Impact of emergency department length of stay on in-hospital mortality: a retrospective cohort study

BACKGROUND AND IMPORTANCE

Emergency Department (ED) workload may lead to ED crowding and increased ED length of stay (LOS). ED crowding has been shown to be associated with adverse events and increasing mortality. We hypothesised that ED-LOS is associated with mortality.

OBJECTIVE

To study the relationship between ED-LOS and in-hospital mortality.

DESIGN

Observational retrospective cohort study.

SETTINGS AND PARTICIPANTS

From 1 January 2015 to 30 September 2018, all visits by patients aged 15 or older to one of the two ED at Toulouse University Hospital were screened. Patients admitted to the hospital after ED visits were included. Visits followed by ED discharge, in-ED death or transfer to ICU or another hospital were not included.

OUTCOME MEASURE AND ANALYSIS

The primary outcome was 30-day in-hospital mortality. ED-LOS was defined as time from ED registration to inpatient admission. ED-LOS was categorised according to quartiles [<303 min (Q1), between 303 and 433 minutes (Q2), between 434 and 612 minutes (Q3) and >612 min (Q4)]. A multivariable logistic regression tested the association between ED-LOS and in-hospital mortality.

MAIN RESULTS

A total of 49 913 patients were admitted to our hospital after ED visits and included in the study. ED-LOS was not independently associated with in-hospital mortality. Compared to ED-LOS < 303 min (Q1, reference), odd-ratios (OR) [95% CI] of in-hospital mortality for Q2, Q3, and Q4 were respectively 0.872 [0.747-1.017], 0.906 [0.777-1.056], and 1.137 [0.985-1.312]. Factors associated to in-hospital mortality were: aged over 75 years (OR [95% CI] = 4.3 [3.8-4.9]), Charlson Comorbidity Index score > 1 (OR [95% CI] = 1.3 [1.1-1.5], and 2.2 [1.9-2.5] for scores 2 and ≥ 3 respectively), high acuity at triage (OR [95% CI] = 3.9 [3.5-4.4]), ED visit at Hospital 1 (OR [95% CI] = 1.6 [1.4-1.7]), and illness diagnosis compared to trauma (OR [95% CI] = 2.1 [1.7-2.6]). Night-time arrival was associated with decreased in-hospital mortality (OR [95% CI] = 0.852 [0.767-0.947]).

CONCLUSION

In this retrospective cohort study, there was no independent association between ED-LOS before admission to general non-ICU wards and in-patient mortality.

The dental microscope in endodontic education: A feasibility study of a distance learning course

This study aimed to evaluate the feasibility of preclinical training, specifically in root canal preparation, using a virtual educational system equipped with an operating microscope. Ten postgraduate general dentistry trainees and practitioners undergoing postgraduate training in endodontics participated. The telesimulation course included three steps: theory, demonstration of practical work by the teacher and lastly practical training by the participants. The digital environment including the dental microscope was presented, and the feedback was collected with a questionnaire. The majority of participants considered that the online video conference format allowed them to acquire theoretical content but also practical knowledge and skills, owing to the contribution of the operating microscope. The technical feasibility of endodontic telesimulation was demonstrated. The operating microscope has a potential role in distance education, enabling teaching to occur synchronously and collaboratively. This allows learners to interact with each other and demonstrators in real time.

Mass Training In Situ During COVID-19 Pandemic: Enhancing Efficiency and Minimizing Sick Leaves

INTRODUCTION

Avoiding coronavirus disease 2019 (COVID-19) work-related infection in frontline healthcare workers is a major challenge. A massive training program was launched in our university hospital for anesthesia/intensive care unit and operating room staff, aiming at upskilling 2249 healthcare workers for COVID-19 patients' management. We hypothesized that such a massive training was feasible in a 2-week time frame and efficient in avoiding sick leaves.

METHODS

We performed a retrospective observational study. Training focused on personal protective equipment donning/doffing and airway management in a COVID-19 simulated patient. The educational models used were in situ procedural and immersive simulation, peer-teaching, and rapid cycle deliberate practice. Self-learning organization principles were used for trainers' management. Ordinary disease quantity in full-time equivalent in March and April 2020 were compared with the same period in 2017, 2018, and 2019.

