RESUMO
BACKGROUND: To improve our understanding of adherence to discharge medications in the ED and within research trials, we sought to quantify medication adherence and identify predictors thereof in children with acute gastroenteritis (AGE). METHODS: We conducted a secondary analysis of a randomized trial of twice daily probiotic for 5 days. The population included previously healthy children aged 3-47 months with AGE. The primary outcome was patient-reported adherence to the treatment regimen, defined a priori as having received >70% of the prescribed doses. Secondary outcomes included predictors of treatment adherence and concordance between patient-reported adherence and the returned medication sachet counts. RESULTS: After excluding participants with missing data on adherence, 760 participants were included in this analysis: 383 in the probiotic arm (50.4%); and 377 in the placebo arm (49.6%). Self-reported adherence was similar in both groups (77.0% in probiotic versus 80.3% in placebo). There was good agreement between self-reported adherence and sachet counts (87% within limits of agreement (-2.9 to 3.5 sachets) on the Bland-Altman plots). In the multivariable regression model, covariates associated with adherence were greater number of days of diarrhea post-emergency department visit, and the study site; covariates negatively associated with adherence were age 12-23 months, severe dehydration and greater total number of vomiting and diarrhea episodes after enrolment. CONCLUSIONS: Longer duration of diarrhea and study site were associated with higher probiotic adherence. Age 12-23 months, severe dehydration and greater number of vomiting and diarrhea episodes post enrolment negatively predicted treatment adherence.

OBJECTIVE: to determine diagnostic accuracy of an US-MRI clinical diagnostic pathway to detect appendicitis in the emergency department (ED). STUDY DESIGN: prospective cohort study of 624 previously healthy children 4-17 years old undergoing US for suspected appendicitis and clinical re-assessment. Children with non-diagnostic USs and persistent appendicitis concern/conclusive US-reassessment discrepancies underwent ultra-rapid MRI (US-MRI pathway), interpreted as positive, negative or non-diagnostic. Cases with missed appendicitis, negative appendectomies, and CT utilization were considered clinically diagnostically inaccurate. Primary outcome was the proportion of accurate diagnoses of appendicitis/lack thereof by the pathway. RESULTS: 150/624 (24%) children had appendicitis;255 USs (40.9%) were non-diagnostic. Of 139 US-MRI pathway children (after 117 non-diagnostic and 22 conclusive USs), 137 [98.6%; 95% CI 0.96-1.00] had clinically accurate outcomes (1 CT, 1 negative appendectomy): sensitivity 18/18 [100%], specificity 119/121 [98.3%], positive predictive value 18/20 [90.5%], negative predictive value 119/119 [100%]. MRI imaging accuracy was 134/139 (96.4%); 3 MRIs were non-diagnostic (no appendicitis). In the overall algorithm, 616/624 [98.7% (0.97-0.99)] patients had accurate outcomes: 147/150 (98.0%) appendicitis cases had confirmatory surgeries (3 CTs) and 469/474 (98.9%) appendicitis-negative children had no surgery/CT. CONCLUSION: this study demonstrated high clinical accuracy of the US-rapid-MRI pathway in suspected pediatric appendicitis after non-diagnostic US.

BACKGROUND: It is unknown if probiotics exert pathogen-specific effects in children with diarrhea secondary to acute gastroenteritis. METHODS: Analysis of patient-level data from 2 multicenter randomized, placebo controlled trials conducted in pediatric emergency departments in Canada and the United States. Participants were 3-48 months with >3 diarrheal episodes in the preceding 24 hours and were symptomatic for <72 hours and <7 days in the Canadian and US studies, respectively. Participants received either placebo or a probiotic preparation (Canada-Lactobacillus rhamnosus R0011/Lactobacillus helveticus R0052; US-L. rhamnosus GG). The primary outcome was post-intervention moderate-to-severe disease (ie, ≥9 on the Modified Vesikari Scale [MVS] score). RESULTS: Pathogens were identified in specimens from 59.3% of children (928/1565). No pathogen groups were less likely to experience an MVS score ≥9 based on treatment allocation (test for interaction = 0.35). No differences between groups were identified for adenovirus (adjusted relative risk [aRR]: 1.42; 95% confidence interval [CI]: .62, 3.23), norovirus (aRR: 0.98; 95% CI: .56, 1.74), rotavirus (aRR: 0.86; 95% CI: .43, 1.71) or bacteria (aRR: 1.19; 95% CI: .41, 3.43). At pathogen-group and among individual pathogens there were no differences in diarrhea duration or the total number of diarrheal stools between treatment groups, regardless of intervention allocation or among probiotic sub-groups. Among adenovirus-infected children, those administered the L. rhamnosus R0011/L. helveticus R0052 product experienced fewer diarrheal episodes (aRR: 0.65; 95% CI: .47, .90). CONCLUSIONS: Neither probiotic product resulted in less severe disease compared to placebo across a range of the most common etiologic pathogens. The preponderance of evidence does not support the notion that there are pathogen specific benefits associated with probiotic use in children with acute gastroenteritis. CLINICAL TRIALS REGISTRATION: NCT01773967 and NCT01853124.

