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

Epinephrine vs Norepinephrine as Initial Treatment in Children With Septic Shock

Importance

There is no consensus and wide practice variation in the choice of initial vasoactive agent in children with septic shock.

Objective

To determine whether receipt of epinephrine compared with norepinephrine as the first vasoactive medication administered is associated with improved outcomes among children with septic shock without known cardiac dysfunction.

Design, Setting, and Participants

This single-center, retrospective cohort study used propensity score matching to examine encounters in which a patient was diagnosed with septic shock and required a vasoactive infusion within 24 hours of ED arrival at a freestanding quaternary care children's hospital. Participants included patients aged 1 month to 18 years who presented to the ED and were diagnosed with septic shock without known cardiac dysfunction and began an epinephrine or norepinephrine infusion within 24 hours of ED arrival between June 1, 2017, and December 31, 2023. Data were analyzed from March 1 to December 31, 2024.

Exposure

Epinephrine vs norepinephrine as the first vasoactive medication received.

Main Outcomes and Measures

The primary outcome was major adverse kidney events by 30 days (MAKE30). Secondary outcomes were 30-day in-hospital mortality, 3-day mortality, need for kidney replacement therapy or persistent kidney dysfunction, endotracheal intubation, mechanical ventilation days, extracorporeal membrane oxygenation, and hospital and intensive care unit length of stay. Primary and secondary outcomes were assessed with the χ2 test of proportions for binary variables and Wilcoxon rank sum test for continuous variables.

Results

Among 231 included encounters, the median (IQR) age was 11.4 (5.6-15.4) years, 126 were female (54.6%), and 142 had a medical history that predisposed them to sepsis (61.5%). Most (147 [63.6%]) initially received an epinephrine infusion and 84 (36.4%) received norepinephrine. In the epinephrine group, 9 of 147 (6.1%) met the outcome of MAKE30 and 6 of 147 (4.1%) died within 30 days. In the norepinephrine group, 3 of 84 (3.6%) met MAKE30 and there were no deaths. After inverse probability of treatment weighting, there were no significant differences in the primary outcome, MAKE30. With 2:1 propensity matching, epinephrine was associated with greater 30-day mortality compared with norepinephrine (3.7% vs 0%; risk difference: 3.7%; 95% CI, 0.2%-7.2%).

Conclusions and Relevance

In this study, those receiving epinephrine had greater 30-day mortality but no difference in MAKE30. Prospective, confirmatory studies are needed to determine if norepinephrine should be the first-line vasoactive agent in pediatric septic shock.

Improving Time to Diagnosis and Management of Pediatric Patients with Acute Neurologic Dysfunction

BACKGROUND

Children presenting to the pediatric emergency department (PED) with neurologic dysfunction require prompt evaluation. Many PEDs successfully implement stroke alerts. However, most pediatric patients presenting with neurologic dysfunction have a non-stroke diagnosis better evaluated using magnetic resonance imaging (MRI). Therefore, we created a Neuro Deterioration clinical pathway using fast MRI to reduce time from PED arrival to completion of radiologic report by 25% in all PED patients presenting with new neurologic dysfunction.

METHODS

After creating an algorithm and allocating resources, the team used quality improvement methodology to implement a Neuro Deterioration clinical pathway. Interventions focused on patient identification, patient flow, and electronic decision support. Statistical process control charting assessed interventions. The primary outcome measure was time from PED arrival to completion of radiologic report. Additional measures included time from arrival to image finish and percentage of patients on pathway.

RESULTS

From 2018 to 2021, time from PED arrival to completion of radiologic report reduced by 32.2%. The average time decrease from a baseline of 211 (n = 287, January 2018-August 2019) to 143 minutes (n = 162, October 2020-December 2021), as noted by a centerline shift on the statistical process control chart. Average time from PED arrival to image finish decreased from 179 to 131 minutes. Percentage of patients on pathway increased. The average age of patients on pathway was 11.5 years, 63.8% were admitted, and 87.5% had a fast MRI for initial imaging. Of the 30.4% of patients with abnormal findings on initial imaging, 85.8% had non-stroke etiologies.

CONCLUSION

The authors created a sustainable Neuro Deterioration clinical pathway to improve time to diagnosis of all pediatric patients with neurologic findings in the PED.

Sepsis Mortality in Hospitalized Children With Cancer Is Associated With Lack of a Screening Tool

OBJECTIVE

Sepsis is associated with significant morbidity and mortality in pediatric hematology, oncology, and transplant (PHOT) patients. This study characterized PHOT patients who developed hospital-onset sepsis more than 12 hours after admission and identified risk factors for 30-day sepsis-attributable (SA) mortality.

PATIENTS AND METHODS

We analyzed an existing multicenter database of sepsis collected prospectively over 5 years (2017-2021) as part of the Improving Pediatric Sepsis Outcomes Collaborative. Sepsis was defined using operational elements documented in the health records based on International Classification of Diseases, Tenth Revision codes, treatment, diagnostic tests, and sepsis screen, huddle, or order set use.

RESULTS

A total of 9604 sepsis episodes in PHOT patients from 49 hospitals were analyzed: 70.5% were identified in the emergency department (ED), 10.9% in inpatient settings less than or equal to 12 hours from admission, and 18.6% were hospital onset. Only 52.5% of patients with hospital-onset sepsis were identified using a sepsis recognition method compared with 87.2% in the ED (P < .001). The overall 30-day SA mortality was 2.2%, with a higher rate (6.9%) among those with hospital-onset sepsis compared with those who developed sepsis at presentation or less than or equal to 12 hours (1.1%, P < .001).

CONCLUSIONS

Although the difference in SA mortality between hospitalized and nonhospitalized patients may be impacted by nonmeasurable confounders inherent to the type of patients presenting in the different care settings, we reported system-based improvements that may reduce mortality. The 30-day SA mortality was lower in hospitalized PHOT patients when sepsis was detected by early recognition methods, supporting the need for efforts to implement sepsis recognition tools in the inpatient setting.

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.

Prolonged Inotrope Use After Surgery for Congenital Heart Disease: A Common Occurrence with a High Burden of Mortality

Outcomes in patients requiring prolonged inotropes (PI) following surgery for congenital heart disease (CHD) have not been well studied. We aimed to describe the burden of PI use in the immediate postoperative period after CHD surgery and identify risk factors for in-hospital mortality. We conducted a retrospective cohort study using the Pediatric Health Information System® (PHIS) database. Patients 0-18 years with CHD who underwent cardiovascular surgery from 2010 to 2020 were included. Patients who received inotropic medications for > 7 consecutive days after surgery were in the PI group and all others in the control group. Patients who died before 7 days were excluded. Multivariable mixed-effect logistic regression was used to examine risk factors for in-hospital mortality. There were 110,271 patients from 48 centers included, 10,292 in the PI group and 99,979 in the control group. In-hospital mortality was significantly higher in the PI group (24.9% vs. 4.6%, p < 0.001). Ventricular assist device use was rare (1.6%). After adjustment, odds of in-hospital mortality in the PI group was 3.5 (95% CI 3.3-3.8) times higher than in controls. Independent risk factors for in-hospital mortality were age, non-White race, class of CHD, number of complex chronic conditions, preoperative inotrope, preoperative extracorporeal membrane oxygenation, sepsis, stroke, renal failure, number of inotropes at 7 days, and discharge year (p < 0.01 for all). Postoperative PI use in CHD is common and carries a considerable burden of mortality. Additional work is needed to understand which risk factors are modifiable and which patients may benefit from reintervention or advanced heart failure therapies.

