Krankenhaushygiene - Ausbruchmanagement bei nosokomialen Infektionen

Abstract

According to §6, section 3 of the German Protection against Infections Act [Infektionsschutzgesetz (IfSG)] an outbreak is defined as the occurrence in large numbers of nosocomial infections for which an epidemiological relationship is probable or can be assumed. About 2-10% of nosocomial infections in hospitals (about 5% in intensive care wards) occur within the framework of an outbreak. The heaped occurrence of nosocomial infections can be declared according to the prescribed surveillance of nosocomial infections (§23 IfSG) when, in the course of this assessment, a statistically significant increase in the rate of infections becomes apparent. On the other hand, the occurrence of an outbreak can also be recognized through the vigilance of all involved personnel and a general sensibilization towards this subject. The names of patients involved in outbreaks need not be reported to the responsible health authorities. As a consequence of the report the health authorities become involved in the investigation to determine the cause and its elimination, and to provide support and advice. The outbreak management should be oriented on the respective recommendations of the Robert Koch Institute.
