BackgroundPolice mental health street triage is an increasingly common intervention when dealing with police incidents in which there is a suspected mental health component. We conducted a systematic review of street triage interventions with three aims. First, to identify papers reporting on models of co-response police mental health street triage. Second, to identify the characteristics of service users who come in to contact with these triage services. Third, to evaluate the effectiveness of co-response triage services.MethodsWe conducted a systematic review. We searched the following databases: Ovid MEDLINE, Embase, PsycINFO, EBSCO CINAHL, Scopus, Thompson Reuters Web of Science Core Collection, The Cochrane Library, ProQuest National Criminal Justice Reference Service Abstracts, ProQuest Dissertations & Theses, EThoS, and OpenGrey. We searched reference and citation lists. We also searched for other grey literature through Google, screening the first 100 PDFs of each of our search terms. We performed a narrative synthesis of our results.ResultsOur search identified 11,553 studies. After screening, 26 were eligible. Over two-thirds (69%) had been published within the last 3 years. We did not identify any randomised control trials. Results indicated that street triage might reduce the number of people taken to a place of safety under S136 of the Mental Health Act where that power exists, or reduce the use of police custody in other jurisdictions.ConclusionsThere remains a lack of evidence to evaluate the effectiveness of street triage and the characteristics, experience, and outcomes of service users. There is also wide variation in the implementation of the co-response model, with differences in hours of operation, staffing, and incident response.Electronic supplementary materialThe online version of this article (10.1186/s12888-018-1836-2) contains supplementary material, which is available to authorized users.

BackgroundPsychosocial person-centred interventions are considered best practice for addressing complex behaviours and care needs such as agitation and anxiety, and for improving the quality of life of people with dementia in care homes. Dementia Care Mapping (DCM™) is an established practice development tool and process aimed to help care home staff deliver more person-centred care. To date, few studies have evaluated the efficacy of DCM™ and have found mixed results. These results are suggested to be the outcome of intervention implementation, which may be impacted by a range of factors. This study reports the barriers and facilitators to DCM™ implementation in care homes found during the process evaluation conducted as part of a randomized controlled trial.MethodsEighteen of the 31 DCM™ intervention care homes were recruited to participate in the embedded process evaluation. Semi-structured interviews were conducted with 83 participants, comprising care home managers, trained DCM™ users (mappers), expert external mappers, staff members, relatives, and residents.ResultsBarriers and facilitators to DCM™ implementation were found at the mapper level (e.g. motivation and confidence), the DCM™ intervention level (e.g. understanding of DCM™) and the care home level (e.g. staffing issues, manager support). Further barriers caused by the burden of trial participation were also identified (e.g. additional paperwork).ConclusionsImplementing DCM™ is complex and a greater consideration of potential barriers and facilitators in planning future studies and in practice could help improve implementation.Trial registrationCurrent Controlled Trials ISRCTN82288852, registered 16/01/2014.

Background The quality of care for people with dementia in care homes is of concern. Interventions that can improve care outcomes are required. Objective To investigate the clinical effectiveness and cost-effectiveness of Dementia Care Mapping™ (DCM) for reducing agitation and improving care outcomes for people living with dementia in care homes, versus usual care. Design A pragmatic, cluster randomised controlled trial with an open-cohort design, follow-up at 6 and 16 months, integrated cost-effectiveness analysis and process evaluation. Clusters were not blinded to allocation. The primary end point was completed by staff proxy and independent assessors. Setting Stratified randomisation of 50 care homes to the intervention and control groups on a 3 : 2 ratio by type, size, staff exposure to dementia training and recruiting hub. Participants Fifty care homes were randomised (intervention, n = 31; control, n = 19), with 726 residents recruited at baseline and a further 261 recruited after 16 months. Care homes were eligible if they recruited a minimum of 10 residents, were not subject to improvement notices, had not used DCM in the previous 18 months and were not participating in conflicting research. Residents were eligible if they lived there permanently, had a formal diagnosis of dementia or a score of 4+ on the Functional Assessment Staging Test of Alzheimer’s Disease, were proficient in English and were not terminally ill or permanently cared for in bed. All homes were audited on the delivery of dementia and person-centred care awareness training. Those not reaching a minimum standard were provided training ahead of randomisation. Eighteen homes took part in the process evaluation. Intervention Two staff members from each intervention home were trained to use DCM and were asked to carry out three DCM cycles; the first was supported by an external expert. Main outcome measures The primary outcome was agitation (Cohen-Mansfield Agitation Inventory), measured at 16 months. Secondary outcomes included resident behaviours and quality of life. Results There were 675 residents in the final analysis (intervention, n = 388; control, n = 287). There was no evidence of a difference in agitation levels between the treatment arms. The adjusted mean difference in Cohen-Mansfield Agitation Inventory score was –2.11 points, being lower in the intervention group than in the control (95% confidence interval –4.66 to 0.44; p = 0.104; adjusted intracluster correlation coefficient: control = 0, intervention = 0.001). The sensitivity analyses results supported the primary analysis. No differences were detected in any of the secondary outcomes. The health economic analyses indicated that DCM was not cost-effective. Intervention adherence was problematic; only 26% of homes completed more than their first DCM cycle. Impacts, barriers to and facilitators of DCM implementation were identified. Limitations The primary completion of resident outcomes was by staff proxy, owing to self-report difficulties for residents with advanced dementia. Clusters were not blinded to allocation, although supportive analyses suggested that any reporting bias was not clinically important. Conclusions There was no benefit of DCM over control for any outcomes. The implementation of DCM by care home staff was suboptimal compared with the protocol in the majority of homes. Future work Alternative models of DCM implementation should be considered that do not rely solely on leadership by care home staff. Trial registration Current Controlled Trials ISRCTN82288852.