Delays to Antibiotics in the Emergency Department and Risk of Mortality in Children With Sepsis

Importance

Pediatric consensus guidelines recommend antibiotic administration within 1 hour for septic shock and within 3 hours for sepsis without shock. Limited studies exist identifying a specific time past which delays in antibiotic administration are associated with worse outcomes.

Objective

To determine a time point for antibiotic administration that is associated with increased risk of mortality among pediatric patients with sepsis.

Design, Setting, and Participants

This retrospective cohort study used data from 51 US children's hospitals in the Improving Pediatric Sepsis Outcomes collaborative. Participants included patients aged 29 days to less than 18 years with sepsis recognized within 1 hour of emergency department arrival, from January 1, 2017, through December 31, 2021. Piecewise regression was used to identify the inflection point for sepsis-attributable 3-day mortality, and logistic regression was used to evaluate odds of sepsis-attributable mortality after adjustment for potential confounders. Data analysis was performed from March 2022 to February 2024.

Exposure

The number of minutes from emergency department arrival to antibiotic administration.

Main Outcomes and Measures

The primary outcome was sepsis-attributable 3-day mortality. Sepsis-attributable 30-day mortality was a secondary outcome.

Results

A total of 19 515 cases (median [IQR] age, 6 [2-12] years) were included. The median (IQR) time to antibiotic administration was 69 (47-116) minutes. The estimated time to antibiotic administration at which 3-day sepsis-attributable mortality increased was 330 minutes. Patients who received an antibiotic in less than 330 minutes (19 164 patients) had sepsis-attributable 3-day mortality of 0.5% (93 patients) and 30-day mortality of 0.9% (163 patients). Patients who received antibiotics at 330 minutes or later (351 patients) had 3-day sepsis-attributable mortality of 1.2% (4 patients), 30-day mortality of 2.0% (7 patients), and increased adjusted odds of mortality at both 3 days (odds ratio, 3.44; 95% CI, 1.20-9.93; P = .02) and 30 days (odds ratio, 3.63; 95% CI, 1.59-8.30; P = .002) compared with those who received antibiotics within 330 minutes.

Conclusions and Relevance

In this cohort of pediatric patients with sepsis, 3-day and 30-day sepsis-attributable mortality increased with delays in antibiotic administration 330 minutes or longer from emergency department arrival. These findings are consistent with the literature demonstrating increased pediatric sepsis mortality associated with antibiotic administration delay. To guide the balance of appropriate resource allocation with time for adequate diagnostic evaluation, further research is needed into whether there are subpopulations, such as those with shock or bacteremia, that may benefit from earlier antibiotics.

Prevalence of Low-Acuity Pediatric Emergency Medical Services Transports to a Pediatric Emergency Department in an Urban Area

OBJECTIVES

Many patients transported by Emergency Medical Services (EMS) do not have emergent resource needs. Estimates for the proportion of pediatric EMS calls for low-acuity complaints, and thus potential candidates for alternative dispositions, vary widely and are often based on physician judgment. A more accurate reference standard should include patient assessments, interventions, and dispositions. The objective of this study was to describe the prevalence and characteristics of low-acuity pediatric EMS calls in an urban area.

METHODS

This is a prospective observational study of children transported by EMS to a tertiary care pediatric emergency department. Patient acuity was defined using a novel composite measure that included physiologic assessments, resources used, and disposition. Bivariable and multivariable logistic regression were conducted to assess for factors associated with low-acuity status.

RESULTS

A total of 996 patients were enrolled, of whom 32.9% (95% confidence interval, 30.0-36.0) were low acuity. Most of the sample was Black, non-Hispanic with a mean age of 7 years. When compared with adolescents, children younger than 1 year were more likely to be low acuity (adjusted odds ratio, 3.1 [1.9-5.1]). Patients in a motor vehicle crash were also more likely to be low acuity (adjusted odds ratio, 2.4 [1.2-4.6]). All other variables, including race, insurance status, chief complaint, and dispatch time, were not associated with low-acuity status.

CONCLUSIONS

One third of pediatric patients transported to the pediatric emergency department by EMS in this urban area are for low-acuity complaints. Further research is needed to determine low-acuity rates in other jurisdictions and whether EMS providers can accurately identify low-acuity patients to develop alternative EMS disposition programs for children.

Impact of a Coordinated Sepsis Response on Time to Treatment in a Pediatric Emergency Department

BACKGROUND

Sepsis is responsible for 75 000 pediatric hospitalizations annually, with an associated mortality rate estimated between 11% and 19%. Evidence supports the use of timely fluid resuscitation and antibiotics to decrease morbidity and mortality. Our emergency department did not meet the timeliness goals for fluid and antibiotic administration suggested by the 2012 Surviving Sepsis Campaign.

METHODS

In November 2018, we implemented a sepsis response team utilizing a scripted communication tool and a dedicated sepsis supply cart to address timeliness barriers. Performance was evaluated using statistical process control charts. We conducted observations to evaluate adherence to the new process. Our aim was to meet the Surviving Sepsis Campaign's timeliness goals for first fluid and antibiotic administration (20 and 60 minutes, respectively) within 8 months of our intervention.

RESULTS

We observed sustained decreases in mean time to fluids. We also observed a shift in the proportion of patients receiving fluids within 20 minutes. No shifts were observed for timely antibiotic administration.

CONCLUSIONS

The implementation of a dedicated emergency department sepsis response team with designated roles and responsibilities, directed communication, and easily accessible supplies can lead to improvements in the timeliness of fluid administration in the pediatric population.

Sociodemographic Factors are Associated with Care Delivery and Outcomes in Pediatric Severe Sepsis

IMPORTANCE

Sepsis is a leading cause of morbidity and mortality in the United States and disparate outcomes exist between racial/ethnic groups despite improvements in sepsis management. These observed differences are often related to social determinants of health (SDoH). Little is known about the role of SDoH on outcomes in pediatric sepsis.

OBJECTIVE

This study examined the differences in care delivery and outcomes in children with severe sepsis based on race/ethnicity and neighborhood context (as measured by the social vulnerability index).

DESIGN SETTING AND PARTICIPANTS

This retrospective, cross-sectional study was completed in a quaternary care children's hospital. Patients 18 years old or younger who were admitted between May 1, 2018, and February 28, 2022, met the improving pediatric sepsis outcomes (IPSO) collaborative definition for severe sepsis. Composite measures of social vulnerability, care delivery, and clinical outcomes were stratified by race/ethnicity.

MAIN OUTCOMES AND MEASURES

The primary outcome of interest was admission to the PICU. Secondary outcomes were sepsis recognition and early goal-directed therapy (EGDT).

