ABSTRACT

BACKGROUND: Medication dosing errors are common in prehospital pediatric patients. Prior work has shown the overall medication error rate by emergency medical services (EMS) in Michigan was 34.7%. To reduce these errors, the state of Michigan implemented a pediatric dosing reference in 2014 listing medication doses and volume to be administered. OBJECTIVE: To examine changes in pediatric dosing errors by EMS in Michigan after implementation of the pediatric dosing reference. METHODS: We conducted a retrospective review of the Michigan Emergency Medical Services Information System of children ≤ 12 years of age from June 2016-May 2017 treated by 16 EMS agencies. Agencies were a mix of public, private, third-service, and fire-based. A dosing error was defined as >20% deviation from the weight-appropriate dose listed on the pediatric dosing reference. Descriptive statistics with confidence intervals and standard deviations are reported. RESULTS: During the study period, there were 9,247 pediatric encounters, of whom 727 (7.9%) received medications and are included in the study. There were 1078 medication administrations, with 380 dosing errors (35.2% [95% CI 25.3-48.4]). The highest error rates were for dextrose 50% (3/4 or 75% [95% CI 32.57-100.0]) and glucagon (3/4 or 75% [95% CI 32.57-100.0]). The next highest proportions of incorrect doses were opioids: intranasal fentanyl (11/16 or 68.8% [95% CI 46.04-91.46]) and intravenous fentanyl (89/130 or 68.5% [95% CI 60.47-76.45]). Morphine had a much lower error rate (24/51 or 47.1% [95% CI 33.36-60.76]). Midazolam had the third highest error rate, for intravenous (27/50 or 54.0% [95% CI (40.19-67.81]) and intramuscular (25/68 or 36.8% [95% CI 40.19-67.81]) routes. Epinephrine 1 mg/10 ml had an incorrect dosage rate of 35/119 (29.4% [95% CI 20.64-36.99]). Asthma medications had the lowest rate of incorrect dosing (albuterol sulfate 9/247 or 3.6% [95% CI 1.31-5.98]). CONCLUSIONS: Medications administered to prehospital pediatric patients continue to demonstrate dosing errors despite pediatric dosing reference implementation. Although there have been improvements in error rates in asthma medications, the overall error rate has increased. Continued work to build patient safety strategies to reduce pediatric medication dosing errors by EMS is needed.

ABSTRACT

It is unknown whether febrile infants 29 to 60 days old with positive urinalysis results require routine lumbar punctures for evaluation of bacterial meningitis. OBJECTIVE: To determine the prevalence of bacteremia and/or bacterial meningitis in febrile infants ≤60 days of age with positive urinalysis (UA) results. METHODS: Secondary analysis of a prospective observational study of noncritical febrile infants ≤60 days between 2011 and 2019 conducted in the Pediatric Emergency Care Applied Research Network emergency departments. Participants had temperatures ≥38°C and were evaluated with blood cultures and had UAs available for analysis. We report the prevalence of bacteremia and bacterial meningitis in those with and without positive UA results. RESULTS: Among 7180 infants, 1090 (15.2%) had positive UA results. The risk of bacteremia was higher in those with positive versus negative UA results (63/1090 [5.8%] vs 69/6090 [1.1%], difference 4.7% [3.3% to 6.1%]). There was no difference in the prevalence of bacterial meningitis in infants ≤28 days of age with positive versus negative UA results (∼1% in both groups). However, among 697 infants aged 29 to 60 days with positive UA results, there were no cases of bacterial meningitis in comparison to 9 of 4153 with negative UA results (0.2%, difference -0.2% [-0.4% to -0.1%]). In addition, there were no cases of bacteremia and/or bacterial meningitis in the 148 infants ≤60 days of age with positive UA results who had the Pediatric Emergency Care Applied Research Network low-risk blood thresholds of absolute neutrophil count <4 × 103 cells/mm3 and procalcitonin <0.5 ng/mL. CONCLUSIONS: Among noncritical febrile infants ≤60 days of age with positive UA results, there were no cases of bacterial meningitis in those aged 29 to 60 days and no cases of bacteremia and/or bacterial meningitis in any low-risk infants based on low-risk blood thresholds in both months of life. These findings can guide lumbar puncture use and other clinical decision making.

