1 Introduction
In this Element, we identify the potential and challenges of using collaboration-based approaches to support improvement in healthcare. We review a range of approaches, summarising some of the evidence about their role, value, and limitations. We conclude by discussing the implications for those considering using such approaches in practice. Our focus is on collaboration-based approaches led primarily by healthcare staff, since this is where much of the academic literature has focused. Some other approaches focus on the contribution of patients and carers – for example, those addressed in the Element on co-producing and co-designing.Reference Robert, Locock, Williams, Dixon-Woods, Brown and Marjanovic1
2 What Are Collaboration-Based Approaches?
One of the most enduring lessons of research in healthcare improvement is that improving quality requires systems for sharing knowledge, coordinating and organising activity, and encouraging cultures that are supportive of improvement. In this context, the promise of collaboration-based approaches to improvement has become a focus of increasing interest, activity, and study.Reference Aveling, Martin, Armstrong, Banerjee and Dixon-Woods2
Though the literature on collaboration is rapidly growing and developing, a universal definition has proven elusive. In part, this is because, as we shall see, many different collaborative forms have emerged. The unifying feature of collaboration-based approaches however is that they involve groups working together around shared improvement goals.
Another crucial feature of these approaches is that they are based on networks.Reference Goodwin, Peck, Freeman and Posaner3,Reference Powell4 Networks are ubiquitous in everyday life – they connect parents whose children attend the same school, colleagues who share the same professional background or workplace, and people who play a team sport, for instance. Networks enable multiple forms of relationship-based exchange, allowing people, for example, to share contacts or exchange favours.Reference Aveling, Martin, Armstrong, Banerjee and Dixon-Woods2 They have a particularly important role in the speedy and efficient exchange of knowledge,Reference Powell4 including the know-how formed within a particular community. This kind of ‘non-canonical’Reference Brown and Duguid5 knowledge (the sort that concerns how things are really done in practice) is especially valuable because it is frequently implicit or unspoken, practice-based, and often difficult to articulate or formally describe.Reference Greenhalgh and Wieringa6 Networks are not, of course, just circuits for information exchange.Reference Jones, Hesterly, Borgatti and general7,Reference Börzel8 They also exert powerful effects on norms, values, and behaviour – in other words, the culture of the group involved.Reference Swedberg9
Though a collaboration cannot exist without a network, a network on its own does not equate to a collaboration. Networks may exist without any common mission, but collaborations are purposeful. Additional characteristics of collaborations in healthcare contexts include a commitment to cooperating and contributing in pursuit of that purpose and an ethos of learning. These features tend to foster trust and reciprocity: if a collaboration works well, it can generate a virtuous circle in which mutual benefits encourage further investment of time and effort, resulting in further benefits. We therefore offer the following definition.
In healthcare, a collaboration-based approach to improvement involves a network of people who come together to cooperate around a common interest, with a shared goal of improving care and mutual learning.
In this basic formulation, collaboration-based approaches can be readily recognised as consistent with the long-standing principles and values of community that underpin the healthcare professions,Reference Freidson10 particularly when they are empowered to set their own rules and enforce them through peer influence.Reference Yeung and Dixon-Woods11,Reference Parsons12
Several types of collaboration-based approach to healthcare improvement can be identified, ranging from informal communities of practice at one end of the spectrum through to managed clinical networks at the other, with many other forms (e.g. quality improvement collaboratives, clinical communities) somewhere in the middle. They vary in their origins, degree of formality, and exclusivity of membership, and in the methods used to achieve their goals. Although collaborations are sometimes described as professionally ledReference Martin, Armstrong, Aveling, Herbert and Dixon-Woods13 or bottom-upReference Bate, Robert and Bevan14 improvement approaches, the degree to which they exhibit these features varies. In Section 3, we explore a small selection of the various approaches available.
3 A Selection of Collaboration-Based Approaches
Collaboration-based approaches to healthcare improvement vary in form and origin. Some were developed primarily in a healthcare context; others have their roots in quite different fields. They also vary in the extent to which they are focused explicitly and primarily on improving quality and patient safety, the extent to which they are naturally occurring or deliberately formed, and the formality with which they are organised and coordinated.
To illustrate this range, we describe four collaboration-based approaches: quality improvement collaboratives, managed clinical networks, communities of practice, and clinical communities. These approaches are not exhaustive. They are chosen because they vary in how much they tend towards control, self-organisation, and professional ownership.
3.1 Quality Improvement Collaboratives
Some collaboration-based approaches are highly organised, featuring an extensive and well-documented infrastructure, prescriptions for organisation, and specified activities, events for interaction, and timetables. Among the most prominent and best-known examples of this kind of approach are quality improvement collaboratives.
Collaboratives typically focus on a specific clinical topic (such as a presenting condition, pathway, or intervention) – often one in which large variations in care or gaps between current and best practice are known to exist. They involve creating a network of people from several organisations (or occasionally within organisations) and multi-professional teams around defined improvement goals. A core group or faculty works on periodically convening members of the network, coordinating its members, establishing shared goals, and providing infrastructural support, such as a database or registry to which participants submit data, using indicators with standardised definitions and methodologies.Reference Plsek15,Reference Schouten, Hulscher, van Everdingen, Huijsman and Grol16 Participating sites receive feedback, usually benchmarked against other sites, and attend face-to-face or virtual meetings to discuss progress and identify interventions that might be used to support improvement. These features, while typical, are not invariable: quality improvement collaboratives take many different forms.
3.1.1 Growth of Collaboratives in North America
Some of the early collaboratives originated in North America.Reference Plsek15 An important example is the Vermont Oxford Network.Reference Horbar, Rogowski and Plsek17 This not-for-profit organisation was established in the late 1980s to improve the quality and safety of care for newborn infants and families through a coordinated programme of research, education, and quality improvement. Now involving more than 1,200 hospitals worldwide (including around 800 in the USA), it is organised around a network of healthcare professionals who work together as an interdisciplinary community. All members of the network contribute data to high-quality databases on interventions and outcomes for infants under their care. Key to the approach is the use of uniform and standardised definitions for data collection. Members are given detailed, confidential, risk-adjusted reports that allow them to track their data over time and measure the performance of their unit against others.
