RESUMO
BACKGROUND AND AIMS: Home treatment is considered safe in acute pulmonary embolism (PE) patients selected by a validated triage tool (e.g. simplified PE severity index score or Hestia rule), but there is uncertainty regarding the applicability in underrepresented subgroups. The aim was to evaluate the safety of home treatment by performing an individual patient-level data meta-analysis. METHODS: Ten prospective cohort studies or randomized controlled trials were identified in a systematic search, totalling 2694 PE patients treated at home (discharged within 24â h) and identified by a predefined triage tool. The 14- and 30-day incidences of all-cause mortality and adverse events (combined endpoint of recurrent venous thromboembolism, major bleeding, and/or all-cause mortality) were evaluated. The relative risk (RR) for 14- and 30-day mortalities and adverse events is calculated in subgroups using a random effects model. RESULTS: The 14- and 30-day mortalities were 0.11% [95% confidence interval (CI) 0.0-0.24, I2 = 0) and 0.30% (95% CI 0.09-0.51, I2 = 0). The 14- and 30-day incidences of adverse events were 0.56% (95% CI 0.28-0.84, I2 = 0) and 1.2% (95% CI 0.79-1.6, I2 = 0). Cancer was associated with increased 30-day mortality [RR 4.9; 95% prediction interval (PI) 2.7-9.1; I2 = 0]. Pre-existing cardiopulmonary disease, abnormal troponin, and abnormal (N-terminal pro-)B-type natriuretic peptide [(NT-pro)BNP] at presentation were associated with an increased incidence of 14-day adverse events [RR 3.5 (95% PI 1.5-7.9, I2 = 0), 2.5 (95% PI 1.3-4.9, I2 = 0), and 3.9 (95% PI 1.6-9.8, I2 = 0), respectively], but not mortality. At 30 days, cancer, abnormal troponin, and abnormal (NT-pro)BNP were associated with an increased incidence of adverse events [RR 2.7 (95% PI 1.4-5.2, I2 = 0), 2.9 (95% PI 1.5-5.7, I2 = 0), and 3.3 (95% PI 1.6-7.1, I2 = 0), respectively]. CONCLUSIONS: The incidence of adverse events in home-treated PE patients, selected by a validated triage tool, was very low. Patients with cancer had a three- to five-fold higher incidence of adverse events and death. Patients with increased troponin or (NT-pro)BNP had a three-fold higher risk of adverse events, driven by recurrent venous thromboembolism and bleeding.

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.

OBJECTIVE: The COVID-19 pandemic had a profound negative impact on the psychological wellbeing of healthcare providers (HPs), but little is known about the factors that positively predict mental health of primary care staff during these dire situations. METHODS: We conducted an online questionnaire survey among 702 emergency department workers across 10 hospitals in Switzerland and Belgium following the first COVID-19 wave in 2020, to explore their psychological vulnerability, perceived concerns, self-reported impact and level of pandemic workplace preparedness. Participants included physicians, nurses, psychologists and nondirect care employees (administrative staff). We tested for predictors of psychological vulnerability through both an exploratory cross-correlation with rigorous correction for multiple comparisons and model-based path modelling. RESULTS: Findings showed that the self-reported impact of COVID-19 at work, concerns about contracting COVID-19 at work, and a lack of personal protective equipment were strong positive predictors of Depression, Anxiety, and Stress, and low Resilience. Instead, knowledge of the degree of preparedness of the hospital/department, especially in the presence of a predetermined contingency plan for an epidemic and training sessions about protective measures, showed the opposite effect, and were associated with lower psychological vulnerability. All effects were confirmed after accounting for confounding factors related to gender, age, geographical location and the role played by HPs in the hospital/department. CONCLUSIONS: Difficult working conditions during the pandemic had a major impact on the psychological wellbeing of emergency department HPs, but this effect might have been lessened if they had been informed about adequate measures for minimizing the risk of exposure.

