To examine how socioeconomic deprivation influences referral pathways to emergency departments (EDs) and to assess how these pathways affect subsequent hospital outcomes.

Retrospective observational study.

Emergency department of a large teaching hospital in the East of England, providing secondary and tertiary care.

482 787 ED attendances by patients aged 16 years and over, recorded between January 2019 and December 2023. Patients were assigned Index of Multiple Deprivation (IMD) deciles based on residential postcode.

Referral source (general practitioner (GP), National Health Service (NHS) 111, ambulance, self-referral, other), total ED time, 4-hour breach, hospital admission and unplanned return within 72 hours.

Substantial socioeconomic inequalities were observed in referral pathways. Patients from the most deprived areas were significantly less likely to be referred by a GP (4.7%) than those from the least deprived areas (14.7%) and more likely to arrive via ambulance (32% vs 24%). These differences persisted after adjusting for demographic, clinical and contextual variables. Ambulance referrals showed the longest ED stays, ranging from 347 to 351 min across IMD deciles (overall 95% CI 343 to 363) and the highest probability of 4-hour breaches (51%; 95% CI 50% to 53%). Self-referrals had the greatest rates of unplanned returns within 7 days (up to 7.1%; 95% CI 5.5% to 8.7%). In contrast, NHS 111 and GP referrals were associated with shorter stays, lower breach rates and fewer reattendances. Minimal variation in outcomes was observed across deprivation levels once referral source was accounted for.

Inequalities in how patients access emergency care, particularly reduced GP and NHS 111 referrals among more deprived groups, appear to underpin disparities in ED outcomes. Referral source captures important clinical and system-level factors that influence patient experience and resource use. Interventions to improve equitable access to structured referral pathways, particularly in more deprived areas, may enhance both the efficiency and fairness of emergency care delivery. Further research using national data is needed to assess broader policy implications and economic costs associated with differential access.

To assess the feasibility of conducting a cluster randomised controlled trial comparing the effects of Advanced Trauma Life Support (ATLS) and Primary Trauma Care (PTC) with standard care on patient outcomes.

This was a pilot pragmatic three-armed parallel, cluster randomised, controlled trial conducted between April 2022 and February 2023. Patients were followed up for 30 days.

Tertiary care hospitals across metropolitan areas in India.

Adult trauma patients and residents managing these patients were included.

ATLS or PTC training was provided for residents in the intervention arms.

The outcomes were the consent rate, loss to follow-up rate, missing data rates, differences in the distribution between observed data and data extracted from medical records, and the resident pass rate.

Two hospitals were randomised to the ATLS arm, two to the PTC arm and three to the standard care arm. We included 376 patients and 22 residents. The percentage of patients who consented to follow-up was 77% and the percentage of residents who consented to receive training was 100%. The loss to follow-up rate was 14%. The pass rate was 100%. Overall, the amount of missing data for key variables was low. The data collected through observations were similar to data extracted from medical records, but there were more missing values in the extracted data.

Conducting a full-scale cluster randomised controlled trial comparing the effects of ATLS, PTC and standard care on patient outcomes appears feasible, especially if such a trial would use data and outcomes available in medical records.

NCT05417243.

To conduct a systematic review and narrative synthesis to identify barriers, facilitators and pre-existing interventions and describe the current status of initiatives/interventions aimed at improving access to quality trauma healthcare after injury in Pakistan.

Systematic review and narrative synthesis

MEDLINE (Ovid), Embase (Ovid), Web of Science (Clarivate Analytics), Cochrane (Wiley), Scopus and ProQuest, as well as grey literature.

Full-text peer-reviewed publications, including cross-sectional studies, cohort studies, case-control studies, randomised controlled trials and qualitative studies published in English from January 2013 to December 2023.

Two independent reviewers used a standardised tool to extract data variables to Excel. The quality of the included studies was evaluated using the CASP checklist. The barriers, facilitators and pre-existing interventions were mapped using the four delays framework, the Institute of Medicine (IOM) quality domains and the WHO health systems building blocks. The data were synthesised narratively to improve access to quality trauma care in Pakistan. This review was reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) reporting guidelines.

