Vessel health and preservation (Part 1): a new evidence-based approach to vascular access selection and management

Abandonment of paediatric peripheral intravenous catheter insertion in the emergency department: A retrospective cohort study

AIM

Children and their families have reported peripheral intravenous catheter (PIVC) insertion as the most stressful part of their emergency department (ED) encounter, with some enduring multiple attempts without a successful insertion. The purpose of this study was to identify factors associated with abandonment of paediatric PIVC insertion.

METHODS

A retrospective cohort study was conducted at the Gold Coast University Hospital. All patients 16 years of age and younger, presented in 2019 with a PIVC insertion attempted in the ED were eligible. The electronic medical records were screened by two reviewers to identify those who required a PIVC insertion. Logistic regression analysis was performed to assess variables associated with PIVC insertion abandonment.

RESULTS

Of 6394 records screened, 2401 (8.3%) had a PIVC insertion attempted, with 99 (4.1%) being abandoned. Age <12 months was the strongest predictor of PIVC abandonment at a rate of 11.3% (38/336), with a >10-fold increased risk for infants less than 3 months old and 3-12 months old; adjusted odds ratio (95% confidence interval) 12.4 (5.1-30.2) and 14.8 (5.8-37.4), respectively. Indications of 'infection' or 'rehydration' were associated with a decreased likelihood of abandonment when compared to 'investigation only' in multivariate modelling (odds ratio (95% confidence interval): 0.181 (0.099-0.332) and 0.262 (0.100-0.686), respectively).

CONCLUSIONS

This study suggests the rate of PIVC insertion abandonment in children is relatively infrequent. However, more than one in 10 children aged <12 months had PIVC attempts without successful insertion. PIVC abandonment was less likely when there was an indication that necessitated PIVC insertion, such as a serious bacterial infection.

Vascular access device selection: Optimizing patient outcomes - Part 1

ABSTRACT

A systematic evaluation of vascular access device (VAD) selection incorporates patient, device, and infusate characteristics to ensure optimal device placement. This article explores VAD selection from the perspective of vessel health and preservation and describes VAD selection options and indications, VAD-related complications, and strategies to reduce those complications.

Perforated intravenous catheter design is acceptable for the administration of contrast-enhanced computed tomography administration in cancer patients: Results of a pilot randomised controlled trial

BACKGROUND

Optimising first time success of peripheral intravenous catheter (PIVC) insertion and reducing intravenous (IV) complications in cancer patients undergoing contrast-enhanced computed tomography (CT) is vital to ensure vascular access preservation and diagnostic accuracy. The aim of this study was to test the feasibility of a randomised controlled trial (RCT) evaluating a novel perforated PIVC compared to a standard PIVC.

METHODS

A single centre, parallel-group, pilot RCT was conducted between March and May 2020. Adult participants diagnosed with cancer were randomised to a non-perforated PIVC (standard care) or a PIVC with a novel perforated design (intervention) for the administration of IV contrast. There were two primary outcomes: (1) feasibility of an adequately powered RCT with pre-established criteria; and (2) all-cause PIVC failure. Secondary outcomes included: first insertion success, modes of PIVC failure, dwell time, contrast injection parameters (volume and injection rate), contrast enhancement, radiographer satisfaction and adverse events.

RESULTS

Feasibility outcomes were met, except for eligibility (⩾90%) and recruitment (⩾90%). In total, 166 participants were screened, 128 (77%) were eligible and of these 101/128 (79%) were randomised; 50 to standard care and 51 to intervention. First time insertion rate was 94% (47/50) in standard care and 90% (46/50) in intervention. The median dwell time was 37 minutes (interquartile range (IQR): 25-55) in standard care and 35 minutes (IQR: 25-60) in the intervention group. There was one PIVC failure, a contrast media extravasation, in the intervention group (1/51; 2%). The desired contrast injection rate was not achieved in 4/101 (4%) of participants; two from each group. Radiographers were satisfied with the contrast flow rate.

CONCLUSIONS

This pilot RCT suggests perforated PIVCs provide expected flow rate, with no evidence of differences in contrast enhancement to non-perforated PIVCs. The feasibility of conducting a larger powered RCT was demonstrated.

Vascular access devices for prolonged intravenous therapy regimens in people diagnosed with cancer

OBJECTIVES

This is a protocol for a Cochrane Review (intervention). The objectives are as follows: To assess the relative effectiveness and vascular access device (VAD)-related complications of VADs in people requiring prolonged systemic anti-cancer treatment.

Effects of ultrasound with an automatic vessel detection system using artificial intelligence on the selection of puncture points among ultrasound beginner clinical nurses

BACKGROUND

Ultrasound guidance increases the success rate of peripheral intravenous catheter placement. However, the longer time required to obtain ultrasound-guided access poses difficulties for ultrasound beginners. Notably, interpretation of ultrasonographic images is considered as one of the main reasons of difficulty in using ultrasound for catheter placement. Therefore, an automatic vessel detection system (AVDS) using artificial intelligence was developed. This study aimed to investigate the effectiveness of AVDS for ultrasound beginners in selecting puncture points and determine suitable users for this system.

METHODS

In this crossover experiment involving the use of ultrasound with and without AVDS, we enrolled 10 clinical nurses, including 5 with some experience in peripheral intravenous catheterization using ultrasound-aided methods (categorized as ultrasound beginners) and 5 with no experience in ultrasound and less experience in peripheral intravenous catheterization using conventional methods (categorized as inexperienced). These participants chose two puncture points (those with the largest and second largest diameter) as ideal in each forearm of a healthy volunteer. The results of this study were the time required for the selection of puncture points and the vein diameter of the selected points.

RESULTS

Among ultrasound beginners, the time required for puncture point selection in the right forearm second candidate vein with a small diameter (<3 mm) was significantly shorter when using ultrasound with AVDS than when using it without AVDS (mean, 87 vs 247 s). Among inexperienced nurses, no significant difference in the time required for all puncture point selections was found between the use of ultrasound with and without AVDS. In the vein diameter, significant difference was shown only in the absolute difference at left second candidate among inexperienced participants.

CONCLUSION

Ultrasonography beginners needed less time to select the puncture points in a small diameter vein using ultrasound with AVDS than without AVDS.

An mHealth application for chronic vascular access: Consumer led co-creation

PURPOSE

Children with chronic and complex health conditions frequently need intravenous devices. The current approach to intravenous device selection, insertion, and monitoring is inconsistent, and healthcare consumers are often negatively affected by siloed health information, and poor future planning. Despite child- and family-centred care being recognised as a pillar of paediatric nursing care, limited implementation for vascular access device planning and management is evident.

DESIGN AND METHODS

To address this, we conducted a multi-phased approach to co-create, then evaluate, a mobile health (mHealth) application: IV Passport. Co-creation involved a prioritisation survey, followed by a Passport advisory panel consensus meeting. Following confirmation of the required content and features of the Passport, the mHealth application was designed and content validation achieved via survey.

RESULTS

The prioritisation survey yielded recommendations for seven features (e.g., graphical presentations of current/past devices). Content for nine device types (e.g., totally implanted ports) was suggested, each with 10 related items (e.g., insertion site). Content items for device-associated complications, future vascular access plans, and educational resources were also suggested. Following design, the application was released through Apple and Android platforms; and adapted to a paper version. Content validation was established; 100% strongly agreed the application was easy to use; 80% agreed/strongly agreed that they would recommend the Passport to others.

CONCLUSION

IV Passport embodies effective child- and family-centred care through consumer co-creation to empower patients and families manage vascular access devices.

PRACTICE IMPLICATIONS

IV Passport remains active; and can be utilised across many healthcare settings and patient populations.