OBJECTIVE: To evaluate the effects of pre- and intraprocedural opioids on adverse events in children undergoing procedural sedation with ketamine in the emergency department (ED). STUDY DESIGN: We conducted a retrospective cohort study of all children aged 0-18 years who underwent procedural sedation with intravenous ketamine alone, or in combination with an opioid, at a tertiary-care pediatric ED between June 1, 2018, and August 31, 2020. We explored predictors of serious adverse events (SAEs), desaturation or respiratory intervention, and vomiting. RESULTS: Of 1164 included children (694 male, 59.6%; median age 5.0 years [IQR 2.0-8.0]), 80 (6.8%) vomited, 63 (5.4%) had a desaturation or required respiratory interventions, and 6 (0.5%) had SAEs. Pre- and intraprocedural opioids were not independent predictors of sedation-related adverse events. A concurrent respiratory illness (aOR 3.73; 95% CI 1.31-10.60, P = .01), dental procedure (aOR 3.05; 95% CI 1.25-7.21, P = .01), and a greater total ketamine dose (aOR 1.75; 95% CI 1.21-2.54, P = .003) were independent predictors of desaturation or respiratory interventions. A greater total ketamine dose (aOR 1.86; 95% CI 1.16-2.98, P = .01) and older age (aOR 1.15; 95% CI 1.07-1.24, P < .001), were independent predictors of vomiting. CONCLUSIONS: Pre- and intraprocedural opioids do not increase the likelihood of sedation-related adverse events. SAEs are rare during pediatric procedural sedation with ketamine in the ED.

STUDY OBJECTIVE: This study aimed to explore oral ondansetron usage and impact on outcomes in clinical practice. METHODS: This observational study was a planned secondary analysis of 2 trials conducted in 10 US and 6 Canadian institutions between 2014 and 2017. Children 3 to 48 months old with gastroenteritis and ≥3 episodes of vomiting in the 24 hours preceding emergency department (ED) presentation were included. Oral ondansetron was administered at the discretion of the provider. The principal outcomes were intravenous fluid administration and hospitalization at the index visit and during the subsequent 72 hours and diarrhea and vomiting frequency during the 24 hours following the ED visit. RESULTS: In total, 794 children were included. The median age was 16.0 months (interquartile range 10.0 to 26.0), and 50.1% (398/794) received oral ondansetron. In propensity-adjusted analysis (n=528), children administered oral ondansetron were less likely to receive intravenous fluids at the index visit (adjusted odds ratio [aOR] 0.50; 95% confidence interval [CI] 0.29 to 0.88). There were no differences in the frequencies of intravenous fluid administration within the first 72 hours (aOR 0.65; 95% CI 0.39 to 1.10) or hospitalization at the index visit (aOR 0.31; 95% CI 0.09 to 1.10) or the subsequent 72 hours (aOR 0.52; 95% CI 0.21 to 1.28). Episodes of vomiting (aRR 0.86; 95% CI 0.63 to 1.19) and diarrhea (aRR 1.11; 95% CI 0.93 to 1.32) during the 24 hours following ED discharge also did not differ. CONCLUSION: Among preschool-aged children with gastroenteritis seeking ED care, oral ondansetron administration was associated with a reduction in index ED visit intravenous fluid administration; it was not associated with intravenous fluids administered within 72 hours, hospitalization, or vomiting and diarrhea in the 24 hours following discharge.

