Supporting family carers of community-dwelling elder with cognitive decline: a randomized controlled trial

Insights and recommendations for working collaboratively and improving care in Alzheimer's disease: Learnings from the Finding Alzheimer's Solutions Together (F.A.S.T.) Council

BACKGROUND

Collaborations between patient organisations (POs) and the pharmaceutical industry can help identify and address the unmet needs of people living with a disease. In Alzheimer's disease (AD), the scale and complexity of the current unmet needs call for a broad and cross-sectoral collaboration, including people living with Alzheimer's (PLWA), their care partners and the wider research community.

OBJECTIVE

This study aimed to describe learnings from the Finding Alzheimer's Solutions Together (F.A.S.T.) Council, a collaboration between POs and Roche, convened to better understand the unmet needs of PLWA and their care partners.

RESULTS

1. Learnings from the collaboration, including clarifying objectives and members' expectations upfront, and establishing a set of guiding values and engagement principles. 2. Insights and recommendations for improving care in AD, including a wide range of unmet needs and potential solutions, systematically captured throughout the PLWA journey. These have resulted in several published reports and other outcomes, including (1) 'Portraits of care', highlighting the role of care partners, and the impact of coronavirus disease 2019 on care; (2) Clinical trial guidebook, recommending how PLWA and care partner experience can be incorporated into trial design; (3) 'Commitments Catalogue', highlighting progress by governmental organisations in achieving their commitments; and (4) a report to guide policy on improving diversity, equity and inclusion in clinical trials.

CONCLUSIONS

Close collaboration between POs and the pharmaceutical industry in AD can enable effective research, in which PLWA and care partners are engaged as 'experts through experience' to help identify key unmet needs and co-create solutions with the wider AD research community. This paper and the work undertaken by the F.A.S.T. Council may act as a blueprint for meaningful collaboration between POs and the pharmaceutical industry.

PATIENT OR PUBLIC CONTRIBUTION

The paper reports the collaboration between POs, the F.A.S.T. Council and Roche to progress towards a future in which PLWA can live fulfilling lives with their disease managed well.

Satisfaction with Health Care Interventions among Community Dwelling People with Cognitive Disorders and Their Informal Caregivers-A Systematic Review

Informal caregivers have a leading role when implementing health care services for people with cognitive disorders living at home. This study aims to examine the current evidence for interventions with dual satisfaction with health care services for people with cognitive disorders and their caregivers. Original papers with quantitative and mixed method designs were extracted from two databases, covering years 2009-2018. Thirty-five original papers reported on satisfaction with health care services. The International Classification of Health Interventions (ICHI) was used to classify the interventions. Most interventions had a home-based approach (80%). Reduction in caregiver depression was the outcome measure with the highest level of satisfaction. Interventions to reduce depression or increase cognitive performance in persons with cognitive disorders gave the least satisfaction. Satisfaction of both caregivers and persons with cognitive disorders increased their use of services. In the ICHI, nearly 50% of the interventions were classified as activities and participation. A limited number of interventions have a positive effect on satisfaction of both the persons with cognitive disorders and the caregiver. It is important to focus on interventions that will benefit both simultaneously. More research is needed with a clear definition of satisfaction and the use of the ICHI guidelines.

Screening for Cognitive Impairment in Older Adults: Updated Evidence Report and Systematic Review for the US Preventive Services Task Force

IMPORTANCE

Early identification of cognitive impairment may improve patient and caregiver health outcomes.

OBJECTIVE

To systematically review the test accuracy of cognitive screening instruments and benefits and harms of interventions to treat cognitive impairment in older adults (≥65 years) to inform the US Preventive Services Task Force.

DATA SOURCES

MEDLINE, PubMed, PsycINFO, and Cochrane Central Register of Controlled Trials through January 2019, with literature surveillance through November 22, 2019.

STUDY SELECTION

Fair- to good-quality English-language studies of cognitive impairment screening instruments, and pharmacologic and nonpharmacologic treatments aimed at persons with mild cognitive impairment (MCI), mild to moderate dementia, or their caregivers.

DATA EXTRACTION AND SYNTHESIS

Independent critical appraisal and data abstraction; random-effects meta-analyses and qualitative synthesis.

MAIN OUTCOMES AND MEASURES

Sensitivity, specificity; patient, caregiver, and clinician decision-making; patient function, quality of life, and neuropsychiatric symptoms; caregiver burden and well-being.

