Misdiagnosis of thrombotic microangiopathy in the emergency department: a multicenter retrospective study.

To estimate the rate of inappropriate diagnosis in patients who visited the ED with thrombotic microangiopathy (TMA) and to assess the factors and outcomes associated with emergency department (ED) misdiagnosis. Retrospective multicenter study of adult patients admitted to the intensive care unit (ICU) for TMA from 2012 to 2021 who had previously attended the ED for a reason related to TMA. Patient characteristics and outcomes were compared in a univariate analysis based on whether a TMA diagnosis was mentioned in the ED or not. Forty patients were included. The diagnosis of TMA was not mentioned in the ED in 16 patients (40%). Patients for whom the diagnosis was mentioned in the ED had more frequently a request for schistocytes research, and therefore had more often objectified schistocytes. They also had more frequently a troponin dosage in the ED (even if the difference was not significant), an ECG performed or interpreted, and were admitted more quickly in the ICU (0 [0-0] vs 2 [0-2] days; P = 0.002). Hemoglobin levels decreased significantly in both groups, and creatinine levels increased significantly in the misdiagnosis group between ED arrival and ICU admission. In patients with a final diagnosis of TTP, the time to platelets durable recovery was shorter for those in whom the diagnosis was mentioned in the ED without reaching statistical significance (7 [5-11] vs 14 [5-21] days; P = 0.3).

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.

Cancer Patients' Prehospital Emergency Care: Post Hoc Analysis from the French Prospective Multicenter Study EPICANCER.

BACKGROUND: Very little data are available concerning the prehospital emergency care of cancer patients. The objective of this study is to report the trajectories and outcomes of cancer patients attended by prehospital emergency services. METHODS: This was an ancillary study from a three-day cross-sectional prospective multicenter study in France. Adult patients with cancer were included if they called the emergency medical dispatch center Service d'Aide Médicale Urgente (SAMU). The study was registered on ClinicalTrials.gov (NCT03393260, accessed on 8th January 2018). RESULTS: During the study period, 1081 cancer patients called the SAMU. The three most frequent reasons were dyspnea (20.2%), neurological disorder (15.4%), and fatigue (13.1%). Among those patients, 949 (87.8%) were directed to the hospital, among which 802 (90.8%) were directed to an emergency department (ED) and 44 (5%) were transported directly to an intensive care unit (ICU). A mobile intensive care unit (MICU) was dispatched 213 (31.6%) times. The decision to dispatch an MICU seemed generally based on the patient's reason for seeking emergency care and the presence of severity signs rather than on the malignancy or the patient general health status. Among the patients who were directed to the ED, 98 (16.1%) were deceased on day 30. Mortality was 15.4% for those patients directed to the ED but who were not admitted to the ICU in the next 7 days, 28.2% for those who were admitted to ICU in the next 7 days, and 56.1% for those patients transported by the MICU directly to the ICU. CONCLUSION: Cancer patients attending prehospital emergency care were most often directed to EDs. Patients who were directly transported to the ICU had a high mortality rate, raising the question of improving triage policies.

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

Emergency Department influenza vaccination campaign allows increasing influenza vaccination coverage without disrupting time interval quality indicators.

To evaluate the impact of an influenza vaccination (IV) coverage (IVC) in a vaccination campaign of an Emergency Department (EDVC) and its impact on ED time interval quality indicators. We conducted a 4 year observational study, with an intervention during the 4th year. IVC was calculated during pre-and early-epidemic periods. During the final period, a 12 weeks EDVC was implemented. Physicians and nurses were trained and sensitized in the importance of vaccination, and their role in the prevention of severe forms of influenza was reinforced. The vaccine was proposed by physicians and nurses, and delivered by them. Repeated measures ANOVA is a validated method for related not independent groups ( https://statistics.laerd.com/statistical-guides/repeated-measures-anova-statistical-guide.php ). Overall, IVC was 987/3191 (30.9%) with an increasing trend from 28.8 to 33.2%. In the fourth period, out of 868 patients identified with IV indication, 288 had already been vaccinated (IVC 33.2%). After excluding patients presenting criteria of exclusion, IV was proposed to 475 patients: 317 (66.7%) accepted. The vaccination rate after patient's acceptance was 89.6% (288/317). At the end of the EDVC, influenza vaccination coverage was 572 (284 + 288)/868 (65.9%). The delay between arrival at the ED and seeing the triage nurse and physician as well as the overall ED length of stay were not modified during the study period and before and during EDVC. EDVC effectively doubled the influenza vaccination coverage, without modifying ED time interval quality indicators.

