What is driving the 'left shift' in medicine?

25 July 2024

It’s no secret the NHS is struggling with waiting lists - more than 1 in 10 people in the country was on the NHS waiting list[1] for hospital treatment in September last year. It’s an issue that has many causes, and one that those in the industry have been working hard to resolve. Everyone – from local health workers to consultants and surgeons – understands that these aren’t just numbers, these are people.

The answer to the problem for many in the healthcare sector is not just about investing in bricks and mortar hospitals or training news doctors and nurses (though these are important) – it’s also about going back to the source. About making sure that the stream of people joining the back of the queue is reduced.

This left shift in thinking – from the end of the queue to the start of the queue - is driving a change in how we view healthcare and how we tackle issues with the NHS. It involves focusing our efforts on boosting primary care services and access to healthcare earlier, to help alleviate the stress on acute care.

Markus Bolton Executive Director said:

A left shift - by treating more patients in primary care or in the community, and reducing referrals and treating in secondary care - makes perfect sense.

It is often more effective, reduces pressure on hospitals and costs less. However, identifying the right people to receive that care is a crucial part of the puzzle.

Referral to treatment statistics

The most recent NHS data[2] shows that the referral to treatment (RTT) waiting times continue to grow. In April 2024, there was 7.6 million people waiting to start treatment. Some patients are on multiple pathways, but even so, there are still 6.3 million unique patients waiting.

·           Over 300,000 have been waiting for over a year

·           Over 50,000 were waiting more than 65 weeks

·           More than 5,000 cases have been waiting for more than 78 weeks

·           58.3% of cases have been waiting up to 18 weeks – well below the 92% target

·           In April 2024, 1.7m new RTT pathways were started

·           Just 310,000 pathways were completed as a result of admitted treatment

·           1.17m were completed in other ways (non-admitted)

These statistics highlight the pressing need to stop the stream of people starting new pathways. With around 220,000 people added to the list in April 2024 alone, it’s not sustainable for the NHS. 

Why the left shift in medicine

The left shift refers to a shift in the focus from the end of the waitlist to why people join the waiting list.

Instead of trying to treat hundreds of thousands of more people within the secondary and acute care system, the aim is to reduce the number of people joining the waiting list by focusing on primary care.

This works by providing earlier treatment. If you can treat people earlier, then in many cases their conditions don’t escalate, and they don’t require in-patient, hospital care.

Neal Batra, MBA, a principal in Deloitte’s life science and health care practice was quoted in Medical Economics as saying: “Our perspective is that there is a handful of mechanisms that are available in the market that allow us to now move from a reactive sick-care model to one that can be much more proactive with faster reaction, that will let us either anticipate illness or address it much earlier and allow us to get back to health faster.”

What is driving the shift

While the growing waiting list has been the main driver for the switch in focus, another driver has been identified. Covid impacted everyone’s life – and its impact was felt most in the healthcare system.

While it piled the pressure on an already damaged healthcare system, it also required new kinds of thinking in terms of how, when and where we treat people.

Hospitals were becoming full and unsafe with the rise of Covid – so people were being encouraged to use other methods to contact and liaise with healthcare professionals.

The techniques introduced during Covid that moved people from hospital care to primary care included[3]:

·           Digital triage

·           Remote consultation

·           Coordinated discharges

·           Admission avoidance techniques

·           Sharing of waiting lists

·           Rapid technology deployment

·           Patient-initiated follow-up

·           Digital advice and guidance

·           ‘Call before you walk’ scheme

Some of these techniques have continued to be used in a bid to help claw back some capacity within the NHS.

What impact could the left shift have on the NHS?

The left shift and a focus on primary care could help the NHS in a number of ways.

·         Lower rates of serious conditions: Conditions like cancer, diabetes and others that can require acute care if not caught early could be tackled in a more effective manner if they spotted at primary care levels. Many of these could even be treated as outpatients, reducing the need for in patient care and beds.

·         Reduction of emergency admissions: NHS England reports[4] areas with better access to primary care services have seen lower growth in emergency hospital admissions. This suggests that when primary care is accessible, patients are less likely to wait until their conditions worsen to seek help, reducing the strain on emergency services.

·         Less pressure on acute care: The reduction in emergency admissions and catching serious conditions earlier could lead to reduction in pressure on acute care units.

·         Reduction in waiting lists: This all would, in turn, reduce the waiting lists, freeing up doctors’ and specialists’ resources to spend more time with patients and treating those who are acute cases.

·         Beds freed up: Eventually, the beds would be freed up meaning those in need of beds could get one and stay in one for longer periods, allowing longer recovery times and reducing the risk of readmittance.

One downside of this would be that it adds more pressure on primary care providers. GPs, mental health services, social services and in community elderly care providers are already under huge pressure.

The shift left doesn’t simply mean putting more people into the primary care system, but providing ways to make this more efficient and effective.

The impact of the shift left on patients

While the impact on the NHS is important, we also need to bear in mind the impact this shift would have on people.

A study published in the International Journal for Equity in Health[5] showed that improved access to primary care, particularly in socioeconomically disadvantaged areas, led to better management of chronic conditions like Type 2 diabetes.

