How often are infusion sets for central venous catheters changed in Australian and New Zealand Intensive Care Units? A point prevalence survey

BACKGROUND

Infusion sets (comprising the tubing, measuring burettes, fluid containers, transducers) that are connected to invasive vascular devices are changed on a regular basis in an effort to reduce bacterial colonisation and bloodstream infection. There is a balance between reducing infection and creating unnecessary waste. Current evidence suggests that for central venous catheters (CVCs), changing infusion sets at 7 days does not increase infection risks.

OBJECTIVES

The objective of this study was to describe the current unit guidelines in Australian and New Zealand intensive care units (ICUs) for changing infusion sets for CVCs.

METHODS

prospective cross-sectional point prevalence study, as a part of the 2021 Australian and New Zealand Intensive Care Society Point Prevalence Program.

PARTICIPANTS

Australia and New Zealand (ANZ) adult ICUs and their patients on the day of the study.

RESULTS

Data were collected from 51 ICUs across ANZ. One-third of these (16/49) ICUs had a guideline that specified a 7-day replacement period, with the rest having a more frequent replacement period.

CONCLUSION

Most ICUs participating in this survey had policies to change their CVC infusion tubing in 3-4 days, and recent high-level evidence supports an update to extend this to 7 days. There remains work to be done to spread this evidence to ANZ ICUs and improve environmental sustainability initiatives.

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.

An mHealth application for chronic vascular access: A multi-method evaluation

BACKGROUND

Healthcare consumers require diverse resources to assist their navigation of complex healthcare interactions, however, these resources need to be fit for purpose.

AIM

In this study, we evaluated the utility, usability and feasibility of children, families and adults requiring long-term intravenous therapy using a recently developed mobile health application (App), intravenous (IV) Passport.

DESIGN

Multi-site, parallel, multi-method, prospective cohort study.

METHODS

A multi-site, multi-method study was carried out in 2020-2021, with 46 participants (20 adults, 26 children/family) reporting on their experiences surrounding the use of the IV Passport for up to 6 months.

RESULTS

Overall, utility rates were acceptable, with 78.3% (N = 36) using the IV Passport over the follow-up period, with high rates of planned future use for those still active in the project (N = 21; 73%), especially in the child/family cohort (N = 13; 100%). Acceptability rates were high (9/10; IQR 6.5-10), with the IV Passport primarily used for documenting new devices and complications. Thematic analysis revealed three main themes (and multiple subthemes) in the qualitative data: Advocacy for healthcare needs, Complexity of healthcare and App design and functionality.

CONCLUSION

Several recommendations were made to improve the end-user experience including 'how to' instructions; and scheduling functionality for routine care.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

The IV Passport can be safely and appropriately integrated into healthcare, to support consumers.

IMPACT

Patient-/parent-reported feedback suggests the Intravenous Passport is a useful tool for record-keeping, and positive communication between patients/parents, and clinicians.

REPORTING METHOD

Not applicable.

PATIENT CONTRIBUTION

Consumers reported their experiences surrounding the use of the IV Passport for up to 6 months.

Perioperative arterial catheterization: A prospective evaluation of ultrasound, infection, and patient-focused outcomes

BACKGROUND

There is little information regarding complications of arterial catheterization in modern clinical care. We aimed to determine the incidence of abnormal duplex vascular ultrasound and catheter related infections following perioperative arterial catheterization.

METHODS

Patients requiring arterial catheterization for elective surgery were included and insertion details collected prospectively. Duplex ultrasound evaluation was performed 24 h after catheter removal. Symptomatic patients were identified by self-reported questionnaire. On Day 7, patients answered questions by telephone, related to the insertion site, pain, and function. Results of catheter tip and blood culture analyses were sought. Univariate associations of patient and surgical characteristics with abnormal ultrasound were assessed with p < 0.05 considered significant.

RESULTS

Of 339 catheterizations, 105 (40%) had ultrasound evaluation. Catheters were indwelling for median (IQR, range) duration of 6.0 h (4.4-8.2, 1.8-28) with no catheter-related infections. There were 16 (15.2%, 95% CI 9.0%-23.6%) abnormal results, including 14 radial artery thromboses, one radial artery dissection, and one radial vein thrombosis. Those with abnormal ultrasound results were more likely to have had Arrow catheters inserted (68.8% vs 27%, p = 0.023) and more than one skin puncture (37.5% vs 26.8%, p = 0.031). Two of the 16 (12.5%) patients with abnormal ultrasound results reported new symptoms related to the hand compared with nine of the 88 (10.2%) with normal results (p = 0.1). No patients required urgent referral for management.

CONCLUSIONS

Thrombosis was the most common abnormality and was usually asymptomatic. There were no infections, few post-operative symptoms, and minimal functional impairment following arterial catheterization.

Central Venous Access Device-Associated Skin Complications in Adults with Cancer: A Prospective Observational Study

OBJECTIVES

To identify the prevalence and type of central venous access device-associated skin complications for adult cancer patients, describe central venous access device management practices, and identify clinical and demographic characteristics associated with risk of central venous access device-associated skin complications.

METHODS

A prospective cohort study of 369 patients (626 central venous access devices; 7,682 catheter days) was undertaken between March 2017 and March 2018 across two cancer care in-patient units in a large teaching hospital.

RESULTS

Twenty-seven percent (n = 168) of participants had a central venous access device-associated skin complication. In the final multivariable analysis, significant (P < .05) risk factors for skin complications were cutaneous graft versus host disease (2.1 times greater risk) and female sex (1.4 times greater risk), whereas totally implanted vascular access device reduced risk for skin complications by two-thirds (incidence risk ratio 0.37).

CONCLUSION

Central venous access device-associated skin complications are a significant, potentially avoidable injury, requiring cancer nurses to be aware of high-risk groups and use evidence-based preventative and treatment strategies.

IMPLICATIONS FOR PRACTICE

This study has confirmed how common these potentially preventable injuries are. Therefore, the prevalence of these complications could be reduced by focusing on improvements in skin assessment, reductions in central venous access device dressing variation and improving clinician knowledge of this injury.

Risk factors for arterial catheter failure and complications during critical care hospitalisation: a secondary analysis of a multisite, randomised trial

OBJECTIVES

Arterial catheters (ACs) are critical for haemodynamic monitoring and blood sampling but are prone to complications. We investigated the incidence and risk factors of AC failure.

METHODS

Secondary analysis of a multi-centre randomised controlled trial (ACTRN 12610000505000). Analysis included a subset of adult intensive care unit patients with an AC. The primary outcome was all-cause device failure. Secondary outcomes were catheter associated bloodstream infection (CABSI), suspected CABSI, occlusion, thrombosis, accidental removal, pain, and line fracture. Risk factors associated with AC failure were investigated using Cox proportional hazards and competing-risk models.

RESULTS

Of 664 patients, 173 (26%) experienced AC failure (incidence rate [IR] 37/1000 catheter days). Suspected CABSI was the most common failure type (11%; IR 15.3/1000 catheter days), followed by occlusion (8%; IR 11.9/1,000 catheter days), and accidental removal (4%; IR 5.5/1000 catheter days). CABSI occurred in 16 (2%) patients. All-cause failure and occlusion were reduced with ultrasound-assisted insertion (failure: adjusted hazard ratio [HR] 0.43, 95% CI 0.25, 0.76; occlusion: sub-HR 0.11, 95% CI 0.03, 0.43). Increased age was associated with less AC failure (60-74 years HR 0.63, 95% CI 0.44 to 0.89; 75 + years HR 0.36, 95% CI 0.20, 0.64; referent 15-59 years). Females experienced more occlusion (adjusted sub-HR 2.53, 95% CI 1.49, 4.29), while patients with diabetes had less (SHR 0.15, 95% CI 0.04, 0.63). Suspected CABSI was associated with an abnormal insertion site appearance (SHR 2.71, 95% CI 1.48, 4.99).

