Sepsis is a leading cause of preventable harm in children. Sepsis pathways reduce time to antibiotics in suspected sepsis but risk unnecessary antibiotics in children with non-bacterial infections. We estimate the impact of a statewide paediatric sepsis pathway implementation on antibiotic appropriateness and consumption in Queensland, Australia. ‘Before-and-after’ comparison of antibiotic appropriateness and consumption in children with suspected sepsis in three dedicated paediatric Emergency Departments (EDs). Children suspected of sepsis presenting to EDs between April 1st and December 31st 2019 were compared with a sample attending the EDs in 2017, before pathway implementation. Outcome measures included the proportion of children receiving appropriate empiric antibiotic choice and dose. We additionally performed time series analysis of all antibiotic prescriptions in the tertiary children’s ED. 1852 children underwent sepsis evaluation following pathway implementation and were compared with 523 historical controls. The proportion with appropriate empiric antibiotic choice and dosing increased after pathway introduction (adjusted relative risk [aRR] 1.33; 95

Background Sepsis affects 25 million children and neonates annually, causing significant mortality and morbidity. Early identification and treatment are crucial for improving outcomes. Identifying children at risk is challenging due to clinical heterogeneity and overlap with other conditions. Current evaluations of sepsis criteria adopt a variable-centred approach, evaluating each criterion independently. The objective of this study was to explore associations between patterns of sepsis screening criteria and sepsis risk in children screened in the emergency department (ED) to identify distinct profiles that describe the clinical heterogeneity of suspected sepsis. Methods This secondary analysis involved 3473 children screened for sepsis across 12 EDs in Queensland, Australia. Bayesian profile regression was used to construct data-driven clinical profiles derived from sepsis screening criteria and their association with suspected sepsis, defined as senior medical officer diagnosis and antibiotic administration in the ED. Posterior risk probabilities (Prs) with 95% credible intervals (CIs) were calculated for each profile. Profiles were internally validated by assessing their association with sepsis, septic shock, organ dysfunction and infection sources, in both adjusted and unadjusted models. Results Seven distinct clinical profiles were identified. Two profiles were labelled as high risk of suspected sepsis (profile 1, n=22: Pr 0.73, 95% CI 0.55, 0.89; profile 2, n=150: Pr 0.69, 95% CI 0.59, 0.80), four as moderate risk and one as low risk. High-risk profiles were characterised by severe illness indicators and elevated lactate levels. Moderate-risk profiles included criteria such as altered behaviour, young age (<3 months) and respiratory distress. High-risk profiles had strong associations with all clinical outcomes. Conclusions Seven clinical profiles were identified that varied in their risk of suspected sepsis and associated outcomes. Validation of these profiles in diverse populations and identification of which profiles are likely to benefit from certain interventions is needed.

Variable selection is a common technique to identify the most predictive variables from a pool of candidate predictors. Low prevalence predictors (LPPs) are frequently found in clinical data, yet few studies have explored their impact on model performance during variable selection. This study compared the Random Forest (RF) algorithm and stepwise regression (SWR) for variable selection using data from a paediatric sepsis screening tool, where 18 out of 32 predictors had a prevalence < 10

