Prevalence and determinants of hearing disability among older persons in Malaysia: Finding of National Health Morbidity Survey (NHMS) 2018

AIM

An aging population is a potential burden for unprepared developing countries. Malaysia is foreseen to be an aging country by 2035. Thus, this study aimed to determine the prevalence and factors associated with hearing disability among older persons in Malaysia.

METHODS

Data from a nationwide survey implemented using a stratified cluster sampling design were analyzed. This study was carried out through face-to-face interviews and guided questionnaires. The questions were based on the Washington Group of Disability (WG) questionnaires, which produce multiple disability identifiers. Hearing disability is defined as at least one domain or question out of four questions coded as "A lot of difficulty" or "Cannot hear at all".

RESULTS

The prevalence of hearing disability among older persons aged ≥60 years was 6.4% (95% CI 5.0-8.3), whereas 1.5% (95% CI 0.90, 2.50) older persons were reported to be using a hearing aid. The determinants of hearing disability are being male (aOR 2.67, 95% CI 1.94-3.66), being unemployed (retired, homemaker, unemployed; aOR 1.86, 95% CI 1.86-4.14) and had no formal education (aOR 18.25, 95% CI 4.18-79.55).

CONCLUSIONS

Promoting healthy aging is important and crucial for Malaysia, in preparation toward an aging nation, as it could reduce the country's financial burden in the long term. Health-related agencies should promote health awareness and treatment centers in relation to hearing disability among older persons, as they should be educated and informed about healthcare choices availability, which is aligned with the Global Disability Action Plan 2014-2021.

Prevalence and factors associated with falls among older persons in Malaysia

AIM

Falls are a common problem among older people, leading to major morbidity and increased mortality. The study aimed to determine the prevalence of falls among older persons in Malaysia and its associated factors.

METHODS

Data were obtained from the National Health and Morbidity Survey 2018 (NHMS 2018), a cross-sectional study using stratified cluster sampling design. Older persons were defined as aged ≥60 years in this study. Descriptive and logistic regression analyses were conducted using SPSS version 25.0.

RESULTS

Overall, 14.1% (95% confidence interval [CI]: 12.46, 15.84) of older persons reported having experienced at least one fall during the past 12 months. Univariate analyses revealed an association between the history of falls with not being employed (odds ratio [OR]: 1.35 [95% CI: 1.03, 1.77]), diabetes mellitus (OR: 1.65 [95% CI: 1.33, 2.04]), limitation in activities of daily living (ADL) (OR: 1.90 [95% CI: 1.43, 2.54]) or instrumental ADL (OR: 1.47 [95% CI: 1.16, 1.84]). Multiple logistic regression revealed that falls were positively associated with those who had diabetes mellitus (OR: 1.55 [95% CI: 1.23, 1.94]) and limitation in ADL (OR: 1.56 [95% CI: 1.14, 2.15]); 43.9% of falls occurred outdoors.

CONCLUSION

One in six older Malaysian people experience at least one fall over a 12-month period. Diabetes mellitus and limitation in ADL were the factors associated with falls among older persons. A comprehensive and targeted program designed to reduce risk of falls is urgently needed. Future research should identify suitable programs for our setting to reduce the potential society burden of falls in older Malaysians. Geriatr Gerontol Int 2020; 20: 33-37.

Kidney Function and Cognitive Decline in Older Adults: Examining the Role of Neurodegeneration

BACKGROUND/OBJECTIVES

Cognitive decline associated with impaired kidney function might involve neurodegeneration. Our objectives were to evaluate the longitudinal association between kidney function and cognitive decline in older adults and to assess the involvement of cortical beta-amyloid and hippocampal atrophy (features of Alzheimer's disease (AD)) in this association.

DESIGN

Secondary analysis of the randomized controlled Multidomain Alzheimer Preventive Trial (MAPT).

SETTINGS

Thirteen memory centers (France and Monaco, 2008-2016).

PARTICIPANTS

A total of 1,334 community-dwellers >70 years old without dementia at baseline.

MEASUREMENTS

We estimated glomerular filtration rate (eGFR) from serum creatinine using CKD-Epi equation. Cognition was assessed at baseline, 6, 12, 24, 36, 48, and 60 months using a composite Z-score designed for MAPT. The Clinical Dementia Rating (CDR) score was used to assess cognition and functional independence. We examined the association between eGFR and (1) evolution of the composite cognitive Z-score using mixed-effect models and (2) progression on CDR using Cox models and mixed-effect models. Adjustments were made for age, sex, education, ApoE genotype, cardiovascular risk factors and disease, hippocampal volume (measured with magnetic resonance), and cortical beta-amyloid (measured with positron emission tomography).

