The Need For A Smart Approach To Big Health Care Data



January 27th, 2014

Today, academic medicine and health policy research resemble the automobile industry of the early 20th century — a large number of small shops developing unique products at high cost with no one achieving significant economies of scale or scope. Academics, medical centers, and innovators often work independently or in small groups, with unconnected health datasets that provide incomplete pictures of the health statuses and health care practices of Americans.

Health care data needs a “Henry Ford” moment to move from a realm of unconnected and unwieldy data to a world of connected and matched data with a common support for licensing, legal, and computing infrastructure. Physicians, researchers, and policymakers should be able to access linked databases of medical records, claims, vital statistics, surveys, and other demographic data. To do this, the health care community must bring disparate health data together, maintaining the highest standards of security to protect confidential and sensitive data, and deal with the myriad legal issues associated with data acquisition, licensing, record matching, and the Health Insurance Portability and Accountability Act of 1996 (HIPAA).

Just as the Model-T revolutionized car production and, by extension, transit, the creation of smart health data enclaves will revolutionize care delivery, health policy, and health care research. We propose to facilitate these enclaves through a governance structure know as a digital rights manager (DRM). The concept of a DRM is common in the entertainment (The American Society of Composers, Authors and Publishers or ASCAP would be an example) and legal industries.  If successful, DRMs would be a vital component of a data-enhanced health care industry.

Giving birth to change. The data enhanced health care industry is coming, but it needs a midwife. There has been explosive growth in the use of electronic medical records, electronic prescribing, and digital imaging by health care providers. Outside the physician’s office, disease registries, medical associations, insurers, government agencies, and laboratories have also been gathering digital pieces of information on the health status, care regimes, and health care costs of Americans. However, little to none of these data have been integrated, and most remain siloed within provider groups, health plans, or government offices.

In the past, technical and cost issues have restricted efforts to share and integrate health care datasets. However, advances in technology permit a bold vision of a new infrastructure involving shared access to big data, computing power, and analytic tools. The resources exist to access and analyze extremely large health data sets in the secure, HIPAA compliant, computing environments of data enclaves. Data enclaves are a “secure computing environment, firewalled from outside intrusion, accessible only by authorized users, that allows for remote access to microdata where the inflow and outflow are controlled and monitored by either experienced confidentiality officers or by algorithms, whereby users have access to analytic tools and only those data they are licensed to use.”

The governance issues. What remain to be resolved is how to legally and administratively bring the data together:

  1. how multiple stakeholders will provide data under standard contribution agreements;
  2. how to link extremely large and multi-year files, match records across datasets, and provide statistical deidentification where necessary; and
  3. how to license these data to multiple researchers under standard use agreements.

As stated above, we suggest that these tasks be solved by a digital rights manager.

How the DRM will work. Data owners, such as provider groups, are reasonably concerned about unfettered access to data. Therefore, the DRM’s most important job will be to provide a low-cost, reliable, and technically and legally protective environment in which data owners are comfortable placing their data. The DRM will negotiate data contribution agreements with each data owner, and the DRM will grant access to data users consistent with these agreements. Thus, a DRM will reduce the burden on potential data contributors giving them greater incentive to participate and share data by allowing them to deal with a single responsible party.

The DRM will also have a responsibility for fulfilling all the legal requirements that must be met—under HIPAA, state law, or otherwise—relative to the uses of the data. The DRM will also negotiate software-licensing agreements and arrange for commonly required intermediate value added services such as encrypted provider or individual identifiers or statistical de-identification. To do so, the DRM will require specialized expertise in the HIPAA, statistical de-identification, and an enhanced institutional review board with an understanding of big data risks and opportunities.

Under this governance structure, health data owners who want to generate useful insights from their health data can do so securely. Their data, when shared, will be secure, their confidential information will remain protected, and they will not be burdened with administrative expenses associated with distribution, licensing, or oversight associated with their data. In essence, all of these tasks can be efficiently contracted out to a common technology platform entity so as to reduce the burden on data owners, thereby making more likely that they will share their data. Thus, together, the DRM and the data enclave can transform health data into smart data (Figure 1).

