More than 50 percent of U.S. healthcare providers are connected through the Carequality interoperability framework, officials of The Sequoia Project said this week.

During The Sequoia Project’s annual meeting this week, one of its key initiatives, Carequality, reported significant growth since it became operational in July 2016. To date, more than 1,000 hospitals, 25,000 clinics, and 580,000 healthcare providers are connected through the Carequality interoperability framework.

Carequality is a national-level, consensus-built, common interoperability framework to enable exchange between and among health data sharing networks. It brings together electronic health record (EHR) vendors, record locator service (RLS) providers and other types of existing networks from the private sector and government, to determine technical and policy agreements to enable data to flow between and among networks and platforms.

In October 2017 alone, more than 1.7 million documents were shared among healthcare organizations through the Carequality Interoperability Framework. Officials attest that the rate of exchange is rapidly accelerating each month, as two million documents were exchanged in total for the first 12 months, and nearly as many are exchanged now monthly. With existing implementers continuing to onboard clients, and more than a half dozen implementers expected to go live in the first quarter of 2018, there will be continued growth, officials predict.

“When we first kicked off planning efforts for Carequality in 2014, we knew it was going to be big,” said Mariann Yeager, president of The Sequoia Project, said in a statement. “We had many of the biggest names in healthcare—including healthcare providers, technology vendors, pharmacies and others— committing to making Carequality work and implementing the framework once it was completed. And with today’s revelation about the rapid increase and scale of Carequality’s current operations, we’re delighted.”

DirectTrust, a nonprofit organization that supports health information exchange via the Direct message protocols, has announced continued steady growth in the number of healthcare organizations using its interoperability services during 2018.

The organization also noted an upsurge in the number of Direct message transactions, patient use, and addresses. According to year-end 2018 metrics:

  • There were nearly 274 million Direct message transactions between DirectTrust addresses in 2018, a 63-percent increase over the 2017 total of 168 million transactions. There were more than 110 million Direct messages transmitted during the fourth quarter of 2018 alone.
  • The number of patients/consumers involved using Direct increased approximately 35 percent to nearly 248,000.
  • The number of healthcare organizations served by DirectTrust accredited health information service providers (HISPs) increased 30 percent to nearly 139,000, compared with approximately 107,000 at year-end 2017.
  • The number of trusted DirectTrust addresses able to share PHI across the DirectTrust network increased 16 percent to more than 1.8 million since the end of 2017.
  • Eleven healthcare organizations joined DirectTrust during 2018, bringing the organization’s total membership to 115.

Last July, DirectTrust named former Cerner executive Scott Stuewe its new CEO to replace founding CEO Dr. David Kibbe. In a recent interview with Healthcare Informatics, Stuewe spoke about working more closely with EHR vendors and expanded opportunities for his organization’s trust framework.

He told Healthcare Informatics at the time that his organization could make more headway by engaging with the EHR (electronic health record) vendors who so far have not been very engaged with DirectTrust. “There are some gaps in features among the EHRs that frankly are the same gaps we saw in query-based exchange in CommonWell. There are usability problems; the way a given feature surfaces in one EHR is so different than another that you can’t even do the same work flow across the two systems,” Stuewe said.

Stuewe also noted that DirectTrust’s technical trust framework is about “stretching the highest security mechanism across identity-proofed endpoints,” which, he said, “is kind of a unique model.”

A recent data brief from the Office of the National Coordinator for Health IT (ONC) revealed that about four in 10 surveyed hospitals participated in more than one nationwide health information exchange network, such as Surescripts, the e-Health Exchange, DirectTrust, CommonWell, or Carequality. Surescripts was the most commonly network used; 61 percent of hospitals participated. The next highest participation rates were in DirectTrust and the e-Health Exchange; about a quarter of hospitals participated in each.

Hospitals Outline Agenda to Accelerate Interoperability

Hospitals and health systems are making progress in sharing health information, with 93 percent making records available to patients online, but collaboration across many private and public sector entities, including technology vendors and policymakers, is necessary to achieve comprehensive interoperability, according to a new report from national hospital associations.

