Defeating General von Clausewitz

Even though he’s been dead for over a century and a half, Prussian military General Carl von Clausewitz still enjoys a well deserved reputation as one of history’s most important military strategic thinkers.   His overall premise was crystallized in his theories of “the fog of war” meaning that 18th and 19th century battles were basically a mass of confusion and randomness uncontrolled by battle plans, generals and military discipline.  Although he advocated planning for battles he lamented that “no battle plan survives its first encounter with the enemy”.  Meaning when the swords fell, the best laid plans of the generals fell with them.

The modern era is really not a lot different.  General Dwight D. Eisenhower, who planned and executed Operation Overlord, the most massively complex movement of men and materiáls in history, agreed with our Prussian friend.  He said “in preparing for battle I have always found that plans quickly become useless, but planning is indispensable.”  Obviously planning for battles and planning complex surgical procedures anticipate polar opposite outcomes.  But battle plans and operative plans have similarities and we can learn from these generals to plan our surgery with an expectation that things can and usually do change.  Both generals saw battles as complex interactions of multiple moving pieces; similar to the way we view a complex surgical procedure in the operating room.  There are always imponderable events and twists and turns that might not mesh with our previous experiences that can rarely be accurately scripted in advance.

So then what does this have to do with patient safety and how can we learn from this as practitioners of the high reliability mindsetThe take-away message for us in healthcare is that we have to understand the value of plans and make careful and complete plans but not depend on things going exactly according to plans in order to assure safe outcomes.  We also can never accept an excuse like “things just haven’t gone as I planned” as a reason for a bad outcome.   It is critical to make plans that will account for that “fog of war” and anticipate every possible problem, additionally imagining new ways that things can go wrong and plan for that.  We need to thoroughly brief and communicate all these plans with the team but still always be nimble and anticipate things will go wrong.

If we drill down into von Clausewitz’ theories a little more we see that he understood and stressed how opposite factors interact, especially how sudden and unexpected developments unfolding beneath the “fog of war” called for rapid and correct decisions by alert commanders.  Planning in advance and getting enough things ready for contingency efforts if, NO WHEN, the unexpected occurs, gives us more mental bandwidth to process data and information related to any new twists and turns.  This makes is more likely that we will react correctly with urgent accurate decisions even in time-compressed situations to assure good outcomes in emergencies.

Belly Aches and Other Distractions

In the last blog post I talked about distractions in the cockpit and the operating room.  Let’s follow up on that and see how distractions can have a potentially negative impact the entire team around us.  You might be OK with the loud music but other critical team members are getting distracted and that impacts the final outcome.  My kids and I used to play a driving game to see who could be the first to spot the driver of another car on their cell.  Eventually there were so many offenders, we changed the game  to spot those drivers NOT on their phone.  After that became pretty rare we then tried to spot the cars driven by talkers from a distance without looking in the window.  One kid would point out the car and then the other would look at the driver to check.

My son got pretty good at this– he could just “tell” by watching the car.  He had developed an ability to spot the markers of distracted driving.  One giveaway was going too slow (regardless of how smart you are you just can’t do two complex tasks at the same time without performance degrading on both).  Also he said the cars drifted across the lanes – sometimes into on-coming traffic until some honked. He said a real give-way was when they missed traffic signs and traffic lights and that they were just “bad drivers”.

He was right, and this has become such a problem that the NTSB has issued a recent recommendation to adopt federal laws banning use of cell phones while driving  Their statistics indicate that there is one traffic accident every 10 seconds of every day based on distracted driving – about 8,000 a day.  There were 33,788 highway fatalities last year and the use of a cell phone increases the risk of a fatal crash four-fold.  Sending text messages while driving increases the risk of a crash 23-fold!  Talking on a cell phone – even hands free – reduces drivers’ cognitive capabilities by 40% according to the Carnegie Mellon’s Center for Cognitive Brain Imaging giving the driver a reaction time equal to a blood alcohol level of 0.08 – which is legally drunk.   The human brain is not neurologically capable of as much “multitasking” as we believe and making an error by getting distracted from a critical task is a universal result of overloading our internal hard drives.  Distractions are important Error Producing Conditions.

So let’s play another game and call all the drivers on the road around you your “driving team”.  Do you really want these distracted players on your team?  Not only are they not paying attention but equally important is you can’t count on them to follow the rules of the road.  You also can’t predict their behavior which is a critical element of high reliability team skills.  But perhaps the most important point is that they are not prepared to act correctly in an emergency since their minds are somewhere else.  What if this was your operating room team?  Something can and at some point will go wrong.

So, back in the OR the music is on and everything is rocking.  The patient is a middle aged guy with his abdomen open having a colon tumor removed.  He did OK after the procedure and went home but kept complaining of a belly ache.  Finally an X-ray was taken (yes it’s real but no names, dates or places please).  The X-ray showed a 13-inch long, two-inch wide surgical retractor, known as a “ribbon retractor”, a stainless steel retractor resembling a metal ruler was inside the patient.  Come on, how can you leave something over a foot long inside someone and not know it?

According to the findings of the hospital investigation and public court documents (yes the surgeons got sued) it had been “accidentally left in the patient after it somehow slipped from the hands of a distracted doctor during the procedure.”  It had to be surgically removed by another team of surgeons – who hopefully were paying full attention this time.

Distracted performance is a real matter of patient safety.  As good team leaders we need to enforce an environment where everyone at every position on the team is fully engaged during those critical times of the procedure.  Things that we might not find distracting can be distracting to others and degrade the performance of the entire team.  Be on guard during times when events become distracting such as phones ringing and shift and personnel changes.  Maintain your own and team “situational awareness” by continuously assessing the circumstances and testing this by communicating with your team. We can learn from others’ errors so as not to make them ourselves.  This incident isn’t from a long-gone era, it was only settled a couple of years ago.  We can and must do better at the simple task of paying attention and maintaining the “sterile environment” that is necessary for maximum performance from everyone on the team.
