RESUMO
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: During closed reduction of displaced distal radius fractures, physical examination is used to determine the need for further manipulation before radiographic confirmation and cast application. Manipulation performed under ultrasound guidance has the potential to decrease the number of reduction attempts. METHODS: This multicentre randomised controlled trial was undertaken between December 2018 and July 2020 in the ED of four hospitals in the Netherlands. Patients aged ≥16 years presenting to the ED with a distal radius fracture requiring closed reduction were randomised to either point-of-care ultrasound (PoCUS)-guided or standard reduction. The primary outcome was the proportion of patients requiring more than one reduction attempt. The secondary outcomes were time to complete reduction and treatment plan at ED discharge (conservative or operative repair). RESULTS: A total of 214 patients were screened, of which 211 patients were included for primary endpoint analysis (87% female, median age 68 years, 94% dorsal angulation, 59% intra-articular and 73% multifragmentary). In total, 105 patients were randomised to standard treatment and 106 patients to PoCUS-guided fracture reduction. In the standard treatment group, 13 patients (12%) required more than one reduction attempt, compared with 6 patients (6%) in the PoCUS group (OR 2.35, 95% CI 0.86 to 6.45). The median reduction time was 5 min in the PoCUS group (IQR 3-6) vs 3 min (IQR 2-4) in the standard reduction group (p<0.001). At ED discharge, operative repair was indicated for 17 (16%) patients in the standard group and 21 (20%) patients in the PoCUS group (OR 0.78, 95% CI 0.39 to 1.58). CONCLUSION: This study could not demonstrate that PoCUS-guided reduction of distal radius fractures was associated with a statistically significant decrease in the number of reduction attempts. TRIAL REGISTRATION NUMBER: The Netherlands Trial Register (NTR7934).

Procedural sedation is routinely performed for procedures in the emergency department (ED). Propofol is a commonly used sedative, frequently combined with an opioid or low-dose ketamine as an analgesic. However, there is still controversy on the optimal combination of agents in current guidelines. The objective of this systematic review is to identify and present studies comparing low-dose ketamine to opioids when combined with propofol for procedural sedation in the ED and to describe the dosing regimen, observed efficacy, and side effects. For this systematic review, following the Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines, EMBASE and PubMed databases were searched. Studies comparing propofol with opioids versus propofol with low-dose (es)ketamine in patients undergoing procedural sedation for procedures in the ED were included. Analyses were descriptive because of the high heterogeneity among included studies. The outcomes were dosing regimen, efficacy of analgesia, efficacy of sedation depth, efficacy of recovery and (adverse) events. We included four out of 2309 studies found in the literature search. Overall, the studies had a low risk of bias, but the Grading of Recommendations Assessment, Development, and Evaluation evidence profile was downgraded due to the imprecision and inconsistency of the studies. All studies compared low-dose ketamine with fentanyl. Dosing ranged from 0.3 to 1.0 mg/kg (ketamine), 1.0-1.5 µg/kg (fentanyl) and 0.4-1.0 mg/kg (propofol). The efficacy of analgesia was measured by two studies, one favoring the fentanyl group, and one favoring the ketamine group. The efficacy of sedation depth was measured by one study, with the fentanyl group having a deeper sedation score. Two studies showed shorter recovery time with low-dose ketamine. One study showed a higher incidence of cardio-respiratory clinical events and interventions in the fentanyl group. Two studies showed significant differences of overall sedation events in the fentanyl group. One study did not find any significant differences of the incidence of sedation events. This systematic review did not provide sufficient evidence that the combination of low-dose ketamine and propofol is associated with a shorter recovery time and fewer sedation events compared to the combination of opioids and propofol.

OBJECTIVES: This study aimed to evaluate the adherence to protocols for the use of reversal agents in direct oral anticoagulant (DOAC) users in Dutch hospitals. METHODS: A retrospective cohort study was conducted in seven hospitals in the Netherlands. Treatment protocols for bleeding and (urgent) procedures in patients on DOAC were collected from each hospital. All patient data on the use of reversal agents were retrospectively collected from September 2021 to April 2022 and compared to the protocols. The degree of per-protocol adherence (compliance score) was categorized into four levels as follows: poor (<45%), moderate (45-79%), high (80-89%), and full (> 90%) adherence rates. RESULTS: A total of 290 patients were included in our study. In patients with bleeding under DOAC, the protocol adherence for prothrombin complex concentrate (PCC) was "moderate" (61%). In the remaining cases (39%), non-adherence was mainly caused by underdosing (68%), overdosing (12%), and a lack of indication (14%). Furthermore, idarucizumab was administered for bleeding with "full" adherence (96%). For andexanet alfa, adherence to the hospital bleeding protocol was "moderate" (67%), with a lack of indication being the only reason for non-adherence. In case of reversal for an urgent procedure, the protocol adherence for PCC was "low" (45%), with underdosing, a lack of indication, and missing lab data being the main reasons for non-adherence. Missing lab data on dabigatran plasma concentration before reversal was the main reason for "low" adherence (26%) in idarucizumab. The adherence for andexanet alfa was also "low" (0%). CONCLUSION: In case of reversal for bleeding under DOAC, overall adherence to the protocol was "moderate"; however, in patients needing an urgent procedure, it was "low." The major reasons for non-adherence were underdosing, off-label use, and a lack of specific lab testing. The results of this study can assist in improving the implementation of hospital protocols.

