Abstract:
Background: Peripheral intravenous catheters (PIVCs) contribute substantially to the global burden of infections. This systematic review assessed 24 infection prevention and control (IPC) interventions to prevent PIVC-associated infections and other complications.
Methods: We searched Ovid MEDLINE, Embase, Cochrane Library, WHO Global Index Medicus, CINAHL and reference lists for controlled studies, from January 1, 1980-March 16, 2023. We dually selected studies, assessed risk of bias, extracted data, and rated the certainty of evidence (COE). For outcomes with three or more trials, we conducted Bayesian random-effects meta-analyses.
Results: 105 studies met our prespecified eligibility criteria, addressing 16 of the 24 research questions; no studies were identified for eight research questions.Based on findings of low to high COE, wearing gloves reduced the risk for overall adverse events related to insertion compared to no gloves (one non-randomised controlled trial [RCT]; adjusted risk ratio [RR]: 0.52, 95% confidence interval 0.33-0.85), and catheter removal based on defined schedules potentially resulted in a lower phlebitis/thrombophlebitis incidence (10 RCTs; RR: 0.74, 95% credible interval 0.49-1.01) compared to clinically indicated removal in adults. In neonates, chlorhexidine reduced the phlebitis score compared to non-chlorhexidine-containing disinfection (one RCT; 0.14 versus 0.68, p = 0.003). No statistically significant differences were found for other measures.
Conclusions: Despite their frequent use and concern about PIVC-associated complications, this review underscores the urgent need for more high-quality studies on effective IPC methods regarding safe PIVC management. In the absence of valid evidence, adherence to standard precaution measures and documentation remain the most important principles to curb PIVC complications.
