Summary
This chapter covers particular aspects of knowledge and skills that enable you to draw on evidence, undertake research and use various techniques to inform and prioritise your health promotion work. These include linking your work into broader national and local health promotion plans and strategies, basing your work on evidence of effectiveness, using published research, doing your own small-scale research, getting value for money, audit and health impact assessment.
The role of the NHS and local government in planning health strategies is outlined in Chapter 4. How local policy is made and implemented is discussed in Chapter 16.
International (such as the World Health Organization (WHO) 2006) and national health strategies focus efforts on agreed priorities, and provide the framework for setting objectives and monitoring progress towards their achievement. A health promoter at a local level contributes to these broader strategies and complements work of other health promoters. Fig. 7.1 illustrates how health promoters from different local agencies complement each other’s efforts in contributing to national goals of increasing physical activity in the population.

National Public Health Strategies
The first national health improvement strategy in England was The Health of the Nation (Department of Health (DoH) 1992). There were comparable strategies for Wales, Scotland and Northern Ireland.
See also Chapter 1, section on national initiatives.
The National Audit Office (1996) reporting on The Health of the Nation targets concluded that, while the initiative was making an impact, progress was uneven and slow. Deaths from heart disease, strokes and certain cancers were being reduced but there were rising levels of obesity, alcohol consumption by women and smoking by children which threatened to undermine health gains.
In the areas where targets were being reached, it was difficult to determine how far this was due to health promotion efforts (Appleby 1997). For example, there was a decrease in the rate of accidental deaths (many due to road accidents) in children. But this could have been because of improved education about accident prevention or a safer environment, such as more traffic calming schemes. Or it could have been because more injured children were saved from dying with better or quicker treatment, or maybe even because parents were informed of the risks of letting their children out to play, walk to school or cycle on the roads, so that their exposure to life-threatening risks was reduced.
A final assessment of The Health of the Nation (DoH 1998) concluded that, although the strategy was widely welcomed, it did not realise its full potential and was not seen to be as important as other health service priorities, such as waiting lists. Some key findings were that the strategy made little impact on local policy making, caused only a slight increase in health promotion spending, did not impact on primary care practitioners or hospital services, and was generally disliked by local authorities because of its disease-led targets. On the positive side, the evaluation indicated that the strategy enabled coordinated health promotion efforts, providing a focus for organisations outside the NHS to be involved and a spur to multiagency action where previous joint work had not existed.
The report made useful recommendations for the success of future health promotion strategies, calling for more evidence-based practice and evaluation and performance management.
New national strategies were introduced in the late 1990s and then again in the 21st century:
• England: Saving Lives: Our Healthier Nation (DoH 1999) and Choosing Health: Making Healthy Choices Easier (DoH 2004). The key principle of Choosing Health: Making Healthy Choices Easier is to support the public in making healthier and more informed choices in regards to their health. The Government pledged to provide information and practical support to get people motivated and improve emotional wellbeing and access to services so that healthy choices are easier to make.
• Northern Ireland: Health and Wellbeing: Into the Next Millennium (Department of Health and Social Services (DHSS) 1997), Investing for Health (Department of Health, Social Services and Public Safety 2002). Investing for Health presents a cross-departmental, multisectoral framework for action to improve health and wellbeing. The strategy recognises the important contribution to be made by members of statutory and nonstatutory groups, community and voluntary groups. The principles and values that should guide the improvement of health are identified and the costs of poor health are highlighted. The aims are to address a broad range of economic, social and environmental determinants of health and wellbeing.
• Scotland: Towards a Healthier Scotland (Scottish Office (SO) 1999). Better Health, Better Care: Action Plan (SO 2007). Better Health, Better Care has central themes of patient participation, improved healthcare access, and improving health and tackling health inequalities. This action plan sets out to help people to take more control of their health, especially in disadvantaged communities, ensuring better, local and faster access to health care. The three main components of health improvement, tackling health inequality and improving the quality of health care are set within a comprehensive programme of targeted action.
• Wales: Promoting Health and Wellbeing: Implementing the National Health Promotion Strategy (National Assembly for Wales (NAW) 2001a) and the associated Improving Health in Wales: a Plan for the NHS and it’s Partners (NAW 2001b). Promoting Health and Wellbeing: Implementing the National Health Promotion Strategy sets out key elements of helping communities through local health alliances, health promoting schools, community health development, reaching young adults and developing a healthy workforce. There are targeted programmes covering a wide range of public health action. Other elements of the plan cover improving the skills and knowledge of health promoters, better communication of health information, health impact assessment, and research and evaluation.
Health promoters need to take account of these strategies and their emphasis on individual responsibility for health, the need to address the wider determinants and the importance of partnership working.
See Chapter 1, section on national initiatives, for more about inequalities targets.
Local Health Strategies and Initiatives
There are many government-initiated local health programmes that provide sources of funding for health promotion. Local strategies were given new impetus with the development of health improvement programmes, later known as health improvement and modernisation plans (HIMPs). These required more coordination between local agencies at both a strategic and operational level than had previously been the case. HIMPs for action were based on local needs that cover prevention and health promotion as well as treatment and care services. They emphasised reducing inequalities and developing partnerships to address locally identified needs and national health strategy priorities. To explore the impact they had on health promotion see Abbott & Gillam (2001).
