Escape Fire and high reliability

I have bene rereading two books recently, Managing the Unexpected, (a fantastic read) and Berwicks Escape Fire. Berwick spoke about the Mann gulch fire disaster in Montana, about which Weick has written. Although at first pass, one wonders what lessons a forest fire in Montana has to delivering safe care in health, there are many deep lessons to be learned. This is a paper well worth reading. A few examples.

To be wise is not to know particular facts but to know without excessive confidence or excessive cautiousness. Wisdom is thus not a belief, a value, a set of facts, a corpus of knowledge or information in some specialized area, or a set of special abilities or skills. Wisdom is an attitude taken by persons toward the beliefs, values, knowledge, information, abilities, and skills that are held, a tendency to doubt that these are necessarily true or valid and to doubt that they are an exhaustive set of those things that could be known.
In a fluid world, wise people know that they don't fully understand what is happening right now, because they have never seen precisely this event before. Extreme confidence and extreme caution both can destroy what organizations most need in changing times, namely, curiosity, openness, and complex sensing. The overconfident shun curiosity because they feel they know most of what there is to know. The overcautious shun curiosity for fear it will only deepen their uncertainties. Both the cautious and the confident are closed-minded, which means neither makes good judgments. It is this sense in which wisdom, which avoids extremes, improves adaptability.

Partners and partnership are critical.

A partner makes social construction easier. A partner is a second source of ideas. A partner strengthens independent judgment in the face of a majority. And a partner enlarges the pool of data that are considered. Partnerships that endure are likely to be those that adhere to Campbell's three imperatives for social life, based on a reanalysis of Asch's (1952) conformity experiment:
(1) Respect the reports of others and be willing to base beliefs and actions on them (trust);
(2) Report honestly so that others may use your observations in coming to valid beliefs (honesty); and, 
(3) Respect your own perceptions and beliefs and seek to integrate them with the reports of others without deprecating them or yourselves (self-respect).

High Reliability Organizations

There has been a great deal of discussion recently about healthcare adopting the same approaches that have facilitated high reliability organisations to achieve exceptional levels of safety despite operating in high risk high consequence environments. Examples include aircraft carriers, nuclear submarines, the nuclear power industry and aviation.
What are the features of a high reliability organisation? Are these concepts translatable to healthcare? Are there any examples of HROs in healthcare?

There are according to one expert in the field five characteristics of HROs.

•Preoccupation with failure rather than success; this is self explanatory. The HRO almost celebrates failure and actively seeks it out recognising that only by recognising the defects within it's systems can it seek to rectify those defects.
•Reluctance to simplify interpretations; always seeking the explanation especially the explanation that defines the cause of a possible future mistake.
•Sensitivity to operations; To be sensitive to operations, we must monitor a messy reality and respond to the unexpected.
•Commitment to resilience; HROs recognize that not every risk can be mitigated, but anticipate failure and ensure that redundancy is built into the system.
•Deference to expertise; instead of hierarchy structures determining responses, the decision making in a HRO migrates to the persons with most expertise in that area.

The key difference between HROs and other organisations is that they respond differently to what others would consider signals of no significance. Mindfulness is what some have described this aspect, the capability to respond strongly to weak signals and respond strongly to mitigate the potential adverse consequences of such a failure. An example in healthcare might be the test result that is delayed, a routine test of no significance but this is a warning that the system is prone to error, that a time critical result may also be delayed. The HRO responds immediately to address this failure, the Low Reliability Organisation (LRO), effectively all of healthcare, is unlikely to take any action. HROs are constantly looking for evidence of failure or potential failure. Clearly these concepts can be applied to healthcare, though the details are likely to differ. However, it is likely that the only organisation which will successfully make this transition will be those in which the culture is receptive, indeed greedy, to make this change, and in which the leadership see becoming a HRO as the number one priority of the organization. This is such a fundamental shift that it likely that very few organizations will be successful in their attempts to become HROs.

I asked two physicians recently, world experts in safety and who lead the safety/ quality efforts in their hospital, which is probably the most advanced hospital in the world in this field, where their institution was on a 1-10 scale in safety. About a 3-4 on a good day they replied. That is the characteristic of a hospital that is striving to be the best and safest in the world, but recognises that despite being the best, it has a long journey ahead.

This book is probably one of the seminal works describing HROs, and I recommend it highly. Weick & Sutcliffe
