Procalcitonin for safe reduction of unnecessary blood cultures in the emergency department: Development and validation of a prediction model

Blood cultures (BCs) are commonly ordered in emergency departments (EDs), while a minority yields a relevant pathogen. Diagnostic stewardship is needed to safely reduce unnecessary BCs. We aimed to develop and validate a bacteremia prediction model for ED patients, with specific focus on the benefit of incorporating procalcitonin. We included adult patients with suspected bacteremia from a Dutch ED for a one-year period. We defined 23 candidate predictors for a "full model", of which nine were used for an automatable "basic model". Variations of both models with C-reactive protein and procalcitonin were constructed using LASSO regression, with bootstrapping for internal validation. External validation was done in an independent cohort of patients with confirmed infection from 71 Spanish EDs. We assessed discriminative performance using the C-statistic and calibration with calibration curves. Clinical usefulness was evaluated by sensitivity, specificity, saved BCs, and Net Benefit. Among 2111 patients in the derivation cohort (mean age 63 years, 46% male), 273 (13%) had bacteremia, versus 896 (20%) in the external cohort (n=4436). Adding procalcitonin substantially improved performance for all models. The basic model with procalcitonin showed most promise, with a C-statistic of 0.87 (0.86-0.88) upon external validation. At a 5% risk threshold, it showed a sensitivity of 99% and could have saved 29% of BCs while only missing 10 out of 896 (1.1%) bacteremia patients. Procalcitonin-based bacteremia prediction models can safely reduce unnecessary BCs at the ED. Further validation is needed across a broader range of healthcare settings.

Factors associated with dischargehome in older patients admitted to emergency department observation units: Lookingfor a predictive scale.

The selection of patients who are going to be admitted to an emergency department observation unit (EDOU) is essential for the good management of these units, intended fundamentally to avoid unnecessary hospitalization of patients. This is especially important when dealing with older patients. It would be important to know what factors are associated with discharge home and to have a clinical predictive scale that appropriately selects older patients who are going to be admitted to an EDOU. A retrospective cross-sectional study was conducted of all patients ≥65 years of age assisted in 48 Spanish Emergency Departments for 7 consecutive days and were admitted to the EDOU. Demographics-functional, vital signs data and initial laboratory results were analyzed to investigate its association with discharge home and develop and validate a prediction model for discharge home from EDOU. Multivariable logistic regression was performed to develop a prediction model, and a scoring system was created. Among 5457 patients admitted to the EDOU from the emergency room, 2508 (46%) patients were discharged home, and 2949 (54%) were admitted to the hospital. Five variables were strongly associated with discharge home: the absence of fever (adjusted OR: 3.61, 95% CI:1.53-8.54), Glasgow Coma Scale score of 15 points (2.80, 1.63-4.82), absence of tachypnea (2.51, 1.74-3.64) or leukocytosis (2.07, 1.70-2.52) and oxygen saturation >94% (2.00, 1.64-2.43). The final model achieved an area under the receiver operating characteristic curve of 0.648 (IC95% = 0.627-0.668) in the development cohort and 0.635 (0.614-0.656) in the validation cohort. There are factors associated with a greater probability of discharge home of older patients admitted to EDOUs. Prediction at the individual level remains elusive, as the best model obtained in this study did not have sufficient validity to be applied in the clinical setting.

How organisational factors and clinical decision support system affect nurses’ knowledge for decisions in triage

ABSTRACT This paper delves into heuristic decision-making by nurses during the triage process, aiming to elucidate how organisational factors influence nurses’ decision-making regarding the assignment of priority codes to patients, and to assess the effectiveness of Clinical Decision Support Systems (CDSS) in this context. Drawing on an experimental dataset of 25 triage cases evaluated by 35 nurses via interviews, the study was conducted in two Spanish Emergency Departments using CDSS. Findings indicate that organisational factors predominantly influence decisions in cases with complete and coherent information. However, in cases where information is incoherent or missing, individual nurse characteristics guide decision-making. Furthermore, it suggests that CDSS should be tailored to nurses’ clinical reasoning to serve as effective support for individual decision-making processes.

