Trial of Precision Medicine in Emergency Departments (TOPMEDs)

June 8, 2026 updated by: University of Florida
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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

  • Older Adult

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  1. Adults 40 years or older presenting to a participating ED
  2. Receipt of a new order/prescription for a selected PGx medication (Appendix 1), with a duration greater than 7 days, during the current ED visit or within 30 days prior.
  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
  3. History of severe liver disease (stage Child-Pugh C) or renal disease eGFR <15 ml/min.
  4. Any medical condition that would prohibit the ability to complete the study
  5. Prisoners, wards of the state, or patients being held under the Baker Act or Marchman Act
  6. Life expectancy less than 6 months

How is the study designed?

Design Details

  • Primary Purpose: Supportive Care
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Experimental: Immediate panel-based pharmacogenetic genotyping
Subjects assigned to the immediate pharmacogenetic genotyping group will be tested and have their results both entered into their electronic health record as well as provided to them within 2-4 weeks from randomization.
Diagnostic test: Panel-based pharmacogenetic genotyping
After consent and randomization into the immediate PGx testing, participants' results will (10-14 days after randomization) go into their EHR and be returned via a laminated results card
No Intervention: Delayed panel-based pharmacogenetic genotyping
Subjects assigned to delayed panel-based pharmacogenetic genotyping will not be tested until after their participation in the study has ended (6 months after enrollment).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
ED recidivism
Time Frame: Baseline to 6 months
The primary effectiveness outcome for the trial will be ED recidivism between participants assigned to PGx testing (intervention) compared to those assigned to delayed genotyping (usual care) within 6 months. Specifically, the rate of return visits related to their prior medical problem, identified through a matching primary diagnosis code or clinical impression abstracted from the EHR.
Baseline to 6 months
Rate of Clinician review of PGx results
Time Frame: Return of Results to 6-months
The primary implementation outcome will be the rate at which clinicians review the PGx results. This will include both viewing of CDS alerts within the UF Health EHR or viewing individualized PGx recommendations routed from patient PGx results cards.
Return of Results to 6-months
