The emergency department arrival mode and its relations to ED management and 30-day mortality in acute heart failure: an ancillary analysis from the EURODEM study.

BACKGROUND: Acute heart failure patients are often encountered in emergency departments (ED) from 11% to 57% using emergency medical services (EMS). Our aim was to evaluate the association of EMS use with acute heart failure patients' ED management and short-term outcomes. METHODS: This was a sub-analysis of a European EURODEM study. Data on patients presenting with dyspnoea were collected prospectively from European EDs. Patients with ED diagnosis of acute heart failure were categorized into two groups: those using EMS and those self-presenting (non- EMS). The independent association between EMS use and 30-day mortality was evaluated with logistic regression. RESULTS: Of the 500 acute heart failure patients, with information about the arrival mode to the ED, 309 (61.8%) arrived by EMS. These patients were older (median age 80 vs. 75 years, p < 0.001), more often female (56.4% vs. 42.1%, p = 0.002) and had more dementia (18.7% vs. 7.2%, p < 0.001). On admission, EMS patients had more often confusion (14.2% vs. 2.1%, p < 0.001) and higher respiratory rate (24/min vs. 21/min, p = 0.014; respiratory rate > 30/min in 17.1% patients vs. 7.5%, p = 0.005). The only difference in ED management appeared in the use of ventilatory support: 78.3% of EMS patients vs. 67.5% of non- EMS patients received supplementary oxygen (p = 0.007), and non-invasive ventilation was administered to 12.5% of EMS patients vs. 4.2% non- EMS patients (p = 0.002). EMS patients were more often hospitalized (82.4% vs. 65.9%, p < 0.001), had higher in-hospital mortality (8.7% vs. 3.1%, p = 0.014) and 30-day mortality (14.3% vs. 4.9%, p < 0.001). The use of EMS was an independent predictor of 30-day mortality (OR = 2.54, 95% CI 1.11-5.81, p = 0.027). CONCLUSION: Most acute heart failure patients arrive at ED by EMS. These patients suffer from more severe respiratory distress and receive more often ventilatory support. EMS use is an independent predictor of 30-day mortality.

Strabismus outcomes after surgery: the nationwide SOS France study.

PURPOSE: To describe the types of strabismus operated on, the surgical procedures performed, and the 2-year reoperation rate in France. METHODS: Entire population 5-year cross-sectional analysis of a national medico-administrative database in France between January 2013 and December 2017 included all patients who underwent a first strabismus surgery, with a 2-year follow-up. Patient identification was based on the diagnostic codes of the 10th International Classification of Diseases and surgical procedures on the codes of the Common Classification of Medical Acts. A subgroup analysis comparing non-paralytic and paralytic strabismus was performed. RESULTS: Among the 56,654 patients included (women: 50.8%), 26,892 (47.5%) patients were under 10 years old. Overall, 52,711 (93%) were diagnosed with non-paralytic strabismus and 3,943 (7%) with paralytic strabismus. Among the non-paralytics, the most frequent diagnosis was esotropia (21,282, 37.6%), followed by exotropia (14,392, 25.4%) and vertical strabismus (2,017, 3.6%). Among the paralytics, fourth cranial nerve palsy (1,499, 2.6%) was more frequent than sixth cranial nerve palsy (691, 1.2%) and third cranial nerve palsy (431, 0.8%). The 2-year reoperation rate was 7.7% (4,362 patients), the lowest for non-paralytic (7.4%) and the highest for paralytic (11.4%). CONCLUSION: This first French population-based study about strabismus will contribute to the evaluation of practices at a national level and permit comparisons between countries. Although the 2-year reoperation rate was found to be 1 out of 13 patients, it should be interpreted with caution. Long-term follow-up is still warranted due to considerable variability of the type and severity of strabismus as well as surgical practices.

Low-level HIV viremia is associated with low antiretroviral prescription refill rates and social deprivation.

