This recent tweet represents a significant milestone.  It formally recognises and celebrates in public the impact that developing health care systems engineering (HCSE) capability has had on the culture of the organisation.

What is also important is that the HCSE training was not sought and funded by the Trust, it was discovered by chance and funded by their commissioners, the local clinical commissioning group (CCG).


The story starts back in the autumn of 2017 and, by chance, I was chatting with Rob, a friend-of-a-friend, about work. As you do. It turned out that Rob was the CCG Lead for Unscheduled Care and I was describing how HCSE can be applied in any part of any health care system; primary care, secondary care, scheduled, unscheduled, clinical, operational or whatever.  They are all parts of the same system and the techniques and tools of improvement-by-design are generic.  And I described lots of real examples of doing just that and the sustained improvements that had followed.

So he asked “If you were to apply this approach to unscheduled care in a large acute trust how would you do it?“.  My immediate reply was “I would start by training the front line teams in the HCSE Level 1 stuff, and the first step is to raise awareness of what is possible.  We do that by demonstrating it in practice because you have to see it and experience it to believe it.

And so that is what we did.

The CCG commissioned a one-year HCSE Level 1 programme for four teams at University Hospitals of North Midlands (UHNM) and we started in January 2018 with some One Day Flow Workshops.

The intended emotional effect of a Flow Workshop is surprise and delight.  The challenge for the day is to start with a simulated, but very realistic, one-stop outpatient clinic which is chaotic and stressful for everyone.  And with no prior training the delegates transform it into a calm and enjoyable experience using the HCSE approach.  It is called emergent learning.  We have run dozens of these workshops and it has never failed.

After directly experiencing HCSE working in practice the teams that stepped up to the challenge were from ED, Transformation, Ambulatory Emergency Care and Outpatients.


The key to growing HCSE capability is to assemble small teams, called micro-system design teams (MSDTs) and to focus on causes that fall inside their circle of control.

The MSDT sessions need to be regular, short, and facilitated by an experienced HCSE who has seen it, done it and can teach it.

In UHNM, the Transformation team divided themselves between the front-line teams and they learned HCSE together.  Here’s a picture of the ED team … left to right we have Alex, Mark and Julie (ED consultants) then Steve and Janina (Transformation).  The essential tools are a big table, paper, pens, notebooks, coffee and a laptop/projector.

The purpose of each session is empirical learning-by-doing i.e. using a real improvement challenge to learn and practice the method so that before the end of the programme the team can confidently “fly” solo.

That is the key to continued growth and sustained improvement.  The HCSE capability needs to become embedded.

It is good fun and immensely rewarding to see the “ah ha” moments and improvements happen as the needle on the emotometer moves from “Can’t Do” to “Can Do”.

Metamorphosis is re-arranging what you already have in a way that works better.


The tweet is objective evidence that demonstrates the HCSE programme delivers as designed.  It is fit-for-purpose.  It is called validation.

The other objective evidence of effectiveness comes from the learning-by-doing projects themselves.  And for an individual to gain a coveted HCSE Level 1 Certificate of Competency requires writing up to a publishable quality and sharing the story. Warts-and-all.

And what started this was the CCG who had the strategic vision, looked outside themselves for innovative approaches, and demonstrated the courage to take a risk.

Commissioned Improvement.

One of the big hurdles in health care improvement is that most of the low hanging fruit have been harvested.

These are the small improvement projects that can be done quickly because as soon as the issue is made visible to the stakeholders the cause is obvious and the solution is too.

This is where kaizen works well.

The problem is that many health care issues are rather more difficult because the process that needs improving is complicated (i.e. it has lots of interacting parts) and usually exhibits rather complex behaviour (e.g. chaotic).

One good example of this is a one stop multidisciplinary clinic.

These are widely used in healthcare and for good reason.  It is better for a patient with a complex illness, such as diabetes, to be able to access whatever specialist assessment and advice they need when they need it … i.e. in an outpatient clinic.

The multi-disciplinary team (MDT) is more effective and efficient when it can problem-solve collaboratively.

The problem is that the scheduling design of a one stop clinic is rather trickier than a traditional simple-but-slow-and-sequential new-review-refer design.

A one stop clinic that has not been well-designed feels chaotic and stressful for both staff and patients and usually exhibits the paradoxical behaviour of waiting patients and waiting staff.


So what do we need to do?

