Background: A wide variation of emergency medical system configurations across countries has limited the value of comparison of quality and performance measures in the past. Furthermore, lack of quantitative data on EDs prevents definition of the problems and possibilities for data driven improvement of quality of care. Therefore, the objective is to describe and compare Emergency Department (ED) populations and characteristics, and their outcomes in the Netherlands, Denmark and Australia, using a recently developed template for uniform reporting of standardized measuring and describing of care provided in the ED (structure, staffing and governance, population, process times and outcomes)., Methods: This international multicenter cohort included all consecutive ED visits from National Quality Registries or Databases from participating sites from three countries. Patient and ED characteristics (using the template for uniform reporting) and relevant clinical outcomes were described and compared per country., Results: We included 212,515 ED visits in the Netherlands, 408,673 in Denmark and 556,652 in Australia. Patient characteristics differed markedly, with Australian ED patients being younger, less often triaged as "immediate", and less often triaged with the high-risk chief complaints "feeling unwell" compared to Danish and Dutch patients. ED characteristics mainly differed with respect to the mean annual census per ED (Netherlands 26,738 (SD 2630), Denmark 36,675 (SD 12974), Australia 50,712 (4884)), median (IQR) lengths of stay of patients discharged home (Netherlands 2.1 (1.4-3.1); Denmark 2.8 (1.7-5.0); Australia 3.3 (2.0-5.0) hrs) and proportion of hospitalizations (ranging from 30.6 to 39.8%). In-hospital mortality was 4.0% in Australia, higher compared to the Netherlands and Denmark (both 1.6%). Not all indicators of the framework were available in all registries., Conclusions: Patient and ED characteristics and outcomes varied largely across countries. Meaningful interpretation of outcome differences across countries could be improved if quality registries would more consistently register the measures of the recently developed template for uniform reporting., (© 2024.

Background: Citizen science and models for public participation in health research share normative ideals of participation, inclusion, and public and patient engagement. Academic researchers collaborate in research with members of the public involved in an issue, maximizing all involved assets, competencies, and knowledge. In citizen science new ethical issues arise, such as who decides, who participates, who is excluded, what it means to share power equally, or whose knowledge counts. This article aims to present an ethics framework that offers a lens of understanding and heuristic guidelines to deal with ethical issues in citizen science., Methods: We conducted seven case studies between 2015 and 2021 to attune and validate the ethics framework for the context of citizen science. The cases related to studies with older adults, people with a psychiatric vulnerability, people dependent on community care, people who are unemployed or living in poverty or both, and young adults with respiratory disease., Results: Ethics in citizen science reaches beyond the ethical issues in traditional biomedical and health research. It entails more than following procedures about informed consent and privacy and submitting a proposal to a Medical Research Ethics Committee. Ethics in citizen science relates to everyday ethical issues during the study, including relational and moral complexities concerning collaboration, sharing power, and democratic decision-making. Dealing with these issues requires ethics work of researchers. This entails seeing ethically salient issues and reflecting on everyday ethical issues. Ethics work consists of seven features: framing work, role work, emotion work, identity work, reason work, relationship work, and performance work. All are relevant for researchers in citizen science., Conclusions: Ethical issues in citizen science often relate to power differentials, partnership, and collaboration between academics and non-academics. The ethics framework prepares researchers for the work needed in citizen science to act responsibly and offers a heuristic guide to reflect on ethics. Reflection on ethics is a pathway towards ethical citizen science, especially if researchers collaboratively reflect in partnership with non-academics who are subject to the moral issue., (© 2022.

Background: The patient perspective on the use of screening for high risks of adverse health outcomes in Emergency Department (ED) care is underexposed, although it is an important perspective influencing implementation in routine care. This study explores the experiences with, and attitudes towards geriatric screening in routine ED care among older people who visited the ED., Methods: This was a qualitative study using individual face-to-face semi-structured interviews. Interviews were conducted in older patients (≥70 years) who completed the 'Acutely Presenting Older Patient' screener while visiting the ED of a Dutch academic hospital. Purposive convenience sampling was used to select a heterogeneous sample of participants regarding age, disease severity and the result from screening. Transcripts were analyzed inductively using thematic analysis., Results: After 13 interviews (7 women, median age 82 years), data saturation was reached. The participants had noticed little of the screening administration during triage and screening was considered as a normal part of ED care. Most participants believed that geriatric screening contributes to assessing older patients holistically, recognizing geriatric problems early and comforting patients with communication and attention. None of the participants had a negative attitude towards screening or thought that screening is discrimination on age. Care providers should communicate respectfully with frail older patients and involve them in decision-making., Conclusions: Older patients experienced geriatric screening as a normal part of ED care and had predominantly positive attitudes towards its use in the ED. This qualitative study advocates for continuing the implementation of geriatric screening in routine ED practice.