OBJECTIVES: Although most acute gastroenteritis (AGE) episodes in children rapidly self-resolve, some children go on to experience more significant and prolonged illness. We sought to develop a prognostic score to identify children at risk of experiencing moderate-to-severe disease after an index emergency department (ED) visit. METHODS: Data were collected from a cohort of children 3 to 48âmonths of age diagnosed with AGE in 16 North American pediatric EDs. Moderate-to-severe AGE was defined as a Modified Vesikari Scale (MVS) score ≥9 during the 14-day post-ED visit. A clinical prognostic model was derived using multivariable logistic regression and converted into a simple risk score. The model's accuracy was assessed for moderate-to-severe AGE and several secondary outcomes. RESULTS: After their index ED visit, 19% (336/1770) of participants developed moderate-to-severe AGE. Patient age, number of vomiting episodes, dehydration status, prior ED visits, and intravenous rehydration were associated with MVS ≥9 in multivariable regression. Calibration of the prognostic model was strong with a P value of 0.77 by the Hosmer-Lemenshow goodness-of-fit test, and discrimination was moderate with an area under the receiver operator characteristic curve of 0.68 (95% confidence interval [CI] 0.65-0.72). Similarly, the model was shown to have good calibration when fit to the secondary outcomes of subsequent ED revisit, intravenous rehydration, or hospitalization within 72âhours after the index visit. CONCLUSIONS: After external validation, this new risk score may provide clinicians with accurate prognostic insight into the likely disease course of children with AGE, informing disposition decisions, anticipatory guidance, and follow-up care.

BACKGROUND: Gastroenteritis accounts for approximately 1.7 million visits to the emergency department (ED) by children in the United States every year. Data to determine whether the use of probiotics improves outcomes in these children are lacking. METHODS: We conducted a randomized, double-blind trial involving 886 children 3 to 48 months of age with gastroenteritis who presented to six pediatric EDs in Canada. Participants received a 5-day course of a combination probiotic product containing Lactobacillus rhamnosus R0011 and L. helveticus R0052, at a dose of 4.0×109 colony-forming units twice daily or placebo. The primary outcome was moderate-to-severe gastroenteritis, which was defined according to a post-enrollment modified Vesikari scale symptom score of 9 or higher (scores range from 0 to 20, with higher scores indicating more severe disease). Secondary outcomes included the duration of diarrhea and vomiting, the percentage of children who had unscheduled physician visits, and the presence or absence of adverse events. RESULTS: Moderate-to-severe gastroenteritis within 14 days after enrollment occurred in 108 of 414 participants (26.1%) who were assigned to probiotics and 102 of 413 participants (24.7%) who were assigned to placebo (odds ratio, 1.06; 95% confidence interval [CI], 0.77 to 1.46; P=0.72). After adjustment for trial site, age, detection of rotavirus in stool, and frequency of diarrhea and vomiting before enrollment, trial-group assignment did not predict moderate-to-severe gastroenteritis (odds ratio, 1.06; 95% CI, 0.76 to 1.49; P=0.74). There were no significant differences between the probiotic group and the placebo group in the median duration of diarrhea (52.5 hours [interquartile range, 18.3 to 95.8] and 55.5 hours [interquartile range, 20.2 to 102.3], respectively; P=0.31) or vomiting (17.7 hours [interquartile range, 0 to 58.6] and 18.7 hours [interquartile range, 0 to 51.6], P=0.18), the percentages of participants with unscheduled visits to a health care provider (30.2% and 26.6%; odds ratio, 1.19; 95% CI, 0.87 to 1.62; P=0.27), and the percentage of participants who reported an adverse event (34.8% and 38.7%; odds ratio, 0.83; 95% CI, 0.62 to 1.11; P=0.21). CONCLUSIONS: In children who presented to the emergency department with gastroenteritis, twice-daily administration of a combined L. rhamnosus-L. helveticus probiotic did not prevent the development of moderate-to-severe gastroenteritis within 14 days after enrollment.