RESULTS

A total of 1668 healthcare workers were trained (74.2% of the target population) in 99 training sessions over 11 days. The median number of learners per session was 16 (interquartile range = 9-25). In the first 5 days, the median number of people trained per weekday was 311 (interquartile range = 124-385). Sick leaves did not increase in March to April 2020 compared with the same period in the 3 preceding years.

CONCLUSIONS

Massive training for COVID-19 patient management in frontline healthcare workers is feasible in a very short time and efficient in limiting the rate of sick leave. This experience could be used in the anticipation of new COVID-19 waves or for rapidly preparing hospital staff for an unexpected major health crisis.

Hydroxyzine for lowering patient's anxiety during prehospital morphine analgesia: A prospective randomized double blind study

STUDY OBJECTIVE

Hydroxyzine is an antihistamine drug used for symptomatic relief of anxiety and tension. We hypothesized that managing the anxiety of patients with severe pain by adding hydroxyzine to a conventional intravenous morphine titration would relieve their pain more effectively.

METHODS

This was a randomized, double-blind, controlled group study of prehospital patients with acute pain scored greater than or equal to 6 on a 0-10 verbal numeric rating scale (NRS). Patients'anxiety was measured with the self-reported Face Anxiety Scale (FAS) ranking from 0 to 4. The percentage of patients with pain relief (NRS score ≤ 3) 15 min after the first injection was the primary outcome.

RESULTS

One hundred forty patients were enrolled. Fifty-one percent (95% CI 39% to 63%) of hydroxyzine patients versus 52% (95% CI 40% to 64%) of placebo patients reported a pain numeric rating scale score of 3 or lower at 15 min. Ninety-one percent (95% CI 83% to 98%) of patients receiving hydroxyzine reported no more severe anxiety versus 78% (95% CI 68% to 88%) of patients with placebo (p > 0.05). Adverse events were minor, with no difference between groups (6% in hydroxyzine patients and 14% in placebo patients).

CONCLUSION

Addition of hydroxyzine to morphine in the prehospital setting did not reduce pain or anxiety in patients with acute severe pain and therefore is not indicated based on our results.

Factors associated with Emergency Medical Dispatcher request and residents' inappropriate transfers from Nursing Homes to Emergency Department

PURPOSE

In the last decades, the amount of emergency department (ED) transfers of nursing home (NH) residents has disproportionally increased in western countries. The main role of emergency medical dispatcher (EMD) among this population is to refer residents to EDs in the most appropriate way. The aim of this study was to assess risk factors of inappropriate transfers from NH to ED after EMD request.

METHODS

This research was a secondary analysis of a prospective observational multicenter study carried out in 17 EDs entitled FINE aimed to assess potentially inappropriate transfer prevalence among this population. Inappropriate transfers were determined in the FINE study threw a standardized approach by a unique expert team.

RESULTS

Overall, 572/1037 (55.2%) of residents were transferred to the ED after an EMD's decision. Among them, 92/572 (16.1%) transfers was defined as inappropriate. The average age was 87.3 years old (SD = 0.3). The main reason for ED transfer were falls (217/572, 37.9%). In multivariate analysis, the presence of a Special Care Unit in NH was significantly associated with a high rate of inappropriate transfer (OR 1.78; 95 CI [1.07-2.93]; p = 0.02) whereas a medical examination by a general practitioner before the transfer (OR 0.55; 95 CI [0.33-0.83]; p = 0.02) and a prompt access to psychiatric advice (OR 0.54; 95 CI [0.33-0.84]; p = 0.007) were associated with a low rate of potentially inappropriate transfer.

CONCLUSION

Promoting onsite medical assessment and partnership thanks to available geriatrician's advice may help the emergency medical dispatcher to improve the appropriateness of residents' transfer from Nursing Home to the emergency department.

Does prior exposure to clinical critical events influence stress reactions to simulation session in nursing students: A case-control study

BACKGROUND

Simulation is a pedagogical method known to be a generator of stress, that could be influenced by previous stressful experiences.

