Evaluating the impact of artificial intelligence-assisted image analysis on the diagnostic accuracy of front-line clinicians in detecting fractures on plain X-rays (FRACT-AI): protocol for a prospective observational study.

INTRODUCTION: Missed fractures are the most frequent diagnostic error attributed to clinicians in UK emergency departments and a significant cause of patient morbidity. Recently, advances in computer vision have led to artificial intelligence (AI)-enhanced model developments, which can support clinicians in the detection of fractures. Previous research has shown these models to have promising effects on diagnostic performance, but their impact on the diagnostic accuracy of clinicians in the National Health Service (NHS) setting has not yet been fully evaluated. METHODS AND ANALYSIS: A dataset of 500 plain radiographs derived from Oxford University Hospitals (OUH) NHS Foundation Trust will be collated to include all bones except the skull, facial bones and cervical spine. The dataset will be split evenly between radiographs showing one or more fractures and those without. The reference ground truth for each image will be established through independent review by two senior musculoskeletal radiologists. A third senior radiologist will resolve disagreements between two primary radiologists. The dataset will be analysed by a commercially available AI tool, BoneView (Gleamer, Paris, France), and its accuracy for detecting fractures will be determined with reference to the ground truth diagnosis. We will undertake a multiple case multiple reader study in which clinicians interpret all images without AI support, then repeat the process with access to AI algorithm output following a 4-week washout. 18 clinicians will be recruited as readers from four hospitals in England, from six distinct clinical groups, each with three levels of seniority (early-stage, mid-stage and later-stage career). Changes in the accuracy, confidence and speed of reporting will be compared with and without AI support. Readers will use a secure web-based DICOM (Digital Imaging and Communications in Medicine) viewer (www.raiqc.com), allowing radiograph viewing and abnormality identification. Pooled analyses will be reported for overall reader performance as well as for subgroups including clinical role, level of seniority, pathological finding and difficulty of image. ETHICS AND DISSEMINATION: The study has been approved by the UK Healthcare Research Authority (IRAS 310995, approved on 13 December 2022). The use of anonymised retrospective radiographs has been authorised by OUH NHS Foundation Trust. The results will be presented at relevant conferences and published in a peer-reviewed journal. TRIAL REGISTRATION NUMBERS: This study is registered with ISRCTN (ISRCTN19562541) and ClinicalTrials.gov (NCT06130397). The paper reports the results of a substudy of STEDI2 (Simulation Training for Emergency Department Imaging Phase 2).

Safety-netting strategies for primary and emergency care: a codesign study with patients, carers and clinicians in Sweden.

OBJECTIVES: To codesign safety-netting strategies for primary and emergency care settings by integrating the experiences and ideas of patients, carers and clinicians. DESIGN: A codesign process involving two focus group discussions, eight individual interviews and five workshops. All sessions were audio recorded and transcribed verbatim. Data were analysed using qualitative content analysis and reported using the Consolidated criteria for Reporting Qualitative research guidelines. SETTING: Primary and emergency care in Sweden, focusing on the Stockholm region. PARTICIPANTS: 7 (5 women) individuals with patient expertise, 1 (man) individual with carer expertise, 18 (12 women) individuals with clinical expertise. RESULTS: Three main categories reflecting strategies for applying safety-netting were developed: first, conveying safety-netting advice, which involves understanding patient concerns, tailoring communication and using appropriate modalities for communicating; second, ensuring common understanding, which involves summarising information, asking a teach-back question and anticipating questions post consultation; and third, supporting safety-netting behaviour, which involves facilitating reconsultation, helping patients and carers to navigate the health system and explaining the care context and its purpose. CONCLUSIONS: Our study highlights the collaborative nature of safety-netting, engaging both the clinician and patient, sometimes supported by carers, in an iterative process. Adding to previous research, our study also emphasises the importance of anticipating postconsultation inquiries and facilitating reconsultation.

Barriers and facilitators to implementing psychosocial digital health interventions for older adults presenting to emergency departments: a scoping review protocol.

