Detecting Cognitive Impairment and Dementia in the Emergency Department: A Scoping Review

ObjectivesTo identify research and practice gaps to establish future research priorities to advance the detection of cognitive impairment and dementia in the emergency department (ED).DesignLiterature review and consensus-based rankings by a transdisciplinary, stakeholder task force of experts, persons living with dementia, and care partners.Setting and ParticipantsScoping reviews focused on adult ED patients.MethodsTwo systematic scoping reviews of 7 medical research databases focusing on best tools and approaches for detecting cognitive impairment and dementia in the ED in terms of (1) most accurate and (2) most pragmatic to implement. The results were screened, reviewed, and abstracted for relevant information and presented at the stakeholder consensus conference for discussion and ranked prioritization.ResultsWe identified a total of 1464 publications and included 45 to review for accurate tools and approaches for detecting cognitive impairment and dementia. Twenty-seven different assessments and instruments have been studied in the ED setting to evaluate cognitive impairment and dementia, with many focusing on sensitivity and specificity of instruments to screen for cognitive impairment. For pragmatic tools, we identified a total of 2166 publications and included 66 in the review. Most extensively studied tools included the Ottawa 3DY and Six-Item Screener (SIS). The SIS was the shortest to administer (1 minute). Instruments with the highest negative predictive value were the SIS (vs MMSE) and the 4 A's Test (vs expert diagnosis). The GEAR 2.0 Advancing Dementia Care Consensus conference ranked research priorities that included the need for more approaches to recognize more effectively and efficiently persons who may be at risk for cognitive impairment and dementia, while balancing the importance of equitable screening, purpose, and consequences of differentiating various forms of cognitive impairment.Conclusions and ImplicationsThe scoping review and consensus process identified gaps in clinical care that should be prioritized for research efforts to detect cognitive impairment and dementia in the ED setting. These gaps will be addressed as future GEAR 2.0 research funding priorities.     

Emergency Department Communication in Persons Living With Dementia and Care Partners: A Scoping Review

ObjectivesTo synthesize published research exploring emergency department (ED) communication strategies and decision-making with persons living with dementia (PLWD) and their care partners as the basis for a multistakeholder consensus conference to prioritize future research.DesignSystematic scoping review.Settings and ParticipantsPLWD and their care partners in the ED setting.MethodsInformed by 2 Patient-Intervention-Comparison-Outcome (PICO) questions, we conducted systematic electronic searches of medical research databases for relevant publications following standardized methodological guidelines. The results were presented to interdisciplinary stakeholders, including dementia researchers, clinicians, PLWD, care partners, and advocacy organizations. The PICO questions included: How does communication differ for PLWD compared with persons without dementia? Are there specific communication strategies that improve the outcomes of ED care? Future research areas were prioritized.ResultsFrom 5451 studies identified for PICO-1, 21 were abstracted. From 2687 studies identified for PICO-2, 3 were abstracted. None of the included studies directly evaluated communication differences between PLWD and other populations, nor the effectiveness of specific communication strategies. General themes emerging from the scoping review included perceptions by PLWD/care partners of rushed ED communication, often exacerbated by inconsistent messages between providers. Care partners consistently reported limited engagement in medical decision-making. In order, the research priorities identified included: (1) Barriers/facilitators of effective communication; (2) valid outcome measures of effective communication; (3) best practices for care partner engagement; (4) defining how individual-, provider-, and system-level factors influence communication; and (5) understanding how each member of ED team can ensure high-quality communication.Conclusions and ImplicationsResearch exploring ED communication with PLWD is sparse and does not directly evaluate specific communication strategies. Defining barriers and facilitators of effective communication was the highest-ranked research priority, followed by validating outcome measures associated with improved information exchange.     

