Big Data Use In Healthcare Needs Governance, Education

Using big data effectively requires everything from setting up a basic management framework to teaching analytics in medical school, says one consultant.

Healthcare organizations should adopt a standardized framework for data governance if they want to harness the power of big data, says a new report. But governance is but one element in the highly complex world of healthcare information, where many long-held practices must change, says the report, from the Institute for Health Technology Transformation (IHT2), a New York-based research and consulting firm.

Citing a 2011 McKinsey & Co. study, IHT2 said the U.S. healthcare industry could potentially save $300 billion a year with the help of advanced analytics, but healthcare organizations continue to struggle with managing and leveraging the vast stores of data they are building up.

By 2011, U.S. healthcare organizations had generated 150 exabytes -- that's 150 billion gigabytes -- of data, IHT2 said. Kaiser Permanente alone might have as much as 44 petabytes of patient data just from its electronic health record (EHR) system, or 4,400 times the amount of information held at the Library of Congress.

"It's true that big data promises to ease the transition to authentic data-driven health care, allowing healthcare professionals to improve the standard of care based on millions of cases, to define needs for subpopulations, to make more personalized decisions for individual patients, and to identify and intervene for population groups at risk for poor outcomes," the report states. "But while big data has transformed much of American industry, it's also true that massive information sharing and analysis has yet to generate significant benefits within health care."

"There are so many executives out there that just don't know where to start," IHT2 CEO Waco Hoover told InformationWeek Healthcare. Having a framework is "extremely important" to sorting it all out, he said

"A carefully structured framework for enterprise-wide data governance is arguably the first and most critical priority to ensure the success of any effort to leverage big data for health care delivery," said the report, which includes a summary of the Data Governance Institute's sample framework. The Data Governance Institute defines this framework as a "logical structure for classifying, organizing, and communicating complex activities involved in making decisions about and taking action on enterprise data."

But a management framework is not enough, says IHT2. The report recommends that healthcare organizations include providers in analytics planning because doctors often are resistant to efforts to change their practice styles. They are the ones "in the driver's seat" of care provision, so they are the most reluctant to change, Hoover said.

Healthcare organizations also need to "close the quality loop," said the report, by having data analytics specialists work closely with quality improvement teams to assure their strategies are aligned. "Achieving health care transformation requires dramatic and sustainable changes to the structure and processes of health care," the report said.

Hoover said he heard at a recent executive forum that some healthcare networks are hiring mathematicians with PhDs who "really understand how to extract data."

Longer-term, medical schools need to "bake analytics into training," according to IHT2. "It becomes a part of how medicine is practiced," Hoover explained.

"As we move forward in this new era of care, that has to be an integral part of delivering care," he continued. However, Hoover he predicted it would take 10-15 years before medical schools add this to their curriculum and start producing physicians trained in analytics.

In the meantime, more than a few provider organizations are counting on big data to help them manage population health and reduce variations in care.

"Electronic health records and automation tools already exist to identify and stratify individual patients who need special attention or care; identify care gaps; measure outcomes; and encourage patients to assume more responsibility for their health. However, they cannot store, manage, and distribute comprehensive, timely, and relevant information to the degree needed for public health management (PHM)," the report notes.

"In addition, many clinical analytics tools currently in use are quite primitive, reporting just a few basic facts and figures about a patient panel. The next generation of BI tools will have to be predictive and prescriptive to make PHM a reality."

A lot of the direction of an analytics strategy depends on how organizations define "big data," though. "What we're really talking about is leveraging your data," Hoover said, whether the database is big or small. "It's about getting value from data."

Sharp Community Medical Group, part of the Sharp HealthCare organization in San Diego, is starting to look at natural-language processing, according to medical informatics officer Dr. Neil Treister, one of the authors of the IHT2 report, because that seems to be helpful to physicians.

"[Sharp's analytics strategy] is driven by our doctors' priorities," Triester said. "Data is extremely important, but getting through their day is more important."

Triester said analytics are great for population health, but it is perhaps harder to derive benefits at the individual level. He told InformationWeek Healthcare said there has been an internal debate at the practice over how much granularity clinicians need. Many Sharp physicians are inputting a lot of data as free, unstructured text. "It doesn't make business sense to have discrete data" in some cases, according to Triester.

As large healthcare providers test the limits, many smaller groups question the value. Also in the new, all-digital Big Data Analytics issue of InformationWeek Healthcare: Ask these six questions about natural language processing before you buy. (Free with registration.)

re: Big Data Use In Healthcare Needs Governance, Education
Healthcare is maturing. Most of what is referred to currently as "analytics" consists of spotting outliers in healthcare claims - the highest cost provider; the most expensive hospital etc. or catching events - did the diabetes patient have an encounter with an opthalmologist in the least 12 months. Insurance companies have used the data for their specific need - statistically predict resource consumption of every enrollee so as to calculate risk and premium amounts. They face no serious penalty if the calculations are off the mark since they raise premiums the following year to cover losses from the prior year. But these are just algortihms used to predict disease trends and costs. With big data we will see economists, mathematicians and others bringing their modeling expertise - and that'll be the start of a new era in healthcare when time evolution will be mathematically described and calculated. We need that. Viewed as an economy, US healthcare is the 5th or 6th largest economy in the world. Imagine running a country of any size using algorithms and spotting outliers!

re: Big Data Use In Healthcare Needs Governance, Education
I agree that there has to be structure in place in order to benefit from big data analytics. The amount of information being collected can be overwhelming and without a plan as to what information you intend to use and to what purposes, a lot of the data collected may just sit there. Institutions need to work with the physicians in order to plan out what information they need and what they intend to gain from big data analytics and follow that structure.

Sadly it also needs budget. I worry that sequestration will have a pretty significant negative impact on NIH's grant money for this type of thing over the next few years if nothing is done to set the budget straight.
