Post-Pandemic Evolution of Suicide Risk in Children and Adolescents Attending a General Hospital Accident and Emergency Department.

Lockdowns and other health protective measures, such as social distancing, imposed during the COVID-19 pandemic nurtured unprecedented levels of stress and social isolation around the world. This scenario triggered an increase in suicide thoughts and self-harm behaviours among children and young people. However, the longer-term impact of the pandemic on children's and adolescents' mental health, especially with regard to self-harm, is still to be fully discovered. We carried out a retrospective study where we collected data related to suicide ideation and self-harm behaviours in all patients aged under 18 that required on-call psychiatric services at the General Hospital Accident and Emergency (A&E) department in Salamanca, Spain, during 2019 (pre-pandemic) and in both 2021 and 2022 to capture possible variation at different time points during the post-pandemic period. A total of 316 patients aged under 18 were seen by on-call psychiatric services at the A&E department during the three time periods: 78 in 2019, 98 in 2021 and 140 in 2022. The mean age was 15.12 (SD 2.25) and females represented more than twice the number of males each year. More than half of all patients assessed during 2022 disclosed suicide thoughts, whilst in 2019, it was near 25%. This increase in suicide ideation rates was more marked among females (X2 = 15.127; p = 0.001), those aged over 15 (X2 = 16.437; p < 0.001) and/or those with a previous history of mental health problems (X2 = 17.823; p < 0.001). We identified an increase in the proportion of males with suicide ideas, especially between 2021 and 2022 (X2 = 8.396; p = 0.015). Our study suggests that children's and adolescents' demand for urgent mental healthcare and their clinical presentations in A&E departments with suicide thoughts and/or self-injuries do not seem to be declining after the pandemic but increasing over time. More research is warranted to understand possible factors involved in this sustained upward trend.

Pediatric COVID-19: clinical and epidemiological data of 1303 cases in a general hospital in Brazil.

This study aimed to describe the clinical characteristics of the pediatric population with COVID-19 in an Emergency Department (ED) of a Brazilian general hospital. Epidemiological and clinical data of patients younger than 20 years old were collected from patients' medical records from February 2020 to July 2021. Most of the epidemiological data described pertains to hospitalized patients. We also reviewed coinfections, treatment, and outcomes and compared the first and second waves of COVID-19. We identified a total of 1303 episodes of SARS-CoV-2 infection. The median time from symptom onset to diagnosis was three days. Symptoms were present in 92.3% of the patients. The most common symptoms were fever (45.2%), nasal congestion/discharge (44.2%), and cough (39.4%). Chest radiography and tomography were performed in 7.7 and 3.3% of cases, with abnormal findings in 29.7 and 53.4%, respectively. Hospital admissions occurred in 3.5% of patients, mainly in the presence of comorbidities, in children under five years old and in those who presented to the ED during the first wave of COVID-19. Coinfection with a viral agent was identified in 20% of the 71 cases tested in this study, and a positive rapid test for Streptococcus pyogenes was found in 8% of the 174 cases tested, with no impact of these coinfections on hospitalization. We found that COVID-19 was a mild disease in most children in our study population, with most hospitalizations and readmissions occurring during the first wave of COVID-19.

Improved interpretable machine learning emergency department triage tool addressing class imbalance.

The Score for Emergency Risk Prediction (SERP) is a novel mortality risk prediction score which leverages machine learning in supporting triage decisions. In its derivation study, SERP-2d, SERP-7d and SERP-30d demonstrated good predictive performance for 2-day, 7-day and 30-day mortality. However, the dataset used had significant class imbalance. This study aimed to determine if addressing class imbalance can improve SERP's performance, ultimately improving triage accuracy. The Singapore General Hospital (SGH) emergency department (ED) dataset was used, which contains 1,833,908 ED records between 2008 and 2020. Records between 2008 and 2017 were randomly split into a training set (80%) and validation set (20%). The 2019 and 2020 records were used as test sets. To address class imbalance, we used random oversampling and random undersampling in the AutoScore-Imbalance framework to develop SERP+-2d, SERP+-7d, and SERP+-30d scores. The performance of SERP+, SERP, and the commonly used triage risk scores was compared. The developed SERP+ scores had five to six variables. The AUC of SERP+ scores (0.874 to 0.905) was higher than that of the corresponding SERP scores (0.859 to 0.894) on both test sets. This superior performance was statistically significant for SERP+-7d (2019: Z = -5.843, p < 0.001, 2020: Z = -4.548, p < 0.001) and SERP+-30d (2019: Z = -3.063, p = 0.002, 2020: Z = -3.256, p = 0.001). SERP+ outperformed SERP marginally on sensitivity, specificity, balanced accuracy, and positive predictive value measures. Negative predictive value was the same for SERP+ and SERP. Additionally, SERP+ showed better performance compared to the commonly used triage risk scores. Accounting for class imbalance during training improved score performance for SERP+. Better stratification of even a small number of patients can be meaningful in the context of the ED triage. Our findings reiterate the potential of machine learning-based scores like SERP+ in supporting accurate, data-driven triage decisions at the ED.

