Intraoperative Blood Pressure Monitoring in Obese Patients.

BACKGROUND: The optimal method for blood pressure monitoring in obese surgical patients remains unknown. Arterial catheters can cause potential complications, and noninvasive oscillometry provides only intermittent values. Finger cuff methods allow continuous noninvasive monitoring. The authors tested the hypothesis that the agreement between finger cuff and intraarterial measurements is better than the agreement between oscillometric and intraarterial measurements. METHODS: This prospective study compared intraarterial (reference method), finger cuff, and oscillometric (upper arm, forearm, and lower leg) blood pressure measurements in 90 obese patients having bariatric surgery using Bland-Altman analysis, four-quadrant plot and concordance analysis (to assess the ability of monitoring methods to follow blood pressure changes), and error grid analysis (to describe the clinical relevance of measurement differences). RESULTS: The difference (mean ± SD) between finger cuff and intraarterial measurements was -1 mmHg (± 11 mmHg) for mean arterial pressure, -7 mmHg (± 14 mmHg) for systolic blood pressure, and 0 mmHg (± 11 mmHg) for diastolic blood pressure. Concordance between changes in finger cuff and intraarterial measurements was 88% (mean arterial pressure), 85% (systolic blood pressure), and 81% (diastolic blood pressure). In error grid analysis comparing finger cuff and intraarterial measurements, the proportions of measurements in risk zones A to E were 77.1%, 21.6%, 0.9%, 0.4%, and 0.0% for mean arterial pressure, respectively, and 89.5%, 9.8%, 0.2%, 0.4%, and 0.2%, respectively, for systolic blood pressure. For mean arterial pressure and diastolic blood pressure, absolute agreement and trending agreement between finger cuff and intraarterial measurements were better than between oscillometric (at each of the three measurement sites) and intraarterial measurements. Forearm performed better than upper arm and lower leg monitoring with regard to absolute agreement and trending agreement with intraarterial monitoring. CONCLUSIONS: The agreement between finger cuff and intraarterial measurements was better than the agreement between oscillometric and intraarterial measurements for mean arterial pressure and diastolic blood pressure in obese patients during surgery. Forearm oscillometry exhibits better measurement performance than upper arm or lower leg oscillometry.

Effects of the MAGIC Guidelines on PICC Placement Volume: Advanced Practice Provider and Physician Trends Among Medicare Beneficiaries From 2010 to 2018.

BACKGROUND. The Michigan Appropriateness Guide for Intravenous Catheters (MAGIC) was published in 2015, recommending more restricted indications for peripherally inserted central catheter (PICC) placement, particularly for those placed by physicians. Changes in PICC placement volume since the publication of MAGIC is largely unknown. OBJECTIVE. The purpose of this article was to study the trends in volume and reimbursement for PICC placement by physicians and advanced practice providers (APPs) for Medicare enrollees from 2010 to 2018 with specific attention to the changes in volume after the publication of MAGIC in 2015. METHODS. Claims from the Medicare Part B Physician/Supplier Procedure Summary Master File for the years 2010-2018 were extracted using the Current Procedural Terminology code for PICC placement. Total volume and payment amounts (for the professional component) were analyzed. Trendline slopes for volume per 100,000 Medicare beneficiaries before and after the 2015 publication of MAGIC were compared. RESULTS. Volume for PICC placement by physicians and APPs steadily declined from 243,837 in 2010 to 130,361 in 2018 (46.5%). The PICC placement volume decreased sharply after the 2015 publication of the MAGIC guidelines. The slope of the trendline for all providers from 2010 to 2015 was -3.4 compared with -7.3 from 2015 to 2018. The change in slope was more pronounced for radiologists (-3.1 to -5.6) than for APPs (0.0 to -1.1). Professional payment per procedure for radiologists decreased from $78.04 in 2010 to $70.17 in 2018, and reimbursement for APPs proportionally decreased from $65.76 to $60.66 during this time. The relative share of PICC placement by radiologists declined from 77.0% in 2010 to 70.6% in 2018, with a corresponding increase in relative share by APPs from 13.5% to 18.4%. The percentage placed in outpatient procedures increased from 15.1% to 18.2%. CONCLUSION. The volume of PICC placements has steadily decreased since 2010, with a sharper decline between 2015 and 2016 corresponding with the publication of the MAGIC evidence-based guidelines. The role of APPs in PICC placement has increased over this time period. CLINICAL IMPACT. The findings of this study suggest that evidence-based guidelines impact clinical practice on a national level.

