Using Gaze Tracking as a Research Tool in the Deaf Health Literacy and Access to Health Information Project: Protocol for a Multisite Mixed Methods Study and Preliminary Results

BACKGROUND

Previous studies have identified the internet as a major source of health information. Reliable and accessible sources of web-based health information are critical for cultivating patient-centered care. However, the accessibility and use of web-based health information remains largely unknown for deaf individuals. We used gaze-tracking technology to understand the navigation and use of web-based health information by deaf adults who communicate with sign language and by hearing adults.

OBJECTIVE

This paper discusses our protocol for implementing gaze-tracking technology in a study that included both deaf and hearing participants. We report the preliminary results and lessons learned from the implementation of the protocol.

METHODS

We conducted gaze-tracking sessions with 450 deaf signers and 450 hearing participants as a part of a larger, multisite mixed methods research study. Then, we conducted qualitative elicitation interviews with a subsample of 21 deaf and 13 hearing participants, who engaged in a search task and reviewed their gaze recordings. To our knowledge, no study has implemented a similar research protocol to better understand the experiences of deaf adults. As such, we also examined research staff notes and observations from team meetings regarding the conduct of gaze-tracking data to delineate lessons learned and best practices for research protocols in this area.

RESULTS

Findings from the implementation of this study protocol highlight the use of gaze technology with deaf participants. We developed additional protocol steps to minimize gaze disruption from either lipreading or communicating in sign language. For example, research assistants were often unable to maintain eye contact with participants while signing because of the need to simultaneously point at the computer monitor to provide instructions related to gaze study components, such as the calibration process. In addition to developing ways to effectively provide instructions in American Sign Language, a practice exercise was included in the gaze tracker session to familiarize participants with the computer and technology. The use of the playback feature permitted a deeper dialogue between researchers and participants, which we found vital for understanding the experiences of deaf participants.

CONCLUSIONS

On the basis of our experience using the study protocol through a large research project, incorporating gaze-tracking technology offers beneficial avenues for better understanding how individuals interact with health information. Gaze tracking can determine the type and placement of visual content that attracts attention from the viewers of diverse backgrounds, including deaf individuals. The lessons learned through this study will help future researchers in determining ideal study designs, such as suitable protocols and participant characteristics (eg, deaf signers), while including gaze trackers in their projects. This approach explored how different ways of presenting health information can affect or enable visual learners to engage and use health information effectively.

Self-reported dual sensory impairment, dementia, and functional limitations in Medicare beneficiaries

BACKGROUND

Vision and hearing impairments often co-exist with dementia, and all are independently associated with limitations in daily activities. Our aim was to examine the association of dual sensory impairment with functional limitations, and further examine the combined estimated association of sensory impairment and dementia with these functional limitations.

METHODS

Cross-sectional analysis of the National Health and Aging Trends Study (NHATS), a population-based cohort of Medicare beneficiaries, was performed. Participants were selected from the 2015 round. Survey weighted Poisson regression models adjusted for dementia, demographics, and health status variables examined the association of self-reported dual sensory impairment (no sensory impairment, single sensory impairment, dual sensory impairment) with scores of limitations in mobility, self-care, and household activities. Models were repeated to take into account the combined effects of dual sensory impairment and dementia.

RESULTS

Overall, 7124 participants representative of Medicare beneficiaries 65 years or older were included. Of them, 43.9% were 75 years or older and 55.3% were female. Older adults with dual sensory impairment had greater limitations with mobility (prevalence rate ratio [PRR] = 1.45, 95% CI = 1.28-1.63), self-care (PRR = 1.41, 95% CI = 1.25-1.59), and household activities (PRR = 1.54, 95% CI = 1.37-1.72) compared with those without sensory impairment. They also had greater limitations than those with a single sensory impairment across the different activity categories. In models taking into account the combined estimated effect of both sensory impairment and dementia, those with dual sensory impairment and dementia had greater limitations than those without sensory impairment or dementia in each category (mobility: PRR = 1.85, 95% CI = 1.59-2.14, self-care: PRR = 1.86, 95% CI = 1.59-2.18, household: PRR = 2.41, 95% CI = 2.09-2.77).

CONCLUSIONS

Older adults with dual sensory impairment had greater functional limitations compared with those without sensory impairment and those with a single sensory impairment. Strategies to improve visual and/or hearing function (e.g., sensory aids, rehabilitation) could potentially help prevent or minimize disability, even among those with dementia.

Implementation of a Hearing Loss Screening Intervention in Primary Care

PURPOSE

Hearing loss (HL) is underdiagnosed and often unaddressed. A recent study of screening for HL using an electronic prompt showed efficacy in increasing appropriate referrals for subsequent testing. We build on the results of this study using a qualitative lens to explore implementation processes through the perspectives of family medicine clinicians.

