About 25% of Americans live in rural communities while a mere 10% of physicians practice there, says the study’s lead author, Coleman Drake, PhD, an assistant professor in the department of health policy and management at the University of Pittsburgh Graduate School of Public Health. And making matters worse, people who live out in the country tend to be older and sicker than their urban counterparts.
“Over the last decade especially, there has been considerable interest in the potential for telehealth to make it easier to access healthcare,” Mr. Drake says. “We wondered if telemedicine really could help bridge the gap in access to care. And we discovered that in a lot of rural areas, the lack of access to broadband is potentially limiting access to telehealth.”
To see whether telemedicine could make a difference where doctors were sparse, Drake and his colleagues first mapped out the areas where access to primary care physicians or specialists might require driving an hour or more, according to the study published in the Annals of Internal Medicine, May 20.1
Then, to determine access to broadband, the researchers turned to data from the Federal Communications Commission to find out whether people who lived in counties with distant drives to doctors had a way to download data at a speed of at least 25 megabits per second, which is sufficient to support video-based telehealth visits.
Mr. Drake and his colleagues discovered that the percentage of subscribers to broadband services decreased with increasing distance from cities, with rates of 96% in urban counties, 82.7% in rural counties and 59.9% in counties with extreme access considerations. Further, in counties where there was inadequate access to primary care physicians and psychiatrists (meaning no primary care provider within a 70-minute drive, for example) the subscription rate was 38.6%.
Even if the broadband issue was solved, it wouldn’t mean that all barriers to telemedicine would be overcome, Mr. Drake says. Right now, “Medicare, with few exceptions, doesn’t reimburse for telemedicine visits from home,” he explains.
What’s needed is for “policy makers at the local, state and federal level who are considering the cost effectiveness of infrastructure expansions to consider that you’re not just letting people get on social media in their spare time, you could also be allowing people to access telemedicine who might otherwise not be able to,” Mr. Drake says.
