The nosocomial infection (NI) rate in German hospitals was studied in order to create reference data for comparison in hospitals where ongoing surveillance is impossible.
The study was designed as a one-day prevalence study.
Patients in 72 selected hospitals (inclusion criteria : acute care hospitals with departments for general medicine, surgery, obstetrics/gynaecology,) were examined by four external investigators (physicians trained and validated in the diagnosis of NI).
A total of 14 996 patients were studied.
The overall prevalence rate was 3.5% (CI 3.1-3.9) with a variation of 0-8.9% between hospitals.
The commonest NI were : urinary tract infection (42.1%), lower respiratory tract infection (211.6%), surgical site infections (15.8%) and primary sepsis (8.3%). The highest prevalence rate (15.3%) was found in intensive care ward patients, followed by surgery (3.8%), general medicine (3.0%) and gynaecology/obstetrics (1.4%). The infection rate varied significantly with hospital size.
A microbiology laboratory report was only available for 56.5% of patients thought to have an NI, and there were remarkable differences between hospitals with and without an on-site microbiology laboratory.
Because of this and other methodological reasons the NI prevalence rates reported here may represent the absolute minimum of nosocomially infected patients in Germany.
