RESUMEN

Background: Older adults discharged from the emergency department (ED) face elevated risk of falls and functional decline. Smartphones might enable remote monitoring of mobility after ED discharge, yet their application in this context remains underexplored. Objective: This study aimed to assess the feasibility of having older adults provide weekly accelerometer data from an instrumented Timed Up-and-Go (TUG) test over an 11-week period after ED discharge. Methods: This single-center, prospective, observational, cohort study recruited patients aged 60 years and older from an academic ED. Participants downloaded the GaitMate app to their iPhones that recorded accelerometer data during 11 weekly at-home TUG tests. We measured adherence to TUG test completion, quality of transmitted accelerometer data, and participants' perceptions of the app's usability and safety. Results: Of the 617 approached patients, 149 (24.1%) consented to participate, and of these 149 participants, 9 (6%) dropped out. Overall, participants completed 55.6% (912/1639) of TUG tests. Data quality was optimal in 31.1% (508/1639) of TUG tests. At 3-month follow-up, 83.2% (99/119) of respondents found the app easy to use, and 95% (114/120) felt safe performing the tasks at home. Barriers to adherence included the need for assistance, technical issues with the app, and forgetfulness. Conclusions: The study demonstrates moderate adherence yet high usability and safety for the use of smartphone TUG tests to monitor mobility among older adults after ED discharge. Incomplete TUG test data were common, reflecting challenges in the collection of high-quality longitudinal mobility data in older adults. Identified barriers highlight the need for improvements in user engagement and technology design.

RESUMEN

BACKGROUND: Individuals with chronic obstructive pulmonary disease (COPD) constitute a significant portion of patients who present to the emergency department with dyspnea. However, there is no ideal method for predicting mortality or making hospitalization decisions in the emergency department (ED). In this regard, objective findings are needed for these patients. Since there are no objective findings regarding the hospitalization decision, there may be an increase in the re-admission rate of patients who needed hospitalization but were decided to be discharged. Side-stream end-tidal carbon dioxide (EtCO2) measurements offer a non-invasive, easy-to-interpret, quickly accessible, and reproducible method that can be applied at the bedside. OBJECTIVES: The aim of this study was to evaluate the relationship between the alpha angle values obtained by capnography and readmission rates within 30 days for patients experiencing COPD exacerbations who presented to the ED with dyspnea and were discharged after treatment. METHODS: In this study, we studied with 130 participants presented to the emergency department of a tertiary care university hospital with dyspnea, who are >18 y. Forty patients were excluded after evaluation for eligibility for the study. Thus, the data of 90 patients included were analyzed. We obtained alpha angle and EtCO2 values for all patients at the time of admission and also after treatment. The primary outcome measure of the study was the relationship between the patients' readmission situations within 30 days of the alpha angle measurements. The secondary outcome measure was the association between patients' EtCO2 values ​​and readmission within 30 days. RESULTS: It was observed that both the pretreatment alpha angle values and the posttreatment alpha angle variables were statistically significant in predicting the readmission of the patients within 30 days (p = 0.001, p = 0.003) CONCLUSION: The results of this study show that alpha angle values measured for patients with COPD who present to the ED with the complaint of dyspnea may be used to predict readmission.

RESUMEN

Objective: The present study aimed to determine the prevalence and severity of moral distress (MD) and its associated factors among emergency department nurses. Methods: This cross-sectional study was conducted in 2023 on 172 nurses from the emergency departments of medical training centers affiliated with Mazandaran University of Medical Sciences. The census method was used to collect the data, which included demographic variables and Corley's MD questionnaire. The Data were analyzed using SPSS software (version 22), using an independent T-test, analysis of variance (ANOVA), and multiple regressions. Results: Out of 172 nurses, 60.5% were women, with an average age of 32.52±6.88 years. The results demonstrated an average MD score of 69.73±25.68. In terms of frequency and intensity, around 53.5% of the participants experienced MD at a low level (0-72), while the remaining 46.5% reported experiencing it at a medium level (14-73). A significant association was found between MD and age (p=0.037), workplace hospital (p=0.005), and history of mental disorders (p=0.005). Furthermore, linear regression analysis revealed a statistically significant association between MD, marital status, and occupational type (p<0.05). Conclusion: The results showed that nurses had low to moderate levels of MD. Several factors, including age, history of mental disorders, marital status, employment type, workplace hospital, and education, were associated with the overall MD score. To reduce MD and its negative effects on nurses, it is necessary to address these factors and develop an effective strategy for identifying and managing MD to improve nursing care quality.