METHODS

We collected clinic observations and semistructured interviews of family medicine clinicians and residents who interacted with the HL prompt. All data were analyzed using thematic, framework, and mixed methods integration strategies.

RESULTS

We interviewed 27 clinicians and conducted 10 observations. Thematic analysis resulted in 6 themes: (1) the prompt was overwhelmingly viewed as easy, simple to use, accurate; (2) clinicians considered prompt as an effective way to increase awareness and conversations with patients about HL; (3) clinician and staff buy-in played a vital role in implementation; (4) clinicians prioritized prompt during annual visits; (5) medical assistant involvement in prompt workflow varied by health system, clinic, and clinician; (6) prompt resulted in more conversations about HL, but uncertain impact on patient outcomes. Themes are presented alongside constructs of normalization process theory and intervention outcomes.

CONCLUSION

Integration of a HL screening prompt into clinical practice varied by clinician buy-in and beliefs about the impact on patient outcomes, involvement of medical assistants, and prioritization during clinical visits. Further research is needed to understand how to leverage clinician and staff buy-in and whether implementation of a new clinical prompt has sustained impact on HL screening and patient outcomes.

Community-Engaged Needs Assessment of Deaf American Sign Language Users in Florida, 2018

OBJECTIVES

Deaf American Sign Language (ASL) users comprise a linguistic and cultural minority group that is understudied and underserved in health education and health care research. We examined differences in health risk behaviors, concerns, and access to health care among Deaf ASL users and hearing English speakers living in Florida.

METHODS

We applied community-engaged research methods to develop and administer the first linguistically accessible and contextually tailored community health needs assessment to Deaf ASL users living in Florida. Deaf ASL users (n = 92) were recruited during a 3-month period in summer 2018 and compared with a subset of data on hearing English speakers from the 2018 Florida Behavioral Risk Factor Surveillance System (n = 12 589). We explored prevalence and adjusted odds of health behavior, including substance use and health care use.

RESULTS

Mental health was the top health concern among Deaf participants; 15.5% of participants screened as likely having a depressive disorder. Deaf people were 1.8 times more likely than hearing people to engage in binge drinking during the past month. In addition, 37.2% of participants reported being denied an interpreter in a medical facility in the past 12 months.

CONCLUSION

This study highlights the need to work with Deaf ASL users to develop context-specific health education and health promotion activities tailored to their linguistic and cultural needs and ensure that they receive accessible health care and health education.

Pregnancy and Neonatal Outcomes Among Deaf or Hard of Hearing Women: Results From Nationally Representative Data

BACKGROUND

Although the literature suggests that women with disabilities are at increased risk for pregnancy complications and adverse birth outcomes, there are few population-based studies of the pregnancy outcomes among deaf and hard of hearing (DHH) women in the United States.

OBJECTIVE

To compare pregnancy complications and neonatal outcomes between deliveries to DHH and non-DHH women using national hospitalization discharge record data.

STUDY DESIGN

We used the 2007-2016 Healthcare Cost and Utilization Project National Inpatient Sample to compare pregnancy complications and outcomes among deliveries to DHH women with deliveries to non-DHH women using bivariate and Poisson regressions, controlling for sociodemographic, hospital, and clinical characteristics.

RESULTS

DHH women had an increased risk of adverse pregnancy outcomes and chronic medical conditions, including preexisting diabetes (relative risk [RR], 2.01; 95% confidence interval, 1.68-2.42; p < .001), gestational diabetes (RR, 1.31; 95% CI, 1.19-1.44; p < .001), chronic hypertension (RR, 1.51; 95% CI, 1.33-1.72; p < .001), preeclampsia and eclampsia (RR, 1.35; 95% CI, 1.21-1.51; p < .01), placenta previa (RR, 1.62; 95% CI, 1.22-2.16; p < .01), placental abruption (RR, 1.43; 95% confidence interval, 1.15-1.78; p < .01), labor induction (RR, 1.16; 95% CI, 1.05-1.27; p < .01), chorioamnionitis (RR, 1.43; 95% CI, 1.22-1.69; p < .001), cesarean delivery (RR, 1.09; 95% CI, 1.04-1.14; p < .001), premature rupture of membranes (RR, 1.34; 95% CI, 1.20-1.50; p < .001), antepartum hemorrhage (RR, 1.36; 95% CI, 1.13-1.64; p < .001), and postpartum hemorrhage (RR, 1.30; 95% CI, 1.13-1.49; p < .001). After adjustment for socioeconomic and hospital characteristics, the risk for gestational diabetes, preeclampsia and eclampsia, placenta previa, and chorioamnionitis remained unexplained.

