Identifying high cognitive load activities during simulated pediatric cardiac arrest using functional near-infrared spectroscopy.

Aim: To identify specific activities associated with high cognitive load during simulated pediatric out-of-hospital cardiac arrest (POHCA) resuscitation using physiological monitoring with functional near-infrared spectroscopy (fNIRS). Methods: We recruited teams of emergency medical services (EMS) responders from fire departments located throughout the Portland, OR metropolitan area to participate in POHCA simulations. Teams consisted of both paramedics and emergency medical technicians (EMTs), with one paramedic serving as the person in charge (PIC). The PIC was outfitted with the OctaMon to collect fNIRS signals from the prefrontal cortex. Signals reported changes in oxygenated and deoxygenated hemoglobin concentrations, which were used to determine moments of increased cognitive activity. Increased cognitive activity was determined by significant increases in oxygenated hemoglobin and decreases in deoxygenated hemoglobin. Significant changes in fNIRS signals were associated with specific concurrent clinical tasks recorded by two independent researchers using video review. Results: We recorded cognitive activity of EMS providers in 18 POHCA simulations. We found that a proportion of PIC's experienced relatively high cognitive load during medication administration, defibrillation, and rhythm checks compared to other events. Conclusion: EMS providers commonly experienced increased cognitive activity during key resuscitation tasks that were related to safely coordinating team members around calculating and administering medications, defibrillation, and rhythm and pulse checks. Understanding more about activities that require high cognitive demand can inform future interventions that reduce cognitive load.

Prevalence of Bacterial Meningitis Among Febrile Infants Aged 29-60 Days With Positive Urinalysis Results: A Systematic Review and Meta-analysis.

Importance: Fever in the first months of life remains one of the most common pediatric problems. Urinary tract infections are the most frequent serious bacterial infections in this population. All published guidelines and quality initiatives for febrile young infants recommend lumbar puncture (LP) and cerebrospinal fluid (CSF) testing on the basis of a positive urinalysis result to exclude bacterial meningitis as a cause. For well infants older than 28 days with an abnormal urinalysis result, LP remains controversial. Objective: To assess the prevalence of bacterial meningitis among febrile infants 29 to 60 days of age with a positive urinalysis result to evaluate whether LP is routinely required. Data Sources: MEDLINE and Embase were searched for articles published from January 1, 2000, to July 25, 2018, with deliberate limitation to recent studies. Before analysis, the search was repeated (October 6, 2019) to ensure that new studies were included. Study Selection: Studies that reported on healthy, full-term, well-appearing febrile infants 29 to 60 days of age for whom patient-level data could be ascertained for urinalysis results and meningitis status were included. Data Extraction and Synthesis: Data were extracted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines and used the Newcastle-Ottawa Scale to assess bias. Pooled prevalences and odds ratios (ORs) were estimated using random-effect models. Main Outcomes and Measures: The primary outcome was the prevalence of culture-proven bacterial meningitis among infants with positive urinalysis results. The secondary outcome was the prevalence of bacterial meningitis, defined by CSF testing or suggestive history at clinical follow-up. Results: The parent search yielded 3227 records; 48 studies were included (17 distinct data sets of 25 374 infants). The prevalence of culture-proven meningitis was 0.44% (95% CI, 0.25%-0.78%) among 2703 infants with positive urinalysis results compared with 0.50% (95% CI, 0.33%-0.76%) among 10 032 infants with negative urinalysis results (OR, 0.74; 95% CI, 0.39-1.38). The prevalence of bacterial meningitis was 0.25% (95% CI, 0.14%-0.45%) among 4737 infants with meningitis status ascertained by CSF testing or clinical follow-up and 0.28% (95% CI, 0.21%-0.36%) among 20 637 infants with positive and negative urinalysis results (OR, 0.89; 95% CI, 0.48-1.68). Conclusions and Relevance: In this systematic review and meta-analysis, the prevalence of bacterial meningitis in well-appearing febrile infants 29 to 60 days of age with positive urinalysis results ranged from 0.25% to 0.44% and was not higher than that in infants with negative urinalysis results. These results suggest that for these infants, the decision to use LP should not be guided by urinalysis results alone.