OBJECTIVES: In children with septic shock, guidelines recommend resuscitation with 40-60 mL/kg of fluid boluses, yet there is a lack of evidence to support this practice. We aimed to determine the feasibility of a randomized trial comparing early adrenaline infusion with standard fluid resuscitation in children with septic shock. DESIGN: Open-label parallel randomized controlled, multicenter pilot study. The primary end point was feasibility; the exploratory clinical endpoint was survival free of organ dysfunction by 28 days. SETTING: Four pediatric Emergency Departments in Queensland, Australia. PATIENTS: Children between 28 days and 18 years old with septic shock. INTERVENTIONS: Patients were assigned 1:1 to receive a continuous adrenaline infusion after 20 mL/kg fluid bolus resuscitation (n = 17), or standard care fluid resuscitation defined as delivery of 40 to 60 mL/kg fluid bolus resuscitation prior to inotrope commencement (n = 23). MEASUREMENTS AND MAIN RESULTS: Forty of 58 eligible patients (69%) were consented with a median age of 3.7 years (interquartile range [IQR], 0.9-12.1 yr). The median time from randomization to inotropes was 16 minutes (IQR, 12-26 min) in the intervention group, and 49 minutes (IQR, 29-63 min) in the standard care group. The median amount of fluid delivered during the first 24 hours was 0 mL/kg (IQR, 0-10.0 mL/kg) in the intervention group, and 20.0 mL/kg (14.6-28.6 mL/kg) in the standard group (difference, -20.0; 95% CI, -28.0 to -12.0). The number of days alive and free of organ dysfunction did not differ between the intervention and standard care groups, with a median of 27 days (IQR, 26-27 d) versus 26 days (IQR, 25-27 d). There were no adverse events reported associated with the intervention. CONCLUSIONS: In children with septic shock, a protocol comparing early administration of adrenaline versus standard care achieved separation between the study arms in relation to inotrope and fluid bolus use.

OBJECTIVES: Adjunctive therapy with vitamin C, hydrocortisone, and thiamin has been evaluated in adults, but randomized controlled trial (RCT) data in children are lacking. We aimed to test the feasibility of vitamin C, hydrocortisone, and thiamin in PICU patients with septic shock; and to explore whether the intervention is associated with increased survival free of organ dysfunction. DESIGN: Open-label parallel, pilot RCT multicenter study. The primary endpoint was feasibility. Clinical endpoints included survival free of organ dysfunction censored at 28 days and nine secondary outcomes, shock reversal, and two proxy measures of intervention efficacy. SETTING: Six PICUs in Australia and New Zealand. PATIENTS: Children of age between 28 days and 18 years requiring vasoactive drugs for septic shock between August 2019 and March 2021. INTERVENTIONS: Patients were assigned 1:1 to receive 1 mg/kg hydrocortisone every 6 hours (q6h), 30 mg/kg ascorbic acid q6h, and 4 mg/kg thiamin every 12 hours ( n = 27), or standard septic shock management ( n = 33). MEASUREMENTS AND MAIN RESULTS: Sixty of 77 (78%) eligible patients consented with 91% of approached parents providing consent. The median time from randomization to intervention was 44 (interquartile range [IQR] 29–120) min. Seventy of seventy-seven (28%) patients had received IV steroids before randomization. Median survival alive and free of organ dysfunction was 20.0 (0.0–26.0) days in the intervention and 21.0 (0.0–25.0) days in the standard care group. Median PICU length of stay was 5.3 (2.5–11.3) days in the intervention group versus 6.9 (3.0–11.5) days in the control group. Shock reversal occurred at a median of 35.2 (14.6–101.2) hours in the intervention group versus 47.3 (22.4–106.8) hours in the standard care group (median difference –12 hr; 95% CI, –56.8 to 32.7 hr). CONCLUSIONS: In children requiring vasopressors for septic shock, a protocol comparing adjunctive treatment with high-dose vitamin C, hydrocortisone, and thiamin versus standard care was feasible. These findings assist in making modifications to the trial protocol to enable a better-designed larger RCT.

