RESUMEN
INTRODUCTION: The COVID-19 outbreak disrupted regular health care, including the Emergency Department (ED), and resulted in insufficient ICU capacity. Lockdown measures were taken to prevent disease spread and hospital overcrowding. Little is known about the relationship of stringency of lockdown measures on ED utilization. OBJECTIVE: This study aimed to compare the frequency and characteristics of ED visits during the COVID-19 outbreak in 2020 to 2019, and their relation to stringency of lockdown measures. MATERIAL AND METHODS: A retrospective multicentre study among five Dutch hospitals was performed. The primary outcome was the absolute number of ED visits (year 2018 and 2019 compared to 2020). Secondary outcomes were age, sex, triage category, way of transportation, referral, disposition, and treating medical specialty. The relation between stringency of lockdown measures, measured with the Oxford Stringency Index (OSI) and number and characteristics of ED visits was analysed. RESULTS: The total number of ED visits in the five hospitals in 2019 was 165,894, whereas the total number of visits in 2020 was 135,762, which was a decrease of 18.2% (range per hospital: 10.5%-30.7%). The reduction in ED visits was greater during periods of high stringency lockdown measures, as indicated by OSI. CONCLUSION: The number of ED visits in the Netherlands has significantly dropped during the first year of the COVID-19 pandemic, with a clear association between decreasing ED visits and increasing lockdown measures. The OSI could be used as an indicator in the management of ED visits during a future pandemic.

BACKGROUND: Guidelines and textbooks assert that tachycardia is an early and reliable sign of hypotension, and an increased heart rate (HR) is believed to be an early warning sign for the development of shock, although this response may change by aging, pain, and stress. OBJECTIVE: To assess the unadjusted and adjusted associations between systolic blood pressure (SBP) and HR in emergency department (ED) patients of different age categories (18-50 years; 50-80 years; > 80 years). METHODS: A multicenter cohort study using the Netherlands Emergency department Evaluation Database (NEED) including all ED patients ≥ 18 years from three hospitals in whom HR and SBP were registered at arrival to the ED. Findings were validated in a Danish cohort including ED patients. In addition, a separate cohort was used including ED patients with a suspected infection who were hospitalized from whom measurement of SBP and HR were available prior to, during, and after ED treatment. Associations between SBP and HR were visualized and quantified with scatterplots and regression coefficients (95% confidence interval [CI]). RESULTS: A total of 81,750 ED patients were included from the NEED, and a total of 2358 patients with a suspected infection. No associations were found between SBP and HR in any age category (18-50 years: -0.03 beats/min/10 mm Hg, 95% CI -0.13-0.07, 51-80 years: -0.43 beats/min/10 mm Hg, 95% CI -0.38 to -0.50, > 80 years: -0.61 beats/min/10 mm Hg, 95% CI -0.53 to -0.71), nor in different subgroups of ED patient. No increase in HR existed with a decreasing SBP during ED treatment in ED patients with a suspected infection. CONCLUSION: No association between SBP and HR existed in ED patients of any age category, nor in ED patients who were hospitalized with a suspected infection, even during and after ED treatment. Emergency physicians may be misled by traditional concepts about HR disturbances because tachycardia may be absent in hypotension.

