Reusable tourniquets and conventional securement dressings are considered risk factors for the occurrence of reported complications and catheter-related bloodstream infections. This study&rsquo
s purpose is to assess the impact of single-use disposable tourniquets and advanced occlusive polyurethane dressings with reinforced cloth borders on peripheral intravenous catheter (PIVC)-related complications and contamination. A pre- and post-interventional prospective observational study was conducted in a cardiology ward of a tertiary hospital between April 2018 and February 2019. Overall, demographic and clinical data from 156 patients and PIVC-related outcomes were collected (n = 296) as well as PIVC tips for microbiological analysis (n = 90). In the pre-intervention phase (n = 118), complication rates of 62.1% were reported, while 44.1% of the PIVCs were contaminated (n = 34). In the post-intervention phase (n = 178), complication rates decreased to 57.3%, while contamination rates significantly decreased to 17.9% (p = 0.014
n = 56). Through a logistic regression, it was found that the use of innovative technologies reduces the chance of PIVC contamination by 79% (odds ratio (OR): 0.21
95% confidence interval (CI): 0.05&ndash
0.98
p = 0.046). Meanwhile, PIVC-related complications and fluid therapy emerged as predictors for PIVC contamination. Findings suggest that the adoption of these innovative devices in nurses&rsquo
practice contributes to the significant reduction of PIVC contamination.
