Summary:To identify overall and site-specific rates of nosocomial infections (NIs) during the neutropenic, as compared to the non-neutropenic stage of treatment in adult recipients of allogeneic and autologous bone marrow transplantation (BMT) and peripheral blood stem-cell transplantation (PBSCT), a prospective, 54-month study was started at the Haematological Stem Cell Transplantation Unit of the University Hospital of Freiburg, Germany. NI types were identified using modified CDC definitions. A total of 351 patients (14?256 in-patient days, 5026 neutropenic days) were investigated (316/90% allogeneic, 35/10% autologous; BMT: 119 patients, PBSCT: 234 patients). The mean length of neutropenia was 14.3 days (range: 0-66). Antimicrobial prophylaxis for allogeneic transplantation consisted of ciprofloxacin, trimethoprim/sulpha-methoxazole, fluconazole, and metronidazole. In total, 239 NIs were identified in 169 patients (48.1%), and of these 171 (71.5%) occurred during neutropenia (34.0 NIs per 1000 days at risk). The main pathogens were coagulase-negative staphylococci (36.3%), Clostridium difficile (20.4%), and enterococci (10.0%). Site-specific incidence densities during neutropenia vs non-neutropenia were: 13.9 vs 1.6 bloodstream infections (all central line-associated), 11.9 vs 1.8 pneumonias, 3.0 vs 2.9 gastroenteritis, and 1.6 vs 0.3 urinary tract infections. The greatest number of NI in BMT and PBSCT recipients is acquired during neutropenia, and multicentre surveillance programmes should focus on this.Bone Marrow Transplantation (2003) 31, 795-801. doi:10.1038/sj.bmt.1703920 [ABSTRACT FROM AUTHOR]
