Inhaled corticosteroid prescriptions in the ED for recurrent asthma using IT clinical decision support: revisit after cessation of an incentive program.

INTRODUCTION: The objective of this study was to assess whether inhaled corticosteroid (ICS) prescription rates for patients with poorly controlled asthma presenting to the emergency department (ED) remained high with a clinical support system in place, after a financial incentive program ended. This study is the second phase of a previous study done at our institution. The first phase demonstrated that the introduction of an electronic alert system advising providers to prescribe ICS to patients with poorly controlled asthma, along with a financial incentive, increased ICS prescription rates from 2% to 77%. Clinical support systems are necessary to improve control for patients with asthma, as prescribing ICS in the ED has not previously been standard of care. METHODS: This retrospective study identified 96 eligible patients during the study period of January 1, 2019 to December 31, 2019. Subjects included patients aged 4-18 with at least two ED visits for asthma within 365 days and no recent ICS prescription. For subjects meeting these criteria, an electronic alert activated, advising the provider to prescribe ICS. RESULTS: ICS prescription rate without the incentive remained high at 0.74 (0.59, 0.86) and was not significantly different than the rate with the incentive of 0.77 (0.65, 0.87), with p value 0.82. No significant differences were detected in baseline characteristics between patients discharged with and without an ICS prescription. CONCLUSIONS: This study confirmed that an electronic alert advising ICS prescription in the ED for patients with recurrent asthma visits is effective, even without a financial incentive.

Pediatric Emergency Department Return Visits Within 72 Hours: Caregivers' Motives and Analysis of Ethnic and Primary Language Disparities.

OBJECTIVES: In the United States, approximately 2.2% to 5% of children discharged from the emergency department (ED) return within 72 hours. There is limited literature examining caregivers' reasons for return to the ED, and none among Hispanics and Spanish-speaking caregivers. We sought to examine why caregivers of pediatric patients return to the ED within 72 hours of a prior ED visit, and assess roles of ethnicity and primary language. METHODS: A previously validated survey was prospectively administered to caregivers returning to the ED within 72 hours of discharge at a freestanding, tertiary care, children's hospital over a 7-month period. Reasons for return to the ED, previous ED discharge processes, and events since discharge were summarized according to Hispanic ethnicity, and English or Spanish language preference, and compared using the Fisher exact test. RESULTS: Among 499 caregiver surveys analyzed, caregivers returned mostly because of no symptom improvement (57.5%) and worsening condition (35.5%), with no statistically significant differences between Hispanic/non-Hispanic ethnicity, or English/Spanish preference. Most (85.2%) caregivers recalled reasons to return to the ED. Recall of expected duration until symptom improvement was significantly higher among Hispanic (60.4%) versus non-Hispanic (52.1%) (P = 0.003), and for Spanish- (68.9%) versus English-speaking (54.6%) (P = 0.04), caregivers. CONCLUSIONS: Most caregivers returned to the ED because their child's condition was not better or had worsened. Ethnicity and language were not associated with variations in reasons for return. Non-Hispanic and English-speaking caregivers were less likely to recall being informed of time to improvement and may require additional intervention.

Measuring the Quality of Cardiopulmonary Resuscitation in the Emergency Department at a Quaternary Children's Hospital.

AIM OF STUDY: The aim of this study was to evaluate the quality of cardiopulmonary resuscitation (CPR) as it relates to American Heart Association (AHA) guidelines during cardiac arrests in a pediatric emergency department at a quaternary children's hospital. BACKGROUND AND OBJECTIVES: High-quality CPR increases the likelihood of survival from pediatric out-of-hospital cardiac arrest. However, optimal performance of high-quality CPR during transition of care between prehospital and pediatric emergency department providers is challenging, and survival without comorbidities remains extremely low for out-of-hospital cardiac arrest. METHODS: This was a retrospective study of data collected from a free-standing children's hospital emergency department and level 1 trauma center. RESULTS: There were 23 pediatric CPR events for subjects younger than 18 years in the emergency department during the time of the study. Median chest compression (CC) fraction was 85% overall with the AHA goal of 80%. Compliance with this recommendation was achieved in all age groups. The CC rate averaged 112 for the entire sample. Median depth was 2.06 cm in subjects younger than 1 year, 3.95 cm in subjects 1 year old to younger than 8 years, and 5.33 cm in subjects 8 years old to younger than 18 years. These compression depth rates fell below the AHA recommendations, with the exception of those 8 years and older. CONCLUSIONS: In our study, CC fraction and CC rate were found to meet AHA targets for all age groups, whereas CC depth only met AHA targets for the 8- to 18-year-old group. The most difficult parameter was CC depth for the group of subjects younger than 1 year.

