TRUU-Lab: Methods for Optimizing Test Names for Understanding and Utilization

Abstract

Abstract Introduction/Objective Poor understandability of laboratory test names increases the risk for inappropriate test utilization and medical errors. Yet, human understandability has not been a major consideration in existing laboratory test names or naming guidelines. TRUU-Lab (Test Renaming for Understanding and Utilization for Laboratory Test Names) is a national initiative that now has more than 45 members representing more than 20 academic and industry organizations, the CDC, and the FDA. The goals of the initiative include: 1) Identify root causes and challenges in understanding and using laboratory test names; 2) Share resources related to potential solutions; 3) Develop consensus guidelines for laboratory test naming; 4) Establish consensus names for existing laboratory tests; and 5) Promote the adoption and implementation of consensus laboratory test names. Methods We previously addressed the first two goals of this initiative by identifying problematic test names and features of test names that contribute to misutilization. We also identified the advantages and limitations of current test naming guidelines and previous standardization efforts. This current study addresses goals 3 and 4. We developed an iterative process of guideline development. This process includes collecting feedback on consensus names to improve guidelines, which then informs the improvement of the consensus names. Results By analyzing test name characteristics, we found that the requirements for understandability vary with respect to the clinical scenario and provider background. We have used these results to design a 30-min long survey to test candidate names. The survey will be distributed through the Brand Institute, which offers expertise in pharmaceutical name and brand identity development. This pilot survey will be sent to primary care providers to assesses intuitive name preferences given a short and specific prompt. The second phase will take place in a simulated electronic medical record environment to present clinical scenarios where physicians will select an appropriate test. Conclusion We expect that results from survey studies will directly inform the development of TRUU-Lab naming guidelines, in turn permitting development of better-optimized laboratory test names. This process represents a new strategy for the intentional design of laboratory test names that are understandable and promote correct provider utilization.
