~11 min read 4 sections Health · Nursing Practice

Abstract

This paper presents a comprehensive clinical practice guideline for the safe use of Central Venous Access Devices (CVADs) in high-acuity nursing settings, accompanied by an evidence-based report explaining the rationale for each recommended practice. The guideline addresses hospital hygiene, hand hygiene, asepsis, device insertion, post-insertion maintenance, and removal procedures. The accompanying report draws on peer-reviewed research published within the past five years to justify each safe practice, with particular attention to infection prevention, proper flushing technique, dressing management, and timely device removal. Together, the guideline and report aim to reduce the incidence of central line-associated bloodstream infections and other CVAD complications.

Introduction

The proper and safe usage of Central Venous Access Devices (CVADs) is essential in nursing to mitigate the risk of complications — such as infection, embolism, or blockage — that are associated with their use (Taylor, McDonald & Tan, 2015; Ullman, Marsh, Mihala, Cooke & Rickard, 2015). Local site infection and bloodstream infection can also result from unsafe techniques associated with CVAD usage if bacteria or fungi are present at the insertion site, on the device hub, or present in hematogenous seeding (Ullman, Cooke, Mitchell et al., 2015). In order to facilitate safe usage of CVADs, it is necessary to have an up-to-date and comprehensive CVAD Clinical Practice Guideline that nurses can rely upon to prevent central line infections (post-insertion) for use in the high-acuity unit (Loveday, Wilson, Pratt et al., 2014). This paper provides a clinical practice guideline for this purpose and develops a report that explains why the points in the guideline are needed. The report is supported by the most recent research on the most effective evidence-based practices associated with CVAD complication prevention.

CVAD Clinical Practice Guideline

For Hospital Hygiene

Safe Practice 1

The hospital environment should be clean and free from clutter and unnecessary items and equipment.

Safe Practice 2

Shared pieces of equipment used for patient care should be decontaminated after each use with the appropriate products as recommended by the manufacturer.

For Hand Hygiene

Safe Practice 3

Hands should be decontaminated before every instance of direct patient contact or care, using clean or aseptic procedures, and immediately after every instance of direct patient contact or care.

Safe Practice 4

Use of protective equipment should be appropriate to the risk of transmission of microorganisms to the patient or care provider and the risk of contamination.

Safe Practice 5

Gloves should be worn when conducting invasive procedures, when there is contact with sterile sites, when using sharps, or when handling contaminated devices.

For Asepsis

Safe Practice 6

The facility should provide education to ensure that healthcare providers are able to competently execute the aseptic technique.

Safe Practice 7

The aseptic technique should be employed any time the body's natural defenses are breached.

For Inserting

Safe Practice 8

Use the appropriate CVAD for each patient and for each specific purpose: a single-lumen catheter for lipid-based solutions; a tunneled CVAD with subcutaneous port for patients requiring long-term vascular access; a peripherally inserted central catheter for medium-term access; and an antimicrobial-impregnated CVAD for adult patients needing a catheter in place for more than five consecutive days.

Safe Practice 9

Use sterile barrier precautions when inserting central venous access devices.

For Proper Maintenance

Safe Practice 10

A sterile, transparent, semi-permeable polyurethane dressing should be used to cover the intravascular insertion site.

Safe Practice 11

Transparent, semi-permeable polyurethane dressings should be changed at least every 7 days, or sooner if moisture collects under the dressing or if the dressing becomes tattered.

Safe Practice 12

Dressings used on tunneled or implanted catheter insertion sites should be replaced every 7 days until the insertion site has healed.

Safe Practice 13

Use a single-use application of 2% chlorhexidine gluconate in 70% isopropyl alcohol to clean the central catheter insertion site during dressing changes, and allow the site to air dry.

Safe Practice 14

Do not apply antimicrobial ointment to catheter insertion sites as part of routine catheter site care.

Safe Practice 15

Do not routinely replace central venous access devices to prevent catheter-related infection, as this risks introducing new infection.

Safe Practice 16

Peripheral vascular catheter insertion sites should be inspected at a minimum during each shift, and a Visual Infusion Phlebitis score should be recorded. The catheter should be removed when complications occur or as soon as it is no longer required.

Safe Practice 17

Do not use systemic anticoagulants routinely to prevent catheter-related bloodstream infection.

Safe Practice 18

Use sterile normal saline for injection to flush and lock catheter lumens that are accessed frequently.

Safe Practice 19

Do not force a flushing of the catheter, as this risks embolism.

Safe Practice 20

Use quality improvement interventions to support the appropriate use and management of CVADs and ensure their timely removal. Interventions include: protocols for device insertion and maintenance; reminders to review the continuing use or prompt the removal of intravascular devices; audit and feedback on compliance with practice guidelines; and continuing professional education.

Removal

Safe Practice 21

The patient should lie flat with the exit site below the heart to reduce the risk of air embolism.

Safe Practice 22

Obtain advice from a surgeon if the device becomes attached or knotted to veins.

Report: Rationale for Evidence-Based Safe Practices530 words

Prevention of CVAD complications post-insertion can be achieved by taking systematic steps to raise awareness among nurses of the risks associated with applying CVADs when not needed, of leaving the devices in for too long, of not monitoring their usage on a day-to-day and hour-to-hour basis, and of not documenting device usage so that a physician is made aware of its application (Crocoli, Tornesello, Pittiruti et al., 2015). Practice should be systematically upgraded to develop and implement policy procedures…

Conclusion

Much new knowledge has been obtained through evidence-based research and practice associated with CVADs and reducing the risk of complications in relation to their application. This paper has supplied a clinical practice guideline for CVAD usage and an accompanying report to explain the rationale for the guidelines and why they are recommended. First and foremost, cleanliness is critical, and proper maintenance and close attention must always be given to the CVAD to ensure that the device is not left in too long or neglected. Because numerous infections can arise from fungi or bacteria present on the skin or on the hands of nurses, it is important that all precautions be taken. As complications can arise from flushing, from inadequate covering, and from a device left in for too long, it is critical that nurses follow the recommended guidelines to reduce the risk of the CVAD becoming a problem for the patient.
