Ardis Hoven is an HIV specialist-based in Lexington, Ky. who, last month, was elected president of the American Medical Association. Earlier this week, she learned of the Supreme Court decision. Hoven was happy to see the news: The AMA has long supported the Affordable Care, even though doctors look to be split in their opinion of the law. While the law will take big steps toward expanding insurance coverage, Hoven cautions there are still big challenges for doctors ahead. We spoke Friday about the country's shortage of doctors, how she and others will "teach" new patients to use their health insurance and what role physicians play in team-based healthcare.
