Abstract
OBJECTIVES This study aimed to improve the accuracy of Broselow tape (BT) weight prediction by adding midthigh circumference (MTC) and to compare and standardize the methods for measuring MTC. METHODS This prospective, observational study was conducted in a pediatric emergency department of a tertiary care children's hospital. Children up to 12 years of age presenting to emergency department were included. Children were excluded if obtaining the data would interfere with their acute management. The data collected included MTC, height, BT weight, and actual weight. Three models were built. Broselow tape-only model and MTC plus BT model used 2 methods for MTC measurements: visual approximation of thigh midpoint (visual MTC1) and Centers for Disease Control and Prevention (CDC)-defined method (CDC MTC2). RESULTS A total of 430 children were enrolled during pre-coronavirus disease era. Of these, 234 were boys (54.4%) and 196 (45.6%) were girls. Data were categorized into children younger than 2 years (224 [52.1%]) and older than 2 years (206 [47.9%]). African American constituted 250 (58%); White, 136 (31%); and unspecified, 27 (6%). For the entire cohort, both models that included MTC were significantly better at weight prediction with larger adjusted R2 (visual MTC1, 0.921; CDC MTC2, 0.928) and smaller root mean squared (RMSE) (visual MTC1, 2.70; CDC MTC2, 2.56) compared with BT-only model (adjusted R2 = 0.843; RMSE, 3.80). Midthigh circumference plus BT models performed even better in children older than 2 years compared with BT-only model with adjusted R2 (visual MTC1, 0.859; CDC MTC2, 0.872 vs 0.616) and RMSE (visual MTC1, 3.18; CDC MTC2, 3.03 vs 5.27). CONCLUSIONS The inclusion of MTC with BT resulted in a more accurate weight prediction in children especially greater than 2 years old. Midthigh circumference model using CDC-defined method was slightly better predictor of actual weight than visual approximation.

Abstract
Anthropometric profiles are important indices for assessing medical conditions, including malnutrition, obesity, and growth disorders. Noncontact methods for estimating those parameters could have considerable value in many practical situations, such as the assessment of young, uncooperative infants or children and the prevention of infectious disease transmission. The purpose of this study was to investigate the feasibility of obtaining noncontact anthropometric measurements using the impulse-radio ultrawideband (IR-UWB) radar sensor technique. A total of 45 healthy adults were enrolled, and a convolutional neural network (CNN) algorithm was implemented to analyze data extracted from IR-UWB radar. The differences (root-mean-square error, RMSE) between values from the radar and bioelectrical impedance analysis (BIA) as a reference in the measurement of height, weight, and body mass index (BMI) were 2.78, 5.31, and 2.25, respectively; predicted data from the radar highly agreed with those from the BIA. The intraclass correlation coefficients (ICCs) were 0.93, 0.94, and 0.83. In conclusion, IR-UWB radar can provide accurate estimates of anthropometric parameters in a noncontact manner; this study is the first to support the radar sensor as an applicable method in clinical situations.

Abstract
OBJECTIVE To assess the validity of the Broselow tape in estimating the weight of Chinese children in pediatric emergency. METHODS A cross-sectional study was conducted in the emergency department of the Children's Hospital of Zhejiang University School of Medicine (Hangzhou, Zhejiang Province, China) in March 2022. Broselow tape was used to estimate weight and its validity was compared with the advanced child life support (APLS) method. RESULTS The study included 442 children (mean age: 48 months; male-to-female ratio: 1.13:1). The < 10, 10-19 and > 19-kg groups included 44, 257, and 141 children, respectively. The color concordance rates of the Broselow tape-estimated weight in the three groups were 56.8, 57.2, and 68.1%, respectively. The percentage of weight estimations within 10% of actual weight were 65.8% (59.1, 65.8, and 68.1% for the <10, 10-19 and > 19-kg groups, respectively) and 44.8% (40.9, 50.6, and 35.5% for the < 10, 10-19 and > 19-kg groups, respectively) using the Broselow tape and the APLS method, respectively. The correlation between the Broselow tape estimated weight and actual weight was r = 0.931 (P < 0.0001, 95% CI: 0.918-0.943), while the correlation between actual weight and the APLS method calculated weight was r = 0.883 (P < 0.0001, 95% CI: 0.861-0.902). The mean percentage error using the Broselow tape was 1.0 ± 12.0% (P < 0.001 vs. -7.2 ± 17.2% of the APLS method). CONCLUSION The Broselow tape may be an available method for predicting the weights of Chinese children in pediatric emergency.