RESULTS

A total of 967 children met the criteria for IPSO-defined severe sepsis, of whom 53.4% were White/non-Hispanic. Nearly half of the cohort (48.7%) required PICU admission. There was no difference in illness severity at PICU admission by race (1.01 vs. 1.1, p = 0.18). Non-White race/Hispanic ethnicity was independently associated with PICU admission (odds ratio [OR] 1.35 [1.01-1.8], p = 0.04). Although social vulnerability was not independently associated with PICU admission (OR 0.95 [0.59-1.53], p = 0.83), non-White children were significantly more likely to reside in vulnerable neighborhoods (0.66 vs. 0.38, p < 0.001). Non-White race was associated with lower sepsis recognition (87.8% vs. 93.6%, p = 0.002) and less EGDT compliance (35.7% vs. 42.8%, p = 0.024).

CONCLUSIONS AND RELEVANCE

Non-White race/ethnicity was independently associated with PICU admission. Differences in care delivery were also identified. Prospective studies are needed to further investigate these findings.

Multiuser immersive virtual reality simulation for interprofessional sepsis recognition and management

INTRODUCTION

Sepsis is a leading cause of pediatric mortality. While there has been significant effort toward improving adherence to evidence-based care, gaps remain. Immersive multiuser virtual reality (MUVR) simulation may be an approach to enhance provider clinical competency and situation awareness for sepsis.

METHODS

A prospective, observational pilot of an interprofessional MUVR simulation assessing a decompensating patient from sepsis was conducted from January to June 2021. The study objective was to establish validity and acceptability evidence for the platform by assessing differences in sepsis recognition between experienced and novice participants. Interprofessional teams assessed and managed a patient together in the same VR experience with the primary outcome of time to recognition of sepsis utilizing the Situation Awareness Global Assessment Technique analyzed using a logistic regression model. Secondary outcomes were perceived clinical accuracy, relevancy to practice, and side effects experienced.

RESULTS

Seventy-two simulations included 144 participants. The cumulative odds ratio of recognizing sepsis at 2 min into the simulation in comparison to later time points by experienced versus novice providers were significantly higher with a cumulative odds ratio of 3.70 (95% confidence interval: 1.15-9.07, p = .004). Participants agreed that the simulation was clinically accurate (98.6%) and will impact their practice (81.1%), with a high degree of immersion (95.7%-99.3%), and the majority of side effects were perceived as mild (70.4%-81.4%).

CONCLUSIONS

Our novel MUVR simulation demonstrated significant differences in sepsis recognition between experienced and novice participants. This validity evidence along with the data on the simulation's acceptability supports expanded use in training and assessment.

Association between positive blood culture and clinical outcomes among children treated for sepsis in the emergency department

OBJECTIVE

Among children treated for sepsis in a pediatric emergency department (ED), compare clinical features and outcomes between those with blood cultures positive versus negative for a bacterial pathogen.

DESIGN

Single-center retrospective cohort study.

SETTING

Pediatric emergency department (ED) at a quaternary pediatric care center.

PATIENTS

Children aged 0-18 years treated for sepsis defined by the Children's Hospital Association's Improving Pediatric Sepsis Outcomes (IPSO) definition.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

We analyzed 1307 patients treated for sepsis during the study period, of which 117 (9.0%) had blood cultures positive for a bacterial pathogen. Of children with blood culture positive sepsis, 62 (53.0%) had organ dysfunction compared to 514 (43.2%) with culture negative sepsis (adjusted odds ratio 1.56, 95% confidence interval (CI) 1.04-2.34, adjusting for age, high risk medical conditions, and time to antibiotics). Children with blood culture positive sepsis had a larger base deficit, -4 vs -1 (p < 0.01), and higher procalcitonin, 3.84 vs 0.56 ng/mL (p < 0.01).

CONCLUSIONS

Children meeting the IPSO Sepsis definition with blood culture positive for a bacterial pathogen have higher rates of organ dysfunction than those who are culture negative, although our 9% rate of blood culture positivity is lower than previously cited literature from the pediatric intensive care unit.

Antibiotic treatment duration for culture-negative sepsis in the pediatric intensive care unit

Objective

Sepsis remains a leading cause of morbidity and mortality in children. There is very limited guidance for sepsis treatment when cultures remain negative. This study sought to determine the effectiveness of short versus long course of antibiotics when treating culture-negative sepsis and assess for subsequent multidrug-resistant organism (MDRO) acquisition.

Design

Retrospective cohort study.

Setting

Quaternary academic children's hospital.

Patients

Pediatric intensive care unit (ICU) patients with culture-negative sepsis receiving a minimum of 72 hours of antibiotics.

Methods

Patients found to have culture-negative sepsis from January 2017 to May 2020 were divided into two groups: short and long course of antibiotics. Various demographic and laboratory results were collected for each subject as available. Primary outcomes included mortality and lengths of stay. The secondary outcome was subsequent acquisition of a new MDRO.

Results

Eighty-six patients were treated for culture-negative sepsis with 43 patients in both the short- (< or = 7 days) and long-course (>7 days) treatment cohorts. Patients who received a short course of antibiotics had a lower overall mortality than those who received a long course (9.3% vs 25.6% p = 0.047), but there was no difference in 30-day mortality (p > 0.99). Patients in the short-course group had a shorter hospital length of stay (22 vs 30 days p = 0.018). New MDROs were found in 10% of all patients.

Conclusions

Treatment of culture-negative sepsis with short-course antibiotics was not associated with worse outcomes in ICU patients. These findings warrant further investigation with a larger, prospective, multi-center study.

[Time to Antibiotics (TTA) - Reassessment from the German Working Group for Fever and Neutropenia in Children and Adolescents (DGPI/GPOH)]

BACKGROUND

The current German guidance from 2016 recommends a Time to Antibiotics (TTA) of<60 min in children and adolescents with febrile neutropenia (FN).

METHODS

Critical analysis of available studies and recent meta-analyses, and discussion of the practical consequences in the FN working group of the German Societies for Paediatric Oncology and Haematology and Paediatric Infectious Diseases.

RESULTS

The available evidence does not support a clinically significant outcome benefit of a TTA<60 min in all paediatric patients with FN. Studies suggesting such a benefit are biased (mainly triage bias), use different TTA definitions and display further methodical limitations. In any case, a TTA<60 min remains an essential component of the 1st hour-bundle in paediatric cancer patients with septic shock or sepsis with organ dysfunction.

CONCLUSION

Provided that all paediatric FN patients receive a structured medical history and physical examination (including vital signs) by experienced and trained medical personnel in a timely fashion, and provided that a sepsis triage and management bundle is established and implemented, a TTA lower than 3 hours is sufficient and reasonable in stable paediatric cancer patients with FN.

A TRANSCRIPTOMIC APPRECIATION OF CHILDHOOD MENINGOCOCCAL AND POLYMICROBIAL SEPSIS FROM A PRO-INFLAMMATORY AND TRAJECTORIAL PERSPECTIVE, A ROLE FOR VASCULAR ENDOTHELIAL GROWTH FACTOR A AND B MODULATION?