Optimal management of patients experiencing persistent low-level viremia (LLV) remains challenging and poorly understood. This study aimed to assess the association between poor antiretroviral treatment (ARV) adherence and persistent LLV. ADHELOW is a sub-study of the ECHEC cohort comprising HIV-infected adults with virological failure (viral load>50 copies/mL). Patients were recruited in 2013-2015 from 4 French university hospitals. Those with LLV (i.e., ≥2 viral load measurements between 50 and 500 copies/mL) were selected and matched on age and sex to 3 controls with virological suppression. The adherence rate was estimated using pharmacy-delivered prescription refills over one year. Overall, 60 patients were included (15 LLV and 45 controls). Mean age was 50.20 years, M/F sex ratio was 14 and mean EPICES (social deprivation) score was 42.90. In univariable analyses, LLV patients had significantly lower adherence (<80%: 53.30% vs. 6.67%, p < 0.01) and were more likely to have an EPICES score >40.2 (60.00% vs. 24.44%, p < 0.01). In multivariable analysis, these two variables remained significantly associated with LLV (OR 31.49, CI 95% [4.54-218.70]) and OR 11.00 (CI 95% [1.87-218.70], respectively). Poor long-term treatment adherence, estimated by prescription refills, was strongly associated with LLV. This reinforces the message that adherence counseling should be the primary intervention to overcome LLV.

Epidemiology, treatment and outcome of patients with lower respiratory tract infection presenting to emergency departments with dyspnoea (AANZDEM and EuroDEM studies).

OBJECTIVE: Lower respiratory tract infection (LRTI) is a frequent cause of dyspnoea in EDs, and is associated with considerable morbidity and mortality. We described and compared the management of this disease in Europe and Oceania/South-East Asia (SEA) cohorts. METHODS: We conducted a prospective cohort study with three time points in Europe and Oceania/SEA. We included in this manuscript patients presenting to EDs with dyspnoea and a diagnosis of LRTI in ED. We collected comorbidities, chronic medication, clinical signs at arrival, laboratory parameters, ED management and patient outcomes. RESULTS: A total of 1389 patients were included, 773 in Europe and 616 in SEA. The European cohort had more comorbidities including chronic heart failure, obesity, chronic obstructive pulmonary disease and smoking. Levels of inflammatory markers were higher in Europe. There were more patients with inflammatory markers in Europe and more hypercapnia in Oceania/SEA. The use of antibiotics was higher in SEA (72.2% vs 61.8%, P < 0.001) whereas intravenous diuretics, non-invasive and invasive ventilation were higher in Europe. Intensive care unit admission rate was 9.9% in Europe cohort and 3.4% in Oceania/SEA cohort. ED mortality was 1% and overall in-hospital mortality was 8.7% with no differences between regions. CONCLUSIONS: More patients with LRTI in Europe presented with cardio-respiratory comorbidities, they received more adjunct therapies and had a higher intensive care unit admission rate than patients from Oceania/SEA, although mortality was similar between the two cohorts.

Seasonal variations of patients presenting dyspnea to emergency departments in Europe: Results from the EURODEM Study

Background/aim: To describe seasonal variations in epidemiology, management, and short-term outcomes of patients in Europe presenting to an emergency department (ED) with a main complaint of dyspnea. Materials and methods: Anobservational prospective cohort study was performed in 66 European EDs which included consecutive patients presenting to EDs with dyspnea as the main complaint during 3 72-h study periods. Data were collected on demographics, comorbidities, chronic treatment, prehospital treatment, mode of arrival of patient to ED, clinical signs at admission, treatment in the ED, ED diagnosis, discharge from ED, and in-hospital outcome. Results: The study included 2524 patients with a median age of 69 (53­80) years old. Of the patients presented, 991 (39.3%) were in autumn, 849 (33.6%) were in spring, and 48 (27.1%) were in winter. The winter population was significantly older (P < 0.001) and had a lower rate of ambulance arrival to ED (P < 0.001). In the winter period, there was a higher rate for lower respiratory tract infection (35.1%), and patients were more hypertensive, more hypoxic, and more hyper/hypothermic compared to other seasons. The ED mortality was about 1% and, in hospital, mortality for admitted patients was 7.4%. Conclusion: The analytic method and the outcome of this study may help to guide the allocation of ED resources more efficiently and to recommend seasonal ED management protocols based on the seasonal trend of dyspneic patients.

Get with the guidelines: management of chronic obstructive pulmonary disease in emergency departments in Europe and Australasia is sub-optimal.