Structural insights in the use of protocols and the extent of practice variation in EDs are lacking. The objective is to determine the extent of practice variation in EDs in The Netherlands, based on specified common practices. We performed a comparative study on Dutch EDs that employed emergency physicians to determine practice variation. Data on practices were collected via a questionnaire. Fifty-two EDs across The Netherlands were included. Thrombosis prophylaxis was prescribed for below-knee plaster immobilization in 27% of EDs. Vitamin C was prescribed in 50% of EDs after a wrist fracture. Splitting of applied casts to the upper or lower limb was performed in one-third of the EDs. Analysis of the cervical spine after trauma was performed by the NEXUS criteria (69%), the Canadian C-spine Rule (17%) or otherwise. The imaging modality for cervical spine trauma in adults was a CT scan (98%). The cast used for scaphoid fractures was divided between the short arm cast (46%) and the navicular cast (54%). Locoregional anaesthesia for femoral fractures was applied in 54% of the EDs. EDs in The Netherlands showed considerable practice variation in treatments among the subjects studied. Further research is warranted to gain a full understanding of the variation in practice in EDs and the potential to improve quality and efficiency.
RESUMEN
OBJECTIVES: Early Warning Scores (EWSs) have a great potential to assist clinical decision-making in the emergency department (ED). However, many EWS contain methodological weaknesses in development and validation and have poor predictive performance in older patients. The aim of this study was to develop and externally validate an International Early Warning Score (IEWS) based on a recalibrated National Early warning Score (NEWS) model including age and sex and evaluate its performance independently at arrival to the ED in three age categories (18-65, 66-80, > 80 yr). DESIGN: International multicenter cohort study. SETTING: Data was used from three Dutch EDs. External validation was performed in two EDs in Denmark. PATIENTS: All consecutive ED patients greater than or equal to 18 years in the Netherlands Emergency department Evaluation Database (NEED) with at least two registered vital signs were included, resulting in 95,553 patients. For external validation, 14,809 patients were included from a Danish Multicenter Cohort (DMC). MEASUREMENTS AND MAIN RESULTS: Model performance to predict in-hospital mortality was evaluated by discrimination, calibration curves and summary statistics, reclassification, and clinical usefulness by decision curve analysis. In-hospital mortality rate was 2.4% ( n = 2,314) in the NEED and 2.5% ( n = 365) in the DMC. Overall, the IEWS performed significantly better than NEWS with an area under the receiving operating characteristic of 0.89 (95% CIs, 0.89-0.90) versus 0.82 (0.82-0.83) in the NEED and 0.87 (0.85-0.88) versus 0.82 (0.80-0.84) at external validation. Calibration for NEWS predictions underestimated risk in older patients and overestimated risk in the youngest, while calibration improved for IEWS with a substantial reclassification of patients from low to high risk and a standardized net benefit of 5-15% in the relevant risk range for all age categories. CONCLUSIONS: The IEWS substantially improves in-hospital mortality prediction for all ED patients greater than or equal to18 years.

Health systems invest in coordination and collaboration between emergency departments (ED) and after-hours primary care providers (AHPCs) to alleviate pressure on the acute care chain. There are substantial gaps in the existing evidence, limited in sample size, follow-up care, and costs. We assess whether acute care collaborations (ACCs) are associated with decreased ED utilization, hospital admission rates, and lower costs per patient journey, compared with stand-alone facilities. The design is a quasi-experimental study using claims data. The study included 610 845 patients in the Netherlands (2017). Patient visits in ACCs were compared to stand-alone EDs and AHPCs. The number of comorbidities was similar in both groups. Multiple logistic and gamma regressions were used to determine whether patient visits to ACCs were negatively associated with ED utilization, hospital admission rates, and costs. Logistic regression analysis did not find an association between patients visiting ACCs and ED utilization compared to patients visiting stand-alone facilities [odds ratio (OR), 1.01; 95% confidence interval (CI), 1.00-1.03]. However, patients in ACCs were associated with an increase in hospital admissions (OR, 1.07; 95% CI, 1.04-1.09). ACCs were associated with higher total costs incurred during the patient journey (OR, 1.02; 95% CI, 1.01-1.03). Collaboration between EDs and AHPCs was not associated with ED utilization, but was associated with increased hospital admission rates, and higher costs. These collaborations do not seem to improve health systems' financial sustainability.

