People trying to sign up for health insurance aren't the only ones confused by Obamacare. Doctors say they don't know what to expect, due to the problems with the federal and state websites. Like many American physicians, Dr. Brigit Britton expects to see a rush of new patients when the Affordable Care Act begins in January. But because of the enrollment problems, she doesn't know who they are, or how many. Britton said she's not sure what challenges doctors will face after Jan. 1. She said, "We are prepped to anticipate large numbers of patients and sicker patients, but beyond that ... we aren't sure what's going to happen."
