Effect of a Sepsis Screening Algorithm on Care of Children with False-Positive Sepsis Alerts.

OBJECTIVES: To determine if implementation of an automated sepsis screening algorithm with low positive predictive value led to inappropriate resource utilization in emergency department (ED) patients as evidenced by an increased proportion of children with false-positive sepsis screens receiving intravenous (IV) antibiotics. STUDY DESIGN: Retrospective cohort study comparing children <18 years of age presenting to an ED who triggered a false-positive sepsis alert during 2 different 5-month time periods: a silent alert period when alerts were generated but not visible to clinicians and an active alert period when alerts were visible. Primary outcome was the proportion of patients who received IV antibiotics. Secondary outcomes included proportion receiving IV fluid boluses, proportion admitted to the hospital, and ED length of stay (LOS). RESULTS: Of 1457 patients, 1277 triggered a false-positive sepsis alert in the silent and active alert periods, respectively. In multivariable models, there were no changes in the proportion administered IV antibiotics (27.0% vs 27.6%, aOR 1.1 [0.9,1.3]) or IV fluid boluses (29.7% vs 29.1%, aOR 1.0 [0.8,1.2]). Differences in ED LOS and proportion admitted to the hospital were not significant when controlling for similar changes seen across all ED encounters. CONCLUSIONS: An automated sepsis screening algorithm did not lead to changes in the proportion receiving IV antibiotics or IV fluid boluses, department LOS, or the proportion admitted to the hospital for patients with false-positive sepsis alerts.

Outcomes of Patients with Sepsis in a Pediatric Emergency Department after Automated Sepsis Screening.

OBJECTIVE: To determine the effect of an automated sepsis screening tool on treatment and outcomes of severe sepsis in a pediatric emergency department (ED). STUDY DESIGN: Retrospective cohort study of encounters of patients with severe sepsis in a pediatric ED with a high volume of pediatric sepsis cases over a 2-year period. The automated sepsis screening algorithm replaced a manual screen 1 year into the study. The primary outcome was the proportion of patients treated for sepsis while in the ED. Secondary outcomes were time from ED arrival to first intravenous (IV) antibiotic and first IV fluid bolus, volume of fluid administered in the ED, 30-day mortality, intensive care unit-free days, and hospital-free days. RESULTS: In year 1 of the study, 8910 of 61 026 (14.6%) of encounters had a manual sepsis screen; 137 patients met criteria for severe sepsis. In year 2, 100% of 61 195 encounters had an automated sepsis screen and there were 136 cases of severe sepsis. There was a higher proportion of patients with severe sepsis who had an active malignancy and indwelling central venous catheter in year 2. There were no differences in the proportion of patients treated for sepsis in the ED, time to first IV antibiotic or first IV fluid bolus, fluid volume delivered in the ED, hospital-free days, intensive care unit-free days, or 30-day mortality after implementation of the automated screening algorithm. CONCLUSIONS: An automated sepsis screening algorithm introduced into an academic pediatric ED with a high volume of sepsis cases did not lead to improvements in treatment or outcomes of severe sepsis in this study.

A single institutional review of pediatric Bacillus spp. bloodstream infections demonstrates increased incidence among children with cancer.

BACKGROUND: Bacillus species are known to cause severe infection in immunocompromised hosts. The incidence of Bacillus bloodstream infections and characteristics of infection among children with cancer or indication for hematopoietic cell transplant (HCT) is unknown. METHODS: We performed a retrospective medical record review of all cases of Bacillus bacteremia between January 1, 2005, and December 31, 2014, at Boston Children's Hospital. We report average incidences from 2012 to 2014. We performed a detailed review of infections among children with cancer or undergoing HCT and a case-control study to evaluate whether neutropenia at diagnosis caries higher risk of Bacillus infection for children with acute lymphoblastic leukemia (ALL). RESULTS: One hundred fourteen children developed Bacillus bacteremia during the study period, with an estimated incidence of 0.27/1,000 patients. Among children treated for cancer or undergoing HCT, there were 37 bloodstream infections (2.0/1,000 patients). Of the 37 oncology/HCT patients, oncologic diagnoses included ALL (18), acute myeloid leukemia (3), myelodysplastic syndrome (1), solid tumors (8), and 7 children were undergoing HCT. The incidence of infection among children with ALL was 34/1,000 patients and all central nervous system (CNS) infections (6) and deaths (3) occurred in this population. Neutropenia at time of diagnosis in children with ALL was not associated with risk of infection (P = 0.17). DISCUSSION: We report the first hospital-wide analysis of Bacillus infection and found that immunocompromised children experience a significant proportion of Bacillus infections. Children with ALL have a high incidence of infection and are at higher risk of CNS involvement and death.

