Assessment of real-time electrocardiogram effects on interpretation quality by emergency physicians.

BACKGROUND: Electrocardiogram (ECG) is one of the most commonly performed examinations in emergency medicine. The literature suggests that one-third of ECG interpretations contain errors and can lead to clinical adverse outcomes. The purpose of this study was to assess the quality of real-time ECG interpretation by senior emergency physicians compared to cardiologists and an ECG expert. METHODS: This was a prospective study in two university emergency departments and one emergency medical service. All ECGs were performed and interpreted over five weeks by a senior emergency physician (EP) and then by a cardiologist using the same questionnaire. In case of mismatch between EP and the cardiologist our expert had the final word. The ratio of agreement between both interpretations and the kappa (k) coefficient characterizing the identification of major abnormalities defined the reading ability of the emergency physicians. RESULTS: A total of 905 ECGs were analyzed, of which 705 (78%) resulted in a similar interpretation between emergency physicians and cardiologists/expert. However, the interpretations of emergency physicians and cardiologists for the identification of major abnormalities coincided in only 66% (k: 0.59 (95% confidence interval (CI): 0.54-0.65); P-value = 1.64e-92). ECGs were correctly classified by emergency physicians according to their emergency level in 82% of cases (k: 0.73 (95% CI: 0.70-0.77); P-value ≈ 0). Emergency physicians correctly recognized normal ECGs (sensitivity = 0.91). CONCLUSION: Our study suggested gaps in the identification of major abnormalities among emergency physicians. The initial and ongoing training of emergency physicians in ECG reading deserves to be improved.

Pain Self-Management with Inhaled Methoxyflurane by Emergency Department Trauma Patients: A Prospective, Interventional, Single-Center Study.

The coronavirus disease 2019 (COVID-19) pandemic has led to overcrowding in many emergency departments (EDs). The present single-center, prospective, interventional study (conducted at Bichat University Medical Center (Paris, France)) was designed to assess the impact of self-administered, inhaled, low-dose methoxyflurane on trauma pain in a pre-ED fast-track zone dedicated to the management of lower-acuity non-COVID-19 patients. In the first phase of the study, the control group consisted of patients with mild-to-moderate trauma pain, for whom the triage nurse initiated pain management (based on the World Health Organization (WHO)'s analgesic ladder). In the second phase, the intervention group consisted of similar patients who self-administered methoxyflurane as an adjuvant to the standard analgesic ladder. The primary endpoint was the numerical pain rating scale (NPRS) score (from 0 to 10) recorded at different time points during the patient's care (T0: arrival in the ED, T1: exit from the triage box, T2: in the radiology department, T3: clinical examination, and T4: discharge from the ED). The level of agreement between the NPRS and the WHO analgesic ladder was assessed by the calculation of Cohen's kappa. Pairwise comparisons of continuous variables were performed with Student's t-test or a non-parametric Mann-Whitney U test. Changes over time in the NPRS were analyzed in an analysis of variance (with Scheffe's post hoc test if a pairwise comparison was significant) or a non-parametric Kruskal-Wallis H test. In all, 268 and 252 patients were included in the control and intervention groups, respectively. The two groups had similar characteristics. The level of agreement between the NPRS score and the analgesic ladder was high in both the control and intervention groups (Cohen's kappa: 0.74 and 0.70, respectively). The NPRS score decreased significantly between T0 and T4 in both groups (p < 0.001), but the decrease between T2 and T4 was significantly greater in the intervention group (p < 0.001). The proportion of patients still in pain on discharge was significantly lower in the intervention group than in the control group (p = 0.001). In conclusion, a combination of self-administered methoxyflurane and the WHO analgesic ladder improves pain management in the ED.

Prognosis of hospitalised adult patients with respiratory syncytial virus infection: a multicentre retrospective cohort study.