One-third of people with dementia live in care home settings and in order to deliver better evidence-based care, robust research including clinical trials is required. Concerns have been raised by researchers about the capacity of care home residents with dementia to participate in clinical trials. This includes self-report measures, completion of which researchers have suggested may be unreliable or impossible and may cause distress for residents. Many trials, therefore, utilise only proxy completed outcome measures. This is despite evidence that individuals with mild through to advanced dementia can reliably report on outcomes, if appropriate measures and approaches to data collection are used. However, little has been written about best practice in data collection with this group. This study aimed to explore the experiences of researchers working on dementia trials in care homes and identify best practices to assist design of future trials. Thirty-three researchers completed an online, qualitative questionnaire outlining their experiences and the perceived benefits and challenges of data collection with people with dementia. We identified five main benefits: (1) improving the delivery of person-centred care, (2) hearing the voice of people with dementia, (3) residents spending time with researchers, (4) improving researcher understanding, and (5) having an evidence base from multiple sources. We also identified five main challenges: (1) effective communication, (2) fluctuating capacity, (3) causing distress to residents, (4) time pressures, and (5) staff availability. Researchers also made suggestions about how these can be overcome. We recommend that the challenges identified could be overcome using appropriate methods for collecting data. Thorough training for researchers on data collection with people with dementia was identified as important for ensuring successful data collection.

Aims and methodStreet triage services are increasingly common and part of standard responses to mental health crises in the community, but little is understood about them. We conducted a national survey of mental health trusts to gather detailed information regarding street triage services alongside a survey of Thames Valley police officers to ascertain their views and experiences. RESULTS: Triage services are available in most areas of the country and are growing in scope. There is wide variation in levels of funding and modes of operation, including hours covered. Police officers from our survey overwhelmingly support such services and would like to see them expanded.Clinical implicationsMental health crises now form a core part of policing and there are compelling reasons for the support of specialist services. Recent changes to the law have heightened this need, with a requirement for specialist input before a Section 136 is enacted. Those who have experienced triage services report it as less stigmatising and traumatic than a traditional approach, but there remains little evidence on which to base decisions.Declaration of interestNone.

Objectives: Agitation is common and problematic in care home residents with dementia. This study investigated the (cost)effectiveness of Dementia Care Mapping TM (DCM) for reducing agitation in this population. Method: Pragmatic, cluster randomised controlled trial with cost-effectiveness analysis in 50 care homes, follow-up at 6 and 16 months and stratified randomisation to intervention (n ¼ 31) and control (n ¼ 19). Residents with dementia were recruited at baseline (n ¼ 726) and 16 months (n ¼ 261). Clusters were not blinded to allocation. Three DCM cycles were scheduled, delivered by two trained staff per home. Cycle one was supported by an external DCM expert. Agitation (Cohen-Mansfield Agitation Inventory (CMAI)) at 16 months was the primary outcome. Results: DCM was not superior to control on any outcomes (cross-sectional sample n ¼ 675: 287 control, 388 intervention). The adjusted mean CMAI score difference was-2.11 points (95% CI-4.66 to 0.44, p ¼ 0.104, adjusted ICC control ¼ 0, intervention 0.001). Sensitivity analyses supported the primary analysis. Incremental cost per unit improvement in CMAI and QALYs (intervention vs control) on closed-cohort baseline recruited sample (n ¼ 726, 418 intervention, 308 control) was £289 and £60,627 respectively. Loss to follow-up at 16 months in the original cohort was 312/ 726 (43Á0%) mainly (87Á2%) due to deaths. Intervention dose was low with only a quarter of homes completing more than one DCM cycle. Conclusion: No benefits of DCM were evidenced. Low intervention dose indicates standard care homes may be insufficiently resourced to implement DCM. Alternative models of implementation, or other approaches to reducing agitation should be considered.

Background: Many people with dementia live in care homes, where staff can struggle to meet their complex needs. Successful practice improvement interventions in these settings require strong managerial support, but little is known about how managers can support implementation in practice, or what factors support or hinder care home managers in providing this support. Using Dementia Care Mapping™ (DCM) as an example, this study explored how care home managers can support the implementation of complex interventions, and identified factors affecting their ability to provide this support. Methods: We undertook interviews with 48 staff members (managers and intervention leads) from care homes participating in the intervention arm of the DCM EPIC trial of DCM implementation. Results: Managerial support played a key role in facilitating the implementation of a complex intervention in care home settings. Managers could provide practical and financial support in many forms. However, managerial support and leadership approaches towards implementation were highly variable in practice, and implementation was easily de-stabilised by management changes or competing managerial priorities. How well managers understood, valued and engaged with the intervention, alongside the leadership style they adopted to support implementation, were key influences on implementation success. Conclusions: For care home managers to effectively support interventions they must fully understand the proposed intervention and its potential value. This is especially important during times of managerial or practice changes, when managers lack the skills required to effectively support implementation, or when the intervention is complex. It may be unfeasible to successfully implement new interventions during times of managerial or practice instability.

Aims and methodStreet triage services are now common but the population they serve is poorly understood. We aimed to evaluate a local service to determine the characteristics of those using it and their outcomes in the 90 day period following contact.ResultsWe found that there were high levels of service use and that the vast majority of contacts were via telephone rather than in person. Street triage was used by both existing secondary mental health patients and non-patients. Follow-up rates with secondary services were high in the former and low in the latter case.ImplicationsServices are very busy where they exist and may be replacing traditional crisis services. It is not apparent that they work to increase follow-up among those using them, unless they are already in contact with services. In this service, although there was a joint response model nearly all responses were provided by telephone.
