Creating Safer Healthcare
Healthcare professionals have long recognised the benefits of fostering wellness—that is, focusing on what is going right—instead of just trying to head off, or ameliorate, what might otherwise go wrong. By understanding the key determinants of good health we can keep as many patients as possible out of doctor’s surgeries and hospitals, and greatly reduce the burden of preventable diseases and ill health. In patient safety, we can, and should, be doing much the same thing.Although it may not seem immediately apparent, a similar focus on success is the best way to tackle the seemingly intractable problem of harm to patients due to adverse events in modern healthcare systems. As many as one in 10 patients in hospitals are currently harmed by care; between seven and 10 percent of patients acquire infections in hospital, and the World Health Organization estimates 20-40% of all health spending is wasted due to poor quality care
To break this impasse we need to change how we do things. To date we have defined safety as a state in which as few things as possible go wrong, or what we call ‘Safety-I’. When we do experience an adverse event or accident, we zoom in on that particular event, and work backwards to identify the exact point at which a process was derailed, often finding that ‘human error’ played a part. Consequently we often cast people as potential liabilities.
By isolating ad verse events in this way, we assume we can both understand and learn from our mistakes and so prevent them recurring. Yet virtually no serious problem ever eventuates in precisely the same way again. Meanwhile we are overlooking what is in plain sight.
Most of the time everything goes right. But no one stops to ask clinicians “How do you manage to do that?” day in and day out, within incredibly complex systems t hat operate in partly degraded states under considerable pressure. Our doctors, nurses, administrators and support staff are overwhelmingly committed to their patients and t o safety, and almost always pull it off.
Yet we don’t invest in research that could offer us invaluable insights into how our health systems manage to get millions and millions of encounters right every day; that is, what a health system looks like when it’s performing as it should, flexing and adjusting to accommodate the unexpected while still achieving its goals. Consequently, we miss the opportunity to improve safety by facilitating and supporting successes.Our familiar but outdated Safety- I approach recapitulates the thinking in safety critical industries like aviation and nuclear power in the late 20th century, when systems were less complex. We assumed neat, stable models of cause-effect relations could be used to identify a faulty part (or player) and replace it—the so-called ‘find and fix’ approach. But in healthcare today, clinical work is carried out within dynamic webs of constant interaction between many different professionals and patients interfacing with increasingly complex healthcare technologies, communication systems and equipment.
In such fast moving and often unpredictable environments it is, in
fact, people—individually and collectively— who are our key safety asset. The
unique ability of humans to constantly adjust their performance to variable
conditions and so ensure that as many things as possible go right is what we
call a ‘Safety-II’ perspective. In a ‘Safety-II’ world, research seeks to
reveal how things usually go right, as the basis for explaining how things
occasionally go wrong.
Worldwide we have made some initial progress towards understanding success. The development of standard operating protocols and clinical guidelines and the implementation of simple but effective ‘best practice’ in hand hygiene, for example, has undoubtedly saved many lives. But slavish adherence to increasingly voluminous and often piecemeal guidelines is an obstacle to flexible, intuitive, effective care. Proceduralisation cannot prevent the adverse events that continue to impose phenomenal costs on stretched health budgets and unacceptable burdens on patients and their families.We need the more holistic approach that Safety-II promises. A good starting point for this is to simply spend more time looking at what goes right as well as what goes wrong. We’ll learn far more from what works well than from what fails.