Abstract Background Escherichia coli is the most common cause of human bloodstream infections and bacterial sepsis/septic shock. However, translation of preclinical septic shock resuscitative therapies remains limited mainly due to low-fidelity of available models in mimicking clinical illness. To overcome the translational barrier, we sought to replicate sepsis complexity by creating an acutely critically-ill preclinical bacterial septic shock model undergoing active 48-h intensive care management. Aim To develop a clinically relevant large-animal (ovine) live-bacterial infusion model for septic shock. Methods Septic shock was induced by intravenous infusion of the live antibiotic resistant extra-intestinal pathogenic E. coli sequence type 131 strain EC958 in eight anesthetised and mechanically ventilated sheep. A bacterial dose range of 2 × 105–2 × 109 cfu/mL was used for the dose optimisation phase (n = 4) and upon dose confirmation the model was developed (n = 5). Post-shock the animals underwent an early-vasopressor and volume-restriction resuscitation strategy with active haemodynamic management and monitoring over 48 h. Serial blood samples were collected for testing of pro-inflammatory (IL-6, IL-8, VEGFA) and anti-inflammatory (IL-10) cytokines and hyaluronan assay to assess endothelial integrity. Tissue samples were collected for histopathology and transmission electron microscopy. Results The 2 × 107 cfu/mL bacterial dose led to a reproducible distributive shock within a pre-determined 12-h period. Five sheep were used to demonstrate consistency of the model. Bacterial infusion led to development of septic shock in all animals. The baseline mean arterial blood pressure reduced from a median of 91 mmHg (71, 102) to 50 mmHg (48, 57) (p = 0.004) and lactate levels increased from a median of 0.5 mM (0.3, 0.8) to 2.1 mM (2.0, 2.3) (p = 0.02) post-shock. The baseline median hyaluronan levels increased significantly from 25 ng/mL (18, 86) to 168 ng/mL (86, 569), p = 0.05 but not the median vasopressor dependency index which increased within 1 h of resuscitation from zero to 0.39 mmHg−1 (0.06, 5.13), p = 0.065, and. Over the 48 h, there was a significant decrease in the systemic vascular resistance index (F = 7.46, p = 0.01) and increase in the pro-inflammatory cytokines [IL-6 (F = 8.90, p = 0.02), IL-8 (F = 5.28, p = 0.03), and VEGFA (F = 6.47, p = 0.02)]. Conclusions This critically ill large-animal model was consistent in reproducing septic shock and will be applied in investigating advanced resuscitation and therapeutic interventions.

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.

ObjectiveThe Surviving Sepsis Campaign recommends systematic screening for sepsis. Although many sepsis screening tools include parent or healthcare professional concern, there remains a lack of evidence to support this practice. We aimed to test the diagnostic accuracy of parent and healthcare professional concern in relation to illness severity, to diagnose sepsis in children.DesignThis prospective multicenter study measured the level of concern for illness severity as perceived by the parent, treating nurse and doctor using a cross-sectional survey. The primary outcome was sepsis, defined as a pSOFA score >0. The unadjusted area under receiver-operating characteristic curves (AUC) and adjusted Odds Ratios (aOR) were calculated.SettingTwo specialised pediatric Emergency Departments in QueenslandPatientsChildren aged 30 days to 18 years old that were evaluated for sepsisInterventionNoneMain Results492 children were included in the study, of which 118 (23.9%) had sepsis. Parent concern was not associated with sepsis (AUC 0.53, 95% CI: 0.46–0.61, aOR: 1.18; 0.89–1.58) but was for PICU admission (OR: 1.88, 95% CI: 1.17–3.19) and bacterial infection (aOR: 1.47, 95% CI: 1.14–1.92). Healthcare professional concern was associated with sepsis in both unadjusted and adjusted models (nurses: AUC 0.57, 95% CI-0.50, 0.63, aOR: 1.29, 95% CI: 1.02–1.63; doctors: AUC 0.63, 95% CI: 0.55, 0.70, aOR: 1.61, 95% CI: 1.14–2.19).ConclusionsWhile our study does not support the broad use of parent or healthcare professional concern in isolation as a pediatric sepsis screening tool, measures of concern may be valuable as an adjunct in combination with other clinical data to support sepsis recognition.Clinical Trial RegistrationACTRN12620001340921.

Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection; it affects 55 000 Australians and results in around 8700 deaths annually.1 Studies have shown that junior doctors have reduced awareness of the importance of sepsis as a time-critical illness.2 Whether this deficiency is a consequence of insufficient training on sepsis in medical schools is unknown. This study evaluated the knowledge of sepsis among medical students in two Australian universities

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.

