Does Telemedicine Work?

With the days of routine doctors' house calls long gone, many patients have turned to telemedicine to get quick, convenient diagnoses.

While 30 million American said they have consulted their doctor via e-mail and another 70 million said they wish they could, only a third of doctors actually offer e-mail or telephone appointments, according to Manhattan Research, a market research and advisory firm for pharmaceutical and health care companies.

So many patients have turned to online resources to help pinpoint their problems.

Several online sites offer symptom checkers and access to medical experts — allowing patients to ask doctors for advice without ever meeting them face to face. But some critics question just how reliable such resources can be.

"Good Morning America" and "GMA" medical contributor Dr. Marie Savard decided to check some medical Web sites to see how they would advise a patient based on her stated symptoms.

The Test

First "GMA" took advantage of a free media trial at the subscription site Edocamerica.com. "GMA" asked for advice for one of Savard's patients, a 35-year-old woman with unexplained itching and fatigue.

Savard knew what was wrong with the patient. Edocamerica.com suggested the patient get blood tests to check for an underactive thyroid.

While the suggestion was reasonable, underactive thyroid was not the patient's problem.

Then "GMA" tried another site called LivePerson. The site posts doctors' pictures and credentials. Users pay by the minute or question for advice.

"It's totally, totally upsetting. It totally reduces medicine to piecemeal work," Savard said.

For $25, the LivePerson doctor also pointed to hypothyroidism. He suggested the woman get tested for diabetes, too.

Finally, "GMA" tried a site called Just Answer, where patients can get advice on what's ailing their cars as well as what's ailing their bodies. The price ranges from $9 to $30.

"I'm totally skeptical," Savard said before receiving the diagnosis.

In just 3½ minutes a doctor responded, "You are having an attack of acute urticaria." He didn't suggest the patient get checked for the skin allergy; rather he said she "had it."

Only when pressed did he mention other possibilities, such as liver and kidney disease.

The True Diagnosis

Still, the doctor was incorrect. Figuring out Savard's patient's problem without the benefit of a physical exam could be difficult for any physician. A physical exam would have revealed her enlarged lymph nodes — a hallmark of a cancer called Hodgkin's disease.

LivePerson and Just Answer both said they are not responsible for the advice their experts give. All three Web sites said they are not intended to be substitutes for people's personal doctors. They all recommended testing, which would have resulted in a doctor's visit.

Savard's real-life patient kept asking her primary care physician to prescribe skin creams over the phone, and before she finally sat with Savard for an in-person appointment and second opinion.

"By her failing to go to her doctor's office and getting that hands on exam, she delayed that diagnosis many months," Savard said.

Telemedicine With Your Local Doctor

A much more common — and less controversial — practice is regular doctors who make telemedicine a part of their practice. Dr. Alan Dappen knows all his patients and requires them to see him for a face-t- face exam before treating them remotely.
