Key Factors in Helpfulness and Use of the SAFE Intervention for Women Experiencing Intimate Partner Violence and Abuse: Qualitative Outcomes From a Randomized Controlled Trial and Process Evaluation.

BACKGROUND: Many women experience at least one type of intimate partner violence and abuse (IPVA), and although various support options are available, we still know relatively little about web-based interventions for IPVA survivors. We conducted a qualitative evaluation of the SAFE eHealth intervention for women experiencing IPVA in the Netherlands, complementing the quantitative evaluation of self-efficacy, depression, anxiety, and multiple feasibility aspects. OBJECTIVE: This study assessed users' experiences and what, according to them, were useful and helpful aspects of the intervention. METHODS: The intervention consisted of modules with information on relationships and IPVA, help options, physical and mental health, and social support. It also contained interactive elements such as exercises, stories from survivors, a chat, and a forum. A randomized controlled trial was conducted with an intervention arm receiving the complete version of the intervention and a control arm receiving only a static version with the modules on relationships and IPVA and help options. We gathered data through open questions from surveys (for both study arms; n=65) and semistructured interviews (for the intervention study arm; n=10), all conducted on the web, during the randomized controlled trial and process evaluation. Interview data were coded following the principles of open thematic coding, and all qualitative data were analyzed using qualitative content analysis. RESULTS: Overall, most users positively rated the intervention regarding safety, content, and suiting their needs, especially participants from the intervention study arm. The intervention was helpful in the domains of acknowledgment, awareness, and support. However, participants also identified points for improvement: the availability of a simplified version for acute situations; more attention for survivors in the aftermath of ending an abusive relationship; and more information on certain topics, such as technological IPVA, support for children, and legal affairs. Furthermore, although participants expressed a prominent need for interactive contact options such as a chat or forum, the intervention study arm (the only group that had these features at their disposal) mainly used them in a passive way-reading instead of actively joining the conversation. The participants provided various reasons for this passive use. CONCLUSIONS: The positive outcomes of this study are similar to those of other web-based interventions for IPVA survivors, and specific points for improvement were identified. The availability of interactive elements seems to be of added value even when they are used passively. This study provides in-depth insight into the experiences of female IPVA survivors with the SAFE eHealth intervention and makes suggestions for improvements to SAFE and comparable web-based interventions for IPVA as well as inspiring future research. Furthermore, this study shows the importance of a varied assessment of an intervention's effectiveness to understand the real-world impact on its users.

Effectiveness of the SAFE eHealth Intervention for Women Experiencing Intimate Partner Violence and Abuse: Randomized Controlled Trial, Quantitative Process Evaluation, and Open Feasibility Study.

BACKGROUND: Intimate partner violence and abuse (IPVA) is a pervasive societal issue that impacts many women globally. Web-based help options are becoming increasingly available and have the ability to eliminate certain barriers in help seeking for IPVA, especially in improving accessibility. OBJECTIVE: This study focused on the quantitative evaluation of the SAFE eHealth intervention for women IPVA survivors. METHODS: A total of 198 women who experienced IPVA participated in a randomized controlled trial and quantitative process evaluation. Participants were largely recruited on the internet and signed up through self-referral. They were allocated (blinded for the participants) to (1) the intervention group (N=99) with access to a complete version of a help website containing 4 modules on IPVA, support options, mental health, and social support, and with interactive components such as a chat, or (2) the limited-intervention control group (N=99). Data were gathered about self-efficacy, depression, anxiety, and multiple feasibility aspects. The primary outcome was self-efficacy at 6 months. The process evaluation focused on themes, such as ease of use and feeling helped. In an open feasibility study (OFS; N=170), we assessed demand, implementation, and practicality. All data for this study were collected through web-based self-report questionnaires and automatically registered web-based data such as page visits and amount of logins. RESULTS: We found no significant difference over time between groups for self-efficacy, depression, anxiety, fear of partner, awareness, and perceived support. However, both study arms showed significantly decreased scores for anxiety and fear of partner. Most participants in both groups were satisfied, but the intervention group showed significantly higher scores for suitability and feeling helped. However, we encountered high attrition for the follow-up surveys. Furthermore, the intervention was positively evaluated on multiple feasibility aspects. The average amount of logins did not significantly differ between the study arms, but participants in the intervention arm did spend significantly more time on the website. An increase in registrations during the OFS (N=170) was identified: the mean amount of registrations per month was 13.2 during the randomized controlled trial and 56.7 during the OFS. CONCLUSIONS: Our findings did not show a significant difference in outcomes between the extensive SAFE intervention and the limited-intervention control group. It is, however, difficult to quantify the real contribution of the interactive components, as the control group also had access to a limited version of the intervention for ethical reasons. Both groups were satisfied with the intervention they received, with the intervention study arm significantly more so than the control study arm. Integrated and multilayered approaches are needed to aptly quantify the impact of web-based IPVA interventions for survivors.

