Association between COVID-19 vaccination and critical outcomes among older adults with dementia: a comparative cohort study.

Background: As COVID-19 vaccines became available, understanding their potential benefits in vulnerable populations has gained significance. This study explored the advantages of COVID-19 vaccination in individuals with cognitive disorders by analyzing health-related variables and outcomes. Methods: A prospective cohort study analyzed electronic medical records of 25,733 older adults with cognitive disorders and 65,544 older adults without cognitive disorders from March 2020 to February 2022. COVID-19 vaccination status was the primary exposure variable, categorized as fully vaccinated or unvaccinated. The primary outcomes measured were all-cause mortality and hospitalization rates within 14 and 400 days post-vaccination. Data on vaccination status, demographics, comorbidities, testing history, and clinical outcomes were collected from electronic health records. The study was ethically approved by the relevant medical facility's Institutional Review Board (0075-22-MHS). Results: Vaccinated individuals had significantly lower mortality rates in both groups. In the research group, the mortality rate was 52% (n = 1852) for unvaccinated individuals and 7% (n = 1,241) for vaccinated individuals (p < 0.001). Similarly, in the control group, the mortality rate was 13.58% (n = 1,508) for unvaccinated individuals and 1.85% (n = 936) for vaccinated individuals (p < 0.001), despite higher COVID-19 positivity rates. In the research group, 30.26% (n = 1,072) of unvaccinated individuals tested positive for COVID-19, compared to 37.16% (n = 6,492) of vaccinated individuals (p < 0.001). In the control group, 17.31% (n = 1922) of unvaccinated individuals were COVID-19 positive, while 37.25% (n = 18,873) of vaccinated individuals tested positive (p < 0.001). Vaccination also showed potential benefits in mental health support. The usage of antipsychotic drugs was lower in vaccinated individuals (28.43%, n = 4,967) compared to unvaccinated individuals (37.48%, n = 1,328; 95% CI [0.92-1.28], p < 0.001). Moreover, vaccinated individuals had lower antipsychotic drug prescription rates (23.88%, n = 4,171) compared to unvaccinated individuals (27.83%, n = 968; 95% CI [-1.02 to -0.63], p < 0.001). Vaccination appeared to have a positive impact on managing conditions like diabetes, with 38.63% (n = 6,748) of vaccinated individuals having diabetes compared to 41.55% (n = 1,472) of unvaccinated individuals (95% CI [0.24, 0.48], p < 0.001). Discussion: The findings highlight the importance of vaccination in safeguarding vulnerable populations during the pandemic and call for further research to optimize healthcare strategies for individuals with cognitive disorders.

Exploring physician gender bias in the initiation of prescribing cascades for older men and women: a qualitative clinical vignette study protocol.

INTRODUCTION: A prescribing cascade occurs when a drug is prescribed to manage the often unrecognised side effect of another drug; these cascades are of particular concern for older adults who are at heightened risk for drug-related harm. It is unknown whether, and to what extent, gender bias influences physician decision-making in the context of prescribing cascades. The aim of this transnational study is to explore the potential impact of physician implicit gender biases on prescribing decisions that may lead to the initiation of prescribing cascades in older men and women in two countries, namely: Canada and Italy. METHODS AND ANALYSIS: Male and female primary care physicians at each site will be randomised 1:1 to a case vignette that features either a male or female older patient who presents with concerns consistent with the side effect of a medication they are taking. During individual interviews, while masked to the true purpose of the study, participants will read the vignette and use the think-aloud method to describe their ongoing thought processes as they consider the patient's concerns and determine a course of action. Interviews will be recorded, transcribed verbatim and thematic analysis will be conducted to highlight differences in decisions in the interviews/transcripts, using a common analytical framework across the sites. ETHICS AND DISSEMINATION: This study has received ethics approval at each study site. Verbal informed consent will be received from participants prior to data collection and all data will be deidentified and stored on password-protected servers. Results of this study will be disseminated through peer-reviewed journal articles and presented at relevant national and international conferences.

ThinkCascades: A Tool for Identifying Clinically Important Prescribing Cascades Affecting Older People.