HPB P48 Liver Abscess Secondary to Cocktail Stick Migration Following Accidental Ingestion

Abstract Background Liver abscess formation following foreign body ingestion is rare. This may occur if the foreign body is lodged in the upper gastrointestinal tract and persists. Initial management consists of antibiotics with or without percutaneous abscess drainage. However, referral to the regional HPB unit may need to be considered to discuss foreign body retrieval, especially if it is located within the liver parenchyma itself, in order to treat persistent sepsis or prevent abscess recurrence in the future. Methods A 38-year-old gentleman, previously healthy, presented to the emergency department of a district general hospital with nausea, upper abdominal pain, and fever. He stated that he had accidentally ingested a piece of a wooden cocktail stick while eating some weeks back. Leucocytosis and raised inflammatory markers were present on bloodwork. Computed tomography revealed a 6 cm hypoattenuating lesion in the left lobe of the liver, which demonstrated features of a hepatic abscess on magnetic resonance imaging. Abdominal ultrasound visualised a 4 cm linear hyperechoic structure within the hypoechoic lesion, raising the suspicion of foreign body retention with abscess formation. Results The fever subsided, and symptoms resolved with antibiotics. Follow-up imaging revealed abscess resolution with foreign body persistence in the liver. He was referred to the regional HPB unit and underwent laparoscopy for foreign body removal. A fistulous communication between liver segment II and lesser curvature of the stomach was seen and disconnected using diathermy. Minimal pus was drained and the foreign body retrieved. The gastric perforation was sealed using a linear stapling device. A nasogastric tube was left in the stomach until the patient tolerated a liquid diet and discharged on the first post-operative day. He remains well on follow-up. Conclusions This case highlights that scrupulous history taking and imaging review are required for a timely diagnosis of foreign body retention.

Psychiatric referrals to the general hospital emergency department: are we being effective?

General hospital emergency departments (GHEDs) are notoriously overcrowded. This is caused, in part, by ineffective referrals, that is to say referrals that do not require medical examination or other interventions in the context of a general hospital. This study aims to investigate the contribution of psychiatric referrals to this issue, to identify potential determinants of these referrals and offer means to reduce them. Retrospective data were collected from psychiatric admission files within a GHED of a tertiary-care city hospital over a 1 year period. Two experienced clinicians separately reviewed each file to determine rationale of referrals according to predetermined criteria. A total of 2,136 visits included a psychiatric examination, 900 (42.1%) were determined "effective," and 1,227 (57.4%) were deemed "potentially ineffective." The leading causes for potentially ineffective referrals to a GHED were psychiatric illness exacerbation (43.4%), and suicidal ideations (22%). Most referrals (66.9%) were initiated by the patient or their family, and not by a primary care physician or psychiatrist. More than half of the psychiatric referrals did not necessarily require the services of a general hospital, and may be more suitable for referral to a dedicated psychiatric facility. Ineffective referrals to the GHED pose a burden on general hospital resources, and may be less effective for the psychiatric patients. This calls for clear guidelines for the provision of optimal emergency treatment for mental-health patients.

We’re Open: Caring for the Walking Well in a Rural Emergency Department

Emergency departments (EDs) are increasingly unable to cope with patient volume, leading staff to question the arrival of those seeking non-urgent care. However, these patients ideally should be afforded appropriate management and treatment. In 2014, the Carbonear General Hospital ED in Newfoundland and Labrador took decisive action, engaging front-line staff and shifting the focus of care away from why patients were visiting to prioritize how best to treat those who did. By 2019, the ED had not needed to resort to hallway medicine, despite a visit volume that increased to 30,000 patients over five years, and staff grew into a close-knit, quality improvement and community force. From this experience, it is evident that small investments in education and system redesign can shift attitudes toward ED care for patients, and provide support for primary care in the community. It has already started in one hospital — we’re open for assistance with primary and non-urgent care.

Early Management of Paediatric Wrist and Forearm Fractures in a Busy District General Hospital Emergency Department: A Retrospective Cohort Comparison Study and Audit of BOAST Guidelines.