Optimization of eHealth interventions for intimate partner violence and abuse: A qualitative study amongst Arabic-speaking migrant women.

AIMS: This interview study focuses on the needs and wishes of Arabic-speaking migrant women in the Netherlands to culturally adapt and optimize the digital support platform SAFE (safewomen.nl) for intimate partner violence and abuse (IPVA) for their use. DESIGN: This is a qualitative interview-based study. METHODS: We conducted the study between March 2020 and 2021. The study entailed 16 semi-structured interviews with Arabic-speaking women in the Netherlands with a migration background. RESULTS: Findings suggest that a cultural gap, a lack of knowledge of the Dutch law, and the prevalence of restrictive gender roles amongst the participants and their spouses affected their acknowledgement of the different forms of IPVA. Furthermore, mental health consequences of IPVA were also strongly stigmatized. Clear information in their native language, summarizing infographics and potential interactive features should be main components of any eHealth intervention for this target group. CONCLUSION: The participants in our study deemed e-help a potentially valuable support option for women experiencing IPVA in their community. The impact of IPVA on mental health is currently overlooked within this target group and should be emphasized in future interventions. IMPACT: Cultural sensitivity proved crucial in understanding the concepts of IPVA amongst women with migrant backgrounds. To ensure effective eHealth interventions for migrant women, they should be involved in the design and delivery of these interventions.

Professionals' views on working in the field of domestic violence and abuse during the first wave of COVID-19: a qualitative study in the Netherlands.

BACKGROUND: The COVID-19 pandemic and lockdown evoked great worries among professionals in the field of domestic violence and abuse (DVA) as they expected a rise of the phenomenon. While many countries reported increased DVA, the Netherlands did not. To understand this discrepancy and the overall impact of the lockdown on DVA support services, we interviewed DVA professionals about their experiences with DVA during the rise of COVID-19, the impact of the lockdown on clients and working conditions, and views on eHealth and online tools. METHODS: Semi-structured interviews were conducted among 16 DVA professionals with various specializations. This data was analyzed using open thematic coding and content analysis. RESULTS: Most professionals did not see an increase in DVA reports but they did notice more severe violence. They experienced less opportunities to detect DVA and worried about their clients' wellbeing and the quality of (online) care. Furthermore, their working conditions rapidly changed, with working from home and online, and they expressed frustration, insecurity and loneliness. Professionals feel eHealth and online tools are not always suitable but they do see them as an opportunity to increase reach and maintain services when physical contact is not possible. CONCLUSION: This study suggests DVA was probably under-detected during the lockdown rather than not having increased. The Dutch system heavily relies on professionals to detect and report DVA, suggesting a need for critical evaluation of the accessibility of professional help. Professionals experienced significant challenges and should themselves be supported psychologically and in their changed work practices to maintain their ability to aid survivors.

Improving Prediction of Dementia in Primary Care.

