Integrated care boards (ICBs) across England have been given three years to begin implementing outcome-based contracts, marking a significant shift in how NHS services are commissioned and delivered. The requirement forms part of new national guidance published in early 2026, which outlines the next phase of NHS reform centred on population health and value-based care. Under the plan, ICBs must demonstrate tangible progress towards adopting contracts that prioritise patient outcomes over activity levels within this timeframe.

This represents a major departure from traditional NHS contracting models, which have historically focused on volume and activity-based payments. The reforms are closely linked to the government’s long-term ambition for integrated care systems to operate as strategic commissioners, shifting responsibility for delivering care and managing resources to provider-led organisations.

Integrated health organisations at the core of reform

At the centre of the new approach is the introduction of integrated health organisation (IHO) contracts, a model that gives providers responsibility for delivering care to a defined population under a single budget. Under this structure, ICBs will commission a lead provider, typically a large NHS trust or partnership, to act as the IHO, overseeing care delivery across multiple services and organisations. The IHO will then subcontract services to other providers, including community, primary care and specialist organisations, creating a more coordinated system of care.

These contracts are designed to incentivise providers to focus on prevention, early intervention and community-based services, rather than hospital activity. By linking funding to outcomes, the model aims to encourage more efficient use of resources and better health results for patients. NHS England has indicated that IHO contracts are expected to become the dominant commissioning model by the mid-2030s, with the next three years acting as a critical transition period.

2026–27 to serve as ‘developmental year’

The 2026–27 financial year will act as a “developmental” phase for the new contracting approach, with NHS England working closely with early adopters to refine the model before wider rollout. During this period, ICBs and providers will test new payment mechanisms, develop outcome measures and build the infrastructure required to support population-based commissioning.

A “shadow” set of outcome metrics is also being developed, drawing on the NHS Outcomes Framework and international best practice, to help standardise how performance is measured. This phased approach reflects the complexity of moving to outcome-based contracts, which require significant changes to financial flows, data systems and organisational culture. The first wave of IHO contracts is expected to be awarded from 2027, following a period of co-design between NHS England, ICBs and selected provider organisations.

Digital infrastructure critical to success

From a health technology perspective, the transition to outcome-based contracting will depend heavily on robust digital infrastructure and advanced data capabilities. Unlike traditional contracts, which can be measured through activity metrics such as hospital admissions or procedures, outcome-based models require detailed insights into patient health outcomes, population needs and service performance.

This will necessitate the widespread use of data analytics platforms, interoperable electronic patient records and population health management tools. These systems will enable ICBs and providers to track outcomes in real time, identify high-risk groups and adjust services accordingly.

The reforms also place greater emphasis on data sharing across organisations, as providers will need access to comprehensive patient information to deliver coordinated care. In addition, digital tools such as predictive analytics and AI could play a growing role in identifying patterns, forecasting demand and supporting preventative interventions. However, the success of these technologies will depend on addressing existing challenges around interoperability, data quality and workforce capability.

Challenges around implementation and accountability

While the move towards outcome-based contracts is widely seen as a positive step, it presents several significant challenges. One of the key issues is defining and measuring outcomes in a consistent and meaningful way. Health outcomes can be influenced by a wide range of factors, including social determinants, making it difficult to attribute results to specific interventions.

There are also concerns about risk transfer, as providers taking on IHO contracts will assume greater responsibility for managing budgets and delivering outcomes across entire populations. Ensuring that smaller providers and voluntary sector organisations are not marginalised within this model will be another important consideration. From a governance perspective, ICBs will retain their role as strategic commissioners, responsible for setting outcomes, monitoring performance and ensuring accountability across the system.

A fundamental shift in NHS commissioning

The introduction of outcome-based contracts represents one of the most significant changes to NHS commissioning in recent years. By moving away from activity-based funding towards a model focused on value and outcomes, policymakers aim to create a more sustainable and patient-centred health system.

For the health technology sector, the reforms signal growing demand for digital solutions that can support data-driven decision-making, performance monitoring and integrated care delivery. As ICBs begin the transition over the next three years, the focus will be on building the capabilities needed to deliver this new approach, both in terms of technology and organisational readiness.

A critical period for system transformation

The three-year timeline sets a clear expectation for progress, but also allows flexibility for local adaptation and learning. Success will depend on effective collaboration between commissioners, providers and technology partners, as well as sustained investment in digital infrastructure and workforce development.

Ultimately, the shift to outcome-based contracting is intended to align financial incentives with patient outcomes, supporting a more integrated and preventative model of care. As the NHS moves through this transition, the coming years will be critical in determining whether these ambitions can be realised in practice, and whether the system can deliver better outcomes for patients while maintaining financial sustainability.
