What this trial studies

This study involves adults scheduled for elective surgical procedures at the University of Chicago, where blood samples will be collected for preemptive genotyping. The genotyping will identify actionable germline variants that predict drug response or toxicity risk. Results will be provided to healthcare providers through a secure web portal, enabling personalized drug-gene clinical decision support. The initial phase will include approximately 100 patients over a six-month period to evaluate the integration of pharmacogenomic data into clinical practice.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 years or older who are scheduled for elective surgical procedures at the University of Chicago.

Not a fit: Patients who are undergoing or being considered for liver or kidney transplantation or those with known active or prior leukemia may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to more personalized and effective medication management during and after surgery.

How similar studies have performed: While pharmacogenomic approaches are gaining traction, this specific integration of genotyping at the time of surgery is relatively novel and has not been extensively tested in similar contexts.