Medical students and professional healthcare providers often underestimate patients' pain, together with decreased neural responses to pain information in the anterior insula (AI), a brain region implicated in self-pain processing and negative affect. However, the functional significance and specificity of these neural changes remains debated. Across two experiments, we recruited university medical students and emergency nurses to test the role of healthcare experience on the brain reactivity to other's pain, emotions, and beliefs, using both pictorial and verbal cues. Brain responses to self-pain was also assessed and compared with those to observed pain. Our results confirmed that healthcare experience decreased the activity in AI in response to others' suffering. This effect was independent from stimulus modality (pictures or texts), but specific for pain, as it did not generalize to inferences about other mental or affective states. Furthermore, representational similarity and multivariate pattern analysis revealed that healthcare experience impacted specifically a component of the neural representation of others' pain that is shared with that of first-hand nociception, and related more to AI than to other pain-responsive regions. Taken together, our study suggests a decreased propensity to appraise others' suffering as one's own, associated with a reduced recruitment of pain-specific information in AI. These findings provide new insights into neural mechanisms leading to pain underestimation by caregivers in clinical settings.

OBJECTIVE: Research suggests that therapeutic communication could enhance patient comfort during medical procedures. Few studies have been conducted in clinical settings, with adequate blinding. Our hypothesis was that a positive message could lead to analgesia and anxiolysis, and that this effect would be enhanced by an empathetic interaction with the nurse performing the procedure, compared with an audio-taped message. This study aimed to modulate the contents and delivery vector of a message regarding peripheral intravenous catheter (PIC) placement in the emergency department (ED). METHODS: This study was a 2 + 2 randomized controlled trial registered on ClinicalTrials.gov (NCT03502655). A positive versus standard message was delivered through audio tape (double-blind) in the first phase ( N = 131) and through the nurse placing the catheter (single-blind) in the second phase ( N = 120). RESULTS: By design, low practitioner empathic behavior was observed in the first phase (median, 1 of 5 points). In the second phase, higher empathic behavior was observed in the positive than in the standard message (median, 2 versus 3, p < .001). Contrary to our hypothesis, the intervention did not affect pain or anxiety reports due to PIC placement in either phase (all p values > .2). CONCLUSIONS: The positive communication intervention did not impact pain or anxiety reports after PIC. There might have been a floor effect, with low PIC pain ratings in a context of moderate pain due to the presenting condition. Hence, such a therapeutic communication intervention might not be sufficient to modulate a mild procedural pain in the ED.

STUDY OBJECTIVE: We aimed to assess the analgesic and anxiolytic efficacy of distraction, a nonpharmacologic intervention provided by 3-dimensional (3D) virtual reality (VR) compared with that provided by 2-dimensional (2D) VR during minor emergency department (ED) procedures. METHODS: This randomized controlled study conducted in the ED of a teaching hospital included patients aged more than or equal to 18 years undergoing minor procedures. The patients watched the same computer-generated VR world either in 3D in a head-mounted display (intervention) or in 2D on a laptop screen (control). Our main outcomes were pain and anxiety during the procedure, assessed on a 100-mm visual analog scale. Secondary outcomes included the impression of telepresence in the computer-generated world assessed using the Igroup Presence Questionnaire, and the prevalence and intensity of cybersickness measured on a 100-mm visual analog scale. RESULTS: The final analysis included 117 patients. The differences in median procedural pain and anxiety levels between the 2D and 3D VR groups were not significant: -3 mm (95% confidence interval [CI] -14 to 8) and -4 mm (95% CI -15 to 3), respectively; the difference in telepresence was 2.0 point (95% CI 0 to 2.0), and the proportion difference of cybersickness was -4% (95% CI -22 to 14), with an intensity difference of -5 mm (95% CI -9 to 3). CONCLUSION: During minor procedures in adult patients in the ED, distraction by viewing a 3D virtual world in a head-mounted VR display did not result in lower average levels of procedural pain and anxiety than that by 2D viewing on a screen despite a higher sense of telepresence. There were no significant differences in the prevalence and intensity of cybersickness between the 2 groups.

