Invasive pulmonary aspergillosis (IPA) represents ~ a major cause of morbidity and mortality in patients I with impaired function of the immune system such as in patients with acute myeloid leukaemia (AML). We investigated the in uence of the patients’ room occu- pancy and the sanitary facilities with regard to the inci- dence of IPA after reconstruction of a haematological ward. This is a retrospective cohort-control study in patients with newly diagnosed AML. Thirty ve patients were treated before and 28 patients in the time after the reconstruction works. The median time of neutropenia was 18.5 days vs. 19.5 days. Twelve patients before and 11 patients after the reconstruction developed IPA (p = 0.794). The incidence of IPA did not decrease after a reduction in the patients’ occupancy and improvement of the sanitary equipment. This study emphasises the presumed importance of optimal physical barriers, e.g. air ltration and/or antimycotic prophylaxis in high-risk patients.