The review included 20 studies. 19 studies reported 58 barriers to access to quality care. Six studies reported 20 facilitators, and eight studies described initiatives or interventions aimed at improving access to quality trauma healthcare after injury. According to the four delays framework, the receiving care stage of access to care was primarily studied in 16 studies, which identified 37 barriers and 13 facilitators across 5 studies. Regarding the quality of care according to IOM domains, the effectiveness of quality trauma care after an injury was studied in 15 studies, which identified 19 barriers and 10 facilitators across four studies. According to the WHO health system building blocks, most studies (n=15) described challenges in healthcare service delivery, with these 15 studies identifying 23 barriers and 3 studies identifying 4 facilitators.

Our findings highlighted the scarcity of available literature, identified barriers and facilitators and pre-existing interventions, which informed the need to develop feasible, sustainable and contextually relevant interventions to improve access to quality trauma care after injury in Pakistan.

Few studies have quantified the vulnerability of people experiencing homelessness and its association with emergency department (ED) reattendances. The study objectives were to identify the health and social-related vulnerability, comorbidities and reattendance to an ED within 28 days, of people experiencing homelessness and people living in stable housing.

Prospective cohort study, 28 September 2023 to 12 October 2023.

Metropolitan ED in an inner-city public hospital.

Eligible participants were those who attended the ED between 8am and 5pm during the 2 week study period (2023), those aged 18 years and over and able to provide informed consent, and those deemed well enough to participate.

The homeless health access to care tool (HHACT) assesses a person’s unmet needs and quantifies their level of health and social-related vulnerability (low, moderate, high). The HHACT was applied to each participant. Routinely collected administrative data was used to identify participant demographics and ED usage on the day of study enrolment and any ED reattendance within 28 days.

Outcome measures were the identification of participants’ level of health and social-related vulnerability and its relationship to ED reattendance.

Of the 300 ED participants, 38 (12.6%) were experiencing homelessness. There was a greater than twofold increase in odds of 28-day ED reattendance for participants experiencing homelessness (OR=2.93, CI 1.29 to 6.36; p=0.008) or had moderate to high vulnerability scores (participants living in stable housing and participants homeless) (OR=2.67, CI 1.29 to 5.36; p=0.007). Compared with participants in stable housing, prevalence of comorbidities among participants experiencing homelessness was greater regarding mental health challenges (65.8% vs 21.8%); three or more physical health conditions (36.8% vs 13%) and greater alcohol and other drug use (36.8% vs 17.2%).

The high ED reattendance suggests that people experiencing homelessness are not being adequately screened for unmet needs on their first presentation. Comprehensive screening using the HHACT may enhance the identification of the risk of reattendance and provide opportunities to intervene through targeted responses, such as integrated care pathways. While EDs are not designed to address the multifaceted needs of people experiencing homelessness, there is an urgent need to consider how to optimise this population’s access to appropriate care.

Neutropenic fever (NF) has a crude mortality rate of 3–18%. International guidelines recommend that all patients with NF receive ultrabroad-spectrum antibiotics (UBSAs) within 1 hour of emergency department (ED) registration. However, over 70% patients presenting to hospital with suspected NF (sNF) cannot access absolute neutrophil count (ANC) result within 1 hour, do not have NF and do not require UBSAs. In ED and hospitalised patients with sNF, we hypothesise that the ASTERIC protocol effectively and safely reduces the use of UBSAs compared with standard care alone.

