RESUMO
BACKGROUND: Invasive bacterial infections (IBIs) in febrile infants are rare but potentially devastating. We aimed to derive and validate a predictive model for IBI among febrile infants age 7-60 days. METHODS: Data were abstracted retrospectively from electronic records of 37 emergency departments (EDs) for infants with a measured temperature >=100.4 F who underwent an ED evaluation with blood and urine cultures. Models to predict IBI were developed and validated respectively using a random 80/20 dataset split, including 10-fold cross-validation. We used precision recall curves as the classification metric. RESULTS: Of 4411 eligible infants with a mean age of 37 days, 29% had characteristics that would likely have excluded them from existing risk stratification protocols. There were 196 patients with IBI (4.4%), including 43 (1.0%) with bacterial meningitis. Analytic approaches varied in performance characteristics (precision recall range 0.04-0.29, area under the curve range 0.5-0.84), with the XGBoost model demonstrating the best performance (0.29, 0.84). The five most important variables were serum white blood count, maximum temperature, absolute neutrophil count, absolute band count, and age in days. CONCLUSION: A machine learning model (XGBoost) demonstrated the best performance in predicting a rare outcome among febrile infants, including those excluded from existing algorithms. IMPACT: Several models for the risk stratification of febrile infants have been developed. There is a need for a preferred comprehensive model free from limitations and algorithm exclusions that accurately predicts IBIs. This is the first study to derive an all-inclusive predictive model for febrile infants aged 7-60 days in a community ED sample with IBI as a primary outcome. This machine learning model demonstrates potential for clinical utility in predicting IBI.
RESUMO
Introduction There is considerable variation in the approach to infants presenting to the emergency department (ED) with fever. The authors' primary aim was to develop a robust set of algorithms using community ED data to inform modifications of broader clinical guidance. Methods The authors report the development of California Febrile Infant Risk Stratification Tool (CA FIRST) using key components of the Roseville Protocol (ROS) and American Academy of Pediatrics (AAP) Clinical Practice Guideline (CPG). Expanded guidance was derived using a retrospective analysis of a cohort of 3527 febrile infants aged 7-90 days presenting to any Kaiser Permanente Northern California ED between 2010 and 2019 who underwent a core febrile infant evaluation. Results Melding ROS and AAP CPG algorithms in infants 7-60 days old, CA FIRST Algorithms had comparable performance characteristics to ROS and AAP CPG. CA FIRST enhancements included guidance on febrile infants 61-90 days old, high-risk infants, infants with bronchiolitis, and infants who received immunizations within the prior 48 hours. This retrospective analysis revealed that of 235 febrile infants 22-90 days old with respiratory syncytial virus and 221 who had fever in the 48 hours following vaccination, there were no cases of invasive bacterial infection. Discussion CA FIRST is a set of 13 algorithms providing a thoughtful and flexible approach to the febrile infant while minimizing unnecessary interventions. Conclusions CA FIRST Algorithms empower clinicians to manage most febrile infants. Algorithms are being modified as new data become available, imparting useful and ever-current educational information within a learning health care system.

BACKGROUND AND OBJECTIVES: In 2021, the American Academy of Pediatrics (AAP) published the Clinical Practice Guideline (CPG) for management of well-appearing, febrile infants 8 to 60 days old. For older infants, the guideline relies on several inflammatory markers, including tests not rapidly available in many settings like C-reactive protein (CRP) and procalcitonin (PCT). This study describes the performance of the AAP CPG for detecting invasive bacterial infections (IBI) without using CRP and PCT. METHODS: This retrospective cohort study included infants aged 8 to 60 days old presenting to Kaiser Permanente Northern California emergency departments between 2010 and 2019 with temperatures ≥38°C who met AAP CPG inclusion criteria and underwent complete blood counts, blood cultures, and urinalyses. Performance characteristics for detecting IBI were calculated for each age group. RESULTS: Among 1433 eligible infants, there were 57 (4.0%) bacteremia and 9 (0.6%) bacterial meningitis cases. Using absolute neutrophil count >5200/mm3 and temperature >38.5°C as inflammatory markers, 3 (5%) infants with IBI were misidentified. Sensitivities and specificities for detecting infants with IBIs in each age group were: 8 to 21 days: 100% (95% confidence interval [CI] 83.9%-100%) and 0% (95% CI 0%-1.4%); 22 to 28 days: 88.9% (95% CI 51.8%-99.7%) and 40.4% (95% CI 33.2%- 48.1%); and 29 to 60 days: 93.3% (95% CI 77.9%-99.2%) and 32.1% (95% CI 29.1%- 35.3%). Invasive interventions were recommended for 100% of infants aged 8 to 21 days; 58% to 100% of infants aged 22 to 28 days; and 0% to 69% of infants aged 29 to 60 days. CONCLUSIONS: When CRP and PCT are not available, the AAP CPG detected IBI in young, febrile infants with high sensitivity but low specificity.