INTRODUCTION: Older adults can face challenges when seeking care from emergency departments (EDs) due to presenting with multiple comorbidities and non-specific symptoms. Psychosocial care is a possible target to help improve ED care for this population. It is possible that digital health technologies can be implemented within emergency settings to improve the provision of psychosocial care. However, it is unclear what the barriers and facilitators are to implementing digital psychosocial interventions for older adults presenting to the ED. Therefore, the scoping review aims to determine what are these barriers and facilitators. METHODS AND ANALYSIS: The scoping review will be conducted in line with the Joanna Briggs Institute guidelines and will use the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist. The databases Medline, Embase, PsycINFO and Scopus will be searched. The search strategy will be developed in consultation with a specialist research librarian and will cover three key concepts: EDs, digital health technologies and older adults. Additionally, the first 100 hits of a Google Scholar search will be screened for inclusion. We will include both qualitative and quantitative studies that investigate ED digital interventions for psychosocial care where the primary focus is the views, attitudes, experiences and perceptions of patients, families and staff. After extracting all data, analysis and synthesis will follow the 'best-fit framework synthesis' approach and the Theoretical Domains Framework will be used to identify barriers and facilitators. ETHICS AND DISSEMINATION: Ethics approval is not required for this scoping review since only publicly available data will be analysed and appraised. The findings of the scoping review will be disseminated through peer-reviewed publications and conference presentations.

Midwives' and registered nurses' role and scope of practice in acute early pregnancy care settings in Australia: A qualitative descriptive study.

PROBLEM: There is little documented evidence regarding the practice of midwives providing care for women with acute concerns in early pregnancy (< 20 weeks) in Australia. BACKGROUND: Women can experience unexpected complications at any gestation of pregnancy and may seek acute care in an emergency or gynaecology service, usually staffed by registered nurses (RNs). They may not receive care from specialised pregnancy clinicians, including midwives. The role and scope of practice of midwives working in acute early pregnancy settings in Australia has not been previously reported. This study provides an opportunity to document practice in an area of pregnancy care not often visible within maternity services in Australia. RESEARCH AIM: To describe midwives' and RNs perceptions, perspectives and experiences of role and scope of practice in acute early pregnancy care provision in Australia. METHODS: A qualitative descriptive approach was adopted. Midwives and RNs with acute early pregnancy knowledge and experience were recruited. Semi-structured interviews were conducted, and data analysed using inductive thematic analysis. FINDINGS: Fifteen participants were interviewed. Three themes were constructed from interview data: Personal and Professional Influences; Being There for Women; The Impact of Setting. DISCUSSION: Findings reinforce the lack of clarity around how midwives' scope is enabled in traditional acute early pregnancy care. Setting of care has influenced practice and seen a barrier for midwives who don't hold nursing registration from fulfilling professional scope. Results provide novel benchmarking evidence regarding a largely hidden area of midwifery, signposting areas for reform within education, policy and health service sectors.

[For an institutional outreach approach in emergency medical services]. / Développer une culture institutionnelle de l'« aller vers ¼ dans les Samu.

FOR AN INSTITUTIONAL OUTREACH APPROACH IN EMERGENCY MEDICAL SERVICES. The "outreach" approach has become the new paradigm of social action. With the creation of regional health agencies, the decompartmentalization between curative medicine, preventive medicine and medico-social care is accelerating. The political will to transpose social tools to the medical field requires removing the confusion between the logic of "outreach" (of Samusocial) and "outside the walls" (of Samu). Especially since Samu, as interface organizations, are privileged hospital actors for this decompartmentalization. The approach initiated by the pediatric Samu of Paris shows that this transposition is possible, both at the individual and institutional levels.

DÉVELOPPER UNE CULTURE INSTITUTIONNELLE DE L'« ALLER VERS ¼ DANS LES SAMU. La démarche de l'« aller vers ¼ est devenue le nouveau paradigme de l'action sociale. Avec la création des agences régionales de santé, le décloisonnement entre médecine curative, médecine préventive et prise en charge médico-sociale s'accélère. La volonté politique de transposer les outils du social au champ médical nécessite de lever la confusion entre les logiques de l'« aller vers ¼ (du Samu social) et du « hors les murs ¼ (du Samu). D'autant que les Samu, en tant qu'organisations d'interface, sont des acteurs hospitaliers privilégiés pour ce décloisonnement. La démarche initiée par le Samu pédiatrique de Paris montre que cette transposition est possible, aussi bien au niveau individuel qu'au niveau institutionnel.