See also Chapter 4 for the role of the health service and local government in promoting health.
Others local strategies include the following.
Local strategic partnerships
At a local level the NHS is involved in local strategic partnerships (LSPs), has oversight of the community plan (see below) and in areas of deprivation is responsible for developing a local strategy for neighbourhood renewal (see http://www.neighbourhood.gov.uk for links to local websites for LSPs and http://www.idea.gov.uk for information on local area agreements and LSPs).
Community strategies
Local authorities have powers to promote or improve local economic, social and environmental wellbeing. They are required to prepare community strategies (or plans) and to coordinate these activities (see Darlow et al 2008) and associated partnerships across a wide range of agencies (see, for example, LutonForum 2005).
Neighbourhood renewal strategy
The Neighbourhood Renewal Strategy and Fund was launched in 2001 (Social Exclusion Unit 2001) and set out a joined-up approach to tackling the social and economic determinants of health in the most deprived local authority areas.
Healthy living centres
The Healthy Living Centres (HLCs) Initiative was launched in 1999, funded from the National Lottery to develop a network of HLCs across the UK. This funding is usually used for programmes of activity rather than a physical building. For examples of the work of HLCs see Rankin et al (2006) and for an evaluation of the whole scheme see Hills et al (2005). HLCs are not mentioned in recent policy, but the intention at the outset was that HLCs would become sustainable and there is evidence that this is happening (see, for example, Chesterfield Borough Council 2009).
Health action zones
The first wave of health action zones (HAZs) was set up in 1997 with special government funding to improve health outcomes and reduce health inequalities (Health Development Agency 2004). HAZs have pioneered new ways of tackling health inequalities through partnership working between the NHS, local authorities, community groups, the voluntary and private sectors; linking health, regeneration, education, housing and anti-poverty initiatives. A central aim for HAZs was integrating the services and approaches they develop into mainstream activity, and some made considerable progress and had an impact on local health improvement (Barnes et al 2005, Bauld and MacKenzie 2007). Where HAZs still exist they have been incorporated into mainstream agencies, for example, Northern Neighbourhoods Health Action Zone (http://www.nnhaz.co.uk).
The New Deal for Communities (NDC)
The NDC programme involved funding to poorest neighbourhoods in the country for 10 years to support plans that bring together local people, community and voluntary organisations, public agencies and local business in an attempt to make lasting improvements to health, employment, education and the physical environment. It was the intention that these improvements would be delivered in a way that could be sustained beyond government funding and into the long term. The government has issued various guidance notes which relate to succession, but Healey (2009) argues that it is too early to make an assessment of the contribution that guidance and shared good practice from the NDC programme is making to the development of local sustainability plans in NDC areas. For an example of how NDCs function see Newcastle New Deal for Communities (http://www.newcastlendc.co.uk).
Sure Start
This is a government scheme which aims to support parents and children under 4 years in areas of high health need (see Gidley 2007 for a more detailed discussion of the Sure Start programme and http://www.dcsf.gov.uk for publications relating to recent Sure Start funding and other initiatives).
Exercise 7.1 aims to help you find out about national and local health strategies relevant to your work.
EXERCISE 7.1
1. Have a look at the national strategy for health in your country (see section on National Health Strategies above to find out about yours). Try the Internet, libraries at educational institutions or at work, colleagues in health promotion or planning at your place of work, or contact the public health department of your local NHS organisation.
2. What do you think are the good and not-so-good points about your national strategy?
3. How does your own health promotion work contribute to the aims set out in the national strategy?
4. If you work in the NHS or local authority, list your local health plans and strategies and assess:
▪ What are the good and not-so-good points about your local plans?
▪ How do the local plans relate to your national strategy?
▪ How does your own health promotion work contribute to the aims set out in your local plans?
Evidence-Based Health Promotion
Delivering evidence-based health promotion is a key goal within the international, national and local strategies outlined above (Jones & Scriven 2005, Scriven 2008) Health promoters are required to know how to assess the evidence and apply the assessment to practice.
This requires competencies in:
• Critically appraising primary and secondary research.
• Knowledge of the hierarchy of evidence.
• Assessment of evidence of effectiveness of services, programmes and interventions, which impact on health.
• Conducting a literature review, which includes the use of electronic databases, defining a search strategy and summarizing results.
• Applying research evidence, evidence of effectiveness, outcome measures, evaluation and audit to influence health promotion programme interventions, services or development of practice guidelines.
• Interpreting and balancing evidence of effectiveness from a range of sources to inform decision making.
See Chapter 2 for more information on competencies in health promotion.
An evidence-based approach provides a defense against the indiscriminate use of practices in situations which have no research-based legitimacy. Evidence-based health promotion requires a culture where you openly share your experience and write up and publish your work, which enables others to learn from your successes and failures. It uses the skills of reflective practice, thinking about what you do and questioning whether it is the right approach in your situation.
