Additional outcomes include, healthcare expenditure, process indicators for implementation and provider adoption of pharmacogenomics.', 'detailedDescription': 'Pre-emptive pharmacogenomic testing will be implemented in clinical sites across seven European countries (United Kingdom, The Netherlands, Austria, Greece, Slovenia, Italy and Spain). The 36-month study is split into two (19 and 18-month) time-blocks. The participating countries are randomized to start with either implementing pharmacogenomics guided prescribing or with standard of care in the first block. In the pharmacogenomics guided prescribing arm, results of the pharmacogenomic test will be incorporated in the (electronic) medical record and may be used by physicians and pharmacists to guide drug and dose selection for 39 routinely prescribed drugs, as per the Dutch Pharmacogenomics Working Group guidelines. In the standard of care arm, patients will not receive pharmacogenomic testing. After this 19-month block, the countries switch to implementing the opposite strategy and will recruit new patients for a period of 18 months.\n\nPatients are eligible for participation when they receive a first prescription for one or more of 39 drugs for which a Dutch Pharmacogenomic Working Group guideline is available (acenocoumarol, amitriptyline, aripiprazole, atomoxetine, atorvastatin, azathioprine ,capecitabine, citalopram, clomipramine, clopidogrel, codeine, doxepin, efavirenz, escitalopram, flecainide, flucloxacillin, fluorouracil, haloperidol, imipramine, irinotecan, mercaptopurine, metoprolol, nortryptiline, paroxetine, phenprocoumon, phenytoin, pimozide, propafenon, sertraline, simvastatin, tacrolimus, tamoxifen, tegafur, thioguanine, tramadol, venlafaxine, voriconazole, warfarin or zuclopenthixol). All patients will be followed for a minimum of three months and a maximum of 18 months. In total, 8,100 patients will be recruited; 4,050 will receive pharmacogenomic testing, and 4,050 will receive standard of care. Each implementation site will concentrate on, but is not limited to, recruiting patients within a specific therapeutic area. Therapeutic areas include primary care, general medicine, cardiology, oncology, psychiatry, neurology, and transplantation. It is hypothesized that implementing pharmacogenomics guided drug and dose selection will decrease incidence of clinically relevant adverse drug reactions by 30% (from 4% to 2.8% among those with actionable drug-gene interactions).'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Subject must be ≥ 18 years old\n* Subject must receive a first prescription (meaning no known prescription for this drug in the preceding 12 months) for one or more of 42 drugs, for which a Dutch Pharmacogenomic Working Group guideline is available, which is prescribed to them in routine care\n* Subject is able and willing to take part and be followed-up for at least 12 weeks\n* Subject is able to donate blood or saliva\n* Subject has signed informed consent\n* The study limit of enrolment (200 per arm, per 18-month block) for that drug has not been reached\n\nExclusion Criteria:\n\n* Subject has previous (direct-to-consumer, or clinical) genetic testing for a gene important to the drug of inclusion\n* Subject is pregnant or lactating\n* Subject has a life expectancy estimated to be less than three months by treating clinical team\n* Duration of the drug of inclusion total treatment length is planned to be less than seven consecutive days.