Diagnostic accuracy of a prehospital electrocardiogram rule-based algorithm for ST-elevation myocardial infarction: results from a population-wide project.

INTRODUCTION: This study reviewed the diagnostic accuracy of the prehospital electrocardiogram (PHECG) rule-based algorithm for ST-elevation myocardial infarction (STEMI) universally utilised in Hong Kong. METHODS: This prospective observational study was linked to a population-wide project. We analysed 2210 PHECGs performed on patients who presented to the emergency medical service (EMS) with chest pain from 1 October to 31 December 2021. The diagnostic accuracy of the adopted rulebased algorithm, the Hannover Electrocardiogram System, was evaluated using the adjudicated blinded rating by two investigators as the primary reference standard. Diagnostic accuracy was also evaluated using the attending emergency physician's diagnosis and the diagnosis on hospital discharge as secondary reference standards. RESULTS: The prevalence of STEMI was 5.1% (95% confidence interval [CI]=4.2%-6.1%). Using the adjudicated blinded rating by investigators as the reference standard, the rule-based PHECG algorithm had a sensitivity of 94.6% (95% CI=88.2%-97.8%), specificity of 87.9% (95% CI=86.4%-89.2%), positive predictive value of 29.4% (95% CI=24.8%-34.4%), and negative predictive value of 99.7% (95% CI=99.3%-99.9%) [all P<0.05]. CONCLUSION: The rule-based PHECG algorithm that is widely used in Hong Kong demonstrated high sensitivity and fair specificity for the diagnosis of STEMI.

Intravenous ketamine for emergency department treatment of suicidal ideation in a paediatric population: protocol for a double-blind, randomised, placebo-controlled, parallel-arm pilot trial (KSI study).

INTRODUCTION: Suicidal ideation (SI) is a common and severe cause of morbidity in adolescents. Patients frequently present to the emergency department (ED) for care, yet there is no acute therapeutic intervention for SI. A single dose of intravenous ketamine has demonstrated efficacy in rapidly reducing SI in adults; however, ketamine has not been studied in paediatrics. We aim to determine the feasibility of a trial of a single intravenous ketamine dose to reduce SI for patients in the paediatric ED. METHODS AND ANALYSIS: This will be a single-centre, double-blind, randomised, placebo-controlled, parallel-arm pilot trial of intravenous ketamine for ED treatment of SI in a paediatric population. INTERVENTION: one intravenous dose of 0.5 mg/kg of ketamine (max 50 mg), over 40 min. Placebo: one intravenous dose of 0.5 mL/kg (max 50 mL) of normal saline, over 40 min. Participants will be randomised in a 1:1 ratio. SI severity will be measured at baseline, 40 min, 80 min, 120 min, 24 hours and 7 days. We aim to recruit 20 participants. The primary feasibility outcome is the proportion of eligible patients who complete the study protocol. We will pilot three SI severity tools and explore the efficacy, safety and tolerability of the intervention. ETHICS AND DISSEMINATION: This study will be conducted according to Canadian Biomedical Research Tutorial, international standards of Good Clinical Practice and the Health Canada, Food and Drug Act, Part C, Division 5. The study documents have been approved by the CHEO Research Institute Research Ethics Board (CHEO REB (23/02E)). Participants must provide free and informed consent to participate. If incapable due to age, assenting participants with parental/legal guardian consent may participate. On completion, we will endeavour to present results at international conferences, and publish the results in a peer-reviewed journal. Participants will receive a results letter. TRIAL REGISTRATION NUMBER: NCT05468840.

Pathology requesting in a regional Australian Emergency Department; an observational study comparing current practice with college guidelines.

INTRODUCTION: In 2018, the Australasian College for Emergency Medicine (ACEM) and the Royal College of Pathologists of Australasia (RCPA) produced a guideline to encourage appropriate pathology requesting in the Emergency Department (ED). OBJECTIVE: To assess adherence to the ACEM/RCPA pathology testing guideline in a regional ED. METHODS, DESIGN, SETTING AND PARTICIPANTS: This was a retrospective observational study conducted at a regional Australian ED over 7 days. Adults with a presenting complaint encompassed by the guideline were included. All blood tests were audited against the guideline recommendations and classified as indicated or non-indicated. Chi-squared analyses were performed to explore the association between presenting complaint and non-indicated testing. MAIN OUTCOME MEASURE: The primary outcome was the number of non-indicated blood tests. RESULTS: Forty percent of tests ordered were not clinically indicated, with non-indicated testing occurring during 87% of encounters. The C-reactive protein (CRP) was the test most frequently ordered outside of guidelines (94% non-indicated). Patients presenting with lower abdominal pain accounted for nearly one-quarter of all non-indicated tests. CONCLUSIONS: Blood tests were commonly requested outside of the guideline recommendations and interventions to improve pathology stewardship are required.

