Barriers to implementation of case management for patients with dementia: a systematic mixed studies review

Using qualitative comparative analysis as a mixed methods synthesis in systematic mixed studies reviews: Guidance and a worked example

Qualitative comparative analysis (QCA) is a hybrid method designed to bridge the gap between qualitative and quantitative research in a case-sensitive approach that considers each case holistically as a complex configuration of conditions and outcomes. QCA allows for multiple conjunctural causation, implying that it is often a combination of conditions that produces an outcome, that multiple pathways may lead to the same outcome, and that in different contexts, the same condition may have a different impact on the outcome. This approach to complexity allows QCA to provide a practical understanding for complex, real-world situations, and the context of implementing interventions. There are guides for conducting QCA in primary research and quantitative systematic reviews yet, to our knowledge, no guidance for conducting QCA in systematic mixed studies reviews (SMSRs). Thus, the specific objectives of this paper are to (1) describe a step-by-step approach for novice researchers for using QCA to integrate qualitative and quantitative evidence, including guidance on how to use software; (2) highlight specific challenges; (3) propose potential solutions from a worked example; and (4) provide recommendations for reporting.

Collaborative Care Models of Primary Care Clinics for People with Early-Stage Dementia: A Cross-Sectional Survey of Primary Care Physicians in Japan

Objectives

This study explored collaboration models between primary care physicians (PCPs) and care managers (CMs) and assessed each model's potential in meeting the support needs of individuals with early-stage dementia.

Methods

In 2022, a cross-sectional survey was conducted among the PCPs in Tokyo. The data regarding the participant and clinic characteristics and daily practices for individuals with early-stage dementia were collected. The clinical collaborative practice was classified using a latent class analysis; comparisons were made between the identified classes based on 14 items in seven domains of support.

Results

Two collaborative and one stand-alone models were identified. The former varied in the professionals' roles, with one led by PCPs and the other by CMs. We named them PCP-led, CM-led, and stand-alone models, accounting for 46.4%, 32.8%, and 20.6% of the clinics, respectively. The PCP-led clinics were significantly more likely to provide support than the stand-alone ones across five domains: cognitive function, care planning, carers' support, information, and social health. The CM-led model clinics generally fell between those of the other two models.

Conclusion

Different leadership styles exist in the PCP-CM collaborations in care delivery for people with early-stage dementia. This collaboration offers distinct advantages for clinics in addressing their needs.

Primary care family physicians' experiences with clinical integration in qualitative and mixed reviews: a systematic review protocol

INTRODUCTION

Clinical (service) integration in primary care settings describes how comprehensive care is coordinated by family physicians (FPs) over time across healthcare contexts to meet patient care needs. To improve care integration and healthcare service planning, a systematic approach to understanding its numerous influencing factors is paramount. The objective of this study is to generate a comprehensive map of FP-perceived factors influencing clinical integration across diseases and patient demographics.

METHODS AND ANALYSIS

We developed the protocol with the guidance of the Joanna Briggs Institute systematic review methodology framework. An information specialist built search strategies for MEDLINE, EMBASE and CINAHL databases using keywords and MeSH terms iteratively collected from a multidisciplinary team. Two reviewers will work independently throughout the study process, from article selection to data analysis. The identified records will be screened by title and abstract and reviewed in the full text against the criteria: FP in primary care (population), clinical integration (concept) and qualitative and mixed reviews published in 2011-2021 (context). We will first describe the characteristics of the review studies. Then, we will extract qualitative, FP-perceived factors and group them by content similarities, such as patient factors. Lastly, we will describe the types of extracted factors using a custom framework.

ETHICS AND DISSEMINATION

Ethics approval is not required for a systematic review. The identified factors will help generate an item bank for a survey that will be developed in the Phase II study to ascertain high-impact factors for intervention(s), as well as evidence gaps to guide future research. We will share the study findings with various knowledge users to promote awareness of clinical integration issues through multiple channels: publications and conferences for researchers and care providers, an executive summary for clinical leaders and policy-makers, and social media for the public.

Implementation analysis of a case management intervention for people with complex care needs in primary care: a multiple case study across Canada

BACKGROUND

Case management is one of the most frequently performed interventions to mitigate the negative effects of high healthcare use on patients, primary care providers and the healthcare system. Reviews have addressed factors influencing case management interventions (CMI) implementation and reported common themes related to the case manager role and activities, collaboration with other primary care providers, CMI training and relationships with the patients. However, the heterogeneity of the settings in which CMI have been implemented may impair the transferability of the findings. Moreover, the underlying factors influencing the first steps of CMI implementation need to be further assessed. This study aimed to evaluate facilitators and barriers of the first implementation steps of a CMI by primary care nurses for people with complex care needs who frequently use healthcare services.

METHODS

A qualitative multiple case study was conducted including six primary care clinics across four provinces in Canada. In-depth interviews and focus groups with nurse case managers, health services managers, and other primary care providers were conducted. Field notes also formed part of the data. A mixed thematic analysis, deductive and inductive, was carried out.

RESULTS

Leadership of the primary care providers and managers facilitated the first steps of the of CMI implementation, as did the experience and skills of the nurse case managers and capacity development within the teams. The time required to establish CMI was a barrier at the beginning of the CMI implementation. Most nurse case managers expressed apprehension about developing an "individualized services plan" with multiple health professionals and the patient. Clinic team meetings and a nurse case managers community of practice created opportunities to address primary care providers' concerns. Participants generally perceived the CMI as a comprehensive, adaptable, and organized approach to care, providing more resources and support for patients and better coordination in primary care.

