Temporal Trends in the Use of Computed Tomographic Pulmonary Angiography for Suspected Pulmonary Embolism in the Emergency Department : A Retrospective Analysis.

BACKGROUND: Recently, validated clinical decision rules have been developed that avoid unnecessary use of computed tomographic pulmonary angiography (CTPA) in patients with suspected pulmonary embolism (PE) in the emergency department (ED). OBJECTIVE: To measure any resulting change in CTPA use for suspected PE. DESIGN: Retrospective analysis. SETTING: 26 European EDs in 6 countries. PATIENTS: Patients with CTPA performed for suspected PE in the ED during the first 7 days of each odd month between January 2015 and December 2019. MEASUREMENTS: The primary end points were the CTPAs done for suspected PE in the ED and the number of PEs diagnosed in the ED each year adjusted to an annual census of 100 000 ED visits. Temporal trends were estimated using generalized linear mixed regression models. RESULTS: 8970 CTPAs were included (median age, 63 years; 56% female). Statistically significant temporal trends for more frequent use of CTPA (836 per 100 000 ED visits in 2015 vs. 1112 in 2019; P < 0.001), more diagnosed PEs (138 per 100 000 in 2015 vs. 164 in 2019; P = 0.028), a higher proportion of low-risk PEs (annual percent change [APC], 13.8% [95% CI, 2.6% to 30.1%]) with more ambulatory management (APC, 19.3% [CI, 4.1% to 45.1%]), and a lower proportion of intensive care unit admissions (APC, -8.9% [CI, -17.1% to -0.3%]) were observed. LIMITATION: Data were limited to 7 days every 2 months. CONCLUSION: Despite the recent validation of clinical decision rules to limit the use of CTPA, an increase in the CTPA rate along with more diagnosed PEs and especially low-risk PEs were instead observed. PRIMARY FUNDING SOURCE: None specific for this study.

Comparison of Patients Infected With Delta Versus Omicron COVID-19 Variants Presenting to Paris Emergency Departments : A Retrospective Cohort Study.

BACKGROUND: At the end of 2021, the B.1.1.529 SARS-CoV-2 variant (Omicron) wave superseded the B.1.617.2 variant (Delta) wave. OBJECTIVE: To compare baseline characteristics and in-hospital outcomes of patients with SARS-CoV-2 infection with the Delta variant versus the Omicron variant in the emergency department (ED). DESIGN: Retrospective chart reviews. SETTING: 13 adult EDs in academic hospitals in the Paris area from 29 November 2021 to 10 January 2022. PATIENTS: Patients with a positive reverse transcriptase polymerase chain reaction (RT-PCR) test result for SARS-CoV-2 and variant identification. MEASUREMENTS: Main outcome measures were baseline clinical and biological characteristics at ED presentation, intensive care unit (ICU) admission, mechanical ventilation, and in-hospital mortality. RESULTS: A total of 3728 patients had a positive RT-PCR test result for SARS-CoV-2 during the study period; 1716 patients who had a variant determination (818 Delta and 898 Omicron) were included. Median age was 58 years, and 49% were women. Patients infected with the Omicron variant were younger (54 vs. 62 years; difference, 8.0 years [95% CI, 4.6 to 11.4 years]), had a lower rate of obesity (8.0% vs. 12.5%; difference, 4.5 percentage points [CI, 1.5 to 7.5 percentage points]), were more vaccinated (65% vs. 39% for 1 dose and 22% vs. 11% for 3 doses), had a lower rate of dyspnea (26% vs. 50%; difference, 23.6 percentage points [CI, 19.0 to 28.2 percentage points]), and had a higher rate of discharge home from the ED (59% vs. 37%; difference, 21.9 percentage points [-26.5 to -17.1 percentage points]). Compared with Delta, Omicron infection was independently associated with a lower risk for ICU admission (adjusted difference, 11.4 percentage points [CI, 8.4 to 14.4 percentage points]), mechanical ventilation (adjusted difference, 3.6 percentage points [CI, 1.7 to 5.6 percentage points]), and in-hospital mortality (adjusted difference, 4.2 percentage points [CI, 2.0 to 6.5 percentage points]). LIMITATION: Patients with COVID-19 illness and no SARS-CoV-2 variant determination in the ED were excluded. CONCLUSION: Compared with the Delta variant, infection with the Omicron variant in patients in the ED had different clinical and biological patterns and was associated with better in-hospital outcomes, including higher survival. PRIMARY FUNDING SOURCE: None.