Vascular access device type for systemic anti-cancer therapies in cancer patients: A scoping review

BACKGROUND

Patients with cancer can expect to receive numerous invasive vascular access procedures for intravenous therapy and clinical diagnostics. Due to the increased incidence and prevalence of cancer globally there will be significantly more people who require first-line intravenous chemotherapy over the next ten years.

METHODS

Our objective was to determine the types of evidence that exist for the vascular access device (VAD) type for the delivery of systemic anti-cancer therapy (SACT) in cancer patients. We used JBI scoping review methodology to identify the types of VADs used for SACT and with a specific search strategy included articles from 2012-2022 published in the English language. We identify (i) type of VADs used for SACT delivery (ii) the type of insertion and post-insertion complications (iii) the geographical location and clinical environment (iv) and whether VAD choice impacts on quality of life (QOL). Findings were presented using the PAGER framework.

MAIN FINDINGS

Our search strategy identified 10,390 titles, of these, 5318 duplicates were removed. The remaining 5072 sources were screened for eligibility, 240 articles met the inclusion criteria. The most common design include retrospective study designs (n = 91) followed by prospective study designs (n = 31). We found 28 interventional studies with 21 registered in a clinical trial registry and identified no core outcome sets papers specific to VAD for SACT. The most prevalent publications were those that featured two or more VAD types (n = 70), followed by tunnelled intravenous VADs (n = 67). Of 38 unique complications identified, the most frequent catheter related complication was catheter related thrombosis (n = 178, 74%), followed by infection (n = 170, 71%). The county where the most publications originated from was China (n = 62) with one randomized controlled multicenter study from a comprehensive cancer centre. Of the thirty three studies that included QOL we found 4 which reported on body image. No QOL measurement tools specific to the process of SACT administration via VAD are available INTERPRETATION: Our findings suggest a systematic review and meta-analysis of VAD use for intravenous SACT can be considered. However, the development of a core outcome set for SACT should be prioritised. Funding for high quality programs of research for VAD in cancer are needed. Comprehensive cancer centres should lead this research agenda.

A pilot randomized controlled trial of securement bundles to reduce peripheral intravenous catheter failure

BACKGROUND

Peripheral intravenous catheters (PIVCs) are ubiquitous in acute care settings however failure rates are unacceptably high, with around half failing before prescribed treatment is complete. The most effective dressing and securement option to prolong PIVC longevity is unclear.

OBJECTIVES

To determine feasibility of conducting a definitive randomized controlled trial (RCT) investigating evidence-based securement bundles (medical adhesive tapes and supplementary securement products) to reduce PIVC failure.

METHODS

In this pilot non-masked 3-group RCT, adults requiring a PIVC for >24 hrs were randomized to Standard care (bordered polyurethane dressing plus non-sterile tape over extension tubing), Securement Bundle 1 (two sterile tape strips over PIVC hub plus Standard care) or Securement Bundle 2 (Bundle 1 plus tubular bandage) with allocation concealed until study entry.

EXCLUSIONS

laboratory-confirmed positive blood culture, current/high-risk of skin tear, or study product allergy.

PRIMARY OUTCOME

feasibility (eligibility, recruitment, retention, protocol fidelity, participant/staff satisfaction).

SECONDARY OUTCOMES

PIVC failure, PIVC dwell time, adverse skin events, PIVC colonization and cost.

RESULTS

Of 109 randomized participants, 104 were included in final analyses. Feasibility outcomes were met, except eligibility criterion (79%). Absolute PIVC failure was 38.2% (13/34) for Bundle 2, 25% (9/36) for Bundle 1 and 23.5% (8/34) for Standard care. Incidence rate ratio for PIVC failure/1000 catheter days, compared to Standard care, was 1.1 (95% confidence interval [CI] 0.4-2.7) and 2.1 (95% CI 0.9-5.1) for Bundles 1 and 2, respectively.

CONCLUSIONS

A large RCT testing securement bundles is feasible, with adjustment to screening processes. Innovative dressing and securement solutions are needed to reduce unacceptable PIVC failure rates. Trial registration ACTRN12619000026123.

Safety and efficacy of midline catheters versus peripheral intravenous catheters: A pilot randomized controlled trial

BACKGROUND

Despite pervasive need for peripheral intravenous catheters, insertion is often difficult, and approximately two thirds fail prematurely. Midline catheters are an alternative long peripheral catheter, inserted in the upper arm, ideal for patients with difficult access.

AIM

The aim of this study is to test feasibility of the protocol and compare the efficacy and safety of midline catheters to peripheral intravenous catheters.

DESIGN

A parallel-group, pilot randomized controlled trial of adult medical/surgical hospitalized patients, from a single Australian referral hospital.

METHODS

Participants with difficult vascular access (≤2 palpable veins) and/or anticipated ≥5 days of peripherally compatible intravenous therapy were recruited between May 2019 and March 2020. Participants were randomized to (1) peripheral intravenous catheter or (2) midline catheter. Primary feasibility outcome measured eligibility, recruitment, protocol adherence, retention and attrition. Primary clinical outcomes measured device insertion failure and post-insertion failure.

RESULTS

In total, n = 143 participants (71 peripheral intravenous catheters and 72 midline catheters) were recruited; n = 139 were analysed. Most feasibility criteria were met. Peripheral intravenous catheters had shorter functional dwell time, with higher incidence of post-insertion failure compared to midline catheters.

CONCLUSION

Midline catheters appear to be superior for patients with difficult vascular access or receiving prolonged intravenous therapy; a large, multi-centre trial to confirm findings is feasible.

Barriers to and attitudes towards the use of safety engineered devices for paediatric cannulation in emergency care

This article describes a report of the attitudes towards and barriers to the use of safety cannulas in paediatric patients. The evaluation was prompted by a lack of engagement from both doctors and nurses who continued to use non-safety-engineered devices (non-SEDs) after safety-engineered devices (SEDs) were introduced into a paediatric emergency department (ED). A survey was conducted among doctors and nurses working in the paediatric ED with questions focusing on the participants' clinical experience, views on safety, access to training and device preference, providing both quantitative and qualitative data. The findings highlighted several issues, including a difference in opinion between professional groups towards safe sharps. Significant differences in access to training and education between doctors and nurses were also identified; including those with up-to-date training appearing more likely to use a SED than those without. Recommendations including strategies for improving compliance have been proposed, with a plan to conduct a clinical audit to measure compliance at a later date.

Ultrasound for Pediatric Peripheral Intravenous Catheter Insertion: A Systematic Review

BACKGROUND AND OBJECTIVES

Establishing peripheral intravenous catheter (PIVC) access in infants and children is a common procedure but can be technically difficult. The primary objective was to determine the effect ultrasound had on first attempt PIVC insertion success rates in the pediatric population. Secondary objectives included overall success rates and subgroups analyses.

METHODS

A systematic review of articles using Medline, Embase, CENTRAL, World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov. Randomized trials evaluating ultrasound-guided PIVC insertion against the landmark approach in pediatric patients who reported at least 1 outcome of success rate (first attempt or overall) were included. Methodological quality of the literature was assessed using the Revised Cochrane risk-of-bias tool for randomized trials. A meta-analysis using a random-effects model was performed.

RESULTS

Nine studies with 1350 patients, from a total of 1033 studies, were included for analysis. Ultrasound showed a statistically significant improvement in PIVC insertion success on first attempt in 5 of 8 studies, with an overall success rate of 78% in the ultrasound group and 66% in the control group. The secondary outcome of overall success was improved by ultrasound in studies that allowed ≥3 attempts (pooled OR 3.57, 95% CI 2.05 to 6.21, P < .001, I2 = 0.0%).

CONCLUSIONS

This systematic review suggested that ultrasound improves pediatric PIVC first pass and overall success rates. Subgroup analysis showed improvement in PIVC success rates for patients with difficult intravenous access and a single operator, dynamic, short-axis ultrasound technique.

