Systematic Review Investigating Multi-disciplinary Team Approaches to Screening and Early Diagnosis of Dementia in Primary Care - What are the Positive and Negative Effects and Who Should Deliver It?

Practices and perspectives of primary care physicians in Japan and the United States about diagnosing dementia: a qualitative study

Background

While dementia is a common problem in Japan and the US, primary care physicians' practices and perspectives about diagnosing dementia in these different healthcare systems are unknown.

Methods

Qualitative research was conducted in an ethnographic tradition using semi-structured interviews and thematic analysis in primary care settings across Japan and in the Midwest State of Michigan, US. Participants were a total of 48 primary care physicians, 24 each from Japan and the US participated. Both groups contained a mixture of geographic areas (rural/urban), gender, age, and years of experience as primary care physicians.

Results

Participants in Japan and the US voiced similar practices for making the diagnosis of dementia and held similar views about the desired benefits of diagnosing dementia. Differences were found in attitudes about the appropriate timing of formally diagnosing dementia. Japanese physicians tended to make a formal diagnosis when problems that would benefit from long-term care services emerged for family members. US physicians were more proactive in diagnosing dementia in the early stages by screening for dementia in health check-ups and promoting advance directives when the patients were still capable of decision-making. Views about appropriate timing of diagnostic testing for dementia in the two systems reflect what medical or nursing care services physicians can use to support dementia patients and caregivers.

Conclusions

Benefits of making the diagnosis included the need to activate the long-term care services in Japan and for early intervention and authoring advance directives in the US. Testing to establish an early diagnosis of dementia by primary care physicians only partly relates to testing and treatment options available. Benefits of making the diagnosis included the need to activate the long-term care services in Japan and for early intervention and authoring advance directives in the US.

Optimizing the diagnosis and management of dementia within primary care: a systematic review of systematic reviews

Background

To understand how best to approach dementia care within primary care and its challenges, we examined the evidence related to diagnosing and managing dementia within primary care.

Methods

Databases searched include: MEDLINE, Embase, PsycINFO and The Cochrane Database of Systematic Reviews from inception to 11 May 2020. English-language systematic reviews, either quantitative or qualitative, were included if they described interventions involving the diagnosis, treatment and/or management of dementia within primary care/family medicine and outcome data was available. The risk of bias was assessed using AMSTAR 2. The review followed PRISMA guidelines and is registered with Open Science Framework.

Results

Twenty-one articles are included. The Mini-Cog and the MMSE were the most widely studied cognitive screening tools. The Abbreviated Mental Test Score (AMTS) achieved high sensitivity (100 %, 95 % CI: 70-100 %) and specificity (82 %, 95 % CI: 72-90 %) within the shortest amount of time (3.16 to 5 min) within primary care. Five of six studies found that family physicians had an increased likelihood of suspecting dementia after attending an educational seminar. Case management improved behavioural symptoms, while decreasing hospitalization and emergency visits. The primary care educational intervention, Enhancing Alzheimer’s Caregiver Health (Department of Veterans Affairs), was successful at increasing carer ability to manage problem behaviours and improving outcomes for caregivers.

Conclusions

There are clear tools to help identify cognitive impairment in primary care, but strategies for management require further research. The findings from this systematic review will inform family physicians on how to improve dementia diagnosis and management within their primary care practice.

Systematic review of studies investigating ventilator associated pneumonia diagnostics in intensive care

Background

Ventilator-associated pneumonia (VAP) is an important diagnosis in critical care. VAP research is complicated by the lack of agreed diagnostic criteria and reference standard test criteria. Our aim was to review which reference standard tests are used to evaluate novel index tests for suspected VAP.

Methods

We conducted a comprehensive search using electronic databases and hand reference checks. The Cochrane Library, MEDLINE, CINHAL, EMBASE, and web of science were searched from 2008 until November 2018. All terms related to VAP diagnostics in the intensive treatment unit were used to conduct the search. We adopted a checklist from the critical appraisal skills programme checklist for diagnostic studies to assess the quality of the included studies.