ABSTRACT

This study investigated the temporal dynamics of childhood sepsis by analyzing gene expression changes associated with proinflammatory processes. Five datasets, including four meningococcal sepsis shock (MSS) datasets (two temporal and two longitudinal) and one polymicrobial sepsis dataset, were selected to track temporal changes in gene expression. Hierarchical clustering revealed three temporal phases: early, intermediate, and late, providing a framework for understanding sepsis progression. Principal component analysis supported the identification of gene expression trajectories. Differential gene analysis highlighted consistent upregulation of vascular endothelial growth factor A (VEGF-A) and nuclear factor κB1 (NFKB1), genes involved in inflammation, across the sepsis datasets. NFKB1 gene expression also showed temporal changes in the MSS datasets. In the postmortem dataset comparing MSS cases to controls, VEGF-A was upregulated and VEGF-B downregulated. Renal tissue exhibited higher VEGF-A expression compared with other tissues. Similar VEGF-A upregulation and VEGF-B downregulation patterns were observed in the cross-sectional MSS datasets and the polymicrobial sepsis dataset. Hexagonal plots confirmed VEGF-R (VEGF receptor)-VEGF-R2 signaling pathway enrichment in the MSS cross-sectional studies. The polymicrobial sepsis dataset also showed enrichment of the VEGF pathway in septic shock day 3 and sepsis day 3 samples compared with controls. These findings provide unique insights into the dynamic nature of sepsis from a transcriptomic perspective and suggest potential implications for biomarker development. Future research should focus on larger-scale temporal transcriptomic studies with appropriate control groups and validate the identified gene combination as a potential biomarker panel for sepsis.

Bundled Care to Reduce Sepsis Mortality: The Improving Pediatric Sepsis Outcomes (IPSO) Collaborative

OBJECTIVES

We sought to improve utilization of a sepsis care bundle and decrease 3- and 30- day sepsis-attributable mortality, as well as determine which care elements of a sepsis bundle are associated with improved outcomes.

METHODS

Children's Hospital Association formed a QI collaborative to Improve Pediatric Sepsis Outcomes (IPSO) (January 2017-March 2020 analyzed here). IPSO Suspected Sepsis (ISS) patients were those without organ dysfunction where the provider "intended to treat" sepsis. IPSO Critical Sepsis (ICS) patients approximated those with septic shock. Process (bundle adherence), outcome (mortality), and balancing measures were quantified over time using statistical process control. An original bundle (recognition method, fluid bolus < 20 min, antibiotics < 60 min) was retrospectively compared with varying bundle time-points, including a modified evidence-based care bundle, (recognition method, fluid bolus < 60 min, antibiotics < 180 min). We compared outcomes using Pearson χ-square and Kruskal Wallis tests and adjusted analysis.

RESULTS

Reported are 24 518 ISS and 12 821 ICS cases from 40 children's hospitals (January 2017-March 2020). Modified bundle compliance demonstrated special cause variation (40.1% to 45.8% in ISS; 52.3% to 57.4% in ICS). The ISS cohort's 30-day, sepsis-attributable mortality dropped from 1.4% to 0.9%, a 35.7% relative reduction over time (P < .001). In the ICS cohort, compliance with the original bundle was not associated with a decrease in 30-day sepsis-attributable mortality, whereas compliance with the modified bundle decreased mortality from 4.75% to 2.4% (P < .01).

CONCLUSIONS

Timely treatment of pediatric sepsis is associated with reduced mortality. A time-liberalized care bundle was associated with greater mortality reductions.

A sepsis trigger tool reduces time to antibiotic administration in the NICU

OBJECTIVE

Prolonged time to antibiotic administration is associated with increased morbidity and mortality. Interventions to decrease the time to antibiotic administration may improve mortality and morbidity.

STUDY DESIGN

We identified possible change concepts for reducing time to antibiotic usage in the NICU. For the initial intervention, we developed a sepsis screening tool based on NICU-specific parameters. The main goal of the project was to reduce time to antibiotic administration by 10%.

RESULTS

The project was conducted from April 2017 until April 2019. There were no missed cases of sepsis in the project period. Time to antibiotic administration for patients who were started on antibiotics decreased during the project, with the mean shifting from 126 to 102 min, a reduction of 19%.

CONCLUSIONS

We successfully reduced time to antibiotic delivery in our NICU using a trigger tool to identifying potential cases of sepsis in the NICU environment. The trigger tool requires broader validation.

Implementation of a Virtual Interprofessional ICU Learning Collaborative: Successes, Challenges, and Initial Reactions From the Structured Team-Based Optimal Patient-Centered Care for Virus COVID-19 Collaborators

Initial Society of Critical Care Medicine Discovery Viral Infection and Respiratory illness Universal Study (VIRUS) Registry analysis suggested that improvements in critical care processes offered the greatest modifiable opportunity to improve critically ill COVID-19 patient outcomes.

OBJECTIVES

The Structured Team-based Optimal Patient-Centered Care for Virus COVID-19 ICU Collaborative was created to identify and speed implementation of best evidence based COVID-19 practices.

DESIGN SETTING AND PARTICIPANTS

This 6-month project included volunteer interprofessional teams from VIRUS Registry sites, who received online training on the Checklist for Early Recognition and Treatment of Acute Illness and iNjury approach, a structured and systematic method for delivering evidence based critical care. Collaborators participated in weekly 1-hour videoconference sessions on high impact topics, monthly quality improvement (QI) coaching sessions, and received extensive additional resources for asynchronous learning.

MAIN OUTCOMES AND MEASURES

Outcomes included learner engagement, satisfaction, and number of QI projects initiated by participating teams.

RESULTS

Eleven of 13 initial sites participated in the Collaborative from March 2, 2021, to September 29, 2021. A total of 67 learners participated in the Collaborative, including 23 nurses, 22 physicians, 10 pharmacists, nine respiratory therapists, and three nonclinicians. Site attendance among the 11 sites in the 25 videoconference sessions ranged between 82% and 100%, with three sites providing at least one team member for 100% of sessions. The majority reported that topics matched their scope of practice (69%) and would highly recommend the program to colleagues (77%). A total of nine QI projects were initiated across three clinical domains and focused on improving adherence to established critical care practice bundles, reducing nosocomial complications, and strengthening patient- and family-centered care in the ICU. Major factors impacting successful Collaborative engagement included an engaged interprofessional team; an established culture of engagement; opportunities to benchmark performance and accelerate institutional innovation, networking, and acclaim; and ready access to data that could be leveraged for QI purposes.

CONCLUSIONS AND RELEVANCE

Use of a virtual platform to establish a learning collaborative to accelerate the identification, dissemination, and implementation of critical care best practices for COVID-19 is feasible. Our experience offers important lessons for future collaborative efforts focused on improving ICU processes of care.

Less is more: Antibiotics at the beginning of life

Antibiotic exposure at the beginning of life can lead to increased antimicrobial resistance and perturbations of the developing microbiome. Early-life microbiome disruption increases the risks of developing chronic diseases later in life. Fear of missing evolving neonatal sepsis is the key driver for antibiotic overtreatment early in life. Bias (a systemic deviation towards overtreatment) and noise (a random scatter) affect the decision-making process. In this perspective, we advocate for a factual approach quantifying the burden of treatment in relation to the burden of disease balancing antimicrobial stewardship and effective sepsis management.

