Reducing Procedural Pain and Avoiding Peripheral Intravenous Catheters by Implementing a Feeding Protocol for Late Preterm Infants: A Quality Improvement Project.

BACKGROUND: Late preterm births account for a large portion of preterm births, yet the optimal method of nutrition and enteral feeding in this population remains unclear and often involves intravenous (IV) fluids. PURPOSE: To develop and implement a late preterm feeding protocol in order to decrease the necessity of IV access, decrease the use of starter parenteral nutrition (PN), and reduce the pain endured by an infant in the neonatal intensive care unit. METHODS: The Plan-Do-Study-Act quality improvement model was utilized as a framework for the implementation of this quality improvement project. A literature review was conducted and subsequently, a feeding protocol was developed and included the more judicious use of starter PN. This protocol was implemented, evaluated, and adopted. A second Plan-Do-Study-Act cycle was completed with the addition of an auto-text reminder incorporated into admission notes in the electronic medical record. RESULTS: The implementation of the protocol significantly reduced placement of IV access and the use of starter (PN) in late preterm infants without considerable differences in balancing measures. The percentage of infants who received peripheral IV access declined considerably from 70% to 42% ( P = .0017) subsequently, less pain endured by the infants. There was a decrease in the initiation of starter PN from 55% to 7% ( P < .00001). IMPLICATIONS FOR PRACTICE: Administering enteral feedings on admission to stable, late preterm infants reduced the need for peripheral IV access and thus decreased pain from this procedure.

Aligning peripheral intravenous catheter quality with nursing culture-A mixed method study.

AIM: To explore barriers and facilitators that influence adherence to evidence-based guidelines for peripheral intravenous catheter care in different hospital wards. DESIGN: Sequential explanatory mixedmethod study design, with qualitative data used to elaborate on quantitative findings. METHOD: Data were collected between March 2021 and March 2022 using the previously validated Peripheral Intravenous Catheter mini questionnaire (PIVC-miniQ) on each ward in a tertiary hospital in Norway. Survey completion was followed by individual interviews with nurses from selected wards. The Pillar Integration Process was used to integrate and analyse the quantitative and qualitative findings. RESULTS: The PIVC-miniQ screening assessed 566 peripheral intravenous catheters in 448 patients in 41 wards, and we found variation between wards in the quality of care. Based on the quantitative variation, we interviewed 24 nurses on wards with either excellent or not as good quality. The integration of the quantitative and qualitative findings in the study enabled an understanding of factors that influence nurses' adherence to the care of peripheral venous catheters. One main theme and four subthemes emerged. The main finding was that ward culture affects education practice, and this was evident from four subthemes: (1) Deviation from best practice, (2) Gaps in education and clinical training, (3) Quality variation between wards and (4) The importance of supportive leadership. CONCLUSION: This mixed method study is the first study to explore reasons for variability in peripheral intravenous catheter quality across hospital wards. We found that ward culture was central to catheter quality, with evidence of deviations from best practice correlating with observed catheter complications. Ward culture also impacted nursing education, with the main responsibility for learning peripheral intravenous catheter management left to students' clinical training placements. Addressing this educational gap and fostering supportive leadership, including champions, will likely improve peripheral intravenous catheter care and patient safety. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Nurses learn good peripheral intravenous catheter care in wards with supportive leaders and champions. This implies that the quality of nursing practice and patient outcomes are situational. Nurses need a strengthened emphasis on peripheral catheter quality in the undergraduate curriculum, and nurse leaders must emphasize the quality of catheter care in their wards. IMPACT: The study findings impact nurse leaders who must commit to quality and safety outcomes by appointing and supporting local ward champions for promoting peripheral intravenous catheter care. This also impacts nursing education providers, as the emphasis on catheter care must be strengthened in the undergraduate nursing curriculum and continually reinforced in the hospital environment, particularly when guidelines are updated. REPORTING METHOD: The study adhered to the Good Reporting of A Mixed Method Study (GRAMM). PATIENT OR PUBLIC CONTRIBUTION: A patient representative has been involved in planning this study.

"Save the Vein" Initiative in Children With CKD: A Quality Improvement Study.

