![]() Dr Gawande’s NEJM paper introduction of checklists decreased the inpatient mortality by half and reduced inpatient complication rates by one third. It contained 22 items that are supposed to be checked before induction of anaesthesia, before skin incision and before the patient leaves the operating room. In 2009 the WHO checklist project, driven by general surgeon Dr Atul Gawande was published. While not all complications are the results of errors, checklists can prevent errors and therefore reduce complication rates. If my surgery goes really smooth, my scrub nurse would be so much on my side and with me at the operation that she would exactly know what we are doing at every step she would recognise difficulties and problems without me saying a word. I work at my best if I don’t actually need to ask my scrub nurse for a particular instrument. Let alone to verbalise things that must not be touched, etc. Every surgeon knows that it is virtually impossible to verbalise all tasks that need to be done. We notice it when people involved in a surgical procedure are unfamiliar with it or if staff doesn’t exactly know what to do and how to assist with the procedure. Surgery is a rather complex undertaking and sometimes we only notice complexity when things don’t go well or fall apart. Would aviation be as (un)safe as medicine, no one would fly. There are numerous similarities and dissimilarities between the aviation industry and medicine. The idea of pilot checklists was born and it is now unthinkable to fly any aircraft without checklists. With those check lists in place 12 aircraft managed to fly 1.8 million miles without a serious accident. They developed four checklists: one for take-off, flight, prior to landing and after landing. It was simply too complex for any one’s memory. They were sure that the model was not too much of a plane to fly. Some pilots sat down afterwards to analyse the accident. The public opinion at the time was Boeing 299 was “too much a plane for one man to fly”. Once the plane was in the air the engineers apparently realised the mistake and tried to reach the lock handle but it was too late. The pilots had forgotten to release a lock prior to take-off. From five people on board two died of their injuries.Īn investigation found “pilot error” as the cause. The aircraft toppled over and fell, bursting into flames upon impact. It began a smooth climb but then suddenly stalled. ![]() At formal testing the aircraft made a normal taxi and take-off. The Boeing plane seemed to be superior to any of the other two aircraft. In 1934 the US Army evaluated 3 different aircrafts for testing, including the Boeing model 299.