Extended dwell and standard ultrasound guided peripheral intravenous catheters: Comparison of durability and reliability.

Background Vascular access is a critical component of emergency department (ED) care. Ultrasound guided placement of peripheral intravenous (USIV) catheters is increasingly common. However, USIV are thought to suffer from reduced durability and higher complication rates. Extended dwell catheters (EDC) are long peripheral IVs placed under combined ultrasound and wire guidance. The goal of this study is to compare dwell times and complication rates of EDC to standard peripheral USIV. Methods We performed a retrospective cohort study at a tertiary care adult ED comparing IV placements during a 17-month period (8/1/2018-12/31/2019), stratified by standard USIV versus EDC. The primary outcome was catheter dwell time and secondary outcomes included need for inpatient vascular access team (VAST) consultation, peripherally inserted central catheter (PICC) insertions, and radiocontrast extravasations. Multivariable Cox regression time-to-event analyses were used to evaluate dwell times, adjusting for age, gender, BMI and end-stage renal disease. Results 359 EDC and 4190 standard USIV were included for analysis. Most USIV (95.6%) and EDC (98.3%) were placed by ED technicians trained in ultrasound vascular access. EDC median dwell time (5.9 days [95%CI: 5.1-6.7]) exceeded standard USIV (3.8 days [95% CI: 3.6-4.0]). Patients with EDC placed in the ED required less VAST consultation (0.84 vs 0.99 charges/encounter), had similar rates of PICC line use (8.0% vs 8.4% of encounters) and had no radiocontrast extravasation events. Multivariable Cox regression demonstrated survival benefit (longer dwell time) favoring EDC (HR 0.70 [95%CI 0.60-0.81]). Conclusion Use of EDC results in longer dwell time and reduces subsequent use of vascular access resources, while maintaining low complication rates. EDC demonstrate superior durability which may justify their selection over standard USIV in some patients.

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.

An Ancillary Central Catheter Emergency Support Service Team Staffed by Surgical Personnel Improves Workflow During the Coronavirus Disease 2019 Crisis.

Background. The SARS-CoV-2 novel coronavirus disease 2019 (COVID-19) pandemic has posed significant challenges to urban health centers across the United States. Many hospitals are reallocating resources to best handle the influx of critical patients. Methods. At our New York City hospital, we developed the ancillary central catheter emergency support service (ACCESS), a team for dedicated central access staffed by surgical residents to assist in the care of critical COVID-19 patients. We conducted a retrospective review of all patients for whom the team was activated. Furthermore, we distributed a survey to the critical care department to assess their perceived time saved per patient. Results. The ACCESS team placed 104 invasive catheters over 10 days with a low complication rate of .96%. All critical care providers surveyed found the service useful and felt it saved at least 30 minutes of procedural time per patient, as patient to critical care provider ratios were increased from 12 patients to one provider to 44 patients to one provider. Conclusions. The ACCESS team has helped to effectively redistribute surgical staff, provide a learning experience for residents, and improve efficiency for the critical care team during this pandemic.

Administration of 3% Sodium Chloride Through Peripheral Intravenous Access: Development and Implementation of a Protocol for Clinical Practice.