Optimal Emergency Department Care Practices for Persons Living With Dementia: A Scoping Review

ObjectivesTo summarize research on optimal emergency department (ED) care practices for persons living with dementia (PLWDs) and develop research priorities.DesignSystematic scoping review.Settings and ParticipantsPLWDs in the ED.MethodsThe following Patient-Intervention-Comparison-Outcome (PICO) questions were developed: PICO 1, What components of emergency department care improve patient-centered outcomes for persons with dementia? PICO 2, How do emergency care needs for persons with dementia differ from other patients in the emergency department? A scoping review was conducted following PRISMA-ScR guidelines and presented to the Geriatric Emergency care Applied Research 2.0 Advancing Dementia Care network to inform research priorities.ResultsFrom the 6348 publications identified, 23 were abstracted for PICO 1 and 26 were abstracted for PICO 2. Emergency care considerations for PLWDs included functional dependence, behavioral and psychological symptoms of dementia, and identification of and management of pain. Concerns regarding ED care processes, the ED environment, and meeting a PWLD's basic needs were described. A comprehensive geriatric assessment and dedicated ED unit, a home hospital program, and a low-stimulation bed shade and contact-free monitor all showed improvement in patient-centered or health care use outcomes. However, all were single-site studies evaluating different outcomes. These results informed the following research priorities: (1) training and dementia care competencies; (2) patient-centric and care partner–centric evaluation interventions; (3) the impact of community- and identity-based factors on ED care for PLWDs; (4) economic or other implementation science measures to address viability; and (5) environmental, operational, personnel, system, or policy changes to improve ED care for PLWDs.Conclusions and ImplicationsA wide range of components of both ED care practices and ED care needs for PLWDs have been studied. Although many interventions show positive results, the lack of depth and reproducible results prevent specific recommendations on best practices in ED care for PLWDs.     

A survey of emergency department staff about challenges and recommendations for emergency department care of extended care facility patients

ObjectivesExtended care facility (ECF) patients who transfer to emergency departments (EDs) can pose problems when complicated health problems require extra resources. Higher numbers of older patients are projected to use EDs, so we aimed to identify problems now to implement solutions before they worsen in the future.DesignThis was a prospective survey research study.SettingED in a safety net teaching hospital in the Midwest.ParticipantsED personnel.MeasurementsConfidential, anonymous survey collected views and opinions of ED personnel about problematic issues related to emergency care of ECF residents. The survey targeted communication problems, patient satisfaction concerns, difficult characteristics of patient population, need for education, need for research—and solicited open-ended remarks.ResultsED staff reported concern about flawed communication and poor documentation from the ECF. Based on job title, divergent viewpoints were reported about pharmacological challenges and comfort levels in managing older patients in the ED. Top training priorities were special needs of older adults, detecting abuse in older adults, and specific medical and psychosocial issues associated with older adults. Increased communication among all levels of geriatric care is recommended, especially from extended care facility staff before patient arrival at the ED.ConclusionBecause population projections predict an increasing trend of older adults, health care providers must think ahead and prepare for future medical needs. This survey was an inexpensive and effective way to identify next steps. We plan to use the survey results to initiate collaboration with ED staff, EMS providers, and ECF staff to identify specific actions to improve acute care for elderly patients—for the present and the future.     