RESUMEN

INTRODUCTION: Emergency department (ED)-based peer recovery coach (PRC) programs can improve access to substance use disorder treatment (SUD) for ED patients. As literature on early stages of PRC implementation is limited, we conducted a qualitative assessment of ED PRC program implementation from several US-based PRC programs focusing on barriers and facilitators for implementation and providing recommendations based on the findings. METHODS: We collected qualitative data from 39 key informants (peer recovery coaches, PRC program managers, ED physicians and staff, representatives of community-based organizations) via 6 focus groups and 21 interviews in February-December 2023. We transcribed audio-recordings and analyzed data using codebook thematic analysis. RESULTS: We identified the following major themes related to specific barriers and recommendations to address them. To facilitate timely linkage to PRCs, programs would regularly inform ED staff about the program and its linkage procedures, establish trust between PRC and ED staff, streamline the linkage procedures, and choose an "opt-out" linkage approach. To address barriers related to external referrals, programs use "warm handoff" and "warm line" strategies, maintain and update a comprehensive catalog of resources, and familiarize peer coaches with local service providers. Telehealth services implementation requires addressing logistical barriers, ensuring patients' privacy, and training peer coaches on building trust and rapport online. Peer coaches' wellness and quality of services can be improved by limiting PRC's workload, prioritizing quality over quantity, facilitating self-, peer- and professional care to mitigate stress and burnout; and, importantly, by providing supportive supervision and training to peer coaches and advocating for PRC team as an equal partner in the ED settings. To facilitate PRC program adoption and sustainment program managers engage local communities and program champions, seek diverse sources of funding, and advocate for structural changes to accommodate recruitment and retention of peer recovery coaches. CONCLUSIONS: We compiled a wealth of best practices used by PRC programs to address numerous implementation barriers and challenges. These recommendations are intended for PRC program planners, managers and champions, hospital leadership, and state and local public health agencies leading SUD epidemic response.

RESUMEN

BACKGROUND: The nurse's ability to accurately identify urgent conditions and triage this vulnerable population tends to be complex and challenging. Little is known about the reliability and validity of common triage tools in geriatric patients. AIM: To determine the reliability and validity of triage tools in geriatric emergency care and summarize the specific content of current triage tools for geriatric patients. METHODS: The eligible literature was searched from the MEDLINE, CINAHL, EMBASE, and Cochrane Database using targeted search strategies. We defined the objectives and questions, set standards for article inclusion criteria, and conducted literature searching and screening. The mixed methods assessment tool (MMAT) appraised the article's quality. Finally, we extracted and analyzed the data from the included articles, summarizing the results. Endnote X9 was used for data extraction and collation. RESULTS: Nine articles were eligible. These included six triage tools: CTAS, JTAS, KTAS, MTS, SETS, and ESI. The reliability of the CTAS was good when applied to triage geriatric patients. The SETS performed well in prehospital simulated triage. The ESI has moderate to excellent reliability. The CTAS has good to excellent validity, while the JTAS, KTAS, MTS, and ESI have fair to good results. CONCLUSION: Several triage tools are useful in geriatrics, but the reliability and validity of these tools have mixed results. Applying triage tools to triage geriatric patients still has limitations.

RESUMEN

BACKGROUND: Calls to emergency departments (EDs) from ambulances to alert them to a critical case being transported to that facility that requires a special response ('pre-alerts') have been shown to improve outcomes for patients requiring immediate time-critical treatment (eg, stroke). However, little is known about their usefulness for other patients and the processes involved in ED responses to them. This study aimed to understand how pre-alerts influence patient care in the ED. METHODS: We undertook non-participant observation (162 hours, 143 pre-alerts) and semi-structured interviews with staff (n=40) in six UK EDs between August 2022 and April 2023 focusing on how ED staff respond to pre-alert calls and what influences their response. Observation notes and interview transcripts were imported into NVivo and analysed using a thematic approach. RESULTS: Pre-alert calls involved significant time and resources for ED staff but they were valued as they enabled staff to prepare for a patient's arrival (practically and psychologically). High demand and handover delays at ED created additional pre-alerts due to ambulance clinician concerns about the impact of long waits on patients.Despite the risk of pre-alert fatigue from calls for patients considered not to require a special response, ED clinicians appreciated timely pre-alert information, perceiving a higher risk from underalerting than overalerting. Variation in ED response was influenced by individual and organisational factors, particularly the resources available at the time of pre-alert. Unclear ED processes for receiving, documenting and sharing information about pre-alerts increased the risk of information loss. CONCLUSION: Improving processes for receiving and sharing pre-alert information may help ED clinicians prepare appropriately for incoming patients. Alternative routes for ambulance clinicians to seek advice on borderline pre-alert patients may help to improve the appropriateness of pre-alerts.