Inhaled corticosteroids prescriptions increased in the ED for recurrent asthma exacerbations by automated electronic reminders in the ED.

Objective: The objective of this study was to evaluate the impact of an electronic alert on the prescription rate of inhaled corticosteroids (ICS) by ED providers for poorly controlled persistent asthmatic children.Methods: Study subjects included asthmatic patients age 4-18 presenting to the ED at Phenix Children's Hospital between February 9, 2018 and December 4, 2018, with a history of at least two previous ED visits for acute exacerbation of asthma within 365 days, no active ICS prescription within 90 days, and free from developmental delay, bronchopulmonary dysplasia due to prematurity, cystic fibrosis, sickle cell disease, and/or interstitial ling disease. Patients meeting these criteria triggered an electronic alert prompting the medical provider to prescribe ICS or indicate reason for not prescribing. Instruction on the alert was provided to ED attending physicians and residents by email and through several educational sessions held prior to the implementation.Results: Among 62 patients without prior ICS who were discharged home from the ED, ICS was prescribed for 48 (77%). No statistically significant differences were detected in baseline characteristics between patients discharged home from the ED with and without ICS prescription. While ICS was prescribed by a larger proportion of physicians (56%) compared to residents (42%), statistical significance was not reached. For the 14 (33%) patients who were discharged home without ICS, no reason was provided to indicate why ICS were not prescribed.Conclusion: An electronic alert incorporated into the ED workflow to populate a discharge order set is effective to initiate asthma controller medication for poorly controlled pediatric patients. Additional data describing reasons for not prescribing ICS can further refine recommendations for ICS prescriptions, and provide a comprehensive strategy to support clinical decision for pediatric asthma control in acute care settings.

Comparison of Prehospital Calculated Age-Adjusted Pediatric Shock Index (SIPA) to Those Calculated in the ED for Identifying Trauma Patients That Needed the Highest-Level Activation Based on Consensus Criteria.

Background: The shock index (SI) is defined as the ratio of the heart rate to systolic blood pressure and a pediatric age-adjusted SI (SIPA) is more specific than the standard adult cutoff of 0.9 in identifying the sickest children presenting to a trauma center.Goal: To utilize prehospital vital signs to calculate the SIPA score and compare them to the SIPA calculated in the trauma bay to determine if they have the same validity in identifying critically ill children as determined by the consensus based standard criteria for trauma activation.Methods: Retrospective study using a cohort of patients transferred by EMS to a free standing, urban, level one, pediatric trauma center aged 1 to 16 years inclusive, and seen between January 1, 2016 and December 31, 2017. Vital signs collected during the patch call from the EMS agency were used to calculate the EMS SIPA. The first set of vital signs collected in the trauma bay was used to calculate the ED SIPA. Patients were dichotomized to an elevated or non-elevated ED SIPA and an elevated or non-elevated EMS SIPA.Results: Our cohort consisted of 2651 patients. 546 (20.6%) patients had an elevated EMS SIPA and 438 (16.5%) had an elevated ED SIPA. When compared to their non-elevated counterparts, EMS and ED SIPA were both able to identify patients who met consensus criteria in all areas except the need for IR intervention, and unstable spinal fracture/spinal cord injury. For these criteria, the ED SIPA was better than the EMS SIPA. Sensitivity and specificity analysis reveal poor sensitivity for both measures but a high specificity for ED and EMS SIPA. Both SI and SIPA have a poor PPV but high NPV.Conclusions: This study utilized prehospital vital signs to calculate the SIPA score and compare them to the SIPA calculated in the trauma bay. Both scores had similar test metrics when based on the consensus based standard trauma criteria and could be utilized in the triage traumatic injuries.

