Implementation of Pre-emptive Pharmacogenomics Testing in Singapore-based Private Hospital Institutions (IMPT Study)

Pre-emptive genotyping provides relevant genomic data to physicians to facilitate prescribing and to facilitate checking of prescriptions by pharmacists to ensure drug safety and efficacy. This essential information should be incorporated into electronic healthcare systems and should be readily available. The effectiveness of pre-emptive genotyping to reduce adverse drug reactions (ADRs) is unknown in Singapore. Hence, this study is designed to evaluate whether it is feasible to implement large scale pre-emptive genotyping program at a hospital in Singapore and aim to integrate genomic medicine into clinical practice to improve drug safety and efficacy.

This study involves the testing of feasibility of pharmacogenomic genotyping in hospitals whereby our pharmacogenomics panel tests for 5 genes (CYP2D6, CYP2C9, CYP2C19, SLCO1B1 and HLA-B*58:01) which influences patient's response to more than 165 medications. Reports will be generated for all drugs that have been reported to be in CPIC Level A/B of association with the genes/haplotypes. The patients who are given these tests for free are recommended due to having experienced at least one of the diseases in our list or is at a risk of developing them.
