ABSTRACT

PURPOSE: Combinatorial pharmacogenetic (PGx) panels intended to aid psychiatric prescribing are available to clinicians. Here we evaluated the documentation of PGx panel results and subsequent prescribing patterns within a tertiary healthcare system.

METHODS: We performed a query of psychiatry service note text in our electronic health record (EHR) using 71 predefined PGx terms. Patients who underwent combinatorial PGx testing were identified, and documentation of test results was analyzed. Prescription data following testing were examined for the frequency of prescriptions influenced by genes on the panel along with the medical specialties involved.

RESULTS: A total of 341 patients received combinatorial PGx testing, and documentation of results was found to be absent or incomplete for 198 patients (58%). The predominant method of documentation was through PDFs uploaded to the EHR’s “Media” section. Among patients with at least one year of follow-up, a large majority (194/228, 85%) received orders for medications affected by the tested genes, including 132/228 (58%) patients receiving at least one non-psychiatric medication influenced by the test results.

CONCLUSION: Results from combinatorial PGx testing were poorly documented. Medications affected by these results were often prescribed after testing, highlighting the need for discrete results and clinical decision support.