Results

We identified 2441 records, of which 178 were selected for full-text review. Following methodological examination and quality assessment, 44 studies were included in narrative data synthesis. Thirty-two (72.7%) studies utilised a sole microbiological reference standard; the remaining 12 studies utilised a composite reference standard, nine of which included a mandatory microbiological criterion. Histopathological criteria were optional in four studies but mandatory in none.

Conclusions

Nearly all reference standards for VAP used in diagnostic test research required some microbiological confirmation of infection, with BAL culture being the most common reference standard used.

Interest in Dementia Testing

Abstract. Increasing awareness of Alzheimer’s disease and related dementias (ADRD) may contribute to anxiety about the prospect of a dementia-related diagnosis (dementia-related anxiety). In an online study, we examined variables believed to predict interest in ADRD testing: family ADRD history, self-perceived ADRD risk, dementia-related anxiety, and coping styles. Logistic regression analysis indicated family ADRD history, being in a relationship, and greater tendency toward monitoring style of coping were significantly associated with greater likelihood of interest in ADRD testing. In a second model, a significant interaction suggested that greater tendency toward monitoring coping style and greater self-perceived ADRD risk predict greater interest in ADRD testing. In the second model, dementia-related anxiety predicted interest in ADRD testing. Implications and future directions are discussed.

Embarking on a memory assessment voices of older persons living with memory impairment

AIM

To describe older persons who had commenced a memory assessment, experiences of living with memory impairment and related symptoms.

BACKGROUND

Persons with subjective memory impairment are two times more likely to develop dementia over the years than their peers. Older persons seldom seek help from primary health care clinics solely for subjective memory impairment. Of those who seek help, it can take up to 35 months from the person experiencing initial symptoms to referral to a memory clinic. Further research is needed regarding how older persons live with memory impairment with related symptoms before they receive a memory diagnosis.

METHOD

A qualitative study with 23 participants who had commenced a memory assessment in primary care. Semi-structured interviews were held. During the interviews, the Neuropsychiatric Inventory was completed and discussed with the participants. Interview data were analysed using Interpretive Description.

RESULTS

The results are presented under four themes: Conflicting views about the situation, Unveiling the presence of neuropsychiatric symptoms, Compensating with external and internal strategies to recall and Worrying about self and future. Persons with memory impairment were encouraged by family members or others to seek a memory assessment. Few persons were self-referred as memory impairment was often seen as a part of aging. Polarised viewpoints existed within the families regarding the impact of memory impairment on daily life. The presence of neuropsychiatric symptoms appeared unexplored in the participants seeking a memory assessment. In this study, the majority of participants experienced neuropsychiatric symptoms at the time of contact for a memory assessment.

CONCLUSIONS

Memory problems experienced were often viewed by the person as being part of an aging process. The presence of neuropsychiatric symptoms was not acknowledged as being connected to memory impairment. Contextualising 'memory impairment' as a part of a 'cognitive process' may help the person in identifying the presence of neuropsychiatric symptoms.

Intention to undergo dementia screening in primary care settings among community-dwelling older people

To improve the quality of care for people with dementia, several local governments in Japan have implemented a subsidized system for screening of dementia. This cross-sectional study aimed to identify factors that promote public intention to undergo dementia screening. A postal survey was conducted in a residential area that lies across the two cities which started a subsidized system for dementia screening. Semi-structured questionnaires were distributed to community-dwelling people aged ≥65 years; a total of 2269 persons were included in the analysis. χ² test and multiple logistic regression analysis were used to identify factors associated with the willingness to undergo dementia screening. Among the people with dementia, only 28% had undergone a screening test for dementia. The participants who were certified of public long-term care need tended to undergo dementia screening. Approximately 67% of the participants were willing to undergo a dementia diagnosis test. Younger age, female sex, perceived poor health status, having a primary care physician, and independent daily activity level were associated with a greater willingness to undergo dementia screening using a subsidized system. Our study showed that majority of people with possible dementia do not undergo dementia screening. However, majority of people were willing to use a subsidized system for dementia screening. Further studies are required to support the benefits of a subsidized dementia screening in primary care settings. J Am Geriatr Soc 68:-, 2020.