CONCLUSIONS

DHH women are at an increased risk for adverse pregnancy, fetal, and neonatal outcomes, illuminating the need for awareness among obstetric and primary care providers as well as the need for systematic investigation of outcomes and evidence-based guidelines.

Hearing Loss and Healthcare Access among Adults

Hearing loss (HL) is common among individuals aged 50 and older and is associated with increased healthcare costs. Whether HL is associated with less access to healthcare is unclear. In this study, we examined the association between HL and access to medical care and prescription drugs among individuals 50+ with and without HL. We used nationally representative 2013-2014 Medical Expenditure Panel Survey data, consisting of 1,977 adults with HL and 17,399 without. We applied an inverse propensity score weighting and regression modeling to adjust for any potential differences in health and socioeconomic conditions between the two groups. Adults with HL were more likely to be white, less educated, poorer, and with public insurance ( p  < 0.001). They were also likely to have hypertension, heart disease, stroke, emphysema, high cholesterol, diabetes, joint pain, and arthritis ( p  < 0.001). The odds of reporting unmet medical needs (odds ratio [OR] = 1.85; 95% confidence interval [CI] = 1.29-2.66), delay in getting medical needs met (OR = 1.37; 95% CI = 1.00-1.87), and having unfilled prescriptions (OR = 1.81; 95% CI = 1.27-2.59) were higher among individuals with HL compared with their counterparts without HL. Individuals with HL have less access to care and prescription drugs. To ensure equitability in access, public health policies should address specific needs of people with HL.

Prevalence of Concurrent Functional Vision and Hearing Impairment and Association With Dementia in Community-Dwelling Medicare Beneficiaries

IMPORTANCE

Impairments in vision or hearing are common and have been independently linked to higher risk of dementia in older adults. There is a limited understanding of the prevalence of concurrent functional vision and hearing impairment (dual sensory impairment) and its contribution to dementia risk.

OBJECTIVE

To examine the age-specific prevalence of functional dual sensory impairment among older adults, and to investigate the cross-sectional and 7-year longitudinal associations between functional dual sensory impairment and dementia.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study of 7562 older adults used data from the US National Health and Aging Trends Study (NHATS), a nationally representative cohort study of community-dwelling, Medicare beneficiaries aged 65 years and older in the US. Participants in the study with complete data on hearing, vision, and dementia were included in analysis. Data were collected between 2011 and 2018, and between March 2018 and May 2020.

EXPOSURES

Self-reported functional sensory impairments (ie, no sensory impairment, functional vision impairment only, functional hearing impairment only, and functional dual sensory impairment).

MAIN OUTCOMES AND MEASURES

Age-specific prevalence of functional sensory impairments was calculated. Generalized linear regression with a complementary log-log link and a discrete time proportional hazards model with a complementary log-log link were used to assess the cross-sectional and 7-year longitudinal hazard of dementia.

RESULTS

Of 7562 participants, 3073 (40.7%) were ages 80 years or older and 4411 (58.3%) were women. Overall, 5.4% (95% CI, 4.7%-6.1%) of participants reported functional vision impairment only, 18.9% (95% CI, 18.9%-17.8%) reported functional hearing impairment only, and 3.1% (95% CI, 2.7%-3.5%) reported functional dual sensory impairment (prevalence estimates are weighted). Participants reporting sensory impairments were older (no impairment: age ≥90 years, 2.12% [95% CI, 1.79%-2.46%] vs functional dual sensory impairment: age ≥90 years, 20.06% [95% CI, 16.02%-24.10%]), had lower education (no impairment: <high school, 19.05% [95% CI, 17.27%-20.83%] vs functional dual sensory impairment: <high school, 46.15% [95% CI, 38.38%-53.92%]), and greater disease burden (eg, heart disease: no impairment, 15.30% [95% CI, 14.04%-16.55%] vs functional dual sensory impairment, 25.49% [95% CI, 19.96%-31.02%]). Compared with no impairment, functional vision impairment (adjusted hazard ratio [aHR], 1.89; 95% CI, 1.57-2.28), functional hearing impairment (aHR, 1.14; 95% CI, 1.00-1.31), and functional dual sensory impairment (aHR, 2.00; 95% CI, 1.57-2.53) were associated with a higher cross-sectional hazard of dementia. Over 7 years, functional vision impairment (aHR, 1.40; 95% CI, 1.12-1.74), functional hearing impairment (aHR, 1.09; 95% CI, 0.95-1.24), and functional dual sensory impairment (aHR, 1.50; 95% CI, 1.12-2.02) were associated with a higher hazard of incident dementia compared with no impairment.

