Taurolidine lock solutions

Abstract:

Background: The incidence of central venous catheter (CVC)-related bloodstream infections is high in patients requiring a long-term CVC. Therefore, infection prevention is of the utmost importance.

Aim: To provide an updated overview of randomized controlled trials (RCT) comparing the efficacy of taurolidine containing lock solutions (TL) to other lock solutions for the prevention of CVC-related bloodstream infections in all patients populations.

Methods: On 15 February 2021, PubMed, Embase and The Cochrane Library were searched for RCTs comparing the efficacy of TLs for the prevention of CVC-related bloodstream infections with other lock solutions. Exclusion criteria were non-RCTs, studies describing <10 patients and studies using TLs as treatment. Risk of bias was evaluated using the Cochrane Risk of Bias 2 tool. A random effects model was used to pool individual study incidence rate ratios (IRR). Subgroup analyses were performed based on the following factors: CVC indication, comparator lock and bacterial isolates cultured.

Findings: A total of 14 articles were included in the qualitative synthesis describing 1219 haemodialysis, total parenteral nutrition and oncology patients. The pooled IRR estimated for all patient groups together (nine studies; 918 patients) was 0.30 (CI95% 0.19-0.46), favouring the TLs. Adverse events (ten studies; 867 patients) were mild and scarce. The quality of the evidence was limited due to a high risk of bias and indirectness of evidence.

Conclusion: The use of TLs might be promising for the prevention of CVC-related bloodstream infections. Large scale RCTs are needed to draw firm conclusions on the efficacy of TLs.