OBJECTIVE: To update the existing CHIP (CT in Head Injury Patients) decision rule for detection of (intra)cranial findings in adult patients following minor head injury (MHI). METHODS: The study is a prospective multicenter cohort study in the Netherlands. Consecutive MHI patients of 16 years and older were included. Primary outcome was any (intra)cranial traumatic finding on computed tomography (CT). Secondary outcomes were any potential neurosurgical lesion and neurosurgical intervention. The CHIP model was validated and subsequently updated and revised. Diagnostic performance was assessed by calculating the c-statistic. RESULTS: Among 4557 included patients 3742 received a CT (82%). In 383 patients (8.4%) a traumatic finding was present on CT. A potential neurosurgical lesion was found in 73 patients (1.6%) with 26 (0.6%) patients that actually had neurosurgery or died as a result of traumatic brain injury. The original CHIP underestimated the risk of traumatic (intra)cranial findings in low-predicted-risk groups, while in high-predicted-risk groups the risk was overestimated. The c-statistic of the original CHIP model was 0.72 (95% CI 0.69-0.74) and it would have missed two potential neurosurgical lesions and one patient that underwent neurosurgery. The updated model performed similar to the original model regarding traumatic (intra)cranial findings (c-statistic 0.77 95% CI 0.74-0.79, after crossvalidation c-statistic 0.73). The updated CHIP had the same CT rate as the original CHIP (75%) and a similar sensitivity (92 versus 93%) and specificity (both 27%) for any traumatic (intra)cranial finding. However, the updated CHIP would not have missed any (potential) neurosurgical lesions and had a higher sensitivity for (potential) neurosurgical lesions or death as a result of traumatic brain injury (100% versus 96%). CONCLUSIONS: Use of the updated CHIP decision rule is a good alternative to current decision rules for patients with MHI. In contrast to the original CHIP the update identified all patients with (potential) neurosurgical lesions without increasing CT rate.

BACKGROUND: Analysts have warned on multiple occasions that hospitals are potential soft targets for terrorist attacks. Such attacks will have far-reaching consequences, including decreased accessibility, possible casualties, and fear among people. The extent, incidence, and characteristics of terrorist attacks against hospitals are unknown. Therefore, the objective of this study was to identify and to characterize terrorist attacks against hospitals reported to the Global Terrorism Database (GTD) over a 50-year period. METHODS: The GTD was used to search for all terrorist attacks against hospitals from 1970-2019. Analyses were performed on temporal factors, location, attack and weapon type, and number of casualties or hostages. Chi-square tests were performed to evaluate trends over time and differences in attack types per world region. RESULTS: In total, 454 terrorist attacks against hospitals were identified in 61 different countries. Of these, 78 attacks targeted a specific person within the hospital, about one-half (52.6%) involved medical personnel. There was an increasing trend in yearly number of attacks from 2008 onwards, with a peak in 2014 (n = 41) and 2015 (n = 41). With 179 incidents, the "Middle East & North Africa" was the most heavily hit region of the world, followed by "South Asia" with 125 attacks. Bombings and explosions were the most common attack type (n = 270), followed by 77 armed assaults. Overall, there were 2,746 people injured and 1,631 fatalities. In three incidents, hospitals were identified as secondary targets (deliberate follow-up attack on a hospital after a primary incident elsewhere). CONCLUSION: This analysis of the GTD identified 454 terrorist attacks against hospitals over a 50-year period. It demonstrates that the threat is real, especially in recent years and in world regions where terrorism is prevalent. The findings of this study may help to create or further improve contingency plans for a scenario wherein the hospital becomes a target of terrorism.