Success Rates for Reduction of Pediatric Distal Radius and Ulna Fractures by Emergency Physicians.

BACKGROUND: Emergency physicians are trained in urgent fracture reduction. Many hospitals lack readily available in-house orthopedic coverage. OBJECTIVES: The aim of this study was to determine success rates for reduction of pediatric distal radius or ulna fractures by emergency department (ED) physicians. METHODS: We conducted a retrospective study of children younger than 18 years presenting to a large, urban, freestanding children's hospital from January 1, 2009, to December 31, 2010, with forearm fracture. Exclusions included open fracture, those requiring immediate surgical intervention, or additional fractures. The primary end point was the proportion of successful closed forearm fracture reductions in the ED, as defined by orthopedic follow-up. RESULTS: All reductions were performed by a board-certified/eligible pediatric emergency medicine (PEM) physician or PEM fellow. Two hundred ninety-five fractures were reduced in the ED during the study period. Mean age was 8.27 years (median, 8 years; range, 1-16 years), and males comprised 69.2% (n = 204). A total of 222 fractures (76%) were of the distal forearm, and 70 involved the midshaft (24%). Orthopedic follow-up was completed in 77.3%. A total of 33 patients (11%) required remanipulation; 24 in the distal forearm fracture group (22 closed reductions, 2 open reductions with internal fixation) versus 9 in the midshaft group (7 closed reductions, 2 open reductions with internal fixation) (P = 0.948). CONCLUSIONS: The literature reveals 7% to 39% of children with fracture reductions performed in the ED by orthopedic surgeons/residents require remanipulation. Our rate of 11% is consistent within that range. With training, PEM physicians have similar success rates as orthopedists in forearm fracture reductions.

Prehospital Analgesic Administration by Parents for Pain Relief in Children.

PURPOSE: Undertreatment of pain by caregivers before presentation to the pediatric emergency department (ED) has been well documented. What has yet to be elucidated are the reasons why caregivers fail to adequately treat pain before arrival in the ED and whether there are differences based on ethnic background or age of the child. The objectives of this study were to determine the barriers to giving pain medication for injuries before ED arrival and to determine if there are any ethnic- or age-related variations to giving pain relief at home. METHODS: This prospective descriptive study was conducted in the ED at a tertiary care, freestanding children's hospital with a current annual census of approximately 80,000. An anonymous prospective questionnaire was given to caregivers of children between 2 and 17 years of age presenting to the ED between August 2013 and September, 2014. The study population was obtained as a convenience sample. All were self-referred with chief complaints of head, ear, or extremity pain. The questionnaire asked about pain medications and doses given at home as well as the reasons parents gave medication or refused to give pain medication before arrival. Charts were then abstracted to obtain demographic information and care received in the ED. RESULTS: A total of 154 (45.6%) of the 338 patients enrolled did not receive pain relief before coming to the ED. There were no differences in pain medication received at home based on ethnicity (P = 0.423) or age (P = 0.580). Parents could choose from a list of multiple reasons as to why pain medications were given and/or free text their own answer. The main reasons given by parents were that the accident did not happen at home (28.6%) and that they did not have time to give pain relief before coming to the ED (13%). Other common answers were "had no pain relievers at home" (12.4%) or "afraid it would be wrong/harmful/did not want to mask symptoms" (9.2%). Seventeen parents responded that their child did not complain of pain. Overall, only 28.1% of participants stated lack of pain medications at home. CONCLUSIONS: In this study, approximately half of all children receive an analgesic for their painful condition before coming to the ED. Continued education regarding pain relief before coming to the ED is needed. Future studies will focus on educating parents to provide analgesia at home.

Defining No Pain, Mild, Moderate, and Severe Pain Based on the Faces Pain Scale-Revised and Color Analog Scale in Children With Acute Pain.

