Abstract

OBJECTIVES:  Clinical decision support (CDS) has promise for the implementation of antimicrobial stewardship programs (ASPs) in the emergency department (ED). We sought to assess the usability of a newly developed automated CDS to improve guideline-adherent antibiotic prescribing for pediatric community-acquired pneumonia (CAP) and urinary tract infection (UTI).

METHODS:  We conducted comparative usability testing between an automated, prototype CDS-enhanced discharge order set and standard order set, for pediatric CAP and UTI antibiotic prescribing. After an extensive user-centered design process, the prototype CDS was integrated into the electronic health record, used passive activation, and embedded locally adapted prescribing guidelines. Participants were randomized to interact with three simulated ED scenarios of children with CAP or UTI, across both systems. Measures included task completion, decision-making and usability errors, clinical actions (order set use and correct antibiotic selection), as well as objective measures of system usability, utility, and workload using the National Aeronautics and Space Administration Task Load Index (NASA-TLX). The prototype CDS was iteratively refined to optimize usability and workflow.

RESULTS:  Usability testing in 21 ED clinical providers demonstrated that, compared to the standard order sets, providers preferred the prototype CDS, with improvements in domains such as explanations of suggested antibiotic choices ( < 0.001) and provision of additional resources on antibiotic prescription ( < 0.001). Simulated use of the CDS also led to overall improved guideline-adherent prescribing, with a 31% improvement for CAP. A trend was present toward absolute workload reduction. Using the NASA-TLX, workload scores for the current system were median 26, interquartile ranges (IQR): 11 to 41 versus median 25, and IQR: 10.5 to 39.5 for the CDS system ( = 0.117).

CONCLUSION:  Our CDS-enhanced discharge order set for ED antibiotic prescribing was strongly preferred by users, improved the accuracy of antibiotic prescribing, and trended toward reduced provider workload. The CDS was optimized for impact on guideline-adherent antibiotic prescribing from the ED and end-user acceptability to support future evaluative trials of ED ASPs.

Abstract

Importance: Pediatric sepsis definitions have evolved, and some have proposed using the measure used in adults to quantify organ dysfunction, a Sequential Organ Failure Assessment (SOFA) score of 2 or more in the setting of suspected infection. A pediatric adaptation of SOFA (pSOFA) showed excellent discrimination for mortality in critically ill children but has not been evaluated in an emergency department (ED) population.

Objective: To delineate test characteristics of the pSOFA score for predicting in-hospital mortality among (1) all patients and (2) patients with suspected infection treated in pediatric EDs.

Design, Setting, and Participants: This retrospective cohort study took place from January 1, 2012, to January 31, 2020 in 9 US children's hospitals included in the Pediatric Emergency Care Applied Research Network (PECARN) Registry. The data was analyzed from February 1, 2020, to April 18, 2022. All ED visits for patients younger than 18 years were included.

Exposures: ED pSOFA score was assigned by summing maximum pSOFA organ dysfunction components during ED stay (each 0-4 points). In the subset with suspected infection, visit meeting criteria for sepsis (suspected infection with a pSOFA score of 2 or more) and septic shock (suspected infection with vasoactive infusion and serum lactate level >18.0 mg/dL) were identified.

Main Outcomes and Measures: Test characteristics of pSOFA scores of 2 or more during the ED stay for hospital mortality.

Results: A total of 3 999 528 (female, 47.3%) ED visits were included. pSOFA scores ranged from 0 to 16, with 126 250 visits (3.2%) having a pSOFA score of 2 or more. pSOFA scores of 2 or more had sensitivity of 0.65 (95% CI, 0.62-0.67) and specificity of 0.97 (95% CI, 0.97-0.97), with negative predictive value of 1.0 (95% CI, 1.00-1.00) in predicting hospital mortality. Of 642 868 patients with suspected infection (16.1%), 42 992 (6.7%) met criteria for sepsis, and 374 (0.1%) met criteria for septic shock. Hospital mortality rates for suspected infection (599 502), sepsis (42 992), and septic shock (374) were 0.0%, 0.9%, and 8.0%, respectively. The pSOFA score had similar discrimination for hospital mortality in all ED visits (area under receiver operating characteristic curve, 0.81; 95% CI, 0.79-0.82) and the subset with suspected infection (area under receiver operating characteristic curve, 0.82; 95% CI, 0.80-0.84).