CONCLUSIONS

AC failure is common with ultrasound-guided insertion associated with lower failure rates. Trial registration Australian New Zealand Clinical Trial Registry (ACTRN 12610000505000); date registered: 18 June 2010.

Handheld Ultrasound Devices for Peripheral Intravenous Cannulation: A Scoping Review

Ultrasound-guided insertion of peripheral intravenous catheters (PIVCs) is recommended for patients with difficult intravenous access, but access to ultrasound equipment is often limited to specialty departments. Compact, affordable handheld ultrasound devices are available, but the extent of their clinical adoption and impact on patient outcomes is unknown. This scoping review aimed to explore evidence regarding handheld and pocket ultrasound devices for PIVC insertion. Databases were searched for studies published in English between January 2000 and January 2023 evaluating handheld or pocket ultrasound devices weighing ≤3 kg for PIVC insertion. Data were extracted using standardized forms and summarized using descriptive statistics. Seventeen studies reporting the use of handheld or pocket ultrasound devices were identified. Most studies were conducted in adult inpatient facilities; 3 included pediatrics, and 2 reported out-of-hospital use. Participants with difficult intravenous access featured in 9 studies. Ultrasound training programs were described in 12 studies, with competency defined by number of successful PIVC insertions. Five studies reported clinician and/or patient perspectives. Ultrasound for PIVC insertion is not widely accessible in nonspecialist areas, but more compact and affordable handheld models could provide a solution, especially for patients with difficult access. More research evidence using handheld ultrasound is needed.

Peripheral intravenous catheter infection and failure: A systematic review and meta-analysis

BACKGROUND

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.

METHODS

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.

FINDINGS

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).

INTERPRETATION

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.

Health-related quality of life and experience measures, to assess patients' experiences of peripheral intravenous catheters: a secondary data analysis

BACKGROUND

Peripheral intravenous catheters (PIVCs) are essential for successful administration of intravenous treatments. However, insertion failure and PIVC complications are common and negatively impact patients' health-outcomes and experiences. We aimed to assess whether generic (not condition-specific) quality of life and experience measures were suitable for assessing outcomes and experiences of patients with PIVCs.

METHODS

We undertook a secondary analysis of data collected on three existing instruments within a large randomised controlled trial, conducted at two adult tertiary hospitals in Queensland, Australia. Instruments included the EuroQol Five Dimension - Five Level (EQ5D-5L), the Functional Assessment of Chronic Illness Therapy - Treatment Satisfaction - General measure (FACIT-TS-G, eight items), and the Australian Hospital Patient Experience Question Set (AHPEQS, 12 items). Responses were compared against two clinical PIVC outcomes of interest: all-cause failure and multiple insertion attempts. Classic descriptives were reported for ceiling and floor effects. Regression analyses examined validity (discrimination). Standardised response mean and effect size (ES) assessed responsiveness (EQ5D-5L, only).

RESULTS

In total, 685 participants completed the EQ5D-5L at insertion and 526 at removal. The FACIT-TS-G was completed by 264 and the AHPEQS by 262 participants. Two FACIT-TS-G items and one AHPEQS item demonstrated ceiling effect. Instruments overall demonstrated poor discrimination, however, all-cause PIVC failure was significantly associated with several individual items in the instruments (e.g., AHPEQS, 'unexpected physical and emotional harm'). EQ5D-5L demonstrated trivial (ES < 0.20) responsiveness.

CONCLUSIONS

Initial investigation of an existing health-related quality of life measure (EQ5D-5L) and two patient-reported experience measures (FACIT-TS-G; AHPEQS) suggest they are inadequate (as a summary measure) to assess outcomes and experiences for patients with PIVCs. Reliable instruments are urgently needed to inform quality improvement and benchmark standards of care.

The effectiveness of dressings and securement devices to prevent central venous catheter-associated complications: A systematic review and meta-analysis

BACKGROUND

Central venous catheters are commonly used in healthcare, but they come with a range of potential complications. Over the last 15 years, an influx of securement and dressing products has been released, with unknown overall effectiveness to prevent these complications.

OBJECTIVE

To compare the effects of dressings and securement devices for central venous catheters on a range of common complications including catheter-related bloodstream infection, catheter tip colonisation, entry/exit-site infection, skin colonisation, skin irritation, failed catheter securement, dressing durability and mortality.

DESIGN

Systematic review with meta-analysis.

METHODS

Following standard Cochrane methods, a systematic search of Cochrane Wounds Trials Register, Cochrane Central Register of Controlled Trials, MEDLINE Ovid, Embase Ovid, EBSCO CINAHL, and multiple clinical trial registries was completed in November 2022. Randomised controlled trials evaluating the effectiveness of dressing and securement devices for all CVC types were included. A random-effects model was used during the meta-analysis. Results were expressed using risk ratio (RR), rate ratio, or mean difference (MD), with 95 % confidence intervals (CIs). Methodological quality and bias were assessed.

RESULTS

We included 46 studies involving 10,054 participants. All studies had either an unclear or high-performance bias. The blinding of outcome assessment was unclear in most studies. Chlorhexidine gluconate-impregnated dressings, compared with standard polyurethane dressings, may reduce the incidence (7 studies; N = 5816; RR 0.60, 95 % CI 0.44-0.83; low certainty evidence) and rate (4 studies; N = 4447; RR 0.51, 95 % CI 0.32-0.79; moderate certainty evidence) of catheter-related bloodstream infection and catheter tip colonisation (8 studies; N = 4788; RR 0.70, 95 % CI 0.52-0.95; very low certainty evidence). Medication-impregnated dressings may reduce the incidence of catheter-related bloodstream infection (6 studies; N = 5687; RR 0.60, 95 % CI 0.39-0.93; low certainty evidence) and catheter-tip colonisation (7 studies; N = 4769; RR 0.60, 95 % CI 0.47-0.76; low certainty evidence) relative to non-impregnated dressing types. Tissue adhesive may increase the risk of skin irritation or damage compared with integrated securement dressings (3 studies; N = 166; RR 1.88, 95 % CI 1.09-3.24; low certainty evidence) or sutureless securement devices (4 studies; N = 241; RR 1.64, 95 % CI 1.10-2.44; moderate certainty evidence). Tissue adhesive increased dressing durability compared with integrated securement dressings (MD 43.03 h, 95 % CI 4.88-81.18; moderate certainty evidence) and sutureless securement devices (MD 42.90 h, 4.64-81.16; moderate certainty evidence). Tissue adhesive increased failed catheter securement rate compared with suture (2 studies; N = 103; RR 9.33, 95 % CI 1.10-79.21; moderate certainty evidence).

CONCLUSIONS

The findings of the review provide insights and guidance for clinicians in selecting the appropriate dressings and securements for catheters. Findings should be interpreted with caution due to heterogeneity in catheters and patient types.

The impact of a structured assessment and decision tool (I-DECIDED®) on improving care of peripheral intravenous catheters: A multicenter, interrupted time-series study

BACKGROUND

Peripheral intravenous catheters are the most widely used invasive device in hospitals but have serious risks.

OBJECTIVE

To determine if a structured assessment and decision tool (I-DECIDED®) improves daily peripheral intravenous catheter assessment and care decisions.

DESIGN

Prospective, interrupted time-series study.

SETTINGS

Seven adult inpatient wards in three Australian hospitals.

PARTICIPANTS

825 adults with 867 peripheral intravenous catheters.

METHODS

Between August 2017 and December 2018, peripheral intravenous catheter assessments and chart audits were undertaken with informed patient consent. Following a 4-month pre-intervention period (with 2-weekly measures), the I-DECIDED® tool was implemented over 3 months (no data collection) using multiple strategies (stakeholder meetings, vascular access device form, education sessions, ward champions, lanyard cards, and posters), followed by a 4-month post-intervention period (with 2-weekly measures). Primary outcomes were device utilization (number of peripheral intravenous catheters per total number of patients screened); idle/unused catheters; insertion site complications, substandard dressing quality; and primary bloodstream infections.