OBJECTIVES

The purpose of this study was to determine the impact of previous experience with a clinical critical event on the stress experienced by nursing students during simulation session of critical events, and on the stress experienced during clinical critical events subsequent to the training.

DESIGN

Observational case-control study.

SETTINGS

Four critical event scenarios were created using full-scale simulation.

PARTICIPANTS

Two hundred and fifteen undergraduate nursing students of semester four. The control group (n = 112) consisted of learners who had not previously experienced a critical event. The prior exposure group (n = 103) consisted of learners who had experienced a critical event prior to the course.

METHODS

Stress levels were assessed using the self-report stress numerical rating scale-11.

RESULTS

There was no significant difference in the level of stress between the prior exposure group and the control group before, during or expected after the simulation session. A significant decrease in stress was observed in both groups from before the course to during the session (p < 0.05) and expected after the session (p < 0.05). There was no significant difference between the expected post-session stress level and the stress levels reported four months after the training (p = 0.966). At four months, there was no significant difference in stress levels between the groups (p = 0.212).

CONCLUSIONS

The prior experience of a clinical critical event before a simulation course did not influence their reported stress level during the simulation session. Conversely, simulation-based training of critical situations appears to reduce the level of self-assessed stress during critical events in clinical practice after the training.

COVID-19 and French Medical Maritime Teleconsultation

Introduction: The coronavirus disease 2019 (COVID-19) epidemic has impacted both land and maritime health services. The purpose of this study is to describe the calls received by the Tele-Medical Assistance Service (TMAS) in relation to this epidemic. Methods: From March 1 to 30 April 30, 2020, all records coded by TMAS doctors as "influenza due to an unidentified virus" were extracted. The following data were collected: patients' age, gender, nationality, role on board, type of ship, area of navigation, reason for the teleconsultation, patient's symptoms, whether or not a COVID test had been carried out, and treatment given. The data were analyzed in two groups, depending on the reason for the consultation: teleconsultation for suspected COVID patients and teleconsultation for non-COVID patients for whom the call was nevertheless related to the COVID pandemic. Results: Sixty-one records were included-51 for suspected COVID patients and 10 records for COVID-related problems (six patients whose treatment had stopped due to shortage of medication/one patient reporting a psychiatric problem associated with isolation, three patients followed up as contact cases). Forty-five patients presented with fever when the first call was made (88%) and 39 had a cough (76%). On closure of the medical records, 33 were receiving treatment on board (65%), 10 had disembarked (20%), 1 had been rerouted (2%), and 7 had been evacuated (13%). Discussion: TMAS was able to aid professional sailors as well as passengers/recreational sailors in terms of telemedicine (diagnosis and monitoring), logistics (barrier actions and isolation), and operations (evacuation and repatriation).

Cutaneous impact location: a new tool to predict intracranial lesion among the elderly with mild traumatic brain injury?

Background

Mild traumatic brain injury is the leading cause of arrivals to emergency department due to trauma in the 65-year-old population and over. Recent studies conducted in ED suggested a low intracranial lesion prevalence. The objectives of this study were to assess the prevalence and risk factors of intracranial lesion in older patients admitted to emergency department for mild traumatic brain injury by reporting in the emergency department the precise anamnesis of injury and clinical findings.

Methods

Patients of 65 years old and over admitted in emergency department were prospectively included in this monocentric study. The primary outcome was the prevalence of intracranial lesion threw neuroimaging.

Results

Between January and June 2019, 365 patients were included and 66.8% were women. Mean age was 86.5 years old (SD = 8.5). Ground-level fall was the most common cause of mild traumatic brain injury and occurred in 335 patients (91.8%). Overall, 26 out of 365 (7.2%) patients had an intracranial lesion. Compared with cutaneous frontal impact (medium risk group), the relative risk of intracranial lesion was 2.54 (95% CI 1.20 to 5.42) for patients with temporoparietal or occipital impact (high risk group) and 0.12 (95% CI 0.01 to 0.93) for patients with facial impact or no cutaneous impact (low risk group). There was not statistical increase in risk of intracranial injury with patients receiving antiplatelets (RR = 1.43; 95% CI 0.68 to 2.99) or anticoagulants (RR = 0.98; 95% CI 0.45 to 2.14).