The report reviews the current state of interoperability, which show promises but is still a patchwork system, as well as outlines current challenges and provides an agenda for steps to take to improve interoperability among health IT systems. The report was compiled by seven national hospital associations—America’s Essential Hospitals, American Hospital Association (AHA), Association of American Medical Colleges, Catholic Health Association of the United States, Children’s Hospital Association, Federation of American Hospitals and the National Association for Behavioral Healthcare.

“We see interoperability in action all around us. Mobile phones can call each other regardless of make, model, or operating system. The hospital field has made good headway, but it’s time to complete the job. We are united in calling for a truly interoperable system that allows all providers and patients to benefit from shared health records and data, leading to fully informed care decisions,” AHA President and CEO Rick Pollack said in a statement.

“For the best care today, it’s the data stupid. Quality care depends on having the right information at the right time, so our patient’s records need to be available in the hospital or wherever our patients receive care. Hospitals are joining together to support improving interoperability because it is the key to assuring the best for our patients,” Federation of American Hospitals President and CEO Chip Kahn said in a prepared statement.

The report highlights that hospitals and health systems are making progress in sharing health information, with 93 percent making records available to patients online, up from 27 percent in 2012. What’s more, 88 percent of hospitals are sharing records with ambulatory care providers outside their system, up from 37 percent in 2012. And, 87 percent of hospitals enable patients to download information from their health record, up from 16 percent in 2012.

“We are inching closer to, but still short of, the ideal of seamless interoperability. In health care, this refers to the capacity to send and receive a patient’s health information from multiple sources between different systems and locations with its integrity intact,” the report authors wrote. “The information communicated must be useful to the receiving care provider, patients and families, and result in the care decisions that are best for them. Today, interoperability is a partially-achieved aim, working well in some but not all settings.”

The report authors note that the key to leveraging health data’s full potential for improving patient care is the establishment of a framework for compatible technical and linguistic (semantic) standards adopted by all parties that “lead us to a generic, vendor-neutral data exchange platform.” “We currently lack universally agreed upon ways of sharing and using information — “rules-of-the-road” that make possible the uncorrupted transfer of patient data between differing (and often proprietary) health record systems,” the report authors wrote.

Looking at progress made to date, hospitals and health systems have invest hundreds of billions over the past decade in electronic health records (EHRs) and other IT systems that record, store and transfer patient data securely among medical professionals. In 2017 alone, hospitals and health systems invested $62 billion in these IT systems.

According to the Office of the National Coordinator for Health Information Technology (ONC), the vast majority of hospitals use multiple mechanisms to share health information, and more than half must use four or more. Furthermore, most hospitals devote significant resources to manually matching patient records, since we do not have a national patient identifier, the report states.

And, according to 2010 AHA survey data, only 16 percent of hospitals had a basic EHR system in place. By 2017, 97 percent of surveyed hospitals had adopted a certified EHR system.

What’s more, hospitals and health systems have made efforts to link via health information exchanges (HIEs), however, the report notes while HIEs do deliver on some of the promises of interoperability, the exchangeable data is often limited to a regional or statewide scale. “In addition, some HIEs cannot reliably carry out full data exchange within a health system among different source technologies, or data

 

 

exchange across health systems including ambulatory or post-acute settings,” the report authors wrote. Also, HIEs may not enable individual patients to access their data.

The report authors also outline the ongoing barriers to comprehensive interoperability. According to an AHA analysis on barriers to health data exchange and interoperability, 63 percent of respondents cited the lack of capable technology as the biggest barrier. That survey also identified difficulties matching or identifying the correct patient between systems also as additional costs to send or receive data with care settings and organizations outside their system as significant interoperability barriers as well.

“Barriers to interoperability must be addressed in order to support the level of electronic sharing of health information needed to provide the best care, engage people in their health, succeed in new models of care, and improve public health. Doing so requires collaboration across many private and public sector entities, including hospitals and health systems, technology companies, payers, consumers, and federal and state governments,” the report authors wrote.

The report also outlines “pathways” to advance interoperability with a particular focus around privacy, security, standards and infrastructure as well as industry stakeholders committing to share best practices and lessons learned.