BACKGROUND: The ROX index combines respiratory rate and oxygenation to predict the response to oxygen therapy in pneumonia. It is calculated by dividing the patient's oxygen saturation, by the inspired oxygen concentration, and then by the respiratory rate (e.g. 95%/0.21/16 = 28). Since this index includes the most essential physiological variables to detect deterioration, it may be a helpful risk tool in the emergency department (ED). Although small studies suggest it can predict early mortality, no large study has compared it with the National Early Warning Score (NEWS), the most widely validated risk score for death within 24 h. AIM: The aim of this study was to compare the ability of the ROX index with the NEWS to predict mortality within 24 h of arrival at the hospital. METHODS: This was a retrospective observational multicentre analysis of data in the Netherlands Emergency Department Evaluation Database (NEED) on 270 665 patients attending four participating Dutch EDs. The ROX index and NEWS were determined on ED arrival and prior to ED treatment. RESULTS: The risk of death within 24 h increased with falling ROX and rising NEWS values. The area under the receiving operating characteristic curves for 24-h mortality of NEWS was significantly higher than for the ROX index [0.92; 95% confidence interval (CI), 0.91-0.92 versus 0.87; 95% CI, 0.86-0.88; P < 0.01]. However, the observed and predicted mortality by the ROX index was identical to mortality of 5%, after which mortality was underestimated. In contrast, up to a predicted 24-h mortality of 3% NEWS slightly underestimates mortality, and above this level over-estimates it. The standardized net benefit of ROX is slightly higher than NEWS up to a predicted 24-h mortality of 3%. CONCLUSION: The prediction of 24-h mortality by the ROX index is more accurate than NEWS for most patients likely to be encountered in the ED. ROX may be used as a first screening tool in the ED.

OBJECTIVE: To investigate and describe the protocolized treatment of DOAC-related bleeds in all Dutch hospitals. METHODS: From August to December 2020 a nationwide survey among all 70 hospitals in the Netherlands was conducted on their protocols for management of bleeding in patients treated with direct oral anticoagulants (DOACs, i.e. apixaban, edoxaban, rivaroxaban and dabigatran). The protocols were assessed the following characteristics: bleeding definitions (mild, moderate and severe bleed), diagnostic parameters (hemoglobin [Hb], loss of blood, surgical procedure needed, etc), first and second choice of treatment, effectiveness criteria and the level of evidence/references upon which protocols were based. RESULTS: All 70 hospitals responded (100%). We received 69 protocols in total, 6 of which were identical because hospitals worked together. In 35 (50%) of the protocols a definition of minor, moderate or severe bleeds was described. Diagnostic parameters for bleeds were present in 2%, 41% and 47% of protocols for a mild, moderate and severe bleed. While the first choice treatment for severe bleeding under dabigatran was idarucizumab in 96% of protocols, considerably more therapeutic options (mostly different prothrombin complex concentrate (PCC) doses) are described for Xa inhibitors. When considering criteria for effectiveness more than 90% of protocols did not have a clear description. CONCLUSION: This study provides an overview of the current state of protocols for management of DOAC-related bleeding in The Netherlands. Protocols vary in the content of information provided and often do not include information, especially for diagnostic criteria and criteria for establishing the effectiveness of the intervention. The results of this study can assist in improving and harmonizing the protocols.

OBJECTIVES: To investigate and describe the protocolized perioperative management in patient using Direct oral anticoagulants (DOACs) in Dutch hospitals. METHODS: Between August and December 2020, a nationwide survey in 70 hospitals in the Netherlands was conducted. We asked hospital pharmacists to submit their protocols for perioperative management of DOAC (apixaban, dabigatran, edoxaban and rivaroxaban) users. The protocols were assessed for a number of parameters divided into categories: interruption and restart timetables DOACs for elective procedures, criteria for the start of an urgent procedure without antidotes, criteria for the use of antidotes and advised antidotes for urgent procedures. RESULTS: A total of 49 hospitals (70%) sent a protocol for perioperative management of DOACs. Two pairs of protocols were identical because hospitals cooperated closely, leaving 47 individual protocols for analysis. Thirty-five of these protocols contained a policy for both elective and urgent procedure; five protocols contained only a policy for elective and seven only for urgent procedures. In protocols for elective procedure, we found great variation in interruption and restart timetables intended for patients with renal impairment (Estimated Glomerular Filtration Ratio < 80 ml/min). In case of urgent procedures, there is variation in choice of antidote, criteria for administration of an antidote and antidote dosing. CONCLUSION: This study provides an overview of the current state of the perioperative protocols in the Netherlands in patients treated with direct oral anticoagulants. Protocols are often not complete and show important and unwanted variation. We have found that national guidelines do not provide unambiguous advice on all points (urgent procedures) and are therefore often elaborated at a local level. The results of this research can help in improving and harmonizing the perioperative protocols on a national level.