BACKGROUND: Appropriate interpretation of vital signs is essential for risk stratification in the emergency department (ED) but may change with advancing age. In several guidelines, risk scores such as the Systemic Inflammatory Response Syndrome (SIRS) and Quick Sequential Organ Failure Assessment (qSOFA) scores, commonly used in emergency medicine practice (as well as critical care) specify a single cut-off or threshold for each of the commonly measured vital signs. Although a single cut-off may be convenient, it is unknown whether a single cut-off for vital signs truly exists and if the association between vital signs and in-hospital mortality differs per age-category. AIMS: To assess the association between initial vital signs and case-mix adjusted in-hospital mortality in different age categories. METHODS: Observational multicentre cohort study using the Netherlands Emergency Department Evaluation Database (NEED) in which consecutive ED patients ≥18 years were included between 1 January 2017 and 12 January 2020. The association between vital signs and case-mix adjusted mortality were assessed in three age categories (18-65; 66-80; >80 years) using multivariable logistic regression. Vital signs were each divided into five to six categories, for example, systolic blood pressure (SBP) categories (≤80, 81-100, 101-120, 121-140, >140 mm Hg). RESULTS: We included 101 416 patients of whom 2374 (2.3%) died. Adjusted ORs for mortality increased gradually with decreasing SBP and decreasing peripheral oxygen saturation (SpO2). Diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR) had quasi-U-shaped associations with mortality. Mortality did not increase for temperatures anywhere in the range between 35.5°C and 42.0°C, with a single cut-off around 35.5°C below which mortality increased. Single cut-offs were also found for MAP <70 mm Hg and respiratory rate >22/min. For all vital signs, older patients had larger increases in absolute mortality compared with younger patients. CONCLUSION: For SBP, DBP, SpO2 and HR, no single cut-off existed. The impact of changing vital sign categories on prognosis was larger in older patients. Our results have implications for the interpretation of vital signs in existing risk stratification tools and acute care guidelines.

Appropriate interpretation of blood tests is important for risk stratification and guidelines used in the Emergency Department (ED) (such as SIRS or CURB-65). The impact of abnormal blood test values on mortality may change with increasing age due to (patho)-physiologic changes. The aim of this study was therefore to assess the effect of age on the case-mix adjusted association between biomarkers of renal function and homeostasis, inflammation and circulation and in-hospital mortality. This observational multi-center cohort study has used the Netherlands Emergency department Evaluation Database (NEED), including all consecutive ED patients ≥ 18 years of three hospitals. A generalized additive logistic regression model was used to visualize the association between in-hospital mortality, age and five blood tests (creatinine, sodium, leukocytes, C-reactive Protein, and hemoglobin). Multivariable logistic regression analyses were used to assess the association between the number of abnormal blood test values and mortality per age category (18-50; 51-65; 66-80; > 80 years). Of the 94,974 included patients, 2550 (2.7%) patients died in-hospital. Mortality increased gradually for C-reactive Protein (CRP), and had a U-shaped association for creatinine, sodium, leukocytes, and hemoglobin. Age significantly affected the associations of all studied blood tests except in leukocytes. In addition, with increasing age categories, case-mix adjusted mortality increased with the number of abnormal blood tests. In summary, the association between blood tests and (adjusted) mortality depends on age. Mortality increases gradually or in a U-shaped manner with increasing blood test values. Age-adjusted numerical scores may improve risk stratification. Our results have implications for interpretation of blood tests and their use in risk stratification tools and acute care guidelines.Trial registration number Netherlands Trial Register (NTR) NL8422, 03/2020.

BACKGROUND AND IMPORTANCE: Although aging societies in Western Europe use presenting complaints (PCs) in emergency departments (EDs) triage systems to determine the urgency and severity of the care demand, it is unclear whether their prognostic value is age-dependent. OBJECTIVE: To assess the frequency and association of PCs with hospitalization and mortality across age categories. METHODS: An observational multicenter study using all consecutive visits of three EDs in the Netherlands Emergency department Evaluation Database. Patients were stratified by age category (0-18; 19-50; 51-65; 66-80; >80 years), in which the association between PCs and case-mix adjusted hospitalization and mortality was studied using multivariable logistic regression analysis (adjusting for demographics, hospital, disease severity, comorbidity and other PCs). RESULTS: We included 172 104 ED-visits. The most frequent PCs were 'extremity problems' [range across age categories (13.5-40.8%)], 'feeling unwell' (9.5-23.4%), 'abdominal pain' (6.0-13.9%), 'dyspnea' (4.5-13.3%) and 'chest pain' (0.6-10.7%). For most PCs, the observed and the case-mix-adjusted odds for hospitalization and mortality increased the higher the age category. The most common PCs with the highest adjusted odds ratios (AORs, 95% CI) for hospitalization were 'diarrhea and vomiting' [2.30 (2.02-2.62)] and 'feeling unwell' [1.60 (1.48-1.73)]. Low hospitalization risk was found for 'chest pain' [0.58 (0.53-0.63)] and 'palpitations' [0.64 (0.58-0.71)]. CONCLUSIONS: Frequency of PCs in ED patients varies with age, but the same PCs occur in all age categories. For most PCs, (case-mix adjusted) hospitalization and mortality vary across age categories. 'Chest pain' and 'palpitations,' usually triaged 'very urgent', carry a low risk for hospitalization and mortality.

