Federated health data becomes the NHS’s strongest defence against winter demand

By Sanius Health

The NHS is shifting focus towards preventative care ahead of what officials expect will be one of the most challenging winters in recent years.

The health service hopes that better use of data can help it identify risk earlier, manage capacity more effectively and save billions of pounds in avoidable costs.

More than a decade of rising demand has left hospitals operating near capacity throughout the year.

In winter, those pressures intensify as respiratory illness, falls and chronic disease flare-ups increase admissions. Emergency departments become crowded, ambulance waits lengthen and thousands of routine procedures are postponed.

With the November strikes from doctors across the country, rising demand for beds and the NHS facing one of its most constrained financial periods in decades, leaders are being forced to rethink how the system prepares for pressure rather than simply reacts to it.

NHS England believes part of the solution lies not in more beds or staff, but in foresight.

Under the leadership of Ming Tang, its Chief Data and Analytics Officer, the organisation is using the Federated Data Platform (FDP) to anticipate where pressure will emerge and act before services reach breaking point.

The team at NHSE has said that the aim is to move from reacting to problems to preventing them, by giving local teams access to live data on patients most at risk of deterioration.

Predicting Demand Before It Happens

The FDP connects existing systems used by hospitals, GP practices, community teams and local authorities, creating a single shared view of local populations.

The technology allows staff to see which patients are likely to require additional support such as home oxygen, vaccination or social care visits before they arrive in hospital.

By analysing clinical data alongside factors such as housing, weather and previous hospital use, the platform can flag people who may be vulnerable to cold weather or infection.

Community teams can then intervene earlier, helping patients remain at home safely.

According to NHS England, regions testing the approach have reported reductions in emergency admissions of up to 10 per cent, along with improvements in discharge planning and patient flow.

Officials believe that if scaled nationally, the system could save between £8 billion and £10 billion a year through avoided admissions and shorter hospital stays.

A Broader Shift in Strategy

The move reflects a wider policy change inside the health service.

For decades, most NHS spending has gone on treating illness rather than preventing it.

Preventative care such as screening, vaccination, chronic disease management and social support has often been the first area to face cuts when budgets tighten.

Yet evidence suggests the economics favour prevention.

The NHS Confederation has estimated that each £1 spent on prevention can return up to £14 in reduced treatment costs. Analysts argue that better management of cardiovascular disease, diabetes and respiratory illness alone could remove billions from annual hospital budgets.

Connecting those efforts through shared data could make them far more effective.

“When you can see risk across the system, you can act before it becomes pressure,” a member of the NHSE team said. “That is what the platform is designed to enable.”

Preparing for a Difficult Winter

Hospital leaders are already warning of significant strain this winter.

Industrial action, high bed occupancy and delayed discharges are expected to coincide with a rise in influenza and Covid-19.

Officials say using predictive models to target early intervention could help ease demand on acute services and support staff in managing capacity.

Integrated Care Systems in regions such as Greater Manchester, Humber and North Yorkshire have begun using the FDP to monitor high-risk groups and coordinate care across community and hospital settings.

The approach allows resources to be deployed dynamically, whether opening step-down capacity, scheduling home visits or prioritising elective procedures.

NHS England describes the platform as an information layer rather than a new database, linking existing systems rather than replacing them.

Each organisation retains control of its own data while benefiting from a common operational view.

From Data to Decisions

What “federated data” means in practice is that each organisation retains control of its own information while contributing to a shared, secure view of the system.

Data is not centralised or removed from local systems, but connected through common standards so that hospitals, councils and community teams can see the same picture in real time

Officials stress that technology alone will not resolve the pressures. The impact will depend on how effectively data is turned into action.

The intention is that insights generated by the FDP support local decision-making, helping clinical and operational teams respond faster and plan with greater confidence.

If successful, the initiative could mark a turning point in how the NHS manages its busiest season.

Prevention, supported by live data and shared accountability, may not remove winter pressures entirely, but it could make them predictable, manageable and less costly.

For a service long defined by its ability to respond, that would represent a quiet but profound change.
