Practice style variation at the regional level has been well documented at different geographic levels, but there is much less research focusing on the role of individual physician variability in practice. Two studies1,2 have shown considerable variation in the practice styles of cardiologists who treat patients with acute myocardial infarction and obstetricians who perform cesarean-sections, but less is known about how the use of nonrecommended or “low-value” care varies across physicians.
