Central venous catheterization (CVC) is a frequent procedure, practiced by intensivists, anesthesiologists and advanced practice nurses in intensive care units and operative rooms. To reduce CVC-associated morbidity, it is essential to strive for best practices, based on the latest evidence. This narrative review aims to synthesize current knowledge on evidence-based best practices for CVC that improve the use and feasibility of real-time ultrasound-guided insertion procedures. Optimization of the vein puncture technique and the development of new technologies are discussed to reinforce the use of the subclavian vein catheterization as first choice. The search for alternative site of insertions, without increasing infectious and thrombotic risks, deserves further research. [ABSTRACT FROM AUTHOR]

Aim: To test the feasibility of a study protocol that compared the efficacy of neutral‐ and negative‐pressure needleless connectors (NCs). Design: A single‐centre, parallel‐group, pilot randomised control trial. Methods: Our study compared neutral‐(intervention) and negative‐pressure (control) NCs among adult patients in an Australian hospital. The primary feasibility outcome was measured against predetermined criteria (e.g. eligibility, attrition). The primary efficacy outcome was all‐cause peripheral intravenous catheter failure, analysed as time‐to‐event data. Results: In total, 201 (100 control; 101 intervention) participants were enrolled between March 2020 and September 2020. All feasibility criteria were met except eligibility, which was lower (78%) than the 90% criterion. All‐cause peripheral intravenous catheter failure was significantly higher in the intervention group (39%) compared to control (19%). Conclusion: With minor modifications to participant screening for eligibility, this randomised control trial is feasible for a large multicentre randomised control trial. The neutral NC was associated with an increased risk of peripheral intravenous catheter failure. Implications for the Profession and/or Patient Care: There are several NC designs available, often identified by their mechanism of pressure (positive, negative and neutral). However, NCs can contribute to peripheral intravenous catheter failure. This is the first randomised controlled trial to compare neutral and negative NC designs. Negative pressure NCs had lower PIVC failure compared to neutral NCs, however the results might not be generalisable to other brands or treatment settings. Further high‐quality research is needed to explore NC design. Reporting Method: Study methods and results reported in adherence to the CONSORT Statement. Patient or Public Contribution: No patient or public contribution. [ABSTRACT FROM AUTHOR]

Aim: To synthesise evidence related to medical adhesive tapes and supplementary securement products for peripheral intravenous catheters in adults, to prevent complications and device failure. Design: Integrative review informed by Whittemore and Knafl and reported in accordance with the PRISMA 2020 statement. Data sources. The Cochrane Central Register of Controlled Trials, US National Library of Medicine National Institutes of Health, EMBASE/MEDLINE and Cumulative Index to Nursing and Allied Health were searched from 2000–21 September 2020. Review Methods. Studies enrolling hospitalised participants >16 years with peripheral intravenous catheters secured by medical adhesive tapes, or supplementary products (bandage, splint and sutureless securement device), were eligible. Quality appraisal was performed using Critical Appraisal Skills Program checklists. Results: Nineteen studies met criteria, including 43,683 peripheral intravenous catheters. Quality appraisal identified high or unclear risk of bias in 58% of studies. Nonsterile tape was the most common intervention tested (14 studies), alone or in multiproduct combinations. Nonsterile tape directly over insertion sites was associated with increased PIVC failure and complications. Sutureless securement devices potentially reduce failure and complications. Multiproduct combinations were very common. Practice recommendations regarding other tapes and secondary securement products are challenging, due to conflicting, or lack of, evidence. Conclusion: Tapes and secondary securement product evidence are limited, and over half of the studies are of low methodological quality. This review found nonsterile tape was associated with increased failure and complications; multiproduct dressing and securement bundles were prevalent; and significant evidence gaps exist particularly regarding bandages and splints. The results provide nurses with evidence of medical adhesive tapes and supplementary product effectiveness for peripheral intravenous catheter securement, and future research directions to reduce unacceptably high failure and complication rates. Larger rigorously conducted randomised controlled trials are needed to add to current evidence. [ABSTRACT FROM AUTHOR]

Background: Integrated peripheral intravenous catheters (PIVCs) demonstrate clinical efficacy, however, device complexity and design differences may be a potential barrier to implementation. Aims: To assess nurse acceptability of integrated PIVC systems. Methods: A cross-sectional survey was nested within a multicentre randomised controlled trial. One hundred nurses caring for patients with integrated and non-integrated PIVCs completed a 17-item survey about key differences between devices (eg function and appearance, perceived patient comfort and skin injuries). Findings: Most nurses reported the integrated PIVC wings prevented device movement (80%), achieved patient comfort in areas of flexion (78%), and no patients developed skin injuries (100%). Nurses rated the ease of accessing and overall confidence using the integrated PIVC as significantly higher than the non-integrated design (P<0.001).Conclusion: The integrated PIVC received positive feedback from nurses and had few barriers to implementation.