We examined systems-level costs before and after the implementation of an emergency department paediatric sepsis screening, recognition and treatment pathway. Aggregated hospital admissions for all children aged < 18y with a diagnosis code of sepsis upon admission in Queensland, Australia were compared for 16 participating and 32 non-participating hospitals before and after pathway implementation. Monte Carlo simulation was used to generate uncertainty intervals. Policy impacts were estimated using difference-in-difference analysis comparing observed and expected results. We compared 1055 patient episodes before (77.6% in-pathway) and 1504 after (80.5% in-pathway) implementation. Reductions were likely for non-intensive length of stay (− 20.8 h [− 36.1, − 8.0]) but not intensive care (–9.4 h [− 24.4, 5.0]). Non-pathway utilisation was likely unchanged for interhospital transfers (+ 3.2% [− 5.0%, 11.4%]), non-intensive (− 4.5 h [− 19.0, 9.8]) and intensive (+ 7.7 h, [− 20.9, 37.7]) care length of stay. After difference-in-difference adjustment, estimated savings were 596 [277, 942] non-intensive and 172 [148, 222] intensive care days. The program was cost-saving in 63.4% of simulations, with a mean value of $97,019 [− $857,273, $1,654,925] over 24 months. A paediatric sepsis pathway in Queensland emergency departments was associated with potential reductions in hospital utilisation and costs.

OBJECTIVES:. To evaluate the implementation of a pediatric sepsis pathway in the emergency department as part of a statewide quality improvement initiative in Queensland, Australia. DESIGN:. Multicenter observational prospective cohort study. SETTING:. Twelve emergency departments in Queensland, Australia. PATIENTS:. Children less than 18 years evaluated for sepsis in the emergency department. Patients with signs of shock, nonshocked patients with signs of organ dysfunction, and patients without organ dysfunction were assessed. INTERVENTIONS:. Introduction of a pediatric sepsis pathway. MEASUREMENTS AND MAIN RESULTS:. Process measures included compliance with and timeliness of the sepsis bundle, and bundle components. Process and outcome measures of children admitted to the ICU with sepsis were compared with a baseline cohort. Five-hundred twenty-three children were treated for sepsis including 291 with suspected sepsis without organ dysfunction, 86 with sepsis-associated organ dysfunction, and 146 with septic shock. Twenty-four (5%) were admitted to ICU, and three (1%) died. The median time from sepsis recognition to bundle commencement for children with septic shock was 56 minutes (interquartile range, 36–99 min) and 47 minutes (interquartile range, 34–76 min) for children with sepsis-associated organ dysfunction without shock; 30% (n = 44) and 40% (n = 34), respectively, received the bundle within the target timeframe. In comparison with the baseline ICU cohort, bundle compliance improved from 27% (n = 45) to 58% (n = 14) within 60 minutes of recognition and from 47% (n = 78/167) to 75% (n = 18) within 180 minutes of recognition (p < 0.05). CONCLUSIONS:. Our findings on the introduction of protocolized care in a large and diverse state demonstrate ongoing variability in sepsis bundle compliance. Although bundle compliance improved compared with a baseline cohort, continued efforts are required to ensure guideline targets and sustainability are achieved.

