Background. In 2008, the National Highway Traffic Safety Administration funded the development of a model process for the development and implementation of evidence-based guidelines (EBGs) for emergency medical services (EMS). We report on the implementation and evaluation of an evidence-based prehospital pain management protocol developed using this model process. Methods. An evidence-based protocol for prehospital management of pain resulting from injuries and burns was reviewed by the Protocol Review Committee (PRC) of the Maryland Institute for Emergency Medical Services Systems (MIEMSS). The PRC recommended revisions to the Maryland protocol that reflected recommendations in the EBG: weight-based dosing and repeat dosing of morphine. A training curriculum was developed and implemented using Maryland's online Learning Management System and successfully accessed by 3,941 paramedics and 15,969 BLS providers. Field providers submitted electronic patient care reports to the MIEMSS statewide prehospital database. Inclusion criteria were injured or burned patients transported by Maryland ambulances to Maryland hospitals whose electronic patient care records included data for level of EMS provider training during a 12-month preimplementation period and a 12-month postimplementation period from September 2010 through March 2012. We compared the percentage of patients receiving pain scale assessments and morphine, as well as the dose of morphine administered and the use of naloxone as a rescue medication for opiate use, before and after the protocol change. Results. No differences were seen in the percentage of patients who had a pain score documented or the percent of patients receiving morphine before and after the protocol change, but there was a significant increase in the total dose and dose in mg/kg administered per patient. During the postintervention phase, patients received an 18% higher total morphine dose and a 14.9% greater mg/kg dose. Conclusions. We demonstrated that the implementation of a revised statewide prehospital pain management protocol based on an EBG developed using the National Prehospital Evidence-based Guideline Model Process was associated with an increase in dosing of narcotic pain medication consistent with that recommended by the EBG. No differences were seen in the percentage of patients receiving opiate analgesia or in the documentation of pain scores. [ABSTRACT FROM AUTHOR]

Abstract: The communities of sub-Saharan Africa face a disproportionate burden of acute injury and illness. While acute care systems can substantially lower the morbidity and mortality associated with a wide range of medical and surgical conditions in adults and children, few healthcare facilities in the region adopt an integrated approach to resuscitation and stabilization. The term acute care encompasses the health system components used to treat patients with urgent or emergent conditions, and governments, health care facilities, funders, and academic institutions would benefit from a clearer understanding of acute care in an African context. In November 2011, the African Federation of Emergency Medicine held the first in a series of conferences on acute care in Africa to engage stakeholders in the development of consensus statements for the region. This first meeting engaged a range of acute and emergency care providers working in sub-Saharan Africa, and effective acute care was defined as: The provision of initial resuscitation, stabilization, and treatment to acutely ill and injured patients, and delivery of those patients to the best available definitive care, regardless of their ability to pay. Focus areas included: (1) Acute care referral systems (pre-facility, transfer, and field care), (2) Facility-based acute care, (3) Emergency medicine specialist training, (4) Emergency nursing, (5) Sustainability strategies (advocacy, policy, and funding). The resulting consensus document is presented here and will be expanded and specified in future sessions of the conference series. [Copyright &y& Elsevier]