Among the report’s recommendations, new standards are needed to overcome the significant gaps making communication difficult between systems. “For example, APIs (application programming interfaces), including those based on the FHIR (Fast Healthcare Interoperability Resources) standard, allow for more nimble approaches to accessing needed data. Health care will benefit most from use of standard, secure, non-proprietary APIs that minimize the added costs associated with proprietary solutions and gatekeeping. API access should support both patient access to information from providers and other stakeholders, and the use of trusted third-party tools to support clinical care,” the report authors wrote.

“While we have made much progress, at present, we have the incomplete outline of a national data-sharing system in place, one that lacks the agreed upon rules of the road, conformance, technical standards and standardized implementations to ensure that all HIE platforms can communicate correctly with each other,” the report authors concluded.

The report authors note that true interoperability that advances improved health care and outcomes is within reach with effective federal policies and key stakeholders doing their part. The report calls on health systems to use their procurement power to drive vendors toward compatibility in systems design and lend a voice to the development process.

EHR and IT vendors, in turn, should commit to more field testing and consistent use of standards, the report authors wrote, and avoid pricing models that create a “toll” for information sharing. Vendors also should offer alternatives to expensive, labor-intensive workarounds that drain providers’ time and energy.

HL7 Model Identifies Clinical Genomics Workflows, Use Cases

Domain Analysis Model covers pre-implantation genetic diagnosis, whole-exome sequencing, RNA sequencing and proteomics

HL7’s Clinical Genomics Work Group has published an HL7 Domain Analysis Model (DAM) to identify common workflows and use cases to facilitate scalable and interoperable data standards for the breadth of clinical genomics scenarios.

The Domain Analysis Model (DAM), which has underdone a rigorous ISO/ANSI-compatible balloting process, covers a myriad of use cases, including emerging ones such as pre-implantation genetic diagnosis, whole-exome sequencing, RNA sequencing and proteomics.

The effort “builds on the DAM Clinical Sequencing work that is already being used to design precision medicine workflows at hospitals across the country,” said Gil Alterovitz, Ph.D., an HL7 Clinical Genomics Work Group co-chair, in a prepared statement. He also serves as a Harvard professor with the Computational Health Informatics Program/Boston Children’s Hospital.

The Clinical Sequencing DAM fueled the design of FHIR Genomics, the subset of HL7’s FHIR standard designed to communicate clinical genomic information. “By extending to broader domains, it can serve as a standard going forward to aid in the design of workflows, exchange formats as well as other areas,” Alterovitz added,

The document presents narrative context and workflow diagrams to guide readers through the stages of each use case and details steps involving the various stakeholders such as patients, health care providers, laboratories and geneticists. This contextual knowledge aids in the development and implementation of software designed to interpret and communicate the relevant results in a clinical computer system, especially a patient's electronic health record.

The HL7 Clinical Genomics Work Group developed several new applications and refinements in the Domain Analysis Model beyond its original scope of clinical sequencing. One notable addition is the analysis of the common workflows for pre-implantation genetic diagnosis (PGD). For those undergoing in-vitro fertilization, advanced pre-implantation genetic screening has become increasingly popular as it avoids the implantation of embryos carrying chromosomal aneuploidies, a common cause of birth defects. Implementers can follow the workflow diagram and see the context for each transfer of information, including the types of tests performed such as blastocyst biopsy and embryo vitrification.

As the clinical utility of proteomics (detecting, quantifying and characterizing proteins) and RNA-sequencing increases, the DAM also outlines clinical and laboratory workflows to capitalize on these emerging technologies.

HL7 notes that future challenges arise from uncertainty about the specific storage location of genomic data, such as a Genomics Archive and Computer/Communication System (GACS), as well as the structure of a patient’s genomic and other omics data for access on demand, both by clinicians and laboratories. Best practices in handling such considerations are being formulated within HL7 and include international input from across the spectrum of stakeholders. In parallel, the HL7 Clinical Genomics Work Group has been preparing an implementation guide for clinical genomics around many of these use cases, to be leveraged alongside the newly published HL7 FHIR Release 4 standard.