Conclusions and Relevance: In a large, multicenter study of pediatric ED visits, a pSOFA score of 2 or more was uncommon and associated with increased hospital mortality yet had poor sensitivity as a screening tool for hospital mortality. Conversely, children with a pSOFA score of 2 or less were at very low risk of death, with high specificity and negative predictive value. Among patients with suspected infection, patients with pSOFA-defined septic shock demonstrated the highest mortality.

Abstract

<p><strong>OBJECTIVES: </strong>Wait time for emergency care is a quality measure that affects clinical outcomes and patient satisfaction. It is unknown if there is racial/ethnic variability in this quality measure in pediatric emergency departments (PEDs). We aim to determine whether racial/ethnic differences exist in wait times for children presenting to PEDs and examine between-site and within-site differences.</p>

<p><strong>METHODS: </strong>We conducted a retrospective cohort study for PED encounters in 2016 using the Pediatric Emergency Care Applied Research Network Registry, an aggregated deidentified electronic health registry comprising 7 PEDs. Patient encounters were included among all patients 18 years or younger at the time of the ED visit. We evaluated differences in emergency department wait time (time from arrival to first medical evaluation) considering patient race/ethnicity as the exposure.</p>

<p><strong>RESULTS: </strong>Of 448,563 visits, median wait time was 35 minutes (interquartile range, 17-71 minutes). Compared with non-Hispanic White (NHW) children, non-Hispanic Black (NHB), Hispanic, and other race children waited 27%, 33%, and 12% longer, respectively. These differences were attenuated after adjusting for triage acuity level, mode of arrival, sex, age, insurance, time of day, and month [adjusted median wait time ratios (95% confidence intervals): 1.11 (1.10-1.12) for NHB, 1.12 (1.11-1.13) for Hispanic, and 1.05 (1.03-1.06) for other race children compared with NHW children]. Differences in wait time for NHB and other race children were no longer significant after adjusting for clinical site. Fully adjusted median wait times among Hispanic children were longer compared with NHW children [1.04 (1.03-1.05)].</p>

<p><strong>CONCLUSIONS: </strong>In unadjusted analyses, non-White children experienced longer PED wait times than NHW children. After adjusting for illness severity, patient demographics, and overcrowding measures, wait times for NHB and other race children were largely determined by site of care. Hispanic children experienced longer within-site and between-site wait times compared with NHW children. Additional research is needed to understand structures and processes of care contributing to wait time differences between sites that disproportionately impact non-White patients.</p>

Abstract

<p><strong>BACKGROUND: </strong>Appendicitis is the most common surgical condition in pediatric emergency department (ED) patients. Prompt diagnosis can reduce morbidity, including appendiceal perforation. The goal of this study was to measure racial/ethnic differences in rates of: 1) appendiceal perforation; 2) delayed diagnosis of appendicitis; 3) diagnostic imaging during prior visit(s).</p>

<p><strong>METHODS: </strong>3-year multicenter (7 EDs) retrospective cohort study of children diagnosed with appendicitis using the Pediatric Emergency Care Applied Research Network Registry. Delayed diagnosis was defined as having at least one prior ED visit within 7 days preceding appendicitis diagnosis. We performed multivariable logistic regression to measure associations of race/ethnicity (non-Hispanic [NH]-white, NH-Black, Hispanic, Other) with: 1) appendiceal perforation; 2) delayed diagnosis of appendicitis; 3) diagnostic imaging during prior visit(s).</p>

<p><strong>RESULTS: </strong>Of 7298 patients with appendicitis and documented race/ethnicity, 2567 (35.2%) had appendiceal perforation. In comparison to NH-whites, NH-Black children had higher likelihood of perforation (36.5% vs. 34.9%; aOR 1.21 [95% CI 1.01, 1.45]). 206 (2.8%) had a delayed diagnosis of appendicitis. NH-Black children were more likely to have delayed diagnoses (4.7% vs. 2.0%; aOR 1.81 [1.09, 2.98]. Eighty-nine (43.2%) patients with delayed diagnosis had abdominal imaging during their prior visits. In comparison to NH-whites, NH-Black children were less likely to undergo any imaging (28.2% vs. 46.2%; aOR 0.41 [0.18, 0.96]), or definitive imaging (e.g. US/CT/MRI) (10.3% vs. 35.9%; aOR 0.15 [0.05, 0.50]) during prior visits.</p>

<p><strong>CONCLUSIONS: </strong>In this multicenter cohort, there were racial disparities in appendiceal perforation. There were also racial disparities in rates of delayed diagnosis of appendicitis and diagnostic imaging during prior ED visits. These disparities in diagnostic imaging may lead to delays in appendicitis diagnosis, and thus, may contribute to higher perforation rates demonstrated among minority children.</p>

