Prevalence and risk factors of hearing loss among the middle-aged and older population in China: a systematic review and meta-analysis

PURPOSE

This paper was aimed at estimating the prevalence and risk factors of hearing loss (HL) among the middle-aged and elderly in China.

METHODS

Databases including the CQVIP (VIP) Database, Chinese National Knowledge Infrastructure (CNKI), China Biology Medicine disc (CBMdisc), Wanfang, PubMed, Web of Science, Excerpta Medica Database (Embase) and the Cochrane Library were comprehensively searched. In this review, random-effect models were used for pooling the prevalence of HL and the odds ratios (ORs) of potential risk factors.

RESULTS

34 studies were included in the meta-analysis. HL among the middle-aged and elderly in China had a pooled prevalence of 45% (95% confidence interval (CI) 40-51%). There were significant differences in the prevalence of HL between males and females (47% vs. 42%), between different screening methods by self-report and pure-tone audiometry (44% vs. 46%), between the middle-aged and the elderly (18% vs. 52%), and between the uneducated and the educated (49% vs. 36%). In urban areas, the prevalence was slightly higher than that in rural areas (50% vs. 48%). The findings suggested that the middle-aged and elderly in the South Central China region (61%, 95% CI 45-78%) and Northwest China (57%, 95% CI 55-58%) were more likely to develop HL. In addition, it was confirmed that advanced age, being male, noise exposure history, hypertension and hyperglycemia were related to a higher prevalence of HL among middle-aged and older adults.

CONCLUSION

The prevalence of HL among the middle-aged and older population in China is 45%, nearly half of the total population. It is urgent to take great efforts to raise people's awareness of HL prevention and early hearing screening.

Hearing screening and amplifier uptake results in a multidisciplinary head and neck cancer survivorship clinic

PURPOSE

Hearing loss and tinnitus are prevalent among survivors of head and neck cancer (HNC), but auditory issues are under-addressed in the survivorship literature. The purpose of this study was to describe the hearing loss and management experience of a group of survivors provided with a hearing screening and amplifier assistance if needed during their visit.

METHODS

A retrospective chart review of 1176 individuals seen in the HNC Survivorship Clinic between December 2016 and October 2020 who interacted with audiology was performed.

RESULTS

Of these survivors, 72% failed the 30-dB HL hearing screening at one or more frequencies. Thirty-three percent of the sample reported tinnitus. Consistent with the general population, this group has a low prevalence of hearing aid use. In this clinic, individuals who fail the hearing screening at all frequencies are offered a simple, non-custom amplifier for use during their visit. Thirty-one percent of individuals offered the amplifier used it during their Survivorship Clinic visit to enhance communication and reduce listening effort. Only 54% of individuals who failed the hearing screening self-reported hearing loss. The poor sensitivity and specificity associated with the self-perception of hearing loss data support the need for hearing screening that consists of responding to tones. Of individuals who received a recommendation for a comprehensive hearing test, 21% received a hearing test with 68% of these individuals receiving the hearing test the same day of their Survivorship Clinic visit.

CONCLUSIONS

The data from 1176 survivors of HNC seen by audiology over the past few years as part of the UPMC HNC Survivorship Clinic support the need for hearing management in this population to improve communication during and after the Survivorship Clinic visit.

IMPLICATIONS FOR CANCER SURVIVORS

Survivors of HNC have a high prevalence of greater than mild hearing loss and tinnitus (both issues known to negatively impact health-related communication and quality of life). This manuscript describes a hearing screening program within a Survivorship Clinic that identifies individuals in need of non-custom amplification during their appointment to support effective communication. Survivors should be referred to audiologists for evaluation and management of treatment-related issues of hearing.

Hospital crowdedness evaluation and in-hospital resource allocation based on image recognition technology

How to allocate the existing medical resources reasonably, alleviate hospital congestion and improve the patient experience are problems faced by all hospitals. At present, the combination of artificial intelligence and the medical field is mainly in the field of disease diagnosis, but lacks successful application in medical management. We distinguish each area of the emergency department by the division of medical links. In the spatial dimension, in this study, the waitlist number in real-time is got by processing videos using image recognition via a convolutional neural network. The congestion rate based on psychology and architecture is defined for measuring crowdedness. In the time dimension, diagnosis time and time-consuming after diagnosis are calculated from visit records. Factors related to congestion are analyzed. A total of 4717 visit records from the emergency department and 1130 videos from five areas are collected in the study. Of these, the waiting list of the pediatric waiting area is the largest, including 10,436 (person-time) people, and its average congestion rate is 2.75, which is the highest in all areas. The utilization rate of pharmacy is low, with an average of only 3.8 people using it at the one time. Its average congestion rate is only 0.16, and there is obvious space waste. It has been found that the length of diagnosis time and the length of time after diagnosis are related to age, the number of diagnoses and disease type. The most common disease type comes from respiratory problems, accounting for 54.3%. This emergency department has congestion and waste of medical resources. People can use artificial intelligence to investigate the congestion in hospitals effectively. Using artificial intelligence methods and traditional statistics methods can lead to better research on healthcare resource allocation issues in hospitals.

