As a medical director I am routinely required to assess, grade and act on the results of serious adverse events that have occurred in hospital. Often these events have resulted from failures of care through lapses, oversights, errors or neglect. This is often accompanied by a clarion call for some form of disciplinary action and or restitution – usually most insistently from within the organisation rather than by those directly affected, either carers or the patients themselves.

Bad things happen in hospital all the time. Healthcare is the only industry where for a significant minority of users the outcome is death or injury, either expected or unexpected. The overwhelming priority in this situation for both the recipients and providers of the care is learning: learning the truth of events, learning if it was avoidable, learning how it might be avoided in the future, and sharing that learning so it might be avoided elsewhere.

Prerequisites for Organisational Learning

We have, as human beings, an innate gift for learning – it is built into our DNA and, whilst most active in our early years of life, never really leaves us. Individual learning is the most powerful lever of change in human societies, because people love to learn and change as a result. Teams and organisations are made up of people and yet team and organisational learning does not happen by chance as it does for individuals – team learning is an unnatural and deliberate act.

There are three prerequisites needed within organisations in order to promote learning from error and system failure. It is strangely rare to find them all reliably present in healthcare organisations.

  • A Learning Environment
  • A Team Based Learning Infrastructure
  • A Compelling Vision Delivered Through Leadership
  • I will expand on these three prerequisites, but first I want to explore why they are found rarely in our hospitals and healthcare organisations.

    Two Key Barriers to Organisational Learning in Hospitals

    Hospitals are busy places, this is a universal truth – not unique to the NHS. The work processes of nurses and doctors in hospitals rarely run smoothly – they are by their nature characterised by frequent interruptions, unexpected deviations and minor crises. In order to get the job done a large part of the work involves having to create on-the-hoof workarounds and solutions to problems – giving rise to the familiar sense of almost continuous ‘fire fighting’.
    20130120-132457.jpg
    We are actually incredibly successful at doing this, much of our individual innate learning capacity is consumed developing coping strategies for the chaotic environment we find ourselves in. The problem with this ‘first order problem solving’ for ‘low level failure’ is that the learning it generates is of value only to the individual nurse or doctor – they are simply adapting to the flawed environment they find themselves in – just to get the job done. In doing so they are condemning themselves and and their successors to having to learn the same lessons in perpetuity – this grinds you down and drives talent away from ‘the front line’. How do we break the cycle of low level failure that requires constant first order problem solving making every day work flow inefficient and time consuming? The first step is to recognise the problem and then acknowledge that low level failure, whilst common place, is neither inevitable nor acceptable. The next step is to then deliberately and collectively make the time to move first order problem solving into second order problem solving (of which more later).

    The second key barrier to organisational learning in hospitals is a deeper, more cultural one. This is to do with interpersonal attitudes and responses to error. The shameful truth is that the overwhelmingly pervasive culture is a blaming one that inhibits speaking up with questions, concerns and challenges that might otherwise have caught and corrected human error. Moreover there is a culture in medicine that does not encourage admissions of error. Both ourselves and others have high expectations of success in medicine – when we don’t meet those expectations we are as blaming of ourselves as we might expect others to be. What is interesting is that the direction of blame isn’t just top down – in fact top down blame only really materialises when the failures mount up to catastrophic levels. The vast majority of, and undoubtedly more corrosive, blame is that of our colleagues and peers. What is clear is that whilst blame remains the primary response to failure opportunities for learning will be lost and the quality of the lessons learnt will be poor. Overcoming this barrier is a true challenge of leadership at all levels of an organisation as it requires a change in culture – a clear and sustained statement and restatement of values, unwavering adherence to behaviours that follow from those values, even in the face of challenges from within and without the organisation.

    Leading Learning for Patient Safety

    So where should we start with creating a learning culture in our organisations? The answer has to be with leadership, because without leadership on this issue nothing else can follow. The type of leadership and skills required to lead learning, however, are not what are typically viewed as traditional leadership skills. The leadership model for leading learning differs from the traditional leadership model in several important ways:

  • Whilst a ‘burning platform’ undoubtedly exists, the future state can only be guessed at (in an educated way)
  • This makes it hard to articulate
  • The flaws in the current state are hard to spot – there is a deep seated culture of acceptance of low level failure
  • The way forward is not a clear plan with deadlines and critical paths but a process of experimentation, a gradual reduction of uncertainty and regular revision of interim goals and ultimate vision
  • The leadership task is primarily one of engagement and reduction of fear not a promotion of employee effort
  • The task will never be finished
  • If you have read my previous blogs you might guess that I believe these ‘New Model Leaders’ need to come from the rank and file of doctors, nurses and other healthcare professionals that don’t often put themselves forward for such a role.

