Abstract

Aim: Evaluate results of pharmacogenomics testing for participants enrolled in the Program of All-inclusive Care for the Elderly (PACE). Materials & methods: A convenience sample of 100 participants from the PHARM-GENOME-PACE study. Genetic variants were determined by pharmacogenomics testing. Drug-gene interactions (DGIs), drug-drug-gene interactions (DDGIs) and phenoconversions were interrogated from a clinical decision support system. Results: In total, 146 genetic variants, 169 DGIs and 125 DDGIs were detected. DGIs and DDGIs occurred most commonly with the CYP2D6 gene (36.1 and 39.2%, respectively). There were 280 instances of phenoconversions; majority (62.9%) affecting the CYP3A4 isoenzyme. Conclusion: Prevalence of exposures to DGIs and DDGIs among PACE participants is high. Pharmacists using aclinical decision support system can support PACE practitioners with assessing multidrug simultaneous interactions. Clinical trial registration: NCT03257605.
