Reducing CVC-Related Infection Risks After Insertion
This paper examines evidence-based strategies for reducing central venous catheter (CVC)-related bloodstream infections following insertion. Drawing on the Institute for Healthcare Improvement (IHI) care bundle and current nursing literature, the paper covers hand hygiene protocols, chlorhexidine skin antisepsis, proper hub access and disinfection, transparent dressing techniques, and appropriate nursing staffing levels. It also addresses the importance of ongoing nurse training and simulation-based education in preventing catheter-related bloodstream infections (CLABSIs). The paper emphasizes that CLABSIs are largely preventable, carry significant mortality risk and economic burden, and require coordinated, policy-supported nursing practice to eliminate.

What makes this paper effective
- Organizes prevention strategies into clearly delineated sections that mirror the IHI care bundle framework, making complex clinical guidance accessible and logical.
- Grounds every recommendation in peer-reviewed evidence, consistently linking clinical rationale to cited studies and guidelines rather than relying on assertion alone.
- Extends beyond technical protocols to address systemic factors—staffing levels and nurse education—recognizing that individual technique cannot succeed without institutional support.
Key academic technique demonstrated
The paper demonstrates synthesis-driven argument construction: rather than listing facts from individual studies, it weaves together multiple sources per claim to build cumulative evidence for each recommendation. For example, the discussion of hub disinfection integrates Gahlot et al., Saliba et al., Wu et al., and Myatra to establish both the mechanism of infection and the procedural steps to prevent it, producing a richer, more authoritative claim than any single citation could support.
Structure breakdown
The paper opens with an introduction establishing the clinical significance and economic burden of CLABSIs, then introduces the IHI care bundle as the organizing framework. Six body sections each address one prevention strategy (hand hygiene, skin antisepsis, hub access, dressing changes, staffing, and nurse training). A conclusion synthesizes the key strategies and reinforces the nurse's central role in infection prevention. This problem-to-solution structure is well suited to clinical nursing papers focused on practice improvement.
Introduction to CVC Infections and Prevention Bundles
Multiple-lumen central venous catheters (CVCs) are used to administer large amounts of intravenous fluids, blood products, and medications. In the past, they were used only in the intensive care unit; however, they are now used in all areas of health care. CVCs are inserted through a large central vein such as the subclavian vein and terminate at the junction of the superior vena cava and right atrium. In some cases, the catheter is inserted through the femoral vein and terminates in the inferior vena cava, though this is not recommended due to the increased risk of infection. Catheters terminate in large veins where rapid blood flow around the catheter tip allows fluids and medications to be quickly diluted and moved into the patient's circulation. The location and rapid bloodstream access of CVCs increase the risk of developing catheter-related bloodstream infections, also known as central line-associated bloodstream infections (CLABSIs).
Böll et al. (2021) indicate that the risks of using central lines are significant: they are a major risk factor for bloodstream infection, are associated with a 2.27-fold increased mortality risk, and drive up health care costs (Frasca et al., 2010). CLABSI costs range from $21,400 to $110,000, representing a severe and ongoing patient safety risk and a significant economic burden for health care providers (Jacob & Gaynes, 2019).
The majority of CLABSIs are preventable through evidence-based strategies available to health care professionals (Böll et al., 2021; Gupta et al., 2021). When compared to other healthcare-associated infections (HAIs), CLABSIs account for the highest number of preventable deaths. Best practice implementation could save between 5,000 and 20,000 lives annually (Taylor et al., 2015). To assist in reducing and preventing CVC infections, the Institute for Healthcare Improvement (IHI) developed a care bundle for healthcare professionals. A care bundle is a set of evidence-based measures that, when implemented together, produce better outcomes and a more significant impact than implementing individual measures alone (Gupta et al., 2021). The best practices recommended in the IHI care bundle are: hand hygiene; maximal sterile barrier precautions upon insertion; chlorhexidine skin antisepsis; optimal site selection (avoidance of the femoral vein in adults); and daily review of central line necessity with prompt removal of unnecessary lines.
Hand Hygiene
Hand hygiene is the most convenient and cost-effective strategy for preventing CLABSIs. The World Health Organization (WHO) proposed a multimodal strategy that includes five elements as an evidence-based approach for preventing HAIs (Ling et al., 2016). The five elements are: before touching a patient; before performing a clean or aseptic procedure; after exposure to body fluid; after touching a patient; and after touching the patient's surroundings (Biehl et al., 2018). These hand hygiene strategies aim to ensure that nurses keep their hands clean and do not transfer infections between patients. By using meticulous hand hygiene technique, nurses can decrease the risks of CVC-related bloodstream infections. Myatra (2019) posits that before nurses perform CVC care, they should ensure they have washed their hands using either a waterless alcohol-based product or antibacterial soap and water. A waterless alcohol-based product is sufficient if the nurse's hands are not visibly soiled and they have not been in contact with another patient. However, washing with soap and water is recommended to ensure the hands are thoroughly clean. Hand hygiene should be performed before any CVC care (Jacob & Gaynes, 2019).
There is a considerable risk of acquiring an infection during CVC insertion and maintenance care (Taylor et al., 2015). Proper hand hygiene assists in reducing the number of bacteria that come into contact with the catheter, thereby reducing the patient's risk of developing an infection. Nurses working in high-acuity environments should be educated on the importance of hand hygiene when handling or caring for a catheter. Nurses are charged with various tasks—changing medications, drawing blood, and changing dressings—and in each of these instances, the chance of bacterial infection increases with every contact with the catheter. Therefore, proper education and quality improvement programs should be implemented across health care facilities. An educational intervention in catheter care will significantly improve patient outcomes (Ling et al., 2016), and a simulation-based training program will be especially valuable for educating nurses.