CONCLUSION

Results of this study will be useful for decision makers, care providers, patients and researchers who are considering the implementation of CMI in primary care. Providing knowledge about first steps of CMI implementation will also help inform policies and best practices.

Collaboration and coordination of health and care services for older people with dementia by multidisciplinary health and care providers: a scoping review protocol

INTRODUCTION

Collaboration and coordination of health and care services are key to catering for the diverse needs of a growing population of older people with dementia. When multidisciplinary health and care providers work together, they have the possibility to use resources in a fair, accurate and effective way and thereby do the right thing, at the right time, for the right individual. The aim of this scoping review is to map how different care-providing agencies collaborate and coordinate health and care services for older people with dementia.

METHODS AND ANALYSIS

A scoping review will be carried out following the proposed methodology by Joanna Briggs Institute and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Scoping Review Extension guidelines. Systematic searches will be carried out in scientific databases. Studies published within the last 10 years will be included based on certain eligibility criteria. All included studies will be critically appraised using the Research Pyramid. Data from included studies will be charted and subjected to content analysis.

ETHICS AND DISSEMINATION

Ethics approval is not required for scoping reviews. The dissemination of findings will be conducted through conference presentations and publication in international scientific journals.

Decision-making and related outcomes of patients with complex care needs in primary care settings: a systematic literature review with a case-based qualitative synthesis

BACKGROUND

In primary care, patients increasingly face difficult decisions related to complex care needs (multimorbidity, polypharmacy, mental health issues, social vulnerability and structural barriers). There is a need for a pragmatic conceptual model to understand decisional needs among patients with complex care needs and outcomes related to decision. We aimed to identify types of decisional needs among patients with complex care needs, and decision-making configurations of conditions associated with decision outcomes.

METHODS

We conducted a systematic mixed studies review. Two specialized librarians searched five bibliographic databases (Medline, Embase, PsycINFO, CINAHL and SSCI). The search strategy was conducted from inception to December 2017. A team of twenty crowd-reviewers selected empirical studies on: (1) patients with complex care needs; (2) decisional needs; (3) primary care. Two reviewers appraised the quality of included studies using the Mixed Methods Appraisal Tool. We conducted a 2-phase case-based qualitative synthesis framed by the Ottawa Decision Support Framework and Gregor's explicative-predictive theory type. A decisional need case involved: (a) a decision (what), (b) concerning a patient with complex care needs with bio-psycho-social characteristics (who), (c) made independently or in partnership (how), (d) in a specific place and time (where/when), (e) with communication and coordination barriers or facilitators (why), and that (f) influenced actions taken, health or well-being, or decision quality (outcomes).

RESULTS

We included 47 studies. Data sufficiency qualitative criterion was reached. We identified 69 cases (2997 participants across 13 countries) grouped into five types of decisional needs: 'prioritization' (n = 26), 'use of services' (n = 22), 'prescription' (n = 12), 'behavior change' (n = 4) and 'institutionalization' (n = 5). Many decisions were made between clinical encounters in situations of social vulnerability. Patterns of conditions associated with decision outcomes revealed four decision-making configurations: 'well-managed' (n = 13), 'asymmetric encounters' (n = 21), 'self-management by default' (n = 8), and 'chaotic' (n = 27). Shared decision-making was associated with positive outcomes. Negative outcomes were associated with independent decision-making.

CONCLUSION

Our results could extend decision-making models in primary care settings and inform subsequent user-centered design of decision support tools for heterogenous patients with complex care needs.

Case management for people with dementia living at home and their informal caregivers: A scoping review

Case management is a complex intervention aimed at addressing a variety of health needs of people in their social environment. Case management for people with dementia is often poorly defined and insufficiently described. The crucial process steps are often not well understood. We aim to map and compare the key components, processes and contextual factors of case management programmes for dementia and to explore aspects of the interventions' generalisability. Our search covered the databases PubMed, CINAHL, Cochrane and GeroLit, as well as policy papers from international organisations. We included qualitative, quantitative and mixed-methods studies in the English or German language that was published between 1999 and 2020. The programmes were analysed according to programme characteristics, case management intervention and the structural and processing conditions. We identified 67 studies dealing with 25 programmes. Approximately half of the programmes were investigated in randomised controlled trials, two programmes used a mixed-methods design and the remaining were the subject of pre-post cohort studies. Participants in the studies were predominantly dyads of people with dementia and their informal caregivers. About half of the programmes reported a theoretical framework. All the programmes were derived from case management approaches or referred to such approaches. Despite huge differences in implementation, all the programmes covered the case management steps. In 14 out of 25 programmes, case management was carried out without additional intervention, the other programmes provided mainly education and training for informal caregivers. Costs of the case management interventions were stated in more than half of the programmes.The effectiveness and generalisability of dementia-specific case management interventions could be enhanced if the framework introduced in the review was used in the future by policy, practice and research.

The Care Coordinator’s Tasks During the Implementation of an Integrated Care Pathway for Older Patients: A Qualitative Study Based on the French National “Health Pathway of Seniors for Preserved Autonomy” Pilot Program

Background:

Although integrated care and care coordination are known to be beneficial for older adults’ population, the specific tasks of a Care Coordinator (CC) for integrated care pathways for this population have not been studied in detail.

Setting & Subjects:

The French national pilot program PAERPA provided an integrated care pathway for older adults. In North France, a CC was recruited to support patients and professionals.