BACKGROUND AND OBJECTIVE: Prescribing cascades occur when a drug is prescribed to manage side effects of another drug, typically when a side effect is misinterpreted as a new condition. A consensus list of clinically important prescribing cascades that adversely affect older persons' health (i.e., where risks of the prescribing cascade usually exceed benefits) was developed to help identify, prevent, and manage prescribing cascades. METHODS: Three rounds of a modified Delphi process were conducted with a multidisciplinary panel of 38 clinicians from six countries with expertise in geriatric pharmacotherapy. The clinical importance of 139 prescribing cascades was assessed in Round 1. Cascades highly rated by ≥ 70% of panelists were included in subsequent rounds. Factors influencing ratings in Rounds 1 and 3 were categorized. After three Delphi rounds, highly rated prescribing cascades were reviewed by the study team to determine the final list of clinically important cascades consistent with potentially inappropriate prescribing. RESULTS: After three rounds, 13 prescribing cascades were highly rated by panelists. Following a study team review, the final tool includes nine clinically important prescribing cascades consistent with potentially inappropriate prescribing. Panelists reported that their ratings were influenced by many factors (e.g., how commonly they encountered the medications involved and the cascade itself, the severity of side effects, availability of alternatives). The relative importance of these factors in determining clinical importance varied by panelist. CONCLUSIONS: A nine-item consensus-based list of clinically important prescribing cascades, representing potentially inappropriate prescribing, was developed. Panelists' decisions about what constituted a clinically important prescribing cascade were multi-factorial. This tool not only raises awareness about these cascades but will also help clinicians recognize these and other important prescribing cascades. This list contributes to the prevention and management of polypharmacy and medication-related harm in older people.

The Contribution of Frailty to Participation of Older Adults.

BACKGROUND: Participation, which is involvement in life situations, is an important indicator of human health and well-being of older adults. Frailty is known to be related to difficulties in activities of daily living (ADL) but the association with participation restriction has not been sufficiently researched. Therefore, we aimed to (1) to assess the correlations between frailty, ADL, and participation; and (2) to identify the contribution of frailty to explaining the participation restriction of older adults. METHODS: A cross-sectional study included home visits to community-dwelling older adults aged 75 and older. The Reintegration to Normal Living Index (RNL-I) assessed participation, PRISMA-7 assessed frailty, and the Functional Independence Measure and IADL questionnaire assessed the basic and instrumental ADL. Cognition, which may explain participation, was also assessed (The Montreal Cognitive Assessment) and demographic information was collected. RESULTS: Older adults (N = 121, 60 women), aged 75 to 91 years (mean (SD)-79.6 (3.1)), were included. Older adults demonstrated full to restricted participation (RNL-I-mean (SD)-78.2 (18.0)/100). Frailty was identified in 39 (32%) older adults (mean (SD) PRISMA-7-2.9 (1.4)/7points). A negative moderate significant correlation was found between participation and frailty (r = -0.634, p < 0.001). The variance of participation was significantly explained by frailty, 31.5%, and basic ADL, 5.6% (after controlling for age and cognition); the total model explained 44.6% (F = 23.29, p < 0.001). CONCLUSIONS: Frailty is significantly associated with participation restriction. Since participation has many health benefits, understanding which factors are associated to participation is central to developing interventions for older adults. These findings may help health professionals in the future develop interventions for maintaining and promoting the participation of older adults.

Prevalence and Incidence Rates of Dementia: A Nationwide Population-Based Study of Electronic Health Records in Israel.

BACKGROUND: Data on the rate of dementia is essential for planning and developing appropriate services at the national level. OBJECTIVE: We report the prevalence and incidence of dementia, based on electronic health records available for the whole population. METHODS: This national dementia dataset was established as a part of the National Program to Address Alzheimer's and Other Types of Dementia. Data from medical health records for all persons aged 45+ in Israel, for 2016, were extracted from the databases of the four health maintenance organizations. Dementia cases were identified based on either recorded dementia diagnosis, through International Classification of Diseases (ICD-9 and ICD-10) or dispensation of anti-dementia drugs. The date of first diagnosis was determined by the earliest recording. RESULTS: A total of 65,951 persons with dementia, aged 45+, were identified from electronic health data. Based on both ICD codes and anti-dementia drugs, the prevalence rates of dementia among individuals aged 45+ and 65+ in 2016 were 2.5%and 6.4%, respectively, and the incidence rates were 0.49%and 1.3%, respectively. Based on ICD codes alone, the prevalence rates of dementia among individuals aged 45+ and 65+ in 2016 were 2.1%and 5.4%respectively, and the incidence rates were 0.36%and 0.96%respectively. The rates were higher among females compared to males and paradoxically lower in lower socioeconomic status compared to higher statuses. CONCLUSION: This data collection reflects the present access of dementia patients to medical care resources and provides the basis for service planning and future dementia policies.

Falls and fear of falling among Israeli community-dwelling older people: a cross-sectional national survey.