This pragmatic, parallel, multicentre, type 1, hybrid effectiveness-implementation, stepped-wedge, before-and-after, cluster randomised controlled trial aims to evaluate whether antibiotic prescribing can be safely reduced through implementing a multifaceted antibiotic stewardship intervention (ASTERIC) in adult patients with sNF presenting to EDs. The sNF was defined as a fever with a single oral temperature of ≥38.3°C (101°F) within 24 hours before ED registration or a temperature of ≥38.0°C (100.4°F) sustained over a 1-hour period, following last chemotherapy or targeted therapy within 6 weeks for any solid tumour, or in any period following therapies against leucaemia, lymphoma, myelodysplastic syndrome, aplastic anaemia, multiple myeloma or recipient of HSCT. The study will involve eight hospitals in Hong Kong with variable baseline practice. We will include 704 adult patients (352 patients in pre-implementation and post-implementation periods, respectively) with sNF (tympanic temperature ≥38.3°C) and 48 staff participants (6 staff participants in each hospital). Healthcare professionals will receive a multifaceted stewardship intervention consisting of risk assessment tools, fast-track ANCs, a decision tool for patient management and antibiotic use, supported by an educational package and staff interaction programmes (ASTERIC protocol). Patients’ blood ANC, and cancer therapy and chronic illness therapy scores will be measured. The RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) and Proctor conceptual frameworks will be followed for evaluation of implementation. The main outcome measures are the mean total dose of UBSAs prescribed in 7 days and serious adverse events at 30 days. Data analysis will incorporate intention-to-treat, per-protocol and as-treated analyses for service outcomes (effectiveness, safety, quality of life assessments and cost-effectiveness) and mixed methods for implementation outcomes, informed by the Theoretical Domains Framework. We expect that the study results will inform health policy with improvement in hospital services in treating stable sNF, evidenced by improved safe antibiotic stewardship, early antibiotic de-escalation and reduced costs and length of stay.

The institutional review boards of all study sites approved this study. This study will establish the ASTERIC protocol safely improves antibiotic stewardship and clinical management in adult patients with sNF. We will disseminate the findings through peer-reviewed publications, conference presentations and educational activities. All patients with sNF will be influenced by the new protocol which is agreed at hospital level. Randomisation is at hospital level, not patient level. Patient consent is sought for follow-up and data access, not for treatment. Staff consent is sought for interviewing.

NCT06794320.

Post-traumatic neck pain is common, representing a substantial human and societal burden. About 15%–25% of individuals involved in an accident causing whiplash continue to experience moderate-to-severe symptoms and functional impairment 1 year post-trauma. Factors such as age, high pain intensity, hypersensitivity to pain and early post-traumatic hyperarousal are associated with persistent neck pain. However, multiple questions remain unanswered regarding how best to improve early care. As such, research on recovery patterns (including indicators for health economic burden) and their predictors is still needed, including biomarkers for pre-traumatic and peri-traumatic stress, and the value of early prediction tools.

This prospective cohort study will include 100 participants (≥18 years) suffering from post-traumatic neck pain sustained within 72 hours of an accident. At baseline (a combination of inclusion and 1 week assessment), eligible participants will undergo a thorough evaluation, including assessment of descriptive characteristics, self-reported variables (eg, pain, disability, sleep quality and post-traumatic stress), biomarkers (eg, heart rate variability (HRV) and hair cortisol) and clinical tests (eg, cervical range of motion). Follow-up will be conducted at 3, 6 and 12 months post-trauma. Further, register data (eg, data on labour market attachment) will be added for the period. Among other methods, a receiver operating characteristic (ROC) curve and multivariable regression analyses will be used to evaluate performance and associations of the prediction tools and their associations with measures of HRV.

The sample size calculation is based on previous studies, estimating that 15% of participants will develop moderate-to-severe ongoing symptoms. Using a conservative estimate, 64 participants are needed to achieve a statistical power of 90% with an expected area under the curve of 0.80. Accounting for a 25% loss to follow-up, 80 participants are required. For regression analysis, 100 participants will be included. The prediction tool will be validated using ROC analysis, sensitivity and specificity. Logistic regression models will be performed with and without biomarkers and pain sensitivity. Health economic costs will be compared across groups. Multivariable regression will examine the link between HRV and post-traumatic stress disorder, adjusting for confounders and a moderation analysis will assess hair cortisol as a potential moderator.

The study is approved by the Regional Committee on Health Research Ethics of Southern Denmark (S-20230037). Due to the acute nature of recruitment, the study design does not allow for a 24-hour reflection period; however, this approach has been approved by the Committee.

Study results will be published in peer-reviewed journals and disseminated through non-scientific outlets, including patient and professional publications, press releases and social media. If effective, workshops for clinicians will be organised. Results will be published regardless of outcome, with coauthorships following ICMJE guidelines.

The aim of this study was to explore the experiences of emergency medical communication centre (EMCC) operators and helicopter emergency medical service (HEMS) physicians following the introduction of an on-site HEMS physician in a Norwegian EMCC.

The study was designed as a qualitative focus group study. Data from the focus groups were analysed using qualitative thematic analysis.

The intervention was implemented at the regional EMCC and one HEMS base in mid-Norway.