OBJECTIVES: Respiratory syncytial virus (RSV) is a common agent of viral respiratory infections with significant morbidity and mortality in adults. The objective of this study was to determine risk factors for mortality and invasive mechanical ventilation and to describe the characteristics of patients who received ribavirin. METHODS: A retrospective multicentre observational cohort study was conducted in Great Paris area hospitals, including patients hospitalised between 1 January 2015 and 31 December 2019 for documented RSV infection. Data were extracted from the Assistance Publique-Hôpitaux de Paris Health Data Warehouse. The primary endpoint was in-hospital mortality. RESULTS: One thousand one hundred sixty-eight patients were hospitalised for RSV infection, including 288 (24.6%) patients who required intensive care unit (ICU) admission. The median (interquartile range) age of patients was 75 (63-85) years, and 54% (n = 631/1168) of them were women. In-hospital mortality was 6.6% (n = 77/1168) in the whole cohort and 12.8% (n = 37/288) in ICU patients. Factors associated with hospital mortality were age >85 years (adjusted odds ratio [aOR] = 6.29, 95% confidence interval [2.47-15.98]), acute respiratory failure (aOR = 2.83 [1.19-6.72]), non-invasive (aOR = 12.60 [1.41-112.36]), and invasive mechanical ventilation support (aOR = 30.13 [3.17-286.27]) and neutropenia (aOR = 13.19 [3.27-53.27]). Factors associated with invasive mechanical ventilation were chronic heart (aOR = 1.98 [1.20-3.26]) or respiratory failure (aOR = 2.83 [1.67-4.80]), and co-infection (aOR = 2.62 [1.60-4.30]). Patients who were treated with ribavirin were significantly younger than others (62 [55-69] vs. 75 [63-86] years; p < 0.001), more frequently males (n = 34/48 [70.8%] vs. n = 503/1120 [44.9%]; p 0.001), and almost exclusively immunocompromised (n = 46/48 [95.8%] vs. n = 299/1120 [26.7%]; p < 0.001). DISCUSSION: The mortality rate of patients hospitalised with RSV infections was 6.6%. Twenty-five per cent of the patients required ICU admission.

Effect of diagnosis level of certainty on adherence to antibiotics' guidelines in ED patients with pneumonia: a post-hoc analysis of an interventional trial.

BACKGROUND AND IMPORTANCE: Clinical diagnosis of community-acquired pneumonia (CAP) is difficult to establish with certainty. Adherence to antibiotic guidelines independently affects the prognosis of CAP patients. OBJECTIVE: We aimed to determine whether guidelines' adherence was related to CAP diagnosis level of certainty and could be reinforced accordingly to diagnosis improvement. DESIGN: Secondary analysis of a prospective, multicenter study, which evaluated the impact of early thoracic CT scan on diagnosis and therapeutic plan in patients with clinically suspected CAP visiting emergency departments. SETTING AND PARTICIPANTS: In total 319 patients with clinically suspected CAP were enrolled in four emergency departments, Paris, France, between Nov 2011 and Jan 2013. OUTCOME MEASURES AND ANALYSIS: We evaluated guidelines' adherence before and after CT scan and its relationship with CAP diagnosis level of certainty. Antibiotics were categorized as adherent according to 2010 French guidelines. CAP diagnosis level of certainty was prospectively classified by the emergency physicians based on a Likert scale as excluded, possible, probable or definite before and immediately after the CT scan. These classifications and therapeutic plans were also completed by an independent adjudication committee. Determinants of adherence were assessed using Poisson regression with robust variance. MAIN RESULTS: Adherence to guidelines increased from 34.2% before CT scan to 51.3% after CT scan [difference 17.1% (95% CI, 9.5-24.7)], meanwhile CAP diagnosis with high level of certainty (definite and excluded CAP) increased from 46.1 to 79.6% [difference 33.5% (95% CI, 26.5-40.5)]. Diagnosis level of certainty before CT scan was the strongest determinant of adherence in multivariate analysis (RR, 2.63; 95% CI, 1.89-3.67). CONCLUSION: Antibiotic guidelines' adherence was poor and positively related to CAP diagnosis level of certainty. The results suggest that improvements in CAP diagnosis may increase adherence to antibiotic guidelines. Clinical trial registered with www.clinicaltrials.gov (NCT01574066).

The Response of Emergency Departments (EDs) to the COVID-19 Pandemic: The Experience of 5 EDs in a Paris-Based Academic Hospital Trust.