We need to map and measure the process and diagnose the root cause of the chaos, and then treat it.  A quick kaizen exercise should do the trick. Yes?

But how do we map and measure the chaotic behaviour of lots of specialists buzzing around like blue-***** flies trying to fix the emergent clinical and operational problems on the hoof?  This is not the linear, deterministic, predictable, standardised machine-dominated production line environment where kaizen evolved.

One approach might be to get the staff to audit what they are doing as they do it. But that adds extra work, usually makes the chaos worse, fuels frustration and results in a very patchy set of data.

Another approach is to employ a small army of observers who record what happens, as it happens.  This is possible and it works, but to be able to do this well requires a lot of experience of the process being observed.  And even if that is achieved the next barrier is the onerous task of transcribing and analysing the ocean of harvested data.  And then the challenge of feeding back the results much later … i.e. when the sands have shifted.


So we need a different approach … one that is able to capture the fine detail of a complex process in real-time, with minimal impact on the process itself, and that can process and present the wealth of data in a visual easy-to-assess format, and in real-time too.

This is a really tough design challenge …
… and it has just been solved.

Here are two recent case studies that describe how it was done using a robust systems engineering method.

Abstract

Abstract

On Thursday we had a very enjoyable and educational day.  I say “we” because there were eleven of us learning together.

There was Declan, Chris, Lesley, Imran, Phil, Pete, Mike, Kate, Samar and Ellen and me (behind the camera).  Some are holding their long-overdue HCSE Level-1 Certificates and Badges that were awarded just before the photo was taken.

The theme for the day was System Dynamics which is a tried-and-tested approach for developing a deep understanding of how a complex adaptive system (CAS) actually works.  A health care system is a complex adaptive system.

The originator of system dynamics is Jay Wright Forrester who developed it around the end of WW2 (i.e. about 80 years ago) and who later moved to MIT.  Peter Senge, author of The Fifth Discipline was part of the same group as was Donella Meadows who wrote Limits to Growth.  Their dream was much bigger – global health – i.e. the whole planet not just the human passengers!  It is still a hot topic [pun intended].


The purpose of the day was to introduce the team of apprentice health care system engineers (HCSEs) to the principles of system dynamics and to some of its amazing visualisation and prediction techniques and tools.

The tangible output we wanted was an Excel-based simulation model that we could use to solve a notoriously persistent health care service management problem …

How to plan the number of new and review appointment slots needed to deliver a safe, efficient, effective and affordable chronic disease service?

So, with our purpose in mind, the problem clearly stated, and a blank design canvas we got stuck in; and we used the HCSE improvement-by-design framework that everyone was already familiar with.

We made lots of progress, learned lots of cool stuff, and had lots of fun.

We didn’t quite get to the final product but that was OK because it was a very tough design assignment.  We got 80% of the way there though which is pretty good in one day from a standing start.  The last 20% can now be done by the HCSEs themselves.

We were all exhausted at the end.  We had worked hard.  It was a good day.


And I am already looking forward to the next HCSE Masterclass that will be in about six weeks time.  This one will address another chronic, endemic, systemic health care system “disease” called carveoutosis multiforme fulminans.

This week saw the publication of a landmark paper – one that will bring hope to many.  A paper that describes the first step of a path forward out of the mess that healthcare seems to be in.  A rational, sensible, practical, learnable and enjoyable path.


This week I also came across an idea that triggered an “ah ha” for me.  The idea is that the most rapid learning happens when we are making mistakes about half of the time.

And when I say ‘making a mistake’ I mean not achieving what we predicted we would achieve because that implies that our understanding of the world is incomplete.  In other words, when the world does not behave as we expect, we have an opportunity to learn and to improve our ability to make more reliable predictions.

And that ability is called wisdom.


When we get what we expect about half the time, and do not get what we expect about the other half of the time, then we have the maximum amount of information that we can use to compare and find the differences.

Was it what we did? Was it what we did not do? What are the acts and errors of commission and omission? What can we learn from those? What might we do differently next time? What would we expect to happen if we do?


And to explore this terrain we need to see the world as it is … warts and all … and that is the subject of the landmark paper that was published this week.


The context of the paper is improvement of cancer service delivery, and specifically of reducing waiting time from referral to first appointment.  This waiting is a time of extreme anxiety for patients who have suspected cancer.

