The efficacy of ultrasonography on learning curve and inter-subject performance variability in radial artery cannulation in standardized training for residents: a randomized controlled trial.

AIM: To evaluate the effect of ultrasound (US) on learning curve and inter-subject performance variability of residents in radial artery cannulation. MATERIAL AND METHODS: Twenty non-anesthesiology residents who received standardized training in an anesthesiology department were selected and divided into two groups: anatomy group or US group. After training of relevant anatomy, US recognition and puncture skill, residents selected 10 patients either under US or anatomical localization performing radial artery catheterization. The number and time of successful cases of catheterization were recorded, success rate of first attempt and catheterization, as well as the total success rate of catheterization were calculated. The learning curve and inter-subject performance variability of residents were also calculated. Complications and the residents' satisfaction for teaching and self-confidence before puncture were also recorded. RESULTS: Compared to the anatomy group, total success rate and the success rate at first attempt were higher in US-guided group (88% vs. 57%, 94% vs. 81%). The average performance time in the US group was significantly less (2.9±0.8 min vs. 4.2±2.1 min) and the mean number of attempts was 1.6, while 2.6 for the anatomy group. With performing cases increasing, the average puncture time of residents in the US group decreased by 19s, while 14s in the anatomy group. More local hematoma occurred in the anatomy group. The satisfaction and confidence degree of residents were higher in US group ([98.5±6.5] vs [68.5±7.3], [90.2±8.6] vs [56.3±5.5]). CONCLUSION: US can significantly shorten the learning curve, reduce the inter-subject performance variability, improve the first attempt and total success rate of radial artery catheterization for non-anesthesiology residents.

The implementation of a standardized optimal procedure for peripheral venous catheters' management: Results from a multi-dimensional assessment.

Peripheral Venous Catheter (PVC) is a widely used device in the hospital setting and is often associated with significant adverse events that may impair treatment administration and patient health. The aim of the present study is to define the incremental benefits related to the implementation and the standardized and simultaneous use of three disposable devices for skin antisepsis, infusion, and cleaning, assuming the hospital's point of view, from an effectiveness, efficiency, and organizational perspective. For the achievement of the above objective, real-life data were collected by means of an observational prospective study, involving two hospitals in the Liguria Region (Northern Italy). Consecutive cases were enrolled and placed into two different scenarios: 1) use of all the three disposable devices, thus representing the scenario related to the implementation of a standardized optimal procedure (Scenario 1); 2) use of only one or two disposable devices, representing the scenario related to not being in a standardized optimal procedure (Scenario 2). For the definition of effectiveness indicators, the reason for PVC removal and the PVC-related adverse events occurrence were collected for each patient enrolled. In addition, an activity-based costing analysis grounded on a process-mapping technique was conducted to define the overall economic absorption sustained by hospitals when taking in charge patients requiring a PVC. Among the 380 patients enrolled in the study, 18% were treated with the standardized optimal procedure (Scenario 1). The two Scenarios differed in terms of number of patients for whom the PCV was removed due to the end of therapy (86.8% versus 39.40%, p-value = 0.000), with a consequent decrease in the adverse events occurrence rate. The economic evaluation demonstrated the sustainability and feasibility of implementing the standardized optimal procedure specifically related to the need for lower economic resources for the hospital management of adverse events occurred (€19.60 versus €21.71, p-value = 0.0019). An organizational advantage also emerged concerning an overall lower time to execute all the PVC-related activities (4.39 versus 5.72 minutes, p-value = 0.00). Results demonstrate the feasibility in the adoption of the standardized optimal procedure for PVC management, with significant advantages not only from a clinical point of view, but also from an organizational and economic perspective, thus being able to increase the overall operational efficiency of the hospitals.

The curative effect analysis of peripherally inserted central venous catheter catheterization for tumor patients under the guidance of new medical guide wire.