Interventions to Reduce Pediatric Prescribing Errors in Professional Healthcare Settings: A Systematic Review of the Last Decade. Paediatr Drugs 2021; 23:223-240. [PMID: 33959936 DOI: 10.1007/s40272-021-00450-6] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 04/16/2021] [Indexed: 10/21/2022]
Abstract
INTRODUCTION Pediatric medication therapy is prone to errors due to the need for pharmacokinetic and pharmacodynamic individualization and the diverse settings in which pediatric patients are treated. Prescribing errors have been reported as the most common medication error. OBJECTIVES The aim of this review was to systematically identify interventions to reduce prescribing errors and corresponding patient harm in pediatric healthcare settings and to evaluate their impact. METHODS Four databases were systematically screened (time range November 2011 to December 2019), and experimental studies were included. Interventions to reduce prescribing errors were extracted and classified according to a 'hierarchy of controls' model. RESULTS Forty-five studies were included, and 70 individual interventions were identified. A bundle of interventions was more likely to reduce prescribing errors than a single intervention. Interventions classified as 'substitution or engineering controls' were more likely to reduce errors in comparison with 'administrative controls', as is expected from the hierarchy of controls model. Fourteen interventions were classified as substitution or engineering controls, including computerized physician order entry (CPOE) and clinical decision support (CDS) systems. Administrative controls, including education, expert consultations, and guidelines, were more commonly identified than higher level controls, although they may be less likely to reduce errors. Of the administrative controls, expert consultations were most likely to reduce errors. CONCLUSIONS Interventions to reduce pediatric prescribing errors are more likely to be successful when implemented as part of a bundle of interventions. Interventions including CPOE and CDS that substitute risks or provide engineering controls should be prioritized and implemented with appropriate administrative controls including expert consultation.

Interventions to Reduce Medication Dispensing, Administration, and Monitoring Errors in Pediatric Professional Healthcare Settings: A Systematic Review. Front Pediatr 2021; 9:633064.

Abstract
Introduction: Pediatric patients cared for in professional healthcare settings are at high risk of medication errors. Interventions to improve patient safety often focus on prescribing; however, the subsequent stages in the medication use process (dispensing, drug administration, and monitoring) are also error-prone. This systematic review aims to identify and analyze interventions to reduce dispensing, drug administration, and monitoring errors in professional pediatric healthcare settings. Methods: Four databases were searched for experimental studies with separate control and intervention groups, published in English between 2011 and 2019. Interventions were classified for the first time in pediatric medication safety according to the "hierarchy of controls" model, which predicts that interventions at higher levels are more likely to bring about change. Higher-level interventions aim to reduce risks through elimination, substitution, or engineering controls. Examples of these include the introduction of smart pumps instead of standard pumps (a substitution control) and the introduction of mandatory barcode scanning for drug administration (an engineering control). Administrative controls such as guidelines, warning signs, and educational approaches are lower on the hierarchy and therefore predicted by this model to be less likely to be successful. Results: Twenty studies met the inclusion criteria, including 1 study of dispensing errors, 7 studies of drug administration errors, and 12 studies targeting multiple steps of the medication use process. A total of 44 interventions were identified. Eleven of these were considered higher-level controls (four substitution and seven engineering controls). The majority of interventions (n = 33) were considered "administrative controls" indicating a potential reliance on these measures. Studies that implemented higher-level controls were observed to be more likely to reduce errors, confirming that the hierarchy of controls model may be useful in this setting. Heterogeneous study methods, definitions, and outcome measures meant that a meta-analysis was not appropriate. Conclusions: When designing interventions to reduce pediatric dispensing, drug administration, and monitoring errors, the hierarchy of controls model should be considered, with a focus placed on the introduction of higher-level controls, which may be more likely to reduce errors than the administrative controls often seen in practice.

Abstract
Introduction Introduction: in emergencies or in situations involving critically ill patients, an accurate calculation of body weight is essential to ensure adequate medical care. Generally, simple techniques are used to determine weight. Aim: to evaluate the weight estimation methods Advanced Paediatric Life Support (APLS) Update, Luscombe and Owens, Best Guess, and the Broselow tape, comparing measured weight with the weight estimated by each method in hospitalized Brazilian children and adolescents. Methods: an observational study in which anthropometric data were collected from patients of 0-14 years of age between August 2016 and January 2017. The paired t-test was used to compare the patients' measured weight with their estimated weight. The accuracy of each method was analyzed using Bland-Altman plots and Lin's concordance correlation coefficient. Results: the sample consisted of 446 patients. Most of the patients were male (58.1%), of 1-5 years of age (43%) and well nourished (85%). For those under 12 months of age, the APLS Update and Best Guess methods performed best, with the difference in means of measured weight and estimated weight being 0.4 kg (p = 0.183) and -0.2 kg (p = 0.140), respectively. In the 1-5 years of age group only the APLS Update yielded satisfactory results (0.2 kg; p = 0.200). The best agreement with measured weight, according to the Bland-Altman plots and Lin's coefficient, was found for the Broselow tape (CC = 0.96). Conclusion: of the estimation methods evaluated the Broselow tape was the most accurate one. Further studies are required to adapt this method for use in the Brazilian population, thus ensuring its appropriate application in this country.

