The prevalence of peripheral intravenous cannulae and pattern of use: A point prevalence in a private hospital setting

Characteristics of Peripheral Intravenous Catheter Cannulation in Older Japanese Inpatients

Age-related physiological changes affect various aspects of peripheral intravenous catheter (PIVC) cannulation. However, the characteristics of PIVCs, especially in older patients, have been poorly investigated. In the current cross-sectional observational study, PIVC sizes, PIVC sites, the number of attempts until successful insertion, and the degree of venodilation upon insertion among hospital inpatients aged ≥65 years were investigated, along with measurements of the vessel diameter and depth using ultrasound. In total, 91 PIVC insertions were analyzed. The vessel diameter was estimated to be smaller than that in domestic adult inpatients. Most of the catheters were placed at the ideal site on the first attempt. However, considering the optimal vein-to-catheter ratio, most of the cannulations were oversized and would be oversized even when using a 24-gauge catheter. In addition, obvious differences were found in the vessel diameter, catheter size, and catheter site compared with previous studies conducted outside of Asia. The current study indicates the need for further research on the identification of appropriate veins, and the definition of "appropriate" approaches might vary among countries.

Predictors of ultrasound-guided peripheral intravenous catheter failure: A secondary analysis of existing trial data

OBJECTIVES

Ultrasound-guided (US) peripheral intravenous catheters (PIVC) have a high failure rate with many failing prior to completion of therapy. Risk factors associated with catheter failure are poorly delineated. This study aimed to assess risk factors related to catheter failure including patient, procedure, catheter, and vein characteristics to further elucidate which variables may impact catheter longevity.

METHODS

This was a secondary analysis using an existing trial dataset that primarily compared survival of two catheters: a standard long (SL) and an ultra-long (UL) US PIVC. Adult emergency room patients with difficult intravenous access at a tertiary care suburban academic center were study participants. Kaplan-Meier was employed to estimate the median catheter survival time. Cox regression univariable and multivariable analyses were used to evaluate the primary outcome of catheter survival.

RESULTS

Among 257 subjects, 63% of PIVCs survived until completion of therapy. In a multivariable Cox regression model, length of catheter in vein >2.75 cm (adjusted hazard ratio [aHR] 0.58, 95% confidence interval [CI] 0.37-0.90, p = 0.01) was associated with improved survival. First stick success decreased the risk of catheter failure (aHR 0.68, 95% CI 0.44-1.06, p = 0.09) but was not statistically significant. Factors associated with the increased risk of catheter failure included: depth of vein >1.2 cm (aHR 1.68, 95% CI 1.06-2.66, p = 0.03) and PIVC placement in right extremity (aHR 1.64, 95% CI 1.07-2.51, p = 0.02).

CONCLUSIONS

This study demonstrated that catheter length in vein (>2.75 cm) was associated with improved US PIVC survival highlighting the value of longer catheters in US PIVC survival. Choosing targets in the non-dominant extremity with shallower depths (⩽1.2 cm) may also increase catheter survival.

Spiced RCT: Success and Pain Associated with Intravenous Cannulation in the Emergency Department Randomized Controlled Trial

BACKGROUND

Peripheral venous cannulation is one of the most common procedures in medicine. A larger cannula allows higher rates of fluid to be provided if needed in a deteriorating patient; however, it is also perceived that larger-gauge cannula placement is associated with increased pain and procedural difficulty.

OBJECTIVE

This study aimed to compare the pain and procedural difficulty experienced during insertion between 18-gauge (18G) and 20-gauge (20G) cannulas.

METHODS

We conducted a single-blinded, randomized controlled trial on adult patients who required peripheral IV cannulation within a tertiary hospital emergency department between April and October 2018. Patients were randomized to either the 18G or 20G cannula group. The primary outcomes of the study-pain experienced by patients and procedural difficulties experienced by clinical staff-were recorded on two separate 10-cm visual analog scales. Other outcomes include first-attempt success rate, operator designation, complications, and the intent and actual use of the IV cannula were documented on preformatted questionnaires.