In response to the strain that the COVID-19 pandemic put on hospitals in the UK, the British Orthopaedic Association, in May 2021, set out British Orthopaedic Association Standards for Trauma and Orthopaedics (BOAST) guidelines for the early management of distal forearm fractures in children. Following this, a local pathway was introduced at our Trust to manage these injuries in the Emergency Department (ED).The aim of this audit was to monitor compliance with the BOAST guidelines and compare the practice with a similar pre-COVID cohort. A fixed-date retrospective cohort study was conducted that included cases that presented to the emergency department during a six-month period (August 1, 2021 to January 31, 2022). Data was analysed for rates of primary EDmanipulation, documentation of consent and neurovascular status in the notes, orthogonal X-ray data, time till the clinic follow-up, theatre time saved and complications. The ED fracture manipulation rate was also compared with another similar pre-COVID cohort (August 1, 2019 to January 31, 2020) to look for any improvement in the practice. A total of 86.31% cases were found to have primary fracture manipulation in the ED following the introduction of Trust guidelines in accordance with the BOAST recommendations. This is an improvement in comparison to the 31.94% fracture manipulation rate before the COVID pandemic. Implementation of the Trust pathway in accordance with the BOAST guidelines along with staff education has standardized the practice at our Trust. It saved approximately 63 hours of trauma theatre time for the six-monthdata collection period. Our findings also suggest that this has favourable outcomes for the patients with no complications.

Assessment of the Peradeniya Organophosphorus Poisoning Scale as a Severity and Prognostic Marker in Patients With Acute Organophosphorus Poisoning Presenting to an Emergency Medicine Department.

Background Organophosphorus (OP)compound poisoning is the most common toxicological medical emergency in India, where the majority of the population lives on agriculture. The Peradeniya Organophosphorus Poisoning (POP) scale can be a simple and effective system to determine the need for ventilatory support early in the course of admission. The objective of this study was to evaluate the prognostic value of the clinical parameters of the POP scale in predicting the severity of organophosphorus compound poisoning, by comparing early predicted patient prognosis evaluated by the POP scale on admission with the patient outcome. Methods This was a prospective observational study of acute organophosphorus compound poisoning presenting to the emergency department of Sir Sayajirao General (SSG) Hospital and Medical College, Baroda. We included patients over 12 years of age with a history of, or symptoms suggestive of, acute OP poisoning. The patients receivedinitial resuscitation according to airway, breathing, circulation, disability, and exposure simultaneously with decontamination and gastric lavage by Ryle's tube. They also received the standard antidotes of atropine and pralidoximeimmediately. We appliedthe POP scale to each patient uponadmission and graded the poisoning severity as mild (a POP scale score of 0-3), moderate (4-7), or severe (8-11). This scale assessed the patients' need for mechanical ventilation and ICU management and their final clinical outcome. Results We enrolled 60 patients in the study. Most of themwere under 20 years of age, and 65% of them were male. Social laborers were the major population, and most of them had suicidal intention. Monocrotophos was the most commonly consumed OP compound. Most of the patients were brought to the hospital within two to sixhours of consumption. Vomiting and profuse secretions were the primary presenting symptoms. A majority of the patients (47) fell into the mild POP scale range. None of the patients had severe poisoning. Out of 60 patients, 49 patients improved and 11 patients died. Seven patients (15%) with mild POP scale scores and four patients (31%) with moderate scores died. Overall, 61.7% of patients with mild POP scale scores and 100% of patients with moderate scores needed mechanical ventilation. Conclusion The POP scale is an effective tool to measure severity and make a prognosisin patients with acute OP compound exposure. It may be asimple, inexpensive tool that may help predict the need for ventilatory support at admission. Early identification of danger signs may help in the reduction of mortality and morbidity when resources are limited. However, we found incorporating other clinical parameters and biochemical markers provides better prognostication than using the POP scale alone.

Cultural and religious barriers in the Middle East leading to delayed management of acute HIV case resulting in irreversible blindness: a case report.