Triaging acute pulmonary embolism for home treatment by Hestia or simplified PESI criteria: the HOME-PE randomized trial.

AIMS: The aim of this study is to compare the Hestia rule vs. the simplified Pulmonary Embolism Severity Index (sPESI) for triaging patients with acute pulmonary embolism (PE) for home treatment. METHODS AND RESULTS: Normotensive patients with PE of 26 hospitals from France, Belgium, the Netherlands, and Switzerland were randomized to either triaging with Hestia or sPESI. They were designated for home treatment if the triaging tool was negative and if the physician-in-charge, taking into account the patient's opinion, did not consider that hospitalization was required. The main outcomes were the 30-day composite of recurrent venous thrombo-embolism, major bleeding or all-cause death (non-inferiority analysis with 2.5% absolute risk difference as margin), and the rate of patients discharged home within 24 h after randomization (NCT02811237). From January 2017 through July 2019, 1975 patients were included. In the per-protocol population, the primary outcome occurred in 3.82% (34/891) in the Hestia arm and 3.57% (32/896) in the sPESI arm (P = 0.004 for non-inferiority). In the intention-to-treat population, 38.4% of the Hestia patients (378/984) were treated at home vs. 36.6% (361/986) of the sPESI patients (P = 0.41 for superiority), with a 30-day composite outcome rate of 1.33% (5/375) and 1.11% (4/359), respectively. No recurrent or fatal PE occurred in either home treatment arm. CONCLUSIONS: For triaging PE patients, the strategy based on the Hestia rule and the strategy based on sPESI had similar safety and effectiveness. With either tool complemented by the overruling of the physician-in-charge, more than a third of patients were treated at home with a low incidence of complications.

A national population-based study of patients, bystanders and contextual factors associated with resuscitation in witnessed cardiac arrest: insight from the french RéAC registry.

BACKGROUND: In out-of-hospital cardiac arrest (OHCA), bystander initiated cardiopulmonary resuscitation (CPR) increases the chance of return of spontaneous circulation and survival with a favourable neurological status. Socioeconomic disparities have been highlighted in OHCA field. In areas with the lowest average socioeconomic status, OHCA incidence increased, and bystander CPR decreased. Evaluations were performed on restricted geographical area, and European evaluation is lacking. We aimed to analyse, at a national level, the impact of area-level social deprivation on the initiation of CPR in case of a witnessed OHCA. METHODS: We included all witnessed OHCA cases with age over 18 years from July 2011 to July 2018 form the OHCA French national registry. We excluded OHCA occurred in front of rescue teams or in nursing home, and patients with incomplete address or partial geocoding. We collected data from context, bystander and patient. The area-level social deprivation was estimated by the French version of the European Deprivation Index (in quintile) associated with the place where OHCA occurred. We assessed the associations between Utstein variables and social deprivation level using a mixed-effect logit model with bystander-initiated CPR. RESULTS: We included 23,979 witnessed OHCA of which 12,299 (51%) had a bystander-initiated CPR. More than one third of the OHCA (8,326 (35%)) occurred in an area from the highest quintile of social deprivation. The higher the area-level deprivation, the less the proportion of bystander-initiated CPR (56% in Quintile 1 versus 48% in Quintile 5). The In the multivariable analysis, bystander less often began CPR in areas with the highest deprivation level, compared to those with the lowest deprivation level (OR=0.69, IC95%: 0.63-0.75). CONCLUSIONS: The level of social deprivation of the area where OHCA occurred was associated with bystander-initiated CPR. It decreased in the more deprived areas although these areas also concentrate more younger patients.

