An organising framework for improving whole system flow

The need for a multi-level approach

Significantly reducing waste and waiting from local health and social care systems will require a joined-up development strategy operating at multiple levels (see Figure 3). At the care journey level, the tools and techniques of lean provide helpful insights into how to tackle bottlenecks and remove waste, delays and duplication. For this work to be successful, however, communities also need to invest in the improvement skills and capacity of front-line teams and organisations so that they are capable of continually improving the quality of the work they do. Senior system leaders within each local health and social care economy also need to identify and address the local issues that may impact effective whole system flow. Finally, national policymakers and regulators have a role to play in creating an environment that is conducive to improving whole system flow.

In developing and implementing a strategy across these levels, it is important to recognise that improving flow is much more than just a technical challenge. Behaviours and relationships matter as much, if not more. The ability of local health and social care economies to foster a culture of learning behaviour is critical. This culture is one where members of staff at all levels are in the habit of ‘repeatedly accumulating insights, improvements and innovations, and putting them to good use’, as Steven Spear put it. Equally valuable is the capacity to work collaboratively with people with different professional values and ways of working. In many cases, the success of large-scale change rests on the quality of these relationships.

Resilience is also crucial. On the shifting sands of the health and social care landscape – where new performance challenges are always emerging, strategic priorities and leaders come and go, and partnership arrangements are in a state of constant flux – it can be difficult to maintain enthusiasm and the momentum for change. Every change journey is pitted with obstacles and has points when things appear to be going backwards rather than forwards, putting hard-won gains in jeopardy. An ability to pick up the pieces after such setbacks and begin again is one of the most essential improvement skills, yet is rarely mentioned or appreciated.

The rest of this section provides an overview of what is needed, at each level, to improve whole system flow. Sections 3 to 6 discuss what is possible at each of the four levels in more detail.

Care journeys

In looking to improve whole system flow, it is important for the work to be underpinned by a sound understanding of what it is like for patients and service users as they flow from one service to another. Anyone who requires care for acute or chronic conditions is likely to have a care journey that crosses multiple professional and sectoral boundaries in both community and institutional settings.

Focusing on the experiences of patients and service users will not only help to reveal examples of waste, delay and duplication within care processes, it will also ensure that priority is given to the aspects of care that matter most to those receiving it. After all, the overriding purpose of any effort to improve whole system flow should always be to provide an improved experience and better outcomes for patients and service users.

Getting care journeys to flow more smoothly at every point, so that patients and service users have a good experience, regardless of which team or service is providing their care, is a considerable challenge. As has already been noted, most efforts to improve flow have not attempted to tackle whole care journeys, but have concentrated on the in-hospital element. There is a pressing need to broaden the focus of attention to cover every team, service, profession and organisation that has a role to play in the care journeys of patients and service users.

Front-line team and organisational capabilities

The care journey level is the primary focus when thinking about improving flow, but it is also important to think about the contribution of each front-line team along that journey. Womack and Jones argue that for systems to operate effectively, each step in the process must be ‘capable’, so that it produces a good result every time.

If parts of the system are under-resourced or poorly designed, then well-meaning efforts to create flow may only lead to a slightly more joined-up collection of dysfunctional processes. For example, a hospital’s emergency department and wards may be operating effectively, but if social work support or community nursing teams are under-resourced or ineffective then waste and delays are inevitable. Similarly, efforts to strengthen out-of-hospital care might founder unless hospital pathways have been redesigned to prevent avoidable admissions, minimise length of stay and promote recovery. As the theory of constraints suggests, a chain is only as strong as its weakest link: movement along a process, or chain of tasks, will only flow at the rate of the task that has the least capacity.

This means that investment in continuous quality improvement at the team or unit level is vital. As well as having the right skills and resources, teams need to be able to work effectively alongside each other. For this to happen, teams at each part of the care journey ideally need to understand the same improvement language, and have experience of using similar improvement methods and tools. A shared understanding of what the system is and what the teams are collectively trying to achieve is also key. Experience among those that have developed successful approaches to integrating care shows that the co-location of staff from different disciplines and agencies can be helpful in breaking down cultural barriers.

It is also important to recognise that an understanding of improvement methods and tools at team level is not enough in itself to secure meaningful change., It has to be accompanied by willingness and capacity to spend time studying the system and identifying the constraints preventing effective flow. Understanding what matters to patients and service users, and focusing on how to improve their experiences, is also critical. Change programmes that focus largely on the spread and uptake of tools and techniques will often only achieve minor process improvements that are hard to sustain. The improvement journey of Winona Health in the US, which is explored in Case study 4, illustrates this point well. Winona’s information approach has shifted from one that was largely focused on tools and projects in its early years, to one that now focuses on ‘deep cultural change’ across the organisation and understanding what matters most to patients and the wider community.

