The learning events

Does the NHS have the ability to deliver the level of system-wide change required of it? How can its leaders learn the lessons – the must-dos, and the elephant traps – from past attempts of system change?

Through a series of learning events in May 2018, UCL and Kaleidoscope Health & Care explored the implications of the reconfiguration of stroke services in London and Greater Manchester for system-wide change in the NHS in England.

This included new findings from research led by University College London on how to make and sustain major system change. The events
 shared learning across a wide range of clinical areas and perspectives, helping participants deliver change for the better.

The changes

Background
Major health system change involves reorganisation of services, at the regional level, and may include significant alterations to a care pathway. One such change is service centralisation, whereby aspects of service provision across a region are concentrated in a reduced number of hospitals.

Significant changes in provision of clinical care in the English NHS have been discussed in recent years, with the proposal to concentrate specialist services in fewer centres serving larger populations. Clear evidence of unacceptable variations in quality of care has prompted radical reorganisation (or ‘reconfiguration’) of stroke services in several regions of England.
​
​The changes studied
The evaluation of major system change in acute stroke services was funded by the NIHR Health Services and Delivery Research programme, and ran from 2011 to 2017. It focused primarily on the process and impact of centralising hospital stroke services in London and Greater Manchester into specialist hyperacute stroke units.

​The changes are summarised below.

Before the changes: London and Greater Manchester
Picture
  • Before centralisation, in both London and Greater Manchester, suspected stroke patients were taken to the nearest A&E department to receive stroke care.
  • Both areas centralised their hospital stroke services into ‘hub and spoke’ models, consisting of a reduced number of ‘hyper acute’ stroke services providing acute stroke care up to 72 hours following stroke (hubs), with a larger number of services providing care beyond this acute phase (spokes).

London centralisation
Picture
Implemented 2010; sustained throughout study.
  • Eight services were designated as Hyper Acute Stroke Units (HASUs), admitting suspected stroke patients 24h per day, 7 days per week (24/7), and 24 as SUs and TIA services, while five services were decommissioned.
  • All stroke patients were eligible for treatment in a HASU; All HASUs admitted suspected stroke patients 24/7.

Greater Manchester initial centralisation - ‘Greater Manchester A’​
Picture
Implemented 2010:
  • Three hyperacute services were designated: one Comprehensive Stroke Centre (CSC) and two Primary Stroke Centres (PSCs); 11 District Stroke Centres (DSCs) provided post-4h care and ongoing acute rehabilitation services. No stroke services were decommissioned.
  • Only stroke patients presenting within 4h of developing stroke symptoms were transferred to a CSC/PSC.
  • The CSC admitted patients 24/7; PSCs only admitted  in-hours.

Further centralisation - ‘Greater Manchester B'
Picture
Implemented 2015:  
  • All stroke patients were eligible for treatment in a CSC/PSC (in-line with the London model);
  • The CSC admitted patients 24/7; PSCs admitted patients 7am-11pm, 7 days per week

The research

This was a mixed methods evaluation, drawing on combining quantitative methods (analysing what works at what cost) and qualitative methods (analysing factors influencing development, implementation, and sustainability of changes). analysis of “what works and at what cost?” with qualitative analyses of “understanding implementation and sustainability” in order to analyse major system change in acute stroke care in a range of settings across the English NHS.

Our research questions were:
  1. What are the key processes of and factors influencing the development and implementation of the acute stroke service reconfigurations?
  2. To what extent have system changes delivered process and outcome improvements?
  3. Have changes delivered improvements that stakeholders (e.g. commissioners, staff, patients and the public, and reconfiguration leads) think are worthwhile?
  4. Have changes delivered value for money?
  5. How is service reconfiguration influenced by the wider context of major structural change in the NHS?

The evaluation was a collaboration between stroke clinicians and academics based in London and Greater Manchester, and actively involved a wide range of other stakeholders, including stroke patients and carers, commissioners, and the voluntary sector. The research team included Chief investigator Professor Naomi Fulop, and co-investigators Professor Anthony Rudd, Professor Pippa Tyrrell, Professor Ruth Boaden, Professor Charles Wolfe, Professor Christopher McKevitt, Professor Steve Morris, Dr Angus Ramsay, and Rachael Hunter.
 
Key findings from this evaluation are summarised below. To date, our published research has been referred to in national policy (Five Year Forward View), clinical recommendations (RCP Stroke Clinical Guideline), and has been cited in several ‘case for change’ documents’, including in Greater Manchester, where further centralisation was implemented in March 2015.

Key findings

What works at what cost:
  • Centralised acute stroke services in urban areas are associated with reductions in patient mortality and length of hospital stay, and are cost-effective
  • Service models where all patients are eligible for HASU (rather than a selection) are associated with better outcomes
  • Centralised stroke services can offer patients and carers a good experience of care (despite the need to travel further). It is important that clear information is provided at every stage of care.
  • Impact on care and outcomes can be sustained over time
 
Development, implementation, and sustainability
  • Combining ‘top-down’ authority and ‘bottom-up’ clinical leadership can facilitate change
  • Important to engage all relevant stakeholders from planning stages onward
  • System-wide authority can help challenge resistance. In the absence of top-down authority, working across clinical networks and commissioners can help drive change
  • Consistent, adaptive leadership facilitates both implementation and sustainability in challenging contexts
  • Understanding how a range of factors (e.g. clinical, political, social, financial) influence different stakeholders’ views; potential tension between patients’ and others’ perspectives;
  • Considering patient and public involvement in terms of its strategic and intrinsic value, rather than in terms of its impact on service redesign
  • Service standards linked to financial incentives help ensure that services have the capacity to provide the right care at the right time.
  • ‘Hands on’ implementation can help services work towards meeting standards
  • Independent evidence (audit, research) can help build and maintain stakeholder ownership of changes
  • Change is not a one-off: important to attend to evidence and consider further change if appropriate.

Italicised findings are as yet unpublished.