BACKGROUND: Patients with traumatic brain injury, cerebral edema, and severe hyponatremia require rapid augmentation of serum sodium levels. Three percent sodium chloride is commonly used to normalize or augment serum sodium level, yet there are limited data available concerning the most appropriate route of administration. Traditionally, 3% sodium chloride is administered through a central venous catheter (CVC) due to the attributed theoretical risk of phlebitis and extravasation injuries when hyperosmolar solution is administered peripherally. CVCs are associated with numerous complications, including arterial puncture, pneumothorax, infection, thrombosis, and air embolus. Peripherally infused 3% sodium chloride may bypass these concerns. AIMS: To explore the evidence for peripherally infused 3% sodium chloride and to implement the findings. METHODS: The Iowa Model of Evidence-Based Practice (EBP) was used to guide the project. A multidisciplinary team was established, and they developed an evidence-based protocol for the administration of 3% sodium chloride using peripheral intravenous catheters (PIVs), identified potential barriers to implementation, and developed targeted education to implement this practice change in a large academic medical center. RESULTS: Of the 103 patients in this project, only three (2.9%) identified adverse events. Two were associated with continuous infusions, and one was associated with a bolus infusion. LINKING ACTION TO EVIDENCE: This is the first study to describe a multidisciplinary protocol development and implementation process for the administration of 3% sodium chloride peripherally. Utilizing a multidisciplinary team is critical to the success of an EBP project. Implementing an evidence-based PIV protocol with stringent monitoring criteria for the administration of 3% sodium chloride has the potential to reduce adverse events related to CVC injury.

The Rise of Transradial Artery Access for Percutaneous Coronary Intervention in Patients with Acute Coronary Syndromes in Australia.

OBJECTIVES: The aim of this study was to evaluate the outcomes of acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI) via transradial artery access (TRA) or transfemoral artery access (TFA). BACKGROUND: Over the last decade, evidence for the benefit of TRA for PCI has grown, leading to a steady uptake of TRA around the world. Despite this, the topic remains controversial with contrary evidence to suggest no significant benefit over TFA. METHODS: A retrospective study of consecutive ACS patients from 2011 to 2017 who underwent PCI via TRA or TFA. The primary outcome was Major Adverse Cardiovascular Events (MACE), a composite of death, myocardial infarction (MI), target lesion revascularisation (TLR), or coronary artery bypass graft surgery (CABG) at 12 months. Secondary outcomes included Bleeding Academic Research Consortium (BARC) bleeding events scored 2 or higher, haematoma formation, and stent thrombosis, in addition to all individual components of MACE. RESULTS: We treated 3624 patients (77% male), with PCI via TFA (n = 2391) or TRA (n = 1233). Transradial artery access was associated with a reduction in mortality (3% vs 6.3%; p < 0.0001), MI (1.8% vs 3.9%; p=0.0004), CABG (0.6% vs 1.5%; p=0.0205), TLR (1% vs 2.9%; p < 0.0001), large haematoma (0.4% vs 1.8%; p=0.0003), BARC 2 (0.2% vs 1.1%; p=0.0029), and BARC 3 events (0.4% vs 1.0%; p=0.0426). On multivariate Cox regression analysis, TFA, age ≥ 75, prior PCI, use of bare metal stents, cardiogenic shock, cardiac arrest, and multivessel coronary artery disease were associated with an increased risk of MACE. CONCLUSION: Despite the limitations secondary to the observational nature of our study and multiple confounders, our results are in line with results of major trials and, as such, we feel that our results support the use of TRA as the preferred access site in patients undergoing PCI for ACS to improve patient outcomes.

Peripherally inserted central venous catheter (PICC) in outpatient and inpatient oncological treatment.

PURPOSE: So far there is little evidence on peripherally inserted central venous catheter (PICC) in radiation oncology patients maintaining the access during the periods of ambulatory and hospital treatment. METHODS: A total of 522 PICC placements in 484 patients were performed between 11/2011 and 07/2016 at the Department of Radiation Oncology and analysed retrospectively for complications and treatment- and patient-related factors during ambulatory and hospital inpatient use. On initial hospitalization, all patients received a multimodal radio-oncological treatment consisting of radiation and intravenous therapy administered via the PICC. RESULTS: A total of 18,292 catheter days were documented. Median follow-up from catheter insertion to their removal was 37 days (1-97). The overall complication rate was 4.1 per 1000 catheter days (n = 75, 14.4%). Complications were similar between the cohort of outpatient 3.6 per 1000 catheter days and the cohort of inpatient 4.8 per 1000 catheter days (OR 0.976; 95% CI [0.598; 1.619]; p = 0.924). Severe bloodstream infections occurred at a rate of 0.60 per 1000 catheter days (n = 11, 2.1%), deep vein thrombosis at a rate of 0.82 per 1.000 catheter days (n = 15, 2.9%) and local inflammation at a rate of 1.26 per 1.000 catheter days (n = 23, 4.4%). Only immunotherapy could be identified as an independent risk factor for complications (OR 5.6; 95% CI [2.4; 13.1]; p < 0.001). CONCLUSION: Using PICC in outpatients is not associated with an elevated risk of complications. Particular attention should be payed to early identification of PICC associated bloodstream infections. Immunotherapy is an independent risk factor for local skin complication.