Predicting Adverse Outcomes for Shiga Toxin-Producing Escherichia coli Infections in Emergency Departments.

OBJECTIVE: To assess the performance of a hemolytic uremic syndrome (HUS) severity score among children with Shiga toxin-producing Escherichia coli (STEC) infections and HUS by stratifying them according to their risk of adverse events. The score has not been previously evaluated in a North American acute care setting. STUDY DESIGN: We reviewed medical records of children <18 years old infected with STEC and treated in 1 of 38 participating emergency departments in North America between 2011 and 2015. The HUS severity score (hemoglobin [g/dL] plus 2-times serum creatinine [mg/dL]) was calculated using first available laboratory results. Children with scores >13 were designated as high-risk. We assessed score performance to predict severe adverse events (ie, dialysis, neurologic complication, respiratory failure, and death) using discrimination and net benefit (ie, threshold probability), with subgroup analyses by age and day-of-illness. RESULTS: A total of 167 children had HUS, of whom 92.8% (155/167) had relevant data to calculate the score; 60.6% (94/155) experienced a severe adverse event. Discrimination was acceptable overall (area under the curve 0.71, 95% CI 0.63-0.79) and better among children <5 years old (area under the curve 0.77, 95% CI 0.68-0.87). For children <5 years, greatest net benefit was achieved for a threshold probability >26%. CONCLUSIONS: The HUS severity score was able to discriminate between high- and low-risk children <5 years old with STEC-associated HUS at a statistically acceptable level; however, it did not appear to provide clinical benefit at a meaningful risk threshold.

Assessing appropriateness of pediatric emergency department visits: is it even possible?

OBJECTIVES: Numerous studies reported on the frequency of, and factors associated with inappropriate or unnecessary emergency department (ED) visits using clinician judgment as the gold standard of appropriateness. This study evaluated the reliability of clinician judgment for assessing appropriateness of pediatric ED visit. METHODS: We conducted a retrospective cohort study comparing 3 clinicians' determination of ED visit appropriateness with and without guidance from a three-question structured algorithm. We used a cohort of scheduled ED return visits deemed appropriate by the index treating clinician between May 1, 2012, and April 30, 2013. We measured the level of agreement among three clinician investigators with and without use of the structured algorithm. RESULTS: A total of 207 scheduled ED return visits were reviewed by the primary clinician reviewer who agreed with the index treating clinician for 79/207 visits (38.2%). Among a random subset of 90 return visits reviewed by all three clinicians, agreement was 67% with a Fleiss' Kappa of 0.30 (0.17-0.44). Using a three-question algorithm based on objective criteria, agreement with the index treating provider increased to 115/207 (55.6%). CONCLUSIONS: Although an important contributor to pediatric ED overcrowding, unnecessary or inappropriate visits are difficult to identify. We demonstrated poor reliability of clinician judgment to determine appropriateness of ED return visits, likely due to variability in clinical decision-making and risk-tolerance, social and systems factors impacting access and use of health care. We recommend that future studies evaluating the appropriateness of ED use standardized, objective criteria rather than clinician judgment alone.

Effectiveness of Emergency Department Treatment of Pediatric Headache and Relation to Rebound Headache.

OBJECTIVE: This study aimed to assess the association between the degree of headache relief obtained in the pediatric emergency department (PED) with abortive treatment and unscheduled return visits to the PED for a recurrent or persistent headache within 72 hours. METHODS: This was a retrospective observational study with 369 patients, all younger than 18 years, who presented to the PED with a primary complaint of either a headache or migraine. Patient and visit details were collected from the medical chart, along with presenting and discharge pain score. Percent pain reduction at discharge was determined through the following calculation: (Presenting Pain Score - Discharge Pain Score)/Presenting Pain Score. Associations were assessed using multivariable logistic regression. RESULTS: No significant association was found between the percent pain reduction and return to the PED (P = 0.49). Mean presenting pain score at the index visit was statistically higher for those who ended up returning to the PED versus those who did not (8.1 vs 7.4; P = 0.02). A trend toward increase in return visits was seen among patients who had a headache duration greater than 3 days (odds ratio, 1.99) and patients who experienced less than 50% pain reduction in the PED (odds ratio, 1.77). CONCLUSIONS: Complete resolution in the PED may not be necessary, given the lack of association between the degree of pain relief and revisit rates. Perhaps, the goal should be to achieve at least 50% pain reduction before discharge.

