The impact of hearing on communication

The clinical use of personal hearing amplifiers in facilitating accessible patient-provider communication: A scoping review

BACKGROUND

Older adults with hearing loss struggle to communicate with care providers and experience higher mortality rates when hospitalized (Genther et al., 2015), even after controlling for age and comorbidities. Personal hearing amplifiers (PHAs), (e.g., Pocketalkers™), can improve communication with older patients.

METHODS

We conducted a scoping review to identify research gaps and summarize findings on the clinical use of PHAs with patients with hearing loss. After refining search terms relating to hearing loss and PHAs, we searched MEDLINE, Embase, PsycINFO, Cochrane Library, CINAHL Complete, Web of Science Core Collection, ERIC (Proquest), PubMed, ClinicalTrials.gov, International Clinical Trials Registry Platform, and the International Standard Randomised Controlled Trial Number Registry. We identified articles published in English between 1980 and 2022 that reported empirical outcomes relating to PHA use in clinical settings. Two reviewers independently extracted data from articles. We then organized data into an evidence map, and a narrative review summarizing outcomes.

RESULTS

From 4234 initially identified titles and abstracts, 12 met our criteria as full texts. These included three surveys on clinicians' awareness and use of PHAs, one evaluation of the acoustic output of a PHA, and eight interventions wherein PHAs were provided to patients with hearing loss. These papers used 10 different terms for PHAs and largely did not cite one another. Results showed high levels of satisfaction with PHAs, and consistently improved speech understanding. Despite this, care providers used devices inconsistently, with challenges around provider awareness, and device maintenance and location tracking.

CONCLUSIONS

PHAs have a consistent positive effect on patients' ability to understand their care providers despite hearing loss. Barriers and facilitators to their use in clinical settings should be further explored.

Hearing Loss: Insights for Home Care Clinicians

Hearing loss is a common problem caused by aging, noise exposure, ototoxic medications, and illness. Given their frequent contact with older adults, home care clinicians are uniquely positioned to recognize the adverse effects of hearing loss on physical, social, and cognitive health. This article explores the factors that contribute to hearing loss, highlighting their cumulative effects on overall hearing ability. The consequences of untreated hearing loss support the urgency of early identification, prompt intervention, and proper management of hearing disability. This article also provides an overview of available treatment options, including traditional prescription hearing aids and recently approved over-the-counter devices. By incorporating components of awareness, treatment, and effective communication strategies, healthcare clinicians can take an integrated approach to improve the overall well-being and quality of life of individuals struggling with hearing loss.

Shared Decision Making for Elective Surgical Procedures in Older Adults with and without Cognitive Insufficiencies

PURPOSE

Older adults are prone to cognitive impairment, which may affect their ability to engage in aspects of shared decision making (SDM) and their ability to complete surveys about the SDM process. This study examined the surgical decision-making processes of older adults with and without cognitive insufficiencies and evaluated the psychometric properties of the SDM Process scale.

METHODS

Eligible patients were 65 y or older and scheduled for a preoperative appointment before elective surgery (e.g., arthroplasty). One week before the visit, staff contacted patients via phone to administer the baseline survey, including the SDM Process scale (range 0-4), SURE scale (top scored), and the Montreal Cognitive Assessment Test version 8.1 BLIND English (MoCA-blind; score range 0-22; scores < 19 indicate cognitive insufficiency). Patients completed a follow-up survey 3 mo after their visit to assess decision regret (top scored) and retest reliability for the SDM Process scale.

RESULTS

Twenty-six percent (127/488) of eligible patients completed the survey; 121 were included in the analytic data set, and 85 provided sufficient follow-up data. Forty percent of patients (n = 49/121) had MoCA-blind scores indicating cognitive insufficiencies. Overall SDM Process scores did not differ by cognitive status (intact cognition x ¯  = 2.5, s = 1.0 v. cognitive insufficiencies x ¯  = 2.5, s = 1.0; P = 0.80). SURE top scores were similar across groups (83% intact cognition v. 90% cognitive insufficiencies; P = 0.43). While patients with intact cognition had less regret, the difference was not statistically significant (92% intact cognition v. 79% cognitive insufficiencies; P = 0.10). SDM Process scores had low missing data and good retest reliability (intraclass correlation coefficient = 0.7).