Previous studies show that prolonged exposure to a high inspired oxygen concentration (FiO2) is associated with unfavourable haemodynamic effects. Until now, it is unknown if similar effects also occur after oxygen therapy of limited duration in the emergency department (ED). OBJECTIVES: To investigate the haemodynamic effects of a high FiO2 administered for a limited duration of time in patients who receive preoxygenation for procedural sedation and analgesia (PSA) in the ED. DESIGN, SETTINGS AND PARTICIPANTS: In a prospective cohort study, cardiac output (CO), stroke volume (SV) and systemic vascular resistance (SVR) were measured using the Clearsight non-invasive CO monitoring system in patients who received preoxygenation for PSA in the ED. Measurements were performed at baseline, after 5 min of preoxygenation via a non-rebreathing mask at 15 /L min and after 5 min of flush rate oxygen administration. OUTCOMES MEASURES: The primary outcome was defined as the change in CO (L/min) from baseline after subsequent preoxygenation with 15 L/min and flush rate. RESULTS: Sixty patients were included. Mean CO at baseline was 6.5 (6.0-6.9) L/min and decreased to 6.3 (5.8-6.8) L/min after 5 min of oxygen administration at a rate of 15 L/min, and to 6.2 (5.7-6.70) L/min after another 5 min at flush rate (p=0.037). Mean SV remained relatively constant during this period, whereas mean SVR increased markedly (from 781 (649-1067), to 1244 (936-1695) to 1337 (988-1738) dyn/s/cm-5, p<0.001. Sixteen (27%) patients experienced a>10% decrease in CO. CONCLUSION: Exposure of patients to a high FiO2 for 5-10 min results in a significant drop in CO in one out of four patients. Therefore, even in the ED and in prehospital care, where oxygen is administered for a limited amount of time, FiO2 should be titrated based on deficit whenever this is feasible and high flow oxygen should not be given as a routine treatment.

BACKGROUND: There is a lack of rapid, non-invasive tools that aid early prognostication in patients with return of spontaneous circulation (ROSC) after Out-of-Hospital Cardiac Arrest (OHCA). The shock index (SI) and modified shock index (MSI) have shown to be useful in several medical conditions, including myocardial infarction. In this study, we assessed the prognostic value of SI and MSI at Emergency Department (ED) triage on survival to discharge of OHCA patients. METHODS: A single-center retrospective observational cohort study. All OHCA patients with a period of ROSC between 2014 and 2019 were included. Data collection was based on the Utstein criteria. The SI and MSI at ED triage were calculated by dividing heart rate by systolic blood pressure or mean arterial pressure. Survival rates were compared between patients with a high and low SI and MSI. Subsequent Cox regression analysis was performed. MAIN RESULTS: A total of 403 patients were included, of which 46% survived until hospital discharge. An elevated SI and MSI was defined by SI ≥ 1.00 and MSI ≥ 1.30. Survival to discharge, 30-day- and one-year survival were significantly lower in patients with an elevated SI and MSI (p < 0.001). An elevated SI and MSI was also associated with a higher rate of recurrent loss of circulation in the ED (p < 0.001). The 30-day survival hazard ratio was 2.24 (1.56-3.22) for SI and 2.46 (1.71-3.53) for MSI; the one-year survival hazard ratio was 2.20 (1.54-3.15) for SI and 2.38 (1.66-3.40) for MSI. CONCLUSION: Survival to discharge and 30-day survival are lower in OHCA patients with an elevated SI and MSI at ED triage. Further studies are warranted to elucidate the causational mechanisms underlying the association between elevated SI or MSI and worse outcomes.