Seven HEMS physicians and 22 EMCC operators from the EMCC and HEMS base in Trondheim, Norway, participated in the focus groups.

From 1 February to 5 July 2024, an on-site EMCC physician was introduced in Trondheim EMCC, being responsible for medical decision-making in HEMS dispatches during working hours in the intervention period.

The analysis revealed two overarching themes: (1) perceived impact on the decision-making process in HEMS dispatch and (2) increased trust through mutual learning and closer relationships. Overall, the study participants reported positive experiences with the intervention. They experienced that an on-site physician improved the basis for decision-making in HEMS dispatch, allowing for quicker decisions. The participants were uncertain regarding whether this led to more accurate HEMS dispatch decisions. They valued the opportunity to better understand each other’s skills and build stronger professional relationships.

Both EMCC operators and HEMS physicians experienced improved decision-making and faster dispatch conclusions in HEMS dispatch following the intervention. The high level of medical education and guideline adherence among EMCC operators questions the impact on HEMS dispatch accuracy following the intervention.

Concussion is an acute injury that may contribute to short-term limitations and potential long-term risks.

To test whether a past concussion is associated with the risk of a subsequent serious motor vehicle crash.

Population-based longitudinal cohort analysis.

Ontario, Canada, from 1 April 2002 to 31 March 2022 (178 emergency departments).

Adults diagnosed with a concussion (cases) or an acute ankle sprain (controls), excluding individuals with a disqualifying illness (blindness, dementia, delirium), severe cases resulting in hospitalisation or those who died within 90 days.

Subsequent motor vehicle crash requiring emergency medical care.

We identified 3 037 028 patients, including 425 158 with a concussion and 2 611 870 with an ankle sprain. A total of 200 603 patients were injured in a subsequent motor vehicle crash over a median follow-up of 10 years, equal to an absolute risk of 1 in 15 patients (6.64 per 1000 patient-years). Patients with a concussion had a 49% higher motor vehicle crash risk compared with those with ankle sprain (adjusted relative risk=1.49, 95% CI 1.47 to 1.50, p

This study suggests a significant increased risk of a motor vehicle crash after a concussion that may justify a safety warning from clinicians.

Cellulitis is a common bacterial skin infection causing significant pain, swelling and impact on daily activities, frequently leading to emergency department presentations and hospital admissions. While antibiotics are the mainstay of treatment, they do not directly address inflammation, often resulting in persisting or worsening symptoms in the initial days. Corticosteroids, with their potent anti-inflammatory effects, have shown benefit in other acute infections but are not currently standard care for patients with cellulitis. This trial aims to determine if adjunctive oral dexamethasone can reduce pain and improve outcomes in adults with cellulitis presenting to UK urgent secondary care settings.

This is a pragmatic, multicentre, double-blind, placebo-controlled, randomised, parallel group, phase 3 superiority trial, with an internal pilot and parallel health economic evaluation. Adult patients (≥16 years) with a clinical diagnosis of cellulitis (at any body site except the orbit) presenting to urgent secondary care will be screened for eligibility. 450 participants will be randomised (1:1) to receive either two 8 mg doses of oral dexamethasone or matched placebo, administered approximately 24 hours apart, in addition to standard antibiotic therapy. The primary outcome is total pain experienced over the first 3 days postrandomisation, calculated using the standardised area under the curve from pain scores (Numerical Rating Scale 0–10) across up to seven timepoints. Secondary outcomes include health-related quality of life (EuroQol 5 Dimension 5 Level), patient global impression of improvement, analgesia and antibiotic usage, hospital (re)admissions, complications, unscheduled healthcare use, cellulitis recurrence and cost-effectiveness at 90 days. The primary estimand will apply a treatment policy approach to intercurrent events.

The trial has received ethical approval from South Central—Oxford B Research Ethics Committee (reference: 24/SC/0289) and will be conducted in compliance with Good Clinical Practice and applicable regulations. Informed consent will be obtained from all participants. A model consent form can be seen in . Findings will be disseminated through peer-reviewed publications and conference presentations, and to patient groups and relevant clinical guideline committees.