RATIONALE & OBJECTIVE: The preferred vascular access for hemodialysis recipients is an arteriovenous fistula in the nondominant arm. Prior placement of a peripheral intravenous (PIV) catheter can lead to vascular injury and limit options for arteriovenous fistula creation, a particular problem for children, who may need hemodialysis for their entire lifetime. We instituted an initiative to increase the frequency of PIV catheter placement in the dominant arm for hospitalized pediatric patients with advanced chronic kidney disease (CKD). STUDY DESIGN: Quality improvement initiative. SETTING & PARTICIPANTS: Children with CKD stage 3-5, receiving dialysis, and/or following kidney transplantation who were hospitalized at one children's hospital between September 2018 and August 2020. QUALITY IMPROVEMENT ACTIVITIES: Retrospective data on PIV catheter location for patients from January 1 to June 30, 2017, served as baseline data. Quality improvement activities consisted of: 1) education of the multidisciplinary treatment team, patients, and parents regarding importance of vein preservation; 2) placement of individualized notes in the electronic medical record identifying the preferred arm for PIV catheter placement; 3) use of "restricted extremity" arm bands; and 4) vascular access team participation to minimize attempts for PIV catheter placement. OUTCOME: Monthly compliance with placement of PIV catheters in dominant arms. ANALYTICAL APPROACH: Location of PIV catheter placements were determined monthly and used to create run charts describing compliance. RESULTS: At baseline and before institution of this initiative, 34 of 72 (47%) PIV catheters were placed in patients' dominant arms, with only 2 of 8 (25%) PIV catheters placed in the dominant arm for children aged<5 years. After instituting the initiative, 345 of 371 (93%) PIV catheters were placed in the dominant arm of 93 children; in children aged<5 years, 58 of 62 (94%) PIV catheters were placed in the dominant arm. Only 38 of 371 (10%) PIV catheters were placed in the antecubital vein. LIMITATIONS: Single-center study. CONCLUSIONS: Education regarding the importance of vein preservation, along with implementation of a standardized process for identifying children for whom vein preservation is important, can help direct PIV catheter placement and potentially preserve vasculature in pediatric patients with CKD.

Smart Glasses for Radial Arterial Catheterization in Pediatric Patients: A Randomized Clinical Trial.

BACKGROUND: Hand-eye coordination and ergonomics are important for the success of delicate ultrasound-guided medical procedures. These can be improved using smart glasses (head-mounted display) by decreasing the head movement on the ultrasound screen. The hypothesis was that the smart glasses could improve the success rate of ultrasound-guided pediatric radial arterial catheterization. METHODS: This prospective, single-blinded, randomized controlled, single-center study enrolled pediatric patients (n = 116, age less than 2 yr) requiring radial artery cannulation during general anesthesia. The participants were randomized into the ultrasound screen group (control) or the smart glasses group. After inducing general anesthesia, ultrasound-guided radial artery catheterization was performed. The primary outcome was the first-attempt success rate. The secondary outcomes included the first-attempt procedure time, the overall complication rate, and operators' ergonomic satisfaction (5-point scale). RESULTS: In total, 116 children were included in the analysis. The smart glasses group had a higher first-attempt success rate than the control group (87.9% [51/58] vs. 72.4% [42/58]; P = 0.036; odds ratio, 2.78; 95% CI, 1.04 to 7.4; absolute risk reduction, -15.5%; 95% CI, -29.8 to -12.8%). The smart glasses group had a shorter first-attempt procedure time (median, 33 s; interquartile range, 23 to 47 s; range, 10 to 141 s) than the control group (median, 43 s; interquartile range, 31 to 67 s; range, 17 to 248 s; P = 0.007). The overall complication rate was lower in the smart glasses group than in the control group (5.2% [3/58] vs. 29.3% [17/58]; P = 0.001; odds ratio, 0.132; 95% CI, 0.036 to 0.48; absolute risk reduction, 24.1%; 95% CI, 11.1 to 37.2%). The proportion of positive ergonomic satisfaction (4 = good or 5 = best) was higher in the smart glasses group than in the control group (65.5% [38/58] vs. 20.7% [12/58]; P <0.001; odds ratio, 7.3; 95% CI, 3.16 to 16.8; absolute risk reduction, -44.8%; 95% CI, -60.9% to -28.8%). CONCLUSIONS: Smart glasses-assisted ultrasound-guided radial artery catheterization improved the first-attempt success rate and ergonomic satisfaction while reducing the first-attempt procedure time and overall complication rates in small pediatric patients.