Abstract
OBJECTIVE Pediatric emergency tapes have been developed to support paramedics and emergency physicians when dosing drugs and selecting medical equipment in pediatric emergency situations. The aim of this study was to compare the accuracy of 4 pediatric emergency tapes to correctly estimate patient's weight based on a large population of patients. METHODS Patients undergoing general anesthesia between January 2012 and March 2015 with documented age, sex, body weight, and length were identified from the electronic anesthesia patient data management system of the Department of Anaesthesia, University Children's Hospital, Zurich, Switzerland. Weight estimation by means of the Broselow-Tape, the Pädiatrisches Notfalllineal, the Paulino System, and the Kinder-Sicher were compared with true patient's weight. Percentages of estimated body weight within a ±10% and ±20% interval were calculated. Data are median (interquartile range) or count (percent); statistical calculations were done with McNemar and Bonferroni correction. RESULTS A total of 3307 patients were identified with complete data sets, 1930 (58.4%) were male, median age was 4.1 years (1.1-8.2 years), median length 101.0 cm (74.0-126.0 cm) and median patient weight 15.8 kg (9.2-25.0 kg). The proportion weight estimation within the ±10% and the ±20% interval was the highest in the Broselow-Tape with 54.0% and 81.5% (P < 0.001 and P = 0.003), followed by the Pädiatrisches Notfalllineal (50.5% and 79.8%), Paulino System (49.9% and 78.0%) and Kinder-Sicher (48.2% and 77.5%). CONCLUSIONS The overall accuracy of all 4 emergency tapes tested is poor and including a larger number of weight categories does not necessarily increase accuracy. Other strategies have to be developed to improve weight estimation in pediatric emergency situations.

Abstract
OBJECTIVES Obtaining accurate pediatric weight is necessary during emergency resuscitation. Although several weight estimation methods exist, the most precise method has not been conclusively determined. This study aimed to evaluate the validity, reliability, and practicality of these tools. METHODS A prospective observational study was conducted in healthy Thai children aged 6 months to 12 years. Correlations between estimated and actual weights were tested. Validity was assessed by mean bias (estimated weight minus actual weight) and accuracy (10% error). Practicality was evaluated by time usage and data derived from user questionnaires. RESULTS Four hundred thirty participants with mean age of 6.7 years and mean weight of 26 kg were enrolled. A strong correlation between estimated weight and actual weight in all methods was demonstrated. Parental estimation was the most accurate tool in all age groups, with the lowest overall mean error (ME) of -0.83 kg and the highest accuracy of 88.7%. The Broselow tape was the second most accurate tool in ages younger than 1 year and 1-to-5-year age groups (ME = 0.23 and 0.50 kg; accuracy = 55.3% and 54.1%, respectively). The Mercy method was the second most accurate tool in the 6-to-10-year and 11-to-12-year age groups (ME = -2.47 and -2.77; accuracy = 54.6% and 67.9%, respectively). The Broselow tape had the highest score for practicality of use. CONCLUSIONS Parental estimation was the most accurate method in every age group. The next best alternative is the Broselow tape in children aged 5 years or younger and the Mercy method in children aged older than 5 years.

Abstract
AIMS The Broselow tape is widely used as a weight-estimation device and drug-dosing guide aid, but concerns about its accuracy and its efficacy have emerged in the last decade. The aim of this study was to systematically review the literature to analyse the accuracy of the Broselow tape as a weight estimation device and review evidence of its utility as a drug-dosing guide. METHODS This was a MOOSE-driven systematic review and meta-analysis, which focused on studies evaluating the accuracy of the Broselow tape and studies reviewing its use as a drug-dosing aid. MAIN RESULTS The tape has undergone substantial changes over the years, but there was no evidence to show that the changes have improved weight-estimation performance. The weight-estimation accuracy of the tape was suboptimal in all populations, with just over 50% of children receiving an estimation within 10% of their actual weight. The overestimation of weight in low- and middle-income countries was often extreme. This indicated a significant potential for potentially harmful medication errors. The limited available evidence on the value of the tape as a drug-dosing guide indicated that the tape was frequently used incorrectly and contained insufficient information to function without additional resources. CONCLUSIONS The Broselow tape lacked sufficient accuracy as a weight estimation and drug-dosing tool when compared to other available techniques. In addition, the Broselow tape contains insufficient drug-dosing information to function as a complete resuscitation aid without additional material. The frequent rate of incorrect usage of the tape indicated that appropriate training with the tape is mandatory to reduce errors.

