The QNI recognises that carers play a huge role in supporting people to live at home who otherwise would not be able to. It is in the interests of patients, carers, and healthcare professionals if nurses and carers work together as effectively as possible. With this in mind, the QNI has undertaken a project to identify the needs of carers in the community and how they may best be supported by District Nurses and their teams. As part of this work, a literature review was undertaken to explore and analyse the needs of carers. This paper presents the resulting evidence from a focused scoping exercise that builds a substantial body of knowledge to help District Nursing teams and other community nurses to develop a focussed approach towards carers’ needs. There are 5 strands to this work: 1. National key stakeholder engagement 2. Consultation with key stakeholders identified from the Queen’s Nurse network, including District Nurses, School Nurses and General Practice Nurses, 3. Resource development 4. Building on the resources previously developed as part of the carers' strategy which includes: o A review of current resources available to nurses; to identify gaps in resources available and test resources developed with carers’ and professional groups; o Production of learning materials to support early identification of carers’ needs and to provide appropriate sign posting; o Resource development that is fit for purpose to reach District Nursing teams, School Nurses, General Practice and other community nurses. 5. Education and training; o Review of current Nursing and Midwifery Council (NMC) ‘Standards for specialist education and practice’ (NMC 2001) to prepare specialist community practitioner nurses and make recommendations; o Champion and network development; o Link to the national District Nursing, Community Nurse and School Nurse Development programmes ; o Sharing innovation and dissemination of good practice of what works through collation of examples of good practice; o A literature review of current evidence of nurses providing support to carers. There are many reasons why adult and young carers have remained hidden and often unsupported when taking on levels of care that they have not been trained to provide. National UK health policy advocates and emphasises carer support in care throughout a patient’s illness and death (DH 2008a, DH 2008b, DH 2010a). The Government recognises the valuable contribution of carers who support the independence of other people; and they seek to empower this hidden group by supporting key national organisations such as Carers UK and Carers Trust (DH 2010a). However, contemporary Government papers emphasise the use of integrated care with strategic needs assessment and a strong personalisation agenda based on emerging evidence of effective early intervention in identifying, involving and supporting carers (DH 2010b, DH 2012, DH 2013a, DH 2013b). 2 Carers provide care because they want to help the people they care about and because their child, partner, relative or friend could not manage without that help. They often have to juggle the support and care they give with other responsibilities, in a difficult balancing act. For many carers, looking after their own health, combining caring with work, getting access to training or simply having time to take a break or go away for a weekend can be a major challenge. It is these aspects of carers’ needs that could be better supported and navigated with the assistance of the nurses and healthcare professionals that they come into contact with. The likelihood of any individual achieving this outcome will depend upon the provision of adequate support for those providing the bulk of home-focussed care (Plank, Mazzoni et al., 2012, Greenwood and Mackenzie 2010). The development of basic caring skills among informal caregivers is important. Patients’ and carers’ experiences of home-based care have been identified as a key factor in the appraisal of the quality of the professional care services they receive (O’Brien, Whitehead et al., 2012, Jack and O’Brien, 2010). Nevertheless, despite recognition of these experiences, previous studies have focussed predominantly on interventions and information provision for carers and patients and not necessarily on the professional needs of the health care practitioner engaged to support them (O’Brien, Whitehead et al., 2012, Jack and O’Brien, 2010, Plank, Mazzoni, et al., 2012, Greenwood and Mackenzie, 2010 ). Therefore, the practically-orientated support needs of informal carers, such as the skills required to provide physical care, will be highlighted through systematic attention in this literature review. Aims and objectives The aim of this study was to appraise the published evidence base relating to professionals and how they can support carers’ needs when providing care to patients in the community. For the purposes of this review community patients are people cared for in any environment that was not a hospital. The primary objectives of the literature review were to (i) explore the extent and origin of the literature relating to identifying and supporting carers by community nurses (with a specific focus on District Nursing, School Nursing and General Practice Nursing teams) within the community, (ii) identify the information and support needs of the professionals providing support to carers, (iii) identify potential strategies aimed at meeting carers’ needs to ensure the health and wellbeing needs of carers are identified early and appropriately with