OBJECTIVE: To report a method of PICC catheterization with the aid of a new medical guide wire, and to discuss the curative effect. METHODS: Five hundred and thirteen patients who visited our hospital from January 2013 to December 2019 for PICC catheterization were selected as study subjects. Random number method was used to group patients. General information was recorded for both groups. Patients in the observation group received catheterization with the aid of a new medical guide wire. The control group received catheterization via conventional guide wire. The success rate of the first catheterization, the success rate of the catheterization, the timing of the catheterization, the complications and the position of the catheter end were compared between the two groups. RESULTS: There was no significant difference in general information between the two groups. After analyzing the puncture situation of the two groups, it was found that the average catheterization time of the observation group was shorter than that of the control group, and the difference was statistically significant. Patients in the observation group had higher success rate of one-time catheterization and catheterization success rate, and the difference was statistically significant. The incidences of occult thrombosis, phlebitis and catheter blockage in the observation group were lower than those in the control group, and the difference was statistically significant. The incidence of dominant thrombosis and bleeding at puncture point in the observation group was also lower than that in the control group, but the difference was not statistically significant. CONCLUSION: The new type of medical guide wire component is effective for PICC catheterization and worthy of further promotion.

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.

Qualitative interviews and supporting evidence to identify the positive impacts of multidisciplinary vascular access teams.

BACKGROUND: Vascular access by means of intravenous catheters is essential for the safe, effective and cost-efficient delivery of intravenous fluids, antibiotics, nutrition and chemotherapy, but the use of these devices is not without complications. PURPOSE: A faculty of multidisciplinary European vascular access team (VAT) Leads/Members and experts sought to reframe how the implementation of a VAT could have positive impacts on patients and hospitals. METHODS: Interview data from a Faculty of nine VAT Leads/Members and experts from six European countries on the impact of multidisciplinary VATs in modern healthcare were assessed. A literature search was conducted that included Medline®-cited peer-reviewed articles published in the past 10 years in order to identify impact data and post-implementation of a multidisciplinary VAT that support the benefits to patient safety and satisfaction and to hospital efficiencies reported in the interview program. RESULTS: While VATs vary in structure and function, clarity of purpose and supportive training and education are key. Barriers to the implementation of VATs show commonality across countries, such as lack of investment, insufficient training and lack of awareness. Proven markers of VAT success include rapid referrals, improved patient outcomes and improved organizational efficiency. Standardization of outcomes data capture, processing and reporting are key to monitoring performance against baseline. Awareness of the cost of complications arising from inappropriate choice and placement, and poor care and maintenance, of the vascular access device must be raised. CONCLUSIONS: The implementation of VATs can positively impact patient safety and satisfaction, improve organizational efficiencies and cost-effectiveness, and could create new opportunities for in- and outpatient services, beneficial to both patients and institutions.

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.

Reducing the incidence of phlebitis in medical adult inpatients with peripheral venous catheter care bundle: a best practice implementation project.

BACKGROUND: One major complication of the insertion of a peripheral venous catheter (PVC) is phlebitis, often resulting in delay of treatment, increased healthcare costs and prolonged hospitalization. AIMS: The current study sought to evaluate the effectiveness of a standardized PVC care bundle in increasing the compliance of PVC care and assessment and reduce the occurrences of phlebitis rates. METHODS: A pre and postimplementation audit approach was used in this study and adopted the Joanna Briggs Institute Practical Application of Clinical Evidence System and Getting Research into Practice program. This study was carried out in three phases over a 10-month period, from March 2017 to December 2017 across three medical wards in a hospital in Singapore with a sample size of 90 patients. The study involved educating nurses on phlebitis assessment, implementing a PVC care bundle and monitoring compliance. An audit tool comprising four criteria from the Joanna Briggs Institute Practical Application of Clinical Evidence System was developed. RESULTS: One-month and 3-month postimplementation findings revealed significant improvement in Criteria 1, 3 and 4 (P < 0.001) but no significant improvement in Criterion 2 (P > 0.05). Six-month postimplementation findings showed significant improvement in all four criteria (P < 0.05). An interesting finding was that the number of reported occurrences of phlebitis increased after implementing the PVC care bundle. DISCUSSION: The increase in phlebitis rates could be attributed to the care bundle facilitating prompt and early identification of phlebitis. Despite the initial increase in occurrences 1 month post implementation, the general effectiveness of the care bundle in reducing occurrences of phlebitis was seen 6 months post implementation. The effectiveness of the care bundle to reduce phlebitis rates may be even more evident across a longer implementation period. CONCLUSION: The current study showed that the implementation of a standardized PVC care bundle can significantly enhance the assessment and identification process of phlebitis and can aid in reducing the incidence of phlebitis. The nurses' compliance in practicing the PVC care bundle was determined by the post and preimplementation audits, thus, the audit approach was beneficial in translating evidence into practice.