The coronavirus disease-2019 (COVID-19) pandemic has imposed unforeseen and unprecedented constraints on emergency departments (EDs). In this study, we detail the organizational and managerial tools recently implemented among 5 academic EDs in a French region particularly affected by COVID-19 and analyze how EDs responded to the COVID-19-related disease burden during different phases of the epidemic. Initially, they focused on the early detection of suspected cases by identifying 3 predominant COVID-19 syndromes. During this diagnostic process, patients were placed in respiratory isolation (facial mask before triage) and droplet isolation (ED rooms). A 3-level strategy for triage, clinical pathways in the EDs, and the organization of hospital spaces was based on the real-time polymerase chain reaction (RT-PCR) COVID-19 positivity rate, with ED strategies adapted to the exigencies of each level. This crisis demonstrated hospitals' adaptability and capacity to mobilize in the face of new risks, with hospitals and EDs coordinating their management to reallocate resources, optimize interoperability, and rethink patient pathways. This report on their processes may assist hospitals and EDs in areas currently spared by the new variants.

The “GHU-Checkist”: Validity and acceptability of a 17-words checklist for rapid screening of depressive symptoms and anxiety

Background and objectives: Early detection of psychiatric disorders in general hospital settings could facilitate a systematic assessment of anxiety and depression, and lessen their non-detection, misdiagnoses and subsequent negative impacts. We built a new short screening tool with simple Yes/No questions on anxiety and depression and examined its diagnostic capacity and acceptability.MethodsOur cross-sectional study included 608 patients examined in an emergency department at a Parisian general hospital. Their depressive and anxiety symptoms were assessed with the Patient Health Questionnaire (PHQ-9), and the Generalized Anxiety Disorder 7 (GAD-7). Participants also completed the ‘GHU-checklist’, a list of 17 words evoking moods or feelings. Sensitivity and specificity of the checklist were determined using receiver operating characteristic (ROC) analysis.Results22.7% of participants had depressive symptoms as measured by the PHQ-9, while 25.4% suffered from moderate or severe anxiety. Most participants perceived positively the GHU-checklist, which had a sensitivity of 81.5% in distinguishing patients with depressive symptoms. Sensitivity was 86.0% for moderate anxiety and 94.7% for severe anxiety. The specificity ranged from 64.3% to 71.1%.ConclusionsA short 17-words checklist is able to ultra-rapidly screen for depressive and anxiety symptoms in non-psychiatric medical settings, and was perceived positively by patients. Its systematic use could facilitate a rapid and systematic assessment of these symptoms, especially in crowded and under-staffed settings such as the emergency department. (AU)

Feasibility of large-scale eOSCES: the simultaneous evaluation of 500 medical students during a mock examination.

The COVID-19 pandemic has led health schools to cancel many on-site training and exams. Teachers were looking for the best option to carry out online OSCEs, and Zoom was the obvious choice since many schools have used it to pursue education purposes. METHODS: We conducted a feasibility study during the 2020-2021 college year divided into six pilot phases and the large-scale eOSCEs on Zoom on June 30th, 2021. We developed a specific application allowing us to mass create Zoom meetings and built an entire organization, including a technical support system (an SOS room and catching-up rooms) and teachers' training sessions. We assessed satisfaction via an online survey. RESULTS: On June 30th, 531/794 fifth-year medical students (67%) participated in a large-scale mock exam distributed in 135 Zoom meeting rooms with the mobilization of 298 teachers who either participated in the Zoom meetings as standardized patients (N =135, 45%) or examiners (N =135, 45%) or as supervisors in the catching-up rooms (N =16, 6%) or the SOS room (N =12, 4%). In addition, 32/270 teachers (12%) experienced difficulties connecting to their Zoom meetings and sought the help of an SOS room member. Furthermore, 40/531 students (7%) were either late to their station or had technical difficulties and declared those issues online and were welcomed in one of the catching-up rooms to perform their eOSCE stations. Additionally, 518/531 students (98%) completed the entire circuit of three stations, and 225/531 students (42%) answered the online survey. Among them, 194/225 (86%) found eOSCES helpful for training and expressed their satisfaction with this experience. CONCLUSION: Organizing large-scale eOSCEs on Zoom is feasible with the appropriate tools. In addition, eOCSEs should be considered complementary to on-site OSCEs and to train medical students in telemedicine.

Early diagnosis of sepsis using an E-health application for a clinical early warning system outside of the intensive care unit: a case report.