A prospective journey of the peripherally inserted central catheter service, at a tertiary paediatric centre in Western Australia.

BACKGROUND: To document the evolution of the Peripherally Inserted Central Catheter service at Princess Margaret Hospital, now Perth Children's Hospital. METHODS: Between January 2012 and June 2013 patients referred to Anaesthesia for a Peripherally Inserted Central Catheter were prospectively followed up. A repeat audit was conducted between January 2015 and June 2016, following the introduction of a number of measures aimed at improving the service. RESULTS: Audit 1: A total of 200 Peripherally Inserted Central Catheter insertions were attempted in 138 patients. Successful placement occurred in 86% of cases (172/200). The median age of patients was 7.71 years (range 0-20). The percentage of Peripherally Inserted Central Catheters remaining in situ for the predicted duration was 49/172 (28.5%). Complications were documented in 78/172 (45.4%) of cases. Audit 2: A total of 310 Peripherally Inserted Central Catheter placements were attempted in 244 patients. Successful insertion rate was 95.5% (296/ 310). The median age of patients was 5.3 years (range 0.0-18.72). The percentage remaining in situ for the predicted duration was 145/296 (49%). Complications were documented in 67/296 (22.6%) of cases. CONCLUSION: The evolution of the Peripherally Inserted Central Catheter service at our free standing Tertiary Paediatric Hospital is well documented following these 2 audits. The introduction of a dedicated Anaesthesia led Peripherally Inserted Central Catheter service at our centre has resulted in improved insertion success rates and a reduction in complications.

Cost analysis comparison between peripherally inserted central catheters and implanted chest ports in patients with cancer-A health economic evaluation of the PICCPORT trial.

BACKGROUND: A reliable central venous access device is a cornerstone in the treatment of cancer. Both peripherally inserted central catheters (PICC) and totally implanted chest ports (PORT) are commonly used for the delivery of chemotherapy. Both types of catheter can cause adverse events such as catheter-related deep venous thrombosis (CR-DVT), infection and mechanical complications. METHOD: We conducted a randomized controlled trial including 399 patients with cancer and performed a health economic evaluation investigating the cost related to PICCs and PORTs using several clinically relevant dimensions from a healthcare perspective. The cost was determined using process and cost estimate models. RESULT: PICCs are associated with a higher total cost when compared with PORTs. Combining the costs of all categories, the prize per inserted device was 824.58 EUR for PICC and 662.34 EUR for PORT. When adjusting for total catheter dwell time the price was 6.58 EUR/day for PICC and 3.01 EUR/day for PORT. The difference in CR-DVT was the main contributor to the difference in cost. The daily cost of PICC is approximately twice to that of PORT. CONCLUSION: We have demonstrated that the cost from a healthcare perspective is higher in cancer patients receiving a PICC than to those with a PORT. The difference is driven mainly by the cost related to the management of adverse events. Our findings are relevant to anaesthetists, oncologists and vascular access clinicians and should be considered when choosing vascular access device prior to chemotherapy.

Global Pediatric Peripheral Intravenous Catheter Practice and Performance: A Secondary Analysis of 4206 Catheters.