A systematic review and meta-analysis of the accuracy of weight estimation systems used in paediatric emergency care in developing countries. Afr J Emerg Med 2017; 7:S36-S54. [PMID: 30505673 PMCID: PMC6246873 DOI: 10.1016/j.afjem.2017.06.001] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2017] [Revised: 06/13/2017] [Accepted: 06/29/2017] [Indexed: 11/23/2022] Open
Abstract
Introduction When weight cannot be measured during the management of medical emergencies in children, a convenient, quick and accurate method of weight estimation is required, as many drug doses and other interventions are based on body weight. Many weight estimation methodologies in current use have been shown to be inaccurate, especially in low- and middle-income countries with a high prevalence of underweight children. This meta-analysis evaluated the accuracy of weight estimation systems in children from studies from low- and middle-income countries. Methods Articles from low- and middle-income countries were screened for inclusion to evaluate and compare the accuracy of existing systems and the newer dual length- and habitus-based methods, using standard meta-analysis techniques. Results The 2D systems and parental estimates performed best overall. The PAWPER tape, parental estimates, the Wozniak method and the Mercy method were the most accurate systems with percentage of weight estimates within 10% of actual weight (PW10) accuracies of 86.9%, 80.4%, 72.1% and 71.4% respectively. The Broselow tape (PW10 47.1%) achieved a moderate accuracy and age-based estimates a very low accuracy (PW10 11.8–47.5%). Conclusions The PAWPER tape, the Wozniak method and the Mercy method achieved an acceptable level of accuracy in studies from low- and middle-income countries and should preferentially be used and further advanced for clinical emergency medicine practice. Parental estimates may be considered if the regular caregiver of the child is present and a recent measured weight is known. The Broselow tape and age-based formulas should be abandoned in low- and middle-income country populations as they are potentially dangerously inaccurate.

Abstract
The safe and effective administration of fluids and medications during the management of medical emergencies in children depends on an appropriately determined dose, based on body weight. Weight can often not be measured in these circumstances and a convenient, quick and accurate method of weight estimation is required. Most methods in current use are not accurate enough, but the newer length-based, habitus-modified (two-dimensional) systems have shown significantly higher accuracy. This meta-analysis evaluated the accuracy of weight estimation systems in children. Articles were screened for inclusion into two study arms: to determine an appropriate accuracy target for weight estimation systems; and to evaluate the accuracy of existing systems using standard meta-analysis techniques. There was no evidence found to support any specific goal of accuracy. Based on the findings of this study, a proposed minimum accuracy of 70% of estimations within 10% of actual weight (PW10 > 70%), and 95% within 20% of actual weight (PW20 > 95%) should be demonstrated by a weight estimation system before being considered to be accurate. In the meta-analysis, the two-dimensional systems performed best. The Mercy method (PW10 70.9%, PW20 95.3%), the PAWPER tape (PW10 78.0%, PW20 96.6%) and parental estimates (PW10 69.8%, PW20 87.1%) were the most accurate systems investigated, with the Broselow tape (PW10 55.6%, PW20 81.2%) achieving a lesser accuracy. Age-based estimates achieved a very low accuracy. Age- and length-based systems had a substantial difference in over- and underestimation of weight in high-income and low- and middle-income populations. A benchmark for minimum accuracy is recommended for weight estimation studies and a PW10 > 70% with PW20 > 95% is suggested. The Mercy method, the PAWPER tape and parental estimates were the most accurate weight estimation systems followed by length-based and age-based systems. The use of age-based formulas should be abandoned because of their poor accuracy.

