Sustained Low Incidence Rates of Central Line-Associated Blood Stream Infections in the Intensive Care Unit

BACKGROUND: Central line-associated bloodstream infection (CLABSI) is an important cause of increased morbidity and mortality in ICUs. The occurrence of CLABSI in significantly higher in developing countries and contributes to the burden of healthcare-associated infections. METHODS: This prospective study was carried out from January 2016 to December 2019 in the intensive care unit at King Faisal Medical Complex in Taif, Saudi Arabia. The Society for Healthcare Epidemiology of America/Infectious Diseases Society of America (SHEA/IDSA) recommendations were introduced and implemented during 2017–2019. In the post-intervention period, observation of hand hygiene, CLABSI bundle compliance, and benchmarking of CLABSI rates were carried out. RESULTS: The CLABSI incidence rate was 1.12/1,000 central-line days, with a 0.51 utilization ratio in the pre-intervention period. This dropped to 0.46/1,000 central line days with a 0.44 utilization ratio in the post-intervention period. This reduction was also confirmed in benchmarking with National Healthcare Safety Network (NHSN) (50th–75th) percentile pre-intervention vs (25th–50th) percentile post-intervention. Institutional risk assessment revealed a formal educational program as a potential need for improvement. The CLABSIs were caused predominantly by multidrug-resistant Klebsiella pneumoniae. CONCLUSION: We observed a reduction and sustained low incidence rate of CLABSI benchmarking to NHSN for 3 years after implementation of the basic SHEA/IDSA recommendations.