RESUMEN

BACKGROUND: Although one objective of NHS 111 is to ease the strain on urgent and emergency care services, studies suggest the telephone triage service may be contributing to increased demand. Moreover, while parents and caregivers generally find NHS 111 satisfactory, concerns exist about its integration with the healthcare system and the appropriateness of advice. This study aimed to analyse the advice provided in NHS 111 calls, the duration between the call and ED attendance, and the outcomes of such attendances made by children and young people (C&YP). METHODS: A retrospective cohort study was carried out of C&YP (≤17) attending an ED in the Yorkshire and Humber region of the UK following contact with NHS 111 between 1 April 2016 and 31 March 2017. This linked-data study examined NHS 111 calls and ED outcomes. Lognormal mixture distributions were fit to compare the time taken to attend ED following calls. Logistic mixed effects regression models were used to identify predictors of low-acuity NHS 111-related ED attendances. RESULTS: Our study of 348 401 NHS 111 calls found they were primarily concerning children aged 0-4 years. Overall, 13.1% of calls were followed by an ED attendance, with a median arrival time of 51 minutes. Of the 34 664 calls advising ED attendance 41% complied, arriving with a median of 38 minutes-27% of which defined as low-acuity. Although most calls advising primary care were not followed by an ED attendance (93%), those seen in an ED generally attended later (median 102 minutes) with 23% defined as low-acuity. Younger age (<1) was a statistically significant predictor of low-acuity ED attendance following all call dispositions apart from home care. CONCLUSION: More tailored options for unscheduled healthcare may be needed for younger children. Both early low-acuity attendance and late high-acuity attendance following contact with NHS 111 could act as useful entry points for clinical audits of the telephone triage service.

RESUMEN

INTRODUCTION: The decisions of withholding or withdrawing life-sustaining treatments are difficult to make in the context of emergency departments (EDs) because most patients are unable to communicate. Relatives are thus asked to participate in the decision-making process, although they are unprepared to face such situations. We therefore aimed to develop a standardised intervention for announcing decisions of withholding or withdrawing life-sustaining treatments in EDs and assess the efficacy of the intervention on the stress of relatives. METHODS AND ANALYSIS: The DISCUSS trial is a multicentre stepped-wedge cluster randomised study and will be conducted at nine EDs in France. A standardised intervention based on human simulation will be codesigned with partner families and implemented at three levels: the relatives, the healthcare professionals (HCP) and the EDs. The intervention will be compared with a control based on treatment as usual. A total of 538 families are planned to be included: 269 in the intervention group and 269 in the control group. The primary endpoint will be the symptoms of post-traumatic stress disorder (PTSD) at 90 days. The secondary endpoints will be symptoms of PTSD at 7 and 30 days, diagnosis of PTSD at 90 days and anxiety and depression scores at 7, 30 and 90 days. Satisfaction regarding the training, the assertiveness in communication and real-life stress of HCPs will be measured at 90 days. ETHICS AND DISSEMINATION: This study was approved by the ethics committee Est III from Nancy and the French national data protection authority. All relatives and HCPs will be informed regarding the study objectives and data confidentiality. Written informed consent will be obtained from participants, as required by French law for this study type. The results from this study will be disseminated at conferences and in a peer-reviewed journal. TRIAL REGISTRATION NUMBER: NCT06071078.

