Background Catheter‐related infections (CRIs) and catheter‐related bloodstream infections (CRBSIs) are among the most frequent hospital acquired infections. CRI/CRBSI studies in Scandinavian cohorts are scarce. The primary aim of this study was to investigate the CRI/CRBSI incidence and the association between potential risk factors, including the introduction of a simple hygiene insertion bundle and CRIs at a large university hospital in Sweden. Methods We retrospectively included all patients aged 12 and above who received a central venous catheter (CVC) or a central dialysis catheter during a 2‐year period, 1 year before and 1 year after the implementation of a simple hygiene insertion bundle. Microbiological data, including catheter tip cultures and blood cultures, were merged with CVC insertion data. Results A total of 1722 catheter insertions in 1428 patients were included. CRI and CRBSI incidence were 1.86/1000 and 0.62/1000 catheter days, respectively. In a multivariable regression model, the implementation of a simple hygiene insertion bundle was the independent factor most strongly associated with significantly lower CRI‐incidence (95% confidence interval [CI] of odds ratio [OR] 0.23‐0.92, P = .029). Choosing multiple lumen catheters was associated with increasing CRI‐incidence (95% CI of OR 1.11‐2.39, P = .013). Conclusion The incidence of catheter‐related infections and catheter‐related bloodstream infections in this Scandinavian cohort was low. The implementation of a simple hygiene insertion bundle seems to be an effective intervention for reducing catheter‐related infections. The use of multiple‐lumen catheters is associated with increased risk of catheter‐related infections.
