[Agency work in intensive care : Impact of temporary contract work on patient care in intermediate care and intensive care units].

In the few available studies no evidence was found that the use of temporary workers in intensive care units (ICU) and intermediate care units (IMC) has a significant impact on patient outcomes; however, evidence was found that individual qualifications and working conditions have an influence on outcomes. Further studies should consider what ratio of permanent to temporary workers should be considered uncritical, what qualifications temporary workers should have and to what extent these can be checked.