RESULTS

The review included 287 studies with more than 280 000 older adults. One randomized clinical trial (RCT) (n = 4005) examined the direct effect of screening for cognitive impairment on patient outcomes, including potential harms, finding no significant differences in health-related quality of life at 12 months (effect size, 0.009 [95% CI, -0.063 to 0.080]). Fifty-nine studies (n = 38 531) addressed the accuracy of 49 screening instruments to detect cognitive impairment. The Mini-Mental State Examination was the most-studied instrument, with a pooled sensitivity of 0.89 (95% CI, 0.85 to 0.92) and specificity of 0.89 (95% CI, 0.85 to 0.93) to detect dementia using a cutoff of 23 or less or 24 or less (15 studies, n = 12 796). Two hundred twenty-four RCTs and 3 observational studies including more than 240 000 patients or caregivers addressed the treatment of MCI or mild to moderate dementia. None of the treatment trials were linked with a screening program; in all cases, participants were persons with known cognitive impairment. Medications approved to treat Alzheimer disease (donepezil, galantamine, rivastigmine, and memantine) improved scores on the ADAS-Cog 11 by 1 to 2.5 points over 3 months to 3 years. Psychoeducation interventions for caregivers resulted in a small benefit for caregiver burden (standardized mean difference, -0.24 [95% CI, -0.36 to -0.13) over 3 to 12 months. Intervention benefits were small and of uncertain clinical importance.

CONCLUSIONS AND RELEVANCE

Screening instruments can adequately detect cognitive impairment. There is no empirical evidence, however, that screening for cognitive impairment improves patient or caregiver outcomes or causes harm. It remains unclear whether interventions for patients or caregivers provide clinically important benefits for older adults with earlier detected cognitive impairment or their caregivers.

Providers' Perspectives on Case Management of a Healthy Start Program: A Qualitative Study

Although Healthy Start case managers recognized the benefits of case management for facilitating optimal service delivery to women and their families, structural factors impact effective implementation. This study investigated case managers' views of 1) the structural challenges faced in implementing case management for program participants, and 2) possible strategies to enhance case management in medical home settings. Two focus groups were conducted separately with case managers from the four program service sites to gain insight into these issues noted above. Each group was co-facilitated by two evaluators using a previously developed semi-structured interview guide. The group discussions were audio recorded and the case managers' comments were transcribed verbatim. Transcripts were analyzed using thematic analysis, a deductive approach. Data were collected in 2013 and analyzed in 2015. Case managers are challenged by externalities (demographic shifts in target populations, poverty); contractual requirements (predefined catchment neighborhoods, caseload); limited support (client incentives, tailored training, and a high staff turnover rate); and logistic difficulties (organizational issues).

Case managers favored measurable deliverables rather than operational work products. A proposed solution to current challenges emphasizes and encourages the iterative learning process and shared decision making between program targets, funders and providers. Case managers are aware of the challenging environment in which they operate for their clients and for themselves. However, future interventions will require clearly identified performance measures and increased systems support.

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.

The Effect of a Personalized Dementia Care Intervention for Caregivers From Australian Minority Groups

Most caregiver interventions in a multicultural society are designed to target caregivers from the mainstream culture and exclude those who are unable to speak English. This study addressed the gap by testing the hypothesis that personalized caregiver support provided by a team led by a care coordinator of the person with dementia would improve competence for caregivers from minority groups in managing dementia. A randomised controlled trial was utilised to test the hypothesis. Sixty-one family caregivers from 10 minority groups completed the trial. Outcome variables were measured prior to the intervention, at 6 and 12 months after the commencement of trial. A linear mixed effect model was used to estimate the effectiveness of the intervention. The intervention group showed a significant increase in the caregivers' sense of competence and mental components of quality of life. There were no significant differences in the caregivers' physical components of quality of life.

Case management approaches to home support for people with dementia

BACKGROUND

Over 35 million people are estimated to be living with dementia in the world and the societal costs are very high. Case management is a widely used and strongly promoted complex intervention for organising and co-ordinating care at the level of the individual, with the aim of providing long-term care for people with dementia in the community as an alternative to early admission to a care home or hospital.

OBJECTIVES

To evaluate the effectiveness of case management approaches to home support for people with dementia, from the perspective of the different people involved (patients, carers, and staff) compared with other forms of treatment, including 'treatment as usual', standard community treatment and other non-case management interventions.

SEARCH METHODS

We searched the following databases up to 31 December 2013: ALOIS, the Specialised Register of the Cochrane Dementia and Cognitive Improvement Group,The Cochrane Library, MEDLINE, EMBASE, PsycINFO, CINAHL, LILACS, Web of Science (including Science Citation Index Expanded (SCI-EXPANDED) and Social Science Citation Index), Campbell Collaboration/SORO database and the Specialised Register of the Cochrane Effective Practice and Organisation of Care Group. We updated this search in March 2014 but results have not yet been incorporated.

