[Oral antibiotics for severe infections : an update].

Antibiotic resistance, good resource management and health care costs drive us to think about our practice. In this update we take into consideration therapeutical guidelines for the most frequently encountered serious infections in a hospital setting, and respective non-inferiority studies supporting early switch to an oral form of antibiotic. This strategy generally leads to a shorter hospital stay, with the same effect in terms of mortality, relapse, complications or treatment failure. Too often still, doctors and patients believe that intravenous antibiotics only are effective enough for severe infections, whereas in many cases, oral antibiotics are as effective.