Association of intravenous digoxin use in acute heart failure with rapid atrial fibrillation and short-term mortality according to patient age, renal function, and serum potassium.

Intravenous digoxin is still used in emergency departments (EDs) to treat patients with acute heart failure (AHF), especially in those with rapid atrial fibrillation. Nonetheless, many emergency physicians are reluctant to use intravenous digoxin in patients with advanced age, impaired renal function, and potassium disturbances due to its potential capacity to increase adverse outcomes. We investigated whether intravenous digoxin used to treat rapid atrial fibrillation in patients with AHF may influence mortality in patients with specific age, estimated glomerular filtration rate (eGFR), and serum potassium classes. A secondary analysis of patients included in in the Spanish EAHFE cohort, which includes patients diagnosed with AHF in the ED. 45 Spanish EDs. Two thousand one hundred ninety-four patients with AHF and rapid atrial fibrillation (heart rate ≥100 bpm) not receiving digoxin at home, divided according to whether they were or were not treated with intravenous digoxin in the ED. The relationships between age, eGFR, and potassium with 30-day mortality were investigated using restricted cubic spline (RCS) models adjusted for relevant patient and episode variables. The impact of digoxin use on such relationships was assessed by checking interaction. The median age of the patients was 82 years [interquartile range (IQR) = 76-87], 61.4% were women, 65.2% had previous episodes of atrial fibrillation, and the median heart rate at ED arrival was 120 bpm (IQR = 109-135). Digoxin and no digoxin groups were formed by 864 (39.4%) and 1330 (60.6%) patients, respectively. There were 191 deaths within the 30-day follow-up period (8.9%), with no differences between patients receiving or not receiving digoxin (8.5 vs. 9.1%, P = 0.636). Although analysis of RCS curves showed that death was associated with advanced age, worse renal function, and hypo- and hyperkalemia, use of intravenous digoxin did not interact with any of these relationships ( P = 0.156 for age, P = 0.156 for eGFR; P = 0.429 for potassium). The use of intravenous digoxin in the ED was not associated with significant changes in 30-day mortality, which was confirmed irrespective of patient age or the existence of renal dysfunction or serum potassium disturbances.

Use of diagnostic tests in elderly patients consulting the emergency department. Analysis of the emergency department and elder needs cohort (EDEN-8)

ObjectiveAnalyse the association between the use of diagnostic tests and the characteristics of older patients 65 years of age or more who consult the emergency department (ED). MethodsWe performed an analysis of the EDEN cohort that includes patients who consulted 52 Spanish EDs. The association of age, sex, and ageing characteristics with the use of diagnostic tests (blood tests, electrocardiogram (ECG), microbiological cultures, X-ray, computed tomography, ultrasound, invasive techniques) was studied. The association was analysed by calculating the adjusted odds ratios (aOR) and their 95 % confidence intervals (CI) using a logistic regression model. ResultsA total of 25,557 patients were analysed. There was an increase in the use of diagnostic tests based on age, with an aOR for blood test of 1.805 (95 %CI 1.671 – 1.950), ECG 1.793 (95 %CI 1.664 – 1.932) and X-ray 1.707 (95 %CI 1.583 – 1.840) in the group of 85 years or more. The use of diagnostic tests is lower in the female population. Most ageing characteristics (cognitive impairment, previous falls, polypharmacy, dependence, and comorbidity) were independently associated with increased use of diagnostic tests. ConclusionsAge, and the characteristics of ageing itself are generally associated with a greater use of diagnostic tests in the ED.

Overnight stay in Spanish emergency departments and mortality in older patients.