Background: Falls in older Emergency Department (ED) patients may indicate underlying frailty. Geriatric follow-up might help improve outcomes in addition to managing the direct cause and consequence of the fall. We aimed to study whether fall characteristics and the result of geriatric screening in the ED are independently related to adverse outcomes in older patients with fall-related ED visits., Methods: This was a secondary analysis of the observational multicenter Acutely Presenting Older Patient (APOP) study, of which a subset of patients aged ≥70 years with fall-related ED visits were prospectively included in EDs of two Dutch hospitals. Fall characteristics (cause and location) were retrospectively collected. The APOP-screener was used as a geriatric screening tool. The outcome was 3- and 12-months functional decline and mortality. We assessed to what extent fall characteristics and the geriatric screening result were independent predictors of the outcome, using multivariable logistic regression analysis., Results: We included 393 patients (median age 80 (IQR 76-86) years) of whom 23.0% were high risk according to screening. The cause of the fall was extrinsic (49.6%), intrinsic (29.3%), unexplained (6.4%) or missing (14.8%). A high risk geriatric screening result was related to increased risk of adverse outcomes (3-months adjusted odds ratio (AOR) 2.27 (1.29-3.98), 12-months AOR 2.20 (1.25-3.89)). Independent of geriatric screening result, an intrinsic cause of the fall increased the risk of 3-months adverse outcomes (AOR 1.92 (1.13-3.26)) and a fall indoors increased the risk of 3-months (AOR 2.14 (1.22-3.74)) and 12-months adverse outcomes (AOR 1.78 (1.03-3.10))., Conclusions: A high risk geriatric screening result and fall characteristics were both independently associated with adverse outcomes in older ED patients, suggesting that information on both should be evaluated to guide follow-up geriatric assessment and interventions in clinical care.

Objective: Recent studies suggest that hypotension thresholds in current guidelines might be too low for older patients due to arterial stiffening, possibly leading to insufficient fluid resuscitation. We compared intravenous (IV) fluid volumes that older (≥ 70 years) and younger (< 70 years) patients with suspected infection with similar initial systolic blood pressure (SBP) received in the emergency department (ED) and investigated whether this was associated with in-hospital mortality in older patients., Methods: This was an observational multicenter study using an existing database in which consecutive ED patients hospitalized with suspected infection were prospectively included. We first compared the fluid volumes older and younger ED patients received per initial SBP category. Patients were then stratified into two SBP categories (≤ or > 120 mmHg; 120 has been suggested to be a better threshold) and thereafter into three fluid volume categories: 0-1 L, 1-2 L, or > 2 L. In each SBP and fluid category, case-mix-adjusted in-hospital mortality was compared between older and younger patients, using multivariable logistic regression analysis., Results: The included 981 (37%) older and 1678 (63%) younger ED patients received similar IV fluid volumes per initial SBP category. Older patients with an initial SBP > 120 mmHg had a higher adjusted OR of 2.06 (95% CI 1.02-4.16), in the 0-1 L category, while this association was not found in the higher fluid categories of 1-2 L or > 2 L. In the SBP ≤ 120 mmHg category, this association was also absent., Conclusion: This hypothesis-generating study suggests that older patients with suspected infection may need higher fluid volumes than younger patients, when having a seemingly normal initial SBP.

Background: Emergency department (ED) overcrowding is a potential threat for patient safety. We searched for independent determinants of prolonged ED length of stay (LOS) with the aim to identify factors which can be targeted to reduce ED LOS, which may help in preventing overcrowding., Methods: This prospective cohort study included consecutive ED patients in a Dutch tertiary care centre. Multivariable logistic regression analysis was used to identify independent determinants of ED LOS > 4 h, including patient characteristics (demographics, referral type, acuity, (number of) presenting complaints and comorbidity), treating specialty, diagnostic testing, consultations, number of patients in the ED and disposition. Furthermore, we quantified the absolute time delays (measured in real-time) associated with the most important independent determinants of prolonged ED LOS., Results: In 1434 included patients independent determinants of prolonged ED LOS were number and type of presenting complaints, specialty, laboratory/radiology testing and consultations, and ICU admission. Modifiable determinants with the largest impact were blood testing; Adjusted odds ratio (AOR (95%-CI)); 3.45 (1.95-6.11), urine testing; 1.79 (1.21-2.63), radiology imaging; 3.02 (2.13-4.30), and consultation; 5.90 (4.08-8.54). Combined with the laboratory/radiology testing and/or consultations (requested in 1123 (78%) patients) the decision-making and discharge process consumed between 74 (42%) and 117 (66%) minutes of the total ED LOS of 177 (IQR: 129-225) minutes., Conclusions: In tertiary care EDs, ED LOS can be reduced if the process of laboratory/radiology testing and consulting is optimized and the decision-making and discharge procedures are accelerated.