Abstract

<p><strong>OBJECTIVES: </strong>To test the hypotheses that minority children with long-bone fractures are less likely to (1) receive analgesics, (2) receive opioid analgesics, and (3) achieve pain reduction.</p>

<p><strong>METHODS: </strong>We performed a 3-year retrospective cross-sectional study of children &lt;18 years old with long-bone fractures using the Pediatric Emergency Care Applied Research Network Registry (7 emergency departments). We performed bivariable and multivariable logistic regression to measure the association between patient race and ethnicity and (1) any analgesic, (2) opioid analgesic, (3) ≥2-point pain score reduction, and (4) optimal pain reduction (ie, to mild or no pain).</p>

<p><strong>RESULTS: </strong>In 21 069 visits with moderate-to-severe pain, 86.1% received an analgesic and 45.4% received opioids. Of 8533 patients with reassessment of pain, 89.2% experienced ≥2-point reduction in pain score and 62.2% experienced optimal pain reduction. In multivariable analyses, minority children, compared with non-Hispanic (NH) white children, were more likely to receive any analgesics (NH African American: adjusted odds ratio [aOR] 1.72 [95% confidence interval 1.51-1.95]; Hispanic: 1.32 [1.16-1.51]) and achieve ≥2-point reduction in pain (NH African American: 1.42 [1.14-1.76]; Hispanic: 1.38 [1.04-1.83]) but were less likely to receive opioids (NH African American: aOR 0.86 [0.77-0.95]; Hispanic: aOR 0.86 [0.76-0.96]) or achieve optimal pain reduction (NH African American: aOR 0.78 [0.67-0.90]; Hispanic: aOR 0.80 [0.67-0.95]).</p>

<p><strong>CONCLUSIONS: </strong>There are differences in process and outcome measures by race and ethnicity in the emergency department management of pain among children with long-bone fractures. Although minority children are more likely to receive analgesics and achieve ≥2-point reduction in pain, they are less likely to receive opioids and achieve optimal pain reduction.</p>

Abstract

<p><strong>OBJECTIVE: </strong>To examine the use, efficacy, and safety of intravenous magnesium sulfate (IVMg) in children with asthma whose emergency department (ED) management is recorded in the Pediatric Emergency Care Applied Research Network (PECARN) Registry.</p>

<p><strong>STUDY DESIGN: </strong>This multicenter retrospective cohort study analyzed clinical data from 7 EDs from 2012 to 2017. We described use of IVMg in children aged 2-17&nbsp;years treated for acute asthma and its effect on blood pressure. We also used multivariable analysis to examine factors associated with use of IVMg and its association with return visits within 72&nbsp;hours.</p>

<p><strong>RESULTS: </strong>Across 61 854 asthma visits for children, clinicians administered IVMg in 6497 (10.5%). Median time from triage to IVMg administration was 154&nbsp;minutes (IQR 84, 244). During 22 495 ED visits resulting in hospitalization after ED treatment, IVMg was administered in 5774 (25.7%) (range by site 15.9%, 50.6%). Patients were discharged home from the ED after 11.1% of IVMg administrations, and hypotension occurred after 6.8%. Variation in IVMg use was not explained by patient characteristics. Revisits did not differ between patients discharged after IVMg and those not receiving IVMg.</p>

<p><strong>CONCLUSIONS: </strong>In PECARN Registry EDs, administration of IVMg occurs late in ED treatment, for a minority of the children likely to benefit, with variation between sites, which suggests the current clinical role for IVMg in preventing hospitalization is limited. Discharge after IVMg administration is likely safe. Further research should prospectively assess the efficacy and safety of early IVMg administration.</p>

Abstract

<p><strong>OBJECTIVE: </strong>To measure the variability in discharge opioid prescription practices for children discharged from the emergency department (ED) with a long-bone fracture.</p>

<p><strong>DESIGN: </strong>A retrospective cohort study of pediatric ED visits in 2015.</p>

<p><strong>SETTING: </strong>Four pediatric EDs.</p>

<p><strong>SUBJECTS: </strong>Children aged four to 18 years with a long-bone fracture discharged from the ED.</p>

<p><strong>METHODS: </strong>A multisite registry of electronic health record data (PECARN Registry) was analyzed to determine the proportion of children receiving an opioid prescription on ED discharge. Multivariable logistic regression was performed to determine characteristics associated with receipt of an opioid prescription.</p>