CONCLUSIONS

Reported SDM, decisional conflict, and decision regret did not differ significantly for patients with and without cognitive insufficiencies. The SDM Process scale was an acceptable, reliable, and valid measure of SDM in patients with and without cognitive insufficiencies.

HIGHLIGHTS

Forty percent of patients 65 y or older who were scheduled for elective surgery had scores indicative of cognitive insufficiencies.Patient-reported shared decision making, decisional conflict, and decision regret did not differ significantly for patients with and without cognitive insufficiencies.The Shared Decision Making Process scale was an acceptable, reliable, and valid measure of shared decision making in patients with and without cognitive insufficiencies.

Study protocol: BRInging the Diabetes prevention program to GEriatric Populations

In the Diabetes Prevention Program (DPP) randomized, controlled clinical trial, participants who were  ≥ 60 years of age in the intensive lifestyle (diet and physical activity) intervention had a 71% reduction in incident diabetes over the 3-year trial. However, few of the 26.4 million American adults age ≥65 years with prediabetes are participating in the National DPP. The BRInging the Diabetes prevention program to GEriatric Populations (BRIDGE) randomized trial compares an in-person DPP program Tailored for Older AdulTs (DPP-TOAT) to a DPP-TOAT delivered via group virtual sessions (V-DPP-TOAT) in a randomized, controlled trial design (N = 230). Eligible patients are recruited through electronic health records (EHRs) and randomized to the DPP-TOAT or V-DPP-TOAT arm. The primary effectiveness outcome is 6-month weight loss and the primary implementation outcome is intervention session attendance with a non-inferiority design. Findings will inform best practices in the delivery of an evidence-based intervention.

Potentially Inadequate Real-Life Speech Levels by Healthcare Professionals during Communication with Older Inpatients

BACKGROUND

The aim of this study was to investigate real-life speech levels of health professionals during communication with older inpatients in small group settings.

METHODS

This is a prospective observational study assessing group interactions between geriatric inpatients and health professionals in a geriatric rehabilitation unit of a tertiary university hospital (Bern, Switzerland). We measured speech levels of health professionals during three typical group interactions (discharge planning meeting (n = 21), chair exercise group (n = 5), and memory training group (n = 5)) with older inpatients. Speech levels were measured using the CESVA LF010 (CESVA instruments s.l.u., Barcelona, Spain). A threshold of <60 dBA was defined as a potentially inadequate speech level.

RESULTS

Overall, mean talk time of recorded sessions was 23.2 (standard deviation 8.3) minutes. The mean proportion of talk time with potentially inadequate speech levels was 61.6% (sd 32.0%). The mean proportion of talk time with potentially inadequate speech levels was significantly higher in chair exercise groups (95.1% (sd 4.6%)) compared to discharge planning meetings (54.8% (sd 32.5%), p = 0.01) and memory training groups (56.3% (sd 25.4%), p = 0.01).

CONCLUSIONS

Our data show that real-life speech level differs between various types of group settings and suggest potentially inadequate speech levels by healthcare professionals requiring further study.

The Intelligibility of the Reversed-Stethoscope Technique in Age-Related Hearing Loss

Background

This study evaluated the effectiveness of the reverse stethoscope technique in improving speech intelligibility. In this technique, a clinician places the earpieces of their stethoscope into the ears of a hearing-impaired patient and speaks into the chest piece.

Methods

The International Speech Test Signal was presented to four Littman® stethoscope models and a Pocketalker® personal voice amplifier using an Audioscan® hearing instrument test box. The acoustic outputs of the stethoscopes and voice amplifier were measured across the frequency spectrum of speech. The Speech Intelligibility Index of the resulting speech was calculated for natural speech and for each device in relation to 10 standardized hearing losses representing the population of older adults.

Results

For each of the 10 hearing losses, the speech signal emitted by the stethoscopes was quieter and yielded lower speech intelligibility scores than regular speech. In contrast, the voice amplifier provided mid- and high-frequency amplification and improved speech intelligibility scores for all but the mildest hearing losses.

Conclusions

The reverse stethoscope technique worsens the clarity of speech and should not be used with older, hearing-impaired patients. Instead, clinicians should use regular speech or, preferably, personal voice amplifiers.

