Supporters of President-elect Barack Obama will be holding house parties to discuss ways of fixing the healthcare system over the next two weeks, and they are envisioned as a way to make good on Obama's commitment to "healthcare reform that comes from the ground up." Now some of the biggest stakeholders in the healthcare industry may get involved: The health insurance industry is encouraging its employees and satisfied customers to attend. A trade group representing some of the nation's largest healthcare businesses is organizing several meetings. And the American Medical Association and other medical societies are encouraging doctors to get involved.
