Background: There is no ubiquitous definition of Emergency Department (ED) crowding and several indicators have been proposed to measure it. The National ED Overcrowding Study (NEDOCS) score is among the most popular, even though it has been severely criticised. We used the waiting time for the physician's initial assessment to evaluate the performance of the NEDOCS and proposed a new crowding indicator based on this objective measure.

Methods: To evaluate the NEDOCS, we used the 2022 data of all the Lombardy EDs and compared the distribution of waiting times across the five levels of the NEDOCS at ED arrival. To construct the new indicator, we estimated the centre-specific relationship between the total number of ED patients and the waiting time of those with minor or deferrable urgency. We defined seven classes of waiting times and calculated how many patients corresponded to an average waiting time in the classes. These centre-specific cutoffs were used to define the 7-level crowding indicator. The indicator was then compared to the NEDOCS score and validated on the first six months of 2023 data.

Results: Patients' waiting time did not increase at the increase of the NEDOCS score, suggesting the absence of a relationship between this score and the effect of ED crowding on the ED capacity of evaluating new patients. The indicator we propose is easy to estimate in real-time and based on centre-specific cutoffs, which depend on the volume of yearly accesses. We observed minimal agreement between the proposed indicator and the NEDOCS in most EDs, both in the development and validation datasets.

Conclusions: We proposed to quantify ED crowding using the waiting time for physician's initial assessment of patients with minor or deferrable urgency, which increases in crowding situations due to the prioritization of urgent patients. The centre-specific cutoffs avoid the problem of the heterogeneity of the volume of accesses and organization among EDs, while enabling a fair comparison between centres.

Background: Disaster responders are exposed to several physical and mental health risks. This study aimed to describe self-care strategies used by disaster responders after the earthquake in Syria and eastern Turkey in February 2023.

Methods: A study specific web-based questionnaire survey was used to collect quantitative and qualitative data according to a convergent mixed methods approach. Data from 252 disaster responders responding to the earthquakes in Turkey and Syria were analyzed using both descriptive and analytical statistics and summative content analysis of free-text answers. Data were collected in March to July, 2023.

Results: The most used self-care strategies included resting, social support from colleagues in the field, extra intake of food or drink, and intake of medicines. The recovery strategies varied due to previous disaster response experience, indicating that supportive self-care strategies can be developed or learned.

Conclusion: Given the extreme conditions and limited possibilities of external support, sufficient self-care is an essential competence among disaster responders. Self-care strategies can be both external processed such as intake of medicines, social support from others, and internal processes such as personal reflection. Providing oneself with self-care activities seems to be a skill developed with increasing experience supported by pre-deployment training. Therefore, to enhance resilience, self-care strategies should be encompassed in pre-disaster response training.

Background: The prevalence of emergency department (ED) visits among the elderly is high and increasing. While emergency services for the elderly involve many factors, drug-related problems (DRPs) that can worsen patient conditions are less frequently discussed. This study investigates the prevalence of preventable drug-related ED visits (DRED_p) and the characteristics of DRPs in elderly ED patients through a comprehensive medication review.

Methods: A cross-sectional study was conducted at a non-trauma ED of a university-affiliated tertiary-care hospital. All adult patients aged 60 years and older who were on medications and visited the ED were included. A clinical pharmacist conducted comprehensive medication reviews for each patient. Patients were classified as experiencing drug-related ED visits (DRED) if their primary reason for the visit was associated with a DRP, as determined by both the physician and pharmacist. DRPs attributed to medication errors were categorized as preventable, while other DRPs were assessed for preventability using modified Schumock and Thornton criteria.

Results: The study involved 351 patients with a mean age of 75.5 years (SD 9.3) and an equal male-to-female ratio of ED visits. The median number of comorbidities was five (IQR 3-6), with about half of the patients taking ten or more medications. The interdisciplinary team classified 43 patients (12.3%) as DRED_p, accounting for 58.1% of the 74 (21.1%) drug-related ED visits. All medication errors categorized as causing harm (level E and higher) occurred within the DRED_p group, constituting approximately half of all DRED_p (22 cases, 51.2%). Approximately two-thirds of drug-related ED visits were associated with adverse drug events (ADEs), predominantly involving antithrombotics, oral hypoglycemic agents, and antineoplastics. Multivariable analysis identified that ED visits involving potentially inappropriate medications (PIMs) according to the STOPP criteria and the presence of multiple comorbidities (six or more concurrent diseases) were significantly associated with DRED_p.

