When it comes to nationwide seamless health data inseparability, persons may disagree on the actual definition, but they can surely agree on 1 thing: We do not have it now.
There is been important growth on few applications, like Direct secure messaging, exchanging of continuity of care documents and e-prescribing. And in some geographic places, health data exchanges have great participation and advanced capabilities that have been established over decades.
Vendor-based attempts such as Epic Systems Care Everywhere and the multivendor network CommonWell Health Alliance are famous with their consumers, however neither claims universality. CommonWell rolled out nationwide in the year 2015 and claims 5,000 contributors in its network, while Epic’s Care Everywhere claims more than 300 participating customers, each representing numerous contributors. In the month of April 2015, both networks dropped few of their charges to contributors for sharing data, in part a reaction to a report from the Office of the National Coordinator for Health IT condemning industry practices that result in “data blocking.”
But for the most part, data sharing among unrelated contributors—however increasingly necessary in a world moving toward value-based care —is erratic, clunky, inconvenient and not just ready to have the promised influence on decreasing costs and making better the quality of care.
“I need to be capable to look at a unified diabetes flowsheet with data from everywhere the care was done,” states Danny Sands, MD, a medical informatics expert who also practices internal medicine at Beth Israel Deaconess Medical Center in Boston. “Merely flipping screens and looking at data from other places does not solve my issue. If it is too difficult to look at the data, it becomes easier to reorder the tests.” He is chronically annoyed by the inability of unrelated institutions—even those right across the street from each other in Boston’s hospital-dense Longwood Medical Area—to integrate their data.
“It is all about the workflow,” claims Chuck Christian, vice president of technology and engagement for the Indiana Health Information Exchange. “If you desires to have a bad day with physicians, mess up their workflow or make them learn a latest one that they consider is less effective.”
From a physician’s perspective, analyzing at a [Consolidated Care Document] is like rummaging through a “junk drawer” in search of that one elusive item. “They do not need to hunt for what they want,” Christian states. “They do not even want to open the drawer.”
However overall growth has been slow so far, it is not for deficiency of time, energy or thought. Multiple public and private entities are chipping away at each of the many hurdles to interoperability.
In the month of November, ONCHIT issued the final version of “Connecting Health and Care for the Nation: A Shared Nationwide Interoperability Roadmap,” an agency strategy that lays out an ambitious objective of acquiring a fully interoperable national “learning health system” by the year 2024, and identifies 4 places that must be dealt to achieve that objective:
- Standards: Make better the technical standards and implementation guidance for priority data domains and connected elements.
- Financial Incentives: Quickly shift and align federal, state and commercial payment plans from fee-for-service to value-based models to stimulate the needs and demands for interoperability.
- Privacy and Security: Clarify and align federal and state privacy and protection needs that ensure interoperability.
- Consistent Business Practices: Cooperate among stakeholders to promote and align consistent plans and business practices that motivate interoperability and deal those that impede interoperability.
Since the report was issued, a variety of tasks in the industry illustrate the interest in and movement making interoperability a true reality. They involve:
- In the month of January, the College of Health Information Management Executives (CHIME) began its National Patient ID Challenge, with $1 million to the 1st individual who figures out how to precisely match sufferers with all their information without resorting to the clearest solution, a national patient ID, which federal entities are officially forbidden by Congress from creating. Entries are due by the month of April 8.
- A survey issued in the month of January by Premier, a healthcare alliance of nearly 3,600 U.S. hospitals and 120,000 other contributors disclosed that integrating information from out-of-network contributors—a key objective for interoperability attempts—is the top HIT challenge for 80% of ACOs (accountable care organizations).
- Also in the month of January, DirectTrust (an alliance of participants in the exchange of secure health messages using the Direct protocol) declared that 44 million messages were exchanged among its members in the year 2015. DirectTrust observes that this year’s message volume will top 200 million, and 2017’s could quadruple to more than 800 million, if present trends sustains. The network now involves more than a million trusted addresses.
- In the month of December, ONCHIT issued its 2016 Interoperability Standards Advisory, which not merely catalogs existing and emerging standards to meet particular interoperability requirements, but also gives implementation specifications so that vendors and agencies can incorporate the standards into their networks in a consistent way. “It is a great contribution, because before, vendors could make their own choices and contributors were stuck,” claims Joyce Sensmeier, vice president of informatics for HIMSS. “If 2 vendors have executed a standard in the similar way, the odds [of interoperability] are better.”
- Also in the month of December, Carequality (a public-private collaboration of vendors, contributors, health data exchanges and other interested parties) issued its Interoperability Framework, a set of guidelines for establishing the business agreements to enable trusted data exchange. In late January, 5 major HIT vendors were the 1st to commit to using the framework.
- HIMSS’s interoperability certification program, ConCERT, initiated about a year ago, will declare its 1st group of certified products at the upcoming HIMSS meeting in Las Vegas. It will be indicating its abilities at the Interoperability Showcase on the exhibit floor. The products must motivate both Direct secure messaging and query-based exchanges.