ABSTRACT

Background: Prehospital pediatric drug dosing errors occur at a high rate. Multiple factors contribute to these errors. The contribution of weight estimation errors to drug dosing errors is unknown. We describe methods used to obtain weights and resulting drug dosing errors. Methods: As part of a quality improvement study in 16 EMS agencies, we conducted four simulated pediatric scenarios: seizing, hypoglycemic infant, infant cardiac arrest, 18-month old burn and a 5-year old with anaphylactic shock. Crews used their regular drug bags and equipment. Simulations were observed by study team members with video review and scored on a standardized scoring sheet. Results: 142 scenarios were completed. Methods to obtain patient weights were: asking parent 17/142 (12.0%), patient age 35/142 (24.8%) and Broselow-Luten Tape (BLT) 89/142 (63.1%). There were 19 (13.4% 95% CI 8.5, 20.0) incorrect weight estimations resulting in 18 (12.7% 95% CI 8.2, 19.2) dosing errors (1 asking parent, 9 patient age and 8 BLT). Ten dosing errors were directly caused by weight estimation errors. In 41/89 (46.1% 95%CI 36.1, 56.4) BLT uses there was a near-miss error that did not result in a dosing error. One pound to kilogram conversion error occurred. Conclusions: BLT is the most frequently used method to obtain a patient weight. Drug dosing errors were most frequent with patient age, followed by BLT and asking the parent. System-based solutions-weight determination hierarchy, not using the BLT on seated patients, and more frequent training and practice with the BLT-are needed to improve drug-dosing accuracy.

ABSTRACT

INTRO: Transposition of the great arteries (TGA) is a rare cyanotic congenital heart defect (CHD) typically presenting the first month of life. Late presentations may occur in patients with associated cardiac anomalies allowing for mixing of oxygenated and deoxygenated blood, such as ventral septal defects or large atrial septal defects (ASD). We present a case of a late-presenting TGA with no ventral septal defect, and only small ASD and patent ductus arteriosus (PDA). CASE: A 2-month-old female infant presented to a rural emergency department with respiratory distress for 1 day. On arrival, she was cyanotic with only mild improvement in oxygen saturations on 15-L non-rebreather. Grade IV/VI murmur was noted, and prostaglandin E was started. She required intubation after becoming apneic and was transported to the local pediatric referral hospital. There, echocardiography showed dextro-type TGA, with 8-mm ASD with minimal gradient, small PDA with left to right flow, and ventral septal bowing. She underwent balloon septostomy and then atrial switch, which was well tolerated. DISCUSSION: Our case is unique because of the patient's late presentation and prior lack of symptoms, given minimal levels of blood mixing though small ASD and PDA. Most TGA cases are now identified during prenatal ultrasound or with CHD screening pulse oximetry before discharge from the newborn nursery; however rare cases of late-presenting TGA may exist. CONCLUSION: Practitioners must maintain consideration of TGA, even after the newborn period, despite advances in newborn CHD screening in infants who present with new-onset respiratory distress without infection.

ABSTRACT

BACKGROUND: Millions of patients receive medications in the Emergency Medical Services (EMS) setting annually, and dosing safety is critically important. The need for weight-based dosing in pediatric patients and variability in medication concentrations available in the EMS setting may require EMS providers to perform complex calculations to derive the appropriate dose to deliver. These factors can significantly increase the risk for harm when dose calculations are inaccurate or incorrect. METHODS: We conducted a scoping review of the EMS, interfacility transport and emergency medicine literature regarding pediatric medication dosing safety. A priori, the authors identified four research topics: (1) what are the greatest safety threats that result in significant dosing errors that potentially result in harm to patients, (2) what practices or technologies are known to enhance dosing safety, (3) can data from other settings be extrapolated to the EMS environment to inform dosing safety, and (4) what impact could standardization of medication formularies have on enhancing dosing safety. To address these topics, 17 PICO (Patient, Intervention, Comparison, Outcome) questions were developed and a literature search was performed. RESULTS: After applying exclusion criteria, 70 articles were reviewed. The methods for the investigation, findings from these articles and how they inform EMS medication dosing safety are summarized here. This review yielded 11 recommendations to improve safety of medication delivery in the EMS setting. CONCLUSION: These recommendations are summarized in the National Association of EMS Physicians® position statement: Medication Dosing Safety for Pediatric Patients in Emergency Medical Services.

