In the latest sign that consumerism is becoming a major force in the healthcare industry, Indianapolis-based Angie's List unveiled a new service that allows its members to rate physicians, dentists, pharmacies and health insurers. Doctors and hospitals, though, are expressing some concerns. Angie's List--which has 600,000 members nationwide, including 43,300 in the Indianapolis area--built its business by providing a forum for its customers to rate painters, roofers and other service providers. Now, the company allows members to log on to www.angieslist.com to share their real-life experiences with local doctors, from the cleanliness of waiting rooms to the physician's bedside manner.