RESUMO
Objective: Describe emergency department (ED) management and patient outcomes for febrile infants 29-60 days of age who received a lumbar puncture (LP), with focus on timing of antibiotics and type of physician performing LP. Methods: Retrospective observational study of 35 California EDs from January 1, 2010 through December 31, 2019. Primary analysis was among patients with successful LP and primary outcome was hospital length of stay (LOS). Logistic regression analysis included variables associated with LOS of at least 2 days. Secondary outcomes were bacterial meningitis, hospital admission, length of antibiotics, and readmission. Results: Among 2569 febrile infants (median age 39 days), 667 underwent successful LP and 633 received intravenous antibiotics. Most infants (n = 559, 88.3%) had their LP before intravenous antibiotic administration. Pediatricians performed 54% of LPs and emergency physicians 34%. Sixteen infants (0.6% of 2569) were diagnosed with bacterial meningitis, and none died. Five hundred and fifty-eight (88%) infants receiving an LP were hospitalized. Among patients receiving an LP and antibiotics (n = 633), 6.5% were readmitted within 30 days. Patients receiving antibiotics before LP had a longer length of antibiotics (+ 7.9 hours, 95% confidence interval [CI] 3.8-13.4). Primary analysis found no association between timing of antibiotics and LOS (odds ratio [OR] 0.67, 95% CI 0.34-1.30), but shorter LOS when emergency physicians performed the LP (OR 0.66, 95% CI 0.45-0.97). Conclusions: Febrile infants in the ED had no deaths and few cases of bacterial meningitis. In community EDs, where a pediatrician is often not available, successful LP by emergency physician was associated with reduced inpatient LOS.
RESUMO
INTRODUCTION: High-flow nasal cannula (HFNC) oxygen therapy is being used in pediatric wards at increasing rates, including community hospitals that do not have a pediatric intensive care unit (PICU). This study describes the use of HFNC in a pediatric ward at a community hospital, evaluating safety, flow limits, and outcomes for children transferred to a PICU. METHODS: A descriptive, single center retrospective cohort study of consecutive subjects from birth to 24 months of age treated with HFNC for bronchiolitis in our pediatric ward from January 2016 to May 2019. We report demographic and clinical characteristics of the patients. The outcomes of interest include episodes of aspiration, pneumothorax, intubation, cardiorespiratory arrest, and transfers to the PICU. RESULTS: There were 157 hospitalizations. One hundred twenty-three children (78.3%) were weaned off HFNC and discharged to home. Flow rates of up to 3 L/kg/min (average, 1.22 L/kg/min; range 0.28-3.08 L/kg/min) were tolerated. Of the 34 children transferred to the PICU, 29 were continued on HFNC, 1 required continuous positive airway pressure, and 4 were intubated. The median time from initiation of HFNC to transfer was 13 hours (interquartile range 6.0-23.0). There were no documented episodes of aspiration, pneumothorax, cardiorespiratory arrest, or death. CONCLUSION: HFNC could be safely administered in a community hospital pediatric ward without PICU expertise and capability. Most patients who deteriorate on HFNC do so within the first 24 hours when close monitoring is needed. For children transferred to a PICU, the vast majority did not require more invasive forms of respiratory support.

