Achievements of BSI hospital-wide surveillance in Belgium

Results Out of 141 acute hospitals, about 80.8 hospitals participated annually with 211.6 surveillance quarters and 5715.8 BSI episodes. From 2005 to 2009, all indicators fell BSI/1000 admissions from 7.2 to 5.6, BSI/10000 patient-days (9.3 7.8), and BSI/1000 haemocultures (2.2 1.9). Catheter-related BSI also fell (21.6 17.6%), while secondary BSI remained stable (43.5-42.8%) and BSI of unknown origin increased (34.9 39.6%). Secondary BSI main source was, by far, urinary tract infections (UTI). Two microorganisms increased over the period: Escherichia spp. by 3% and Streptococcus spp. by 2%. The intensive care units (ICU) remained the first ward at risk (21.9 to 18.3% BSI were ICU-acquired), but geriatrics rose to a second place (11.6 14.0%).
