Overview

The objectives of this study are to (1) test the feasibility of the clinical implementation of preemptive pharmacogenetic (PGx) testing in the emergency department (ED) and (2) determine if PGx testing (with appropriate decision support) decreases ED return visits and hospitalizations. We will conduct a randomized, controlled, pragmatic clinical trial assessing both the real-world effectiveness as well as implementation outcomes using a targeted PGx testing panel in several UF Health EDs.

3. Documentation of at least 2 prior ED or urgent care visits within the past 12 months

Exclusion Criteria:

1. Prior clinical pharmacogenetic test results within the EHR for genes relevant for this study (Appendix 1).
2. History of hepatic or renal transplant
