Sirovich et al1 make several good points about primary care physicians' overuse of technology. They did not mention, however, that new physicians often leave their residencies with little training in learning how to be comfortable with uncertainty, and consequently, some overdepend on imaging studies and laboratory tests to rule in or rule out problems.
The sheer amount of technology available may lead some of them to look askance at the value of their clinical skills and bypass them in favor of testing. This can lead to a technological addiction that is every bit as difficult to break as a substance addiction.