To assess whether older adults who spend a night in emergency departments (ED) awaiting admission are at increased risk of mortality. This was a retrospective review of a multipurpose cohort that recruited all patients ≥ 75years who visited ED and were admitted to hospital on April 1 to 7, 2019, at 52 EDs across Spain. Study groups were: patients staying in ED from midnight until 8:00 a.m. (ED group) and patients admitted to a ward before midnight (ward group). The primary endpoint was in-hospital mortality, truncated at 30days, and secondary outcomes assessed length of stay for the index episode. The sample comprised 3,243 patients (median [IQR] age, 85 [81-90] years; 53% women), with 1,096 (34%) in the ED group and 2,147 (66%) in the ward group. In-hospital mortality for patients spending the night in the ED the ED group was 10.7% and 9.5% for patients transferred to a ward bed before midnight the ward group (adjusted OR: 1.12, 95%CI: 0.80-1.58). Sensitivity analyses rendered similar results (ORs ranged 1.06-1.13). Interaction was only detected for academic/non-academic hospitals (p < 0.001), with increased mortality risk for the latter (1.01, 0.33-3.09 vs 2.86, 1.30-6.28). There were no differences in prolonged hospitalization (> 7days), with adjusted OR of 1.16 (0.94-1.43) and 1.15 (0.94-1.42) depending on whether time spent in the ED was or was not taken into consideration. No increased risk of in-hospital mortality or prolonged hospitalization was found in older patients waiting overnight in the ED for admission. Nonetheless, all estimations suggest a potential harmful effect of staying overnight, especially if a proper bedroom and hospitalist ward bed and hospitalized care are not provided.

Effect of early initiation of noninvasive ventilation in patients transported by emergency medical service for acute heart failure

Background While the indication for noninvasive ventilation (NIV) in severely hypoxemic patients with acute heart failure (AHF) is often indicated and may improve clinical course, the benefit of early initiation before patient arrival to the emergency department (ED) remains unknown. Objective This study aimed to assess the impact of early initiation of NIV during emergency medical service (EMS) transportation on outcomes in patients with AHF. Design A secondary retrospective analysis of the EAHFE (Epidemiology of AHF in EDs) registry. Setting Fifty-three Spanish EDs. Participants Patients with AHF transported by EMS physician-staffed ambulances who were treated with NIV at any time during of their emergency care were included and categorized into two groups based on the place of NIV initiation: prehospital (EMS group) or ED (ED group). Outcome measures Primary outcome was the composite of in-hospital mortality and 30-day postdischarge death, readmission to hospital or return visit to the ED due to AHF. Secondary outcomes included 30-day all-cause mortality after the index event (ED admission) and the different component of the composite primary endpoint considered individually. Multivariate logistic regressions were employed for analysis. Results Out of 2406 patients transported by EMS, 487 received NIV (EMS group: 31%; EMS group: 69%). Mean age was 79 years, 48% were women. The EMS group, characterized by younger age, more coronary artery disease, and less atrial fibrillation, received more prehospital treatments. The adjusted odds ratio (aOR) for composite endpoint was 0.66 (95% CI: 0.42–1.05). The aOR for secondary endpoints were 0.74 (95% CI: 0.38–1.45) for in-hospital mortality, 0.74 (95% CI: 0.40–1.37) for 30-day mortality, 0.70 (95% CI: 0.41–1.21) for 30-day postdischarge ED reconsultation, 0.80 (95% CI: 0.44–1.44) for 30-day postdischarge rehospitalization, and 0.72 (95% CI: 0.25–2.04) for 30-day postdischarge death. Conclusion In this ancillary analysis, prehospital initiation of NIV in patients with AHF was not associated with a significant reduction in short-term outcomes. The large confidence intervals, however, may preclude significant conclusion, and all point estimates consistently pointed toward a potential benefit from early NIV initiation.

Clinical course in older patients diagnosed with syncope treated in Spanish emergency departments: results from the Emergency Department and Elder Needs-17 study.

