IICC aims to connect labs and clinicians

In July 2010, the Department of Health and Human Services released the final regulation defining meaningful use of electronic health records (EHRs), based on which clinicians and hospitals can qualify for incentive payments authorized by the Health Information Technology for Economic and Clinical Health Act (HITECH). The regulation, which goes into effect in January 2011, portends a change in the way clinical labs consider connectivity and their role in healthcare.

To understand the relationship between connectivity and meaningful use, be aware that the incentive payments are tied not merely to adoption of EHRs but also the more significant goal of improving the healthcare process and patient outcomes. Toward this end, the regulation defines a “menu set” of 10 objectives, out of which a provider must select five to implement by 2011-2012 to qualify. The menu-set objective to “incorporate clinical laboratory results into EHRs as structured data” and the corresponding measurement “more than 40 percent of clinical laboratory test results where results in positive/negative or numerical format are incorporated into EHRs as structured data” open the door for a more complete integration of clinical diagnostics into patient care. This challenges clinical labs to build the long-awaited bridge between the lab and the clinician.

The flow of information depends on unified communication protocols. In the U.S., the use of Health Level Seven International (HL7), a data protocol/connectivity standard used throughout the world, is required for an EHR to be certified under HITECH. HL7 has been adopted throughout the health system — but not in the clinical lab.

In the clinical lab, the American Society for Testing and Materials (ASTM) standard dominates instrument interfaces and is the prevailing data protocol today. ASTM interfaces serve the lab well but do not integrate with the rest of healthcare, which is converging toward HL7.

To address the need for standardization, the IVD Industry Connectivity Consortium (IICC) was founded in 2008 to create and encourage the adoption of a unified connectivity standard, with the goal of reducing the cost and variability of data exchange between IVD devices and health IT. IICC member organizations include major instrument manufacturers and software vendors with the support of the clinical lab community. IICC announced in March 2010 the selection of HL7 2.x as the baseline standard for next-generation laboratory connectivity.

Importantly, HL7 is not only the standard in healthcare, it also supports Logical Observation Identifiers Names and Codes (LOINC), a database to facilitate exchange and pooling of results for clinical care, outcomes management and research within the context of existing HL7. The laboratory portion of LOINC contains categories such as chemistry, hematology, serology and microbiology, as well as categories for drugs, cell counts and antibiotic susceptibilities. The clinical portion includes entries for vital signs, hemodynamics, intake/output and EKG, as well as imaging data, survey instruments and clinical observations. Not surprisingly, major healthcare systems, reference labs and public-health entities have embraced LOINC.

To build the bridge between the lab and the rest of the health system, clinical labs should become IT-conversant. And they should reach out beyond the lab — to the pharmacy, imaging and clinical departments — to take ownership and leadership in developing a patient-centric IT infrastructure. Doing so will elevate clinical diagnostics' status in healthcare. The converse will paint labs further into a corner, where their output will be nothing more than discrete analytical results that the rest of the healthcare system must find ways to interpret. And as clinicians increasingly look to the lab for more real-time information and decision support, labs will need to use standard HL7 messaging to be “interoperable” with other departments and the EHR. Labs should begin demanding that manufacturers and software vendors accelerate the migration toward HL7, which they can do by supporting and participating in groups such as IICC. In doing so, clinical diagnostic professionals will become a more effective voice for patients and a more direct contributor to improved healthcare efficiency and outcomes.
