Open- vs Closed-Tip Valved Peripherally Inserted Central Catheters and Midlines: Findings from a Vascular Access Database

Infiltration and Extravasation Risk with Midline Catheters: A Narrative Literature Review

Midline catheters have recently gained popularity in clinical use, with a common reason being the reduction of central venous catheter use and central line-associated bloodstream infections. At the same time, the number of nononcology vesicant medications has increased, and midline catheters are frequently being used for infusions of vesicant medications. The Infusion Nurses Society (INS) Vesicant Task Force identified midline catheter use as a possible risk factor for extravasation and concluded that a thorough literature review was necessary. This review highlights the variations in catheter terminology and tip locations, the frequency of infiltration and extravasation in published studies, and case reports of infiltration and extravasation from midline catheters. It also examines the many clinical issues requiring evidence-based decision-making for the most appropriate type of vascular access devices. After more than 30 years of clinical practice with midline catheters and what appears to be a significant number of studies, evidence is still insufficient to answer questions about infusion of vesicant and irritant medications through midline catheters. Given the absence of consensus on tip location, inadequate evidence of clinical outcomes, and importance of patient safety, the continuous infusion of vesicants, all parenteral nutrition formulas, and infusates with extremes in pH and osmolarity should be avoided through midline catheters.

Types of peripherally inserted central catheters and the risk of unplanned removals in patients: A prospective cohort study

BACKGROUND

Peripherally inserted central catheters are widely used in clinical practice. Despite the many advantages of peripherally inserted central catheters, unplanned removals can occur owing to irreversible complications and may have adverse consequences for patients. However, the relationship between peripherally inserted central catheter type and the incidence of unplanned removal is unclear.

OBJECTIVE

To investigate the association between the type of peripherally inserted central catheter and unplanned catheter removal.

DESIGN

A multicenter prospective cohort study.

SETTINGS

Sixty hospitals located in 30 cities across seven provinces in China.

PARTICIPANTS

Three thousand two hundred and twenty-two patients aged 18 years or older with one peripherally inserted central catheter inserted for treatment were enrolled, and 3166 (98.3 %) patients with follow-up data were included in the final analysis.

METHODS

The included participants had peripherally inserted central catheters that either had a proximal valve (n = 2436) or were open-ended (n = 730). A competing risk Cox regression model was used, and both univariate and multivariate analyses were conducted. A sub-distribution hazard model was applied to test the validity of the results.

RESULTS

Of the 2436 peripherally inserted central catheters with a proximal valve and 730 that were open-ended, 272 (11.2 %) and 46 (6.3 %) were removed unplanned, respectively. The whole incidence of unplanned removal was 10.04 %; multivariate Cox regression was conducted and it was determined that unplanned removal was statistically significantly associated with the proximal valve peripherally inserted central catheter type (hazard ratio: 1.86, 95 % confidence interval: 1.28 to 2.70, p = 0.001). In patients without cancer, the risk of unplanned removal of peripherally inserted central catheters with a proximal valve was 8.14 times higher than that of open-ended peripherally inserted central catheters (p < 0.001).

CONCLUSIONS

In this study, peripherally inserted central catheters with a proximal valve had a higher risk of unplanned removals, especially in patients without cancer. The peripherally inserted central catheter type should be considered in advance, and clinical staff should take appropriate measures to prevent unplanned removals after insertion.

The Practice and Complications of Midline Catheters: A Systematic Review

OBJECTIVE

Midline catheters are considered "midway" regarding vascular access. The objective of this systematic review was to explore the current practice, dwell time, and complication rates of midline catheters.

DESIGN

Systematic review.

SETTING

Search on four databases, PubMed, CINAHL, Scopus, and Embase, were conducted for English language articles published after the year 2000.

MEASUREMENTS AND MAIN RESULTS

A total of 987 articles were identified, of which 31 manuscripts met the inclusion criteria and were selected for review. Quality assurance was performed based on the Newcastle-Ottawa score. Average dwell time and complication rates were calculated for studies involving adult patients and adjusted for sample size. This analysis included data from the placement of 18,972 midline catheters across five countries. Aside from two randomized control trials, most of the studies analyzed were cohort studies. One pediatric and two neonatal studies were included. The average dwell time was 16.3 days (n = 4,412). The adjusted mean infection rate was 0.28/1,000 catheter days, with 64% of studies not reporting any infection with midline catheter. The failure rate of midline catheters was 12.5%. Adjusted average rates of other significant complications included the following: deep vein thrombosis (4.1%), dislodgement (5.0%), occlusion (3.8%), phlebitis (3.4%), and infiltration (1.9%).

CONCLUSIONS

The dwell times and failure rates of midline catheters compare favorably against published data on other types of catheters. Their infection rates are also lower than the reported rates of central venous catheters; however, they have a higher rate of mechanical complications. Active surveillance of infections due to midline catheters is recommended. More data are needed from pediatric and neonatal populations.