“I consider a tremendous amount of growth has been made, but it is been from the bottom up,” states Micky Tripathi, chief executive of the Massachusetts e-Health Collaborative, which assists agencies implement electronic health records and health data exchanges. MAeHC is serving as project manager for The Argonaut Project, a joint attempt by vendors and contributors to establish FHIR-based application programming interfaces (see sidebar).
Tripathi analyzes that various great interoperability projects, like the phone system and the ATM network, grew in regional pockets, instigated by market forces that propelled the essential technological innovations, until the market forces and the technology both reached the critical mass essential to link everyone. He appreciates that the complications of healthcare pose distinctive barriers—for starters, there are fifty different state privacy laws.
The interoperability conversation is going to flip pretty rapidly when compensation is based on value. 
“FHIR is not going to solve that issue,” he claims. “The query is what ecosystem you require to motivate these APIs. A good developer can write a complete functional app within a week, but then they try to plug it in and the system claims, “Sorry, we will not let you in!’ “
HIMSS’ Sensmeier hopes the remaining obstacles to fall soon. “The interoperability conversation is going to flip pretty rapidly when compensation is based on value,” she states. “That is going to need clinical integration like nothing we have today. If you have to indicate results from your sufferer population and show you are improving them with the care you offer, you have to have interoperability in place.”
While the technological hurdles to interoperability are being knocked over one by one, the non-technological hurdles are proving more stubborn. Until now, the business case for contributors to share data was much less attractive than the business case for not sharing.
“If we require progress in one place, it should be the incentive and motivation side,” states Julia Adler-Milstein, assistant professor in the School of Information at the University of Michigan, who recently served on an interoperability activity force assembled by the ONC’s Health IT Policy Committee.” We require a group of stakeholders saying we require solving these issues.”
Getting contributors to pay for health data exchanges has been one of those issues, but new compensation models may nudge contributors toward identifying their value. “The market has been ambivalent about HIE services, so clients have not been excited to pay for them,” Adler-Milstein states. Her recent research indicates that health data exchanges are seeking ways to offer extra value to their clients, in the form of analytics services and ways to integrate information to support value-based care.
Sometimes the simplest solution is the place to begin, and Adler-Milstein analyzes much near-term promise in vendor-based networks like Epic’s Care Everywhere. “They made it quite convenient for anyone who has Epic to turn on this functionality, and they had a take-it-or-leave-it access to governance,” she states. “Everyone who is had the option has said yes.”
Although, proprietary solutions will not solve the long-term issue, and she would like to see the vendor community try to acquire something close to plug-and-play interoperability. “We could push a lot harder on EHR vendors to work among themselves, if we truly needed to make some quick growth,” she states.
The market has been ambivalent about HIE services, so clients have not been excited to pay for them. 
The Michigan Health Information Network (MiHIN), a consortium of Michigan HIEs, has appointed to prove its value “one use case at a time,” states executive director Tim Pletcher, MD. “We consider that persons actually only do what they are paid to do or punished for not doing,” he states. To that end, the agency has chosen particular tasks, such as reporting immunization data to the state, which is needed by the government’s meaningful use incentive program, and made them convenient to do through the HIE. It is also helping contributors share admission, discharge and transfer [ADT] data, and Pletcher claims 98% of the state’s admissions can be accessed on the network.
Erica Galvez recently left her post as ONC’s interoperability portfolio manager to become the director of health data exchange at Aledade, a company headed by former National Coordinator Farzad Mostashari. Aledade serves the establishment of physician-led accountable care organizations and is presently active in 11 states. In her latest capacity, she analyzes even more clearly the business-related hurdles to full and easy information sharing. She is presently focused on making certain ADT data flows from hospitals to physicians, so they can manage care transitions.
“The difficult thing is brokering the agreement: the terms and conditions, the pricing, and how we will get the data up and running,” she states. “Once we can agree, receiving the technical nuts and bolts in place is pretty easy. It is that up-front negotiation around ‘Here is why you should let your information go, and here is how you can do it in a HIPAA-compliant manner, and here is the economical value of that data.’”
Sufferer matching, necessary for making certain contributors are retrieving data on the correct sufferer, remains a formidable issue, as CHIME has identified with its $1 million prize. IHIE’s Chuck Christian, who is also chairman of the CHIME Foundation board, recently got a personal look at the issue when he and his wife made a visit to the island of St. Lucia to celebrate their 40th wedding anniversary.
They were staying at a famous resort where guests sign for all their on-site purchases and then settle up when they leave. When he was fed up to make a purchase in the gift shop, to his astonishment, the salesperson inquired him to verify his identity with his passport. “Turns out there were more than 1 Charles Christian at the resort that week,” he states. “In a resort with merely 700 persons.”
Every day, 10,000 persons in the U.S. turn 65, and few of them inevitably have the similar name, analyzes Dean Sittig, professor of biomedical informatics at the University of Texas Health Science Center at Houston. He has done extensive research on how to stop errors in medical data, and claims misidentification of sufferers is one of the most usual and dangerous mistakes.
Most identifiers are not distinctive, or even permanent, he states. Most females change their names at least once in their lives, and one in 4 persons change their address in any given year. “Even gender is not as permanent as we thought,” he states. “We cannot have interoperability if we cannot match your information when we shift it from 1 place to another.”