Patient's behaviors and missed opportunities for vaccination against seasonal epidemic influenza and evaluation of their impact on patient's influenza vaccine uptake.

OBJECTIVES: Influenza vaccination (IV) coverage remains low in France. Objectives were to assess patient knowledge and behaviors and missed opportunities for vaccination (MO) and their impact on vaccine uptake. METHODS: This is a prospective-observational study, including emergency department patients at risk for severe influenza. Patients were interviewed about their knowledge and behaviors. We evaluated the health-care voucher scheme (HCVS) and MO. RESULTS: 868 patients were included. Vaccine uptake was 33.2%, 42% of patients knew about the possible severity of influenza, 23% thought that they were not at risk for severe influenza, 39% knew that they have an indication for the vaccine, and 4.3% to 11.5% expressed reservations concerning IV side effects and effectiveness. HCVS was used by 44.3% of patients, but only 14.8% had been vaccinated. MO were reported by 484 patients (69.4%) declaring 1104 consultations and 148 IV propositions (86.6%). Predictors of vaccine uptake (p<0.0001) were: knowledge of serious and fatal influenza forms [OR 0.36 (CI95% 0.25-0.5)]; confidence in influenza vaccine effectiveness [0.38 (0.2-0.7)]; opposition to vaccines [0.22 (0.1-0.48)]; visit to general practitioner [4.53 (2.9-7.1)]; general practitioner proposed IV [2.1 (1.2-3.4)]. CONCLUSION: Our results indicate that high rate of missed opportunities, some patient behaviors and general practitioner visits may explain low influenza vaccine uptake, and that HCVS use is a complex process. Of interest, we found that the patient's knowledge of the potential severity of influenza is not sufficient to promote vaccine, suggesting that the information strategy must be adapted to each patient behavior.

Influenza virus infections among patients attending emergency department according to main reason to presenting to ED: A 3-year prospective observational study during seasonal epidemic periods.

OBJECTIVE: The role of influenza virus in patients presenting at ED during seasonal-epidemic periods has not previously been specified. Our objective was to determine its frequency according to clinical presentation. METHODS: This is a prospective observational study conducted during three-consecutive seasonal Influenza epidemics (2013-2015), including patients presenting i) community-acquired pneumonia (CAP); ii) severe acute symptoms (SAS): respiratory failure (RF), hemodynamic failure (HF), cardiac failure (CF), and miscellaneous symptoms (M); iii) symptoms suggesting influenza (PSSI). Patients were tested for influenza using specific PCR on naso-pharyngeal swabs. RESULTS: Of 1,239 patients, virological samples were taken from 784 (63.3%), 213 (27.2%) of whom were positive for the influenza virus: CAP 52/177 (29.4%), SAS 115/447 (25.7%) and PSSI 46/160 (28.8%) (p = 0.6). In the SAS group positivity rates were: RF 76/263 (28.9%), HF 5/29 (17.2%), CF 15/68 (22.1%), and M 19/87 (21.8%) (p = 0.3). Among the major diagnostic categories, the influenza virus positivity rates were: asthma 60/231 (26%), acute exacerbation of chronic obstructive pulmonary disease 18/86 (20.9%), HIV 5/21 (23.8%) and cardiac failure 33/131 (25.2%). The positivity of the samples has not been associated (p>0.1) nor the presence of signs of severity or admission rate in medical ward nor intensive care unit. CONCLUSIONS: Our results indicate that during seasonal influenza epidemics, Influenza virus-positivity rate is similar in patients attending ED for influenza-compatible clinical features, patients with acute symptoms including pneumonia, respiratory, hemodynamic and cardiac distress, and patients presenting for acute decompensation of chronic respiratory and cardiac diseases.

Unscheduled-return-visits after an emergency department (ED) attendance and clinical link between both visits in patients aged 75 years and over: a prospective observational study.