Telemedicine and Dementia Care: A Systematic Review of Barriers and Facilitators

ObjectivesAn increasing reliance on telemedicine for older adults with cognitive impairment requires a better understanding of the barriers and facilitators for this unique patient population.DesignThe study team queried PubMed, Embase, the Cochrane Library, PsycINFO, CINAHL, Scopus, and ClinicalTrials.gov on May 1, 2020, for studies in English published from January 2010 to May 2020.Setting and ParticipantsWe conducted a systematic review of articles investigating the use of telemedicine among older adults with Alzheimer's disease and related dementia (ADRD) or mild cognitive impairment (MCI) that focused on the patient and care partner perspectives.MethodsTelemedicine encounter purpose, technological requirements, and findings regarding sensory needs were extracted. The Cochrane Collaboration's Risk of Bias Tool was applied for quality assessment.ResultsThe search yielded 3551 abstracts, from which 90 articles were reviewed and 17 were included. The purpose of telemedicine encounters included routine care, cognitive assessment, and telerehabilitation. All studies reported successful implementation of telemedicine, supported by patient and care partner satisfaction, similar results on cognitive assessment and diagnosis compared to in-person visits, and improvement in outcome measures following rehabilitation. Sixteen studies relied on staff and care partners to navigate technologies. Six studies reported participants reporting difficulty hearing the provider during the telemedicine visits. Five studies excluded participants with visual or hearing impairment because of the potential difficulty of using telemedicine technology. No studies reported technological adaptations to account for sensory impairment.Conclusions and ImplicationsTelemedicine is well received among patients and care partners, but successful delivery incorporates support staff and the care partners to navigate technologies. The exclusion of older adults with sensory impairment, especially given that it is highly prevalent, in developing telemedicine systems may further exacerbate access to care in this population. Adapting technologies for sensory needs is critical to the advancement of accessible dementia care through telemedicine.     

Fully Immersive Virtual Reality Using 360° Videos to Manage Well-Being in Older Adults: A Scoping Review

ObjectiveThe development of negative behavioral and psychosocial factors (depression, anxiety, apathy, etc) is associated with poor well-being, which can contribute to health issues in ageing, especially in the context of COVID-19. Despite its relative novelty, fully immersive virtual reality (VR) interventions through 360° immersive videos are becoming more accessible and flexible and constitute an emerging method to potentially enhance well-being. The aim of this scoping review is to assess the effectiveness of 360° interventions on well-being in older adults with or without cognitive impairment, as well as cybersickness and attitudes toward this technology.DesignScoping review.Setting and ParticipantsOlder adults with or without cognitive impairment.MethodsThe PRISMA-SR guideline was followed. Four databases were used, and we selected articles published until April 2022. We have analyzed the effect of 360° videos on the well-being of older adults with respect to the study design, the population, the contents, the duration of intervention, and the outcomes.ResultsA total of 2262 articles were screened, of which 10 articles were finally included in this review. Most of them are pilot studies and used mixed methods including scales and interviews. The material and content of VR are diversified. Many behavioral and psychological outcomes were assessed, including anxiety, apathy, loneliness, depression, social engagement, quality of life, and emotions. The results were positive or mixed, according to the outcomes. We recorded few adverse events, and the interviews show contrasting results concerning the participants’ feelings (ie, degree of immersion, familiarity with technology, and VR content).Conclusions and ImplicationsThe use of VR 360° videos seems feasible in community-dwelling older adults or residential aged care facilities, as they are safe and provide enjoyment. It constitutes an emerging and promising therapeutic tool to manage psychosocial disorders. This review provides key considerations for the design and implementation of interventions using VR 360° video in clinical practice.     

Understanding risk of falls in people with cognitive impairment living in residential care

ObjectivesTo better understand fall risk factors in older adults with cognitive impairment living in residential care.DesignA prospective observational cohort study.SettingResidential care homes in South London, UK.ParticipantsResidents older than 60, with cognitive impairment who had a life expectancy of at least 6 months and were not bedbound or recently discharged from hospital.MeasurementsBaseline assessments were undertaken in domains of demographics, medical history, medication use, behavior, affect, gait, balance, sensorimotor performance and neuropsychological function. Participants were followed for 6 months for falls using care home reporting systems.ResultsA total of 109 participants completed baseline assessment and had adequate falls follow-up. Fallers took more medications, were more likely to be taking antidepressants, had more functional impairment, poorer balance and gait, were more impulsive and anxious, exhibited more dementia-related behaviors, and performed worse on cognitive tests involving attention and orientation, memory, and fluency. Logistic regression analysis identified 4 significant and independent predictors of falls: poor attention and orientation, increased postural sway with eyes closed, anxiety, and antidepressant use. The AUC for this model was 0.84 (95% CI 0.76–0.91).ConclusionsThis study identified important risk factors for falls potentially amenable to intervention in older people with cognitive impairment living in residential care. This information may be useful in designing effective approaches to fall prevention in this high-risk population.     