PURPOSE: The Mini-Mental State Examination (MMSE) is one of the most widely used instruments to screen for cognitive deficits; however, this instrument alone is not sensitive enough to detect early symptoms of dementia. We aimed to investigate whether additionally using the Visual Association Test (VAT) improves the predictive value of the MMSE score for development of dementia. METHODS: Analyses were based on data from 2,690 primary care patients aged 70 to 78 years who participated in the Prevention of Dementia by Intensive Vascular Care (preDIVA) trial. We assessed change in the 30-point MMSE score over 2 years and the VAT score at 2 years-dichotomized as perfect (6 points) or imperfect (≤5 points)-and evaluated the predictive values of these tests for a diagnosis of dementia in the subsequent 4 to 6 years. Data were analyzed with logistic regression analysis. RESULTS: Patients having a decline of 2 points or more in total MMSE score over 2 years had an odds ratio of 3.55 (95% CI, 2.51-5.00) for developing dementia. Patients having the same decline in MMSE score plus an imperfect VAT score had an odds ratio of 9.55 (95% CI, 5.89-15.41) for developing dementia. A 1-point decline in MMSE score increased odds of dementia only when the VAT score was imperfect. Dementia risk for patients with a 2- or 3-point decrease in MMSE score and a perfect VAT score did not differ significantly from the average risk of the cohort as a whole. CONCLUSIONS: Administering the VAT in patients with a small decline on the MMSE over a 2-year period has substantial incremental value for identifying those at elevated risk for developing dementia. This simple test may help distinguish older adults who need further cognitive examination from those in whom a watchful waiting policy is justified.

Effectiveness of a 6-year multidomain vascular care intervention to prevent dementia (preDIVA): a cluster-randomised controlled trial.

BACKGROUND: Cardiovascular risk factors are associated with an increased risk of dementia. We assessed whether a multidomain intervention targeting these factors can prevent dementia in a population of community-dwelling older people. METHODS: In this open-label, cluster-randomised controlled trial, we recruited individuals aged 70-78 years through participating general practices in the Netherlands. General practices within each health-care centre were randomly assigned (1:1), via a computer-generated randomisation sequence, to either a 6-year nurse-led, multidomain cardiovascular intervention or control (usual care). The primary outcomes were cumulative incidence of dementia and disability score (Academic Medical Center Linear Disability Score [ALDS]) at 6 years of follow-up. The main secondary outcomes were incident cardiovascular disease and mortality. Outcome assessors were masked to group assignment. Analyses included all participants with available outcome data. This trial is registered with ISRCTN, number ISRCTN29711771. FINDINGS: Between June 7, 2006, and March 12, 2009, 116 general practices (3526 participants) within 26 health-care centres were recruited and randomly assigned: 63 (1890 participants) were assigned to the intervention group and 53 (1636 participants) to the control group. Primary outcome data were obtained for 3454 (98%) participants; median follow-up was 6·7 years (21 341 person-years). Dementia developed in 121 (7%) of 1853 participants in the intervention group and in 112 (7%) of 1601 participants in the control group (hazard ratio [HR] 0·92, 95% CI 0·71-1·19; p=0·54). Mean ALDS scores measured during follow-up did not differ between groups (85·7 [SD 6·8] in the intervention group and 85·7 [7·1] in the control group; adjusted mean difference -0·02, 95% CI -0·38 to 0·42; p=0·93). 309 (16%) of 1885 participants died in the intervention group, compared with 269 (16%) of 1634 participants in the control group (HR 0·98, 95% CI 0·80-1·18; p=0·81). Incident cardiovascular disease did not differ between groups (273 [19%] of 1469 participants in the intervention group and 228 [17%] of 1307 participants in the control group; HR 1·06, 95% CI 0·86-1·31; p=0·57). INTERPRETATION: A nurse-led, multidomain intervention did not result in a reduced incidence of all-cause dementia in an unselected population of older people. This absence of effect might have been caused by modest baseline cardiovascular risks and high standards of usual care. Future studies should assess the efficacy of such interventions in selected populations.

The mediating role of cardiovascular risk factors in the relationship between symptoms of apathy and incident cardiovascular disease in community-dwelling older individuals.

