This is a plain English summary of an original research article

There are four broad areas to consider when implementing a school-based health promotion programmes: preparing for implementation, introducing a programme within a school, embedding a programme into routine practice, and fidelity of implementation and programme adaptation. This review identified specific factors for success for each. This was based on 22 studies (some of them NIHR-funded) around health promotion interventions in UK schools. Common factors that improved the chances of successful implementation included engaging pupils, teachers and senior staff, explaining the value of the intervention in relevant terms, having a specific co-ordinator to support staff and enabling staff to discuss and resolve implementation issues. A wide range of health promotion programmes were considered, including healthy eating, smoking, alcohol consumption and accidental injuries.

The findings give pragmatic evidence-based advice on how best to implement school-based programmes. This has potential to minimise money being wasted because of the poor implementation of programmes known to work. It will be particularly helpful for school nurses and others.

Why was this study needed?

The risk of developing many common diseases in the UK can be lowered by making lifestyle changes. For example, reducing salt intake to reduce the risk of heart disease or maintaining a healthy weight to reduce the risk of diabetes.

Many suggest that promoting healthy lifestyle choices – health promotion – should start early in life to help establish healthy habits early and prevent disease, rather than trying to reverse unhealthy habits later in life, or once illness had occurred. As such, school is recognised by NICE as an important setting for improving various aspects of health promotion, such as preventing excess weight gain, improving oral health and reducing smoking and alcohol use.

This review investigated the factors that contributed to successful or unsuccessful implementation of UK school-based health promotion programmes.

What did this study do?

This was a “realist” review – meaning it focused on the implementation of interventions, rather than their effectiveness. The first part of the review used 22 UK-based studies (some funded by NIHR) to produce a framework of the different aspects of implementation, known as “programme theories”. These programme theories were then tested and refined using a further 41 studies. Data were extracted until “theoretical saturation”, the point at which adding new studies is considered unlikely to yield further insight. Studies were also critically appraised so that the authors could indicate the quality of the evidence underlying their findings.

What did it find?

  • The review identified four “programme theories” affecting implementation success: preparing for implementation, introducing a programme within a school, embedding a programme into routine practice, and fidelity of implementation (how closely the reality matched the intention) and programme adaptation.
  • Preparing. Integration was more likely to be successful when systematically planned in line with the school’s existing responsibilities. This involved pre-delivery consultation. New or contentious programmes may need more consultation than well-established or uncontentious programmes. Pupils need to understand the relevance and benefits, and teachers and pupils need to feel supported. The authors identified the notion of reciprocity, with both teachers and pupils needing clear benefits (including non-health advantages, such as developing transferable skills) to participate. The new programme should be fitted in with current school activities.
  • Introducing. Successful implementation was more likely if health promotion programmes are integrated into the life of the school. This can be achieved through appropriate senior level support, a named co-ordinator showing leadership, and positive engagement with teachers, public and others involved in the programme delivery or participation.
  • Embedding. There was limited evidence informing how to best embed a programme into routine practice.
  • Implementing. Limited evidence also informed best approaches to ensure fidelity – i.e. how closely the programme stuck to the original aims. But elements to consider were around programme adaptation, and the elements of the programme that are essential, optional and adaptable by those delivering it.

What does current guidance say on this issue?

NICE guidelines relating to health promotion programmes in schools cover: alcohol interventions (PH7), physical activity for children and young people (PH17), smoking prevention in schools (PH23) and social and emotional wellbeing in primary education (PH12) and secondary education (PH20). Where implementation advice is provided, it reflects the findings of this review. For example, using a “whole school” approach to embed programmes into the school, family and wider community – such as in the case of oral health programmes (2014), smoking prevention (2010) and alcohol consumption (2007).

What are the implications?

The focus in research can often – and understandably – be on the effectiveness of an intervention, rather than how it can be best implemented in different contexts. Both are important for success. This review suggests implementation issues to consider when selecting and planning the implementation of health promotion programmes in schools. For instance, it may be helpful to identify which parts of a programme are standard and which could be adapted to fit the needs of local schools. The “programme theories” developed in this review should be considered by those implementing programmes to maximise the chance of successful implementation and minimise the possibility of wasting resources through poor and non-evidence-based implementation.