The Vermont Oxford Network has much in common with another well-known collaborative: the Northern New England Cardiovascular Disease Study Group, also founded in the late 1980s. A voluntary consortium, it initially focused on hospitals across three US states that were seeking to improve outcomes of coronary artery bypass graft surgery. By gathering standardised data from all hospitals, the collaborative identified variations in mortality after surgery that could not be explained by case-mix. It undertook a three-component improvement programme, which involved giving benchmarked performance feedback to participating centres, training courses in continuous quality improvement, and team-based visits to all sites.Reference Finks, Dimick and Greenberg18
A similar, though somewhat later, movement took place in the US state of Michigan in 1997. Hospitals began to work with Blue Cross Blue Shield of Michigan (a health insurer), which owns the Blue Care Network (a health maintenance organisation), to study variation in outcomes of angioplasty services. By 2004, Blue Cross Blue Shield of Michigan was investing in statewide quality improvement initiatives in a variety of clinical specialties. The Michigan collaboratives are now a large-scale enterprise, involving programmes across several different clinical fields (Box 1). All the programmes use clinical registries, with hospitals and clinicians submitting data and receiving feedback on their performance from their registry coordinating centre. Participating healthcare organisations convene to interpret and review their data, often focusing on variations. Best practices are identified and implemented across regions.Reference Share, Campbell and Birkmeyer19
Box 1 The Michigan collaboratives’ programmes
The Michigan collaboratives’ programmes have reported some striking improvements in the quality and safety of healthcare services, sometimes outperforming both secular trends and improvements made by other improvement programmes. One example is the Michigan Surgical Quality Collaborative. Focusing on general and vascular surgery, it is the largest and most mature of the Michigan collaboratives. Between 2005 and 2009, participating hospitals reduced risk-adjusted morbidity rates (the primary outcome measure of the American College of Surgeons’ National Surgical Quality Improvement Program, NSQIP) from 13.1% to 10.5%, outperforming results achieved by participants in NSQIP.Reference Share, Campbell and Birkmeyer19
The Michigan Bariatric Surgery Collaborative has also produced impressive improvements, including a reduction in the overall rate of perioperative complications among participating hospitals from 8.7% to 6.6% in the first two years of the programme (2007–09).Reference Share, Campbell and Birkmeyer19 More recently, in 2012–14, the Michigan Urological Surgery Improvement Collaborative achieved a 53% reduction in infection-related hospital admissions following transrectal prostate biopsy, among participating hospitals.Reference Womble, Linsell and Gao20
Key to these collaboratives’ achievements seems to be the use of high-quality, clinically relevant data; site visits; collaborative learning; treating practice variation between hospitals as natural experiments in what works and what doesn’t; rapid and robust assessments of relationships between process changes and outcomes; and improvements in safety culture associated with peer-norming effects.Reference Share, Campbell and Birkmeyer19
Several of these kinds of large, often statewide collaborative have endured over time, with many – perhaps crucially – distinguished by their commitment to research as well as to quality improvement. The Vermont Oxford Network, now over 30 years in existence, continues to meet three times a year. As well as supporting quality improvement, it uses its platform to conduct observational studies, intervention studies, and research on the role of differences in the structure and organisation of units in explaining patient outcomes.Reference Horbar, Soll and Edwards21 By so doing, it has made a substantial contribution to the evidence base for neonatal care. The Northern New England Cardiovascular Disease Study Group remains similarly active. The Michigan collaboratives’ programmes, though newer, continue to thrive, with large numbers of published studies.
A rather different, though very popular, model of a collaborative is the more time-limited, topic-specific approach offered by the Institute for Healthcare Improvement’s (IHI) Breakthrough Series. Conceived by the IHI’s founders in 1994, a Breakthrough Series collaborative is time-bound (often in the range of 6–15 months) and usually involves three face-to-face learning sessions between participants drawn from several organisations. Central to the theory of change – the assumptions about how its activities will give rise to the intended outcomes (see the Element on evaluationReference Tarrant, Armstrong, Ling, Evaluation, Dixon-Woods, Brown and Marjanovic22) – is that those involved must have a clear objective, a clear means of measuring whether that objective has been achieved, and a notion of what is needed to make that change happen. Box 2 summarises the blueprint for running a Breakthrough Series collaborative.24 The detailed blueprint includes recommendations about the numbers of organisations and individuals that should be involved, the timing of meetings, the relationship to other improvement methods (such as the IHI’s Model for Improvement), the role of expert faculty in guiding improvement, and the intended outputs and outcomes.24 Various how-to guides are available.Reference Hulscher, Schouten and Grol25,Reference Øvretveit, Bate and Cleary26
As we discuss later, studies of Breakthrough Series collaboratives provide useful insights into whether and how they work. However, Breakthrough Series collaboratives do not themselves, unlike some of the collaboratives mentioned earlier, set out with research as one of their primary goals. Their outputs are usually (though not invariably) published as quality improvement reportsReference Ogrinc, Davies and Goodman27 rather than as research articles.
Box 2 Key elements of the IHI’s Breakthrough Series collaborative approach
(1) Topic selection: the topic should be ripe for improvement efforts: for example, there may be a demonstrable gap between evidence and its use in practice that has important consequences for patients and that is tractable to improvement.
(2) Faculty: as part of the package of support available to organisations, 5–15 experts in relevant disciplines, including those with improvement expertise, are asked by the collaborative’s convenors to form a faculty of subject matter experts and individual clinicians. The faculty develops content for the collaborative – for example, aims, measurement strategies, and the evidence-based changes to be implemented.
(3) Enrolment of participating organisations and teams: organisations are asked to identify multidisciplinary teams to join the collaborative. Senior leaders in organisations are expected to provide guidance and encouragement and to take responsibility for sustaining improvement after the collaborative dissolves. Participating teams are expected to attend collaborative meetings and activities, seek to implement changes in their own practices, and promote changes as standard practice locally.
(4) Learning sessions and action periods: a typical collaborative involves three face-to-face meetings between participating teams and expert faculty. These are interspersed with action periods, when teams seek to test and implement changes and collect data on their impact. The first learning session presents a vision for improvement and outlines the specific changes needed to achieve it. During the second and third learning sessions, teams report on their successes and failures and learn from each other to improve their future efforts (e.g. through plenary sessions, workshops, and informal dialogue and exchange).
