In September of 2011, Laugesen and colleagues looked at why health care in the US costs so much. Part of their analysis explored primary care physician fees. It showed that primary care docs in the US make a bit more, per office visit, than their colleagues in 5 other countries. But Americans are much less likely to have an appointment with their primary care doctors.
Laugesen also looked at orthopedic surgery in the 5 countries. Once again, the cost of American health care can NOT be blamed on the volume of procedures we do here. Instead, it is the amount of money we charge for those procedures!
