Authors' conclusions
Medication-impregnated dressing products reduce the incidence of catheter-related BSI relative to all other dressing types. There is some evidence that CGI dressings, relative to SPU dressings, reduce catheter-related BSI for the outcomes of frequency of infection per 1000 patient days, risk of catheter tip colonisation and possibly risk of catheter-related BSI. A multiple treatment meta-analysis found that sutureless securement devices are likely to be the most effective at reducing catheter-related BSI though this is low quality evidence. Most studies were conducted in intensive care unit (ICU) settings. More, high quality research is needed regarding the relative effects of dressing and securement products for CVCs. Future research may adjust the estimates of effect for the products included in this review and is needed to assess the effectiveness of new products.

Authors' conclusions
It is not clear if any one dressing or securement device is better than any other in securing peripheral venous catheters. There is a need for further, independent high quality trials to evaluate the many traditional as well as the newer, high use products. Given the large cost differences between some different dressings and securement devices, future trials should include a robust cost-effectiveness analysis.

The authors found a four-fold increase in the rate of catheter-related blood stream infection when a polyurethane dressing was used to secure the central venous catheter. However, this research was at risk of bias and the confidence intervals were wide indicating high uncertainty around this estimate; so the true effect could be as small as 2% or as high as 17-fold. More, better quality research is needed regarding the relative effects of gauze and tape versus polyurethane dressings for central venous catheter sites.
