An interesting article titled Physicians Treating Physicians: Information and Incentives in Childbirth explores the difference in patient care that physicians receive when pregnant.
From the paper:
We find that physicians are less likely to get C-sections and have better health outcomes than comparable non-physicians. In addition, non-physician-patients’ treatment intensity covaries with their providers’ financial incentives, while physician-patients appear unaffected. Our preferred explanation for thesefindings is that physician-patients are more informed about the appropriate level of care. Even among physicians, those in specialties with the most relevant medical knowledge receive the least intensive treatment.
