Compare the safety and efficacy of integrated securement device versus suture securement for centrally inserted central venous catheters: a prospective cohort study

The securement of centrally inserted central venous catheters is crucial for their safe use. However, a standardized approach to centrally inserted central venous catheters securement has not been established, and securement methods remain controversial. This study is aimed to compare the safety and efficacy of integrated securement device with suture securement for centrally inserted central venous catheters, analyzing the differences in the incidence rates of catheter-related complications between the two methods, thereby providing evidence to inform clinical decision-making regarding centrally inserted central venous catheter securement strategies. From May to June 2025, 271 hospitalized patients with indwelling centrally inserted central venous catheters at a tertiary hospital in Zhejiang, China, were enrolled in this study. Demographic characteristics and catheter insertion details were collected for all participants on the day of catheter placement. Comfort scores were assessed within 48-72 h post-insertion, and patients were monitored daily until catheter removal for complications including catheter dislodgement (complete or partial), catheter-associated skin injury, and catheter-related bloodstream infection. Chi-square tests and Mann-Whitney U test were used, as appropriate, to compare complication rates between patients managed with the two different securement methods. The enrolled patients had a mean age of 63.46 ± 14.13 years, with a slightly higher proportion of males (57.6%) than females. The majority of catheters were placed in surgical patients (84.5%), with double-lumen catheters predominating (93.4%). Right-sided insertion was the most common approach(97.8%). The mean catheter dwell time was 9.01 ± 4.62 days. No significant differences were observed between the suture cohort and the integrated securement device cohort regarding complete catheter dislodgement, partial catheter dislodgement, or catheter-associated skin injury. Neither cohort experienced catheter-related bloodstream infections. However, the integrated securement device cohort demonstrated higher comfort scores and longer average maintenance intervals compared to the suture cohort, with both differences being statistically significant. The integrated securement device could be suggested as a "safe alternative" to suture securement for centrally inserted central venous catheters stabilization, and simultaneously improves patient comfort, extends maintenance intervals, may reduces nursing workload.
