As medicine adapts to the 21st century, new specialties arise. General surgery is seeing two new fields emerge. One is “Acute Care Surgery,” which encompasses three facets of general surgery—emergency surgery, critical care and trauma care. The other is the concept of a surgical hospitalist. That is, a surgeon works only in a hospital and has no office or private practice. The idea is similar to the medical hospitalist movement, which has existed for several years now.