Introduction: Septic shock in children still carries substantial mortality and morbidity. While resuscitation with 40–60 mL/kg intravenous fluid boluses remains a cornerstone of initial resuscitation, an increasing body of evidence indicates potential for harm related to high volume fluid administration. We hypothesize that a protocol on early use of inotropes in children with septic shock is feasible and will lead to less fluid bolus use compared to standard fluid resuscitation. Here, we describe the protocol of the Early Resuscitation in Paediatric Sepsis Using Inotropes – A Randomised Controlled Pilot Study in the Emergency Department (RESPOND ED). Methods and analysis: The RESPOND ED study is an open label randomised controlled, two arm, multicentre pilot study conducted at four specialised paediatric Emergency Departments. Forty children aged between 28 days and 18 years treated for presumed septic shock will be randomized in a 1:1 ratio to early inotropes vs. standard fluid resuscitation. Early inotrope treatment is defined as the commencement of a continuous intravenous adrenaline infusion after 20 mL/kg fluid bolus resuscitation. Standard fluid resuscitation is defined as delivery of 40 to 60 mL/kg fluid bolus resuscitation prior to commencement of inotropes. In addition to feasibility outcomes, survival free of organ dysfunction censored at 28 days will be assessed as the main clinical outcome. The study cohort will be followed up at 28 days, and at 6 months post enrolment to assess quality of life and functional status. Biobanking nested in the study cohort will be performed to enable ancillary biomarker studies. Ethics and dissemination: The trial has ethical clearance (Children's Health Queensland, Brisbane, HREC/18/QCHQ/49168) and is registered in the Australian New Zealand Clinical Trials Registry (ACTRN12619000828123). Enrolment commenced on July 21st, 2019. The primary manuscript will be submitted for publication in a peer-reviewed journal.

Paediatric sepsis remains a leading cause of childhood death. Morbidity is high, with up to one third of children affected developing ongoing, sometimes lifelong sequelae. To address the major burden of sepsis on child health, there is need for a unified approach to care, as outlined in the Australian National Action Plan for sepsis. While the Surviving Sepsis Campaign 2020 guidelines provided evidence-based recommendations for sepsis management in hospital, additional emphasis on families, pre-hospital recognition and post-sepsis care incorporating the multidisciplinary team is paramount to achieve quality patient outcomes. The role of families, paramedics and nurses in recognising and managing paediatric sepsis remains an under-represented area in current literature. The aim of this paper is to critically discuss key challenges surrounding the journey of paediatric sepsis, drawing on contemporary literature to highlight key areas pertinent to recognition and management of sepsis in children. Application of a holistic, patient-centred focus will provide an overview of paediatric sepsis, aiming to inform future development for enhanced healthcare delivery and identify critical areas for further research.

Introduction: Paediatric post sepsis syndrome is poorly defined and causes physical, neurocognitive, psychosocial morbidity, and family dysfunction. Families of sepsis survivors report unmet needs during care. Worldwide, the provision of post sepsis care is in its infancy with limited evidence to design clinical support pathways.Perspective: The Queensland Paediatric Sepsis Program (QPSP) developed a family support structure (FSS) to improve care during all stages of childhood sepsis. It was designed in partnership with consumers guided by information from consumers and it is partly delivered by consumers. Key areas include online, multimodal education for families and the ability to connect with other families affected by sepsis. The FSS is delivered by a multidisciplinary team (MDT) acting with clinicians local to the child. Families can join the FSS registry at any stage of their sepsis journey which connects them to our MDT team and opens opportunities to participate in future research and other initiatives. Improving public awareness is a critical outcome for our consumers and they have co-designed media and digital campaigns.Discussion: The ideal FSS for post sepsis syndrome management is a clinical pathway designed in partnership with consumers of interventions proven to improve outcomes from sepsis that meets their requirements. The QPSP FSS is novel as it is co-designed with, and partly delivered by, consumers with interventions aimed to improve the entire spectrum of morbidities suffered by survivors and their families, not just physical sequelae. Evaluation is embedded in the program and outcomes will guide evolution of the FSS.

