Chicago dermatologist Candace Thrash isn't a techie, but she does have her own interactive Web site for patients, something just half the nation’s physicians can say. On it, you can schedule or cancel an appointment, refill a prescription and print those tedious patient-history forms, which can be filled out at your leisure in Starbucks. You also can buy eye cream at 4 a.m. and scan a short bio on Thrash, who recently had her second child. If you’re scheduled for surgery, you can read pre- and post-operative instructions at your convenience. "I had no idea how much labor was involved in getting one of these off the ground,” Thrash confessed in an e-mail to friends and relatives when announcing the debut of the site, innovativedermatology.com.