Reducing pain by using venous blood gas instead of arterial blood gas (VEINART): a multicentre randomised controlled trial.

INTRODUCTION: Venous sampling for blood gas analysis has been suggested as an alternative to arterial sampling in order to reduce pain. The main objective was to compare pain induced by venous and arterial sampling and to assess whether the type of sampling would affect clinical management or not. METHODS: We performed an open-label randomised multicentre prospective study in four French EDs during a 4-week period. Non-hypoxaemic adults, whose medical management required blood gas analysis, were randomly allocated using a computer-generated randomisation list stratified by centres with an allocation ratio of 1:1 using random blocks to one of the two arms: venous or arterial sampling. The primary outcome was the maximal pain during sampling, using the visual analogue scale. Secondary outcomes pertained to ease of sampling as rated by the nurse drawing the blood, and physician satisfaction regarding usefulness of biochemical data. RESULTS: 113 patients were included: 55 in the arterial and 58 in the venous sampling group. The mean maximal pain was 40.5 mm±24.9 mm and 22.6 mm±20.2 mm in the arterial group and the venous group, respectively, accounting for a mean difference of 17.9 mm (95% CI 9.6 to 26.3) (p<0.0001). Ease of blood sampling was greater in the venous group as compared with the arterial group (p=0.02). The usefulness of the results, evaluated by the prescriber, did not significantly differ (p=0.25). CONCLUSIONS: Venous blood gas is less painful for patients than ABG in non-hypoxaemic patients. Venous blood gas should replace ABG in this setting. TRIAL REGISTRATION NUMBER: NCT03784664.

Longer symptom onset to aspiration time predicts success of needle aspiration in primary spontaneous pneumothorax.

BACKGROUND: Needle aspiration (NA) is recommended as first-line treatment of primary spontaneous pneumothorax (PSP). We aimed to assess NA success and the effect of a longer symptom onset to NA time. METHODS: A discovery phase was retrospectively conducted in the intensive care unit of Louis Mourier Hospital (January 2000 to December 2011) followed by a prospective validation cohort (January 2012 to August 2015). The primary outcome was immediate NA success defined by the absence of need for chest tube insertion within 24 hours of the procedure. RESULTS: In the discovery phase, 130 patients were admitted for PSP and 98 had NA as first-line treatment (75%). The immediate success rate of NA was 34.7% and was higher when it was performed ≥48 hours after symptom onset (57.7% vs 25%; p=0.004). In the prospective cohort, 87 patients were admitted for PSP; 71 (82%) had NA as first-step treatment. The immediate success rate was 40.8%. NA was more successful when it was performed after 48 hours of symptoms' onset (34.5% vs 7.1%; p=0.005). A delay between the first symptom and NA procedure ≥48 hours was associated with a higher success of NA (OR=13.54; 95% CI 1.37 to 133). A smaller pneumothorax estimated by Light's index was associated with NA success (OR=0.95; 95% CI 0.92 to 0.98). To what extent some of these pneumothoraces would have had a spontaneous resolution remains unknown. CONCLUSION: When managing PSP with NA, a longer symptom onset to NA time was associated with NA success. TRIAL REGISTRATION NUMBER: NCT02528734.

Prognosis of cirrhotic patients admitted to Emergency Departments: A multicenter study.

