Hearing loss and its impact on residents in long term care facilities: Asystematic review of literature

"We're just winging it". Identifying targets for intervention to improve the provision of hearing support for residents living with dementia in long-term care: an interview study with care staff

PURPOSE

Hearing loss and dementia are common in long-term care home (LTCH) residents, causing communication difficulties and worsened behavioural symptoms. Hearing support provided to residents with dementia requires improvement. This study is the first to use the Behaviour Change Wheel (BCW) to identify barriers and propose interventions to improve the provision of hearing support by LTCH staff.

METHODS

Semi-structured interviews with 10 staff members were conducted. Transcripts were analysed according to the BCW's Theoretical Domains Framework alongside reflective thematic analysis. Relevant intervention functions and exemplar interventions were proposed.

RESULTS

Staff believed hearing support to be beneficial to residents (Beliefs about Consequences) but lacked knowledge of hearing loss management (Knowledge). Poor collaborations between LTCHs and audiology (Environmental Context and Resources), led to despondency, and apprehension about traditional hearing aids for residents (Optimism). Despite feeling responsible for hearing support, staff lacked personal accountability (Social/Professional Role and Identity).

CONCLUSIONS

Future interventions should include staff Training (on hearing support), Education (on the consequences of unsupported hearing loss), Enablement (dementia-friendly hearing devices), Incentivisation and Modelling (of Hearing Champions) and Environmental Restructuring (flexible audiology appointments to take place within the LTCH). Interventions should be multi-faceted to boost the capabilities, opportunities and motivations of LTCH staff.

Capabilities, opportunities and motivations of staff to provide hearing support to long-term care home residents with dementia

OBJECTIVE

Many long-term care home (LTCH) residents have dementia and hearing loss, causing communication difficulties and agitation. Residents rely on staff for hearing support, but provision is often inconsistent. This study used the Behaviour Change Wheel's Capability, Opportunity and Motivation model to understand why LTCH staff do or do not, provide hearing support to residents with dementia who they believe could benefit from it.

DESIGN

An online survey exploring hearing support provision, capabilities, opportunities, motivations and demographics. Data were analysed using descriptive statistics, within-participants ANOVA and multiple linear regression.

STUDY SAMPLE

165 LTCH staff.

RESULTS

Staff provided hearing support to 50% of residents with dementia who they thought would benefit. Self-reported physical and psychological capabilities (skills/knowledge) were significantly higher than physical opportunity (having time/resources). The physical capability was significantly higher than social opportunity (collaborative working) and reflective motivation (feeling motivated). Lower levels of hearing support provision were predicted by LTCH funding (private vs. local authority), job role (care assistant vs. nurse) and fewer physical opportunities.

CONCLUSIONS

Boosting capabilities through training alone may not be as effective as increasing opportunities via environmental restructuring. Opportunities may include strengthening working relationships with audiologists and ensuring hearing and communication aids are available within LTCHs.

"It's Huge, in a Way." Conflicting Stakeholder Priorities for Managing Hearing Impairment for People Living with Dementia in Residential Aged Care Facilities

OBJECTIVES

The aims of this study were to a) explore the impact of hearing impairment on people living with dementia in residential aged care facilities (RACFs) and b) investigate management of hearing impairment for this population.

METHODS

A descriptive qualitative approach, consisting of semi-structured interviews, was conducted with 23 participants across four stakeholder groups (audiologists, care staff, family members and individuals with dementia and hearing impairment living in RACFs).

RESULTS

Thematic analysis revealed an overarching theme of "different priorities for managing hearing impairment" that emerged from the data. Audiologists and care staff prioritized different practices for managing hearing impairment: audiologists emphasized hearing aids and care staff emphasized communication strategies. Care staff also identified that current management of hearing impairment was sub-optimal as they do not prioritize managing it.

CONCLUSIONS

Residents with dementia and hearing impairment living in RACFs are not receiving optimal hearing management. Further research is required to understand the factors that influence this.

CLINICAL IMPLICATIONS

Changes in practices of both care staff and audiologists are required to improve hearing impairment management for this population.

Barriers and facilitators of appropriate antibiotic use in primary care institutions after an antibiotic quality improvement program - a nested qualitative study

BACKGROUND

Antibiotic prescribing by physicians in primary care institutions is common and affected by several factors. Diagnosis and treatment of infections in a nursing home (NH) resident is challenging, with the risk of both under- and overtreatment. Identifying barriers and facilitators of appropriate antibiotic prescribing in NHs and municipal acute care units (MACUs) is essential to ensure the most adequate antibiotic treatment possible and develop future antibiotic stewardship programs.