Nurse knowledge and confidence on peripheral intravenous catheter insertion and maintenance in pediatric patients: A multicentre cross-sectional study

PURPOSE

To examine nursing knowledge and confidence of peripheral intravenous catheter insertion and maintenance in pediatric patients.

DESIGN AND METHODS

An online survey using validated questionnaires was conducted in ten (tertiary and district) hospitals in Indonesia from May to September 2020. Multivariable general linear models were used to investigate associations between nurses' characteristics and knowledge and confidence on the catheter insertion and maintenance score.

RESULTS

A total of 413 out of 458 pediatric nurses completed the survey (a response rate of 90%). The mean score of the nurse knowledge on insertion was 18.9(±3.3) (maximum score: 21), and the maintenance score was 6.5(±2.0) (maximum score: 12). The median score of the nurse insertion and maintenance confidence was quite high: 44 (IQR = 7) out of 50 and 37 (IQR = 4) out of 45, respectively. Initial patient assessment, catheter securement, site assessment and management of complications are areas where nurse knowledge and confidence are still lacking. Adjusted analysis indicates that training and work experience were significantly associated with the knowledge and confidence score (p < 0.05).

CONCLUSION

Pediatric nurses were largely confident in their skills but this was not reflected in their knowledge scores. Training and experience were important predictors for nursing knowledge and confidence in catheter insertion and maintenance.

PRACTICE IMPLICATIONS

The results provide nursing and hospital managers and educational institutions to understand areas of intravenous catheter insertion and maintenance in which nurses lack of knowledge and confidence as well as to formulate tailored and ongoing training to improve nurse knowledge, confidence, practices and optimize patients' care.

Assessment of Reflux From Needleless Connectors: Blinded Comparison of Category Designation to Benchtop Function Using a Venous Simulator

Needleless connectors (NCs) for vascular access have limited needlestick injuries, but complications including occlusion, thrombosis, and infections have increased despite reduced needlestick injuries. These complications relate to the ability of an NC design to limit volume fluctuations that can lead to fluid reflux with potential for microbial contamination. Different NC designs requiring specific usage protocols and training, a lack of clarity in NC function relative to manufacturer-designated categories, and confounding results from a limited number of studies comparing different NCs have resulted in confusion, ultimately leading to complications from undesirable fluid movement within the vascular access. The authors therefore quantified the magnitude of reflux with current commercially available NCs using a venous stimulator. Thirteen blinded NC designs spanning the categories of negative and positive displacement, neutral, and antireflux were tested to quantify fluid movement upon disconnection and reconnection from a representative intravenous pressure (3 NCs per design; 10 trials per NC). Trials for each NC tested followed consistent displacement trends leading to tight error bars. Blinded NCs were then characterized according to their function and compared with their category designation after unblinding. All positive and negative NCs functioned in a manner consistent with their respective category designations. Conversely, all NCs categorized as neutral actually functioned with negative displacement (ie, reflux upon disconnection; 4/5 NCs) or positive displacement (1/5 NCs). Only NCs classified as antireflux functioned as neutral, which was confirmed in a blinded bidirectional flow test. These results suggest that the neutral NC-marketed category may be confusing to users unless the particular NC design has an integrated antireflux component.

UK Vessel Health and Preservation (VHP) Framework: a commentary on the updated VHP 2020

BACKGROUND

In 2016, a UK vessel health and preservation (VHP) framework was developed to support healthcare staff to select the most appropriate vascular access device for patients requiring intravenous therapy. The VHP framework was based on available evidence and expert consensus. The VHP was based on available evidence and expert consensus.

DEVELOPMENT OF THE VHP 2020 FRAMEWORK

A multidisciplinary team reviewed the original UK VHP framework and considered new published evidence, national and international guidelines and expert opinion. A literature search was performed using Cinahl and Medline, incorporating a variety of terms linked to vascular access devices, assessment and selection. Articles published in and after 2014 in English were included. Twelve articles were found to be relevant including three evidence-based guidelines, two randomised control trials and one systematic review.

FINDINGS

Three main studies provided the evidence for the update: the MAGIC study that assessed the appropriateness of peripherally inserted central catheters in patients; a study that utilised the 'A-DIVA scale' to predict the likelihood of difficult venous access; and a study that incorporated an 'I-DECIDED tool' for peripheral intravenous catheter assessment and decision-making for device removal. In addition, published guidelines provided evidence that the original advice on appropriate osmolarity of medicines for peripheral administration needed updating.

CONCLUSION

The 2020 UK VHP framework reflects latest evidence-based research and guidelines, providing healthcare staff updated guidance to assist in maintaining good practice in vascular access assessment and device selection and patient safety.

L, Mihala G, Harris PNA, Rickard CM. SECUREment bundles to prevent peripheral intravenous catheter failure—the SECURE-PIVC trial: study protocol for a pilot randomized controlled trial

Introduction

Peripheral intravenous catheters (PIVCs) are widely used, but failure is unacceptably common with up to 69% failing before treatment is complete. PIVC securement reduces failure, but the optimal way to achieve this is unclear. Tapes and supplementary securement products are widely used, however rigorous testing of these to reduce PIVC failure remains unexplored.

Methods and analysis

In adult medical-surgical wards at a tertiary hospital, this pilot randomized controlled trial tests standard care (bordered polyurethane dressing plus nonsterile tape over the extension tubing) against two securement interventions (intervention one: standard care plus two sterile tape strips over the PIVC hub; intervention two: intervention one plus a tubular bandage). Patients >18 years of age requiring a PIVC for >24 hours are eligible. Patients with laboratory-confirmed positive blood cultures within 24 hours of screening, known allergy to study products, current or high-risk of skin tear, or non-English speaking without interpreter are excluded. Sample size is 35 per trial arm, and central randomization is computer-generated with allocation concealed until entry. Patients and clinical staff cannot be blinded to treatment allocation. However, infection outcomes are assessed by a blinded investigator. Primary outcome is study feasibility. Secondary outcomes (PIVC failure, dwell time, skin adverse events, PIVC colonization, and cost) are compared between groups. Feasibility outcomes are reported descriptively.

Ethics and trial commencement

Ethical approvals were received from Royal Brisbane and Women's Hospital (HREC/18/QRBW/44571) and Griffith University (2018/1000). Trial commencement was May 2019. Trial registration: ACTRN12619000026123.

Translation and Validation of the Modified A-DIVA Scale to European Portuguese: Difficult Intravenous Access Scale for Adult Patients

(1) Background: In Portugal, no accurate and reliable predictive instruments are known that could assist healthcare professionals in recognizing patients with difficult venous access. Thus, this study aimed to translate and validate the Modified A-DIVA scale to European Portuguese. (2) Methods: A methodological and cross-sectional study was conducted in two phases: translation of the Modified A-DIVA scale to European Portuguese following six stages proposed by Beaton and collaborators, and assessment of its psychometric properties in a non-probability sample of 100 patients who required peripheral intravenous catheterization in a Portuguese hospital. (3) Results: The European version of the Modified A-DIVA scale (A-DM scale) showed excellent inter-rater accordance scores, k = 0.593 (95% CI, 0.847 to 0.970), p < 0.0005. The A-DM scale's criterion and construct validity was assessed through predictive, convergent, and correlational analysis with variables identified in the literature as associated with difficult peripheral intravenous access, with moderate to large magnitudes and statistical significance. (4) Conclusions: The A-DM scale is a reliable and valid instrument that can support healthcare professionals and researchers in the early identification of patients at risk of difficult peripheral intravenous access. Future validation studies are needed to test the A-DM scale's applicability across clinical settings and in different patient cohorts.

Characteristics of expert nurses' assessment of insertion sites for peripheral venous catheters in elderly adults with hard-to-find veins

AIM

To clarify the characteristics of expert nurses' assessments when selecting an insertion site for a peripheral venous catheter (PVC).