A scoping review of COVID-19 experiences of people living with dementia

ObjectivesCompared with the general population, people living with dementia have been unequivocally affected by the COVID-19 pandemic. However, there is a paucity of knowledge on the COVID-19 impact on people with dementia and their care partners. The objective of this scoping review was to synthesize the existing literature on the COVID-19 experiences of people with dementia and their care partners.MethodsFollowing Arksey and O’Malley’s scoping review framework, we searched five electronic databases (Scopus, PubMed, CINAHL, EMBASE, and Web of Science) and an online search engine (Google Scholar). Inclusion criteria consisted of English-language articles focusing on the COVID-19 experiences of people with dementia and their care partners.SynthesisTwenty-one articles met our inclusion criteria: six letters to the editor, seven commentaries, and eight original research studies. In the literature, five main themes were identified: (i) care partner fatigue and burnout; (ii) lack of access to services and supports; (iii) worsening neuropsychiatric symptoms and cognitive function; (iv) coping with COVID-19; and (v) the need for more evidence-informed research. Factors such as living alone, having advanced dementia, and the length of confinement were found to exacerbate the impact of COVID-19.ConclusionUrgent action is needed to support people living with dementia and their care partners in the pandemic. With little access to supports and services, people with dementia and their care partners are currently at a point of crisis. Collaboration and more evidence-informed research are critical to reducing mortality and supporting people with dementia during the pandemic.     

Combined Effects of Cognitive Impairment and Nutritional Trajectories on Functional Recovery for Older Patients after Hip-Fracture Surgery

ObjectivesMalnutrition and cognitive impairment are associated with poor functional recovery in older adults following hip-fracture surgery. This study examined the combined effects of cognitive impairment and nutritional trajectories on postoperative functional recovery for older adults following hip-fracture surgery.DesignProspective longitudinal correlational study.Setting and ParticipantsThis study recruited 350 older adults (≥60 years of age) who received hip-fracture surgery at a 3000-bed medical center in northern Taiwan from September 2012 to March 2020.MethodsParticipant data were collected over a 2-year period after surgery for nutritional and cognitive status and activities of daily living (ADLs). Participants were grouped by type of nutritional trajectory using group-based trajectory modeling. Generalized estimating equations analyzed associations between trajectory groups/cognitive status at discharge and performance of ADLs.ResultsNutritional trajectories best fit a 3-group trajectory model: malnourished (19%), at-risk of malnutrition (40%), and well-nourished (41%). Nutritional status for the malnourished group declined from 12 months to 24 months following surgery; nutritional status remained stable for at-risk of malnutrition and well-nourished groups. Interactions for cognitive impairment-by-nutritional status were significant: the malnourished + intact cognition subgroup had significantly better ADLs than the malnourished + cognitive impairment subgroup (b = 27.1, 95% confidence interval = 14.0–40.2; P < .001). For at-risk of malnutrition and well-nourished groups, there were no significant differences between cognitive impairment and intact cognition in ADLs. These findings suggest that nutritional status may buffer the negative effect of cognitive impairment on ADLs.Conclusions and ImplicationsBetter nutritional status over time for older adults following hip fracture can protect against adverse influences of cognitive impairment on ADLs during postoperative recovery. Participants with malnutrition and cognitive impairment had the poorest ADLs. These findings suggest interventions tailored to improving nutritional status may improve recovery for older adults following hip-fracture surgery.     

