Quality improvement in pediatric sepsis

Emergency Department Sepsis Triage Scoring Tool Elements Associated With Hypotension Within 24 Hours in Children With Fever and Tachycardia

OBJECTIVE

Pediatric sepsis screening is becoming the standard of care for children presenting to the emergency department (ED) and has been shown to improve recognition of severe sepsis, but it is unknown if these screening tools can predict progression of disease. The objective of this study was to determine if any elements of a sepsis triage trigger tool were predictive of progression to hypotensive shock in children presenting to the ED with fever and tachycardia.

METHODS

This study is a retrospective case-control study of children ≤18 years presenting to an ED with fever and tachycardia, comparing those who went on to develop hypotensive shock in the subsequent 24 hours (case) to those who did not (control). Primary outcome was the proportion of encounters where the patient had specific abnormal vital signs or clinical signs as components of the sepsis triage score. The secondary outcomes were the proportion of encounters where the patient had a sepsis risk factor.

RESULTS

During the study period, there were 94 patients who met case criteria and 186 controls selected. In the adjusted multivariable model, the 2 components of the sepsis triage score that were more common in case patients were the presence of severe cerebral palsy (adjusted odds ratio, 9.4 [3.7, 23.9]) and abnormal capillary refill at triage (adjusted odds ratio, 3.1 [1.4, 6.9]).

CONCLUSIONS

Among children who present to a pediatric ED with fever and tachycardia, those with prolonged capillary refill at triage or severe cerebral palsy were more likely to progress to decompensated septic shock, despite routine ED care.

Quality improvement programmes in paediatric sepsis from a global perspective

Sepsis is a major contributor to poor child health outcomes around the world. The high morbidity, mortality, and societal cost associated with paediatric sepsis render it a global health priority, as summarised in Paper 1 of this Series. Sepsis is characterised by a dysregulated host response to infection that manifests as organ failure, and children are uniquely susceptible to sepsis, as discussed in Paper 2. The focus of this third Series paper is quality improvement in paediatric sepsis. The 2017 WHO resolution on sepsis outlined key aims to reduce the burden of sepsis. As of 2024, only a small number of countries have implemented systematic, paediatric-focused quality improvement programmes to raise sepsis awareness, enhance recognition of sepsis, promote timely treatment, and provide long-term support for paediatric sepsis survivors. We examine programme successes and systematic barriers to quality improvement targeting paediatric sepsis. We highlight the need for programme design to consider the entire patient journey, starting with prevention, caregiver awareness, recognition at home, education of the health-care workforce, development of health-care systems, and establishment of long-term family and survivor support extending beyond the intensive care unit. Building on lessons learnt from existing quality improvement programmes, we outline implementation strategies and measures to enable benchmarking. Ultimately, quality improvement on a global scale can only be accelerated through a global learning platform focusing on paediatric sepsis.

Validation of a paediatric sepsis screening tool to identify children with sepsis in the emergency department: a statewide prospective cohort study in Queensland, Australia

OBJECTIVE

The Surviving Sepsis Campaign guidelines recommend the implementation of systematic screening for sepsis. We aimed to validate a paediatric sepsis screening tool and derive a simplified screening tool.

DESIGN

Prospective multicentre study conducted between August 2018 and December 2019. We assessed the performance of the paediatric sepsis screening tool using stepwise multiple logistic regression analyses with 10-fold cross-validation and evaluated the final model at defined risk thresholds.

SETTING

Twelve emergency departments (EDs) in Queensland, Australia.

PARTICIPANTS

3473 children screened for sepsis, of which 523 (15.1%) were diagnosed with sepsis.

INTERVENTIONS

A 32-item paediatric sepsis screening tool including rapidly available information from triage, risk factors and targeted physical examination.

PRIMARY OUTCOME MEASURE

Senior medical officer-diagnosed sepsis combined with the administration of intravenous antibiotics in the ED.

RESULTS

The 32-item paediatric sepsis screening tool had good predictive performance (area under the receiver operating characteristic curve (AUC) 0.80, 95% CI 0.78 to 0.82). A simplified tool containing 16 of 32 criteria had comparable performance and retained an AUC of 0.80 (95% CI 0.78 to 0.82). To reach a sensitivity of 90% (95% CI 87% to 92%), the final model achieved a specificity of 51% (95% CI 49% to 53%). Sensitivity analyses using the outcomes of sepsis-associated organ dysfunction (AUC 0.84, 95% CI 0.81 to 0.87) and septic shock (AUC 0.84, 95% CI 0.81 to 0.88) confirmed the main results.

CONCLUSIONS

A simplified paediatric sepsis screening tool performed well to identify children with sepsis in the ED. Implementation of sepsis screening tools may improve the timely recognition and treatment of sepsis.