CONCLUSIONS AND RELEVANCE

In this cohort study of US Medicare beneficiaries, dual sensory impairment was prevalent in older adults and associated with increased risk of dementia. These findings suggest that sensory rehabilitative interventions for multiple impairments may be an additional resource in efforts to reduce dementia risk.

Effective Hearing Loss Screening in Primary Care: The Early Auditory Referral-Primary Care Study

PURPOSE

Hearing loss, the second most common disability in the United States, is under-diagnosed and under-treated. Identifying it in early stages could prevent its known substantial adverse outcomes.

METHODS

A multiple baseline design was implemented to assess a screening paradigm for identifying and referring patients aged ≥55 years with hearing loss at 10 family medicine clinics in 2 health systems. Patients completed a consent form and the Hearing Handicap Inventory for the Elderly (HHI). An electronic alert prompted clinicians to screen for hearing loss during visits.

RESULTS

The 14,877 eligible patients during the study period had 36,701 encounters. Referral rates in the family medicine clinics increased from a baseline rate of 3.2% to 14.4% in 1 health system and from a baseline rate of 0.7% to 4.7% in the other. A general medicine comparison group showed referral rate increase from the 3.0% baseline rate to 3.3%. Of the 5,883 study patients who completed the HHI 25.2% (n=1,484) had HHI scores suggestive of hearing loss; those patients had higher referral rates, 28% vs 9.2% (P <.001). Of 1,660 patients referred for hearing testing, 717 had audiology data available for analysis: 669 (93.3%) were rated appropriately referred and 421 (58.7%) were considered hearing aid candidates. Overall, 71.5% of patients contacted felt their referral was appropriate.

CONCLUSION

An electronic alert used to remind clinicians to ask patients aged ≥55 years about hearing loss significantly increased audiology referrals for at-risk patients. Audiologic and audiogram data support the effectiveness of the prompt. Clinicians should consider adopting this method to identify patients with hearing loss to reduce its known and adverse sequelae.

Determinants of Hearing Aid Use Among Older Americans With Hearing Loss

BACKGROUND AND OBJECTIVES

Hearing loss (HL) is common among older adults and is associated with significant psychosocial, cognitive, and physical sequelae. Hearing aids (HA) can help, but not all individuals with HL use them. This study examines how social determinants may impact HA use.

RESEARCH DESIGN AND METHODS

We conducted an explanatory sequential mixed methods study involving a secondary analysis of a nationally representative data set, the Health and Retirement Study (HRS; n = 35,572). This was followed up with 1:1 qualitative interviews (n = 21) with community participants to clarify our findings. Both samples included individuals aged 55 and older with a self-reported HL, with or without HA. The main outcome measure was the proportion of participants with a self-reported HL who use HA.

RESULTS AND DISCUSSION

Analysis of HRS data indicated that younger, nonwhite, non-Hispanic, lower income, and less-educated individuals were significantly less likely to use HA than their referent groups (all p values < .001). Area of residence (e.g., urban) were not significantly associated with HA use. Qualitative findings revealed barriers to HA included cost, stigma, vanity, and a general low priority placed on addressing HL by health care providers. Facilitators to obtaining and using HA included family/friend support, knowledge, and adequate insurance coverage for HA.

IMPLICATIONS

Many socioeconomic factors hinder individuals' ability to obtain and use HA, but these obstacles appeared to be mitigated in part when insurance plans provided adequate HA coverage, or when their family/friends provided encouragement to use HA.

Pregnancy, Birth, and Infant Outcomes Among Women Who Are Deaf or Hard of Hearing

INTRODUCTION

Being deaf or hard of hearing can be marginalizing and associated with inequitable health outcomes. Until recently, there were no U.S. population-based studies of pregnancy outcomes among deaf or hard of hearing women. In light of inconsistent findings in the limited available literature, this study sought to conduct a more rigorous study using population-based, longitudinal linked data to compare pregnancy complications, birth characteristics, and neonatal outcomes between deaf or hard of hearing and non-deaf or hard of hearing women.

METHODS

Researchers conducted a retrospective cohort study in 2019 using the Massachusetts Pregnancy to Early Life Longitudinal data system. This system links all Massachusetts birth certificates, fetal death reports, and delivery- and nondelivery-related hospital discharge records for all infants and their mothers. The study included women with singleton deliveries who gave birth in Massachusetts between January 1998 and December 2013.

RESULTS

The deaf or hard of hearing women had an increased risk of chronic medical conditions and pregnancy complications including pre-existing diabetes, gestational diabetes, pre-eclampsia and eclampsia, and placental abruption. Deliveries to deaf or hard of hearing women were significantly associated with adverse birth outcomes, including preterm birth, low birth weight or very low weight, and low 1-minute Apgar score or low 5-minute Apgar score. No significant differences were found in size for gestational age, fetal distress, or stillbirth among deaf or hard of hearing women.