Local health and social care economy enablers

Any attempt to improve whole system flow across an entire local health and social care economy needs to be underpinned by an effective infrastructure for collaboration. Financial incentives and contracting arrangements, information governance, service models and workforce challenges all need to be tackled. These issues cannot be addressed successfully by local system leaders without attention being paid to leadership, culture and the effective engagement of staff, patients, service users and communities. Failure to tackle them will inevitably frustrate efforts to improve the flow of patients, service users, staff, information and resources across organisational and sectoral boundaries.

As things stand now, the barriers to effective collaboration across organisational boundaries probably outweigh the enablers. At a time of severe financial pressures and mounting demand, many organisations and services are, perhaps understandably, more focused on dealing with their own immediate crises rather than the needs of the entire local health and social care economy. When opportunities for collaborative working among system leaders do emerge, it is not uncommon for the conversation to be dominated by structural and governance issues, rather than the deeper question of how to improve the relationship between the processes and teams within the economy.

Part of the problem is that emerging partnerships are often unable to dedicate sufficient time and resources to make the most of their collaboration. Participants hardly ever get the chance to get to know each other before embarking on a series of formal meetings and negotiations. Yet informal conversations are often crucial in building strong, trusting relationships and in surfacing concerns and potential obstacles at an early stage. Having the right skills to collaborate with others or to facilitate collaboration is essential: good intentions alone are not enough.

To achieve genuine whole system flow, local health and social care economy leaders need the capability and capacity to collaborate effectively and focus on the key issues this report has already described.

National system change levers

In what is still a highly centralised health and social care landscape, national bodies across the UK have a pivotal role to play in creating the right conditions for local change and helping to maintain its momentum over time. The activities they undertake tend to fall into three categories:

  • First, national bodies have the ability to ‘direct, prod, or nudge’ local organisations into change through the financial, regulatory or performance management levers at their disposal.
  • Second, they can support change through nationally led programmes or by investing in local improvement and leadership capability. However, to date, rather more attention and resources have been expended, in England at least, on ‘exerting regulatory control than on supporting improvement’.
  • The third way in which national bodies can influence change is through the national mechanisms governing the training, recruitment, employment and regulation of people who work in the health and social care system.

A key challenge for national bodies is to ensure that the levers they deploy are aligned. In England, for example, measures to promote whole system working through Sustainability and Transformation Plans (STPs) and new models of care have to be backed up with regulatory and performance nudges that are informed by a shared understanding of how to achieve change. Ideally, they should also be designed, planned and introduced in a joined up way. Action by national commissioners and support and oversight bodies (eg NHS England and NHS Improvement) needs to be in sync with the action taken by regulatory bodies (eg the Care Quality Commission) to monitor, regulate and inspect services. In some cases, national programmes are up and running before regulators have been able to develop a strategic response and turn it into a comprehensive and integrated set of activities. Meanwhile, measures that were developed for a different purpose and are now outdated – for example, the Payment by Results tariff system – need to be reviewed, as they could undermine the drive towards integrated working. Equally, action is required at national level to help address regional and sector-related staff shortages, as well as the high levels of staff turnover and reliance on temporary or agency staff, which could seriously impede local change strategies.

Crucially, national bodies across the UK have a responsibility to provide local system leaders with the time and space they need to deliver genuine transformation. At present, there is risk of a disconnect between an understandable focus from regulators on short-term performance and the long-term steps that health and social care economies need to take to deliver sustainable change. This question will be explored in more detail in Section 6.1.

Case study 1: The Flow Cost Quality programme

The Flow Cost Quality programme, which ran from 2010 to 2012, involved two trusts in England: Sheffield Teaching Hospitals NHS Foundation Trust and South Warwickshire NHS Foundation Trust.

The programme was set up to help the trusts examine their emergency care pathways and to develop ways in which capacity could be better matched to demand, thus preventing waste and poor outcomes for patients. Both trusts were encouraged to use a structured problem-solving methodology – the lean A3 improvement process – which is designed to enable teams to identify, frame and then act on problems and challenges. The process takes its name from the A3-sized problem-solving charts developed by engineers at Toyota. ‘A3 thinking’ has been described as being ‘the key to Toyota’s entire system of developing talent and continually deepening its knowledge and capabilities’. The approach encompasses a set of structured steps to:

  • describe the scope of the issue or problem and the measures for improvement
  • understand the current state from both the providers’ and customers’ perspectives
  • collect and analyse data to better understand the nature of the problem
  • develop a ‘future state’ plan with non-value adding activities being eliminated and a smoother flow established
  • agree and implement a programme of improvement projects to implement that plan using a rapid cycle of ‘plan, do, study, act’ (PDSA) to test out potential improvements
  • continuously monitor progress, evaluate results and feed back learning.

