After a discussion about the study with study staff and providing informed consent, baseline data will be collected (described in more detail below), including a buccal swab or blood sample, from patients undergoing YouScript testing. Follow-up data will be collected 120 days after enrollment on all patients. Patients will be seen in the clinic or phoned (if a visit is not scheduled in 120 days ± 14 days from baseline) and queried regarding HRU (including number of hospitalizations, ER visits, provider office visits, and procedures), changes in medications, reason for changes, and adverse drug events. This data will also be abstracted from the medical record for completeness. In addition, providers utilizing YouScript will also be surveyed regarding the usefulness of YouScript in their clinical decision-making.