A 26-year-old male who resides in a country in the Middle East visited the local general hospital emergency department on 17 July 2018. He presented with symptoms of persistent upper respiratory tract infection, dysphagia, and generalized fatigue. Denied any previous history of sexual contact, smoking, drinking, or using illicit drugs. This patient repeatedly attended the emergency department seeking medical attention and was treated for viral and bacterial upper respiratory tract symptoms by conservative and antibiotic therapy, yielded in short term relief but recurrence and worsening symptoms, especially dysphagia symptoms. On examination, the patient looked unwell, cachectic, and frail with normal vital signs and no positive findings on chest and abdominal examination; however, Ear Nose and Throat and oral examination revealed extensive oropharyngeal candidiasis. That is when he was suspected of having an immunodeficiency syndrome of some sort, and based on those serious findings, he was advised hospital admission for further investigations, diagnosis and management. The patient refused hospital admission against medical advice despite all the potential risks explained clearly, as he had a pre-planned family reunion holiday to Turkey, which was again strongly advised against as likely he will deteriorate while on holiday, but he went on with his plan, accordingly, oropharyngeal candidiasis was successfully treated with oral antifungal tablets, pending further investigations and definitive management. Then in 24 July 2018, he travelled to Turkey, where he developed symptoms of shortness of breath and dry a cough then he became systemically unwell and was admitted to a local hospital in Turkey where he was diagnosed with a lower respiratory tract infection and treated with intravenous antibiotics for 7 days; then on 6 August 2018, he flew back on an emergency flight to his home country, where he was admitted to the acute medical admission unit and arranged to have patient laboratory investigations. The results revealed positive HIV infection with a plasma HIV viral load was greater than 3000000 copies/ml, and advanced immunosuppression with CD3+/CD4+ T-lymphocyte was 40 cells/mm3. The social aspect of this case was apparent from denying sexual contact. The patient did not have any history of surgical operations, no family history of HIV infection, no previous blood transfusion, or use of contaminated syringes. By exclusion sexual mode of transmission is the only possible way of contracting HIV infection in this case, considering the fact that he was outside his country as single man for few years while studying. In the Middle East countries, due to religious and cultural reservations coupled with HIV diagnosis stigma, the diagnosis of the serious sexually transmitted infections such as HIV is usually delayed, as a result these patients will go on and develop late-stage disease and irreversible complications when diagnosed, entering the AIDS stage with rapid progression of irreversible complications like Cytomegalovirus, Ear Nose and Throat retinitis and blindness before they start definitive treatment. The oropharyngeal candidiasis and repeated upper and lower respiratory tract infections that are non-responding to therapy are usually red flag signs of immunosuppression, which warrants high clinical vigilance from the clinician side to take a detailed sexual history and rule out acute HIV infection by testing for it at early stages, in patients with high clinical suspicion , in addition to the other possible causes of immunosuppression. Therefore, assuring confidentiality, taking a careful sexual history and gathering data in an acceptable way for these patients and considering a holistic approach yield a better management outcome.

Electric Scooter Injuries in Tampa, Florida, Are Associated With High Rates of Head Injury, Hospital Admission, and Emergency Medical Service Transport and Low Rates of Helmet Use.

Background Standing electric scooters (e-scooters) were introduced in Tampa, Florida, in 2019. We reviewed 292 e-scooter injury cases at the Tampa General Hospital Emergency Department (ED) to determine what insights we could gain. We sought to identify the characteristics of such presentations, including chief complaint (CC), patient age, day of the week, time of day, length of stay, disposition, acuity, and means of arrival to the ED. We were particularly interested in studying the rates of hospital admission, Emergency Medical Service (EMS) transport, emergent acuity presentations, and head injuries. We also sought to identify the prevalence of alcohol use prior to e-scooter accidents and its effect on the above factors. Methodology This was a retrospective chart review and was exempt from the University of South Florida's Institutional Review Board approval (STUDY004031). Data from routine clinical care in the Tampa General Hospital ED, a Level-1 Trauma Center ED in Tampa, Florida, from July 19, 2019, to May 30,2022, were collected through an operational report within the business intelligence infrastructure of the hospital's electronic medical record system. Data from patients with scooter injury-related encounter codes were extracted to an electronicdata capture form and deidentified. Narratives were reviewed to exclude uncertain cases (e.g., patients with moped, kick scooter, mobility scooter injuries, etc.) and to flag for alcohol endorsement, altered mental status, helmet usage, and head injuries that were not listed as the CC. CC, means of arrival, acuity, disposition, arrival/departure day of week, and arrival/departure hour were collected. Data analysis was completed using Microsoft Excel version 16.5 (Microsoft Corp., Redmond, WA, USA) and SPSS Statistics version 28.0 (IBM Corp., Armonk, NY, USA). Results A total of 292 of 442 collected cases remained after removing irrelevant flags. Overall, 30.8% (n = 90) of patients were between the ages of 21 and 30, and most patients presented on weekends and nights. Moreover, 40.8% (n = 119) suffered head injuries, 40.8% (n = 119) arrived via EMS, 31.5% (n = 92) were admitted to the hospital, and 18.8% (n = 55) were designated as emergent acuity. Apart from the admission rate, these rates were all higher among alcohol endorsers (39, 13.4%) than non-endorsers (253, 86.6%). Only 2.1% of patients endorsed helmet use. Conclusions We found higher rates of hospital admission and EMS transports in our ED than many previous studies in urban areas have reported. Our data suggest that alcohol use increases the risk of more serious e-scooter injuries, characterized by higher acuity, EMS transport rate, and head injuries among alcohol endorsers. These findings are highly relevant due to the rapidly growing e-scooter presence across the United States and may serve to inform hospitals and EMS systems regarding their role in injury management, as well as future policy regarding their safe use.