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. TRIAL REGISTRATION NUMBER: ChiCTR1800015262.

"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.

Standard Versus Long Peripheral Catheters for Multiday IV Therapy: A Randomized Controlled Trial.

OBJECTIVES: In children, intravenous therapy (IVT) is generally administered via peripheral intravenous catheters (PIVCs) (2-6 cm in length). There is evidence that PIVCs are unreliable after 2 days. Long peripheral catheters (LPCs) (6-15 cm in length) could improve the delivery of IVT. The aim of this trial was to determine if LPCs could decrease catheter failure and the number of catheters in children receiving multiday IVT. METHODS: This was an open-label randomized controlled trial conducted at Monash Children's Hospital in Melbourne, Australia. Participants were from the ages of 1 to 17 years, undergoing surgery and requiring >48 hours of postoperative IVT. Participants were randomly assigned to a 2.5-cm 22G PIVC or an 8-cm 22G LPC. RESULTS: Seventy-two children were randomly assigned, 36 received PIVCs, and 36 received LPCs. The median duration of IVT was 5.1 days and was similar between groups (P = .9). Catheter failure was higher for PIVCs than LPCs (66.7% vs 19.4%; relative risk [RR]: 3.4; P = .0001 or 187.9 vs 41.0 failures per 1000 catheter-days). Infiltration was the most common reason for PIVC failure (33.3% vs 2.8%; RR: 12.0; P = .001). LPCs exhibited superior life span (4.7 vs 3.5 days [median]; P = .01). Children with LPCs were twice as likely to complete therapy with a single catheter (80.6% vs 38.9%; RR: 2.1; P = .0006). CONCLUSIONS: LPCs reduce catheter failure and total catheters in children. They should be considered as the first-line device for peripheral access in any child receiving prolonged IVT.

Acceso venoso difícil en pediatría / Difficult venous access in pediatrics

BACKGROUND: Cannulation of a peripheral venous access is a routine procedure in pediatric patients admitted to the hospital. 50% of the time cannulation on the first attempt is not feasible, so it is necessary to repeat the puncture, resulting in a complex and frustrating procedure. Half of the children admitted to the hospital have a difficult venous access (DIVA). OBJECTIVE: To carry out a review, which provides information about DIVA in pediatrics, how to evaluate and proceed in these patients. DESIGN: DIVA Score considers vein palpability, vein visibility, age and history of prematurity. The score ranges from 0 to 10 points. Values greater than 4 are associated with difficult venous access. There are associated risk factors: obesity, musculoskeletal malformations, chemotherapy treatment, diabetes mellitus, patients on dialysis, limb edema, moderate to severe dehydration, history of difficult venous access, anxiety of the patient and/or parents report that the child is less likely to cooperate. When making the decision to establish a venous access, it should be evaluated whether it is an emergency or not, the characteristics of the medications and infusions, the time of therapy and the anatomical sites for puncture. Ultrasound and transillumination techniques decrease the time to obtain a venous access and increase the success rate on the first attempt. CONCLUSION: The decision to obtain a venous access must take into account the criteria and risk factors for DIVA. The most recognized scale is the DIVA Score.

INTRODUCCIÓN: La canulación de un acceso venoso periférico es un procedimiento rutinario en los pacientes pediátricos que ingresan al hospital. 50% de las veces la canulación al primer intento es frustra, por lo que es necesario repetir la punción resultando el procedimiento complejo y frustrante. La mitad de los niños que ingresa al hospital presentan un acceso venoso difícil (DIVA, sigla derivada de "difficult intravenous access"). OBJETIVO: Realizar una revisión, que entrega información acerca de DIVA en pediatría, cómo evaluar y proceder en estos pacientes. DESARROLLO: DIVA Score considera palpabilidad y visibilidad venosa, edad y antecedente de prematurez. El puntaje va desde 0 a 10 puntos. Valores mayores a 4 se asocian a acceso venoso difícil. Existen factores de riesgo asociados: obesidad, malformaciones osteomusculares, tratamiento con quimioterapia, diabetes mellitus, pacientes en diálisis, edema de extremidades, deshidratación moderada a severa, historia de acceso venoso difícil, ansiedad del paciente y/o padres que refieren que el niño es poco probable que coopere. Al tomar la decisión de establecer un acceso venoso se debe evaluar si es urgencia o no, las características de los medicamentos e infusiones, tiempo de terapia y los sitios anatómicos para punción. La ultrasonografía y las técnicas de transiluminación disminuyen el tiempo de obtención del acceso venoso e incrementan la tasa de éxito en el primer intento. CONCLUSIÓN: En la decisión de obtener un acceso venoso se deben tener en cuenta los criterios y factores de riesgo de acceso venoso difícil. La escala más reconocida es el DIVA Score.