INTRODUCTION: It is unclear whether the alleged efficacy of probiotics in childhood acute gastroenteritis depends on the duration and severity of symptoms before treatment. METHODS: Preplanned secondary analysis of 2 randomized placebo-controlled trials in children 3-48 months of age was conducted in 16 emergency departments in North America evaluating the efficacy of 2 probiotic products (Lactobacillus rhamnosus GG and a combination probiotic: L. rhamnosus and L. helveticus). Participants were categorized in severity groups according to the duration (<24, 24-<72, and ≥72 hours) and the frequency of diarrhea episodes in the 24 hours (≤3, 4-5, and ≥6) before presentation. We used regression models to assess the interaction between pretreatment diarrhea severity groups and treatment arm (probiotic or placebo) in the presence of moderate-to-severe gastroenteritis (Modified Vesikari Scale score ≥9). Secondary outcomes included diarrhea frequency and duration, unscheduled healthcare provider visits, and hospitalization. RESULTS: A total of 1,770 children were included, and 882 (50%) received a probiotic. The development of moderate-to-severe gastroenteritis symptoms after the initiation of treatment did not differ between groups (probiotic-18.4% [162/882] vs placebo-18.3% [162/888]; risk ratio 1.00; 95% confidence interval 0.87, 1.16; P = 0.95). There was no evidence of interaction between baseline severity and treatment (P = 0.61) for the primary or any of the secondary outcomes: diarrhea duration (P = 0.88), maximum diarrheal episodes in a 24-hour period (P = 0.87), unscheduled healthcare visits (P = 0.21), and hospitalization (P = 0.87). DISCUSSION: In children 3-48 months with acute gastroenteritis, the lack of effect of probiotics is not explained by the duration of symptoms or frequency of diarrheal episodes before presentation.

OBJECTIVES: The aim of this study was to quantify the effect of the COVID-19 pandemic on pediatric emergency department (ED) utilization and outcomes. METHODS: This study is an interrupted-time-series observational study of children presenting to 11 Canadian tertiary-care pediatric EDs. Data were grouped into weeks in 3 study periods: prepandemic (January 1, 2018-January 27, 2020), peripandemic (January 28, 2020-March 10, 2020), and early pandemic (March 11, 2020-April 30, 2020). These periods were compared with the same time intervals in the 2 preceding calendar years. Primary outcomes were number of ED visits per week. The secondary outcomes were triage acuity, hospitalization, intensive care unit (ICU) admission, mortality, length of hospital stay, ED revisits, and visits for trauma and mental health concerns. RESULTS: There were 577,807 ED visits (median age, 4.5 years; 52.9% male). Relative to the prepandemic period, there was a reduction [-58%; 95% confidence interval (CI), -63% to -51%] in the number of ED visits during the early-pandemic period, with concomitant higher acuity. There was a concurrent increase in the proportion of ward [odds ratio (OR), 1.39; 95% CI, 1.32-1.45] and intensive care unit (OR, 1.20; 95% CI, 1.01-1.42) admissions, and trauma-related ED visits among children less than 10 years (OR, 1.51; 95% CI, 1.45-1.56). Mental health-related visits in children declined in the early-pandemic period (in <10 years, -60%; 95% CI, -67% to -51%; in children ≥10 years: -56%; 95% CI, -63% to -47%) relative to the pre-COVID-19 period. There were no differences in mortality or length of stay; however, ED revisits within 72 hours were reduced during the early-pandemic period (percent change: -55%; 95% CI, -61% to -49%; P < 0.001). CONCLUSIONS: After the declaration of the COVID-19 pandemic, dramatic reductions in pediatric ED visits occurred across Canada. Children seeking ED care were sicker, and there was an increase in trauma-related visits among children more than 10 years of age, whereas mental health visits declined during the early-pandemic period. When faced with a future pandemic, public health officials must consider the impact of the illness and the measures implemented on children's health and acute care needs.

OBJECTIVES: A previous randomized controlled trial showed that artificially elevating the pulse oximetry display resulted in fewer hospitalizations with no worse outcomes. This suggests that management decisions based mainly on pulse oximetry may unnecessarily increase health care costs. This study assessed the incremental cost of altered relative to true oximetry in infants with mild to moderate bronchiolitis. METHODS: A cost analysis was undertaken from the health care system and societal perspectives using patient-level data from the randomized controlled trial, with a 5-day time horizon after emergency department visit. Infants aged 4 weeks to 12 months with mild to moderate bronchiolitis were randomized to pulse oximetry measurements with true or altered saturation values displayed by artificially increasing saturation 3% points above true values. Direct and indirect health care costs were measured. Sensitivity analyses were performed to assess parameter uncertainty. RESULTS: From the health care system perspective, the average cost per patient was Can $1155 for altered oximetry and $1967 for true oximetry, with a net savings of $812. From a societal perspective, the average cost per patient was $1559 for altered oximetry and $2473 for true oximetry, with a net savings of $914. Probabilistic analyses demonstrated that altered oximetry remained the less costly study group, with an average savings of $810 (95% confidence interval, $748-$872) from the health care system perspective and $910 (95% confidence interval, $848-$973) from the societal system perspective. CONCLUSIONS: Reliance on oximetry as a major determinant in the decision to hospitalize infants with mild to moderate bronchiolitis is associated with significantly greater costs.