RESULTS

Median (IQR) eGFR was 73(60-84) mL/min/1.73 m² . Two hundred sixty-nine participants experienced progression on CDR score during follow-up. eGFR<60 was significantly associated with progression on CDR score (adjusted hazard ratio (aHR) = 1.35, 95% CI 1.01-1.80) and with both the cognitive and functional independence components of CDR, but not with the evolution of the composite cognitive Z-score (adjusted β-coefficient -0.004, 95% CI -0.014; 0.006). Associations were not modified after further adjustment for beta-amyloid (subsample: n = 252) and hippocampal volume (subsample: n = 270).

CONCLUSIONS

We did not find a mild to moderate renal insufficiency to be associated with brain imaging features of AD, and our results do not support the involvement of AD mechanisms in the incidence of cognitive impairment and functional decline associated with chronic kidney disease.

A concept analysis of health communication in a home environment: Perspectives of older persons and their informal caregivers

BACKGROUND

Health communication (HC) is a vast research field focusing on changing health behaviours, and rapidly evolving technology is creating different ways and possibilities to reach target groups and audiences. In the context of home care, a deeper understanding of HC is lacking, specifically for older persons with care needs and their informal caregivers. The aim of this concept analysis is to identify and construct the meaning of HC from the perspective of older persons in need of care in the home environment and their informal caregivers.

MATERIALS AND METHODS

This study utilised Rogers' (2000) Evolutionary Concept Analysis Method (EMCA) to create and construct a meaning of the concept of HC. The EMCA was based on a systematic literature review of scientific articles, using CINAHL, Pubmed and Inspec (2000-2017). A total of 29 articles were retrieved and analysed.

RESULTS

The identified attributes of the concept were as follows: resources of the recipient, influence on decisions and advantages of tailored information. HC was described as both contributing to knowledge as well as being overwhelming where habits and resources influenced the use of information. The attributes led to the following descriptive definition of HC: 'Tailored HC, based on needs and resources of the recipient influence care decisions'. The home environment influenced HC by habits and interactions between older persons and their informal caregivers.

CONCLUSIONS

The home environment influenced HC in terms of social aspects of interactions and habits and between the older person and the informal caregiver. Tailored information with the use of technology contributed to knowledge in care of older persons and their informal caregivers. HC was shown to contribute to improve care for older people in their home environment.

Trends in Restricting Symptoms at the End of Life from 1998 to 2019: A Cohort Study of Older Persons

OBJECTIVES

To describe changes in the occurrence of restricting symptoms at the end of life from 1998 to 2019 and compare these changes according to the condition leading to death.

DESIGN

Prospective longitudinal study.

SETTING

Greater New Haven, CT.

PARTICIPANTS

A total of 665 decedents from a cohort of 754 community-living persons, 70 years or older.

MEASUREMENTS

The occurrence of 16 restricting symptoms was ascertained during monthly interviews. Information on the conditions leading to death was obtained from death certificates and comprehensive assessments that were completed every 18-months. For each restricting symptom, adjusted rates (per 100 person-months) were calculated separately for six multiyear time intervals.

RESULTS

From 1998 to 2019, rates decreased for five (31.3%) restricting symptoms (difficulty sleeping; chest pain or tightness; shortness of breath; cold or flu symptoms; and nausea, vomiting, or diarrhea), increased for three (18.8%: arm or leg weakness; urinary incontinence; and memory or thinking problem), and changed little for the other eight (50.0%: poor eyesight; anxiety; depression; musculoskeletal pain; fatigue; dizziness or unsteadiness; frequent or painful urination; and swelling in feet or ankles). The decrease in rates was most pronounced for shortness of breath, with a reduction from 15.0 (95% credible interval = 11.7-18.6) in 1998 to 2001 to 8.2 (95% credible interval = 5.9-10.5) in 2014 to 2019, yielding a rate ratio (95% credible interval) of 0.92 (0.86-0.98). When evaluated according to the condition leading to death, the results were similar, with 10 of the 13 statistically significant rate ratios representing decreases in rates over time and only 3 representing increases.

CONCLUSION

The occurrence of most restricting symptoms at the end of life has been decreasing or stable over the past two decades. These results suggest that end-of-life care has been improving, although additional efforts will be needed to further reduce symptom burden at the end of life.

Sustainability of a rural volunteer program (Nav-CARE): a case study

INTRODUCTION

Nav-CARE (Navigation: Connecting, Accessing, Resourcing and Engaging) is an evidence-based program that was implemented over 1 year in a rural community in western Canada. Nav-CARE uses volunteers who are trained in navigation to facilitate access to resources and provide social support to older persons living in the community with serious illness such as cancer, congestive heart failure and chronic obstructive pulmonary disease. Following implementation in which Nav-CARE was found to be feasible, acceptable and have positive outcomes, Nav-CARE was integrated into the local community-based hospice society program. Two years after a successful implementation, it continued to be sustainable in this same rural community. The purpose of this study was to explore the key factors that facilitated the sustainability of Nav-CARE in a rural hospice society.