Effective stakeholder participation in setting research priorities using a Global Evidence Mapping approach

ObjectiveWe present a multistep process for identifying priority research areas in rehabilitation and long-term care of traumatic brain-injured (TBI) patients. In particular, we aimed to (1) identify which stakeholders should be involved; (2) identify what methods are appropriate; (3) examine different criteria for the generation of research priority areas; and (4) test the feasibility of linkage and exchange among researchers, decision makers, and other potential users of the research.Study Design and SettingPotential research questions were identified and developed using an initial scoping meeting and preliminary literature search, followed by a facilitated mapping workshop and an online survey. Identified research questions were then prioritized against specific criteria (clinical importance, novelty, and controversy). Existing evidence was then mapped to the high-priority questions using usual processes for search, screening, and selection. A broad range of stakeholders were then brought together at a forum to identify priority research themes for future research investment. Using clinical and research leaders, smaller targeted planning workshops prioritized specific research projects for each of the identified themes.ResultsTwenty-six specific questions about TBI rehabilitation were generated, 14 of which were high priority. No one method identified all high-priority questions. Methods that relied solely on the views of clinicians and researchers identified fewer high-priority questions compared with methods that used broader stakeholder engagement. Evidence maps of these high-priority questions yielded a number of evidence gaps. Priority questions and evidence maps were then used to inform a research forum, which identified 12 priority themes for future research.ConclusionOur research demonstrates the value of a multistep and multimethod process involving many different types of stakeholders for prioritizing research to improve the rehabilitation outcomes of people who have suffered TBI. Enhancing stakeholder representation can be augmented using a combination of methods and a process of linkage and exchange. This process can inform decisions about prioritization of research areas.     

Taxonomy of Interventions to Reduce Acute Care Transfers From Long-term Care Homes: A Systematic Scoping Review

ObjectiveTo develop a taxonomy of interventions aimed at reducing emergency department (ED) transfers and/or hospitalizations from long-term care (LTC) homes.DesignA systematic scoping review.Setting and participantsPermanent LTC home residents.MethodsExperimental and comparative observational studies were searched in MEDLINE, CINAHL, Embase Classic + Embase, the Cochrane Library, PsycINFO, Social Work Abstracts, AMED, Global Health, Health and Psychosocial Instruments, Joanna Briggs Institute EBP Database, Ovid Healthstar, and Web of Science Core Collection from inception until March 2020. Forward/backward citation tracking and gray literature searches strengthened comprehensiveness. The Mixed Methods Appraisal Tool was used to assess study quality. Intervention categories and components were identified using an inductive-deductive thematic analysis. Categories were informed by 3 intervention dimensions: (1) “when/at what point(s)” on the continuum of care they occur, (2) “for whom” (ie, intervention target resident populations), and (3) “how” these interventions effect change. Components were informed by the logistical elements of the interventions having the potential to influence outcomes. All interventions were mapped to the developed taxonomy based on their categories, components, and outcomes. Distributions of components by category and study year were graphically presented.ResultsNinety studies (25 randomized, 23 high quality) were included. Six intervention categories were identified: advance care planning; palliative and end-of-life care; onsite care for acute, subacute, or uncontrolled chronic conditions; transitional care; enhanced usual care (most prevalent, 31% of 90 interventions); and comprehensive care. Four components were identified: increasing human resource capacity (most prevalent, 93%), training or reorganization of existing staff, technology, and standardized tools. The use of technology increased over time. Potentially avoidable ED transfers and/or hospitalizations were measured infrequently as primary outcomes.Conclusions and ImplicationsThis proposed taxonomy can guide future intervention designs. It can also facilitate systematic reviews and precise effect size estimations for homogenous interventions when outcomes are comparable.     

