The need for an intersectoral approach in health policy
Improving population health is the main goal of health policies, and yet health is influenced by more than just health policies. It follows that a ‘health in all policies’ approach is needed. This means that different sectors, such as environmental or housing, consider the health implications of their policies and work together to improve population health.
At the individual level, it means recognising that a person’s health is influenced by multiple factors – the social determinants of health – and solutions need to target these root causes, and the interplay between them, to have a real impact.

What drives policy change?
Easy answer? It depends. Multiple models exist, but perhaps the most compelling conceptual framework is the Kingdon Streams Model, which identifies three causes of policy change: problem, policy and politics.
‘Problem’ can mean that a new issue comes to the political agenda, for example because of pressure from advocacy groups or a shift in epidemiology (e.g. a pandemic). ‘Policy’ is about a shift in process, for example a shuffling of government departments. ‘Politics’ is about political will and convergence of interests within government towards the need for change.
The confluence of these three streams creates a window of opportunity for policy change. And the key factor is time – these changes may happen concurrently, or at different times, but somehow a tipping point occurs and a change in policy is proposed.
The Kingdon Streams Model assumes a fairly rational process, though there are many who suggest that the only stream that really matters is the politics stream, and that policy change is more chaos than process.
I take a less cynical view: I strongly believe in the ability of evidence to drive policy change, and the power of advocacy to change ideas governing policy. Invariably, the most powerful driver of policy change is people – not only those with the ability to change policy, but also those who can influence it by challenging the governing values and interests and communicating a compelling, evidence-based case for change.
Who can effect change in policy?
Civic society has a strong role to play in shaping policy – think back to the role of ACT UP in shaping HIV/AIDS policy in the 1980s and 1990s. But policy change can also be strongly influenced by healthcare professionals, the general public and the private sector.
The ideal scenario is that all ‘advocates’ come together to join forces, creating a case for change that takes account of all perspectives and unmet needs. A powerful example of this is the WHO Framework Convention on Tobacco Control, which set in motion a global movement of anti-tobacco policies that have had significant impact in many countries around the world. Similarly, global policies on antimicrobial resistance (AMR) recognise that change on the ground will require collaboration between the WHO, public health, the scientific community, healthcare professionals, pharmacovigilance and the life science industry.