Implementing Pediatric Surviving Sepsis Campaign Guidelines: Improving Compliance With Lactate Measurement in the PICU

The 2020 pediatric Surviving Sepsis Campaign (pSSC) recommends measuring lactate during the first hour of resuscitation for severe sepsis/shock. We aimed to improve compliance with this recommendation for patients who develop severe sepsis/shock while admitted to the PICU.

DESIGN

Structured, quality improvement initiative.

SETTING

Single-center, 26-bed, quaternary-care PICU.

PATIENTS

All patients with PICU-onset severe sepsis/shock from December 2018 to December 2021.

INTERVENTIONS

Creation of a multidisciplinary local sepsis improvement team, education program targeting frontline providers (nurse practitioners, resident physicians), and peer-to-peer nursing education program with feedback to key stakeholders.

MEASUREMENTS AND MAIN RESULTS

The primary outcome measure was compliance with obtaining a lactate measurement within 60 minutes of the onset of severe sepsis/shock originating in our PICU using a local Improving Pediatric Sepsis Outcomes database and definitions. The process measure was time to first lactate measurement. Secondary outcomes included number of IV antibiotic days, number of vasoactive days, number of ICU days, and number of ventilator days. A total of 166 unique PICU-onset severe sepsis/shock events and 156 unique patients were included. One year after implementation of our first interventions with subsequent Plan-Do-Study-Act cycles, overall compliance increased from 38% to 47% (24% improvement) and time to first lactate decreased from 175 to 94 minutes (46% improvement). Using a statistical process control I chart, the preshift mean for time to first lactate measurement was noted to be 179 minutes and the postshift mean was noted to be 81 minutes demonstrating a 55% improvement.

CONCLUSIONS

This multidisciplinary approach led to improvement in time to first lactate measurement, an important step toward attaining our target of lactate measurement within 60 minutes of septic shock identification. Improving compliance is necessary for understanding implications of the 2020 pSSC guidelines on sepsis morbidity and mortality.

Screening for Social Determinants of Health in the Pediatric Intensive Care Unit: Recommendations for Clinicians

Social determinants of health (SDoH) play a significant role in the health and well-being of children in the United States. Disparities in the risk and outcomes of critical illness have been extensively documented but are yet to be fully explored through the lens of SDoH. In this review, we provide justification for routine SDoH screening as a critical first step toward understanding the causes of, and effectively addressing health disparities affecting critically ill children. Second, we summarize important aspects of SDoH screening that need to be considered before implementing this practice in the pediatric critical care setting.

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.

Utilizing big data from electronic health records in pediatric clinical care

Big data has the capacity to transform both pediatric healthcare delivery and research, but its potential has yet to be fully realized. Curation of large multi-institutional datasets of high-quality data has allowed for significant advances in the timeliness of quality improvement efforts. Improved access to large datasets and computational power have also paved the way for the development of high-performing, data-driven decision support tools and precision medicine approaches. However, implementation of these approaches and tools into pediatric practice has been hindered by challenges in our ability to adequately capture the heterogeneity of the pediatric population as well as the nuanced complexities of pediatric diseases such as sepsis. Moreover, there are large gaps in knowledge and definitive evidence demonstrating the utility, usability, and effectiveness of these types of tools in pediatric practice, which presents significant challenges to provider willingness to leverage these solutions. The next wave of transformation for pediatric healthcare delivery and research through big data and sophisticated analytics will require focusing efforts on strategies to overcome cultural barriers to adoption and acceptance. IMPACT: Big data from EHRs can be used to drive improvement in pediatric clinical care. Clinical decision support, artificial intelligence, machine learning, and precision medicine can transform pediatric care using big data from the EHR. This article provides a review of barriers and enablers for the effective use of data analytics in pediatric clinical care using pediatric sepsis as a use case. The impact of this review is that it will inform influencers of pediatric care about the importance of current trends in data analytics and its use in improving outcomes of care through EHR-based strategies.

Characteristics and Outcomes of Sepsis Presenting in Inpatient Pediatric Settings

OBJECTIVE

The pediatric sepsis literature lacks studies examining the inpatient setting, yet sepsis remains a leading cause of death in children's hospitals. More information is needed about sepsis arising in patients already hospitalized to improve morbidity and mortality outcomes. This study describes the clinical characteristics, process measures, and outcomes of inpatient sepsis cases compared with emergency department (ED) sepsis cases within the Improving Pediatric Sepsis Outcomes data registry from 46 hospitals that care for children.

METHODS

This retrospective cohort study included Improving Pediatric Sepsis Outcomes sepsis cases from January 2017 to December 2019 with onset in inpatient or ED. We used descriptive statistics to compare inpatient and ED sepsis metrics and describe inpatient sepsis outcomes.

RESULTS

The cohort included 26 855 cases; 8.4% were inpatient and 91.6% were ED. Inpatient cases had higher sepsis-attributable mortality (2.0% vs 1.4%, P = .025), longer length of stay after sepsis recognition (9 vs 5 days, P <.001), more intensive care admissions (57.6% vs 54.1%, P = .002), and greater average vasopressor use (18.0% vs 13.6%, P <.001) compared with ED. In the inpatient cohort, >40% of cases had a time from arrival to recognition within 12 hours. In 21% of cases, this time was >96 hours. Improved adherence to sepsis treatment bundles over time was associated with improved 30-day sepsis-attributable mortality for inpatients with sepsis.

CONCLUSIONS

Inpatient sepsis cases had longer lengths of stay, more need for intensive care, and higher vasopressor use. Sepsis-attributable mortality was significantly higher in inpatient cases compared with ED cases and improved with improved sepsis bundle adherence.

Identification of sepsis in paediatric emergency departments: A scoping review

AIM

Sepsis is an acute illness associated with significant morbidity and mortality. Early detection and time-sensitive management of sepsis has been shown to improve outcomes. We report the results of a scoping review to explore methods evaluated for the identification of sepsis in children presenting to emergency departments.

METHODS

A systematic literature search was carried out on two databases, Medline and Web of Science, to identify relevant studies published from 1990 to 2022. Data were extracted for age groups including study design, reference standard used for comparison, sepsis identification method evaluated and study quality.

RESULTS

A total of 89 studies were identified from the literature search. There was significant heterogeneity in the age groups including study design and reference standards used for evaluating the performance of the sepsis identification methods. There has been a substantial increase in the number of published studies in the last 2 years.

CONCLUSION

Our scoping review identifies marked heterogeneity in approaches to identifying sepsis but demonstrates a recent focus of research on patient outcomes. Using appropriate core outcome sets, developing reference standards, monitoring sepsis prevalence via registries and continuously monitoring process measures will provide robust evidence to identify the best performing identification tools and the impact they have on patient-orientated outcomes.

Implementation of an Automated Sepsis Screening Tool in a Children's Hospital Emergency Department: A Cost Analysis

OBJECTIVE

To determine the effect of implementation of an automated sepsis screening tool on the median cost of affected patient encounters.

