Background: Non-life-threatening cases treated by emergency services have been increasing in recent years, especially in older people. In a region in Germany with approximately 600,000 inhabitants, the role of a specially trained community paramedic (Gemeindenotfallsanitäter, G-NFS) was introduced in 2019. The G-NFS is dispatched to low-acuity requests, attends the assignment alone and is allowed to treat patients at home.

Aim: The aim of this study was to analyse the assignments attended by the G-NFS relating to the suspected diagnoses, with a focus on older people (≥ 65 years) according to their care setting.

Methods: In this descriptive, retrospective study, we analysed the anonymous assignment report forms 07/2023-12/2023 of cases where patients were aged ≥ 65 years. The suspected diagnoses (free text field) were categorised according to the International Classification of Primary Care 2nd Edition (ICPC-2) scheme. Furthermore, baseline characteristics, urgency of the assignment, provided measures, transport and further treatment were analysed, stratified by care setting.

Results: Of the 1,643 included anonymous assignment report forms, 52.9% (n = 869) related to patients aged ≥ 65 years. In this population, the mean age was 80.7 years (SD 8.2), 49.6% were female and most were in long-term care, whether as home care recipients (34.8%) or as nursing home residents (26.9%). The most frequent diagnoses were categorised as urological (24.9%), general and unspecified (13.7%), circulatory (13.6%), digestive (12.8%), musculoskeletal (11.5%) and respiratory (10.3%). In 52.7% of the cases no transport was necessary, while 73.7% of urological cases did not need to be transported.

Conclusion: The G-NFS was dispatched mainly to older people. Most of them were in long-term care and were not transported. The most common suspected diagnoses were categorised as urological, followed by general and unspecified, and circulatory, and differed by care setting. There is a strong need to strengthen outpatient healthcare structures for low-acuity health issues in older and immobile patients.

Objectives: Emergency Medical Communication Centers (EMCC) have a key role in the prehospital chain-of-stroke-survival by recognizing stroke patients and reducing prehospital delay. However, studies on EMCC stroke recognition report both substantial undertriage and overtriage. Since mis-triage at the EMCC challenges the whole chain-of-stroke-survival, by occupying limited resources for non-stroke patients or failing to recognize the true stroke patients, there is a need to achieve a more comprehensive understanding of the dispatchers' routines and experiences. The aim of this study was to explore factors affecting EMCC dispatcher's decision-making in stroke calls.

Materials and methods: A qualitative exploratory study, based on individual semi-structured interviews of 15 medical dispatchers from EMCC Oslo, Norway. Interviews were conducted during August and October 2022 and analyzed using the principles of thematic analysis.

Results: We identified four themes: [1] Pronounced stroke symptoms are easy to identify [2]. Non-specific neurological symptoms raise suspicion of acute stroke but are difficult to differentiate from other medical conditions [3]. Consistent use of the Criteria Based Dispatch (CBD) protocol may increase EMCC overtriage [4]. Contextual conditions at EMCC can affect dispatchers' decision-making process and the ability for experiential learning.

Conclusions: Medical dispatchers at the EMCC perceive vague and non-specific stroke symptoms, such as dizziness, confusion or altered behaviour, challenging to differentiate from symptoms of other less time-critical medical conditions. They also perceive the current CBD protocol in use as less supportive in assessing such symptoms. High workload and strict EMCC response time interval requirements hinder the gathering of essential patient information and the ability to seek guidance in cases of doubt, potentially exacerbating both EMCC undertriage and overtriage. The absence of feedback loops and other strategies for experiential learning in the EMCC hampers the medical dispatcher's ability to evaluate their own assessments and improve dispatch accuracy.

Background: The duration between a patient's arrival at the Emergency Department (ED) and their actual departure, known as the Emergency Department Length of Stay (EDLOS), can have significant implications for a patient's health. In Ethiopia, various studies have investigated EDLOS, but a comprehensive nationwide pooled prevalence of prolonged EDLOS, which varies across different locations, is currently lacking. Therefore, the objective of this systematic review and meta-analysis is to provide nationally representative pooled prevalence of prolonged EDLOS and identify associated factors.

Methods: In this study, we conducted a comprehensive systematic review and meta-analysis using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 checklist. We conducted a thorough search of numerous international databases, including PubMed/Medline, SCOPUS, Web of Science, and Google Scholar. The primary outcome was the prevalence of prolonged EDLOS. The secondary outcome was factors affecting the EDLOS. Random-effects model was used to since there was high heterogeneity. We also conducted subgroup analysis and meta-regression to investigate heterogeneity within the included studies. To assess publication bias, we used Egger's regression test and funnel plots. All statistical analyses were performed using STATA version 17.0 software to ensure accurate and reliable findings.

