"The data is already used to market to people to get them to do things that might not always be in the best interest of the consumer, we are looking to apply this for something good," Dulin Omega Seamaster I Guld
While both sell to health insurers, they said it's to help those companies offer better services to members.
"Most of these things you can find out just by looking at the patient and seeing if they are overweight or asking them if they exercise and discussing that with them," Murry said. "I think it is a waste of time."
Acxiom Corp. and LexisNexis are two of the largest data brokers who collect such information on individuals. They say their data are supposed to be used only for marketing, not for medical purposes or to be included in medical records.
You may soon get a call from your doctor if you've let your gym membership lapse, made a habit of picking up candy bars at the check out counter or begin shopping at plus sized stores.
"What we are looking to find are people before they end up in trouble," said Dulin, who is also a practicing physician. "The idea is to use big data and predictive models to think about population health and drill down to the individual levels to find someone running into trouble that we can reach out to and try to help out."
While all information would be bound by doctor patient confidentiality, he said he's aware some people may be uncomfortable with data going to doctors and hospitals. For these people, the system is considering an opt out mechanism that will keep their data private, Dulin said.

If the early steps are successful, though, Dulin said he would like to Nike Jacket Hoodie Blue renegotiate to get the data provider to share more specific details on patient spending with doctors.
while Pennsylvania's biggest system uses household and demographic data. Patients and their advocates, meanwhile, say they're concerned that big data's expansion into medical care will hurt the doctor patient relationship and threaten privacy.
The system may also score the probability of someone having a heart attack by considering factors such as the type of foods they buy and if they have a gym membership, he said.
Murry, the diabetes patient from Charlotte, said she already gets calls from her health insurer to try to discuss her daily habits. She usually ignores them, she said. She doesn't see what her doctors can learn from her spending practices that they can't find out from her quarterly visits.
Carolinas HealthCare System operates the largest group of medical centers in North Carolina and South Carolina, with more than 900 care centers, including hospitals, nursing homes, doctors' offices and surgical centers. The health system is placing its data, which include purchases a patient has made using a credit card or store loyalty card, into predictive models that give a risk score to patients.
For a patient with asthma, the hospital would be able to score how likely they are to arrive at the emergency room by looking at whether they've refilled their asthma medication at the pharmacy, been buying cigarettes at the grocery store and live in an area with a high pollen count, Dulin said.
Much of the information on consumer spending may seem irrelevant for a hospital or doctor, but it can provide a bigger picture beyond the brief glimpse that doctors get during an office visit or through lab results, said Michael Dulin, director of research and evidence based medicine at Carolinas HealthCare System.
While the hospital can share a patient's risk assessment with their doctor, they aren't allowed to disclose details of the data, such as specific transactions by an individual, under the hospital's contract with its data provider. Dulin declined to name the data provider.
That's because some hospitals are starting to use detailed consumer data to create profiles on current and potential patients to identify those most likely to get sick, so the hospitals can intervene before they do.
"It is one thing to have a number I can call if I have a problem or question, it is another thing to get unsolicited phone calls. I don't like that," said Jorjanne Murry, an accountant in Charlotte, North Carolina, who has Type 1 diabetes. "I think it is intrusive."
Within the next two years, Dulin plans for that score to be regularly passed to doctors and nurses who can reach out to high risk patients to suggest interventions before patients fall ill.
"You have to have a relationship, it just can't be a phone call from someone saying 'do this' or it just feels creepy," he said. "The data itself doesn't tell you the story of the person, you have to use it to find a way to connect with that person."
Information compiled by data brokers from public records and credit card transactions can reveal where a person shops, the food they buy, and whether they smoke. The largest hospital chain in the Carolinas is plugging data for 2 million people into algorithms designed to Nike Vapormax Camo