CONCLUSIONS

Findings from this 2019 study indicate that deaf or hard of hearing women are at a heightened risk for chronic conditions, pregnancy-related complications, and adverse birth outcomes and underscore the need for systematic investigation of the pregnancy- and neonatal-related risks, complications, costs, mechanisms, and outcomes of deaf or hard of hearing women.

Deaf Adults' Health Literacy and Access to Health Information: Protocol for a Multicenter Mixed Methods Study

Background

Deaf American Sign Language (ASL) users often struggle with limited health literacy compared with their hearing peers. However, the mechanisms driving limited health literacy and how this may impact access to and understanding of health information for Deaf individuals have not been determined. Deaf individuals are more likely than hearing individuals to use the internet, yet they continue to report significant barriers to health information. This study presents an opportunity to identify key targets that impact information access for a largely marginalized population.

Objective

This study aims to elucidate the role of information marginalization on health literacy in Deaf ASL users and to better understand the mechanisms of health literacy in this population for the purpose of identifying viable targets for future health literacy interventions.

Methods

This is an exploratory mixed methods study to identify predictors and moderators of health literacy in the Deaf population. These predictors of health literacy will be used to inform the second step that qualitatively explains the findings, including how Deaf individuals access and understand Web-based health information. Multiple interviewer- and computer-based instruments underwent translation and adaptation, from English to ASL, to make them accessible for the Deaf participants in our study. A planned sample of 450 Deaf ASL users and 450 hearing native English speakers, aged 18 to 70 years, will be recruited from 3 partnering sites: Rochester, NY; Flint, MI; and Chicago, IL. These individuals will participate in a single data collection visit. A subset of participants (approximately 30) with key characteristics of interest will be invited for a second data collection visit to observe and inquire more about their ability to directly access, navigate, and comprehend Web-based health information. The study will help assess how the ways health literacy and information are visualized may differ between Deaf individuals and hearing individuals. The study will also survey participants’ ownership and use of computer and mobile devices and their level of Web-based information use, including health information.

Results

Adaptation and translation of protocols and instruments have been completed and are now in use for the study. Recruitment is underway and will continue until late 2020. Results from this study will be used to provide a guide on how to structure Web-based health information in a way that maximizes accessibility and improves health literacy for Deaf individuals.

Conclusions

The results from this mixed methods proposal will advance what is known about health literacy and health information accessibility for Deaf individuals. This innovative study will generate rich data on how to formulate health information and health literacy interventions more accurately to take advantage of visual learning skills.

Association Between Hearing Aid Use and Health Care Use and Cost Among Older Adults With Hearing Loss

Importance

Hearing loss (HL) is common among older adults and is associated with poorer health and impeded communication. Hearing aids (HAs), while helpful in addressing some of the outcomes of HL, are not covered by Medicare.

Objective

To determine whether HA use is associated with health care costs and utilization in older adults.

Design, Setting, and Participants

This retrospective cohort study used nationally representative 2013-2014 Medical Expenditure Panel Survey data to evaluate the use of HAs among 1336 adults aged 65 years or older with HL. An inverse propensity score weighting was applied to adjust for potential selection bias between older adults with and without HAs, all of whom reported having HL. The mean treatment outcomes of HA use on health care utilization and costs were estimated.

Exposures

Encounter with the US health care system.

Main Outcomes and Measures

(1) Total health care, Medicare, and out-of-pocket spending; (2) any emergency department (ED), inpatient, and office visit; and (3) number of ED visits, nights in hospital, and office visits.

Results

Of the 1336 individuals included in the study, 574 (43.0%) were women; mean (SD) age was 77 (7) years. Adults without HAs (n = 734) were less educated, had lower income, and were more likely to be from minority subpopulations. The mean treatment outcomes of using HAs per participant were (1) higher total annual health care spending by $1125 (95% CI, $1114 to $1137) and higher out-of-pocket spending by $325 (95% CI, $322 to $326) but lower Medicare spending by $71 (95% CI, -$81 to -$62); (2) lower probability of any ED visit by 2 percentage points (PPs) (24% vs 26%; 95% CI, -2% to -2%) and lower probability of any hospitalization by 2 PPs (20% vs 22%; 95% CI, -3% to -1%) but higher probability of any office visit by 4 PPs (96% vs 92%; 95% CI, 4% to 4%); and (3) 1.40 more office visits (95% CI, 1.39 to 1.41) but 0.46 (5%) fewer number of hospital nights (95% CI, -0.47 to -0.44), with no association with the number of ED visits, if any (95% CI, 0.01 to 0).

