Background: Accurate triage is required for efficient allocation of resources and to decrease patients' length of stay. Triage decisions are often subjective and vary by provider, leading to patients being over-triaged or under-triaged. This study developed machine learning models that incorporated natural language processing (NLP) to predict patient disposition. The models were assessed by comparing their performance with the judgements of emergency physicians (EPs).

Method: This retrospective study obtained data from patients visiting EDs between January 2018 and December 2019. Internal validation data came from China Medical University Hospital (CMUH), while external validation data were obtained from Asia University Hospital (AUH). Nontrauma patients aged ≥ 20 years were included. The models were trained using structured data and unstructured data (free-text notes) processed by NLP. The primary outcome was death in the ED or admission to the intensive care unit, and the secondary outcome was either admission to a general ward or transferal to another hospital. Six machine learning models (CatBoost, Light Gradient Boosting Machine, Logistic Regression, Random Forest, Extremely Randomized Trees, and Gradient Boosting) and one Logistic Regression derived from triage level were developed and evaluated using EPs' predictions as reference.

Result: A total of 17,2101 and 41,883 patients were enrolled from CMUH and AUH, respectively. EPs achieved F1 core of 0.361 and 0.498 for the primary and secondary outcomes, respectively. All machine learning models achieved higher F1 scores compared to EPs and Logistic Regression derived from triage level. Random Forest was selected for further evaluation and fine-tuning, because of its robust calibration and predictive performance. In internal validation, it achieved Brier scores of 0.072 and 0.089 for the primary and secondary outcomes, respectively, and 0.076 and 0.095 in external validation. Further analysis revealed that incorporating unstructured data significantly enhanced the model's performance. Threshold adjustments were applied to improve clinical applicability, aiming to balance the trade-off between sensitivity and positive predictive value.

Conclusion: This study developed and validated machine learning models that integrate structured and unstructured triage data to predict patient dispositions, distinguishing between general ward and critical conditions like ICU admissions and ED deaths. Integrating both structured and unstructured data significantly improved model performance.

Background: Road traffic injuries are a global public health challenge. This study was conducted to describe the epidemiological patterns of road traffic injuries in a large tertiary care hospital in the West Bank of Palestine. In addition, associations between the different variables of the victims and the patterns of road traffic injuries were also assessed.

Methods: This study was conducted in a retrospective cohort observational design between January 2021 and July 2023 at a large tertiary care hospital in Nablus, Palestine. The data were collected from the electronic medical record system of the large tertiary care hospital using a data collection form.

Results: A total of 1,544 victims of traffic road injuries were included in this study. Lower limb (43.0%), neck (41.2), and upper limb (39.8%) injuries were the most common types of road traffic injuries sustained by the victims admitted to the large tertiary care hospital. The victims who were 30 years or older were more likely to sustain back injuries (aOR = 1.71, 95% CI: 1.20-2.45) pelvic injuries (aOR = 1.84, 95% CI: 1.08-3.12), chest injuries (aOR = 1.59, 95% CI: 1.06-2.38), and neck injuries (aOR = 2.54, 95% CI: 1.68-3.82) compared to the victims who were younger than 30 years. The victims who did not use seatbelts were more likely to sustain abdominal injuries (aOR = 1.88, 95% CI: 1.34-2.63) and head injuries (aOR = 1.49, 95% CI: 1.06-2.10) compared to the victims who used seatbelts. The victims who did not have the airbag deployed were more likely (aOR = 1.85, 95% CI: 1.31-2.63) to sustain neck injuries compared to the victims who had the airbag deployed.

Conclusion: The epidemiological patterns of road traffic injuries in a large tertiary care hospital in Nablus, Palestine were described and the associations between the different variables of the victims and the patterns of road traffic injuries were assessed. The findings indicated a need to design measures to prevent/minimize these injuries. Future studies are still needed to determine the best measures to avoid/minimize the incidence of serious road traffic injuries.

Objective: Studies have shown that Emergency Department physicians have little to no training in recognizing and supporting victims of human trafficking despite being uniquely situated to identify and intervene on behalf of these patients. We assessed if screening for human trafficking was being completed by emergency physicians in three Saskatoon emergency departments.

Methods: We performed a retrospective chart review of patients presenting to three Saskatoon emergency departments deemed to potentially be at risk of human trafficking, based on discharge diagnosis. Of the 223 included charts, data extracted included sex, age, ethnicity, chief complaint, diagnosis, disposition, HT Screening (Y/N), specific quotes relating to HT, time of visit, intimate partner violence (Y/N), and travel history. Both quantitative and qualitative thematic analyses were conducted on this data.

Results: None of the charts (0%) included in this study had any documentation around screening for human trafficking. Furthermore, 21.1% of the high-risk patient charts included in this study -- which included many patients with a discharge diagnosis of sexually transmitted disease or pelvic inflammatory disease -- did not contain a documented sexual history. Thematic analysis revealed that the patients included in this study frequently had challenges with sexual health, substance use, and houselessness.