Predicting Hemolytic Uremic Syndrome and Renal Replacement Therapy in Shiga Toxin-producing Escherichia coli-infected Children.

BACKGROUND: Shiga toxin-producing Escherichia coli (STEC) infections are leading causes of pediatric acute renal failure. Identifying hemolytic uremic syndrome (HUS) risk factors is needed to guide care. METHODS: We conducted a multicenter, historical cohort study to identify features associated with development of HUS (primary outcome) and need for renal replacement therapy (RRT) (secondary outcome) in STEC-infected children without HUS at initial presentation. Children aged <18 years who submitted STEC-positive specimens between January 2011 and December 2015 at a participating study institution were eligible. RESULTS: Of 927 STEC-infected children, 41 (4.4%) had HUS at presentation; of the remaining 886, 126 (14.2%) developed HUS. Predictors (all shown as odds ratio [OR] with 95% confidence interval [CI]) of HUS included younger age (0.77 [.69-.85] per year), leukocyte count ≥13.0 × 103/µL (2.54 [1.42-4.54]), higher hematocrit (1.83 [1.21-2.77] per 5% increase) and serum creatinine (10.82 [1.49-78.69] per 1 mg/dL increase), platelet count <250 × 103/µL (1.92 [1.02-3.60]), lower serum sodium (1.12 [1.02-1.23 per 1 mmol/L decrease), and intravenous fluid administration initiated ≥4 days following diarrhea onset (2.50 [1.14-5.46]). A longer interval from diarrhea onset to index visit was associated with reduced HUS risk (OR, 0.70 [95% CI, .54-.90]). RRT predictors (all shown as OR [95% CI]) included female sex (2.27 [1.14-4.50]), younger age (0.83 [.74-.92] per year), lower serum sodium (1.15 [1.04-1.27] per mmol/L decrease), higher leukocyte count ≥13.0 × 103/µL (2.35 [1.17-4.72]) and creatinine (7.75 [1.20-50.16] per 1 mg/dL increase) concentrations, and initial intravenous fluid administration ≥4 days following diarrhea onset (2.71 [1.18-6.21]). CONCLUSIONS: The complex nature of STEC infection renders predicting its course a challenge. Risk factors we identified highlight the importance of avoiding dehydration and performing close clinical and laboratory monitoring.

Management practice-related and modifiable factors associated with paediatric emergency return visits.

OBJECTIVES: We explored practice-related factors associated with preventable unscheduled return visits to an emergency department (RTED). METHODS: We conducted a retrospective cohort study, using standardized review of health records. We included all visits with at least one RTED within 7 days of the index visit. Cases were reviewed by investigators and clinicians to identify: 1) the proportion of unscheduled RTED, 2) the proportion deemed clinically unnecessary and 3) the contribution of clinical practice pattern and system factors. RESULTS: There were 2809 (7.3%) index visits associated with at least one RTED. Of these, 1983 (70.6%) were unscheduled, 784 (39.5%) were considered clinically unnecessary and 739 out of 784 medically unnecessary RTEDs (94.3%) were attributed to a mismatch between parental expectations and natural progression of disease that did not require Emergency Department (ED) reassessment or interventions. Eighty per cent of reviewed written discharge instructions lacked any anticipatory guidance around symptom range and duration and 21.2% contained instructions to return to the ED for signs and symptoms which do not require ED care. An administrative or system challenge was noted as the reason for the unnecessary and unscheduled RTED in 17.5%. In 3.4% of cases, nonemergency consultants were responsible for the disposition decision and discharge process. CONCLUSIONS: Unscheduled unnecessary return visits to our ED contribute to a significant proportion of our annual volume. Providing discharge instructions that help families distinguish expected range and duration of symptoms from signs requiring ED care was identified as a potential strategy to impact the frequency of unscheduled RTED.

System outcomes associated with a pediatric emergency department clinical decision unit.