Conclusions: About one in ten elderly patients visited the ED due to preventable DRPs. The majority of DRPs leading to ED visits were ADEs. Both the prescription of PIMs and the presence of multiple comorbidities were significantly associated with DRED_p.

Background: Cameroon is amongst the worst affected countries by road traffic injuries with an estimated 1443 disability-adjusted life years per 100,000 population. There have been very limited reports on the crucial prehospital response to road traffic injuries in Cameroon. This study aimed to identify prehospital factors associated with RTI mortality in Cameroon.

Methods: We included patients enrolled between June 2022 and March 2023 in the Cameroon Trauma Registry. Information about prehospital factors and demographic data was obtained from patients or their proxies. We examined the association of prehospital care factors like care at the crash scene and type of transportation during crash with final patient outcome. We used Chi-squared test to investigate the association between selected independent variables and mortality. A multivariable logistic regression model was built to identify independent predictors of dying from an RTI.

Results: RTIs constituted 69.5% (n = 3203) of all injuries in the Cameroon Trauma Registry. Only 20.7% (n = 102) of 4 + wheel vehicle occupants had seatbelts on and just 2.7% (n = 53) of motorcycle riders were wearing helmets during the collision. Only 4.9% (n = 156) of patients received any form of scene care. In-hospital mortality was 4.3% (n = 139) and was associated with male sex (AOR = 1.7, 95%CI = 1.08-2.80), crashing on a motorcycle (AOR = 2.08, 95%CI = 1.1-3.67) and scene care (AOR = 0.25, 95%CI = 0.04-0.80).

Conclusions: Receiving any type of care at the scene such as bleeding control or being placed in the recovery position by bystanders is associated with improved survival. Improving on existing informal prehospital care responses should be a priority in Cameroon.

Purpose: During resuscitation in emergency situations, establishing intravascular access is crucial for promptly initiating delivery of fluids, blood, blood products, and medications. In cases of emergency, when intravenous (IV) access proves unsuccessful, intraosseous (IO) access serves as a viable alternative. However, there is a notable lack of information concerning the frequency and efficacy of IO access in acute care settings. This study aims to assess the efficacy of intraosseous (IO) access in acute care settings, especially focusing on children in a level 1 trauma center.

Methods: This retrospective study included patients with IO access presented in a level 1 trauma center emergency department (ED) between January 2015 and April 2020. Data regarding medication and fluid infusion was documented, and the clinical success rate was calculated.

Results: Of the 109,548 patients that were admitted to the ED, 25,686 IV lines were inserted. Documentation of 188 patients of which 73 (38.8%) children was complete and used for analysis. In these 188 patients, a total of 232 IO accesses were placed. Overall, 182 patients had a functional IO access (204 needles) (88%). In children (age < 18 years) success rate was lower as compared to adults, 71-84% as compared to 94%. However, univariate regression showed no association between the percentage of functional IO access and gender, age, weight, health care location (prehospital and in hospital), anatomical position (tibia as compared to humerus) or type of injury.

Conclusion: Intraosseous access demonstrates a high success rate for infusion, independent of gender, age, weight, anatomical positioning, or healthcare setting, with minimal complication rates. Caution is especially warranted for children under the age of six months, since success rate was lower.

Background: In modern emergency medical services (EMS), ambulances increasingly focus on examining and treating the patient at the scene. This has led to increased levels of non-conveyance. In Finland, for instance, approximately 40% of EMS dispatches end up in non-conveyance. As EMS systems evolve, the proportion of non-conveyance could serve as a cost-effective measure to assess the quality of the dispatch criteria, if a link to the performance of urgency assessment would be established. The purpose of this study was to investigate whether the proportion of non-conveyance is associated with the test performance levels of the urgency assessment. This investigation was done separately within each dispatch category.

Methods: A retrospective evaluation of the data was conducted on all EMS dispatches in the Pirkanmaa Hospital District from 1 August 2021 through 31 August 2021. There were a total of 7,245 EMS dispatches during the study period of which 829 were excluded. This study was conducted by comparing the existing test performance levels (sensitivity, specificity and under- or overestimation) of the emergency response centre's urgency assessment with the non-conveyance rate (%) of each dispatch category. The relationships between the variables were measured using Spearman's rank correlation coefficient.