BACKGROUND: In old age, both apathy and depression have been associated with an increased cardiovascular disease (CVD) risk. This study evaluated the mediating role of cardiovascular risk factors in the relationship of apathy and mood symptoms with incident CVD. METHODS: Prospective cohort study of 1,790 community-dwelling older individuals (70-78 years) without a history of CVD or stroke. At baseline, apathy and mood symptoms were assessed with the 15-item Geriatric Depression Scale (GDS-15), of which three items represent apathy symptoms. The mediational risk factors included were diabetes mellitus (DM), body mass index (BMI), current smoking, physical inactivity, systolic blood pressure, and total cholesterol. Incident CVD was evaluated after two years of follow-up. Data were analyzed using structural equation modeling (SEM). RESULTS: Incident CVD occurred in 59 (3.3%) participants. Apathy symptoms had a significant estimated total effect on incident CVD, with increases of 2.2% for each unit increase in apathy score. Of this total effect, 22.7% was due to the mediational effects of physical inactivity (13.6%), current smoking (4.5%), and DM (4.5%). The remaining 77.3% was due to direct effects reflecting other mediational dynamics. No significant (in)direct effects of mood symptoms on incident CVD were found. CONCLUSIONS: Physical inactivity, smoking, and DM account for nearly one-fourth of the variation reflecting the link between apathy symptoms and incident CVD. This illustrates the relevance of unfavorable health behaviors and assessment of DM in older individuals with apathy. The majority of the effect of apathy symptoms on incident CVD is caused by other, yet unknown, factors.

Apathy is an independent risk factor for incident cardiovascular disease in the older individual: a population-based cohort study.

OBJECTIVE: Although depression is considered to be associated with cardiovascular disease (CVD), specifically symptoms of apathy have been strongly associated with a history of CVD in recent studies. In this study, we prospectively assess whether symptoms of apathy and depression are independent risk factors for incident CVD and stroke. METHODS: We carried out a prospective cohort study of 1810 community-dwelling older individuals (70-78 years) without a history of CVD or stroke. Symptoms of apathy and depression were assessed with the 15-item Geriatric Depression Scale. Incident CVD and stroke were assessed after 2 years follow-up. The associations of symptoms of apathy and depression with incident CVD and stroke were analyzed separately using logistic regression analysis. RESULTS: Symptoms of apathy and depression were present in 281 (15.5%) and 266 (14.7%) participants, respectively. Incident CVD occurred in 62 (3.5%) participants and stroke in 55 (3.1%) participants. Apathy was associated with incident CVD after adjustment for demographics and cardiovascular risk factors (odds ratio (OR) = 2.60, 95% CI = 1.46-4.65). Exclusion of subjects with depressive symptoms yielded a similar OR (2.94, 95% CI = 1.45-5.96, n = 1544). No association was found between depressive symptoms and incident CVD. Neither apathy symptoms nor depressive symptoms were associated with incident stroke. CONCLUSIONS: Apathy, but not depression, is a strong, independent risk factor for incident CVD. It may be a marker of underlying vascular disease. By its nature, apathy may cause non-adherence to a healthy lifestyle, diminished activities, and possibly even withdrawal from clinical care aimed at improving vascular risk profiles.

[Why do patients find it difficult to discontinue their medication?] / Waarom vinden patiënten het moeilijk om te stoppen met medicijnen?

Tapering medication is difficult for many patients using chronic medication. Physicians must be aware of why patients experience difficulties in discontinuation. Important are the cognitions of patients about why the medication is necessary, for example because of the deficit of a certain substance that is supplemented by the medication. Or a too favourable expectation of the effect while time-to-benefit has passed. The experience of withdrawal effects during earlier attempts or the experience of dependency hamper new attempts to stop. This is important in medication that induces physical dependency: antipsychotics, antidepressants, benzodiazepines, or proton pump inhibitors. Fear for relapse is also hampering discontinuation; this is at stake in patients with psychosis, depression and epilepsy. Finally, poor communication and not having a trusted professional are impediments for discontinuation. To be successful in helping patients discontinue their medication professionals must communicate well about the patient's personal attitude, experience, emotions, and life circumstances as well as to possess expertise about the technical aspects of the procedure of stopping medication.