Appropriateness of Replacing Fluoroscopic Guidance With ECG-Electromagnetic Guidance for PICC Insertion: A Randomized Controlled Trial.

OBJECTIVE. Coupled ECG-electromagnetic (EM) guidance shows promise for use in placement of peripherally inserted central catheters (PICCs) when compared with the classic blind technique. However, ECG-EM guidance has not been appropriately compared with the reference standard of fluoroscopy (FX) guidance. Here, we aimed to compare ECG-EM guidance with FX guidance with regard to the final tip position of PICCs. SUBJECTS AND METHODS. A total of 120 patients (age range, 19-94 years) referred for PICC placement were randomized to the ECG-EM or FX group. All interventions were performed by PICC team members who had the same standardized training and experience. Final tip position was assessed using chest radiography and was classified as optimal, suboptimal, or inadequate requiring repositioning on the basis of the distance from the PICC tip to the cavoatrial junction (CAJ). Statistical analyses were performed using the Mann-Whitney U test for final catheter tip position (mean distance from CAJ) and Fisher and chi-square tests for proportions. RESULTS. PICCs were successfully inserted in 118 patients (53 men and 65 women). Catheter tip positions were optimal or suboptimal in 100% of the FX group and 77.2% of the ECG-EM group. Furthermore, precision of placement was significantly better (p = .004) in the FX group (mean distance from the PICC tip to the CAJ = 0.83 cm) than in the ECGEM group (mean distance from the PICC tip to the CAJ = 1.37 cm). Thirteen (22.8%) of the PICCs placed using ECG-EM guidance, all of which were inserted from the left side, were qualified as inadequate requiring repositioning and required another intervention. CONCLUSION. Our results revealed significant differences in final tip position between the ECG-EM and FX guidance techniques and indicate that ECG-EM guidance cannot appropriately replace FX guidance among unselected patients. However, ECGEM guidance could be considered as an acceptable technique for patients in whom the PICC could be inserted from the right side. TRIAL REGISTRATION. ClinicalTrials.gov NCT03652727.

Effect of wrist dorsiflexion on ultrasound-guided radial artery catheterisation using dynamic needle tip positioning technique in adult patients: a randomised controlled clinical trial.

BACKGROUND: It is generally recommended to keep the wrist joint mildly dorsiflexed during radial artery catheterisation. However, wrist dorsiflexion might decrease the success rate of radial artery catheterisation with dynamic needle tip positioning technique. Therefore, we assessed the success rates of two groups with or without wrist dorsiflexion by 5 cm wrist elevation in adult patients. METHODS: This randomised controlled clinical trial was performed between March and December 2018 in the First Affiliated Hospital of Shantou University Medical College, China. We recruited 120 adult patients undergoing major surgical procedures and randomly allocated them into two groups: dorsiflexion group (group D) and neutral group (group N). The primary outcome was first-attempt success rates of two groups. Secondary outcomes were overall success rates within 5 min; numbers of insertion and cannulation attempts; overall catheterisation time; duration of localisation, insertion and cannulation; and complication rates of catheterisation. RESULTS: First-attempt success rate was 88.3% in group D and 81.7% in group N (p=0.444). The overall success rate within 5 min was 93.3% in group D compared with 90.0% in group N (p=0.743). Numbers of insertion and cannulation attempts, overall catheterisation time, duration of localisation and insertion, and complication rates did not show a significant difference between the two groups. Cannulation time was longer in group N (35.68 s) than that in group D (26.19 s; p<0.05). CONCLUSION: Wrist dorsiflexion may not be a necessity for ultrasound-guided radial artery catheterisation using dynamic needle tip positioning technique in adult patients.

SCAI expert consensus statement update on best practices for transradial angiography and intervention.

Transradial angiography and intervention continues to become increasingly common as an access site for coronary procedures. Since the first "Best Practices" paper in 2013, ongoing trials have shed further light onto the safest and most efficient methods to perform these procedures. Specifically, this document comments on the use of ultrasound to facilitate radial access, the role of ulnar artery access, the utility of non-invasive testing of collateral flow, strategies to prevent radial artery occlusion, radial access for primary PCI and topics that require further study.

Chlorhexidine-impregnated sponge versus chlorhexidine gel dressing for short-term intravascular catheters: which one is better?