RESULTS

Of 2055 patients screened, 1175 (57.2%) had a peripheral intravenous catheter, and 825 patients (867 catheters) consented and were included in the final analysis. Device utilization increased from 42.0% of catheters at baseline to 49.6% post-intervention (absolute risk difference [ARD] 7.5%, 95% confidence interval [CI] 4.8, 10.3; relative risk [RR] 1.18, 95% CI 1.11, 1.25; p < 0.001). The proportion of idle catheters reduced from 12.7% to 8.3% (ARD -4.4%, 95% CI -8.5, -0.3; RR 0.66, 95% CI 0.44, 0.97; p = 0.035). Peripheral intravenous catheter complications reduced from 16.1% to 10.9% (ARD -5.2%, 95% CI -9.7, -0.6; RR 0.68, 95% CI 0.48, 0.96; p = 0.026). Substandard dressings reduced from 24.6% to 19.5% (ARD -5.2%, 95% CI -10.7, 0.4; RR 0.79, 95% CI 0.61, 1.02; p = 0.067). Only one primary bloodstream infection occurred (post-intervention).

CONCLUSIONS

Implementation of a comprehensive device assessment and decision tool (I-DECIDED®) reduced idle catheters and catheter complications, despite higher device utilization. Dressing quality improved but was not statistically significant. Further implementation of the tool could improve hospital safety for patients with an intravenous catheter.

What blood conservation practices are effective at reducing blood sampling volumes and other clinical sequelae in intensive care? A systematic review

OBJECTIVES

The objective of this study was to critically appraise and synthesise evidence for blood conservation strategies in intensive care. Blood sampling is a critical aspect of intensive care to guide clinical decision-making. Repeated blood sampling can result in blood waste and contamination, leading to iatrogenic anaemia and systemic infection.

REVIEW METHOD USED

Cochrane systematic review methods were used including meta-analysis, and independent reviewers.

DATA SOURCES

A systematic search was conducted in Medline, CINAHL, PUBMED and EMBASE databases. The search was limited to randomised controlled trials (RCTs) and cluster RCTs, published in English between 2000 and 2021.

REVIEW METHODS

Paired authors independently assessed database search results and identified eligible studies. Trials comparing any blood conservation practice or product in intensive care were included. Primary outcomes were blood sample volumes and haemoglobin change. Secondary outcomes included proportion of patients receiving transfusions and infection outcomes. Quality appraisal employed the Cochrane Risk of Bias tool. Meta-analysis using random effects approach and narrative synthesis summarised findings.

RESULTS

Eight studies (n = 1027 patients), all RCTs were eligible. Six studies included adults, one studied paediatrics and one studied preterm infants. Seven studies evaluated a closed loop blood sampling system, and one studied a conservative phlebotomy protocol. Studies were of low to moderate quality. Meta-analysis was not possible for interventions targeting blood sample volumes or haemoglobin. Decreased blood sample volumes reported in four studies were attributable to a closed loop system or conservative phlebotomy. No study reported a significant change in haemoglobin. Meta-analysis demonstrated that use of a closed system (compared to open system) reduced the proportion of patients receiving transfusion [Risk Ratio (RR) 0.65, 95% CI 0.46-0.92; 287 patients] and reduced intraluminal fluid colonisation [RR 0.25, 95% CI 0.07-0.58; 500 patients].

CONCLUSIONS

Limited evidence demonstrates closed loop blood sampling systems reduced transfusion use and fluid colonisation. Simultaneous effectiveness-implementation evaluation of these systems and blood conservation strategies is urgently required.

A randomised trial of intracavitary electrocardiography versus surface landmark measurement for central venous access device placement

BACKGROUND

Malpositioned central venous access devices (CVADs) can lead to significant patient injury including central vein thrombosis and dysrhythmias. Intra-cavitary electrocardiography (IC ECG) has been recommended by peak professional bodies as an accurate alternative for bedside CVAD insertion, to reduce risk of malposition and allowing immediate use of the device. Our objective was to compare the effect of IC ECG on CVAD malposition compared to traditional institutional practice for CVAD placement.

METHODS

Randomised controlled trial of IC ECG CVAD insertion verses traditional CVAD insertion (surface landmark measurement with post insertion x ray). Patient recruitment was from December 2016 to July 2018. The setting was a 900-bed tertiary referral hospital based in South Western Sydney, Australia. Three hundred and forty-four adult patients requiring CVAD insertion for intravenous therapy, were enrolled and randomly allocated (1:1 ratio) to either IC-ECG (n = 172) or traditional (n = 172) CVAD insertion. Our primary outcome of interest was the rate of catheters not requiring repositioning after insertion (ready for use). Secondary outcomes were comparison of procedure time and cost.

RESULTS

Of the 172 patients allocated to the IC ECG method, 170 (99%) were ready for use immediately compared to 139 of the 172 (81%) in the traditional insertion group (difference, 95% confidence interval (CI): 18%, 11.9-24.1%). The total procedure time was mean 15 min (SD 8 min) for IC ECG and mean 36 min (SD 17 min) for traditional CVAD insertion (difference-19.9 min (95% CI-14.6 to -34.4). IC ECG guided CVAD insertion had a cost reduction of AUD $62.00 per procedure.

CONCLUSIONS

Using IC-ECG resulted in nearly no requirement for post-insertion repositioning of CVADs resulting in savings in time and cost and virtually eliminating the need for radiographic confirmation.

Comparing the use of midline catheters versus peripherally inserted central catheters for patients requiring peripherally compatible therapies: A pilot randomised controlled trial (the compact trial)

BACKGROUND

Midline catheter (MC) use has increased in acute-care settings, particularly for patients with difficult venous access or requiring peripherally compatible intravenous therapy for up-to 14 days. Our aim was to assess feasibility and generate clinical data comparing MCs with Peripherally Inserted Central Catheters (PICCs).

METHODS

A two-arm parallel group pilot randomised controlled trial (RCT), comparing MCs with PICCs, was conducted in a large tertiary hospital in Queensland between September 2020 and January 2021. The primary outcome was study feasibility, measured against rates of eligibility (>75%), consent (>90%), attrition (<5%); protocol adherence (>90%) and missing data (<5%). The primary clinical outcome was all-cause device failure.

RESULTS

In total, 25 patients were recruited. The median patient age was 59-62 years; most patients were overweight/obese, with ≥2 co-morbidities.

PRIMARY OUTCOMES

The eligibility and protocol adherence criteria were not met; of 159 screened patients, only 25 (16%) were eligible, and three patients did not receive their allocated intervention post-randomisation (88% adherence). All-cause failure occurred in two patients allocated to MC (20%) and one PICC (8.3%).

CONCLUSIONS

Our study found that a fully powered RCT testing MCs compared with PICCs is not currently feasible in our setting. We recommend a robust process evaluation before the introduction of MCs into clinical practice.

Comparison of Low-Level to High-Level Disinfection in Eliminating Microorganisms From Ultrasound Transducers Used on Skin: A Noninferiority Randomized Controlled Trial

INTRODUCTION

There is a lack of international consensus as to whether high- or low-level disinfection (HLD or LLD) is required for ultrasound (US) transducers used during percutaneous procedures. This study compared the effectiveness of LLD to HLD on US transducers contaminated with microorganisms from skin.

METHODS

Two identical linear US transducers repeatedly underwent either LLD or HLD during the study. Randomization determined which of these transducers was applied to left and right forearms of each participant. Swabs taken from transducers before and after reprocessing were plated then incubated for 4-5 days, after which colony forming units (CFU) were counted and identified. The primary hypothesis was the difference in the proportion of US transducers having no CFUs remaining after LLD and HLD would be less than or equal to the noninferiority margin of -5%.