(5) Quality improvement methods: the IHI recommends that collaboratives use the Model for Improvement (see the Element on the IHI approachReference Boaden, Furnival, Sharp, Dixon-Woods, Brown and Marjanovic23) during action periods to ensure a systematic approach to change. This involves agreeing on specific and measurable aims, collecting data and measuring improvement over time, identifying key changes that are expected to result in improvement, running a series of plan-do-study-act cycles that seek to test the changes and their results, and learning from the findings to inform further efforts.
(6) Summative outputs: at the end of the collaborative, teams have a final face-to-face meeting to present their results to each other and to groups beyond the participating organisations, ensuring wide dissemination of learning and spread of ideas.
(7) Measurement and evaluation: throughout the process, participating teams are expected to maintain run charts tracking their progress through time, and faculty members review monthly reports from participating teams to keep track of the collaborative’s overall progress.
3.1.2 Collaborative Approaches in the UK
The UK has not had the same trajectory as the USA in terms of adopting and using collaboration-based approaches. Although Breakthrough Series collaboratives were the government’s chosen strategy for improvement in the National Health Service (NHS) in the early 2000s and were promoted by the NHS Modernisation Agency, they struggled to be adopted at scale. Those that were initiated tended to suffer from various problems, including haphazard reporting of outcomes and poor collection and interpretation of data.Reference McLeod and Peck28 Some important examples of collaboratives nonetheless emerged from this period, including the Cancer Services Collaborative and the Orthopaedic Services Collaborative, but while they did valuable work, neither may have delivered fully on the promise of the approach.Reference McLeod and Peck28
Perhaps the UK’s nearest equivalents to the large US statewide collaboratives led by clinicians (such as the Michigan collaboratives’ programmes) are the audits and registries established by royal colleges, professional societies, and others from the late twentieth century onwards. An early example is the monitoring of survival rates after cardiac surgery through voluntary submission of data to the Society of Cardiothoracic Surgery, which began in 1977.Reference Amess, Walshe, Shaw and Coles29 Clinical audit in the UK, as in many countries, is now a large-scale enterprise involving around 70 national exercises in collecting process and outcome data across a range of settings with many stakeholders. Around 30 are operated by professional groupings (such as the royal colleges) as part of a national managed scheme: the National Clinical Audit and Patient Outcomes Programme. Funded by NHS England and the Welsh Government, these audits are commissioned by the Healthcare Quality Improvement Partnership, a consortium comprising the Academy of Medical Royal Colleges, the Royal College of Nursing, and National Voices (a patients’ charity).
Originally, the early registries and audits in the UK were largely voluntary, professionally led enterprises. Participation in the National Clinical Audit and Patient Outcomes Programme is now mandatory for NHS organisations in England, following the introduction of a contractual requirement in 2012. Data from the audits can be mobilised for several purposes, including quality assurance, pay-for-performance schemes, and inspection and regulation. As a result, these audits have assumed a somewhat hybrid character: though many are still led and organised by professional groups, they are funded by government and have become part of the NHS system of performance management. Though many audits have demonstrated improvement in processes and outcomes over time, they have, particularly as they have been absorbed into the performance-management architecture, lost some of the features of collaboration that characterised the early efforts. Further, the principal means of quality improvement has often remained data collection and feedback (see the Element on audit, feedback, and behaviour changeReference Foy R, Dixon-Woods, Brown and Marjanovic30), and the deployment of structured quality improvement methods and collaboration-based efforts remains patchy and inconsistent.
Some important collaboration-based examples with features similar to those of long-term collaboratives, like the Michigan collaboratives’ programmes, have nonetheless emerged. They include the National Audit Projects run by the Royal College of Anaesthetists, which have addressed important problems in surgery using a characteristically community-based approach that includes clinicians and patients as part of the collaboration.31
3.2 Managed Clinical Networks
Some collaboration-based approaches to improvement have been in some sense managed from the start: rather than originating from voluntary association between individuals or professional groups with a common interest or goal, they have been initiated by policymakers or managers.
In the UK, the Labour government of 1997–2010 is particularly associated with a renewed interest in the power of collaboration. Key thinkers had become disillusioned with the effects of both traditional hierarchical approaches to governing public services and the market-based, competition-oriented reforms that had been introduced from the late 1980s onwards.Reference Newman32 Collaboration-based approaches were seen as drawing on professionals’ intrinsic motivation to provide high-quality services and to work together to improve provision. The creation of networks between organisations and professionals was also seen as a key way of ensuring that public services could address ‘wicked issues’: challenges that are complex and multifaceted, and are therefore beyond the ability of any one organisation to handle in isolation.
These collaborative networks were introduced in various fields to facilitate joint effort and knowledge sharing, with the aim of solving problems and improving public services.Reference Martin, Currie and Finn33 A prominent example in healthcare is the introduction of managed clinical networks in cancer provision and other areas of the NHS in the early 2000s, to promote ‘interorganizational collaboration, partnerships and a weakening of the vertical lines’ of accountability.Reference Addicott, McGivern and Ferlie34 Cancer networks were introduced in response to policy reports that high-quality care was being impeded by poor dissemination of evidence and good practice. The networks sought to formalise and provide an infrastructure for lateral relationships that had previously been informal and patchy, creating opportunities for dialogue among staff and organisations that might promote knowledge sharing, and facilitating peer review to inform service improvements. They aimed to go beyond building links between clinicians separated by organisational boundaries and to provide a basis for agreements about responsibilities, care pathways, and service specifications.Reference Cropper, Hopper and Spencer35
The cancer networks were better resourced financially and managerially than many forms of collaboration. But the available evidence suggests that their impact was limited by the wider context in which they were introduced, and by the form in which they were realised. For example, Addicott et al. report that, for all their collaborative intent, cancer networks were infused with the performance management culture that was dominant at the time.Reference Addicott, McGivern and Ferlie34 Though originally conceived as a vehicle for professional education and multidisciplinary training and development, their focus quickly shifted towards coordination of services and the measurement of performance.Reference Addicott, McGivern and Ferlie36 The result was that the networks became, in many cases, little more than an extra vehicle for the achievement of targets. Managerially controlled rather than professionally owned, they were criticised for ‘the managerial element driving out some of the pre‐existing networks between clinicians’.Reference Addicott, McGivern and Ferlie34
An important lesson of managed clinical networks, therefore, is that the values and behaviours of a collaborative network can become dominated – perhaps even undermined – by hierarchical command, market-based competition, and other forms of directive control in the wider environment. As we discuss later, other collaboration-based approaches may face similar challenges.