STUDY DESIGN

This retrospective cohort study used propensity score-matched comparison groups to assess the difference in median cost for comparable affected patient encounters before and after the implementation of an automated sepsis screening tool in a large US children's hospital emergency department (ED) with >90 000 annual visits. All patient encounters in 2018 impacted by the automated sepsis screening tool were included and compared with a propensity score-matched comparison group drawn from patient encounters in 2012 that might have been affected by the screening tool had it been active at that time. The main outcome was the change in the median cost for comparable affected patient encounters.

RESULTS

The overall median cost for those affected by an automated sepsis screening tool decreased by 21.2%, from $6454 (IQR, $968-$21 697) to $5084 (IQR, $802-$16 618). The median cost for encounters with an associated International Classification of Diseases sepsis code decreased by 51.1%, from $58 685 (IQR, $32 224-$134 895) to $28 672 (IQR, $16 796-$60 657).

CONCLUSIONS

The median cost for comparable patient encounters decreased with implementation of an automated sepsis screening tool in the pediatric ED. Costs were decreased even more substantially for patients with sepsis. In addition to improving outcomes, an automated sepsis screening tool appears to be at least cost-effective and may be cost-saving, an incentive for more widespread use of this technology.

"These Are Our Kids": Qualitative Interviews With Clinical Leaders in General Emergency Departments on Motivations, Processes, and Guidelines in Pediatric Sepsis Care

STUDY OBJECTIVE

Sepsis is a leading cause of pediatric death requiring emergency resuscitation. Most children with sepsis are treated in general emergency departments (EDs); however, research has focused on pediatric EDs. We sought to identify barriers and facilitators to pediatric sepsis care in general EDs, including care processes, the role of guidelines, and incentivized metrics.

METHODS

In this qualitative study, we conducted semistructured interviews with key informant physician and nurse leaders overseeing pediatric sepsis in general EDs in 2021, including medical directors, nurse managers, and quality coordinators. Interviews were audio-recorded, transcribed, and coded using deductive domains based on steps of sepsis care, pediatric readiness, and structural dynamics. Domains were analyzed across interviews in matrices, using thematic analysis within domains.

RESULTS

Twenty-one clinical leaders representing 26 hospitals, including trauma levels I to IV, were interviewed. The themes included the following: (1) motivation to improve pediatric sepsis care based on moral imperative and location; (2) need for actionable pediatric sepsis guidelines; (3) children's hospitals' role in education, protocols, transfer, and consultation; and (4) mixed feelings about reportable metrics, particularly in EDs with low pediatric volume. Sepsis care process challenges included diagnosis, intravenous access, and antibiotic delivery but varied among hospitals.

CONCLUSION

Leaders in general EDs were motivated to provide high-quality pediatric sepsis care but disagreed on whether reportable metrics would drive improvements. They universally sought direct support from their nearest children's hospitals and actionable guidelines. Efforts to address pediatric sepsis quality in general EDs should prioritize guideline design, responsive pediatric transfer and consultation systems, and locally specific process improvement.

Beyond Vital Signs: Pediatric Sepsis Screening that Includes Organ Failure Assessment Detects Patients with Worse Outcomes

Pediatric sepsis screening is recommended. The 2005 Goldstein criteria, the basis of our institutional sepsis screening tool (ISST), correlate poorly with clinically diagnosed sepsis. The study objective was to retrospectively evaluate the ISST sensitivity compared with the Pediatric Sequential Organ Failure Assessment (pSOFA). This was a single-center retrospective cohort study. The primary outcome was pSOFA score and ISST sensitivity for severe sepsis. Secondary outcomes included clinical outcome measures. In this severe sepsis cohort (N = 491), pSOFA and ISST sensitivity were 57.6 and 61.1%, respectively. In regression analysis for a positive pSOFA, positive blood culture (odds ratio [OR] 2.2, 95% confidence interval [CI] 1.1–4.3, p = 0.025), older age (OR 1.006, 95% CI 1.003–1.009, p < 0.001), and pulmonary infectious source (OR 3.3, 95% CI 1.6–6.5, p = 0.001) demonstrated independent association. In regression analysis for a positive ISST, older age (OR 1.003, 95% CI 1–1.006, p = 0.031) and intra-abdominal infectious source (OR 0.3, 95% CI 0.1–0.8, p = 0.014) demonstrated independent association. A negative ISST was associated with higher intensive care unit (ICU) admission prevalence (p = 0.01) and fewer ICU-free days (p = 0.018). A positive pSOFA score was associated with higher ICU admission prevalence, vasopressor requirement, and vasopressor days as well as fewer ICU, hospital, and mechanical ventilation-free days (all p < 0.001). Exploratory analysis combining the ISST and pSOFA into a hybrid screen demonstrated superior sensitivity (84.3%) and outcome discrimination. The pSOFA demonstrated noninferior sensitivity to a Goldstein-based institutional sepsis screening model. Further, pSOFA was a better discriminator of poor clinical outcomes. An exploratory hybrid screening model shows superior performance but will require prospective study.

The Current and Future State of Pediatric Sepsis Definitions: An International Survey

BACKGROUND AND OBJECTIVES

Definitions for pediatric sepsis were established in 2005 without data-driven criteria. It is unknown whether the more recent adult Sepsis-3 definitions meet the needs of providers caring for children. We aimed to explore the use and applicability of criteria to diagnose sepsis and septic shock in children across the world.

METHODS

This is an international electronic survey of clinicians distributed across international and national societies representing pediatric intensive care, emergency medicine, pediatrics, and pediatric infectious diseases. Respondents stated their preferences on a 5-point Likert scale.

RESULTS

There were 2835 survey responses analyzed, of which 48% originated from upper-middle income countries, followed by high income countries (38%) and low or lower-middle income countries (14%). Abnormal vital signs, laboratory evidence of inflammation, and microbiologic diagnoses were the criteria most used for the diagnosis of "sepsis." The 2005 consensus definitions were perceived to be the most useful for sepsis recognition, while Sepsis-3 definitions were stated as more useful for benchmarking, disease classification, enrollment into trials, and prognostication. The World Health Organization definitions were perceived as least useful across all domains. Seventy one percent of respondents agreed that the term sepsis should be restricted to children with infection-associated organ dysfunction.

CONCLUSIONS

Clinicians around the world apply a myriad of signs, symptoms, laboratory studies, and treatment factors when diagnosing sepsis. The concept of sepsis as infection with associated organ dysfunction is broadly supported. Currently available sepsis definitions fall short of the perceived needs. Future diagnostic algorithms should be pragmatic and sensitive to the clinical settings.

Computerized Clinical Decision Support Systems for the Early Detection of Sepsis Among Pediatric, Neonatal, and Maternal Inpatients: Scoping Review

BACKGROUND

Sepsis is a severe condition associated with extensive morbidity and mortality worldwide. Pediatric, neonatal, and maternal patients represent a considerable proportion of the sepsis burden. Identifying sepsis cases as early as possible is a key pillar of sepsis management and has prompted the development of sepsis identification rules and algorithms that are embedded in computerized clinical decision support (CCDS) systems.

OBJECTIVE

This scoping review aimed to systematically describe studies reporting on the use and evaluation of CCDS systems for the early detection of pediatric, neonatal, and maternal inpatients at risk of sepsis.