BACKGROUND: Predictors of unscheduled return visits (URV), best time-frame to evaluate URV rate and clinical relationship between both visits have not yet been determined for the elderly following an ED visit. METHODS: We conducted a prospective-observational study including 11,521 patients aged ≥75-years and discharged from ED (5,368 patients (53.5%)) or hospitalized after ED visit (6,153 patients). Logistic Regression and time-to-failure analyses including Cox proportional model were performed. RESULTS: Mean time to URV was 17 days; 72-hour, 30-day and 90-day URV rates were 1.8%, 6.1% and 10% respectively. Multivariate analysis indicates that care-pathway and final disposition decisions were significantly associated with a 30-day URV. Thus, we evaluated predictors of 30-day URV rates among non-admitted and hospitalized patient groups. By using the Cox model we found that, for non-admitted patients, triage acuity and diagnostic category and, for hospitalized patients, that visit time (day, night) and diagnostic categories were significant predictors (p<0.001). For URV, we found that 25% were due to closely related-clinical conditions. Time lapses between both visits constituted the strongest predictor of closely related-clinical conditions. CONCLUSION: Our study shows that a decision of non-admission in emergency departments is linked with an accrued risk of URV, and that some diagnostic categories are also related for non-admitted and hospitalized subjects alike. Our study also demonstrates that the best time frame to evaluate the URV rate after an ED visit is 30 days, because this is the time period during which most URVs and cases with close clinical relationships between two visits are concentrated. Our results suggest that URV can be used as an indicator or quality.

Predictive factors for longer length of stay in an emergency department: a prospective multicentre study evaluating the impact of age, patient's clinical acuity and complexity, and care pathways.

BACKGROUND: It has been reported that emergency department length of stay (ED-LOS) for older patients is longer than average. Our objective was to determine the effect of age, patient's clinical acuity and complexity, and care pathways on ED-LOS and ED plus observation unit (EDOU) LOS (EDOU-LOS). METHODS: This was a prospective, multicentre, observational study including all patients attending in 2011. Age groups were: I, <50; II, ≥50-64; III, ≥65-74; IV, ≥75-84; V, ≥85 years. Univariate and multivariate analyses were performed. RESULTS: Of 125 478 attendances, 20 845(16.6%) were of patients aged ≥65 years. Multivariate analysis found significant predictors for ED-LOS (C-statistics 0.79, p<0.0000001) to be: arrival mode (ambulance, OR 1.13 (95% CI 1.08 to 1.18)); acuity level (level 4, OR 1.24 (95% CI 1.21 to 1.28); level 1-3, OR 1.54 (95% CI 1.5 to 1.59)); haematological examinations (OR 3.34 (95% CI 3.15 to 3.56)); intravenous treatment (OR 1.58 (95% CI 1.47 to 1.69)); monitoring of vital signs (OR 1.89 (95% CI 1.69 to 2.10)); x-ray examinations (OR 1.53 (95% CI 1.45 to 1.61)); CT/MRI/ultrasound (OR 2.60 (95% CI 2.39 to 2.82)); and specialist advice (OR 1.39 (95% CI 1.30 to 1.48)). For EDOU-LOS (C-statistics 0.81, p<0.0000001) we found: age group (II, OR 1.19 (95% CI 1.16 to 1.22); III, OR 1.42 (95% CI 1.38 to 1.46); IV, OR 1.69 (95% CI 1.65 to 1.74); V, 2.01 (95% CI 1.96 to 2.07)); acuity level (level 4, OR 1.31 (95% CI 1.27 to 1.35); level 1-3, OR 1.71 (95% CI 1.66 to 1.77)); haematological examinations (OR 7.81 (95% CI 7.23 to 8.43)); intravenous treatment (OR 1.95 (95% CI 1.8 to 2.12)); x-ray examinations (OR 1.95 (95% CI 1.85 to 2.06)); CT/MRI/ultrasound (OR 6.74 (95% CI 5.98 to 7.6)); specialist advice (OR 2.24 (95% CI 2.07 to 2.42)); admission to a medical or surgical ward (OR 0.61 (95% CI 0.54 to 0.68)); and transfer (OR 1.79 (95% CI 1.54 to 2.07)). CONCLUSIONS: Whereas ED-LOS and EDOU-LOS seem to be directly related to patients' acuity and complexity, notably the need for diagnostic and therapeutic interventions, only EDOU-LOS was significantly associated with age and proposed care pathways. We propose that EDOU-LOS measurement should be made in EDs with an OU.