It is important to remember that most people with suspected cancer do not have it, so most of the work of an urgent suspected cancer (USC) clinic is to reassure and to relieve the fear that the spectre of cancer creates.

So, the sooner that reassurance can happen the better, and for the unlucky minority who are diagnosed with cancer, the sooner they can move on to treatment the better.

The more important paragraph in the abstract is the second one … which states that seeing the system behaviour as it is, warts-and-all,  in near-real-time, allows us to learn to make better decisions of what to do to achieve our intended outcomes. Wiser decisions.

And the reason this is the more important paragraph is because if we can do that for an urgent suspected cancer pathway then we can do that for any pathway.


The paper re-tells the first chapter of an emerging story of hope.  A story of how an innovative and forward-thinking organisation is investing in building embedded capability in health care systems engineering (HCSE), and is now delivering a growing dividend.  Much bigger than the investment on every dimension … better safety, faster delivery, higher quality and more affordability. Win-win-win-win.

The only losers are the “warts” – the naysayers and the cynics who claim it is impossible, or too “wicked”, or too difficult, or too expensive.

Innovative reality trumps cynical rhetoric … and the full abstract and paper can be accessed here.

So, well done to Chris Jones and the whole team in ABMU.

And thank you for keeping the candle of hope alight in these dark, stormy and uncertain times for the NHS.

This week, it was my great pleasure to award the first Health Care Systems Engineering (HCSE) Level 2 Medal to Dr Kate Silvester, MBA, FRCOphth.

Kate is internationally recognised as an expert in health care improvement and over more than two decades has championed the adoption of improvement methods such as Lean and Quality Improvement in her national roles in the Modernisation Agency and then the NHS Institute for Innovation and Improvement.

Kate originally trained as a doctor and then left the NHS to learn manufacturing systems engineering with Lucas and Airbus.  Kate then brought these very valuable skills back with her into the NHS when she joined the Cancer Services Collaborative.

Kate is co-founder of the Journal of Improvement Science and over the last five years has been highly influential in the development of the Health Care Systems Engineering Programme – the first of its kind in the world that is designed by clinicians for clinicians.

The HCSE Programme is built on the pragmatic See One-Do Some-Teach Many principle of developing competence and confidence through being trained and coached by a more experienced practitioner while doing projects of increasing complexity and training and coaching others who are less experienced.

Competence is based on evidence-of-effectiveness, and Kate has achieved HCSE Level 2 by demonstrating that she can do HCSE and that she can teach and coach others how to do HCSE as well.

To illustrate, here is a recent FHJ paper that Kate has authored which illustrates the HCSE principles applied in practice in a real hospital.  This work was done as part of the Health Foundation’s Flow, Cost and Quality project that Kate led and recent evidence proves that the improvements have sustained and spread.  South Warwickshire NHS Foundation Trust is now one of the top-performing Trusts in the NHS.

More recently, Kate has trained and coached new practitioners in Exeter and North Devon who have delivered improvements and earned their HCSE 1 wings.

Congratulations Kate!

One of the most frequent niggles that I hear from patients is the difficultly they have getting an appointment with their general practitioner.  I too have personal experience of the distress caused by the ubiquitous “Phone at 8AM for an Appointment” policy, so in June 2018 when I was approached to help a group of local practices redesign their appointment booking system I said “Yes, please!


What has emerged is a fascinating, enjoyable and rewarding journey of co-evolution of learning and co-production of an improved design.  The multi-skilled design team (MDT) we pulled together included general practitioners, receptionists and practice managers and my job was to show them how to use the health care systems engineering (HCSE) framework to diagnose, design, decide and deliver what they wanted: A safe, calm, efficient, high quality, value-4-money appointment booking service for their combined list of 50,000 patients.


This week they reached the start of the ‘decide and deliver‘ phase.  We have established the diagnosis of why the current booking system is not delivering what we all want (i.e. patients and practices), and we have assembled and verified the essential elements of an improved design.

And the most important outcome for me is that the Primary Care MDT now feel confident and capable to decide what and how to deliver it themselves.   That is what I call embedded capability and achieving it is always an emotional roller coaster ride that we call The Nerve Curve.

What we are dealing with here is called a complex adaptive system (CAS) which has two main components: Processes and People.  Both are complicated and behave in complex ways.  Both will adapt and co-evolve over time.  The processes are the result of the policies that the people produce.  The policies are the result of the experiences that the people have and the explanations that they create to make intuitive sense of them.