RESUMEN

Introduction: Workplace violence against healthcareworkers in Emergency Departments (EDs) is a global concern. The purpose of this study was to determine the prevalence and types of workplace violence in EDs. Methods: a cross-sectional survey was conducted in three public sector hospital EDs in Gauteng, South Africa. A self-administered, standardised online questionnaire developed by the World Health organization was used to collect data between March and November 2022. A total of 65 healthcareworkers which consisted of nurses (24) and doctors (41) participated in the study. Results: The prevalence of workplace violence was 73.8 % with verbal abuse being the most common type at 66 %. Eighty-two percent of the victims did not report the incident. Poor communication and lack of mutual respect among staff and healthcare users contributed to both physical and non-physical workplace violence. Conclusion: Workplace violence appears to be a common occurrence in EDs in the hospitals surveyed in Gauteng. It is regarded as a typical incident by respondents, and it is underreported. It has a direct negative impact on healthcareworkers and their working environment and indirectly on patients. Urgent attention from all stakeholders is needed to minimize the prevalence of these incidents.

RESUMEN

INTRODUCTION: Previous studies have shown that substantial percentages of emergency department (ED) patients in the USA recommended for HIV or hepatitis C (HCV) decline testing. Evidence-based and cost-effective interventions to improve HIV/HCV testing uptake are needed, particularly for people who inject drugs (PWIDs) (currently or formerly), who comprise a group at higher risk for these infections. We developed a brief persuasive health communication intervention (PHCI) designed to convince ED patients who had declined HIV/HCV testing to agree to be tested. In this investigation, we will determine if the PHCI is more efficacious in convincing ED patients to be tested for HIV/HCV when delivered by a video or in person, and whether efficacy is similar among individuals who currently, previously or never injected drugs. METHODS AND ANALYSIS: We will conduct a multisite, randomised controlled trial comparing PHCIs delivered by video versus in person by a health educator to determine which delivery method convinces more ED patients who had declined HIV/HCV testing instead to be tested. We will stratify randomisation by PWID status (current, former or never/non-PWID) to permit analyses comparing the PHCI delivery method by injection-drug use history. We will also perform a cost-effectiveness analysis of the interventions compared with current practice, examining the incremental cost-effectiveness ratio between the two interventions for the ED population overall and within individual strata of PWID. As an exploratory analysis, we will assess if a PHCI video with captions confers increased or decreased acceptance of HIV/HCV testing, as compared with a PHCI video without captions. ETHICS AND DISSEMINATION: The study protocol has been approved by the institutional review board of the Icahn School of Medicine. The results will be disseminated at international conferences and in peer-reviewed publications. TRIAL REGISTRATION NUMBER: NCT05968573.

RESUMEN

BACKGROUND: The COVID-19 pandemic has had a major impact on the access and delivery of healthcare services, posing unprecedented challenges to healthcare staff worldwide. Frontline healthcare staff faced unique stressors and challenges that impact their well-being and patient care. This qualitative study aimed to explore the experiences and perspectives of frontline ED healthcare staff on emergency care services during the COVID-19 pandemic, providing valuable insights into the challenges, adaptations, and lessons learned in delivering emergency care. METHODS: This study utilized a qualitative approach. In-depth semi-structured interviews were conducted with 30 ED healthcare staff from three different hospitals located in Turkey between 15/03/2022 and 30/04/2022. Convenience sampling was used to recruit participants. The duration of the interviews ranged from 28 to 37 min. Data saturation was reached as no new information was gathered. The data were analyzed using the thematic analysis method. NVivo software was used to manage the data analysis process. Member check was carried out to ensure that the generated themes conformed to the participants' views. RESULTS: 15 sub-themes under three themes emerged: (1) the impact of COVID-19 on emergency care services, including sub-themes of "introducing a COVID-19 unit in the ED", "changes in the routine functioning of EDs", "changes in the number of ED visits", "quality of care", "resources", and "increased workload"; (2) the psychological effects of COVID-19 on ED healthcare staff, including sub-themes of "staying away from family", "fear", "society's perspective on healthcare professionals", "morale-staff burnout", "psychological and emotional effects", and "unable to receive sufficient support"; and (3) the difficulties faced by ED healthcare staff, including sub-themes of "difficult working conditions", "community-based effects difficulties", and "COVID-19 is an unknown situation". CONCLUSION: Staff burnout threatens the quality of patient care and staff retention, and therefore this should be addressed by ED directors and leaders. This study could inform appropriate stakeholders regarding lessons learned from COVID-19 to better manage future pandemics. Learning from such lived experiences and developing appropriate interventions to minimize the difficulties faced during COVID-19 would allow better management of future pandemics. This study calls for a reform to address the challenges faced by healthcare staff, improve the overall response to public health crises, and enhance the resilience of healthcare systems for future crises.