OBJECTIVES: Life threatening complications can occur at any stage of cirrhosis progression. There are few studies on the prognosis of cirrhotic patients managed in an Emergency Department (ED) although management of patients will occur in the ED. The objective of our study was to determine the risk factors for mortality in cirrhotic patients who visited to the ED. METHODS: All cirrhotic patients attending ED in three different university hospitals of Assistance Publique - Hôpitaux de Paris between January 2014 and June 2015 were identified by a retrospective analysis of digital records and included in the study. The primary end-point was 30-day mortality in all cirrhotic patients who visited the ED. RESULTS: A total of 609 ED visits were analyzed among 224 patients: 115 (51%) presented a cirrhosis of alcoholic origin, 43 (19%) were caused by Hepatitis C, 28 (13%) of mixed origin (viral and alcoholic), 17 (8%) were caused by Hepatitis B and 21 (9%) of other origins. Fifty-five (25%) of these patients died within 30 days of their initial presentation to the ED. In multivariate analysis, the age (Odds Ratio: 1.04 [1.01-1.07]), cirrhosis associated with hepatocellular carcinoma (OR: 3.07 [1.37-6.91]), serum creatinine at admission (OR: 1.01 [1.01-1.02]), serum bilirubin at admission (OR: 1.01 [1.01-1.02]) and health impairment (OR: 2.57 [1.28-5.16]) were associated with mortality. CONCLUSIONS: The mortality rate of cirrhotic patients attending an ED was high. The prognosis of cirrhotic patients admitted to the ED depended on the severity of the liver and other organ dysfunction. The presence of a hepatocellular carcinoma on admission was also a risk factor for death.

Specialist Advice Support for Management of Severe Hereditary Angioedema Attacks: A Multicenter Cluster-Randomized Controlled Trial.

STUDY OBJECTIVE: Hereditary angioedema is a rare disease associated with unpredictable, recurrent attacks of potentially life-threatening edema. Management of severe attacks is currently suboptimal because emergency medical teams are often unaware of new specific treatments. The objective of this trial is to test whether a dedicated national telephone care-management strategy would reduce resource use during severe hereditary angioedema attacks. METHODS: We conducted a cluster-randomized multicenter prospective trial of patients with a documented diagnosis of hereditary angioedema (type I, II or FXII hereditary angioedema). Participants were enrolled between March 2013 and June 2014 at 8 participating reference centers. The randomized units were the reference centers (clusters). Patients in the intervention arm were given a national free telephone number to call in the event of a severe attack. Emergency physicians in the SOS-hereditary angiœdema (SOS-HAE) call center were trained to advise or prescribe specific treatments. The primary outcome was number of admissions for angioedema attacks. Economic evaluation was also performed. RESULTS: We included 100 patients in the SOS-HAE group and 100 in the control group. During the 2 years, there were 2,368 hereditary angioedema attacks among 169 patients (85%). Mean number of hospital admissions per patient in the 2-year period was significantly greater in the usual-practice group (mean 0.16 [range 0 to 2] versus 0.03 [range 0 to 1]); patient risk difference was significant: -0.13 (95% confidence interval -0.22 to -0.04; P=.02). Probabilistic sensitivity graphic analysis indicated a trend toward increased quality-adjusted life-years in the SOS-HAE group. CONCLUSION: A national dedicated call center for management of severe hereditary angioedema attacks is associated with a decrease in hospital admissions and may be cost-effective if facilities and staff are available to deliver the intervention alongside existing services.

Effect of Bag-Mask Ventilation vs Endotracheal Intubation During Cardiopulmonary Resuscitation on Neurological Outcome After Out-of-Hospital Cardiorespiratory Arrest: A Randomized Clinical Trial.