3.3 Communities of Practice
If managed clinical networks are at one end of the spectrum of collaboration-based approaches, communities of practice are at the other. Developed in the field of educational psychology, the origins of the concept are distinctive. Lave and Wenger proposed the community of practice not as a planned way of making change, but as an analytical description of the way newcomers are socialised into different forms of community.Reference Lave and Wenger37
These communities may be very different, including, for example, occupational groups (e.g. midwives) or people with a common interest or identity (e.g. Alcoholics Anonymous). What such groups have in common, argue Lave and Wenger, is that becoming a member involves a form of apprenticeship (which they term ‘legitimate peripheral participation’), through which newcomers learn how to behave as well as what to do, and start to acquire a group identity,Reference Lave and Wenger37 primarily through informal learning and interaction. Communities of practice as first conceptualised, then, were not interventions (for improvement or any other purpose), and they were not developed in the context of healthcare. Lave and Wenger’s contribution was to describe a process that took place naturally across several different kinds of settings.
Others quickly saw the relevance of the concept to other activities, including Brown and Duguid’s famous reanalysis of a series of ethnographic studies of Xerox engineers.Reference Brown and Duguid5 This work characterised the knowledge-sharing activities of a group whose professional expertise was seemingly threatened by increasingly intelligent photocopiers (which could supposedly identify and fix faults themselves) and by increasingly copious instruction manuals. Brown and Duguid found that, far from becoming a simple matter of following instructions, the work of the engineer remained one where know-how was crucial – and where the community of colleagues, who shared lunch, phoned each other, or gathered for after-work drinks, was an essential resource. Collective knowledge shared with colleagues, including tacit knowledge (such as heuristics, top tips, and workarounds) was at least as important as explicit, formal information.
Several authors – including Wenger himself – have since developed the concept of the community of practice as a more intentional intervention, not just a naturally occurring phenomenon. While Wenger et al. maintain that communities of practice cannot be engineered by organisations, they can be cultivated: organisations can generate the conditions in which communities of practice can emerge and flourish, and create innovative work-related insights that benefit staff and organisations alike.Reference Wenger, McDermott and Snyder38
Consequently, communities of practice represent a rather more open-ended approach to improvement than most other collaborative forms, as illustrated by the example in Box 3. They do not follow detailed instructions for how to organise and run themselves (in contrast to, for example, the Breakthrough Series approach). Communities of practice generally determine for themselves what they do, rather than having their activities chosen or imposed externally. Their interest is in developing sets of practices and capabilities, and they select areas of focus themselves on the basis of their work, knowledge, and commitment to the group.Reference Wenger and Snyder41
These are not hard-and-fast features. The labels in this field are often applied variably – for instance, we classified the Vermont Oxford Network as a quality improvement collaborative earlier, but it also self-identifies as a community of practice.Reference Horbar, Soll and Edwards21 Moreover, as we see later in Section 5, some argue that the concept and language of communities of practice have increasingly been co-opted as a rather crude tool for knowledge management.
Box 3 A community of practice in healthcare
Kilbride et al.Reference Kilbride, Perry, Flatley, Turner and Meyer39 discuss the development of a community of practice during the redesign of a stroke service in London. Complementing project management and implementation, and allowing knowledge sharing and a network of relationships to emerge, the community of practice was seen as fundamental to the successful introduction of a new stroke unit. It demonstrated four important features:
building an interprofessional stroke team (and breaching professional boundaries that had previously been rather impermeable)
developing practice-based knowledge and skills in stroke care (particularly tacit knowledge about the craft of care – things that cannot readily be codified, as Brown and DuguidReference Brown and Duguid5 emphasise)
valuing the central role of the nurse in stroke care (particularly making visible the extent to which high-quality stroke care is dependent on the contribution of this role)
creating an organisational climate for supporting improvement.
The community of practice came about not as a deliberate intervention, but rather emerged during the change process, facilitated by several features of how the change was organised. Team meetings ‘often had no pre-arranged agenda but were problem focussed’, offering a theme (or a ‘practice’ in Wenger-Trayner and Wenger-Trayner’sReference Wenger-Trayner and Wenger-Trayner40 terms) around which the community could congregate.
Though it was difficult to attract people to take time out of busy schedules to attend such unstructured meetings at first, quick wins encouraged a range of colleagues to attend. The approach also fostered a sense of community: mutual commitment and a ‘meaningful sense of shared identity that tied people beyond specific workplace exchanges’. Care was taken to nurture collegial relationships and to include the range of people affected by the changes, including managerial and clinical staff. Together, members of the community took the chance to think through the organisational implications of the change: what new competencies would be needed, what demands it would place on existing staff members, and how their coordination might need to change. The community of practice also fed back into the formal organisation of the change initiative, leading, for example, to the introduction of an interprofessional stroke committee comprising senior managers and stroke unit clinicians. This offered a means by which the community could influence wider organisational strategy.
Consistent with the original theory, the community of practice here was not the result of a formal decision or even intentional action: rather, it was ‘fundamentally self-established, being composed of staff who originally worked in a dispersed service’. But in bridging professional boundaries and creating a sense of common purpose and mutual commitment, it ensured that social dynamics – which can so often derail change projects that look good on paper – supported a smooth redesign of the service.
3.4 Clinical Communities
An evolution of collaboration-based approaches from the 2010s builds on learning about both the successes and limitations of quality improvement collaboratives, communities of practice, and network-based approaches more broadly: the clinical community approach (Box 4).Reference Aveling, Martin, Armstrong, Banerjee and Dixon-Woods2 The clinical community attempts to find the right balance between the self-organising, member-led ethos that underlies the idea of collaboration, and the need for administrative and managerial support to help a collaboration achieve its objectives.Reference Aveling, Martin, Herbert and Armstrong43 Box 5 presents an example of the approach in action, and what is needed to make it work.