METHODS

Participants were 11 competent (control group) and 13 expert nurses. Using a simulated patient, we recorded the procedures participants followed when selecting a site for a PVC insertion. The researchers interviewed the nurses after the procedure by asking targeted questions about the site selection to clarify the factors influencing that selection. During the interview, a video of that nurse's procedure was observed, and each step performed during the procedure was investigated.

RESULTS

We identified three assessment characteristics specific to expert nurses that influenced their PVC site selection: (a) focusing on a patient's unique characteristics and choosing the appropriate procedure for that individual; (b) avoiding complications and paying attention to the patient's daily self-care needs; and (c) carefully considering the patient's fear and fatigue during site selection and catheter insertion. Other assessments, based on the general knowledge and skill acquired by nurses in selecting a PVC site, were common to both groups: arm selection based on the patient's preference and site selection to avoid nerve injuries or complications. The control group's approach was assessed on the basis of their confidence in selecting a site for a PVC insertion.

CONCLUSIONS

Expert nurses assessed the patient's individual characteristics and daily self-care needs and helped mitigate the patient's anxiety. Our findings provide a basis for educational programs that share how expert nurses assess sites for a PVC insertion.

A comparison of hydrophobic polyurethane and polyurethane peripherally inserted central catheter: results from a feasibility randomized controlled trial

Background

To evaluate the feasibility of an efficacy trial comparing a hydrophobic polyurethane peripherally inserted central catheter (PICC) with a standard polyurethane PICC.

Methods

This pilot randomised controlled trial (RCT) was conducted between May 2017 and February 2018. Adult participants (n = 111) were assigned to hydrophobic polyurethane PICC with proximal valve (intervention) or a polyurethane PICC with external clamp (standard care). Primary outcome was trial feasibility including PICC failure. Secondary outcomes were central line-associated bloodstream infection, local infection, occlusion, thrombosis, fracture and dislodgement, phlebitis, local or systemic allergic reaction, and PICC dwell time.

Results

All feasibility outcomes were achieved, apart from eligibility criteria. In total, 338 patients were screened, 138 were eligible (41%), and of these 111 were randomised (80%). Patients received the allocated PICC in 106 (95%) insertions. No patients withdrew from the study and there was no missing data. PICC failure was 24% (13/55) in the intervention group and 22% (12/55) in the standard care group (p = 0.820). PICC failure per 1000 PICC days was 16.3 in the intervention group and 18.4 in the control group (p = 0.755). The average dwell time was 12 days in the intervention and 8 days in the control group.

Conclusions

This study demonstrates the feasibility of an efficacy trial of PICC materials in an adult population, once adjustments were made to include not only in-patients, but also patients being discharged to the Hospital in the Home service.

Trial registration

Australia and New Zealand Clinical Trials Registry ACTRN12616001578493. Prospectively registered on 16 November 2016. The trial protocol was published a priori (Kleidon et al., Vasc Access 3:15–21, 2017).

Subcutaneous hydration and medications infusions (effectiveness, safety, acceptability): A systematic review of systematic reviews

OBJECTIVE

To synthesize the current evidence for subcutaneous hydration and medication infusions from systematic reviews and to assess their methodological quality.

INTRODUCTION

Peripheral intravascular cannula/catheter insertion is a common invasive procedure for administering fluids and medications. Venous depletion is a growing concern for several patient populations. Subcutaneous access for the administration of isotonic solutions and medications is an alternative; however, vascular access assessment and planning guidelines rarely consider this route.

METHODS

Systematic review of systematic reviews (PROSPERO CRD42018046504). We searched 6 databases published in English language from 1990 to June 2020, identifying subcutaneous infusions an alternate route for fluids or medication. Methodological quality was evaluated using AMSTAR 2 criteria and data for mechanisms of infusion and outcomes related to effectiveness, safety, efficiency and acceptability extracted. The Johanna Briggs Institute's grades of recommendation informed the strength of recommendation.

RESULTS

The search yielded 1042 potential systematic reviews; 922 were excluded through abstract and duplicate screen. Of the remaining articles, 94 were excluded, and 26 were included. Overall, evidence is strong for recommending subcutaneous hydration infusions for older adults, weak for pediatric patients and inconclusive for palliative patients. There is strong evidence for 10 medications; weak evidence supporting 28 medications; however, there are eight medications with inconclusive evidence to make a recommendation and four medications not appropriate for subcutaneous delivery.

CONCLUSION

Subcutaneous access should be considered alongside intravenous therapy for hydration in older adults, and several medications. There are additional benefits in terms of ease of use and cost-effectiveness of this mode. Inclusion of subcutaneous access in clinical guidelines may promote uptake of this route to help preserve vessel health of vulnerable patients. Further high-quality research is needed to inform subcutaneous infusion therapy in a variety of populations (including pediatrics and palliative care) and medications and clarifying the mechanism of delivery.

Reflections on setting up a nurse-led paediatric peripherally inserted central catheter service

The aim of this article is to present the experience of starting a paediatric peripherally inserted central catheter (PICC) service and setting up a nurse-led paediatric PICC insertion service. The periods in review are divided into two: the trial phase and the interim service phase. The trial phase took place between October 2014 and December 2016. During this period, a total of 55 lines were inserted. The interim service phase, which is ongoing, pending the ratification of the business case, has resulted in 301 inserted PICC lines. The interim period discussed covers January 2017 to December 2019.

Implementing an emergency department vascular access team: A quality review of training, competency, and outcomes

Peripheral intravenous catheters are frequently used devices in emergency departments. Many patients now present with difficult anatomy and are labeled as difficult intravenous access patients. A common technology to address this challenge is ultrasound. While studies have examined the ability to train emergency staff, few have addressed how this should be done and the outcomes associated with such training. No studies were found with dedicated vascular access specialist teams in emergency departments. An emergency department vascular access specialist team was formed at a hospital in Bangor, Maine, United States to train, validate, and proctor clinicians with ultrasound-guided peripheral intravenous devices. A quality review of this process was compiled and determined that appropriate clinicians with dedicated training and guidance can achieve higher levels of procedural success. Furthermore, evidence substantiates that frequent practice is linked to a higher quality of care and that a significant need for such teams is present. This review examines how a team was implemented and its impact both department- and facility-wide. It is possible that hospitals benefit from the services of vascular access specialists to provide higher quality care. Successful implementation of such specialist teams requires foundational knowledge and skills in vascular access with ongoing quality measures to ensure competency and compliance with evidence-based practices.

The Michigan Appropriateness Guide for Intravenous Catheters in Pediatrics: miniMAGIC

OBJECTIVES

Vascular access device decision-making for pediatric patients remains a complex, highly variable process. To date, evidence-based criteria to inform these choices do not exist. The objective of the Michigan Appropriateness Guide for Intravenous Catheters in pediatrics (miniMAGIC) was to provide guidance on device selection, device characteristics, and insertion technique for clinicians, balancing and contextualizing evidence with current practice through a multidisciplinary panel of experts.

METHODS

The RAND Corporation and University of California, Los Angeles Appropriateness Method was used to develop miniMAGIC, which included the following sequential phases: definition of scope and key terms, information synthesis and literature review, expert multidisciplinary panel selection and engagement, case scenario development, and appropriateness ratings by an expert panel via 2 rounds.

RESULTS

The appropriateness of the selection, characteristics, and insertion technique of intravenous catheters commonly used in pediatric health care across age populations (neonates, infants, children, and adolescents), settings, diagnoses, clinical indications, insertion locations, and vessel visualization devices and techniques was defined. Core concepts including vessel preservation, insertion and postinsertion harm minimization (eg, infection, thrombosis), undisrupted treatment provision, and inclusion of patient preferences were emphasized.