OBJECTIVES: Our objectives were to describe disposition decisions and emergency department return (EDR) rates following a clinical decision unit (CDU) stay; and to determine changes to short stay (<48 hour) hospitalization rates after CDU implementation. METHODS: We conducted a retrospective cohort study of pediatric emergency department (PED) visits with a CDU stay from January 1 to December 31, 2015. Health records data were extracted onto standardized online forms, then used to determine disposition and 7-day EDR rates. Two trained investigators blindly reviewed EDR visits to determine if they were related to the index CDU stay. We compared short stay inpatient admission rates (i.e., hospital length of stay <48 hours) in 2013 and 2015, before and after CDU implementation. RESULTS: Of 1696 index CDU stays, 1503 (89%) were discharged, and 139 discharged patients (9.2%) had ≥1 clinically-related EDR. Median (IQR) CDU length of stay (LOS) was 4.4 hours (2.7-7.8) and total PED LOS (including CDU) was 7.8 hours (5.4-12.0). Asthma represented 31% of cases. Short stay hospitalization rate decreased from 3.62% in 2013 to 3.23% in 2015 (difference=0.39%; 95% CI=0.15-0.63; p=0.001). CONCLUSIONS: Most CDU patients were discharged, but 9% had a clinically-related ED revisit. CDU implementation was associated with a small but significant reduction in short stay hospitalization.

Opioid Prescribing Practices for Pediatric Headache.

OBJECTIVES: To characterize the frequency of opioid prescribing for pediatric headache in both ambulatory and emergency department (ED) settings, including prescribing rates by provider type. STUDY DESIGN: A retrospective cohort study of Washington State Medicaid beneficiaries, aged 7-17 years, with an ambulatory care or ED visit for headache between January 1, 2012, and September 30, 2015. The primary outcome was any opioid prescribed within 1 day of the visit. RESULTS: A total of 51 720 visits were included, 83% outpatient and 17% ED. There was a predominance of female (63.2%) and adolescent (59.4%) patients, and 30.5% of encounters involved a pediatrician. An opioid was prescribed in 3.9% of ED and 1.0% of ambulatory care visits (P < .001). Pediatricians were less likely to prescribe opioids in both ED (-2.70 percentage point; 95% CI, -3.53 to -1.88) and ambulatory settings (-0.31 percentage point; 95% CI, -0.54 to -0.08; P < .001). CONCLUSIONS: Opioid prescribing rates for pediatric headache were low, but significant variation was observed by setting and provider specialty. We identified opioid prescribing by nonpediatricians as a potential target for quality improvement efforts.

Low-Dose Propofol for Pediatric Migraine: A Prospective, Randomized Controlled Trial.

BACKGROUND: Migraine headaches are a common reason for pediatric emergency department (ED) visits. Small studies suggest the potential efficacy of sub-anesthetic doses of propofol for migraine with a favorable side effect profile and potentially decreased length of stay (LOS). OBJECTIVE: The objective of this study was to compare the efficacy of low-dose propofol (LDP) to standard therapy (ST) in pediatric migraine treatment. METHODS: We conducted a prospective, pragmatic randomized controlled trial from April 2014 through June 2016 in the ED at two pediatric hospitals. Patients aged 7-19 years were eligible if they were diagnosed with migraine by the emergency physician and had a presenting visual analog pain score (VAS) of 6-10. Primary outcome was the percent of pain reduction. Secondary outcomes were ED LOS, 24-h rebound headache, return visits to the ED, and adverse reactions. RESULTS: Seventy-four patients were enrolled, but 8 were excluded, leaving 66 patients in the final analysis (36 ST, 30 LDP). Pain reduction was 59% for ST and 51% for LDP (p = 0.34) with 72.2% vs. 73.3% achieving a VAS ≤ 4 with initial therapy (p = 0.92). There was a nonsignificant trend toward shorter median LOS from drug administration to final disposition favoring propofol (79 min vs. 111 min; p = 0.09). Rebound headache was significantly more common in the ST vs. LDP group (66.7% vs. 25.0%; p = 0.01). CONCLUSIONS: LDP did not achieve better pain reduction than ST, however, LDP was associated with significantly fewer rebound headaches and a nonsignificant trend toward shorter median LOS from drug administration to disposition.

Relative Effectiveness of Dopamine Antagonists for Pediatric Migraine in the Emergency Department.