RESULTS

Of the 654 recruited participants 73% (n = 478) had microbial growth from both transducers applied to their left and right forearms before reprocessing. These were included in the paired noninferiority statistical analysis where, after disinfection, all CFUs were eliminated in 100% (95% CI: 99.4-100.0%) of HLD transducer samples (n = 478) and 99.0% (95% CI: 97.6-99.7%) of LLD transducer samples (n = 473). The paired difference in the proportion of transducers having all CFUs eliminated between LLD and HLD was -1.0% (95% CI: -2.4 to -0.2%, P-value <.001).

CONCLUSIONS

Disinfection with LLD is noninferior to HLD when microorganisms from skin have contaminated the transducer. Therefore, using LLD for US transducers involved in percutaneous procedures would present no higher infection risk compared with HLD.

Controlling peripheral intravenous catheter failure by needleless connector design: A pilot randomised controlled trial

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.

Midline Compared With Peripheral Intravenous Catheters for Therapy of 4 Days or Longer in Pediatric Patients: A Randomized Clinical Trial

Importance

Peripheral intravenous catheters (PIVCs) frequently fail during treatment causing therapy interruption, pain, recatheterization, and additional health care costs. Midline catheters (MCs) may improve functional dwell time and reduce failure compared with traditional PIVCs.

Objective

To compare device failure of MCs with PIVCs.

Design, Setting, and Participants

This was a pragmatic, randomized clinical superiority trial with an embedded internal pilot study conducted from July 2020 to May 2022. The study took place in a quaternary pediatric hospital in Brisbane, Queensland, Australia. Inclusion criteria were patients aged 1 to 18 years requiring peripherally compatible intravenous therapy for 4 days or longer.

Interventions

Patients were randomly assigned 1:1 to receive a PIVC or MC, stratified by age (≤5 years, >5 years). One catheter was studied per patient.

Main Outcomes and Measures

The primary outcome was all-cause device failure, defined as premature cessation of device function. Secondary outcomes included number of insertion attempts, insertion failure, pain (on insertion), procedural time, patient/parent satisfaction (with insertion), device dwell time, device complications during dwell time, additional vascular access devices required to complete treatment, clinician satisfaction (at removal), and health care costs.

Results

Of the 128 patients randomly assigned to study groups, 127 patients (median [IQR] age, 7 [2-13] years; 71 male [56%]) had a device inserted, with 65 (51.2%) in the PIVC group and 62 (48.8%) in the MC group. All patients were included in the intention-to-treat analysis. Device failure was lower in patients in the MC group (10 [16.1%]) compared with those in the PIVC group (30 [46.2%]; odds ratio [OR], 0.22; 95% CI, 0.10-0.52; P <.001). MCs were associated with fewer insertion attempts (mean difference [MD], -0.3; 95% CI, -0.5 to 0; P = .04), increased dwell time (MD, 66.9 hours; 95% CI, 36.2-97.5 hours; P <.001), and fewer patients required additional vascular access devices to complete treatment in the MC group (4 [6.5%]) and PIVC group (19 [29.2%]; OR, 0.17; 95% CI, 0.05-0.52; P = .002). Compared with PIVCs, use of MCs was associated with greater patient (9.0 vs 7.1 of 10; P = .002) and parent (9.1 vs 8.2 of 10; P = .02) satisfaction and lower health care costs (AUS -$151.67 [US -$101.13] per person; 95% credible interval, AUS -$171.45 to -$131.90 [US -$114.20 to -$87.95]).

Conclusions and Relevance

Findings suggest that MC insertion for patients requiring peripherally compatible intravenous therapy for 4 days or longer should be prioritized to reduce the resource intensive, expensive, and burdensome sequelae of device failure.

Factors impacting emergency department clinicians' peripheral intravenous catheter practice: A qualitative analysis

BACKGROUND

Peripheral intravenous catheters (PIVCs) are commonly used devices in emergency departments (EDs), and yet relatively little is known about factors influencing Australian clinicians' adherence to the national PIVC quality and safety Standard.

AIMS

To explore attitudes and experiences of ED clinicians around PIVC insertion and care processes.

METHODS

This study used an exploratory qualitative approach to analyse written responses to open-ended questions included in an online national (mixed data) survey. Snowballing methods were used to gather responses. Deductive analysis was used to analyse open-ended questions regarding practice and Standard adherence.

RESULTS

There were 340 written responses, mainly from nurses in public EDs, who reported suboptimal practices regarding idle catheters, lack of patient participation in care, antecubital fossa insertion, multiple insertion attempts, inadequate site preparation, poor documentation and insufficient review of PIVC. The main factors inhibiting ED clinicians from adhering to the Standard includes inadequate knowledge, perceptions of infeasibility, disbelief in evidence, ambiguous responsibilities, habitual practice, insufficient training, lack of recognition of good practice and inadequate engagement.

CONCLUSION

The factors that impact ED clinicians' PIVC Standard adherence are complex and multifactorial. Strategies and interventions are needed to facilitate the implementation of the Standard into daily practice and achieve sustainable behaviour change.

Exploring Australian emergency department clinicians' knowledge, attitudes and adherence to the national peripheral intravenous catheter clinical care standard: A cross-sectional national survey

OBJECTIVE

This study aimed to (i) capture clinicians' knowledge, attitude and adherence to the first Australian national peripheral intravenous catheter (PIVC) Clinical Care Standard, (ii) examine the instrument performance of the knowledge related questions and (iii) explore the educational needs for, and barriers to, Standard adherence among Australian ED clinicians.

METHODS

A cross-sectional national online survey was conducted from March to June 2022, using a snowball sampling method. The survey used 5-point Likert scales and multiple-choice questions to capture respondents' knowledge, attitude and adherence to the Standard as well as the educational needs for, and barriers to, Standard adherence.

RESULTS

In total, 433 ED nurses and doctors responded. Although nearly half (n = 206, 47.6%; 95% confidence interval [CI] 55.5-65.8) of respondents claimed that they were unfamiliar with the Standard, questions on PIVC knowledge yielded that most respondents had adequate knowledge of most of the key standards. Respondents' attitudes towards multiple intravenous insertion attempts and ongoing PIVC competency monitoring are not in agreement with the Standard. Self-reported practices regarding routine insertion of idle catheters (55%; 95% CI 49.9-59.9), using antecubital fossa as the first insertion site (84%; 95% CI 80-87), insertion without confidence (46%; 95% CI 41.2-51.1) and lack of routine reviewing the ongoing needs of PIVC (40%; 95% CI 35.3-45.1) were not aligned with the Standard. Unawareness of the Standard and non-practical recommendations were rated as the top barriers to Standard adherence.

CONCLUSION

The findings of the survey suggest that the Standard may need modification to align with the needs of ED clinicians. Future studies need to explore the applicability and relevancy of some recommendations in the ED settings as they may cause low adherence to the Standard.

A scoping review of nurse-led randomised controlled trials

BACKGROUND

Nurses comprise the largest portion of the healthcare workforce worldwide. However, nurse representation in the leadership of clinical research and research funding is largely unknown. The Australasian Nursing and Midwifery Clinical Trials Network was established to provide a coordinated network, focussed on building research capacity in nursing and midwifery. To support this work, this scoping review of nurse-led randomised controlled trials was conducted to summarise research activity, as well as highlight future research directions, gaps and resources. Midwife-led trials will be reported elsewhere.

AIM

To quantify number, type and quality of nurse-led randomised controlled trials registered between 2000-2021.

DESIGN

A scoping review of RCTs.

DATA SOURCES

Medline, Emcare and Scopus were searched from 2000 to August 2021. ANZCTR, NHMRC, MRFF and HRC (NZ) registries were searched from inception to July 2021.