RESULTS

Data from 178 patients were included in the analysis. Eighty-nine patients were allocated to each cannula group. There were no statistically or clinically significant differences between mean pain score (0.23; 95% CI 0.56-1.02; p = 0.5662) and mean procedural difficulty score (0.12; 95% CI 0.66-0.93; p = 0.7396). between the two groups. There was no difference in first-attempt success rate (73 of 89 vs. 75 of 89; p = 0.1288), complications (2 of 89 vs. 1 of 89) between the 20G group and 18G group, respectively.

CONCLUSIONS

There was no significant difference between the 18G or 20G cannula for either pain experienced by patients or procedural difficulty experienced by clinicians.

Influence of simulation and clinical settings on peripheral vein cannulation skill learning in nursing education: A qualitative study

Background

Peripheral vein cannulation is a complex yet common practical skill. Learning to insert a peripheral vein cannula is fundamental in nursing education; however, the most beneficial pedagogical approaches are yet to be elucidated.

Objective

To explore and impart a deeper understanding of the learning conditions in nursing education for developing competency in peripheral vein cannulation.

Design

Qualitative, explorative. and comparative research design.

Settings

Two nursing educational settings in southern Norway: an academic setting for simulation-based peripheral vein cannulation skill learning, followed by a hospital setting that provided a 9 week clinical placement period.

Participants

Nine student nurses in the second year of a bachelor's programme in nursing.

Methods

Focus group interviews, individual interviews, and ad hoc conversations with the student nurses on their experiences during and after the process of developing competency in peripheral vein cannulation. Thematic analysis was used to identify categories and common themes.

Results

Eight major themes were identified: 'Anatomical and physiological conditions related to the training modalities', 'Realism in training', 'Sequences in peripheral vein cannulation training', 'Different training modalities affording varied learning opportunities', 'Professional nursing assessments', 'Patients' and peers' emotional reactions', 'Student nurses' own emotional reactions', and 'Significance of the relationship between the student nurse and patient'.

Conclusions

Simulation-based peripheral vein cannulation practice was an important starting point for the students' skill learning. However, the students experienced the complexity of the skill only in the clinical setting because it offered several learning opportunities. Nonetheless, our findings indicate a need to further review peripheral vein cannulation skill learning, especially patient contributing factors, to enhance the transfer of learning from the simulation setting to the clinical setting.

Tweetable abstract

Clinical setting-based peripheral vein cannulation practice is vital for student nurses' skill learning because of the skill's complexity.

CE: Evidence-Based Practice for Peripheral Intravenous Catheter Management

ABSTRACT

Peripheral intravenous catheters (PIVCs) are among the most common invasive devices used in hospitalized patients, with over 300 million sold in the United States each year. However, about one-fourth of PIVCs are left in situ with no prescriber orders for IV medications or solutions, "just in case" they might be needed. PIVC insertion can be painful, is often unnecessary, and may increase a patient's risk of developing a bloodstream infection. This article reviews the evidence for the appropriate use of short PIVCs in hospitalized patients, assesses the ongoing need for PIVCs, provides recommendations for alternative options, and argues for promptly removing a PIVC that is no longer in use.

Prevalence of peripheral intravenous catheters and policy adherence: A point prevalence in a tertiary care university hospital

AIMS AND OBJECTIVES

To determine prevalence and policy adherence for peripheral intravenous catheters (PIVC) in adult inpatients at a tertiary care university hospital (with about 83,000 inpatient admissions annually).

BACKGROUND

Up to 80% of hospitalised patients receive intravenous therapy, most commonly via PIVCs. However, these devices are not risk-free. Studies indicate that PIVC management standards in clinical practice are inadequate despite established policies promoting best practice. This leads to premature failure resulting in treatment delays, extended length of stay and potential compromised venous access for subsequent IV therapy.

DESIGN

Observational point prevalence study.