[Rational prescription of antidepressants for depression]. / Antidepressiva bij depressie: rationeel voorschrijven.

Antidepressants are the subject of lively public debate. Over one million Dutch people are prescribed an antidepressant each year for a variety of reasons. The number of long-term antidepressant users is smaller, estimated to be around 150,000 patients for over a year for depression. Clinicians and patients together must carefully weigh the pros and cons of antidepressants. In this article, we discuss the latest scientific insights how antidepressants can be used rationally.

Development of a research agenda for general practice based on knowledge gaps identified in Dutch guidelines and input from 48 stakeholders.

BACKGROUND: Several funding organizations using different agendas support research in general practice. Topic selection and prioritization are often not coordinated, which may lead to duplication and research waste. OBJECTIVES: To develop systematically a national research agenda for general practice involving general practitioners, researchers, patients and other relevant stakeholders in healthcare. METHODS: We reviewed knowledge gaps from 90 Dutch general practice guidelines and formulated research questions based on these gaps. In addition, we asked 96 healthcare stakeholders to add research questions relevant for general practice. All research questions were prioritized by practising general practitioners in an online survey (n = 232) and by participants of an invitational conference including general practitioners (n = 48) and representatives of other stakeholders in healthcare (n = 16), e.g. patient organizations and medical specialists. RESULTS: We identified 787 research questions. These were categorized in two ways: according to the chapters of the International Classification for Primary Care (ICPC) and in 12 themes such as common conditions, person-centred care and patient education, collaboration and organization of care. The prioritizing procedure resulted in top 10 lists of research questions for each ICPC chapter and each theme. CONCLUSION: The process resulted in a widely supported National Research Agenda for General Practice. We encourage both researchers and funding organizations to use this agenda to focus their research on the most relevant issues in general practice and to generate new evidence for the next generation of guidelines and the future of general practice.

Lower dementia risk with different classes of antihypertensive medication in older patients.

OBJECTIVE: Use of antihypertensive medication (AHM) is potentially associated with a reduced risk of dementia. Both calcium channel blockers (CCBs) and angiotensin receptor blockers (ARBs) are suggested to have a more pronounced protective effect. We aimed to study the association between different classes of AHM and dementia in older people. METHODS: A subgroup of community-dwelling older people using AHM included in the 'Prevention of Dementia by Intensive Vascular Care' randomized controlled trial was studied. Incident dementia rates in participants with different AHM classes (mono and combination therapy) were compared with dementia rates in participants with any other AHM. RESULTS: At baseline, 1951 participants (55.3%) used AHM [mean age, 74.4 year (SD 2.5); mean SBP, 156.4 mmHg (SD 21.5)]. In total, 986 participants (50.5%) used ß-blockers, 798 diuretics (40.9%), 623 angiotensin- converting enzyme inhibitors (31.9%), 522 CCBs (26.8%), and 402 ARBs (20.6%). After 6.7 years (interquartile range 6.0-7.3) of follow-up, 136 participants (7.0%) developed dementia. Both use of CCBs [hazard ratio 0.56, 95% confidence interval (95% CI) 0.36-0.87] and ARBs (hazard ratio 0.60, 95% CI 0.37-0.98) were independently associated with a decreased risk of dementia. The association of CCBs with dementia was most apparent in participants without a history of cardiovascular disease (hazard ratio 0.38, 95% CI 0.18-0.81) and with uncontrolled hypertension (hazard ratio 0.26, 95% CI 0.11-0.61). SBP was not significantly lower in participants using CCBs or ARBs. CONCLUSION: Both use of CCBs and ARBs are independently associated with a decreased risk of dementia in older people.

