User-created content and communications on Web-based applications, such as networking sites, media sharing sites, or blog platforms, have dramatically increased in popularity over the past several years, but there has been little policy or guidance on the best practices to inform standards for the professional conduct of physicians in the digital environment. Areas of specific concern include the use of such media for nonclinical purposes, implications for confidentiality, the use of social media in patient education, and how all of this affects the public's trust in physicians as patient-physician interactions extend into the digital environment. Opportunities afforded by online applications represent a new frontier in medicine as physicians and patients become more connected. This position paper from the American College of Physicians and the Federation of State Medical Boards examines and provides recommendations about the influence of social media on the patient-physician relationship, the role of these media in public perception of physician behaviors, and strategies for physician-physician communication that preserve confidentiality while best using these technologies.

The Patient Protection and Affordable Care Act, signed into law in 2010 and upheld by the U.S. Supreme Court last year, is expected to provide health care coverage to as many as 32 million Americans by 2019. As demand for health care expands, the need for accurate data about the current and future physician workforce will remain paramount. This census of actively licensed physicians in the United States and the District of Columbia represents data received from state medical boards in 2012 by the Federation of State Medical Boards. It demonstrates that the total population of licensed physicians (878,194) has expanded by 3% since 2010, is slightly older, has more women, and includes a substantive increase in physicians who graduated from a medical school in the Caribbean. As state medical boards begin to collect a Minimum Data Set about practicing physicians and their practice patterns in the years ahead, this information will inform decisions by policymakers, regulators and health care market participants to better align health care demand with supply.

Only 5% of IM residents do not achieve IM certification. IM resident attrition minimally impacts physician supply, though those without certification appear to contribute disproportionately to poor physician performance indicators. Improved tracking of the U.S. physician workforce could aid policy makers in predicting manpower shifts in certain specialty areas, both during and after residency training.