OBJECTIVES: The aims of this study were to define the Faces Pain Scale-Revised (FPS-R) and Color Analog Scale (CAS) scores associated with no pain, mild pain, moderate pain, and severe pain in children with acute pain, and to identify differences based on age, sex, and ethnicity. METHODS: We conducted a prospective observational study in 2 pediatric emergency departments of children aged 4 to 17 years with painful and nonpainful conditions. We assessed their pain intensity using the FPS-R, CAS, and qualitative measures. Pain score cut points that best differentiated adjacent categories of pain were identified using a receiver operating characteristic-based method. Cut points were compared within subgroups based on age, sex, and ethnicity. RESULTS: We enrolled 620 patients, of whom 314 had painful conditions. The mean age was 9.2 years; 315 (50.8%) were in the younger age group (aged 4-7 years); 291 (46.8%) were female; and 341 (55%) were Hispanic. The scores best representing categories of pain for the FPS-R were as follows: no pain, 0 and 2; mild pain, 4; moderate pain, 6; and severe pain, 8 and 10. For the CAS, these were 0 to 1, 1.25 to 2.75, 3 to 5.75, and 6 to 10, respectively. Children with no pain frequently reported nonzero pain scores. There was considerable overlap of scores associated with mild and moderate pain. There were no clinically meaningful differences of scores representing each category of pain based on age, ethnicity, and race. CONCLUSIONS: We defined pain scores for the FPS-R and CAS associated with categories of pain intensity in children with acute pain that are generalizable across subgroups based on patient characteristics. There were minor but potentially important differences in pain scores used to delineate categories of pain intensity compared to prior convention.

Procalcitonin as a Marker of Bacteremia in Patients With Fever and Acute Lymphoblastic Leukemia.

BACKGROUND: Children undergoing treatment for acute lymphoblastic leukemia (ALL) often present to the emergency department (ED) with a fever. They are at high risk of bacteremia secondary to being immunocompromised. Recent reports indicate that procalcitonin (PCT) is a useful marker of bacteremia in children. OBJECTIVE: Our objective was to evaluate the clinical utility of PCT as a rapid marker of bacteremia in children with ALL presenting to the ED with a fever. In addition, we compared the results of PCT with white blood cell (WBC) count, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). METHODS: Retrospective chart reviews were conducted of 492 patients with a total of 735 visits presenting to the ED from January 2009 to June 2012 with fever and a history of ALL where a PCT and a blood culture (BC) were obtained,. Positive BCs determined to be contaminants were excluded. The predictive powers of PCT, WBC, ESR, and CRP for bacteremia were evaluated using the area under the receiver operating characteristic curve with 95% confidence intervals (CI). In addition, each of the 4 markers were also examined in a logistic regression model as a potential predictor of the BC result. RESULTS: A total of 735 PCT values were correlated with BC results. There were 76 (10.3%) true-positive BCs. The area under the receiver operating characteristic curve was 0.729 (95% CI, 0.661-0.792) for PCT, 0.685 (95% CI, 0.531-0.823) for ESR, 0.622 (95% CI, 0.460-0.796) for CRP, and 0.567 (95% CI, 0.483-0.649) for WBC. When logistic regression was used, the transformation log PCT was significantly associated with BC result whereas each of the other 3 markers, after appropriate transformation to remove heavy skewness, was not significant (all P > 0.1). A doubling of PCT was associated with an odds ratio of 1.32 for positive BCs (95% CI, 1.15-1.53). CONCLUSIONS: Procalcitonin value was significantly associated with positive BC (P < 0.0001). The diagnostic performance of PCT was better than the other markers of inflammation. Its use in the ED in a select population of patients may be of significant value in identifying bacteremia. This has the potential to lead to a decrease in unwarranted use of antibiotics, hospital length of stay, and health care expenditures.

Effects of Timing to Diagnosis and Appendectomy in Pediatric Appendicitis.