Non-pharmacologic interventions improve comfort and experience among older adults in the Emergency Department

OBJECTIVE

Determine if a comfort cart would improve older adults' comfort and facilitate communication during Emergency Department (ED) visits.

METHODS

A comfort cart containing low-cost, non-pharmacological interventions to improve patient comfort and ability to communicate (e.g., hearing amplifiers, reading glasses) were made available to patients aged ≥65 years. Patients and clinicians were surveyed to assess effectiveness. We followed the Standards for Quality Improvement Reporting Excellence: SQUIRE 2.0 guidelines.

RESULTS

Three hundred patients and 100 providers were surveyed. Among patients, 98.0%, 95.1%, and 67.5% somewhat or strongly agreed that the comfort cart improved comfort, overall experience, and independence, respectively. Among providers, 97.0%, 95.0%, 87.0%, and 83% somewhat or strongly agreed that the comfort cart provided comfort, improved patient satisfaction, increased ability to give compassionate care, and increased patient orientation.

CONCLUSION

The comfort cart was an affordable and effective intervention that improved patients' comfort by facilitating communication, wellbeing, and compassionate care delivery.

Hearing Loss and Risk of Overall, Injury-Related, and Cardiovascular Mortality: The Kangbuk Samsung Health Study

Hearing loss (HL) has been related to cardiovascular risk factors as well as prevalence of cardiovascular disease itself. We evaluated the association of HL with overall, injury-related, and cardiovascular mortality. A cohort study included 580,798 Korean adults (mean age: 39.7) who attended a screening exam between 2002 and 2016 with a follow-up of up to 17 years. HL was defined as a pure-tone average of thresholds at 0.5, 1.0, and 2.0 kHz ≥25 dB (decibels) in the better ear and further categorized into mild (25–<40 dB) and moderate-to-severe (≥40 dB). Overall and cause-specific mortality was ascertained through linkage to national death records. During median follow-up of 8.4 years, 6581 overall deaths, 977 cardiovascular deaths, and 1161 injury-related deaths were identified. Compared to participants with normal hearing, multivariable-adjusted hazard ratios (HRs) with 95% confidence intervals (95% CIs) for overall mortality among participants with mild and moderate-to-severe HL were 1.13 (1.05–1.21) and 1.30 (1.16–1.46), respectively. Corresponding HRs (95% CIs) for cardiovascular mortality were 1.32 (1.10–1.58) and 1.53 (1.16–2.01), respectively, and corresponding HRs (95% CIs) for injury-related mortality were 1.03 (0.81–1.31) and 1.64 (1.13–2.36), respectively. In this large cohort, HL was positively and independently associated with overall, cardiovascular, and injury-related mortality. A significantly elevated risk of cardiovascular mortality started from mild HL.

Self-Reported Hearing/Visual Loss and Mortality in Middle-Aged and Older Adults: Findings From the Komo-Ise Cohort, Japan

Background

The association of sensory loss with mortality remains unclear. We aimed to explore the associations of hearing loss (HL), visual loss (VL), and dual sensory loss (DSL) with survival.

Methods

Data came from the Komo-Ise study cohort in Gunma Prefecture, Japan, where the community-dwelling residents aged 40–69 years were followed up from 1993 to 2010. We analyzed 9,522 individuals who answered the follow-up questionnaires in 2000 (average age 64 [range, 47 to 77] years in 2000). The primary exposures were “HL only,” “VL only,” or “DSL”, with “no HL/VL” as the reference. These sensory loss statuses were assessed by asking the difficulty in hearing conversation or reading newspaper even with aids in the follow-up questionnaires in 2000. All-cause and cause-specific mortality were ascertained from linkage to death certificate data. Cox proportional hazards models adjusting for confounders, including demographic factors, socioeconomic status, and health status, were used. Potential mediators (depression, walking disability, and social participation) were additionally adjusted for.

Results

There were 1,105 deaths over the 10-year follow-up. After adjustment for the potential confounders, HL and DSL were associated with increased all-cause mortality (hazard ratios of 1.74 [95% CI, 1.18–2.57] and 1.63 [95% CI, 1.09–2.42], respectively). Potential mediators explained a modest portion of the association. As for cause-specific mortality, HL was associated with increased cancer mortality, while VL and DSL were associated with increased cardiovascular disease mortality.