CONCLUSIONS

In this study, we provide evidence-based criteria for intravenous catheter selection (from umbilical catheters to totally implanted venous devices) in pediatric patients across a range of clinical indications. miniMAGIC also highlights core vascular access practices in need of collaborative research and innovation.

A prospective audit evaluating use of urokinase in oncology patients with occluded central venous access devices

This article reports the results of a single-site prospective audit evaluating the safety and effectiveness of urokinase (Syner-Kinase^®) to restore patency in central venous access devices (CVADs) for cancer patients. CVADs are routinely inserted to allow the safe and timely administration of systemic anti-cancer therapies; therefore, catheter dysfunction can interrupt the treatment schedule and adversely affect patient outcome. The aim was to contribute to the development of evidence-based, standardised, best practice guidelines. Prospective data were collected from all patients (n=22) identified with an occluded CVAD, requiring use of Syner-Kinase to manage a persistent withdrawal occlusion or total occlusion, over a 6-month period. Findings revealed a single administration of Syner-Kinase for catheter occlusion clearance to be effective in 92% of cases. Results suggest that use of the thrombolytic agent is well-tolerated and an effective means of restoring patency for long-term CVADs in cancer patients.

Vessel Health and Preservation: a model and clinical pathway for using vascular access devices

Use of intravenous devices for the delivery of medical treatment spans all healthcare facilities ranging from hospitals to clinics and home care. Clinical pathways are processes used by healthcare providers to integrate and illustrate the best evidence and approach to care for a specific area of practice. The Vessel Health and Preservation (VHP) model is a framework and pathway process, consisting of four quadrants, to guide initiation and management of treatment requiring intravenous access. The pathway is designed to promote preservation of the vasculature of patients from admission through discharge with a focus on acute care. This article describes the model and pathway process. Moving through the quadrants of assessment/selection, insertion, management and evaluation of outcomes the clinician receives vascular access education to establish an understanding of the key principles and is then better able to provide care to the patient. Research on the VHP model has found that patients, clinicians and healthcare facilities benefit from the evidence integrated within the VHP model for improved outcomes, greater success with insertion, time saved through improved efficiency, risk reduced through appropriate device discontinuation, and greater patient satisfaction.

Peripheral intravenous catheter dressing and securement practice is associated with site complications and suboptimal dressing integrity: A secondary analysis of 40,637 catheters

BACKGROUND

With over 2 billion peripheral intravenous catheters used globally each year, avoiding complications is crucial for patients and healthcare organisations. Effective catheter dressing and securement is a key nursing strategy to reduce catheter failure and resultant patient harm.

OBJECTIVES

To describe global catheter dressing and securement practices and policy; and identify factors associated with catheter insertion site complications, and suboptimal dressing and securement.

DESIGN

Secondary analysis of a global cross-sectional study of peripheral intravenous catheter characteristics, management and outcomes.

SETTING

Four hundred and seven rural, regional and metropolitan hospitals in 51 countries.

PARTICIPANTS

Paediatric and adult patients with 40,637 catheters.

METHODS

Patient-, catheter-, and institution-related factors which could be associated with catheter site complications and suboptimal dressings were extracted from the parent database. Global trends in catheter dressing and securement policy and practice were described. Potential predictors of catheter and dressing complications were explored using logistic regression.

RESULTS

Dressing and securement practices, and local hospital policy regarding dressing change frequency varied. One fifth of dressings (21%, n = 8519) were not clean, dry and intact. The prevalence of catheter insertion site complications was 16% (n = 6503), with signs of phlebitis commonly observed (11.5%, n = 4587). Compared to non-bordered polyurethane dressings, sterile gauze and tape dressings were associated with fewer insertion site complications (odds ratio 0.58, 95% confidence interval 0.50-0.68) and better dressing integrity (odds ratio 0.68; 95% confidence interval 0.59-0.77); whereas, compared with no securement, non-sterile tape at the insertion site was associated with more site complications (odds ratio 2.39, 95% confidence interval 2.22-2.57) and poorer dressing integrity (odds ratio 1.64, 95% confidence interval 1.51-1.75). Two 'bundled' dressing and securement combinations were associated with fewer site and dressing complications, when compared with the reference category. Local catheter care guidelines which advocate 4th hourly insertion site inspection and dressing replacement between 1-3 days were associated with better catheter dressing integrity.

CONCLUSION

Modifiable risk factors for peripheral intravenous catheter site and dressing complications were identified and are amendable to further interventional testing.

The case for using implanted ports

Uses of central venous access devices (CVADs) include the administration of vital fluids and medications. Implanted ports are a type of CVAD that is used when long-term vascular access is required. The device is discreet and associated with a low risk of catheter-related bloodstream infection. This article describes the different types and components of ports and how to select them. It explains how to insert ports, and provides guidance on accessing and de-accessing them

Risk factors for a difficult intravenous access: A multicentre study comparing nurses' beliefs to evidence

AIMS AND OBJECTIVES

To summarise the evidence about patient-related risk factors for difficult intravenous access in adults, and at identifying nurses' beliefs and their consistency with evidence.

BACKGROUND

Peripheral intravenous cannulation is a common procedure for nurses, but rates of failure at first attempt of peripheral intravenous cannulation range 10%-40%. Nurses' beliefs about difficult intravenous access factors might influence their clinical practice more than current evidence.

DESIGN

The study included a literature review of the evidence on patient-related risk factors for difficult intravenous access, the development of an instrument to investigate nurses' beliefs about this topic and a cross-sectional multicentre survey on clinical nurses.

METHODS

The quality of the studies included was evaluated through the Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies. A synthesis of evidence for each risk factor was produced. A survey instrument was developed including 26 risk factors, which were then rated by nurses as perceived predictors of difficult intravenous access. The STROBE guidelines for study reporting were followed.

RESULTS

Four hundred and fifty clinical nurses working in four hospitals in Italy were surveyed. Nurses' beliefs were in line with evidence in considering body mass index, drug abuse, lymphadenectomy and chemotherapy as difficult intravenous access factors. Beliefs about difficult intravenous access factors were influenced by nurses' work experience and frequency of peripheral intravenous cannulation. Nurses also identified as risk factors for difficult intravenous access oedema, thrombophlebitis, hypovolaemia, skin lesions and irritant therapies, which have been minimally investigated by research.

CONCLUSIONS

An overall congruence between nurses' beliefs and evidence about risk factors for difficult intravenous access was found. With their expertise, nurses may fill the knowledge gap of clinical evidence and open new paths for clinically meaningful research.

RELEVANCE TO CLINICAL PRACTICE

Nurses' beliefs about difficult intravenous access factors can be influenced by their work experience and clinical setting. Integrating nurses' beliefs with scientific evidence can increase the quality of care.

Reassessing standards of vascular access device care: a follow-up audit

This article reports on the findings of a repeat audit of vascular access devices (VADs) in a district general hospital undertaken 4 years after a previous audit. The first demonstrated poor standards of care and low compliance with evidence-based guidelines, indicating that a change in practice was necessary. A strategy of training, education and standardisation for intravenous devices was introduced, with the goal of transforming practice to raise standards and improve compliance. The findings of the follow-up audit show that the strategy has been successful in raising standards of care and reducing infections.

Clinical Impact of Chronic Venous Changes Induced by Central Lines in Children: A Cohort with Abnormal Venograms

PURPOSE

To explore the hypothesis that central venous stenosis/obstructions (CVS/O) in children are influenced by prior central venous access devices (CVADs) and are associated with future risk for thromboses.

MATERIAL AND METHODS

A convenience sample of 100 patients with abnormal venography (stenosis, collaterals, occlusions) documented during peripherally inserted central catheter (PICC) placements were identified from consecutive PICC placements (January 2008 to November 2012). The patients (41 males, 59 females, median age 2.7 years, median weight 11 kg) were categorized based on venographic presence (Group A, n = 53) or absence (Group B, n = 47) of visible connection to the superior vena cava. Each patient's CVAD history, before and after venography, was analyzed (until October 2016).