Importance: While intravenous magnesium decreases hospitalizations in refractory pediatric acute asthma, it is variably used because of invasiveness and safety concerns. The benefit of nebulized magnesium to prevent hospitalization is unknown. Objective: To evaluate the effectiveness of nebulized magnesium in children with acute asthma remaining in moderate or severe respiratory distress after initial therapy. Design, Setting, and Participants: A randomized double-blind parallel-group clinical trial from September 26, 2011, to November 19, 2019, in 7 tertiary-care pediatric emergency departments in Canada. The participants were otherwise healthy children aged 2 to 17 years with moderate to severe asthma defined by a Pediatric Respiratory Assessment Measure (PRAM) score of 5 or greater (on a 12-point scale) after a 1-hour treatment with an oral corticosteroid and 3 inhaled albuterol and ipratropium treatments. Of 5846 screened patients, 4332 were excluded for criteria, 273 declined participation, 423 otherwise excluded, 818 randomized, and 816 analyzed. Interventions: Participants were randomized to 3 nebulized albuterol treatments with either magnesium sulfate (n = 410) or 5.5% saline placebo (n = 408). Main Outcomes and Measures: The primary outcome was hospitalization for asthma within 24 hours. Secondary outcomes included PRAM score; respiratory rate; oxygen saturation at 60, 120, 180, and 240 minutes; blood pressure at 20, 40, 60, 120, 180, and 240 minutes; and albuterol treatments within 240 minutes. Results: Among 818 randomized patients (median age, 5 years; 63% males), 816 completed the trial (409 received magnesium; 407, placebo). A total of 178 of the 409 children who received magnesium (43.5%) were hospitalized vs 194 of the 407 who received placebo (47.7%) (difference, -4.2%; absolute risk difference 95% [exact] CI, -11% to 2.8%]; P = .26). There were no significant between-group differences in changes from baseline to 240 minutes in PRAM score (difference of changes, 0.14 points [95% CI, -0.23 to 0.50]; P = .46); respiratory rate (0.17 breaths/min [95% CI, -1.32 to 1.67]; P = .82); oxygen saturation (-0.04% [95% CI, -0.53% to 0.46%]; P = .88); systolic blood pressure (0.78 mm Hg [95% CI, -1.48 to 3.03]; P = .50); or mean number of additional albuterol treatments (magnesium: 1.49, placebo: 1.59; risk ratio, 0.94 [95% CI, 0.79 to 1.11]; P = .47). Nausea/vomiting or sore throat/nose occurred in 17 of the 409 children who received magnesium (4%) and 5 of the 407 who received placebo (1%). Conclusions and Relevance: Among children with refractory acute asthma in the emergency department, nebulized magnesium with albuterol, compared with placebo with albuterol, did not significantly decrease the hospitalization rate for asthma within 24 hours. The findings do not support use of nebulized magnesium with albuterol among children with refractory acute asthma. Trial Registration: ClinicalTrials.gov Identifier: NCT01429415.

