In my last post, I discussed the role of physicians in patient safety in the US and UK. Today, I’m going widen the lens to consider how the culture and structure of the two healthcare systems have influenced their safety efforts. What I’ve discovered since arriving in London in June has surprised me, and helped me understand what has and hasn’t worked in America.
Before I arrived here, I assumed that the UK had a major advantage when it came to improving patient safety and quality. After all, a single-payer system means less chaos and fragmentation—one payer, one regulator; no muss, no fuss. But this can be more curse than blessing, because it creates a tendency to favor top-down solutions that—as we keep learning in patient safety—simply don’t work very well.
To understand why, let’s start with a short riff on complexity, one of the hottest topics in healthcare policy.
Complexity R Us
Complexity theory is the branch of management thinking that holds that large organizations don’t operate like predictable and static machines, in which Inputs A and B predictably lead to Result C. Rather, organizations operate as “complex adaptive systems,” with unpredictability and non-linearity the rule, not the exception. It’s more Italy (without the wild parties) than Switzerland.
Complexity theory divides decisions and problems into three general categories: simple, complicated, and complex. Simple problems are ones in which the inputs and outputs are known; they can be managed by following a recipe or a set of rules. Baking a cake is a simple problem; so is choosing the right antibiotics to treat pneumonia. Complicated problems involve substantial uncertainties: the solutions may not be known, but they are potentially knowable. An example is designing a rocket ship to fly to the moon—if you were working for NASA in 1962 and heard President Kennedy declare a moon landing as a national goal, you probably believed it was not going to be easy but, with enough brainpower and resources, it could be achieved. Finally, complex problems are often likened to raising a child. While we may have a general sense of what works, the actual formula for success is, alas, unknowable (if you’re not a parent, trust me on this).