Mapping the processes and information flows of a prehospital emergency care system in Rwanda: a process mapping exercise.

OBJECTIVE: A vital component of a prehospital emergency care system is getting an injured patient to the right hospital at the right time. Process and information flow mapping are recognised methods to show where efficiencies can be made. We aimed to understand the process and information flows used by the prehospital emergency service in transporting community emergencies in Rwanda in order to identify areas for improvement. DESIGN: Two facilitated process/information mapping workshops were conducted. Process maps were produced in real time during discussions and shared with participants for their agreement. They were further validated by field observations. SETTING: The study took place in two prehospital care settings serving predominantly rural and predominantly urban patients. PARTICIPANTS: 24 healthcare professionals from various cadres. Field observations were done on 49 emergencies across both sites. RESULTS: Two maps were produced, and four main process stages were described: (1) call triage by the dispatch/call centre team, (2) scene triage by the ambulance team, (3) patient monitoring by the ambulance team on the way to the health facility and (4) handover process at the health facility. The first key finding was that the rural site had multiple points of entry into the system for emergency patients, whereas the urban system had one point of entry (the national emergency number); processes were otherwise similar between sites. The second was that although large amounts of information were collected to inform decision-making about which health facility to transfer patients to, participants found it challenging to articulate the intellectual process by which they used this to make decisions; guidelines were not used for decision-making. DISCUSSION: We have identified several areas of the prehospital care processes where there can be efficiencies. To make efficiencies in the decision-making process and produce a standard approach for all patients will require protocolising care pathways.

'I've got to go in there with my armour on': Adverse Childhood Experiences Among Adults Who Frequently Attend Emergency Departments.

Frequent presentations to emergency departments contribute to increased service demands and healthcare costs. Literature suggests these adult presentations may be influenced by childhood adversity. This qualitatively driven, mixed methods study explored the self-perceived role of childhood adversity in the health of adults who frequently attended Australian Emergency Departments and their perceptions of the healthcare they received. Data were collected using validated instruments and semi-structured interviews with 12 purposefully sampled adults who frequently attended emergency departments. Qualitative data were analysed using interpretive phenomenological analysis. Three major themes were identified-The experience of childhood adversity: articulating challenges related to childhood trauma, and the subsequent impacts on participants' health, behaviours, relationships and sense of control; Pursuing safety: exploring action participants took to keep themselves and others safe, with this requirement extending into adulthood and influencing Emergency Department presentations; and Seeking humanising healthcare: identifying challenges participants experienced while seeking care in the Emergency Department. Participants perceived their mental health to be profoundly affected by their past experiences of trauma, leaving them feeling vulnerable at times and more likely to experience re-traumatisation in the Emergency Department. Feelings of stigmatisation during Emergency Department encounters led participants to employ self-protection strategies creating further barriers to recovery. Participants described Emergency Departments as often failing to comprehensively address their healthcare needs. They offered suggestions for more effective care interventions. Findings highlight the need for further research to inform policy and practice when designing and implementing interventions for these adults. Consolidated Criteria for Reporting Qualitative Research (COREQ) guided study reporting.

Emergency department staff experiences of working with people who self-harm: A qualitative examination of barriers to optimal care.

