two research studies met the selection criteria and were included for analysis. One research study used tympanometry with 226 Hz probe tone, while another study used interviews to determine the presence of middle ear pathologies. While these studies indicate that middle ear pathologies exist in individuals working in mines, the evidence is limited.
CONCLUSION
While current data indicate that individuals working in mines may present with middle ear pathologies of varying severities, the evidence is too small to provide a clear trend of middle ear pathologies in individuals working in mines. Therefore, the current limited data suggest a need for further studies to examine middle ear pathologies in individuals working in mines.

BACKGROUND AND OBJECTIVES
The knowledge and perception of teleaudiology among audiologists will determine the acceptance and success of teleaudiology practice. This systematic review was conducted to review the published literature on knowledge and perceptions of teleaudiology application among audiologists.
MATERIALS AND METHODS
Five studies exploring knowledge and perceptions of teleaudiology application among audiologists published in the English language up to May 2017 were included.
RESULTS
Positive attitudes was observed across the studies regarding acceptance towards application of teleaudiology. The most common sources of knowledge were on the job, graduate studies, and continuing education programs. The major barriers to the uptake of application of teleaudiology were in terms of limitations in infrastructure, reimbursement, and licensure.
CONCLUSIONS
The study sheds light on the existing knowledge and perceptions of teleaudiology applications among audiologists. This will help in improving the existing teleaudiology services as well as overcome the challenges faced.

OBJECTIVES
Define clinical trials and adverse event (AE) monitoring from the perspective of the audiologist. Rationalise the importance of audiology's involvement before, during and after monitoring. Identify strengths and weaknesses in toxicity grading scales, and discuss factors that may influence these.
DESIGN
Literature involving commonly cited grading scales used to capture ototoxicity is reviewed. Current regulations and language associated with clinical trial implementation and AE monitoring are described. Personal observations based on a variety of clinical populations are drawn from years of experience developing and employing ototoxicity monitoring protocols in a complex medical setting.
RESULTS
Six commonly used grading scales for ototoxicity are systematically reviewed for strengths and weaknesses. Necessary considerations that inform selection of grading scales are presented. A review of and historical context for clinical trial development and AE monitoring is provided.
CONCLUSIONS
The audiologist's role in therapeutic decision making goes beyond collection of the audiogram. Clear communication to stakeholders in ototoxicity monitoring is paramount, and toxicity grading scales are one tool to facilitate this exchange. Various factors should be considered in advance of selecting the most appropriate scale to capture hearing loss, and no scale is without limitation.

Review
INTRODUCTION
The literature reports on high-frequency audiometry as one of the exams used on hearing monitoring of individuals exposed to high sound pressure in their work environment, due to the method́s greater sensitivity in early identification of hearing loss caused by noise. The frequencies that compose the exam are generally between 9 KHz and 20KHz, depending on the equipment.
OBJECTIVE
This study aims to perform a retrospective and secondary systematic revision of publications on high-frequency audiometry on hearing monitoring of individuals exposed to occupational noise.
DATA SYNTHESIS
This systematic revision followed the methodology proposed in the Cochrane Handbook, focusing on the question: "Is High-frequency Audiometry more sensitive than Conventional Audiometry in the screening of early hearing loss individuals exposed to occupational noise?" The search was based on PubMed data, Base, Web of Science (Capes), Biblioteca Virtual em Saúde (BVS), and in the references cited in identified and selected articles. The search resulted in 6059 articles in total. Of these, only six studies were compatible with the criteria proposed in this study.
CONCLUSION
The performed meta-analysis does not definitively answer the study's proposed question. It indicates that the 16 KHz high frequency audiometry (HFA) frequency is sensitive in early identification of hearing loss in the control group (medium difference (MD = 8.33)), as well as the 4 KHz frequency (CA), this one being a little less expressive (MD = 5.72). Thus, others studies are necessary to confirm the HFA importance for the early screening of hearing loss on individuals exposed to noise at the workplace.