Result: We have identified eight articles that met our inclusion criteria with a total sample size of 8,612 participants. The findings of this systematic review and meta-analysis indicate that the pooled estimate for the prevalence of prolonged EDLOS is 63.67% (95% CI = 45.18, 82.16, I² = 99.56%, P = 0.0001). The study identified several significant factors associated with prolonged EDLOS, including patients admitted to overcrowded emergency departments (OR = 5.25, 95% CI = 1.77, 15.58), delays in receiving laboratory findings (OR = 3.12, 95% CI = 2.16, 4.49), and delays in receiving radiological results (OR = 3.00, 95% CI = 2.16, 4.16).

Conclusion: In this review, the EDLOS was found to be very high. Overcrowding, delays in laboratory test findings, and delays in radiology test results make up the factors that have a statistically significant association with prolonged EDLOS. Given the high prevalence of prolonged EDLOS in this review, stakeholders should work to increase the timeliness of ED services in Ethiopia by proper disposition of non-emergency palliative patients to the appropriate destination, and implementing point-of-care testing and imaging.

Background: The emergency medical service (EMS) addresses all chief complaints across all ages in various contexts. Children in EMS present a particular challenge due to their unique anatomical and physical properties, which require specific training that EMS clinicians often report lacking. This combination exposes children to incidents threatening patient safety. The most common method to highlight incidents is the incident reporting system. Studies have shown underreporting of such incidents, highlighting the need for multiple methods to measure and enhance patient safety in EMS for children. Thus, the aim of this study was to modify and adapt the current Ambulance TT for road-based EMS (ATT) to a pediatric version (pATT) with a guide containing definitions of triggers.

Methods: The adaption of the ambulance trigger tool to a version suitable for children followed a stepwise manner, including (1) a review of previous literature to pinpoint areas of risk regarding patient safety among children in EMS. (2) Three sessions of expert panel discussions via video meetings were held to evaluate each trigger of the ATT in terms of clinical relevance, comprehensibility, language and areas of risk regarding patient safety among children in EMS. (3) Clinical use of the pATT along with Retrospective Record Review (RRR). (4) Calculation of Item-level validity index and positive predictive value (PPV) for each trigger. (5) calculate inter-rater reliability between two independent record reviewers.

Results: The literature search revealed 422 respective 561 articles in Cinahl and Medline where headlines and abstracts were read to identify areas posing risks to patient safety in EMS for children. During the structured discussions, one trigger was added to the existing 19 derived from the ATT, and the trigger definitions were modified to suit children. The three most common triggers identified in the 900 randomly selected records were deviation from treatment guidelines (63.9%), incomplete documentation (48.3%), and the patient is non conveyed after EMS assessment (41.1%). The positive triggers were categorized into near miss (54.6%), no harm incident (5.8%), and harmful incident (0.4%). Inter-rater reliability testing showed excellent agreement.

Conclusion: This study demonstrates the adaptation of an existing trigger tool (ATT) to one suitable for children. It also shows that the trigger tool, along with retrospective record review, is a feasible method to evaluate patient safety in EMS, thus complementing existing methods.

Background: Ambulance missions involving pediatric patients are common in emergency medical services (EMS) globally, with variations in prevalence based on geographic location. This retrospective cohort study analyzes the prehospital physician staffed units (p-EMS) in Stockholm, assignment dispatches and the prehospital characteristics and interventions involved, from January 1, 2021, to December 31, 2022.

Methods: Utilizing data from LogEze, a quality assurance system, we reviewed all Rapid Response Vehicle (RRV) operations in the Stockholm Region, which totaled 4,682 pediatric assignments. The analysis included dispatch types and interventions assessing the frequency and nature of pediatric prehospital missions.

Results: Pediatric cases constituted 20.0 % of RRV dispatches, with the majority involving respiratory distress, seizures, and blunt trauma. Despite high dispatch rates, advanced medical interventions were seldom required, indicating most pediatric cases were not severe. Stand-downs occurred in 30.1 % of cases, reflecting the cautious approach in pediatric dispatches. Furthermore, the study observed a significant reliance on p-EMS for complex pediatric cases, underscoring the value of specialized training and resources in managing such emergencies.

Conclusion: The study highlights the crucial role of p-EMS in enhancing pediatric emergency care in Stockholm. Despite frequent pediatric dispatches, the low incidence of severe cases underscores the need for precise triage and resource allocation. This analysis supports the need for continuous training and resource optimization in p-EMS to ensure high-quality care for pediatric patients across varied emergency scenarios.

