LINDA WERTHEIMER, HOST:
The Internet has made the world of medicine much more accessible to the average person; with websites and blogs dedicated to helping diagnose illnesses, or better understand symptoms. A federal law, passed in 2009, took that a step further, calling on physicians to offer their patients online communication.
The idea is, having online access to your physician will cut down on the number of doctor visits. But new research suggests that actually, the opposite is true. Eric Whitney, of Colorado Public Radio, reports.
ERIC WHITNEY, BYLINE: Dr. Ted Palen is an internist in Denver. He says it's pretty common for him to see a patient in his office, and then think...
DR. TED PALEN: You know, we could've handled this by email.
WHITNEY: Palen, who's also a researcher, wanted to see if offering patients online access to their doctors would mean they'd need to come in to the office less often. Previous studies found around a 20 percent drop in patient visits, once they had online access. But Palen's much larger study, just published in the Journal of the American Medical Association, showed that patients with online access actually scheduled more visits.
PALEN: The finding really did surprise us; this association between online access, and an increase in in-person services.
WHITNEY: Why the increase? Palen says it could be that patients who signed up for online access were sicker than those who didn't, although he says his study tried to control for that. It could be that doctors who aren't used to an online give-and-take with patients, asked them to come in more often, to clear things up. Or it could be that the new, online relationship between doctors and patients means that together, they're catching important health indicators that were getting missed in the past; and patients are getting better care.
JUDY MURPHY: In certain cases, with certain diseases, the more frequent visits actually make more sense.
WHITNEY: Judy Murphy is an information technology coordinator at the Department of Health and Human Services, the federal agency that's requiring doctors to start offering patients online access. She says for some, online access to doctors will mean fewer visits; for others, it will mean more. It depends on the patient. And the government's intent in requiring doctors to offer online access, Murphy says, isn't to drive the overall number of office visits up or down; but to improve the relationship between doctors and patients, with better communication.
MURPHY: We have all sorts of individuals right now, who actually think their health conditions are the doctors' problem - and not theirs. And I think that's what we're really trying to focus on; helping the patients see that when they get engaged in their care, and when they become part of the therapy plan, that they can actually have better outcomes.
WHITNEY: There's no definitive research linking more online access to doctors, to better patient outcomes. But many doctors are optimistic. Dr. Jeff Cain is the president of the American Academy of Family Physicians.
DR. JEFF CAIN: It's a new form of medical care, that offers the promise to be able to improve care.
WHITNEY: Cain says doctors and patients are both still learning what they can accomplish online together; and whether that means more, or fewer, office visits. The answer is important, both in terms of planning future health system capacity, and because most doctors still get paid based on the number of office visits, and not for answering emails.
CAIN: This is something that our current health care system doesn't pay for, so it's coming out of my spare time.
WHITNEY: An estimated 70 million Americans now have access to online communication with their doctors, a number that's expected to grow rapidly in the next few years. Whether that means more overtime for doctors, or better health care - or both - are topics for studies that are just now getting started.