SELECTION CRITERIA

We include randomised controlled trials (RCTs) of case management interventions for people with dementia living in the community and their carers. We screened interventions to ensure that they focused on planning and co-ordination of care.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures as required by The Cochrane Collaboration. Two review authors independently extracted data and made 'Risk of bias' assessments using Cochrane criteria. For continuous outcomes, we used the mean difference (MD) or standardised mean difference (SMD) between groups along with its confidence interval (95% CI). We applied a fixed- or random-effects model as appropriate. For binary or dichotomous data, we generated the corresponding odds ratio (OR) with 95% CI. We assessed heterogeneity by the I² statistic.

MAIN RESULTS

We include 13 RCTs involving 9615 participants with dementia in the review. Case management interventions in studies varied. We found low to moderate overall risk of bias; 69% of studies were at high risk for performance bias.The case management group were significantly less likely to be institutionalised (admissions to residential or nursing homes) at six months (OR 0.82, 95% CI 0.69 to 0.98, n = 5741, 6 RCTs, I² = 0%, P = 0.02) and at 18 months (OR 0.25, 95% CI 0.10 to 0.61, n = 363, 4 RCTs, I² = 0%, P = 0.003). However, the effects at 10 - 12 months (OR 0.95, 95% CI 0.83 to 1.08, n = 5990, 9 RCTs, I² = 48%, P = 0.39) and 24 months (OR 1.03, 95% CI 0.52 to 2.03, n = 201, 2 RCTs, I² = 0%, P = 0.94) were uncertain. There was evidence from one trial of a reduction in the number of days per month in a residential home or hospital unit in the case management group at six months (MD -5.80, 95% CI -7.93 to -3.67, n = 88, 1 RCT, P < 0.0001) and at 12 months (MD -7.70, 95% CI -9.38 to -6.02, n = 88, 1 RCT, P < 0.0001). One trial reported the length of time until participants were institutionalised at 12 months and the effects were uncertain (hazard ratio (HR): 0.66, 95% CI 0.38 to 1.14, P = 0.14). There was no difference in the number of people admitted to hospital at six (4 RCTs, 439 participants), 12 (5 RCTs, 585 participants) and 18 months (5 RCTs, 613 participants). For mortality at 4 - 6, 12, 18 - 24 and 36 months, and for participants' or carers' quality of life at 4, 6, 12 and 18 months, there were no significant effects. There was some evidence of benefits in carer burden at six months (SMD -0.07, 95% CI -0.12 to -0.01, n = 4601, 4 RCTs, I² = 26%, P = 0.03) but the effects at 12 or 18 months were uncertain. Additionally, some evidence indicated case management was more effective at reducing behaviour disturbance at 18 months (SMD -0.35, 95% CI -0.63 to -0.07, n = 206, 2 RCTs I² = 0%, P = 0.01) but effects were uncertain at four (2 RCTs), six (4 RCTs) or 12 months (5 RCTs).The case management group showed a small significant improvement in carer depression at 18 months (SMD -0.08, 95% CI -0.16 to -0.01, n = 2888, 3 RCTs, I² = 0%, P = 0.03). Conversely, the case management group showed greater improvement in carer well-being in a single study at six months (MD -2.20 CI CI -4.14 to -0.26, n = 65, 1 RCT, P = 0.03) but the effects were uncertain at 12 or 18 months. There was some evidence that case management reduced the total cost of services at 12 months (SMD -0.07, 95% CI -0.12 to -0.02, n = 5276, 2 RCTs, P = 0.01) and incurred lower dollar expenditure for the total three years (MD= -705.00, 95% CI -1170.31 to -239.69, n = 5170, 1 RCT, P = 0.003). Data on a number of outcomes consistently indicated that the intervention group received significantly more community services.

AUTHORS' CONCLUSIONS

There is some evidence that case management is beneficial at improving some outcomes at certain time points, both in the person with dementia and in their carer. However, there was considerable heterogeneity between the interventions, outcomes measured and time points across the 13 included RCTs. There was some evidence from good-quality studies to suggest that admissions to care homes and overall healthcare costs are reduced in the medium term; however, the results at longer points of follow-up were uncertain. There was not enough evidence to clearly assess whether case management could delay institutionalisation in care homes. There were uncertain results in patient depression, functional abilities and cognition. Further work should be undertaken to investigate what components of case management are associated with improvement in outcomes. Increased consistency in measures of outcome would support future meta-analysis.