OBJECTIVE: The aim of this study was to investigate whether sex differences exist in disease presentations, disease severity and (case-mix adjusted) outcomes in the Emergency Department (ED). METHODS: Observational multicenter cohort study using the Netherlands Emergency Department Evaluation Database (NEED), including patients ≥ 18 years of three Dutch EDs. Multivariable logistic regression was used to study the associations between sex and outcome measures in-hospital mortality and Intensive Care Unit/Medium Care Unit (ICU/MCU) admission in ED patients and in subgroups triage categories and presenting complaints. RESULTS: Of 148,825 patients, 72,554 (48.8%) were females. Patient characteristics at ED presentation and diagnoses (such as pneumonia, cerebral infarction, and fractures) were comparable between sexes at ED presentation. In-hospital mortality was 2.2% in males and 1.7% in females. ICU/MCU admission was 4.7% in males and 3.1% in females. Males had higher unadjusted (OR 1.34(1.25-1.45)) and adjusted (AOR 1.34(1.24-1.46)) risks for mortality, and unadjusted (OR 1.54(1.46-1.63)) and adjusted (AOR 1.46(1.37-1.56)) risks for ICU/MCU admission. Males had higher adjusted mortality and ICU/MCU admission for all triage categories, and with almost all presenting complaints except for headache. CONCLUSIONS: Although patient characteristics at ED presentation for both sexes are comparable, males are at higher unadjusted and adjusted risk for adverse outcomes. Males have higher risks in all triage categories and with almost all presenting complaints. Future studies should investigate reasons for higher risk in male ED patients.

BACKGROUND: Internal hospital crises and disasters (IHCDs) are events that disrupt the routine functioning of a hospital while threatening the well-being of patients and staff. IHCDs may cause hospital closure, evacuations of patients and loss of healthcare capacity. The consequences may be ruinous for local communities. Although IHCDs occur with regularity, information on the frequency and types of these events is scarcely published in the medical literature. However, gray literature and popular media reports are widely available. We therefore conducted a scoping review of these literature sources to identify and characterize the IHCDs that occurred in Dutch hospitals from 2000 to 2020. The aim is to develop a systematic understanding of the frequency of the various types of IHCDs occurring in a prosperous nation such as the Netherlands. METHODS: A systematic scoping review of news articles retrieved from the LexisNexis database, Google, Google News, PubMed and EMBASE between 2000 and 2020. All articles mentioning the closure of a hospital department in the Netherlands were analyzed. RESULTS: A total of 134 IHCDs were identified in a 20-year time period. Of these IHCDs, there were 96 (71.6%) emergency department closures, 76 (56.7%) operation room closures, 56 (41.8%) evacuations, 26 (17.9%) reports of injured persons, and 2 (1.5%) reported casualties. Cascading events of multiple failures transpired in 39 (29.1%) IHCDs. The primary causes of IHCDs (as reported) were information and communication technology (ICT) failures, technical failures, fires, power failures, and hazardous material warnings. An average of 6.7 IHCDs occurred per year. From 2000-2009 there were 32 IHCDs, of which one concerned a primary ICT failure. Of the 102 IHCDs between 2010-2019, 32 were primary ICT failures. CONCLUSIONS: IHCDs occur with some regularity in the Netherlands and have marked effects on hospital critical care departments, particularly emergency departments. Cascading events of multiple failures transpire nearly a third of the time, limiting the ability of a hospital to stave off closure due to failure. Emergency managers should therefore prioritize the risk of ICT failures and cascading events and train hospital staff accordingly.