Nursing Interventions to Reduce Peripherally Inserted Central Catheter Occlusion for Cancer Patients: A Systematic Review of Literature

BACKGROUND

Cancer patients are considered the most at risk of the consequences of catheter occlusion. Therefore, nursing interventions that can effectively reduce the occlusion of peripherally inserted central catheter (PICC) lines must be identified to ensure a smooth treatment.

OBJECTIVE

This study aimed to evaluate nursing interventions to minimize PICC line occlusion and make recommended measures for preventing or decreasing occlusion and abnormal extubation.

METHODS

Studies about PICC occlusion that were published up to January 2017 were searched and screened in PubMed, Web of Science, Science Direct (Elsevier), EMBASE, Cochrane Library, and Chinese databases CNKI and Wanfang. Two independent reviewers screened the literature in accordance with the inclusion and exclusion criteria, assessed the quality of the included studies, and extracted the data. Further meta-analysis was performed using RevMan 5.3.

RESULTS

Thirteen trials were included. Meta-analysis revealed that education for nurses (relative risk, 0.31; 95% confidence interval, 0.19-0.51; P < .00001) was significantly associated with PICC occlusion, whereas PICC type (relative risk, 0.60; 95% confidence interval, 0.32-1.15; P = .12) was not significantly associated with PICC occlusion. The solution to washing pipes and the PICC insertion techniques were descriptively analyzed to reach statistical significance.

CONCLUSION

This study determined the correlation of PICC occlusion with the nurses' knowledge and skills, PICC types, flushing liquid and methods, and insertion techniques.

IMPLICATIONS FOR PRACTICE

The findings of this study can serve as a guide for clinical work and for developing targeted measures to reduce occlusion.

Long Peripheral Catheters: A Retrospective Review of Major Complications

The risk of infectious and noninfectious complications associated with long peripheral catheters (LPCs) is unknown. In this retrospective study of 539 catheters, we found LPCs were often placed for the indications of difficult access and long-term antibiotics. Rates of deep vein thrombosis (1.7%) and catheter-related infection (0.6%) were low. LPCs may represent a novel and safe option for short-term venous access.

SecurAcath for Securing Peripherally Inserted Central Catheters: A NICE Medical Technology Guidance

Central venous catheters are commonly used to deliver therapies and to monitor patients, and require securing at the point of percutaneous entry to avoid dislodgement. SecurAcath is a catheter securement device designed for central venous catheters. The National Institute for Health and Care Excellence, as a part of its Medical Technologies Evaluation Programme, selected this device for evaluation and invited the manufacturer, Interrad Medical, to submit clinical and economic evidence. The King's Technology Evaluation Centre, an External Assessment Centre commissioned by the National Institute for Health and Care Excellence, independently critiqued the manufacturer's submissions. The External Assessment Centre found a lack of evidence comparing SecurAcath with alternative approaches to securement (StatLock, suturing, tape securement), with one unpublished randomised controlled trial providing the strongest evidence. The External Assessment Centre conducted a new systematic review and meta-analysis and concluded that there is some evidence indicating the non-inferiority of SecurAcath compared to StatLock. The External Assessment Centre considered the manufacturer's economic model to be appropriate but made revisions to some parameters and noted significant heterogeneity in the included studies. The revised model indicated that StatLock was more cost effective than SecurAcath for catheter indwell times of up to 5 days; however, for medium- and long-term indwell times, SecurAcath was the most cost-effective option. The National Institute for Health and Care Excellence Medical Technologies Guidance MTG 34, issued in June 2017, recommended the adoption of SecurAcath for securing peripherally inserted central catheters within the National Health Service in England.

A Review of Four Health Procedures That School Nurses May Encounter

The school nurse plays a vital role in providing care and meeting the health needs of students in the school setting. Students attend school with chronic conditions and complex medical problems such as quadriplegia, cerebral palsy, spina bifida, and muscular dystrophy. It is the responsibility of the school nurse to provide appropriate assessment, early intervention, and care for children in the school environment. The purpose of this article is to review and discuss the knowledge and skills the school nurse needs to care for students with central venous lines, gastrostomy tubes, altered urinary elimination, and tracheostomies.

Evaluating safety, efficacy, and cost-effectiveness of PICC securement by subcutaneously anchored stabilization device

Purpose

In recent years, a large variety of medical devices has become available. Every device must be efficient, safe and cost effective, but it is not enough to use it properly without considering the environment in which it will be employed. We applied this kind of analysis to subcutaneously anchored sutureless devices (SAS).

Methods

This is a one-center prospective observational study on safety, effectiveness and cost effectiveness of an SAS device (SecurAcath, Interrad) for securement of peripherally inserted central catheter (PICC) in 30 adult cancer patients with treatment expected to be >60 days.

Results

During 4963 catheter days and after 709 dressing changes (documented by 373 pictures), the use of SAS was associated with no episode of PICC dislodgement and a lower incidence of complications if compared to traditional securement devices. Insertion, management and removal of SAS were not associated with an increased pain perception by the patients. Cost effectiveness was particularly evident for long dwelling PICCs.

Conclusions

Our study suggests that SAS is a highly effective and cost-effective method for securement of medium- to long-term PICCs with expected duration longer than 30 days. The introduction of SAS had a positive impact on our healthcare organization.
