Use of SNOMED CTÂ® and LOINCÂ® to standardize terminology for primary care asthma electronic health records.
The burden of asthma ranks among the highest for chronic diseases. Interoperable electronic health records (EHRs) can improve the management of chronic diseases such as asthma by facilitating sharing of data between health care settings along the continuum of care. Terminology such as SNOMED CTÂ® (Systematized Nomenclature of Medicine-Clinical Terms) and LOINCÂ® (Logistical Observation Identifier Names and Codes) are prerequisites for interoperability of EHRs. We sought to determine the extent to which data elements in a validated asthma care map (ACM) are congruent with these terminologies. A certified asthma educator entered all 169 elements in the ACM into the SNOMED CTÂ® browser. Matched elements were assigned a concept name, an identification number, and classified into a hierarchy. LOINCÂ® terminology was reviewed for asthma-related pulmonary function tests (PFTs). Forty-two percent of the ACM elements were complete matches to existing SNOMED CTÂ® concepts, 24% partial matches, and 34% unmatched. Specific asthma control parameters were either complete (n = 3) or partial (n = 4) matches, but overall "asthma control" was unmatched. There were 92% complete or partial matches for PFT elements to SNOMED CTÂ® and 83% to LOINC Conclusions: The majority of ACM elements are congruent with standardized terminology, enabling EHR interoperability. Future requests for new concepts in SNOMED CTÂ® and LOINCÂ® should be pursued for asthma control parameters paramount to evidence-based practice.