Etiologies and Yield of Diagnostic Testing in Children Presenting to the Emergency Department with Altered Mental Status.

OBJECTIVES: To identify etiologies of altered mental status in pediatric patients presenting to the emergency department (ED) and to characterize the yield of diagnostic testing in these patients. STUDY DESIGN: Retrospective chart review of children aged 1-17 years presenting to a pediatric tertiary care ED between December 31, 2013 and December 31, 2014 with a chief complaint or International Classification of Disease, Ninth Edition code of altered mental status. The primary outcome was the etiology, defined as "immediate diagnosis" if the etiology was known in triage, "definitely established" if established by physical examination and abnormal laboratory results, imaging, or electrocardiogram findings, "probable" if the etiology was highly suspected in the ED but not confirmed with positive test results, or "unknown." The secondary outcome was testing utilization and contribution to the diagnosis. RESULTS: Three hundred thirty-six eligible subjects were identified; mean age of 9 years (±6 years). The etiology of altered mental status was immediately established in 114 subjects (34%, 95% CI 29, 39). Among the remaining eligible subjects (N = 222), a definite or probable cause of altered mental status was identified in 82% (N = 182, 95% CI 76, 86) of cases and the etiology remained "unknown" in 18% (N = 40, 95% CI 14, 24). Only 10% of diagnostic tests performed were abnormal and contributed to a diagnosis. The median number of diagnostic tests per patient was 6 (IQR 3, 8). CONCLUSIONS: Etiologies of altered mental status in children varied widely and often an underlying diagnosis was not found. Broad diagnostic testing was commonly performed although the overall yield was low.

Detecting unapproved abbreviations in the electronic medical record.

BACKGROUND: At an emergency department (ED) in a tertiary care children's hospital with a level 1 pediatric trauma designation, unapproved abbreviations (UAAs) within electronic medical records (EMRs) were identified, and feedback was provided to providers regarding their types and use rates. METHODS: Existing EMRs, including the ED physicians' patient notes were used as templates to develop a UAA list and an abbreviation detector. The detector was validated against human-screened samples of electronic ED notes from 2003 and then applied to all existing data to generate baseline rates of UAA, before intervention/implementation. Next, the validated abbreviation detector was applied prospectively in screening all EMRs monthly during a six-month period. RESULTS: In validation, the abbreviation detector had a sensitivity of 89%, a specificity of 99.9%, and a positive predictive value of 89%. Some 475,613 EMRs were screened, with UAAs identified at a rate of 26.4 +/- 4 per 1,000 EMRs. The most common nonmedication UAA was "qd" [11.8/1,000 EMRs], and the most common medication UAA was "PCN" [4.2/1,000 EMRs]. A total of 27,282 patient notes from 74 physicians were screened between January 1, 2007, and June 30, 2007, and 392 monthly reports were generated. Aggregate UAA use decreased by 8% (95% confidence interval [CI]: 6%-14%) per month-from 19.3 to > 12.1/100 charts, for a 37.3% decrease in UAA use in the six-month period. The estimated monthly decrease per physician was 0.9/100 (95% CI: 0.86-0.94, p < .001.) After adjusting for secular trends, the decrease was 29% in the six-month study period (95% CI: 14%-44%, p < .0001). CONCLUSIONS: Use of the abbreviation detector for surveillance of newly created EMRs, followed by consistent education and feedback, led to a significant decrease in UAA use in the study period.

Yield of emergent neuroimaging among children presenting with a first complex febrile seizure.

