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.
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.
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.
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.
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.
“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 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.
If the early steps are successful, though, Dulin said he would like to renegotiate to get the data provider to share more specific details on patient spending with doctors.
I’m sure there’s nothing to worry about here. Especially since the healthcare system is about to be swallowed whole by Leviathan.