By providing better funding and more efficient primary care system in the UK, we would make it easier to access GPs, mental health care and social workers. Even if people aren’t using these services, knowing they have easy and readily available access would be a huge benefit.

·         Easier access to local GPs and primary care: With investment and a more effective primary care service, it would mean people would have easier access to these services.

·         Higher engagement with healthcare services: Surveys and patient feedback indicate that ease of access to primary care, such as being able to book appointments conveniently, is linked with higher patient satisfaction and better engagement with healthcare services. This improved engagement leads to more timely medical interventions and better overall health.[6]

·         Better management of conditions: Community pharmacies have been instrumental in flu vaccinations and managing conditions like asthma, which helps in early intervention and better health management overall​.[7]

·         Rise in self-care: People with conditions that need management would be in a better position to manage that condition themselves – whether that’s better management of medicines or having a bigger say in when and where they receive treatment. [8]

·         More likely to catch serious illness and receive treatment earlier: For more serious conditions, these could be caught earlier with higher engagement with primary care.

·         Reduction in health disparities: The Health Foundation[9] notes that certain demographic groups, including those from socioeconomically deprived areas, report worse access to primary care and subsequently poorer health outcomes. Ensuring better access to GPs and other primary care services is vital for addressing these health disparities​.

What is currently being done

The shift left in healthcare is not just a theory or plan. Much is being done to boost primary care offerings and increase access to healthcare support earlier.

·         Delivery plan for primary care access: The NHS launched a plan in 2023 to “tackle the 8am rush”, referring to the number of people calling GPs at that assigned time to try and get an appointment. This is key to shifting treatment to primary care – getting access. The three main tactics here include empowering patients through tools, ‘Modern GP Access’, and building capacity within primary care providers.

·         Training for care navigators: Part of the plan is aimed at providing better training for GP staff to guide patients to the most appropriate care to help reduce unnecessary GP appointments. For example, it would empower GP staff to suggest self-care where they feel it’s suitable to prevent a GP appointment. Around 6,000 GP staff have registered for the training so far.

·         Expanding self-referral services: From September 2023, the NHS expanded self-referral services for conditions like musculoskeletal issues and podiatry. This would, in theory, allow around 30,000 people to access their required care directly each month​.

·         Boosting pharmacy services: Pharmacies are to be used like a triage service through a ‘Pharmacy First’ approach. Services such as blood pressure monitoring and oral contraceptive prescriptions are now available at pharmacies, removing the need to visit GPs. This, along with other tactics, could reduce GP appointments by 10 million a year.

·         Digital tools: While digital tools might not work for everyone, they are a vital tactic to move primary care from face-to-face to virtual. The NHS has introduced digital telephony and online consultation tools to both streamline appointment booking and improve patient access to services​.

·         Proactive care for certain demographics: Proactive care for people living at home with moderate to severe frailty has been prioritised. This tactic, which includes comprehensive assessments and personalised care plans, could help maintain independence and prevent hospital admission.

·         NHS Prevention Programme: This initiative aims to boost early detection - and hopefully prevention of - diseases such as diabetes, cardiovascular conditions, and cancer. It is focussed on areas of deprivation, where such diseases are more common.

Graphnet’s work to support primary care

Graphnet has always been at the forefront of providing joined up healthcare solutions to help people access the type of healthcare they need, at a time and place that works for both the patient and the healthcare provider.

Markus Bolton added:

Population health data and analytics enables health and care providers to identify those that are most likely to end up in hospital without support – individuals with diabetes or cardiovascular disease, for example. Interventions can then be planned and measured earlier, reducing the possibility of them being admitted.

Data can also help pinpoint patients that are suitable for remote monitoring. Again, shifting care downstream and to the left.

To help NHS trusts and other providers with the shift left for healthcare, we have a number of tools and solutions available:

·         PHITA (Population Health Insights to Actions): Graphnet's PHITA system integrates analytics, shared care records, remote monitoring, and patient access tools to support proactive and preventative care. This system helps identify patients who need proactive support, allowing healthcare providers to create actionable, trackable care plans and manage these patients at home, reducing the need for hospital visits.

·         Data-driven decision making: Graphnet's platforms allow healthcare providers to analyse patient data on both an individual and demographic level to identify high-risk patient cohorts and implement targeted interventions. For example, in Slough, the use of population health data has helped identify residents in need of support, leading to tailored interventions such as mental health support and digital literacy programs​.

·         Remote monitoring and virtual wards: By implementing remote monitoring technologies, Graphnet supports continuous patient care at home, which helps in reducing hospital admissions and ensuring patients receive timely care. This approach has been successfully applied in care homes to improve outcomes for residents​.

·         Enhanced Shared Care Records: Graphnet’s shared care records allow seamless information sharing across different care providers, ensuring that all members of a patient’s care team have access to the necessary information. This improves coordination and efficiency in delivering proactive care​.

·         Supporting Health Inequalities Initiatives: Graphnet’s tools are used to address health inequalities by identifying and supporting vulnerable populations. Their data-driven approaches help in deploying resources effectively to areas and individuals most in need, such as those living in socio-economic deprivation.