Box 4 Principles of clinical communities
Aveling et al.Reference Aveling, Martin, Armstrong, Banerjee and Dixon-Woods2 set out eight lessons for those seeking to develop clinical communities as a form of collaboration-based healthcare improvement.
(1) Foster a strong ‘vertically integrating core’: a coordinating group to organise the collaboration and keep it on course towards its objectives. Collaborations do not organise themselves, and leadership is crucial (to ensure both effective administration and, when needed, managerial clout – see point 7).
(2) Start from a clear theory of change, but be prepared to learn and modify. It is important to consider in advance how the clinical community is going to make change happen, but not everything can be anticipated.
(3) Identify and provide the right resources and training. Technical knowledge, tacit know-how (as emphasised in communities of practice), and skills in change management and leadership are key.
(4) Hold the community together, and recognise and deal with coniflct and marginalisation. In practice, even highly functional communities tend to be ‘fragmented, hierarchical and involve relationships of conflict’: managing these tensions effectively is crucial to longevity and success.
(5) Foster a sense of community. Active intervention is required to identify a common goal and to develop relationships of mutual obligation.
(6) Collect and use data wisely. Good-quality data, and knowledge of how to make use of it, is vital to any improvement initiative (see also the Element on measurement for improvementReference Toulany, Shojania, Dixon-Woods, Brown and Marjanovic42). Data show what needs to be done and help people to monitor their progress – and can provide the basis for healthy comparison across settings.
(7) Find the balance between hard and soft tactics. Persuasion, negotiation, and compromise are fundamental to collaboration-based approaches, but sometimes harder tactics are needed. Sometimes communities need protection from external performance pressures; at other times, they can be mobilised to reinforce the importance of improvement.
(8) Recognise the importance of context: local contexts can influence the likelihood of success and create supportive conditions. The wider context, such as organisational culture or national policy, is likely to influence the preoccupations and priorities of members.
The clinical community approach recognises the power of collaboration and professionally led improvement, but is also explicit that some judicious use of control-based devices – including, for example, data to hold units to account – can be a helpful or even necessary complement to the collaborative ethos.Reference Aveling, Martin, Herbert and Armstrong43 The experience of managed clinical networks (described in Section 3.2), of course, illustrates the risks of going too far in this direction.
Box 5 Clinical communities in action
Aveling et al. compared two contrasting examples of clinical communities, deriving lessons about what is needed to make the approach work in practice.Reference Aveling, Martin, Herbert and Armstrong43 Three areas of activity seem important in creating enduring communities with the capacity to achieve improvement.
Mobilising diverse groups: both communities were successful in mobilising diverse groups of individuals from different backgrounds, including clinicians from various disciplines, managers, and to some extent patients. Both relied on well-connected vertically integrating cores, comprising individuals with credibility, authority, and strong backing from reputable institutions. Both sought to build a sense of community through, for example, meetings and virtual get-togethers.
Building lateral ties: one community was much more effective in building lateral ties across its members. In the other community, most interactions were mediated through the core team. While effective in the short term, this created vulnerabilities for the longer-term sustainability of the community, which remained highly dependent on the core team.
Achieving effective action: the two communities diverged in their success in moving their members from good intentions towards effective action. One focused its efforts on externally set performance goals that had to be met, and using the community as a supportive vehicle for their achievement. In the second community, a more diffuse set of goals, reliant on teams’ own priorities rather than a common shared ambition, made it more challenging to initiate change, and to drive it forward sustainably through measurement, comparison, and feedback.
The clinical community approach has been adopted and extended in clinical settings. For example, at Johns Hopkins Medicine in the USA, clinical communities are used as a forum to bring together a multidisciplinary membership with a focus on a particular population, clinical area, or patient safety issue in member hospitals.Reference Gould, Wachter and Aboumatar44 Some success in the use of the approach has been reported,Reference Frank, Thakkar and Podlasek45 though so far no trials have been conducted.
4 Collaboration-Based Approaches in Action
An extensive literature has examined collaboration-based approaches to healthcare improvement. Here, we focus on two of the most widely discussed approaches: quality improvement collaboratives and communities of practice. Systematic reviews and other studies in this area make clear that the evidence base for all collaboration-based approaches remains equivocal. There is still limited understanding of exactly which components of these complex interventions are most associated with change, and how apparently causal mechanisms operate. There is, however, a growing literature on how these approaches can be optimised to maximise their chances of making an impact.
4.1 Do Quality Improvement Collaboratives Work?
Quality improvement collaboratives have received much research attention, to the extent that they are now among the most studied of all improvement approaches in healthcare. However, one major weakness in the evidence base (in common with many other improvement approaches) is the risk of publication bias – that is, the non-reporting of studies that failed to demonstrate statistically significant improvement. Almost by definition, publication bias is difficult to detect or quantify. A second challenge, given the resource intensity of collaboratives (including organising events, getting input from expert faculty, and arranging cover for clinical staff to lead improvement locally), is establishing cost-effectiveness. Third, like many improvement interventions (see, for example, the Elements on evaluation,Reference Tarrant, Armstrong, Ling, Evaluation, Dixon-Woods, Brown and Marjanovic22 the IHI approach,Reference Boaden, Furnival, Sharp, Dixon-Woods, Brown and Marjanovic23 Lean and associated techniques for process improvement,Reference Radnor, Williams, Dixon-Woods, Brown and Marjanovic46 operational research approaches,Reference Utley, Crowe, Pagel, Dixon-Woods, Brown and Marjanovic47 and workplace conditionsReference Maben, Ball, Edmondson, Dixon-Woods, Brown and Marjanovic48), quality improvement collaboratives have some of the features of ‘black boxes’:Reference Wilson, Berwick and Cleary49,Reference Shaw, Chase, Howard, Nutting and Crabtree50 complex interventions with many components, which are often not made clear, and whose role in triggering the mechanisms that result in intended (and unintended) change is often left under-theorised or unexamined. A further practical and methodological challenge is that exactly how such complex interventions work is likely to vary by context rather than being exactly the same in every setting (see the Element on evaluationReference Tarrant, Armstrong, Ling, Evaluation, Dixon-Woods, Brown and Marjanovic22). These problems are compounded by poor reporting of the actual content of the collaboratives beyond their high-level focus and organisation, and of the degree to which the planned interventions were carried out as intended in practice (their fidelity). As Nadeem et al. note, the lack of description of ingredients, of what they are meant to achieve, and of what they actually achieve in practice is problematic for the evidence base for collaboratives.