PURPOSE: To describe worldwide characteristics, performance and risk factors of peripheral intravenous catheters (PIVCs), in pediatrics. DESIGN: A secondary, subgroup analysis of pediatric (<18 years) data was undertaken, using a global, cross-sectional study of PIVCs. Practice characteristics included: demographic, diagnostic, utility, management, performance and resources. Multivariate regression identified complication risks factors. RESULTS: Data from 4206 children in 278 hospitals across 47 countries. Most PIVCs (outside of Australia, New Zealand) were inserted by nurses (71%; n = 2950), with dedicated teams only common in North America (23.2%; n = 85). Large gauges (≤18G) were mostly used in South America, Europe and Africa. Regions predominantly placed 24G (49%; n = 2060) except in Australia and New Zealand, who more commonly placed 22G (38.7%; n = 192). The most common placement was the hand (51%; n = 2143), however North America, Australia and New Zealand frequently utilised the antecubital fossa (24.5%, n = 90; 21.4%; n = 106). Polyurethane dressings were most used (67.1%; 2822), and many were not clean, dry and intact (17.1%; n = 715). Over 8% of PIVCs were idle, with the highest rates in North America (21.2%; n = 78). PIVC local complication risk factors included: >2 years age (odds ratio [OR] > 1.58; 1.2-2.1); ambulance/emergency insertion (OR 1.65; 1.2-2.3); upper arm/antecubital placement (OR 1.44; 1.1-2.0); poor dressing integrity (OR 5.4; 4.2-6.9); and 24-72 h dwell (OR > 1.9; 1.3-2.6). CONCLUSIONS: There is global inconsistency in pediatric PIVC practice, which may be causing harm. CLINICAL IMPLICATIONS: Improvements in pediatric PIVC placement, dressings, and gauge selection are needed.

The Utility and Survivorship of Peripheral Intravenous Catheters Inserted in the Emergency Department.

STUDY OBJECTIVE: We compare the use and survivorship rate of peripheral intravenous catheters placed in the emergency department (ED) by insertion method. METHODS: We analyzed a prospective cohort of ED patients who received a peripheral intravenous catheter in the ED by ultrasonographically guided or landmark insertion. Research assistants recorded the uses of the ED-inserted catheters during the ED visit and hospitalization. Among subjects admitted, research assistants tracked catheter survivorship for 72 hours or hospital discharge, whichever came first. Research assistants documented reason for catheter removal and whether it was replaced during hospitalization. Premature removal was defined as catheters that were replaced because of mechanical failure, complication, or discomfort. We used multivariate binomial regression to estimate the relative risk of insertion method on premature removal and a Kaplan-Meier curve to compare survivorship duration by insertion method. RESULTS: A cohort of 1,174 patients with a mean age of 45 years and 63% female predominance was analyzed. Catheter use was 73% and 78% in the ED and hospital for the administration of fluids, medications, or contrast agents (and 96% if blood drawn for testing was included). Peripheral intravenous use did not differ significantly in the ED or hospital by insertion method. For 330 patients who were admitted, 132 of 182 patients (73%) in the ultrasonographically guided group and 117 of 148 (79%) in the landmark group had 72-hour catheter survival. Premature removal was not significantly more likely to occur if the catheter was inserted by the ultrasonographically guided method compared with the landmark one (relative risk 1.26; 95% confidence interval 0.88 to 1.80). CONCLUSION: ED-inserted peripheral intravenous catheters were frequently used in the ED and hospital. Peripheral intravenous use and hospital survivorship of ED-inserted peripheral intravenous catheters were similar by insertion method.

A retrospective study of the safety of over 100,000 peripherally-inserted central catheters days for parenteral supportive treatments.

The type of central vascular access device providers chosen for providing parenteral supportive treatments has evolved over the past years, going from routinely used centrally inserted catheters to a more recent trend of peripherally-inserted central catheters (PICCs) when expected treatment duration is less than 6 months. This multicenter retrospective study aimed to provide a comprehensive assessment of the safety of PICCs in administering parenteral supportive treatments. All adult inpatients and outpatients who had a PICC inserted for the administration of parenteral supportive treatments (i.e., parenteral nutrition, intravenous fluids, blood products, or antibiotics) between September 2007 and December 2014 in four public Italian hospitals were included. The primary outcome was PICC removal because of an adverse event (AE, defined as occlusion, exit-site infection, or symptomatic thrombosis). Among the 1,250 included patients, 178 PICC-related removals because of AEs (14.2%; 1.62 AEs per 1,000 PICC days) were reported. Rates of PICC removal because of occlusion, exit-site infection, and symptomatic thrombosis were 1.08, 0.32, and 0.23 per 1,000 PICC days, respectively. The median dwell-time between PICC insertion and its removal because of an AE was 67 days (interquartile range 28-180 days). Risk of PICC removal due to AE was higher with open-system PICCs [hazard ratio = 2.75, 95% confidence interval 1.52-4.96]. In this study, we found preliminary evidence that PICCs can be safely used to administer parenteral supportive treatments lasting up to 6 months. PICCs may be a relevant alternative to centrally inserted catheters for medium-term parenteral supportive treatments.