OBJECTIVE: Migraine headaches are common in the pediatric emergency department. The mainstay of abortive treatment consists of nonsteroidal anti-inflammatories and dopamine antagonists. The objective of this study was to compare the effectiveness of 3 commonly used dopamine antagonists to abort pediatric migraine. METHODS: This was a retrospective cohort study of all patients who presented to the pediatric emergency department at a tertiary care pediatric hospital between January 2010 and December 2013. Patients were treated for a migraine headache with a combination of ketorolac and one of the following dopamine antagonists: prochlorperazine, metoclopramide, or promethazine. The primary outcome was treatment failure and receiving non-evidence-based treatment defined by the need for opioids. Secondary outcomes included pain score reduction and return visit within 48 hours. RESULTS: There were 57 patients during this period with 67 visits that met inclusion criteria: 27 (40.3%) visits in which patients were treated with prochlorperazine, 23 (34.3%) visits in which patients were treated with metoclopramide, and 17 (25.4%) visits in which patients were treated with promethazine. Across visits, the mean age was 14.5 years, and 63% were women. Opioids were given for treatment failure in 8.7% of visits in which patients received prochlorperazine, 25% in which patients received metoclopramide, and 42.8% in which patients received promethazine. Patients treated with promethazine had significantly higher odds of needing opioids and experiencing less than 50% reduction in pain score compared with prochlorperazine after adjusting for patient characteristics. CONCLUSIONS: This study suggests variable efficacy among 3 commonly used dopamine antagonists for pediatric migraine headache. Promethazine seems least effective and results in higher use of opioids compared with other available dopamine antagonists.

Return visits to the pediatric emergency department: A multicentre retrospective cohort study.

OBJECTIVE: Return visits to the emergency department (RTED) for the same clinical complaint occur in 2.7% to 8.1% of children presenting to pediatric emergency departments (PEDs). Most studies examining RTEDs have focused solely on PEDs and do not capture children returning to other local emergency departments (EDs). Our objective was to measure the frequency and characterize the directional pattern of RTED to any of 18 EDs serving a large geographic area for children initially evaluated at a PED. METHODS: We conducted a retrospective cohort study of all visits to a referral centre PED between August 2012 and August 2013. We compared demographic variables between children with and without an RTED, measures of flow and disposition outcomes between the initial (index) visit and RTED, and between RTED to the original PED versus to other EDs in the community. RESULTS: Among all PED visits, 7.6% had an RTED within 7 days, of which 13% were to a facility other than the original PED. Children with an RTED had higher acuity and longer length of stay on their index visit. They were also more likely to be admitted on a subsequent visit than the overall PED population. RTED to the original PED had a longer waiting time (WT), length of stay, and more frequently resulted in hospitalization than RTED to a general ED. CONCLUSIONS: A significant proportion of RTED occur at a site other than where the original ED visit occurred. Examining RTED to and from only PEDs underestimates its burden on emergency health services.

Topiramate for pediatric migraine prevention.

Question I have several teenagers in my clinic with migraine headache and some of them have frequent episodes that cause considerable interference with daily activity. I would like to offer them prophylactic therapy to reduce the frequency of their migraine episodes. Is topiramate an effective and safe option for adolescents? Answer Both Health Canada and the US Food and Drug Administration have approved the use of topiramate for migraine prevention in adults; however, only the US Food and Drug Administration has approved topiramate for migraine prophylaxis in adolescents 12 to 17 years of age. Although several studies support its effectiveness in preventing migraine, most of these studies are small; and a recent large multicentre, randomized placebo-controlled trial was stopped early when no benefit was shown over placebo. Adverse effects of topiramate are mild and typically resolve over time. The recommended dosage is 2 mg/kg per day, up to an adult dose of 100 mg/d.

Pediatric Disaster Triage: Multiple Simulation Curriculum Improves Prehospital Care Providers' Assessment Skills.