BACKGROUND: Recent studies indicate that the composition of fine particulate matter [PM≤2.5 μm in aerodynamic diameter (PM2.5)] is associated with increased hospitalizations for cardiovascular and respiratory diseases. The metal composition of PM2.5 influences allergic and/or inflammatory reactions, and ambient zinc contributes to worsening pulmonary function in susceptible adults. However, information is limited concerning associations between ambient air zinc levels and health care utilization for asthma, especially among children. OBJECTIVE: We aimed to investigate the relationship between outdoor ambient air PM2.5 zinc levels and urgent health care utilization for children living in an urban area. METHODS: We used a time-series study to estimate the association of ambient air PM2.5 zinc levels with hospital admissions and emergency department (ED) utilization by children in Baltimore, Maryland, controlling for time trends. We used data from daily discharge administrative claims of ED and hospital utilization for asthma in children, 0-17 years of age for Greater Baltimore from June 2002 through November 2002. We collected ambient air PM2.5 metal concentration data, determined by X-ray fluorescence spectroscopy, during the U.S. Environmental Protection Agency-sponsored Baltimore Supersite project. RESULTS: Previous-day medium levels of zinc (8.63-20.76 ng/m³) are associated with risks of pediatric asthma exacerbations that are 1.23 (95% confidence interval, 1.07-1.41) times higher than those with previous-day low levels of zinc (< 8.63 ng/m³) after accounting for time-varying potential confounders. CONCLUSION: Results suggest that high ambient air PM2.5 zinc levels are associated with an increase in ED visits/hospital admissions for asthma on the following day among children living in an urban area.

Emergency department (ED) screening for intimate partner violence (IPV) faces logistic difficulties and has uncertain efficacy. We surveyed 146 ED visitors and 1 08 ED care providers to compare their support for ED IPV screening in three hypothetical scenarios of varying IPV risk. Visitor support for screening was 5 times higher for the high-risk (86%) than for the low-risk (17%) scenario. Providers showed significantly more support for the need for ED IPV screening than visitors. Controlling for confounding by gender, race, experience with IPV, hospital, and marital status did not affect comparisons between groups. These responses indicate greater support for IPV screening in the ED for high-risk than for low-risk cases, particularly among visitors. [ABSTRACT FROM AUTHOR]

Intimate partner violence (IPV) constitutes a major public health problem in the United States. This cross-sectional survey of 108 emergency department (ED) care providers and 146 ED visitors at three metropolitan EDs compared the beliefs of ED health care providers with those of community members about the relative benefits of the helpfulness of resources for IPV victims using hypothetical case scenarios. Although providers generally indicated that help resources were helpful in all scenarios, visitors were more discriminating, showing less support for resources in the lower-risk scenario. Regarding differences between groups, visitors selected police and attorneys more frequently than providers as a helpful resource, whereas providers selected shelters and counselors more frequently than visitors. Adjustment for previous experience with IPV did not change these results. Understanding the differences between health care providers' and community members' perceptions of resources for victims of IPV may improve the effectiveness of referral to IPV resources.

The event of high emergency department (ED) utilization or inaccessibility to the ED may result in hospital after hospital in a city not accepting new patients in need of urgent medical care. We call this a cascading event. In this paper, we investigate cascading events among 11 EDs in Baltimore City in 2018 and 2019 using a two-state Markov model. Additionally, the transition probabilities are used to monitor the evolution of cascading events. Meanwhile, we predict the expected remaining hours in each state. After we calculate and compare the probabilities of having a cascading event for each ED, we finally identify the similarity and heterogeneity among EDs using cluster analysis. The findings of our study reveal that the continuous yellow alerts at Johns Hopkins Hospital, Johns Hopkins Bayview Medical Center (JH Bayview), Sinai Hospital, and the University of Maryland Medical Center (UMMC) are associated with a large chance of having a cascading event in the city that affects all 11 hospitals. Weekdays dramatically increased chances of having a cascading event. [ABSTRACT FROM AUTHOR]

The author reflects on the move of the World Health Organization (WHO) to raise the pandemic alert level of H1N1 influenza A virus to Phase 6 worldwide. The author believes that the agency should not have raise the pandemic level because only time will tell how it will evolve and resolve. Moreover, he adds that people should strive to immediately identify and treat hospitalized H1N1 patients with antivirals, to communicate new information and to prepare for future waves of the disease.

