Predictive Analytics in Healthcare: A New Era of Proactive Medicine

The healthcare field, in its orientation, has long been a reaction one. It is understood to view most interventions in terms of health in terms of happening when one is unwell, or at the point of diagnosis, and not any kind of prevention of such disease at all. All of this tends to contribute towards increased expenses, delayed care, and poor outcomes through traditional reactionism. Health, meanwhile, as an industry, has been a whole transformation with technology and in data science growing at a breakneck pace. With copious volumes of information, predictive analysis, facilitated through use of machine learning, AI, and augmented processes of collecting information through, for instance, use of wearable technology, provides a proactive kind of care for one's health. Inclusion of predictive analysis in the field of healthcare brings with it the potential to cause a transformational change in a model geared towards disease management to one that actively foresees and counteracts disease even before its development. Predictive models have the potential to forecast patient outcomes, detect at-risk groups, and enable timely and wiser decision-making for medical professionals. All of this is accomplished through analysis of copious volumes of information in healthcare, including electronic health information (EHRs), genetic information, information acquired through trials, and real-time information acquired through use of wearable technology, for instance. Some of the many driving factors for predictive analysis include a growing prevalence of cases of disease that are chronic, aging populations, and an increased demand for care efficiency through cost savings in healthcare. Predictive analytics holds tremendous potential towards improvement in individual and public level health outcomes. Applications enable early prediction of disease, for instance, cardiovascular disease, diabetes, and cancers, and enable personalized therapy in terms of genotype and medical record of a patient. Predictive models serve a backbone in optimizing medical care and in enhancing patient activation, and in taking an additional step towards personalized and patient-focused care. Applications of predictive analytics in medical practice cover a range of concerns, including security and information privacy, ethics, and integration of disparate sources of information. As a potential opportunity for gain, it carries a lot of potential. The present work stands in such concerns but also in terms of necessity for continuous technology development, collaboration between medical professionals and technology providers, and empowered patients in information flow. Central concerns addressed in this book include an introduction to predictive analytics, its use in proactive care, recent technological development in bringing such innovations reality, and concerns for medical care delivery structures in utilizing predictive modality for full realization of its potential. Next, we move in the future direction predictive health will head, and with it, the critical necessity for medical professionals in putting information and proactive approaches in patient care. The purpose of present work is to present a complete picture of predictive analytics shaping the future of medicine, transforming medical care.