Objectives:

(i) To analyse the CC’s tasks in an integrated care pathway for older patients, and (ii) to record perceptions on the CC’s tasks among the participating general practitioners (GP) and community pharmacists.

Design & Methods

Qualitative, two-phase study: (i) Task analysis of the CC’s tasks, to compare the planned and actual tasks; (ii) semi-structured interviews among GPs and community pharmacists involved in the pathway.

Results:

(i) The task analysis showed that the CC’s actual tasks differed from planned tasks. The CC was only meant to be involved in the early stages of the process; actually, the CC undertook more or even unforeseen tasks in coordination, communication, and administrative support throughout the care pathways. (ii) The 28 interviewed healthcare professionals considered the CC’s tasks to be essential to the success of pathways. They appreciated the CC’s administrative support. However, CC’s tasks related to interprofessional communication, and patient and family information, were controversially perceived among GPs and pharmacists.

Conclusions:

The CC’s tasks in an integrated care pathway for older adults showed that the CC’s overall workload was greater than expected and appreciated by healthcare professionals.

Case Management Programs for Improving Integrated Care for Frequent Users of Healthcare Services: An Implementation Analysis

INTRODUCTION

Case management programs (CMP) for frequent users of healthcare services presenting complex healthcare needs constitute an effective strategy to improve patient experience of integrated care and to decrease healthcare overuse and cost. This study sought to identify characteristics of these programs, and their implementation contexts, that help to improve patient self-management, experience of integrated care, and healthcare services use.

METHODS

A mixed methods multiple embedded case study design was conducted, with six CMP implemented in six hospitals of a region of Quebec (Canada).

RESULTS

Within-case analysis describes the structural, environmental, organizational, practitioner, patient, and innovation level characteristics of each CMP and their services integration outcomes based on patient experience, self-management and healthcare services use. Cross-case analysis suggests that the skills, leadership and experience of the case manager, providers' access to the individualized services plan, consideration of the needs of the patient and family members, their participation in decision-making, and the self-management approach, impact integrated care and healthcare services use.

CONCLUSION AND DISCUSSION

This study underscores the necessity of an experienced, knowledgeable and well-trained case manager with interpersonal skills to optimize CMP implementation such that patients are more proactive in their care and their outcomes improve.

Lack of Any Caregiving for Those with Dementia

Older adults with significant cognitive impairment require help with activities of daily living. The BASIC-Cognitive Project, set in Nueces County, Texas, is a community-based study examining trends in cognition among Mexican Americans and non-Hispanic Whites. Using cross-sectional data from a cohort study, we found that at least 7% of individuals aged 65 and older with a Montreal Cognitive Assessment (MoCA) score of < 20 (or < 15 for telephone MoCA), did not receive any caregiving help. This conservative estimate highlights an important community need for those with significant cognitive impairment and has implications regarding safety and care for older adults.

The Cultural Diversity of Dementia Patients and Caregivers in Primary Care Case Management: a Pilot Mixed Methods Study

CONTEXT

The Canadian reality of dementia care may be complicated by the cultural diversity of patients and their informal caregivers.

OBJECTIVES

To what extent do needs differ between Canadian- and foreign-born patients and caregivers? What are their experiences with the illness in primary care case management?

METHODS

Mixed methods, sequential explanatory design (a cross-sectional study, followed by a qualitative descriptive study), involving 15 pairs of patients and caregivers.

RESULTS

Foreign-born patients had more needs compared to their Canadian-born counterparts. Foreign-born caregivers reported more stress, more problems, and increased need for services. However, the reported experiences of Canadian- vs. foreign-born individuals were similar.

CONCLUSION

The results remain hypothesis-generating. The present pilot illustrated the suitability of mixed methods to this area of study, which deserves further investigation to better serve all members of a population already vulnerable by age and disease.

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.

Barriers and Facilitators in the Uptake of Integrated Care Pathways for Older Patients by Healthcare Professionals: A Qualitative Analysis of the French National "Health Pathway of Seniors for Preserved Autonomy" Pilot Program: Barriers and Facilitators for Adhesion of Healthcare Professionals in Integrated Care for Older Patients: A Qualitative Assessment Based on the French National Experiment: 'Health Pathway of Seniors for Preserved Autonomy' (PAERPA)

Introduction:

Integrated care is a particularly promising approach in geriatrics – a field in which the medical, psychological and social issues are often complex. The uptake of integrated care by healthcare professionals (HCPs) is essential but varies markedly. The objective of the present study of healthcare professionals was to identify barriers to and facilitators of commitment to integrated care for seniors.

Methods:

We performed a two-step, qualitative study, comprising (i) six qualitative, semi-directive series of interviews with HCPs (hospital practitioners, family physicians, nurses and pharmacists) who agreed or disagreed to take part in the French national “Health Pathway of Seniors for Preserved Autonomy” (PAERPA) pilot program; and (ii) an analysis of the pooled results, in order to identify common concerns among the healthcare professionals.

Results:

We identified four key “barrier” and “facilitator” topics shared by HCPs who had committed to the pilot program and those who had not: (i) awareness of and/or interest in geriatric medicine and team working, (ii) the presence of a care coordinator; (iii) the provision of information about the program and about the patient, and communication between HCPs, and (iv) personal benefits for the HCPs and the patients.

Key conclusions:

The four key topics identified in this large qualitative study of several healthcare professions should be considered during the design and dissemination of integrated care pathways for older patients.

