Summary
This summary is machine-generated.Healthcare professionals often skip proper disinfection of needleless connectors, increasing central-line-associated bloodstream infection (CLABSI) risk. Improving access to supplies and managing workload are key to ensuring effective CLABSI prevention practices.
Area Of Science
- Infection Control
- Patient Safety
- Healthcare Quality Improvement
Background
- Central-line-associated bloodstream infections (CLABSI) are a significant concern in healthcare settings.
- Evidence-based guidelines recommend antiseptic disinfection of needleless connectors (NCs) before central venous access device (CVAD) use to prevent CLABSI.
- Non-compliance with disinfection protocols can compromise effectiveness and increase infection risk.
Purpose Of The Study
- To observe NC disinfection practices in intensive care units (ICUs).
- To identify facilitators and barriers to best practices in NC disinfection.
- To assess compliance with recommended disinfection times and procedures.
Main Methods
- A human factors mixed-methods study was conducted in ICUs at two academic medical centers.
- Included nursing focus groups to explore perceived barriers and facilitators.
- Involved direct clinical observation of NC disinfection using CHG/IPA and IPA products.
Main Results
- Facilitators included product accessibility and lower workload; barriers included time constraints and knowledge gaps.
- Observed NC disinfection occurred in 77% of 48 access events.
- Mean scrubbing times, especially with IPA, were below recommended durations; drying time was minimal.
Conclusions
- Barriers such as limited product access, emergencies, and high workload impede effective NC disinfection.
- Suboptimal scrubbing and drying times, particularly with IPA, may elevate CLABSI risk.
- Sustained best practices require ongoing education, competency checks, improved supply management, and workload optimization.

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
The best practices for preventing healthcare-associated infections include hand hygiene, patient risk...
