Objective: As optimal antibiotic therapy for bacteraemia remains unknown, different strategies have evolved. Routine practice in the University College London Hospitals intensive care unit (ICU) is to use short-course (5–6 days) monotherapy, unless specifically indicated (e.g. endocarditis, osteomyelitis). We decided to assess this approach for treating community-, hospital-, and ICU-acquired bacteraemia by monitoring clinical response, relapse rate and patient outcome.

Design: Six-month prospective observational study from February to July 2000.

Setting: Mixed medical-surgical tertiary referral ICU.

Patients: All 713 patients admitted to the ICU over the study period.

Measurements and results: In total, 102 bacteraemic episodes occurred in 84 patients. Eight (57%) of 14 community-acquired bacteraemias, 22 (79%) of 28 hospital-acquired bacteraemias, and 48 (80%) of 60 ICU-acquired bacteraemias (in 49 patients) were treated with short-course monotherapy. Compared with previous reported studies, these patients had a low rate (23.8%) of death directly attributable to the bacteraemia and a satisfactory clinical response in 72%. Of six relapses (all Gram-negative), four had received combination therapy for severe deep-seated infections. ICU-acquired multidrug-resistant Gram-negative bacteraemias (6.5%) and fungaemias (3%) were also uncommon. No patient discharged from ICU subsequently developed a new bacteraemia relapse, or any long-term complication such as osteomyelitis.

Conclusions: Our general strategy of short-course antibiotic monotherapy for treating bacteraemia in the critically ill appears to provide a satisfactory clinical response, low relapse rate and no long-term complications in a well-defined group of patients. Multicentre studies are warranted to compare short versus long course therapy, and monotherapy versus combination therapy.