METHODS

MEDLINE, Embase, CINAHL, Cochrane, Latin American and Caribbean Health Sciences Literature (LILACS), Scopus, Web of Science, OpenGrey, ClinicalTrials.gov, and ProQuest Dissertations and Theses Global (PQDT) were searched by using a search strategy that incorporated terms for sepsis, clinical decision support, and early detection. Title, abstract, and full-text screening was performed by 2 independent reviewers, who consulted a third reviewer as needed. One reviewer performed data charting with a sample of data. This was checked by a second reviewer and via discussions with the review team, as necessary.

RESULTS

A total of 33 studies were included in this review-13 (39%) pediatric studies, 18 (55%) neonatal studies, and 2 (6%) maternal studies. All studies were published after 2011, and 27 (82%) were published from 2017 onward. The most common outcome investigated in pediatric studies was the accuracy of sepsis identification (9/13, 69%). Pediatric CCDS systems used different combinations of 18 diverse clinical criteria to detect sepsis across the 13 identified studies. In neonatal studies, 78% (14/18) of the studies investigated the Kaiser Permanente early-onset sepsis risk calculator. All studies investigated sepsis treatment and management outcomes, with 83% (15/18) reporting on antibiotics-related outcomes. Usability and cost-related outcomes were each reported in only 2 (6%) of the 31 pediatric or neonatal studies. Both studies on maternal populations were short abstracts.

CONCLUSIONS

This review found limited research investigating CCDS systems to support the early detection of sepsis among pediatric, neonatal, and maternal patients, despite the high burden of sepsis in these vulnerable populations. We have highlighted the need for a consensus definition for pediatric and neonatal sepsis and the study of usability and cost-related outcomes as critical areas for future research.

Medication and Fluid Management of Pediatric Sepsis and Septic Shock

Sepsis is a life-threatening response to infection that contributes significantly to neonatal and pediatric morbidity and mortality worldwide. The key tenets of care include early recognition of potential sepsis, rapid intervention with appropriate fluids to restore adequate tissue perfusion, and empiric antibiotics to cover likely pathogens. Vasoactive/inotropic agents are recommended if tissue perfusion and hemodynamics are inadequate following initial fluid resuscitation. Several adjunctive therapies have been suggested with theoretical benefit, though definitive recommendations are not yet supported by research reports. This review focuses on the recommendations for medication and fluid management of pediatric sepsis and septic shock, highlighting issues related to antibiotic choices and antimicrobial stewardship, selection of intravenous fluids for resuscitation, and selection and use of vasoactive/inotropic medications. Controversy remains regarding resuscitation fluid volume and type, antibiotic choices depending upon infectious risks in the patient's community, and adjunctive therapies such as vitamin C, corticosteroids, intravenous immunoglobulin, and methylene blue. We include best practice recommendations based on international guidelines, a review of primary literature, and a discussion of ongoing clinical trials and the nuances of therapeutic choices.

Pediatric sepsis screening in US hospitals

Sepsis is a major cause of morbidity and mortality in children. While adverse outcomes can be reduced through prompt initiation of sepsis protocols including fluid resuscitation and antibiotics, provision of these therapies relies on clinician recognition of sepsis. Recognition is challenging in children because early signs of shock such as tachycardia and tachypnea have low specificity while hypotension often does not occur until late in the clinical course. This narrative review highlights the important context that has led to the rapid growth of pediatric sepsis screening in the United States. In this review, we (1) describe different screening tools used in US emergency department, inpatient, and intensive care unit settings; (2) highlight details of the design, implementation, and evaluation of specific tools; (3) review the available data on the process of integrating sepsis screening into an overall sepsis quality improvement program and on the effect of these screening tools on patient outcomes; (4) discuss potential harms of sepsis screening including alarm fatigue; and (5) highlight several future directions in sepsis screening, such as novel tools that incorporate artificial intelligence and machine learning methods to augment sepsis identification with the ultimate goal of precision-based approaches to sepsis recognition and treatment. IMPACT: This narrative review highlights the context that has led to the rapid growth of pediatric sepsis screening nationally. Screening tools used in US emergency department, inpatient, and intensive care unit settings are described in terms of their design, implementation, and clinical performance. Limitations and potential harms of these tools are highlighted, as well as future directions that may lead to a more precision-based approach to sepsis recognition and treatment.

Using Aggregate Vasoactive-Inotrope Scores to Predict Clinical Outcomes in Pediatric Sepsis

OBJECTIVES

The heterogeneity of sepsis makes it difficult to predict outcomes using existing severity of illness tools. The vasoactive-inotrope score (VIS) is a quantitative measure of the amount of vasoactive support required by patients. We sought to determine if a higher aggregate VIS over the first 96 h of vasoactive medication initiation is associated with increased resource utilization and worsened clinical outcomes in pediatric patients with severe sepsis.

DESIGN

Retrospective cohort study.

SETTING

Single-center at Children's Wisconsin in Milwaukee, WI.

PATIENTS

One hundred ninety-nine pediatric patients, age less than 18 years old, diagnosed with severe sepsis, receiving vasoactive medications between January 2017 and July 2019.

INTERVENTIONS

Retrospective data obtained from the electronic medical record, calculating VIS at 2 h intervals from 0-12 h and at 4 h intervals from 12-96 h from Time 0.

MEASUREMENTS

Aggregate VIS derived from the hourly VIS area under the curve (AUC) calculation based on the trapezoidal rule. Data were analyzed using Pearson's correlations, Mann-Whitney test, Wilcoxon signed rank test, and classification, and regression tree (CART) analyses.

MAIN RESULTS

Higher aggregate VIS is associated with longer hospital LOS (p < 0.0001), PICU LOS (p < 0.0001), MV days (p = 0.018), increased in-hospital mortality (p < 0.0001), in-hospital cardiac arrest (p = 0.006), need for ECMO (p < 0.0001), and need for CRRT (p < 0.0001). CART analyses found that aggregate VIS >20 is an independent predictor for in-hospital mortality (p < 0.0001) and aggregate VIS >16 for ECMO use (p < 0.0001).

CONCLUSIONS

There is a statistically significant association between aggregate VIS and many clinical outcomes, allowing clinicians to utilize aggregate VIS as a physiologic indicator to more accurately predict disease severity/trajectory in pediatric sepsis.

An Acute Care Sepsis Response System Targeting Improved Antibiotic Administration

BACKGROUND AND OBJECTIVES

Pediatric sepsis quality improvement in emergency departments has been well described and associated with improved survival. Acute care (non-ICU inpatient) units differ in important ways, and optimal approaches to improving sepsis processes and outcomes in this setting are not yet known. Our objective was to increase the proportion of acute care sepsis cases in our health system with initial antibiotic order-to-administration time ≤60 minutes by 20% from a baseline of 43% to 52% by December 2020.

METHODS

Employing the Model for Improvement with broad stakeholder engagement, we developed and implemented interventions aimed at effective intervention for sepsis cases on acute care units. We analyzed process and outcome metrics over time using statistical process control charts. We used descriptive statistics to explore differences in antibiotic order-to-administration time and inform ongoing improvement.