ABSTRACT

OBJECTIVE: Few prospective studies have assessed the occurrence of radiographic pneumonia in young febrile infants. We analyzed factors associated with radiographic pneumonias in febrile infants 60 days or younger evaluated in pediatric emergency departments. STUDY DESIGN: We conducted a planned secondary analysis of a prospective cohort study within 26 emergency departments in a pediatric research network from 2008 to 2013. Febrile (≥38°C) infants 60 days or younger who received chest radiographs were included. Chest radiograph reports were categorized as "no," "possible," or "definite" pneumonia. We compared demographics, Yale Observation Scale scores (>10 implying ill appearance), laboratory markers, blood cultures, and viral testing among groups. RESULTS: Of 4778 infants, 1724 (36.1%) had chest radiographs performed; 2.7% (n = 46) had definite pneumonias, and 3.9% (n = 67) had possible pneumonias. Patients with definite (13/46 [28.3%]) or possible (15/67 [22.7%]) pneumonias more frequently had Yale Observation Scale score >10 compared with those without pneumonias (210/1611 [13.2%], P = 0.002) in univariable and multivariable analyses. Median white blood cell count (WBC), absolute neutrophil count (ANC), and procalcitonin (PCT) were higher in the definite (WBC, 11.5 [interquartile range, 9.8-15.5]; ANC, 5.0 [3.2-7.6]; PCT, 0.4 [0.2-2.1]) versus no pneumonia (WBC, 10.0 [7.6-13.3]; ANC, 3.4 [2.1-5.4]; PCT, 0.2 [0.2-0.3]; WBC, P = 0.006; ANC, P = 0.002; PCT, P = 0.046) groups, but of unclear clinical significance. There were no cases of bacteremia in the definite pneumonia group. Viral infections were more frequent in groups with definite (25/38 [65.8%]) and possible (28/55 [50.9%]) pneumonias than no pneumonias (534/1185 [45.1%], P = 0.02). CONCLUSIONS: Radiographic pneumonias were uncommon, often had viruses detected, and were associated with ill appearance, but few other predictors, in febrile infants 60 days or younger.

ABSTRACT

Background: Drug dosing errors occur at a high rate for prehospital pediatric patients. To reduce errors, Michigan implemented a state-wide pediatric dosing reference (PDR), with doses listed in milliliters, the requirement that doses be drawn into a smaller syringe from a pre-loaded syringe using a stopcock, and dilution of certain drugs to different concentrations.Purpose: To evaluate the rate of medication errors, including errors of omission and commission, after implementation of a state-wide PDR.Methods: EMS crews from 15 agencies completed 4 validated, simulation scenarios: an infant seizing, an infant cardiac arrest, an 18-month-old with a burn, and 5-year-old with anaphylactic shock. Agencies were private, public, not-for-profit, for-profit, urban, rural, fire-based, and third service. EMS crews used their regular equipment and were required to carry out all the steps to administer a drug dose. Two evaluators scored crew performance via direct observation and video review. An error was defined as [Formula: see text]20% difference compared to the weight-appropriate dose. Descriptive statistics were utilized.Results: A total of 142 simulations were completed. The majority of crews were (58.3%) Emergency Medical Technician-Paramedic (EMTP)/EMTP. For the cardiac arrest scenario, 51/70 (72.9%; 95% CI: 60.9%, 82.8%) epinephrine doses were correct. There were 6 (8.6%, 95% CI: 2.0%, 15.1%) 10-fold overdoses and one (1.4%; 95% CI: -1.4%, 4.2%), 10-fold under dose. In the seizure scenario, 28/50 (56.0%; 95% CI: 42.2%, 69.8%) benzodiazepine doses were correct; 6/18 (33.3%; 95% CI: 11.5%, 55.1%) drug dilutions were incorrect resulting in dosing errors. Unrecognized air was frequently entrained into the administration syringe resulting in under doses. Overall, 31.2% (95% CI: 25.5%, 36.6%) of drug doses were incorrect. Obtaining an incorrect weight led to a drug dosing error in 18/142 (12.7%, 95% CI: 7.2%, 18.2%) cases. Errors of omission included failure to check blood sugar in the seizure scenario and failure to administer epinephrine and a fluid bolus in anaphylactic shock.Conclusion: Despite implementation of a PDR, dosing errors, including 10-fold errors, still occur at a high rate. Errors occur with dilution and length-based tape use. Further error reduction strategies, beyond a PDR and that target errors of omission, are needed for pediatric prehospital drug administration.

ABSTRACT

BACKGROUND: Febrile infants commonly present to emergency departments for evaluation. OBJECTIVE: We describe the variation in diagnostic testing and hospitalization of febrile infants ≤60 days of age presenting to the emergency departments in the Pediatric Emergency Care Applied Research Network. METHODS: We enrolled a convenience sample of non-critically ill-appearing febrile infants (temperatures ≥38.0°C/100.4°F) ≤60 days of age who were being evaluated with blood cultures in 26 Pediatric Emergency Care Applied Research Network emergency departments between 2008 and 2013. Patients were divided into younger (0-28 days of age) and older (29-60 days of age) cohorts for analysis. We evaluated diagnostic testing and hospitalization rates by infant age group using chi-square tests and by site using analysis of variance. RESULTS: Four thousand seven hundred seventy-eight patients were eligible for analysis, of whom 1517 (32%) were 0-28 days of age. Rates of lumbar puncture and hospitalization were high (>90%) among infants ≤28 days of age, with chest radiography (35.5%) and viral testing (66.2%) less commonly obtained. Among infants 29-60 days of age, lumbar puncture (69.5%) and hospitalization (64.4%) rates were lower and declined with increasing age, with chest radiography (36.5%) use unchanged and viral testing (52.7%) slightly decreased. There was substantial variation between sites in the older cohort of infants, with lumbar puncture and hospitalization rates ranging from 40% to 90%. CONCLUSIONS: The evaluation and disposition of febrile infants ≤60 days of age is highly variable, particularly among infants who are 29-60 days of age. This variation demonstrates an opportunity to modify diagnostic and management strategies based on current epidemiology to safely decrease invasive testing and hospitalization.