METHODS

A qualitative single case study design was used with data from several sources collected at different times: (a) pre-implementation, (b) Nav-CARE program implementation (1-year time period), (c) immediately after implementation and (d) 6 months to 2 years after implementation). Data included individual interviews with community stakeholders (n=9), the study volunteer coordinator (n=1), hospice society coordinator (n=1) and Nav-CARE volunteers (n=9). It also included meeting notes of volunteer debriefing sessions and meetings with stakeholders planning for sustainability of Nav-CARE that were held during the 1-year implementation. Data were organized using the i-PARIHS (integrated Promoting Action on Research Implementation in Health Services) framework (a well known implementation framework). Data were analyzed using Yin's qualitative case study approach.

RESULTS

The findings from this case study suggested that key factors in facilitating sustainability of a rural community intervention (Nav-CARE) were the organizational context (inner context) and facilitation (facilitator and facilitation processes). Additionally, the inner context included the fit of Nav-CARE with the organization's priorities, the absorptive capacity of the organization, and organizational structure and mechanisms to integrate Nav-CARE into current programs. The hospice society was well established and supported by the rural community. The role of the facilitator and the planned facilitation processes (training of volunteer navigators, ongoing support and planning events) were key factors in the sustainability of the Nav-CARE program. The findings found that the formal role of the facilitator in the implementation and sustainability of Nav-CARE in this rural community required skills and knowledge, as well as ongoing mentorship. As well, the facilitation process for Nav-CARE included formal sustainability planning meetings involving stakeholders.

CONCLUSION

Using the i-PARIHS framework and a case study approach, key factors for facilitating sustainability were identified. The role of the facilitator, the facilitation processes and the characteristics of the organizational context were important for the sustainability of Nav-CARE. Future research is needed to understand how to assess and enhance an organization's sustainability capacity and the impact of additional facilitator training and mentoring. This study provides a foundation for future research and adds to the discussion of the issue of sustainability of evidence-based interventions in rural community settings.

Effect of a Multifactorial Fall Injury Prevention Intervention on Patient Well-Being: The STRIDE Study

BACKGROUND/OBJECTIVES

In the Strategies to Reduce Injuries and Develop Confidence in Elders (STRIDE) study, a multifactorial intervention was associated with a nonsignificant 8% reduction in time to first serious fall injury but a significant 10% reduction in time to first self-reported fall injury relative to enhanced usual care. The effect of the intervention on other outcomes important to patients has not yet been reported. We aimed to evaluate the effect of the intervention on patient well-being including concern about falling, anxiety, depression, physical function, and disability.

DESIGN

Pragmatic cluster-randomized trial of 5,451 community-living persons at high risk for serious fall injuries.

SETTING

A total of 86 primary care practices within 10 U.S. healthcare systems.

PARTICIPANTS

A random subsample of 743 persons aged 75 and older.

MEASUREMENTS

The well-being measures, assessed at baseline, 12 months, and 24 months, included a modified version of the Fall Efficacy Scale, Patient-Reported Outcomes Measurement Information System (PROMIS) anxiety and depression scales, and Late-Life Function and Disability Instrument.

RESULTS

Participants in the intervention (n = 384) and control groups (n = 359) were comparable in age: mean (standard deviation) of 81.9 (4.7) versus 81.8 (5.0) years. Mean scores were similar between groups at 12 and 24 months for concern about falling, physical function, and disability, whereas the intervention group's mean scores on anxiety and depression were .7 points lower (i.e., better) at 12 months and .6 to .8 points lower at 24 months. For each of these outcomes, differences between the groups' adjusted least square mean changes from baseline to 12 and 24 months, respectively, were quantitatively small. The overall difference in means between groups over 2 years was statistically significant only for depression, favoring the intervention: -1.19 (99% confidence interval, -2.36 to -.02), with 3.5 points representing a minimally important difference.

CONCLUSIONS

STRIDE's multifactorial intervention to reduce fall injuries was not associated with clinically meaningful improvements in patient well-being.

The Contagion of Pneumonia in Older Persons: An Application of the Bass Diffusion Model

This aims to provide an understanding of the spread of pneumonia through analysis of the interaction between infected and potentially infected. Data from 2010 to 2018 on Pneumonia morbidity among older persons age 65 and above was extracted from the Department of Health Field Health Service Information System (FHSIS) annual reports. The data were used to represent the cumulative adopters by fitting them to the Bass diffusion model using the Bass Forecasting Spreadsheet. The number of new adopters was graphed to forecast the diffusion of Pneumonia. The number of cases is expected to increase. The adoption rate in 2024 will be around 45% of the current population. Morbidity of pneumonia is expected to peak in the year 2200, 190 years after the first data. The use of the model provided an insight into the cumulative nature of pneumonia infection due to the interaction between infected and the potentially infected.

