Sweden
In Sweden, one speciality entails both anaesthesiology and intensive care, i.e., one cannot become an anaesthetist without also becoming an intensivist and vice versa. The
Swedish Board of Health and Welfare regulates specialization for medical doctors in the country and defines the speciality of anaesthesiology and intensive care as being:
A medical doctor can enter training as a resident in anaesthesiology and intensive care after obtaining a license to practice medicine, following an 18-24 month internship. The residency program then lasts at least five years, not including the internship. See also
Residency (medicine), Sweden.
United States
After medical school there are several different routes to becoming an intensivist. One can do a three-year internal medicine residency, and then a three-year pulmonology/critical care fellowship, or a two-year critical care fellowship. Also, if starting with internal medicine, it is possible to do a different specialty fellowship entirely, such as three years of cardiology or gastroenterology, and then an additional one-year fellowship in critical care medicine. It is also possible to complete a residency first in general surgery, anaesthesiology, and emergency medicine before applying for a one- to two-year fellowship in critical care.
Role in healthcare
Intensivists most often work in the intensive care unit. These physicians oversee the majority of care of these patients and make decisions about treatment, testing, procedures, consultations, etc. Majority of the patients that are admitted to the ICU are severely ill, and these physicians are experts at managing their complex challenges including multiple organ failure, life-threatening infections, trauma victims, and more. They must work with a large number of other professionals including