Results: The proportion of over-triage was the only urgency assessment's test performance variable that had a statistically significant correlation with the proportion of non-conveyance (r = 0.568; p = 0.003). Other test performance variables of the urgency assessment had no or little correlation to the proportion of non-conveyance. Of the 6,416 EMS dispatches in the study period, 42% (2,672) resulted in non-conveyance of the patient. In nine dispatch categories, at least half (51-69%) of the dispatches ended in non-conveyance.

Conclusions: Based on this study, it seems that the percentage of non-conveyance in the dispatch category could be used, with certain limitations, to assess the proportion of over-triage in the dispatch category. The method is particularly applicable in scenarios where the dispatch criteria have undergone modifications and there is a need to monitor the effect of the changes on the level of over-triage.

Background: A frequent caller is defined by The Frequent Caller National Network (FreCaNN) as an adult who makes five or more emergency calls in a month or twelve or more in three months, related to individual episodes of care. However, we believe that when limiting the definition to those who call themselves, one underestimates the impact frequent contacts have on the Emergency Medical Communication Center (EMCC) and the Emergency Medical Services (EMS).

Method: We conducted a descriptive retrospective cross-sectional database review of frequent contacts; defined as persons who have ≥ 5 contacts in a month or ≥ 12 contacts in three months. Data were provided from Oslo EMCC, between 1. January 2017 and 31. December 2022. Contrary to the FreCaNN definition, we included all types of contacts and callers, both emergent and non-emergent, regarding patients of all ages.

Results: During the study period, 2.149.400 contacts were registered. Of these 129.700 were contacts from frequent callers, where the patients called themselves. When including contacts frequently made on behalf of a patient, we found that 268.723 fit the definition of frequent emergency contacts. When also taking non-emergent contacts into account, a total of 437.361 contacts fit the definition of frequent contacts.

Conclusion: When limiting the criteria to only frequent callers, one underestimates the impact persons who have frequent contacts, have on the EMCC and the EMS. We were able to distinguish between three categories-contacts from frequent callers, frequent emergency contacts, and frequent contacts. We believe broadening the definition can benefit both research and audits, when accessing the use of emergency resources to patients with frequent requests for help to the EMCCs.

Background: The aim of this systematic review was to investigate how clinical prediction models compare in terms of their methodological development, validation, and predictive capabilities, for patients with blunt chest trauma presenting to the Emergency Department.

Methods: A systematic review was conducted across databases from 1st Jan 2000 until 1st April 2024. Studies were categorised into three types of multivariable prediction research and data extracted regarding methodological issues and the predictive capabilities of each model. Risk of bias and applicability were assessed.

Results: 41 studies were included that discussed 22 different models. The most commonly observed study design was a single-centre, retrospective, chart review. The most widely externally validated clinical prediction models with moderate to good discrimination were the Thoracic Trauma Severity Score and the STUMBL Score.

Discussion: This review demonstrates that the predictive ability of some of the existing clinical prediction models is acceptable, but high risk of bias and lack of subsequent external validation limits the extensive application of the models. The Thoracic Trauma Severity Score and STUMBL Score demonstrate better predictive accuracy in both development and external validation studies than the other models, but require recalibration and / or update and evaluation of their clinical and cost effectiveness.

Background: In patients presenting to the emergency department (ED) with acute respiratory failure, non-invasive mechanical ventilation (NIMV) is applied when conventional oxygen support is not sufficient. Patients who are agitated often have very low NIMV compliance and a transition to invasive mechanical ventilation (IMV) is often required. To avoid IMV, a suitable sedative agent can be utilized. The aim of this research is to investigate the relationship between ketamine administration to patients who are non-compliant with NIMV due to agitation and the outcome of their intubation.

Methods: This retrospective study included patients with acute respiratory failure who were admitted to the ED from 2021 to 2022 and used Richmond Agitation Sedation Scale (RASS) to identify agitation level of patients. The relationship between ketamine administration in this patient group and NIMV compliance and intubation rate was evaluated.

Results: A total of 81 patients, including 35 (43.2%) men and 46 (56.8%) women, were included in the study. Of these patients, 46 (56.8%) were intubated despite ketamine administration, while 35 (43.2%) were compliant with NIMV and were not intubated. When evaluating the RASS, which shows the agitation levels of the patients, the non-intubated group was found to be 2.17 ± 0.68, while the intubated group was 2.66 ± 0.73, and it was statistically significant that the NIMV intubated group was higher (p = 0.003).

Conclusion: This study showed that agitation can impair NIMV compliance in patients with acute respiratory failure. However, a significant proportion of this patient group can be avoided through IMV with proper sedative agents.