Prehospital emergency care (PEC) requires rapid evidence-based decisions to maximise the effectiveness of care and to improve clinical outcomes. There are multiple challenges related to clinical research performed in the PEC setting. The aim of our study is to systematically review and assess the characteristics, quality of reporting, risk of bias and pragmatism in recent PEC trials, thereby identifying potential gaps and strengths that can guide the design of future prehospital studies.

We will systematically search databases MEDLINE, Embase and Cochrane CENTRAL to identify all randomised controlled trials conducted in the field of PEC and published in English language between 2010 and 2024. No restrictions will be made to the participants, interventions and outcomes. Risk of bias will be evaluated using the Cochrane Risk of Bias 2 tool. The level of pragmatism will be assessed using the Pragmatic-Explanatory Continuum Indicator Summary-2 score. Exploratory data analysis will be used to investigate and summarise main patterns. Differences in characteristics between PEC fields, study designs, publication year and associations between pragmatism levels, risk of bias and quality of reporting will be the primary focus.

There are no ethical concerns directly relevant to this review. This study has been previously registered with the Open Science Framework (osf.io/rzn9j). The manuscript will be submitted for publication to a relevant, peer-reviewed journal.

During the first wave of the COVID-19 pandemic, there was a notable decline in emergency department (ED) usage in many jurisdictions. This study assessed changes in ED use during this period and explored how the pandemic may have aggravated existing healthcare access inequities.

Our primary objective was to assess pandemic-related changes to ED visits and emergency hospitalisations for distinct demographic groups.

We conducted a retrospective observational study using population-based provincial administrative data.

We analysed data from all the 109 EDs and urgent care centres in Alberta, Canada, during the first wave of the COVID-19 pandemic (15 March 2020 to 30 June 2020), and during the corresponding (control) period 1 year earlier. We conducted subgroup analyses by age, First Nations status, sex, location and material deprivation. We repeated all analyses for pre-selected life-threatening emergency diagnoses.

We examined outcomes for a priori subgroups, including female and ‘other’ sex patients, paediatric patients (age 0–17 years), seniors (age 65 years and older), patients living in remote areas (greater than 200 km from an urban centre), First Nations members and patients living in materially deprived postal codes falling into the two most deprived Pampalon Index quintiles.

Primary outcomes were number of ED visits, number of ED visits with admission to hospital and number of ED visits resulting in patient death in the ED. A secondary outcome was change in ED use for life-threatening diagnoses (eg, cardiac conditions and hepatic disease).

ED visits in the COVID-19 period decreased by 34% (Poisson means test p

Reductions in critical emergency care and emergency hospital admissions were unequally distributed across demographic groups during the COVID-19 period. Study methods could be used to monitor and support equitable access to emergency care among distinct populations.

Pain is a common complaint in patients presenting to an Emergency Department (ED). Data show that timely delivery of pain relief in this setting remains a challenge. Adequate treatment of pain requires recognition and assessment. The Royal College of Emergency Medicine advocates for early pain assessment and reassessment post-analgesia; however, it does not specify how best to do this. Therefore, a review of existing literature is needed to identify which pain assessment tools have been shown to be useful in the ED.

This scoping review will use the Joanna Briggs Institute methodology. A search of PubMed, Embase, Cumulated Index in Nursing and Allied Health Literature, Web of Science, Scopus and the Cochrane Library will identify relevant studies published in English since January 2004. Studies will be included that recruit adults (aged 18 years and over) presenting to an ED with acute pain (duration under 3 months). Publications must assess or compare tools for measuring pain in an ED setting. Full-text articles published internationally will be considered. After duplicate removal, abstract screening and full-text analysis by two independent reviewers will identify relevant papers, using the inclusion criteria. Discrepancy resolution will be via a third reviewer. Pain measurement tools and their evidence will be extracted, collated and described. The findings will be reported according to Preferred Reporting Items for Systematic reviews and Meta-Analyses for Scoping Reviews.

Ethical approval is not required for this review. Published results will be shared with relevant parties interested in ED pain management. Potential next steps include patient involvement in the evaluation of pain assessment tools identified in this review and implementation into practice. The insights of patients with relevant lived experience in assessing these tools would be invaluable to the objective of improving pain management in the emergency setting.