METHODS

After implementing a one-year antibiotic quality improvement program, we conducted six semi-structured focus group interviews with physicians (n = 11) and nurses (n = 14) in 10 NHs and 3 MACUs located in the county of Østfold, Norway. We used a semi-structured interview guide covering multiple areas influencing antibiotic use to identify persistent barriers and facilitators of appropriate antibiotic prescribing after the intervention. The interviews were audio-recorded and transcribed verbatim. The content analysis was performed following the six phases of thematic analysis developed by Braun and Clarke.

RESULTS

We identified thirteen themes containing barriers and facilitators of the appropriateness of antibiotic use in primary care institutions. The themes were grouped into four main levels: Barriers and facilitators 1) at the clinical level, 2) at the resident level, 3) at the next of kin level, and 4) at the organisational level. Unclear clinical presentation of symptoms and lack of diagnostic possibilities were described as essential barriers to appropriate antibiotic use. At the same time, increased availability of the permanent nursing home physician and early and frequent dialogue with the residents' next of kin were emphasized as facilitators of appropriate antibiotic use. The influence of nurses in the decision-making process regarding infection diagnostics and treatment was by both professions described as profound.

CONCLUSIONS

Our qualitative study identified four main levels containing several barriers and facilitators of appropriate antibiotic prescribing in Norwegian NHs and MACUs. Diagnostic uncertainty, frequent dialogue with next of kin and organisational factors should be targeted in future antibiotic stewardship programs in primary care institutions. In addition, for such programs to be as effective as possible, nurses should be included on equal terms with physicians.

Analysis of the Knowledge, Attitudes, and Practice Model of Healthcare Professionals on Hearing Loss at Elderly Dementia Residences in Korea

Due to a lack of knowledge about age-related hearing loss, its early identification and appropriate intervention are not being carried out in the field of dementia care. Since the untreated hearing loss of the elderly leads to a more rapid cognitive decline, the present study aimed to understand the hearing-related knowledge, attitudes, and practices of healthcare professionals in long-term care (LTC) facilities in Korea. A total of 557 workers (104 facility managers and 453 healthcare professionals) in residential LTC participated in this cross-sectional multicenter survey study. The Korean version of the knowledge, attitudes, and practice (KAP) on-line survey with a five-point scale or yes/no response was applied as the experimental tool. The results of structural equation modeling showed that knowledge significantly affected the attitudes and health-seeking practices of the facility manager, and allied healthcare professionals demonstrated similar results, which showed the significant effects of that knowledge on attitudes and health-seeking practices. This clearly indicated that sufficient knowledge is the driving force for the health-seeking practices and positive attitudes of both the facility manager and the healthcare professionals. Thus, we suggest that a further step, such as the development of comprehensive and professional guidelines regarding hearing care information for these professionals in residential LTC facilities, should be followed, and believe that this effort could lead to improving hearing-related knowledge, attitudes, and practices in order to clinically and politically care for the elderly population.

Cognitive decline, sensory impairment, and the use of audio-visual aids by long-term care facility residents

BACKGROUND

Hearing and vision impairments and the use of audio-visual aids are associated with cognitive decline in community-dwelling older people, but effects in long-term care facilities (LFCF) are unclear. We hypothesize that visual and hearing impairment are associated with cognitive decline and these relationships are mediated by using visual and hearing aids.

METHODS

Secondary data analysis of a longitudinal study was conducted in the 7 government-subsidized LTCF operated by one of the largest non-governmental organizations in Hong Kong using data between 2005 and 2016. Eligible residents were ≥ 60 years of age without severe cognitive impairment at baseline who had stayed in the facilities for more than 3 years. All variables were measured by using the Minimum Data Set-Resident Assessment Instrument Version 2.0, Hong Kong version. The outcome was cognitive decline. Predictors were visual and hearing impairments. Mediators were the use of visual and hearing aids. General linear models were employed to test the hypotheses.

RESULTS

Results for 2,233 residents were analyzed, with a mean age of 82.1 ± 8.2 years and a mean follow-up period of 4.4 ± 0.8 years. Results showed that those who had visual impairment (p = 0.004) and hearing impairments (p = 0.022) had a higher risk of cognitive decline. Using hearing aids (coefficient = 0.0186, p < 0.05) positively mediates the effect of hearing impairment on cognitive decline. Using visual aids (coefficient = -0.0881, p < 0.05) negatively mediates the effects of visual impairment on cognitive decline.