METHODS

Study undertaken on all adult acute care medical, surgical and oncology wards. Data were collected by senior registered nurses working in pairs on a single day. Descriptive statistics used to analyse data. SQUIRE 2.0 checklist for quality improvement reporting used.

RESULTS

There were 449 adult inpatients in 19 wards on survey day. One hundred and ninety-seven had one or more PIVCs in situ. The total number of PIVCs in-situ was 212. PIVC Prevalence was 47%. PIVCs were inserted in points of flexion such as antecubital fossa, back of hand or wrist in 52% of patients. Only 19% of cases had documented assessment of 8-hourly visual infusion phlebitis (VIP) score. Patients had local signs of phlebitis in 14.4% of cases. Patients were not aware of the reason/need for their PIVC in 44% of cases.

CONCLUSIONS

Discrepancies between evidence-based guidelines and local policy in clinical practice were identified including high rates of PIVC insertion in points of flexion and poor documentation. These quality problems increase likelihood of adverse patient outcomes especially when associated with limited patient awareness of the reason for their PIVC.

RELEVANCE TO CLINICAL PRACTICE

Poor adherence to best practice standards is 'accepted but unacceptable'. PIVC failure is costly to both patients and health systems. A strong focus on improvement in PIVC care and management is needed.

Dynamic Needle Tip Positioning versus Palpation and Ultrasound for Arteriovenous Puncture: A Meta-analysis

At present, dynamic needle-tip positioning (DNTP) technology is applied in arteriovenous puncture, challenging the use of ultrasound technology alone and palpation. Our goals were to extract data from experimental DNTP, ultrasound and palpation studies, using Review Manager, Version 5.3, for data analysis, and to evaluate whether DNTP has certain advantages in puncture. PubMed, EMBASE, the Cochrane Library, CNKI and WanFang Data Knowledge Service Platform were searched for randomized and non-randomized studies that compared DNTP with conventional ultrasound-guided techniques, no DNTP or palpation. The risk ratio with 95% confidence interval was calculated using the model corresponding to the I² value. Studies were identified to compare clinical indexes. With respect to clinical indexes, DNTP is better in terms of first-attempt success, overall success and complications. However, in infants, first-attempt success, overall success and number of additional punctures did not indicate good efficacy for DNTP compared with palpation. Artery puncture was also not performed well under ultrasound. On the basis of the current evidence, the advantages of DNTP over palpation and ultrasound are reflected in the successful first attempt rate of all groups and in all subgroups except infants. Therefore, for emergencies in elderly patients, DNTP can be used as a general method. Given that some of the studies were of low quality, more trials of high quality should be conducted to further verify the findings.

The impact of blood sampling technique, including the use of peripheral intravenous cannula, on haemolysis rates: A cohort study

AIMS

To explore the relationship between blood sampling techniques and haemolysis.

BACKGROUND

Haemolysis rates of blood samples have been thought to be influenced by the method of collection. There is a lack of research evidence available to clearly show the comparative risk of haemolysis across different blood sampling methods, including venepuncture and use of peripheral intravenous cannulas.

DESIGN

A prospective cohort study. Reporting followed the STROBE checklist.

METHODS

A trained observer was used to record blood sampling techniques over a 10-week period between April and June 2019. These records were then linked to pathology haemolysis results. Multivariable logistic regression was used to model patient and blood draw characteristics affecting haemolysis.

RESULTS

Most of the blood samples were not haemolysed (n = 324, 87.1%). Multivariable analysis showed haemolysis was associated with increased tourniquet duration and if the level of tube was less than half full. Univariable analysis showed haemolysis was associated with increased age of the patient, the difficulty of cannulation/ venepuncture and increased number of attempts. No difference was found in the haemolysis rate related to the qualification of the blood collector.

CONCLUSION

There was no significant difference in haemolysis rates associated with sampling blood from a PIVC compared with venepuncture. Research should be undertaken to determine whether education on the factors influencing haemolysis is useful in decreasing haemolysis rates.

