Collaboration drives equity: the power of cross-cutting policy
19 October 2026
How can working across sectors help tackle the root causes of health inequalities?
Equitable health outcomes do not begin and end in hospitals, clinics or doctors’ surgeries. They are shaped every day by where we live, learn, work and travel, and by the opportunities available to us. Policies on housing, transport, education, employment, the environment and taxation all influence our health.
That’s why improving health and reducing inequalities requires coordinated action beyond the health sector. A cross-cutting approach recognises this; it brings people, expertise and organisations together to tackle interconnected challenges and better meet people’s needs.
As health systems come under increasing pressure, this kind of collaboration is no longer optional. It is essential if we are to make better decisions, use resources more effectively and address the root causes of ill health.
Why integrated policy matters for health equity
Public institutions often work in silos, making it harder to tackle complex social challenges and inequalities that cut across sectors – and the consequences of this are both human and financial. Health inequalities lead to poorer outcomes, reduced participation in society and increased pressure on health systems. The European Parliament has estimated that losses linked to health inequities cost around 1.4% of gross domestic product in the European Union.

Against this backdrop, there is growing recognition that fairer, healthier societies depend on different sectors working together. Cross-cutting policy helps policymakers align priorities, maximise impact and deliver shared benefits for people, communities and economies.
Collaboration however remains challenging because organisations are often accountable to their own priorities, goals and governance structures, rather than shared outcomes. Differences in organisational cultures, competing objectives, fragmented funding arrangements and a lack of shared data systems can all make collaboration difficult.
Health in All Policies: a framework for collaboration
One of the most established cross-cutting strategies is the World Health Organization (WHO) initiative Health in All Policies (HiAP). It recognises that health is shaped not only by healthcare services but also by decisions across government, and aims to ensure that all sectors consider their impact on health and health equity.
HiAP encourages policymakers to look beyond the priorities of a single department and consider how decisions affect different population groups. Transport policy, for example, can influence air quality, access to employment and physical activity. Housing policy can affect safety, financial security and exposure to environmental risks. And education and employment policies can shape opportunities throughout the life course.
By making these wider impacts visible, HiAP supports decision-making, helping sectors identify shared goals, manage trade-offs, avoid unintended harms and work together to improve health and equity.
However, collaboration does not happen automatically. It requires strong leadership, clear governance, shared accountability, and adequate resources and expertise. Tools such as health impact assessments help ensure health is considered when decisions are made, but their use is inconsistent. Such tools would benefit from clearer guidance, sustainable funding and stronger integration into routine policymaking.
At its core, cross-cutting policy is about ensuring public services work for the people they serve.
Cross-cutting policy in practice
The value of cross-cutting policy in reducing inequities can be seen in many areas, particularly where people’s exposure to health risks and ability to access prevention and care are shaped by decisions beyond the health sector.
- Oncology: Inequalities in cancer outcomes are influenced by factors including access to education, prevention, research, social support and technology. Cross-cutting approaches help ensure that opportunities to achieve better outcomes reach people from different communities. Examples include California’s Cancer Prevention Act, which promotes HPV vaccination awareness in schools, and the National Cancer Policy Forum, which addresses issues spanning prevention, treatment and health inequalities.
- Digital health: Coordination in healthcare, technology, regulation, finance and workforce planning helps ensure that digital systems are accessible and work for people with different needs and circumstances. Estonia’s e-health system illustrates the need to align data infrastructure, privacy, digital identity and healthcare delivery, while the WHO’s Global Strategy on Digital Health highlights the importance of governance, interoperability, equity and workforce capacity.
- Cardiovascular health: Cardiovascular risk is closely linked to the environments in which people live, work and access food, education and transport, meaning opportunities for good cardiovascular health are not equally distributed. Coordinated action in these sectors helps create healthier environments at a population level and reduce avoidable inequalities. The CARDIO4Cities initiative unites partners from different sectors to address cardiovascular risk factors. In São Paulo, Dakar and Ulaanbaatar, the initiative improved population-level hypertension control up to sixfold within two years, contributing to reductions of up to 12% in strokes and 13% in heart attacks.
These examples demonstrate that to reduce health inequalities, cross-cutting policy requires practical mechanisms for collaboration, including shared objectives, joint accountability, integrated funding and common data systems. They also highlight that health is a political choice. To build government support, health leaders must understand the priorities of other sectors and show how improving health contributes to wider social, economic and environmental goals.
Health equity must be the priority
At its core, cross-cutting policy is about ensuring public services work for the people they serve. Embedding equity into policymaking means considering not only whether a policy improves overall outcomes, but also who benefits, who may be left behind, and how avoidable differences between groups can be reduced.
Cross-cutting policy is not a silver bullet, but it offers a practical way to address inequalities in health outcomes and make better use of limited resources. By working towards shared goals, sectors can tackle the root causes of poor health, reduce inequalities and create healthier, fairer societies.
