Doctors aren't clamoring to chat with patients online for free; they spend enough unpaid time on the phone. Only 1 in 5 has ever E-mailed a patient, and just 9 percent are interested in doing so, according to the research firm Cyber Dialogue. "We are not stupid," says Stifling Somers, executive director of the Silicon Valley employers group. "Doctors getting paid is a critical piece in getting this to work." In the pilot program, physicians will get $ 20 per online consultation, about what they get for a simple office visit. Doctors also fear they'll be swamped by rambling E-mails that tell everything but what's needed to make a diagnosis. So the new program will use technology supplied by Healinx, an Alameda, Calif-based start-up. Healinx' s "Smart Symptom Wizard" questions patients and. turns answers into a succinct message. The company has online dialogues for 60 common conditions. The doctor can then diagnose the problem and outline a treatment plan, which could include E-mailing a prescription or a face-to-face visit. Can E-mail replace the doctor's office？ Many conditions, such as persistent cough, require stethoscope to discover what's wrong and to avoid a malpractice suit. Even Larry Bonham, head of one of the doctor's groups in the pilot, believes the virtual doctor's visits offer a "very narrow" sliver of service between phone calls to an advice nurse and a visit to the clinic. The pilot program, set to end in nine months, also hopes to determine whether online visits will boost worker productivity enough to offset the cost of the service. So far, the Internet's record in the health field has been underwhelming. The experiment is "a huge roll of the dice for Healing", notes Michael Barrett, an analyst at Internet consulting firm Forester Research. If the "Web visits" succeed, expect some HMOs (Health Maintenance Organizations) to pay for online visits. If doctors, employers, and patients aren't satisfied, figure on one more E-health start-up to stand down. The Silicon Valley employers promote the E-health program for the purpose of ______. A．rewarding their employees B．gratifying the local hospitals C．boosting worker productivity D．testing a Sophisticated technology
