Central line-associated bloodstream infections at the multidisciplinary intensive care unit of Universitas Academic Hospital, Bloemfontein, South Africa.

Background: Central line-associated bloodstream infections (CLABSIs) are frequently encountered device-related healthcare-associated infections in critically ill patients, causing substantial morbidity, mortality and prolonged hospitalisation.

Objectives: To determine the incidence of CLABSI, median catheter dwell-time prior to developing CLABSI, as well as the causative microorganisms of CLABSI among patients admitted to the multidisciplinary intensive care unit (MICU) at Universitas Academic Hospital, Bloemfontein.

Methods: We conducted a retrospective review of medical and laboratory records of all MICU patients who had a central line placed between January and December 2018.

Results: A total of 377 patients were admitted to the MICU in 2018, of which 182 met the inclusion criteria for the present study. From the cohort of 182 patients, 16.5% (n=30) of patients presented with 32 CLABSI episodes, with two patients having had two independent episodes each. A total of 1 215 central line days were recorded, yielding a CLABSI rate of 26.3/1 000-line days. Laboratory analysis identified microorganisms in 38 blood cultures, with Gram-negative organisms (55.3%; n=21) being predominant over Gram-positive organisms (39.5%; n=15) and fungi (5.3%; n=2).

Conclusion: The incidence of CLABSI at the MICU at Universitas Academic Hospital is high. Urgent intervention with strict compliance to prevention bundles is required to reduce the high incidence of CLABSI.
