CONCLUSION
The results of several reviewed studies show that the CPs with the
highest accuracy to identify TG patients contained diagnosis codes and
another component, such as and procedural and medication codes for
claims data and key text-strings for EHR data. However, researchers have
been able to find most TG patients within their electronic healthcare
databases through diagnosis codes alone, although differences may occur
depending on the data structure of the health system utilized. These
findings support the conclusion that CPs are essential to identifying TG
patients when self-reported gender identity is not available to
understand TG population health patterns.