BACKGROUND: Chlorhexidine-gluconate (CHG) impregnated dressings may prevent catheter-related bloodstream infections (CRBSI). Chlorhexidine-impregnated sponge dressings (sponge-dress) and gel dressings (gel-dress) have never been directly compared. We used the data collected for two randomized-controlled trials to perform a comparison between sponge-dress and gel-dress. METHODS: Adult critically ill patients who required short-term central venous or arterial catheter insertion were recruited. Our main analysis included only patients with CHG-impregnated dressings. The effect of gel-dress (versus sponge-dress) on major catheter-related infections (MCRI) and CRBSI was estimated using multivariate marginal Cox models. The comparative risks of dressing disruption and contact dermatitis were evaluated using logistic mix models for clustered data. An explanatory analysis compared gel-dress with standard dressings using either CHG skin disinfection or povidone iodine skin disinfection. RESULTS: A total of 3483 patients and 7941 catheters were observed in 16 intensive care units. Sponge-dress and gel-dress were utilized for 1953 and 2108 catheters, respectively. After adjustment for confounders, gel-dress showed similar risk for MCRI compared to sponge-dress (HR 0.80, 95% CI 0.28-2.31, p = 0.68) and CRBSI (HR 1.13, 95% CI 0.34-3.70, p = 0.85), less dressing disruptions (OR 0.72, 95% CI 0.60-0.86, p < 0.001), and more contact dermatitis (OR 3.60, 95% CI 2.51-5.15, p < 0.01). However, gel-dress increased the risk of contact dermatitis only if CHG was used for skin antisepsis (OR 1.94, 95% CI 1.38-2.71, p < 0.01). CONCLUSIONS: We described a similar infection risk for gel-dress and sponge-dress. Gel-dress showed fewer dressing disruptions. Concomitant use of CHG for skin disinfection and CHG-impregnated dressing may significantly increase contact dermatitis. TRIALS REGISTRATION: These studies were registered within ClinicalTrials.gov (numbers NCT01189682 and NCT00417235 ).

Evaluating the sustained effectiveness of a multimodal intervention aimed at influencing PIVC insertion practices in the emergency department.

INTRODUCTION: Multimodal interventions (MMI) are frequently used in various healthcare settings to encourage change in healthcare personnel practices and improve patient safety. In 2013, an MMI conducted in an Australian metropolitan ED used clinician champions, guidelines, education sessions and promotional materials to encourage a reduction in unused and inappropriate peripheral intravenous cannulas (PIVC). A 60-day postintervention demonstrated a successful reduction in the number of unused PIVCs without changes in appropriate insertions. We aimed to investigate if this MMI produced a sustained effect in reducing the frequency of unused PIVCs inserted in this ED. METHODS: A single-centre retrospective cohort study of adult patients presenting to the above ED in Victoria, Australia, was conducted in April 2018. A random sample of 380 patients with a PIVC inserted in ED was assessed to determine if the PIVC was used (termed 'Long-term follow-up'). The appropriateness of unused PIVCs was assessed. Our findings were compared with previously collected data in 2013 ('Pre-Intervention' and 'Immediately Post-Intervention') to determine a sustained reduction in the frequency of unused PIVC insertions was achieved. Long-term analysis of the MMI, including the overall frequency of PIVC insertions in ED before and after the MMI, was also collected. RESULTS: In our Long-term follow-up cohort, 101 of 373 (27.1%, 95% CI 22.6% to 31.9%) PIVCs were unused (seven cases excluded). This was significantly lower than the Pre-Intervention cohort (139/376, 37.0%, 95% CI 32.1% to 42.1%). While not significant, the frequency of unused PIVCs in the Post-Intervention cohort was lower in comparison (73/378, 19.3%, 95% CI 15.4% to 23.7%). No significant change in the appropriateness of unused PIVCs was observed between the Post-Intervention and Long-term follow-up. The overall proportion of patients receiving a PIVC has remained low since the MMI. CONCLUSION: An MMI aimed at reducing unused PIVC insertions in ED has been effective in eliciting sustained change. Unused but appropriately inserted PIVCs seem unaffected by the intervention.

Use of peripheral vascular access in the prehospital setting: is there room for improvement?

