Abstract
BACKGROUND Urinary tract infection (UTI) is the most diagnosed infection in older people living in care homes. OBJECTIVE To identify interventions for recognising and preventing UTI in older people living in care homes in the UK and explain the mechanisms by which they work, for whom and under what circumstances. METHODS A realist synthesis of evidence was undertaken to develop programme theory underlying strategies to recognise and prevent UTI. A generic topic-based search of bibliographic databases was completed with further purposive searches to test and refine the programme theory in consultation with stakeholders. RESULTS 56 articles were included in the review. Nine context-mechanism-outcome configurations were developed and arranged across three theory areas: (1) Strategies to support accurate recognition of UTI, (2) care strategies for residents to prevent UTI and (3) making best practice happen. Our programme theory explains how care staff can be enabled to recognise and prevent UTI when this is incorporated into care routines and activities that meet the fundamental care needs and preferences of residents. This is facilitated through active and visible leadership by care home managers and education that is contextualised to the work and role of care staff. CONCLUSIONS Care home staff have a vital role in preventing and recognising UTI in care home residents.Incorporating this into the fundamental care they provide can help them to adopt a proactive approach to preventing infection and avoiding unnecessary antibiotic use. This requires a context of care with a culture of personalisation and safety, promoted by commissioners, regulators and providers, where leadership and resources are committed to support preventative action by knowledgeable care staff.

Abstract
Background Care homes are complex settings to undertake intervention research. Barriers to research implementation processes can threaten studies’ validity, reducing the value to residents, staff, researchers and funders. We aimed to (i) identify and categorise contextual factors that may mediate outcomes of complex intervention studies in care homes and (ii) provide recommendations to minimise the risk of expensive research implementation failures. Methods We conducted a systematic review using a framework synthesis approach viewed through a complex adaptive systems lens. We searched: MEDLINE, Embase, CINAHL, ASSIA databases and grey literature. We sought process evaluations of care home complex interventions published in English. Narrative data were indexed under 28 context domains. We performed an inductive thematic analysis across the context domains. Results We included 33 process evaluations conducted in high-income countries, published between 2005 and 2019. Framework synthesis identified barriers to implementation that were more common at the task and organisational level. Inductive thematic analysis identified (i) avoiding procedural drift and (ii) participatory action and learning as key priorities for research teams. Research team recommendations include advice for protocol design and care home engagement. Care home team recommendations focus on internal resources and team dynamics. Collaborative recommendations apply to care homes’ individual context and the importance of maintaining positive working relationships. Discussion Researchers planning and undertaking research with care homes need a sensitive appreciation of the complex care home context. Study implementation is most effective where an intervention is co-produced, with agreed purpose and adequate resources to incorporate within existing routines and care practices.

Abstract
OBJECTIVES Agitation is common and problematic in care home residents with dementia. This study investigated the (cost)effectiveness of Dementia Care Mapping™ (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 = 31) and control (n = 19). Residents with dementia were recruited at baseline (n = 726) and 16 months (n = 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 = 675: 287 control, 388 intervention). The adjusted mean CMAI score difference was -2.11 points (95% CI -4.66 to 0.44, p = 0.104, adjusted ICC control = 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 = 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 (43·0%) mainly (87·2%) 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.