Ordinary care in extraordinary times

The Coronavirus Disease 2019 (COVID-19) has accounted for more than 25 000 cases in Ireland with approximately 28% of the clusters in nursing homes as of June 2020. The older population is the most vulnerable to serious complications from this illness and over 90% of deaths due to COVID-19 to date have been in patients over the age of 65. Continuing to provide routine care within nursing homes in these challenging times is an essential part of ensuring that presentations to hospitals for non-essential reasons are minimized. In this article, we describe a project being undertaken by a rural Psychiatry of Old Age Service in the northwest of Ireland. We aim to provide ordinary care in extraordinary times by using mobile tablets within the nursing homes and long-stay facilities in our region for remote video consultations during the COVID-19 crisis.

Factors associated with improvement in depressive symptoms among older persons after hospitalisation - a prospective design with two follow-ups

BACKGROUND

Depression is a common disorder in old age and increases with hospitalisation. The aim was to investigate whether improvement in depressive symptoms after hospitalisation is associated with education level, age, gender, living situation, self-efficacy, activities in daily living and quality of life by (1) examining the prevalence of depressive symptoms at baseline and at 1st and 2nd follow-up (2) examining different factors' association with depressive symptoms at baseline and (3) examining different factors' association with improvement in depressive symptoms at baseline and at 1st and 2nd follow-up.

METHODS

The study consisted of 145 patients, 65 years and older. Data were collected between February 2015 and September 2016 through interviews conducted using structured protocols. The instrument used was Katz index of ADL, Geriatric Depression Scale-20, Life Satisfaction Questionnaire and the General Self-Efficacy Scale. The participants were interviewed before discharge from hospital, after 1.5 month and after 3 months.

RESULTS

The prevalence of depressive symptoms in older persons was high after hospitalisation. Factors associated with improvement of depressive symptoms after hospitalisation were higher educational level, improvement in activities in daily living and quality of life. Non-significant results were found for improvement of depressive symptoms and gender, age, living situation or self-efficacy.

CONCLUSIONS

Depression is a common health problem in older persons, especially after hospitalisation. It is therefore important that healthcare staff screen older persons for depression during hospitalisation, as this allows identification of those in need and a possibility to help them in an appropriate manner. Persons with lower educational level and depressive symptoms need special attention.

Telehealth in Psychiatry of Old Age: Ordinary Care in Extraordinary Times in Rural North-West Ireland

The COVID-19 pandemic has required a rapid evolution of services to maintain routine care in Ireland. Services which had been previously slow to adapt technology in their practices are suddenly integrating various telehealth measures to continue routine practice where possible. In this article, we discuss the challenges we face in rapidly implementing telehealth in a rural Psychiatry of Old Age service in the North-West of Ireland.

Anxiety of Older Persons Living Alone in the Community

Anxiety is a common mental health problem among older persons, and the prevalence is higher in those who live alone than those who live with others. This study aimed to explore the experiences of anxiety in older persons living alone. A descriptive phenomenological approach was used to collect and analyze the interview data from 15 older persons (5 males, 10 females) living alone in Seoul, South Korea. Four main themes emerged from the data analysis: fear of being alone, concern about having an aged body, apprehension mixed with depression and loneliness, and fear of economic difficulties. These findings indicate that older persons living alone should receive continuous attention to prevent them from being neglected and their anxiety from worsening. Above all, it is vital to ensure comprehensive support for older persons living alone to alleviate their anxiety.

Recommendations for a national Coronavirus disease 2019 response guideline for the care of older persons in Nigeria during and post-pandemic: A family physician's perspective

The older persons in our society are a special group of people in need of additional measures of care and protection. They have medical, financial, emotional and social needs. The novel Coronavirus disease 2019 (COVID-19) only exacerbates those needs. COVID-19 is a new disease, and there is limited information regarding the disease. Based on currently available information, older persons and people of any age who have serious underlying medical conditions may be at higher risk of severe illness from COVID-19. Family physicians provide care for individuals across their lifespan. Because geriatricians are internists or family physicians with post-residency training in geriatric medicine, they are major stakeholders in geriatric care. The authors are concerned about the absence of a COVID-19 response guideline/special advisory targeting the vulnerable population of older adults. The management and response to COVID-19 will be implemented in part based on the local context of available resources. Nigeria has been described as a resource-constrained nation. Infection prevention in older persons in Nigeria will far outweigh the possibilities of treatment given limited resources. The aim was to recommend actionable strategies to prevent COVID-19-related morbidity or mortality among older persons in Nigeria and to promote their overall well-being during and after the pandemic. These recommendations cut across the geriatric medicine domains of physical health, mental health, functioning ability and socio-environmental situation.