To study factors associated with hospitalization in an unselected population of patients aged 65 years or older treated for syncope in Spanish hospital emergency departments (EDs). To determine the prevalence of adverse events at 30 days in patients discharged home and the factors associated with such events. We included all patients aged 65 years or older who were diagnosed with syncope during a single week in 52 Spanish EDs, recording patient clinical and ED case management data. We compared the findings between hospitalized patients and those discharged home, following the latter for 30 days. In discharged patients, we explored predictors of a composite adverse-event outcome (occurrence of any of the following: ED revisits, hospitalization related to the index visit, or any-cause death). A total of 477 patients with syncope were identified; 67 (14%) were admitted, and 5 (7.5%) died. The median (interquartile range) length of hospital stay was 6 days (3-11 days). Comorbidity increased the probability of hospitalization (odds ratio, 2.172; 95% CI, 1.013-4.655). Among the 410 patients (86%) discharged home from the ED, 9.2% experienced an adverse event within 30 days (ED revisits, 8.,1%; hospitalization, 2.2%; death, 1.5%). No factors were associated with the 30-day composite outcome. The majority of patients aged 65 years or older are discharged home from EDs, and 30-day adverse events, while infrequent, are difficult to predict. Hospitalization was related to comorbidity and an absence of cognitive decline.

Salmonella Bacteremia in Spanish Pediatric Emergency Departments: Uncommon But Not Mild.

Salmonella spp. is an uncommon microorganism in bloodstream infections among pediatric patients in our setting, although in developing countries it is the most common causative organism in blood cultures. We describe the children presenting to pediatric emergency departments and diagnosed with Salmonella bacteremia (SB) and identify clinical and laboratory predictors of poor outcome (ie, complications, sequelae and death) by bivariate analysis. We performed an observational study and subanalysis of a multicenter prospective registry, including patients <18 years of age with a positive blood culture obtained at any of the 22 participating Spanish pediatric emergency departments between 2011 and 2016. We considered young age, chronic diseases, immunosuppressive treatment and intestinal flora disruption as risk factors for SB. Of the 55 patients with SB (3.2% of registered bacteremia), 32 (58.2%) had no risk factors for SB, 42 (76.3%) had a normal pediatric assessment triangle and 45 (81.8%) an associated gastrointestinal infection (acute gastroenteritis or enteric fever). Nine (16.4%) had a poor outcome, including 1 death (1.8%). A poor outcome was more common in patients with an abnormal pediatric assessment triangle [odds ratio (OR): 51.6; 95% confidence interval (CI): 9.2-289.5], an altered physical examination (OR: 15.2; 95% CI: 4.4-58.8) and elevated C-reactive protein (OR: 1.01; 95% CI: 1.005-1.03). Most SBs were related to a gastrointestinal infection. One in 6 children had a poor outcome; abnormal pediatric assessment triangle on arrival (25% of patients) was the main risk factor identified.

Impact of dementia on 30-, 180-, and 365-day mortality during the first pandemic wave in older adults seen in spanish emergency departments diagnosed with or without COVID-19

Objectives To assess whether dementia is an independent predictor of death after a hospital emergency department (ED) visit by older adults with or without a COVID-19 diagnosis during the first pandemic wave. Method We used data from the EDEN-Covid (Emergency Department and Elderly Needs during Covid) cohort formed by all patients ≥65 years seen in 52 Spanish EDs from March 30 to April 5, 2020. The association of prior history of dementia with mortality at 30, 180 and 365 d was evaluated in the overall sample and according to a COVID-19 or non COVID diagnosis. Results We included 9,770 patients aged 78.7 ± 8.3 years, 51.1% men, 1513 (15.5%) subjects with prior history of dementia and 3055 (31.3%) with COVID-19 diagnosis. 1399 patients (14.3%) died at 30 d, 2008 (20.6%) at 180 days and 2456 (25.1%) at 365 d. The adjusted Hazard Ratio (aHR) for age, sex, comorbidity, disability and diagnosis for death associated with dementia were 1.16 (95% CI 1.01–1.34) at 30 d; 1.15 at 180 d (95% CI 1.03–1.30) and 1.19 at 365 d (95% CI 1.07–1.32), p < .001. In patients with COVID-19, the aHR were 1.26 (95% CI: 1.04–1.52) at 30 days; 1.29 at 180 d (95% CI: 1.09–1.53) and 1.35 at 365 d (95% CI: 1.15–1.58). Conclusion Dementia in older adults attending Spanish EDs during the first pandemic wave was independently associated with 30-, 180- and 365-day mortality. This impact was lower when adjusted for age, sex, comorbidity and disability, and was greater in patients diagnosed with COVID-19.