Conclusion

Among patients of 65 years old and over, the prevalence of intracranial lesion after a mild traumatic brain injury was similar to the younger adult population. The cutaneous impact location on clinical examination at the emergency department may identify older patients with low, medium and high risk for intracranial lesion.

Winter virus season impact on acute dyspnoea in the emergency department

OBJECTIVE

To compare the epidemiology of dyspnoea presented to emergency departments (EDs) during and of winter virus season (WVS).

METHODS

This is a monocentric retrospective cohort study. All patients attending to the ED of the Rangueil University Hospital (Toulouse, France) for dyspnoea in September 2016 (off WVS period) and January 2017 (during WVS period) were included. The primary endpoint was the final diagnosis. The patients' medical profiles, care duration, seriousness and futures were studied as secondary endpoints.

RESULTS

A total of 395 patients were studied: 125 patients during off-peak influenza season and 270 patients during the peak influenza season. The incidence of patients attending because of dyspnoea increased significantly during WVS (4.2% of ED presentations during the off WVS period versus 8.4% during the WVS period, P < 0.001). Patients attending the ED because of dyspnoea during WVS period were significantly older with more extensive medical backgrounds and more serious diseases. Most of those patients were hospitalized (54%), and largely in the geriatrics department.

CONCLUSION

The incidence of patients attending because of dyspnoea doubled during the WVS period, with patients who were older and had more complex histories. This time-consuming population largely requires hospitalization and may be one of the causes of the emergency department's overcrowding during epidemics.

Development and Evaluation of a Virtual Research Environment to Improve Quality of Care in Overcrowded Emergency Departments: Observational Study

BACKGROUND

Despite a wide range of literature on emergency department (ED) overcrowding, scientific knowledge on emergency physicians' cognitive processes coping with overcrowding is limited.

OBJECTIVE

This study aimed to develop and evaluate a virtual research environment that will allow us to study the effect of physicians' strategies and behaviors on quality of care in the context of ED overcrowding.

METHODS

A simulation-based observational study was conducted over two stages: the development of a simulation model and its evaluation. A research environment in emergency medicine combining virtual reality and simulated patients was designed and developed. Afterwards, 12 emergency physicians took part in simulation scenarios and had to manage 13 patients during a 2-hour period. The study outcome was the authenticity of the environment through realism, consistency, and mastering. The realism was the resemblance perceived by the participants between virtual and real ED. The consistency of the scenario and the participants' mastering of the environment was expected for 90% (12/13) of the participants.

RESULTS

The virtual ED was considered realistic with no significant difference from the real world with respect to facilities and resources, except for the length of time of procedures that was perceived to be shorter. A total of 100% (13/13) of participants deemed that patient information, decision making, and managing patient flow were similar to real clinical practice. The virtual environment was well-mastered by all participants over the course of the scenarios.

CONCLUSIONS

The new simulation tool, Virtual Research Environment in Emergency Medicine, has been successfully designed and developed. It has been assessed as perfectly authentic by emergency physicians compared with real EDs and thus offers another way to study human factors, quality of care, and patient safety in the context of ED overcrowding.

Levocetirizine and Prednisone Are Not Superior to Levocetirizine Alone for the Treatment of Acute Urticaria: A Randomized Double-Blind Clinical Trial

STUDY OBJECTIVE

We evaluate the efficacy of a 4-day course of prednisone added to antihistamine for the management of acute urticaria in an emergency department (ED).

METHODS

In this double-blind randomized clinical trial, patients were eligible for inclusion if aged 18 years or older and with acute urticaria of no more than 24 hours' duration. Patients with anaphylaxis or who had received antihistamines or glucocorticoids during the previous 5 days were not included. In addition to levocetirizine (5 mg orally for 5 days), patients were assigned to receive prednisone (40 mg orally for 4 days) or placebo. The primary endpoint of the study was itching relief 2 days after the ED visit, rated on a numeric scale of 0 to 10. Secondary endpoints were rash resolution, relapses, and adverse events.