As QICs [quality improvement collaboratives] continue to grow in popularity, this lack of detailed information makes it impossible to replicate successful QICs, to ensure that adaptations of QICs include key active ingredients, or to determine whether negative outcomes are related to the quality and fidelity of delivering this multicomponent improvement model or differential efficacy of QICs for different [evidence-based practices].Reference Nadeem, Olin, Hill, Hoagwood and Horwitz51
A recent (2018) systematic review of 64 studies of quality improvement collaboratives, predominantly focused on inpatient care topics,Reference Wells, Tamir and Gray52 illustrates some of the problems. The breadth of populations and intended outcomes – and of the forms of intervention that have been given the label ‘collaborative’ – made it challenging to synthesise the findings. Though the collaboratives overall ‘reported significant improvements in targeted clinical processes and patient outcomes’, the size of effects varied greatly between studies, reflecting both the varied ambitions of the collaboratives and the diversity of primary outcome measures used. Studies with high-quality (randomised) designs were less likely to report a positive outcome than studies with weaker designs, and the authors note risks of bias in several of the reported evaluations. Most of the studies included claimed to follow the template set out by the IHI’s Breakthrough Series approach, but how this was translated into practice was rarely specified.Reference Wells, Tamir and Gray52
4.2 How to Make Quality Improvement Collaboratives Work Better
While the literature continues to suffer from notable weaknesses, some evidence about the features of quality improvement collaboratives that appear to be associated with positive outcomes has nonetheless emerged.Reference Hulscher, Schouten and Grol25,Reference Øvretveit, Bate and Cleary26,Reference Kilo53 One of the most celebrated success stories for collaboration-based approaches is the Michigan Keystone project, which sought to reduce infections associated with central line catheters in intensive care units (ICUs).Reference Pronovost, Needham and Berenholtz54 It brought together clinicians from 108 ICUs across the state and provided them with training, periodic conference calls, coaching, and biannual statewide meetings. A before-and-after study of the intervention reported substantial reductions in infection rates.Reference Pronovost, Needham and Berenholtz54 A separate, retrospective analysis sought to shed light on the reasons for its success, identifying key mechanisms that appeared to be critical (Box 6).Reference Dixon-Woods, Bosk, Aveling, Goeschel and Pronovost55 It was also a prototype for the clinical communities approach described in Section 3.4.
Box 6 Mechanisms that explain the success of the Michigan Keystone project for reducing infections associated with central lines in ICUs
Generating the will for ICUs to take part in the initiative.
Creating a networked community.
Challenging the received wisdom that bloodstream infections are an inevitable risk of catheterisation, and recasting them instead as a social problem that is amenable to intervention.
Developing, sharing, testing, and refining various interventions that can be used at the sharp end of care, particularly interventions that precipitate change in social and interprofessional dynamics, such as goal-setting meetings and a checklist.
Using data effectively so participating teams can see where their efforts are having an impact, and benchmark their improvements against others.
Selectively harnessing ‘hard edges’ – more coercive features that complement the intrinsic motivation of participants by making judicious use of external expectations and pressures for improvement. These might include, for example, asking units that fail to provide data to withdraw from the programme, or explicitly ranking units to make clear which ones are falling short of the standards expected.
An intriguing postscript to the success of the Michigan Keystone project – and one that illustrates the work needed to get quality improvement collaboratives to work – was the rather different fate of a follow-up programme that sought to replicate its achievements in England. The Matching Michigan programme, modelled explicitly on the Michigan Keystone project, reported a disappointing outcome: it had no additional impact on infection rates over the reductions already in train.Reference Bion, Richardson and Hibbert56 A process evaluation found that many of the mechanisms that may have made the original collaborative a success in the USA were absent in England.Reference Dixon-Woods, Leslie, Tarrant and Bion57 In particular, the programme lacked many of the features necessary for collaboration-based approaches to succeed, in part because it was run by a government body, in part because of a widespread perception of a wider punitive policy environment, and in part because no real networked community emerged. Participants tended to view the programme not as a clinically led, peer-owned collaborative, but as another top-down, centrally driven initiative. These findings suggest that both the context for collaboration-based approaches, and the sophistication with which their principles are put into practice, have critical consequences for their effectiveness.
For further insight into how to make a collaborative work, Øvretveit et al. provide a helpful, if somewhat dated, contribution.Reference Øvretveit, Bate and Cleary26 They identify ten key challenges associated with collaboratives and offer advice on how best to overcome them (Box 7). Hulscher et al. also offer practical, evidence-informed advice on how best to make collaboratives work.Reference Hulscher, Schouten and Grol25
Box 7 How to get quality improvement collaboratives to work
Choose a sufficiently specific subject, one that is strategically important to participating organisations, and one where sufficient evidence-based interventions are available as a starting point for the collaborative’s work.
Ensure that teams are properly selected and prepared for the collaborative, so they know what their objective is and they have the capacity to benefit from participation. Internal team dynamics can be crucial to each team’s ability to contribute to and benefit from the collaborative.
Dedicate sufficient time in collaborative meetings ‘to facilitating learning by practice and to allowing teams to discuss how to apply ideas in the team’s home setting’. Ensuring participating teams have the opportunity for two-way dialogue is more important than trying to compress ‘too many didactic presentations into the meetings’.
Motivate and empower participating teams by enlisting credible experts, providing good evidence, highlighting the human cost of suboptimal practices, and offering practical examples of how other teams have translated principles of high-quality care into practice in real-life settings.
Ensure that teams have measurable and achievable targets for their work, including a balance between challenge and feasibility. Include mechanisms for feedback to the collaborative.