BACKGROUND: Previous studies have shown that prehospital insertion of peripheral vascular access is highly variable. The aim of this study is to establish the proportion of peripheral vascular access placement and its use with regard to both the severity of cases and the main problem suspected by the paramedics involved. Over-triage was considered to have taken place where peripheral vascular access was placed but unused and these cases were specifically analysed in order to evaluate the possibility of improving current practice. METHODS: This is a one-year (2017) retrospective study conducted throughout one State of Switzerland. Data were extracted from the state's public health service database, collected electronically by paramedics on RescueNet® from Siemens. The following data were collected and analyzed: sex, age, main diagnosis suspected by paramedics and the National Advisory Committee for Aeronautics score (NACA) to classify the severity of cases. RESULTS: A total of 33,055 missions were included, 29,309 (88.7%) with a low severity. A peripheral vascular access was placed in 8603 (26.0%) cases. Among those, 3948 (45.9%) were unused and 2626 (66.5%) of these patients had a low severity score. Opiates represent 48.3% of all medications given. The most frequent diagnosis among unused peripheral vascular access were: respiratory distress (12.7%), neurological deficit without coma or trauma (9.6%), cardiac condition with thoracic pain and without trauma or loss of consciousness (9.6%) and decreased general condition of the patient (8.5%). CONCLUSIONS: Peripheral vascular access was set in 26% of patients, nearly half of which were unused. To reduce over-triage, special attention should be dedicated to cases defined by EMS on site as low severity, as they do not require placement of a peripheral vascular access as a precautionary measure. Alternative routes, such as the intra-nasal route, should be promoted, particularly for analgesia, whose efficiency is well documented. Emergency medical services medical directors may also consider modifying protocols of acute clinical situations when data show that mandatory peripheral vascular access, in stroke cases for example, is almost never used.

Implementing Clinical Practice Guidelines for Replacing Peripheral Intravenous Catheters.

BACKGROUND: A community hospital policy of routinely replacing peripheral intravenous catheters (PIVCs) needed updating to the clinical practice guideline (CPG) of clinically indicated replacement. METHODS: Guided by Lean principles, a clinical nurse leader (CNL) led a quality improvement small test of change on a 38-bed medical unit. The impact of the CPG was evaluated using quality, safety, and workflow measures. RESULTS: Nurses managed 469 inpatients, receiving 1033 PIVCs. Routine PIVC replacement declined from 34% to 3% (P < .001). PIVC dwell time ranged from 4 to 20 days and did not increase phlebitis (P = .41) or catheter-related bloodstream infections. Nurses attributed the improvements in workflow (P = .01) and the quality of patient care (94%) to the updated PIVC guideline. CONCLUSIONS: Clinically-indicated PIVC replacement reduced unnecessary catheter insertions, maintained patient safety, improved efficiency, and is being implemented hospital-wide. This project highlights and advances the CNL role in transforming healthcare.

A Randomized Trial Comparing Outcomes of 3 Types of Peripheral Intravenous Catheters.

BACKGROUND: There was an increase in peripheral intravenous catheter (PIVC) complications and adverse patient events after product conversion during the merger between a rural hospital and a larger hospital system. A review of the existing literature identified a gap in evidence evaluating 2 closed PIVC systems compared with an open PIVC system. PURPOSE: The purpose of the current project was to ascertain whether open or closed PIVCs are best for patients, staff, and the health care system in terms of 3 main criteria: quality, safety, and cost. METHODS: A prospective, 2-site randomized controlled trial was used to compare outcomes. RESULTS: There were no differences in the complication rates between catheter types. There was a statistically significant increase in blood leakage and a decrease in clinician satisfaction with the open-system catheter. CONCLUSIONS: Our project supports current clinical recommendation that a closed PIVC system, regardless of type, is not only safer and cost-effective but also preferred by patients and clinicians.

Smile - Secure my intravenous line effectively: A pilot randomised controlled trial of peripheral intravenous catheter securement in paediatrics.