RESULTS

Before venogram, Group B patients were associated with a higher number of previous CVADs, larger diameter devices, greater incidence of malposition, and more use of polyurethane catheters than Group A patients (P < .001). An ipsilateral PICC was successfully placed in 98% of Group A, compared to 32% of Group B (P < .001). After venogram, significantly more Doppler ultrasounds (DUS) were performed and thromboses diagnosed in Group B (57% and 36%) compared to Group A (21% and 8%) (P < .003; P = .001), respectively.

CONCLUSIONS

Previous catheter characteristics influenced the severity of venographic changes of CVS/O (Group B). Group B was associated with more subsequent symptomatic thromboses. This information may assist parents and referring physicians to anticipate potential adverse sequelae from CVS/O on the child's venous health.

Derivation of a clinical decision-making aid to improve the insertion of clinically indicated peripheral intravenous catheters and promote vessel health preservation. An observational study

Background

It is well established that the idle peripheral intravenous catheter (PIVC) provides no therapeutic value and is a clinical, economic and above all, patient concern. This study aimed to develop a decision aid to assist with clinical decision making to promote clinically indicated peripheral intravenous catheter (CIPIVC) insertion in the emergency department (ED) setting. Providing evidence for a uniform process could assist clinicians in a decision-making process for PIVC insertion. This could enable patients receive appropriate vascular access healthcare.

Methods

We performed a secondary analysis of data from a multicentre cohort of emergency department clinicians who performed PIVC insertion. We defined CIPIVC a priori as one used for a specific clinical treatment and or procedure such as prescribed intravenous (IV) fluids; prescribed IV medication; or IV contrast (for computerized tomography scans). We sought to refute or validate an assumption if the clinician performing or requesting the insertion decided the patient was >80% likely to need a PIVC. Using logistic regression, we derived a decision aid for CIPIVCs.

Results

In 817 patients undergoing PIVC insertion, we observed 68% of these to be CIPIVCs. Admitted patients were significantly more likely to have a CIPIVC, Odds Ratio (OR) = 3.05, 95% confidence interval (CI) = 2.17–4.30, p = <0.0001. Before insertion, patients who definitely needed IV fluids/medicines OR = 3.30, 95% CI = 2.02–5.39, p = <0.0001 and who definitely needed a contrast scan OR = 3.04, 95% CI = 1.15–8.03, p = 0.0250 were significantly more likely to have a device inserted for a clinical indication. Patients who presented with an existing vascular access device were more likely to have a new CIPIVC inserted for use OR = 4.35, 95% CI = 1.58–11.95, p = 0.0043. The clinician’s pre-procedural judgment of the likelihood of therapeutic use >80% was independently associated with CIPIVC; OR 3.16, 95% CI = 2.06–4.87, p<0.0001. The area under the receiver operating characteristic curve was 0.81, and at the best cut-off, the model had a specificity of 0.81, sensitivity of 0.71, a positive predictive value of 0.89 and negative predictive value of 0.57.

Conclusions

Using the derived decision aid, clinicians could ask:- “Does this patient need A-PIVC?” Clinicians can decide to insert a CIPIVCs when: (i) Admission to hospital is anticipated and when (ii) a Procedure requires a PIVC, e.g., computerised tomography scans and where an existing suitable vascular access device is not present and or; (iii) there is an indication for IV fluids and or medicines that cannot be tolerated enterally and are suitable for dilution in peripheral veins; and, (iv) the Clinician’s perceived likelihood of use is greater than 80%.

Accepted but Unacceptable: Peripheral IV Catheter Failure

Peripheral intravenous (IV) catheter insertion, the most common invasive hospital procedure performed worldwide, is associated with a variety of complications and an unacceptably high overall failure rate of 35% to 50% in even the best of hands. Catheter failure is costly to patients, caregivers, and the health care system. Although advances have been made, analysis of the mechanisms underlying the persistent high rate of peripheral IV failure reveals opportunities for improvement.

Vessel health and preservation: An integrative review

AIMS AND OBJECTIVES

To describe and synthesise current knowledge on the maintenance and preservation of vessels in patients who need the placement of a vascular access device.

INTRODUCTION

To administer drugs, blood or intravenous fluids, nurses or doctors insert a peripheral vascular access device on the arm using the traditional approach. This approach implies that devices are blindly inserted until flow is satisfactory and all possible sites have been exhausted. A proactive approach would ensure at the outset that the best device is used for each patient, eliminating repeated attempts at cannulation.

DESIGN

An integrative review was conducted using data recorded until July 2017. Searches were conducted in PubMed, Cochrane Library, CINAHL and Scopus.

REVIEW METHOD

A modified version of Cooper's five-stage method and the PRISMA guidelines were used to perform the integrative review.

RESULTS

Nine papers were included in this review. The patients were active participants in a proactive approach to vessel health and preservation. The involvement of each healthcare professional in vessel health and preservation improves outcomes and expands the use of a proactive approach to vascular device management. Because nurses are directly involved in the use of such devices and support patients during the decision-making process, they should take the lead in the use of the proactive approach.

CONCLUSION

Despite the many documented advantages of the proactive approach to preserving vessels in many settings and healthcare systems, it has not been widely tested. Future research is needed to guarantee high-quality vessel health and preservation care, thus contributing to the development and dissemination of the proactive approach.

RELEVANCE TO CLINICAL PRACTICE

The proactive approach preserves vessels for future needs, improves the delivery of the treatment plan and reduces length of stay, costs, risk of infection, complications and pain perceived by patients. This approach also ensures better use of nurses' time and vascular access device material.

Evaluation of Skin Colonisation And Placement of vascular access device Exit sites (ESCAPE Study)

Background

Skin microorganisms may contribute to the development of vascular access device (VAD) infections. Baseline skin microorganism type and quantity vary between body sites, yet there is little evidence to inform choice of VAD site selection.

Objective

To compare microorganisms present at different body sites used for VAD insertions and understand the effect of transparent dressings on skin microflora.

Methods

The ESCAPE observational study consisted of three phases: (1) skin swabs of four sites (mid-neck, base neck, chest, upper arm) from 48 hospital patients; (2) skin swabs of five body sites (mid-neck, base neck, chest, upper arm, lower arm) from 10 healthy volunteers; and (3) paired skin swabs (n = 72) under and outside of transparent dressings from 36 hospital patients (16 mid/base neck, 10 chest, upper arm). Specimens were cultured for 72 h, species identified and colony-forming units (CFU) counted. Ordinal logistic regression compared CFU categories between variables of interest.

Results

The chest and upper arm were significantly associated with fewer microorganisms compared to neck or forearm (odds ratio [OR] = 0.40, 95% confidence interval [CI] = 0.25-0.65, P < 0.05). CFU levels under transparent dressings were not significantly different from outside (OR = 0.57, 95% CI = 0.22-1.45). Staphylococci were predominant at all sites. Other significant (P < 0.05) predictors of higher CFU count included prolonged hospitalisation and medical/surgical patient status.

Discussion

Skin microorganism load was significantly lower at the upper arm or chest, compared to the mid- or base neck. This may impact VAD site selection and subsequent infection risk.

Implementing the I-DECIDED clinical decision-making tool for peripheral intravenous catheter assessment and safe removal: protocol for an interrupted time-series study

INTRODUCTION

Millions of acute care hospital patients need a peripheral intravenous catheter (PIVC) each year. However, up to half of PIVCs remain in situ when not being used, and 30%-50% of intravenous (IV) catheters develop complications or stop working before treatment is finished, requiring the insertion of a new device. Improved assessment could prompt timely removal of redundant catheters and prevent IV complications. This study aims to validate an evidence-based PIVC assessment and decision-making tool called I-DECIDED and evaluate the effect of implementing this tool into acute hospital clinical practice.

