How big data will save your life

Lucas Mearian | April 26, 2013
Dr. Robert Walker, director of health innovation for the U.S. Army Surgeon General, has been more a frustrated data entry clerk in recent years than a physician, a frustration shared by thousands of his colleagues.

"The best way to correct glucose levels is to know what's happening with a patient when they're at home, not when they're in a doctor's office," Harris said.

Also being floated in the heathcare community are scalable, less expensive and more patient-centric community health record banks. Those banks are community organizations that put patients in charge of a comprehensive copy of all their personal, private health information, including both medical records and optional information added by the patient.

The patient explicitly controls who has access to which parts of the information in his or her individual account.

Voice recognition joins big data

But, before information can be shared, it needs to make it into EHRs. One way physicians and nurses can add their notes to EHRs is with voice recognition technology.

For example, the U.S. Army has an enterprise-wide license for Nuance's Dragon Medical 360 Network Edition voice recognition software for use with its AHLTA EHR and Essentris-Inpatient System. The U.S. Veteran's Administration also has 12,000 Nuance Dragon licenses integrated with VistA EHR system.

In many cases, a physician will use voice recognition to enter observations, prognosis and treatment into a patient's electronic record.

Dr. Walker, with the U.S. Army's Surgeon General's Office, uses voice recognition technology as he examines a patient to populate their record. A wide-screen monitor in his exam room allows the patient to view the data as it's being input so any errors can be corrected, he said.

Walker believes the real game changer in medicine will be an engaged patient, one who will enter his or her own data through the use of mobile devices. And that data can include not just medical information, but also lifestyle updates involving diet and exercise.

By having a full picture of a patient's lifestyle, doctors are better equipped to help patients avoid the onset of chronic illnesses. Then, once the data is in an EHR, big data analytics engines could offer physicians information about patients who may need to adjust their caloric intake, level of activity or the amount of sleep they get.

"The answer to the obesity problem is not the operating table, but the dinner table, and that's where we need to get to," Walker said. "In this country, we're putting billions of dollars into healthcare and our life expectancies are less than in countries that spend a fraction of what we do.

"We're really doing disease care and not healthcare today," he said.