One version of an A3 working document, which is designed to be updated by teams after each iteration, is set out in Figure 4.

In Sheffield, there was an emphasis on bringing key stakeholders from across the pathway together in the same place to work collectively on identifying and solving problems. This was known as the ‘Big Room’ approach – or by the Japanese term ‘Oobeya’. The participants in each weekly meeting included clerks, secretaries and managers, as well as clinicians and allied health professionals from acute, primary, community and social care settings (see Figure 5).

Attendance was voluntary, and facilitators endeavoured to create an open, honest and collaborative atmosphere in which each individual, regardless of their position in the hierarchy, felt empowered to contribute on an equal footing. Attendees were also encouraged to see the Big Room as part of a process of continuous improvement, through which they would discover their way to a solution through small tests of change, rather than a discrete time-limited project geared towards implementing a pre-ordained solution.

The Flow Cost Quality team in Sheffield focused on the care of frail older people. They identified significant delays in patients being referred to hospital as an emergency by GPs and subsequent delays at each stage of the process. As a consequence, two-thirds of frail older patients arrived on the medical assessment unit after 6pm in the evening when there were fewer senior staff available to assess them. Most had to wait until the following morning to receive a review by a senior clinician.

The team implemented a range of changes to reduce batching and delays and to improve the quality of care. These included the introduction of a frailty unit, which brings together in one place all of the specialist medical, nursing and therapist staff who deal with frail older people. The team also developed an innovative model known as ‘discharge to assess’, which allows frail older patients to be discharged home as soon as their acute medical needs have been met. Within a few hours of the patient’s arrival at home, the trust’s community staff assess their continuing care, equipment and ongoing rehabilitation needs.

The team in South Warwickshire, meanwhile, worked on emergency care for all adult patients. As in Sheffield, they began by mapping processes and testing changes using a PDSA approach. Innovations included ways of matching consultant availability to variation in demand, and bringing senior clinical assessment closer to the start of the process. There was a particular focus on ensuring that support processes were capable and aligned in order to facilitate flow. For example, the number of same-day blood test results available on ward rounds was increased from less than 15% to more than 80%. Because of these up-to-date results, consultants were able to make quicker and safer clinical decisions for patients.

The Flow Cost Quality programme produced encouraging results in both trusts, which have been sustained over time. Moreover, the improvement approach underpinning this success has been spread more widely across the trusts and the local health and social care system.

In Sheffield, the ‘discharge to assess’ model – which began with a small test of change with one patient on one ward – has now been spread throughout the city’s hospital system. More than 10,000 patients have now been transferred out of the hospital into a service called ‘active recovery’, which is a health and social care collaborative aimed at ensuring that their needs are met and addressed in real time. This has resulted in a reduction in the length of time from completion of medical care to home support from 5.5 days to 1.2 days. The Big Room process, meanwhile, is now being used to help improve flow along a series of other care pathways within the city. It has also spread to Wales, where it has proven to be one of the most widespread and valued elements of the Welsh 1000 Lives Patient Flow programme.

South Warwickshire has reported a nine-point fall in mortality rates from 1.11 in 2011/12 to 1.02 in April 2015. Over the same period, the length of acute stay for all patients fell from 7.7 days to 6.2 days, while the reduction for patients aged over 75 was even greater – down by 3.1 from 12.6 days to 9.5 days. Crucially, this reduction in length of stay has not been accompanied by an increase in emergency readmissions. The trust has also managed to cut the proportion of patients who had to make more than three bed moves during their time in hospital from 14% to just 2% between 2011/12 and April 2015. It has also developed its own successful discharge to assess initiative, which is built on effective partnership working with local primary, community and social care providers.

** An effective health and social care system is one in which individuals are able to engage with services at a time and in a place that is appropriate to their needs and wishes. While each journey is different, it is possible to identify some common processes which are amenable to standardisation and can deliver improved flow.

†† The suite of programmes and guides on whole systems working that were developed by the NHS Modernisation Agency and the NHS Institute for Innovation and Improvement, highlighted in Section 1.1, are good examples.

‡‡ For example, by 2012, Sheffield had achieved a 37% increase in patients who could be discharged on the day of admission or the following day with no increase in the readmissions rate. The trust also reported a decrease of in-hospital mortality for geriatric medicine of around 15%.