The optimal approach for peripheral intravenous catheter (PIVC) insertion in adult hospitalised patients with difficult intravenous access (DIVA) is unknown. The present study aimed to critically appraise the quality of (i) assessment instruments and (ii) clinical practice guidelines (CPGs) or escalation pathways for identifying and managing patients with DIVA. Cochrane Central Register of Controlled Trials, EBSCO MEDLINE, EMBASE (OVID) and EBSCO CINAHL databases were searched on 22 March 2021. Studies describing a DIVA assessment measure, CPG or escalation pathway for PIVC insertion in adults (≥18 years of age) were included. Data were extracted using a standardised data extraction form including study design, type of resource and reported clinical outcomes. Quality of DIVA assessment instruments were reviewed using the COnsensus‐based Standards for the selection of health Measurement Instruments checklist. Methodological quality of CPGs and escalation pathways was assessed using the Appraisal of Guidelines for Research and Evaluation‐II (AGREE‐II) instrument. Overall, 24 DIVA resources comprising 16 DIVA assessment instruments and nine CPGs or escalation pathways (including one combined assessment instrument and escalation pathway) were identified. Instruments commonly focused on vein visibility and palpability as indicators of DIVA. CPGs and escalation pathways unanimously recommended use of vessel visualisation technology for patients with or suspected of DIVA. Methodological quality of the resources was mixed. Consensus and standardisation of resources to identify DIVA and recommendations for managing patients with DIVA is limited. Adopting consistent, evidence‐based CPGs, escalation pathways or DIVA assessment instruments may significantly improve clinical outcomes. [ABSTRACT FROM AUTHOR]

Objective: To develop and validate a difficult intravenous access risk assessment and escalation pathway, to increase first time intravenous insertion success in paediatrics.Methods: Mixed methods underpinned by literature and co-production principles. Iterative development of the instrument was informed through semi-structured interviews and stakeholder workshops. The instrument includes a risk assessment, inserter skill self-assessment, and escalation pathways. Reproducibility, reliability, and acceptability were evaluated in a prospective cohort study at a quaternary paediatric hospital in Australia.Results: Interview data (three parents, nine clinicians) uncovered two themes: i) Recognition of children with DIVA and subsequent escalation is ad hoc and problematic; and ii) Resources and training impact inserter confidence and ability. Three workshops were delivered at monthly intervals (February-April 2020) involving 21 stakeholders culminating in the co-production of the "DIVA Key". The DIVA Key was evaluated between May-December 2020 in 78 children; 156 clinicians. Seventy-eight paired assessments were undertaken with substantial agreement (concordance range = 81.5 to 83.0%) between the assessors. Interrater reliability of the DIVA risk assessment was moderate (kappa = 0.71, 95% CI 0.63-0.80). The DIVA Key predicted multiple insertion attempts for red (high risk) DIVA classification (relative risk ratio 5.7, 95% CI 1.2-27.1; reference low risk). Consumer and clinician satisfaction with DIVA Key was high (median (IQR) = 10 [8-10]; 8 [8-10 respectively).Conclusion: The DIVA Key is a straightforward, reliable instrument with inbuilt escalation pathway to support the identification of children with difficult intravenous access.

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 laboratoryconfirmed 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. [ABSTRACT FROM AUTHOR]

The primary objective of this study was to identify the proportion of clinicians using ultrasound guidance (USG) to insert peripheral intravenous cannulas (PIVCs) in the emergency department (ED) following attendance at a hospital-based USG PIVC training program. Over 12-months, USG cannulation training sessions were offered to nurses and doctors competent in standard PIVC insertion (landmark technique), working in the ED. Surveys pre and post-training captured participants' self-reported confidence with cannulation and USG cannulation using a 5-point Likert scale. Supplemental data from observation periods before and after the trainings assessed departmental cannulation practices overall. Data were analysed using descriptive statistics and associations analysed using chi-square tests. Overall, 195 participants attended training; 58% completed follow-up surveys. Forty-three percent reported using USG cannulation the following month. The median confidence score amongst workshop participants increased from 1 to 3 (p <.001). Post-implementation, use of USG cannulation increased from 0.7% to 6.0% post-training (p <.001), although the overall number of attempts at PIVC placement did not change. USG cannulation training increased this practice in the short-term. However, no significant difference in the number of attempts was observed. Further investigation in controlled settings is needed to inform the widespread implementation of USG cannulation training packages. [ABSTRACT FROM AUTHOR]