ABSTRACT

Importance: In young febrile infants, serious bacterial infections (SBIs), including urinary tract infections, bacteremia, and meningitis, may lead to dangerous complications. However, lumbar punctures and hospitalizations involve risks and costs. Clinical prediction rules using biomarkers beyond the white blood cell count (WBC) may accurately identify febrile infants at low risk for SBIs. Objective: To derive and validate a prediction rule to identify febrile infants 60 days and younger at low risk for SBIs. Design, Setting, and Participants: Prospective, observational study between March 2011 and May 2013 at 26 emergency departments. Convenience sample of previously healthy febrile infants 60 days and younger who were evaluated for SBIs. Data were analyzed between April 2014 and April 2018. Exposures: Clinical and laboratory data (blood and urine) including patient demographics, fever height and duration, clinical appearance, WBC, absolute neutrophil count (ANC), serum procalcitonin, and urinalysis. We derived and validated a prediction rule based on these variables using binary recursive partitioning analysis. Main Outcomes and Measures: Serious bacterial infection, defined as urinary tract infection, bacteremia, or bacterial meningitis. Results: We derived the prediction rule on a random sample of 908 infants and validated it on 913 infants (mean age was 36 days, 765 were girls [42%], 781 were white and non-Hispanic [43%], 366 were black [20%], and 535 were Hispanic [29%]). Serious bacterial infections were present in 170 of 1821 infants (9.3%), including 26 (1.4%) with bacteremia, 151 (8.3%) with urinary tract infections, and 10 (0.5%) with bacterial meningitis; 16 (0.9%) had concurrent SBIs. The prediction rule identified infants at low risk of SBI using a negative urinalysis result, an ANC of 4090/µL or less (to convert to ×109 per liter, multiply by 0.001), and serum procalcitonin of 1.71 ng/mL or less. In the validation cohort, the rule sensitivity was 97.7% (95% CI, 91.3-99.6), specificity was 60.0% (95% CI, 56.6-63.3), negative predictive value was 99.6% (95% CI, 98.4-99.9), and negative likelihood ratio was 0.04 (95% CI, 0.01-0.15). One infant with bacteremia and 2 infants with urinary tract infections were misclassified. No patients with bacterial meningitis were missed by the rule. The rule performance was nearly identical when the outcome was restricted to bacteremia and/or bacterial meningitis, missing the same infant with bacteremia. Conclusions and Relevance: We derived and validated an accurate prediction rule to identify febrile infants 60 days and younger at low risk for SBIs using the urinalysis, ANC, and procalcitonin levels. Once further validated on an independent cohort, clinical application of the rule has the potential to decrease unnecessary lumbar punctures, antibiotic administration, and hospitalizations.

ABSTRACT

STUDY OBJECTIVE: To describe the current epidemiology of bacteremia in febrile infants 60 days of age and younger in the Pediatric Emergency Care Applied Research Network (PECARN). METHODS: We conducted a planned secondary analysis of a prospective observational study of febrile infants 60 days of age and younger presenting to any of 26 PECARN emergency departments (2008 to 2013) who had blood cultures obtained. We excluded infants with significant comorbidities or critically ill appearance. The primary outcome was prevalence of bacteremia. RESULTS: Of 7,335 screened infants, 4,778 (65.1%) had blood cultures and were enrolled. Of these patients, 84 had bacteremia (1.8%; 95% confidence interval [CI] 1.4% to 2.2%). The prevalence of bacteremia in infants aged 28 days or younger (47/1,515) was 3.1% (95% CI 2.3% to 4.1%); in infants aged 29 to 60 days (37/3,246), 1.1% (95% CI 0.8% to 1.6%). Prevalence differed by week of age for infants 28 days of age and younger (0 to 7 days: 4/156, 2.6%; 8 to 14 days: 19/356, 5.3%; 15 to 21 days: 15/449, 3.3%; and 22 to 28 days: 9/554, 1.6%). The most common pathogens were Escherichia coli (39.3%; 95% CI 29.5% to 50.0%) and group B streptococcus (23.8%; 95% CI 16.0% to 33.9%). Bacterial meningitis occurred in 19 of 1,515 infants 28 days of age and younger (1.3%; 95% CI 0.8% to 2.0%) and 5 of 3,246 infants aged 29 to 60 days (0.2%; 95% CI 0.1% to 0.4%). Of 84 infants with bacteremia, 36 (42.9%; 95% CI 32.8% to 53.5%) had urinary tract infections (E coli 83%); 11 (13.1%; 95% CI 7.5% to 21.9%) had bacterial meningitis. CONCLUSION: The prevalence of bacteremia and meningitis among febrile infants 28 days of age and younger is high and exceeds that observed in infants aged 29 to 60 days. E coli and group B streptococcus are the most common bacterial pathogens.