support to include sign posting and referral to avoid reaching crisis point and (iv) identify key areas of research where further work is needed to understand and improve the practical capabilities of these informal care providers by identifying a range of practice development resources and practical tools to support engagement activities within District Nursing teams, Community Nursing Services/School Nursing and General Practice Nursing in GP practices. This will improve joint work between primary care and other care settings (for example hospital services) to promote integration and an awareness of meeting the health and wellbeing needs of carers. Methods Design and search strategy: This study systematically reviewed available literature conducted via electronic searches of research and evidence-based databases via the knowledge platform at the Department of Health using the British Nursing Index (BNI) and the Cumulative Index to Nursing and Allied Health (CINHAL) Databases. All of the searches were conducted in May 2013. The search terms used in this review included the following key words; Health and wellbeing of carers Knowledge of local voluntary support for healthcare professionals Opportunities for healthcare professionals to engage with carers Issues that healthcare professionals believe are affecting carers 3 Healthcare professionals working with carers Working with carers Levels of understanding for carers Supporting carers Engaging with carers Identification of support needs for carers Sign posting carers to support Issues that are important to carers Issues that carers face The carer’s role Concerns for carers Issues for new carers Supporting carers in the local environment Support available for carers at a local level Awareness of the need to support carers Government policy in relation to carers Definition of a carer Information of support services for carers District nurses and carers Community nurses and carers Identification of carers’ needs Addressing carers’ health needs Addressing carer’s needs Good practice and carers in the community The initial search yielded six hundred and six records that were identified through the BNI and CINHAL databases using the stated key words. These records were then hand searched using abstracts and titles to ensure they were relevant to the research aims. Irrelevant or duplicate abstracts and titles were eliminated. Inclusion and Exclusion Criteria: Studies were eligible for inclusion in the review provided they reported primary research and presented data relating to professional support for carers. All study designs were acceptable for inclusion in the review including quasi-experimental studies, pre-post intervention designs (observational studies), descriptive studies and qualitative research studies. For the purposes of this review, care was taken to include all aspects of community care including nursing homes and hospices. Only English Language studies were included to avoid translation costs and any cultural misinterpretation. Limitations to dates were also applied, and only papers between 2006 and 2013 were included. Populations eligible for inclusion included any group responsible for the informal care of people in the community. This included any non-professional caregiver who provided care for an individual and for the purposes of this paper are referred to by a variety of terms including carer, home-based carer, informal carer, informal caregiver, etc. This reflects the inconsistency of the way these terms are used in the literature. Studies examining the carer’s experiences of hospital services were also excluded. Papers were also excluded if they reported descriptively on projects and programmes and had no robust evaluation component. The first review of the papers identified by the initial automatic trawl involved a hand search.Titles and abstracts from the publications were screened and papers were removed that were not 4 pertinent to carers needs in the community being supported by community nurses and health care professionals. This process resulted in one hundred and five records being identified as relevant. This data was then analysed and synthesised by comparing and contrasting individual study findings to identify prominent themes. This process produced a narrative synthesis around topics corresponding to the headings of Carers (generic), Mental Health and Carers , End of Life Care and Carers, Cardio-Vascular Disorders and Carers, Learning Disabilities and Carers, Neurological Disorders and Carers and Young Carers. A composite list of these findings grouped under the headings identified above can be found in APPENDIX ONE (n=71). No restriction was placed on study design and no specific quality criteria were used to identify studies eligible for inclusion. To identify threats to validity, key quality indicators were established. These were based on accepted guidelines for reviewing non-randomised, observational and qualitative literature and included at their core an assessment of each study’s response rate, sample selection process, representativeness and data validity (Khan, Riet, et al., 2001, CASP 2010). A standardised data extraction process was used to record the title, context, methodology and findings of each study. Two reviewers independently undertook all study eligibility judgements using the Critical Appraisal Skills Programme Tool (CASP 2010) with any disagreement being resolved through the involvement of a third party for arbitration. fHealth2011 Discussion This review has several