Innovative, effective, and socially relevant personalized medicine is currently undergoing a stellar growth trajectory. The tenets of personalized medicine rely on the treatment of individuals based on genetic, phenotypic, environmental, lifestyle, and healthcare variables. Biologically complex diseases, interindividual variations in response to drugs, the rise of integrated multimodal diagnostics, and increasing patient empowerment are some strong drivers setting the stage in favor of personalized medicine. Leading scientific journals and governmental agencies worldwide have realized the potential of personalized medicine, and they anticipate a revolution driven by individualized treatment strategies that contribute to earlier and more precise prevention, diagnosis, or treatment of diseases, leading to better patient outcomes and societal benefits. The shift in healthcare delivery toward a patient-centric care model that enables informed decision-making, encourages behavior change, and measures the outcomes most relevant to patients has reinvigorated the need for personalization in preventing and treating both chronic and acute conditions. The application of personalized medicine allows tailoring the current prescribed approach to each patient’s specific needs, helping divide behavioral, cognitive, emotional, and medical interventions across patient populations. Personalized medicine is estimated to expand globally at roughly 11% CAGR by 2024. More effective than a one-size-fits-all strategy, predictive modeling in personalized medicine could push patient outcomes like adherence, efficacy, and remission to overlap with and potentially equate those relative to placebos. This is possible because more individuals receive an effective treatment rather than one that provides little to no effect.