Background: Sepsis is a leading cause of death and disability in adults and children. Evidence suggests that early recognition and management can significantly improve patient outcomes, therefore education of healthcare workers around sepsis is critical. Little is known about the preparation of final year nursing students regarding recognition and response to sepsis. Objectives: To explore Australian final year nursing student's exposure to and knowledge of sepsis, and their awareness of the importance of early recognition, escalation and management of patients with sepsis. Methods: An online 17-question survey was developed, validated and then used to evaluate final year nursing students' awareness and knowledge about sepsis. Design: Multi-site, cross-sectional, study. Settings: Data were prospectively collected from final year nursing students from five university (graduate entry and undergraduate) programmes from four Universities in Queensland, Australia. Results: Response rate of 22% (237/1075 eligible students responded). Final year nursing students possessed limited knowledge about sepsis (mean scores = 3.8/9; SD = 1.6), and very limited knowledge of paediatric sepsis (median 1[interquartile range 0-1]). Many participants (54%; 128/237) had heard of sepsis prior to commencing their nursing studies, however only 22% (53/237) reported formal dedicated educational units on sepsis. Sepsis education was delivered primarily through didactic lectures (32%; 77/237) and often as part of courses encompassing acute care (38%; 91/237). Only 6% (14/237) of participants recalled exposure to education dedicated to paediatric sepsis. Conclusions: The knowledge of final year nursing students in relation to recognising, escalating and managing sepsis was limited. There is an urgent need to design education which adequately and safely prepares nurses for the challenges they face when caring for patients with sepsis, particularly paediatric sepsis. Accrediting bodies should consider mandating inclusion of sepsis education as part of all nursing programmes.

Introduction Paediatric sepsis is a major contributor to morbidity and mortality worldwide. Assessing concern from parents and healthcare professionals to determine disease severity in a child evaluated for sepsis remains a field requiring further investigation. This study aims to determine the diagnostic accuracy of parental and healthcare professional concern in the diagnosis of children evaluated for sepsis. Methods and analysis This prospective multicentre observational study will be conducted over a 24-month period in the paediatric emergency department (ED) at two tertiary Australian hospitals. A cross-sectional survey design will be used to assess the level of concern in parents, nurses and doctors for children presenting to ED and undergoing assessment for sepsis. The primary outcome is a diagnosis of sepsis, defined as suspected infection plus organ dysfunction at time of survey completion. Secondary outcomes include suspected or proven infection and development of organ dysfunction, defined as a Paediatric Sequential Organ Failure Assessment Score >0, within 48 hours of presentation, paediatric intensive care unit admission, confirmed or probable bacterial infection independent of organ dysfunction, and hospital length of stay. Ethics and dissemination Ethics approval was obtained from Children’s Health Queensland’s Human Research Ethics Committee (HREC/17/QRCH/85). Findings will be shared with relevant stakeholders and disseminated via conferences and peer-reviewed journals Trial registration number WHO Universal Trial Number, U1111-1256-4537; ANZCTR number, ACTRN1262000134092.

Objectives To describe haemodynamic resuscitation practices in ED patients with suspected sepsis and hypotension. Methods This was a prospective, multicentre, observational study conducted in 70 hospitals in Australia and New Zealand between September 2018 and January 2019. Consecutive adults presenting to the ED during a 30-day period at each site, with suspected sepsis and hypotension (systolic blood pressure <100 mmHg) despite at least 1000 mL fluid resuscitation, were eligible. Data included baseline demographics, clinical and laboratory variables and intravenous fluid volume administered, vasopressor administration at baseline and 6- and 24-h post-enrolment, time to antimicrobial administration, intensive care admission, organ support and in-hospital mortality. Results A total of 4477 patients were screened and 591 were included with a mean (standard deviation) age of 62 (19) years, Acute Physiology and Chronic Health Evaluation II score 15.2 (6.6) and a median (interquartile range) systolic blood pressure of 94 mmHg (87-100). Median time to first intravenous antimicrobials was 77 min (42-148). A vasopressor infusion was commenced within 24 h in 177 (30.2%) patients, with noradrenaline the most frequently used (n = 138, 78%). A median of 2000 mL (1500-3000) of intravenous fluids was administered prior to commencing vasopressors. The total volume of fluid administered from pre-enrolment to 24 h was 4200 mL (3000-5661), with a range from 1000 to 12 200 mL. Two hundred and eighteen patients (37.1%) were admitted to an intensive care unit. Overall in-hospital mortality was 6.2% (95% confidence interval 4.4-8.5%). Conclusion Current resuscitation practice in patients with sepsis and hypotension varies widely and occupies the spectrum between a restricted volume/earlier vasopressor and liberal fluid/later vasopressor strategy.