REVIEW METHODS

This review was informed by the JBI scoping review framework using the PRISMA-ScR.

RESULTS

Our search yielded 188 nurse-led publications and 279 registered randomised controlled trials. Multiple trials had the same nurse leaders. There were more registrations than publications. Publications were predominantly of high methodological quality; however, there was a reliance on active controls and blinding was low. Trial registrations indicate that universities and hospital/healthcare organisations were the major sources of funding, while publications indicate that Governments and the National Health and Medical Research Council were the main funding bodies.

CONCLUSION

A small number of high-quality, large-scale, nationally funded randomised controlled trials were identified, with a larger number of locally funded small trials. There was a disparity between the number of registered trials and those published. Additional infrastructure, funding and career frameworks are needed to enable nurses to design, conduct and publish clinical trials that inform the health system and improve health outcomes.

RELEVANCE TO CLINICAL PRACTICE

Research initiated and led by nurses has the potential to improve the health and well-being of individuals and communities, and current nurse-led research is of high methodological quality; however, there were very few nurse-led RCTs, conducted by a small pool of nurse researchers. This gap highlights the need for support in the design, conduct and publishing of nurse-led RCTs.

PATIENT OR PUBLIC CONTRIBUTION

This is a scoping review; therefore, patient or public contribution is not applicable.

Implementation frameworks, strategies and outcomes used in peripheral intravenous catheter studies: A systematic review

AIMS

The aim of this study was to critically evaluate implementation frameworks, strategies and/or outcomes used to optimise peripheral intravenous catheter (PIVC) care and/or promote guideline adherence.

BACKGROUND

Although a considerable volume of research has investigated the effectiveness of PIVC interventions and treatments to promote performance and prevent harm, how to best implement this evidence into dynamic clinical settings and populations is not well understood. Implementation science is central to translating evidence-based knowledge to the bedside; however, there is a gap in identifying the best implementation framework, strategies and/or outcomes to optimise PIVC care and/or guideline adherence.

DESIGN

A systematic review.

METHOD

The review was conducted using innovative automation tools. Five databases and clinical trial registries were searched on 14 October 2021. Qualitative and quantitative PIVC intervention studies reporting implementation strategies were included in the review. Data were extracted independently by experienced researchers in pairs. The Mixed Method Appraisal tool was used to assess the quality of individual studies. Narrative synthesis was used to present the findings. The systematic review was reported following the PRISMA checklist.

RESULTS

Of 2189 references identified, 27 studies were included in the review. Implementation frameworks were used in 30% (n = 8) of studies, with most used during the preparation (n = 7, 26%) and delivery phase (n = 7, 26%) and then evaluation phase (n = 4, 15%). Multifaceted strategies were commonly adopted (n = 24, 89%) to promote PIVC care or study interventions which were clinician (n = 25, 93%) and patient-targeted (n = 15, 56%). The most commonly reported implementation outcomes were fidelity (n = 13, 48%) and adoption (n = 6, 22%). Most studies were scored as low quality (n = 18, 67%).

CONCLUSION

We call for researchers and clinicians to work together and use implementation science frameworks to guide study design, implementation and evaluation in future PIVC studies, to improve evidence translation and thereby improve patient outcomes.

Association between parenteral nutrition-containing intravenous lipid emulsion and bloodstream infections in patients with single-lumen central venous access: A secondary analysis of a randomized trial

BACKGROUND

Distinguishing primary bloodstream infections (BSIs) related to central venous access devices (CVADs) from those that occur through other mechanisms, such as a damaged mucosal barrier, is difficult.

METHODS

Secondary analysis was conducted on data from patients with CVADs that were collected for a large, randomized trial. Patients were divided into two groups: those who received parenteral nutrition (PN)-containing intravenous lipid emulsion (ILE) and those who did not have PN-containing ILE. This study investigated the influence of PN-containing ILE (ILE PN) on primary BSIs in patients with a CVAD.

RESULTS

Of the 807 patients, 180 (22%) received ILE PN. Most (627/807; 73%) were recruited from the hematology and hematopoietic stem cell transplant unit, followed by surgical (90/807; 11%), trauma and burns (61/807; 8%), medical (44/807; 5%), and oncology (23/807; 3%). When primary BSI was differentiated as a central line-associated BSI (CLABSI) or mucosal barrier injury laboratory-confirmed BSI (MBI-LCBI), the incidence of CLABSI was similar in the ILE PN and non-ILE PN groups (15/180 [8%] vs 57/627 [9%]; P = 0.88) and the incidence of MBI-LCBI was significantly different between groups (31/180 [17%] ILE PN vs 41/627 [7%] non-ILE PN; P < 0.01).

CONCLUSION

Our data indicate that twice as many primary BSIs in ILE PN patients are due to MBIs than CVADs. It is important to consider the MBI-LCBI classification, as some CLABSI prevention efforts aimed at CVADs for the ILE PN population may be better directed to gastrointestinal tract protection interventions.

Improving difficult peripheral intravenous access requires thought, training and technology (DART3): a stepped-wedge, cluster randomised controlled trial protocol

BACKGROUND

Peripheral intravenous catheters (PIVCs) are the most used invasive medical device in healthcare. Yet around half of insertion attempts are unsuccessful leading to delayed medical treatments and patient discomfort of harm. Ultrasound-guided PIVC (USGPIVC) insertion is an evidence-based intervention shown to improve insertion success especially in patients with Difficult IntraVenous Access (BMC Health Serv Res 22:220, 2022), however the implementation in some healthcare settings remains suboptimal. This study aims to co-design interventions that optimise ultrasound guided PIVC insertion in patients with DIVA, implement and evaluate these initiatives and develop scale up activities.

METHODS

A stepped-wedge cluster randomized controlled trial will be conducted in three hospitals (two adult, one paediatric) in Queensland, Australia. The intervention will be rolled out across 12 distinct clusters (four per hospital). Intervention development will be guided by Michie's Behavior Change Wheel with the aim to increase local staff capability, opportunity, and motivation for appropriate, sustainable adoption of USGPIVC insertion. Eligible clusters include all wards or departments where > 10 PIVCs/week are typically inserted. All clusters will commence in the control (baseline) phase, then, one cluster per hospital will step up every two months, as feasible, to the implementation phase, where the intervention will be rolled out. Implementation strategies are tailored for each hospital by local investigators and advisory groups, through context assessments, staff surveys, and stakeholder interviews and informed by extensive consumer interviews and consultation. Outcome measures align with the RE-AIM framework including clinical-effectiveness outcomes (e.g., first-time PIVC insertion success for DIVA patients [primary outcome], number of insertion attempts); implementation outcomes (e.g., intervention fidelity, readiness assessment) and cost effectiveness outcomes. The Consolidated Framework for Implementation Research framework will be used to report the intervention as it was implemented; how people participated in and responded to the intervention; contextual influences and how the theory underpinning the intervention was realised and delivered at each site. A sustainability assessment will be undertaken at three- and six-months post intervention.

DISCUSSION

Study findings will help define systematic solutions to implement DIVA identification and escalation tools aiming to address consumer dissatisfaction with current PIVC insertion practices. Such actionable knowledge is critical for implementation of scale-up activities.

How to improve the efficiency and the safety of real-time ultrasound-guided central venous catheterization in 2023: a narrative review

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.

Central venous access device practice across haematology and oncology centres in Australia and New Zealand: a cross-sectional survey

Central venous access devices (CVADs) are commonly used in malignancies. We conducted an online, anonymous cross-sectional survey of practice regarding CVAD management in haematology centres among clinicians in Australia and New Zealand. We identified variation in clinical practice regarding CVAD selection, insertion, management and removal. These findings highlight research gaps in CVAD care.

Integrated versus non-integrated peripheral intravenous catheters: a cross-sectional survey of nurse experiences

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.