For people who seek help for self-harm, emergency departments (ED) are often the first point of contact, making them a suitable setting for intervention. In Australia, base rates of self-harm presentations to ED are increasing, while the quality of care these people receive is often considered sub-optimal. This study used qualitative interviews to explore potential barriers ED staff face in delivering best possible self-harm care. Seventeen staff across two EDs in the state of Victoria, Australia, were interviewed regarding their perceptions of barriers to providing optimal self-harm care and suggestions for improvement. Three themes were identified: (1) system-related challenges when managing self-harm in ED, including the shortage of hospital resources, challenges of ED as a physical environment, and insufficient education, training and guidelines about self-harm care for staff; (2) human-related challenges regarding management of self-harm in ED, which encompassed the nature of a person's circumstances and presentation, and staff attitudes towards self-harm; and (3) staff suggestions for improving self-harm care in ED. Specific recommendations that were proposed based on these findings included introducing a separate ED area for mental health-related presentations, provision of specialised education and training about self-harm care to staff, better implementation of guidelines on treating self-harm in ED, and employing mental health educators to provide on-the-floor mentoring to nurses. The relevance of these barriers and recommendations to the wider healthcare sector is also discussed. Together, these findings may inform improvements to the quality of care provided to those who engage in self-harm.

The 4AT scale for rapid detection of delirium in emergency department triage.

Aims: To assess the diagnostic accuracy and time impact of the 4AT scale in emergency department triage. Methods: A Prospective diagnostic accuracy study was carried out. People aged ≥65 years presenting to the emergency department from 1 November 2021 to 30 June 2022 were included. Nurses opportunistically screened eligible patients using the 4AT scale during triage according to the Manchester Triage System Francesc de Borja Hospital emergency department, Gandía (Spain). Accuracy was compared with medical diagnosis of delirium. Time (seconds) spent in triage with and without screening was assessed. Results: The study included 370 patients (55.1% men, mean age 81.8 years), of whom 58.4% (n = 216) were screened. A final diagnosis of delirium was made in 41.4% of those screened. The most frequently used presentational flow charts and discriminators were 'behaving strangely' (15%) and 'rapid onset' (33.3%). The highest accuracy was obtained for a score of 3 points or more (sensitivity 85.1%; specificity 66.9%; positive predictive value 52.8%; negative predictive value 71.7%). No significant differences were found in the time spent in triage according to the performance of screening. Conclusion: A score of 3 points or more on the 4AT scale enables rapid detection of delirium in emergency department triage, without consuming more time than conventional triage.

Does moral distress in emergency department nurses contribute to intentions to leave their post, specialisation, or profession: A systematic review.

Background: There is a global shortfall of nurses. Despite national targets to increase nurse training and retention, the numbers leaving the profession continue to rise. Emergency departments (EDs) consistently record above average staff-turnover. Meanwhile descriptions of moral distress amongst emergency nurses are increasing. It is vital to consider the long-term emotional and psychological impact of moral distress on the emergency nursing workforce. However, the events which trigger moral distress in the emergency department may differ from those described in other clinical areas. A clearer understanding of the effects of moral distress on intention to leave could help identify those at risk and inform decisions on interventions designed to mitigate moral distress, aiding nurse retention and the organisational stability of health services. Aim: This systematic review aims to synthesise the available evidence on the association between moral distress and intention to leave in emergency nurses. Methods: A systematic search of studies was performed on MEDLINE, CINAHL, PsychINFO, Web of Science and Cochrane databases (8th -10th June 2022). Results were screened and quality-assessed with cross-checks. The heterogeneity of samples and insufficient data precluded statistical pooling and meta-analysis. Consequently, narrative synthesis was performed. Results: Five studies reported quantitative results eligible for synthesis. Low to moderate levels of moral distress were reported in emergency nurses; contrasting starkly with the significant proportion who reported having left or considered leaving due to moral distress (up to 51%). Sparse, mostly low-quality evidence was identified, highlighting a need for more robust research. Current tools for measuring moral distress appear not to capture the unique pressures which contribute to moral distress in emergency nurses. Conclusions: Emergency nurses cite moral distress as a reason for leaving. Further study is required to determine the levels of moral distress associated with intentions to leave and the strength of that association. This is fundamental to the design of effective retention policies. Future research should also explore the applicability of current moral distress measures to the emergency department, with consideration given to developing emergency department specific tools.

Post-lockdown burden of road injury involving hospitalisation in Victoria, Australia: A statewide, population-based time series analysis.