How Do You Know What Works?
There can be a gap between evidence and practice. It is not always easy for practitioners to keep up-to-date with new research findings, or to apply research findings in their own particular situation. Attention needs to be given to how research findings can best influence and also emerge from practice, and the processes of disseminating and implementing health promotion research.
There are many published research studies that help to show which health promotion interventions work best. These are easily accessible on the Internet at such sites as Cochrane (http://www.cochrane.org); the International Union of Health Promotion and Health Education (IUHPE) data source (http://www.hp-source.net) and the main evidence-based Internet site for health promotion in England, the National Institute for Health and Clinical Evidence (NICE) (http://www.nice.org.uk).
Health promotion is complex and it is sometimes difficult to provide evidence of effectiveness for single interventions. Often it is not one intervention that produces results, but a combination of activities, of which you may be involved in just one, as Fig. 7.1 demonstrates. Another example is preventing childhood obesity, where the evidence is that a multifaceted approach is the most effective. A combination of interventions range from targeting antenatal education, to working with parents and ensuring they have access to buying affordable healthy foods, to increasing children’s physical activity levels, through the targets set by the Schools Sports Strategy (OFSTED 2006) and ensuring healthy food consumption while children are at school using the new standards, which cover all food sold or served in schools (Department for Children, Schools and Families 2005).
Research shows that for many health promotion issues a more comprehensive, integrated approach that focuses both on attitudes and behaviours and changes to such things as the environment and legislative and fiscal policies is the most effective (see, for example, National Audit Office et al 2006).
Evidence may also not exist. The particular piece of work you plan to undertake may not have been done before, and indeed the particular set of circumstances in which you are working may be unique. So the best that can be done is to be aware of what the published research in related areas of work tells you, and to reflect on how what was learned might apply to your circumstances. Where evidence is not available, it is vital to ensure that you evaluate your work in order to add to the evidence base by drawing the evidence from your practice and disseminating the results.
It also helps to think carefully about what constitutes evidence (for a useful discussion on these issues see Kelly et al 2004). Evidence can be drawn informally, with the views of local people and your own experience also constituting evidence. Your job as a health promoter is to use your judgement to decide whether the evidence available applies to your clients and circumstances and, if so, how. GPs, for example, may quote a number of factors which they believe provide evidence that health promotion is effective, including changes in the health or health behaviour of their patients over time.
However, formal sources of evidence are generally regarded as the most reliable, so you should plan carefully and evaluate or audit what you do. In this way you will be building up your own body of knowledge about what is effective.
Audit is discussed later in this chapter.
Finally, it is also important to bear in mind that your decision about whether to do a particular piece of health promotion work should also be based on ethical considerations. You could decide that it is your responsibility to intervene, even though you have little or no information about what might work. Health promotion is driven by both values and evidence, which are often intertwined. So there are two key questions: Do we think this ought to be done? and Will it work?
See Chapter 3 for more about values and ethics in health promotion.
Using Published Research
Health promoters need to be well informed about published research and also how to use their knowledge of research findings to improve their practice. Familiarity with research findings can also give you arguments on which to base a case for more, or different and better, health promotion. Keeping abreast of current evidence should be part of your everyday working practice.
How to Search the Literature
You may sometimes wish to find out about research on a particular topic, perhaps because you are proposing to introduce new health promotion work and want to know what has been shown to work best. For example, imagine you are a nurse working in cancer care and you are considering introducing a counselling service for women who are undergoing mastectomy (surgery to remove a breast, usually because of breast cancer). You want to know if research shows what the health promotion needs of these women are and how best to meet them. Where do you start?
First you need to establish a research question. It pays to take time to discuss this with colleagues and you could also discuss it with someone who has recently had a mastectomy. What did she find helpful, and what was unhelpful?
Once you are clear about what you want to find out, list no more than six key words that feature in your question. The cancer care nurse might include the words mastectomy, needs and counselling in her list. Then write words that mean the same thing, or are similar in meaning, by each key word. For example, you might put breast removal as an alternative to mastectomy, and advice as an alternative to counselling. These key words and their synonyms/alternatives will be helpful when you go to the library or search on the Internet (for excellent guides to doing your literature search and finding information online, see Aveyard (2007) and Dochartaigh (2007)). In addition, many journal articles include a list of key words after the title, which will help you to know whether the article is likely to be of interest to you. When you have found a few references, you can start by reading the most recent one. This will provide you with more references. Once you are under way, the next problem is to avoid being swamped by information. Here again, your key words should be useful in stopping you from being side-tracked and in keeping your research question in mind.
It is important to keep records of what you read. There is computer software designed to help you store and retrieve references (see for a comparison of the different software http://en.wikipedia.org). For a book, you need to record:
• author’s (or editor’s) surname and initials
• year published
• title and subtitle
• edition, if not the first
• chapter, or numbers of pages, if you are only going to refer to part of the book
• place of publication
• publisher.
For articles in journals you need to record:
• author’s surname and initials