BACKGROUND AND IMPORTANCE: Healthcare personnel working in the emergency department (ED) is at risk of acquiring severe acute respiratory syndrome coronavirus-2 (SARS-Cov-2). So far, it is unknown if the reported variety in infection rates among healthcare personnel is related to the use of personal protective equipment (PPE) or other factors. OBJECTIVE: The aim of this study was to investigate the association between PPE use and SARS-CoV-2 infections among ED personnel in the Netherlands. DESIGN, SETTING AND PARTICIPANTS: A nationwide survey, consisting of 42 questions about PPE-usage, ED layout - and workflow and SARS-CoV-2 infection rates of permanent ED staff, was sent to members of the Dutch Society of Emergency Physicians. Members were asked to fill out one survey on behalf of the ED of their hospital. The association between PPE use and the infection rate was investigated using univariable and multivariable regression analyses, adjusting for potential confounders. OUTCOME MEASURES: Primary outcome was the incidence of confirmed SARS-CoV-2 infections among permanent ED staff between 1 March and 15 May 2020. RESULTS: Surveys were sent to 64 EDs of which 45 responded (70.3%). In total, 164 ED staff workers [5.1 (3.2-7.0)%] tested positive for COVID-19 during the study period compared to 0.087% of the general population. There was significant clustering of infected ED staff in some hospitals (range: 0-23 infection). In 13 hospitals, an FFP2 (filtering facepiece particles >94% aerosol filtration) mask or equivalent and eye protection was worn for all contacts with patients with suspected or confirmed SARS-CoV-2 during the whole study period. The unadjusted staff infection rate was higher in these hospitals [7.3 (3.4-11.1) vs. 4.0 (1.9-6.1)%, absolute difference + 3.3%]. Hospital staff testing policy was identified as a potential confounder of the relation between PPE use and confirmed SARS-CoV-2 infections (collinearity statistic 0.95). After adjusting for hospital testing policy, type of PPE was not associated with incidence of COVID 19 infections among ED staff (P = 0.40). CONCLUSION: In this cross-sectional study, the use of high-level PPE (FFP2 or equivalent and eye protection) by ED personnel during all contacts with patients with suspected or confirmed SARS-CoV-2 does not seem to be associated with a lower infection rate of ED staff compared to lower level PPE use. Attention should be paid to ED layout and social distancing to prevent cross-contamination of ED personnel.

OBJECTIVE: In the past 10 years, there has been a decrease in the number of patients who report to the Emergency Department (ED) every year for injuries from accidents or violence, especially in the subgroup of patients who did not require hospital admission. We investigated how the number of injury-related emergency department visits and GP contacts evolved over the period 2013-2017. DESIGN: Retrospective observational trend study. METHOD: To calculate the trend in emergency department visits in the Netherlands, we used data from the injury information system (LIS) for the period 2013-2017. To calculate the trend in GP contacts (GP practices as well as GP centres), we used data from the NivelZorgregistraties (Nivel medical records). In order to compare the trends, we distinguished between minor and major injuries. The numbers from the records were extrapolated to numbers for the whole of the Netherlands. RESULTS: In the period studied, the number of patients with minor injuries who visited the ED dropped by 38.5%, while the number of patients with major injuries (fractures and brain injuries) increased by 4.1%. In the same period, the number of GP contacts for minor injuries at GP practices increased by 25% and at GP centres by 43%; the number of primary care contacts for major injuries increased by 5.1% (GP practices) and 31% (GP centres) respectively. CONCLUSION: The role of general practitioners in the treatment of patients with minor injuries is increasing. The trend in major injuries is a better indicator for monitoring accidents and violence in the Netherlands. Conflict of interest and financial support: none declared.