Conclusion: This study found that Emergency physicians in Saskatoon were not routinely screening for human trafficking. Implementation of further training is needed to help these physicians recognize and subsequently support potential victims of human trafficking.

Background: Saudi paramedics face numerous challenges while providing care for adult trauma patients affecting their care but little is known about these specific challenges.

Methods: A qualitative study was conducted using a purposive sample of Saudi paramedics from the Saudi Red Crescent Authority (SRCA) across various cities. Data were collected through online semi-structured interviews and analyzed using the framework method.

Results: A total of 20 paramedics were recruited and interviewed. They identified challenges in trauma response, including coordinating care, ensuring the accuracy and accessibility of patient information, and maintaining confidence and readiness. Participants emphasized the need for independent knowledge acquisition through courses, simulations, and peer discussions. They also highlighted the need for more paramedics, strategies to reduce burnout, and the importance of accurately assessing patient conditions. Additionally, they also stressed the importance of raising public awareness to enhance trauma care.

Conclusion: This study explored Saudi paramedics' experiences in managing adult trauma patients. standardized handovers, more staff, and greater public awareness are the main key needs to improve daily practice.

Objective: The aim of this study was to describe perceived health problems among disaster responders after the earthquake in eastern Turkey/Syria in February 2023.

Methods: A non-probability cross-sectional study was conducted using an online survey.

Results: A total of 525 local (18%) and international disaster responders (81%) participated in the study. Of these responders, 46% reported physical or mental health problems during or after their deployment, 15% required medical care during the mission, and 7% required medical evacuation. The most common health problems during the field mission were feeling scared or unsafe, sleeping problems, and headache. After the mission, fatigue, sleeping problems, and feeling depressed were the most frequently reported health problems. The local responders perceived significantly more health problems than did the international responders. Approximately 11% of the participants could not return to their ordinary work after deployment because of infections or mental health issues.

Conclusions: Physical and mental health problems are commonly perceived by disaster responders and may reduce the effectiveness of disaster response. Raising awareness of health risks among disaster response workers and employers is essential to ensure proper duty of care and should include reparations and medical support during and after disaster response operations.

Background & objectives: The increasing proportion of elderly populations has led to a rise in chronic diseases and frequent transfers between long-term care hospitals (LTCHs) and emergency departments (EDs). This study investigates the patterns of risk factors of initial-transfers and subsequent re-transfers among patients aged 65 or older. Specifically, we focus on those re-transferred from LTCHs to EDs within 48 h of discharge, often without adequate treatment.

Method: This nationwide cross-sectional study used data from South Korea's National Emergency Department Information System (NEDIS) from January 1, 2017, to December 31, 2019. Patients aged 65 or older who were initially transferred from LTCHs to EDs and re-transferred within 48 h, were identified. Logistic regression was employed to analyze risk factors associated with re-transfers.

Results: 140,282 elderly patients were identified as having been transferred from LTCHs to EDs. Of these, 38,180 patients received emergency care in the EDs and were discharged back to LTCHs. Among them, 679 patients were returned to LTCHs after receiving acute treatment but revisited the EDs within 48 h. Hospital ward admission rates were higher for re-transferred patients (71.3%) compared to initial transfers (42.1%, p < 0.0001). Risk factors for re-transfer included male, nighttime admissions, and longer ED stays (> 6 h). Tertiary hospitals showed higher re-transfer rates to other facilities (13.1%) than general hospitals (2.9%).

Conclusion: This study reveals that many health outcomes worsen upon re-transfer compared to the initial-transfer. These findings underscore the need for a coordinated healthcare system that ensures elderly patients from long-term care facilities are initially sent to appropriate hospitals during the initial transfer, which could mitigate repeated ED visits and ensure timely care.

Background: The reduction of processing times in the treatment of acute ischemic stroke is of outstanding importance. Our objective is to analyze the acute stroke care chain from onset to treatment in a city in Germany comprising three stroke units. Additionally, we discuss solutions for detected treatment delays.

Methods: We conducted an in-depth analysis of acute stroke care processing times across three local stroke centers in Düsseldorf among all emergency services transportations for suspected stroke. Isochrone mapping was performed to identify areas with prolonged transportation times.

Results: Among the 1,714 transportations, 943 patients had confirmed strokes. Prehospital care constituted 58% of total emergency care time until imaging. Patients with confirmed stroke had reduced in-hospital times while patients receiving treatment experienced faster in-hospital times. Isochrone mapping revealed disparities in transportation times within the city.

Conclusions: In conclusion, we identified confirmation of stroke symptoms as pre- and in-hospital and treatment eligibility as in-hospital process accelerators in stroke care. We propose the introduction of an in-ambulance video consulting model to accelerate contact to stroke-experts and accelerate processing times for patients eligible for treatment. Furthermore, we discuss the combination of in-ambulance video consulting with imaging and starting treatment outside traditional stroke centers, followed by transportation to a stroke center during thrombolysis, which might further accelerate treatment in specific cases.

Background: Chest pain is a common condition in the emergency department (ED). High-sensitivity cardiac troponin (hs-cTn) assays are crucial for diagnosing acute coronary syndrome, but the implications of "negative but measurable" hs-cTn levels are not well understood. This study assesses the outcomes of patients with acute chest pain discharged from the ED based on their hs-cTn levels.