Importance: Bag-mask ventilation (BMV) is a less complex technique than endotracheal intubation (ETI) for airway management during the advanced cardiac life support phase of cardiopulmonary resuscitation of patients with out-of-hospital cardiorespiratory arrest. It has been reported as superior in terms of survival. Objectives: To assess noninferiority of BMV vs ETI for advanced airway management with regard to survival with favorable neurological function at day 28. Design, Settings, and Participants: Multicenter randomized clinical trial comparing BMV with ETI in 2043 patients with out-of-hospital cardiorespiratory arrest in France and Belgium. Enrollment occurred from March 9, 2015, to January 2, 2017, and follow-up ended January 26, 2017. Intervention: Participants were randomized to initial airway management with BMV (n = 1020) or ETI (n = 1023). Main Outcomes and Measures: The primary outcome was favorable neurological outcome at 28 days defined as cerebral performance category 1 or 2. A noninferiority margin of 1% was chosen. Secondary end points included rate of survival to hospital admission, rate of survival at day 28, rate of return of spontaneous circulation, and ETI and BMV difficulty or failure. Results: Among 2043 patients who were randomized (mean age, 64.7 years; 665 women [32%]), 2040 (99.8%) completed the trial. In the intention-to-treat population, favorable functional survival at day 28 was 44 of 1018 patients (4.3%) in the BMV group and 43 of 1022 patients (4.2%) in the ETI group (difference, 0.11% [1-sided 97.5% CI, -1.64% to infinity]; P for noninferiority = .11). Survival to hospital admission (294/1018 [28.9%] in the BMV group vs 333/1022 [32.6%] in the ETI group; difference, -3.7% [95% CI, -7.7% to 0.3%]) and global survival at day 28 (55/1018 [5.4%] in the BMV group vs 54/1022 [5.3%] in the ETI group; difference, 0.1% [95% CI, -1.8% to 2.1%]) were not significantly different. Complications included difficult airway management (186/1027 [18.1%] in the BMV group vs 134/996 [13.4%] in the ETI group; difference, 4.7% [95% CI, 1.5% to 7.9%]; P = .004), failure (69/1028 [6.7%] in the BMV group vs 21/996 [2.1%] in the ETI group; difference, 4.6% [95% CI, 2.8% to 6.4%]; P < .001), and regurgitation of gastric content (156/1027 [15.2%] in the BMV group vs 75/999 [7.5%] in the ETI group; difference, 7.7% [95% CI, 4.9% to 10.4%]; P < .001). Conclusions and Relevance: Among patients with out-of-hospital cardiorespiratory arrest, the use of BMV compared with ETI failed to demonstrate noninferiority or inferiority for survival with favorable 28-day neurological function, an inconclusive result. A determination of equivalence or superiority between these techniques requires further research. Trial Registration: clinicaltrials.gov Identifier: NCT02327026.

Effect of Systematic Intensive Care Unit Triage on Long-term Mortality Among Critically Ill Elderly Patients in France: A Randomized Clinical Trial.

Importance: The high mortality rate in critically ill elderly patients has led to questioning of the beneficial effect of intensive care unit (ICU) admission and to a variable ICU use among this population. Objective: To determine whether a recommendation for systematic ICU admission in critically ill elderly patients reduces 6-month mortality compared with usual practice. Design, Setting, and Participants: Multicenter, cluster-randomized clinical trial of 3037 critically ill patients aged 75 years or older, free of cancer, with preserved functional status (Index of Independence in Activities of Daily Living ≥4) and nutritional status (absence of cachexia) who arrived at the emergency department of one of 24 hospitals in France between January 2012 and April 2015 and were followed up until November 2015. Interventions: Centers were randomly assigned either to use a program to promote systematic ICU admission of patients (n=1519 participants) or to follow standard practice (n=1518 participants). Main Outcomes and Measures: The primary outcome was death at 6 months. Secondary outcomes included ICU admission rate, in-hospital death, functional status, and quality of life (12-Item Short Form Health Survey, ranging from 0 to 100, with higher score representing better self-reported health) at 6 months. Results: One patient withdrew consent, leaving 3036 patients included in the trial (median age, 85 [interquartile range, 81-89] years; 1361 [45%] men). Patients in the systematic strategy group had an increased risk of death at 6 months (45% vs 39%; relative risk [RR], 1.16; 95% CI, 1.07-1.26) despite an increased ICU admission rate (61% vs 34%; RR, 1.80; 95% CI, 1.66-1.95). After adjustments for baseline characteristics, patients in the systematic strategy group were more likely to be admitted to an ICU (RR, 1.68; 95% CI, 1.54-1.82) and had a higher risk of in-hospital death (RR, 1.18; 95% CI, 1.03-1.33) but had no significant increase in risk of death at 6 months (RR, 1.05; 95% CI, 0.96-1.14). Functional status and physical quality of life at 6 months were not significantly different between groups. Conclusions and Relevance: Among critically ill elderly patients in France, a program to promote systematic ICU admission increased ICU use but did not reduce 6-month mortality. Additional research is needed to understand the decision to admit elderly patients to the ICU. Trial Registration: clinicaltrials.gov Identifier: NCT01508819.