Factors affecting the first-attempt success rate of intravenous cannulation in older people.

AIMS AND OBJECTIVES: To determine the factors affecting the first-attempt success of peripheral intravenous catheter (PIVC) placement in older emergency department patients. BACKGROUND: In older patients who require intravenous treatment, establishing a PIVC as fast as possible is clinically important. DESIGN: This is a prospective, observational, descriptive study. METHODS: Using a data collection form, researchers questioned both the patient and the nurse performing the procedure in terms of patient- and operator-related factors. This study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines (See Supporting Information Appendix S1). RESULTS: A total of 472 patients were included in the final analyses. According to the logistic regression analysis, independent factors which affected first-attempt failure were found to be: choosing a nonupper extremity site for PIVC (OR: 4.72, 95% CI: 1.35-16.45, p-value: 0.015), history of difficult intravenous access (OR: 3.02, 95% CI: 1.72-5.29, p-value: <0.001), nurse having less than 2 years of professional experience (OR: 3.45, 95% CI: 2.00-5.97, p-value: <0.001), nonpalpable veins observed after the application of tourniquet (OR: 2.21, 95% CI: 1.10-4.41, p-value: 0.025), a moderate degree of difficulty anticipated by the nurse prior to the procedure (OR: 4.32, 95% CI: 2.31-8.08, p-value: <0.001) and a high degree of difficulty anticipated by the nurse prior to the procedure (OR: 8.41, 95% CI: 4.10-17.24, p-value: <0.001). CONCLUSION: Factors affecting first-attempt success rates in peripheral intravenous catheter placement in older emergency department patients may be listed as follows: the anticipated difficulty of the procedure rated by the nurse, previous history of a difficult intravenous cannulation, choosing a nonupper extremity site for cannulation, the level of experience of the nurse and the palpability of the vein. RELEVANCE TO CLINICAL PRACTICE: Healthcare providers should consider alternative methods in the presence of factors affecting first-attempt success in older emergency department patients.

Comparison of Complication Rates of Central Venous Catheters Versus Peripherally Inserted Central Venous Catheters in Pediatric Patients.

OBJECTIVES: The purpose of our study is to compare the rate of central line-associated blood stream infections and venous thromboembolism in central venous catheters versus peripherally inserted central catheters in hospitalized children. There is a growing body of literature in adults describing an increased rate of venous thromboembolisms and similar rates of central line-associated blood stream infection associated with peripherally inserted central catheters versus central venous catheters. It is not known if the rate of central line-associated blood stream infection and venous thromboembolism differs between peripherally inserted central catheters and central venous catheters in children. Based on current adult literature, we hypothesize that central line-associated blood stream infection rates for peripherally inserted central catheters and central venous catheters will be similar, and the rate of venous thromboembolism will be higher for peripherally inserted central catheters versus central venous catheters. DESIGN: This is a cohort study using retrospective review of medical records and prospectively collected hospital quality improvement databases. SETTING: Quaternary-care pediatric hospital from October 2012 to March 2016. PATIENTS: All patients age 1 day to 18 years old with central venous catheters and peripherally inserted central catheters placed during hospital admission over the study dates were included. Central venous catheters that were present upon hospital admission were excluded. The primary outcomes were rate of central line-associated blood stream infection and rate of venous thromboembolism. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 2,709 catheters included in the study, 1,126 were peripherally inserted central catheters and 1,583 were central venous catheters. Peripherally inserted central catheters demonstrated a higher rate of both infection and venous thromboembolism than central venous catheters in all reported measures. In multivariable analysis, peripherally inserted central catheters had increased association with central line-associated blood stream infection (odds ratio of 3.15; 95% CI, 1.74-5.71; p = 0.0002) and increased association with venous thromboembolism (odds ratio of 2.71; 95% CI, 1.65-4.45; p < 0.0001) compared with central venous catheters. CONCLUSIONS: Rates of central line-associated blood stream infection and venous thromboembolism were higher in hospitalized pediatric patients with peripherally inserted central catheters as compared to central venous catheters. Our study confirms the need for further investigation into the safety of central access devices to assist in proper catheter selection.