Aim: To test the feasibility of an efficacy trial comparing different flushing frequencies and volumes to reduce peripheral intravenous cannula (PIVC) failure in paediatric inpatients.Methods: Pilot, 2 × 2 factorial, randomised controlled trial comparing PIVC flushing techniques in intervention pairs: (i) low volume (3 mL) versus high volume (10 mL); and (ii) low frequency (24 hourly) versus high frequency (6 hourly). Patients were excluded if: fluids were restricted, weight < 5 kg, PIVC already in situ for >24 h or continuous infusion. The primary end-point was feasibility (eligibility, recruitment, retention, protocol adherence, missing data and sample size estimates) of a large trial. Secondary end-points were PIVC failure (composite and individual), bloodstream infection and mortality.Results: A total of 919 children were screened from April to November 2015, with 55 enrolled. Screening feasibility criteria were not met, mainly due to continuous infusions and PIVCs in situ >24 h or planned for imminent removal. However, 80% of eligible participants consented, 2% withdrew, protocol adherence was 100%, and there was no missing primary end-point data. PIVC failure was significantly higher (hazard ratio = 2.90, 95% confidence interval: 1.11-7.54) in the 3 mL compared to the 10 mL group. There was no difference in failure between frequency groups (hazard ratio = 0.91, 95% confidence interval: 0.36-2.33). There was no interaction effect (P = 0.22).Conclusion: Trial feasibility proved challenging due to eligibility criteria, which could be improved with additional recruiting staff. Firm conclusions cannot be made based on this small sample, but flush volume may impact PIVC failure. [ABSTRACT FROM AUTHOR]

Background: Two billion peripheral intravenous catheters (PIVCs) are used globally each year, but optimal dressing and securement methods are not well established. We aimed to compare the efficacy and costs of three alternative approaches to standard non-bordered polyurethane dressings.Methods: We did a pragmatic, randomised controlled, parallel-group superiority trial at two hospitals in Queensland, Australia. Eligible patients were aged 18 years or older and required PIVC insertion for clinical treatment, which was expected to be required for longer than 24 h. Patients were randomly assigned (1:1:1:1) via a centralised web-based randomisation service using random block sizes, stratified by hospital, to receive tissue adhesive with polyurethane dressing, bordered polyurethane dressing, a securement device with polyurethane dressing, or polyurethane dressing (control). Randomisation was concealed before allocation. Patients, clinicians, and research staff were not masked because of the nature of the intervention, but infections were adjudicated by a physician who was masked to treatment allocation. The primary outcome was all-cause PIVC failure (as a composite of complete dislodgement, occlusion, phlebitis, and infection [primary bloodstream infection or local infection]). Analysis was by modified intention to treat. This trial is registered with the Australian New Zealand Clinical Trials Registry, number ACTRN12611000769987.Findings: Between March 18, 2013, and Sept 9, 2014, we randomly assigned 1807 patients to receive tissue adhesive with polyurethane (n=446), bordered polyurethane (n=454), securement device with polyurethane (n=453), or polyurethane (n=454); 1697 patients comprised the modified intention-to-treat population. 163 (38%) of 427 patients in the tissue adhesive with polyurethane group (absolute risk difference -4·5% [95% CI -11·1 to 2·1%], p=0·19), 169 (40%) of 423 of patients in the bordered polyurethane group (-2·7% [-9·3 to 3·9%] p=0·44), 176 (41%) of 425 patients in the securement device with poplyurethane group (-1·2% [-7·9% to 5·4%], p=0·73), and 180 (43%) of 422 patients in the polyurethane group had PIVC failure. 17 patients in the tissue adhesive with polyurethane group, two patients in the bordered polyurethane group, eight patients in the securement device with polyurethane group, and seven patients in the polyurethane group had skin adverse events. Total costs of the trial interventions did not differ significantly between groups.Interpretation: Current dressing and securement methods are commonly associated with PIVC failure and poor durability, with simultaneous use of multiple products commonly required. Cost is currently the main factor that determines product choice. Innovations to achieve effective, durable dressings and securements, and randomised controlled trials assessing their effectiveness are urgently needed.Funding: Australian National Health and Medical Research Council.

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.