Facilitators and barriers to implement nurse-led interventions in long-term dementia care: a qualitative interview study with Swiss nursing experts and managers. BMC Geriatr 2021; 21:159. [PMID: 33663417 PMCID: PMC7932832 DOI: 10.1186/s12877-021-02120-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2020] [Accepted: 02/22/2021] [Indexed: 11/30/2022] Open
Abstract
Background To support the implementation of nurse-led interventions in long-term dementia care, in-depth knowledge of specific supporting factors and barriers is required. Conditions and structures of caring for people with dementia differ widely, depending on the country and the care context. Our study aimed to describe the experiences and opinions of nursing experts and managers with regard to facilitators and barriers to the implementation of nurse-led interventions in long-term dementia care. Methods We conducted a qualitative descriptive study using individual interviews based on qualitative vignettes as a useful stimulus to generate narrations allowing to study peoples’ perceptions and beliefs. The study took place in nursing homes in the German-speaking part of Switzerland and in the Principality of Liechtenstein using purposive sampling. We intended to conduct the interviews face-to-face in a quiet room according to the participant’s choice. However, due to the lockdown of nursing homes during the COVID-19 pandemic in spring 2020, we performed interviews face-to-face and by video. We analysed data thematically following Braun and Clarke to achieve a detailed, nuanced description. To verify our interpretation and to ensure congruence with participants’ perspectives, we conducted member checks. The Standards for Reporting Qualitative Research (SRQR) served to structure our manuscript. Results Six dyads of nursing home managers and nursing experts from six nursing homes took part in our study (n = 12). Our thematic analysis yielded seven themes reflecting facilitators and barriers to implementing nurse-led interventions in long-term dementia care: «A common attitude and cohesion within the organization», «Commitment on several levels», «A needs-oriented implementation», «The effect and the public perception of the intervention», «A structured and guided implementation process», «Supporting knowledge and competencies», as well as «Resources for implementing the intervention». Conclusions To support the implementation of nurse-led interventions in long-term dementia care, active commitment-building seems essential. It is necessary that the value of the intervention is perceptible.Commitment-building is the precondition to reach the persons involved, such as nursing home managers, nursing staff, residents and relatives. Furthermore, nurses should precisely inform about the intervention. It is necessary that the value of the intervention is perceptible. In addition, nurses should adjust the interventions to the situational needs of people with dementia, thus. Therefore, it is important to support dementia-specific competencies in long-term care. Findings indicate that the barrier is determined by the intervention and its implementation – and not by the behaviour of the person with dementia.

Staff experiences of implementing Dementia Care Mapping to improve the quality of dementia care in care homes: a qualitative process evaluation. BMC Health Serv Res 2021; 21:138.

Abstract
BACKGROUND Dementia Care Mapping™ (DCM) is a widely used, staff-led, psychosocial intervention to support the implementation of person-centred care. Efficacy evaluations in care homes have produced mixed outcomes, with implementation problems identified. Understanding the experiences of staff trained to lead DCM implementation is crucial to understanding implementation challenges, yet this has rarely been formally explored. This study aimed to examine the experiences of care home staff trained to lead DCM implementation, within a large cluster randomised controlled trial. METHODS Process evaluation including, semi-structured interviews with 27 trained mappers from 16 intervention allocated care homes. Data were analysed using template variant of thematic analysis. RESULTS Three main themes were identified 1) Preparedness to lead - While mappers overwhelmingly enjoyed DCM training, many did not have the personal attributes required to lead practice change and felt DCM training did not adequately equip them to implement it in practice. For many their expectations of the mapper role at recruitment contrasted with the reality once they began to attempt implementation; 2) Transferring knowledge into practice - Due to the complex nature of DCM, developing mastery required regular practice of DCM skills, which was difficult to achieve within available time and resources. Gaining engagement of and transferring learning to the wider staff team was challenging, with benefits of DCM largely limited to the mappers themselves, rather than realised at a care home level; and 3) Sustaining DCM - This required a perception of DCM as beneficial, allocation of adequate resources and support for the process which was often not able to be provided, for the mapper role to fit with the staff member's usual duties and for DCM to fit with the home's ethos and future plans for care. CONCLUSIONS Many care homes may not have staff with the requisite skills to lead practice change using DCM, or the requisite staffing, resources or leadership support required for sustainable implementation. Adaptations to the DCM tool, process and training may be required to reduce its complexity and burden and increase chances of implementation success. Alternatively, models of implementation not reliant on care home staff may be required.

Abstract
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.

Abstract
Background Targeting perinatal depressive symptoms among women can reduce premature mortality. However, public health professionals (PHPs) in primary healthcare settings often have low self-efficacy for detection and management of perinatal depressive symptoms among women. This mixed-methods study was aimed at developing and evaluating a self-efficacy improvement programme (SIP) intended to increase PHPs’ self-efficacy in efforts to detect and manage perinatal depressive symptoms. Methods The SIP consisted of 1 day of theory and 4 weeks of practice. Sixty-six PHPs from sub-district health promotion hospitals (primary health care level) in Sakonnakhon, a north-eastern province in Thailand, were randomised into an intervention group (n = 33) and a control group (n = 33). Twenty-three of the intervention group participants also took part in focus group discussions (FGDs). Multiple linear regression and qualitative content analysis were used to analyse the data. Results After the SIP, the intervention group participants had higher self-efficacy score than those in the control group (p = 0.004). The FGDs resulted in four categories emerging: Having confidence, Changing knowledge and attitudes, Increasing perception of an important role, and Increasing awareness of performed function. Conclusions To enhance the ability of PHPs to detect and manage perinatal depressive symptoms, an intervention programme based on self-efficacy modification is recommended.
