Reformers in the health care field, quite properly, emphasize new payment models and culture changes to drive improvements in outcomes. But we can’t ignore the barriers that current technology puts in the way of well-meaning reformers. This article discusses one of the many companies offering a patient health record (PHR) and the ways they’ve adapted to a very flawed model for data storage and exchange.

I had the honor to be contacted by Dr. Hirdey Bhathal, CEO/Founder of ZibdyHealth. Like many companies angling to develop a market for PHRs, ZibdyHealth offers a wide range of services to patients. Unlike, say, Google Health (of blessed memory) or Microsoft HealthVault, ZibdyHealth doesn’t just aspire to store your data, but to offer additional services that make it intensely valuable to you. Charts and visualizations. for instance, will let you see your progress with laboratory and device data over time. They call this a “Smart HIE.” I’ll look a bit at what they offer, and then at the broken model for data exchange that they had to overcome in the health care industry.

The ZibdyHealth application

Setting up an account with ZibdyHealth is as easy as joining Facebook. Once you’re there, you can create health information manually. The company is working with fitness device makers to allow automatic uploads of device data, which can then be saved as a standard Continuity of Care Document (CCD) and offered to doctors.

You can also upload information from your physician via their health care portal–with a degree of ease or difficulty depending on your provider–and share it with other clinicians or family members (Figure 1). You have fine-grained control over which medications, diagnoses, and other information to share, a form of control called segmentation in health care.

Dr. Bhathal would like his application to serve whole families and teams, not just individuals. Whether you are caring for your infant or your aging grandmother, they want their platform to meet your needs. In fact, they are planning to deploy their application in some developing nations as an electronic medical record for rural settings, where one healthcare provider will be able to manage the health data for an entire village.

Currently, ZibdyHealth allows speciality clinics to share information with the patient’s regular doctor, helps identify interactions between drugs provided by different doctors, and allows parents to share their children’s health information with schools. This consolidation and quick sharing of medical information will work well with minute clinics or virtual MD visits.

ZibdyHealth is HIPAA-compliant, and support highly secure 256-bit AES encryption for data exchange. Like health care providers, they may share data with partners for operational purposes, but they promise never to sell your data–unlike many popular patient networks. Although they sometimes aggregate anonymized data, they do so to offer you better services, not to sell it on the market or to sell you other services themselves.

In some ways, ZibdyHealth is like a health information exchange (HIE), and as we shall see, they face some of the same problems. But current HIEs connect only health care providers, and are generally limited to large health care systems with ample resources. PHR applications such as ZibdyHealth aim to connect physicians and patients with others, such as family members, therapists, nursing homes, assisted care facilities, and independent living facilities. In addition, most HIEs only work within small states or regions, whereas ZibdyHealth is global. They plan to follow a business model where they provide the application for free to individuals, without advertisements, but charge enterprises who choose the application in order to reach and serve their patients.

Tackling the data dilemma

We’d see a lot more services like ZibdyHealth (and they’d be more popular with patients, providers, and payers) if data exchange worked like it does in the travel industry or other savvy market sectors. Interoperability will enable the “HIE of one” I introduced in an earlier article. In the meantime, ZibdyHealth has carried out a Herculean effort to do the best they can in today’s health exchange setting.

What do they use to get data from patient portals and clinicians’ EHRs? In a phrase, every recourse possible.

  • Many organizations now offer portals that allow patients to download their records in CCD format. ZibdyHealth works with a number of prominent institutions to make uploading easy (Figure 2). Or course, the solution is always a contingent one, because the provider still owns your data. After your next visit, you have to download it again. ZibdyHealth is working on automating this updating process so that providers can feed this information to the patient routinely and, by uploading the discharge CCD as part of a patient’s discharge process, ensure an easy and accurate transition of care.

  • If providers aren’t on ZibdyHealth’s list of partners, but still offer a CCD, you can download it yourself using whatever mechanism your provider offers, then upload it to ZibdyHealth. ZibdyHealth has invested an enormous amount to parse the various fields of different EHRs and figure out where information is, because the CCD is a very imperfect standard and EHRs differ greatly. I tried the download/upload technique with my own primary care provider and found that ZibdyHealth handled it gracefully.

  • ZibdyHealth also supports Blue Button, the widely adopted XML format that originated at the VA as a text file.

I see ZibdyHealth as one of the early explorers who have to hew a path through the forest to reach their goal. As more individuals come to appreciate the benefits of such services, roads will be paved. Each patient who demands that their doctor make it easy to connect with an application like ZibdyHealth will bring closer the day when we won’t have to contort ourselves to share data.