Peripheral vascular catheter use in Latin America (the vascular study): A multinational cross-sectional study

Background

Peripheral intravenous catheter (PIVC) insertion is one of the most common clinical procedures worldwide, yet little data are available from Latin America. Our aim was to describe processes and practices regarding PIVC use in hospitalized patients related to hospital guidelines, characteristics of PIVC inserters, prevalence of PIVC complications, and idle PIVCs.

Methods

In 2019 we conducted a multinational, cross-sectional study of adult and pediatric patients with a PIVC in hospitals from five Latin American countries: Argentina, Brazil, Chile, Colombia, and Mexico. We used two data collection tools to collect hospital guidelines and patient-specific data on the day of the study. The vessel health and preservation (VHP) model guided synthesis of the study aims/questions and suggested opportunities for improvement.

Results

A total of 9,620 PIVCs in adult (86%) and pediatric inpatients in 132 hospitals were assessed. Routine replacement 8-72 hourly was recommended for adults in 22% of hospitals, rather than evidence-based clinical assessment-based durations, and 69% of hospitals allowed the use of non-sterile tape rather than the international standard of a sterile dressing. The majority (52%) of PIVCs were inserted by registered nurses (RNs), followed by nursing assistants/technicians (41%). Eight percent of PIVCs had pain, hyperemia, or edema, 6% had blood in the extension tubing/connector, and 3% had dried blood around the device. Most PIVCs had been inserted for intravenous medications (81%) or fluids (59%) in the previous 24 h, but 9% were redundant.

Conclusion

Given the variation in policies, processes and practices across countries and participating hospitals, clinical guidelines should be available in languages other than English to support clinician skills and knowledge to improve PIVC safety and quality. Existing and successful vascular access societies should be encouraged to expand their reach and encourage other countries to join in multinational communities of practice.

Integrated versus nonintegrated peripheral intravenous catheter in hospitalized adults (OPTIMUM): A randomized controlled trial

BACKGROUND

One-third of peripheral intravenous catheters (PIVCs) fail from inflammatory or infectious complications, causing substantial treatment interruption and replacement procedures.

OBJECTIVES

We aimed to compare complications between integrated PIVCs (inbuilt extension sets, wings, and flattened bases) and traditional nonintegrated PIVCs.

DESIGNS, SETTINGS AND PARTICIPANTS

A centrally randomized, controlled, superiority trial (with allocation concealment until study entry) was conducted in three Australian hospitals. Medical-surgical patients (one PIVC each) requiring intravenous therapy for >24 h were studied.

MAIN OUTCOME MEASURES

The primary outcome was device failure (composite: occlusion, infiltration, phlebitis, dislodgement, local, or bloodstream infection). Infection endpoints were assessor-masked. The secondary outcomes were: failure type, first-time insertion success, tip colonization, insertion pain, dwell time, mortality, costs, health-related quality of life, clinician, and patient satisfaction.

RESULTS

Out of 1759 patients randomized (integrated PIVC, n = 881; nonintegrated PIVC, n = 878), 1710 (97%) received a PIVC and were in the modified intention-to-treat analysis (2269 PIVC-days integrated; 2073 PIVC-days nonintegrated). Device failure incidence was 35% (145 per 1000 device-days) nonintegrated, and 33% (124 per 1000 device-days) integrated PIVCs.

INTERVENTION

Integrated PIVCs had a significantly lower failure risk (adjusted [sex, infection, setting, site, gauge] hazard ratio [HR]: 0.82 [95% confidence interval, CI: 0.69-0.96], p = .015). The per-protocol analysis was consistent (adjusted HR: 0.80 [95% CI: 0.68-0.95], p = .010). Integrated PIVCs had significantly longer dwell (top quartile ≥ 95 vs. ≥84 h). Mean per-patient costs were not statistically different.

CONCLUSIONS

PIVC failure is common and complex. Significant risk factors include sex, infection at baseline, care setting, insertion site, catheter gauge, and catheter type. Integrated PIVCs can significantly reduce the burden of PIVC failure on patients and the health system.

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.

Review article: Peripheral intravenous catheter insertion in adult patients with difficult intravenous access: A systematic review of assessment instruments, clinical practice guidelines and escalation pathways

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.

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.

Disinfection of needleless connectors to reduce Staphylococcus aureus bacterial load

HIGHLIGHTS

Compare effectiveness of chemical disinfectants in reducing S. aureus. Five disinfectants reduced the bacterial load, especially chlorhexidine solutions. Focus on Brazilian clinical practice of needleless connector disinfection.

PURPOSE

This study aimed to gain further knowledge about the comparative effectiveness of chemical disinfectants in reducing the bacterial load of NCs inoculated with S. aureus.

METHODS

Disinfection of needleless connectors was undertaken in vitro against S. aureus comparing 70% isopropyl alcohol (IPA), 70% ethanol, 0.5% and 2% chlorhexidine in 70% IPA applied with gauze, and 70% IPA single-use cap (Site-Scrub®).

RESULTS

All disinfectants reduced the bacterial load (P<0.001), especially the chlorhexidine solutions. Mechanical friction should follow guidelines.

CONCLUSION

This study found that all tested disinfectants effectively reduced the bacterial load and more clinical studies must be developed with a focus on the Brazilian clinical practice of needleless connector disinfection.

Awareness of Peripheral Intravenous Catheters Among Nurses, Physicians, and Students

OBJECTIVES

Peripheral intravenous catheters (PIVCs) are frequently used to meet patients' short-term health care needs. However, many PIVCs are not promptly removed at the completion of treatment, placing patients at risk of avoidable harm from serious complications including local and systemic infection. This study aims to report the proportion and accuracy of health care staff/students awareness of the presence of their patient's PIVC.

METHODS

We asked staff/students to recall the presence or absence of a PIVC in a patient under their care, as well as details of the date of insertion and PIVC location. We recorded concordance of responses with direct observations. To achieve this, face-to-face interviews were conducted with clinical staff/students at 2 adult hospitals.

RESULTS

Overall, 90% (n = 216) of staff responses (94% of nurses, 100% of nursing students, 76% of medical staff) correctly identified the presence/absence of a PIVC. Clinicians correctly identified the PIVC location 55% (n = 71) of the time.

CONCLUSIONS

Health care services must recognize the implications of this lack of awareness and implement and evaluate tailored quality improvement efforts to address this.

Quality measurement and surveillance platforms in critically ill children: A scoping review

BACKGROUND/AIM

The objective of this study was to describe current surveillance platforms which support routine quality measurement in paediatric critical care.

METHOD

Scoping review. The search strategy consisted of a traditional database and grey literature search as well as expert consultation. Surveillance platforms were eligible for inclusion if they collected measures of quality in critically ill children.

RESULTS

The search strategy identified 21 surveillance platforms, collecting 57 unique outcome (70%), process (23%), and structural (7%) quality measures. Hospital-associated infections were the most commonly collected outcome measure across all platforms (n = 11; 52%). In general, case definitions were not harmonised across platforms, with the exception of nationally mandated hospital-associated infections (e.g., central line-associated blood stream infection). Data collection relied on manual coding. Platforms typically did not provide an evidence-based rationale for measures collected, with no identifiable reports of co-designed, consensus-derived measures or consumer involvement in measure selection or prioritisation.

CONCLUSIONS

Quality measurement in critically ill children lacks uniformity in definition which limits local and international benchmarking. Current surveillance activities for critically ill children focus heavily on outcome measurement, with process, structural, and patient-reported measures largely overlooked. Long-term outcome measures were not routinely collected. Harmonisation of paediatric intensive care unit quality measures is needed and can be achieved using prioritisation and consensus/co-design methods.