BACKGROUND: Elderly and frail patients who are unable to call for help in case of vital distress can develop complications during their hospitalization. As a supplement to clinical monitoring by the nursing staff, these patients can also be monitored in real time, with the Sensium E-health technology. An application notifies clinical staff of any change in their vital signs (heart rate, respiratory rate, temperature) outside of normal ranges, suggestive of physiological decline. Nurses and physicians are notified of these abnormal changes by email and also via mobile application (iPhone or iPad), allowing early intervention to prevent further deterioration. CASE PRESENTATION: An 86-year-old Caucasian female, with chronic kidney disease, was hospitalized in our medical unit for pyelonephritis associated with a moderate deterioration of serum creatinine. Remote continuous monitoring allowed us to diagnose clinical deterioration early and adjust her treatment. The treatment improved her clinical condition and amended the secondary sepsis with circulation failure in 2 days. CONCLUSIONS: The prognosis for patients with acute complicated pyelonephritis is much worse than for those with uncomplicated pyelonephritis. Remote continuous monitoring might be helpful to early diagnose urosepsis. This technology leads to improved prognosis of patients without initial vital distress, allowing early treatment and admission to intensive care unit.

Predictors of Risk Stratification and Value of Point-of-Care of High-Sensitivity Cardiac Troponin-I in EMS Management of Non-ST-Segment Elevation Myocardial Infarction: A Retrospective Study.

INTRODUCTION: The European Society of Cardiology (ESC) 2020 guidelines propose an algorithm for in-hospital management of non-ST-elevation myocardial infarction (NSTEMI) based on risk stratification according to clinical, electrocardiographic, and biological data. However, out-of-hospital management is not codified. STUDY OBJECTIVE: The objective of the present study was to evaluate the role of high-sensitivity cardiac troponin-I in out-of-hospital management of NSTEMI by Emergency Medical Services (EMS). METHODS: This monocentric, retrospective, observational study analyzed the files of all patients having received a troponin assay in the EMS of Beaujon University Hospital, AP-HP (Paris region, France) from January 1, 2020 through December 31, 2020. Patients were classified as low risk, high risk, or very high risk according to the ESC 2020 algorithm at the time of their hospital treatment. The relationship between troponin in point-of-care and risk level according to time to onset of pain was analyzed using logistic regression. A search for predictors of risk level was performed using multivariate analysis. A P value <.05 was considered significant. RESULTS: Out of 309 patients in the file, 233 were included. Men were 61% and the median age was 63 years. A positive troponin assay was associated with high-risk or very high-risk stratification regardless of the time to onset of pain (P <.0001). Predictive factors for being classified as high or very high risk in hospital were: a history of atrial fibrillation (P = .03), electrocardiogram (ECG) modifications such as negative T wave or ST-segment depression (P <.0001), and positive troponin (P <.0001). CONCLUSION: The use of point-of-care troponin in EMS, combined with clinical and electrical criteria, allows risk stratification of NSTEMI patients from the prehospital management stage and optimization of referral to an appropriate care pathway. Patients classified as low risk should be referred to the emergency department (ED) and patients classified as high risk or very high risk to the cardiac intensive care unit or percutaneous coronary intervention (PCI) center.

Assessment of Predictor Factors Associated with Multiple Emergency Department Attendance with Asthma Attack: A Qualitative and Multicentric Prospective Observational Study.

Purpose: Identified factors associated with multiple emergency department (ED) visits (≥) for asthma, which is associated with death. Patients and Methods: We first conducted a qualitative study. We invited French-speaking adults (≥18 years old) with a diagnosis of asthma for more than 6 months. The identified concepts were transcribed into items. A Delphi method allowed for selecting items for a self-reported questionnaire. In an observational multicentric cross-sectional quantitative study, the resulting 20-item questionnaire and 12-item General Health Questionnaire, exploring psychological distress, were administered to adults visiting an ED for asthma exacerbation. Multivariable logistic regression was used to assess factors associated with ED visits. Results: Data saturation was obtained after 8 patient interviews. Patients who came to the ED seemed unfamiliar with their illness or treatments but were concerned by the disease. The questionnaire was administered to 182 patients. On multivariable logistic regression, multiple and systematic ED visits were associated with asthma exacerbation (adjusted odds ratio (aOR) = 6.89, 95% confidence interval [CI]: 2.25-21.09), asthma perceived as a handicap (aOR=3.19, 95% CI: 1.55-6.57) and reported atopy (OR=2.09, 95% CI: 1.03-4.26). High educational level and lack of maintenance inhaled corticosteroids were protective for multiple ED visits. Conclusion: Inadequate medical care is frequent in patients attending the ED for an asthma exacerbation, associated with strong psychological impact. Questioning the reasons for consulting the ED may help quickly identify patients requiring asthma education and improve their referral.