Development and Validation of a Nomogram for Predicting the 6-Year Risk of Cognitive Impairment Among Chinese Older Adults

ObjectiveAlthough some people with mild cognitive impairment may not suffer from dementia lifelong, about 5% of them will progress to dementia within 1 year in community settings. However, a general tool for predicting the risk of cognitive impairment was not adequately studied among older adults.DesignProspective cohort study.SettingCommunity-living, older adults from 22 provinces in China.ParticipantsWe included 10,066 older adults aged 65 years and above (mean age, 83.2 ± 11.1 years), with normal cognition at baseline in the 2002–2008 cohort and 9354 older adults (mean age, 83.5 ± 10.8 years) in the 2008–2014 cohort of the Chinese Longitudinal Healthy Longevity Survey.MethodsWe measured cognitive function using the Chinese version of the Mini-Mental State Examination. Demographic, medical, and lifestyle information was used to develop the nomogram via a Lasso selection procedure using a Cox proportional hazards regression model. We validated the nomogram internally with 2000 bootstrap resamples and externally in a later cohort. The predictive accuracy and discriminative ability of the nomogram were measured by area-under-the-curves and calibration curves, respectively.ResultsEight factors were identified with which to construct the nomogram: age, baseline of the Mini-Mental State Examination, activities of daily living and instrumental activities of daily living score, chewing ability, visual function, history of stroke, watching TV or listening to the radio, and growing flowers or raising pets. The area-under-the-curves for internal and external validation were 0.891 and 0.867, respectively, for predicting incident cognitive impairment. The calibration curves showed good consistency between nomogram-based predictions and observations.Conclusions and ImplicationsThe nomogram-based prediction yielded consistent results in 2 separate large cohorts. This feasible prognostic nomogram constructed using readily ascertained information may assist public health practitioners or physicians to provide preventive interventions of cognitive impairment.     

What Do We Know About Knowledge Translation in the Care of Older Adults? A Scoping Review

ObjectivesThe recent emphasis on knowledge translation (KT) in health care is based on the premise that quality of care improves when research findings are translated into practice. This study aimed to identify the extent, nature, and settings of KT research pertaining to the care of older adults.Design and MethodsWe searched Medline, CINAHL, The Cochrane Library, and EMBASE for systematic reviews related to KT using the terms knowledge translation, research use, evidence-based practice, clinical practice guidelines, or diffusion of innovations. Then we searched the systematic reviews to identify included articles related to older adults. We used quantitative content analysis to summarize the information.ResultsTwo of the 53 systematic reviews about KT focused on the care of older adults. One examined the impact of quality systems on care processes and outcomes for long term care residents. The other studied the effectiveness of active-mode learning programs on physician behavior. Sixty-one of the 1709 primary research articles (3.6%) pertained to the care of older adults. Thirty of these were conducted in long term care facilities, 26 in outpatient clinics, 2 in hospitals, and 3 in multiple settings. Most studies focused on KT interventions targeting professionals (eg, prescribing medications). Organizational interventions (eg, modifying roles) were few; financial and regulatory interventions were rare.ConclusionWe identified a gap in KT research pertaining to the care of older adults. KT intervention research focusing on organizational, financial, and regulatory areas is warranted. The connection between geriatrics and KT is fertile ground for future research.     

Social Isolation and Self-Reported Cognitive Decline Among Older Adults in Japan: A Longitudinal Study in the COVID-19 Pandemic

ObjectivesWe aimed to examine the association between the transition to social isolation and cognitive decline in older adults during the coronavirus disease 2019 (COVID-19) pandemic.DesignLongitudinal study.Setting and ParticipantsThe study included participants from a community in a semiurban area of Japan. We conducted a mailed questionnaire survey of 2000 noninstitutionalized older adults who were randomly sampled. Of those who completed both the baseline and follow-up surveys in March and October 2020, respectively, participants aged ≥70 years without cognitive impairment at baseline were included in the analysis.MethodsParticipants were classified into 4 groups based on their baseline and follow-up social isolation status, which were as follows: “remained nonisolated,” “isolated from nonisolation,” “nonisolated from isolation,” and “consistent isolation.” Self-reported cognitive function was assessed using the Cognitive Performance Scale, and level 2 (mild impairment) or higher (moderate to severe impairment) was defined as cognitive impairment.ResultsUltimately, 955 older adults were analyzed. The mean age of the participants was 79.6 years (standard deviation = 4.7) and 54.7% were women. During the follow-up period, 54 (5.7%) participants developed cognitive impairment. Multivariable logistic regression analysis revealed that compared with the group that remained nonisolated, the isolated from nonisolation and consistent isolation groups were significantly associated with the onset of cognitive impairment [isolated from nonisolation: odds ratio (OR) = 2.74, 95% confidence interval (CI) = 1.13-6.61, P = .026; consistent isolation: OR = 2.33, 95% CI = 1.07-5.05, P = .033].Conclusions and ImplicationsSocial isolation during the COVID-19 pandemic was associated with a decline in cognitive function among older adults. Attention to the social isolation process during the pandemic may be necessary to protect older adults’ cognitive health.     

