Epidemiology of Trauma
According to the principles of medicine, trauma is a “disease” rather than an injury and, as such, is no different from malaria, heart disease, or cancer. It has degrees of severity and morbidity/mortality statistics just like other diseases. It is important to understand the epidemiology of trauma as it applies to different populations of people.
There is descriptive epidemiology, which looks at the distribution of the disease over time, place, and over different subgroups of people. There is also analytical epidemiology, which looks at the causation of the trauma/disease. The environment can be a physical one or a sociocultural one. How these factors interact determines the epidemiology of trauma. Knowing these things can help public policy and laws designed to protect people from injury secondary to trauma.
