TY - JOUR T1 - HOw can we know so little about physician referrals? AU - Katz MH Y1 - 2012/01/23 N1 - 10.1001/archinternmed.2011.1290 JO - Archives of Internal Medicine SP - 100 EP - 100 VL - 172 IS - 2 N2 - Are more patients being referred to another physician because medical care is more complicated than it was a decade ago (eg, more medicines, more procedures available), and none of us can know or do everything? Are more patients referred because as practicing doctors we are asked to do more in less time and so we refer out issues that are not in our core practice? Are our patients demanding more referrals, or are we referring more because of concerns of malpractice? Are all of these factors playing a role? The answer is unclear.