BACKGROUND: A proper application of the Delphi technique is essential for obtaining valid research results. Medical researchers regularly use Delphi studies, but reports often lack detailed information on methodology and controlled feedback: in the medical literature, papers focusing on Delphi methodology issues are rare. Since the introduction of electronic surveys, details on response times remain scarce. We aim to bridge a number of gaps by providing a real world example covering methodological choices and response times in detail. METHODS: The objective of our e(lectronic)-Delphi study was to determine minimum standards for emergency departments (EDs) in the Netherlands. We opted for a two-part design with explicit decision rules. Part 1 focused on gathering and defining items; Part 2 addressed the main research question using an online survey tool. A two-person consensus rule was applied throughout: even after consensus on specific items was reached, panellists could reopen the discussion as long as at least two panellists argued similarly. Per round, the number of reminders sent and individual response times were noted. We also recorded the methodological considerations and evaluations made by the research team prior to as well as during the study. RESULTS: The study was performed in eight rounds and an additional confirmation round. Response rates were 100% in all rounds, resulting in 100% consensus in Part 1 and 96% consensus in Part 2. Our decision rules proved to be stable and easily applicable. Items with negative advice required more rounds before consensus was reached. Response delays were mostly due to late starts, but once panellists started, they nearly always finished the questionnaire on the same day. Reminders often yielded rapid responses. Intra-individual differences in response time were large, but quick responders remained quick. CONCLUSIONS: We advise those considering Delphi study to follow the CREDES guideline, consider a two-part design, invest in personal commitment of the panellists, set clear decision rules, use a consistent lay-out and send out your reminders early. Adopting this overall approach may assist researchers in future Delphi studies and may help to improve the quality of Delphi designs in terms of improved rigor and higher response rates.

OBJECTIVES: Emergency medicine (EM) in the Netherlands has developed rapidly and initially without central guidance. This has led to heterogeneity in current EM practice. Our aim was to quantify this heterogeneity by answering the following questions: (1) What is the current position of emergency physicians (EPs) within hospital organizations? (2) Which roles and responsibilities do EPs have across emergency departments (EDs)? METHODS: During 2018, we conducted a survey among all EM consultant bodies (CBs, n = 56) in the Netherlands. Data was analyzed using descriptive statistics. RESULTS: The response rate was 91.1%. Presence of EPs has been realized 24/7 in 23.1% of EDs. EPs were the main consultants for all ED patients in 9.8% of CBs, but never had this role in 13.7% of CBs. EPs supervised EM junior doctors in 78.5% of EDs, GPs in training in 80.0% of EDs, and junior doctors of other specialties in 41.5% of EDs. Procedures such as lumbar puncture (LP), procedural sedation and analgesia (PSA), and emergency ultrasound (US) were performed by all EPs in the CB in a range between 5.9 and 78.4%. In 36.9% of EDs, EPs did not analyze patients with presumed cardiac pathology due to a separate First Heart Aid. CONCLUSION: We conclude that there is a high degree of heterogeneity between emergency CBs in regard to the position in the hospital and the role or responsibilities in the ED. Lack of uniformity might inhibit emancipation of the profession.
RESUMEN
OBJECTIVE: The objective of this study was to effectuate a consensus of emergency physicians on minimum requirements for facility, diagnostic, and medical specialist availability as a first step toward minimum operational standards for 24/7 available emergency departments (EDs) in the Netherlands. PATIENTS AND METHODS: A two-part e-Delphi through online survey was performed between January 2015 and May 2016, using a panel of 20 experts in emergency medicine. The aim of part I was to reach an agreement on a list of possible ED elements and their definitions. The second part addressed the actual study objective to reach consensus on operational standards. Successive rounds were submitted to the members of the panel online using SurveyMonkey. Results of each survey round were discussed and interpreted in agreement with all authors in preparation for the next round. Reaching consensus, defined as 70% or more agreement or disagreement among the panel, on the level of all items was the endpoint of this study. RESULTS: Both parts I and II required five rounds. The dropout rate of the expert panel remained zero. The availability of 52 facilities and diagnostic functionalities and the manner in which 17 medical specialties should be available to every 24/7 ED were agreed upon by the expert panel. CONCLUSION: An expert panel agreed upon minimum operational standards for EDs in the Netherlands. These results are helpful as a first step toward a more widely supported standard for future 24/7 available EDs in the Netherlands and in addition to this other urgent care facilities.