OBJECTIVES: Prospectively follow pediatric appendicitis patients to assess outcomes and rates of appendiceal perforations relative to duration of symptomatology and appendectomy timing. METHODS: Data were collected on the duration of symptomatology to diagnosis and from diagnosis to appendectomy. Symptomatology duration was evaluated in 24-hour increments, and diagnosis to appendectomy was evaluated in 3-hour intervals. Appendiceal perforation rates, hospital length of stay (LOS), and operating room (OR) times were evaluated. RESULTS: Data were analyzed on 230 patients. Average age was 9.3 years (±3.2), 93 (40%) were female, and 64 (28%) appendectomies were perforated. Perforations had a mean 10 minutes longer OR time (63 vs 50 minutes, P < 0.001) and a 57% increase in hospital LOS (3 days' interquartile range, 1-5 vs 1 day's interquartile range, 1-3; P < 0.001). From diagnosis to appendectomy, those taken 0 to 3 hours, 4 to 6 hours, or longer than 6 hours after diagnosis had no statistically significant difference in hospital LOS or perforation rates and no clinically significant difference in OR times. Symptomatology greater than 48 hours had hospital LOS 55.7% greater and 4.9 times increased odds for perforation than those 0 to 23 hours (P < 0.05).We found no effect on perforation rates, hospital LOS, or OR time when symptomatology duration was compared independently with timing of surgery. CONCLUSIONS: Pediatric patients with appendicitis presenting with greater than 48 hours of symptomatology had 4.9 times increased odds of perforation and 56% greater hospital LOS than those presenting within 0 to 23 hours. We were unable to demonstrate a difference in perforation rates based on emergency department LOS before surgery.

Effectiveness of standardized combination therapy for migraine treatment in the pediatric emergency department.

OBJECTIVE: To compare outcomes of pediatric migraine patients treated in an emergency department (ED) before and after implementation of a standardized combination intravenous therapy regimen aimed toward improving and standardizing abortive migraine therapy. BACKGROUND: In a pediatric ED, migraines represent 8-18% of all headache visits. Despite this large number, no standard treatment for acute migraine therapy currently exists. METHODS: The study utilized a retrospective chart review of patients seeking acute migraine treatment at a tertiary care, pediatric ED from August 2006 to March 2010. Inclusion criteria were pediatric migraine patients as defined by International Headache Society guidelines. The comparison population received various migraine therapies based on attending practice preference. After October 2008, patients received standardized intravenous combination therapy involving a normal saline fluid bolus, ketorolac, prochlorperazine, and diphenhydramine. Occasionally, metoclopramide was substituted during prochlorperazine shortages. Reduction in headache pain score was the primary outcome. Secondary outcome measures included length of ED stay, hospital admission rate, and ED readmission rate within 48 hours. RESULTS: The study yielded 87 patients who received standardized combination therapy and 165 comparison patients. No significant difference in patient characteristics existed when evaluating patient demographics, outpatient medication use, and initial headache pain score. When compared with the non-standardized therapy population, the combination therapy patients revealed significant reductions in pain score (decrease of 5.3 vs. 6.9, difference -1.6, 95% confidence interval -2.2 to -0.8, P < .001), length of ED stay (5.3 vs. 4.4 hours, difference 0.9, 95% confidence interval 0.2-1.6, P = .008), and hospital admission rate (32% vs. 3%, P < .001) without changes in ED return rate (7% vs. 2%, P = .148). CONCLUSION: Standardized combination therapy is effective for acute pediatric migraine therapy in the ED by significantly reducing headache pain scores, length of ED stay, and hospital admission rates.

Management of the child after enema-reduced intussusception: hospital or home?

BACKGROUND: Standard practice has been to admit children for an observation period after enema-reduced intussusception. However, the utility of such routine practice has not been clearly justified. STUDY OBJECTIVES: The main objective was to determine the rate and timing of recurrent intussusception after successful enema reduction and describe any associated complications. METHODS: The study was a retrospective chart review identifying children with enema-reduced intussusception during a 7-year period from 2002 through 2008. Subjects were children ages 0 to 17 years presenting to the Emergency Department (ED) of a tertiary care, free-standing children's hospital with confirmed and uncomplicated enema-reduced intussusception. RESULTS: During the study period there were 98 children with successful enema reduction of intussusception. There were 10 episodes of recurrence in 7 patients, for an overall recurrence rate of 7.1%. Three patients had two recurrences each, and the remainder had single recurrences. Two patients had early recurrences (<48 h) at 3 and 5 h, for an early recurrence rate of 2.0%. The late recurrence rate (>48 h) was 5.1%. No adverse events were noted in any of the recurrences. CONCLUSIONS: Given the low early recurrence rate for enema-reduced intussusception and the minimal risk of adverse outcomes, ED observation for a 6-h period seems to be a safe alternative to inpatient management. These results support previous work and suggest that these patients can be managed on an outpatient basis.