RELEVANCE TO CLINICAL PRACTICE

There was no association with increased haemolysis rates when drawing blood via venepuncture compared with a peripheral intravenous cannula. Haemolysis of blood samples was associated with increased tourniquet duration, if level of the tube was less than half-filled, increased age of the patient and difficulty of blood draw. Awareness of the risk of haemolysis associated with specific blood sampling methods may assist clinicians to improve care.

Undergraduate nursing students' perceptions of the current content and pedagogical approaches used in PIVC education. A qualitative, descriptive study

BACKGROUND

The peripheral intravenous catheter (PIVC) is the most frequently used invasive medical device. PIVCs fail for a variety of reasons and failure often results in serious adverse events leading to patient discomfort, delays in treatment, increased health care costs and even death. Undergraduate nurses assess and manage PIVCs as part of their clinical learning. To date, no study has explored undergraduate nurses' perceptions of the education they receive about PIVCs.

AIM

We sought to critically explore the current state of education regarding PIVCs from the perspectives of undergraduate nurses.

METHODS

This qualitative study involved semi-structured interviews with third-year undergraduate nurses. Data were collected across two sites in Queensland, Australia. Fourteen face-to-face interviews were conducted and a modified 5-step qualitative content analysis was used to analyze the data.

FINDINGS

We identified three key domains relating to participants' experiences of PIVC education: 1) Universities provide foundational knowledge about PIVC assessment, management and removal; 2) Clinical practice consolidates and drives undergraduate nurses' knowledge, skills and confidence about PIVCs; and 3) inconsistencies in clinical practice and between individual clinicians impedes learning and knowledge translation about PIVCs.

CONCLUSION

Nursing students benefit from theoretical content delivered in the university setting. Practical application of theory and skill development whilst on clinical placement is variable. The current undergraduate curriculum, related to management of patients with a PIVC, is disjointed and inconsistent and this inconsistency may negatively impact patient safety.

Nursing students' knowledge on the management of peripheral venous catheters at Wollega University

BACKGROUND

Adherence to the best standards of nursing practice is the fundamental principle to improve patient outcome and prevent nursing procedure related-infections. A peripheral venous catheter (PVC) is the most common invasive procedure performed in nursing care. Its poor performance could expose patients to bloodstream-related infections. The present study aimed to assess post-basic nursing students' knowledge of evidence-based guidelines on the management of peripheral venous catheters.

METHODS

A cross-sectional study design was conducted on May 01-03, 2019, using a convenient sample 239 among post-basic nursing students in Wollega University.

RESULTS

The study result showed that nursing students' had a low mean (4.1±1.52) of knowledge about PVC procedure management. Only 41% of the respondents have adhered to recommendations of CDC guidelines. Among the provided options of the items, none achieved 100% correct answers. The majority of nursing students (77%) responded that antiseptic handwashing is always performed before insertion of PVCs. Meanwhile, few students (5%) correctly answered that the infusion set is recommended to be removed after 96 hours when neither lipids nor blood products are administered. In multivariable regression analysis, nursing students who had received training (AOR = 2.9, 95% CI (1.6, 5.1)) and who were younger (AOR = 2.4, 95% CI (1.3, 4.3)) significantly associated with a higher score of knowledge.

CONCLUSIONS

This study finding shows that an overall level of knowledge of post-basic nursing students is inadequate. Measurements such as an increase in the provision of adequate training by nurses educators based on evidence-based guidelines could improve the post-basic nursing students' knowledge.

Are current clinical guidelines on the use of Peripheral Intravenous Cannula for blood draws supported by evidence? An organizational case study

Aim

To examine the quality of evidence used to inform health policies. Policies on peripheral intravenous cannulas were used as exemplars.

Design

An organizational case study design was used, using the STROBE reporting guidelines.

