The investigators have chosen the high-stakes, rapid-paced setting of inpatient medicine for this implementation study. The investigators seek to examine whether the availability of pharmacogenomic information improves prescribing.\n\nThe investigators will enroll adults at one of three institutions, The University of Chicago, University of Illinois at Chicago, and Northwestern University. During an initial (enrollment) hospital inpatient encounter, patients will be consented and a blood sample will be obtained for preemptive genotyping across a panel of actionable germline variants predicting drug response or toxicity risk. Patients will also be targeted for enrollment who are highly likely to initiate future warfarin therapy. Patients will be recruited to two primary cohorts. In the feasibility cohort, all patients will have their actionable pharmacogenomic results (with decision support) available to inpatient treating physicians for the duration of the study, once genotyping is completed, via the Genomic Prescribing System (GPS). Physicians and pharmacists will be individually approached for enrollment through a process of direct stakeholder engagement and informed consent. Participating providers will give permission for their medication decisions to be analyzed. Providers will never be instructed how to practice nor how to prescribe, and it is their choice whether or not to use GPS. GPS accession, use, and all medications prescribed throughout the admission will be passively recorded by the research team, for all patients, and an analysis of the impact of GPS results and decision-supports will be performed.\n\nFor the African American warfarin cohort, patients newly-starting warfarin will be enrolled at the time of new warfarin initiation and then randomized such that their treating physicians and pharmacists either have access to African American-specific warfarin dosing guidance via GPS, or not. The frequency of unfavorable (high-risk) scenarios related to warfarin-related clinical outcomes will be examined in each group.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'samplingMethod': 'PROBABILITY_SAMPLE', 'studyPopulation': 'Adult patients will comprise the eligible patient population of this study.