Needle-free jet injection of lidocaine for local anesthesia during lumbar puncture: a randomized controlled trial.

BACKGROUND: Lumbar puncture (LP) is an essential procedure in the emergency department (ED) for the evaluation of meningitis. Subcutaneous injection of lidocaine before LP for local anesthesia is not a pain-free procedure. The J-Tip device allows an intradermal needle-free jet injection of 1% buffered lidocaine. This study compares needle-free jet injection of lidocaine to saline in reducing pain before LP in infants. METHODS: This is a randomized, double-blinded, placebo-controlled trial involving infants, younger than 3 months, presenting to the ED meeting clinical criteria for LP. All patients were administered the J-Tip and randomized to either treatment with 1% buffered lidocaine or an equivalent amount of sterile normal saline before LP. Vital signs were recorded during the procedure. Facial expressions as well as crying times were video recorded from start to finish. Independent reviewers assigned pain scores based on the validated Neonatal Facial Coding System with possible scores ranging from 0 to 5. RESULTS: A total of 55 patients were enrolled. Mean (SD) pain scores at the time of needle insertion were 4.1 (1.3) for the lidocaine group and 4.8 (0.5) for the saline group (P = 0.01). Length of cry was also shorter for those in the lidocaine group, 38.5 versus 48.8 seconds (P = 0.04). Overall, κ was 0.76 between 2 independent reviewers. CONCLUSIONS: Needle-free injection of 1% buffered lidocaine administered before needle insertion for LP in infants reduces pain and length of cry, compared with normal saline.

Procalcitonin as a marker of bacteremia in children with fever and a central venous catheter presenting to the emergency department.

OBJECTIVE: To evaluate the clinical use of procalcitonin (PCT) as a rapid marker for the identification of bacteremia in the emergency department (ED) population of children with fever and a central venous catheter (CVC). METHODS: Children were identified on presentation to the ED with a chief complaint of fever and who had a CVC. Fever was defined as 38°C or higher orally. Patients were excluded from the study if they had received antibiotics within the previous 24 hours of presenting to the ED, if they had a peripherally inserted central catheter line or by parental refusal. On presentation to the ED, all patients had a complete blood cell count with differential, blood culture from the central line, and PCT levels drawn. All had empiric antibiotics initiated. Blood culture results were recorded, and in the case of positive cultures, time to positive culture was noted. RESULTS: Sixty-two patients (aged 5 months-18 y) were enrolled, and 14 (23%) had a positive culture. Mean PCT value in bacteremic patients was 18.47 ± 31.6 ng/mL and 0.65 ± 1.2 ng/mL in nonbacteremic patients (P < 0.001). Median PCT for negative blood culture was 0.23 ng/mL (interquartile range, 0.11-0.61) and 1.15 ng/mL for a positive blood culture (interquartile range, 0.45-29.16). The receiver operating characteristic analysis identified a level of PCT of 0.3 ng/mL as the best cutoff point that produced a sensitivity of 93% and a specificity of 63% (area under the curve, 0.82). CONCLUSIONS: The PCT levels are useful in identifying children with fever and a CVC who are bacteremic in the ED.

Intussusception: clinical presentations and imaging characteristics.

OBJECTIVE: The objectives of this study were to determine the prevalence of clinical findings associated with intussusception based on age and to evaluate the test characteristics of the presence of air in the ascending colon on abdominal radiographs and the effectiveness of ultrasound in diagnosing intussusception. METHODS: This was a retrospective cohort study via chart review at a tertiary care center from January 2002 to December 2008. All children, aged 0 to 17 years, were identified with intussusception by International Classification of Diseases, Ninth Revision diagnostic coding. Charts were reviewed for clinical signs and symptoms at presentation, and all diagnostic studies were retrieved. A pediatric radiologist reviewed all films and ultrasounds. RESULTS: A total of 219 patients were identified with intussusception. One hundred thirty-two (60%) of patients were male; 127 (60%) were younger than 1 year (median, 7 months), 59 (27%) were 13 to 35 months (median, 23 months), and 33 (15%) were 3 years or older (median, 5 years). Children younger than 12 months were more likely to present with emesis, irritability, and guaiac-positive or grossly bloody stools compared with children older than 12 months (P < 0.05). In children older than 12 months, abdominal pain was the most common symptom (>96%). Plain films were performed in 192 children, and of these, 163 (85%) had no air present in the ascending colon. Abdominal ultrasound was performed on 63 patients, with 58 (92%) having findings consistent with intussusception. CONCLUSIONS: Abdominal pain is the most common complaint in all ages for children presenting with intussusception. In children younger than 12 months, the strongest clinical predictors are emesis, irritability, and blood in the stool. For diagnosing intussusceptions, radiographs of the abdomen performed well, but ultrasound performed better, diagnosing intussusception in 92% of the cases.