Epidemiological aspects, clinical management and short-term outcomes in elderly patients diagnosed with acute heart failure in the emergency department in Spain: results of the EDEN-34 study

ObjectiveTo estimate the incidence of acute heart failure (AHF) diagnosis in elderly patients in emergency departments (ED), diagnostic confirmation in hospitalized patients, and short-term adverse events. MethodsAll patients aged ≥65 years attended in 52 Spanish EDs during 1 week were included and those diagnosed with AHF were selected. In hospitalized patients, those diagnosed with AHF at discharge were collected. As adverse events, in-hospital and 30-day mortality, and combined adverse event (death or hospitalization) at 30 days post-discharge were collected. Adjusted odds ratios (OR) for association of demographic variables, baseline status and constants at ED arrival with mortality and 30-day post-discharge adverse event were calculated. ResultsWe included 1,155 patients with AHF (annual incidence: 26.5 per 1000 inhabitants ≥65 years, 95% CI: 25.0–28.1). In 86% the diagnosis of AHF was known at discharge. Overall 30-day mortality was 10.7% and in-hospital mortality was 7.9%, and the combined event in 15.6%. In-hospital and 30-day mortality was associated with arterial hypotension (adjusted OR: 74.0, 95% CI: 5.39–1015. and 42.6, 3.74–485, respectively and hypoxemia (2.14, 1.27–3.61; and 1.87, 1.19–2.93) on arrival at the ED and requiring assistance with ambulation (2.24, 1.04–4.83; and 2.48, 1.27–4.86) and age (per 10-year increment; 1.54, 1.04–2.29; and 1.60, 1.13–2.28). The combined post-discharge adverse event was not associated with any characteristic. ConclusionsAHF is a frequent diagnosis in elderly patients consulting in the ED. The functional impairment, age, hypotension and hypoxemia are the factors most associated with mortality.

Short-term prognosis of polypharmacy in elderly patients treated in emergency departments: results from the EDEN project.

Polypharmacy is a growing phenomenon among elderly individuals. However, there is little information about the frequency of polypharmacy among the elderly population treated in emergency departments (EDs) and its prognostic effect. This study aims to determine the prevalence and short-term prognostic effect of polypharmacy in elderly patients treated in EDs. A retrospective analysis of the Emergency Department Elderly in Needs (EDEN) project's cohort was performed. This registry included all elderly patients who attended 52 Spanish EDs for any condition. Mild and severe polypharmacy was defined as the use of 5-9 drugs and ⩾10 drugs, respectively. The assessed outcomes were ED revisits, hospital readmissions, and mortality 30 days after discharge. Crude and adjusted logistic regression analyses, including the patient's comorbidities, were performed. A total of 25,557 patients were evaluated [mean age: 78 (IQR: 71-84) years]; 10,534 (41.2%) and 5678 (22.2%) patients presented with mild and severe polypharmacy, respectively. In the adjusted analysis, mild polypharmacy and severe polypharmacy were associated with an increase in ED revisits [odds ratio (OR) 1.13 (95% confidence interval (CI): 1.04-1.23) and 1.38 (95% CI: 1.24-1.51)] and hospital readmissions [OR 1.18 (95% CI: 1.04-1.35) and 1.36 (95% CI: 1.16-1.60)], respectively, compared to non-polypharmacy. Mild and severe polypharmacy were not associated with increased 30-day mortality [OR 1.05 (95% CI: 0.89-2.26) and OR 0.89 (95% CI: 0.72-1.12)], respectively. Polypharmacy was common among the elderly treated in EDs and associated with increased risks of ED revisits and hospital readmissions ⩽30 days but not with an increased risk of 30-day mortality. Patients with polypharmacy had a higher risk of ED revisits and hospital readmissions ⩽30 days after discharge.