OBJECTIVES: The objective of this study was to assess the risk of intracranial pathology requiring immediate intervention among children presenting with their first complex febrile seizure (CFS). DESIGN/METHODS: This is a retrospective cohort review of patients 6 to 60 months of age evaluated in a pediatric emergency department between 1995 and 2008 for their first CFS. Cases were identified using computerized text search followed by manual chart review. We excluded patients with a prior history of a nonfebrile seizure disorder or a prior CFS, an immune-compromised state, an underlying illness associated with seizures or altered mental status, or trauma. Data extraction included age, sex, seizure features, prior simple febrile seizures, temperature, family history of seizures, vaccination status, findings on physical examination, laboratory and imaging studies, diagnosis, and disposition. RESULTS: We identified a first CFS in 526 patients. Two hundred sixty-eight patients (50.4%) had emergent head imaging: 4 patients had a clinically significant finding: 2 had intracranial hemorrhage, 1 had acute disseminated encephalomyelitis, and 1 patient had focal cerebral edema (1.5%; 95% confidence interval, 0.5%-4.0%). Assigning low risk to patients not imaged and not returning to the emergency department within a week of the original visit, the risk of intracranial pathology in our sample was 4 (0.8%; 95% confidence interval, 0.2%-2.1%) of 526. Three of these 4 patients had other obvious findings (nystagmus, emesis, and altered mental status; persistent hemiparesis; bruises suggestive of inflicted injury). CONCLUSIONS: Very few patients with CFSs have intracranial pathology in the absence of other signs or symptoms. Patients presenting with more than one seizure in 24 hours in particular are at very low risk.

Pediatric Emergency Department Sepsis Screening Tool Accuracy During the COVID-19 Pandemic.

BACKGROUND: Automated sepsis alerts in pediatric emergency departments (EDs) can identify patients at risk for sepsis, allowing for earlier intervention with appropriate therapies. The impact of the COVID-19 pandemic on the performance of pediatric sepsis alerts is unknown. METHODS: We performed a retrospective cohort study of 59 335 ED visits before the pandemic and 51 990 ED visits during the pandemic in an ED with an automated sepsis alert based on systemic inflammatory response syndrome criteria. The sensitivity, specificity, negative predictive value, and positive predictive value of the sepsis algorithm were compared between the prepandemic and pandemic phases and between COVID-19-negative and COVID-19-positive patients during the pandemic phase. RESULTS: The proportion of ED visits triggering a sepsis alert was 7.0% (n = 4180) before and 6.1% (n = 3199) during the pandemic. The number of sepsis alerts triggered per diagnosed case of hypotensive septic shock was 24 in both periods. There was no difference in the sensitivity (74.1% vs 72.5%), specificity (93.2% vs 94.0%), positive predictive value (4.1% vs 4.1%), or negative predictive value (99.9% vs 99.9%) of the sepsis alerts between these periods. The alerts had a lower sensitivity (60% vs 73.3%) and specificity (87.3% vs 94.2%) for COVID-19-positive versus COVID-19-negative patients. CONCLUSIONS: The sepsis alert algorithm evaluated in this study did not result in excess notifications and maintained adequate performance during the COVID-19 pandemic in the pediatric ED setting.

Comparison of Manual and Automated Sepsis Screening Tools in a Pediatric Emergency Department.

OBJECTIVES: To compare the performance and test characteristics of an automated sepsis screening tool with that of a manual sepsis screen in patients presenting to a pediatric emergency department (ED). METHODS: We conducted a retrospective cohort study of encounters in a pediatric ED over a 2-year period. The automated sepsis screening algorithm replaced the manual sepsis screen 1 year into the study. A positive case was defined as development of severe sepsis or septic shock within 24 hours of disposition from the ED. We calculated the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and positive and negative likelihood ratios with 95% confidence intervals (CIs) for each. RESULTS: There were 122 221 ED encounters during the study period and 273 cases of severe sepsis. During year 1 of the study, the manual screen was performed in 8910 of 61 026 (14.6%) encounters, resulting in the following test characteristics: sensitivity of 64.6% (95% CI 54.2%-74.1%), specificity of 91.1% (95% CI 90.5%-91.7%), PPV of 7.3% (95% CI 6.3%-8.5%), and NPV of 99.6% (95% CI 99.5%-99.7%). During year 2 of the study, the automated screen was performed in 100% of 61 195 encounters, resulting in the following test characteristics: sensitivity of 84.6% (95% CI 77.4%-90.2%), specificity of 95.1% (95% CI 94.9%-95.2%), PPV of 3.7% (95% CI 3.4%-4%), and NPV of 99.9% (95% CI 99.9%-100%). CONCLUSIONS: An automated sepsis screening algorithm had higher sensitivity and specificity than a widely used manual sepsis screen and was performed on 100% of patients in the ED, ensuring continuous sepsis surveillance throughout the ED stay.

