Individualised care or anaesthetist preference: an uncomfortable question

There is widespread variation in how anaesthesia is provided to individual patients even for the same types of surgery. This variation exists within departments, between hospitals, and between countries. Patient and surgical factors are often cited as a justification for variation. Local and national norms, guidance, and standards, and the positive or negative roles of key opinion leaders likely all play a part. Although clinicians may disagree where the line falls between warranted and unwarranted variations, at least some of this variation is down to anaesthetist preference, not individualised patient care.