RESUMEN

BACKGROUND: Hyperlactatemia has been recognized as a significant prognostic indicator in critically ill patients. Nonetheless, there remains a gap in understanding the specific risk factors contributing to increased mortality among undifferentiated emergency department (ED) patients presenting with elevated lactate levels. OBJECTIVES: The objective of the study is to investigate potential risk factors for 30-day in-hospital mortality in ED patients with hyperlactatemia. METHODS: All nontraumatic adult presentations to the ED who had a lactate level of ≥2.5 mmol/L were included. Comorbidities, vital signs, lactate levels, lactate clearance, lactate normalization, and final diagnosis were compared with 30-day in-hospital mortality. RESULTS: A 30-day in-hospital mortality rate of 10.4% was observed in 979 patients. The mortality rate was higher in hypotensive patients (odds ratio [OR] 4.973), in nursing home patients (OR 5.689), and bedridden patients (OR 3.879). The area under the curve for the second lactate level (0.804) was higher than the first lactate level (0.691), and lactate clearance (0.747) for in-hospital mortality. A second lactate level >3.15 mmol/l had a sensitivity of 81.3% in predicting in-hospital mortality. The OR for mortality was 6.679 in patients without lactate normalization. A higher mortality rate was observed in patients with acute renal failure (OR 4.305), septic shock (OR 4.110), and acute coronary syndrome (OR 2.303). CONCLUSIONS: A second lactate measurement more accurately predicts in-hospital mortality than lactate clearance and the first lactate level in ED patients. Nursing home patients, bed-ridden patients, hypotensive patients on initial ED presentation, patients without lactate normalization, and patients with a final diagnosis of acute renal failure, septic shock, and acute coronary syndrome had a higher mortality rate.

RESUMEN

Because emergency departments are often the first point of contact for victims of violence, it is critical to provide the appropriate treatment in compliance with all necessary medicolegal precautions. For this reason, a randomized controlled trial was conducted at the Policlinico Hospital of Milan (Italy) in which an intervention group (12 physicians) received a 6-h course on clinical forensic medicine and their performance in medicolegal procedures in claimed cases of violence was compared with that of a control group (13 physicians) by means of a 16-item assessment scale over the 3 months before and the 3 months after the course. Overall, 195 medical records were included in the statistical analysis. Out of these cases, 105 occurred before the course (60 analyzed by the control group and 45 by the intervention group) and 90 occurred after the course (45 analyzed by the control group and 45 by the intervention group). The results showed that the overall mean score of physicians who participated to the course increased from 14.0 (IQR 7.0) to 19.0 (IQR 8.0) with a p-value < 0.0001 and that the comparison between the intervention group and the control group after the course was 19.0 (IQR = 8.0) and 14.0 (IQR = 7.0), respectively, with a p-value < 0.0001. The improvement was very little and below the expectations pointing out that educational courses, although they can be a first step towards raising the ED physicians' awareness of clinical forensics, may not be enough and that more structured training and new strategies should be implemented.

RESUMEN

Background: The COVID-19 pandemic significantly impacted emergency department (ED) operations and patient care. Understanding its effects on nursing processes, triage accuracy, and wait times is pivotal for optimizing outcomes. Objectives: This study aimed to analyze the differences in nursing processes, triage accuracy, and wait times before and during the COVID-19 pandemic. Design: A retrospective cohort study. Methods: The study analyzed 224 electronic medical records from a single ED, with 120 records from the pre-pandemic period (January 2019-February 2020) and 104 records from the pandemic period (March 2020-March 2021). Dependent variables included missed nursing care per validated scales, triage accuracy per Emergency Severity Index, and wait times for nursing triage and physician examination. Independent factors encompassed sociodemographic, clinical characteristics, and organization dynamics. Results: Sociodemographic and clinical profiles were comparable between periods. Triage accuracy remained high except for older patients. Nursing triage wait times differed little, yet physician examination and urgent case waits decreased amidst the pandemic. Nursing documentation completeness, such as recording patient status and mental state, augmented during this crisis period. Conclusion: This evaluation identified differences in triage accuracy, wait times, and documentation completeness before and during the COVID-19 pandemic period at a single institution. Patient age and clinical status influenced some metrics. Lessons from comparing precrisis benchmarks to intra-pandemic nursing performance may guide pandemic preparedness strategies. Further research is warranted to optimize emergency processes and outcomes during public health emergencies, as well as examine strategies through multicenter investigations comparing prepandemic to intra-pandemic performance to provide broader insights into challenges and inform efforts to bolster emergency care through future crises.