Relational experiences of people seeking help and assessment for subjective cognitive concern and memory loss

Objective: To understand the experience of people who seek help for subjective cognitive concern and memory loss, including people not referred for further assessment. To understand the patients' perspective of the medical process of receiving a cognitive assessment. This work is situated within the context of policy priorities for dementia diagnosis.Methods: Participants with and without dementia were recruited through NHS trusts and community organisations in four regional areas in England. Data were collected using longitudinal qualitative interviews. Transcript data were thematically analysed.Results: Sample of 41 people (mean 75 years, 25 dementia diagnoses). Interpretative thematic analyses focused on the presence or absence of trust in relational experiences. There were three transition points where trust could be specifically developed or undermined: (1) deciding to seek help; (2) healthcare practitioners' response to help-seeking; (3) process and outcome of assessment. Triggers for help-seeking for subjective cognitive concern were being prompted by family and knowing a relative with dementia. When participants perceived healthcare practitioners' behaviour as dismissive, they had less trust in the outcome of the healthcare encounter. Misunderstandings and absence of trust in assessment processes led to participants stating they did not fully agree with the outcomes of the assessment.Conclusions: Healthcare practitioners have an important role in supporting people with subjective cognitive concern ensuring patients have trust in assessment outcomes. Where the validity of the assessment process is seen as ambiguous, people can be left dealing with uncertainty, rather than being clear about ways they can manage their condition, situation or status.

Features of primary care practice influence emergency care-seeking behaviors by caregivers of persons with dementia: A multiple-perspective qualitative study

BACKGROUND

Persons with dementia use emergency department services at rates greater than other older adults. Despite risks associated with emergency department use, persons with dementia and their caregivers often seek emergency services to address needs and symptoms that could be managed within primary care settings. As emergency departments (EDs) are typically sub-optimal environments for addressing dementia-related health issues, facilitating effective primary care provision is critical to reduce the need for, or decision to seek, emergency services. The aim of this study is to explore how features of primary care practice influence care-seeking decisions by community-dwelling persons with dementia and familial caregivers.

METHODS

Semi-structured qualitative interviews were conducted with 27 key dementia-care stakeholders (10 primary care/geriatrics providers, 5 caregivers, 4 emergency medicine physicians, 5 aging service providers, and 3 community paramedics) from multiple health systems. Transcripts from audio recordings were analyzed using a thematic analysis framework to iteratively code and develop emergent themes. Features of primary care were also synthesized into lists of tangible factors leading to emergency care-seeking and those that help prevent (or decrease the need for) ED use.

FINDINGS

Stakeholders identified eight categories of features of primary care encompassing the clinical environment and provision of care. These collapsed into four major themes: (1) clinic and organizational features-including clinic structure and care team staffing; (2) emphasizing proactive approaches to anticipate needs and avoid acute problems-including establishing goals of care, preparing for the future, developing provider-patient/provider-caregiver relationships, and providing caregiver support, education, and resources to help prevent emergencies; (3) health care provider skills and knowledge of dementia-including training and diagnostic capabilities; and (4) engaging appropriate community services/resources to address evolving needs.

CONCLUSIONS

Features of primary care practice influence decisions to seek emergency department care at the system, organizational/clinic, medical, and interpersonal levels, particularly regarding proactive and reactive approaches to addressing dementia-related needs. Interventions for improving primary care for persons with dementia and their caregivers should consider incorporating features that facilitate proactive family-centered dementia care across the four identified themes, and minimize those leading to caregiver decisions to utilize emergency services.