RESULTS

A total of 100 patients were included, 50 in each group. Seven patients in the prednisone group and 8 in the placebo group discontinued treatment. At 2-day follow-up, 62% of patients in the prednisone group had an itch score of 0 versus 76% of those in the placebo group (Δ 14%; 95% confidence interval -31% to 4%). Thirty percent of patients in the prednisone group and 24% in the placebo group reported relapses (Δ 6%; 95% confidence interval -23% to 11%). Mild adverse events were reported by 12% of patients in the prednisone group and 14% in the placebo group.

CONCLUSION

The addition of a prednisone burst did not improve the symptomatic and clinical response of acute urticaria to levocetirizine. This study does not support the addition of corticosteroid to H₁ antihistamine as first-line treatment of acute urticaria without angioedema.

Predicting morphine related side effects in the ED: An international cohort study

STUDY OBJECTIVES

Morphine is the reference treatment for severe acute pain in an emergency department. The purpose of this study was to describe and analyse opioid-related ADRs (adverse drug reactions) in a large cohort of emergency department patients, and to identify predictive factors for those ADRs.

METHODS

In this prospective, observational, pharmaco-epidemiological international cohort study, all patients aged 18years or older who were treated with morphine were enrolled. The study was done in 23 emergency departments in the US and France. Baseline numerical rating scale score and initial and total doses of morphine titration were recorded. Logistic regression analysis was used to study the effects of demographic, clinical and medical history covariates on the occurrence of opioid-induced ADRs within 6h after treatment.

RESULTS

A total of 1128 patients were included over 10months. Median baseline initial pain scores were 8/10 (7-10) versus 3/10 (1-4) after morphine administration. Median titration duration was 10min (IQR, 1-30). The occurrence of opioid-induced ADRs was 25% and 2% were serious. Patients experienced mainly nausea and drowsiness. Medical history of travel sickness (odds ratio [OR], 1.7; 95% confidence interval [CI], 1.01-2.86) and history of nausea or vomiting post morphine (OR, 3.86; 95% CI, 2.29-6.51) were independent predictors of morphine related ADRs.

CONCLUSION

Serious morphine related ADRs are rare and unpredictable. Prophylactic antiemetic therapy could be proposed to patients with history of travel sickness and history of nausea or vomiting in a postoperative setting or after morphine administration.

Prehospital mechanical ventilation of a critical cardiac tamponade

Mechanical ventilation of a critical cardiac tamponade is a high-risk situation that can lead to asystolic cardiac arrest. We report a prehospital mechanical ventilation of a penetrating cardiac injury complicated with tamponade. Onset diagnosis of the circulatory arrest allowed by prehospital continuous ultrasonography led to earlier initiation of the resuscitation and might have favored successful outcome. Electrocardiographic signs are too late to diagnose circulatory arrest.

Nebulized morphine for analgesia in an emergency setting

OBJECTIVE

To evaluate the efficacy and safety of inhaled morphine delivered in patients experiencing severe acute pain in an emergency setting.

PATIENTS AND METHODS

Patients were eligible for inclusion if they were aged 18 years or older, with a severe acute pain defined by a numerical rating scale (NRS) score of 60/100 or higher. The intervention involved administering a single dose of 0.2 mg/kg morphine nebulized using a Misty-Neb nebulizer system. NRSs were recorded and were repeated at 1, 3, 5, and 10 minute after the end of inhalation (T10). The protocol-defined primary outcome measure was pain relief (defined by an NRS score of 30/100 or lower) at T10. Secondary outcomes included differences between pain scores at baseline and at T10 and incidence of adverse events.

RESULTS

A total of 28 patients were included in this study. No patient experienced pain relief 10 minutes after the end of inhalation, and no adverse effects were recorded. Respective initial and final median NRS scores were 80 (70-90) and 70 (60-80), p < 0.0001. Despite achieving statistical significance, the value of this point estimate is less than the 14 NRS difference that was defined a priori as representing a minimum clinically significant difference in pain severity.

CONCLUSION

0.2 mg/kg nebulized morphine is not effective in managing acute pain in an emergency setting. In spite of the potential advantages of the pulmonary route of administration, opioids should be intravenous prescribed at short fixed intervals to control severe acute pain in an emergency setting.