Conclusions and Relevance

This study demonstrates the beneficial outcomes of use of HAs in reducing the probability of any ED visits and any hospitalizations and in reducing the number of nights in the hospital. Although use of HAs reduced total Medicare costs, it significantly increased total and out-of-pocket health care spending. This information may have implications for Medicare regarding covering HAs for patients with HL.

Can Hearing Aids Delay Time to Diagnosis of Dementia, Depression, or Falls in Older Adults?

OBJECTIVE

To examine the association between hearing aids (HAs) and time to diagnosis of Alzheimer disease (AD) or dementia, anxiety or depression, and injurious falls among adults, aged 66 years and older, within 3 years of hearing loss (HL) diagnosis.

DESIGN

Retrospective cohort study.

SETTING

We used 2008 to 2016 national longitudinal claims data (based on office visit, inpatient, or outpatient healthcare encounters) from a large private payer. We used Kaplan-Meier curves to examine unadjusted disease-free survival and crude and adjusted Cox regression models to examine associations between HAs and time to diagnosis of three age-related/HL-associated conditions within 3 years of HL diagnosis. All models were adjusted for age, sex, race/ethnicity, census divisions, and prior diagnosis of cardiovascular conditions, hypertension, hypercholesterolemia, obesity, and diabetes.

PARTICIPANTS

The participants included 114 862 adults, aged 66 years and older, diagnosed with HL.

MEASUREMENT

Diagnosis of (1) AD or dementia; (2) depression or anxiety; and (3) injurious falls.

INTERVENTION

Use of HAs.

RESULTS

Large sex and racial/ethnic differences exist in HA use. Approximately 11.3% of women vs 13.3% of men used HAs (95% confidence interval [CI] difference = -0.024 to -0.016). Approximately 13.6% of whites (95% CI = 0.13-0.14) vs 9.8% of blacks (95% CI = 0.09-0.11) and 6.5% of Hispanics (95% CI = 0.06-0.07) used HAs. The risk-adjusted hazard ratios of being diagnosed with AD/dementia, anxiety/depression, and injurious falls within 3 years after HL diagnosis, for those who used HAs vs those who did not, were 0.82 (95% CI = 0.76-0.89), 0.89 (95% CI = 0.86-0.93), and 0.87 (95% CI = 0.80-0.95), respectively.

CONCLUSIONS

Use of HAs is associated with delayed diagnosis of AD, dementia, depression, anxiety, and injurious falls among older adults with HL. Although we have shown an association between use of HAs and reduced risk of physical and mental decline, randomized trials are needed to determine whether, and to what extent, the relationship is causal.

The Relationship Between Hearing Loss and Substance Use Disorders Among Adults in the U.S

INTRODUCTION

Hearing loss is common and associated with poorer health and impeded communication. Little is known about the association between hearing loss and substance use disorders in the general population. The objective of this study was to assess substance use disorder prevalence among individuals with hearing loss, versus those without hearing loss, in a nationally representative sample of adults.

METHODS

Two years (2015 and 2016) of National Survey on Drug Use and Health (unweighted N=86,186) were combined to compare substance use disorders among adults with and without self-reported hearing loss. Statistical analysis included descriptive frequencies, chi-square tests, and multiple logistic regressions. Analyses were performed in 2018.

RESULTS

Hearing loss prevalence across all age groups was 5.2%. Among younger age groups, after adjusting for sociodemographics, hearing loss was independently associated with an increased likelihood of experiencing a substance use disorder (ages 18-34 years, AOR=1.34, 95% CI=1.10, 1.64 vs 35-49 years, AOR=1.87, 95% CI=1.39, 2.53). Hearing loss was also associated with a greater likelihood of a prescription opioid use disorder (AOR=2.85, 95% CI=1.86, 4.39) in the group aged 18-34 years and, for the group aged 35-49 years, hearing loss increased the likelihood of both an alcohol use disorder (AOR=1.87, 95% CI=1.39, 2.53) and a prescription opioid use disorder (AOR=1.99, 95% CI=1.01, 3.91).

CONCLUSIONS

Hearing loss is independently associated with substance use disorders among those aged 49 years and younger; these associations are particularly pronounced for prescription opioid use disorders in the group aged 18-34 years. Given the concern of inappropriate use of prescription opioids, this information may have implications for healthcare providers' pain management for patients with hearing loss.

Initial Results of the Early Auditory Referral-Primary Care (EAR-PC) Study

INTRODUCTION

Hearing loss (HL) is the second most common disability in the U.S., yet is clinically underdiagnosed. To manage its common adverse psychosocial and cognitive outcomes, early identification of HL must be improved.