    Second Order Problem Solving and A Team Based Learning Infrastructure

    Second order problem solving is about creating long term fixes for recurrent problems, it is about analysing root causes and putting in place solutions with ‘traction’, it is often about changing behaviours in ourselves that have consequences for others. There are several reasons why we don’t stop and take the time and effort required to convert first order to second order problem solving. First of all – it does take both time and effort – neither of which we have much left of after a day / week / month / years of fire fighting. Secondly the problems we need to solve are quite often not even perceived as problems, we have been compensating for so long it has just become part of the job – this is where our new model leader has to be insightful. Thirdly second order problem solving requires some quite specific skills such as root cause analysis, process mapping, and change modelling that are not commonly found in healthcare teams. Fourthly – we are quite proud of our first order problem solving, being a coper and thriver in a stressful front line job is associated with significant kudos, particularly in the hospital environment. Finally it does require us to meet as teams for a significant time on a regular basis – which we are astonishingly bad at doing – and when we do for those team meetings to be led in a way that promotes speaking up, learning from others, admissions of failure and a willingness to innovate (and therefore risk failure). This final requirement leads on to the the final pre-requisite for organisational learning – an environment of psychological safety – A Learning Environment

    Blame Free Culture Vs Accountability – A Balance that Creates ‘Psychological Safety’

    Our new model leaders have their work cut out – not only do they have to create time (in an already overloaded time table) to bring together teams (who are singularly reluctant to gather) to discuss both low level and high level failure (failures that may not even be recognised as such) and defend these notions against pressures to use the time ‘more productively’; but also resist the temptation and pressures from above, inside and out to apportion blame for every failure that comes to light. The prize is great if they achieve it – a learning environment in an organisation that continually improves both itself and the people that move through it, one that delivers both on the economic and quality front. A true value adding organisation.

    But – it can’t all be so idyllic surely? People do also make mistakes borne out of stupidity, brazen over confidence, ignorance, stubbornness, laziness, jealousy and – yes – even malice. There is a level of human behaviour for which we all need to be held account. There is also a performance imperative, we all have to be helped to raise our game. Where is the place for accountability in a blame free culture? The diagram below will perhaps help you decide…

    20130120-213610.jpg
    This is the essential difference between ‘blame free’ and ‘psychologically safe’ for the latter comes not just from creating an environment where people feel able to speak up and admit failure but also feel assured that when boundaries are truly crossed that individuals will be held to account. This is the real test of leadership – knowing and communicating expectations and boundaries as well.

    Blameworthy Acts – the Boundaries of a Blame Free Culture

    Where do you draw the boundaries? There are no text books, there are no rules – there is intuition and there are inspirational leaders we can follow. Here is my starter for ten of blameworthy acts:

  • Reckless behaviour
  • Disruptive behaviour
  • Working significantly outside your capability
  • Disrespectful behaviour
  • Knowingly violating standards
  • Failure to learn over time
  • Failure to work as a team
  • Covering up
  • No doubt there are more. Clear boundaries around a learning zone create an environment in which organisations can thrive and patients can feel and be safe.

    I have to acknowledge the source of the ideas for this article. Amy C Edmonson – a truly inspirational teacher at HBS who not only articulates this message with conviction but backs it up with the irrefutable results of research both in healthcare and other settings.

    There is a solution to all the problems in healthcare – it is a simple one, it has a successful track record in many high risk industries and it is one that is acceptable to all stakeholders in the health transaction – Professionals, Patients, Payers, Politicians and Managers. It also saves money – lots of it…

    The solution has been called different things in different industries, it has been adopted in various styles at different points in history by these different industries – but is essentially the same thing. Health is probably the last high risk industry to adopt this solution and is doing so rather slowly, grudgingly if at all – for one simple reason: The harm that healthcare causes does not affect either the payers or the providers of the service.

    The airline industry was an early adopter – because it discovered pretty quickly that not adopting it would be fatal to themselves and their customers. There was also pretty effective self selection of non-adopters as heroic, buccaneering individuals and organisations literally crashed and burned. The oil and gas industry followed somewhat later when they discovered that adopting it made them money – lots and lots of it – with safety being a welcome side effect.