Rapid identification of high-risk and low-risk patients presenting to the emergency department (ED) influences clinical management and can help optimise patient outcomes as well as resource allocation. This study aims to externally validate the Risk Stratification in the Emergency Department in Acutely Ill Older Patients (RISE UP) score in adult patients in the ED with suspected infection. Furthermore, generalisability was assessed by comparing the discriminatory ability of the RISE UP with the quick Sequential Organ Failure Assessment (qSOFA) as well as the Modified Early Warning Score (MEWS) and National Early Warning Score (NEWS).

Retrospective cohort study.

Single-centre study in the ED of a tertiary, university-affiliated hospital.

Adult patients with suspected infection presenting at the ED for internal medicine from 2016 to 2022.

The primary outcome was all-cause 30-day mortality. Secondary outcomes were all-cause 14-day mortality, 7-day mortality and intensive care unit (ICU) admission.

Prognostic performance was evaluated using discrimination (area under the receiver operating characteristic curve (AUC)) and a calibration plot.

Of the included 5038 ED visits, there was a 30-day mortality of 7.1%. Discrimination of RISE UP for 30-day mortality was good (AUC 0.809; 95% CI 0.786 to 0.832) and significantly higher than that for the other risk scores: qSOFA (AUC 0.675; 95% CI 0.644 to 0.707), MEWS (AUC 0.688; 95% CI 0.658 to 0.718) and NEWS (AUC 0.725; 95% CI 0.696 to 0.754) (p

The RISE UP score outperformed the qSOFA, MEWS and NEWS in predicting 30-day mortality. It is generalisable to an adult infection-specific cohort and may facilitate distinction between high-risk and low-risk patients in the ED, particularly to rule out poor outcomes.

The rapidly growing population of older adults (individuals aged 65 years and older) presents a new set of challenges for healthcare providers in the emergency department (ED), given the prevalence of severe and life-threatening conditions among this group, such as chronic cancer, Alzheimer’s disease/dementia and congestive heart failure. ED encounters often represent a critical point in an older patient’s trajectory of care and can thus be an important opportunity for various interventions such as palliative care consultation. Therefore, identifying those who will benefit most from palliative care is of high importance, especially in determining the course of future treatment. Thus, we aim to conduct a systematic review assessing the efficacy of palliative care screening in the ED by assessing inpatient length of stay as the primary outcome and quality of life, percentage of hospitalisation and cost of care as secondary outcomes.

This study will use Ovid MEDLINE, Embase, EBSCO CINAHL, Web of Science and Cochrane as databases. The study population comprises adults aged 60 years and older, with no focus on any specific clinical specialty or disease. Patients who have not received palliative care screening will serve as the comparator. Only studies with an applicable comparator will be considered. Studies published from 1 January 2000 to 1 July 2025 will be included.

All articles will be reviewed independently and in duplicate, and every author will participate in the review, data abstraction and conflict resolution process.

Ethical approval is not required as it is a protocol for a systematic review. Findings will be disseminated through peer-reviewed publications and conference presentations.

Patients with acute psychiatric symptoms are often referred to the emergency department (ED) for medical evaluation to exclude medical causes before psychiatric admission. The absence of a prospectively validated medical screening tool leads to wide practice variation. This study aims to develop a new, evidence-based and consensus-based medical screening tool through a collaborative, interdisciplinary, international Delphi approach.

This modified Delphi study will include representatives from emergency medicine and psychiatry societies across four continents, as well as patient representatives with prior experience of medical screening in the ED. A minimum sample size of 24 participants is planned to account for potential dropouts. The Delphi procedure consists of four rounds. Round 1 will present current evidence and identify key items for the new medical screening tool. Round 2 will evaluate and refine statements from Round 1. Round 3 will seek consensus on the variables to be included in a medical screening tool. In Round 4, hypothetical clinical vignettes will be used to assess the agreement on the recommendations of the newly developed medical screening tool in order to test for content and construct validity. Surveys will be conducted via Research Electronic Data Capture (REDCap), with participants rating statements on a 6-point Likert scale. Response stability will be evaluated using the intraclass correlation coefficient, and consensus defined as ≥80% agreement. Results will be reported according to the ACcurate COnsensus Reporting Document guidelines and the Guidance for Reporting Involvement of Patients and the Public 2 short form.