METHODS AND ANALYSIS

The protocol outlines a prospective, multicentre, mixed-methods study using an interrupted time-series (multiple measures preintervention and postintervention) implementation at three Australian hospitals between August 2017 and July 2018. The study will examine the effectiveness of the I-DECIDED assessment and decision-making tool in clinical practice on prompting timely PIVC removal and early detection of complications. Primary outcomes are prevalence of redundant PIVCs (defined as device in situ without a clear purpose), IV complications (occlusion, dislodgement, infiltration, extravasation and phlebitis) and substandard dressings (loose, lifting, moist or soiled); device utilisation ratios; and primary bloodstream infection rates. Secondary outcomes including staff barriers and enablers to PIVC assessment and removal, patient participation, documentation of PIVC assessment and decisions taken to continue or remove the PIVC will be recorded. Using the Promoting Action on Research Implementation in Health Services framework, we will undertake staff focus groups, bedside patient interviews and PIVC assessments and chart audits. Patients aged 18 years or more with a PIVC will be eligible for inclusion.

ETHICS AND DISSEMINATION

Ethical approval from Queensland Health (HREC/17/QPCH/47), Griffith University (Ref No. 2017/152) and St Vincent's Health and Aged Care Human Research and Ethics Committee (Ref No. 17/28). Results will be published.

The Risk of Adverse Events Related to Extended-Dwell Peripheral Intravenous Access

Midline catheters (MCs) may be useful to avoid repeated venipuncture in patients requiring prolonged intravenous infusions with limited adverse events (AEs). We analyzed 2 Italian hospital databases to ascertain the safety of MCs. Among 1,538 adult patients, 154 MC-related AEs (10%; 2.49 AEs per 1,000 MC days) were reported.Infect Control Hosp Epidemiol 2018;875-877.

Vascular access specialist teams for device insertion and prevention of failure

BACKGROUND

Most people admitted to hospitals worldwide require a vascular access device (VAD). Hundreds of millions of VADs are inserted annually in the USA with reports of over a billion peripheral intravenous catheters used annually worldwide. Numerous reports suggest that a team approach for the assessment, insertion, and maintenance of VADs improves clinical outcomes, the patient experience, and healthcare processes.

OBJECTIVES

To compare the use of the vascular access specialist team (VAST) for VAD insertion and care to a generalist model approach for hospital or community participants requiring a VAD in terms of insertion success, device failure, and cost-effectiveness.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 1); Ovid MEDLINE (1950 to 7 February 2018); Ovid Embase (1980 to 7 February 2018); EBSCO CINAHL (1982 to 7 February 2018); Web of Science Conference Proceedings Citation Index - Science and Social Science and Humanities (1990 to 7 February 2018); and Google Scholar. We searched the following trial registries: Australian and New Zealand Clinical Trials Register (www.anzctr.org.au); ClinicalTrials.gov (www.clinicaltrials.gov); Current Controlled Trials (www.controlled-trials.com/mrct); HKU Clinical Trials Registry (www.hkclinicaltrials.com); Clinical Trials Registry - India (ctri.nic.in/Clinicaltrials/login.php); UK Clinical Trials Gateway (www.controlled-trials.com/ukctr/); and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP) (www.who.int/trialsearch). We searched all databases on 7 February 2018.

SELECTION CRITERIA

We planned to include randomized controlled trials (RCTs) that evaluated the effectiveness of VAST or specialist inserters for their impact on clinical outcomes.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures recommended by Cochrane and used Covidence software to assist with file management.

MAIN RESULTS

We retrieved 2398 citations: 30 studies were eligible for further examination of their full text, and we found one registered clinical trial in progress. No studies could be included in the analysis or review. We assigned one study as awaiting classification, as it has not been accepted for publication.

AUTHORS' CONCLUSIONS

This systematic review failed to locate relevant published RCTs to support or refute the assertion that vascular access specialist teams are superior to the generalist model. A vascular access specialist team has advanced knowledge with regard to insertion techniques, clinical care, and management of vascular access devices, whereas a generalist model comprises nurses, doctors, or other designated healthcare professionals in the healthcare facility who may have less advanced insertion techniques and who care for vascular access devices amongst other competing clinical tasks. However, this conclusion may change once the one study awaiting classification and one ongoing study are published. There is a need for good-quality RCTs to evaluate the efficacy of a vascular access specialist team approach for vascular access device insertion and care for the prevention of failure.

Not "just" an intravenous line: Consumer perspectives on peripheral intravenous cannulation (PIVC). An international cross-sectional survey of 25 countries

Peripheral intravascular cannula/catheter (PIVC) insertion is a common invasive procedure, but PIVC failure before the end of therapy is unacceptably high. As PIVC failure disrupts treatment and reinsertion can be distressing for the patient, prevention of PIVC failure is an important patient outcome. Consumer participation in PIVC care to prevent failure is an untapped resource. This study aimed to understand consumers’ PIVC experience; establish aspects of PIVC insertion and care relevant to them; and to compare experiences of adult consumers to adult carers of a child. An international, web-based, cross-sectional survey was distributed via social media inviting adult consumers and adult carers of a child under 18 years who had experienced having a PIVC in the last five years (one survey each for adults and adult carers) to complete a 10-item survey. As such, sampling bias is a limitation and results should be carefully considered in light of this. There were 712 respondents from 25 countries, mainly female (87.1%) and adults (80%). A little over 50% of adults described insertion as moderately painful or worse, with level of insertion difficulty (0–10 scale) identified as moderate (median 4, IQR 1, 7). Adult carers reported significantly more pain during insertion and insertion difficulty (both p < 0.001). Rates of first insertion attempt failure were higher in children compared with adults (89/139 [64%] vs 221/554 [40%]; p < 0.001), and 23% of children required ≥ 4 attempts, compared with 9% of adults (p < 0.0001). Three themes from open-ended question emerged: Significance of safe and consistent PIVC care; Importance of staff training and competence; and Value of communication. The PIVC experience can be painful, stressful and frustrating for consumers. Priorities for clinicians and policy makers should include use of pain relief as standard practice to reduce the pain associated with PIVC insertion and developing strategies to increase first PIVC insertion attempt success particularly for children and older consumers.

Vessel Health and Preservation Framework: Use of the outcome logic model for evaluation

Background

Vascular access is an important part of many patient care management plans, but has unwanted risks. A working group led by the Infection Prevention Society (IPS) produced a Vessel Health and Preservation (VHP) Framework. Based on current evidence, a framework was developed for frontline staff to assess and select the best vascular access device to meet the individual patient's needs and to preserve veins for future use.

Methods

Using the Outcome Logic Model, we conducted an evaluation of the short- and medium-term outcomes with regards to the impact and success of the VHP Framework.

Results

This evaluation found that many respondents were aware of the framework and were using it in a range of different ways. Participants saw the framework as being most beneficial to help decisions on device choice and peripheral vein assessment. However, the framework has not fully reached its intended audience.

Discussion

Many positive outcomes were reported as a result of using the VHP Framework including improving clinical practice as it relates to the VHP elements. However, further work is required to find the tools to extend the reach of the framework and assist healthcare teams to be able to fully implement it within their clinical settings.

A clinical pathway for the management of difficult venous access

BACKGROUND

Many patients are admitted to hospital with non-visible or palpable veins, often resulting in multiple painful attempts at cannulation, anxiety and catheter failure. We developed a difficult intravenous pathway at our institution to reduce the burden of difficult access for patients by increasing first attempt success with ultrasound guidance. The emphasis was to provide a solution for hospitalised patients after business hours by training the after-hours clinical support team in ultrasound guided cannulation.

