🔬 Practice-Changing Findings
Evidence from RCTs and meta-analyses published in the
last 12 months.
|
The journal of vascular access (2026) - Network Meta-Analysis
Key Findings
- Taurolidine-, ethanol-, gentamicin-, and EDTA-based lock solutions reduced CLABSI more effectively than saline or heparin.
- Taurolidine-based locks had the highest probability of reducing CLABSI (SUCRA 89.1%), followed by gentamicin-based locks (82.6%) and EDTA-based locks (72.6%).
📋 Practice Implication: For patients needing long-term central access, taurolidine-based locks appear to be the leading candidate for inclusion in a prevention bundle, with antimicrobial alternatives considered according to patient-specific risks.

Annals of medicine (2025) - Meta-Analysis
Key Findings
- Antibiotic lock therapy reduced catheter-related bloodstream infections by 63% versus non-antibiotic or no-lock strategies (RR 0.37, 95% CI 0.29-0.49).
- Overall catheter-related infection incidence was also lower with antibiotic lock therapy (IRR 0.24, 95% CI 0.15-0.38), while exit-site infection, thrombosis, and mortality did not differ significantly.
📋 Practice Implication: In hemodialysis patients, antibiotic lock therapy is a strong preventive adjunct when the main clinical goal is reducing CRBSI, but it should not be expected to lower every catheter complication.

Journal of vascular and interventional radiology : JVIR (2025) - Meta-Analysis
Key Findings
- Totally implantable venous access devices reduced the risks of systemic infection, mechanical failure, and premature device removal compared with tunneled central venous catheters.
- Device type did not significantly reduce localized infection or symptomatic venous thrombosis.
📋 Practice Implication: For children receiving prolonged chemotherapy, a totally implantable device may offer a lower overall adverse-event burden, although the choice should account for access needs and the lack of demonstrated advantage for localized infection or thrombosis.
|
Seminars in dialysis (2026) - Randomized Controlled Trial
Key Findings
- Glucose chlorhexidine antimicrobial dressings reduced catheter-insertion-site infection compared with sterile dressings (15.6% vs 40.0%).
- Sterile dressings were associated with substantially increased time-dependent risks of local infection and CRBSI compared with glucose chlorhexidine antimicrobial dressings.
📋 Practice Implication: For nontunneled catheters used during CRRT, glucose chlorhexidine antimicrobial dressings can be considered to reduce insertion-site infection and CRBSI.
|
Annals of vascular surgery (2026) - Meta-Analysis
Key Findings
- Midline catheters reduced CRBSI incidence compared with PICCs (IRR 0.58, 95% CI 0.37-0.91).
- Compared with PICCs, midlines had increased incidences of catheter-related vein thrombosis (IRR 1.91), infiltration (IRR 8.41), and total complications (IRR 2.54).
📋 Practice Implication: Device selection for intravenous therapy should balance infection reduction against thrombosis and infiltration: a midline may reduce CRBSI but is not uniformly safer than a PICC.

💡
Summary
The strongest five approved candidates all meet the clinical-significance threshold of 7 or higher. Across central, dialysis, pediatric oncology, CRRT, and midline/PICC populations, the evidence supports targeted lock or dressing strategies and shows that access-device selection changes the balance of infection, thrombosis, and mechanical complications.