ABSTRACT

BACKGROUND: Pediatric drug dosing errors occur at a high rate in the prehospital environment. OBJECTIVE: To describe paramedic training and practice regarding pediatric drug administration, exposure to pediatric drug dose errors and safety culture among paramedics and EMS agencies in a national sample. METHODS: An electronic questionnaire was sent to a random sample of 10,530 nationally certified paramedics. Descriptive statistics were calculated. RESULTS: There were 1,043 (9.9%) responses and 1,014 paramedics met inclusion criteria. Nearly half (43.0%) were familiar with a case where EMS personnel delivered an incorrect pediatric drug dose. Over half (58.5%) believed their initial paramedic program did not include enough pediatric training. Two-thirds (66.0%) administered a pediatric drug dose within the past year. When estimating the weight of a pediatric patient, 54.2% used a length-based tape, while 35.8% asked the parent or guardian, and 2.5% relied on a smart phone application. Only 19.8% said their agency had an anonymous error-reporting system and 50.7% believed they could report an error without fear of disciplinary action. For solutions, 89.0% believed an EMS-specific Broselow-Luten Tape would be helpful, followed by drug dosing cards in milliliters (83.0%) and changing content of standardized pediatric courses to be more relevant (77.7%). CONCLUSION: This national survey demonstrated a significant number of paramedics are aware of a pediatric dosing error, safety systems specific to pediatric patients are lacking, and that paramedics view pediatric drug cards and eliminating drug calculations as helpful. Pediatric drug-dosing safety in the prehospital environment can be improved.

ABSTRACT

OBJECTIVES: Computed tomography (CT) is often used in the emergency department (ED) evaluation of children with posttraumatic seizures (PTS); however, the frequency of traumatic brain injuries (TBIs) and short-term seizure recurrence is lacking. Our main objective was to evaluate the frequency of TBIs on CT and short-term seizure recurrence in children with PTS. We also aimed to determine the associations between the likelihood of TBI on CT with the timing of onset of PTS after the traumatic event and duration of PTS. Finally, we aimed to determine whether patients with normal CT scans and normal neurological examinations are safe for discharge from the ED. METHODS: This was a planned secondary analysis from a prospective observational cohort study to derive and validate a neuroimaging decision rule for children after blunt head trauma at 25 EDs in the Pediatric Emergency Care Applied Research Network. We evaluated children < 18 years with head trauma and PTS between June 2004 and September 2006. We assessed TBI on CT, neurosurgical interventions, and recurrent seizures within 1 week. Patients discharged from the ED were contacted by telephone 1 week to 3 months later. RESULTS: Of 42,424 children enrolled, 536 (1.3%, 95% confidence interval [CI] = 1.2%-1.4%) had PTS. A total of 466 of 536 (86.9%, 95% CI = 83.8%-89.7%) underwent CT in the ED. TBIs on CT were identified in 72 (15.5%, 95% CI = 12.3%-19.1%), of whom 20 (27.8%, 95% CI = 17.9%-39.6%) underwent neurosurgical intervention and 15 (20.8%, 95% CI = 12.2%-32.0%) had recurrent seizures. Of the 464 without TBIs on CT (or no CTs performed), 457 had recurrent seizure status known, and five (1.1%, 95 CI = 0.4%-2.5%) had recurrent seizures; four of five presented with Glasgow Coma Scale scores < 15. None of the 464 underwent neurosurgical intervention. We found significant associations between likelihood of TBI on CT with longer time until the PTS after the traumatic event (p = 0.006) and longer duration of PTS (p < 0.001). CONCLUSIONS: Children with PTS have a high likelihood of TBI on CT, and those with TBI on CT frequently require neurosurgical interventions and frequently have recurrent seizures. Those without TBIs on CT, however, are at low risk of short-term recurrent seizures, and none required neurosurgical interventions. Therefore, if CT-negative and neurologically normal, patients with PTS may be safely considered for discharge from the ED.