Background: Acute diverticulitis is commonly misdiagnosed among patients with acute abdominal pain in the emergency department (ED). There are predictive scores that assist in the diagnosis of acute left-sided diverticulitis, but no scoring system is available for diagnosing acute diverticulitis without regard to the affected side. Therefore, developing a predictive score for diagnosing acute diverticulitis that is not limited to the left side will guide physicians in making a diagnosis and increase the appropriateness of computed tomography. This study aimed to establish a predictive score for diagnosing acute diverticulitis.

Method: This single-centre retrospective study included adult patients (≥ 18 years) who presented to the ED with acute abdominal pain. Multivariate logistic regression analysis was used to identify essential factors for diagnosing acute diverticulitis, and the Akaike information criterion was calculated to identify significant predictive factors for diagnosing acute diverticulitis using a clinical scoring system.

Results: Of 424 patients who fulfilled the inclusion criteria, 72 (17%) were diagnosed with acute diverticulitis. The significant factors associated with acute diverticulitis were age ≥ 60 years (adjusted odds ratio (adj.OR) 2.23, 95% confidence interval (CI): 1.20 - 4.14, p = 0.01), duration of abdominal pain ≥ 48 h (adj.OR 2.64, 95% CI: 1.28 - 5.45, p = 0.017), history of a diverticulum (adj.OR 7.77, 95% CI: 3.27 - 18.45, p < 0.001), absence of nausea and vomiting (adj.OR 3.42, 95% CI: 1.65 - 7.10, p < 0.001), absence of anorexia (adj.OR 3.33, 95% CI: 1.34 - 8.33, p = 0.026), absence of tachycardia (adj.OR 3.51, 95% CI: 1.39 - 8.87, p = 0.003), and abdominal guarding (adj.OR 2.99, 95% CI: 1.52 - 5.91, p = 0.002). These predictive factors were converted into predictive scores for diagnosing acute diverticulitis. For the score of ≥ 4, the sensitivity and specificity were 73.24% (95% CI: 0.61-0.83) and 80.40% (95% CI: 0.76-0.84), respectively, and the negative predictive value was 93.71% (95% CI: 0.90-0.96). No significant signs, symptoms, or laboratory findings were associated with complicated diverticulitis.

Conclusion: Predictive factors for diagnosing acute diverticulitis included age ≥ 60 years, duration of abdominal pain ≥ 48 h, history of a diverticulum, abdominal guarding, and absence of nausea and vomiting, anorexia, and tachycardia. A predictive score ≥ 4 suggested the presence of acute diverticulitis.

Background: Adverse events occur frequently at emergency departments (ED) because of several risk factors related to varying conditions. It is still unclear, which factors lead to patient safety incident reports. The aim of this study was to explore the root causes behind ED-associated patient safety incidents reported by personnel, and based on the findings, to suggest learning objectives for improving patient safety.

Methods: The study material included incident reports (n = 340) which concerned the ED of a teaching hospital over one year. We used a mixed method combining quantitative descriptive statistics and qualitative research by inductive content analysis and deductive Ishikawa root cause analysis.

Results: Most (76.5%) incidents were reported after patient transfer from the ED. Nurses reported 70% of incidents and physicians 7.4%. Of the reports, 40% were related to information flow or management. Incidents were evaluated as no harm (29.4%), mild (46%), moderate (19.7%), and severe (1.2%) harm to the patient. The main consequences for the organization were reputation loss (44.1%) and extra work (38.9%). In the qualitative analysis, nine specific problem groups were found: insufficient introduction, adherence to guidelines and protocols, insufficient human resources, deficient professional skills, medication management deficiencies, incomplete information transfer from the ED, language proficiency, unprofessional behaviour, identification error, and patient-dependent problems. Six organizational themes were identified: medical staff orientation, onboarding and competence requirements; human resources; electronic medical records and information transfer; medication documentation system; interprofessional collaboration; resources for specific patient groups such as geriatric, mental health, and patients with substance abuse disorder. Entirely human factor-related themes could not be defined because their associations with system factors were complex and multifaceted. Individual and organizational learning objectives were addressed, such as adherence to the proper use of instructions and adequate onboarding.

Conclusions: System factors caused most of the patient safety incidents reported concerning ED. The introduction and training of ED -processes is elementary, as is multiprofessional collaboration. More research is needed about teamwork skills, patients with special needs and non-critical patients, and the reporting of severe incidents.

Aim: Relatives of patients who have experienced an out of hospital cardiac arrest (OHCA) experience confusion and distress during resuscitation. Clear information from ambulance clinicians and the opportunity to witness the resuscitation helps them navigate the chaotic scene. However, UK-based evidence concerning relatives' experiences of unsuccessful resuscitation attempts and interactions with ambulance clinicians is lacking. This qualitative study explores those experiences to inform ambulance clinician practice.