BACKGROUND: Exacerbations of chronic obstructive pulmonary disease (COPD) are common in emergency departments (ED). Guidelines recommend administration of inhaled bronchodilators, systemic corticosteroids and antibiotics along with non-invasive ventilation (NIV) for patients with respiratory acidosis. AIM: To determine compliance with guideline recommendations for patients treated for COPD in ED in Europe (EUR) and South East Asia/Australasia (SEA) and to compare management and outcomes. METHODS: In each region, an observational prospective cohort study was performed that included patients presenting to ED with the main complaint of dyspnoea during three 72-h periods. This planned sub-study included those with an ED primary discharge diagnosis of COPD. Data were collected on demographics, clinical features, treatment, disposition and in-hospital mortality. We determined overall compliance with guideline recommendations and compared treatments and outcome between regions. RESULTS: A total of 801 patients was included from 122 ED (66 EUR and 46 SEA). Inhaled bronchodilators were administered to 80.3% of patients, systemic corticosteroids to 59.5%, antibiotics to 44 and 60.6% of patients with pH <7.3 received NIV. The proportion administered systemic corticosteroids was higher in SEA (EUR vs SEA for all comparisons; 52 vs 66%, P < 0.001) as was administration of antibiotics (40 vs 49%, P = 0.02). Rates of NIV and mechanical ventilation were similar. Overall in-hospital mortality was 4.2% (SEA 3.9% vs EUR 4.5%, P = 0.77). CONCLUSION: Compliance with guideline recommended treatments, in particular administration of corticosteroids and NIV, was sub-optimal in both regions. Improved compliance has the potential to improve patient outcome.

Treatment and outcome of adult patients with acute asthma in emergency departments in Australasia, South East Asia and Europe: Are guidelines followed? AANZDEM/EuroDEM study.

OBJECTIVE: Asthma exacerbations are common presentations to ED. Key guideline recommendations for management include administration of inhaled bronchodilators, systemic corticosteroids and titrated oxygen therapy. Our aim was to compare management and outcomes between patients treated for asthma in Europe (EUR) and South East Asia/Australasia (SEA) and compliance with international guidelines. METHODS: In each region, prospective, interrupted time series studies were performed including adult (age >18 years) patients presenting to ED with the main complaint of dyspnoea during three 72 h periods. This was a planned sub-study that included those with an ED primary diagnosis of asthma. Data was collected on demographics, clinical features, treatment in ED, diagnosis, disposition and in-hospital outcome. The results of interest were differences in treatment and outcome between EUR and SEA cohorts. RESULTS: Five hundred and eighty-four patients were identified from 112 EDs (66 EUR and 46 SEA). The cohorts had similar demographics and co-morbidity patterns, with 89% of the cohort having a previous diagnosis of asthma. There were no significant differences in treatment between EUR and SEA patients - inhaled beta-agonists were administered in 86% of cases, systemic corticosteroids in 66%, oxygen therapy in 44% and antibiotics in 20%. Two thirds of patients were discharged home from the ED. CONCLUSION: The data suggests that compliance with guideline-recommended therapy in both regions, particularly corticosteroid administration, is sub-optimal. It also suggests over-use of antibiotics.

Factors associated with delay in transfer of patients with ST-segment elevation myocardial infarction from first medical contact to catheterization laboratory: Lessons from CRAC, a French prospective multicentre registry.

BACKGROUND: It is critical to minimize the time between the first medical contact and primary percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction. AIMS: To identify factors associated with a delay of>120min between first medical contact and primary percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction. METHODS: Data were analysed from a regional French registry of patients undergoing coronary angioplasty for ST-segment elevation myocardial infarction<24h after symptom onset. Patients (n=2081) were grouped according to transfer times from first medical contact to primary percutaneous coronary intervention:>120min; or≤120min. Independent predictors of delay were identified by univariate and multivariable analyses. RESULTS: The median transfer time from first medical contact to primary percutaneous coronary intervention was 112min; 892 patients (42.9%) had a transfer time>120min. A delay of>120min was significantly associated with:≥75km distance from interventional cardiology centre at symptom onset (odds ratio 7.9); more than one medical practitioner involved before interventional cardiology centre (odds ratio 4.5); first admission to a hospital without an interventional cardiology centre (odds ratio 2.9); absence of emergency call (odds ratio 1.6); ≥90min between symptom onset and first medical contact (odds ratio 1.3); Killip class at admission>1 (odds ratio 1.8); lateral ischaemia (odds ratio 1.8); diabetes mellitus (odds ratio 1.6); and hypertension (odds ratio 1.3). CONCLUSIONS: In ST-segment elevation myocardial infarction, a transfer time from first medical contact to primary percutaneous coronary intervention of>120min was associated with geographic, systemic and comorbid factors, several of which appear reasonably actionable.