OBJECTIVES: To examine the association of the base deficit, international normalized ratio, and Glasgow Coma Scale (BIG) score on emergency department arrival with functional dependence at hospital discharge (Pediatric Cerebral Performance Category ≥ 4) in pediatric multiple trauma patients with traumatic brain injury. DESIGN: A retrospective cohort study of a pediatric trauma database from 2001 to 2018. SETTING: Level 1 trauma program at a university-affiliated pediatric institution. PATIENTS: Two to 17 years old children sustaining major blunt trauma including a traumatic brain injury and meeting trauma team activation criteria. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Two investigators, blinded to the BIG score, determined discharge Pediatric Cerebral Performance Category scores. The BIG score was measured on emergency department arrival. The 609 study patients were 9.7 ± 4.4 years old with a median Injury Severity Score 22 (interquartile range, 12). One-hundred seventy-one of 609 (28%) had Pediatric Cerebral Performance Category greater than or equal to 4 (primary outcome). The BIG constituted a multivariable predictor of Pediatric Cerebral Performance Category greater than or equal to 4 (odds ratio, 2.39; 95% CI, 1.81-3.15) after adjustment for neurosurgery requirement (odds ratio, 2.83; 95% CI, 1.69-4.74), pupils fixed and dilated (odds ratio, 3.1; 95% CI, 1.49-6.38), and intubation at the scene or referral hospital (odds ratio, 2.82; 95% CI, 1.35-5.87) and other postulated predictors of poor outcome. The area under the BIG receiver operating characteristic curve was 0.87 (0.84-0.90). Using an optimal BIG cutoff less than or equal to 8, sensitivity and negative predictive value for functional dependence at discharge were 93% and 96%, respectively, compared with a sensitivity of 79% and negative predictive value of 91% with Glasgow Coma Scale less than or equal to 8. In children with Glasgow Coma Scale 3, the BIG score was associated with brain death (odds ratio, 2.13; 95% CI, 1.58-2.36). The BIG also predicted disposition to inpatient rehabilitation (odds ratio, 2.26; 95% CI, 2.17-2.35). CONCLUSIONS: The BIG score is a simple, rapidly obtainable severity of illness score that constitutes an independent predictor of functional dependence at hospital discharge in pediatric trauma patients with traumatic brain injury. The BIG score may benefit Trauma and Neurocritical care programs in identifying ideal candidates for traumatic brain injury trials within the therapeutic window of treatment.

BACKGROUND: Serious bacterial infections in young infants with bronchiolitis are rare. Febrile infants <1 month old with bronchiolitis often receive a lumbar puncture (LP), despite limited data for this practice and lack of clinical practice guidelines for this population. The primary objective was to investigate practice patterns in performance of LPs in the ED management of febrile infants aged ≤30 days with bronchiolitis. METHODS: A cross-sectional survey of two national paediatric emergency research networks (PediatricEmergency Research Canada (PERC) and the PediatricEmergency Research UK/Ireland (PERUKI)) was conducted January to November 2017 using a modified Dillman technique. The survey was preceded by a clinical vignette describing a well appearing, 21-day-old infant with low-grade fever, respiratory findings typical of bronchiolitis and no perinatal serious bacterial infection (SBI) risk features. RESULTS: The response rate from PERC was 169/250 (68%) and 172/201 (86%) from PERUKI. Nine physicians in training were excluded, leaving 332 eligible participants. Although most physicians believe that neonates with bronchiolitis rarely have meningitis (PERC 141/161 (87.6%); PERUKI 154/171 (90%)) and feel comfortable diagnosing bronchiolitis in this group (PERC 136/161 (84.5%); PERUKI 143/171 (83.6%)), there was significant variation in the proportion who would be likely/very likely to perform an LP (PERC 100/161 (62.1%); PERUKI 15/171 (8.8%)) (p<0.0001). Practice in Canada, <10 years in practice and lack of comfort with diagnosing bronchiolitis represent multivariable predictors of LP; OR 23.7 (95% CI 11.7 to 47.9), 2.3 (95% CI 1.2 to 4.2) and 2.5 (95% CI 1.1 to 5.0), respectively. Rapid knowledge of respiratory syncytial virus positivity would decrease LP probability from 35.4% to 20.2%. CONCLUSION: Estimated probability of performing LPs and other interventions in otherwise healthy febrile neonates with bronchiolitis is highly variable between emergency physicians in Canada and the UK/Ireland. Network, <10 years in ED practice and comfort level with diagnosing bronchiolitis in newborns constitute independent predictors of the likelihood of LP performance.

OBJECTIVES: Previous pediatric trauma studies focused on predictors of abnormal chest radiographs or included patients with low injury severity. This study identified predictors of thoracic injury (TI) diagnoses in a high-risk population and determined TI rate without predictors. METHODS: This study was a retrospective trauma registry analysis of previously healthy children aged 0 to 17 years with multisystem blunt trauma requiring trauma team activation and chest radiography who were divided into those with and without TI. Plausible TI predictors included Glasgow Coma Scale score of 13 or less, abnormal thoracic symptoms/signs, abnormal chest auscultation, respiratory distress/ rate higher than the 95th percentile, oxygen saturation less than 95%, abnormal abdominal signs/symptoms, tachycardia higher than the 95th percentile, blood pressure lower than the 5th percentile, and femur fracture. RESULTS: One hundred forty-one (29%) of 493 eligible patients had TI. Independent TI predictors include thoracic symptoms/signs (odds ratio [OR], 6.0; 95% confidence interval [CI], 3.6-10.1), abnormal chest auscultation (OR, 3.5; 95% CI, 2.0-6.2), saturation less than 95% (OR, 3.1; 95% CI, 1.8-5.5), blood pressure lower than the 5th percentile (OR, 3.7; 95% CI, 1.1-12.2), and femur fracture (OR, 2.5; 95% CI, 1.2-5.4). Six (5%) of 119 children (95% CI, 0.01-0.09) without predictors had TI. CONCLUSIONS: Predictors of TI include thoracic symptoms/signs, abnormal chest auscultation, saturation less than 95%, blood pressure lower than the 5th percentile, and femur fracture. Because an important portion of children without predictors had TI, chest radiography should remain part of pediatric trauma resuscitation.