ABSTRACT

OBJECTIVES: Emergency medicine (EM) trainees are expected to learn to provide acute care for patients of all ages. The American Council for Graduate Medical Education provides some guidance on topics related to caring for pediatric patients; however, education about pediatric topics varies across residency programs. The goal of this project was to develop a consensus curriculum for teaching pediatric emergency care. METHODS: We recruited 13 physicians from six academic health centers to participate in a three-round electronic modified Delphi project. Participants were selected on the basis of expertise with both EM resident education and pediatric emergency care. The first modified Delphi survey asked participants to generate the core knowledge, skills, and experiences needed to prepare EM residents to effectively treat children in an acute care setting. The qualitative data from the first round was reformulated into a second-round questionnaire. During the second round, participants used rating scales to prioritize the curriculum content proposed during the first round. In round 3, participants were asked to make a determination about each curriculum topic using a three-point scale labeled required, optional, or not needed. RESULTS: The first modified Delphi round yielded 400 knowledge topics, 206 clinical skills, and 44 specific types of experience residents need to prepare for acute pediatric patient care. These were narrowed to 153 topics, 84 skills, and 28 experiences through elimination of redundancy and two rounds of prioritization. The final lists contain topics classified by highly recommended, partially recommended, and not recommended. The partially recommended category is intended to help programs tailor their curriculum to the unique needs of their learners as well as account for variability between 3- and 4-year programs and the amount of time programs allocate to pediatric education. CONCLUSION: The modified Delphi process yielded the broad outline of a consensus core pediatric emergency care curriculum.

ABSTRACT

BACKGROUND: Prehospital pediatric drug dosing errors affect 56,000 U.S. children annually. An accurate weight is the first step in accurate dosing. To date, the accuracy of Emergency Medical Dispatcher (EMD) obtained weights has not been evaluated. We hypothesized that EMD could obtain accurate pediatric weights. METHODS: We used a convenience sample of patients 12 years and younger that were transported by EMS to one children's hospital. EMD obtained patient weight (DW) from the 9-1-1 caller. Paramedics reported their estimate of the patient's weight on arrival to the hospital (PW). The DW and PW were compared to the hospital scale weight (HW) for accuracy. RESULTS: A total of 197 patients were included. Parent/guardians were the most frequent 9-1-1 callers (74%). The most frequent method utilized by paramedics to obtain patient weight was to ask a family member. For 0-2 year olds, the mean differences between HW and DW/PW were 0.239kg (SD 3.117)/ -0.374 (SD 2.528). For 3-7 year olds, the mean differences between HW and DW/PW were 0.041kg (SD 4.684)/1.007 (SD 2.466). For 8-11 year olds the mean difference between HW and DW/PW was 2.768 kg (SD 10.926)/ 1.919 (SD 6.909). CONCLUSION: EMD were able to obtain pediatric patient weights with relative accuracy for patients 0-7 year old. Using this EMD-obtained weight to carry out a drug dose calculation would be unlikely to result in a clinically significant dose error in the vast majority of cases. Communicating an EMD-obtained weight to EMS crews en route to a pediatric patient offers additional preparation time for drug calculations, which could improve accuracy.

ABSTRACT

IMPORTANCE: Young febrile infants are at substantial risk of serious bacterial infections; however, the current culture-based diagnosis has limitations. Analysis of host expression patterns ("RNA biosignatures") in response to infections may provide an alternative diagnostic approach. OBJECTIVE: To assess whether RNA biosignatures can distinguish febrile infants aged 60 days or younger with and without serious bacterial infections. DESIGN, SETTING, AND PARTICIPANTS: Prospective observational study involving a convenience sample of febrile infants 60 days or younger evaluated for fever (temperature >38° C) in 22 emergency departments from December 2008 to December 2010 who underwent laboratory evaluations including blood cultures. A random sample of infants with and without bacterial infections was selected for RNA biosignature analysis. Afebrile healthy infants served as controls. Blood samples were collected for cultures and RNA biosignatures. Bioinformatics tools were applied to define RNA biosignatures to classify febrile infants by infection type. EXPOSURE: RNA biosignatures compared with cultures for discriminating febrile infants with and without bacterial infections and infants with bacteremia from those without bacterial infections. MAIN OUTCOMES AND MEASURES: Bacterial infection confirmed by culture. Performance of RNA biosignatures was compared with routine laboratory screening tests and Yale Observation Scale (YOS) scores. RESULTS: Of 1883 febrile infants (median age, 37 days; 55.7% boys), RNA biosignatures were measured in 279 randomly selected infants (89 with bacterial infections-including 32 with bacteremia and 15 with urinary tract infections-and 190 without bacterial infections), and 19 afebrile healthy infants. Sixty-six classifier genes were identified that distinguished infants with and without bacterial infections in the test set with 87% (95% CI, 73%-95%) sensitivity and 89% (95% CI, 81%-93%) specificity. Ten classifier genes distinguished infants with bacteremia from those without bacterial infections in the test set with 94% (95% CI, 70%-100%) sensitivity and 95% (95% CI, 88%-98%) specificity. The incremental C statistic for the RNA biosignatures over the YOS score was 0.37 (95% CI, 0.30-0.43). CONCLUSIONS AND RELEVANCE: In this preliminary study, RNA biosignatures were defined to distinguish febrile infants aged 60 days or younger with vs without bacterial infections. Further research with larger populations is needed to refine and validate the estimates of test accuracy and to assess the clinical utility of RNA biosignatures in practice.