Efficacy of racemic albuterol versus levalbuterol used as a continuous nebulization for the treatment of acute asthma exacerbations: a randomized, double-blind, clinical trial.

OBJECTIVE: To compare racemic albuterol (RAC) with levalbuterol (LEV) in continuous form for the treatment of acute pediatric asthma exacerbations in the emergency department. STUDY DESIGN: Children between the ages of 6 and 17 inclusive were enrolled if they had a history of asthma, presented to the emergency department with an acute asthma exacerbation, and had an initial forced expiratory volume in 1 second (FEV1) <70% predicted. Patients were then randomized to receive either 7.5 mg of RAC or 3.75 mg of LEV over 1 hour, in addition to standard asthma therapies. Spirometry and asthma scoring were performed at the end of the first hour, and a second hour-long nebulization with the same drug was administered if deemed necessary. Spirometry and asthma scoring were again performed and the final disposition was recorded. As a second, optional part of the study, baseline serum albuterol levels were collected on some patients before treatment. RESULTS: A total of 99 patients completed the study (44 RAC and 55 LEV). Baseline characteristics were similar except that the RAC group had a higher baseline asthma score. Children in the RAC group had a greater improvement in their FEV1 (p = .043) as well as in their asthma scores (p = .01) after 1 hour of continuous treatment compared to the LEV group. The greater improvement in asthma scores was maintained after the second hour of continuous therapy in the RAC group (p = .008) but not for FEV1 measurements (p = .57). There were no differences between groups for changes in heart rate, respiratory rate, oxygen saturation, or rates of admission. CONCLUSIONS: At the doses used, RAC appears to be superior to LEV with respect to changes in FEV1 and asthma score. There was no significant difference between the drugs with respect to admission rates or side-effect profile.

Utility of portable spirometry in a pediatric emergency department in children with acute exacerbation of asthma.

OBJECTIVES: The primary purpose of this study was to determine if portable spirometers can be successfully used in an emergency department (ED) in children with an acute exacerbation of asthma. The secondary purpose of this study was to determine if a validated clinical asthma score (CAS) correlates with the spirometry results in children with an acute exacerbation of asthma. METHODS: Children between the ages of 6 and 17 years who presented to an urban free-standing children's hospital ED with an acute exacerbation of asthma were enrolled in our study. On arrival, the CAS was recorded and then portable spirometry was performed. Attempts were continued until acceptable and reproducible flow loop measurements were obtained or until the patient was unable to perform further attempts. Outcomes included success at spirometry and correlation of spirometry with the CAS. RESULTS: A total of 101 patients were enrolled in this study. Of those patients, only 35 (35%) were able to successfully perform portable spirometry. Successful spirometry attempts were associated with older age (10.4 vs. 8.9, p = .01), lower respiratory rates (24.8 vs. 30.2, p = .001), lower heart rates (110 vs. 124, p = .004), and lower CASs (8.4 vs. 9.7, p = .001). Increasing asthma severity correlated with a decreased likelihood of successfully obtaining a useful forced expiratory volume in 1 second (FEV(1)) measurement (p = .013). Compared with cases of mild asthma, a patient with moderate asthma is 33% less likely to be able to perform spirometry, and a patient with severe asthma 93% less likely to perform spirometry. The CAS correlated poorly with the more objective measure of FEV(1)% predicted in those with mild asthma. CONCLUSION: Many children are incapable of using portable spirometry for the evaluation of acute exacerbations of asthma in the ED. The clinical asthma scoring system demonstrated poor correlation with portable spirometry measurements in terms of severity classification.

Using appendicitis scores in the pediatric ED.