Quality Improvement Project: Optimizing Compliance with NICE CG176 Head Injury CT Time Standards at Wexford General Hospital Emergency Department

Introduction:Head trauma is a high-risk presentation to the emergency department (ED). Preventing secondary brain injury through earlier diagnosis and intervention relies on timely access to head CT. Wexford General Hospital (WGH) ED uses NICE guidelines, which recommend specific timeframes for acquiring CT in head trauma. Following an audit demonstrating low compliance to NICE CG176 time standards in 2020 (34%), a quality improvement project was undertaken to optimize imaging pathways for head trauma.Method:94 head trauma CT scans were analyzed over a two-month period (June 14, 2022-August 14, 2022) from the NIMIS and IPMS databases to establish current time compliance and median wait times for CT.Following the implementation of a head injury assessment proforma at triage to prompt earlier evaluation of high-risk head injuries, 108 head trauma CT’s were reviewed over a two-month period (August 15, 2022-October 15, 2022) to determine if these parameters improved.Unpaired, two-tailed Mann-Whitney’s test was used to compare median wait times from triage to CT. Two-tailed Chi-square test was used to compare overall compliance rates.Results:Overall ED compliance to NICE time standards improved following implementation of the proforma (43% vs. 36%, p=0.401).For CT scans that were indicated within one hour, there was a statistically significant decrease in median wait time from triage to CT (134mins vs. 186mins, p=0.046). There was also a decrease in median wait time for scans indicated within 8 hours; however, this did not reach the threshold for statistical significance (216mins vs. 275mins, p=0.230).Conclusion:Although there was an overall reduction in wait times for CT, this did not translate to a significant improvement in compliance rates to NICE CG176 time standards. This suggests that, despite earlier identification of these high-risk head injuries at triage, other systemic barriers to obtaining head CT are present and warrant further investigation.

Compliance with The National Institute for Health and Care Excellence (NICE) Guideline (NG158) Venous Thromboembolic Diseases: Diagnosis, Management, and Thrombophilia Testing; Proximal Lower Limb Venous Ultrasound Time Standards at Wexford General Hospital

Introduction:The consequences of missed lower-limb deep vein thromboses (DVT) can be life-threatening. Similarly, inappropriate treatment with anticoagulation in low-risk patients carries a significant risk of harm. Early diagnosis and appropriate treatment with anticoagulation rely on timely ultrasound access. The National Institute for Health and Care Excellence (NICE) recommends timeframes for ultrasound acquisition based on Well’s score and D-dimer value.If rapid ultrasound (Point of care Ultrasound POCUS in our context) demonstrates no features of DVT, it is safe to arrange follow-up scan within eight days without empiric anticoagulation. If, however, no bedside ultrasound is performed, anticoagulation is commenced until a formal scan excludes DVT. NG158 recommends this scan be performed within 24 hours. This audit investigated our compliance with NG158 time standards at Wexford General Hospital (WGH) emergency department (ED).Method:Electronic records for patients undergoing formal ultrasound for suspected DVT between 08/01/2022-10/13/2022 were reviewed using the hospital’s databases. Charts were reviewed to determine if POCUS was performed. In total, 42 records met selection criteria. Audit Committee governance review was obtained. Fisher’s exact test was used to compare compliance rates between those that underwent bedside ultrasound and those that did not.Results:Overall compliance with NG158 was 40.5%. Compliance rates for those offered bedside ultrasound were significantly higher than those that weren’t (58.3% vs. 16.7% p&lt;0.0106). The mean waiting time for a radiology department ultrasound is six days, 12 hours, and 16 minutes.Conclusion:Overall compliance is low, and delays to obtaining formal ultrasound are long. We observed that compliance rates for those who underwent bedside ultrasound were significantly higher than for those who did not. This suggests that bedside ultrasound is under-utilized in our ED. Training more staff to perform bedside scans would alleviate current delays to ultrasound diagnosis and reduce risks associated with empiric anticoagulation.