Methods

Policy guidelines were sourced between June and September 2018 from health departments in Australia. Seven documents were compared regarding intravenous cannula dwell times and blood collection use. Evidence used in the documents was critiqued using assessment guideline from the Oxford Centre for Evidence Based Medicine.

Results

Large variations exist between policies regarding blood sampling and dwell time. Evidence used a variety of sources. Few references received an A evidence rating and policies differed in their interpretation of evidence.

Management of peripheral venous catheters and implementation of guidelines in Germany: a national survey

BACKGROUND

Due to their frequent use, peripheral venous catheters (PVCs) are of importance in terms of catheter-related infections and their prevention. In 2017, revised national guidelines for the prevention of PVC-related infections were published in Germany.

AIM

To describe PVC handling practices and assess the implementation of national guidelines for the prevention of PVC-related infections in German acute care hospitals, 10 months after their release.

METHODS

An online survey on the management of PVCs in hospital wards was conducted. For this, 1191 acute care hospitals participating in the national surveillance system for healthcare-associated infections in Germany were invited to participate. Each hospital was asked to complete the survey for an intensive care unit (ICU), as well as a medical ward and a surgical ward. Participation in the survey was voluntary.

FINDINGS

In total, 701 hospitals (response rate 59%) participated and provided data on 1449 wards (599 ICUs, 446 medical wards, 404 surgical wards). Approximately 43% of wards reported that they had implemented the new national guidelines where necessary. Structured surveillance for PVC-associated infections was established in only 21% of wards. While 94% of wards reported the inclusion of aspects of PVC handling in their general infection prevention education, questions on the training methods yielded diverse results. Approximately 59% of wards reported that they did not routinely use a combination of alcohol and a remanant disinfectant for skin disinfection before PVC insertion.

CONCLUSION

Generally, PVC management in Germany is well organized. However, potential for improvement was identified, particularly considering surveillance and implementation of selected national guidelines.

Point prevalence survey of peripheral venous catheter usage in a large tertiary care university hospital in Germany

Background

Bloodstream infections (BSI) are among the most frequently documented healthcare-associated infections (HAI). Central and peripheral venous catheters (CVC and PVC) are relevant risk factors for BSI. Although the risk for BSI is higher for CVC, PVC are utilized more frequently and are therefore relevant in the context of HAI prevention. Robust data on the prevalence of PVC and associated infections in German hospitals are scarce to this date. The objectives of this survey were to estimate the prevalence of PVC and PVC-associated infections on peripheral wards of a large tertiary care hospital in Germany. The collected data may be utilized for a tailored infection prevention intervention in the future.

Methods

A point prevalence survey was conducted on peripheral wards of a tertiary care hospital with more than 3.000 beds. Data were collected between August 2017 and February 2018. Standardized data collection forms were used for collecting ward, patient and PVC-related data. As endpoints, prevalence of patients with PVC, PVC-associated infections and PVC without usage in the 24 h prior to the survey and without documentation of intended usage in the 24 h after the survey ("unused PVC") were chosen. For data analysis, Kruskal-Wallis test was employed for continuous variables and Chi-squared test or Fisher's exact test for categorical variables. Multivariable analysis and logistic regression were performed for the endpoint unused PVC.

Results

Data from 2.092 patients on 110 wards were collected. The overall prevalence of patients with PVC was 33%. Infections were recorded in 16 patients. Except one case of BSI, these were all local infections at the site of insertion. Of 725 documented PVC, 77 (11%) were unused PVC. Multivariate analysis and logistic regression revealed wards with the practice of regularly obtaining blood from PVC, PVC with dirty or loose insertion dressing, pediatric ward specialty and last inspection of the PVC more than 1 day ago as significant risk factors for unused PVC.

Conclusions

A substantial proportion of patients presented with a PVC on the day of survey. Too few infections were recorded to allow for more detailed analyses. Various risk factors for unused PVC were identified. We hereby present a solid method to obtain an overview about PVC use and to increase awareness for PVC-associated risks. The limitations of point prevalence surveys have to be recognized.

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.