Background: Peripherally inserted central catheters (PICCs) are commonly used for delivering intravenous therapy. PICC failure is unacceptably high (up to 40%) due to mechanical, infectious and thrombotic complications. Poor securement potentiates all complication types. This randomised controlled trial (RCT) aimed to examine the feasibility of a large RCT of four dressing and securement methods to prevent PICC failure.Methods: This single-centre pilot RCT included 124 admitted medical/surgical/cancer patients aged ≥ 16 years with a PICC. Interventions were: (i) standard polyurethane dressing and sutureless securement device (SPU + SSD, control); (ii) polyurethane with absorbent lattice pad dressing (PAL + Tape); (iii) combination securement-dressing (CSD); and (iv) tissue adhesive (TA + SPU). All groups except TA + SPU had a chlorhexidine-gluconate (CHG) impregnated disc. Feasibility outcomes were recruitment and safety/acceptability of the interventions. The primary outcome was PICC failure, a composite of PICC removal for local infection, catheter-associated bloodstream infection, dislodgement, occlusion, and/or catheter fracture. Secondary outcomes included individual complications, dressing failure and dwell time, PICC dwell time, skin complications/phlebitis indicators, product costs, and patient and staff satisfaction. Qualitative feedback was also collected.Results: PICC failure incidence was: PAL + CHG + Tape (1/5; 20%; 17.4/1000 days), SPU + SSD + CHG (control) (4/39; 10%; 9.0/1000 days), TA + SPU (3/35; 9%; 9.6/1000 days), and CSD + CHG (3/42; 7%; 9.4/1000 days). Recruitment to PAL + CHG + Tape was ceased after five participants due to concerns of PICC dislodgement when removing the dressing. CSD + CHG, TA + SPU (TA applied only at PICC insertion time), and control treatments were acceptable to patients and health professionals.Conclusion: A large RCT of CSD + CHG and TA + SPU (but not PAL + CHG + Tape) versus standard care is feasible.Trial Registration: Australian and New Zealand Clinical Trials Registry, ACTRN12616000027415 .

Objective Failed attempts at peripheral i.v. cannula ( PIVC) insertion in the ED are common. The psychological, physical and economic impact of these failures is significant. We sought to explore whether clinicians of differing experience levels can predict their own likelihood (clinician 'gestalt') of first-time cannula insertion success on any given patient. Methods Data analyses from a prospective self-reported study assessing risk factors for first-time insertion success in a tertiary adult ED. We constructed and compared two simple theoretical clinical decision algorithms in an attempt to improve first-time PIVC insertion success rates. Results This best algorithm identified a subgroup of 18% of the total PIVC population at higher risk of failure. This 18% comprised 57% of all PIVC failures, and implementation would result in a relative risk reduction of PIVC failure by 31%. Conclusions When applied to our sample population, an algorithm relying on clinician gestalt to identify patients at high risk of PIVC failure had the greatest potential impact. These patients would be referred to expert PIVC inserters prior to, rather than after, failed attempts. [ABSTRACT FROM AUTHOR]

Background: Peripheral vascular catheters (PVC) are the most frequently used invasive medical devices in hospitals, with 330 million sold each year in the USA alone. One in three UK inpatients at any one time has at least one PVC in situ according to the Scottish National Prevalence survey. Method: A narrative review of studies describing the infection risks associated with PVCs. Results: It is estimated that 30–80% of hospitalised patients receive at least one PVC during their hospital stay. Despite their prevalence, PVCs are not benign devices, and the high number of PVCs inserted annually has resulted in serious catheter-related bloodstream infections and significant morbidity, prolonged hospital stay and increased healthcare system costs. To date, PVC infections have been under-evaluated. Most studies focus on central venous catheter rather than PVC-associated bloodstream infections. Risks associated with PVC infection must be addressed to reduce patient morbidity and associated costs of prolonged hospital admission and treatment. Discussion: This article discusses the sources and routes of PVC-associated infection and outlines known effective prevention and intervention strategies. [ABSTRACT FROM AUTHOR]

Skin bacteria at peripheral intravenous catheter (PIVC) insertion sites pose a serious risk of microbial migration and subsequent colonisation of PIVCs, and the development of catheter related bloodstream infections (CRBSIs). Common skin bacteria are often associated with CRBSIs, therefore the bacterial communities at PIVC skin sites are likely to have major implications for PIVC colonisation. This study aimed to determine the bacterial community structures on skin at PIVC insertion sites and to compare the diversity with associated PIVCs. A total of 10 PIVC skin site swabs and matching PIVC tips were collected by a research nurse from 10 hospitalised medical/surgical patients at catheter removal. All swabs and PIVCs underwent traditional culture and high-throughput sequencing. The bacterial communities on PIVC skin swabs and matching PIVCs were diverse and significantly associated (correlation coefficient = 0.7, p<0.001). Methylobacterium spp. was the dominant genus in all PIVC tip samples, but not so for skin swabs. Sixty-one percent of all reads from the PIVC tips and 36% of all reads from the skin swabs belonged to this genus. Staphylococcus spp., (26%), Pseudomonas spp., (10%) and Acinetobacter spp. (10%) were detected from skin swabs but not from PIVC tips. Most skin associated bacteria commonly associated with CRBSIs were observed on skin sites, but not on PIVCs. Diverse bacterial communities were observed at skin sites despite skin decolonization at PIVC insertion. The positive association of skin and PIVC tip communities provides further evidence that skin is a major source of PIVC colonisation via bacterial migration but microbes present may be different to those traditionally identified via culture methods. The results provide new insights into the colonisation of catheters and potential pathogenesis of bacteria associated with CRBSI, and may assist in developing new strategies designed to reduce the risk of CRBSI.