Prediction of patient disposition: comparison of computer and human approaches and a proposed synthesis.

OBJECTIVE: To compare the accuracy of computer versus physician predictions of hospitalization and to explore the potential synergies of hybrid physician-computer models. MATERIALS AND METHODS: A single-center prospective observational study in a tertiary pediatric hospital in Boston, Massachusetts, United States. Nine emergency department (ED) attending physicians participated in the study. Physicians predicted the likelihood of admission for patients in the ED whose hospitalization disposition had not yet been decided. In parallel, a random-forest computer model was developed to predict hospitalizations from the ED, based on data available within the first hour of the ED encounter. The model was tested on the same cohort of patients evaluated by the participating physicians. RESULTS: 198 pediatric patients were considered for inclusion. Six patients were excluded due to incomplete or erroneous physician forms. Of the 192 included patients, 54 (28%) were admitted and 138 (72%) were discharged. The positive predictive value for the prediction of admission was 66% for the clinicians, 73% for the computer model, and 86% for a hybrid model combining the two. To predict admission, physicians relied more heavily on the clinical appearance of the patient, while the computer model relied more heavily on technical data-driven features, such as the rate of prior admissions or distance traveled to hospital. DISCUSSION: Computer-generated predictions of patient disposition were more accurate than clinician-generated predictions. A hybrid prediction model improved accuracy over both individual predictions, highlighting the complementary and synergistic effects of both approaches. CONCLUSION: The integration of computer and clinician predictions can yield improved predictive performance.

Occurrence of metabolic acidosis in pediatric emergency department patients as a data source for disease surveillance systems.

BACKGROUND: We hypothesize that the occurrence of metabolic acidosis correlates with the cumulative rate of gastrointestinal (GI) illness and that incorporating acidosis surveillance would improve models used for the early detection of outbreaks of GI disease. METHODS: We conducted a retrospective cohort study of consecutive patients seen in an urban pediatric tertiary care center from September 1995 to August 2005. All data were analyzed for correlation between acidosis and GI syndrome and for internal periodicities. Four years of data were used to create a model, and the first 100 days of 2004 were used for forecasting. Data collected included visit date, chief complaint (CC), International Classification of Diseases, 9th Revision, diagnoses (Dx), and limited laboratory data. Gastrointestinal syndrome was defined by either CC or Dx. Acidosis was defined as HCO3 levels 19 mmol/dL or less. Exclusion criteria included hyperglycemia (glucose level >120 mg/dL), glycusoria, or having a test for glycosylated hemoglobin ordered. A simple regression model was used to measure correlation between rates of acidosis and GI_Dx and GI_CC. For acidosis and GI syndrome, we fitted a time series model to the daily data with an auto-regressive integrated moving average (1,1) error term. RESULTS: During the study period, there were 505,028 emergency department visits. The median age was 5.1 years (interquartile range, 1.6-11.8 years), and 46% of patients were females. Of these, 132,142 had GI_Dx and 136,304 had GI_CC. Blood chemistries were obtained from 91,052 patients (18.1%). Acidosis was detected in 32.4% of patients who had these laboratory tests sent.Periodicities were detected for GI_Dx, GI_CC, acidosis rates affected by day of the week, and seasonality, with no changes in incidence during the years of our study. Acidosis rates highly correlated with rates of GI syndrome on a daily basis (Pearson correlation coefficient, r = 0.66 for GI_Dx and r = 0.68 for GI_CC, P < 0.0001 for both). Having non-diabetic ketoacidosis metabolic acidosis has a 42.2% positive predictive value for GI syndrome by either Dx or CC.Acidosis rates can be forecasted as a stand-alone variable (R² = 0.31, P < 0.001).Adding acidosis rates to time series models for GI_Dx or GI_CC significantly improves forecasting, that is, GI_Dx improved from R² = 0.24 to R² = 0.54, and false alarms rates dropped from 32% to 18%. The GI_CC model improved from R² = 0.32 to R = 0.54, and false alarms rates dropped from 28% to 17%. CONCLUSIONS: Metabolic acidosis rate is a promising data source for real-time disease surveillance in the pediatric population. The rate of metabolic acidosis is highly correlated with the rate of GI syndrome. Adding this variable to currently used models significantly improves forecasting for real-time surveillance.