Learning Integrated Health System to Mobilize Context-Adapted Knowledge With a Wiki Platform to Improve the Transitions of Frail Seniors From Hospitals and Emergency Departments to the Community (LEARNING WISDOM): Protocol for a Mixed-Methods Implementation Study

BACKGROUND

Elderly patients discharged from hospital experience fragmented care, repeated and lengthy emergency department (ED) visits, relapse into their earlier condition, and rapid cognitive and functional decline. The Acute Care for Elders (ACE) program at Mount Sinai Hospital in Toronto, Canada uses innovative strategies, such as transition coaches, to improve the care transition experiences of frail elderly patients. The ACE program reduced the lengths of hospital stay and readmission for elderly patients, increased patient satisfaction, and saved the health care system over Can $4.2 million (US $2.6 million) in 2014. In 2016, a context-adapted ACE program was implemented at one hospital in the Centre intégré de santé et de services sociaux de Chaudière-Appalaches (CISSS-CA) with a focus on improving transitions between hospitals and the community. The quality improvement project used an intervention strategy based on iterative user-centered design prototyping and a "Wiki-suite" (free web-based database containing evidence-based knowledge tools) to engage multiple stakeholders.

OBJECTIVE

The objectives of this study are to (1) implement a context-adapted CISSS-CA ACE program in four hospitals in the CISSS-CA and measure its impact on patient-, caregiver-, clinical-, and hospital-level outcomes; (2) identify underlying mechanisms by which our context-adapted CISSS-CA ACE program improves care transitions for the elderly; and (3) identify underlying mechanisms by which the Wiki-suite contributes to context-adaptation and local uptake of knowledge tools.

METHODS

Objective 1 will involve staggered implementation of the context-adapted CISSS-CA ACE program across the four CISSS-CA sites and interrupted time series to measure the impact on hospital-, patient-, and caregiver-level outcomes. Objectives 2 and 3 will involve a parallel mixed-methods process evaluation study to understand the mechanisms by which our context-adapted CISSS-CA ACE program improves care transitions for the elderly and by which our Wiki-suite contributes to adaptation, implementation, and scaling up of geriatric knowledge tools.

RESULTS

Data collection started in January 2019. As of January 2020, we enrolled 1635 patients and 529 caregivers from the four participating hospitals. Data collection is projected to be completed in January 2022. Data analysis has not yet begun. Results are expected to be published in 2022. Expected results will be presented to different key internal stakeholders to better support the effort and resources deployed in the transition of seniors. Through key interventions focused on seniors, we are expecting to increase patient satisfaction and quality of care and reduce readmission and ED revisit.

CONCLUSIONS

This study will provide evidence on effective knowledge translation strategies to adapt best practices to the local context in the transition of care for elderly people. The knowledge generated through this project will support future scale-up of the ACE program and our wiki methodology in other settings in Canada.

Oral Health Among Older Adults With Complex Needs Living in the Community and in Aged Residential Care Facilities within New Zealand

OBJECTIVES

To describe the oral health status and dental service use of older adults with complex needs living within the community and aged residential care (ARC) facility settings, and to determine associations between dental service utilization and sociodemographic variables.

DESIGN

Secondary analysis of 2 continuously recruited national cohorts.

SETTING AND PARTICIPANTS

Adults aged ≥65 years having standardized assessments between July 1, 2012, and May 31, 2018, within New Zealand and who provided consent.

METHODS

All community-living older people with complex needs undergo a standardized assessment, using the Home Care International Residential Assessment Instrument (interRAI-HC), whereas all ARC facility residents undergo Long Term Care Facilities assessments (interRAI-LTCF). Anonymized data from consenting participants were extracted. Cross-sectional analyses of oral health status and dental service use variables employed logistic regression models, whereas longitudinal analysis of factors influencing dental service utilization employed binary generalized estimating equation models.

RESULTS

Overall, 144,380 interRAI-HC assessments from 97,229 participants, and 195,549 interRAI-LTCF assessments from 62,798 participants were eligible. At first assessment, their average age was 81.9 years (range: 65-109 years) and 84.4 years (range: 65-110 years), respectively. Approximately 65% of the participants wore dentures; 9% had broken, fragmented, loose, or otherwise nonintact natural teeth; and 10% reported difficulties chewing. Overall, only 25.3% of community-dwelling older adults and 17.5% of ARC residents had a dental examination within the previous year. Stark inequalities were observed with, for example, Māori participants having adjusted odds 3.14 [95% confidence interval (CI): 2.88, 3.42] and 2.08 (95% CI: 1.81, 2.39) of not having a dental examination in community and ARC facility settings compared with their New Zealand European counterparts.

CONCLUSIONS AND IMPLICATIONS

Heavy and unequal oral health burdens were observed among older adults with complex needs, together with low dental service uptake. New Zealand needs an oral health policy for older adults.