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

PURPOSE

Results of case management designed for patients with dementia and their caregivers in community-based primary health care (CBPHC) were inconsistent. Our objective was to identify the relationships between key outcomes of case management and barriers to implementation.

METHODS

We conducted a systematic mixed studies review (including quantitative and qualitative studies). Literature search was performed in MEDLINE, PsycINFO, Embase, and Cochrane Library (1995 up to August 2012). Case management intervention studies were used to assess clinical outcomes for patients, service use, caregiver outcomes, satisfaction, and cost-effectiveness. Qualitative studies were used to examine barriers to case management implementation. Patterns in the relationships between barriers to implementation and outcomes were identified using the configurational comparative method. The quality of studies was assessed using the Mixed Methods Appraisal Tool.

RESULTS

Forty-three studies were selected (31 quantitative and 12 qualitative). Case management had a limited positive effect on behavioral symptoms of dementia and length of hospital stay for patients and on burden and depression for informal caregivers. Interventions that addressed a greater number of barriers to implementation resulted in increased number of positive outcomes. Results suggested that high-intensity case management was necessary and sufficient to produce positive clinical outcomes for patients and to optimize service use. Effective communication within the CBPHC team was necessary and sufficient for positive outcomes for caregivers.

CONCLUSIONS

Clinicians and managers who implement case management in CBPHC should take into account high-intensity case management (small caseload, regular proactive patient follow-up, regular contact between case managers and family physicians) and effective communication between case managers and other CBPHC professionals and services.

Case management for dementia in primary health care: a systematic mixed studies review based on the diffusion of innovation model

Background

The purpose of this study was to examine factors associated with the implementation of case management (CM) interventions in primary health care (PHC) and to develop strategies to enhance its adoption by PHC practices.

Methods

This study was designed as a systematic mixed studies review (including quantitative and qualitative studies) with synthesis based on the diffusion of innovation model. A literature search was performed using MEDLINE, PsycInfo, EMBASE, and the Cochrane Database (1995 to August 2012) to identify quantitative (randomized controlled and nonrandomized) and qualitative studies describing the conditions limiting and facilitating successful CM implementation in PHC. The methodological quality of each included study was assessed using the validated Mixed Methods Appraisal Tool.

Results

Twenty-three studies (eleven quantitative and 12 qualitative) were included. The characteristics of CM that negatively influence implementation are low CM intensity (eg, infrequent follow-up), large caseload (more than 60 patients per full-time case manager), and approach, ie, reactive rather than proactive. Case managers need specific skills to perform their role (eg, good communication skills) and their responsibilities in PHC need to be clearly delineated.

Conclusion

Our systematic review supports a better understanding of factors that can explain inconsistent evidence with regard to the outcomes of dementia CM in PHC. Lastly, strategies are proposed to enhance implementation of dementia CM in PHC.

Nurses’ Experiences of Providing Care to Dementia Patients Through Home Health Care

Most Western countries aim to enable dementia sufferers to live at home for as long as possible. Person centeredness, continuity of care, and competence level are all important for the quality of home health care (HHC). The aim of this qualitative study is to describe staff’s experiences of providing care to home-dwelling dementia clients through HHC services. The study used a phenomenological-hermeneutic interpretation of focus group interviews. This study supports the value of continuous interpersonal relationships in HHC services. The findings show that specialized teams facilitate continuity and person-centered care, and that after training, staff become more holistically oriented, involve clients in daily care, and experience greater job confidence.

Non-specialist health worker interventions for the care of mental, neurological and substance-abuse disorders in low- and middle-income countries

BACKGROUND

Many people with mental, neurological and substance-use disorders (MNS) do not receive health care. Non-specialist health workers (NSHWs) and other professionals with health roles (OPHRs) are a key strategy for closing the treatment gap.

OBJECTIVES

To assess the effect of NSHWs and OPHRs delivering MNS interventions in primary and community health care in low- and middle-income countries.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (including the Cochrane Effective Practice and Organisation of Care (EPOC) Group Specialised Register) (searched 21 June 2012); MEDLINE, OvidSP; MEDLINE In Process & Other Non-Indexed Citations, OvidSP; EMBASE, OvidSP (searched 15 June 2012); CINAHL, EBSCOhost; PsycINFO, OvidSP (searched 18 and 19 June 2012); World Health Organization (WHO) Global Health Library (searched 29 June 2012); LILACS; the International Clinical Trials Registry Platform (WHO); OpenGrey; the metaRegister of Controlled Trials (searched 8 and 9 August 2012); Science Citation Index and Social Sciences Citation Index (ISI Web of Knowledge) (searched 2 October 2012) and reference lists, without language or date restrictions. We contacted authors for additional studies.