Great benefits and manageable risks. The potential benefits of smart health data are great, but data must be actionable. To that end, the previously outlined governance structure removes barriers and creates new opportunities. For patients, the enclave will be an opportunity to receive better care from evidence-based practice and personalized medicine. For physicians, more complete and accurate patient information will enable the delivery of better care. For health policy researchers and policymakers, linked data will allow for a better understanding of trends and the impacts of policy initiatives. As a result, the enclave offers an efficient setting in which to engage in comparative and cost effectiveness research.

Some may question the wisdom of hosting so much data. We believe that smart data enclaves will mitigate the risks to patients and providers. As a country, we are missing an opportunity to maximize the gains from the already expended effort to create EHRs and from nearly two decades of HIPAA compliant health data use. Entire generations of medical professionals and researchers are unfamiliar with administrative claims and registry data due to the absence of cost-reducing shared infrastructure. The question should not be whether we should have a smart health data world, but how soon can we make it happen.

    DRM is fine, but for patient care there is another option. Patients need to hold their own data as they take control of their healthcare costs as well as their health. A well informed individual presenting to your office with a “packet” from his PMD in 1976 can now enters your office with a “jump” drive complete with angiograms. In 1983 PreOps, Inc. proposed such a scheme on the old “floppy discs” and later on mini CD-Roms that would enable patients to be in control of their data We became concerned over patient privacy with the advent of the internet and tabled the program. Now, all that is needed to effect the same goal is for the patient to establish a secure “file” in the cloud and access it as needed for the provider. We found that patient familiarity with data control, pricing and treatment options led to more involvement with their own care. This has to be worth someting!!

    Henry Ford would never have purchased an operative procedure in a hospital outpatient department when he could get the same care in a freestanding unit for 40% less!

    The benefits of

    o “For patients, the enclave will be an opportunity to receive better care from evidence-based practice and personalized medicine.
    o “For physicians, more complete and accurate patient information will enable the delivery of better care.”

    can be thought of as “local” and are already capable of being met, as evidenced by the many journal articles describing the use of healthcare data to analyze, optimize, and predict. It requires the will of local leadership and a set of known capabilities. Additionally, the data “enclave” described n the blog can hide local effects due to its global perspective – known as the “Simpson” paradox.

    The benefit of

    o “For health policy researchers and policymakers, linked data will allow for a better understanding of trends and the impacts of policy initiatives.”

    can be thought of as “global” *might* be better achieved through the approach recommended by this blog.

    Please note that while the term digital rights management was used in the software and recording industry, the concept as used here is not at all the same.

  5. Fred Trotter Says:

    What you are suggesting is something pretty similar to the “Health Data Bank” that floated for years… in that respect it is an interesting idea… and worthy of discussion.

    But you are referencing a technology stack with DRM that is universally regarded as a broken technology, which means that no reasonable technology strategy can be built on top of it.

    DRM makes it difficult for people with legitimate access to data to leverage that data. People who want to do naughty things like share DVD’s or illegally upload/download other peoples copyrighted music online just learn to work around DRM. So its basically missing for anyone with ill-intent and inconvenient for anyone who is honest.

    Most importantly DRM as a technology has no practical application in Health IT. If you have a successful DRM-based access to Lady Gaga’s latest signal then you can play it but not upload it to the Internet. If you had DRM-based access to Lady Gaga’s health record then you can see that she recently had gallstone surgery (or whatever) and then you know that and you can call the newspaper and tell them. DRM as a technology just does not apply.

  6. Bob Marsh Says:

    I wholeheartedly agree with Dr. Parry’s comment. The value, cost reduction and productivity metrics MUST be identified to create a compelling “case study” that shows value to the providers, employers, and most important, the patient. Put another way… in God we trust… all others bring data!

  7. Dr. Thomas Parry Says:

    The commentary raises important points on healthcare data but from the employer’s standpoint, there needs to be an expansion based on the question of what factors important to the employer does employee health impact — certainly healthcare costs but also absence, disability, employee performance and ultimately key business metrics. Sooner rather than later, benefit managers, HR directors and Risk Managers need to answer the key CFO question: what are we getting as a business for investments in health and better care.
