Abstract

Objectives: This review assessed the burden of catheter-related infections (CRI), existing gaps in catheter care, and prevention recommendations for catheter-related bloodstream infections (CRBSIs). The review further discusses how the emergence of coronavirus disease (COVID-19) influenced CRBSI rates and prevention strategies in the post-COVID-19 era. Methods: A targeted literature search was conducted of Embase, Ovid MEDLINE, and EBM Reviews. Where applicable, supplemental hand searches were performed to identify evidence for gaps in the targeted search results. The authors reviewed each study and selected those for inclusion based on the population, intervention, comparison, outcomes, and study design (PICOS) criteria. Relevant studies were assessed for inclusion in the present review. Results: Both "active" methods (scrubbing, flushing, and locking) and "passive" methods (disinfection caps) have consistently been shown to reduce CRBSI risk when assessed individually. These practices have markedly improved CRBSI rates over the past two decades, although there are ongoing gaps in catheter care and adherence to best practices. COVID-19 reversed the trend towards improving CRBSI rates, and persistent challenges for nurse staffing and training have resulted in a failure to return to pre-COVID-19 CRBSI rates in the current post-COVID-19 era. These challenges are further compounded by limited rigorous comparative evidence assessing the relative efficacy of individual CRBSI prevention methods. Conclusions: Improving adherence to hub disinfection, along with catheter care and maintenance protocols, is essential for the prevention of CRIs. Further, innovative approaches for simplifying protocols and "forcing function" may increase compliance with CRBSI prevention strategies. In our practice, we routinely use disinfection caps in addition to standard scrubbing and flushing, alongside increased training and monitoring procedures. Additional studies are needed to assess which individual or combination prevention strategies are most efficacious and feasible in the post-COVID-19 era.