Factors associated with hospital admission in hereditary angioedema attacks: a multicenter prospective study.

BACKGROUND: Acute attacks of hereditary angioedema are characterized by recurrent localized edema. These attacks can be life threatening and are associated with substantial morbidity and mortality. OBJECTIVE: To determine factors associated with hospital admission of patients with an acute attack of hereditary angioedema presenting at the emergency department. METHODS: This was a multicenter prospective observational study of consecutive patients (January 2011 through December 2013) experiencing an acute hereditary angioedema attack and presenting at the emergency department at 1 of 4 French reference centers for bradykinin-mediated angioedema. Attacks requiring hospital admission were compared with those not requiring admission. RESULTS: Of 57 attacks in 29 patients, 17 (30%) led to hospital admission. In multivariate analysis, laryngeal and facial involvements were associated with hospital admission (odds ratio 18.6, 95% confidence interval 3.9-88; odds ratio 7.7, 95% confidence interval 1.4-43.4, respectively). Self-injection of icatibant at home was associated with non-admission (odds ratio 0.06, 95% confidence interval 0.01-0.61). The course was favorable in all 57 cases. No upper airway management was required. CONCLUSION: Most patients attended the emergency department because they were running out of medication and did not know that emergency treatment could be self-administered. Risk factors associated with hospital admission were laryngeal and facial involvement, whereas self-injection of icatibant was associated with a return home.

Bradykinin-mediated angioedema: factors prompting ED visits.

OBJECTIVE: Bradykinin-mediated angioedema (AE) is characterized by periodic subcutaneous or submucosal swelling, with the absence of urticaria and itching. It affects the face and extremities. Attacks of abdominal pain and obstruction of the upper airways are the hallmarks of disease severity. The aim of this study was to determine the factors prompting patients to turn up at the hospital emergency department (ED) in the event of an attack. METHODS: This was a retrospective review of attacks experienced by all patients with bradykinin-mediated AE (hereditary, acquired, or drug-induced) who visited our ED between January 2002 and March 2011. Characteristics of attacks prompting ED visits and attacks when patients stayed at home were compared using logistic regression with generalized estimating equations to take into account the correlation between multiple attacks from the same patient. RESULTS: A total of 55 patients were included, of whom 39 had hereditary AE; 13, drug-induced AE; and 3, acquired C1 inhibitor deficiency. The median follow-up was 32 months (interquartile range, 10-99 months). The attack was severe in 324 (58%) of 559 cases. Thirty-two patients (58%) visited the ED for a total of 75 attacks. First attack and laryngeal edema were significantly associated with more frequent ED visits (odds ratio, 5.28 [95% confidence interval, 2.42-11.5] and 4.83 [1.54-15.5], respectively]. C1 inhibitor concentrate and icatibant treatment was significantly more often administered in the ED than at home (odds ratio, 4.9 [2.43-9.88] and 8.25 [2.4-28.3], respectively). CONCLUSIONS: First attack of bradykinin AE and swelling of the larynx were significantly associated with visits to the ED.

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.