OBJECTIVE: Evidence suggests that exposure to opioids in adolescence increases risk of future opioid use. We evaluate if exposure to high versus low intensity opioid prescribers in the Emergency Department (ED) influences the risk of future opioid use in adolescents. METHODS: Retrospective study of opioid-naïve patients 10 to 17 years seen in one of 14 EDs between January 2013 and December 2014. We categorized ED providers into quartiles according to the proportion of encounters resulting in opioid prescriptions. Primary outcome was use of opioids in the subsequent 12 months. Analysis adjusted for patient characteristics and compared future use of opioids for patients seen by the lowest versus the highest prescribing quartiles. RESULTS: We included 9,688 patient encounters evaluated by the lowest opioid prescribing physician quartile versus 9,467 in the highest. The highest quartile gave opioid prescriptions to 14.9% of their patients compared to 2.8% for the lowest quartile. No association with future opioid use was found for patients evaluated by low versus high prescriber quartiles (OR 0.99, 95% CI 0.90-1.08). Patients with increasing age (OR 2.15, 95% CI 1.92-2.42) and white versus Hispanic ethnicity (OR 1.55, 95% CI 1.33-1.80) were associated with recurrent opioid use. CONCLUSION: We found no association between high intensity opioid prescribers and recurrent 12 month use of opioids in opioid-naïve adolescents seen in the ED. This likely reflects various factors that put adolescents at risk for recurrent opioid use and may indicate the importance of the second prescription from primary care after initial exposure to opioids.

OBJECTIVES: Adolescents and young adults are at high risk for opioid misuse and abuse. The emergency department (ED) plays a key role in treatment of acute and chronic pain and is a primary place that this patient population is exposed to prescription opioids. We evaluate the effect of patient age on use of opioids for adolescents and young adults in community EDs. METHODS: Retrospective cohort study of adolescent and young adult encounters in 14 community EDs from 2013 to 2014. We evaluate the percent of ED encounters with parenteral and/or oral opioids administered, morphine milligram equivalents per ED patient encounter, and percent of patient encounters discharged with an opioid prescription. Age was the main exposure. The association between outcomes and age was examined using bivariate and multivariate logistic regression adjusting for measurable confounders. RESULTS: There were 259,632 adolescent and young adult encounters in our sample, average age 17.6â¯years, with 15.8% given opioids. Increasing patient age was associated with a significant increase in the percent of encounters with opioids given (AOR, 1.11; 95% CI 1.10-1.11), morphine milligram equivalents administered (ß 0.38; 95% CI 0.33-0.43 for parenteral and ß 0.26; 95% CI 0.23-0.28 for oral), and percent of patients receiving outpatient prescriptions (AOR, 1.14; 95% CI 1.13-1.14). Significant variability also existed between medical centers (AOR, 2.02; 95% CI 1.86-2.20). CONCLUSION: For adolescent and young adult patients in the ED, there is a significant association between opioid prescribing and increasing age. This describes an opportunity to reduce opioid use in older adolescents and young adults.

CONTEXT: Children with acute lymphoblastic leukemia (ALL) in first complete remission (CR1) experience hypogammaglobulinemia and are at risk of sepsis during maintenance chemotherapy. Intravenous immunoglobulin (IVIG) has been used to try to circumvent this risk, but no data exist regarding its safety and prevalence in a health maintenance organization. OBJECTIVE: To evaluate the prevalence and safety of IVIG in children with ALL in CR1 during maintenance chemotherapy. DESIGN: A multicenter, retrospective cohort study of consecutive children with ALL in CR1 during maintenance chemotherapy from 2008 to 2014. Groups treated with or without IVIG were compared using nonparametric statistics. Multivariate logistic regression involved all variables available before maintenance therapy began. RESULTS: One hundred eighteen patients were included (53% males), aged 9 months to 19 years. Thirty of 31 patients (97%) who had immunoglobulins analyzed before IVIG were hypogammaglobulinemic. Thirty-six patients (30%) received IVIG during maintenance chemotherapy. Patients received an average of 10.5 IVIG doses (range = 1-31). Ninety-seven percent of doses were administered without a transfusion reaction. Other factors associated with IVIG use were prior double-delayed intensification (odds ratio = 5.36, 95% confidence interval = 1.3-27.49, p = 0.026) and episodes of bacteremia or fungemia before maintenance chemotherapy (odds ratio = 3.04, 95% confidence interval = 1.25-7.51, p = 0.015). CONCLUSION: Use of IVIG in children with ALL in CR1 with hypogammaglobulinemia occurred in approximately 30% of patients and was well tolerated. Administration of IVIG significantly correlated with a history of double-delayed intensification and prior bacteremia or fungemia.