STUDY OBJECTIVE: The aims of the study were to prospectively evaluate the Alvarado and Samuel (pediatric appendicitis score [PAS]) appendicitis scoring systems in children and determine performance based on sex. METHODS: Children with abdominal pain concerning for appendicitis were recruited. Nine parameters evaluated by the scores were documented before imaging/surgery consultation. Test characteristics were calculated on all patients and by sex. RESULTS: Two hundred eighty-seven patients enrolled; median age was 9.8 years; and 155 (54%) were diagnosed with pathologic examination-confirmed appendicitis. Patients with appendicitis had mean PAS of 7.6, and those without had mean of 5.6 (P < .001). Patients with appendicitis had a mean Alvarado of 7.2, and those without had a mean of 5.2 (P < .001). In appendicitis patients, PAS cutoff of 6 or greater would give 137 correct diagnoses; sensitivity, 88%; specificity, 50%; and positive predictive value (PPV), 67%. An Alvarado cutoff of 7 or greater would give 118 correct diagnoses; sensitivity, 76%; specificity, 72%; and PPV, 76%. Both performed better in males than females. CONCLUSION: Regardless of sex, neither PAS nor Alvarado has adequate predictive values for sole use to diagnose appendicitis.

Child abuse education: an objective evaluation of resident and attending physician knowledge.

OBJECTIVE: The objective of the study was to evaluate residents' and practicing physicians' medical knowledge of child abuse and maltreatment. METHODS: In a freestanding pediatric hospital and community hospital, a 30-question survey was administered to pediatric residents, general pediatricians (GPs), and pediatric emergency medicine (PEM) physicians. The institution's child protection team developed the questions, which were pilot tested for validity. Question content covered major concepts in child abuse and neglect. Information on previous training of child abuse was also collected. RESULTS: There were 95 respondents, 64.2% (n = 61) were residents, 19% (n = 18) were GPs, and 16.8% (n = 16) were PEM physicians. Overall, the average score was 63.3% (SD, 13.8%). There was a statistically significant difference in the knowledge of child abuse and neglect across physician categories (P < 0.001). Pediatric emergency medicine physicians scored the highest (76.9 [SD, 9.1]) compared with GPs (66.7 [SD, 12.4]; P = 0.018) and pediatric residents (60.4 [SD, 12.9]; P < 0.001). There was no difference in the level of knowledge across residency training years (P = 0.076). CONCLUSIONS: With a mean score in our study of 63.3%, there appears to be an overall lack of knowledge in child abuse. These findings highlight the need for increased education in child maltreatment.

Bedside ultrasound in the diagnosis of pediatric clavicle fractures.

OBJECTIVE: The objective of the study was to determine the diagnostic accuracy of pediatric emergency physicians in diagnosing clavicle fractures by bedside ultrasound (US). METHODS: This was a prospective study of pediatric emergency department (ED) patients with suspected clavicle fractures conducted in a tertiary-care, freestanding pediatric hospital. A convenience sample of patients younger than 17 years underwent bedside US for detection of clavicle fracture by pediatric emergency physicians with limited US training. Ultrasound findings were compared with standard radiographs, which were considered the criterion standard. Pain scores using the validated color analog scale (0-10) were determined before and during US. Total length of stay in the ED, time to US, and time to radiograph were recorded. RESULTS: Fifty-eight patients were enrolled, of which 39 (67%) had fracture determined by radiograph. Ultrasound interpretation gave a sensitivity of 89.7% (95% confidence interval [CI], 75.8%-97.1%) and specificity of 89.5% (95% CI, 66.9%-98.7%). Positive and negative predictive values were 94.6% (95% CI, 81.8%-99.3%) and 81.0% (95% CI, 58.1%-94.5%), respectively. Positive and negative likelihood ratios were 8.33 and 0.11, respectively. Pain scores averaged 4.7 before US and 5.2 during US (P = 0.204). There was a statistically significant difference between mean time to US (76 minutes) and mean time to radiograph (107 minutes) (P < 0.001). CONCLUSIONS: Pediatric emergency physicians with minimal formal training can accurately diagnose clavicle fractures by US. In addition, US itself is not associated with an increase in pain and may reduce length of stay in the ED.