limitations. The review was restricted to the BNI and CINHAL databases and limited to studies published in English. It therefore cannot be absolutely definite that other studies do not exist. The findings presented are tempered by the fact that many of the primary studies included in the synthesis suffered from their own methodological shortcomings. Despite the fact that the majority of eligible studies were from academic and published literature, most were local, single-site investigations involving largely non-representative samples with a potential for bias. Confidence in the internal validity of some of the findings is therefore limited and the generalisability of results unclear. However, it is possible, for example, that informal carers and professionals recruited from different geographical or healthcare localities may have expressed very different views to those included in the present synthesis. It is also noteworthy that many of the studies initially identified as being potentially relevant to this literature review were subsequently excluded due to weak methodologies as discussed above. Many of the studies being synthesised were local evaluations conducted across different countries for disparate readerships. The available research has, as this review shows, consistently reported that carers have requirements for practical nursing support and nursing-based information provision (Peeters, Van Beek, et al., 2010, Gort, Mingot, et al., 2007, Given, Sherwood, et al., 2008). However, despite being both understandable and logical, these requests often remain unfulfilled. The prominence of this theme across studies suggests that effective ways of delivering information and support to family caregivers needs to be developed and implemented to aid carers as a matter of priority (Gerrish, 2008, Couture, Ducharme, et al., 2012, Pinfold, Rapaport, et al., 2007). Current studies suggest that these interventions should include as a minimum, education and training related to emotional support and medication management. Flexible initiatives that are tailored to meet the needs of carers may ultimately confer the greatest benefits, both in terms of carers’ physical and emotional health and the well-being of their care recipients. Evidence assimilated within this review has clearly demonstrated that nurses and other health care providers could better assist home-based carers by providing the information and feedback necessary to undertake often basic practical nursing tasks. 5 Within the context of carers’ support requirements, this review did highlight a major gap in the literature around how professionals can best support carers. There is clear evidence that carers need support, guidance and signposting assistance, but there is no consideration in the literature of what education, training and skills staff may need to provide this support to carers. Further qualitative research is clearly indicated. However more recently the Government has charged the two organisations Skills for Health and Skills for Care with identifying some tool kits and resources for care activities and support (Skills for Health 2011). Skills for Health does have some basic toolkits available for staff and carers to support them. Key findings Some key studies identified that professionals acted on the assumption that family carers would, by choice or default, provide care (Bullard, 2007, Plank, Mazzoni, et al., 2012, Pattenden, Roberts, et al., 2007). Family carer support has also been conceptualized as a means of promoting self-care and reducing the patient’s dependence from nursing services (Gerrish, 2008). The rationale for providing family carer support appears to be based largely on service capacity rather than on carer needs and preferences (Gerrish, 2008, Sorrell, 2007, Taggart, Truesdale-Kennedy, et al., 2012, Tan, Williams, et al., 2012). Gerrish (2008) identified specific characteristics of District Nursing support for carers which include: enabling, supporting, mediating, care substitution, crisis prevention and crisis intervention. They purported that family carers were not recipients of District Nursing support in their own right but were dependent upon the cared-for person receiving nursing care. This in turn was conditional upon others (General Practitioners and hospital staff) making appropriate patient referrals. There is some indication from the studies examined that District Nurses and their teams need to take a more active stance in providing family carer support by adopting a family approach, rather than solely a patient focused approach in order that family carers might be supported more effectively (Bullard 2007, Plank, Mazzoni et al., 2012, Pattenden, Roberts, et al., 2007, Gerrish, 2008). The synthesised results of the seventy-one studies included in this literature review suggest that insufficient preparation and education of staff to support carers will have a substantial impact on Carer wellbeing (Carmichael and Hulme, 2008). Informal caregivers often experience the progressive and often long term nature of providing home-based care as both physically and mentally challenging (Lévesque, Ducharme, et al., 2010). In particular, carers who find it difficult to access support services report feelings of burnout and exhaustion (Bullard 2007, Freer, 2012). More generally, home caregivers frequently express considerable difficulties related to the feelings they experience caring for their loved ones, and significant difficulties dealing with emotional and technical problems relating