Perspectives of older people engaging in nurse-led cardiovascular prevention programmes: a qualitative study in primary care in the Netherlands.

BACKGROUND: Cardiovascular prevention programmes are increasingly being offered to older people. To achieve the proposed benefits, adherence is crucial. Understanding the reasons for adherence and non-adherence can improve preventive care. AIM: To gain insight into what motivates older people living in the community to partake in a cardiovascular prevention programme, and reasons for subsequent continuation or withdrawal. DESIGN AND SETTING: Qualitative study of current and former participants of the ongoing ≥6 year PreDIVA (prevention of dementia by intensive vascular care) trial in primary care practices in suburban areas in the Netherlands. METHOD: Semi-structured interviews were conducted with a purposive sample of 15 participants (aged 76-82 years). Interviews were audiorecorded and analysed by two independent researchers using a thematic approach. Participants were asked about their motivation for participating in the programme, along with the facilitators and barriers to continue doing so. RESULTS: Responders reported that regular check-ups offered a feeling of safety, control, or being looked after, and were an important motivator for participation. For successful continuation, a personal relationship with the nurse and a coaching approach were both essential; the lack of these, along with frequent changes of nursing staff, were considered to be barriers. Participants considered general preventive advice unnecessary or patronising, but practical support was appreciated. CONCLUSION: To successfully engage older people in long-term, preventive consultations, the approach of the healthcare provider is crucial. Key elements are to offer regular check-ups, use a coaching approach and to build a personal relationship with the patient.

Cardiovascular risk management in community-dwelling elderly: opportunities for prevention.

BACKGROUND: There is little information on the prevalence of hypertension and other modifiable cardiovascular risk factors in community-dwelling elderly in the Netherlands and the potential impact of improving antihypertensive treatment on major cardiovascular events. DESIGN: Cross-sectional analysis of Dutch community-dwelling subjects aged 70-78 years without dementia who were included in the cluster randomized preDIVA trial (Prevention of Dementia by Intensive Vascular care). METHODS: The prevalence of hypertension and other cardiovascular risk factors are described for participants with and without a history of cardiovascular disease (CVD). Projected benefits of blood pressure decrease are calculated using data from a meta-analysis and a large national registry. RESULTS: Of 3534 subjects, more than one-third (n = 1230, 35.2%) have a history of cardiovascular disease. Overall, 63% of subjects have two or more cardiovascular risk factors amenable to treatment. Systolic blood pressure (SBP) is ≥160 mmHg in 37% of patients with CVD, of which 28% is untreated. In subjects without a history of CVD, 41% have a SBP ≥ 160 mmHg of which 52% is untreated. A 5-15 mmHg decrease in SBP is projected to prevent 12-32% of coronary heart disease and 16-41% of strokes, respectively. This corresponds with 14-38 prevented cases within 2 years in our intervention group (n = 1895). CONCLUSIONS: Hypertension and other cardiovascular risk factors are very common in elderly subjects. Current (primary and secondary) prevention programmes appear insufficient. Improved antihypertensive treatment has the potential to prevent a substantial proportion of strokes and coronary heart disease in this population.

Association of vascular factors with apathy in community-dwelling elderly individuals.

