3 things to know about geomedicine

July 16, 2013 in Medical Technology

“Location, location, location” is a phrase that’s long been associated with real estate, but in recent years it’s also played a role in attempts by healthcare professionals to track disease. Now, some are putting health IT to work in adding location information – where patients have lived – into their EHRs.

“There’s a huge body of health information that’s been generated at high levels, particularly at the state and county levels, but it’s had little effect in doctors’ offices,” said Bill Davenhall, senior health adviser for ESRI, a California-based provider of geographic information systems (GIS) services to a variety of industries.

If Davenhall has anything to say about it, that’s going to change soon. In his eyes, the healthcare sector has done a great job of incorporating genetics and lifestyle into the factors considered when patients are treated, but “The third leg of the stool should be locational history.”

After all, it’s certainly worth knowing if a patient grew up near a metal manufacturing plant, for example, as chromium, which is used in metal manufacturing processes, is known to cause brain tumors.

Moreover, Davenhall added, while eating locally grown foods is a growing theme in health circles, it may not be such a wise idea if, say, the local soil has been contaminated by past industrial use or a specific toxic dumping incident.

While geomedicine, which Davenhall describes as a process of taking generalized environmental information “and pushing it into the interface between doctors and patients,” may not be a common practice now, he points to three ways that IT is helping pave the way for the use of geomedicine in the future.

Geo-coding. Most people think of an address as revolving around a street name or number of an apartment. But with GIS any address can be easily communicated in terms of longitude and latitude. According to Davenhall, one of ESRI’s current projects involves taking census bureau data and incorporating it into a reference database for use by healthcare providers. “Historically, an address has not been used as part of clinical information,” he said. “It is, however, one of the largest contextual pieces of information” because it can be matched up with a range of public databases that include the location of toxic waste sites, past industrial sites and other potential “environmental burdens.”

Curriculum development. Geomedicine may still have an exotic ring to most providers, but Davenhall said many universities and research institutions have begun developing curricula and programs that look at the intersection between location identification and technology. “The next generation (of providers) will have the expectation that health information will be located geographically,” he predicted.