Background: Sepsis recognition in older emergency department (ED) patients is difficult due to atypical symptom presentation. We therefore investigated whether the prognostic and discriminative performance of the five most commonly used disease severity scores were appropriate for risk stratification of older ED sepsis patients (≥70 years) compared to a younger control group (<70 years)., Methods: This was an observational multi-centre study using an existing database in which ED patients who were hospitalized with a suspected infection were prospectively included. Patients were stratified by age < 70 and ≥70 years. We assessed the association with in-hospital mortality (primary outcome) and the area under the curve (AUC) with receiver operator characteristics of the Predisposition, Infection, Response, Organ dysfunction (PIRO), quick Sequential Organ Failure Assessment (qSOFA), Mortality in ED Sepsis (MEDS), and the Modified and National Early Warning (MEWS and NEWS) scores., Results: In-hospital mortality was 9.5% ((95%-CI); 7.4-11.5) in the 783 included older patients, and 4.6% (3.6-5.7) in the 1497 included younger patients. In contrast to younger patients, disease severity scores in older patients associated poorly with mortality. The AUCs of all disease severity scores were poor and ranged from 0.56 to 0.64 in older patients, significantly lower than the good AUC range from 0.72 to 0.86 in younger patients. The MEDS had the best AUC (0.64 (0.57-0.71)) in older patients. In older and younger patients, the newly proposed qSOFA score (Sepsis 3.0) had a lower AUC than the PIRO score (sepsis 2.0)., Conclusion: The prognostic and discriminative performance of the five most commonly used disease severity scores was poor and less useful for risk stratification of older ED sepsis patients.

Background: Older people frequently attend the emergency department (ED) and have a high risk of poor outcome as compared to their younger counterparts. Our aim was to study routinely collected clinical parameters as predictors of 90-day mortality in older patients attending our ED., Methods: We conducted a retrospective follow-up study at the Leiden University Medical Center (The Netherlands) among patients aged 70 years or older attending the ED in 2012. Predictors were age, gender, time and way of arrival, presenting complaint, consulting medical specialty, vital signs, pain score and laboratory testing. Cox regression analyses were performed to analyse the association between these predictors and 90-day mortality., Results: Three thousand two hundred one unique patients were eligible for inclusion. Ninety-day mortality was 10.5 % for the total group. Independent predictors of mortality were age (hazard ratio [HR] 1.06, 95 % confidence interval [95 % CI] 1.04-1.08), referral from another hospital (HR 2.74, 95 % CI 1.22-6.11), allocation to a non-surgical specialty (HR: 1.55, 95 % CI 1.13-2.14), increased respiration rate (HR up to 2.21, 95 % CI 1.25-3.92), low oxygen saturation (HR up to 1.96, 95 % CI 1.19-3.23), hypothermia (HR 2.27, 95 % CI 1.28-4.01), fever (HR 0.43, 95 % CI 0.24-0.75), high pain score (HR 1.55, 95 % CI 1.03-2.32) and the indication to perform laboratory testing (HR 3.44, 95 % CI 2.13-5.56)., Conclusions: Routinely collected parameters at the ED can predict 90-day mortality in older patients presenting to the ED. This study forms the first step towards creating a new and simple screening tool to predict and improve health outcome in acutely presenting older patients.

Background: Splenic injury is normally associated with trauma, but spontaneous splenic rupture has been described in various systemic diseases., Case Presentation: A 56-year-old male on oral anticoagulation presented to the emergency department with epigastric pain, nausea, and left upper quadrant tenderness. There was no history of trauma. Contrast-enhanced CT imaging revealed a large subcapsular haematoma of the spleen. Oral anticoagulation was antagonised with vitamin K and the patient was discharged in good condition after 3 days of clinical observation., Conclusion: Non-traumatic splenic rupture is a rare complication of oral anticoagulation.

Background: It is not known whether lack of recognition of organ failure explains the low compliance with the "Surviving Sepsis Campaign" (SSC) guidelines. We evaluated whether compliance was higher in emergency department (ED) sepsis patients with clinically recognizable signs of organ failure compared to patients with only laboratory signs of organ failure., Methods: Three hundred twenty-three ED patients with severe sepsis and septic shock were prospectively included. Multivariable binary logistic regression was used to assess if clinical and biochemical signs of organ failure were associated with compliance to a SSC-based resuscitation bundle. In addition, two-way analysis of variance was used to investigate the relation between the predisposition, infection, response and organ failure (PIRO) score (3 groups: 1-7, 8-14, 15-24) as a measure of illness severity and time to antibiotics with disposition to ward or ICU as effect modifier., Results: One hundred twenty-five of 323 included sepsis patients with new-onset organ failure were admitted to the ICU, and in all these patients the SSC resuscitation bundle was started. Respiratory difficulty, hypotension and altered mental status as clinically recognizable signs of organ failure were independent predictors of 100% compliance and not illness severity per se. Corrected ORs (95% CI) were 3.38 (1.08-10.64), 2.37 (1.07-5.23) and 4.18 (1.92-9.09), respectively. Septic ED patients with clinically evident organ failure were more often admitted to the ICU compared to a ward (125 ICU admissions, P < 0.05), which was associated with shorter time to antibiotics [ward: 127 (113-141) min; ICU 94 (80-108) min (P = 0.005)]., Conclusions: The presence of clinically evident compared to biochemical signs of organ failure was associated with increased compliance with a SSC-based resuscitation bundle and admission to the ICU, suggesting that recognition of severe sepsis is an important barrier for successful implementation of quality improvement programs for septic patients. In septic ED patients admitted to the ICU, the time to antibiotics was shorter compared to patients admitted to a normal ward.
