I would argue that a doctor has a lot of decisions made for them. A doctor would ask the patient more questions to get an idea of the symptoms, run some checks and narrow down the possibilities until they hopefully arrive at a diagnosis. They would utilise their knowledge of the human body and they would have ample resources and texts to refer to for assistance. This is very similar to how one might diagnose a technical issue in the aircraft by analysing the warnings, indications etc and diagnosing the issue and following the prescribed checklist. You could argue that a doctor doesn't have a checklist in front of them, but perhaps if they had to make big decisions in a short time frame whilst managing numerous other tasks at the same time, a handbook akin to a QRH might be beneficial.