A new kind of gatekeeper: The increasing prevalence of Advanced Practice Nurses as case managers in US hospitals

Case management is a representation of managed care, cost-containment organizational practices in healthcare, where managed care and its constitutive parts are situated against physician autonomy and decision-making. As a professional field, case management has evolved considerably, with the role recently taken up increasingly by Advanced Practice Nurses in various health care settings. We look at this evolution of a relatively new work task for Advanced Practice Nurses using a countervailing powers perspective, which allows us to move beyond discussions of case management effectiveness and best practices, and draw connections to trends in the social organization of healthcare, especially hospitals. We evaluated organizational (hospital-level) and environmental (county and state-level) characteristics associated with hospitals' use of Advanced Practice Nurses as case managers, using data from U.S. community acute care hospitals for 2016-2018, collected from three data sources: American Hospital Association annual survey (AHA), Centers for Medicare and Medicaid Services (CMS), and Area Resource File. Among organizational characteristics, we found that hospitals that are a part of established Accountable Care Organizations (OR = 2.55, p = 0.009; 95% CI = 1.26-5.14) and those that serve higher acuity patients, as indicated by possessing a higher Case Mix Index (OR = 1.32, p = 0.001; 95% CI = 1.13-1.55), were more likely to use Advanced Practice Nurses as case managers. Among environmental characteristics, having higher local Advanced Practice Nurses concentrations (OR = 1.24, p < 0.001; 95% CI = 1.11-1.39) was associated with hospital Advanced Practice Nurses case management service provision. Beyond the health impacts of Covid-19, its associated recession is placing families, governments and insurers under unprecedented financial stress. Governments and insurers alike are looking to reduce costs anywhere possible. This will inevitably result in increasing amounts of managed care, and decreasing reimbursements to hospitals, likely resulting in higher demand for APRN patient navigators.

"It's Tricky": Care Managers' Perspectives on Interacting with Primary Care Clinicians

Care management programs that facilitate collaboration between care managers and primary care clinicians are more likely to be successful in improving chronic disease metrics than programs that do not facilitate such collaboration. The authors sought to understand care managers' perspectives on interacting with primary care clinicians. Semi-structured qualitative interviews were conducted with care managers (n = 29) from 3 health systems in and around a large, urban academic center. Interviews were audio recorded, transcribed verbatim, and iteratively analyzed using a grounded theory approach. Care managers worked for health plans (14%), outpatient specialty clinics (31%), hospitals and emergency departments (24%), and primary care offices (14%). Care managers identified the primary care clinician as leading patients' care and as essential to avoiding unnecessary utilization. Care managers described variability in and barriers to interacting with primary care clinicians. When possible, care managers use the electronic medical record to facilitate interaction rather than communicating directly (eg, phone call) with primary care clinicians. The role of the care manager varied across programs, contributing to primary care clinicians' poor understanding of what the care manager could provide. Consequently, primary care clinicians asked the care manager for help with tasks beyond his/her role. Care managers felt inferior to primary care clinicians, a potential result of the traditional medical hierarchy, which also hindered interactions. Although care managers view interactions with the primary care clinician as essential to the health of the patient, communication challenges, variability of the care manager's role, and medical hierarchy limit collaboration.

Integrated care for the management of ageing-related non-communicable diseases: current gaps and future directions

Due to the increase in the older population in Europe and associated rise in the absolute number of persons with Non-Communicable Diseases (NCDs), it is becoming increasingly important to find ways to promote healthy ageing, which is defined as the process of developing and maintaining the functional ability that enables well-being in older age. Older persons with NCDs can have complex care needs due to the increased risk of frailty, multimorbidity, and polypharmacy. However, current health systems in Europe often provide fragmented care for older people with NCDs; many receive disjointed care from numerous specialists or via different levels of care. In the current article, we discuss barriers and challenges in implementing integrated care models in European settings for older NCD patients. Specifically, we discuss the need for greater use of case managers in the care and treatment persons with complex care needs as well as the lack of training and education in healthcare professionals on topics related to multimorbidity, frailty, and polypharmacy. We discuss the limitations that arise from the current focus on disease-specific guidelines and care models that do not take comorbid conditions into account, and the lack of good quality evidence that evaluates the effectiveness of integrated care interventions, especially in European health settings. We highlight the importance of evaluating and monitoring mental health in conjunction with somatic symptoms in NCD patients and discuss the integral role of information and communication technology in healthcare to streamline integrated care processes and help to achieve better outcomes for patients.

Characteristics of Case Management in Primary Care Associated With Positive Outcomes for Frequent Users of Health Care: A Systematic Review

PURPOSE

Case management (CM) interventions are effective for frequent users of health care services, but little is known about which intervention characteristics lead to positive outcomes. We sought to identify characteristics of CM that yield positive outcomes among frequent users with chronic disease in primary care.

METHODS

For this systematic review of both quantitative and qualitative studies, we searched MEDLINE, CINAHL, Embase, and PsycINFO (1996 to September 2017) and included articles meeting the following criteria: (1)population: adult frequent users with chronic disease, (2)intervention: CM in a primary care setting with a postintervention evaluation, and (3)primary outcomes: integration of services, health care system use, cost, and patient outcome measures. Independent reviewers screened abstracts, read full texts, appraised methodologic quality (Mixed Methods Appraisal Tool), and extracted data from the included studies. Sufficient and necessary CM intervention characteristics were identified using configurational comparative methods.

RESULTS

Of the 10,687 records retrieved, 20 studies were included; 17 quantitative, 2 qualitative, and 1 mixed methods study. Analyses revealed that it is necessary to identify patients most likely to benefit from a CM intervention for CM to produce positive outcomes. High-intensity intervention or the presence of a multidisciplinary/interorganizational care plan was also associated with positive outcomes.

