Surveillance nationale des septicémies nosocomiales
(Hospital-wide)
|
Introduction
Blood stream infections (BSI) belong to the severe hospital infections and they are characterized by a high mortality rate. Due to their severity and their impact on the length of stay of a patient in the hospital, the Scientific Institute of Public Health (IPH) started the national surveillance of nosocomial BSI (hospital-wide) in 1992. This surveillance has been interrupted in 1996, but started again in October 1998. BSI are recorded for the whole hospital on the basis of positive blood cultures.
The surveillance of nosocomial BSI makes a distinction between primary BSI (catheter associated nosocomial BSI) and secondary nosocomial BSI (attributed to other infection).
Methodology
Since October 1992, the IPH invites all Belgian hospitals to participate on a voluntary basis to the national surveillance of nosocomial BSI (hospital-wide).
This surveillance is hospital-based so denominators (number of admissions and number of patient days) are collected for the whole hospital and optionally for the intensive care unit.
A BSI is considered as nosocomial if occurs after 48 hours stay at the hospital. BSI data are collected pour all patients with a positive haemoculture as stated on a standardized protocol.
Hospitals send their surveillance data after 3 months registration to the IPH for analysis, benchmarking and feedback.
Data handling
Data sent to the IPH are checked on their internal validity before being appended to the national database. Analyses are done at local, regional and national level.
Confidentiality
Individual hospitals’ data are treated in a strictly confidentially way. No information on the identity of patients or clinicians is transmitted. The IPH send the surveillance results only to the reporting hospital.
