EX: It's generally accepted that people get sick going to the doctors office and being around sick people. Reducing this by installing UV lights is viable even if such illnesses where not any specific persons fault.
I am especially irked by the constant airplane analogies. Healthcare is not comparable to an assembly line nor modern aviation. The checklists/verifications/pathways only work when you take pretty healthy people and you submit them to a standardized, elective, safe procedure. In those cases, errors are obvious, and the efficacy of any quality improvement method is easy to assess.
Unfortunately, in most cases, healthcare works like a completely chaotic, black box kind of system, in which the output can hardly be predicted with any kind of certainty. It is easy to get excited by "quality initiatives" which may improve the one tiny and unimportant outcome that we measure, all while not realizing the severe side effects it causes on other outcomes.