Association of Infectious Disease Physician Approval of Peripherally Inserted Central Catheter With Appropriateness and Complications.

Importance: Peripherally inserted central catheters (PICCs) are frequently used to deliver intravenous antimicrobial therapy. However, inappropriate PICC use may lead to patient harm. Objective: To evaluate whether infectious disease physician approval prior to PICC placement for intravenous antimicrobials is associated with more appropriate device use and fewer complications. Design, Setting, and Participants: This cohort study of 21 653 PICCs placed for a primary indication of intravenous antimicrobial therapy between January 1, 2015, and July 26, 2019, was conducted in 42 hospitals participating in a quality collaborative across Michigan among hospitalized medical patients. Main Outcomes and Measures: Appropriateness of PICCs was defined according to the Michigan Appropriateness Guide for Intravenous Catheters as a composite measure of (1) single-lumen catheter use, (2) avoiding use of PICCs for 5 days or less, and (3) avoiding use of PICCs for patients with chronic kidney disease (defined as an estimated glomerular filtration rate <45 mL/min/1.73 m2). Complications related to PICCs included catheter occlusion, deep vein thrombosis, and central line-associated bloodstream infection. The association between infectious disease physician approval, device appropriateness, and catheter complications was assessed using multivariable models, adjusted for patient comorbidities and hospital clustering. Results were expressed as odds ratios with 95% CIs. Results: A total of 21 653 PICCs were placed for intravenous antimicrobials (11 960 PICCs were placed in men [55.2%]; median age, 64.5 years [interquartile range, 53.4-75.4 years]); 10 238 PICCs (47.3%) were approved by an infectious disease physician prior to placement. Compared with PICCs with no documented approval, PICCs with approval by an infectious disease physician were more likely to be appropriately used (72.7% [7446 of 10 238] appropriate with approval vs 45.4% [5180 of 11 415] appropriate without approval; odds ratio, 3.53; 95% CI, 3.29-3.79; P < .001). Furthermore, approval was associated with lower odds of a PICC-related complication (6.5% [665 of 10 238] with approval vs 11.3% [1292 of 11 415] without approval; odds ratio, 0.55; 95% CI, 0.50-0.61). Conclusions and Relevance: This cohort study suggests that, when PICCs were placed for intravenous antimicrobial therapy, infectious disease physician approval of PICC insertion was associated with more appropriate device use and fewer complications. Policies aimed at ensuring infectious disease physician approval prior to PICC placement for antimicrobials may improve patient safety.

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

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

Ultrasound-Guided Peripheral Intravenous Catheter Insertion: The Nurse's Manual.

Peripheral intravenous catheter placement is a skill that is used daily in the hospital. However, many nurses face the challenge of cannulating increasingly complex and difficult-to-access vasculature. Although emergency department clinicians have been using ultrasound to facilitate this procedure for the last 18 years, ultrasound-guided peripheral intravenous catheter placement has not been as rapidly adopted in the critical and acute care nursing realms. Given the benefits of this procedure, including increased patient satisfaction and reduced use of central catheters, its use should be encouraged among all acute care clinicians. The aim of this article is to provide the bedside nurse with a basic understanding of the techniques involved in placing ultrasound-guided peripheral intravenous catheters in patients with difficult venous access.

Hiding in Plain Sight: Peripheral Intravenous Catheter Infections.