Methods: This retrospective cohort study analyzed medical records of patients aged 18 and older presenting with chest pain to the Tel Aviv Sourasky Medical Center ED from 2017 to 2022. We compared patients with negative but measurable hs-cTn levels (3-50 ng/L) to those with very low hs-cTn levels (< 3 ng/L). Primary outcomes included 90- days coronary angiogram (CAG), and secondary outcomes were 7- days ED revisits, 14-days hospital admissions, and 30- days mortality.

Results: Of 32,162 eligible patients, 23,297 had hs-cTn levels ≤ 50 ng/L. Patients with negative but measurable hs-cTn levels had higher rates of 90-days CAG (1.8% vs. 0.5%, p < 0.001), 7-day ED revisits (5.2% vs. 3.3%, p < 0.001), 14-day hospital admissions (3.1% vs. 0.9%, p < 0.001), and 30-day mortality (0.3% vs. 0.01%, p < 0.001) compared to those with very low hs-cTn levels. Independent predictors for 90 days CAG included age ≥ 57 years, male sex, and hs-cTn ≥ 3.5 ng/L.

Conclusions: Negative but measurable hs-cTn levels are linked to worse outcomes than very low hs-cTn levels in discharged ED patients. Closer follow-up and further cardiac evaluation may be warranted for these patients.

Background: In healthcare facilities, an efficient triage system is critical to optimize patient care. The main objective of this study was to explore the triage processes and practices in three different tiers of healthcare facilities in the Kathmandu Valley, Nepal.

Methods: A mixed-methods approach in this study comprised observations and interviews in ten healthcare settings across primary care centers (PHC; n = 6), secondary care centers (SHC; n = 3), and tertiary care hospital (n = 1). Data were collected from June to November 2023. Semi-structured interviews were conducted among patients (n = 30) including survey questionnaires among 144 healthcare workers (HCWs) focused on triage. The qualitative data were analyzed using Interpretative Phenomenological Analysis and quantitative data were analyzed to explore the median score on the consistent practice of triage based on the Likert scale.

Results: PHCs had designated space for triage with less equipped emergency services and outpatient departments (OPDs) and received severely ill patients rarely. Although prioritizing critical patients and prompt care was part of the services, there was a lack of triage protocols with more than half of the HCWs (56.3%; 36/64) from the tertiary hospital reporting the availability of triage guidelines compared to SHCs (28.1%; 9/32) and PHCs (6.3%; 3/48). The majority of HCWs from the tertiary level recognized triage's effectiveness in reducing time lag, and prioritizing patients. Tertiary level had the consistent use of triage (94%; 60/64) compared to only around two-thirds in SHCs (66%; 19/29) and PHCs (62%; 28/45). Patients often attended PHC services for routine check-ups and were motivated by health insurance, affordability, free medicines, referral cards, and proximity. In the SHC, there was a well-equipped emergency department (ED) with specific guidelines, but its use was infrequent. Patients were unaware of the triage process and its utility. In all settings, while most HCWs had a basic knowledge of triage, some were not confident due to limited exposure to the triage process and training. Many HCWs reported the need for triage-related training and its' consistent implementation.

Conclusions: Consistent utilization of triage protocols, coupled with improved infrastructure, resource allocation, and training for healthcare workers is critical for the optimization of triage processes in healthcare settings in the Kathmandu Valley, Nepal.

Background: The high incidence of airway management failure in the emergency department (ED) necessitates a comparative analysis of laryngoscopy methods. This study aims to compare the success and complications associated with video-assisted laryngoscopy (VL) and direct laryngoscopy (DL) in emergency tracheal intubation in ED.

Methods: This retrospective cohort study was conducted at the ED of Thammasat University Hospital. It involved adult patients undergoing emergency tracheal intubation using either VL (GlideScope^®) or DL (Macintosh^®). The outcomes assessed were success rates of intubation and occurrence of peri-intubation adverse events. Propensity score matching and multivariable risk regression analysis were employed for statistical evaluation.

Results: The study included 3,424 patients, with 342 in the VL group and 3,082 in the DL group. The initial analysis revealed no significant differences in the intubation success rates between the two methods. However, the VL group experienced fewer peri-intubation adverse events (33% compared to 40%). After propensity score matching, a higher first-attempt success rate was observed in the DL group (88.9% vs. 81.3%, risk difference: 7.6, 95% CI: 1.9 to 13.2, p=0.009), but there was no statistically significant difference in peri-intubation adverse events. VL had a lower first-attempt success rate among low-experience intubators. Subgroup analyses of intubators with moderate and high experience, as well as patients who received both induction agents and neuromuscular blocking agents, show results consistent with the analysis of the entire cohort.

Conclusion: Both VL and DL have comparable first-attempt success rates and peri-intubation adverse events. VL is particularly beneficial when used by moderately or highly experienced intubator. The choice of intubation method, combined with clinical experience and technique plays a critical role in the success and safety of emergency intubations.