    The solution has created a world where it is safer to fly than it is to drive to the airport. Where more people are killed by petrol in their own garages than in the entire global petrochemical processing industry. Where we enjoy astonishing improvements in quality, safety and utility of the products we consume at either the same or diminishing cost (think of the mobile phone you use now compared to ten years ago).

    The solution is a culture, a state of mind and a way of doing things – it is a committed, system wide and systematic approach to reliability.

    The commonest argument used against the proposal to adopt a reliable approach to delivering healthcare goes along the lines of – ‘Patients are not widgets’; ‘Jumbo jets are more reliable than patients’; ‘There is so much uncertainty in medicine’; ‘This constrains my freedom of practice’ etc. Blaming patients for unreliable healthcare is, however, a highly disingenuous argument. Patients are unreliable, they do present us with enormous problems of variance and deviance from the expected, medicine is difficult – but that is their nature, that is their right. Putting them into an unreliable healthcare system produces variance on variance – which, I have said before, is the definition of chaos. Unreliable healthcare results in unsafe medicine, uncertain and poor outcomes, errors that are destined to be repeated (like history) all of which, not withstanding the human misery, costs. It has been estimated that nearly half of all health care costs are related to failures in the delivery of care.

    What is Reliable Healthcare Delivery?

    The trite (and not very helpful) answer to this question is the familiar ‘Doing the right thing and doing things right’. This particular definition ignores the rather large zone of uncertainty that exists between what we know is the right thing and what we know is the wrong thing. If we were to pause and reflect on the state of medical knowledge and draw a diagram representing each of these three zones – what we know is right (white), what we know is wrong (black), where there is room for argument (grey) – how big would we draw each of the zones? What strategies would a reliable healthcare delivery system adopt in the three different knowledge zones?

    20120910-221331.jpg

    The White Zone – Doing the right thing the right way

    The truth of the matter is we have a huge amount of medical knowledge – there are very many areas of medicine where we know what the right thing to do is and how best to do it. The medical knowledge base is vast and increasing exponentially (see graph below) and there are swathes of medicine where the important unanswered question is not ‘What is the right thing to do?’ but ‘Why (IGN) are we not doing it?’. One of the main barriers to deploying medical knowledge appears to be the shear volume of new information – over 1 million original medical papers were published in 2010 alone. However we have allies to help us – there are expert groups, royal colleges, specialist societies, NICE, Map of Medicine, Bandolier, national and international consensus bodies who are systematically collecting, sifting and grading the evidence for us and telling us what we should do.

    20120910-215345.jpg

    Yet as McGlynn et al. discovered we still don’t do it nearly 50% of the time (see table below). Why? There are healthcare organisations that do take a systematic approach to doing the right thing – Intermountain Health in Utah USA is one of the most outstanding high performing healthcare organisations in the world. Their outcomes for most common medical and surgical diagnoses are way above their peers – their mortality from sepsis is 9.3% compared to a US average of 25% – 40%. They are one of the few organisations in the US that makes a return on Medicare and Medicaid reimbursements. They invented the care process model – of which more later.

     

    There will be doctors reading this (most of them) that are convinced that they are practicing to the highest and most up to date standards, and able account for that standard of care they provide. Yet the outcome from their institutions will come nowhere near those of Intermountain. Whilst they may account for their own practice they will undoubtedly be a little more taciturn on their colleague’s practice, and perhaps a little more vocal about what they perceive the standard of care provided to patients before they arrived in their care and maybe after they left as well. And there is the rub – for to deliver outstanding outcomes we have to do the right thing every step of the way on the patient’s journey – for every patient.

    A good outcome is the aggregated marginal gains of multiple inputs by many professionals. Reliable healthcare is a team sport and as Atul Gawande put it in his tour-de-force ‘The Checklist Manifesto’ we are still practicing the medicine of the heroic individual – we are only just emerging from the buccaneering age of medicine, equivalent in the airline industry of when aircraft routinely fell out of the sky. Unlike buccaneering pilots though doctors don’t die with their mistakes.

    The problem with doing the right thing is that it is rather mundane. It involves being told what to do, it involves following checklists, care bundles, protocols and pathways. It also involves agreeing with your team ‘how we are going to do things here’; that inevitably involves negotiation and compromise, going along with the consensus because doing so is for the greater good. Heroic doctors are not very good at doing those sorts of things. It also takes a lot of collaborative effort to get there.