METHODS

Inception cohort study of patients referred to the after-hours clinical support team including outcomes such as number of attempts at cannulation before and after referral, insertion site, type of device inserted and recorded pain score for attempts prior to referral and for attempts by the after-hours clinical support team.

RESULTS

Between January and December 2016, 379 patients were referred to the after-hours clinical support team for placement of a peripheral intravenous catheter under ultrasound guidance. The median number of unsuccessful attempts before referral was 2 (IQR 2, 4), this ranged between 1 attempt to 10 attempts compared to only 1 attempt (IQR 1, 1, p < 0.001) with no more than 2 attempts in total by the after-hours clinical support team. The first time success rate by the after-hours clinical support team was 93% (n = 348). The median pain score for attempts with ultrasound use was 2/10 (IQR 1-3) compared to 7/10 (IQR 5-9) for previous attempts without ultrasound (p < 0.001).

CONCLUSION

The use of ultrasound guidance for peripheral intravenous catheter insertion by the after-hours clinical support team for patients with difficult venous access has been successful at our institution with 9 out of every 10 catheters inserted at first attempt with significantly lower recorded pain scores.

Tools, Clinical Prediction Rules, and Algorithms for the Insertion of Peripheral Intravenous Catheters in Adult Hospitalized Patients: A Systematic Scoping Review of Literature

BACKGROUND

First-time peripheral intravenous catheter (PIVC) insertion success is dependent on patient, clinician, and product factors. Failed PIVC insertion are an under-recognized clinical phenomenon.

OBJECTIVE

To provide a scoping review of decision aids for PIVC insertion including tools, clinical prediction rules, and algorithms (TRAs) and their findings on factors associated with insertion success.

METHODS

In June 2016, a systematic literature search was performed using the medical subject heading of peripheral catheterization and tool* or rule* or algorithm*. Data extraction included clinician, patient, and/or product variables associated with PIVC insertion success. Information about TRA reliability, validity, responsiveness, and utility was also extracted.

RESULTS

We screened 36 studies, and included 13 for review. Seven papers reported insertion success ranging from 61%-90% (4030 insertion attempts), 6 on validity, and 5 on reliability, with none reporting on responsiveness and utility. Failed insertions were associated with obesity (odds ratio [OR], 0.71-1.7; 2 studies) and smaller gauge PIVCs (OR, 6.4; 95% Confidence Interval [CI}, 3.4-11.9). Successful inser tions were associated with visible veins (OR, 0.87-3.63; 3 studies) or palpable veins (OR, 0.79-5.05; 3 studies) and inserters with greater procedural volume (OR, 4.4; 95% CI, 1.6-12.1) or who predicted that insertion would be successful (OR, 1.06; 95% CI, 1.04-1.07). Definitions of insertion difficulty are heterogeneous such as time to insert to a number of failed attempts.

CONCLUSIONS

Few well-validated reliable TRAs exist for PIVC insertion. Patients would benefit from a validated, clinically pragmatic TRA that matches insertion difficulty with clinician competency.

A Pilot Randomized Controlled Trial of Novel Dressing and Securement Techniques in 101 Pediatric Patients

PURPOSE

To evaluate feasibility of an efficacy trial comparing peripherally inserted central catheter (PICC) dressing and securement techniques to prevent complications and failure.

MATERIALS AND METHODS

This pilot, 3-armed, randomized controlled trial was undertaken at Royal Children's Hospital and Lady Cilento Children's Hospital, Brisbane, Australia, between April 2014 and September 2015. Pediatric participants (N = 101; age range, 0-18 y) were assigned to standard care (bordered polyurethane [BPU] dressing, sutureless securement device), tissue adhesive (TA) (plus BPU dressing), or integrated securement dressings (ISDs). Average PICC dwell time was 8.1 days (range, 0.2-27.7 d). Primary outcome was trial feasibility including PICC failure. Secondary outcomes were PICC complications, dressing performance, and parent and staff satisfaction.

RESULTS

Protocol feasibility was established. PICC failure was 6% (2/32) with standard care, 6% (2/31) with ISD, and 3% (1/32) with TA. PICC complications were 16% across all groups. TA provided immediate postoperative hemostasis, prolonging the first dressing change until 5.5 days compared with 3.5 days and 2.5 days with standard care and ISD respectively. Bleeding was the most common reason for first dressing change: standard care (n = 18; 75%), ISD (n = 11; 69%), TA (n = 4; 27%). Parental satisfaction (median 9.7/10; P = .006) and staff feedback (9.2/10; P = .002) were most positive for ISD.

CONCLUSIONS

This research suggests safety and acceptability of different securement dressings compared with standard care; securement dressings may also reduce dressing changes after insertion. Further research is required to confirm clinically cost-effective methods to prevent PICC failure.

The implementation of the Vessel Health and Preservation framework

Vascular access is an important component of health care but is not without associated risks, some of which can be life-threatening. The Vessel Health and Preservation (VHP) framework was developed with the intention of providing frontline staff with a resource to assist in assessing and selecting the best vascular access device to meet individual patient needs and to preserve veins for future use. This article examines the impact of the introduction of the framework into a haematology ward in an acute hospital in the North West of England during a 3-month pilot study. The results indicate that the VHP framework gave nursing staff more autonomy to choose the appropriate vascular access device for their patients and improved staff knowledge around pH and osmolality of intravenous drugs. However it is clear that more in-depth evaluations need to be conducted to assess the impact of VHP on patient care and outcomes.

Substantial harm associated with failure of chronic paediatric central venous access devices

Central venous access devices (CVADs) form an important component of modern paediatric healthcare, especially for children with chronic health conditions such as cancer or gastrointestinal disorders. However device failure and complications rates are high.Over 2½ years, a child requiring parenteral nutrition and associated vascular access dependency due to 'short gut syndrome' (intestinal failure secondary to gastroschisis and resultant significant bowel resection) had ten CVADs inserted, with ninesubsequently failing. This resulted in multiple anaesthetics, invasive procedures, injuries, vascular depletion, interrupted nutrition, delayed treatment and substantial healthcare costs. A conservative estimate of the institutional costs for each insertion, or rewiring, of her tunnelled CVAD was $A10 253 (2016 Australian dollars).These complications and device failures had significant negative impact on the child and her family. Considering the commonality of conditions requiring prolonged vascular access, these failures also have a significant impact on international health service costs.

Impact of arm selection on the incidence of PICC complications: results of a randomized controlled trial

INTRODUCTION

The aim of this study is to determine if right arm peripherally inserted central catheters (PICCs) experienced fewer complications while controlling for gender, hand dominance, history of malignancy, dwell time and catheter size.

METHODS

This was an intention-to-treat randomized controlled trial conducted in an academic medical center on two different sites between September 2012 and September 2015. All patients older than 18 years or age without known history of previous central line, contraindication to the use of a specific arm or hospitalized in the intensive care unit regardless of coagulation status, were considered for the study. Participants were randomized to the left or right arm group and were followed until catheter removal. Data collected included: PICC characteristics, insertion details, gender, arm dominance, history of malignancy, reason for insertion/removal, incidence of a complication and total dwell time. One-tailed hypothesis testing using a univariate logistic regression with odds ratio (OR) calculation was used to analyze the results. There were 202 patients randomly assigned, totaling 7657 catheter-days; 103 patients to the right-side group and 99 patients to the left-side group.

RESULTS

Participants in both groups were statistically equivalent for right handedness, gender, oncologic status, average dwell time and total catheter days. The overall incidence of complications on the right side was 23% versus 34% on the left side, confirming the hypothesis that right-sided insertions led to fewer complications (p = 0.046). The risk of a complication was reduced by 40% with right-sided insertion (OR 0.58 (CI: 0.31-1.09).

CONCLUSIONS

This study indicated fewer complications with right-sided insertion irrespective of hand dominance.