Conclusions

Self-reported HL and DSL may be risk factors of mortality among middle-aged or elderly Japanese populations.

Impact of Hearing Loss on Patient–Provider Communication Among Hospitalized Patients: A Systematic Review

Age-related hearing loss is a highly prevalent chronic condition in older adults, but hearing loss is rarely accounted for in patient–provider communication studies. This systematic review synthesizes current evidence on the impact of age-related hearing loss on patient–provider communication in hospitalized older adults. Five databases were queried to identify original research that examined patient–provider communication in older adults with hearing loss in an inpatient setting. Of 1053 studies, 13 were included in the final review. All studies reported an adverse effect of hearing loss on patient–provider communication. Among studies that evaluated an intervention to improve communication in older adults with hearing loss, simple interventions such as low-cost voice amplifiers were found to improve communication. An understanding of the effect of hearing loss on patient–provider communication and strategies to mitigate the impact are needed in order to provide safe, quality, patient-centered care to older adults with hearing loss.

Hearing Loss: Why Does It Matter for Nursing Homes?

Over the past decade, hearing loss has emerged as a key issue for aging and health. We describe why hearing loss may be especially disabling in nursing home settings and provide an estimate of prevalence using the Minimum Data Set (MDS v.3.0). We outline steps to mitigate hearing loss. Many solutions are inexpensive and low-tech, but require significant awareness and institutional commitment.

Hearing and Health Outcomes: Recognizing and Addressing Hearing Loss in Hospitalized Older Adults

As age increases, the prevalence of hearing loss significantly increases, reaching up to 89% of those 80 years and older. Hearing loss in older patients is often unrecognized and its consequences are often underappreciated. Hearing loss can interfere with the ability to exchange important health information and to participate in health care decision-making. Hearing loss during hospitalization increases the risk of misdiagnosis. There is a lack of empirical data regarding prevalence and recognition of hearing loss in hospitalized older adults. In this article, we describe a variety of negative outcomes that may result when older inpatients are functioning with unrecognized hearing loss.

Associations between hearing impairment and mortality risk in older persons: the Blue Mountains Hearing Study

PURPOSE

To assess whether hearing loss predicts an increased risk of mortality.

METHODS

The Blue Mountains Hearing Study examined 2956 persons (49+ years) during 1997 to 2000. The Australian National Death Index was used to identify deaths until 2005. Hearing loss was defined as the pure-tone average (0.5-4 kHz) of air-conduction hearing thresholds greater than 25 dB HL. Associations between hearing loss and mortality risk were estimated using Cox regression and structural equation modeling (SEM).

RESULTS

When we used Cox regression, we discovered that hearing loss was associated with increased risk of cardiovascular (hazard ratio [HR] 1.36, 95% confidence interval [CI] 1.08-1.84) and all-cause (AC) mortality (HR 1.39, 95% CI 1.11-1.79) after adjustment for age and sex but not after multivariable adjustment. SEM pathway analysis, however, revealed a greater AC mortality risk (HR 2.58, 95% CI 1.64-4.05) in persons with hearing loss, which was mediated: cognitive impairment (HR 1.45, 95% CI 1.08-1.94) and walking disability (HR 1.63, 95% CI 1.24-2.15). These variables increased mortality both directly and indirectly through effects on self-rated health.

CONCLUSIONS

Hearing loss was associated with increased AC mortality via three mediating variables: disability in walking, cognitive impairment, and self-rated health. It is important to recognize that persons with combined disabilities are at increased risk of cardiovascular and AC mortality.

Patient and provider perceptions of diabetes: measuring and evaluating differences

OBJECTIVE

This study measures diabetes care perceptions of patients and their providers, and examines perceptions differences of patient-provider pairs.

METHODS

Patient and provider perceptions were assessed using the Diabetes Semantic Differential Scales (DSDS) which ask respondents to rate diabetes care concepts using contrasting adjective pairs. The DSDS was scored by two methods: using means and using factor analysis. Persons with diabetes 40-years-old or older were recruited. Using a "snowball" sampling strategy, potential provider participants were identified by their patients; 71 providers agreed. These providers represented 51% of the patient participants and created 138 patient-provider pairs.

