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.

The Evidence for Evolution

Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Gram-negative Bacterial Protein Secretion Systems01:17

Gram-negative Bacterial Protein Secretion Systems

Gram-negative bacteria utilize sophisticated protein secretion systems to transport proteins across their double-membrane envelope into the extracellular environment or host cells. Based on their mechanism of action, these systems are classified into one-step and two-step pathways.One-Step Secretion Systems (Types I, III, IV, and VI)One-step secretion systems bypass the periplasm entirely, forming a continuous channel that spans both the inner and outer membranes:Type I Secretion System (T1SS):...

Observational Studies01:11

Observational Studies

Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Prevalence and Incidence01:08

Prevalence and Incidence

In statistical epidemiology and health sciences, two essential metrics—prevalence and incidence—are fundamental for understanding disease dynamics within a population. These measures enable public health officials, epidemiologists, and researchers to assess the burden of diseases, allocate resources effectively, and design impactful public health policies and interventions.
Prevalence indicates the proportion of individuals in a population who have a specific disease or health...

Venous Thrombosis II: Clinical Manifestations and Diagnostic Studies

The key difference between Superficial Vein Thrombosis (SVT) and Deep Vein Thrombosis (DVT) lies in their location and severity.Clinical ManifestationsSVT typically presents with localized pain, tenderness, and redness along the course of a superficial vein, often accompanied by a palpable, cord-like structure under the skin. This condition is usually less dangerous than DVT but can be uncomfortable and may lead to complications such as cellulitis or, rarely, a clot extension into the deep...
