In reply: It is untrue that new recommendations for clinically indicated peripheral intravenous catheter (PIVC) replacement are based on phlebitis alone.
A Cochrane systematic review considered catheter-related bloodstream infection (BSI) data from five randomised controlled trials (4806 patients) and found no evidence for the effectiveness of routine replacement (P = 0.64).1 The largest trial (3283 patients) studied both catheter-related BSIs and all-cause BSIs, finding no disadvantage to clinically indicated PIVC removal compared with routine replacement.2 If anything, the doubling of BSI rates with routine replacement (9/1690 v 4/1593) suggested that it was the additional insertion procedures that led to increased risk of microbial entry into blood.
Replacement of PIVCs is an intervention. Interventions are tested with the least risk of bias via systematic reviews and meta-analyses. The randomised controlled trials included in the Cochrane review were prospectively registered, with data collected by research nurses, from patients in the intervention groups with those in concurrent control groups, in multiple hospitals and the home setting.2-6 In the Lancet trial, BSIs were assessed by an infectious diseases physician blind to dwell time.2 Survival analysis assessed the true risk over time per patient, not simply crude incidence per catheter.
In their letter, Collignon and colleagues present low-level evidence — retrospective data from one hospital — with no randomisation, control group, blinding or power calculations, and no information about the total number of PIVCs inserted in the hospital or their insertion and maintenance practices.
Based on the high-level evidence, practitioners should ensure that patients avoid a repeated, painful and ineffective procedure. Medical and surgical residents and trainees are busy enough without perpetuating unnecessary routine PIVC replacements.