BACKGROUND: Falls and fear of falling are a major problem for older people and a leading cause of functional decline and institutionalization. There is limited data on the prevalence of falls in a 12-month period among Israeli older adults. Our main objective was to evaluate the prevalence of falls among Israeli community-dwelling older people aged ≥65 years and to identify factors associated with falls and fear of falling. METHODS: A national cross-sectional interview survey was conducted between February 2018 and April 2019 by the Israeli Center for Disease Control. The prevalence of falls was assessed by asking participants about falling within the 12 months prior to the survey. Fear of falling was assessed by asking participants about the fear of future falls. Multivariate analysis was used to identify factors associated with falls and with fear of falling. RESULTS: From 5281 households that were eligible for inclusion in this study, 3242 participants (61.4%) completed the survey. Falling at least once in the past year was reported by 23.8% of the respondents and fear of falling by 48.2%. The majority of the participants (91.1%) reported that they had never received any instruction about fall prevention from their medical care provider. In the multivariate analysis, falls and fear of falling were each a risk factor for the other; and were also significantly associated with female gender, major functional difficulties, the use of walking aids, cardiac disease, diabetes mellitus and psychotropic medications. CONCLUSION: The prevalence of falls and fear of falling among Israeli community-dwelling older people is comparable to the rates published in other countries. Efforts should be made to increase awareness about falls and their health consequences among older people. The development of specific interventions to target those at higher risk for falls and fear of falling is strongly recommended.

Palliative Care in Advanced Dementia: Comparison of Strategies in Three Countries.

Palliative care including hospice care is appropriate for advanced dementia, but policy initiatives and implementation have lagged, while treatment may vary. We compare care for people with advanced dementia in the United States (US), The Netherlands, and Israel. We conducted a narrative literature review and expert physician consultation around a case scenario focusing on three domains in the care of people with advanced dementia: (1) place of residence, (2) access to palliative care, and (3) treatment. We found that most people with advanced dementia live in nursing homes in the US and The Netherlands, and in the community in Israel. Access to specialist palliative and hospice care is improving in the US but is limited in The Netherlands and Israel. The two data sources consistently showed that treatment varies considerably between countries with, for example, artificial nutrition and hydration differing by state in the US, strongly discouraged in The Netherlands, and widely used in Israel. We conclude that care in each country has positive elements: hospice availability in the US, the general palliative approach in The Netherlands, and home care in Israel. National Dementia Plans should include policy regarding palliative care, and public and professional awareness must be increased.

Identifying key prescribing cascades in older people (iKASCADE): a transnational initiative on drug safety through a sex and gender lens-rationale and design.

PURPOSE: To describe the objectives, methods and expected impact of an international consortium (iKASCADE) whose purpose is to improve drug safety for older adults by addressing prescribing cascades through a sex and gender lens. METHODS: To create a comprehensive, internationally relevant inventory of prescribing cascades affecting older adults, the consortium has created a modified Delphi procedure where international experts in prescribing and managing pharmacotherapy for older adults will rank a list of prescribing cascades as to their clinical importance. We will use administrative and clinical data on older adults to evaluate the frequency of prescribing cascades by sex internationally, in the hospital, long-term care and community settings. Finally, we will use semi-structured interviews and realistic, country-specific vignettes, each incorporating a prescribing cascade with identified sex differences, to explore how socially constructed gender roles contribute to the experience, presentation and management of prescribing cascades. RESULTS: The consortium will synthesize the quantitative and qualitative results to produce a position paper and products-aimed at knowledge users within and outside of academia-designed to elevate the importance of integrating a gender dimension in the identification and prevention of prescribing cascades. CONCLUSION: Findings will improve our understanding of how adverse drug events are different between older women and men and inform the development and dissemination of tailored knowledge translation products to reduce the frequency and impact of prescribing cascades.

Polypharmacy, inappropriate prescribing, and deprescribing in older people: through a sex and gender lens.

Polypharmacy is very common in older adults and increases the risk of inappropriate and unsafe prescribing for older adults. Older adults, particularly women (who make up the majority of this age group), are at the greatest risk for drug-related harm. Therefore, optimising drug prescribing for older people is very important. Identifying potentially inappropriate medications and opportunities for judicious deprescribing processes are intrinsically linked, complementary, and essential for optimising medication safety. This Review focuses on optimising prescribing for older adults by reducing doses or stopping drugs that are potentially harmful or that are no longer needed. We explore how sex (biological) and gender (sociocultural) factors are important considerations in safe drug prescribing. We conclude by providing a practical approach to optimising medication safety that clinicians can routinely apply to the care of their older patients, highlighting how sex and gender considerations inform medication decision making.