Epidemiology and treatment of sepsis at a public pediatric emergency department

Objective

To describe the clinical characteristics and treatment of children with sepsis, severe sepsis, and septic shock at a pediatric emergency department of a public hospital.

Methods

A retrospective, observational study. The medical records of patients included in the hospital Pediatric Sepsis Protocol and patients with discharge ICD-10 A41.9 (sepsis, unspecified), R57 (shock) and A39 (meningococcal meningitis) were evaluated.

Results

A total of 399 patients were included. The prevalence of sepsis, severe sepsis, and septic shock at the emergency room were 0.41%, 0.14% and 0.014%, respectively. The median age was 21.5 months for sepsis, 12 months for severe sepsis, and 20.5 months for septic shock. Sepsis, severe sepsis, and septic shock were more often associated with respiratory diseases. The Respiratory Syncytial Virus was the most common agent. The median time to antibiotic and fluid administration was 3 hours in patients with sepsis and severe sepsis. In patients with septic shock, the median times to administer antibiotics, fluid and vasoactive drugs were 2 hours, 2.5 hours and 6 hours, respectively. The median length of hospital stay for patients with sepsis, severe sepsis and septic shock were 3 days, 4 days and 1 day, respectively. The overall mortality was 2%.

Conclusion

Sepsis had a low prevalence. Early diagnosis and recognition are a challenge for the emergency care pediatrician, the first place of admission.

Pediatric sepsis survival in pediatric and general emergency departments

OBJECTIVE

Understanding differences in mortality rate secondary to sepsis between pediatric and general emergency departments (EDs) would help identify strategies to improve pediatric sepsis care. We aimed to determine if pediatric sepsis mortality differs between pediatric and general EDs.

METHODS

We performed a nationally representative, retrospective cohort study using the 2008-2017 Nationwide Emergency Department Sample (NEDS) to examine visits by patients less than 19 years old with a diagnostic code of severe sepsis or septic shock. We generated national estimates of study outcomes using NEDS survey weights. We compared pediatric to general EDs on the outcomes of ED mortality and hospital mortality. We determined adjusted mortality risk using logistic regression, controlling for age, gender, complex care code, and geographic region.

RESULTS

There were 54,129 weighted pediatric ED visits during the study period with a diagnosis code of severe sepsis or septic shock. Of these visits, 285 died in the ED (0.58%) and 5065 died during their hospital stay (9.8%). Mortality risk prior to ED disposition in pediatric and general EDs was 0.31% and 0.72%, respectively (adjusted odds ratio (aOR), 95% confidence interval (CI): 0.36 (0.14-0.93)). Mortality risk prior to hospital discharge in pediatric and general EDs was 7.5% and 10.9%, respectively (aOR, 95% CI: 0.55 (0.41-0.72)).

CONCLUSIONS

In a nationally representative sample, pediatric mortality from severe sepsis or septic shock was lower in pediatric EDs than in general EDs. Identifying features of pediatric ED care associated with improved sepsis mortality could translate into improved survival for children wherever they present with sepsis.

Multidisciplinary Kaizen Event to Improve Adherence to a Sepsis Clinical Care Guideline

Supplemental Digital Content is available in the text.

Introduction:

Since 2015, the Ann and Robert H. Lurie Children’s Hospital Emergency Department (ED) has improved the recognition and treatment of pediatric sepsis and septic shock. Despite existing clinical care guidelines, the ED had not yet achieved the Surviving Sepsis Campaign timeliness goals for fluid and antibiotic administration.

Methods:

The team conducted a multidisciplinary Kaizen event to evaluate clinical workflows and identify opportunities to improve sepsis care adherence. Using rigorous quality improvement methodology, frontline providers mapped workflows to identify barriers and prioritize emerging solutions.

Results:

Thirty-seven staff members across 17 disciplines participated. Nurses and physicians identified communication gaps at pathway initiation. Access to supplies, inadequate task delegation, and a lack of urgency for a subset of pathway patients delayed treatment. Prioritized interventions included scripted communication tools, a delineated response plan, and standardized reassessment processes. Revisions to the key driver diagram were made after the improvement event, guiding future plan-do-study-act cycles.

Conclusions:

Frontline provider participation in the Kaizen event uncovered barriers to care and identified the root causes of ineffective communication and system process inefficiencies. Engaging key stakeholders from multiple care areas in a candid context was a novel approach to process improvement within our department. The Kaizen methodology is fundamental to developing sustainable quality improvement practices, creating momentum for a continuous improvement culture to engrain quality improvement in practice. The success of Kaizen will shape the format of future ED improvement projects.

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.

Febrile children in the Emergency Department: Frequency and predictors of poor outcome

AIM

To evaluate the frequency and predictors of poor outcome in febrile children presenting to the Emergency Department.