Use of Bedside Ultrasound at Wexford General Hospital Emergency Department: Compliance to NICE Guidelines [NG158] for Venous Thromboembolic Disease

Introduction:Ultrasound is the standard imaging technique for diagnosing lower limb deep venous thrombosis (DVT). The National Institute for Health and Care Excellence (NICE) guidance 158 recommendation 1.1.3 states that all patients with sufficient pretest probability for DVT should be offered a proximal leg vein ultrasound within four hours. However, due to high patient volumes, formal radiology department ultrasound wait times often exceed one week. Point-of-care ultrasound (POCUS) is used to bridge diagnostic delay in our emergency department (ED) .This study aimed to quantify numbers offered POCUS for suspected proximal lower DVT in our ED and accuracy of such studies.Method:A retrospective review of electronic records was conducted for patients who underwent formal lower-limb ultrasound for suspected DVT at our hospital over a three-month period (August 1, 2022-October 12, 2022). Patient charts for all ED presentations were assessed to determine whether POCUS was offered and whether DVT was diagnosed.Statistical analysis was conducted using PRISM v9.Results:80 formal ultrasound scans were performed at our hospital for lower limb DVT. 58 were requested for patients presenting to ED, of which 42 had complete records available meeting selection criteria.POCUS was offered to 24 patients in ED (57.1%). Sensitivity was 66% (95% CI 12%- 98%), and specificity was 94.1% (95% CI 75%-99%). Overall accuracy was 90%, with only one false negative study identified at formal follow-up ultrasound.Conclusion:Although sample size was small, our results suggest that POCUS is an accurate but underused tool to diagnose lower limb DVT. Developing a standardized protocol for performing and reporting POCUS DVT scans in ED should allow for earlier diagnosis and initiation of appropriate treatment where necessary.

The situation of pre-hospital care on emergency in hanoi through traumatic patients have been treated at Dong Da General Hospital in 2022

Introductions: Pre-hospital care, especially for severe trauma which contributes to reduce the risk of morbidities and mortalities. We conducted a study for having an over view of the situation of pre-hospital emergency in Hanoi city through traumatic patients have been treated at Dong Da General Hospital, one of the second level hospitals in Hanoi. Materials and methods: All traumatic patients have been admitted at the emergency department of Dong Da General Hospital during the period from March 2022 to October 2022, regardless of gender, age, had complete medical records, and including severe cases were discharged to die or dead in hospital. Data were collected by Epidata 3.1 and processed using SPSS 20.0 software. Results: Characteristics of target population: A total of 236 cases of traumatic patients were enrolled, of them, the ISS scores in the mild range accounted for the majority of 97.0%; Lesion located in limbs and pelvis accounts for the largest proportion of 43.1%. Current situation of pre-hospital care: Patients who did not receive first aid before coming to the hospital accounted for 71.6%, the first aid people were mainly accompanied by the person next to patient at the scene (65.7%). Transportation by ambulance accounts for only 1.7%, the average waiting time was 4.54 7.68 minutes. Patients receiving first aid to step Disability (D) accounted for the largest proportion with 59.7%, 34.3% of patients received first aid to step Exposure (E). Wound washing and bandaging are the two most commonly used techniques, accounting for 28.6%, with 1 patient requiring CPR accounting for 1.0%. Conclusions and recommendations: Through the study of pre-hospital care for trauma showed that most patients were initially managed by the person accompanying the patient. A low percentage of ambulance transportation can be potentially high risk for the patient. We recommend strengthening the network of collaborators and communities for pre-hospital care in emergency.

Evaluating the Evidence for Brain-Based Biotypes of Psychiatric Vulnerability in the Acute Aftermath of Trauma.

The weak link between subjective symptom-based diagnostic methods for posttraumatic psychopathology and objectively measured neurobiological indices forms a barrier to the development of effective personalized treatments. To overcome this problem, recent studies have aimed to stratify psychiatric disorders by identifying consistent subgroups based on objective neural markers. Along these lines, a promising 2021 study by Stevens et al. identified distinct brain-based biotypes associated with different longitudinal patterns of posttraumatic symptoms. Here, the authors conducted a conceptual nonexact replication of that study using a comparable data set from a multimodal longitudinal study of recent trauma survivors. A total of 130 participants (mean age, 33.61 years, SD=11.21; 48% women) admitted to a general hospital emergency department following trauma exposure underwent demographic, clinical, and neuroimaging assessments 1, 6, and 14 months after trauma. All analyses followed the pipeline outlined in the original study and were conducted in collaboration with its authors. Task-based functional MRI conducted 1 month posttrauma was used to identify four clusters of individuals based on profiles of neural activity reflecting threat and reward reactivity. These clusters were not identical to the previously identified brain-based biotypes and were not associated with prospective symptoms of posttraumatic psychopathology. Overall, these findings suggest that the original brain-based biotypes of trauma resilience and psychopathology may not generalize to other populations. Thus, caution is warranted when attempting to define subtypes of psychiatric vulnerability using neural indices before treatment implications can be fully realized. Additional replication studies are needed to identify more stable and generalizable neuroimaging-based biotypes of posttraumatic psychopathology.

