Abstract
The use of sutureless securement devices during catheterization might reduce the risk of catheter-related bloodstream infection (CRBSI) by suppressing catheter-exit infection and catheter dislodgement. However, the effectiveness of these devices in reducing CRBSI risk when securing hemodialysis catheters has not been explored. This single-center retrospective observational study examined 211 non-tunneled hemodialysis catheters (NTHCs) from 110 hemodialysis inpatients, of which 121 were secured using conventional skin sutures (Suture group) and 90 with GRIP-LOK (GRIP-LOK group). The stabilized inverse probability of treatment (SIPT)-weighting method was used to generate a new population (SIPT-weighted model) without group differences for each of the 12 predictors of CRBSI development (i.e., age, sex, dialysis history, concomitant acute kidney injury or diabetes, concurrent use of immunosuppressant drugs or aspirin, NTHC insertion site, methicillin-resistant Staphylococcus aureus, carriage, bacteremia event within 3 months before catheterization, hemoglobin level, and serum albumin titer). The effect of GRIP-LOK compared with sutures on CRBSI in the SIPT-weighted model was evaluated using univariate SIPT-weighted Cox proportional regression analysis, which showed a significant CRBSI suppression effect of GRIP-LOK compared with sutures (hazard ratio: 0.17 [95% CI 0.04–0.78], p = 0.023). GRIP-LOK affords a lower risk of CRBSI due to indwelling NTHCs than conventional securement using sutures.
Highlights
The use of sutureless securement devices during catheterization might reduce the risk of catheterrelated bloodstream infection (CRBSI) by suppressing catheter-exit infection and catheter dislodgement
In this retrospective cohort study, we examined whether using a GRIP-LOK device was more effective than skin sutures at preventing CRBSI in patients undergoing hemodialysis via non-tunneled hemodialysis catheters (NTHCs)
Catheters were secured to the skin using sutures in 121 NTHCs (57 inpatients) and a GRIP-LOK device in 90 NTHCs (59 inpatients)
Summary

In this retrospective cohort study, we examined whether using a GRIP-LOK device was more effective than skin sutures at preventing CRBSI in patients undergoing hemodialysis via non-tunneled hemodialysis catheters (NTHCs) This observation is expected to be a starting point to encourage further research to verify this effect, such as with randomized control studies, with the ultimate goal of promoting the use in clinical practice for the benefit of dialysis patients