RESULTS

For the mean scores, there were significant differences between patients and providers for 5 of the 18 semantic differentials (28%). Similarly, the factor scores indicated significant differences for 14 of 54 factors (26%). The effect sizes indicated practical differences.

CONCLUSION

Significant differences exist between patient and provider perceptions. Generally, patients have the more positive diabetes perceptions.

PRACTICE IMPLICATIONS

During patient and provider discussions, participants can perceive diabetes concepts differently. The DSDS can determine perception differences. While it is best to use factor analyses to score the DSDS, mean scores are more easily calculated and indicate the broad conceptual areas where patient and provider differ.

Hearing Impairment and Health-Related Quality of Life: The Blue Mountains Hearing Study

OBJECTIVES

To assess the association between hearing impairment and health-related quality of life (HRQOL) in an older population, using the self-administered 36-item Short-Form Health Survey (SF-36).

DESIGN

Participants of the Blue Mountains Hearing Study (BMHS, N = 2956) attended a comprehensive interview and hearing examination in which both self-reported and measured hearing impairments were assessed. Hearing impairment was defined as the pure-tone average of air-conduction hearing thresholds >25 decibels hearing level (dB HL) for the four frequencies (0.5 to 4.0 kHz) in the better ear.

RESULTS

Of the 2431 participants with complete data (mean age, 67.0 yr), 1347 (55.4%) did not have measured hearing loss, whereas 324 (13.3%) had unilateral (285 mild, 22 moderate, 17 severe) and 760 (31.3%) had bilateral hearing impairment (478 mild, 207 moderate, 75 severe). After adjusting for demographic and medical confounders, bilateral hearing impairment was associated with poorer SF-36 scores in both physical and mental domains (fall in physical component score, PCS of 1.4 points, p = 0.025; fall in mental component score, MCS of 1.0 point, p = 0.13), with poorer scores associated with more severe levels of impairment (PCS p(trend) = 0.04, MCS p(trend) = 0.003). Participants with bilateral hearing impairment who habitually used hearing aids had a slightly better PCS (mean, 43.1; standard error [SE], 0.9) than those with the same impairment who did not have hearing aids or who only used them occasionally (mean, 41.2; SE 0.5), although this finding was not statistically significant (p = 0.055). Persons with self-reported hearing loss had significantly poorer HRQOL than corresponding persons without, but persons with unilateral or high-frequency hearing loss did not have significantly different HRQOL scores than their corresponding counterparts.

CONCLUSIONS

This study quantifies the associated disease burden of age-related hearing impairment on health-related quality of life in a population-based cohort of older persons.

Communicating with special populations: children and older adults

Veterinary professionals must meet the growing expectations of a diverse range of clients to sustain success in veterinary medicine. Few veterinarians, however, receive comprehensive skills training for communicating effectively with clients, particularly among special populations, such as children and older adults. An increasing number of veterinary professionals have recognized a need to master requisite skills for effectively interacting with pet-owning families. This article highlights the importance of the human-animal bond for children and older adults, addresses issues of pet loss, and provides suggestions for meeting the communication needs of both populations.

Measuring perceptions of diabetes-related concepts: a preliminary study

PURPOSE

This pilot study explored health professionals' and patients' perceptions of diabetes through the development of the Diabetes Semantic Differential Scales (DSDS). These scales evaluate the meaning of diabetes-related concepts.

METHODS

Health professionals (n = 39) attending a CME course completed the health professional version of the DSDS. Patients (n = 70) completed the patient version of the DSDS.

RESULTS

The reliability of the DSDS was supported. The scale scores of health professionals, African American patients, and Caucasian patients, examined initially by one-way analyses of variance, showed significant differences among the groups for 4 of the 18 diabetes concepts. Effect sizes were also examined among these groups. For 7 concepts, there was a significant practical difference between the perceptions of the health professionals and the African American patients. For the Caucasian patients, differences were noted for 6 concepts.

CONCLUSIONS

There are 3 primary inferences from this pilot study. First, health professionals and patients are likely to hold different perceptions of key diabetes concepts. Second, the concepts on which professionals and patients differ are not always what one would expect. Third, health professionals should clarify patients' understanding of diabetes to minimize the potential for miscommunication.