How do factors in fixed clinical teams affect informal learning among Emergency Medicine Residents

Introduction: This study was performed to understand how fixed clinical teams affected informal learning in Emergency Medicine Residents. Better understanding the effects of team dynamics on informal learning may help to optimise learning and improve performance. Methods: From 8th February 2020 till 27th September 2020, the Singapore General Hospital Emergency Department adopted a fixed team system. Zoom interviews were carried out amongst Emergency Medicine Residents who worked in the fixed team system using a semi-structured iterative interview guide. A qualitative content analysis was used for this exploratory study. The interviews were transcribed verbatim, anonymised and coding via template analysis performed. Data collection and analysis were performed until data sufficiency. Results: The themes identified centred around relationship dynamics, team composition and motivation for learning. The first was how improved relationships led to improved trust, communications and camaraderie among team members. This improved peer learning and clinical supervision and provided a more personalised learning experience. A balanced team composition allowed learners to be exposed to experts in various subspecialties. Finally, there was an initial increase in motivation, followed by a decrease with time. Conclusion: In postgraduate medical education, working in a fixed team system with balanced members had positive effects on informal learning by strengthening relationships and communications.

Treatment Outcome and Associated Factors Among Patients Admitted with Hypertensive Crisis in Public Hospitals at Harar Town, Eastern Ethiopia: A Cross-Sectional Study.

Hypertensive crisis is a significant global health issue that raises the costs to healthcare systems and requires specific attention to improve clinical outcome. There is scarce information on hypertensive crisis cases treatment outcome in the study setting. This study aimed to assess treatment outcome and associated factors among patients admitted with hypertensive crisis at Public Hospitals in Harar Town, Eastern Ethiopia. A cross-sectional study was conducted among 369 hypertensive crisis patients who had been admitted to the emergency department of Hiwot Fana Comprehensive Specialized Hospital and Jugol General Hospital from May 1, 2017, to May 1, 2022. All hypertensive crisis patients who fulfilled the inclusion criteria were included. The data were extracted from medical records using a data abstraction format. The collected data were analyzed using Statistical Package for Social Sciences version 22. Binary logistics regression model using bivariate and multivariable analysis with 95% confidence intervals and P-values were used to determine the association between variables. The medical records of 369 patients in total were reviewed. Of these, the medical records of 363 patients contained all the necessary information and were used in the study. More than half of the patients (238; 65.6%) were males. Among 363 patients admitted with hypertensive crisis, 98 (27.0%, 95% Confidence Interval (CI):22.5%-31.9%) of them had poor treatment outcome of hypertensive crisis. Being female (Adjusted Odds Ratio (AOR)=3.4; 95% CI=1.7-7.9), residing in rural areas (AOR=2.4; 95% CI=2.7-5.1), taking captopril during admission (AOR=5.6; 95% CI=2.4-7.9), taking antihypertensive treatment before admission (AOR=0.5; 95% CI=0.2-0.9), and being non compliant to treatment (AOR=2.7; 95% CI=1.4-3.5) had statistically significant associations with poor treatment outcome of hypertensive crisis compared to their counterparts. The magnitude of poor treatment outcome of hypertensive crisis was high. Sex, residence, non-compliance, and type of emergency drug administered during admission were substantially related with poor treatment outcome of hypertensive crisis. Health professionals should put great emphasis on emergency drugs administered during admission to achieve the desired outcome.

Characteristics of Pediatric Patient Transfers From General Emergency Departments in California From 2005 to 2018.