AIM: Evaluate the feasibility of an efficacy randomised control trial (RCT) of paediatric peripheral intravenous catheter (PIVC) securement to prevent failure without resultant skin damage. METHODS: A 3-arm, pilot RCT in an Australian paediatric hospital. Random assignment of 330 children to receive (i) bordered polyurethane dressing (BPU) + non-sterile foam (NSF), (ii) integrated securement dressing (ISD) + sterile foam (SF), or (iii) tissue adhesive (TA)+ NSF. Primary outcomes were feasibility and PIVC failure. Secondary outcomes included: skin/bloodstream infection; occlusion; infiltration; dislodgement; phlebitis; dwell; serious adverse events; acceptability and microbial colonisation of catheter tips, wound site, and foam. RESULTS: Most feasibility outcomes were confirmed; 98% of eligible patients consented, 96% received their allocated dressing and no patients were lost to follow up. Eligilbility feasibility (58%) was not met. 11 randomised patients did not require a PIVC. Of 319 patients receiving a PIVC (20,716 PIVC-hours), a significant reduction in PIVC failure was demonstrated with ISD, 31/107 (29%, p = 0.017) compared to BPU, 47/105 (45%). Although not statistically significant, compared to BPU, TA 34/107 (32%, p = 0.052) was associated with less PIVC failure. On Cox regression, no securement intervention significantly reduced PIVC failure. Older age (HR 0.92; 95% confidence interval [CI] 0.88-0.96; p = <0.01), no infection at baseline (HR 0.51; 95% CI 0.34-0.78) and insertion by vascular access specialist (HR 0.40; 95% CI 0.26-0.64) were significantly associated with reduced failure (p < 0.05). CONCLUSION: ISD and TA had reduced PIVC failure compared to BPU. A large efficacy trial to test statistical differences is feasible and needed.

Development, Diagnostic Sensitivity, and Prognostic Accuracy of the Adult-Difficult Venous Catheterization Scale for Emergency Departments.

INTRODUCTION: Difficulty in accessing peripheral veins in emergency departments increases patients' discomfort and impedes their diagnosis. The objective of this study was to develop and test the prognostic accuracy of an easily applied scale to measure difficult venous access to peripheral veins in emergency departments, called the Adult-Difficult Venous Catheterization scale. METHODS: This prospective observational study was conducted in adults from the hospital catchment area attending the emergency department. Using the Delphi technique, 5 experts reached a consensus regarding a 3-item scale scored from 0 to 5. Concurrent validity and predictive validity were analyzed using a numeric rating scale and the number of access attempts, respectively. Internal consistency and interobserver reliability for 3 independent observers were analyzed using Cronbach alpha and Cohen kappa, respectively. RESULTS: In 392 participants, the concurrent and predictive validity scores pointed to positive relationships with the numeric rating scale (r = 0.82; P < 0.001) and the number of access attempts (r = 0.5; P < 0.001), respectively. The odds ratio for 1 to 2 access attempts versus more than 2 access attempts in relation to the Adult-Difficult Venous Catheterization scale score was 2.76 (95% confidence interval 1.86, 4.08; P < 0.001). Sensitivity and specificity values for the Adult-Difficult Venous Catheterization scale were good, at 93.75% and 78.99%, respectively, as were internal consistency (Cronbach alpha 0.81) and interobserver reliability (Cohen kappa 0.75). DISCUSSION: The Adult-Difficult Venous Catheterization scale is a valid and reliable instrument for predicting difficult venous access in emergency departments.

Acoustic Shadowing Facilitates Ultrasound-guided Radial Artery Cannulation in Young Children.

BACKGROUND: Arterial cannulation in young children can be challenging. Ultrasound guidance using focused acoustic shadowing may be suitable for guiding radial artery puncture in young children. The present research tested the hypothesis that ultrasound guidance using focused acoustic shadowing helps increase the success rate of radial artery cannulation in this population. METHODS: In a double-blinded, parallel-group trial, 79 young children undergoing surgery under general anesthesia were randomly assigned to two groups (1:1 ratio): the traditional ultrasound group and the novel ultrasound group. Young children in the traditional group underwent conventional ultrasound-guided radial artery puncture, whereas those in the novel ultrasound group underwent radial artery puncture guided by acoustic shadowing ultrasound with double developing lines. All radial artery punctures were performed using the short-axis out-of-plane approach. The primary endpoint was the success rate of cannulation at the first attempt. The secondary endpoints included cannulation failure rate, ultrasound location time, and puncture time. RESULTS: The success rate of cannulation at the first attempt in the novel ultrasound group (35 of 39 [90%]) was significantly higher than that in the traditional ultrasound group (24 of 40 [60%]; difference: 30% [95% CI, 12 to 48%], P =0.002). None of the patients in the ultrasound with acoustic shadowing group experienced failure of radial artery puncture and cannulation. The ultrasound location time and puncture time in the ultrasound acoustic shadowing group were significantly lower than that in the traditional ultrasound group (location time: median [interquartile range]: 6 [5, 8] vs. 18 [15, 21] s; puncture time: 24 [15, 41] vs. 40 [23, 56] s). CONCLUSIONS: Acoustic shadowing via the use of double developing lines significantly improved the success rate of radial artery puncture in young children, compared with that achieved with the use of traditional ultrasound guidance.