    There is still plenty of scope for the heroic doctor though. To paraphrase Atul Gawande again ‘Checklists are there to get the 80% of mundane stuff right so that the mind is freed to do the heroic 20%’. It is vital to get the 80% right – otherwise our heroics become expensive futilities.

    The Black Zone – when it goes wrong

    Understanding and managing medical error is a huge topic in of itself – which I will undoubtedly expand in future posts. I am though in a hurry (for a change) to move on to the bit I am interested today which is the grey zone. Suffice to say for now that you cannot be a highly reliable healthcare organisation if you do not manage medical error well.

    The Grey Zone – Learning from uncertainty

    This is where it starts getting very interesting. In our daily practice as doctors our patients constantly present us with dilemmas. Situations where doing the right thing seems to be the wrong thing, or where doing the right thing for one problem is definitely the wrong thing for another. As our patients get older and compound multiple pathologies these dilemmas increase all the time. Each time we are presented with these situations it feels as though we are solving the problem for the first time over and again for each patient – we are faced with the huge and overwhelming variance in presentation and response to treatment.

    The traditional medical model for dealing with these situations is the ‘iterative care process’ underpinned by the ‘experienced clinician’. This care process involves a combination of medical detective work (history and examination), Diagnostic hypothesis (differential diagnosis), Diagnostic tests or a ‘Diagnostic Therapeutic Trial’ (we’ll give antibiotics and see if they get better…). Experience helps by being able to ask the right questions, come up with a feasible and manageable list of diagnostic hypotheses and also design a diagnostic prescription that does the minimum to confirm or refute the hypothesis. Patients will often go through several cycles of this process (either because it doesn’t solve the problem or because the patient has moved to a different team) – with escalating intensity and invasiveness of investigation – until either a diagnosis is made and correct treatment started or the progress of the condition outpaces the process and the patient succumbs (or they get better despite us).

    There are several reasons why this model is problematic and fails to deliver reliable care. The first is that the operating model of the modern hospital (the process by which patients move through the organisation) is not aligned to the iterative care process. The second is we are not very good at it any more – we don’t have enough experienced clinicians to see and review patients progress through the care process in a timely or frequent enough way. Thirdly it is slow, expensive and unreliable. Finally it does not deliver learning at anything other than an individual level – hence the very real sense in which we feel we are re-solving the same problems day-in day-out without seeming to make much progress.

    The complexity of modern medicine and modern patients, the dissolution of traditional medical teams and their replacement by the transitory, multi-professional, socially complex, modern alternatives – means we need a new model for delivering care.

    This medical model needs to achieve several things:
    1) Reliable delivery of care that we know is right that does not depend on the location of the patient, or the presence or absence of a particular professional.
    2) Keep up-to-date with the ever expanding body of medical knowledge
    3) Generate ‘Team Learning’ from variance in presentation and response
    4) Generate ‘Team Learning’ from medical errors
    5) Use that learning to modify and adapt the care process

    The ‘Care Process Model’ invented by Intermountain achieves all of these things. On first glance it appears to be a set of protocols – and many subsequent implementations have deployed it as such. However seeing it as such is missing the point – the content of the protocol is much less important than the process by which it comes about and the way that it is used.

    The diagram below shows the essence of the care process model development and more to the point continuous improvement through organisational learning.

    20120910-231035.jpg

    The essential components are:
    1) An expert team that crystallise the current state of medical knowledge into detailed guidance
    2) Clinical senate that simplify and standardise to a deployable protocol across the whole system
    3) An operating system that reliably delivers elements of the CPM at all points of the pathway – the protocol is the record
    4) A reporting and monitoring system of deviance from the pathway – an expected deviance of 20% is built in – but all deviance is reported and analysed including medical error
    5) Outcomes are monitored
    6) Information is fed back to the clinical senate that adjust the CPM

    You will see that this generates organisational learning – the system gets smarter – and that it does so using three distinct knowledge types – The global medical knowledge base generated by original research, knowledge of its own patient group through analysis of unexpected response and outcome, knowledge of itself through analysis of medical error and non-compliance.

    In my next post I will discuss the pre-requisites in culture, structure and process that are required to create organisational learning and how rare they are in the NHS.