METHODS

Retrospective observational study from the Emergency Department of The Royal Children's Hospital, Melbourne, Australia. All children with presenting complaint of fever or triage temperature >38°C over a 6-month period were included. Poor outcome was defined as: new organ dysfunction or the requirement for organ support therapy (inotrope infusion, mechanical ventilation, renal replacement therapy and extra-corporeal life support). Predictors evaluated were as follows: initial vital signs, blood tests and clinical scores. Odds ratio, sensitivity, specificity and area under the receiver-operating characteristics curve were calculated for each predictor variable.

RESULTS

Between Jan-June 2019, 6217 children met inclusion criteria. Twenty-seven (0.4%) developed new organ dysfunction, 10 (0.2%) required organ support therapy (inotrope infusion in 5, mechanical ventilation in 6, renal replacement therapy in 1, extra-corporeal life support in 1). Odds of new organ dysfunction, requirement for inotropic support and mechanical ventilation were higher with abnormal initial vital signs, blood tests and clinical scores, though overall test characteristics were poor due to infrequency.

CONCLUSION

Poor outcomes were uncommon among febrile children presenting to the Emergency Department. Vital signs, blood tests and clinical scores were poor predictors.

A Pediatric Sepsis Protocol Reduced Mortality and Dysfunctions in a Brazilian Public Hospital

Introduction: Few studies in the literature discuss the benefits of compliance with sepsis bundles in hospitals in low- and middle-income countries, where resources are limited and mortality is high. Methods: This is a retrospective cohort study conducted at a public hospital in a low-income region in Brazil. We evaluated whether completion of a sepsis bundle is associated with reduced in-hospital mortality for sepsis, severe sepsis, and septic shock, as well as prevention of septic shock and organ dysfunction. Bundle compliance required the completion of three items: (1) obtaining blood count and culture, arterial or venous blood gases, and arterial or venous lactate levels; (2) antibiotic infusion within the first hour of diagnosis; and (3) infusion of 10-20 ml/kg saline solution within the first hour of diagnosis. Results: A total of 548 children with sepsis, severe sepsis, or septic shock who were treated at the emergency room from February 2008 to August of 2016 were included in the study. Of those, 371 patients were included in the protocol group and had a lower median length of stay (3 days vs. 11 days; p < 0.001), fewer organ dysfunctions during hospitalization (0 vs. 2, p < 0.001), and a lower probability of developing septic shock. According to a propensity score analysis, mortality was lower during the post-implementation period [2.75 vs. 15.4% (RR 95%IC 0.13 (0.06, 0.27); p < 0.001)]. Conclusions: A simple and low-cost protocol was feasible and yielded good results at a general hospital in a low-income region in Brazil. Protocol use resulted in decreased mortality and progression of dysfunctions and was associated with a reduced probability of developing septic shock.

Identification of Potential Diagnostic Gene Targets for Pediatric Sepsis Based on Bioinformatics and Machine Learning

Purpose: To develop a comprehensive differential expression gene profile as well as a prediction model based on the expression analysis of pediatric sepsis specimens. Methods: In this study, compared with control specimens, a total of 708 differentially expressed genes in pediatric sepsis (case-control at a ratio of 1:3) were identified, including 507 up-regulated and 201 down-regulated ones. The Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis of differentially expressed genes indicated the close interaction between neutrophil activation, neutrophil degranulation, hematopoietic cell lineage, Staphylococcus aureus infection, and periodontitis. Meanwhile, the results also suggested a significant difference for 16 kinds of immune cell compositions between two sample sets. The two potential selected biomarkers (MMP and MPO) had been validated in septic children patients by the ELISA method. Conclusion: This study identified two potential hub gene biomarkers and established a differentially expressed genes-based prediction model for pediatric sepsis, which provided a valuable reference for future clinical research.

Timing of Antibiotic Administration in Pediatric Sepsis

OBJECTIVES

Antibiotic administration within 1 hour of hypotension has been shown to reduce mortality. It is unknown whether antibiotics before hypotension in children who eventually meet criteria for septic shock improves outcomes. This study assesses whether antibiotic timing from the time of meeting criteria for sepsis in children with septic shock impacts morbidity and mortality.

METHODS

This is a retrospective study of children 18 years or younger presenting to a tertiary free-standing children's hospital emergency department with sepsis that subsequently progressed to septic shock and were admitted to an intensive care unit from 2008 to 2012. The time when the patient met criteria for sepsis to the time of first antibiotic administration was assessed and correlated with patient morbidity and mortality.

RESULTS

Among 135 children (median age, 13.1 years), 34 (25%) were previously healthy, whereas 49 (36%) had 2 or more medical comorbidities. Twenty-seven children (20%) had positive blood cultures, 17 (13%) had positive urine cultures, and 34 (25%) had chest x-ray findings that were interpreted as pneumonia. Among the 42 (31%) with antibiotics within 1 hour from criteria for sepsis, there was higher mortality (4/42 vs 0/93, P = 0.009), more organ dysfunction, longer time on a vasoactive infusion, and increased intensive care unit and hospital lengths of stay (all P < 0.05).