The Israel Registry for Alzheimer's Prevention (IRAP) Study: Design and Baseline Characteristics.

BACKGROUND: Family history of Alzheimer's disease (AD) is associated with increased dementia-risk. OBJECTIVE: The Israel Registry for Alzheimer's Prevention (IRAP) is a prospective longitudinal study of asymptomatic middle-aged offspring of AD patients (family history positive; FH+) and controls (whose parents have aged without dementia; FH-) aimed to unravel the contribution of midlife factors to future cognitive decline and dementia. Here we present the study design, methods, and baseline characteristics. METHODS: Participants are members of the Maccabi Health Services, 40-65 years of age, with exquisitely detailed laboratory, medical diagnoses and medication data available in the Maccabi electronic medical records since 1998. Data collected through IRAP include genetic, sociodemographic, cognitive, brain imaging, lifestyle, and health-related characteristics at baseline and every three years thereafter. RESULTS: Currently IRAP has 483 participants [mean age 54.95 (SD = 6.68) and 64.8% (n = 313) women], 379 (78.5%) FH+, and 104 (21.5%) FH-. Compared to FH-, FH+ participants were younger (p = 0.011), more often males (p = 0.003) and with a higher prevalence of the APOE E4 allele carriers (32.9% FH+, 22% FH-; p = 0.040). Adjusting for age, sex, and education, FH+ performed worse than FH-in global cognition (p = 0.027) and episodic memory (p = 0.022). CONCLUSION: Lower cognitive scores and higher rates of the APOE E4 allele carriers among the FH+ group suggest that FH ascertainment is good. The combination of long-term historical health-related data available through Maccabi with the multifactorial information collected through IRAP will potentially enable development of dementia-prevention strategies already in midlife, a critical period in terms of risk factor exposure and initiation of AD-neuropathology.

[GERIATRICS AT CENTER STAGE].

INTRODUCTION: Demographic changes in the developed world have resulted in population aging. Although Israel has a relatively young population, the older population is aging at a rapid rate. This has placed significant strains on health services in the community, in acute care, rehabilitation and long-term care. Geriatric medicine stands at the forefront of providing high quality care to the older population. The recognition of the importance of the "Geriatric Giants", which include immobility, instability (falls), incontinence, intellectual impairment (dementia and delirium), and iatrogenesis (including polypharmacy), has resulted in the development of improved diagnosis, prevention and treatment of these syndromes. The knowledge and understanding of aging and age-related diseases, and the development of a multidisciplinary function-based approach to assessment and treatment, have resulted in geriatricians playing a central role in the health care of older people. The current issue of Harefuah presents an overview of topics and studies of interest to Israeli researchers.

Where did I put my glasses? The lived experience of older adults seeking medical help for perceived memory problems.

Purpose: This study aimed to examine the lived experience of older adults who seek medical help for perceived memory problems, defined as "help-seekers." We examined how they make sense of their experience of memory problems, the effect on everyday life and the role of personal and environmental factors.Materials and methods: A qualitative approach was used. Twelve help-seekers recruited from geriatric clinics participated in qualitative interviews, using thematic analysis with an interpretative phenomenological analysis.Results: Four themes emerged: (1) memory problems in daily life; (2) negative beliefs and emotional responses; (3) coping with memory problems; and (4) memory problems in context. The study describes the implications of memory problems on engagement in meaningful and self-defining occupations, and the negative beliefs and emotions embedded in the experience of memory loss. The results revealed three types of coping responses: active problem solving, reframing perception of the problem and avoidant behaviors. The study highlights the importance of both the social environment and aging process in the lived experience of help-seekers.Conclusions: Multiple personal and social factors interacted and mediated the meaning of memory loss in help-seekers. The study reveals a complex clinical picture that may impede successful occupational engagement of help-seekers.Implications for rehabilitationThe evaluation of older adults reporting memory problems should include assessments of everyday functioning, memory related beliefs, emotional status, self-efficacy, and the social environment.The interaction between memory problems and bio-psycho-social changes related to aging should be considered in treating older adults with reported memory problems.Design of group interventions addressing daily functioning, coping strategies and memory related beliefs are recommended.

Home hospice for older people with advanced dementia: a pilot project.