Adherence to Two Large-Bore Intravenous Lines in Acute Gastrointestinal Bleeding Is Low.

BACKGROUND: While the available literature recommends placement of two large-bore intravenous (2LBIV) lines in every patient presenting with acute GIB, the adherence and impact of this recommendation have never before been reported. AIMS: We designed a quality improvement project to assess whether the patients presenting to our institution with acute GIB have appropriate intravenous (IV) access or not. METHODS: We conducted a prospective, observational study, of all patients presenting to our emergency department with overt GIB over a 2-month period. Data analysis was performed, and based on the results, an intervention plan was developed and executed. Post-intervention data collection was done over a 3-month period. Our interventions included physician and nursing education, placing posters in the emergency department, and creation of an order set in the electronic medical record system. RESULTS: A total of 46 patients were in the pre-intervention group, and 71 patients were in the post-intervention group. The presence of 2LBIV lines in the pre-intervention group was only 19.5%, which improved to 36.6% in the post-intervention group (p = 0.049). Factors associated with placement of 2LBIV lines were being in the post-intervention group and admission to the intensive care unit. CONCLUSION: The relatively simple and cost-effective intervention of placing 2LBIV lines is not often executed. We suggest that specific mention of 2LBIV placement in guidelines from national gastroenterology societies might improve compliance in this aspect.

Implementation of a paediatric peripheral intravenous catheter care bundle: A quality improvement initiative.

AIM: To improve paediatric peripheral intravenous catheter (PIVC) care through the implementation of care bundles. METHODS: A pre-post study using mixed methods (clinical audit, staff survey, parent interviews) in 2016 at a tertiary paediatric hospital in Brisbane was conducted to evaluate the effectiveness of a PIVC insertion and maintenance bundle to improve PIVC insertion, promote function and support practice. Participants included children with PIVC, parents and staff inserting and managing PIVCs. A mnemonic care bundle, SUCCESS PIVCS (At insertion: Skills, Understand and prepare, Consent, Clean site, Escalate, Secure, Sign and document. During management: Prompt removal, Inspect hourly, Vein patency, Clean hands and Scrub the hub), was developed and implemented via visual aids, workshops and change champions. During audit, PIVC first-attempt insertion success, PIVC failure, PIVC dwell, escalation to senior clinicians and insertion and management procedures were measured. RESULTS: Pre-implementation audit (n = 102) and survey (n = 117) data described high rates of PIVC failure (n = 50; 49%), difficulty obtaining equipment (n = 64; 55%) and pressure to insert (n = 50; 43%). Parent interviews (n = 15) identified lack of communication, fear, appreciation of skilled technicians and technology and care giver roles as key to improving the experience. After implementation first-attempt insertion success (45 vs. 62%; risk ratio 1.37, 95% confidence interval 1.05-1.78), first-attempt escalation to senior clinicians (junior doctor 72 vs. 41%; P = <0.001) and median PIVC dwell (40 vs. 52 h; P = 0.021) improved. CONCLUSION: This multi-level care bundle demonstrated improvements in the insertion and management of PIVCs; however, PIVC failure remained high.

Optimal Position of Inferior Vena Cava Cannula in Pediatric Cardiac Surgery: A Prospective, Randomized, Controlled, Double-Blind Study.

OBJECTIVE: To examine the authors' hypothesis that during the cardiopulmonary bypass (CPB) in children, the inferior vena cava cannula tip placed proximal to the right hepatic vein orifice would produce a higher venous drainage compared with that placed distally. DESIGN: A prospective, randomized, controlled, double-blind study. SETTING: Single university hospital. PARTICIPANTS: Thirty-two patients aged <6years, scheduled for elective cardiac surgery using CPB for congenital heart disease. INTERVENTIONS: Participants were randomized to 2 groups: the proximal group with the cannula tip placed proximally within 1cm of the right hepatic vein orifice and the distal group with the cannula placed distally within 1cm of the right hepatic vein orifice. MEASUREMENTS AND MAIN RESULTS: The primary outcome of this study was the perfusion flow rate at the time of establishment of total CPB with cardioplegia. The authors initially planned to enroll 60 patients, but before reaching the target sample size, the authors terminated this study owing to patient safety, and 18 patients in the proximal group and 14 patients in the distal group finally were analyzed. No significant differences in patient characteristics were observed between the 2 groups. The mean perfusion flow rate in the proximal group was significantly greater (2.55 ± 0.27 L/min/m2) than that in the distal group (2.37 ± 0.20 L/min/m2, p = 0.04). CONCLUSION: The inferior vena cava cannula tip placed in the proximal position was clinically superior, compared with a distal placement, in producing higher perfusion flow in children.