Holiday ornament-related injuries in children.

OBJECTIVES: Holiday ornament injuries in children have not been well documented in the medical literature. Our aim was to investigate the patterns of injuries sustained from these ornaments as a first measure toward prevention. METHODS: This was a retrospective cohort analysis of all patients examined in an urban pediatric emergency department over a 13-year period ending in March 2008 for holiday ornament-related injuries. Cases were identified using a computer-assisted text query followed by a manual chart review. Data collected from each chart included the child's age, sex, injury characteristics, physical examination findings, radiographic imaging, interventions, and disposition. To analyze injury rates over the years, we used a multiplicative Poisson model allowing varying exposures. RESULTS: Over the study period, we identified 76 eligible patients. The median age was 2 years (interquartile range, 1.17-3.3 years); 44.7% were female. Forty-three of the 76 cases (53.9%) involved ingestions: 35 were of holiday ornaments, and 8 were of light bulbs. All but one of these ornaments were made of glass. In 28%, there was an associated bleed either from the mouth or as a delayed gastrointestinal bleed. Other patients experienced lacerations (27.6%), eye injuries (5.1%), and minor electrocution injury (2.5%). Imaging was performed in 85%. A subspecialty consult was obtained in 23%, primarily addressing a foreign body ingestion or removal after skin exploration. The incidence rate has not changed over the years. CONCLUSIONS: Holiday ornament-related injuries primarily involve foreign body ingestions and glass-related injuries. Over half of the injuries involved small light bulbs and ornaments made of glass placed at the level a toddler can reach. Pediatricians are advised to discuss these points with families during holiday season.

Focal motor seizure in a wrestler with a sport-related concussion.

UNLABELLED: Although sport-related concussion is a common injury, it is infrequently associated with seizure. While concussive convulsions, consisting of brief, generalized myoclonic activity while an athlete is unconscious have been described, the authors are aware of no published cases of concussion complicated by focal motor seizures. The authors describe the case of a 16-year-old male wrestler who sustained a sport-related concussion complicated by a focal motor seizure. The acute assessment and management of his injury, as well as follow-up until resolution of his symptoms, is presented. A brief review of the association between convulsive activity and mild traumatic brain injury follows. KEYWORDS: concussion; mild traumatic brain injury; seizure.

The effect of an electronic health record-based tool on abnormal pediatric blood pressure recognition.

BACKGROUND: Recognition of high blood pressure (BP) in children is poor, partly due to the need to compute age-sex-height referenced percentiles. This study examined the change in abnormal BP recognition before versus after the introduction of an electronic health record (EHR) app designed to calculate BP percentiles with a training lecture. METHODS AND RESULTS: Clinical data were extracted on all ambulatory, non-urgent encounters for children 3-18 years old seen in primary care, endocrinology, cardiology, or nephrology clinics at an urban, academic hospital in the year before and the year after app introduction. Outpatients with at least 1 BP above the age-gender-height referenced 90th percentile were included. Abnormal BP recognition was defined as a BP related ICD-9 code, referral to nephrology or cardiology, an echocardiogram or renal ultrasound to evaluate BP concern, or a follow-up primary care visit for BP monitoring. Multivariable adjusted logistic regression compared odds of recognition before and after app introduction. Of 78 768 clinical encounters, 3521 had abnormal BP in the pre- and 3358 in the post-app period. App use occurred in 13% of elevated BP visits. Overall, abnormal BP was recognized in 4.9% pre-app period visits and 7.1% of visits post-app (P < .0001). Recognition was significantly higher when the app was actually used (adjusted OR 3.17 95% CI 2.29-4.41, P < .001). Without app use recognition was not different. CONCLUSIONS: BP app advent modestly increased abnormal BP recognition in the entire cohort, but actual app use was associated with significantly higher recognition. Predictors of abnormal BP recognition deserve further scrutiny.

The use of routine laboratory studies as screening tools in pediatric abdominal trauma.