OBJECTIVE: Opioid prescribing guidelines are commonly seen as part of the solution to America's opioid epidemic. However, the effectiveness of specific treatment guidelines on altering opioid prescribing in the emergency department (ED) is unclear. We examined provider ordering patterns before and after implementation of opioid use guidelines for ED patients overall and the specific subsets of ED patients with either chronic opioid use or fracture. METHODS: We conducted a pre-post interrupted time series analysis of adult (≥18 years old) ED encounters in 14 integrated community EDs before (2013) and after (2014) the implementation of opioid prescribing guidelines. We compared opioid use pre- and postintervention using segmented logistic regression for primary and secondary analyses. The primary outcome was parenteral opioid use in the ED, with additional subgroup analysis of chronic pain and fracture cohorts. We also examined ED oral opioid use and discharge prescribing. RESULTS: There were 508,337 pre- and 531,620 postintervention encounters. The intervention was associated with an initial reduction in the odds of parenteral opioids ordered (odds ratio [OR] = 0.89, 95% CI = 0.87-0.91) and a decrease in the monthly trend compared to the preintervention period (OR = 0.99, 95% CI = 0.99-0.99). The immediate reduction in parenteral opioid use was significantly larger in the cohort of patients with chronic pain (OR = 0.81, 95% CI = 0.72-0.91), whereas the fracture cohort showed no change (OR = 1.10, 95% CI = 0.97-1.25). CONCLUSION: The use of an opioid ordering guideline was associated with significant reduction in parenteral opioid use in the ED and as intended subgroup comparisons suggest that acute fractures were not affected and chronic pain visits were associated with larger decreases in opioid use.
RESUMO
CONTEXT: Vaccination against the human papillomavirus (HPV) decreases risks of cancer and genital warts and the need for gynecologic procedures, yet nationwide vaccination rates are low. Previous surveys exploring this phenomenon have not included input from nurses and medical assistants, who play integral roles in HPV vaccine delivery. OBJECTIVE: To understand perceptions of HPV vaccine delivery among physicians, nurses, and medical assistants in a large integrated health care system in Southern California. DESIGN: Online surveys were sent to 13 nurse administrators and 75 physicians. Physicians were instructed to forward the survey to nurses and medical assistants with whom they work. RESULTS: A total of 76 surveys were completed, consisting of 52 physicians, 16 clinical nurses and medical assistants, and 8 nurse administrators. Physicians' perceptions of vaccine safety or strength of recommendation did not differ by specialty department. Physicians reportedly perceived the HPV vaccine as safer than did clinical nurses and medical assistants (p < 0.001), who indicated they wanted more education on the safety and efficacy of the vaccine before being comfortable strongly recommending it. Respondents advised that all clinicians could improve in their roles as HPV vaccine advocates through patient counseling and providing informational literature and that workflow standardization was needed to minimize missed vaccination opportunities. CONCLUSION: Physicians reportedly perceive the HPV vaccine as safer compared with nurses and medical assistants. Both groups think that more education of nonphysician staff is needed. Having proper systems in place is also vital to improving vaccination compliance.