BACKGROUND: After mild COVID-19, some outpatients experience persistent symptoms. However, data are scarce and prospective studies are urgently needed. OBJECTIVES: To characterize the post-COVID-19 syndrome after mild COVID-19 and identify predictors. PARTICIPANTS: Outpatients with symptoms suggestive of COVID-19 with (1) PCR-confirmed COVID-19 (COVID-positive) or (2) SARS-CoV-2 negative PCR (COVID-negative). DESIGN: Monocentric cohort study with prospective phone interview between more than 3 months to 10 months after initial visit to the emergency department and outpatient clinics. MAIN MEASURES: Data of the initial visits were extracted from the electronic medical file. Predefined persistent symptoms were assessed through a structured phone interview. Associations between long-term symptoms and PCR results, as well as predictors of persistent symptoms among COVID-positive, were evaluated by multivariate logistic regression adjusted for age, gender, smoking, comorbidities, and timing of the survey. KEY RESULTS: The study population consisted of 418 COVID-positive and 89 COVID-negative patients, mostly young adults (median age of 41 versus 36 years in COVID-positive and COVID-negative, respectively; p = 0.020) and healthcare workers (67% versus 82%; p = 0.006). Median time between the initial visit and the phone survey was 150 days in COVID-positive and 242 days in COVID-negative patients. Persistent symptoms were reported by 223 (53%) COVID-positive and 33 (37%) COVID-negative patients (p = 0.006) and proportions were stable among the periods of the phone interviews. Overall, 21% COVID-positive and 15% COVID-negative patients (p = 0.182) attended care for this purpose. Four surveyed symptoms were independently associated with COVID-19: fatigue (adjusted odds ratio 2.14, 95% CI 1.04-4.41), smell/taste disorder (26.5, 3.46-202), dyspnea (2.81, 1.10-7.16), and memory impairment (5.71, 1.53-21.3). Among COVID-positive, female gender (1.67, 1.09-2.56) and overweight/obesity (1.67, 1.10-2.56) were predictors of persistent symptoms. CONCLUSIONS: More than half of COVID-positive outpatients report persistent symptoms up to 10 months after a mild disease. Only 4 of 14 symptoms were associated with COVID-19 status. The symptoms and predictors of the post-COVID-19 syndrome need further characterization as this condition places a significant burden on society.

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.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic has led to surges of patients presenting to emergency departments (EDs) and potentially overwhelming health systems. OBJECTIVE: We sought to assess the predictive accuracy of host biomarkers at clinical presentation to the ED for adverse outcome. METHODS: Prospective observational study of PCR-confirmed COVID-19 patients in the ED of a Swiss hospital. Concentrations of inflammatory and endothelial dysfunction biomarkers were determined at clinical presentation. We evaluated the accuracy of clinical signs and these biomarkers in predicting 30-day intubation/mortality, and oxygen requirement by calculating the area under the receiver-operating characteristic curve and by classification and regression tree analysis. RESULTS: Of 76 included patients with COVID-19, 24 were outpatients or hospitalized without oxygen requirement, 35 hospitalized with oxygen requirement, and 17 intubated/died. We found that soluble triggering receptor expressed on myeloid cells had the best prognostic accuracy for 30-day intubation/mortality (area under the receiver-operating characteristic curve, 0.86; 95% CI, 0.77-0.95) and IL-6 measured at presentation to the ED had the best accuracy for 30-day oxygen requirement (area under the receiver-operating characteristic curve, 0.84; 95% CI, 0.74-0.94). An algorithm based on respiratory rate and sTREM-1 predicted 30-day intubation/mortality with 94% sensitivity and 0.1 negative likelihood ratio. An IL-6-based algorithm had 98% sensitivity and 0.04 negative likelihood ratio for 30-day oxygen requirement. CONCLUSIONS: sTREM-1 and IL-6 concentrations in COVID-19 in the ED have good predictive accuracy for intubation/mortality and oxygen requirement. sTREM-1- and IL-6-based algorithms are highly sensitive to identify patients with adverse outcome and could serve as early triage tools.

In June 2021, the Swiss parliament accepted a legislative proposal calling for the introduction of a fee to fight emergency department (ED) overcrowding. Although this issue remains a major challenge for health policies, the introduction of such a fee raises many questions, notably regarding health equity. However, other more equitable solutions exist: improving the case management of ED frequent users and improving coordination between ED and primary care.
En juin 2021, le Parlement fédéral a accepté une proposition législative demandant l'instauration d'une taxe aux urgences pour lutter contre leur surfréquentation. Bien que cette problématique demeure un enjeu majeur des politiques de santé, l'instauration d'une telle taxe pose de nombreuses questions, notamment d'équité en santé. Pourtant, d'autres solutions existent, en améliorant la prise en charge des usager-ère-s fréquent-e-s des urgences, ainsi que la coordination entre soins primaires et services d'urgences.