CONCLUSIONS

Children with criteria for sepsis who subsequently progressed to septic shock who received antibiotics within 1 hour of meeting sepsis criteria had increased mortality, length of stay, and organ dysfunction.

Epidemiology of Blood Culture Utilization in a Cohort of Critically Ill Children

Blood culture acquisition is integral in the assessment of patients with sepsis, though there exists a lack of clarity relating to clinical states that warrant acquisition. We investigated the clinical status of critically ill children in the timeframe proximate to acquisition of blood cultures. The associated rates of systemic inflammatory response syndrome (72%) and sepsis (57%) with blood culture acquisition were relatively low suggesting a potential overutilization of blood cultures. Efforts are needed to improve decision making at the time that acquisition of blood cultures is under consideration and promote percutaneous blood draws over indwelling lines.

Accelerating Initiation of Adequate Antimicrobial Therapy Using Real-Time Decision Support and Microarray Testing

Introduction:

Bloodstream infections (BSI) represent a common cause of sepsis and mortality in children. Early and adequate empirical antimicrobial therapy is a critical component of successful treatment of BSI. Rapid PCR-based diagnostic technologies, such as nucleic acid microarrays, can decrease the time needed to identify pathogens and antimicrobial resistance and have the potential to ensure patients are started on adequate antibiotics as early as possible. However, without appropriate processes to support timely and targeted interpretation of these results, these advantages may not be realized in practice.

Methods:

Our Antimicrobial Stewardship Program (ASP) implemented a quality improvement initiative using the Institute for Healthcare Improvement’s Model for Improvement to decrease the time between a nucleic acid microarray result for Gram-positive bacteremia and the time a patient was placed on adequate antimicrobial therapy. The primary effective intervention was a near real-time notification system to the managing physicians of inadequate antimicrobial therapy via a call from the ASP team.

Results:

Following the intervention, the average time to adequate antimicrobial therapy in patients with Gram-positive BSI and inadequate coverage decreased from 38 hours with the nucleic acid microarray result alone to 4.7 hours when results were combined with an ASP clinical decision support intervention, an 87% reduction.

Conclusions:

The positive effects of rapid-detection technologies to improve patient care are enhanced when combined with clinical decision support tools that can target inadequate antimicrobial treatments in near real time.

Effectiveness of provider strategies for the early recognition of clinical deterioration due to sepsis in pediatric patients: a systematic review protocol

REVIEW QUESTION

The objective of this review is to determine the effectiveness of provider strategies for the early recognition of clinical deterioration due to sepsis in pediatric patients. Specifically, the review question is: among pediatric, hospitalized patients, up to 18 years of age, what is the effectiveness of clinical assessment compared with use of early recognition screening tools for the recognition of clinical deterioration due to sepsis?

A prospective quality improvement study in the emergency department targeting paediatric sepsis

OBJECTIVE

Quality improvement sepsis initiatives in the paediatric emergency department have been associated with improved processes, but an unclear effect on patient outcome. We aimed to evaluate and improve emergency department sepsis processes and track subsequent changes in patient outcome.

STUDY DESIGN

A prospective observational cohort study in the emergency department of The Royal Children's Hospital, Melbourne. Participants were children aged 0-18 years of age meeting predefined criteria for the diagnosis of sepsis. The following shortcomings in management were identified and targeted in a sepsis intervention: administration of antibiotics and blood sampling for a venous gas at the time of intravenous cannulation, and rapid administration of all fluid resuscitation therapy. The primary outcome measure was hospital length of stay.

RESULTS

102 patients were enrolled pre-intervention, 113 post-intervention. Median time from intravenous cannula insertion to antibiotic administration decreased from 55 min (IQR 27-90 min) pre-intervention to 19 min (IQR 10-32 min) post-intervention (p≤0.01). Venous blood gas at time of first intravenous cannula insertion was performed in 60% of patients pre-intervention vs 79% post-intervention (p≤0.01). Fluids were administered using manual push-pull or pressure-bag methods in 31% of patients pre-intervention and 84% of patients post-intervention (p≤0.01). Median hospital length of stay decreased from 96 h (IQR 64-198 h) pre-intervention to 80 h (IQR 53-167 h) post-intervention (p=0.02). This effect persisted when corrected for unequally distributed confounders between pre-intervention and post-intervention groups (uncorrected HR: 1.36, 95% CI 1.04 to 1.80, p=0.02; corrected HR: 1.34, 95% CI 1.01 to 1.80, p=0.04).

CONCLUSIONS

Use of quality improvement methodologies to improve the management of paediatric sepsis in the emergency department was associated with a reduction in hospital length of stay.