METHODS

A feasibility study conducted to increase screening for HL and referral of patients aged ≥55 years arriving at two family medicine clinics. Eligible patients were asked to complete a self-administered consent form and the Hearing Handicap Inventory (HHI). Independently, clinicians received a brief educational program after which an electronic clinical prompt (intervention) alerted them (blinded to HHI results) to screen for HL during applicable patient visits. Pre- and post-intervention differences were analyzed to assess the proportion of patients referred to audiology and those diagnosed with HL (primary outcomes) and the audiology referral appropriateness (secondary outcome). Referral rates for those who screened positive for HL on the HHI were compared with those who scored negatively.

RESULTS

There were 5,520 eligible patients during the study period, of which 1,236 (22.4%) consented. After the intervention's implementation, audiology referral rates increased from 1.2% to 7.1% (p<0.001). Overall, 293 consented patients (24%) completed the HHI and scored >10, indicating probable HL. Of these 293 patients, 28.0% were referred to audiology versus only 7.4% with scores <10 (p<0.001). Forty-two of the 54 referred patients seen by audiology were diagnosed with HL (78%). Overall, the diagnosis of HL on problem lists increased from 90 of 4,815 patients (1.9%) at baseline to 163 of 5,520 patients (3.0%, p<0.001) over only 8 months.

CONCLUSIONS

The electronic clinical prompt significantly increased audiology referrals for at-risk patients for HL in two family medicine clinics. Larger-scale studies are needed to address the U.S. Preventive Services Task Force call to assess the long-term impact of HL screening in community populations.

Use of Reversible Contraceptive Methods Among U.S. Women with Physical or Sensory Disabilities

CONTEXT

Women with disabilities experience a higher rate of adverse pregnancy outcomes than women without disabilities. Preventing or delaying pregnancy when that is the best choice for a woman is a critical strategy to reducing pregnancy-related disparities, yet little is known about current contraceptive use among women with disabilities.

METHODS

A cohort of 545 reproductive-age women with physical disabilities (i.e., difficulty walking, climbing, dressing or bathing) or sensory disabilities (i.e., difficulty with vision or hearing) was identified from among participants in the 2011-2013 National Survey of Family Growth. Those at risk for unplanned pregnancy were categorized by whether they were using highly effective reversible contraceptive methods (IUD, implant), moderately effective ones (pill, patch, ring, injectable), less effective ones (condoms, withdrawal, spermicides, diaphragm, natural family planning) or no method. Multinomial regression was conducted to examine the association between disability and type of contraceptive used.

RESULTS

Some 39% of women with disabilities were at risk of unplanned pregnancy, and 27% of those at risk were not using contraceptives. The presence of disability was associated with decreased odds of using highly effective methods or moderately effective methods, rather than less effective ones (odds ratio, 0.6 for each), but had no association with using no method.

CONCLUSION

There is a significant need to reduce contraceptive disparities related to physical or sensory disabilities. Future research should explore the extent to which contraceptive use differs by type and severity of disability, as well as identify contextual factors that contribute to any identified differences.

Hearing loss and associated medical conditions among individuals 65 years and older

BACKGROUND

Hearing loss is prevalent, but few studies have investigated its associations with common medical conditions.

OBJECTIVE

The objective was to assess the prevalence of medical conditions among individuals with hearing loss, compared to those without hearing loss, in people aged 65 years and older.

METHODS

The National Health Interview Survey (NHIS) collects data on a variety of health-related topics, including disability. Three years of NHIS data (2011-2013; unweighted n = 53,111) were pooled to examine subpopulations of individuals with hearing loss. Comparisons were made between adults aged 65 and older with, and without, self-reported hearing loss. Statistical analysis included descriptive frequencies, Chi-square tests, and multiple logistic regressions. The outcomes of interest included self-reported diagnosis of arthritis, cardiovascular disease, diabetes, high blood pressure, emphysema, stroke, cancer, asthma, multiple chronic conditions, health status, and obesity.

RESULTS

Hearing loss prevalence was nearly 37%. After adjusting for sociodemographics, smoking status, and disability, hearing loss was independently associated with the following conditions: arthritis (OR 1.41; 1.27-1.57), cancer (OR 1.35; 1.21-1.5), cardiovascular disease (OR 1.48; 1.33-1.66), diabetes (OR 1.16; 1.03-1.31), emphysema (OR 1.41; 1.14-1.74), high blood pressure (OR 1.29; 1.17-1.43), and stroke (OR 1.39; 1.12-1.66). There was an association with worse health status over the past year (OR 1.5 (1.3-1.73).