BACKGROUND: Lung ultrasonography (LUS) is a promising pragmatic risk-stratification tool in coronavirus disease 2019 (COVID-19). This study describes and compares LUS characteristics between patients with different clinical outcomes. METHODS: Prospective observational study of polymerase chain reaction-confirmed adults with COVID-19 with symptoms of lower respiratory tract infection in the emergency department (ED) of Lausanne University Hospital. A trained physician recorded LUS images using a standardized protocol. Two experts reviewed images blinded to patient outcome. We describe and compare early LUS findings (≤24 hours of ED presentation) between patient groups based on their 7-day outcome (1) outpatients, (2) hospitalized, and (3) intubated/dead. Normalized LUS score was used to discriminate between groups. RESULTS: Between 6 March and 3 April 2020, we included 80 patients (17 outpatients, 42 hospitalized, and 21 intubated/dead). Seventy-three patients (91%) had abnormal LUS (70% outpatients, 95% hospitalized, and 100% intubated/dead; Pâ =â .003). The proportion of involved zones was lower in outpatients compared with other groups (median [IQR], 30% [0-40%], 44% [31-70%], 70% [50-88%]; Pâ <â .001). Predominant abnormal patterns were bilateral and there was multifocal spread thickening of the pleura with pleural line irregularities (70%), confluent B lines (60%), and pathologic B lines (50%). Posterior inferior zones were more often affected. Median normalized LUS score had a good level of discrimination between outpatients and others with area under the ROC of .80 (95% CI, .68-.92). CONCLUSIONS: Systematic LUS has potential as a reliable, cheap, and easy-to-use triage tool for the early risk stratification in patients with COVID-19 presenting to EDs.

OBJECTIVE: Frequent users of emergency departments (FUED) account for a disproportionate number of emergency department (ED) visits and contribute to a wide range of challenges for ED staff. While several research has documented that case management (CM) tailored to FUED leads to a reduction in ED visits and a better quality of life (QoL) among FUED, whether there is added value for ED staff remains to be explored. This study aimed to compare, among staff in two academic EDs in Switzerland (one with and one without CM), the FUED-related knowledge, perceptions of the extent of the FUED issue, FUED-related work challenges and FUEDs' legitimacy to use ED. METHOD: Mixed methods were employed. First, ED physicians and nurses (N = 253) of the two EDs completed an online survey assessing their knowledge and perceptions of FUEDs. Results between healthcare providers working in an ED with CM to those working in an ED without CM were compared using independent two-sided T-tests. Next, a sample of participants (n = 16) took part in a qualitative assessment via one-to-one interviews (n = 6) or focus groups (n = 10). RESULTS: Both quantitative and qualitative results documented that the FUED-related knowledge, the extent FUED were perceived as an issue and perceived FUEDs' legitimacy to use ED were not different between groups. The level of perceived FUED-related challenges was also similar between groups. Quantitative results showed that nurses with CM experienced more challenges related to FUED. Qualitative exploration revealed that lack of psychiatric staff within the emergency team and lack of communication between ED staff and CM team were some of the explanations behind these counterintuitive findings. CONCLUSION: Despite promising results on FUEDs' QoL and frequency of ED visits, these preliminary findings suggest that CM may provide limited support to ED staff in its current form. Given the high burden of FUED-related challenges encountered by ED staff, improved communication and FUED-related knowledge transfer between ED staff and the CM team should be prioritized to increase the value of a FUED CM intervention for ED staff.