RESULTS

We cared for 187 patients with sepsis over the course of our initiative. The proportion within our goal antibiotic order-to-administration time rose from 43% to 64% with evidence of special cause variation after our interventions. Of all patients, 66% experienced ICU transfer and 4% died.

CONCLUSIONS

We successfully decreased antibiotic order-to-administration time. We also introduced a novel model for sepsis response systems that integrates interventions designed for the complexities of acute care settings. We demonstrated impactful local improvements in the acute care setting where quality improvement reports and success have previously been limited.

Evaluation of a Sepsis Alert in the Pediatric Acute Care Setting

BACKGROUND

Severe sepsis can cause significant morbidity and mortality in pediatric patients. Early recognition and treatment are vital to improving patient outcomes.

OBJECTIVE

The study aimed to evaluate the impact of a best practice alert in improving recognition of sepsis and timely treatment to improve mortality in the pediatric acute care setting.

METHODS

A multidisciplinary team adapted a sepsis alert from the emergency room setting to facilitate identification of sepsis in acute care pediatric inpatient areas. The sepsis alert included clinical decision support to aid in timely treatment, prompting the use of intravenous fluid boluses, and antibiotic administration. We compared sepsis-attributable mortality, time to fluid and antibiotic administration, proportion of patients who required transfer to a higher level of care, and antibiotic days for the year prior to the sepsis alert (2017) to the postimplementation phase (2019).

RESULTS

We had 79 cases of severe sepsis in 2017 and 154 cases in 2019. Of these, we found an absolute reduction in both 3-day sepsis-attributable mortality (2.53 vs. 0%) and 30-day mortality (3.8 vs. 1.3%) when comparing the pre- and postintervention groups. Though our analysis was underpowered due to small sample size, we also identified reductions in median time to fluid and antibiotic administration, proportion of patients who were transferred to the intensive care unit, and no observable increase in antibiotic days.

CONCLUSION

Electronic sepsis alerts may assist in improving recognition of sepsis and support timely antibiotic and fluid administration in pediatric acute care settings.

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

BACKGROUND

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.

METHODS

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.

RESULTS

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 <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.

CONCLUSIONS

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.

Therapeutic approaches to pediatric COVID-19: an online survey of pediatric rheumatologists

Data on therapy of COVID-19 in immunocompetent and immunosuppressed children are scarce. We aimed to explore management strategies of pediatric rheumatologists. All subscribers to international Pediatric Rheumatology Bulletin Board were invited to take part in an online survey on therapeutic approaches to COVID-19 in healthy children and children with autoimmune/inflammatory diseases (AID). Off-label therapies would be considered by 90.3% of the 93 participating respondents. In stable patients with COVID-19 on oxygen supply (stage I), use of remdesivir (48.3%), azithromycin (26.6%), oral corticosteroids (25.4%) and/or hydroxychloroquine (21.9%) would be recommended. In case of early signs of "cytokine storm" (stage II) or in critically ill patients (stage III) (a) anakinra (79.5% stage II; 83.6% stage III) or tocilizumab (58.0% and 87.0%, respectively); (b) corticosteroids (oral 67.2% stage II, intravenously 81.7% stage III); (c) intravenous immunoglobulins (both stages 56.5%); or (d) remdesivir (both stages 46.7%) were considered. In AID, > 94.2% of the respondents would not support a preventive adaptation of the immunomodulating therapy. In case of mild COVID-19, more than 50% of the respondents would continue pre-existing treatment with immunoglobulins (100%), hydroxychloroquine (94.2%), anakinra (79.2%) or canakinumab (72.5%), or tocilizumab (69.8%). Long-term corticosteroids would be reduced by 26.9% (< = 2 mg/kg/d) and 50.0% (> 2 mg/kg/day), respectively, with only 5.8% of respondents voting to discontinue the therapy. Conversely, more than 75% of respondents would refrain from administering cyclophosphamide and anti-CD20-antibodies. As evidence on management of pediatric COVID-19 is incomplete, continuous and critical expert opinion and knowledge exchange is helpful.

Comparison of children receiving emergent sepsis care by mode of arrival

OBJECTIVE

To determine if differences in patient characteristics, treatments, and outcomes exist between children with sepsis who arrive by emergency medical services (EMS) versus their own mode of transport (self-transport).

METHODS

Retrospective cohort study of patients who presented to the Emergency Department (ED) of two large children's hospitals and treated for sepsis from November 2013 to June 2017. Presentation, ED treatment, and outcomes, primarily time to first bolus and first parental antibiotic, were compared between those transported via EMS versus patients who were self-transported.

RESULTS

Of the 1813 children treated in the ED for sepsis, 1452 were self-transported and 361 were transported via EMS. The EMS group were more frequently male, of black race, and publicly insured than the self-transport group. The EMS group was more likely to have a critical triage category, receive initial care in the resuscitation suite (51.9 vs. 22%), have hypotension at ED presentation (14.4 vs. 5.4%), lactate >2.0 mmol/L (60.6 vs. 40.8%), vasoactive agents initiated in the ED (8.9 vs. 4.9%), and to be intubated in the ED (14.4 vs. 2.8%). The median time to first IV fluid bolus was faster in the EMS group (36 vs. 57 min). Using Cox LASSO to adjust for potential covariates, time to fluids remained faster for the EMS group (HR 1.26, 95% CI 1.12, 1.42). Time to antibiotics, ICU LOS, 3- or 30-day mortality rates did not differ, yet median hospital LOS was significantly longer in those transported by EMS versus self-transported (6.5 vs. 5.3 days).

CONCLUSIONS

Children with sepsis transported by EMS are a sicker population of children than those self-transported on arrival and had longer hospital stays. EMS transport was associated with earlier in-hospital fluid resuscitation but no difference in time to first antibiotic. Improved prehospital recognition and care is needed to promote adherence to both prehospital and hospital-based sepsis resuscitation benchmarks.

Barriers and Proposed Solutions to a Successful Implementation of Pediatric Sepsis Protocols

The implementation of managed protocols contributes to a systematized approach to the patient and continuous evaluation of results, focusing on improving clinical practice, early diagnosis, treatment, and outcomes. Advantages to the adoption of a pediatric sepsis recognition and treatment protocol include: a reduction in time to start fluid and antibiotic administration, decreased kidney dysfunction and organ dysfunction, reduction in length of stay, and even a decrease on mortality. Barriers are: absence of a written protocol, parental knowledge, early diagnosis by healthcare professionals, venous access, availability of antimicrobials and vasoactive drugs, conditions of work, engagement of healthcare professionals. There are challenges in low-middle-income countries (LMIC). The causes of sepsis and resources differ from high-income countries. Viral agent such as dengue, malaria are common in LMIC and initial approach differ from bacterial infections. Some authors found increased or no impact in mortality or increased length of stay associated with the implementation of the SCC sepsis bundle which reinforces the importance of adapting it to most frequent diseases, disposable resources, and characteristics of healthcare professionals. Conclusions: (1) be simple; (2) be precise; (3) education; (5) improve communication; (5) work as a team; (6) share and celebrate results.