BACKGROUND: Standard laboratory panels were shown to play an important role in the evaluation of pediatric blunt abdominal trauma before the routine use of computed tomography (CT) scan. Recently, only a few relatively limited studies have evaluated the use of these "trauma panels." OBJECTIVE: To evaluate the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of routine "trauma panels" for evaluating intra-abdominal injury in pediatric blunt trauma patients. METHOD: We undertook a retrospective medical record review of all children with potential major blunt abdominal trauma who entered the Children's Hospital (Boston, MA) trauma registry from July 1996 to August 1999. Routine laboratory tests during those years included sodium, glucose, white blood cell count, hematocrit, platelets, prothrombin time, activated partial thromboplastin time, aspartate aminotransferase (AST), alanine aminotransferase, amylase, lipase, and urinalysis. Individual findings were considered abnormal if they fell out of the laboratory's respective reference range. We determined sensitivity, specificity, PPV, NPV, and the 95% confidence interval for each test, using abdominal pathology identified by CT scan as the gold standard. RESULTS: Three hundred eighty-two patients were included. Of that, 68% were men. Median age was 115 months (intraquartile range, 60-159 months). In total, 241 of the patients (63%) had an abdominal CT scan performed, 83 of which (33%) had abnormal findings. Abnormal values for glucose, AST, urinalysis, and white blood cell count were the most frequently observed abnormalities (67%, 47%, 43%, and 43%, respectively). Among the 83 patients with abdominal pathology, glucose and AST had the highest sensitivity (75% and 63%, respectively). Lipase had the highest PPV at 75%, and AST had the highest negative predictive at 71%. No routine laboratory test had excellent sensitivity, specificity, PPV, and NPV. CONCLUSIONS: Routine "trauma panels" should not be obtained as a screening tool in children with blunt trauma being evaluated for intra-abdominal injury.

Improving adherence to PALS septic shock guidelines.

BACKGROUND AND OBJECTIVES: Few studies have demonstrated improvement in adherence to Pediatric Advanced Life Support guidelines for severe sepsis and septic shock. We sought to improve adherence to national guidelines for children with septic shock in a pediatric emergency department with poor guideline adherence. METHODS: Prospective cohort study of children presenting to a tertiary care pediatric emergency department with septic shock. Quality improvement (QI) interventions, including repeated plan-do-study-act cycles, were used to improve adherence to a 5-component sepsis bundle, including timely (1) recognition of septic shock, (2) vascular access, (3) administration of intravenous (IV) fluid, (4) antibiotics, and (5) vasoactive agents. The intervention focused on IV fluid delivery as a key driver impacting bundle adherence, and adherence was measured using statistical process control methodology. RESULTS: Two-hundred forty-two patients were included: 126 subjects before the intervention (November 2009 to March 2011), and 116 patients during the QI intervention (October 2011 to May 2013). We achieved 100% adherence for all metrics, including (1) administration of 60 mL/kg IV fluid within 60 minutes (increased from baseline adherence rate of 37%), (2) administration of vasoactive agents within 60 minutes (baseline rate of 35%), and (3) 5-component bundle adherence (baseline rate of 19%). Improvement was sustained over 9 months. The number of septic shock cases between each death from this condition increased after implementation of the QI intervention. CONCLUSIONS: Using QI methodology, we have demonstrated improved adherence to national guidelines for severe sepsis and septic shock.

Yield of lumbar puncture among children who present with their first complex febrile seizure.

OBJECTIVE: To assess the rate of acute bacterial meningitis (ABM) among children who present with their first complex febrile seizure (CFS). DESIGN AND METHODS: This study was a retrospective, cohort review of patients aged 6 to 60 months who were evaluated in a pediatric emergency department (ED) between 1995 and 2008 for their first CFS. Cases were identified by using a computerized text search followed by a manual chart review. Exclusion criteria included prior history of nonfebrile seizures, an immunocompromised state, an underlying illness associated with seizures or altered mental status, or trauma. Data extracted included age, gender, seizure features, the number of previous simple febrile seizures, temperature, a family history of seizures, findings on physical examination, laboratory and imaging study results, and ED diagnosis and disposition. RESULTS: We identified 526 patients. The median age was 17 months (interquartile range: 13-24), and 44% were female. Ninety patients (17%) had a previous history of simple febrile seizures. Of the patients, 340 (64%) had a lumbar puncture (LP). The patients' median white blood cell count during a CFS was 1 cell per microL (interquartile range: 1-2), and 14 patients had CSF pleocytosis (2.7% [95% confidence interval [CI]: 1.5-4.5]). Three patients had ABM (0.9% [95% CI: 0.2-2.8]). Two had Streptococcus pneumoniae in a culture of their cerebrospinal fluid. Among these 2 patients, 1 was nonresponsive during presentation, and the other had a bulging fontanel and apnea. The third child appeared well; however, her blood culture grew S pneumoniae and failed the LP test. None of the patients for whom an LP was not attempted subsequently returned to the hospital with a diagnosis of ABM (0% [95% CI: 0, 0.9]). CONCLUSION: Few patients who experienced a CFS had ABM in the absence of other signs or symptoms.