CONCLUSIONS

Hearing loss among older individuals is independently associated with increased disease burden and poorer self-reported health. Future studies are needed to investigate the mechanistic nature of these associations, and whether improved access to hearing healthcare surveillance can reduce the overall health burden among these individuals.

Hearing Loss: Communicating With the Patient Who Is Deaf or Hard of Hearing

Hearing loss impairs health care communication and adversely affects patient satisfaction, treatment adherence, and use of health services. Hearing loss is the third most common chronic health condition among older patients after hypertension and arthritis, but only 15% to 18% of older adults are screened for hearing loss during health maintenance examinations. Patients with hearing loss may be reluctant to disclose it because of fear of ageism, perceptions of disability, and vanity. Lipreading and note writing often are ineffective ways to communicate with deaf and hard of hearing (DHH) patients who use American Sign Language; use of medical sign language interpreters is preferred. A variety of strategies can improve the quality of health care communication for DHH patients, such as the physician facing the patient, listening attentively, and using visual tools. Physicians should learn what hearing loss means to the DHH patient. Deaf American Sign Language users may not perceive hearing loss as a disability but as a cultural identity. Patients' preferred communication strategies will vary. Relay services, electronic communication, and other telecommunications methods can be helpful, but family physicians and medical staff should learn from each DHH patient about which communication strategies will work best.

Hearing Loss: Hearing Augmentation

Etiologies of hearing loss vary. When hearing loss is diagnosed, referral to an otology subspecialist, audiology subspecialist, or hearing aid dispenser to discuss treatment options is appropriate. Conventional hearing aids provide increased sound pressure in the ear canal for detection of sounds that might otherwise be soft or inaudible. Hearing aids can be used for sensorineural, conductive, or mixed hearing loss by patients with a wide range of hearing loss severity. The most common type of hearing loss is high-frequency, which affects audibility and perception of speech consonants, but not vowels. As the severity of hearing loss increases, the benefit of hearing aids for speech perception decreases. Implantable devices such as cochlear implants, middle ear implants, and bone-anchored implants can benefit specific patient groups. Hearing assistive technology devices provide auditory, visual, or tactile information to augment hearing and increase environmental awareness of sounds. Hearing assistive devices include wireless assistive listening device systems, closed captioning, hearing aid-compatible telephones, and other devices. For some patients, financial barriers and health insurance issues limit acquisition of hearing aids, implantable devices, and hearing assistive devices. Physicians should be aware that for some patients and families, hearing augmentation may not be desired for cultural reasons.

Hearing Loss: Diagnosis and Evaluation

Hearing loss is a common disability in the United States, most frequent among men, elderly individuals, and veterans but is increasingly affecting other younger adults. Types of hearing loss include sensorineural, conductive, and mixed. Hearing loss in children often is related to infections, time spent in a neonatal intensive care unit, and genetic etiologies. Presbycusis (ie, age-related hearing loss) is the most common etiology in adults. Adverse effects of untreated hearing loss include isolation, depression, lower income, and higher unemployment. Hearing aid use reduces levels of disability, cognitive impairment, and psychosocial distress while improving quality of life. At least 75% of individuals with hearing loss are not receiving treatment for it. All infants should be screened for hearing loss, as should children and adults with risk factors. The Joint Commission on Infant Hearing Screening has a 1-3-6 goal for screening: identification by age 1 month, confirmation by age 3 months, and intervention by age 6 months. The presence of an ongoing physician-patient relationship increases the likelihood that a patient will admit to having a hearing loss. Adults can be screened using single-question or standardized instrument screens. All patients with suspected hearing loss should undergo audiometry by an audiology subspecialist.

Hearing Loss: Issues in the Deaf and Hard of Hearing Communities

Hearing loss can lead to impairments in language and speech acquisition, educational attainment, social development, and reading achievement. More than 90% of deaf and hard of hearing (DHH) children are born to hearing parents who may lack the knowledge or experience to effectively care for a child with hearing loss. Family involvement is crucial for teaching self-advocacy and global communication skills, optimizing social development, and helping DHH individuals understand and manage external attitudes about deafness and hearing loss. American Sign Language is a naturally developed language with an always-expanding lexicon and grammatical structures different from those of English. Teaching spoken English and American Sign Language equally, often called bilingual bimodal education, can enhance academic and reading achievement as well as language and psychosocial development. Formal schooling options for a DHH child include enrollment in a public or private school system (often called inclusion, integration, or mainstreaming), a school for the deaf, or a bilingual school. Individuals with hearing loss experience stereotypes and biases that create disparities in health insurance coverage, health care access, and outcomes of mental and physical conditions. Family physicians should recognize and minimize biases to improve health care in the DHH community.