Translating Evidence-Based Physical Activity Interventions for Frail Elders

SUMMARY

The population shift to an older America has initiated a great deal of interest in the impact of evidence-based physical activity interventions on older adults. Physical activity for older adults has tremendous benefits and is recognized as one of the most powerful health interventions for improving seniors' ability to function and remain independent in the face of active health problems and yet the majority of all older adults remain largely sedentary. To date, few programs have been developed that apply these important research findings in physical activity to frail older adults living in the community. The purpose of this article is to review past and current trends addressing increasing physical activity in the frail elderly population at home. An exemplary model of integrating an evidence-based intervention into community-based care management programs is described. Barriers encountered when implementing evidence-based physical activity interventions with frail elderly at home and recommendations for future work in this area are discussed.     

The Compliance of End-of-Life Care Preferences Among Older Adults and Its Facilitators and Barriers: A Scoping Review

ObjectivesTo explore the compliance of end-of-life (EOL) care preferences, and the facilitators and barriers of promoting quality of EOL care among older adults.DesignA scoping review was used to identify key themes in the compliance of EOL care preferences among older adults.Setting and participantsStudies published between 2009 and 2020 were identified from the Medline and Cochrane libraries. Eligible articles containing components related to the compliance of EOL care preferences among older adults were selected.MeasuresThe eligible articles were thematically synthesized. Factors that affected the compliance of EOL care preferences among older adults were identified from the key components.ResultsIn total, 35 articles were included to identify the key components in the compliance of EOL care preferences: (1) supportive policy, (2) supportive environment, (3) cultural characteristics, (4) advance care planning (ACP), (5) the concordance of EOL care preferences between patients and surrogate decision makers, (6) prognosis awareness, and (7) patient's health status and the type of disease. Facilitators for the compliance of EOL care preferences included enactment of relevant policy, sufficient care institutions, the utilization of ACP, and poor health status. Barriers included lack of supportive policy, different culture, and low utilization of ACP.Conclusions/ImplicationsThe compliance of EOL care preferences was low among older adults. The compliance of EOL care preferences can be improved through relevant policy development and the utilization of ACP.     

Cachexia and Cognitive Function in the Community-Dwelling Older Adults: Mediation Effects of Oral Health

Background

Cognitive impairment and poor oral health are common problems in older adults and are associated with malnutrition. However, it is unclear how they are related to cachexia in community-dwelling older adults. The aim of this study was to examine the relationships among cachexia, cognitive function, and oral health in community-dwelling older adults.

Methods

This study is a secondary analysis of a data-set. Data were collected in the community setting on older adults who applied for government-funded long-term care services in Hong Kong in 2017. Subjects were community-dwelling and aged ≥60 years. The outcome variable was cachexia. The predictors were cognitive function and oral health. The covariates included demographics and comorbidities associated with cachexia or malnutrition. Path analysis was employed to examine the associations among cachexia, cognitive function, and oral health using the software SAS/STAT and Mplus.

