Preventive medicine is exactly what it sounds like - it aims to prevent sickness before it happens.The ideology behind preventive medicine focuses on protecting, promoting, and maintaining health and well-being. It also aims to avert disease, disability, and death on an individual basis, as well as on a large scale in communities and populations.Preventive medicine is promoted by all physicians, though some choose to specialize in it. Physicians in this specialty use biostatistics and epidemiology, as well as a mix of medical, social, economic, and behavioural sciences. They may evaluate health services or manage health care organizations. They also study the cause of disease and injury within specific population segments.Preventive medicine is an interdisciplinary branch of medicine that focuses on the whole patient and the many factors influencing their health. It holds a broad scope, encompassing elements of socioeconomics, the role of legislation, health equity, and the disparities found in communities and certain populations.