<p><strong>RESULTS: </strong>There were 5,916 visits with long-bone fractures; 79% involved the upper extremity, and 27% required reduction. Overall, 15% of children were prescribed an opioid at discharge, with variation between the four EDs: A = 8.2% (95% confidence interval [CI] = 6.9-9.7%), B = 12.1% (95% CI = 10.5-14.0%), C = 16.9% (95% CI = 15.2-18.8%), D = 23.8% (95% CI = 21.7-26.1%). Oxycodone was the most frequently prescribed opioid. In the regression analysis, in addition to variation by ED site of care, age 12-18 years, white non-Hispanic, private insurance status, reduced fracture, and severe pain documented during the ED visit were associated with increased opioid prescribing.</p>

<p><strong>CONCLUSIONS: </strong>For children with a long-bone fracture, discharge opioid prescription varied widely by ED site of care. In addition, black patients, Hispanic patients, and patients with government insurance were less likely to be prescribed opioids. This variability in opioid prescribing was not accounted for by patient- or injury-related factors that are associated with increased pain. Therefore, opioid prescribing may be modifiable, but evidence to support improved outcomes with specific treatment regimens is lacking.</p>

Abstract

<p><strong>STUDY OBJECTIVE: </strong>To determine the effect of providing risk estimates of clinically important traumatic brain injuries and management recommendations on emergency department (ED) outcomes for children with isolated intermediate Pediatric Emergency Care Applied Research Network clinically important traumatic brain injury risk factors.</p>

<p><strong>METHODS: </strong>This was a secondary analysis of a nonrandomized clinical trial with concurrent controls, conducted at 5 pediatric and 8 general EDs between November 2011 and June 2014, enrolling patients younger than 18 years who had minor blunt head trauma. After a baseline period, intervention sites received electronic clinical decision support providing patient-level clinically important traumatic brain injury risk estimates and management recommendations. The following primary outcomes in patients with one intermediate Pediatric Emergency Care Applied Research Network risk factor were compared before and after clinical decision support: proportion of ED computed tomography (CT) scans, adjusted for age, time trend, and site; and prevalence of clinically important traumatic brain injuries.</p>

<p><strong>RESULTS: </strong>The risk of clinically important traumatic brain injuries was known for 3,859 children with isolated findings (1,711 at intervention sites before clinical decision support, 1,702 at intervention sites after clinical decision support, and 446 at control sites). In this group, pooled CT proportion decreased from 24.2% to 21.6% after clinical decision support (odds ratio 0.86; 95% confidence interval 0.73 to 1.01). Decreases in CT use were noted across intervention EDs, but not in controls. The pooled adjusted odds ratio for CT use after clinical decision support was 0.73 (95% confidence interval 0.60 to 0.88). Among the entire cohort, clinically important traumatic brain injury was diagnosed at the index ED visit for 37 of 37 (100%) patients before clinical decision support and 32 of 33 patients (97.0%) after clinical decision support.</p>

<p><strong>CONCLUSION: </strong>Providing specific risks of clinically important traumatic brain injury through electronic clinical decision support was associated with a modest and safe decrease in ED CT use for children at nonnegligible risk of clinically important traumatic brain injuries.</p>

Abstract

<p><strong>BACKGROUND: </strong> Electronic health record (EHR)-based registries allow for robust data to be derived directly from the patient clinical record and can provide important information about processes of care delivery and patient health outcomes.</p>

<p><strong>METHODS: </strong> A data dictionary, and subsequent data model, were developed describing EHR data sources to include all processes of care within the emergency department (ED). ED visit data were deidentified and XML files were created and submitted to a central data coordinating center for inclusion in the registry. Automated data quality control occurred prior to submission through an application created for this project. Data quality reports were created for manual data quality review.</p>

<p><strong>RESULTS: </strong> The Pediatric Emergency Care Applied Research Network (PECARN) Registry, representing four hospital systems and seven EDs, demonstrates that ED data from disparate health systems and EHR vendors can be harmonized for use in a single registry with a common data model. The current PECARN Registry represents data from 2,019,461 pediatric ED visits, 894,503 distinct patients, more than 12.5 million narrative reports, and 12,469,754 laboratory tests and continues to accrue data monthly.</p>

<p><strong>CONCLUSION: </strong> The Registry is a robust harmonized clinical registry that includes data from diverse patients, sites, and EHR vendors derived via data extraction, deidentification, and secure submission to a central data coordinating center. The data provided may be used for benchmarking, clinical quality improvement, and comparative effectiveness research.</p>
