RESUMO

OBJECTIVE: It is unclear which pediatric emergency departments (PEDs) have a point-of-care ultrasound (POCUS) credentialing process or if this process is consistent per expert guidelines. Our objective was to describe formalized POCUS credentialing processes across PEDs that are active in the pediatric emergency medicine POCUS (P2) Network. METHODS: A survey was developed from nationally recommended credentialing guidelines. This anonymous survey was sent out to the P2 Network comprising more than 230 members involved in pediatric POCUS. The survey was analyzed using descriptive analysis with counts and percentages. RESULTS: A total of 36 PEDs responded to the survey. All departments had a faculty member in charge of maintaining the credentialing process, and all faculty members had POCUS education available; 88.6% of education was scheduled didactics or bedside teaching. There were 80.6% of PEDs that had a process for internally credentialing faculty. Some PEDs offered protected education for POCUS, however, 44.8% had <50% of their faculty credentialed. There were 4 PEDs that offered incentives for completion of POCUS credentialing including salary bonuses; only 1 offered shift buy down as incentive. That PED had 100% of its faculty credentialed. All PEDs performed quality assurance on POCUS scans done in the ED, most done weekly. Billing for scans occurred in 26 PEDs. Skin/soft tissue and focused assessment with sonography for trauma were the 2 most common applications credentialed. CONCLUSIONS: Among PEDs surveyed, there was a lack of standardization of POCUS resources and components of credentialing. Incentives may be beneficial in improving credentialing faculty and standardizing the credentialing process.

RESUMO

OBJECTIVES: Viral lower respiratory tract infection (vLRTI) contributes to substantial morbidity and mortality in children. Diagnosis is typically confirmed by reverse transcriptase polymerase chain reaction (RT-PCR) of nasopharyngeal specimens in hospitalized patients; however, it is unknown whether nasopharyngeal detection accurately reflects presence of virus in the lower respiratory tract (LRT). This study evaluates agreement between viral detection from nasopharyngeal specimens by RT-PCR compared with metagenomic next-generation RNA sequencing (RNA-Seq) from tracheal aspirates (TAs). DESIGN: This is an analysis of of a seven-center prospective cohort study. SETTING: Seven PICUs within academic children's hospitals in the United States. PATIENTS: Critically ill children (from 1 mo to 18 yr) who required mechanical ventilation via endotracheal tube for greater than or equal to 72 hours. INTERVENTIONS: We evaluated agreement in viral detection between paired upper and LRT samples. Results of clinical nasopharyngeal RT-PCR were compared with TA RNA-Seq. Positive and negative predictive agreement and Cohen's Kappa were used to assess agreement. MEASUREMENTS AND MAIN RESULTS: Of 295 subjects with paired testing available, 200 (68%) and 210 (71%) had positive viral testing by RT-PCR from nasopharyngeal and RNA-Seq from TA samples, respectively; 184 (62%) were positive by both nasopharyngeal RT-PCR and TA RNA-Seq for a virus, and 69 (23%) were negative by both methods. Nasopharyngeal RT-PCR detected the most abundant virus identified by RNA-Seq in 92.4% of subjects. Among the most frequent viruses detected, respiratory syncytial virus demonstrated the highest degree of concordance (κ = 0.89; 95% CI, 0.83-0.94), whereas rhinovirus/enterovirus demonstrated lower concordance (κ = 0.55; 95% CI, 0.44-0.66). Nasopharyngeal PCR was more likely to detect multiple viruses than TA RNA-Seq (54 [18.3%] vs 24 [8.1%], p ≤ 0.001). CONCLUSIONS: Viral nucleic acid detection in the upper versus LRT reveals good overall agreement, but concordance depends on the virus. Further studies are indicated to determine the utility of LRT sampling or the use of RNA-Seq to determine LRTI etiology.

RESUMO

OBJECTIVE: To determine the association between adjunct corticosteroid therapy and quality of life (QoL) outcomes in children with signs and symptoms of lower respiratory tract infection and clinical suspicion for community-acquired pneumonia (CAP) in the emergency department (ED). METHODS: Secondary analysis from a prospective cohort study of children aged 3 months to 18 years with signs and symptoms of LRTI and a chest radiograph for suspected CAP in the ED, excluding children with recent (within 14 days) systemic corticosteroid use. The primary exposure was receipt of corticosteroids during the ED visit. Outcomes were QoL measures and unplanned visits. Multivariable regression was used to evaluate the association between corticosteroid therapy and outcomes. RESULTS: Of 898 children, 162 (18%) received corticosteroids. Children who received corticosteroids were more frequently boys (62%), Black (45%), had history of asthma (58%), previous pneumonia (16%), presence of wheeze (74%), and more severe illness at presentation (6%). Ninety-six percent were treated for asthma as defined by report of asthma or receipt of ß-agonist in the ED. Receipt of corticosteroids was not associated with QoL measures: days of activity missed (adjusted incident rate ratio [aIRR], 0.84; 95% confidence interval [CI], 0.63-1.11) and days of work missed (aIRR, 0.88; 95% CI, 0.60-1.27). There was a statistically significant interaction between age (>2 years) and corticosteroids receipt; the patients had fewer days of activity missed (aIRR, 0.62; 95% CI, 0.46-0.83), with no effect on children 2 years or younger (aIRR, 0.83; 95% CI, 0.54-1.27). Corticosteroid treatment was not associated with unplanned visit (odds ratio, 1.37; 95% CI, 0.69-2.75). CONCLUSIONS: In this cohort of children with suspected CAP, receipt of corticosteroids was associated with asthma history and was not associated with missed days of activity or work, except in a subset of children aged older than 2 years.