COVID-19 Preparedness Among Emergency Departments: A Cross-Sectional Study in France.

OBJECTIVES: The aim of this study was to evaluate hospital and emergency department (ED) preparedness in France facing the coronavirus disease 2019 (COVID-19) rapid growth epidemic-phase, and to determine the link between preparedness and responsiveness. METHODS: In this cross-sectional study, from March 7 to March 11, 2020, all heads of ED departments in France were contacted to answer an electronic survey, including 23 questions. Quality, Organization, Training, Resources, Management, Interoperability, and Responsiveness were evaluated by calculating scores (10 points). Multivariate analysis of variance was used to compare scores. Spearman's correlation coefficient and multifaceted regression analysis were performed between Responsiveness and dimensions scores. RESULTS: A total of 287 of 636 French EDs were included (45.1%). Calculated scores showed (median): Quality 5.38; Organization 6.4; Training 4.6; Resources 4.13; Management 2.38; Interoperability 4.0; Responsiveness 6.25; seasonal influenza score was 5. Significant differences between scores as a function of hospital and ED main characteristics were found. Furthermore, we found significant correlations (P < 0.01) between Responsiveness and all preparedness dimensions. Organization (adjusted-R2 0.2897), Management (aR2 0.321), and Interoperability (aR2 0.422) were significantly associated with Responsiveness. CONCLUSIONS: Preparedness in all its dimensions is low, indicating vulnerability. Preparedness and responsiveness face a certain and ongoing risk are close linked, and that Organizational, Management, and Interoperability dimensions are main determinants.

Assessment of HIV-postexposure prophylaxis prescription quality after a training programme and assistance in decisions provided by a computer-based decision program: a cross-over study.

BACKGROUND: Among the tools for preventing HIV transmission, post-exposureprophylaxis (PEP) is an effective means after potential HIV exposure. OBJECTIVES: To evaluate aPEP training program and acomputer-baseddecision program (CBDP) using simulated patients in emergency department (ED) on the quality of PEP prescription. METHODS: This cross-overstudy, carried out from 7January2019 to 28June2019, included 20 ED physicians from 10 tertiary referral hospitals. Intervention consisted of two parts: Period Aassessed physicians' compliance with PEP prescription guidelines before and after atraining program, using 400 post-exposuremedical records (200 occupational and 200 non-occupational). Period Bconsisted of arandomized crossover study involving 40 simulated patients, with physicians using or not using aCBDP. Sensitivity, specificity, and accuracy of PEP prescription in accordance with the guidelines were assessed. RESULTS: In period A, alpha Cronbach was less than 0.7 whereas it increased after the training to be >0.7. Sensitivity increased, especially for occupational patients ranging from 51.8%-66.6% to 70.4%-90.1%, whereas specificity increased for non-occupationalpatients ranging from 15.5%-51.9% to 52.1%-75.3%. In period B, sensitivity, specificity, and rate of complete assessments significantly increased (p < 0.0001) after the initiation of CBDP. Rate of PEP prescription significantly decreased (p < 0.001) for all subcategories. CONCLUSION: Significant recommendations-discordantprescriptions, mainly overprescription, occurred for patients visiting ED for PEP. Training improved quality of PEP prescription but the reduction was modest. The availability of CBDP improved quality of PEP prescription and allowed for better data collection and reduction of PEP prescription.

The analysis of the geographical distribution of emergency departments' frequent users: a tool to prioritize public health policies?

BACKGROUND: The individual factors associated to Frequent Users (FUs) in Emergency Departments are well known. However, the characteristics of their geographical distribution and how territorial specificities are associated and intertwined with ED use are limited. Investigating healthcare use and territorial factors would help targeting local health policies. We aim at describing the geographical distribution of ED's FUs within the Paris region. METHODS: We performed a retrospective analysis of all ED visits in the Paris region in 2015. Data were collected from the universal health insurance's claims database. Frequent Users (FUs) were defined as having visited ≥3 times any ED of the region over the period. We assessed the FUs rate in each geographical unit (GU) and assessed correlations between FUs rate and socio-demographics and economic characteristics of GUs. We also performed a multidimensional analysis and a principal component analysis to identify a typology of territories to describe and target the FUs phenomenon. RESULTS: FUs accounted for 278,687 (11.7%) of the 2,382,802 patients who visited the ED, living in 232 GUs. In the region, median FUs rate in each GU was 11.0% [interquartile range: 9.5-12.5]. High FUs rate was correlated to the territorial markers of social deprivation. Three different categories of GU were identified with different profiles of healthcare providers densities. CONCLUSION: FUs rate varies between territories and is correlated to territorial markers of social deprivation. Targeted public policies should focus on disadvantaged territories.