OBJECTIVES: Ever since COVID-19, short-term changes in transport injury patterns have been observed. The aim is to examine both the initial and the enduring impact of government lockdown and the pandemic on road injuries requiring hospitalisation and road fatalities. METHODS: Time series analysis of Transport Accident Commission (TAC) claims involving hospitalisation and fatalities in Victoria, Australia, from July 2016 to May 2023, including lockdown (March 2020 to October 2020) and post-lockdown (November 2020 onwards). RESULTS: A total of 46 450 TAC claims were included. Average claims during the pre-pandemic period were 652/month. Lockdown restrictions were associated with a statistically significant fall in monthly claims (-255, 95% confidence interval [CI] = -315 to -194, P < 0.01). This was consistent across road users, days of the week, hours of the day, injury severity, sex and central versus rural locations. The post-lockdown period had a statistically significant reduction in monthly claims to 76% (95% CI = 67-84) of pre-pandemic levels (-158, 95% CI = -213 to -102, P <0.01). This was consistent across all subgroups except bicyclist injuries, which remained constant (-8, 95% CI = -16 to 0, P = 0.05). There was a significant upward trend in the fatality-to-claim ratio post-lockdown (0.001, 95% CI = 0-0.001, P <0.01). CONCLUSION: Road injury requiring hospitalisation decreased significantly during governmental lockdown and has returned to three-quarters of pre-pandemic levels (except bicyclist injuries that have remained constant), but there is an increasingly disproportionate number of fatalities. This represents a new baseline of injury burden for EDs and hospitals that manage trauma patients.

Childhood opportunity and appropriate use of child safety restraints in motor vehicle collisions.

Objectives: Safety restraints reduce injuries from motor vehicle collisions (MVCs) but are often improperly applied or not used. The Childhood Opportunity Index (COI) reflects social determinants of health and its study in pediatric trauma is limited. We hypothesized that MVC patients from low-opportunity neighborhoods are less likely to be appropriately restrained. Methods: A retrospective cross-sectional study was performed on children/adolescents ≤18 years old in MVCs between January 1, 2011 and December 31, 2021. Patients were identified from the Children's Hospital Los Angeles trauma registry. The outcome was safety restraint use (appropriately restrained, not appropriately restrained). COI levels by home zip codes were stratified as very low, low, moderate, high, and very high. Multivariable regression controlling for age identified factors associated with safety restraint use. Results: Of 337 patients, 73.9% were appropriately restrained and 26.1% were not appropriately restrained. Compared with appropriately restrained patients, more not appropriately restrained patients were from low-COI (26.1% vs 20.9%), high-COI (14.8% vs 10.8%) and very high-COI (10.2% vs 3.6%) neighborhoods. Multivariable analysis demonstrated no significant associations in appropriate restraint use and COI. There was a non-significant trend that children/adolescents from moderate-COI neighborhoods were more likely than those from very low-COI neighborhoods to be appropriately restrained (OR=1.82, 95% CI 0.78, 4.28). Conclusion: Injury prevention initiatives focused on safety restraints should target families of children from all neighborhood types. Level of evidence: III.

Comparison of clinical outcomes of venous thromboembolic disease between outpatient and inpatient management.

Objectives: To compare the occurrence of death, bleeding, and recurrence according to inpatient or outpatient management of venous thromboembolic disease (VTE). Materials and methods: . Retrospective cohort that included a consecutive sampling of VTE consultations between 2016 and 2019 diagnosed in the Emergency Center of a private hospital in Argentina. Results: There were 1202 cases, 908 with isolated deep vein thrombosis (DVT), 205 with isolated pulmonary embolism (PE), and 89 cases of combined DVT - PE. 66% were women, with a median age of 77 years; 72% of cases were managed on an outpatient basis (n= 862). Comorbidities associated with hospitalization were obesity (p=0.03), chronic obstructive pulmonary disease (COPD) (p=0.01), heart failure (CHF) (p=0.01), chronic renal failure (CKD) (p=0.01), and cancer (p=0.01). At 90 days, the cumulative incidence of bleeding was 2.6% in inpatient compared to 2.9% in outpatient management (p=0.81); recurrence was 0% versus 0.9% (p=0.07), and mortality was 42.9% versus 18.9%, respectively (p=0.01). The HR for 90-day mortality in hospitalized patients adjusted for confounders (sex, age, type of VTE, obesity, CKD, CHF, COPD, and cancer) was 1.99 (95% CI 1.49-2.64; p=0.01). Conclusions: In this elderly, and predominantly female Argentine population, the 90-day mortality in patients hospitalized for VTE was higher than mortality in patients with outpatient management, without differences in recurrence or major bleeding.