Each year, approximately 300,000 pediatric patients are transferred out of emergency departments (EDs). Emergency department transfers may not only provide a higher level of care but also incur increased resource use and cost. Our objective was to identify hospital characteristics and patient demographics and conditions associated with ED transfer as well as the trend of transfers over time. This was a retrospective cohort study of pediatric visits to EDs in California using the California Office of Statewide Health Planning and Development ED data set (2005-2018). Hospitals were categorized based on inpatient pediatric capabilities. Patients were characterized by demographics and Clinical Classifications Software diagnostic categories. Regression models were created to analyze likelihood of outcome of transfer compared with admission. Over the 14-year period, there were 38,117,422 pediatric visits to 364 EDs in California with a transfer rate of 1% to 2%. During this time, the overall proportion of pediatric transfers increased, whereas pediatric admissions decreased for all hospital types. Transfers were more likely in general hospitals without licensed pediatric beds (odds ratio [OR], 16.26; 95% confidence interval [CI], 15.87-16.67) and in general hospitals with licensed pediatric beds (OR, 3.54; 95% CI, 3.46-3.62) than in general hospitals with pediatric intensive care unit beds. Mental illness (OR, 61.00; 95% CI, 57.90-63.20), poisoning (OR, 11.78; 95% CI, 11.30-12.30), diseases of the circulatory system (OR, 6.13; 95% CI, 5.84-6.43), diseases of the nervous system (OR, 4.61; 95% CI, 4.46-4.76), and diseases of the blood and blood-forming organs (OR, 3.21; 95% CI, 3.62; 95% CI, 3.45-3.79) had increased odds of transfer. Emergency departments in general hospitals without pediatric intensive care units and patients' Clinical Classifications Software category were associated with increased likelihood of transfer. A higher proportion of patients with complex conditions are transferred than those with common conditions. General EDs may benefit from developing transfer processes and protocols for patients with complex medical conditions.

Creating a sustainable weekly interprofessional simulation for the emergency department (ED) clinicians

Simulation-based education has been shown to improve clinical practice [1]. It offers an environment whereby complex real world situations can safely be practised facilitating learning through immersion, reflection, and feedback [2].There has been an increasing awareness amongst the medical profession as to the importance of simulation, we therefore created a sustainable simulation programme for the multidisciplinary team (MDT) at the Horton General Hospital (HGH) Emergency Department (ED) – Oxford University Hospitals NHS Foundation Trust. Several simulations were designed involving trauma, airway management, and acute adult and acute paediatric presentations. The focus of the simulations was based on identifying errors due to human factors. The simulations were designed utilising feedback forms as well as analysing information from clinical incident forms. These provided a platform to understand areas of improvement and targeted scenarios were created. A weekly simulation programme was then created involving the ED MDT (doctors, nurses, allied healthcare professionals) as well as other specialities (Paediatrics, Trauma and Orthopaedics, Anaesthetics and Acute General Medicine). The session was run every week for 2 hours in the ED as an ‘in-situ’ educational activity to provide a higher level of fidelity and provide an immersive environment for the participants. These scenarios were then debriefed by senior members of the team including speciality registrars and consultants trained on debriefing and human factors. The debriefings involved the discussion of human factors pertaining to the simulations and were learner-led. The feedback from the MDT was grossly positive; nursing staff and healthcare professionals in particular felt more empowered after the sessions to raise concern. Feedback was collected using an online survey which was sent to the participants following the session. Feedback obtained from participants aided improvement of targeted learning points and therefore aided debriefing. Our simulation programme has been run over 18 months and has had excellent feedback. We continue to improve our simulations and increase the participant numbers through the use of video links for the sessions; thereby engaging a wider audience. This has been crucial throughout the pandemic due to various reasons (room constraints, staff isolation). 1. Al-Elq AH. Simulation-based medical teaching and learning.

Longitudinal volumetric evaluation of hippocampus and amygdala subregions in recent trauma survivors.

The hippocampus and the amygdala play a central role in post-traumatic stress disorder (PTSD) pathogenesis. While alternations in volumes of both regions have been consistently observed in individuals with PTSD, it remains unknown whether these reflect pre-trauma vulnerability traits or acquired post-trauma consequences of the disorder. Here, we conducted a longitudinal panel study of adult civilian trauma survivors admitted to a general hospital emergency department (ED). One hundred eligible participants (mean age = 32.97 ± 10.97, n = 56 females) completed both clinical interviews and structural MRI scans at 1-, 6-, and 14-months after ED admission (alias T1, T2, and T3). While all participants met PTSD diagnosis at T1, only n = 29 still met PTSD diagnosis at T3 (a "non-Remission" Group), while n = 71 did not (a "Remission" Group). Bayesian multilevel modeling analysis showed robust evidence for smaller right hippocampus volume (P+ of ~0.014) and moderate evidence for larger left amygdala volume (P+ of ~0.870) at T1 in the "non-Remission" group, compared to the "Remission" group. Subregion analysis further demonstrated robust evidence for smaller volume in the subiculum and right CA1 hippocampal subregions (P+ of ~0.021-0.046) in the "non-Remission" group. No time-dependent volumetric changes (T1 to T2 to T3) were observed across all participants or between groups. Results support the "vulnerability trait" hypothesis, suggesting that lower initial volumes of specific hippocampus subregions are associated with non-remitting PTSD. The stable volume of all hippocampal and amygdala subregions does not support the idea of consequential, progressive, stress-related atrophy during the first critical year following trauma exposure.