BACKGROUND: Frequent users of emergency departments (FUEDs) (≥5 ED visits/year) represent a vulnerable population with complex needs accounting for a significant number of emergency department (ED) consultations, thus contributing to EDs overcrowding. Research exploring ED staff perceptions of FUEDs is scarce. OBJECTIVES: The current study aimed to evaluate in ED staff a) the extent to which FUEDs are perceived as an issue; b) their perceived levels of knowledge and understanding of FUEDs; c) levels of perceived usefulness of case management (CM) and interest in implementing this intervention in their ED service. METHODS: Head physicians of the EDs at all public hospitals in Switzerland (of various level of specialization) were sent a 19-item web-based survey, pilot tested prior to its dissemination. The head physicians were asked to forward the survey to ED staff members from different health professional backgrounds. RESULTS: The hospital response rate was 81% (85/106). The exploitable hospital response rate was 71% (75/106 hospitals) including 208 responding health professionals. Issues and difficulties around FUEDs were perceived as important by 64% of respondents. The perceived frequency of being confronted with FUEDs was higher among nurses in more specialized EDs. In total, 64% of respondents felt poorly informed about FUEDs, nurses feeling less informed than physicians. The understanding of FUEDs was lower in the French-Italian-speaking parts (FISP) of Switzerland than in the German-speaking part. Eighty-one percent of respondents had no precise knowledge of FUED-related interventions. The perceived usefulness of CM interventions after receiving explanations about it was high (92%). However, the overall level of interest for CM implementation was 59%. The interest in CM by physicians was low across all regions and ED categories. Nurses, on the other hand, showed more interest, especially those in EDs of high specialization. CONCLUSIONS: The majority of ED staff reported being confronted with FUEDs on a regular basis. Staff perceived FUEDs as a vulnerable population, yet, they felt poorly informed about how to manage the issue. The majority of ED staff thought a CM intervention would be useful for FUEDs, however there appears to be a gap in their desire or willingness to implement such interventions.

OBJECTIVES: To determine the prevalence of pulmonary embolism (PE) and alternative diagnoses detected by computed tomography pulmonary angiography (CTPA) in pregnant women; and to assess changes over time regarding radiation dose, technical quality, and examination frequency. MATERIALS AND METHODS: This retrospective study included all pregnant women referred for CTPA due to clinically suspected PE over 17 years. Two blinded radiologists reviewed the CTPAs in consensus with regard to PE, alternative diagnoses, and technical quality. We retrieved patient data regarding radiation dose metrics and associated clinical and laboratory parameters. Subgroup comparisons were performed (Wilcoxon and Kruskal-Wallis tests). RESULTS: Of the 237 identified patients, 8 (3.3%) were excluded due to inadequate technical CTPA quality, and 229 patients were analyzed (mean age, 31.7 years; mean gestational age, 28 ± 7 weeks). The four different CT systems used over the study period had similar technical quality (p = 0.28). Of 229 patients 16 (7%) patients had PE, 144 (62.9%) had no abnormal findings, and 69 (30.1%) had an alternative diagnosis (consolidation, other pulmonary opacities, pleural effusion, and basal atelectasis). Gestational age, symptoms, and D-dimer levels were not significantly different between patients with or without PE (p > 0.05). Over time, radiation dose exposure decreased by 30% (p < 0.001), while the number of annual examinations increased by > 4-folds. CONCLUSIONS: In pregnant women, CTPA rarely indicates PE and more often shows alternative diagnoses. Over 17 years, the use of CTPA in pregnancy has notably increased, while the radiation dose exposure has decreased by one third. KEY POINTS: ⢠The use of CTPA in pregnancy has steadily risen over the last 17 years ⢠In pregnant women, CTPA rarely reveals PE and more often shows alternative diagnoses ⢠Recent technical improvements have substantially decreased the radiation dose exposure inherent in CTPA without reducing diagnostic image quality.

INTRODUCTION: Although ketamine use in emergency medicine is widespread, studies investigating prehospital use are scarce. Our goal was to assess the self-reported modalities of ketamine use, knowledge of contraindications, and occurrence of adverse events associated with its use by physicians through a prospective online survey. METHODS: The survey was administered to physicians working for Air-Glaciers, a Swiss alpine helicopter-based emergency service, and was available between September 24 and November 23, 2018. We enrolled 39 participants (participation rate of 87%) in our study and collected data regarding their characteristics, methods of ketamine use, knowledge of contraindications, and encountered side effects linked to the administration of ketamine. We also included a clinical scenario to investigate an analgesic strategy. RESULTS: Ketamine was considered safe and judged irreplaceable by most physicians. The main reason for ketamine use was acute analgesia during painful procedures, such as manipulation of femur fractures. The doses of ketamine administered with or without fentanyl ranged from 0.2 to 0.7 mg·kg-1 intravenously. Most physicians reported using fentanyl and midazolam along with ketamine. The median dose of midazolam was 2 (interquartile range 1-2) mg for a 70-kg adult. Monitoring and oxygen administration were used infrequently. Hallucinations were the most common adverse events. Knowledge of ketamine contraindications was poor. CONCLUSIONS: Ketamine use was reported by mountain rescue physicians to be safe and useful for acute analgesia. Most physicians use fentanyl and midazolam along with ketamine. Adverse neuropsychiatric events were rare. Knowledge regarding contraindications to the administration of ketamine should be improved.

