Objective: To determine whether the type of practice to which physicians belong influences the types of medications they prescribe

Methods: The study used data from the National Ambulatory Medical Care Survey (NAMCS) to conduct a series of regressions for two pairs of medications. The first pair was for the treatment of high cholesterol. Advicor was the new medication and Lovastatin was the competitor. The second pair was for the treatment of arthritis. Humira was the new medication and Remicade was the competitor. For each pair, there were two sets of regressions that consisted of an unrestricted regression with all patients in the sample and a restricted regression limited to recipients of the two medications.

Results: The results of the study showed solo physicians were more likely to prescribe Advicor over Lovastatin, but less likely to prescribe Humira over Remicade.

Conclusions: The study suggests there is a difference present in the prescriptions written in solo versus group physicians and additional factors dealing with the specific drug must determine the direction of this difference.
