STUDY OBJECTIVE: To determine whether the receipt of more than or equal to 30 mL/kg of intravenous fluid in the first hour after emergency department (ED) arrival is associated with sepsis-attributable mortality among children with hypotensive septic shock.

METHODS: This is a retrospective cohort study set in 57 EDs in the Improving Pediatric Sepsis Outcomes quality improvement collaborative. Patients less than 18 years of age with hypotensive septic shock who received their first intravenous fluid bolus within 1 hour of arrival at the ED were propensity-score matched for probability of receiving more than or equal to 30 mL/kg in the first hour. Sepsis-attributable mortality was compared. We secondarily evaluated the association between the first-hour fluid volume and sepsis-attributable mortality in all children with suspected sepsis in the first hour after arrival at the ED, regardless of blood pressure.

RESULTS: Of the 1,982 subjects who had hypotensive septic shock and received a first fluid bolus within 1 hour of arrival at the ED, 1,204 subjects were propensity matched. In the matched patients receiving more than or equal to 30 mL/kg of fluid, 26 (4.3%) of 602 subjects had 30-day sepsis-attributable mortality compared with 25 (4.2%) of 602 receiving less than 30 mL/kg (odds ratio 1.04, 95% confidence interval 0.59 to 1.83). Among the patients with suspected sepsis regardless of blood pressure, 30-day sepsis-attributable mortality was 3.0% in those receiving more than or equal to 30 mL/kg versus 2.0% in those receiving less than 30 ml/kg (odds ratio 1.52, 95% confidence interval 0.95 to 2.44.) CONCLUSION: In children with hypotensive septic shock receiving a timely first fluid bolus within the first hour of ED care, receiving more than or equal to 30 mL/kg of bolus intravenous fluids in the first hour after arrival at the ED was not associated with mortality compared with receiving less than 30 mL/kg.

Metric Development for the Multicenter Improving Pediatric Sepsis Outcomes (IPSO) Collaborative.

<p><strong>BACKGROUND: </strong>A 56 US hospital collaborative, Improving Pediatric Sepsis Outcomes, has developed variables, metrics and a data analysis plan to track quality improvement (QI)-based patient outcomes over time. Improving Pediatric Sepsis Outcomes expands on previous pediatric sepsis QI efforts by improving electronic data capture and uniformity across sites.</p>

<p><strong>METHODS: </strong>An expert panel developed metrics and corresponding variables to assess improvements across the care delivery spectrum, including the emergency department, acute care units, hematology and oncology, and the ICU. Outcome, process, and balancing measures were represented. Variables and statistical process control charts were mapped to each metric, elucidating progress over time and informing plan-do-study-act cycles. Electronic health record (EHR) abstraction feasibility was prioritized. Time 0 was defined as time of earliest sepsis recognition (determined electronically), or as a clinically derived time 0 (manually abstracted), identifying earliest physiologic onset of sepsis.</p>

<p><strong>RESULTS: </strong>Twenty-four evidence-based metrics reflected timely and appropriate interventions for a uniformly defined sepsis cohort. Metrics mapped to statistical process control charts with 44 final variables; 40 could be abstracted automatically from multiple EHRs. Variables, including high-risk conditions and bedside huddle time, were challenging to abstract (reported in &lt;80% of encounters). Size or type of hospital, method of data abstraction, and previous QI collaboration participation did not influence hospitals' abilities to contribute data. To date, 90% of data have been submitted, representing 200 007 sepsis episodes.</p>

<p><strong>CONCLUSIONS: </strong>A comprehensive data dictionary was developed for the largest pediatric sepsis QI collaborative, optimizing automation and ensuring sustainable reporting. These approaches can be used in other large-scale sepsis QI projects in which researchers seek to leverage EHR data abstraction.</p>

Development of a Quality Improvement Learning Collaborative to Improve Pediatric Sepsis Outcomes.