But, complex systems often behave in counter-intuitive ways, so our intuition can actually lead us to make unwise decisions that unintentionally perpetuate the problem we are trying to solve.  The name given to this is a wicked problem.

A health care systems engineer needs to be able to demonstrate where these hidden intuitive traps lurk, and to explain what causes them and how to avoid them.  That is the reason the diagnosis and design phase is always a bit of a bumpy ride – emotionally – our Inner Chimp does not like to be challenged!  We all resist change.  Fear of the unknown is hard-wired into us by millions of years of evolution.

But we know when we are making progress because the “ah ha” moments signal a slight shift of perception and a sudden new clarity of insight.  The cognitive fog clears a bit and a some more of the unfamiliar terrain ahead comes into view.  We are learning.

The Primary Care MDT have experienced many of these penny-drop moments over the last six months and unfortunately there is not space here to describe them all, but I can share one pivotal example.


A common symptom of a poorly designed process is a chronically chaotic queue.

[NB. In medicine the term chronic means “long standing”.  The opposite term is acute which means “recent onset”].

Many assume, intuitively, that the cause of a chronically chaotic queue is lack of capacity; hence the incessant calls for ‘more capacity’.  And it appears that we have learned this reflex response by observing the effect of adding capacity – which is that the queue and chaos abate (for a while).  So that proves that lack of capacity was the cause. Yes?

Well actually it doesn’t.  Proving causality requires a bit more work.  And to illustrate this “temporal association does not prove causality trap” I invite you to consider this scenario.

I have a headache => I take a paracetamol => my headache goes away => so the cause of my headache was lack of paracetamol. Yes?

Errr .. No!

There are many contributory causes of chronically chaotic queues and lack of capacity is not one of them because the queue is chronic.  What actually happens is that something else triggers the onset of chaos which then consumes the very resource we require to avoid the chaos.  And once we slip into this trap we cannot escape!  The chaos-perpretuating behaviour we observe is called fire-fighting and the necessary resource it consumes is called resilience.


Six months ago, the Primary Care MDT believed that the cause of their chronic appointment booking chaos was a mismatch between demand and capacity – i.e. too much patient demand for the appointment capacity available.  So, there was a very reasonable resistance to the idea of making the appointment booking process easier for patients – they justifiably feared being overwhelmed by a tsunami of unmet need!

Six months on, the Primary Care MDT understand what actually causes chronic queues and that awareness has been achieved by a step-by-step process of explanation and experimentation in the relative safety of the weekly design sessions.

We played simulation games – lots of them.

One particularly memorable “Ah Ha!” moment happened when we played the Carveout Game which is done using dice, tiddly-winks, paper and coloured-pens.  No computers.  No statistics.  No queue theory gobbledygook.  No smoke-and-mirrors.  No magic.

What the Carveout Game demonstrates, practically and visually, is that an easy way to trigger the transition from calm-efficiency to chaotic-ineffectiveness is … to impose a carveout policy on a system that has been designed to achieve optimum efficiency by using averages.  Boom!  We slip on the twin banana skins of the Flaw-of-Averages and Sub-Optimisation, slide off the performance cliff, and career down the rocky slope of Chronic Chaos into the Depths of Despair – from which we cannot then escape.

This visual demonstration was a cognitive turning point for the MDT.  They now believed that there is a rational science to improvement and from there we were on the step-by-step climb to building the necessary embedded capability.


It now felt like the team were pulling what they needed to know.  I was no longer pushing.  We had flipped from push-to-pull.  That is called the tipping point.

And that is how health care systems engineering (HCSE) works.


Health care is a complex adaptive system, and what a health care systems engineer actually “designs” is a context-sensitive  incubator that nurtures the seeds of innovation that already exist in the system and encourages them to germinate, grow and become strong enough to establish themselves.

That is called “embedded improvement-by-design capability“.

And each incubator need to be different – because each system is different.  One-solution-fits-all-problems does not work here just as it does not in medicine.  Each patient is both similar and unique.


Just as in medicine, first we need to diagnose the actual cause;  second we need to design some effective solutions; third we need to decide which design to implement and fourth we need to deliver it.

But the how-to-do-it feels a bit counter-intuitive, and if it were not we would already be doing it. But the good news is that anyone can learn how to do HCSE.