OBJECTIVE: Transient loss of consciousness (TLOC) is a common presentation in the emergency room, where patient history can usually differentiate syncope from generalized tonic-clonic (GTC) seizures. Several serum markers, such as creatine kinase and lactate, can be helpful, especially when history is unreliable. Here, we explore a potential supporting role of electrolyte plasma levels in a case-control study. METHODS: In our electroencephalographic database, we retrospectively identified consecutive episodes of loss of consciousness in adults seen over 3 years in our hospital emergency department for a case-control study. We investigated plasma levels of several electrolytes (sodium, potassium, phosphate, calcium, magnesium) at the emergency visit, as well as demographics, diagnosis, blood-sample delay time, and history of alcohol abuse. RESULTS: Of the 126 patients identified, 75 had GTC seizures and 46 had other TLOC causes. Among electrolyte levels, only hypophosphatemia was associated with GTC seizures (median = 0.79 mmol·L-1 , range = 0.34-1.37 in GTC seizures vs 0.93 mmol·L-1 , range = 0.52-1.56, P = 0.001 in TLOC). After adjusting for blood sampling delay, alcohol abuse, and other electrolyte levels, only hypophosphatemia was associated with GTC seizures, occurring in 37 (51%) of GTC seizures and 12 (22%) of other TLOC (odds ratio = 3.5, 95% confidence interval = 1.5-8.3, P = 0.003). Hypophosphatemia < 0.6 mmol·L-1 was 93% specific and 20% sensitive for GTC seizure occurrence. In follow-ups, hypophosphatemia was transitory. SIGNIFICANCE: Transient hypophosphatemia is common after GTC seizures and could represent an additional biological marker to help differentiate GTC seizures from other TLOC, especially when history is unclear. This hypothesis needs to be tested prospectively.

BACKGROUND: Hip fracture causes moderate to severe pain and while fascia iliaca block has been reported to provide analgesic benefit, most previous trials were unblinded, with subsequent high risks of performance, selection and detection biases. In this randomized, control double-blind trial, we tested the hypothesis that a fascia iliaca block provides effective analgesia for patients suffering from hip fracture. METHODS: Thirty ASA I-III hip fracture patients over 70 years old, who received prehospital morphine, were randomized to receive either a fascia iliaca block using 30 ml of bupivacaine 0.5% with epinephrine 1:200,000 or a sham injection with normal saline. The fascia iliaca block was administered by emergency medicine physicians trained to perform an anatomic landmark-based technique. The primary outcome was the comparison between groups of the longitudinal pain score profiles at rest over the first 45 min following the procedure (numeric rating scale, 0-10). Secondary outcomes included the longitudinal pain score profiles on movement and the comparison over 4 h, 8 h, 12 h, and 24 h after the procedure, along with cumulative intravenous morphine consumption at 24 h. RESULTS: At baseline, the fascia iliaca group had a lower mean pain score than the sham injection group, both at rest (difference = - 0.9, 95%CI [- 2.4, 0.5]) and on movement (difference = - 0.9, 95%CI [- 2.7; 0.9]). These differences remained 45 min after the procedure and the two longitudinal pain score profiles were parallel both for patients at rest and on movement (test of parallelism for patients at rest p = 0.53 and on movement p = 0.45). The same parallel change in pain scores over time was observed over 24 h of follow-up (test of parallelism for patients at rest p = 0.82 and on movement p = 0.12). These results were confirmed after adjustment for gender, ASA score, and cumulative sums of intravenous morphine received pre-procedure and during-follow-up. In addition, there was no difference between the two groups in total cumulative intravenous morphine consumption at 24 h. CONCLUSION: Fascia iliaca block following anatomic landmarks may not provide supplementary analgesia for patients suffering from hip fracture, when low pain scores are reported after prehospital morphine. Additional larger trials will help reach definitive conclusion. TRIAL REGISTRATION NUMBER: Clinicaltrials.gov - NCT02433548 . The study was registered retrospectively.