ABSTRACT

STUDY OBJECTIVE: We describe presentations and outcomes of children with basilar skull fractures in the emergency department (ED) after blunt head trauma. METHODS: This was a secondary analysis of an observational cohort of children with blunt head trauma. Basilar skull fracture was defined as physical examination signs of basilar skull fracture without basilar skull fracture on computed tomography (CT), or basilar skull fracture on CT regardless of physical examination signs of basilar skull fracture. Other definitions included isolated basilar skull fracture (physical examination signs of basilar skull fracture or basilar skull fracture on CT with no other intracranial injuries on CT) and acute adverse outcomes (death, neurosurgery, intubation for >24 hours, and hospitalization for ≥2 nights with intracranial injury on CT). RESULTS: Of 42,958 patients, 558 (1.3%) had physical examination signs of basilar skull fracture, basilar skull fractures on CT, or both. Of the 525 (94.1%) CT-imaged patients, 162 (30.9%) had basilar skull fracture on CT alone, and 104 (19.8%) had both physical examination signs of basilar skull fracture and basilar skull fracture on CT; 269 patients (51.2%) had intracranial injuries other than basilar skull fracture on CT. Of the 363 (91.7%) CT-imaged patients with physical examination signs of basilar skull fracture, 104 (28.7%) had basilar skull fracture on CT. Of 266 patients with basilar skull fracture on CT, 104 (39.1%) also had physical examination signs of basilar skull fracture. Of the 256 CT-imaged patients who had isolated basilar skull fracture, none had acute adverse outcomes (0%; 95% confidence interval 0% to 1.4%), including none (0%; 95% confidence interval 0% to 6.1%) of 59 with isolated basilar skull fractures on CT. CONCLUSION: Approximately 1% of children with blunt head trauma have physical examination signs of basilar skull fracture or basilar skull fracture on CT. The latter increases the risk of acute adverse outcomes more than physical examination signs of basilar skull fracture. A CT scan is needed to adequately stratify the risk of acute adverse outcomes for these children. Children with isolated basilar skull fractures are at low risk for acute adverse outcomes and, if neurologically normal after CT and observation, are candidates for ED discharge.

ABSTRACT

OBJECTIVE: The objective was to compare the accuracy of the pediatric Glasgow Coma Scale (GCS) score in preverbal children to the standard GCS score in older children for identifying those with traumatic brain injuries (TBIs) after blunt head trauma. METHODS: This was a planned secondary analysis of a large prospective observational multicenter cohort study of children with blunt head trauma. Clinical data were recorded onto case report forms before computed tomography (CT) results or clinical outcomes were known. The total and component GCS scores were assigned by the physician at initial emergency department evaluation. The pediatric GCS was used for children <2 years old and the standard GCS for those ≥2 years old. Outcomes were TBI visible on CT and clinically important TBI (ciTBI), defined as death from TBI, neurosurgery, intubation for more than 24 hours for the head injury, or hospitalization for 2 or more nights for the head injury in association with TBI on CT. We compared the areas under the receiver operating characteristic (ROC) curves between age cohorts for the association of GCS and the TBI outcomes. RESULTS: We enrolled 42,041 patients, of whom 10,499 (25.0%) were <2 years old. Among patients <2 years, 313/3,329 (9.4%, 95% confidence interval [CI] = 8.4% to 10.4%) of those imaged had TBIs on CT and 146/10,499 (1.4%, 95% CI = 1.2% to 1.6%) had ciTBIs. In patients ≥2 years, 773/11,977 (6.5%, 95% CI = 6.0% to 6.9%) of those imaged had TBIs on CT and 572/31,542 (1.8%, 95% CI = 1.7% to 2.0%) had ciTBIs. For the pediatric GCS in children <2 years old, the area under the ROC curve was 0.61 (95% CI = 0.59 to 0.64) for TBI on CT and 0.77 (95% CI = 0.73 to 0.81) for ciTBI. For the standard GCS in older children, the area under the ROC curve was 0.71 (95% CI = 0.70 to 0.73) for TBI on CT scan and 0.81 (95% CI = 0.79 to 0.83) for ciTBI. CONCLUSIONS: The pediatric GCS for preverbal children was somewhat less accurate than the standard GCS for older children in identifying those with TBI on CT. However, the pediatric GCS for preverbal children and the standard GCS for older children were equally accurate for identifying ciTBI.

