Background Pilot project to standardize local laboratory data at five Indian Health Service (IHS) medical facilities by mapping laboratory test names to Logical Observation Identifier Names and Codes (LOINC). Pilot project to standardize local laboratory data at five Indian Health Service (IHS) medical facilities by mapping laboratory test names to Logical Observation Identifier Names and Codes (LOINC). An automated mapping tool was developed to assign LOINC codes. At these sites, they were able to map from 63% to 76% of the local active laboratory tests to LOINC An automated mapping tool was developed to assign LOINC codes. At these sites, they were able to map from 63% to 76% of the local active laboratory tests to LOINC Eleven percent to 27% of the tests were mapped manually. They could not assign LOINC codes to 6% to 19% of the laboratory tests due to incomplete or incorrect information about these tests. Eleven percent to 27% of the tests were mapped manually. They could not assign LOINC codes to 6% to 19% of the laboratory tests due to incomplete or incorrect information about these tests.

Proposed Updated Methodology Using VA’s Laboratory Electronic Data Interchange specimen codes associate local codes to specimen. Produce candidate matches of local unit codes to UCUM. Finally, using a IHS master LOINC file, auto-map local codes to the Common Lab Orders LOINC Value Set Version 1.1. Those codes that are not automatically mapped, will be put into a file and submitted to OIT for further investigation and possible matching through the Regenstrief’s RELMA tool.

Proposed Methodology Issues LEDI Specimen codes – are based upon a deprecated table from HL7 V2.x. LEDI Specimen codes – are based upon a deprecated table from HL7 V2.x.

Some next steps LOINC code look up – link to RELMA from IHS Lab home page. LOINC code look up – link to RELMA from IHS Lab home page.

Continuous improvement As we deploy, the master list gets better. The process is refined until it will be highly accurate. This will allow us to have a “Gold” standard for future deployments.

Continuous improvement Additional outcome is a study of the C80 top % compared to the Indian Health Population. Currently working on the design of experiment Will they be the same? Will our top 99% be the same as the general population?