Safety Threats During the Care of Infants with Hypoglycemic Seizures in the Emergency Department: A Multicenter, Simulation-Based Prospective Cohort Study. J Emerg Med 2017; 53:467-474.e7. [PMID: 28843460 DOI: 10.1016/j.jemermed.2017.04.028] [Citation(s) in RCA: 19] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2016] [Revised: 03/19/2017] [Accepted: 04/25/2017] [Indexed: 11/18/2022]
Abstract
BACKGROUND Errors in the timely diagnosis and treatment of infants with hypoglycemic seizures can lead to significant patient harm. It is challenging to precisely measure medical errors that occur during high-stakes/low-frequency events. Simulation can be used to assess risk and identify errors. OBJECTIVE We hypothesized that general emergency departments (GEDs) would have higher rates of deviations from best practices (errors) compared to pediatric emergency departments (PEDs) when managing an infant with hypoglycemic seizures. METHODS This multicenter simulation-based prospective cohort study was conducted in GEDs and PEDs. In situ simulation was used to measure deviations from best practices during management of an infant with hypoglycemic seizures by inter-professional teams. Seven variables were measured: five nonpharmacologic (i.e., delays in airway assessment, checking dextrose, starting infusion, verbalizing disposition) and two pharmacologic (incorrect dextrose dose and incorrect dextrose concentration). The primary aim was to describe and compare the frequency and types of errors between GEDs and PEDs. RESULTS Fifty-eight teams from 30 hospitals (22 GEDs, 8 PEDs) were enrolled. Pharmacologic errors occurred more often in GEDs compared to PEDs (p = 0.043), while nonpharmacologic errors were uncommon in both groups. Errors more frequent in GEDs related to incorrect dextrose concentration (60% vs. 88%; p = 0.025), incorrect dose (20% vs. 56%; p = 0.033), and failure to start maintenance dextrose (33% vs. 65%; p = 0.040). CONCLUSIONS During the simulated care of an infant with hypoglycemic seizures, errors were more frequent in GEDs compared to PEDs. Decreasing annual pediatric patient volume was the best predictor of errors on regression analysis.

An Assessment of Newly Identified Barriers to and Enablers for Prehospital Pediatric Pain Management. Pediatr Emerg Care 2017; 33:381-387. [PMID: 26414634 DOI: 10.1097/pec.0000000000000514] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/26/2022]
Abstract
OBJECTIVES The aim of this study was to quantitatively assess the prevalence of newly identified barriers and enablers to prehospital narcotic analgesic administration in a sample of paramedics and determine whether these barriers and enablers differ between new and experienced paramedics. METHODS We surveyed a convenience sample of paramedics from urban, suburban, and rural practice settings in an emergency medical services system. Descriptive statistics were calculated to describe responses, and differences between new (≤5 years) and experienced (>5 years) providers were assessed. RESULTS There were 127 surveys analyzed; 67% of our sample was experienced and 86% considered treating pain important. Notable barriers for analgesic administration include causing more pain from intravenous catheter insertion, parental influences, difficulty assessing pain, and worry about allergic reactions. Notable enablers include belief that analgesic administration is important, education to administer analgesics, and support from agency leadership. There were statistically significant differences between new and experienced providers in the distribution of responses for survey items regarding how the importance of treating pain in children was learned, overall comfort with pediatric patients, receiving negative responses from superiors about giving pediatric patients analgesics, and usefulness of the Broselow tape for dosing fentanyl for children. Other barriers and enablers were not significantly different between new and experienced providers. CONCLUSIONS Top barriers to prehospital pediatric analgesic administration are related to skills and knowledge deficits, whereas enablers include support from agency leadership and personal views on analgesics. This information can be used to guide interventions to improve the management of pain in children.

Abstract
BACKGROUND Pediatric emergencies are rare and challenging for health care providers, parents, and patients. The purpose of this article is to highlight typical difficulties in the treatment of pediatric patients and to discuss potential solutions. MATERIALS AND METHODS This article is based on a selective literature search using PubMed and the experience of the authors in the field of simulation and pediatric emergencies. RESULTS Inexperience with pediatric emergencies, uncertainty in technical skills, in the usage of pediatric equipment and in medication dosage as well as parental presence foster the perception of stress and potentially compromise the success of patient care. Beside implementation of simplified technical skill devices (e.g., intraosseous vascular access system, supraglottic airway devices, and alternative approaches for drug administration), there have been many efforts in recent years to improve patient safety. Tools for estimating body weight and precalculated drug-dosing charts have been implemented as well as standardized courses for guidelines, technical skills, and team-related skills have been established. CONCLUSION To improve patient safety, regular training and implementation of a sustainable safety culture are mandatory.

Abstract
It is important that pediatric critical care nurses possess a thorough understanding of their patient and be able to provide exceptional care, especially during emergent situations in the operating room. This care is accomplished by assessing the pediatric patient, dosing medications accurately and effectively, and performing effective Pediatric Advanced Life Support. Pediatric patients present with unique anatomy, physiology, and pathophysiology. Emergencies are reviewed according to organ system, with a focus on definition, presentation, pathophysiology, management, and special considerations.