CONCLUSIONS

Policy makers and clinicians should focus on their case-finding processes because this is the essential characteristic of CM effectiveness. In addition, value should be placed on high-intensity CM interventions and developing care plans with multiple types of care providers to help improve patient outcomes.

Impact of health service interventions on acute hospital use in community-dwelling persons with dementia: A systematic literature review and meta-analysis

Background

Persons with dementia have twice the acute hospital use as older persons without dementia. In addition to straining overburdened healthcare systems, acute hospital use impacts patient and caregiver quality of life and is associated with increased risk of adverse outcomes including death. Reducing avoidable acute hospital use in persons with dementia is thus a global healthcare priority. However, evidence regarding the impact of health service interventions as defined by the Effective Practice and Organization of Care Cochrane Group on acute hospital use is scant and inconclusive. The aim of this systematic review and meta-analysis was to synthesize available evidence on the impact of health service interventions on acute hospital use in community-dwelling persons with dementia compared to usual care.

Methods

Data Sources: MEDLINE, EMBASE, CINAHL and Cochrane CENTRAL (from 01/1995 to 08/2017). Study eligibility criteria: Randomised controlled trials measuring the impact of health service interventions on acute hospital use (proportion and mean number of emergency department visits and hospitalisations, mean number of hospital days, measured at 12 months, and at longest follow-up) in community-dwelling persons with dementia, compared to usual care. Study selection, appraisal and synthesis methods: Reviewers independently identified studies, extracted data, and assessed the risk of bias, with the Cochrane risk of bias tool. Authors of relevant trials were queried about unpublished data. Random effects model was used for meta-analyses. Effect heterogeneity was assessed through prediction intervals, and explored using sub-group analyses.

Findings

Seventeen trials provided data on 4,549 persons. Unpublished data were obtained for 13 trials, representing 65% of synthesized data. Most interventions included a case management or a self-management component. None of the outcome comparisons provided conclusive evidence supporting the hypothesis that these interventions would lead to a decrease in acute hospital use. Furthermore, prediction intervals indicated possible and important increased service use associated with these interventions, such as emergency department visits, hospital admissions, and hospital days. Subgroup analyses did not favour any type of intervention. A limitation of this study is the inclusion of any type of health service intervention, which may have increased the observed heterogeneity.

Conclusion

Despite a comprehensive systematic review and meta-analysis, including predominantly unpublished data, no health service intervention beyond usual care was found to reduce acute hospital use in community-dwelling persons with dementia. An important increase in service use may be associated with these interventions. Further research is urgently needed to identify effective interventions for this vulnerable population to limit rising acute hospital use, associated costs and adverse outcomes.

Integrated care for adults with dementia and other cognitive disorders

The importance of better care integration is emphasized in many national dementia plans. The inherent complexity of organizing care for people with dementia provides both the justification for improving care integration and the challenges to achieving it. The prevention, detection, and early diagnosis of cognitive disorders mainly resides in primary care, but how this is best integrated within the range of disorders that primary care clinicians are expected to screen is unclear. Models of integrated community dementia assessment and management have varying degrees of involvement of primary and specialist care, but share an emphasis on improving care coordination, interdisciplinary teamwork, and personalized care. Integrated care strategies in acute care are still in early development, but have been a focus of investigation in the past decade. Integrated care outreach strategies to reduce transfers from long-term residential care to acute care have been consistently effective. Integrated long-term residential care includes considerations of end-of-life care. Future directions should include strategies for training and education, early detection in anticipation of disease modifying treatments, integration of technological developments into dementia care, integration of dementia care into general health and social care, and the encouragement of a dementia-friendly society.

Health care costs of case management for frequent users of the emergency department: Hospital and insurance perspectives

BACKGROUND

In most emergency departments (EDs), few patients account for a relatively high number of ED visits. To improve the management of these patients, the university hospital of Lausanne, Switzerland, implemented an interdisciplinary case management (CM) intervention. This study examined whether the CM intervention-compared with standard care (SC) in the ED-reduced costs generated by frequent ED users, not only from the hospital perspective, but also from the third-party payer perspective, that is, from a broader perspective that takes into account the costs of health care services used outside the hospital offering the intervention.

METHODS

In this randomized controlled trial, 250 frequent ED users (>5 visits during the previous 12 months) were allocated to either the CM or the SC group and followed up for 12 months. Cost data were obtained from the hospital's analytical accounting system for the entire sample and from health insurance companies for a subgroup (n = 140). Descriptive statistics and multivariate regressions were used to make comparisons between groups and assess the contribution of patient characteristics to the main cost components.

RESULTS

At the end of the 12-month follow-up, 115 patients were in the CM group and 115 in the SC group (20 had died). Despite differences in economic costs between patients in the CM intervention and the SC groups, our results do not show any statistically significant reduction in costs associated with the intervention, either for the hospital that housed the intervention or for the third-party payer. Frequent ED users were big users of health services provided by both the hospital and community-based services, with 40% of costs generated outside the hospital that housed the intervention. Higher age, Swiss citizenship, and having social difficulty increased costs significantly.

CONCLUSIONS

As the role of the CM team is to guide patients through the entire care process, the intervention location is not limited to the hospital but often extends into the community.