The Ethics Committee of Northwestern and Central Switzerland exempted the project from committee approval under the Human Research Act on 11 September 2024. Written consent will be obtained from all participants. Results of this study will be summarised as a medical screening tool which will be validated in a prospective, multicentre study in a second step.

Safety culture is essential to improving healthcare quality. Paediatric emergency departments are high-risk environments where evaluating safety culture helps identify areas for improvement. This study aimed to analyse the safety culture among professionals in paediatric emergency departments, according to job category and gender.

Multicentre cross-sectional study using the Hospital Survey on Patient Safety Culture (HSOPSC).

19 paediatric emergency departments, covering all levels of care.

1843 healthcare professionals were invited to participate; the response rate was 63.8%, and 33% of respondents were nurses. All clinical staff in paediatric emergency departments were eligible. Professionals from other specialties and non-clinical staff were excluded.

The primary outcome was the assessment of patient safety culture using the HSOPSC, following the methodology of the Agency for Healthcare Research and Quality. Secondary outcomes included comparisons by job category and gender, and an exploratory cluster analysis.

In terms of patient safety, the main strength was ‘teamwork within units’ (83.65% positive), while the main weakness was ‘staffing’ (61.92% negative). Patient safety was rated with an average score of 7.21 by the participants. Paediatricians rated ‘manager expectations’ significantly higher than nurses (p=0.023) and residents (p=0.026). Paediatricians gave more positive responses overall, with significant differences in ‘communication openness’, ‘feedback and communication’, ‘non-punitive response’ and ‘teamwork across units’, though none were classified as strengths. Cluster analysis showed that the group with more paediatricians identified more strengths and no weaknesses, while the group with more nurses and nursing assistants showed no strengths and significant weaknesses in ‘overall safety perception’, ‘staffing’ and ‘management support’.

Safety culture in paediatric emergency departments is acceptable, but still far from excellent, indicating ample room for improvement. Differences between professional categories, especially between paediatricians and nurses, highlight the need for targeted safety strategies and leadership involvement.

Out-of-hospital cardiac arrest (OHCA) has low survival rates with worse outcomes at night due to delayed emergency medical services (EMS) response, resource limitations and workforce fatigue. Since randomised trials are unfeasible, all-comers registries provide essential data to bridge evidence gaps and improve EMS protocols.

Retrospective observational study using propensity score matching.

National EMS registry and death registry data from Poland, cases from September to November 2022.

Of 2388 eligible patients, cases were grouped by time of cardiac arrest (on-hours: 7:00–18:59; off-hours: 7:00–18:59 AM) and matched 1:1 using propensity scores, yielding 1194 pairs.

Primary: return of spontaneous circulation (ROSC) and 30-day survival.

Secondary: EMS response time.

Our findings revealed significant disparities in OHCA outcomes between day and night shifts. ROSC rates were notably lower at night (20.9% vs 34.8%; p=0.01); however, no difference in 30-day survival was observed (8.3% vs 8.1%; p=0.94). Furthermore, EMS response times were significantly longer during nighttime hours (median and IQR): 12.4 (7.4–14.6) versus 11.2 (6.2–13.5) (minutes); p=0.01.

Patients with OHCA during off-hours experienced longer EMS response times and significantly lower rates of ROSC as compared with daytime hours. No difference in 30-day survival was observed between groups. Potential contributors include reduced staffing, fatigue and logistical delays. System-level changes in EMS scheduling and workforce planning might help to reduce time-of-day-related disparities in OHCA outcomes.

Effective haemorrhage control is crucial in cases of limb trauma involving arterial injury, such as shark attacks, to prevent potentially fatal outcomes. International first aid consensus recommends the use of arterial tourniquets (proprietary or makeshift) as a primary treatment for life-threatening external bleeding. Manual pressure applied directly over a major artery proximal to the injury, such as inguinal fist compression (IFC), is more accessible in a first-aid situation, but is currently not recommended due to limited evidence. The purpose of this study is to determine whether the application of IFC is superior to commercial windlass tourniquets (CWTs) in reducing blood flow in the femoral artery when performed by untrained bystanders.