Acquired C1-inhibitor deficiency: 7 patients treated with rituximab.

BACKGROUND: Acquired C1-inhibitor deficiency can occur secondary to excessive C1-inhibitor consumption (type I) and be associated with a lymphoid hemopathy, or linked to the presence of anti-C1-inhibitor autoantibodies (type II) in a context of an isolated monoclonal gammopathy, sometimes associated with lymphoproliferation. Efficacy of danazol, tranexamic acid and/or corticosteroids is inconstant. Rituximab efficacy against type II angioedema has been reported. METHODS: Description of 7 rituximab-treated patients, 6 with type II acquired angioedema and 1 with type I. RESULTS: Clinical efficacy (only for type II) was complete for 3, partial for 2 and 2 were therapeutic failures. Only 2 patients had improved biological parameters, with normalization of their C1-inhibitor levels and diminished anti-C1-inhibitor autoantibodies, observed 1-9 months after the last infusion of the second rituximab cycle. An associated lymphoproliferation did not affect the response to treatment. CONCLUSION: Rituximab efficacy in the treatment of acquired angioedema is inconstant and might require repeated cycles.

Erythromycin infusion or gastric lavage for upper gastrointestinal bleeding: a multicenter randomized controlled trial.

STUDY OBJECTIVE: The quality of endoscopy depends on the quality of upper gastrointestinal tract preparation. We determine whether in acute upper gastrointestinal bleeding the frequency of satisfactory stomach visualization was different after intravenous erythromycin, a nasogastric tube with gastric lavage, or both. METHODS: We performed a prospective, randomized, multicenter (6 emergency departments) study in patients with acute upper gastrointestinal bleeding presenting with hematemesis or melena. The patients were randomized into 3 groups: (1) intravenous erythromycin infusion without nasogastric tube placement (erythromycin group), (2) nasogastric tube placement without erythromycin (nasogastric group), and (3) intravenous erythromycin infusion combined with nasogastric tube placement (nasogastric-erythromycin group). The main outcome measure was the proportion of satisfactory stomach visualization. RESULTS: Two hundred fifty-three patients (181 men, mean age 61 years [SD 15 years], 84 with cirrhosis) were randomized: 84 (erythromycin group), 85 (nasogastric group), and 84 (nasogastric-erythromycin group). Overall, there was 85% satisfactory stomach visualization; between-group differences were not significant: -4% (95% confidence interval [CI] -15% to 6%) for the erythromycin group and nasogastric-erythromycin group, 2% (95% CI -14% to 9%) for the erythromycin group and nasogastric group, and -6.5% (95% CI -17% to 4%) for the nasogastric group and nasogastric-erythromycin group. The duration of the endoscopic procedure, rebleeding frequency, the need for a second endoscopy, the number of transfused blood units, and mortality at days 2, 7, and 30 did not differ significantly between groups. CONCLUSION: In acute upper gastrointestinal bleeding, administration of intravenous erythromycin provides satisfactory endoscopic conditions, without the need for a nasogastric tube and gastric lavage.

Efficacy of emergency medical center use of a protocol during telephone calls to give medical advice related to fever or gastroenteritis: a cluster randomized controlled trial. / Eficacia de un protocolo de asesoramiento médico telefónico formalizado para consultas por fiebre o gastroenteritis en centros de comunicación médica de emergencia. Ensayo clínico AMTF.