to their caring duties. Without an adequate provision of information, families typically feel out of control, disempowered to make decisions and unable to cope with the physical care of a relative on a day to-day basis (Zwaanswijk, Van Beek, et al., 2010, O'Brien, Whitehead, et al., 2012). Multiple studies highlight that, in the absence of adequate support or guidance, many carers learn to cope with informal caregiving through a process of ‘trial and error’ with day-to-day tasks, assuming a significant emotional component, with the prospect of performing unfamiliar nursing tasks inducing stress in many carers (O'Brien, Whitehead, et al., 2012, Otis-Green and Juarez 2012, Freer, 2012 Carmichael and Hulme, 2008, Caress, Luker, et al., 2009). Adverse effects of incorrect caregiving have been identified as a key concern in carers’ evaluations of their nursing care abilities, and worries about these have been found in the context of general 6 patient care issues. Another common concern emanating from the literature is a lack of knowledge of medications (Caress, Luker, et al., 2009, O'Brien, Whitehead, et al., 2012, Hill, 2008). Health Professional Perspectives The limited number of studies that examined health professionals’ perspectives also acknowledged deficits in caregiver preparation, (Professional Perspectives table below - Page 10). District Nurses and community nurses typically viewed carers as ill-prepared both for the fundamental nursing care aspects and the exhaustive nature of the role (Jack, O’Brien 2010, Gerrish, 2008, Greenwood and Mackenzie, 2010 ). District Nurses and Community nurses also emphasise the psychological consequences of inadequate caregiver knowledge, which induces carer anxiety and impacts on caregiver confidence (Whitehead, O'Brien, et al., 2012, Walsh, Jones et al., 2007). 7 Health Professional Perspectives: AUTHOR (Gerrish 2008) DATE JOURNAL METHOD n TITLE/AIM/KEY OUTCOMES 2008 Primary Health Care Research and Development Ethnographic study.

This paper presents findings that examined how qualified district nurses’ conceptualized their role in relation to family carers and how they performed this aspect of their role. Family carer support was considered as a means of promoting self-care and the patient’s independence from nursing services. The rationale for providing family carer support was based largely on service capacity rather than on carer needs and preferences. Six characteristics of district nursing support for carers were identified: enabling, supporting, mediating, care substitution, crisis prevention and crisis intervention. Family carers were not recipients of district nursing support in their own right but were dependent upon the cared-for person receiving nursing care. As the scope of home-based nursing continues to increase, district nurses need to take a more active stance in providing family carer support and adopt a family rather than patient focused approach in order that family carers might be supported more effectively. “An exploratory study of Anxiety in Carers of Stroke Survivors” This study investigated anxiety in informal carers of stroke survivors. Background. Informal carers, also called caregivers, play a vital role in supporting stroke survivors. Emotional distress is also commonly reported but anxiety has received less attention than depression. Results indicated carers were more likely to have scores indicating anxiety than depression. Fourteen carers at one month and eleven at three months fell into both anxious and depressed categories.Concluding that anxiety is an important issue very early in caring whilst other research suggests it remains prevalent for many months. Given the significant role carers play in rehabilitation of stroke survivors, greater recognition of 8 their emotional state is required. Relevance to clinical practice. Nurses working in the community are ideally placed to identify and support carers suffering from anxiety.

Semistructured interviews using a grounded theory approach. n=11 frail older people "Home visits for frail older people: a qualitative study on the needs and preferences of frail older people and their informal caregivers.” This study explores the views and needs of community-dwelling frail older people concerning home visits. Most participants emphasised the importance of home visits for frail older people. They felt that it would give older people the personal attention they used to receive from GPs but miss nowadays. Most stated that this would give them more trust in GPs. Participants stated that trust is one of the most important factors in a good patient-professional relationship. Further, participants preferred home visits to focus on the psychosocial context of the patient. Patients' expectations of home visits are quite different from the actual purpose of home visiting programmes; that is, care and wellbeing versus cure and prevention. This difference may partly explain why the effectiveness of home visits remains controversial. British Journal of General Practice n= 11 informal caregivers 10 AUTHOR (Walsh, Jones, et al. 2007) DATE JOURNAL 2007 British Journal of Psychiatry METHOD Randomised Trial n 271 informal carers TITLE/AIM/KEY OUTCOMES Reducing emotional distress in people caring for patients receiving specialist palliative care To evaluate the effectiveness of increased support for distressed, informal carers of patients receiving palliative care. 271 informal carers who scored over 5 on the 28-item General Health Questionnaire (GHQ). The intervention