Impact of First Wave of COVID-19 Pandemic on Mortality at Emergency Department in Older Patients with COVID and Non-COVID Diagnoses

Introduction: Mortality in emergency departments (EDs) is not well known. This study aimed to assess the impact of the first-wave pandemic on deaths accounted in the ED of older patients with COVID and non-COVID diseases. Methods: We used data from the Emergency Department and Elderly Needs (EDEN) cohort (pre-COVID period) and from the EDEN-COVID cohort (COVID period) that included all patients ≥65 years seen in 52 Spanish EDs from April 1 to 7, 2019, and March 30 to April 5, 2020, respectively. We recorded patient characteristics and final destination at ED. We compared older patients in the pre-COVID period, with older patients with non-COVID and with COVID-19. ED-mortality (before discharge or hospitalization) is the prior outcome and is expressed as an adjusted odds ratio (aOR) with 95% interval confidence. Results: We included 23,338 older patients from the pre-COVID period (aged 78.3 [8.1] years), 6,715 patients with non-COVID conditions (aged 78.9 [8.2] years) and 3,055 with COVID (aged 78.3 [8.3] years) from the COVID period. Compared to the older patients, pre-COVID period, patients with non-COVID and with COVID-19 were more often male, referred by a doctor and by ambulance, with more comorbidity and disability, dementia, nursing home, and more risk according to qSOFA, respectively (p < 0.001). Compared to the pre-COVID period, patients with non-COVID and with COVID-19 were more often to be hospitalized from ED (24.8% vs. 44.3% vs. 79.1%) and were more often to die in ED (0.6% vs. 1.2% vs. 2.2%), respectively (p < 0.001). Compared to the pre-COVID period, aOR for age, sex, comorbidity and disability, ED mortality in elderly patients cared in ED during the COVID period was 2.31 (95% confidence interval [CI]: 1.76–3.06), and 3.75 (95% CI: 2.77–5.07) for patients with COVID. By adding the variable qSOFA to the model, such OR were 1.59 (95% CI: 1.11–2.30) and 2.16 (95% CI: 1.47–3.17), respectively. Conclusions: During the early first pandemic wave of COVID-19, more complex and life-threatening older with COVID and non-COVID diseases were seen compared to the pre-COVID period. In addition, the need for hospitalization and the ED mortality doubled in non-COVID and tripled in COVID diagnosis. This increase in ED mortality is not only explained by the complexity or severity of the elderly patients but also because of the system’s overload.

Aspectos epidemiológicos y de manejo clínico relativos a las neumonías diagnosticadas en urgencias en pacientes mayores en España: resultados del estudio EDEN-29

ObjectivesTo estimate the incidence of pneumonia diagnosis in elderly patients in Spanish emergency departments (ED), need for hospitalization, adverse events and predictive capacity of biomarkers commonly used in the ED. MethodsPatients ≥65 years with pneumonia seen in 52 Spanish EDs were included. We recorded in-hospital and 30-day mortality as adverse events, as well as intensive care unit (ICU) admission among hospitalized patients. Association of 10 predefined variables with adverse events was calculated and expressed as odds ratio (OR) with 95% confidence interval (CI), as well as predictive capacity of 5 commonly used biomarkers in the ED (leukocytes, hemoglobin, C-reactive protein, glucose, creatinine) was investigated using area under the receiver operating characteristic curve (AUC-ROC). Results591 patients with pneumonia attended in the ED were included (annual incidence of 18.4 per 1,000 inhabitants). A total of 78% were hospitalized. Overall, 30-day mortality was 14.2% and in-hospital mortality was 12.9%. Functional dependency was associated with both events (OR=4.453, 95%CI=2.361-8.400; and OR=3.497, 95%CI=1.578- 7.750, respectively) as well as severe comorbidity (2.344, 1.363-4.030, and 2.463, 1.252-4.846, respectively). Admission to the ICU during hospitalization occurred in 3.5%, with no associated factors. The predictive capacity of biomarkers was only moderate for creatinine for ICU admission (AUC-ROC=0.702, 95%CI=0.536-0.869) and for leukocytes for post-discharge adverse event (0.669, 0.540-0.798). ConclusionsPneumonia is a frequent diagnosis in elderly patients consulting in the ED. Their functional dependence and comorbidity is the most frequent factor associated with adverse events. The biomarkers analyzed do not have a good predictive ability to predict adverse events.