OBJECTIVES: To determine parental preferences for diagnostic imaging tests (DITs) for paediatric appendicitis, to rank the attributes impacting the DIT selection and to identify DIT attributes that would cause parents to switch their DIT. METHODS: Parents of children who had an abdominal ultrasound (US) for right lower quadrant pain were interviewed. Two DITs were compared at a time, parents were asked to indicate their preferred test and to rank its attributes according to the impact each attribute had on their selection. The strength of their preference for the chosen DIT was measured by systematically adjusting attributes of the chosen DIT until the parent changed their choice. RESULTS: Fifty parents were interviewed. For US versus CT, more parents preferred US (68%, P=0.02) with higher importance ranks for cancer risk (P<0.0001), test accuracy (P=0.04), pain during test (P=0.3), and scan length (P<0.0001); and lower ranks for sedation (P=0.02), intravenous (IV) (P<0.02), and oral contrast (P=0.06). For US versus MRI, parents preferred MRI (78%, P<0.0001) with higher importance ranks for accuracy (P=0.2), pain during test (P=0.06), and scan length (P=0.06); and lower for noise (P<0.0001), claustrophobia (P<0.0001), use of IV contrast (P=0.06), and sedation (P=0.2). CONCLUSION: US and MRI were the DIT preferred by parents for the investigation of acute paediatric appendicitis.
RESUMO
Purpose To evaluate the sensitivity, specificity, and diagnostic odds ratios of US, CT, and MRI as second-line imaging modalities after initial US for assessing acute appendicitis in children and adults. Materials and Methods A literature search was conducted in Medline and Embase to identify articles that used surgery or histopathologic examination alone or in combination with clinical follow-up or chart review to evaluate the diagnostic accuracy of second-line imaging modalities. The quality of articles was assessed by using the Quality Assessment of Diagnostic Accuracy Studies-2 and the Standards for Reporting of Diagnostic Accuracy tools. Results For studies of children, the number of studies and patients were as follows: US, six studies and 548 patients; CT, nine studies and 1498 patients; MRI, five studies and 287 patients. For studies of adults, the number of studies and patients were as follows: US, three studies and 169 patients; CT, 11 studies and 1027 patients; MRI, six studies and 427 patients. Pooled sensitivities and specificities of second-line US for diagnosis of appendicitis in children were 91.3% (95% confidence interval [CI]: 83.8%, 95.5%) and 95.2% (95% CI: 91.8%, 97.3%), respectively; and in adults, the pooled sensitivities and specificities were 83.1% (95% CI: 70.3%, 91.1%) and 90.9% (95% CI: 59.3%, 98.6%), respectively. Regarding second-line CT in children, the pooled sensitivities and specificities were 96.2% (95% CI: 93.2%, 97.8%) and 94.6% (95% CI: 92.8%, 95.9%); and in adults, the pooled sensitivities and specificities were 89.9% (95% CI: 85.4%, 93.2%) and 93.6% (95% CI: 91.2%, 95.3%), respectively. Regarding second-line MRI in children, pooled sensitivities and specificities were 97.4% (95% CI: 85.8%, 100%) and 97.1% (95% CI: 92.1%, 99.0%); and in adults, the pooled sensitivities and specificities were 89.9% (95% CI: 84.8%, 93.5%) and 93.6% (95% CI: 90.9%, 95.5%), respectively. Conclusion Second-line US, CT, and MRI have comparable and high accuracy in helping to diagnose appendicitis in children and adults, including pregnant women. All three modalities may be valid as second-line imaging in a clinical imaging pathway for diagnosis and management of appendicitis.

