Abstract:
The aim of this study was to describe the etiology and outcome of short-term peripheral venous catheter (PVC)-related bloodstream infections (PVCRBSI) in a 25-year period (1992 to 2016) and to identify predictive factors of Gram-negative PVCRBSI. This was a prospective observational study including all episodes of PVCRBSI. A multivariate logistic regression model adjusted for calendar year was built to explore factors associated with a Gram-negative bacterial etiology. Over the study period, 711 episodes of PVCRBSI were identified. Incidence rate of PVCRBSI increased from 0.06 to 0.13 episodes/1,000 patient-days. A Gram-negative bacterial etiology was demonstrated in 162 (22.8%) episodes. There was a significant increase in the proportion of Gram-negative infections (22.6% in 1992 to 1996 versus 33.2% in 2012 to 2016). Independent predictive factors of Gram-negative PVCRBSI were the following: being in the hospital for more than 7 days with a catheter in situ for more than 3 days (adjusted odds ratio [aOR], 1.80; 95% confidence interval [CI], 1.20 to 2.69), surgery in the previous month (aOR, 2.39; 95% CI, 1.40 to 4.09), and antimicrobial treatment with beta-lactams (aOR, 1.80; 95% CI, 1.16 to 2.78). In conclusion, we reported an increase in the prevalence of Gram-negative PVCRBSI over the last 25 years. Factors associated with a Gram-negative bacterial etiology were being in the hospital for more than 7 days with a catheter in situ for more than 3 days, having undergone surgery, and having received antimicrobial treatment with beta-lactams.
Insights
Peripheral venous catheter (PVC)-related bloodstream infections (PVCRBSI) have increased, with Gram-negative bacteria becoming more prevalent. Prolonged catheter use, recent surgery, and beta-lactam antibiotics predict Gram-negative PVCRBSI.
Area of Science:
- Infectious Diseases
- Medical Microbiology
- Hospital Epidemiology
Background:
- Peripheral venous catheters (PVCs) are common medical devices.
- PVC-related bloodstream infections (PVCRBSI) pose a significant clinical challenge.
- Understanding trends and risk factors for PVCRBSI is crucial for patient safety.
Purpose of the Study:
- To analyze the etiology and outcomes of short-term PVCRBSI over 25 years (1992-2016).
- To identify predictive factors for Gram-negative bacterial etiology in PVCRBSI.
- To assess changes in PVCRBSI incidence and causative agents over time.
Main Methods:
- Prospective observational study design.
- Inclusion of all identified episodes of PVCRBSI.
- Multivariate logistic regression analysis adjusted for calendar year to identify predictive factors.
Main Results:
- 711 episodes of PVCRBSI were recorded over the 25-year period.
- The incidence of PVCRBSI increased from 0.06 to 0.13 per 1,000 patient-days.
- Gram-negative bacteria accounted for 22.8% of PVCRBSI, with a rising proportion observed.
- Independent predictors for Gram-negative PVCRBSI included prolonged hospitalization (>7 days) with catheter use (>3 days), recent surgery, and beta-lactam antibiotic treatment.
Conclusions:
- A significant increase in Gram-negative PVCRBSI prevalence was observed over 25 years.
- Prolonged catheter dwell time, recent surgery, and beta-lactam antimicrobial therapy are associated with Gram-negative PVCRBSI.
- These findings highlight the need for vigilant monitoring and targeted prevention strategies for PVCRBSI.