Rationale, aims and objectives Many peripheral intravenous catheter ( PIVC) infusion phlebitis scales and definitions are used internationally, although no existing scale has demonstrated comprehensive reliability and validity. We examined inter-rater agreement between registered nurses on signs, symptoms and scales commonly used in phlebitis assessment. Methods Seven PIVC-associated phlebitis signs/symptoms (pain, tenderness, swelling, erythema, palpable venous cord, purulent discharge and warmth) were observed daily by two raters (a research nurse and registered nurse). These data were modelled into phlebitis scores using 10 different tools. Proportions of agreement (e.g. positive, negative), observed and expected agreements, Cohen's kappa, the maximum achievable kappa, prevalence- and bias-adjusted kappa were calculated. Results Two hundred ten patients were recruited across three hospitals, with 247 sets of paired observations undertaken. The second rater was blinded to the first's findings. The Catney and Rittenberg scales were the most sensitive (phlebitis in >20% of observations), whereas the Curran, Lanbeck and Rickard scales were the most restrictive (≤2% phlebitis). Only tenderness and the Catney (one of pain, tenderness, erythema or palpable cord) and Rittenberg scales (one of erythema, swelling, tenderness or pain) had acceptable (more than two-thirds, 66.7%) levels of inter-rater agreement. Conclusions Inter-rater agreement for phlebitis assessment signs/symptoms and scales is low. This likely contributes to the high degree of variability in phlebitis rates in literature. We recommend further research into assessment of infrequent signs/symptoms and the Catney or Rittenberg scales. New approaches to evaluating vein irritation that are valid, reliable and based on their ability to predict complications need exploration. [ABSTRACT FROM AUTHOR]

Objective Children admitted to hospital commonly require peripheral intravenous catheters ( PIVCs) for treatment. This study sought to address a gap in the literature about current practice in the securement and dressing of PIVCs in paediatric acute care, and to ascertain the duration and failure of these devices. Methods A prospective cohort study conducted at the Royal Children's Hospital in Queensland, Australia. All patients aged 0-15 years, who presented to the ED between 16 July and 16 October 2012, and had a PIVC inserted prior to emergent admission to the hospital were included. Results Of 458 participants, median device duration was 29 h ( IQR 13-58 h), and ranged from less than 1 h to 16 days. One quarter (113/456, 24.8%) of PIVCs were removed due to device failure, presenting as: infiltration (65/456, 14.3%); accidental dislodgement (23/456, 5.0%); blockage (12/456, 2.6%); phlebitis (7/456, 1.5%); or 'other' (6/456, 1.3%). PIVC securement and dressings were predominantly bordered polyurethane dressings and splints ( n = 457/458, 99.8%). PIVC placement in the antecubital fossa, in comparison to the hand, was significantly associated with an increased risk for failure ( P = 0.03). No other patient and device characteristics had a significant association with device failure ( P > 0.05). The median dwell time of PIVCs that failed was significantly longer than the PIVCs that did not fail (44.0 vs 25.5 h; P = 0.002). Less than half (53/113, 46.9%) of failed catheters were replaced with a new PIVC. Conclusions Observed failure rates were high for a clinically essential device; however, there is no established rate of acceptability against which the results can be benchmarked against to facilitate effectiveness of practice. Many PIVCs appeared to remain in place longer than needed. Dressing and securement practice was homogenous. PIVC placement in the antecubital fossa should be minimised to reduce the risk of paediatric PIVC failure. [ABSTRACT FROM AUTHOR]

To compare colonization and catheter-related bloodstream infection (CR-BSI) rates among three insertion sites (subclavian, internal jugular, femoral) used for central venous catheter (CVC) placement. Twenty-four-month prospective study, with relative effects analyzed by Cox proportional hazards regression. Eight-bed intensive care unit. Four hundred and ten critically ill patients requiring CVC placement. All short-term multi-lumen CVCs, including antimicrobial-coated devices, were studied with management standardized. Six hundred and five CVCs (4,040 catheter days) were analyzed. Colonization and CR-BSI incidence were, respectively, 15.1 (95% CI 13.5–21.0) and 1.8 (95% CI 1.2–4.2) per 1,000 catheter-days. Colonization was higher at the internal jugular (HR 3.64; 95% CI 1.32–10.00; p = 0.01) and femoral (HR 5.15; 95% CI 1.82–14.51; p = 0.004) sites than at the subclavian site. The femoral site carried a greater risk of being colonized by non- S. epidermidis species than the subclavian and internal jugular sites combined (HR 4.15; 95% CI 1.79–9.61; p = 0.001). CVCs inserted in the Department of Emergency Medicine were more colonized than those inserted in the ICU or operating room (HR 2.66; 95% CI 1.27–5.56; p = 0.01), and CVCs were less colonized in females than in males (HR 0.49; 95% CI 0.26–0.89; p = 0.02). No difference in CR-BSI rates was noted between the three sites. Colonization was lowest at the subclavian site. Regional differences exist with respect to type of pathogen isolated. Colonization was influenced by insertion location and gender. The incidence of CR-BSI was not different. [ABSTRACT FROM AUTHOR]

