Abstract

An untoward event took place in Australia in 2011 involving a patient whose entire peripherally inserted central catheter (PICC) migrated into his pulmonary artery. At this particular rural hospital, a small vascular access team was initially formed; however, the PICC insertion procedure was taken over by a physician intensivist and his medical residents, who learned the procedure from him during their 3-month rotations. The distal portion of the patient's PICC, attached initially to a distal catheter-stabilizing device, dislodged and was drawn into the vein. The patient's PICC, now in his pulmonary artery, was retrieved via interventional radiology and the patient experienced no serious side effects from this event. This case highlights the importance of using only highly trained personnel who are familiar with the medical supplies to insert PICCs.

Abstract

Background: Elimination of catheter-related bloodstream infections is a major focus in health care. According to the Centers for Disease Control and Prevention and the Infusion Nurses Society, the optimal time for needleless connector disinfection has not yet been empirically established.

Methods: Using experimental design and established lab procedure, a 0.5 MacFarland suspension was used to inoculate 172 needleless connectors with bacteria (Staphylococcus aureus, Staphylococcus epidermidis, and Pseudomonas aeruginosa) and allowed to dry for 18 hours. Five groups of connectors (n = 27 per group) were disinfected using 70% isopropyl alcohol with friction for 5, 8, 10, 12, and 15 seconds, and flushed with 0.5 mL nonbacteriostatic sterile normal saline onto sheep-blood agar plates for incubation at 35° C for 48 hours. Bacterial growth (1 colony) was noted on 2 negative controls; therefore, a second sample (n = 172) was tested as above using additional precautions of masking, gloving, and gowning. A third group of connectors was tested using a 0.5 MacFarland suspension containing yeast (Candida albicans).

Results: Group 1 showed significant (χ² ₄ = 37.93; P = .00) and strong (Cramér's V = 0.53; P = .00) associations between scrub time and growth status. Although not statistically significant, Groups 2 and 3 demonstrated clinically significant associations between these factors.

Conclusions: Although additional research is warranted, our study showed that disinfection times of 5 and 8 seconds were inadequate for reducing bacterial transfer. However, disinfection times of 10, 12, and 15 seconds resulted in comparable, decreased rates of bacterial migration.

Abstract

Introduction: Peripheral venous cannulas are predominantly inserted by nurses and medical practitioners. Placement and related care of such devices are one of the most frequently performed tasks by these staff members. Clinicians in training should be given ample opportunity to practice these skills before patient encounters begin.

Aims: To identify the best available evidence on the training of undergraduate clinicians in peripheral venous access.

Methods: We used an integrative literature review method that considered both experimental- and nonexperimental-design studies that addressed the issue of clinician peripheral venous access training of undergraduates. The electronic databases Medline, Embase, Ovid Nursing Database, British Nursing Index, Pre Medline, Mosby's Index, and CINAHL were searched using a predetermined search strategy. The Cochrane and Joanna Briggs databases were also searched along with the reference lists of published materials.

Results: A total of 56 articles were retrieved using the defined search strategy. There were 11 experimental-design studies and 1 nonexperimental-design study selected for final review after independent assessment for methodologic quality. Retrieved articles found disparity between actual skill and student self-evaluation. Teaching methods varied with the use of traditional task trainers and high-fidelity simulation. No method was found to be superior.

Conclusion: Skill acquisition in vascular access is an international issue and one that has been addressed in varying degrees. We identified heterogeneity in training methods that were tailored to institutional requirements and resources. Training in this skill is imperative to ensure competency before patient encounters.