Mapping progress in intravascular catheter quality surveillance: An Australian case study of electronic medical record data linkage

Background and significance

Intravascular (IV) catheters are the most invasive medical device in healthcare. Localized priority-setting related to IV catheter quality surveillance is a key objective of recent healthcare reform in Australia. We sought to determine the plausibility of using electronic health record (EHR) data for catheter surveillance by mapping currently available data across state-wide platforms. This work has identified barriers and facilitators to a state-wide EHR surveillance initiative.

Materials and methods

Data variables were generated and mapped from routinely used EHR sources across Queensland, Australia through a systematic search of gray literature and expert consultation with clinical information specialists. EHR systems were eligible for inclusion if they collected data related to IV catheter insertion, care, or outcomes of hospitalized patients. Generated variables were mapped against international recommendations for IV catheter surveillance, with data linkage and data export capacity narratively summarized.

Results

We identified five EHR systems, namely, iEMR, MetaVision ICU®, Multiprac, RiskMan, and the Nephrology Registry. Systems were used across jurisdictions and hospital wards. Data linkage was not evident across systems. Extraction processes for catheter data were not standardized, lacking clear and reliable extraction techniques. In combination, EHR systems collected 43/50 international variables recommended for catheter surveillance, however, individual systems collected a median of 24/50 (IQR 22, 30) variables. We did not identify integrated clinical analytic systems (incorporating machine learning) to support clinical decision making or for risk stratification (e.g., catheter-related infection).

Conclusion

Current data linkage across EHR systems limits the development of an IV catheter quality surveillance system to provide timely data related to catheter complications and harm. To facilitate reliable and timely surveillance of catheter outcomes using clinical informatics, substantial work is needed to overcome existing barriers and transform health surveillance.

Evaluating methods for the use and decontamination of needleless connectors: A qualitative inquiry

BACKGROUND

Needleless connectors (NCs) are essential devices designed to provide safe, needle-free connection between venous access devices, syringes and infusions. There is a variety of designs, and associated decontamination products and practices; the resulting confusion can cause detrimental patient outcomes. This study aimed to explore nurses' attitudes, techniques, and practices around the use and decontamination of NCs in clinical practice.

METHODS

Qualitative inquiry was conducted with seven focus groups of 4-6 participants each in the cancer and surgical units of a large tertiary hospital in Australia between January and March 2019. Participants comprised nurses who had taken part in a recent clinical trial of NC decontamination. Focus group sessions were recorded, transcribed and synthesised using content analysis.

RESULTS

Seven focus groups were conducted (total, N = 30 participants), lasting 16-20 min. Six major themes were identified surrounding needleless connector use and decontamination: 'safety and utility'; 'terminology and technological understanding'; 'clinical practice determinants'; 'decontamination procedures and influencers'; 'education and culture'; and 'research and innovation'.

CONCLUSION

The participants articulated positive attitudes towards needleless connector use for needle-stick and infection prevention, however rationales for care and maintenance practices demonstrated limited understanding of guidelines (e.g., disinfection time) and specific NC function (e.g., positive, negative pressure). The findings indicated the need for targeted, standardised needleless connector education, to enhance staff confidence, improve consistency of care and ensure patient safety.

Comparison of ultrasound-guided peripheral intravenous catheter insertion with landmark technique in paediatric patients: A systematic review and meta-analysis

BACKGROUND

Paediatric peripheral intravenous catheter (PIVC) insertion using traditional landmark insertion technique can be difficult.

AIM

To systematically review the evidence comparing landmark to ultrasound guidance for PIVC insertion in general paediatric patients.

STUDY DESIGN

Cochrane methodology to systematically search for randomised controlled trials comparing landmark to ultrasound-guided PIVC insertion.

DATA SOURCES

Cochrane Central Register of Controlled Trials, US National Library of Medicine, Cumulative Index to Nursing and Allied Health, Embase.

DATA EXTRACTION

English-language, paediatric trials published after 2000, reporting first-attempt insertion success, overall PIVC insertion success, and/or time to insert were included. Central venous, non-venous and trials including only difficult intravenous access were excluded. Data were independently extracted and critiqued for quality using GRADE by three authors, and analysed using random effects, with results expressed as risk ratios (RR), mean differences (MD) and 95% confidence intervals (CI). Registration (CRD42020175314).

RESULTS

Of 70 titles identified, 5 studies (995 patients; 949 PIVCs) were included. There was no evidence of an effect of ultrasound guidance, compared to landmark, for first-attempt insertion success (RR 1.27; 95% CI 0.90-1.78; I²  = 88%; moderate quality evidence), overall insertion success (RR 1.14; 95% CI 0.90-1.44; I²  = 82%; low quality evidence), or time to insertion (mean difference -3.03 min; 95% CI -12.73 to 6.67; I²  = 92%; low quality evidence).

LIMITATIONS

Small sample sizes, inconsistent outcomes and definitions in primary studies precluded definitive conclusions.

CONCLUSIONS

Large clinical trials are needed to explore the effectiveness of ultrasound guidance for PIVC insertion in paediatrics. Specifically, children with difficult intravenous access might benefit most from this technology.

Securing jugular central venous access devices with dressings fixed to a liquid adhesive in an intensive care unit population: a randomised controlled trial

BACKGROUND

Central venous access devices (CVADs) can have high rates of failure due to dressing-related complications. CVADs placed in the internal jugular vein are at particular risk of dressing failure-related complications, including catheter-associated bloodstream infection and medical adhesive-related skin injury. Application of Mastisol liquid adhesive (MLA) may reduce CVAD dressing failure and associated complications, by reducing the frequency of dressing changes. The aim of this study is to investigate whether, in an intensive care unit (ICU) population, standard dressing care with or without the addition of MLA, improves internal jugular CVAD dressing adherence.

METHODS

This two-arm, parallel group randomised controlled trial will be conducted in three Australian ICUs. A total of 160 patients (80 per group) will be enrolled in accordance with study inclusion and exclusion criteria. Patients will be randomised to receive either (1) 'standard' (in accordance with local hospital policy) CVAD dressings (control) or (2) 'standard' dressings in addition to MLA (intervention). Patients will be followed from the time of CVAD insertion to 48 h after CVAD removal. The primary outcome is 'dressing failure' defined as requirement for initial CVAD dressing to be replaced prior to seven days (routine replacement).

DISCUSSION

This study will be the first randomised controlled trial to evaluate the clinical effectiveness of MLA in the adult intensive care unit population and will also provide crucial data for patient-important outcomes such as infection and skin injury.

Peripheral intravenous catheters in the care of oncology and haematology patients

Aim

To determine peripheral intravenous catheter (PIVC) characteristics, complications and risk factors among patients in cancer units.

Methods

A secondary analysis of a global, cross-sectional study (127 hospitals in 24 countries). Participants (≥18 years) admitted to cancer units were assessed once for PIVC characteristics and the presence of complications. Variables included patient demographics, device characteristics, treatment details, and device and/or site complications. PIVC characteristics were presented using qualitative descriptors; mixed-effects logistic regression models determined risk factors for PIVC complications.

Results

In total, 1,807 participants (1,812 PIVCs) were included; 12% (n=215) of PIVCs presented with complications. Risk factors included: insertion by doctors; insertion in ED and ambulance/other locations; poor PIVC dressing integrity; dwell time ≥49 hours; and administration of colloids/blood products and antiemetics.

Conclusions

At least one in ten PIVCs in cancer units present with complications; regular PIVC assessment and improved dressing integrity is likely to reduce risk and improve outcomes.

Risk factors for peripheral intravascular catheter-related phlebitis in critically ill patients: analysis of 3429 catheters from 23 Japanese intensive care units

Background

Phlebitis is an important complication occurring in patients with peripheral intravascular catheters (PIVCs). The risk factors for phlebitis in the intensive care unit (ICU) was examined.