Epidemiology of patients presenting with dyspnea to emergency departments in Europe and the Asia-Pacific region.

OBJECTIVE: The primary objective of this study was to describe the epidemiology and management of dyspneic patients presenting to emergency departments (EDs) in an international patient population. Our secondary objective was to compare the EURODEM and AANZDEM patient populations. PATIENTS AND METHODS: An observational prospective cohort study was carried out in Europe and the Asia-Pacific region. The study included consecutive patients presenting to EDs with dyspnea as the main complaint. Data were collected on demographics, comorbidities, chronic treatment, clinical signs and investigations, treatment in the ED, diagnosis, and disposition from ED. RESULTS: A total of 5569 patients were included in the study. The most common ED diagnoses were lower respiratory tract infection (LRTI) (24.9%), heart failure (HF) (17.3%), chronic obstructive pulmonary disease (COPD) exacerbation (15.8%), and asthma (10.5%) in the overall population. There were more LRTI, HF, and COPD exacerbations in the EURODEM population, whereas asthma was more frequent in the AANZDEM population. ICU admission rates were 5.5%. ED mortality was 0.6%. The overall in-hospital mortality was 5.0%. In-hospital mortality rates were 8.7% for LRTI, 7.6% for HF, and 5.6% for COPD patients. CONCLUSION: Dyspnea as a symptom in the ED has high ward and ICU admission rates. A variety of causes of dyspnea were observed in this study, with chronic diseases accounting for a major proportion.

Age and factors associated with access and time to post-operative adjuvant chemotherapy in colon cancer: a French epidemiological study.

BACKGROUND: Studies have shown the negative prognostic impact of increased time between colectomy and postoperative adjuvant chemotherapy (AC) in colon cancer (CC). Our aim was to investigate the role of age and non-organizational factors on access and time to AC. METHODS: All adult patients undergoing surgery for stage II or III CC in the "Région Centre-Val de Loire" in 2013, were selected. Time to AC and socio-demographic factors were collected. Logistic regression modeling was used to identify factors associated with access to AC, and a multivariate analysis performed to identify factors associated with time to AC. RESULTS: Among 404 stage II or III patients who underwent colectomy, 182 (45%; sex ratio 1.5; mean age 67.6 years; range 32-90) received AC. AC patients were younger than those without AC (67.6 vs. 77.9 years) and the difference was even greater for stage III patients (69.0 vs. 82.4). The median time to AC was 48 days, exceeding 42 days in 60% of cases. Living alone, postoperative morbidities, and emergency colectomy were independently associated with increased time to AC. Age and other factors were not associated with delayed AC. CONCLUSIONS: Emergency colectomy, postoperative morbidities, and living alone are associated with increased time to AC. Organizational measures to reduce the time to AC are therefore unlikely to have an impact. In contrast, age is not associated with increased time to AC, but to access to AC. Reasons for omitting AC in older patients requires further study.

HIV surveillance combining an assay for identification of very recent infection and phylogenetic analyses on dried spots.

BACKGROUND: Transmitted/founder viruses isolated at the early stage of infection are indicators of the variants that are spreading within a population. The French reporting system for new HIV diagnoses is linked to a virological surveillance using dried serum spots. METHODS: We combined an immunoassay for very recent infection (less than 31 days) to a phylogenetic analysis of transmitted/founder viruses and sociodemographic information to analyze the dynamics of the HIV-1 epidemic during a 3-year period. Bayesian coalescent-based methods were used to explore the temporal and spatial dynamics of the identified clusters. RESULTS: Of 17 010 dried serum spots collected, 549 very recent infections were identified for which both env sequences and sociodemographic data were available. Non-B transmitted/founder viruses were found in 196 cases (35.7%), belonging to six subtypes and seven circulating recombinant forms. Forty-three dyads/clusters were identified (range 2-11 cases), including 107 individuals (19.5%), mainly MSM. The largest cluster involved MSM infected by a CRF02_AG variant. Reconstruction of viral migrations across time suggests that Paris was the major hub of dissemination. CONCLUSION: The study shows the feasibility of the surveillance of the HIV epidemic using this methodology. The observation of actively growing spatiotemporal clusters allows identification of specific networks that may be targets for intervention.