Vascular Access in Critically Ill Pediatric Patients With Obesity.

OBJECTIVES: Pediatric obesity is highly prevalent and has been associated with poor outcomes for hospitalized children. Vascular access is essential in critically ill patients. The aim of this study was to evaluate whether critically ill children with obesity are more likely to undergo vascular device insertion (excluding peripheral IV catheters) and develop related complications. DESIGN: Multi-institutional retrospective observational cohort study. SETTING: Ninety-four U.S. PICUs included in the Virtual Pediatric Systems, LLC database. PATIENTS: 120,272 unique patients 2 to less than 18 years old admitted between January 2009 and December 2014. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Patients were categorized into normal weight, overweight, and obese (class 1, 2, or 3); underweight patients were excluded. We used mixed-effects multivariable logistic regression to test body mass index category as an independent predictor of vascular device placement and associated complications, adjusted for age, sex, severity of illness, primary diagnosis, presence of a complex chronic condition, and admission related to trauma or surgery. A total of 73,964 devices were placed in 45,409 patients (37.8% of the total cohort received a vascular device). Most device types placed differed significantly by weight status. Subjects with class 3 obesity were less likely (odds ratio, 0.74; 95% CI, 0.67-0.81) to undergo placement of any device compared with normal weight patients. Patients with all classes of obesity were more likely to undergo placement of a peripherally inserted central catheter, with the strongest association in those with class 2 obesity (odds ratio, 1.26; 95% CI, 1.14-1.40). Class 1 and class 3 obesity were independent risk factors for developing a complication, with odds ratio of 1.31 (95% CI, 1.11-1.53) and 1.45 (95% CI, 1.07-1.99), respectively. CONCLUSIONS: Severe obesity is associated with decreased overall likelihood of placement of a vascular access device but increased likelihood of peripherally inserted central catheter placement and of device-related complications.

Utilization of Intravenous Catheters by Prehospital Providers during Pediatric Transports.

INTRODUCTION: Prehospital intravenous (IV) access in children may be difficult and time-consuming. Emergency Medical Service (EMS) protocols often dictate IV placement; however, some IV catheters may not be needed. The scene and transport time associated with attempting IV access in children is unknown. The objective of this study is to examine differences in scene and transport times associated with prehospital IV catheter attempt and utilization patterns of these catheters during pediatric prehospital encounters. METHODS: Three non-blinded investigators abstracted EMS and hospital records of children 0-18 years of age transported by EMS to a pediatric emergency department (ED). We compared patients in which prehospital IV access was attempted to those with no documented attempt. Our primary outcome was scene time. Secondary outcomes include utilization of the IV catheter in the prehospital and ED settings and a determination of whether the catheter was indicated based on a priori established criteria (prehospital IV medication administration, hypotension, GCS < 13, and ICU admission). RESULTS: We reviewed 1,138 records, 545 meeting inclusion criteria. IV catheter placement was attempted in 27% (n = 149) with success in 77% (n = 111). There was no difference in the presence of hypotension or median GCS between groups. Mean scene time (12.5 vs. 11.8 minutes) and transport time (16.9 vs. 14.6 minutes) were similar. Prehospital IV medications were given in 38.7% (43/111). One patient received a prehospital IV medication with no alternative route of administration. Among patients with a prehospital IV attempt, 31% (46/149) received IV medications in the ED and 23% (34/396) received IV fluids in the ED. Mean time to use of the IV in the ED was 70 minutes after arrival. Patients with prehospital IV attempt were more likely to receive IV medication within 30 minutes of ED arrival (39.1% vs. 19.0%, p = 0.04). Overall, 34.2% of IV attempts were indicated. CONCLUSIONS: Prehospital IV catheter placement in children is not associated with an increase in scene or transport time. Prehospital IV catheters were used in approximately one-third of patients. Further study is needed to determine which children may benefit most from IV access in the prehospital setting.