OBJECTIVES: To determine the efficacy of emergency medical center physicians' use of a protocol to guide their management of telephone consultations for fever and gastroenteritis. MATERIAL AND METHODS: Cluster randomized controlled trial. Participating centers were randomized to use the telephone protocol or provide usual telephone assistance. Six emergency centers in France included calls from patients needing advice on fever or gastroenteritis. Centers assigned to the protocol followed specific guidelines on managing the call and giving advice on treatment. Primary endpoints were the number of in-person visits and hospital admissions required within 15 days of the call. Secondary endpoints were patient satisfaction and costs. RESULTS: A total of 2498 calls were included. Use of the assigned protocol while attending 1234 calls was associated with a relative risk for hospitalization or an unscheduled in-person visit for care of 0.70 (95% CI, 0.58-0.85) versus usual practice. Ambulance use, admission to an intensive care unit, mortality, morbidity, and symptom improvement did not differ significantly between centers using the protocol and those following usual practice. Ninety percent of the patients were satisfied. The cost of care was €91 in centers applying the protocol and €150 in the other centers (P .01). CONCLUSION: Use of the protocol was associated with fewer unscheduled in-person visits for care and fewer hospital admissions. The protocol is safe and less costly than the centers' usual approaches to giving telephone advice.

OBJETIVO: Determinar la eficacia de un protocolo de asesoramiento médico telefónico formalizado (AMTF), realizado por un médico para consultas, para fiebre o gastroenteritis en centros de comunicación médica de emergencia. METODO: Ensayo clínico por conglomerado, controlado. Los pacientes fueron aleatorizados al grupo AMTF o al grupo de atención habitual. Participaron 6 centros de comunicación médica de emergencia franceses. Se incluyeron pacientes que solicitaban asistencia telefónica por fiebre o gastroenteritis. El grupo ATMF realizó recomendaciones protocolizadas sobre el manejo terapéutico. Se valoró el número de consultas presenciales o ingreso hospitalario durante los 15 días siguientes a la consulta. También se evaluó la satisfacción del paciente y el coste económico. RESULTADOS: Se incluyeron 2.498 llamadas. El grupo ATMF (n = 1.234) tuvo un riesgo relativo de 0,70 (CI 95% 0,58 a 0,85) de requerir un ingreso hospitalario o de realizar una consulta no programada durante el seguimiento. No hubo diferencias entre los dos grupos en cuanto al uso de ambulancia, el ingreso en cuidados intensivos, la mortalidad o morbilidad y la mejoría de los síntomas. La satisfacción de los pacientes fue del 90%. El coste total fue de 91 euros en el grupo de la ATMF y de 150 euros en el grupo de atención habitual (p 0,01). CONCLUSIONES: El grupo ATMF se asoció con una disminución de las consultas presenciales no programadas o del ingreso en el hospital. Este procedimiento es seguro y comporta un menor coste que la atención que se realiza habitualmente en la actualidad.

Professional practice assessment for minor head injury management in emergency department and clinical impact of a simulation-based training: Interventional study (before/after).

BACKGROUND: Minor head injury is a frequent reason for consultation in the emergency department. The use of computed tomography (CT) has increased dramatically in patients' care. Good time management implementation and interpretation are required. To study the level of agreement with recommendations for a minor head injury in emergency department management and the impacts of simulation-based training (SBT) on professional practice changes. METHODS: Evaluation of professional practice for patient care in an emergency department according to the recommendations of the French Emergency Medicine Society (SFMU) established in 2012 before and after an SBT, including theoretical and simulation courses. It was based on the analysis of time to carry out a CT scan. It was also based on analysis of adherence to brain and spine scan indications and to hospitalization criteria. RESULTS: The SBT carried out in the evaluation of the professional practices makes it possible to acquire the notion of urgency to obtain the CT Scan within one hour when the criteria are met (p=0.007). Rater reliability for agreement with the hospitalization recommendations was better after SBT (p=0.03, increased Kappa from 0.73 to 0.93). On the other hand, there appeared to be a lack of essential information in the medical file, such as time of onset of head trauma. CONCLUSION: Management of this type of patient appeared to be satisfactory. It can be improved by SBT on the basis of the SFMU 2012 consensus conference. There is a need to improve the software used by the emergency departments, which should include the time of trauma and recommendations. The association of the clinic and the biomarkers could help to limit the indications of the CT scan, and thus to have it organized more rapidly.