Providing Hearing Assistance to Veterans in the Emergency Department: A Qualitative Study

INTRODUCTION

Effective communication is essential to good health care, and hearing loss disrupts patient-provider communication. For the more than 2 million veterans with severe hearing loss, communication is particularly challenging in noisy health care environments such as emergency departments. The purpose of this qualitative study was to describe patient and provider perspectives of feasibility and potential benefit of providing a hearing assistance device, a personal amplifier, during visits to an emergency department in an urban setting affiliated with the Department of Veterans Affairs.

METHODS

This qualitative descriptive study was conducted in parallel with a randomized controlled study. We completed a semistructured interview with 11 veterans and 10 health care providers to elicit their previous experiences with patient-provider communication in the ED setting and their perspectives on hearing screening and using the personal amplifier in the emergency department. Interview data were analyzed using content analysis and Atlas.ti V8.4 software (Scientific Software Development GmbH, Berlin, Germany).

RESULTS

The veteran sample (n = 11) had a mean age of 80.3 years (SD = 10.2). The provider sample included 7 nurses and 3 physicians. In the ED setting, hearing loss disrupts patient-provider communication. Screening for hearing loss in the emergency department was feasible except in urgent/emergent cases. The use of the personal amplifier made communication more effective and less effortful for both veterans and providers.

DISCUSSION

Providing the personal amplifier improved the ED experience for veterans and offers a promising intervention that could improve health care quality and safety for ED patient populations.

Conversations in Cochlear Implantation: The Inner Ear Therapy of Today

As biomolecular approaches for hearing restoration in profound sensorineural hearing loss evolve, they will be applied in conjunction with or instead of cochlear implants. An understanding of the current state-of-the-art of this technology, including its advantages, disadvantages, and its potential for delivering and interacting with biomolecular hearing restoration approaches, is helpful for designing modern hearing-restoration strategies. Cochlear implants (CI) have evolved over the last four decades to restore hearing more effectively, in more people, with diverse indications. This evolution has been driven by advances in technology, surgery, and healthcare delivery. Here, we offer a practical treatise on the state of cochlear implantation directed towards developing the next generation of inner ear therapeutics. We aim to capture and distill conversations ongoing in CI research, development, and clinical management. In this review, we discuss successes and physiological constraints of hearing with an implant, common surgical approaches and electrode arrays, new indications and outcome measures for implantation, and barriers to CI utilization. Additionally, we compare cochlear implantation with biomolecular and pharmacological approaches, consider strategies to combine these approaches, and identify unmet medical needs with cochlear implants. The strengths and weaknesses of modern implantation highlighted here can mark opportunities for continued progress or improvement in the design and delivery of the next generation of inner ear therapeutics.

Accuracy of self- and proxy-rated hearing among older adults with and without cognitive impairment

BACKGROUND

Hearing loss is highly prevalent among older adults with cognitive impairment and may exacerbate neuropsychiatric symptoms and affect interactions with others. Although audiometry is the gold standard for measuring hearing, it is not always used in research or clinical settings focused on the care of individuals with cognitive impairment. Subjective assessments of hearing, both self- and proxy-rated, are widespread but may not adequately capture the presence of hearing loss as compared to audiometry. This study investigates the concordance between subjective and objective hearing assessments among older adults with and without cognitive impairment and evaluates factors associated with concordance.

METHODS

Participants were a subset of the Atherosclerosis Risk in Communities Neurocognitive Study (ARIC-NCS), a prospective cohort study representing four US communities with adjudicated cognitive diagnoses and audiometric data, totaling 3326 self-rated and 520 proxy-rated hearing assessments. Sensitivity and specificity were calculated, and multivariable logistic regression estimated the magnitude of the association between the concordance of hearing assessments and variables of interest.

RESULTS

Sensitivity and specificity for self-rated hearing status were 71.2% and 85.9% among cognitively normal older adults, 61.1% and 84.9% among persons with MCI, and 52.6% and 81.2% among persons with dementia, respectively. For proxy-rated hearing, sensitivity and specificity were 65.7% and 83.3% for persons with MCI and 73.3% and 60.3% for persons with dementia, respectively. Female sex was positively associated with concordance for self-rated hearing assessments.

CONCLUSIONS

The low sensitivity of self- and proxy-rated hearing assessments compared to audiometry suggests that hearing loss among older adults with cognitive impairment may go underreported and unaddressed in subjective assessments. Clinicians and researchers should recognize the limitations of using self- and proxy-rated hearing assessments as measures of hearing status and incorporate objective audiometric evaluation whenever possible.

Evidence-Based Communication with Critically Ill Older Adults

Communication is a critical component of patient-centered care. Critically ill, mechanically ventilated patients are unable to speak and this condition is frightening, frustrating, and stressful. Impaired communication in the intensive care unit (ICU) contributes to poor symptom identification and restricts effective patient engagement. Older adults are at higher risk for communication impairments in the ICU because of pre-illness communication disorders and cognitive dysfunction that often accompanies or precedes critical illness. Assessing communication disorders and developing patient-centered strategies to enhance communication can lessen communication difficulty and increase patient satisfaction.