CONCLUSION

In LTCF, hearing and visual impairments are associated with a higher risk of cognitive decline. Hearing aids often-users were associated with a higher risk of cognitive decline. LTCF residents with visual impairment did not use visual aids. Use of visual aids demonstrated potential effects in slowing cognitive decline. A future study with a larger and more diverse sample with attention to quality of devices is proposed to confirm its effects.

Effectiveness of Hearing Rehabilitation for Care Home Residents With Dementia: A Systematic Review

OBJECTIVES

To report the effectiveness of, and barriers and facilitators to, hearing rehabilitation for care home residents with dementia.

DESIGN

Systematic review.

SETTING AND PARTICIPANTS

Care home residents with dementia and hearing loss.

METHODS

No restrictions on publication date or language were set and gray literature was considered. Eligible studies were critically appraised and presented via a narrative review.

RESULTS

Sixteen studies, most of low to moderate quality, were identified. Hearing rehabilitation, including hearing devices, communication techniques, and visual aids (eg, flashcards), was reported to improve residents' communication and quality of life and reduce agitation, with improvements in staff knowledge of hearing loss and job satisfaction. Residents' symptoms of dementia presented barriers, for example, losing or not tolerating hearing aids. Low staff prioritization of hearing loss due to time pressures and lack of hearing-related training for staff were further barriers, particularly for residents who required assistance with hearing devices. Adopting a person-centered approach based on residents' capabilities and preferences and involving family members facilitated hearing device use.

CONCLUSIONS AND IMPLICATIONS

Residents with dementia can benefit from hearing rehabilitation. Identifying and implementing efficient, individualized hearing rehabilitation is necessary for those with complex cognitive needs. Increased funding and support for the social care sector is required to address systemic issues that pose barriers to hearing rehabilitation, including time pressures, lack of training for staff and access to audiology services for residents.

Hearing and vision health for people with dementia in residential long term care: Knowledge, attitudes and practice in England, South Korea, India, Greece, Indonesia and Australia

OBJECTIVES

Up to 90% of people with dementia in long term care (LTC) have hearing and/or vision impairment. Hearing/vision difficulties are frequently under-recognised or incompletely managed. The impacts of hearing/vision impairment include more rapid cognitive decline, behavioural disturbances, reduced quality of life, and greater care burden. This research investigated LTC staff knowledge, attitudes and practice regarding hearing/vision care needs for residents with dementia.

METHODS

A survey of staff in LTC facilities in England, South Korea, India, Greece, Indonesia and Australia. Respondents used a five-point scale to indicate agreement or YES/NO response to questions regarding sensory-cognitive care knowledge (what is known); attitudes (what is thought); practice (what is done).

RESULTS

Respondents reported high awareness of hearing/vision care needs, although awareness of how to identify hearing/vison difficulties or refer for assessment was low. Most felt that residents were not able to use hearing/vision devices effectively due to poor fit, being poorly tolerated or lost or broken devices. A substantial minority of respondents reported low confidence in supporting use of assistive hearing/vision devices, with lack of training the main reason. Most staff did not undertake routine checking of hearing/vision devices, and it was rare for facilities to have designated staff responsible for sensory needs. Variation among countries was not significant after accounting for staff experience and having received dementia training.

CONCLUSIONS

There is a need to improve sensory support for people with dementia in LTC facilities internationally. Practice guidelines and training to enhance sensory-cognitive knowledge, attitudes and practice in professional care teams is called for.

Inequality in access to hearing care for older adults in residential homes

BACKGROUND

The population of older people in residential homes is projected to rise. There are unrecognized hearing difficulties among residents and prevalence of hearing loss in this population is underreported. This can result in an overestimation of levels of cognitive impairment. Untreated hearing loss is associated with social isolation, depression, disruptive behaviour and cognitive decline. This study aimed to explore the provision of hearing care (hearing assessment, rehabilitation and staff training) in Scottish care homes for older people.

METHODS

A survey comprising 18 questions was distributed to the managers (or designated staff members) of 659 care homes across Scotland.

RESULTS

Responses were obtained from 154 care homes. The results support existing evidence that hearing is not assessed in the majority of homes, resulting in under detection of hearing loss. Staff lack training in supporting residents' hearing needs. Access to hearing care in residential homes differs across health board areas.

CONCLUSIONS

There is an urgent requirement for hearing assessment of older adults on admission to residential care. Care providers require this information to construct effective care plans and mitigate the effects of hearing loss. Those responsible for providing hearing rehabilitation services require information about service users to address any unmet need.