BACKGROUND: Treatment and the clinical course during Emergency Department (ED) stay before Intensive Care Unit (ICU) admission may affect predicted mortality risk calculated by the Acute Physiology and Chronic Health Evaluation (APACHE)-IV, causing lead-time bias. As a result, comparing standardized mortality ratios (SMRs) among hospitals may be difficult if they differ in the location where initial stabilization takes place. The aim of this study was to assess to what extent predicted mortality risk would be affected if the APACHE-IV score was recalculated with the initial physiological variables from the ED. Secondly, to evaluate whether ED Length of Stay (LOS) was associated with a change (delta) in these APACHE-IV scores. METHODS: An observational multicenter cohort study including ICU patients admitted from the ED. Data from two Dutch quality registries were linked: the Netherlands Emergency department Evaluation Database (NEED) and the National Intensive Care Evaluation (NICE) registry. The ICU APACHE-IV, predicted mortality, and SMR based on data of the first 24 h of ICU admission were compared with an ED APACHE-IV model, using the most deviating physiological variables from the ED or ICU. RESULTS: A total of 1398 patients were included. The predicted mortality from the ICU APACHE-IV (median 0.10; IQR 0.03-0.30) was significantly lower compared to the ED APACHE-IV model (median 0.13; 0.04-0.36; p < 0.01). The SMR changed from 0.63 (95%CI 0.54-0.72) to 0.55 (95%CI 0.47-0.63) based on ED APACHE-IV. Predicted mortality risk changed more than 5% in 321 (23.2%) patients by using the ED APACHE-IV. ED LOS > 3.9 h was associated with a slight increase in delta APACHE-IV of 1.6 (95% CI 0.4-2.8) compared to ED LOS < 1.7 h. CONCLUSION: Predicted mortality risks and SMRs calculated by the APACHE IV scores are not directly comparable in patients admitted from the ED if hospitals differ in their policy to stabilize patients in the ED before ICU admission. Future research should focus on developing models to adjust for these differences.

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.

STUDY OBJECTIVE: To determine if a fixed dose of 1000 IU of 4-factor prothrombin complex concentrate (4F-PCC) is as effective as traditional variable dosing based on body weight and international normalized ratio (INR) for reversal of vitamin K antagonist (VKA) anticoagulation. METHODS: In this open-label, multicenter, randomized clinical trial, patients with nonintracranial bleeds requiring VKA reversal with 4F-PCC were allocated to either a 1,000-IU fixed dose of 4F-PCC or the variable dose. The primary outcome was the proportion of patients with effective hemostasis according to the International Society of Thrombosis and Haemostasis definition. The design was noninferiority with a lower 95% confidence interval of no more than -6%. When estimating sample size, we assumed that fixed dosing would be 4% superior. RESULTS: From October 2015 until January 2020, 199 of 310 intended patients were included before study termination due to decreasing enrollment rates. Of the 199 patients, 159 were allowed in the per-protocol analysis. Effective hemostasis was achieved in 87.3% (n=69 of 79) in fixed compared to 89.9% (n=71 of 79) in the variable dosing cohort (risk difference 2.5%, 95% confidence interval -13.3 to 7.9%, P=.27). Median door-to-needle times were 109 minutes (range 16 to 796) in fixed and 142 (17 to 1076) for the variable dose (P=.027). INR less than 2.0 at 60 minutes after 4F-PCC infusion was reached in 91.2% versus 91.7% (P=1.0). CONCLUSION: The large majority of patients had good clinical outcome after 4F-PCC use; however, noninferiority of the fixed dose could not be demonstrated because the design assumed the fixed dose would be 4% superior. Door-to-needle time was shortened with the fixed dose, and INR reduction was similar in both dosing regimens.

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.

OBJECTIVE: Early identification of emergency department (ED) patients who need hospitalization is essential for quality of care and patient safety. We aimed to compare machine learning (ML) models predicting the hospitalization of ED patients and conventional regression techniques at three points in time after ED registration. METHODS: We analyzed consecutive ED patients of three hospitals using the Netherlands Emergency Department Evaluation Database (NEED). We developed prediction models for hospitalization using an increasing number of data available at triage, â¼30 min (including vital signs) and â¼2 h (including laboratory tests) after ED registration, using ML (random forest, gradient boosted decision trees, deep neural networks) and multivariable logistic regression analysis (including spline transformations for continuous predictors). Demographics, urgency, presenting complaints, disease severity and proxies for comorbidity, and complexity were used as covariates. We compared the performance using the area under the ROC curve in independent validation sets from each hospital. RESULTS: We included 172,104 ED patients of whom 66,782 (39 %) were hospitalized. The AUC of the multivariable logistic regression model was 0.82 (0.78-0.86) at triage, 0.84 (0.81-0.86) at â¼30 min and 0.83 (0.75-0.92) after â¼2 h. The best performing ML model over time was the gradient boosted decision trees model with an AUC of 0.84 (0.77-0.88) at triage, 0.86 (0.82-0.89) at â¼30 min and 0.86 (0.74-0.93) after â¼2 h. CONCLUSIONS: Our study showed that machine learning models had an excellent but similar predictive performance as the logistic regression model for predicting hospital admission. In comparison to the 30-min model, the 2-h model did not show a performance improvement. After further validation, these prediction models could support management decisions by real-time feedback to medical personal.

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.