Roles and Functions of Community Health Workers in Primary Care

Community health workers have potential to enhance primary care access and quality, but remain underutilized. To provide guidance on their integration, we characterized roles and functions of community health workers in primary care through a literature review and synthesis. Analysis of 30 studies identified 12 functions (ie, care coordination, health coaching, social support, health assessment, resource linking, case management, medication management, remote care, follow-up, administration, health education, and literacy support) and 3 prominent roles representing clusters of functions: clinical services, community resource connections, and health education and coaching. We discuss implications for community health worker training and clinical support in primary care.

Integrated care for older populations and its implementation facilitators and barriers: A rapid scoping review

Purpose

Inform health system improvements by summarizing components of integrated care in older populations. Identify key implementation barriers and facilitators.

Data sources

A scoping review was undertaken for evidence from MEDLINE, the Cochrane Library, organizational websites and internet searches. Eligible publications included reviews, reports, individual studies and policy documents published from 2005 to February 2017.

Study selection

Initial eligible documents were reviews or reports concerning integrated care approaches in older/frail populations. Other documents were later sourced to identify and contextualize implementation issues.

Data extraction

Study findings and implementation barriers and facilitators were charted and thematically synthesized.

Results of data synthesis

Thematic synthesis using 30 publications identified 8 important components for integrated care in elderly and frail populations: (i) care continuity/transitions; (ii) enabling policies/governance; (iii) shared values/goals; (iv) person-centred care; (v) multi-/inter-disciplinary services; (vi) effective communication; (vii) case management; (viii) needs assessments for care and discharge planning. Intervention outcomes and implementation issues (barriers or facilitators) tend to depend heavily on the context and programme objectives. Implementation issues in four main areas were observed: (i) Macro-level contextual factors; (ii) Miso-level system organization (funding, leadership, service structure and culture); (iii) Miso-level intervention organization (characteristics, resources and credibility) and (iv) Micro-level factors (shared values, engagement and communication).

Conclusion

Improving integration in care requires many components. However, local barriers and facilitators need to be considered. Changes are expected to occur slowly and are more likely to be successful where elements of integrated care are well incorporated into local settings.

Stakeholders perspectives on the key components of community-based interventions coordinating care in dementia: a qualitative systematic review

BACKGROUND

Interventions aiming to coordinate services for the community-based dementia population vary in components, organisation and implementation. In this review we aimed to investigate the views of stakeholders on the key components of community-based interventions coordinating care in dementia.

METHODS

We searched four databases from inception to June 2015; Medline, The Cochrane Library, EMBASE and PsycINFO, this was aided by a search of four grey literature databases, and backward and forward citation tracking of included papers. Title and abstract screening was followed by a full text screen by two independent reviewers, and quality was assessed using the CASP appraisal tool. We then conducted thematic synthesis on extracted data.

RESULTS

A total of seven papers from five independent studies were included in the review, and encompassed the views of over 100 participants from three countries. Through thematic synthesis we identified 32 initial codes that were grouped into 5 second-order themes: (1) case manager had four associated codes and described preferences for the case manager personal and professional attributes, including a sound knowledge in dementia and availability of local services; (2) communication had five associated codes and emphasized the importance stakeholders placed on multichannel communication with service users, as well as between multidisciplinary teams and across organisations; (3) intervention had 11 associated codes which focused primarily on the practicalities of implementation such as the contact type and frequency between case managers and service users, and the importance of case manager training and service evaluation; (4) resources had five associated codes which outlined stakeholder views on the required resources for coordinating interventions and potential overlap with existing resources, as well as arising issues when available resources do not meet those required for successful implementation; and (5) support had seven associated codes that reflect the importance that was placed on the support network around the case manager and the investment of professionals involved directly in care as well as the wider professional network.

CONCLUSION

The synthesis of relevant qualitative studies has shown how various stakeholder groups considered dementia care coordination interventions to be acceptable, useful and appropriate for dementia care, and have clear preferences for components, implementation methods and settings of these interventions. By incorporating stakeholders' perspectives and preferences when planning and developing coordinating interventions we may increase the likelihood of successful implementation and patient benefits.

Case Managers for High-Risk, High-Cost Patients as Agents and Street-Level Bureaucrats

Case management programs often designate a nurse or social worker to take responsibility for guiding care when patients are expected to be expensive or risk a major decline. We hypothesized that though an intuitively appealing idea, careful program design and faithful implementation are essential if case management programs are to succeed. We employed two theory perspectives, principal-agent framework and street-level bureaucratic theory to describe the relationship between program designers (principals) and case managers (agents/street-level bureaucrats) to review 65 case management studies. Most programs were successful in limited program-specific process and outcome goals. But there was much less success in cost-saving or cost-effectiveness-the original and overarching goal of case management. Cost results might be improved if additional ideas of agency and street-level theory were adopted, specifically, incentives, as well as "green tape," clear rules, guidelines, and algorithms relating to resource allocation among patients.

Development of an optimised key worker framework for people with dementia, their family and caring unit living in the community

Background

In Australia, dementia is a national health priority. With the rising number of people living with dementia and shortage of formal and informal carers predicted in the near future, developing approaches to coordinating services in quality-focused ways is considered an urgent priority. Key worker support models are one approach that have been used to assist people living with dementia and their caring unit coordinate services and navigate service systems; however, there is limited literature outlining comprehensive frameworks for the implementation of community dementia key worker roles in practice. In this paper an optimised key worker framework for people with dementia, their family and caring unit living in the community is developed and presented.