OBJECTIVE: Paramedics and emergency medical technicians (EMTs) triage pediatric disaster victims infrequently. The objective of this study was to measure the effect of a multiple-patient, multiple-simulation curriculum on accuracy of pediatric disaster triage (PDT). METHODS: Paramedics, paramedic students, and EMTs from three sites were enrolled. Triage accuracy was measured three times (Time 0, Time 1 [two weeks later], and Time 2 [6 months later]) during a disaster simulation, in which high and low fidelity manikins and actors portrayed 10 victims. Accuracy was determined by participant triage decision concordance with predetermined expected triage level (RED [Immediate], YELLOW [Delayed], GREEN [Ambulatory], BLACK [Deceased]) for each victim. Between Time 0 and Time 1, participants completed an interactive online module, and after each simulation there was an individual debriefing. Associations between participant level of training, years of experience, and enrollment site were determined, as were instances of the most dangerous mistriage, when RED and YELLOW victims were triaged BLACK. RESULTS: The study enrolled 331 participants, and the analysis included 261 (78.9%) participants who completed the study, 123 from the Connecticut site, 83 from Rhode Island, and 55 from Massachusetts. Triage accuracy improved significantly from Time 0 to Time 1, after the educational interventions (first simulation with debriefing, and an interactive online module), with a median 10% overall improvement (p < 0.001). Subgroup analyses showed between Time 0 and Time 1, paramedics and paramedic students improved more than EMTs (p = 0.002). Analysis of triage accuracy showed greatest improvement in overall accuracy for YELLOW triage patients (Time 0 50% accurate, Time1 100%), followed by RED patients (Time 0 80%, Time 1 100%). There was no significant difference in accuracy between Time 1 and Time 2 (p = 0.073). CONCLUSION: This study shows that the multiple-victim, multiple-simulation curriculum yields a durable 10% improvement in simulated triage accuracy. Future iterations of the curriculum can target greater improvements in EMT triage accuracy.

Inpatient Pediatric Migraine Treatment: Does Choice of Abortive Therapy Affect Length of Stay?

OBJECTIVE: To describe the inpatient management of pediatric migraine and the association between specific medications and hospital length of stay (LOS). STUDY DESIGN: Historical cohort study review of patients age <19 years of age admitted to a single tertiary care children's hospital between 2010 and 2015 for treatment of migraine headache. RESULTS: The cohort consisted of 58 encounters with an average patient age of 14.3 years (SD 3.2 years) with a female predominance (62%). The mean number of inpatient medications received by patients was 3 (range 1-7), with dopamine antagonists and dihydroergotamine used most commonly (67% and 59% of encounters, respectively). The average LOS was 56 hours (95% CI 48.2-63.2) and did not vary by medication received, although patients who received an opioid had a significantly longer LOS (79.2 vs 47.9 hours respectively; P < .001). CONCLUSIONS: Children admitted to the hospital for treatment of migraine headache frequently require a large number of medications over an average hospital LOS of more than 2 days without apparent differences based on medication received other than prolonged stays for subjects who received opioids.

Time on the scene and interventions are associated with improved survival in pediatric out-of-hospital cardiac arrest.

BACKGROUND: Survival is less than 10% for pediatric patients following out-of-hospital cardiac arrest. It is not known if more time on the scene of the cardiac arrest and advanced life support interventions by emergency services personnel are associated with improved survival. AIM: This study was performed to determine which times on the scene and which prehospital interventions were associated with improved survival. METHODS: We studied patients aged 3 days to 19 years old with out-of-hospital cardiac arrest, using the Resuscitation Outcomes Consortium cardiac arrest database from 11 North American regions, from 2005 to 2012. We evaluated survival to hospital discharge according to on-scene times (<10, 10 to 35 and >35 min). RESULTS: Data were available for 2244 patients (1017 infants, 594 children and 633 adolescents). Infants had the lowest rate of survival (3.7%) compared to children (9.8%) and adolescents (16.3%). Survival improved over the 7 year study period especially among adolescents. Survival was highest in the 10 to 35 min on-scene time group (10.2%) compared to the >35 min. group (6.9%) and the <10 min. group (5.3%, p=0.01). Intravenous or intra-osseous access attempts and fluid administration were associated with improved survival, whereas advanced airway attempts were not associated with survival and resuscitation drugs were associated with worse survival. CONCLUSIONS: In this observational study, a scene time of 10 to 35 min was associated with the highest survival, especially among adolescents. Access for fluid resuscitation was associated with increased survival but advanced airway and resuscitation drugs were not.