Plan for sustaining improvements beyond the course of the collaborative, which may mean considering aspects of care that are not within the immediate control of participating teams, and spreading learning to other units and organisations that did not participate.
4.3 Do Communities of Practice Work?
Because communities of practice are a rather looser intervention than quality improvement collaboratives, the challenge of producing an integrated, coherent, definitive evidence base about whether they work is even harder. Consistent with their focus on the sharing of knowledge to inform professional practice as an end in itself, their objectives are often diffuse, and only indirectly related to care outcomes; they may even defy measurement. Consequently, systematic reviews of the approachReference Li, Grimshaw and Nielsen58,Reference Ranmuthugala, Plumb and Cunningham59 have focused more on the question of what communities of practice look like and how they have been operationalised in the healthcare context, rather than on the evidence for their effectiveness.
In their systematic review of communities of practice in the business and healthcare sectors, Li et al.Reference Li, Grimshaw and Nielsen58 found that those convening and studying communities of practice mostly took Wenger et al.’s definition as their starting point (i.e. ‘groups of people who share a concern, a set of problems, or a passion about a topic, and who deepen their knowledge and expertise in this area by interacting on an ongoing basis’Reference Wenger, McDermott and Snyder38). In practice, however, they found that the form taken by the communities varied substantially, often deviating from the original principles in significant ways. Key characteristics that might be seen as prerequisites for calling a group a community of practice – ‘social interaction among members, knowledge sharing, knowledge creation, and identity building’ – were ‘not consistently present in all [communities of practice]’.Reference Li, Grimshaw and Nielsen58 The authors were unable to find any credible evidence for the effectiveness (or not) of communities of practice.
A subsequent review, by Ranmuthugala et al.,Reference Ranmuthugala, Plumb and Cunningham59 found a trend from descriptive towards evaluative literature over the two-decade period they covered. This review also noted that communities of practice tend to be one element of much wider change strategies, such that it was ‘difficult to differentiate the impact of the [community of practice] component of the intervention from the rest’.Reference Ranmuthugala, Plumb and Cunningham59 Three studies included in their review, including one randomised controlled trial, suggested that communities of practice were associated with improvements in certain outcomes. The trialReference Barwick, Peters and Boydell60 focused specifically on the uptake and implementation of an evidence-based standardised outcome measure for children’s mental health, suggesting that, in the right circumstances, communities of practice can be useful in achieving improvement aims.
Nevertheless, there is a sense from this literature that the community of practice is best treated as what it is: an open-ended, largely self-organising process led by members, who are working towards ends that they define and that are not fixed. This is quite different from an intervention in the narrower sense of the term, which is driven by specified objectives that relate to improvements in the process or outcomes of healthcare. Yet there is also a sense, in healthcare and elsewhere, that the idea of the community of practice is increasingly seen as a ‘knowledge-management intervention’: a key part of an organisation’s infrastructure that can help to aid the diffusion of information across units, professional groupings, and geographical boundaries, but which diverges even further from the idea of self-organisation and self-defined objectives.Reference Cox61
5 Critiques of Collaboration-Based Approaches
Collaboration-based approaches are widespread but have been subject to critique. One set of challenges is quite practical in character. It is easy to underestimate the level of operational, administrative, and infrastructural support necessary to achieve high-quality coordination of a collaborative effort, and the costs associated with collaborative interorganisational relationships may be significant but hard to resource.Reference Kirkpatrick62
A perhaps even greater problem is that these approaches are based on the fundamental assumption that those involved in them take their obligations seriously, and will cooperate in good faith to achieve the goals of the endeavour. But the peer-based networks on which collaborations are based often have limited means of correcting those who fail to live up to these expectations. Ostrom’s classic analysisReference Ostrom63 points towards the tensions between individual and collective interest in any situation where there is a ‘commons’ or shared resource (such as a collaborative, community of practice, or other network). Some form of oversight may therefore be a (regrettable) necessity, regardless of the arrangement for delivering or improving healthcare. But it can be difficult to achieve without reproducing the very hierarchical structures that collaboration-based approaches seek to bypass.
Exactly these challenges surfaced in a quality improvement collaborative in 2008–09, modelled explicitly on the Breakthrough Series approach. It aimed to improve the quality of stroke care in north-west England, as measured by key indicators in the English National Sentinel Audit of Stroke. A cluster-randomised controlled trial suggested that the collaborative was associated with modest improvements in relation to some of the process measures (compared with an ongoing positive trend occurring independently of the intervention, and possibly a contamination effect, which saw smaller improvements in the control hospitals too).Reference Power, Tyrrell and Rudd64 An accompanying process evaluation found that participating units contributed with varying degrees of enthusiasm to the collaborative, and identified factors that could stifle engagement and hinder progress.Reference Carter, Ozieranski, McNicol, Power and Dixon-Woods65 Notably, some of these were issues of the kind suggested by social scientific theory such as Ostrom’s.Reference Ostrom63 For example, Carter et al. identified the phenomenon of ‘social loafing’ (whereby people working together tended to exert less effort than when working individually), as well as ‘collaborative inertia’ (the challenge of initiating and coordinating action among a diffuse social group). They also found some evidence of a ‘free-rider’ effect, whereby ‘self-interested actors, acting rationally, may substitute their own goals for those of the group, so that collaboration is undermined by the self-interests of individuals as they pursue competitive rather than collaborative advantage’.Reference Carter, Ozieranski, McNicol, Power and Dixon-Woods65
Developments of collaboration-based approaches to improvement, such as clinical communities (see Section 3.4), have sought to learn and apply these lessons. By making use of hard edges and enforcing social norms – for example, by insisting on high-quality measurement and a degree of accountability – these latter approaches seek to reduce the risk that an overly idealised notion of humans’ cooperative instinct may produce collaborative failure. Nevertheless, the literature suggests that there will be limits to the extent to which collaborative forms can draw managerial pressures to their advantage, especially when the goals of collaboratives are low on the list of organisations’ priorities.Reference Stephens, Peden and Pearse66
Further challenges arise when collaboration-based approaches are superimposed on more hierarchical or market-based systems.Reference Kirkpatrick62 The example of managed clinical networks (see Section 3.2) shows how supposedly collaborative networks can retreat from their initial ambition of facilitating the sharing of knowledge across staff and organisations, and become instead appropriated as a tool for hierarchical imposition and acquiescence to performance targets.Reference Addicott, McGivern and Ferlie34
Some weaknesses of collaboration-based approaches are specific to the approach chosen. For instance, the tendency of some forms of quality improvement collaborative to focus on and reward rapid change can result in a wearying and inappropriate ‘sprint race’.Reference McLeod and Peck28 The episodic character of Breakthrough Series collaboratives, for example – existing only for a defined period while a problem is tackled – may risk inhibiting the development of the kinds of cooperative, network-based relationships that are most likely to produce enduring capability for improvement.Reference Wells, Tamir and Gray52,Reference Bate and Robert67 The short-term, intense focus on single issues may also divert focus from deeper, less tractable issues in improvement. Further, the available evidence suggests that the run charts favoured by Breakthrough Series collaboratives are not always of good quality,Reference Benn, Burnett and Parand68 and may not command the respect and credibility accorded to more robust registry-based initiatives. In this light, the enduring infrastructure of collaboratives, such as the Vermont Oxford Network and the Northern New England Cardiovascular Disease Study Group, may be a more useful model for long-lasting collaboration and sustainable change.