ABSTRACT

OBJECTIVE: Children with minor head trauma frequently present to emergency departments (EDs). Identifying those with traumatic brain injuries (TBIs) can be difficult, and it is unknown whether clinical prediction rules outperform clinician suspicion. Our primary objective was to compare the test characteristics of the Pediatric Emergency Care Applied Research Network (PECARN) TBI prediction rules to clinician suspicion for identifying children with clinically important TBIs (ciTBIs) after minor blunt head trauma. Our secondary objective was to determine the reasons for obtaining computed tomography (CT) scans when clinical suspicion of ciTBI was low. METHODS: This was a planned secondary analysis of a previously conducted observational cohort study conducted in PECARN to derive and validate clinical prediction rules for ciTBI among children with minor blunt head trauma in 25 PECARN EDs. Clinicians recorded their suspicion of ciTBI before CT as <1, 1-5, 6-10, 11-50, or >50%. We defined ciTBI as 1) death from TBI, 2) neurosurgery, 3) intubation for more than 24 hours for TBI, or 4) hospital admission of 2 nights or more associated with TBI on CT. To avoid overfitting of the prediction rules, we performed comparisons of the prediction rules and clinician suspicion on the validation group only. On the validation group, we compared the test accuracies of clinician suspicion > 1% versus having at least one predictor in the PECARN TBI age-specific prediction rules for identifying children with ciTBIs (one rule for children <2 years [preverbal], the other rule for children >2 years [verbal]). RESULTS: In the parent study, we enrolled 8,627 children to validate the prediction rules, after enrolling 33,785 children to derive the prediction rules. In the validation group, clinician suspicion of ciTBI was recorded in 8,496/8,627 (98.5%) patients, and 87 (1.0%) had ciTBIs. CT scans were obtained in 2,857 (33.6%) patients in the validation group for whom clinician suspicion of ciTBI was recorded, including 2,099/7,688 (27.3%) of those with clinician suspicion of ciTBI of <1% and 758/808 (93.8%) of those with clinician suspicion >1%. The PECARN prediction rules were significantly more sensitive than clinician suspicion >1% of ciTBI for preverbal (100% [95% confidence interval {CI} = 86.3% to 100%] vs. 60.0% [95% CI = 38.7% to 78.9%]) and verbal children (96.8% [95% CI = 88.8% to 99.6%] vs. 64.5% [95% CI = 51.3% to 76.3%]). Prediction rule specificity, however, was lower than clinician suspicion >1% for preverbal children (53.6% [95% CI = 51.5% to 55.7%] vs. 92.4% [95% CI = 91.2% to 93.5%]) and verbal children (58.2% [95% CI = 56.9% to 59.4%] vs. 90.6% [95% CI = 89.8% to 91.3%]). Of the 7,688 patients in the validation group with clinician suspicion recorded as <1%, CTs were nevertheless obtained in 2,099 (27.3%). Three of 16 (18.8%) patients undergoing neurosurgery had clinician suspicion of ciTBI <1%. CONCLUSIONS: The PECARN TBI prediction rules had substantially greater sensitivity, but lower specificity, than clinician suspicion of ciTBI for children with minor blunt head trauma. Because CT ordering did not follow clinician suspicion of <1%, these prediction rules can augment clinician judgment and help obviate CT ordering for children at very low risk of ciTBI.

ABSTRACT

Prehospital dosing errors affect approximately 56,000 US children yearly. To decrease these errors, barriers, enablers and solutions from the paramedic (EMT-P) and medical director (MD) standpoint need to be understood. We conducted a mixed-methods study of EMT-P and MDs in Michigan utilizing focus groups (FG). FGs were held at EMS agencies and state EMS conferences. Questions focused on the drug dose delivery process, barriers and enablers to correct dosing and possible solutions to decrease errors. Responses were coded by the research team for themes and number of response mentions. Participants completed a pre-FG survey on pediatric experience and agency characteristics. There were 35 EMT-P and 9 MD participants: 43% of EMT-Ps had been practicing > 10 years, 11% had been practicing < 1 year; and 25% reported they had not administered a drug dose to a child in the last 12 months. EMT-Ps who were "very comfortable" with their ability to administer a correct drug dose to infants, toddlers, school-aged, and adolescents were: 5%, 7%, 10%, and 54%, respectively. FGs identified themes of: difficulty obtaining weight, infrequent pediatric encounters, infrequent/inadequate pediatric training, difficulties with drug packaging, drug bags that were not "EMS friendly," difficulty with drug calculations, and lack of dosing aids. Simplification of dose delivery, an improved length based tape for EMS, pediatric checklists, and dose cards in mL were given as solutions. This mixed-methods study identified barriers and potential solutions to reducing prehospital pediatric drug dosing errors. Solutions should be thoroughly tested prior to implementation.