SELECTION CRITERIA

Randomised and non-randomised controlled trials, controlled before-and-after studies and interrupted-time-series studies of NSHWs/OPHR-delivered interventions in primary/community health care in low- and middle-income countries, and intended to improve outcomes in people with MNS disorders and in their carers. We defined an NSHW as any professional health worker (e.g. doctors, nurses and social workers) or lay health worker without specialised training in MNS disorders. OPHRs included people outside the health sector (only teachers in this review).

DATA COLLECTION AND ANALYSIS

Review authors double screened, double data-extracted and assessed risk of bias using standard formats. We grouped studies with similar interventions together. Where feasible, we combined data to obtain an overall estimate of effect.

MAIN RESULTS

The 38 included studies were from seven low- and 15 middle-income countries. Twenty-two studies used lay health workers, and most addressed depression or post-traumatic stress disorder (PTSD). The review shows that the use of NSHWs, compared with usual healthcare services: 1. may increase the number of adults who recover from depression or anxiety, or both, two to six months after treatment (prevalence of depression: risk ratio (RR) 0.30, 95% confidence interval (CI) 0.14 to 0.64; low-quality evidence); 2. may slightly reduce symptoms for mothers with perinatal depression (severity of depressive symptoms: standardised mean difference (SMD) -0.42, 95% CI -0.58 to -0.26; low-quality evidence); 3. may slightly reduce the symptoms of adults with PTSD (severity of PTSD symptoms: SMD -0.36, 95% CI -0.67 to -0.05; low-quality evidence); 4. probably slightly improves the symptoms of people with dementia (severity of behavioural symptoms: SMD -0.26, 95% CI -0.60 to 0.08; moderate-quality evidence); 5. probably improves/slightly improves the mental well-being, burden and distress of carers of people with dementia (carer burden: SMD -0.50, 95% CI -0.84 to -0.15; moderate-quality evidence); 6. may decrease the amount of alcohol consumed by people with alcohol-use disorders (drinks/drinking day in last 7 to 30 days: mean difference -1.68, 95% CI -2.79 to -0.57); low-quality evidence).It is uncertain whether lay health workers or teachers reduce PTSD symptoms among children. There were insufficient data to draw conclusions about the cost-effectiveness of using NSHWs or teachers, or about their impact on people with other MNS conditions. In addition, very few studies measured adverse effects of NSHW-led care - such effects could impact on the appropriateness and quality of care.

AUTHORS' CONCLUSIONS

Overall, NSHWs and teachers have some promising benefits in improving people's outcomes for general and perinatal depression, PTSD and alcohol-use disorders, and patient- and carer-outcomes for dementia. However, this evidence is mostly low or very low quality, and for some issues no evidence is available. Therefore, we cannot make conclusions about which specific NSHW-led interventions are more effective.

Peer support for carers: a qualitative investigation of the experiences of carers and peer volunteers

Being a carer of someone with dementia can be rewarding and also challenging. Volunteer peer support schemes for carers are being introduced, little is known about either their impact on carers and volunteers or about volunteers' and carers' experiences. This study investigated peer volunteer and carer recipient experiences of a peer support service. Thematic analysis of 13 in-depth interviews with 9 carers and 4 peer volunteers revealed that peer support helped both carers and peer volunteers through the realization that they were "not alone" in their experiences and emotions. Additional carer benefits included opportunities to talk freely about difficult experiences and learning how others cope. Volunteers found their role rewarding, describing satisfaction from putting their own experiences to good use. These findings highlight the isolation and exclusion experienced by current and former carers of people with dementia and draw attention to the benefits of peer support for both the groups.

Diagnosing dementia: no easy job

Background

From both clinical experience and research we learned that in complex progressive disorders such as dementia, diagnosis includes multiple steps, each with their own clinical and research characteristics.

Discussion

Diagnosing starts with a trigger phase in which the GP gradually realizes that dementia may be emerging. This is followed by a disease-oriented diagnosis and subsequently a care -oriented diagnosis. In parallel the GP should consider the consequences of this process for the caregiver and the interaction between both. As soon as a comprehensive diagnosis and care plan are available, monitoring follows.

Summary

We propose to split the diagnostic process into four diagnostic steps, followed by a monitoring phase. We recommend to include these steps when designing studies on screening, diagnosis and monitoring of patients with dementia and their families.
