On the High Street, competition law creates a competitive market by ensuring a range of different suppliers, fostering competition based on price, avoiding monopolies and probing vertical integration in the supply chain (for example, supermarkets owning dairies).
But there are other models for preserving the consumer interest which recognise that certain areas of our national life have specific characteristics that require a different approach.
Last month, for example, saw a highly publicised row between two train operating companies bidding for a long term, monopoly, franchise. The franchise deliberately runs for long enough to enable the operator to earn a sufficient return on the expensive infrastructure needed to provide a quality customer service.
Last month also saw the closure of the football transfer window, which restricts the times when clubs can buy new players. Clubs also now have to abide by new Financial Fair Play rules which are designed to create a level playing field by restricting the amount of money wealthy owners can invest to "buy success".
What does all this have to do with the NHS? The Health and Social Care Act, passed earlier this year, marks the next stage in the journey away from a single, all encompassing, command and control health service. It continues work begun by the previous Labour administration to create a more plural system where, in some areas of care, a wider range of providers compete to provide services for patients. As a result, patients have greater choice rather than, for example, being forced to use the closest NHS hospital.
But the health sector is not the High Street. Competition is based on quality, not price, with the price of an increasing range of treatments determined by a single tariff, to be set in future by a central Commissioning Board and the sector regulator. There also needs to be a strong emphasis on integrating care, defined by the NHS Future Forum as "integration around the patient, not the system". The Forum went on to argue that "outcomes, incentives and system rules (i.e. competition and choice) need to be aligned accordingly".
It's easy to see why integrating care is so important. An 80 year old frail patient with multiple problems needs a joined-up network of acute and primary care services where geriatricians, nurses, physiotherapists, and podiatrists all understand the individual patient's needs, and the care provided has no gaps - an integrated care pathway.
Diabetic patients in Bolton now have a centre staffed by specialists that care for inpatients at the local hospital but also care for patients at home by working with GPs. The very GPs who, in future, are likely to have commissioned the centre to provide this service. Elderly patients in several Surrey care homes are visited by hospital based geriatricians who advise staff and help to prevent patients being admitted to hospital unnecessarily.
These are all examples of good, joined-up, care: benefitting individual patients, reducing cost and providing better value for money for the taxpayer. But they do involve integration across the NHS, between different organisations that may be commissioning or competing with each other to provide services. Some might argue this reduces competition.
The Foundation Trust Network, which represents the vast majority of acute, mental health, community and ambulance providers in the NHS, is co-hosting fringe sessions at all the party conferences to explore how the NHS can achieve the right balance between integration and competition. It's an important question as the detailed rules for the new NHS are finalised over the next six months.
We'll also be particularly focussed on the importance of the NHS sustaining a flourishing and vibrant set of public providers over the longer term. The way the new rules are formulated will have a crucial impact here. If we get them wrong, there's a danger, to focus on another cause celebre in the competition world, that these organisations could turn into the dairy farmers of the healthcare sector. They might end up working for payments that do not cover costs; forced to sign up to short term contracts that offer no incentive to invest in innovations that improve quality and efficiency and facing an uncertain financial future.