BACKGROUND: ED overcrowding represents a significant public health problem in developed countries. Frequent users of the emergency departments (FUEDs; reporting 5 or more ED visits in the past year) are often affected by medical, psychological, social, and substance use problems and account for a disproportionately high number of ED visits. Past research indicates that case management (CM) interventions are a promising way to reduce ED overcrowding and improve FUEDs' quality of life. There is, however, very limited knowledge about how to disseminate and implement this intervention on a large scale to diverse clinical settings, including community hospitals and non-academic centers. This paper describes the protocol of a research project aiming to implement a CM intervention tailored to FUEDs in the public hospitals with ED in the French-speaking region of Switzerland and evaluate both the implementation process and effectiveness of the CM intervention. METHODS: This research project uses a hybrid study design assessing both implementation and clinical outcomes. The implementation part of the study uses mixed methods a) to describe quantitatively and qualitatively factors that influence the implementation process, and b) to examine implementation effectiveness. The clinical part of the study uses a within-subject design (pre-post intervention) to evaluate participants' trajectories on clinical variables (e.g., quality of life, ED use) after receiving the CM intervention. We designed the study based on two implementation science frameworks. The Generic Implementation Framework guided the overall research protocol design, whereas the RE-AIM (reach, efficacy, adoption, implementation and maintenance) framework guided the implementation and effectiveness evaluations. DISCUSSION: This research project will contribute to implementation science by providing key insights into the processes of implementing CM into broader practice. This research project is also likely to have both clinical and public health implications. TRIAL REGISTRATION: NCT03641274 , Registered 20 August 2018.

For decades, emergency departments of hospitals in industrialized countries have been dealing with the challenges of a group of patients responsible for a disproportionate number of emergency room visitsâ : the emergency department frequent users. Although they represent only a minority of all emergency department patients, their healthcare can often be complex if not difficult due to their health vulnerability (e. g., psychiatric disorders associated with substance addictions), often aggravated by a precarious psycho-social context (e. g., homelessness, illegal status, poverty, etc.). Taking care of these patients by using a case management approach can promote the development of an interprofessional and coordinated healthcare plan that includes their empowerment.
Depuis plusieurs décennies, les services d'urgences des centres hospitaliers des pays industrialisés doivent faire face aux défis que représente un groupe de patients responsables d'un nombre disproportionné de consultations aux urgencesâ : les «â grands consommateurs des services d'urgencesâ ¼. Bien que ne représentant qu'une minorité de l'ensemble des patients des services d'urgences, leur prise en charge peut s'avérer être souvent complexe, voire difficile, en lien avec leur vulnérabilité sur le plan de la santé, souvent aggravée par un contexte psychosocial précaire. La prise en charge de ces patients, selon une approche de type case management, peut favoriser le développement d'une prise en charge pluridisciplinaire et coordonnée, tout en intégrant ces derniers dans le processus d'aide et de soutien (empowerment).

PURPOSE: Frequent Emergency Department users are likely to experience poor quality of life (QOL). Case management interventions are efficient in responding to the complex needs of this population, but their effects on QOL have not been tested yet. Therefore, the aim of our study was to examine to what extent a case management intervention improved frequent Emergency Department users' QOL in a universal health coverage system. METHODS: Data were part of a randomized controlled trial designed to improve frequent Emergency Department users' QOL at the Lausanne University Hospital, Switzerland. A total of 250 frequent Emergency Department users (≥ 5 attendances during the previous 12 months) were randomly assigned to the control (n = 125) or the intervention group (n = 125). The latter benefited from case management intervention. QOL was evaluated using the WHOQOL-BREF at baseline, two, five and a half, nine, and twelve months later. It included four dimensions: physical health, psychological health, social relationship, and environment. Linear mixed-effects models were used to analyze the change in the patients' QOL over time. RESULTS: Patients' QOL improved significantly (p < 0.001) in both groups for all dimensions after two months. However, environment QOL dimension improved significantly more in the intervention group after 12 months. CONCLUSIONS: Environment QOL dimension was the most responsive dimension for short-term interventions. This may have been due to case management's assistance in obtaining income entitlements, health insurance coverage, stable housing, or finding general health care practitioners. Case management in general should be developed to enhance frequent users' QOL. TRIAL REGISTRATION: http://www.clinicaltrials.gov , Unique identifier: NCT01934322.