TOPIC: This article presents an overview of the burden of peripheral intravenous catheter infections and current evidence-based recommendations for prevention. CLINICAL RELEVANCE: Peripheral intravenous catheters are ubiquitous in most health care settings, fostering an acceptance of the peripheral intravenous catheter as benign and inevitable. This device, however, is far from benign, with reported failure rates as high as 90% from complications such as infection and phlebitis. Although reported rates of bloodstream infection related to peripheral intravenous catheters are much lower than those attributed to central venous catheters, the exponentially higher use of peripheral intravenous catheters indicates that the absolute number of peripheral venous catheter-related bloodstream infections is likely as high as and may surpass the number of central venous catheter-related bloodstream infections, with significant associated morbidity and mortality. PURPOSE OF PAPER: Sustained improvements in outcomes related to peripheral intravenous catheters will depend on recognition of the root causes of failure and increased commitment to practice patterns consistent with infusion therapy standards of practice, effective education about peripheral intravenous catheters, accurate documentation of all aspects of peripheral intravenous catheter management, and consistent surveillance of patient outcomes related to peripheral intravenous catheters. CONTENT COVERED: This article reviews the significant burden of peripheral intravenous catheter infections, barriers to effective peripheral intravenous catheter management, and current evidence-based recommendations to prevent this source of patient harm.

Care of peripheral intravenous catheters in three hospitals in Spain: Mapping clinical outcomes and implementation of clinical practice guidelines.

BACKGROUND: Peripheral intravenous catheters (PIVCs) are the most widely used invasive devices worldwide. Up to 42% of PIVCs are prematurely removed during intravenous therapy due to failure. To date, there have been few systematic attempts in European hospitals to measure adherence to recommendations to mitigate PIVC failures. AIM: To analyse the clinical outcomes from clinical practice guideline recommendations for PIVC care on different hospital types and environments. METHODS: We conducted an observational study in three hospitals in Spain from December 2017 to April 2018. The adherence to recommendations was monitored via visual inspection in situ evaluations of all PIVCs inserted in adults admitted. Context and clinical characteristics were collected by an evaluation tool, analysing data descriptively. RESULTS: 646 PIVCs inserted in 624 patients were monitored, which only 52.7% knew about their PIVC. Regarding PIVC insertion, 3.4% (22/646) patients had at least 2 PIVCs simultaneously. The majority of PIVCs were 20G (319/646; 49.4%) and were secured with transparent polyurethane dressing (605/646; 93.7%). Most PIVCs (357/646; 55.3%) had a free insertion site during the visual inspection at first sight. We identified 342/646 (53%) transparent dressings in optimal conditions (clean, dry, and intact dressing). PIVC dressings in medical wards were much more likely to be in intact conditions than those in surgical wards (234/399, 58.7% vs. 108/247, 43.7%). We identified 55/646 (8.5%) PIVCs without infusion in the last 24 hours and 58/646 (9.0%) PIVCs without infusion for more than 24 hours. Regarding PIVC failure, 74 (11.5%) adverse events were identified, all of them reflecting clinical manifestation of phlebitis. CONCLUSIONS: Our findings indicate that the clinical outcome indicators from CPG for PIVC care were moderate, highlighting differences between hospital environments and types. Also, we observed that nearly 50% of patients did not know what a PIVC is.

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.

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

BACKGROUND: Adherence to the best standards of nursing practice is the fundamental principle to improve patient outcome and prevent nursing procedure related-infections. A peripheral venous catheter (PVC) is the most common invasive procedure performed in nursing care. Its poor performance could expose patients to bloodstream-related infections. The present study aimed to assess post-basic nursing students' knowledge of evidence-based guidelines on the management of peripheral venous catheters. METHODS: A cross-sectional study design was conducted on May 01-03, 2019, using a convenient sample 239 among post-basic nursing students in Wollega University. RESULTS: The study result showed that nursing students' had a low mean (4.1±1.52) of knowledge about PVC procedure management. Only 41% of the respondents have adhered to recommendations of CDC guidelines. Among the provided options of the items, none achieved 100% correct answers. The majority of nursing students (77%) responded that antiseptic handwashing is always performed before insertion of PVCs. Meanwhile, few students (5%) correctly answered that the infusion set is recommended to be removed after 96 hours when neither lipids nor blood products are administered. In multivariable regression analysis, nursing students who had received training (AOR = 2.9, 95% CI (1.6, 5.1)) and who were younger (AOR = 2.4, 95% CI (1.3, 4.3)) significantly associated with a higher score of knowledge. CONCLUSIONS: This study finding shows that an overall level of knowledge of post-basic nursing students is inadequate. Measurements such as an increase in the provision of adequate training by nurses educators based on evidence-based guidelines could improve the post-basic nursing students' knowledge.