Utility of lumbar puncture for first simple febrile seizure among children 6 to 18 months of age.

OBJECTIVES: American Academy of Pediatrics consensus statement recommendations are to consider strongly for infants 6 to 12 months of age with a first simple febrile seizure and to consider for children 12 to 18 months of age with a first simple febrile seizure lumbar puncture for cerebrospinal fluid analysis. Our aims were to determine compliance with these recommendations and to assess the rate of bacterial meningitis detected among these children. METHODS: A retrospective cohort review was performed for patients 6 to 18 months of age who were evaluated for first simple febrile seizure in a pediatric emergency department between October 1995 and October 2006. RESULTS: First simple febrile seizure accounted for 1% of all emergency department visits for children of this age, with 704 cases among 71 234 eligible visits during the study period. Twenty-seven percent (n = 188) of first simple febrile seizure visits were for infants 6 to 12 months of age, and 73% (n = 516) were for infants 12 to 18 months of age. Lumbar puncture was performed for 38% of the children (n = 271). Samples were available for 70% of children 6 to 12 months of age (131 of 188 children) and 25% of children 12 to 18 months of age (129 of 516 children). Rates of lumbar puncture decreased significantly over time in both age groups. The cerebrospinal fluid white blood cell count was elevated in 10 cases (3.8%). No pathogen was identified in cerebrospinal fluid cultures. Ten cultures (3.8%) yielded a contaminant. No patient was diagnosed as having bacterial meningitis. CONCLUSIONS: The risk of bacterial meningitis presenting as first simple febrile seizure at ages 6 to 18 months is very low. Current American Academy of Pediatrics recommendations should be reconsidered.

Reforming procedural skills training for pediatric residents: a randomized, interventional trial.

BACKGROUND: Pediatric housestaff are required to learn basic procedural skills and demonstrate competence during training. To our knowledge, an evidenced-based procedural skills curriculum does not exist. OBJECTIVE: To create, implement, and evaluate a modular procedural skills curriculum for pediatric residents. METHODS: A randomized, controlled trial was performed. Thirty-eight interns in the Boston Combined Residency Program who began their training in 2005 were enrolled and randomly assigned. Modules were created to teach residents bag-mask ventilation, venipuncture, peripheral intravenous catheter (PIV) insertion, and lumbar puncture skills. The curriculum was administered to participants in the intervention group during intern orientation. Interns in the control group learned procedural skills by usual methods. Subjects were evaluated by using a structured objective assessment on simulators immediately after the intervention and 7 months later. Success in performing live-patient procedures was self-reported by subjects. The primary outcome was successful performance of the procedure on the initial assessment. Secondary outcomes included checklist and knowledge examination scores, live-patient success, and qualitative assessment of the curriculum. RESULTS: Participants in the intervention group performed PIV placement more successfully than controls (79% vs 35%) and scored significantly higher on the checklist for PIV placement (81% vs 61%) and lumbar puncture (77% vs 68%) at the initial assessment. There were no differences between groups at month 7, and both groups demonstrated declining skills. There were no statistically significant differences in success on live-patient procedures. Those in the intervention group scored significantly higher on knowledge examinations. CONCLUSIONS: Participants in the intervention group were more successful performing certain simulated procedures than controls when tested immediately after receiving the curriculum but demonstrated declining skills thereafter. Future efforts must emphasize retraining, and residents must have sufficient opportunities to practice skills learned in a formal curriculum.