BACKGROUND: Dementia is a terminal illness making the palliative and hospice approach to care appropriate for older people with advanced dementia. OBJECTIVE: To examine clinical and health services outcomes of a quality improvement pilot project to provide home hospice care for older people with advanced dementia. STUDY DESIGN: Twenty older people with advanced dementia being treated in the Maccabi Healthcare Services homecare program, received home hospice care as an extension of their usual care for 6-7 months (or until they died) from a multidisciplinary team who were available 24/7. Family members were interviewed using validated questionnaires about symptom management, satisfaction with care, and caregiver burden. Hospitalizations prevented and medications discontinued, were determined by medical record review and team consensus. FINDINGS: The findings are based on 112 months of care with an average of 5.6 (SD 1.6) months per participant. The participants were on average 83.5 (SD 8.6) years old, 70% women, in homecare for 2.8 (SD 2.0) years, had dementia for 5.6 (SD 3.6) years with multiple comorbidities, and had been hospitalized for an average of 14.0 (SD 18.1) days in the year prior to the project. Four patients were fed via artificial nutrition. During the pilot project, 4 patients died, 2 patients withdrew, 1 patient was transferred to a nursing home and 13 returned to their usual homecare program. The home hospice program lead to significant (p < 0.001)improvement in: symptom management (score of 33.8 on admission on the Volicer symptom management scale increased to 38.3 on discharge), in satisfaction with care (27.5 to 35.3,), and a significant decline in caregiver burden (12.1 to 1.4 on the Zarit Burden index). There were five hospitalizations, and 33 hospitalizations prevented, and an average of 2.1(SD 1.4) medications discontinued per participant. Family members reported that the professionalism and 24/7 availability of the staff provided the added value of the program. CONCLUSIONS: This pilot quality improvement project suggests that home hospice care for older people with advanced dementia can improve symptom management and caregiver satisfaction, while decreasing caregiver burden, preventing hospitalizations and discontinuing unnecessary medications. Identifying older people with advanced dementia with a 6 month prognosis remains a major challenge.

Dementia care in Israel: top down and bottom up processes.

Dementia is one of the main causes of disability among older adults and is viewed as one of the most distressing and devastating of conditions. Dementia has a profound impact on those who suffer from the disease and on their family caregivers. In this article, we describe the added benefit of implementing top-down and bottom-up strategies in the process of influencing and developing healthcare services. We use Israel as an example to argue that breakthroughs in care implementation and development of services are more likely to occur when there is a convergence of top-down and bottom-up processes. In the first section of the article, we present the top-down plans, initiated to address the needs of people with dementia and their families. In the second section, we present examples of bottom-up projects that developed in Israel before and after the top-down plans were initiated. In the third section, we contend that it is the combination of these top-down and bottom-up strategies that led to a breakthrough and the expansion of services for people with dementia and their families, and we argue that the Israeli case study is applicable to other health systems.

Beyond memory problems: multiple obstacles to health and quality of life in older people seeking help for subjective memory complaints.

BACKGROUND: Preliminary evidence suggests that older people who seek medical help for subjective memory complaints (SMC) may be at risk for depression, poor quality of life (QoL), and functional limitations. This study aims to: (1) further investigate bio-psycho-social characteristics, participation in personally meaningful activities and QoL of help-seekers; and (2) examine the relationship of these characteristics to QoL, and explore the unique contribution of participation to QoL. METHODS: Cognitive, meta-cognitive, emotional, social, participation, and QoL measures were used to compare 51 help-seekers referred from geriatric clinics to 40 age-matched controls who did not seek help for memory problems. RESULTS: Help-seekers exhibited lower participation and QoL, had lower mean cognitive scores, reported more memory mistakes and negative memory-beliefs, more depression, worse self-efficacy, and less positive social interaction than non-help-seekers. Quality of life in help-seekers was significantly correlated with most variables. Participation contributed to the explained variance of QoL in help-seekers, beyond that accounted for by cognition and emotional status. DISCUSSION: Help-seekers with SMC exhibited a complex health condition that includes not only SMC, but also objective memory impairment, depression, functional restrictions, negative memory beliefs, low perception of memory abilities, reduced self-efficacy and insufficient social interactions, all associated with lower QoL. This multi-faceted condition should be considered in the treatment of help-seekers. Implications for Rehabilitation Older people who seek help for subjective memory complaints may be facing a larger problem involving bio-psycho-social factors, affecting participation in meaningful activities and quality of life. Quality of life may be improved via treatment of depression, functional restrictions, memory beliefs, self-efficacy, and positive social interactions. Participation in meaningful activities is an especially important target for improving health and quality of life in this population. Interventions for older adults seeking help for subjective memory complaints will benefit from adopting a bio-psycho-social rehabilitation perspective.