Stopping Haemorrhage by Application of Randomised Compression or Tourniquet (SHARC-2) is a superiority, assessor-blinded, cross-over, randomised controlled trial conducted with healthy untrained adult volunteers in non-clinical settings. Participants will be rotated as providers and recipients of both IFC and CWT, with providers randomised to the order that they perform the techniques. Providers will be exposed to an educational infographic before applying that technique to a recipient behind a drop sheet. A sonographer, blinded to the technique, will measure the peak systolic velocity of blood flow in the superficial femoral artery using Doppler ultrasound at baseline and then during application of each technique for 5 min. The mean percentage reduction in peak systolic velocity will be compared between IFC and CWT groups.

Ethics approval for this study was granted by the Bond University Human Research Ethics Committee (BUHREC JF01036) on 23 January 2023. All participants will be provided with written informed consent prior to enrolment and the trial will involve healthy adult volunteers. To minimise risk, preintervention screening, sonographic assessment and postintervention follow-up will be implemented with adverse events monitored and reported in accordance with HREC guidelines. Results will be disseminated through peer-reviewed journals, academic conferences, local resuscitation forums and public health education initiatives. A lay summary will also be shared with relevant community groups and via social media platforms to enhance public accessibility.

To describe the features and rates of emergency department (ED) presentations identified as related to violence against women (VAW) and of confirmed cases of family domestic violence (FDV) inpatient admissions and to compare these across geographic locations in New South Wales (NSW) Australia.

A retrospective data linkage study.

Routinely collected public hospital data from approximately 180 designated public hospital EDs in NSW, Australia.

Cases were included if female, aged ≥15 years, presenting to any NSW ED between 2015 and 2022 and with one or more criteria indicating VAW, leading to 21 219 cases being included.

The age-standardised rate of VAW ED presentations per year and confirmed FDV inpatient admissions within metropolitan and non-metropolitan areas in NSW, Australia.

Women presenting with VAW were more likely to be aged 25–44 years (n=9705, 45.7%), with almost 20% of presentations from women who identified as Indigenous (n=4153, 19.6%). Indigenous presentations were greater in non-metropolitan areas (n=2675, 30.9%) compared with metropolitan areas (n=1478, 11.8%). Indigenous women in NSW represent only 4.2% of the estimated residential population. VAW presentation rates by age group varied over time, a gradual increase being seen in the 65–84 year-old age group who experienced 45 VAW presentations per year in 2015 to 79 presentations per year in 2022 with an annual rate of change of 7.3%.

VAW accounts for a substantial burden of ED presentations across NSW; the greatest impact on women aged 25–44 years and Indigenous women, particularly in non-metropolitan areas. Rising presentations among older women further highlight the need for strengthened ED screening and referral pathways and for targeted resource allocation to address inequities in family, domestic and sexual violence.

Improving outcomes from sepsis in children is a WHO Global Health Priority, yet mortality from sepsis remains high, particularly in low- and middle-income countries (LMICs). This database from children with community-acquired childhood sepsis in LMICs and some high-income countries will allow analysis of the burden of disease, including incidence, severity and outcomes. Understanding these aspects of sepsis care is fundamental for the design and conduct of future international interventional trials to improve childhood sepsis outcomes.

This multicountry retrospective observational study will include children up to 18 years of age presenting to emergency departments with suspected sepsis, defined as admission to hospital for treatment with intravenous antibiotics plus (1) a provisional diagnosis of sepsis and/or (2) treatment for suspected sepsis (operationalised as the administration of one or more fluid bolus to treat impaired perfusion or vasoactive infusion). Presenting characteristics, management and outcomes will be collected. These will include vital signs, serum biomarkers, intravenous fluid administration for the first 24 hours of hospitalisation, organ support therapies delivered, antimicrobial use, microbiological diagnoses, hospital and intensive care unit length of stay, and mortality censored at hospital discharge or 30 days from enrolment (whichever occurs first).

Central ethics approval was received from the Royal Children’s Hospital of Melbourne, Australia Human Research Ethics Committee (HREC/100648/RCHM-2023). Each international site will be required to obtain local Institutional Research Ethics Board approval. The findings will be disseminated in peer-reviewed journals, at academic conferences and through lay media. A cleaned study database and individual site-level data will be made available to site investigators upon completion of the study.

This study was registered with the Australian and New Zealand Clinical Trials Registry on 23 January 2024 prior to commencement of recruitment (ACTRN12624000052538).