RESUMO

OBJECTIVE: To identify practice patterns in the duration of prescribed antibiotics for the treatment of ambulatory children with community-acquired pneumonia (CAP) and to compare the frequency of adverse clinical outcomes between children prescribed short-vs prolonged-duration antibiotics. STUDY DESIGN: We performed a retrospective cohort study from 2010-2016 using the IBM Watson MarketScan Medicaid Database, a claims database of publicly insured patients from 11 states. We included children 1-18 years old with outpatient CAP who filled a prescription for oral antibiotics (n = 121 846 encounters). We used multivariable logistic regression to determine associations between the duration of prescribed antibiotics (5-9 days vs 10-14 days) and subsequent hospitalizations, new antibiotic prescriptions, and acute care visits. Outcomes were measured during the 14 days following the end of the dispensed antibiotic course. RESULTS: The most commonly prescribed duration of antibiotics was 10 days (82.8% of prescriptions), and 10.5% of patients received short-duration therapy. During the follow-up period, 0.2% of patients were hospitalized, 6.2% filled a new antibiotic prescription, and 5.1% had an acute care visit. Compared with the prolonged-duration group, the aORs for hospitalization, new antibiotic prescriptions, and acute care visits in the short-duration group were 1.16 (95% CI 0.80-1.66), 0.93 (95% CI 0.85-1.01), and 1.06 (95% CI 0.98-1.15), respectively. CONCLUSIONS: Most children treated for CAP as outpatients are prescribed at least 10 days of antibiotic therapy. Among pediatric outpatients with CAP, no significant differences were found in rates of adverse clinical outcomes between patients prescribed short-vs prolonged-duration antibiotics.

RESUMO

OBJECTIVES: To describe antibiotic prescribing patterns in ambulatory children with community-acquired pneumonia and to assess the relationship between antibiotic selection and clinical outcomes. STUDY DESIGN: This was a retrospective cohort study of ambulatory Medicaid-enrolled children 0-18 years of age diagnosed with community-acquired pneumonia from 2010 to 2016. The exposure was antibiotic class: narrow-spectrum (aminopenicillins), broad-spectrum (amoxicillin/clavulanate and cephalosporins), macrolide monotherapy, macrolides with narrow-spectrum antibiotics, or macrolides with broad-spectrum antibiotics. The associations between antibiotic selection and the outcomes of subsequent hospitalization and development of severe pneumonia (chest drainage procedure, intensive care admission, mechanical ventilation) were assessed, controlling for measures of illness severity. RESULTS: Among 252 177 outpatient pneumonia visits, macrolide monotherapy was used in 43.2%, narrow-spectrum antibiotics in 26.1%, and broad-spectrum antibiotics in 24.7%. A total of 1488 children (0.59%) were subsequently hospitalized and 117 (0.05%) developed severe pneumonia. Compared with children receiving narrow-spectrum antibiotics, the odds of subsequent hospitalization were higher in children receiving broad-spectrum antibiotics (aOR, 1.34; 95% CI, 1.17-1.52) and lower in children receiving macrolide monotherapy (aOR, 0.64; 95% CI, 0.55-0.73) and macrolides with narrow-spectrum antibiotics (aOR, 0.62; 95% CI, 0.39-0.97). Children receiving macrolide monotherapy had lower odds of developing severe pneumonia than children receiving narrow-spectrum antibiotics (aOR, 0.56; 95% CI, 0.33-0.93). However, the absolute risk difference was <0.5% for all analyses. CONCLUSIONS: Macrolides are the most commonly prescribed antibiotic for ambulatory children with community-acquired pneumonia. Subsequent hospitalization and severe pneumonia are rare. Future efforts should focus on reducing broad-spectrum and macrolide antibiotic prescribing.