Influence of type of household on prognosis at one year in patients ≥65years attending hospital emergency departments in Spain. The EDEN-6 study.

To investigate whether the type of household is associated with prognosis at one year in patients ≥65years of age discharged after medical consultation requiring emergency department care. Data from the Emergency Department and Elder Needs (EDEN) cohort were used. This retrospective cohort included all patients ≥65years of age seen in 52 Spanish emergency departments over one week (April 1-7, 2019) in whom the type of household was recorded and categorized as living at home alone, with relatives, with professional caregivers, or in a nursing home. Patient demographic and other baseline characteristics and management during the index emergency department episode were recorded and used to adjust the following 1-year outcomes: all-cause mortality, hospitalization and emergency department revisit. Associations between type of household and outcomes are expressed as adjusted hazard ratios with 95% confidence intervals using living alone as the reference category. 13,442 patients with a median age of 79years (interquartile range 72-86) were included; 56% were women, 12.2% of patients lived alone, 74.9% with relatives, 3.9% with a professional caregiver, and 9.1% in a nursing home. During the year following discharge, the mortality rate was 14.0%, the hospitalization rate 29.7%, and the emergency department revisit rate 59.3%. In the fully adjusted model, the risk of death was associated only with living in a nursing home (hazard ratio 1.366 (1.101-1.695)). On the other hand, the risk of hospitalization was lower in individuals living in nursing homes (hazard ratio 0.783 [0.676-0.907]) and at home with relatives (hazard ratio 0.897 [0.810-0.992]), while the risk of emergency department revisit was lower in individuals living in nursing homes (hazard ratio 0.826 [0.742-0.920]) or at home with caregivers (hazard ratio 0.856 [0.750-0.976]). The type of household was modestly associated with the one-year prognosis of patients ≥65years of age discharged after attendance at an emergency department. Living in a nursing home is associated with an increased risk of death but a decreased risk of rehospitalization or emergency department revisit, while living at home with relatives or professional caregivers is associated only with a decreased risk of hospitalization and emergency department revisit, respectively.

Sex- and age-related patterns in the use of analgesics in older patients in the emergency department.

Treatment of acute pain in older patients is a common challenge faced in emergency departments (EDs). Despite many studies that have investigated chronic analgesic use in the elderly, data on patterns of acute use, especially in EDs, of analgesics according to patient characteristics is scarce. To investigate sex- and age-related patterns of analgesic use in the Spanish EDs and determine differences in age-related patterns according to patient sex. A secondary analysis of the Emergency Department and Elderly Needs (EDEN) multipurpose cohort. Fifty-two Spanish EDs (17% of Spanish EDs covering 25% of Spanish population). All patients' ≥65 years attending ED during 1 week (April 1-7, 2019). Patient characteristics recorded included age, sex, chronic treatment with non-steroidal anti-inflammatory drugs (NSAIDs) and opiates, comorbidity, dependence, dementia, depression, ability to walk and previous falls. Analgesics used in the ED were categorized in three groups: non-NSAID non-opioids (mainly paracetamol and metamizole, PM), NSAIDs, and opiates. Frequency of analgesic use was quantified, and the relationship between sex and age and analgesic use (in general and for each analgesic group) was assessed by unadjusted and adjusted logistic regression and restricted cubic spline models. Interaction between sex and age was explored. We included 24 573 patients, and 6678 (27.2%) received analgesics in the ED: 5551 (22.6%) PM, 1661 (6.8%) NSAIDs and 937 (3.8%) opiates (1312 received combinations). Analgesics were more frequently used in women (adjusted OR = 1.076, 95%CI = 1.014-1.142), as well as with NSAID (1.205, 1.083-1.341). Analgesic use increased with age, increasing PM and decreasing NSAIDs use. Opiate use remained quite constant across age and sex. Interaction of sex with age was present for the use of analgesics in general ( P = 0.006), for PM ( P < 0.001) and for opiates ( P = 0.033), with higher use of all these analgesics in women. Use of analgesics in older individuals in EDs is mildly augmented in women and increases with age, with PM use increasing and NSAIDs decreasing with age. Conversely, opiate use is quite constant according to sex and age. Age-related patterns differ according to sex, with age-related curves of women showing higher probabilities than those of men to receive any analgesic, PM or opiates.