Results

This analysis included 12,940 subjects. The prevalence of cachexia was 1.3%. Cognitive function was also found to have a direct effect on the oral health indicators of chewing problems (OR=1.073, p<0.001), brushing teeth problems (OR=1.349, p<0.001), and swallowing problems (coeff.=0.177, p<0.001). Oral health indicators with a direct effect on cachexia included dry mouth (OR=1.250, p<0.001), brushing teeth problems (OR = 1.185, p<0.01), and swallowing problems (OR=1.231, p<0.001). Cognitive function had no significant direct effect, but had a significant indirect effect on cachexia (OR=1.100, p<0.001) which is mediated by brushing teeth problems (OR=1.052, p<0.001) and swallowing problems (OR=1.038, p<0.001).

Conclusion

Cognitive impairment causes cachexia indirectly through poor oral health. This study recommends adding cognitive function when screening community-dwelling older adults for cachexia. Health policymakers should stress regular oral health screening and interventions, and encourage increased utilization of oral health services by community-dwelling older adults with cognitive problems.

     

More than cost‐effectiveness? Applying a second‐stage filter to improve policy decision making

BackgroundApart from cost‐effectiveness, considerations like equity and acceptability may affect health‐care priority setting. Preferably, priority setting combines evidence evaluation with an appraisal procedure, to elicit and weigh these considerations.ObjectiveTo demonstrate a structured approach for eliciting and evaluating a broad range of assessment criteria, including key stakeholders’ values, aiming to support decision makers in priority setting.MethodsFor a set of cost‐effective substitute interventions for depression care, the appraisal criteria were adopted from the Australian Assessing Cost‐Effectiveness initiative. All substitute interventions were assessed in an appraisal, using focus group discussions and semi‐structured interviews conducted among key stakeholders.ResultsAppraisal of the substitute cost‐effective interventions yielded an overview of considerations and an overall recommendation for decision makers. Two out of the thirteen pairs were deemed acceptable and realistic, that is investment in therapist‐guided and Internet‐based cognitive behavioural therapy instead of cognitive behavioural therapy in mild depression, and investment in combination therapy rather than individual psychotherapy in severe depression. In the remaining substitution pairs, substantive issues affected acceptability. The key issues identified were as follows: workforce capacity, lack of stakeholder support and the need for change in clinicians’ attitude.ConclusionsSystematic identification of stakeholders’ considerations allows decision makers to prioritize among cost‐effective policy options. Moreover, this approach entails an explicit and transparent priority‐setting procedure and provides insights into the intended and unintended consequences of using a certain health technology.Patient contributionPatients were involved in the conduct of the study for instance, by sharing their values regarding considerations relevant for priority setting.     

Sarcopenia Is Associated with Cognitive Impairment in Older Adults: A Systematic Review and Meta-Analysis

Background and Objectives

There is little evidence in the literature about the possible relationship between sarcopenia and cognition in older adults. Our objective was to investigate the association between cognitive impairment and sarcopenia in older adults living in the community through a systematic review of published studies.

Research Design and Methods

We performed a systematic review with meta-analysis through Pubmed, LILACS, Scielo and Web of Science databases between March 1, 2001 and December 18, 2018. We included longitudinal and cross-sectional studies that evaluated sarcopenia and cognition as a primary objective.

Results

Of the 274 studies identified by the systematic review, 10 were included in qualitative analysis (total of 9,703 participants), and 6 were eligible for the meta-analysis (n = 7,045). Mean prevalence of sarcopenia was 10.5%. Cognitive impairment was observed in 269 participants with sarcopenia (40%), compared with 1,616 in non-sarcopenic participants (25.3%). Sarcopenia was significantly associated with cognitive impairment (pooled OR = 2.50, 95% CI = 1.26–4.92; p = 0.008). Heterogeneity across the studies was high and significant (I² = 84%).

Discussion and Implications

Our analyzes confirmed that sarcopenic older adults presented a higher prevalence of cognitive impairment. Sarcopenia may represent a risk factor for cognitive decline, but longitudinal studies are needed to explore causality.