Methods

A secondary analysis of a prospective multicenter cohort study was conducted, involving 23 ICUs in Japan—the AMOR–VENUS study. Consecutive patients aged ≥ 18 years admitted to the ICU with newly inserted PIVCs after ICU admission were enrolled. Characteristics of the ICU, patients, PIVCs, and the drugs administered via PIVCs were recorded. A marginal Cox regression model was used to identify the risk factors associated with phlebitis.

Results

A total of 2741 consecutive patients from 23 ICUs were reviewed for eligibility, resulting in 1359 patients and 3429 PIVCs being included in the analysis population. The median dwell time was 46.2 h (95% confidence interval [CI], 21.3–82.9). Phlebitis occurred in 9.1% (95% CI, 8.2–10.1%) of catheters (3.5 cases/100 catheter days). The multivariate analysis revealed that the only factors that increased the risk of developing phlebitis were drugs administered intravenously. This study included 26 drugs, and 4 were associated with increased phlebitis: nicardipine (HR, 1.85; 95% CI, 1.29–2.66), noradrenaline (HR, 2.42; 95% CI, 1.40–4.20), amiodarone (HR, 3.67; 95% CI, 1.75–7.71) and levetiracetam (HR, 5.65; 95% CI, 2.80–11.4). Alternatively, factors significantly associated with a reduced risk of phlebitis were: standardized drug administration measures in the ICU (HR, 0.35; 95% CI, 0.17–0.76), 30≤ BMI (HR, 0.43; 95% CI, 0.20–0.95), catheter inserted by a doctor as nurse reference (HR, 0.55; 95% CI, 0.32–0.94), and upper arm insertion site as forearm reference (HR, 0.52; 95% CI, 0.32–0.85). The nitroglycerin was associated with a reduced phlebitis risk (HR, 0.22; 95% CI, 0.05–0.92).

Conclusion

Various factors are involved in the development of phlebitis caused by PIVCs in critically ill patients, including institutional, patient, catheter, and drug-induced factors, indicating the need for appropriate device selection or models of care in the ICU.

The burden of peripheral intravenous catheters in older hospital inpatients: A national cross-sectional study part of the ONE MILLION GLOBAL PERIPHERAL INTRAVENOUS CATHETERS COLLABORATION

OBJECTIVES

To investigate the burden of peripheral intravenous catheters (PIVCs) in older hospitalised patients.

METHODS

A cross-sectional prospective observational study (2014/2015) to describe the characteristics, indications and outcomes of PIVCs among patients aged ≥65 from 65 Australian hospitals.

RESULTS

Amongst 2179 individual PIVCs (in 2041 patients, mean age 77.6 years, 45% female, 58% in NSW), 43% were inserted by doctors and 74% used that day, meaning 25% were 'idle'. Overall, 18% (393/2179) exhibited signs of PIVC-related complications. Most commonly exhibited PIVC-related complications were tenderness (4.1%) and local redness (1.8%). Nearly one in three (29.1%) dressings was soiled, loosened or had come off, and only 36.8% had the time and date documented on the dressing. Both infusing IV medications (aOR 1.74, 95% CI 1.28-2.38, p < 0.001) and inserting the PIVC in a non-upper limb vein (aOR 3.40 compared to forearm [reference site], 95% CI 1.62-7.17, p < 0.001) were independently associated with PIVC failure. Phlebitis was exhibited in 7% (154) of the patients. Only infusing intravenous medications increased the likelihood of developing symptoms of phlebitis (aOR 1.61, 95% CI 1.01-2.57, p = 0.05). Increasing age was inversely associated with symptoms of phlebitis. Among the 1575 patients (79%) who rated their PIVC experience using the Likert scale 0-10 (where 10 = 'best possible'), the median score was 8 (IQR 6-10). Age in highest quartile (>84 years) was independently associated with lower likelihood of a high score (aOR 0.71, 95% CI 0.54-0.94, p = 0.02).

CONCLUSIONS

Given 1 in 5 PIVCs were identified with having complications, further research should focus on optimising PIVC use in older patients.

Intravenous antimicrobial administration through peripheral venous catheters - establishing risk profiles from an analysis of 5252 devices

INTRODUCTION

Peripheral venous catheters (PVCs) are used to administer antimicrobials, but many fail prior to completion of therapy. While some antimicrobials are known to increase the PVC failure rate, risk profiles for many are unclear.

OBJECTIVE

To synthesize data from prospective PVC studies conducted between 2013 and 2019 to determine associations between common antimicrobials and PVC failure.

METHODS

A secondary analysis was undertaken of seven randomized controlled trials and two prospective cohort studies from three quaternary hospitals (two adult and one paediatric) in Australia between 2013 and 2019. The primary outcome was PVC failure due to vessel injury (occlusion, infiltration or extravasation) or irritation (pain or phlebitis). Associations between antimicrobial use and PVC failure were explored using multi-variable Cox regression.

RESULTS

In total, 5252 PVCs (4478 patients) were analysed; vessel injury and irritations occurred in 19% and 11% of all PVCs, respectively. Vessel injury was significantly associated with cefepime hydrochloride [hazard ratio (HR) 2.50; 95% confidence interval (CI) 1.44-4.34], ceftazidime pentahydrate (HR 1.91, 95% CI 1.11-3.31), flucloxacillin sodium (HR 1.84, 95% CI 1.45-2.33), lincomycin hydrochloride (HR 1.67, 95% CI 1.10-2.52) and vancomycin hydrochloride (HR 1.73, 95% CI 1.25-2.40). Irritation was significantly associated with flucloxacillin sodium (HR 2.58, 95% CI 1.96-3.40).

CONCLUSIONS

This study identified several antimicrobials associated with increased PVC failure, including some that were already known to be associated and some that had not been identified previously. Research is needed urgently to determine superior modes of delivery (e.g. dilution, infusion time, device type) that may prevent PVC failure.

Peripheral intravenous cannulation decision-making in emergency settings: a qualitative descriptive study

OBJECTIVES

Rates of unused ('idle') peripheral intravenous catheters (PIVCs) are high but can vary per setting. Understanding factors that influence the decision-making of doctors, nurses and paramedics in the emergency setting regarding PIVC insertion, and what factors may modify their decision is essential to identify opportunities to reduce unnecessary cannulations and improve patient-centred outcomes. This study aimed to understand factors associated with clinicians' decision-making on whether to insert or use a PIVC in the emergency care setting.

DESIGN

A qualitative descriptive study using in-depth semistructured interviews and thematic analysis.

SETTING

Gold Coast, Queensland, Australia, in a large tertiary level emergency department (ED) and local government ambulance service.

PARTICIPANTS

Participants recruited were ED clinicians (doctors, nurses) and paramedics who regularly insert PIVCs.

RESULTS

From the 15 clinicians interviewed 4 key themes: knowledge and experience, complicated and multifactorial, convenience, anticipated patient clinical course, and several subthemes emerged relating to clinician decision-making across all disciplines. The first two themes focused on decision-making to gather data and evidence, such as knowledge and experience, and decisions being complicated and multifactorial. The remaining two themes related to the actions clinicians took such as convenience and anticipated patient clinical course.

CONCLUSION

The decision to insert a PIVC is more complicated than clinicians, administrators and policy-makers may realise. When explored, clinician decisions were multifaceted with many factors influencing the decision to insert a PIVC. In actual practice, clinicians routinely insert PIVCs in most patients as a learnt reflex with little cognitive input. When considering PIVC insertion, more time needs to be devoted to the awareness of: (1) decision-making in the context of the clinician's own experience, (2) cognitive biases and (3) patient-centred factors. Such awareness will support an appropriate risk assessment which will benefit the patient, clinician and healthcare system.

Improving peripheral venous cannula insertion in children: a mixed methods study to develop the DIVA key

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.

Peripheral intravenous catheter securement: An integrative review of contemporary literature around medical adhesive tapes and supplementary securement products

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.