RESUMO

OBJECTIVES: To evaluate whether the implementation of a multiplex gastrointestinal pathogen panel (GIP) was associated with changes in Clostridioides difficile (C difficile) testing and detection rates. STUDY DESIGN: We conducted an observational study using interrupted time series analysis and included pediatric patients with testing capable of detecting C difficile. From 2013 to 2015 ("conventional diagnostic era"), stool testing included C difficile-selective polymerase chain reaction and other pathogen-specific tests. From 2015 to 2017 ("GIP era"), C difficile polymerase chain reaction was available along with the GIP, which detected 22 pathogens including C difficile, and replaced the need for additional tests. Outcomes included C difficile testing and detection rates in ambulatory, emergency department, and inpatient settings. RESULTS: There were 6841 tests performed and 1214 C difficile positive results. Across the 3 settings, GIP era had significantly higher C difficile testing (1.7-2.3 times higher) and C difficile detection rates (1.9-3.4 times higher) compared with conventional diagnostic era. After adjusting for the number of tests performed, detection rates were no longer significantly different. Of C difficile positive GIPs, 31% were coinfected with another organism. With GIP testing, patients 1 year of age had a significantly higher C difficile percent positivity than 2-year-old (P = .02) and 3- to 18-year-old children (P < .01). Younger children with C difficile were more likely to be coinfected (P < .01). CONCLUSIONS: Introducing a multiplex panel led to increased C difficile testing, which resulted in increased C difficile detection rates and potential identification and treatment of colonized patients. This highlights an important target for diagnostic stewardship and the challenges associated with multiplex testing.

RESUMO

OBJECTIVE: To assess hospital-level variability in diagnostic testing and outcomes for children with neurologic impairment hospitalized with pneumonia. STUDY DESIGN: A retrospective cohort study of 27 455 children ages 1-18 years with neurologic impairment hospitalized with pneumonia at 39 children's hospitals. K-means clustering was used to assign each hospital to 1 of 3 groups (termed A, B, and C) based on similar diagnostic testing patterns. Outcomes of hospital-level median length of stay (LOS), 30-day readmissions, and pneumonia-associated complications were compared while controlling for patient differences. RESULTS: Overall, 48.5% had comorbid complex chronic conditions, and 25.4% were assisted with medical technology. Outcomes and diagnostic testing varied across hospitals: median hospital-level LOS, 3.2 days (IQR 2.8-3.8); median readmission, 8.4% (IQR 6.8,-10.0); and median pneumonia-associated complication rate, 23.1% (IQR 18.7-26.8). Despite similar populations, hospitals in group A tended to perform fewer tests than those in groups B and C. Across hospital groups, there was a significant difference in adjusted readmission rates (group A 7.2%, group B 9.0%, group C 7.7%, P = .003). There was no significant difference in adjusted median LOS (group A 3.4 days, group B 3.2 days, group C 3.3 days, P = .3) or adjusted pneumonia-associated complication rates (group A 22.5%, group B 22.5%, group C 25.0%, P = .6). CONCLUSIONS: For children with neurologic impairment hospitalized with pneumonia, across hospital differences in diagnostic testing were not associated with clinically meaningful differences in outcomes. High-utilizing hospitals may be able to decrease diagnostic testing for children with neurologic impairment hospitalized with pneumonia without adversely impacting outcomes.

RESUMO

OBJECTIVE: To determine the interrater reliability (IRR) of lung ultrasonography (LUS) and chest radiography (CXR) and evaluate the accuracy of LUS compared with CXR for detecting pediatric pneumonia compared with chest computed tomography (CT) scan. STUDY DESIGN: This was a prospective cohort study of children aged 3 months to 18 years with a CXR and LUS performed between May 1, 2012, and January 31, 2014 with or without a clinical diagnosis of pneumonia. Four pediatric radiologists blinded to clinical information reported findings for the CXR and LUS images. IRR was estimated for 50 LUS and CXR images. The main outcome was the finding from CT ordered clinically or the probability of the CT finding for patients clinically requiring CT. Two radiologists reviewed CT scans to determine an overall finding. Latent class analysis was used to evaluate the sensitivity and specificity for findings (eg, consolidation) for LUS and CXR compared with CT. RESULTS: Of the 132 patients in the cohort, 36 (27%) had CT performed for a clinical reason. Pneumonia was clinically documented in 47 patients (36%). The IRR for lung consolidation was 0.55 (95% CI, 0.40-0.70) for LUS and 0.36 (95% CI, 0.21-0.51) for CXR. The sensitivity for detecting consolidation, interstitial disease, and pleural effusion was statistically similar for LUS and CXR compared with CT; however, specificity was higher for CXR. The negative predictive value was similar for CXR and LUS. CONCLUSIONS: LUS has a sufficiently high IRR for detection of consolidation. Compared with CT, LUS and CXR have similar sensitivity, but CXR is more specific for findings indicating pneumonia.