Vitamin D Synthesis Following a Single Bout of Sun Exposure in Older and Younger Men and Women

Older adults are frequently cited as an at-risk population for vitamin D deficiency that may in part be due to decreased cutaneous synthesis, a potentially important source of cholecalciferol (vitamin D₃). Previous studies found that cutaneous D₃ production declines with age; however, most studies have been conducted ex vivo or in the photobiology lab. The purpose of this study was to characterize the response of vitamin D metabolites following a 30-min bout of sun exposure (15-min each to the dorsal and ventral sides) at close to solar noon in younger and older adults.

METHODS

30 healthy individuals with skin type II/III were recruited; a younger cohort, aged 20-37 (n = 18) and an older cohort (n = 12), age 51-69 years. Exposure was at outer limits of sensible sun exposure designed to enhance vitamin D synthesis without increasing risk of photo ageing and non-melanoma skin cancer. Serum D₃ concentration was measured at baseline, 24, 48 and 72 h post-exposure. Serum 25(OH)D was measured at baseline and 72 h post-exposure plus 168 h post-exposure in the older cohort.

RESULTS

D₃ increased in response to sun exposure (time effect; p = 0.002) with a trend for a difference in D₃ between cohorts (time*group; p = 0.09). By regression modeling of continuous data, age accounted for 20% of the variation in D₃ production. D₃ production decreased by 13% per decade. Despite changes in D₃, however, serum 25(OH)D did not change from baseline to 72 or 168 h post exposure (p > 0.10).

CONCLUSIONS

Serum D₃ concentration increased significantly in response to outdoor sun exposure in younger and older adults. While ageing may dampen cutaneous synthesis, sunlight exposure is still a significant source of vitamin D₃.

Examining the Gaps and Issues of End-of-Life Care among Older Population through the Lens of Socioecological Model-A Multi-Method Qualitative Study of Hong Kong

End-of-life (EOL) care for terminal illness and life-limiting conditions is a sector in the health service spectrum that is drawing increased attention. Despite having the world's longest life expectancy and an ever-escalating demand for long-term care, Hong Kong's EOL care was underdeveloped. The current study aims to provide a holistic picture of gaps and issues to EOL care in Hong Kong. Data collection was conducted using a multi-method qualitative approach that included focus groups and in-depth interviews with key informants and stakeholders, and longitudinal case studies with patients and families. Deductive thematic analysis was used to examine service gaps in current EOL care through the lens of a socioecological model where gaps and issues in various nested, hierarchical levels of care as well as the relationships between these levels were studied in detail. Using the model, we identified gaps and issues of EOL care among older populations in Hong Kong at the policy, legal, community, institutional, as well as intrapersonal and interpersonal levels. These include but are not limited to a lack of overarching EOL care policy framework, ambiguity in the legal basis for mental incapacity, legislative barriers for advance directives, inadequate capacity, resources, and support in the community to administer EOL care, inadequate knowledge, training, and resources for EOL care in health and social care sectors, inadequate medical-social interface, general reluctance and fear of death and dying, as well as the cultural interpretation of filial piety that may lengthen the suffering of the dying patients. Findings highlight the multi-level gaps and issues of EOL care in a place where western and eastern culture meet, and shed light on how best to design more effective and comprehensive policy interventions that will likely have a more sustainable and instrumental impact on facilitating person-centered EOL care during the end of life.

Cost-utility and cost-effectiveness analysis of a clinical medication review focused on personal goals in older persons with polypharmacy compared to usual care: Economic evaluation of the DREAMeR study

AIMS

The ageing society may lead to increasing healthcare expenditure. A clinical medication review (CMR) could potentially reduce costs. The aim of this study is to perform a cost-utility and cost-effectiveness analysis from a societal perspective of a patient-centred CMR.

METHODS

A trial-based cost-utility and cost-effectiveness analysis was performed as part of the DREAMeR study, a pragmatic controlled trial that randomised patients aged ≥70 years using at least seven drugs to either CMR or usual care. Over six months, healthcare consumption and drug use were collected to estimate costs, and effects were collected in terms of quality-adjusted life years (QALYs) measured with EQ-5D-5 L and EQ-VAS and as reduced health-related complaints with impact on patients' daily lives.

RESULTS

The total mean costs per patient (n = 588) over six months were €4,189 ± 6,596 for the control group (n = 294) and €4,008 ± 6,678 for the intervention group (n = 294), including estimated intervention costs of €199 ± 67, which resulted in a mean incremental total cost savings of €181 for the intervention group compared to the control group. Compared to the control group, for the intervention group, the mean incremental QALYs over six months were: -0.00217 measured with EQ-5D and 0.003 measured with EQ-VAS. The incremental effect of reduced health-related complaints with impact was -0.34. There was a likelihood of >90% that the intervention was cost-saving.