Methods: Two ambulance services in the UK identified OHCA events attended by their clinicians within the previous two weeks. After a minimum of three months relatives of non-survivors of these events were invited to participate in either a remote or face-to-face interview. Interviews focussed on their experiences of the resuscitation attempt and interactions with ambulance clinicians, their feelings at the time, and their reflections on the event afterwards. Data were analysed using reflexive thematic analysis.

Results: Semi-structured interviews were conducted with 14 relatives of OHCA non-survivors. Thematic analysis identified four themes. Cardiac arrest is a traumatic event for relatives, with chaotic noisy scenes increasing their distress. Many described feelings symptomatic of Post-Traumatic Stress Disorder since the event. During resuscitation, participants needed information from clinicians about what was happening, and provided information about their relatives' wishes. Participants needed reassurance from clinicians that everything possible was done to save their relative and were reassured when they could witness some of the resuscitation. Participants were surprised how long resuscitation seemed to last; some were distressed that it lasted so long.

Conclusion: Relatives' experiences highlight two key challenges for ambulance clinicians: (1) being aware of the tension relatives feel between needing reassurance that the crew is doing everything to save the patient and wanting to avoid prolonged and ultimately futile resuscitation attempts; and (2) having ongoing conversations with those present to inform clinical decision-making whilst managing the resuscitation attempt.

Background: Head injuries are the leading cause of trauma in Emergency Departments (EDs). Recent studies have shown epidemiological changes in patients consulting ED for head injuries. The main objective of this study was to describe the profile of head injury patients consulting in the EDs in France and assess i) head injury severity across age groups; ii) the delay between the occurrence of head injury and ED arrival; iii) factors associated with traumatic intracranial hemorrhage (ICH).

Methods: This cross-sectional study collected patient data over a three-day period in March 2023. All adult patients (≥ 18 years old) admitted to the ED with a head injury (defined as a trauma to the head) were included. TBI severity was classified according to patients' initial Glasgow Coma Scale score in the ED: severe (3-8); moderate (9 -12); mild (13-15); and simple head trauma in the absence of transient or persistent neurological symptoms.

Results: Among the 71 participating EDs, 26,008 patients visited EDs and a total of 1070 patients (4.1%, IC 95 3.9-4.4) presented a head injury were included in the study, with a median age of 68.5 [37-85] years old. Most of the patients (66.7%) were referred to ED after a call to the Emergency Medical Dispatcher (EMD). The median time from head injury to ED visit was 2 h [1.0 - 5.5]. Ground-level falls were the leading cause of head injury (60.3%). Most of patient presented a simple head trauma (n = 715, 66.8%) followed by mild TBI (n = 337, 31.5%). CT head scans were performed for 636 patients (59.6%), of which 58 were positive. Traumatic ICH prevalence was 5.4% (95% CI: 4.1-6.9) and three patients (0.3%) required an urgent neurosurgical intervention. Neither preinjury anticoagulant (p = 0.97) nor antiplatelet (p = 0.93) use was associated with an increased risk of traumatic ICH.

Conclusions: One head injury patient out of two presenting in the ED is aged over 65 years. Patients referred by EMD were more likely to visit ED promptly. The majority of older patients underwent a head CT scan and preinjury anticoagulant use was not associated with increased risk of traumatic ICH.

Background: On October 7, 2023, Hamas carried out an unprecedented attack on the State of Israel and kidnapped 251 people into captivity to the Gaza Strip. Several months later, as part of a humanitarian exchange deal, 105 hostages were released in five phases and admitted to one of six hospitals throughout the country for treatment. Shamir Medical Center (SMC) was one of these facilities. This study aims to describe the structure, process and outcomes of establishing a comprehensive, multi-step, operational protocol for receiving hostages returning from captivity.

Method: The process of preparing SMC as a receiving center, the establishment of procedures for implementation of the medical protocol, and the assessment of multi-disciplinary team preparedness and implementation and outcomes in an institutional protocol are described.

Results: 24 returning hostages were received at SMC. Social workers, dietitians and translators were used by 100% of the majority group of returning hostages from the same country of origin and the sole individual from the other country of origin utilized a dietitian, social worker, ENT consultations, and a hearing test. Among the majority group, orthopedic and dermatological consultations were utilized by 17.4% and 13% received an ENT consultation. Of the administered imaging, 13% received a chest X-ray, 8.7% received a limb X-ray, 17.4% received a head CT scan, and 4.3% received an abdominal CT. In addition, 21.7% were provided antibiotic therapy. Protocol efficacy was measured by assessing time to various operational aspects of protocol implementation and medical procedures such as mean hours to room assignment, primary physician evaluation and social worker session. No correlation between age and operational variables was found.

Conclusion: This novel operational protocol was successfully implemented and may serve as a framework for managing similar unpredictable sensitive events in the case of future need.