RESUMEN

Zinc deficiency is a significant global health concern among children, manifesting in various acquired and inherited conditions. This comprehensive overview of acquired and inherited zinc deficiency-related diseases in children aimed to explore the clinical presentations, diagnostic challenges, and management strategies associated with these conditions. This case series elucidates the diverse clinical manifestations of zinc deficiency in pediatric patients, ranging from dermatitis and growth retardation to immune dysregulation and neurological abnormalities, and discusses the underlying genetic mechanisms, clinical phenotypes, and therapeutic interventions. The complexity of zinc deficiency-related diseases in children underscores the need for a multidisciplinary approach involving pediatricians, dermatologists, geneticists, and nutritionists to optimize patient care and outcomes.

RESUMEN

PURPOSE: To study the proportion and predictors of outpatient physician follow-up within 60 days of substance-related emergency department (ED) visits for Ontario youth. METHODS: We examined administrative data on substance-related ED visits before and during the COVID-19 pandemic among youths aged 10-24 years in Ontario, Canada. Substance-related visits were identified using International Classification of Diseases-10-CA codes. We described demographic characteristics, receipt of mental health services in the year before the ED visit, disposition from the ED, and follow-up services within 60 days of the ED visit. RESULTS: Between April 1, 2017, and May 31, 2021, 64,236 youth had at least one ED visit for substance use. Visits for alcohol were the most common (49%), followed by cannabis (32.3%). ED visits for all substances were more prevalent during the pandemic than prepandemic, except visits for alcohol. The receipt of follow-up physician care for substance use was low (33.2% prepandemic) but increased during the pandemic (41.7%; adjusted odds ratio 1.34, 95% CI 1.28, 1.39) and varied between substances. Mental health service history in the year before the substance-related ED visit had the strongest association with receipt of follow-up physician care within 60 days (adjusted odds ratio 6.86, 95% CI 6.57, 7.17). DISCUSSION: Youth frequently do not receive physician follow-ups within two months of the substance-related ED visit, although higher follow-up proportions were seen during the pandemic after the implementation of virtual care. Further research is required to understand why follow-up is low and to examine interventions that can increase connection to care.

RESUMEN

AIMS: To evaluate the impact of spatial separation on patient flow in the emergency department. DESIGN: This was a retrospective, time-and-motion analysis conducted from 15 to 22 August, 2022 at the emergency department of a tertiary hospital in Kuala Lumpur, Malaysia. During this duration, spatial separation was implemented in critical and semi-critical zones to separate patients with symptoms of respiratory infections into respiratory area, and patients without into non-respiratory area. This study adhered to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines. METHODS: Patients triaged to critical and semi-critical zones were included in this study. Timestamps of patient processes in emergency department until patient departure were documented. RESULTS: The emergency department length-of-stay was longer in respiratory area compared to non-respiratory area; 527 min (381-698) versus 390 min (285-595) in critical zone and 477 min (312-739) versus 393 min (264-595) in semi-critical zone. In critical zone, time intervals of critical flow processes and compliance to hospital benchmarks were similar in both areas. More patients in respiratory area were managed within the arrival-to-contact ≤30 min benchmark and more patients in non-respiratory area had emergency department length-of-stay ≤8 h. CONCLUSIONS: The implementation of spatial separation in infection control should address decision-to-departure delays to minimise emergency department length of stay. IMPACT: The study evaluated the impact of spatial separation on patient flow in the emergency department. Emergency department length-of-stay was significantly prolonged in the respiratory area. Hospital administrators and policymakers can optimise infection control protocols measures in emergency departments, balancing infection control measures with efficient patient care delivery. REPORTING METHOD: STROBE guidelines. NO PATIENT OR PUBLIC CONTRIBUTION: None. TRIAL AND PROTOCOL REGISTRATION: The study obtained ethics approval from the institution's Medical Ethics Committee (MREC ID NO: 20221113-11727). STATISTICAL ANALYSIS: The author has checked and make sure our submission has conformed to the Journal's statistical guideline. There is a statistician on the author team (Noor Azhar).