Background: Peripheral intravenous catheters (PIVCs) are ubiquitous medical devices, crucial to providing essential fluids and drugs. However, post-insertion PIVC failure occurs frequently, likely due to inconsistent maintenance practice such as flushing. The aim of this implementation study was to evaluate the impact a multifaceted intervention centred on short PIVC maintenance had on patient outcomes.Methods: This single-centre, incomplete, stepped wedge, cluster randomised trial with an implementation period was undertaken at a quaternary hospital in Queensland, Australia. Eligible patients were from general medical and surgical wards, aged ≥ 18 years, and requiring a PIVC for > 24 h. Wards were the unit of randomisation and allocation was concealed until the time of crossover to the implementation phase. Patients, clinicians, and researchers were not masked but infections were adjudicated by a physician masked to allocation. Practice during the control period was standard care (variable practice with manually prepared flushes of 0.9% sodium chloride). The intervention group received education reinforcing practice guidelines (including administration with manufacturer-prepared pre-filled flush syringes). The primary outcome was all-cause PIVC failure (as a composite of occlusion, infiltration, dislodgement, phlebitis, and primary bloodstream or local infection). Analysis was by intention-to-treat.Results: Between July 2016 and February 2017, 619 patients from 9 clusters (wards) were enrolled (control n = 306, intervention n = 313), with 617 patients comprising the intention-to-treat population. PIVC failure was 91 (30%) in the control and 69 (22%) in the intervention group (risk difference - 8%, 95% CI - 14 to - 1, p = 0.032). Total costs were lower in the intervention group. No serious adverse events related to study intervention occurred.Conclusions: This study demonstrated the effectiveness of post-insertion PIVC flushing according to recommended guidelines. Evidence-based education, surveillance and products for post-insertion PIVC management are vital to improve patient outcomes.Trial Registration: Trial submitted for registration on 25 January 2016.

Background: The reported incidence of peripheral intravenous catheter (PIV) failure has been as high as 69%. This is in part due to inadequate stabilisation or securement to the skin, which allows micro-motion of the catheter within the vein.Methods: A pilot open randomised controlled trial of 300 patients was conducted in the medical and surgical wards of a large tertiary hospital. A superiority parallel pragmatic design was used. Eligible patients over the age of 16 years were randomised using a centralised service (randomly varied block sizes and 1:1 ratio) to have PIV dressings of either (i) a bordered polyurethane dressing (BPU, standard care) or (ii) the integrated securement device (ISD). Allocation was concealed until entry. The primary outcome of feasibility addressed eligibility, consent, protocol adherence and retention rates. All-cause PIV failure was an additional primary outcome. This was a composite of infection (laboratory-confirmed local or bloodstream infection), occlusion or infiltration, dislodgement, phlebitis and thrombosis. Group comparisons were by proportions, incidence rates per 1000 PIV days and hazard ratios. Secondary outcomes were local or bloodstream infection, occlusion or infiltration, dislodgement, phlebitis, thrombosis, PIV dwell time, safety and adverse events and patient satisfaction with study products. Analysis was by intention to treat and the patient was the unit of measurement. Multivariable modelling was undertaken.Results: Feasibility outcomes were 91% of screened patients were eligible, 98% of invited patients consented, 100% of randomised participants received the allocated intervention on insertion and 1/300 (< 1%) were lost to follow-up. In total, 792 PIV days were studied. PIV failure occurred in 43/150 BPU patients (29%) and 40/150 ISD patients (27%) (119 vs 93 per 1000 PIV days; incidence rate ratio 0.78, 95% confidence interval, CI 0.50-1.23). In the multivariate model, ISD (hazard ratio 0.51, 95% CI 0.29-0.89) and admission for a surgical emergency were significantly associated with decreased failure, while female gender, wound, hand insertion and more frequent PIV use were significantly associated with increased PIV failure.Conclusion: ISDs were significantly associated with decreased failure in the multivariable modelling. Feasibility outcomes were supportive of the need to undertake a larger trial to confirm these results.Trial Registration: Australian New Zealand Clinical Trials Registry, ACTRN12616000984493 .

