Researchers tackle physician challenge of correctly ordering laboratory tests

Passiment, Meisel and colleagues identified a number of significant problems, including the multiplicity of names and abbreviations used for a laboratory test, as well as the complexity and lack of standardized test nomenclature. As an example, they note that the commonly ordered laboratory test "brain naturetic peptide (BNP)" has a number of other names and abbreviations and looks and sounds similar to another commonly ordered test, "basic metabolic panel (BMP)." The incorrect ordering of such tests can lead to increased medical cost, physician frustration, and at worst, delayed diagnosis and treatment. This has been perceived as having a direct impact on patient safety. The AHRQ Patient Safety Network (PSNet) cited the article in the January "What's New" feature of patient safety literature, news and other resources.

"We found that attempts to standardize or establish a naming convention for laboratory tests were either short-lived or did not yield systems that were clinician or patient friendly," said Passiment.

The researchers suggest that certain technologies and programs that are familiar to many people could clarify some of the issues highlighted in this study. For example, search engines such as GOOGLE and BING help guide users to the most appropriate search results. If similar technology was employed in ordering laboratory tests, it could help guide clinicians towards identifying the appropriate tests, as well as conditions that would warrant the ordering of specific tests.

"Clinical laboratory tests lose their efficacy when clinicians are unable to quickly obtain accurate test results in a timely manner," said Meisel. "The goal is to have a system that clinicians find convenient, flexible and fast to best ensure the correct ordering and interpretation of laboratory tests."

The issues highlighted in this study will become more relevant as clinicians depend increasingly on electronic systems. "In the end these systems should be set up to mimic – as much as possible - the type of interaction a clinician would expect with a knowledgeable and helpful human being," added Meisel.