Methods

A number of processes were undertaken to inform the development of a co-designed optimised key worker framework: an expert working and reference group; a systematic review of the literature; and a qualitative evaluation of 14 dementia key worker models operating in Australia involving 14 interviews with organisation managers, 19 with key workers and 15 with people living with dementia and/or their caring unit. Data from the systematic review and evaluation of dementia key worker models were analysed by the researchers and the expert working and reference group using a constant comparative approach to define the essential components of the optimised framework.

Results

The developed framework consisted of four main components: overarching philosophies; organisational context; role definition; and key worker competencies. A number of more clearly defined sub-themes sat under each component. Reflected in the framework is the complexity of the dementia journey and the difficulty in trying to develop a ‘one size fits all’ approach.

Conclusions

This co-designed study led to the development of an evidence based framework which outlines a comprehensive synthesis of components viewed as being essential to the implementation of a dementia key worker model of care in the community. The framework was informed and endorsed by people living with dementia and their caring unit, key workers, managers, Australian industry experts, policy makers and researchers. An evaluation of its effectiveness and relevance for practice within the dementia care space is required.

Organizational interventions improving access to community-based primary health care for vulnerable populations: a scoping review

Access to community-based primary health care (hereafter, 'primary care') is a priority in many countries. Health care systems have emphasized policies that help the community 'get the right service in the right place at the right time'. However, little is known about organizational interventions in primary care that are aimed to improve access for populations in situations of vulnerability (e.g., socioeconomically disadvantaged) and how successful they are. The purpose of this scoping review was to map the existing evidence on organizational interventions that improve access to primary care services for vulnerable populations. Scoping review followed an iterative process. Eligibility criteria: organizational interventions in Organisation for Economic Cooperation and Development (OECD) countries; aiming to improve access to primary care for vulnerable populations; all study designs; published from 2000 in English or French; reporting at least one outcome (avoidable hospitalization, emergency department admission, or unmet health care needs).

SOURCES

Main bibliographic databases (Medline, Embase, CINAHL) and team members' personal files.

STUDY SELECTION

One researcher selected relevant abstracts and full text papers. Theory-driven synthesis: The researcher classified included studies using (i) the 'Patient Centered Access to Healthcare' conceptual framework (dimensions and outcomes of access to primary care), and (ii) the classification of interventions of the Cochrane Effective Practice and Organization of Care. Using pattern analysis, interventions were mapped in accordance with the presence/absence of 'dimension-outcome' patterns. Out of 8,694 records (title/abstract), 39 studies with varying designs were included. The analysis revealed the following pattern. Results of 10 studies on interventions classified as 'Formal integration of services' suggested that these interventions were associated with three dimensions of access (approachability, availability and affordability) and reduction of hospitalizations (four/four studies), emergency department admissions (six/six studies), and unmet healthcare needs (five/six studies). These 10 studies included seven non-randomized studies, one randomized controlled trial, one quantitative descriptive study, and one mixed methods study. Our results suggest the limited breadth of research in this area, and that it will be feasible to conduct a full systematic review of studies on the effectiveness of the formal integration of services to improve access to primary care services for vulnerable populations.

Family Physician-Case Manager Collaboration and Needs of Patients With Dementia and Their Caregivers: A Systematic Mixed Studies Review

PURPOSE

Dementia case management (CM) in primary care is a complex intervention aimed at identifying the various needs of patients with dementia and their caregivers, as well as the organization and coordination of care. A key element of CM is the collaboration of family physicians with case managers. We conducted a systematic mixed-studies review to identify the needs of the patient-caregiver dyad and the effects of CM.

METHODS

We searched MEDLINE, PsycINFO, and EMBASE up to October 2014, regardless of the study design. Our main outcomes were needs of patients and their caregivers and the effects of CM on these needs. We used narrative syntheses to develop a taxonomy of needs and to describe the effects of CM on those needs. We used meta-analysis to calculate the prevalence of needs and the standardized mean differences to evaluate the effects of CM on the needs identified.

RESULTS

Fifty-four studies were included. We identified needs of the patient-caregiver dyad and needs of the patient and caregiver individually. CM addressed the majority of the identified needs. Still, some very common needs (eg, early diagnosis) are overlooked while other needs (eg, education on the disease) are well addressed. Fully establishing the value of CM is difficult given the small number of studies of CM in primary care.

CONCLUSIONS

There is good evidence that case managers, in collaboration with family physicians, have a pivotal role in addressing the needs of the patient-caregiver dyad.

Factors facilitating dementia case management: Results of online focus groups

To obtain insight into facilitating factors for case management in dementia care, we conducted a qualitative study with 13 online focus groups (OFGs). Participants were professionals involved in dementia case management ( N = 99). We used mind-maps and the method of constant comparison for analysis. Participants perceived OFGs as a useful tool to explore their perspectives. The perceived advantage of OFGs was the flexibility and convenience of logging in at any time or place preferred. Five facilitating factors for case management were identified in the OFGs: 1. Good cooperation between partners; 2. Organisational embedding with an independent position of case managers; 3. Structural funding; 4. Competent case managers; 5. Familiarity with case management in the region. Good cooperation was essential for successful dementia case management and should thus be a primary concern for care providers.

Comorbidity and dementia: a mixed-method study on improving health care for people with dementia (CoDem)

Background

Among people living with dementia (PLWD) there is a high prevalence of comorbid medical conditions but little is known about the effects of comorbidity on processes and quality of care and patient needs or how services are adapting to address the particular needs of this population.

Objectives

To explore the impact of dementia on access to non-dementia services and identify ways of improving the integration of services for this population.

