Health inequalities are differences in health across the population and between different groups in society that are systematic, unfair and avoidable. They are caused by the conditions in which people are born, live, work and grow. These conditions influence peoples' opportunities for good mental and physical health.1
Reducing health inequalities is one of NICE's core principles. NICE's guidance supports strategies that improve population health as a whole while offering particular benefits to the most disadvantaged. Adopting NICE's recommendations into practice will ensure the care provided is effective and consistent and makes efficient use of resources. And ultimately, it reduces the impact of health inequalities on people's health.2
Generally, a form called Equality and Health Inequalities Assessment (EHIA) is created when developing each guidance topic. EHIA records the approaches used to identify potential equality and health inequalities issues, identifies inequalities issues and how these were considered and addressed at each stage of the guideline development process. However, the EHIA is largely based on the input from the developers and topic experts as well as the health inequalities raised by committee members. Further information on our process and methods can be found in our guidelines manual.3
NICE is exploring new approaches to addressing health inequalities in guidance development. One approach used, and the focus of this brief research report, is the development of the overarching health inequalities briefing to inform health inequality issues on any breast cancer-related topic update.
The health inequalities briefing for breast cancer was a pragmatic, targeted review of evidence exploring the health inequalities associated with breast cancer. It aimed to support both the NICE development team and the committee during breast cancer guidance development to consider health inequalities issues more systematically and transparently. The findings within the briefing also highlighted key gaps in evidence, potential research questions and research recommendations not only to NICE but to the wider health and care system from a health inequalities perspective.
A small technical team was formed to develop a briefing protocol, conduct searches, review and summarise research, interpret findings and undertake independent quality assurance. In the health inequalities briefing, the King's Fund framework (Table 1) for health inequalities was used to synthesise examples of the key health inequalities faced by populations in England across the four dimensions of inequality and five levels of outcomes for each dimension.
To be pragmatic, the initial search focused on real-world evidence, including routinely available data sources, such as national cancer registry datasets and key published reports on inequalities by charities, nongovernm