Added value of rapid respiratory syndromic testing at point of care versus central laboratory testing: a controlled clinical trial.

BACKGROUND: Virus-associated respiratory infections are in the spotlight with the emergence of SARS-CoV-2 and the expanding use of multiplex PCR (mPCR). The impact of molecular testing as a point-of-care test (POCT) in the emergency department (ED) is still unclear. OBJECTIVES: To compare the impact of a syndromic test performed in the ED as a POCT and in the central laboratory on length of stay (LOS), antibiotic use and single-room assignment. METHODS: From 19 November 2019 to 9 March 2020, adults with acute respiratory illness seeking care in the ED of a large hospital were enrolled, with mPCR performed with a weekly alternation in the ED as a POCT (week A) or in the central laboratory (week B). RESULTS: 474 patients were analysed: 275 during A weeks and 199 during B weeks. Patient characteristics were similar. The hospital LOS (median 7 days during week A versus 7 days during week B, P = 0.29), the proportion of patients with ED-LOS <1 day (63% versus 60%, P = 0.57) and ED antibiotic prescription (59% versus 58%, P = 0.92) were not significantly different. Patients in the POCT arm were more frequently assigned a single room when having a positive PCR for influenza, respiratory syncytial virus and metapneumovirus [52/70 (74%) versus 19/38 (50%) in the central testing arm, P = 0.012]. CONCLUSIONS: Syndromic testing performed in the ED compared with the central laboratory failed to reduce the LOS or antibiotic consumption in patients with acute respiratory illness, but was associated with an increased single-room assignment among patients in whom a significant respiratory pathogen was detected.

Analysis of the Feasibility of a Vaccination Campaign against Influenza Epidemic and COVID-19 Pandemic in French Emergency Departments: A National Survey.

BACKGROUND: Vaccination is one of the most effective ways to fight the influenza epidemic and the coronavirus disease 2019 (COVID-19) pandemic, which represent a major public issue. The objective was to investigate the adherence of heads of French emergency departments (ED) and nursing departments on a potential vaccination campaign of healthcare workers (HCW) and patients in ED. METHOD: In February 2021, ED and nursing department heads were asked to answer a national survey. It included 24 questions designed to cover some dimensions, including characteristics of the hospital and emergency departments (ED) and questions on vaccination. RESULTS: 414 responses out of 800 questionnaires (51.8%) were collected. Scores out of 10 were, respectively, 7 (6-8) and 8 (6-9) for vaccination against influenza and COVID-19 for HCW and 2 (2-3) and 2 (2-4) for ED patients (H = 989.3; p < 0.0001). Multivariate logistic regression found that the existence of a vaccine program in the hospital and the use of point of care influenza PCR in ED were positively associated with the acceptance of influenza vaccination campaign for HCW (p = 0.003) and patients (p = 0.015). Factors limiting adherence to a vaccination program of HCW and patients were lack of medical staff (p = 0.041 for HCW and p < 0.0001 for patients), overcrowded ED (p < 0.001), and the inability to follow up with patients after the ED visit (p < 0.0001). CONCLUSIONS: There have been many missed opportunities for influenza vaccination, and there is pressure to vaccinate against COVID-19 as soon as possible. Vaccination campaigns in ED could help to improve vaccination coverage. ED staff are more likely to vaccinate HCW than patients. There are factors that support the implementation of such programs, which can be grouped into a culture of diagnosis, control, and prevention of viral infectious diseases within the hospital and ED. On the other hand, there are limiting factors, such as overcrowding and lack of personnel.

Viral epidemiology and SARS-CoV-2 co-infections with other respiratory viruses during the first COVID-19 wave in Paris, France.