Hearing Screening for Residents in Long-Term Care Homes Who Live with Dementia: A Scoping Review

BACKGROUND

Hearing loss is highly prevalent in older adults, particularly among those living with dementia and residing in long-term care homes (LTCHs). Sensory declines can have deleterious effects on functioning and contribute to frailty, but the hearing needs of residents are often unrecognized or unaddressed.

OBJECTIVE

To identify valid and reliable screening measures that are effective for the identification of hearing loss and are suitable for use by nursing staff providing care to residents with dementia in LTCHs.

METHODS

Electronic databases (Embase, Medline, PsycINFO, CENTRAL, and CINAHL) were searched using comprehensive search strategies, and a stepwise approach based on Arksey & O'Malley's scoping review and appraisal process was followed.

RESULTS

There were 193 scientific papers included in the review. Pure-tone audiometry was the most frequently reported measure to test hearing in older adults living with dementia. However, measures including self- or other-reports and questionnaires, review of medical records, otoscopy, and the whisper test were found to be most suitable for use by nurses working with older adults living with dementia in LTCHs.

CONCLUSION

Although frequently used, the suitability of pure-tone audiometry for use by nursing staff in LTCHs is limited, as standardized audiometry presents challenges for many residents, and specific training is needed to successfully adapt test administration procedures and interpret results. The whisper test was considered to be more suitable for use by staff in LTCH; however, it yields a limited characterization of hearing loss. There remains an urgent need to develop new approaches to screen hearing in LTCHs.

Identifying and Managing Hearing and Vision Loss in Older People in Care Homes: A Scoping Review of the Evidence

BACKGROUND AND OBJECTIVES

Poor identification of sensory impairments in care homes can be due to multiple factors. This scoping review identifies and synthesizes the literature into the detection of hearing and vision loss in the care home environment, and the management of these sensory losses once identified.

RESEARCH DESIGN AND METHODS

A scoping review methodology was used to identify primary research of any design published from 1985 to September 2018. Six electronic databases were searched, and articles were also sourced from reference lists, relevant charity organizations and published experts.

RESULTS

Six electronic databases and multiple gray literature sources identified 51 articles for inclusion. The evidence confirmed that lack of knowledge in care home staff, poor management of assistive aids, unsuitable environment, lack of connections with optometrists and audiologists, underuse of effective screening tools, and the added complexity of assisting those with dementia are all barriers to effective practice. Conversely, flexible training programs, availability of a variety of assistive aids, simple screening tools, and adaptions to the environment are effective facilitators.

DISCUSSION AND IMPLICATION

This review acknowledges that the barriers to identification and management of hearing and vision loss in care homes are multifaceted and that collaboration of multiple stakeholders is required to implement change and improve the residents' ear and eye care. Recommendations are offered to support more effective service provision tailored to meet the needs of people with sensory impairments living in care homes, and this could subsequently improve best practice.

Association of polymorphisms in grainyhead-like-2 gene with the susceptibility to age-related hearing loss: A systematic review and meta-analysis

OBJECTIVE

The grainyhead-like-2 (GRHL2) genetic variants were reported in age-related hearing impairment (ARHI) susceptibility in several case-control studies. However, their conclusions are conflicting; it is difficult to precisely assess the disease risk associated with the variants. Therefore we conduct the meta-analysis to discover the association of GRHL2 polymorphisms and the risk of ARHI.

METHODS

A related literature search was conducted in on-line databases, such as Wanfang database, China National Knowledge Infrastructure (CNKI), EMBASE, Web of Science, and PubMed (updated to August 30, 2018). We use Review Manager 5.0 and Stata SE 12.0 software to reckon the odds radio (OR), 95% confidence interval (CI) and P value in random- or fixed-effects model according to the I2 value in the heterogeneity test.

RESULTS

2762 cases and 2321 controls in 5 articles were provided data to the meta-analysis. The pooled ORs (95% CI) of the rs10955255 polymorphism were 1.26 (1.05-1.50, P = .01), 1.33 (1.07-1.65, P = .01), and 1.32 (1.12-1.55, P = .0007) in the allele, homozygote and recessive model separately. Besides, a significant association was detected between rs1981361 in mixed population and the ARHI risk in the allele, heterozygote, and dominant genetic model respectively. Then subgroup analyses was performed by ethnicity, for rs10955255 meaningful associations were detected for the allele model, homozygote model, dominant model and recessive model in the Caucasian population but no relations in any of the 5 genetic models in Asian population.

CONCLUSION

The meta-analysis indicated that the rs10955255 polymorphism could be an important risk factor for ARHI, especially in the Caucasians. The rs1981361 polymorphism may be a risk factor for ARHI in Asians. Larger scale researches are needed to further bring the consequences up to date.