Improving the safety and quality of health care relies on implementing evidence-based findings into every-day clinical practice. Numerous clinical decision aids have been developed to guide nursing care of the patient with a peripheral intravenous catheter (PIVC), including standards, guidelines, decision frameworks, bundles, policies, procedures, algorithms, pathways, checklists and scoring tools. While all are created with the intention of facilitating the delivery of safe, effective nursing care and improving patient outcomes, there are distinct differences in methodology and design between them, and many are based on expert opinion and historical practice rather than high-quality evidence. This paper reviews the types of decision aids for daily PIVC assessment and management, explores the evidence base underpinning them, and considers the implications for their use in clinical practice. A consistent, systematic and evidence-based approach to PIVC care will provide the optimal environment for achieving quality patient outcomes. [ABSTRACT FROM AUTHOR]

Peripheral intravenous catheters are the most frequently used invasive device in nursing practice, yet are commonly associated with complications. We performed a systematic review to determine the prevalence of peripheral intravenous catheter infection and all-cause failure. The Cochrane Library, PubMed, CINAHL, and EMBASE were searched for observational studies and randomised controlled trials that reported peripheral intravenous catheter related infections or failure. The review was limited to English language and articles published from the year 2000. Pooled estimates were calculated with random-effects models. Meta-analysis of observation studies in epidemiology guidelines and the Cochrane process for randomised controlled trials were used to guide the review. Prospero registration number: CRD42022349956. Our search retrieved 34,725 studies. Of these, 41 observational studies and 28 randomised controlled trials (478,586 peripheral intravenous catheters) met inclusion criteria. The pooled proportion of catheter-associated bloodstream infections was 0.028 % (95 % confidence interval (CI): 0.009–0.081; 38 studies), or 4.40 catheter-associated bloodstream infections per 100,000 catheter-days (20 studies, 95 % CI: 3.47–5.58). Local infection was reported in 0.150 % of peripheral intravenous catheters (95 % CI: 0.047–0.479, 30 studies) with an incidence rate of 65.1 per 100,000 catheter-days (16 studies; 95 % CI: 49.2–86.2). All cause peripheral intravenous catheter failure before treatment completion occurred in 36.4 % of catheters (95 % CI: 31.7–41.3, 53 studies) with an overall incidence rate of 4.42 per 100 catheter days (78,891 catheter days; 19 studies; 95 % CI: 4.27–4.57). Peripheral intravenous catheter failure is a significant worldwide problem, affecting one in three catheters. Per peripheral intravenous catheter, infection occurrence was low, however, with over two billion catheters used globally each year, the absolute number of infections and associated burden remains high. Substantial and systemwide efforts are needed to address peripheral intravenous catheter infection and failure and the sequelae of treatment disruption, increased health costs and poor patient outcomes.

Background Peripheral venous catheterisation is the most frequent invasive procedure performed in hospitalised patients; yet over 30% of peripheral venous catheters fail before treatment ends. Objectives To assess the effects of peripheral venous catheter dressings and securement devices on the incidence of peripheral venous catheter failure. Data sources We searched the Cochrane Wounds Group Register, The Cochrane Central Register of Controlled Trials, MEDLINE; EMBASE and CINAHL for any randomised controlled trials comparing different dressings or securement devices used to stabilise peripheral venous catheters. The reference lists of included studies were also searched for any previously unidentified studies. Results We included six randomised controlled trials (1539 participants) that compared various dressings and securement devices (transparent dressings versus gauze; bordered transparent dressings versus a securement device; bordered transparent dressings versus tape; and transparent dressing versus sticking plaster). Trial sizes ranged from 50 to 703 participants. The quality of evidence ranged from low to very low. Catheter dislodgements or accidental removals were lower with transparent dressings compared with gauze (two studies, 278 participants, risk ratio (RR) 0.40; 95% confidence interval (CI) 0.17–0.92, P = 0.03%). However, the relative effects of transparent dressings and gauze on phlebitis (RR 0.89; 95% CI 0.47–1.68) and infiltration (RR 0.80; 95% CI 0.48–1.33) are unclear. A single study identified less frequent dislodgement or accidental catheter removal with bordered transparent dressings compared to a securement device (RR 0.14, 95% CI 0.03–0.63) but more phlebitis with bordered dressings (RR 8.11, 95% CI 1.03–64.02). A comparison of a bordered transparent dressing and tape found more peripheral venous catheter failure with the bordered dressing (RR 1.84, 95% CI 1.08–3.11) but the relative effect on dislodgement was unclear. Conclusions There is no strong evidence to suggest that any one dressing or securement product for preventing peripheral venous catheter failure is more effective than any other product. All of the included trials were small, had high or unclear risk of bias for one or more of the quality elements we assessed, and wide confidence intervals, indicating that further randomised controlled trials are necessary. There is a need for suitably powered, high quality trials to evaluate the newer, high use products and novel – but expensive – securement methods, such as surgical grade glue. [ABSTRACT FROM AUTHOR]