The community of practice approach is not without its challenges, either. Some argue that by thinking of communities of practice primarily as a solution to the challenge of organising and applying ephemeral, tacit knowledge, there is a risk of subordinating the concept to managerial interests. Rather than offering a means for professionals to hone their practice through interaction with their peers, the community of practice is at risk of becoming:
… a tool for management to manage ‘knowledge workers’ and experts. … The idea that a large organization should create pockets of collaboration to counteract its rationalizing, formalizing tendencies seems entirely sensible. … The ambiguity of whether this is genuine empowerment or the management involvement introduces a new form of normative control may be the key to why so many [communities of practice] fail.Reference Cox61
Even if communities of practice manage to evade managerial control, they face, like quality improvement collaboratives, challenges from a wider institutional field in which vertical command and lateral competition can marginalise the cooperative ethos.Reference Cox61 Though they are intended to be more-or-less self-sustaining and self-organising, and to require less administrative overhead, the organisation of work – including short-term contracts, geographically diffuse arrangements, and unstable project teams – makes it increasingly difficult for communities to emerge, organically or otherwise.Reference Roberts69 Their costs are difficult to estimate, and it is difficult to frame them in the cold, hard terms of intended outcomes, measurable change, and cost-effectiveness, making it hard to build business cases for their support.
6 Conclusions
Collaboration-based approaches offer much promise and are sometimes seen as offering a way of combining the benefits of bottom-up and top-down improvement. But, notwithstanding the aspirational, cooperative principles on which they are founded, they are not a panacea. Despite decades of research, the evidence base for collaboration remains insecure and contingent, hindered by the difficulties of establishing effectiveness and determining costs. While frustrating, this is perhaps not surprising. By their nature, complex approaches like collaborations are likely to work in different ways in different circumstances, and the fate and impact of such interventions lies at least as much in the hands of those leading them – and their enthusiasm, skill, judgement, charisma, tenacity, and sheer hard work – as in the design of their originators.Reference Dixon-Woods, Bosk, Aveling, Goeschel and Pronovost55
Despite the problems with the evidence base, important learning has emerged that will be valuable to those seeking to use a collaboration-based approach. Some of this learning involves providing the right impetus to help a collaboration to organise itself while avoiding undermining its ethos through excessive control. As we have discussed, some collaboration-based approaches arguably suffer because they rely too much on the commitment and goodwill of their members, but others perhaps risk stifling the benefits of cooperation by grafting managerial methods onto the collaboration. A would-be collaboration preoccupied with addressing narrow, managerially determined objectives may represent the worst of both worlds, by diminishing authority and clout over network members, and inhibiting opportunities for building trust, reciprocity, and space for innovation.
The evidence also suggests a need for precision in some things and flexibility in others. It is clearly important to identify the improvement objective, and to have some idea of how this might be achieved and how progress might be measured. It is much less clear that adherence to a particular template (e.g. the Breakthrough Series approach or any other) will secure improvement. There are also signs that excessive focus on achieving aims within a limited period may be counterproductive: it is challenging to normalise values and behaviours like trust and reciprocity quickly, and long-term sustainability may rest on the longevity of the membership and infrastructure of a collaboration. Recognition of the wider institutional context is key: external pressures may distract from, compete with, or distort the goals of the collaborative, and need to be anticipated from the outset. In other words, the network itself – not just the collaborative processes and behaviours that are built on it – should be a focus for consideration and investment. That can mean, for leaders, giving the latitude to deviate from organisational priorities so that members of a collaborative can find their own purpose, lest they be reduced to a rather clumsy and instrumental means of achieving top-down priorities or managing tacit knowledge.
The range of participants in a collaboration-based approach is also critical. For example, including administrative and managerial staff may be important not only in ensuring that the full range of relevant insights contributes to collective knowledge and action, but also in creating the right kinds of collective commitments and securing influence higher up in organisational hierarchies. It is also perhaps noteworthy that the involvement of patients and carers is documented in few of the published examples considered in this Element. As discussed in the Element on co-producing and co-designing,Reference Robert, Locock, Williams, Dixon-Woods, Brown and Marjanovic1 the participatory turn in thinking on improvement emphasises the importance of patients’ and carers’ perspectives to formulating interventions that result in improvements that matter to them.
Finally, health-economic evidence for collaboration-based approaches remains weak. Their impacts in some circumstancesReference Wells, Tamir and Gray52 do not necessarily translate into cost-effectiveness. The cost of collaborative events and of organisers’ and clinicians’ time can be high. The opportunity cost – the alternative uses to which healthcare systems might put their efforts, and their potential benefit – should also be considered.
All in all, and perhaps to be expected given the heterogeneity of both the forms they have taken and the functions they have served, the message for practitioners considering collaboration-based approaches is to see them as neither utopia nor dystopia. If they are to have a chance of success, it is crucial to find the difficult balance between defining aims, processes, and measures, and providing the space, time, and latitude to allow them to flourish.