OBJECTIVES: Our work assessed the prevalence of co-infections in patients with SARS-CoV-2. METHODS: All patients hospitalized in a Parisian hospital during the first wave of COVID-19 were tested by multiplex PCR if they presented ILI symptoms. RESULTS: A total of 806 patients (21%) were positive for SARS-CoV-2, 755 (20%) were positive for other respiratory viruses. Among the SARS-CoV-2-positive patients, 49 (6%) had viral co-infections. They presented similar age, symptoms, except for fever (P = .013) and headaches (P = .048), than single SARS-CoV-2 infections. CONCLUSIONS: SARS-CoV-2-infected patients presenting viral co-infections had similar clinical characteristics and prognosis than patients solely infected with SARS-CoV-2.

Características de la exposición al VIH y factores predictores del tiempo de acceso a la profilaxis posexposición: estudio observacional prospectivo / Characteristics of human immunodeficiency virus exposure and predictors of time until access to postexposure prophylaxis: a prospective observational study

OBJETIVOS: La eficacia de la profilaxis posexposición al virus de la inmunodeficiencia humana (VIH) depende de un tiempo inferior a 4 horas entre la exposición y la administración del tratamiento. Este estudio evalúa los factores predictores del tiempo entre la exposición al VIH y la llegada a urgencias. MÉTODOS: Estudio observacional, prospectivo, realizado en el Hospital Universitario de Bichat (París, Francia). Se incluyeron todas las consultas en urgencias en 2016 y 2017 por exposición al VIH -ocupacional y no ocupacional-. RESULTADOS: Se incluyeron 1.475 pacientes, de los que 598 completaron una encuesta de seguimiento. El retraso ($4horas) entre la exposición al VIH y la consulta en urgencias se asoció con el tipo de exposición al VIH: trabajadores sanitarios, otras exposiciones y sexuales (p < 0,001). Se encontraron diferencias entre la exposición sexual y otras: conocimiento del circuito de PEP: 65,2% y 46,9% (p < 0,001), uso previo de PEP: 23,9% y 13,1% (p = 0,001), uso de alcohol: 36,2% y 18,5% (p < 0,001), uso de drogas: 34,6% y 8,6% (p < 0,001), y chemsex: 26,1% y 0% (p < 0,001).En la exposición sexual, los siguientes factores predicen el retraso: conocimiento y uso previo del circuito de PEP(p < 0,001) disminuyen el riesgo de retraso > 4 horas, y uso de drogas (p = 0,03) y chemsex (p < 0,001) lo aumentan; en la exposición ocupacional, el conocimiento del programa PEP lo disminuye y el uso de drogas lo aumenta(p < 0,001). CONCLUSIÓN:El retraso en la consulta posexposición al VIH es mayor en la exposición sexual. El conocimiento del programa de PEP y su uso previo determinaban un retraso menor. En la exposición sexual, el consumo de alcohol, drogas y chemsex, implican un retraso mayor, en especial en hombres que tienen relaciones sexuales con hombres

BACKGROUND AND OBJECTIVE: The efficacy of postexposure prophylaxis (PEP) after human immunodeficiency virus (HIV)contact relies on administering the treatment within 4 hours of contact with the virus. This study aimed to evaluate predictors of the time that elapses between HIV exposure and emergency department arrival. METHODS: Prospective observational study carried out at Hôpital Bichat, a university teaching hospital in Paris, France. All emergency visits for occupational or non occupational exposure to HIV in 2016 and 2017 were included. RESULTS: A total of 1475 cases were studied; 598 patients responded to the follow-up survey. A delay of 4 hours or more between HIV exposure and the emergency department visit was associated with type of contact: health care occupational exposure, other occupational exposure, or sexual intercourse (P< .001). We found significant differences between individuals exposed during sexual contact versus occupational exposure with respect to knowledge of the PEP program pathway (65.2%vs 46.9%, respectively), previous use of PEP (23.9%vs 13.1%), alcohol intake (36.2%vs 18.5%), drug use (34.6%vs 8.6%), and chemsex (sexualized drug use) (26.1%vs 0%) (P< .001, all comparisons).Predictors of time until start of PEP among individuals exposed during sexual intercourse were knowledge and prioruse of the PEP pathway (P< .001), drug use (P= .03), and chemsex (P< .001). Predictors among occupationally exposed individuals were prior knowledge of the PEP pathway and drug use (P< .001). CONCLUSIONS: Delay in seeking PEP after HIV exposure is greater among individuals exposed during sexual intercourse. Knowledge of the PEP program and prior use of it are associated with less delay. Exposure during sexual intercourse, alcohol and drug use, and chemsex are associated with longer delays, especially in men who have sex with men
