Insights
This network meta-analysis compares various lock solutions to prevent catheter-related bloodstream infections (CRBSI). It aims to provide a more precise summary of evidence than traditional methods for CRBSI prevention strategies.
Area of Science:
- Medical Research
- Infectious Diseases
- Clinical Trials
Background:
- Catheter-related bloodstream infection (CRBSI) is a serious complication of central venous catheters, leading to increased morbidity, mortality, and healthcare costs.
- Traditional pairwise meta-analyses have limitations in summarizing evidence when not all treatments are compared directly.
- Network meta-analysis offers a method to synthesize evidence from multiple studies, even when head-to-head comparisons are absent.
Purpose of the Study:
- To evaluate the efficacy and safety of different lock solutions for preventing CRBSI using a network meta-analysis approach.
- To provide a more comprehensive and precise summary of evidence on CRBSI prevention strategies.
- To compare various lock solutions for CRBSI prevention beyond direct head-to-head comparisons.
Main Methods:
- A systematic search of PubMed, Embase, Web of Science, and Cochrane Library for relevant randomized controlled trials (RCTs).
- Data extraction and methodological quality assessment using the Cochrane risk of bias tool by two independent reviewers.
- Network meta-analysis conducted using WinBUGS and Stata to estimate pooled direct and indirect effects of lock solutions.
Main Results:
- The primary outcome is the incidence of CRBSI.
- Secondary outcomes include exit-site infection and catheter-related thrombosis.
- Pooled direct and indirect effects for all evaluated lock solutions will be estimated.
Conclusions:
- Network meta-analysis allows for a more robust comparison of CRBSI prevention strategies than traditional methods.
- This study will provide valuable insights into the comparative effectiveness and safety of different lock solutions.
- Findings will be disseminated through an international peer-reviewed journal.
Introduction:
Catheter-related bloodstream infection (CRBSI) is a major complication after central venous catheter insertion, which is associated with significant morbidity, mortality and additional medical costs. Many lock solutions for CRBSI have been evaluated. However, using traditional pairwise meta-analyses to summarise the evidence does not allow the inclusion of data from treatments that have not been compared head to head, which could impact the precision of pooled estimates in a meta-analysis. Therefore, we evaluated the efficacy and safety of the different lock solutions for CRBSI through a network meta-analysis.
Methods And Analysis:
The primary outcome of this network meta-analysis is the CRBSI. The secondary outcomes are exit-site infection and catheter-related thrombosis. We will search the PubMed, Embase, Web of Science and the Cochrane Library databases for recent relevant meta-analysis and their reference lists to include randomised controlled trials (RCTs) that compared lock solutions for CRBSI prevention. Two individuals will independently extract data from each included RCT according to a predesigned Excel spreadsheet and will assess the methodological quality using the Cochrane risk of bias tool. We will analyse the data using WinBUGS (V.1.4.3) and Stata (V.15.0). We will also estimate the pooled direct and indirect effects for all lock solutions using the network meta-analysis.
Ethics And Dissemination:
As the present meta-analysis is performed based on previous published studies, no ethical approval and patient safety considerations are required. This study commenced on 18 January 2019, and its expected completion date is 1 December 2019. We will disseminate the results of our network meta-analysis through an international peer-reviewed journal.