Background Up to 85% of hospital in-patients will require some form of vascular access device to deliver essential fluids, drug therapy, nutrition and blood products, or facilitate sampling. The failure rate of these devices is unacceptably high, with 20–69% of peripheral intravenous catheters and 15–66% of central venous catheters failing due to occlusion, depending on the device, setting and population. A range of strategies have been developed to maintain device patency, including intermittent flushing. However, there is limited evidence informing flushing practice and little is known about the current flushing practices. Objective The aim of the study was to improve our understanding of current flushing practices for vascular access devices through a survey of practice. Method A cross-sectional survey of nurses and midwives working in the State of Queensland, Australia was conducted using a 25-item electronic survey that was distributed via the local union membership database. Results A total of 1178 surveys were completed and analysed, with n = 1068 reporting peripheral device flushing and n = 584 reporting central device flushing. The majority of respondents were registered nurses (55%) caring for adult patients (63%). A large proportion of respondents (72% for peripheral, 742/1028; 80% for central, 451/566) were aware of their facility's policy for vascular access device flushing. Most nurses reported using sodium chloride 0.9% for flushing both peripheral (96%, 987/1028) and central devices (75%, 423/566). Some concentration of heparin saline was used by 25% of those flushing central devices. A 10-mL syringe was used by most respondents for flushing; however, 24% of respondents used smaller syringes in the peripheral device group. Use of prefilled syringes (either commercially prepared sterile or prefilled in the workplace) was limited to 10% and 11% respectively for each group. The frequency of flushing varied widely, with the most common response being pro re nata (23% peripheral and 21% central), or 6 hourly (23% peripheral and 22% central). Approximately half of respondents stated that there was no medical order or documentation for either peripheral or central device flushing. Conclusions Flushing practices for vascular access device flushing appear to vary widely. Specific areas of practice that warrant further investigation include questions about the efficacy of heparin for central device flushing, increasing adherence to the recommended 10 mL diameter syringe use, increased use of prefilled flush syringes, identifying and standardising optimal volumes and frequency of flushing, and improving documentation of flush orders and administration.

Peripheral intravenous catheters are an essential medical device which are prone to complications and failure. Identify patient, provider and device risk factors associated with all-cause peripheral intravenous catheter failure as well as individual complications: phlebitis, infiltration/occlusion, and dislodgement to improve patient outcomes. Secondary analysis of twelve prospective studies performed between 2008 and 2020. Australian metropolitan and regional hospitals including one paediatric hospital. Participants were from medical, surgical, haematology, and oncology units. Multilevel mixed-effects parametric survival regression was used to identify factors associated with all-cause peripheral intravenous catheter failure, phlebitis, occlusion/infiltration, and dislodgement. We studied patient (e.g., age, gender), device (e.g., gauge), and provider (e.g., inserting clinician) variables. Stepwise regression involved clinically and p <0.20 significant variables entered into the multivariable model. Results were expressed as hazard ratios (HRs) and 95% confidence intervals (CI); p <0.01 was considered statistically significant. Of 11,830 peripheral intravenous catheters (8,200 participants) failure occurred in 36% (n = 4,263). Occlusion/infiltration incidence was 23% (n = 2,767), phlebitis 12% (n = 1,421), and dislodgement 7% (n = 779) of catheters. Patient factors significantly associated with failure and complications were: female gender (phlebitis; (HR 1.98, 95% CI 1.72–2.27), (infiltration/occlusion; HR 1.45, 95% CI 1.33–1.58), (failure; HR 1.36, 95% CI 1.26–1.46); and each year increase in age (phlebitis; 0.99 HR, 95% CI 0.98–0.99), (failure; 0.99 HR, 95% CI 0.99–0.99). The strongest provider risk factor was intravenous antibiotics (infiltration/occlusion; HR 1.40, 95% CI 1.27–1.53), (phlebitis; HR 1.36, 95% CI 1.18–1.56), (failure; HR 1.26, 95% CI 1.17–1.36). Catheters inserted by vascular access teams were less likely to dislodge (HR 0.53, 95% CI 0.42–0.67). Device risk factors most associated with all-cause failure were wrist/hand (HR 1.34, 95% CI 1.23–1.46), antecubital fossa peripheral intravenous catheters (HR 1.29, 95% CI 1.16–1.44) and 22/24 gauge (HR 1.27, 95% CI 1.12–1.45) catheters. Factors identified, including the protective aspect of vascular access team insertion, and high catheter failure associated with intravenous antibiotic administration, will allow targeted updates of peripheral intravenous catheter guidelines and models of care.
