Study Details

Brief summary:

(a) To explore the feasibility and utility of implementing broad preemptive pharmacogenomic result delivery in the inpatient setting across multiple institutions specifically with the goal of incorporating minority-specific pharmacogenomic information; (b) To determine whether clinical outcomes for the drug warfarin are improved in African Americans through the availability of pharmacogenomics-based dosing guidance at the point-of-care.

Interventions and Outcome Measures

Arms

Overall Pharmacogenomics

All patients who consent to participation will be preemptively genotyped, at no cost to the patient nor provider. A portion of the enrolled patients will be specifically recruited for the usual care arm (no study-specific PGx information available to providers for these patients). Note that patients who are randomized to the Control Arm will be genotyped, but their results will be withheld (not available via GPS) for at least 90 days. For the warfarin sub-study, treating providers caring for patients assigned to both arms are permitted to dose warfarin according to their own discretion and best practices. In either arm of the study, providers may utilize any available other tools or decision-supports for guiding warfarin dosing, including pharmacy assistance.

NOTE: The purpose of the study is to observe if physicians/pharmacists use the genotyped information to determine prescription habits.

Warfarin Sub-Study

All patients who consent to participation will be preemptively genotyped, at no cost to the patient nor provider. A portion of the enrolled patients will be specifically recruited for the warfarin sub-study, in which patients will be randomized in 1:1 fashion to the pharmacogenomics arm of the study. Note that patients who are randomized to the Control Arm will be genotyped, but their results will be withheld (not available via GPS) for at least 90 days. For the warfarin sub-study, treating providers caring for patients assigned to both arms are permitted to dose warfarin according to their own discretion and best practices. In either arm of the study, providers may utilize any available other tools or decision-supports for guiding warfarin dosing, including pharmacy assistance.

NOTE: Warfarin is prescribed as a standard of care drug. The purpose of the study is to observe if physicians/pharmacists use the genotyped information to determine prescription habits.

Primary outcome measure

  • Frequency of Geonomic Prescribing System (GPS) use by physicians and pharmacists [ Time Frame: Up to 5 years ]
  • Number of improved clinical outcomes [ Time Frame: Up to 5 years ]