Cooperación entre médicos del departamento de emergencias y dermatólogos por telemedicina / Cooperation between emergency department physicians and dermatologists via telemedicine

Las intercurrencias dermatológicas agudas son un motivo de consulta frecuente a las centrales de emergencias, y generalmente los médicos de atención primaria se ocupan del primer nivel de atención. Puede ser necesaria una interconsulta con expertos, aunque no siempre estén disponibles. Ante la necesidad de facilitar dicha interacción a distancia, en Julio 2022 se implementó una herramienta de teledermatología en un hospital de alta complejidad en Buenos Aires, Argentina. Este servicio se limitó a días hábiles con horario restringido, permitiendo la comunicación entre médicos del departamento de emergencias y dermatólogos, a través de WhatsApp institucional. El dermatólogo podía verificar datos de salud relacionados al paciente (ej: comorbilidades y medicación crónica) mediante revisión de la historia clínica electrónica, para decidir sobre un plan de acción. Se evaluó la perspectiva de los usuarios a través de un formulario electrónico tras 3 meses de implementación. Los resultados evidenciaron que la mayoría (85%) de los profesionales conocía la herramienta, y el 57% la había usado al menos una vez. Se obtuvo una mediana de 9 puntos (de una escala de Likert del 1 al 10) sobre la recomendación hacia otro profesional. El teletriage dermatológico resultó beneficioso y fue aceptado, tanto por médicos de guardia como por especialistas. Ante las demoras en la atención ambulatoria, ha resultado una alternativa útil para evitar derivaciones innecesarias y/o acelerar aquellas que verdaderamente lo ameritan. Sin embargo, representa una forma de comunicación informal desde el punto de vista de almacenamiento de datos. Será necesario reflexionar sobre estos tópicos pendientes de esta experiencia asistencial como legalidad, seguridad y confidencialidad (AU)

Acute skin conditions are a frequent reason for consultation in emergency departments, and primary care physicians generally handle them. They might require referrals to experts, who are not always readily available. Recognizing the need to facilitate such interactions remotely, a teledermatology triage tool was implemented in July 2022 at a high-complexity hospital in Buenos Aires, Argentina. The service was limited to business days with restricted hours, enabling communication between emergency department physicians and dermatologists through institutional WhatsApp. Dermatologists could access patient-related health data (e.g., comorbidities and chronic medication) through the electronic medical record to determine an appropriate course of action. The perspective of users was evaluated through an electronic questionnaire after three months of application. Results showed that most professionals were aware of the tool (85%), and 57% used it at least once. The median rating for recommending the tool to other professionals was 9 points (on a Likert scale from 1 to 10). Dermatological teletriage proved beneficial and was well-received by emergency physicians and specialists. In the face of delays in outpatient care, it has been a useful alternative to avoid unnecessary referrals and expedite those that are warranted. However, it represents an informal method of communication with regard to data storage. It will be necessary to rethink on improvements in pending topics such as legal limitations, security, and confidentiality of this healthcare experience (AU)

Logistic analysis of delayed reporting of emergency blood potassium and comparison of improved outcomes.

Potassium testing is an essential test in emergency medicine. Turnaround time (TAT) is the time between specimen receipt by the laboratory and the release of the test report. A brief in-laboratory TAT increases emergency department effectiveness. Optimizing processes to shorten TAT using other tools requires extensive time, resources, training, and support. Therefore, we aimed to find a convenient way to shorten TAT, identify risk factors affecting the timeliness of emergency potassium test reporting, and verify the intervention's effects. The dependent variable was emergency potassium reporting time > 30 or < 30 min. Logistic analysis was performed on monitorable factors, such as sex, age, potassium results, number of items, specimen processing time (including centrifugation and time before specimen loading), critical value ratio, instrument status, shift where the report was issued, specimen status, and work experience, as independent variables. In the multivariate analysis, work experience, instrument failure rate, and specimen processing time were risk factors for emergency blood potassium reporting exceeding 30 min. Improvement measures were implemented, significantly decreasing the timeout rate for acute potassium reporting. Our study confirms the usefulness of logistics in reducing the time required to report potassium levels in the emergency department, providing a new perspective on quality management.