CONTEXT: Apathy in community-dwelling elderly individuals has been associated with a history of stroke and other cardiovascular disease. OBJECTIVE: To assess the relationship between symptoms of apathy and cardiovascular risk factors or disease (stroke or other) in a large sample of elderly people aged 70 to 78 years without depression or dementia. DESIGN: Cross-sectional data analysis within an ongoing cluster-randomized, open, multicenter trial. SETTING: The Netherlands, general community. PARTICIPANTS: We studied 3534 elderly individuals without dementia who were included in the Prevention of Dementia by Intensive Vascular Care trial. MAIN OUTCOME MEASURES: Symptoms of apathy, assessed with 3 items from the 15-item Geriatric Depression Scale, in participants with few or no depressive symptoms. RESULTS: The median age of participants was 74.3 years. Principal components analysis of the Geriatric Depression Scale confirmed a separate factor for the apathy items (Geriatric Depression Scale-3A). Two or more symptoms of apathy were present in 699 participants (19.9%), of whom 372 (53.2%) were without depressive symptoms (Geriatric Depression Scale-12D score <2). Ordinal regression analysis showed that increasing apathy in the absence of depressive symptoms was associated with a history of stroke (odds ratio, 1.79; 95% CI, 1.38-2.31) and cardiovascular disease other than stroke (1.28; 1.09-1.52). Exploratory analysis among 1889 participants free from stroke and other cardiovascular disease revealed an association between apathy score and the following cardiovascular risk factors: systolic blood pressure (P = .03), body mass index (P = .002), type 2 diabetes mellitus (P = .07), and C-reactive protein (P < .001). CONCLUSIONS: Symptoms indicative of apathy are common in community-dwelling nondemented older people who are free from depression. The independent association of stroke, other cardiovascular disease, and cardiovascular risk factors with symptoms of apathy suggests a causal role of vascular factors.

Treatment of cardiovascular risk factors to prevent cognitive decline and dementia: a systematic review.

BACKGROUND: Over the last decade, evidence has accumulated that vascular risk factors increase the risk of Alzheimer disease (AD). So far, few randomized controlled trials have focused on lowering the vascular risk profile to prevent or postpone cognitive decline or dementia. OBJECTIVE: To systematically perform a review of randomized controlled trials (RCTs) evaluating drug treatment effects for cardiovascular risk factors on the incidence of dementia or cognitive decline. SELECTION CRITERIA: RCTs studying the effect of treating hypertension, dyslipidemia, hyperhomocysteinemia, obesity, or diabetes mellitus (DM) on cognitive decline or dementia, with a minimum follow-up of 1 year in elderly populations. OUTCOME MEASURE: Cognitive decline or incident dementia. MAIN RESULTS: In the identified studies, dementia was never the primary outcome. Statins (2 studies) and intensified control of type II DM (1 study) appear to have no effect on prevention of cognitive decline. Studies on treatment of obesity are lacking, and the results of lowering homocysteine (6 studies) are inconclusive. There is some evidence of a preventive effect of antihypertensive medication (6 studies), but results are inconsistent. CONCLUSION: The evidence of a preventive treatment effect aimed at vascular risk factors on cognitive decline and dementia in later life is scarce and mostly based on secondary outcome parameters. Several important sources of bias such as differential dropout may importantly affect interpretation of trial results.

Integrated dementia care in The Netherlands: a multiple case study of case management programmes.

The number of dementia patients is growing, and they require a variety of services, making integrated care essential for the ability to continue living in the community. Many healthcare systems in developed countries are exploring new approaches for delivering health and social care. The purpose of this study was to describe and analyse a new approach in extensive case management programmes concerned with long-term dementia care in The Netherlands. The focus is on the characteristics, and success and failure factors of these programmes.A multiple case study was conducted in eight regional dementia care provider networks in The Netherlands. Based on a literature study, a questionnaire was developed for the responsible managers and case managers of the eight case management programmes. During 16 semistructured face-to-face interviews with both respondent groups, a deeper insight into the dementia care programmes was provided. Project documentation for all the cases was studied. The eight programmes were developed independently to improve the quality and continuity of long-term dementia care. The programmes show overlap in terms of their vision, tasks of case managers, case management process and the participating partners in the local dementia care networks. Differences concern the targeted dementia patient groups as well as the background of the case managers and their position in the local dementia care provider network. Factors for success concern the expert knowledge of case managers, investment in a strong provider network and coherent conditions for effective inter-organizational cooperation to deliver integrated care. When explored, caregiver and patient satisfaction was high. Further research into the effects on client outcomes, service use and costs is recommended in order to further analyse the impact of this approach in long-term care. To facilitate implementation, with a focus on joint responsibilities of the involved care providers, policy recommendations are to develop incentives for collaborative financial contracts between insurers and providers.
