Value added for physicians

8 Oct

I frequently post about value added measures of teaching, arguing that these measures are statistically invalid, and, thus, unfair to teachers.

Now an NBER paper claims that we should use value added measures to evaluate physicians. I do not see how these measures would be any more valid for doctors. The course of a patient’s illness are affected by many factors, such as; genetic predispositions, accuracy of lab tests, the timeliness of treatment, and the differential efforts and skills of a number of medical professionals. If patients are not assigned to health care providers randomly, and they clearly are not, than there is no way to extract the value added by individual physicians.