Monitoring quality of care for peripheral intravenous catheters; feasibility and reliability of the peripheral intravenous catheters mini questionnaire (PIVC-miniQ).

BACKGROUND: Peripheral intravenous catheters (PIVCs) account for a mean of 38% of catheter associated bloodstream infections (CABSI) with Staphylococcus aureus, which are preventable if deficiencies in best practice are addressed. There exists no feasible and reliable quality surveillance tool assessing all important areas related to PIVC quality. Thus, we aimed to develop and test feasibility and reliability for an efficient quality assessment tool of overall PIVC quality. METHODS: The Peripheral Intravenous Catheter- mini Questionnaire, PIVC-miniQ, consists of 16 items calculated as a sum score of problems regarding the insertion site, condition of dressing and equipment, documentation, and indication for use. In addition, it contains background variables like PIVC site, size and insertion environment. Two hospitals tested the PIVC-miniQ for feasibility and inter-rater agreement. Each PIVC was assessed twice, 2-5 min apart by two independent raters. We calculated the intraclass correlation coefficient (ICC) for each hospital and overall. For each of the 16 items, we calculated negative agreement, positive agreement, absolute agreement, and Scott's pi. RESULTS: Sixty-three raters evaluated 205 PIVCs in 177 patients, each PIVC was assessed twice by independent raters, in total 410 PIVC observations. ICC between raters was 0.678 for hospital A, 0.577 for hospital B, and 0.604 for the pooled data. Mean time for the bedside assessment of each PIVC was 1.40 (SD 0.0007) minutes. The most frequent insertion site symptom was "pain and tenderness" (14.4%), whereas the most prevalent overall problem was lack of documentation of the PIVC (26.8%). Up to 50% of PIVCs were placed near joints (wrist or antecubital fossae) or were inserted under suboptimal conditions, i.e. emergency department or ambulance. CONCLUSIONS: Our study highlights the need for PIVC quality surveillance on ward and hospital level and reports the PIVC-miniQ to be a reliable and time efficient tool suitable for frequent point-prevalence audits.

Ultrasound-guided vs. palpation-guided techniques for radial arterial catheterisation in infants: A randomised controlled trial.

BACKGROUND: The usefulness of ultrasound-guided techniques for radial arterial catheterisation has been well identified; however, its usefulness has not been completely evaluated in infants under 12 months of age, who are generally considered the most difficult group for arterial catheterisation. OBJECTIVE: We evaluated whether ultrasound guidance would improve success rates and reduce the number of attempts at radial arterial catheterisation in infants. DESIGN: A randomised, controlled and patient-blinded study. SETTING: Single-centre trial, study period from June 2016 to February 2017. PATIENTS: Seventy-four infants undergoing elective cardiac surgery. INTERVENTION: Patients were allocated randomly into either ultrasound-guided group (group US) or palpation-guided group (group P) (each n=37) according to the technique applied for radial arterial catheterisation. All arterial catheterisations were performed by one of two experienced anaesthesiologists based on group assignment and were recorded on video. MAIN OUTCOME MEASURES: The primary endpoint was the first-pass success. The number of attempts and total duration of the procedure until successful catheterisation were also analysed. RESULTS: The first-pass success rate was significantly higher in the group US than in the group P (68 vs. 38%, P = 0.019). In addition, fewer attempts were needed for successful catheterisation in the group US than in the group P (median 1 [IQR 1 to 2] vs. 2 [1 to 4], P = 0.023). However, the median [IQR] procedural time (s) until successful catheterisation in the two groups was not significantly different (102 [49 to 394] vs. 218 [73 to 600], P = 0.054). CONCLUSION: The current study demonstrated that the ultrasound-guided technique for radial arterial catheterisation in infants effectively improved first-pass success rate and also reduced the number of attempts required.