Arterial catheterisation in neonates can result in severe ischaemic complications but does not impair long-term extremity function.

AIM: We evaluated the incidence of arterial catheterisation and analysed the risk factors and the extent and outcome of ischaemic complications in neonates. METHODS: This was a retrospective cohort study of 1506 neonates admitted to two, ten-bed neonatal intensive care units (NICUs) at the Medical University of Vienna, Austria, between 1 January 2011 and 31 December 2014. Medical charts, daily reports and photo documentation were reviewed for arterial catheterisation and ischaemic complications. Patients with severe ischaemic complications were followed up to evaluate extremity function, scaring and cosmetic results. RESULTS: There were 542 arterial catheterisations in 485 patients, including 275 born below 28 weeks, which resulted in severe complications in 19 of 485 (4%) patients. Three died before follow-up. Patients with complications had a significantly lower birthweight, lower postmenstrual age and higher rates of intracranial haemorrhage, retinopathy of prematurity and necrotising enterocolitis. They had also undergone multiple arterial catheterisations more often, needed longer inotropic support and had longer NICU stays than patients without complications. Extremity function was unimpaired in ten of 16 patients with severe ischaemic complications. CONCLUSION: Severe ischaemic complications in neonates following arterial catheterisation were rare events, but could cause devastating damage. Most patients didn't show impaired extremity function at follow-up.

Improved Diagnosis and Treatment of Bone and Joint Infections Using an Evidence-based Treatment Guideline.

BACKGROUND: Our institution created a multidisciplinary guideline for treatment of acute hematogenous osteomyelitis (AHO) and septic arthritis (SA) in response to updates in evidence-based literature in the field and existing provider variability in treatment. This guideline aims to improve the care of these patients by standardizing diagnosis and treatment and incorporating up to date evidence-based research into practice. The primary objective of this study is to compare cases before versus after the implementation of the guideline to determine concrete effects the guideline has had in the care of patients with AHO and SA. METHODS: This is an Institutional Review Board-approved retrospective study of pediatric patients age 6 months to 18 years hospitalized between January 2009 and July 2016 with a diagnosis of AHO or SA qualifying for the guideline. Cohorts were categorized: preguideline and postguideline. Exclusion criteria consisted of: symptoms >14 days, multifocal involvement, hemodynamic instability, sepsis, or history of immune deficiency or chronic systemic disease. Cohorts were compared for outcomes that described clinical course. RESULTS: Data were included for 117 cases that qualified for the guideline: 54 preguideline and 63 postguideline. Following the successful implementation of the guideline, we found significant decrease in the length of intravenous antibiotic treatment (P<0.001), decrease in peripherally inserted central catheter use (P<0.001), and an increase in bacterial identification (P=0.040). Bacterial identification allowed for targeted antibiotic therapy. There was no change in length of hospital stay or readmission rate after the implementation of the guideline. CONCLUSION: Utilizing an evidence-based treatment guideline for pediatric acute hematogenous bone and joint infections can lead to improved bacterial diagnosis and decreased burden of treatment through early oral antibiotic use. LEVEL OF EVIDENCE: Level III- retrospective comparative study.

An evaluation of management of transferred paediatric burn patients.

The aim of study was to evaluate whether adequate initial management and safe transfer of paediatric burn patients was carried out in our setup. Patients transferred from other hospitals/ cities to Paediatric Surgery Department, Mayo Hospital were evaluated in this prospective study. Data was entered in a proforma. Around 90.4% patients on presentation had discrepancy in their burn percentage calculation. No intravenous fluids were administered to 75.4% patients and 71.1% patients did not have any intravenous access. Foley's catheter was inserted in 2 patients only though 72.8% needed it. No fasciotomy was performed in 10.5% patients needing it. Two patients needed endotracheal intubation but it was not passed, 49.1% patients were transferred by ambulance and 28.9% patients presented with sepsis. The mortality rate was 38.2%. Initial fluid resuscitation was compared with survival and found significant (p=0.000). This shows that initial burn management, transfer system and referral system is full of errors.