OBJECTIVE: To externally validate four commonly used rules in computed tomography (CT) for minor head injury. DESIGN: Prospective, multicentre cohort study. SETTING: Three university and six non-university hospitals in the Netherlands. PARTICIPANTS: Consecutive adult patients aged 16 years and over who presented with minor head injury at the emergency department with a Glasgow coma scale score of 13-15 between March 2015 and December 2016. MAIN OUTCOME MEASURES: The primary outcome was any intracranial traumatic finding on CT; the secondary outcome was a potential neurosurgical lesion on CT, which was defined as an intracranial traumatic finding on CT that could lead to a neurosurgical intervention or death. The sensitivity, specificity, and clinical usefulness (defined as net proportional benefit, a weighted sum of true positive classifications) of the four CT decision rules. The rules included the CT in head injury patients (CHIP) rule, New Orleans criteria (NOC), Canadian CT head rule (CCHR), and National Institute for Health and Care Excellence (NICE) guideline for head injury. RESULTS: For the primary analysis, only six centres that included patients with and without CT were selected. Of 4557 eligible patients who presented with minor head injury, 3742 (82%) received a CT scan; 384 (8%) had a intracranial traumatic finding on CT, and 74 (2%) had a potential neurosurgical lesion. The sensitivity for any intracranial traumatic finding on CT ranged from 73% (NICE) to 99% (NOC); specificity ranged from 4% (NOC) to 61% (NICE). Sensitivity for a potential neurosurgical lesion ranged between 85% (NICE) and 100% (NOC); specificity from 4% (NOC) to 59% (NICE). Clinical usefulness depended on thresholds for performing CT scanning: the NOC rule was preferable at a low threshold, the NICE rule was preferable at a higher threshold, whereas the CHIP rule was preferable for an intermediate threshold. CONCLUSIONS: Application of the CHIP, NOC, CCHR, or NICE decision rules can lead to a wide variation in CT scanning among patients with minor head injury, resulting in many unnecessary CT scans and some missed intracranial traumatic findings. Until an existing decision rule has been updated, any of the four rules can be used for patients presenting minor head injuries at the emergency department. Use of the CHIP rule is recommended because it leads to a substantial reduction in CT scans while missing few potential neurosurgical lesions.

INTRODUCTION: Previous studies indicate that crowding scales may not perform well in low-volume emergency departments (EDs). In this study, face-validity of the Modified National ED OverCrowding Score (mNEDOCS) was assessed in a high-volume ED as well as in a low-volume ED. METHODS: A prospective observational cohort study was performed in the Netherlands. The correlation of the mNEDOCS with ED staff perceptions of crowding were assessed, using weighted Kappa (κ) and Pearson correlation. Subsequently, ED process measures (elapsed target times to triage, elapsed target times to treatment and patients' LOS) were described under different levels of ED crowding. RESULTS: Correlation between the categorized crowding scores was low (weighted κ 0.34 resp. 0.26). However, good correlations of 0.73 and 0.82 were found between the uncategorized mNEDOCS and ED staff's perception of crowding. Percentages of patients with elapsed target times to treatment increased simultaneously with increasingly busy periods when measured with mNEDOCS. CONCLUSIONS: The uncategorized mNEDOCS correlates well with perceived crowding, even at a low-volume ED. Determining a cut-off level at which a specific ED can be identified as crowded is important, because the predefined mNEDOCS categories may not be optimal for all EDs.