OBJECTIVE: To evaluate the incidence of clinically important traumatic brain injury (ciTBI) in children presenting to a community hospital setting and identified factors associated with computed tomography (CT) use. STUDY DESIGN: Retrospective cohort study of consecutive children presenting with blunt head trauma to a community emergency department or clinic over 12 months. Logistic regression models were used to compare differences in characteristics between patients who received and did not receive CT scans. RESULTS: Of 1007 patients, 62% male, age 14 days-18 years (270 <2 years, 737 ≥2 years), 189 (18%) had CT scans, 2 (0.2%) showed evidence of ciTBI on CT, 13 (1.3%) hospitalized, and none required neurosurgical intervention or died. Factors associated with CT use in patients ≥2 years: history of vomiting (OR 4.08, 95% CI 2.08-7.99, P < .001), change in behavior (OR 2.83, 95% CI 1.63-4.91, P < .001), headache (OR 3.4, 95% CI 1.87-6.16, P < .001), loss of consciousness (OR 2.83, 95% CI 1.38-5.8, P = .004), and abnormal neurologic examination (OR 26.18, 95% CI 2.26-303.05, P = .009). Patients were more likely to receive CT scans in community emergency departments than clinics (OR 7.04, 95% CI 2.40-20.65, P = .002). CONCLUSION: Patients in our community hospital setting are at low risk of ciTBI. The clinical indicators used to determine the need for CT in patients with more significant mechanisms of injury to pediatric or academic centers may not apply to this group. Future studies are required to determine which clinical indications are significant in this setting.

BACKGROUND: Outpatient parenteral antibiotic therapy with peripherally inserted central catheters (PICCs) is safe, clinically effective, and cost effective in pediatric populations cared for at academic and free-standing pediatric hospitals. Our study evaluates the transferability of these findings to a community hospital setting. METHODS: Data were retrospectively collected on PICCs used in children at a community hospital from December 2003 to September 2006. The Fisher exact test and a logistic regression were used for statistical analysis. RESULTS: Thirty-nine PICCs were placed in 34 patients. The total number of catheter days at home was 800 (mean 20.5 +/- 13.9). We demonstrated a 97% success rate in completing therapy at home, with 82.3% completion with a single PICC. Our overall complication rate was 33.3%, consisting of occlusion, accidental displacement, cracks in the catheters, and local irritation. There were no instances of phlebitis or suspected or confirmed catheter infection or sepsis. There were no statistically significant differences in these values compared with reports from major pediatric centers. The cost savings was $1070 per day of home health care when compared with costs of inpatient hospitalization. CONCLUSIONS: We believe that this is the first study to demonstrate the effectiveness of PICC use for outpatient parenteral antibiotic therapy in pediatric patients in a community hospital setting, and demonstrates the ability for this to be done at the standard of care expected at major pediatric centers.

BACKGROUND: The prognosis for children with recurrent/refractory sarcomas is poor. We determined the overall response rate (ORR) and overall survival (OS) of children with recurrent/refractory sarcomas who were given ifosfamide, carboplatin, and etoposide (ICE) in three Children's Cancer Group (CCG) phase I/II trials. PROCEDURE: Children with recurrent/refractory sarcoma were treated with ifosfamide (1,800 mg/m2/day on day 0-4), carboplatin (400 mg/m2/day on day 0-1), etoposide (100 mg/m2/day on day 0-4) and either rhG-CSF (10 microg/kg/day vs. 5 microg/kg/day, CCG-0894, 71 patients), PIXY321 (500-1,000 microg/m2/day, CCG-0924, 14 patients), or rhG-CSF (5 microg/kg/day) and IL-6 (2.5-5 microg/kg/day, CCG-0931, 12 patients). RESULTS: Ninety-seven patients were evaluable for tumor response, 56 male and 41 female, median age 14.1 years (range 2.8-22.5 years). Tumor types were osteosarcoma (OTS) (n = 34), rhabdomyosarcoma (n = 27), Ewing sarcoma (EWS) (n = 21), soft tissue sarcoma-not otherwise specified (n = 5), undifferentiated sarcoma (n = 6), fibrosarcoma (n = 2), peripheral primitive neuroectodermal tumor (n = 1), and extraosseous Ewing (n = 1). The ORR was 51% (27% complete response [CR]). OS at 1 and 2 years was 49% and 28%, respectively. Patients with CR or partial response (PR) had significantly increased 1- and 2-year OS, 71% and 41%, respectively, (P < 0.001). Rhabdomyosarcoma patients with embryonal histology had significant improvement in 1- and 2-year OS: 82% and 46%, respectively, compared with other histologies, (P < 0.005). CONCLUSIONS: The ORR to ICE reinduction chemotherapy in children with recurrent/refractory sarcoma was 51%. OS of 1 and 2 years appeared significantly improved in patients who had CR or PR following ICE reinduction therapy or who had rhabdomyosarcoma with embryonal histology.