CONCLUSIONS

The benefits of a patient-centred CMR were inconsistent with no benefits on HR-QoL measured with EQ-5D-5 L and small benefits on HR-QoL measured with EQ-VAS and health-related complaints with impact on patients' daily lives. Additionally, a CMR could potentially be cost saving from a societal perspective.

Impact of Cognitive Frailty on Activities of Daily Living, Cognitive Function, and Conversion to Dementia Among Memory Clinic Patients with Mild Cognitive Impairment

BACKGROUND

Very few studies have investigated the impact of cognitive frailty in clinical settings, especially in memory clinic populations.

OBJECTIVE

To examine the impact of cognitive frailty on activities of daily living (ADL), cognitive function, and conversion to dementia among memory clinic patients with mild cognitive impairment (MCI).

METHODS

The subjects of this retrospective study were 248 MCI patients (mean age, 76.3±5.4 years; females, 60.9%). All subjects completed a comprehensive geriatric assessment at baseline and at least one assessment during 3-year follow-up. Frailty was defined by generating a frailty index (FI), and MCI patients with frailty (FI≥0.25) were considered to represent cognitive frailty. As primary outcomes, the Barthel Index, Mini-Mental State Examination, and incident dementia were evaluated during follow-up. At baseline, patients were assessed for apolipoprotein E (APOE) phenotype. A linear mixed model, as well as a Cox proportional hazards regression model with adjustment for confounding variables, was performed.

RESULTS

Of these patients, 75 (30.2%) were classified as cognitive frail. APOEɛ4 carriers accounted for 26.7% of those with cognitive frailty and 44.5% of those without (p = 0.008). Cognitive frail patients showed a faster ADL decline (estimate, -1.04; standard error, 0.38; p = 0.007) than patients without cognitive frailty. Cognitive frailty was not associated with cognitive decline and incident dementia.

CONCLUSION

Our findings demonstrated cognitive frailty increases the risk of dependence but not cognitive outcomes. Cognitive frailty may have heterogeneous conditions, including APOEɛ4-related pathologies, which may affect the cognitive trajectories of patients with MCI.

Risk Prediction for Adverse Outcomes for Frail Older Persons with Complex Healthcare and Social Care Needs Admitted to a Community Virtual Ward Model

Purpose

Population ageing is challenging healthcare systems with limited resources, necessitating the development of new care models to address the needs of older, frail community-dwellers. Community Virtual Wards (CVW) reduce adverse events in these patients. We examined the effect of an established CVW on pre-defined health trajectories (between “stable”, “deteriorating”, and “unstable” states) and characteristics that increased the likelihood of adverse healthcare outcomes (hospitalization, institutionalization and death).

Patients and Methods

We collected prospective data on frail patients admitted to a CVW in a single centre in Ireland. Relationships between risk scores, health states and adverse outcomes at 30, 60 and 90 days after admission were examined using multinomial regression analysis.

Results

In total, 88 community-dwellers, mean (±SD) age of 82.8 ±6.4 years, were included. Most were severely frail on the Rockwood Clinical Frailty Scale (mean 6.8/9 ±1.33). Reaching stability (“stable” state) within 30 days was a predictor for stability at 60 and 90 days and remaining at home. Stability was also associated with fewer care episodes (<2) (p=<0.001), a requirement for fewer healthcare professionals (HCP) (<7) (p<0.001) and lower risk of delirium (p<0.001). By contrast, being “unstable” at 60 days increased the numbers of HCP referrals (>7) and was predictive of more acute episodes (>2) and institutionalization or death (p<0.001). Predictors of adverse outcomes of either institutionalization or death included frailty status, function, mobility, nutrition, pressure ulcer risk and cognition.

Conclusion

A CVW model can provide a framework for monitoring and case management to support older people to remain at home or identify those at risk of institutional care. The use of defined health states helped to stratify those at lower or higher risk in an already high-risk frail population. Level of frailty, function, mobility, nutrition, pressure ulcer risks and cognition were predictive of remaining at home and reaching a level of stability or instability/deterioration and institutional care.

The development of a brief measure of health personality

The purpose of this research was to develop a brief assessment of health personality, defined as a set of individual dispositions that are directly related to health. In Study 1, an initial pool of items was developed with 615 older adults, 65 years of age and older. The scale was reduced to a 15-item version for use in applied health care settings. Results indicated that the 'Health Personality Assessment scale' has good internal consistency, and the five-factors correlated significantly with self-reported measures of physical health and well-being. In Study 2, the scale was cross-validated with 254 older adults from the Health Literacy and Cognitive Function among Older Adults Study. The scale was refined and a third study consisted of 3,907 older adults. Reliability and validity of the scale were confirmed. Future research should evaluate the usefulness of this scale in applied healthcare settings.