RESUMEN

BACKGROUND: The COVID-19 pandemic social distancing requirements encouraged patients to avoid public spaces including in-office health care visits. Ambulatory-care-sensitive conditions (ACSCs) represent conditions that can be managed with quality primary care and when access is limited, these conditions can lead to avoidable emergency department (ED) visits. METHODS: Using national data on ED visits from 2019 to 2021 in the National Hospital Ambulatory Care Survey, we examined the impact of COVID-19 pandemic on ACSC ED visits among older adults (aged ≥65). RESULTS: The proportion of ED visits among older adults that were for ACSCs increased between 2019 (17.4%) and 2021 (18.5%). The trend in both rural (26.4%-28.6%) and urban areas (15.4%-16.8%) shows a significant jump from 2019 to 2021 (P < .001). CONCLUSIONS: This rise in ACSC ED use is consistent with a delay in normal primary care during the pandemic.

RESUMEN

INTRODUCTION: Timely arrival of emergency medical services (EMS) is pivotal for effective prehospital care, and efforts by EMS leaders and policymakers to reduce response times, especially in cardiac arrests responsible for 70%-80% of coronary heart disease-related deaths, underscore the global urgency. With approximately 55 out-of-hospital cardiac arrests per 100 000 people annually, survival rates hinge on timely cardiopulmonary resuscitation, emphasising its initiation within a 4-6 min window. Trauma, causing 6 million deaths and nearly 40 million injuries a year, further underscores the need for prompt prehospital care. Acknowledging these challenges, health systems have incorporated community first responder (CFR) models, where trained community members provide initial aid, aiming to bridge the crucial gap until professional help arrives. This scoping review intends to explore the experiences of various countries with CFR models, including their conceptual and theoretical frameworks, recognising CFR as a critical solution for reducing response times in prehospital emergency care. METHODS AND ANALYSIS: Arksey and O'Malley's approach will be followed in this scoping review. Our protocol was drafted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols extension for Scoping Reviews. The study objective is to comprehensively understand and map current knowledge about CFR model characteristics and identify effective components and indicators. The review will encompass available articles indexed in PubMed, Scopus and Web of Science without restrictions on date of publication. Additional searches will explore grey literature on Google Scholar and reliable websites in the field of EMS. Articles published in languages other than English and those inaccessible in full text will not be considered for inclusion. ETHICS AND DISSEMINATION: Since the study data are accessible from publicly accessible secondary sources, no ethical approval is necessary. Peer-reviewed publications will be used to report the study findings.

RESUMEN

INTRODUCTION: Measuring elevated post-void residual volume is important for diagnosing urinary outflow tract obstruction and cauda equina syndrome. Catheter placement is exact but painful, invasive, and may cause infection, whereas an ultrasound is accurate, painless, and safe. AIM: The purpose of this single-center study is to evaluate the accuracy of a module for artificial-intelligence (AI)-based fully automated bladder volume (BV) prospective measurement using two-dimensional ultrasound images, as compared with manual measurement by expert sonographers. METHODS: Pairs of transverse and longitudinal bladder images were obtained from patients evaluated in an urgent care clinic. The scans were prospectively analyzed by the automated module using the prolate ellipsoid method. The same examinations were manually measured by a blinded expert sonographer. The two methods were compared using the Pearson correlation, kappa coefficients, and the Bland-Altman method. RESULTS: A total of 111 pairs of transverse and longitudinal views were included. A very strong correlation was found between the manual BV measurements and the AI-based module with r = 0.97 [95% CI: 0.96-0.98]. The specificity and sensitivity for the diagnosis of an elevated post-void residual volume using a threshold ≥200 mL were 1.00 and 0.82, respectively. An almost-perfect agreement between manual and automated methods was obtained (kappa = 0.85). Perfect reproducibility was found for both inter- and intra-observer agreements. CONCLUSION: This AI-based module provides an accurate automated measurement of the BV based on ultrasound images. This novel method demonstrates a very strong correlation with the gold standard, making it a potentially valuable decision-support tool for non-experts in acute settings.
