Brief summary

The study is enrolling adults who are scheduled for either inpatient or outpatient elective surgical procedures at The University of Chicago. At pre-operative visits, 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. Genotyping results will be delivered to participating providers as patient-specific drug-gene clinical decision support summaries using a secured Web portal, the Genomic Prescribing System (GPS). Participating anesthesiologists and critical care and pain management physicians and associated providers from the Department of Anesthesia and Critical Care at the University of Chicago will be invited to receive results for their participating patients. There will be an initial 6- month "run-in" period of the study comprised of approximately 100 enrolled adults in which all patients will have pharmacogenomic results made available to providers. The run-in period will allow for process refinement and GPS delivery to be examined and optimized prior to the randomized phase After the initial run-in period, patients will be randomized to one of two arms - in the pharmacogenomic arm, providers will have access to GPS and pharmacogenomic information, whereas in the control arm, providers will not have access to GPS and patient-specific pharmacogenomic information (current standard of care).

Interventions

PROCEDURERoutine Elective Surgery- In patient or out patient elective surgery

Participants will be undergoing routine planned surgeries.

DIAGNOSTIC_TESTBlood test for genetic testing

Blood test to determine differences in genes which may affect how certain medications affect the participant. All patients will consent to collection of a blood sample for preemptive genotyping across a panel of actionable germline variants predicting drug response or toxicity risk.

OTHERDrug-genetic Profile

Profile describing drugs that may be high-risk, those that should be used with caution, or drugs that are favorable to use based on the participants genes.

Design outcomes

Primary

MeasureTime frameDescription
The frequency of Genomic Prescribing System (GPS) use by anesthesiologists and pain medicine physicians and associated providers during the perioperative period.5 yearsTo explore the feasibility and utility of implementing broad preemptive pharmacogenomic testing in the perioperative setting by determining the frequency of Genomic Prescribing System (GPS) use by anesthesiologists and pain medicine physicians and associated providers during the perioperative period.
Rate of use of high-risk drugs in perioperative setting5 yearsTo determine the rate of use high-risk drugs (red or yellow pharmacogenomic risk) in the group of patients for whom pharmacogenomic results are available compared to their rate of use (without provider knowledge of pharmacogenomic risk designation) in the control arm.

Secondary

MeasureTime frameDescription
Rate of use of favorable drugs in perioperative setting5 yearsTo determine the occurrence of specific pharmacogenomically-informed adverse drug events in both arms.
Occurrence of specific pharmacogenomically-informed adverse drug events5 yearsTo determine the occurrence of specific pharmacogenomically-informed adverse drug events in both arms.
Pharmacogenomic result availability on pain management services in both arms using a research database for each patient5 yearsTo explore the effects of pharmacogenomic result availability on pain management services in both arms.
Comparison of pain scores on a 10 point scale5 yearsTo compare pain scores between both arms.
Anesthesia and critical care providers knowledge and perceptions of prescribing decisions using a information provided in research database5 yearsTo determine anesthesia and critical care providers' knowledge and perceptions of prescribing decisions in order to develop better genomic delivery systems in the future
Differences in patient reported satisfaction using research database5 yearsTo determine whether differences in patient-reported satisfaction and adherence likelihood are observable for patients whose providers access and use pharmacogenomic information.