OBJECTIVES: To identify the epidemiologic predictors and stratify the risk of critical care unit (CCU) admission or death in bronchiolitis following emergency department discharge. This information has not yet been explored. STUDY DESIGN: A population-based cohort study using Ontario-wide demographic and healthcare databases linked at the individual level. We assessed all infants with bronchiolitis discharged home from all emergency departments in Ontario, Canada, 2003-2014. Targeted information included plausible demographic and clinical predictors of CCU admission/death within 14 days of emergency department discharge. Using multivariable logistic regression analyses, we identified independent predictors of this outcome and stratified the outcome risk by the type of multivariable predictor. RESULTS: Of 34 270 study infants, 102 (0.3%) were admitted to CCU or died after discharge. Predictors of CCU admission/death were: comorbidities (OR 5.33; 95% CI 2.82-10.10), younger age [months] (OR 1.47; 95%CI 1.33-1.61), low income (OR 1.53; 95% CI 1.01-2.34), younger gestational age [weeks] (OR 1.14; 95%CI 1.06-1.22), and emergent presentation (Canadian Triage and Acuity Scale 2) at the index visit (OR 1.55, 95% CI 1.03-2.33). The absolute event risk of CCU admission/death in infants with versus without comorbidities were 1.5% versus 0.26%, respectively (P < .001). The odds of these outcomes in infants with comorbidities plus ≥2 other predictors were 25 times higher than in infants without predictors (OR 25.1, 95% CI 11.4-55.3). CONCLUSIONS: Infants with comorbidities plus other predictors discharged from the emergency department with bronchiolitis are at considerable risk of subsequent CCU admission and death. These risk factors should augment current clinical and social considerations determining patient disposition.

IMPORTANCE: Gastroenteritis is a common pediatric illness. Electrolyte maintenance solution is recommended to treat and prevent dehydration. Its advantage in minimally dehydrated children is unproven. OBJECTIVE: To determine if oral hydration with dilute apple juice/preferred fluids is noninferior to electrolyte maintenance solution in children with mild gastroenteritis. DESIGN, SETTING, AND PARTICIPANTS: Randomized, single-blind noninferiority trial conducted between the months of October and April during the years 2010 to 2015 in a tertiary care pediatric emergency department in Toronto, Ontario, Canada. Study participants were children aged 6 to 60 months with gastroenteritis and minimal dehydration. INTERVENTIONS: Participants were randomly assigned to receive color-matched half-strength apple juice/preferred fluids (n=323) or apple-flavored electrolyte maintenance solution (n=324). Oral rehydration therapy followed institutional protocols. After discharge, the half-strength apple juice/preferred fluids group was administered fluids as desired; the electrolyte maintenance solution group replaced losses with electrolyte maintenance solution. MAIN OUTCOMES AND MEASURES: The primary outcome was a composite of treatment failure defined by any of the following occurring within 7 days of enrollment: intravenous rehydration, hospitalization, subsequent unscheduled physician encounter, protracted symptoms, crossover, and 3% or more weight loss or significant dehydration at in-person follow-up. Secondary outcomes included intravenous rehydration, hospitalization, and frequency of diarrhea and vomiting. The noninferiority margin was defined as a difference between groups of 7.5% for the primary outcome and was assessed with a 1-sided α=.025. If noninferiority was established, a 1-sided test for superiority was conducted. RESULTS: Among 647 randomized children (mean age, 28.3 months; 331 boys [51.1%]; 441 (68.2%) without evidence of dehydration), 644 (99.5%) completed follow-up. Children who were administered dilute apple juice experienced treatment failure less often than those given electrolyte maintenance solution (16.7% vs 25.0%; difference, -8.3%; 97.5% CI, -∞ to -2.0%; P < .001 for inferiority and P = .006 for superiority). Fewer children administered apple juice/preferred fluids received intravenous rehydration (2.5% vs 9.0%; difference, -6.5%; 99% CI, -11.6% to -1.8%). Hospitalization rates and diarrhea and vomiting frequency were not significantly different between groups. CONCLUSIONS AND RELEVANCE: Among children with mild gastroenteritis and minimal dehydration, initial oral hydration with dilute apple juice followed by their preferred fluids, compared with electrolyte maintenance solution, resulted in fewer treatment failures. In many high-income countries, the use of dilute apple juice and preferred fluids as desired may be an appropriate alternative to electrolyte maintenance fluids in children with mild gastroenteritis and minimal dehydration.