comprised of 6 weekly visits by a trained advisor. Primary outcome was carer distress (GHQ-28) at week 4, 9 and 12 week follow up. Secondary outcomes were carer strain and quality of life, satisfaction with care, and bereavement outcome. Results – scores on the GHQ-28 fell below the threshold of 5/6 in a third of participants in each trial arm at any follow-up point. Mean scores in the intervention group were lower at all-time points but these differences were not significant. No difference was observed in secondary outcomes. Carers receiving the intervention reported qualitative benefit. The intervention might have been too brief, and on-going help might have been too brief, and on-going help might have had accruing benefits. Alternatively, informal carers of patients with cancer may already receive considerable input and the advisors help gave little additional advantage; or caring for a dying relative is extremely stressful and no amount of support is going to make it much better. (Whitehead, O’Brien, et al. 2012) 2012 Qualitative study: Narrative interviews with people with MND/ALS and family carers. n = 97 case reviews n = 24 people with MND/ALS n=18 family "Social services homecare for people with motor neurone disease/amyotrophic lateral sclerosis: why are such services used or refused?" This study aimed to identify factors related to uptake of homecare in MND/ALS. A case note review of patients at a UK MND/ALS clinic provided data concerning disease onset and severity, demographic variables and care received. Quantitative analyses highlighted the role of Palliat Med 11 carers increasing disease severity and age for social services homecare uptake. Findings revealed a number of barriers delaying the uptake of such care. 'Internal' issues focused on retaining control and normality within the home. 'External' issues arose from limited understanding of the disease amongst service providers and lack of awareness of service entitlement amongst patients and carers. Multiple factors are implicated in the uptake of social services homecare. Uncertainties surrounding service entitlement must be addressed, including the simplification of bureaucratic procedures and clarification of the roles of health and social care professionals. 12 A number of the publications discuss various aspects of the District Nurse and community nursing role, alongside an increase of faster throughput of hospital patients with an emphasis on caring for patients in their own homes (Jack, O’Brien, 2010, Whitehead, O’Brien, et al., 2012). The work undertaken by District Nurses and their teams in relation to complex nursing therapies, palliative/end of life care and the clinical support of highly dependent patients in home care settings has also dramatically increased (Jack, O’Brien, 2010). Some studies do highlight roles such as advocacy (Unwin, Le Mesurier, et al., 2008, Holdsworth and King, 2011) and fostering patient participation and carer involvement (Van Kempen, Robben, et al., 2012). Several papers report the perspectives of patients in receipt of care from District Nurses or community nurses and other health and social care agencies, but these focus primarily on the meeting of needs and experiences of care related matters rather than the carer role and the carer support requirement (Walsh, Jones, et al., 2007, O’Brien, Whitehead et al., 2012). In summary, there appears to be a lack of publications that robustly examine the differential roles of District Nurses and other community nursing services to ensure carers’ needs in the community are being supported adequately by District Nurses and community nursing teams. Conclusion In summary, existing publications portray the District Nursing and community nursing roles as difficult to define, overlapping in part with other services. Whilst it is acknowledged that there are more health/social care services in the community than can be discussed in a study of this length, the current traditional approach to District Nursing and community nursing service provision appears to focus insufficiently on how these professionals can appropriately assist informal carers. Historically, carers’ needs were a high priority for the District Nurse (NMC 2001). However, District Nursing as a profession is currently subject to a significant decline in the number of qualified District Nurses and in investment in recruitment and training (QNI 2013). Yet despite this enormous professional erosion, District Nursing services face a huge extension in service delivery expectation which is inconsistent with the national breadth of demand. Whilst much of the national design of community nursing service provision and community nursing roles appears to be dependent on geography or local make up of District Nursing and/or community nursing teams, with a reduced qualified District Nursing workforce, there is now a distinct gap in service and a lack of leadership and knowledge about the needs of carers and how carers’ can be appropriately supported to avoid carer breakdown. The topic of carer identification, information and support within community nursing services appears to be under-researched. It is, perhaps, time for a major review of the models to support carers supporting nursing and personal care needs of patients’. This could involve a better understanding of the tools and resources District Nursing teams and community nurses working in Primary Care need to successfully engage with carers’ and support them in this unique and challenging role. 13 References : Bullard, R.