<p>Pediatric sepsis is a major public health problem. Published treatment guidelines and several initiatives have increased adherence with guideline recommendations and have improved patient outcomes, but the gains are modest, and persistent gaps remain. The Children's Hospital Association Improving Pediatric Sepsis Outcomes (IPSO) collaborative seeks to improve sepsis outcomes in pediatric emergency departments, ICUs, general care units, and hematology/oncology units. We developed a multicenter quality improvement learning collaborative of US children's hospitals. We reviewed treatment guidelines and literature through 2 in-person meetings and multiple conference calls. We defined and analyzed baseline sepsis-attributable mortality and hospital-onset sepsis and developed a key driver diagram (KDD) on the basis of treatment guidelines, available evidence, and expert opinion. Fifty-six hospital-based teams are participating in IPSO; 100% of teams are engaged in educational and information-sharing activities. A baseline, sepsis-attributable mortality of 3.1% was determined, and the incidence of hospital-onset sepsis was 1.3 cases per 1000 hospital admissions. A KDD was developed with the aim of reducing both the sepsis-attributable mortality and the incidence of hospital-onset sepsis in children by 25% from baseline by December 2020. To accomplish these aims, the KDD primary drivers focus on improving the following: treatment of infection; recognition, diagnosis, and treatment of sepsis; de-escalation of unnecessary care; engagement of patients and families; and methods to optimize performance. IPSO aims to improve sepsis outcomes through collaborative learning and reliable implementation of evidence-based interventions.</p>

Evaluating Pediatric Sepsis Definitions Designed for Electronic Health Record Extraction and Multicenter Quality Improvement.

<p><strong>OBJECTIVES: </strong>To describe the Children's Hospital Association's Improving Pediatric Sepsis Outcomes sepsis definitions and the identified patients; evaluate the definition using a published framework for evaluating sepsis definitions.</p>

<p><strong>DESIGN: </strong>Observational cohort.</p>

<p><strong>SETTING: </strong>Multicenter quality improvement collaborative of 46 hospitals from January 2017 to December 2018, excluding neonatal ICUs.</p>

<p><strong>PATIENTS: </strong>Improving Pediatric Sepsis Outcomes Sepsis was defined by electronic health record evidence of suspected infection and sepsis treatment or organ dysfunction. A more severely ill subgroup, Improving Pediatric Sepsis Outcomes Critical Sepsis, was defined, approximating septic shock.</p>

<p><strong>INTERVENTIONS: </strong>Participating hospitals identified patients, extracted data, and transferred de-identified data to a central data warehouse. The definitions were evaluated across domains of reliability, content validity, construct validity, criterion validity, measurement burden, and timeliness.</p>

<p><strong>MEASUREMENTS AND MAIN RESULTS: </strong>Forty hospitals met data quality criteria across four electronic health record platforms. There were 23,976 cases of Improving Pediatric Sepsis Outcomes Sepsis, including 8,565 with Improving Pediatric Sepsis Outcomes Critical Sepsis. The median age was 5.9 years. There were 10,316 (43.0%) immunosuppressed or immunocompromised patients, 4,135 (20.3%) with central lines, and 2,352 (11.6%) chronically ventilated. Among Improving Pediatric Sepsis Outcomes Sepsis patients, 60.8% were admitted to intensive care, 26.4% had new positive-pressure ventilation, and 19.7% received vasopressors. Median hospital length of stay was 6.0 days (3.0-13.0 d). All-cause 30-day in-hospital mortality was 958 (4.0%) in Improving Pediatric Sepsis Outcomes Sepsis; 541 (6.3%) in Improving Pediatric Sepsis Outcomes Critical Sepsis. The Improving Pediatric Sepsis Outcomes Sepsis definitions demonstrated strengths in content validity, convergent construct validity, and criterion validity; weakness in reliability. Improving Pediatric Sepsis Outcomes Sepsis definitions had significant initial measurement burden (median time from case completion to submission: 15 mo [interquartile range, 13-18 mo]); timeliness improved once data capture was established (median, 26 d; interquartile range, 23-56 d).</p>

<p><strong>CONCLUSIONS: </strong>The Improving Pediatric Sepsis Outcomes Sepsis definitions demonstrated feasibility for large-scale data abstraction. The patients identified provide important information about children treated for sepsis. When operationalized, these definitions enabled multicenter identification and data aggregation, indicating practical utility for quality improvement.</p>