Utilidad predictiva de mortalidad de las escalas qSOFA, NEWS y GYM en el paciente anciano con infección en urgencias: estudio EDEN-5

ObjectiveTo analyze the prognostic accuracy of the scores NEWS, qSOFA, GYM used in hospital emergency department (ED) in the assessment of elderly patients who consult for an infectious disease. MethodsData from the EDEN (Emergency Department and Elderly Needs) cohort were used. This retrospective cohort included all patients aged ≥65years seen in 52 Spanish EDs during two weeks (from 1/4/2019 to 7/4/2019 and 30/3/2020 to 5/4/2020) with an infectious disease diagnosis in the emergency department. Demographic variables, comorbidities, Charlson and Barthel index and needed scores parameters were recorded. The predictive capacity for 30-day mortality of each scale was estimated by calculating the area under the receiver operating characteristic (ROC) curve, and sensitivity and specificity were calculated for different cut-off points. The primary outcome variable was 30-day mortality. ResultsSix thousand fifty-four patients were analyzed. Median age was 80years (IQR 73-87) and 45.3% women. Nine hundred and ninety-three (16.4%) patients died. NEWS score had better AUC than qSOFA (0.765; 95%CI: 0.725-0.806, vs. 0.700; 95%CI: 0.653-0.746; P<.001) and GYM (0.716; 95%CI: 0.675-0.758; P=.024), and there was no difference between qSOFA and GYM (P=.345). The highest sensitivity scores for 30-day mortality were GYM ≥1 point (85.4%) while the qSOFA score ≥2 points showed high specificity. In the case of the NEWS scale, the cut-off point ≥4 showed high sensitivity, while the cut-off point NEWS ≥8 showed high specificity. ConclusionNEWS score showed the highest predictive capacity for 30-day mortality. GYM score ≥1 showed a great sensitivity, while qSOFA ≥2 scores provide the highest specificity but lower sensitivity.

Feasibility of a selective targeted strategy of HIV testing in emergency departments: a before-after study.

The rates of hidden infection and late diagnosis of HIV still remain high in Western countries. Missed diagnostic opportunities represent the key point in changing the course of the epidemic. To evaluate the feasibility and results of implementation of a selective strategy to test for HIV in the emergency department (ED) in patients with six pre-defined medical situations: sexually transmitted infections, herpes zoster, community-acquired pneumonia, mononucleosis syndrome, practice of chemsex (CS) or request of post-exposure prophylaxis. This quasi-experimental longitudinal study evaluated the pre- and post-implementation results of HIV testing in the six aforementioned clinical scenarios. Patients attended 34 Spanish EDs. The intervention was an intensive educational program and pathways to facilitate and track orders and results were designed. We collected and compared pre- and post-implementation ED census and diagnoses, and HIV tests requested and results. The main outcome was adherence to the recommendations. Secondary outcomes were to evaluate the effectiveness of the program by the rate of positive test and the new HIV diagnoses. Differences between first and second periods were assessed. The magnitude of changes (absolute and relative) was expressed with the 95% confidence interval (CI). HIV tests increasing from 7080 (0.42% of ED visits) to 13 436 (relative increase of 75%, 95% CI from 70 to 80%). The six conditions were diagnosed in 15 879 and 16 618 patients, and HIV testing was ordered in 3393 (21%) and 7002 (42%) patients (increase: 97%; 95% CI: 90-104%). HIV testing significantly increased for all conditions except for CS. The positive HIV test rates increased from 0.92 to 1.67%. Detection of persons with undiagnosed HIV increased from 65 to 224, which implied a 220% (95% CI: 143-322%) increase of HIV diagnosis among all ED comers and a 71% (95% CI: 30-125%) increase of positive HIV tests. Implementation of a strategy to test for HIV in selective clinical situations in the ED is feasible and may lead to a substantial increase in HIV testing and diagnoses.