Design

We undertook a scoping review, cross-sectional analysis of a population cohort database, interviews with PLWD and comorbidity and their family carers and focus groups or interviews with health-care professionals (HCPs). We focused specifically on three conditions: diabetes, stroke and vision impairment (VI). The analysis was informed by theories of continuity of care and access to care.

Participants

The study included 28 community-dwelling PLWD with one of our target comorbidities, 33 family carers and 56 HCPs specialising in diabetes, stroke, VI or primary care.

Results

The scoping review (n = 76 studies or reports) found a lack of continuity in health-care systems for PLWD and comorbidity, with little integration or communication between different teams and specialities. PLWD had poorer access to services than those without dementia. Analysis of a population cohort database found that 17% of PLWD had diabetes, 18% had had a stroke and 17% had some form of VI. There has been an increase in the use of unpaid care for PLWD and comorbidity over the last decade. Our qualitative data supported the findings of the scoping review: communication was often poor, with an absence of a standardised approach to sharing information about a person’s dementia and how it might affect the management of other conditions. Although HCPs acknowledged the vital role that family carers play in managing health-care conditions of PLWD and facilitating continuity and access to care, this recognition did not translate into their routine involvement in appointments or decision-making about their family member. Although we found examples of good practice, these tended to be about the behaviour of individual practitioners rather than system-based approaches; current systems may unintentionally block access to care for PLWD. Pathways and guidelines for our three target conditions do not address the possibility of a dementia diagnosis or provide decision-making support for practitioners trying to weigh up the risks and benefits of treatment for PLWD.

Conclusions

Significant numbers of PLWD have comorbid conditions such as stroke, diabetes and VI. The presence of dementia complicates the delivery of health and social care and magnifies the difficulties that people with long-term conditions experience. Key elements of good care for PLWD and comorbidity include having the PLWD and family carer at the centre, flexibility around processes and good communication which ensures that all services are aware when someone has a diagnosis of dementia. The impact of a diagnosis of dementia on pre-existing conditions should be incorporated into guidelines and care planning. Future work needs to focus on the development and evaluation of interventions to improve continuity of care and access to services for PLWD with comorbidity.

Key components in models of community-based interventions coordinating care in dementia: a mixed studies systematic review protocol

BACKGROUND

Current health and social care systems are providing suboptimal and fragmented care to the growing dementia population. Interventions aiming to coordinate care services for individuals with dementia and their families are already widely used; however, the structure and implementation of these interventions vary. This mixed studies review aims to investigate the key components of effective community-based interventions that focus on coordinating care in dementia.

METHODS

We will search MEDLINE, Cochrane Library, Embase and PsycINFO databases for studies of any design that look at community-based interventions that aim to coordinate dementia care through the allocation of a specified professional responsible for provision of care. Health Management Information Consortium (HMIC), Social Policy and Practice (SPP), ProQuest and International Clinical Trials Registry Platform (ICTRP) databases will be searched for grey literature. Outcomes of interest are health outcome measures that relate to the individual with dementia and/or informal caregiver, measures of resource use or process measures. Two independent reviewers will screen identified papers and extract data from eligible studies. Evidence synthesis will take place in three stages, and methods will be largely dependent on the data available. A sequential review design will be used where the qualitative evidence will be synthesised first, focusing on stakeholder's subjective views of key components. This will drive forward the quantitative stage which will identify key components of effective interventions. The final stage of the review will merge the two strands of evidence through a narrative synthesis.

DISCUSSION

The results from this review will be used to develop a model for a community-based intervention coordinating care in dementia. Furthermore, the findings will help guide future work on intervention development of health and social care services for dementia.

Successful collaboration in dementia care from the perspectives of healthcare professionals and informal carers in Germany: results from a focus group study

BACKGROUND

Informal carers of persons with dementia are in contact with numerous healthcare professionals (HCP) in a complex healthcare system. Successful collaboration between the parties involved appears to be essential for good dementia care. Thus, we investigated the perceptions of both HCP and informal carers regarding successful collaboration and sought to describe obstacles and facilitators.

METHODS

As part of the 7(th) framework EU project RightTimePlaceCare, five focus groups were conducted with HCP and informal carers of persons with dementia in Germany (n = 30 participants/ time: Oct/Nov 2011). A supplementary secondary data analysis was performed, applying qualitative content analysis with open coding.

RESULTS

The derived categories were sorted into three overarching themes: collaboration between HCP and informal carers, collaboration among HCP and the impact of resources and healthcare system. HCP and informal carers largely agree on what facilitates or impedes successful collaboration between them. Making the initial contact appears to be a major challenge. While HCP expect to be contacted, informal carers hesitate to seek assistance, primarily due to inner barriers. Permanent contact person/institution, well-trained, empathetic HCP who can establish a trustful relationship are regarded as facilitating collaboration. The relational perspective is more clearly emphasised by HCP than by informal carers. This may be attributed to the absence of a permanent contact person in Germany. Sufficient information relay, clear responsibilities, motivation and defined aims, and a personal relationship between professionals are mentioned as facilitators. External factors, such as rapid staff turnover, insufficient time resources and conditions specified by the health and long-term care system causing financial competition between providers, are described as general barriers to successful collaboration.

CONCLUSIONS

HCP and informal carers had comparable perceptions of successful collaboration among them. The initial contact seems to be particularly challenging. Better strategies are urgently needed to facilitate the access to professional support. A permanent contact person (e.g., a case manager) might improve collaboration among all the parties involved, but this is not available regularly. Constraints created by the healthcare system may considerably hinder successful collaboration.