Prevalence and Potential Predictors of Frailty among Community-Dwelling Older Persons in Northern Thailand: A Cross-Sectional Study

This study aimed to determine the prevalence and associated factors of frailty among Thai older persons. A cross-sectional study was conducted with a representative sample of 1806 older persons aged 60 years or older. Frailty was assessed by Fried’s frailty phenotypes, which consists of five criteria, namely, unintended weight loss, exhaustion, slow walking, weak handgrip and decreased physical activity. Older people who met 3 in 5, 1–2 in 5, and none of the criteria were considered frail, pre-frail and non-frail respectively. The prevalence was calculated and multinomial logistic regression was performed. Prevalence rates of frailty, pre-frailty and non-frailty were 13.9% (95% CI 9.9 to 18.8), 50.9% (95% CI 47.5 to 54.1) and 35.1% (95% CI 31.5 to 39.9), respectively. Increasing age, lower education, having no spouse, poorer health perception, increasing number of comorbidities, osteoarthritis and smaller mid-arm circumference increased the risk of frailty (p < 0.001). The prevalence of geriatric frailty syndrome in this study was much higher than that of developed countries but was lower than that of less developed countries. Factors associated with frailty reflect common characteristics of disadvantaged older persons in Thailand.

Recovery from Severe Disability that Develops Progressively Versus Catastrophically: Incidence, Risk Factors, and Intervening Events

BACKGROUND

Few prior studies have evaluated recovery after the onset of severe disability or have distinguished between the two subtypes of severe disability.

OBJECTIVES

To identify the risk factors and intervening illnesses and injuries (i.e., events) that are associated with reduced recovery after episodes of progressive and catastrophic severe disability.

DESIGN

Prospective longitudinal study of 754 nondisabled community-living persons, aged 70 years or older.

SETTING

Greater New Haven, CT, March 1998 to December 2016.

PARTICIPANTS

A total of 431 episodes of severe disability were evaluated from 385 participants: 116 progressive (115 participants) and 315 catastrophic (270 participants).

MEASUREMENTS

Candidate risk factors were assessed every 18 months. Functional status and exposure to intervening events leading to hospitalization, emergency department visit, or restricted activity were assessed each month. Severe disability was defined as the need for personal assistance with three or more of four essential activities of daily living. Recovery was defined as return to independent function (no disability) within 6 months of developing severe disability.

RESULTS

Recovery occurred among 35.3% (95% confidence interval [CI] = 26.0%-48.0%) and 61.6% (95% CI = 53.5%-70.9%) of the 116 progressive and 315 catastrophic severe disability episodes, respectively. In the multivariable analyses, lives alone, frailty, and intervening hospitalization were each independently associated with reduced recovery from progressive disability, with adjusted hazard ratios (95% CIs) of 0.31 (0.15-0.64), 0.23 (0.12-0.45), and 0.27 (0.08-0.95), respectively, whereas low functional self-efficacy, intervening restricted activity, and intervening hospitalization were each independently associated with reduced recovery from catastrophic disability, with adjusted hazard ratios (95% CIs) of 0.56 (0.40-0.81), 0.55 (0.35-0.85), and 0.45 (0.31-0.66), respectively.

CONCLUSIONS

Recovery of independent function is considerably more likely after the onset of catastrophic than progressive severe disability, the risk factors for reduced recovery differ between progressive and catastrophic severe disability, and subsequent exposure to intervening illnesses and injuries considerably diminishes the likelihood of recovery from both subtypes of severe disability.

Patterns of infection following transrectal ultrasound-guided biopsy of the prostate in a regional New South Wales Centre

OBJECTIVE

To determine the rates, severity and patterns of resistance in patients presenting with post-transrectal ultrasound infection in a regional centre in New South Wales, Australia.

DESIGN

A single-centre retrospective review from August 2013 until August 2017.

SETTING

Murrumbidgee Local Health District, New South Wales.

PARTICIPANTS

All patients who underwent transrectal ultrasonography biopsy of the prostate in the public health system.

MAIN OUTCOME MEASURES

Rate of infection and sepsis following biopsy of the prostate requiring readmission to hospital within 30 days from the procedure.

RESULTS

A total of 317 men underwent transrectal ultrasound-guided biopsy of the prostate over the study period. Nineteen (6%) patients presented with clinical signs of post-transrectal ultrasound infection, of which 18 (5.7%) required readmission for intravenous antibiotics. Median time to readmission was 2 days (0-7), and the average length of hospital stay was 5 days (1-15). Three (0.3%) patients required admission to intensive care for inotropic support. Thirteen patients (68%) had positive blood cultures, and all were positive for Escherichia coli. Four of these patients (21%) had extended spectrum beta-lactamase producing isolates resistant to their preoperative antibiotics.

CONCLUSION

Prostate cancer is common in the elderly community with worse outcomes in regional settings. Infective complications from transrectal ultrasound biopsy were 6% in this regional setting with high rates of multi-resistant organisms. Awareness of this is important for rural health practitioners who are likely to be exposed to this patient population.