Study Objective: Helicopter emergency medical services (EMS) has become a well-established component of modern trauma systems. It is an expensive, limited resource with potential safety concerns. Helicopter EMS activation criteria intended to increase efficiency and reduce inappropriate use remain elusive and difficult to measure. This study evaluates the effect of statewide field trauma triage changes on helicopter EMS use and patient outcomes.Methods: Data were extracted from the helicopter EMS computer-aided dispatch database for in-state scene flights and from the state Trauma Registry for all trauma patients directly admitted from the scene or transferred to trauma centers from July 1, 2000, to June 30, 2011. Computer-aided dispatch flights were analyzed for periods corresponding to field triage protocol modifications intended to improve system efficiency. Outcomes were separately analyzed for trauma registry patients by mode of transport.Results: The helicopter EMS computer-aided dispatch data set included 44,073 transports. There was a statewide decrease in helicopter EMS usage for trauma patients of 55.9%, differentially affecting counties closer to trauma centers. The Trauma Registry data set included 182,809 patients (37,407 helicopter transports, 128,129 ambulance transports, and 17,273 transfers). There was an increase of 21% in overall annual EMS scene trauma patients transported; ground transports increased by 33%, whereas helicopter EMS transports decreased by 49%. Helicopter EMS patient acuity increased, with an attendant increase in patient mortality. However, when standardized with W statistics, both helicopter EMS- and ground-transported trauma patients showed sustained improvement in mortality.Conclusion: Modifications to state protocols were associated with decreased helicopter EMS use and overall improved trauma patient outcomes.

Introduction: Low-resourced settings often lack personnel and infrastructure for alcohol use disorder treatment. We culturally adapted a Brief Negotiational Interview (BNI) for Emergency Department injury patients, the "Punguza Pombe Kwa Afya Yako (PPKAY)" ("Reduce Alcohol For Your Health") in Tanzania. This study aimed to evaluate the feasibility of a pragmatic randomized adaptive controlled trial of the PPKAY intervention. Materials and methods: This feasibility trial piloted a single-blind, parallel, adaptive, and multi-stage, block-randomized controlled trial, which will subsequently be used to determine the most effective intervention, with or without text message booster, to reduce alcohol use among injury patients. We reported our feasibility pilot study using the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework, with recruitment and retention rates being our primary and secondary outcomes. We enrolled adult patients seeking care for an acute injury at the Kilimanjaro Christian Medical Center in Tanzania if they (1) exhibited an Alcohol Use Disorder Identification Test (AUDIT) ≥8, (2) disclosed alcohol use prior to injury, or (3) had a breathalyzer ≥0.0 on arrival. Intervention arms were usual care (UC), PPKAY, PPKAY with standard text booster, or a PPKAY with a personalized text booster. Results: Overall, 181 patients were screened and 75 enrolled with 80% 6-week, 82.7% 3-month and 84% 6-month follow-up rates showing appropriate Reach and retention. Adoption measures showed an overwhelmingly positive patient acceptance with 100% of patients perceiving a positive impact on their behavior. The Implementation and trial processes were performed with high rates of PPKAY fidelity (76%) and SMS delivery (74%). Intervention nurses believed Maintenance and sustainability of this 30-minute, low-cost intervention and adaptive clinical trial were feasible. Conclusions: Our intervention and trial design are feasible and acceptable, have evidence of good fidelity, and did not show problematic deviations in protocol. Results suggest support for undertaking a full trial to evaluate the effectiveness of the PPKAY, a nurse-driven BNI in a low-income country.

Background Matricellular proteins comprising matrisome and adhesome are responsible for structure integrity and interactions between cells in the tumour microenvironment of breast cancer. Changes in the gene expression of matrisome and adhesome augment metastasis. Since inflammatory breast cancer (IBC) is characterized by high metastatic behaviour. Herein, we compared the gene expression profile of matrisome and adhesome in non-IBC and IBC in fresh tissue and ex vivo patient-derived explants (PDEs) and we also compared the secretory inflammatory mediators of PDEs in non-IBC and IBC to identify secretory cytokines participate in cross-talk between cells via interactions with matrisome and adhisome. Methods Fifty patients (31 non-IBC and 19 IBC) were enrolled in the present study. To test their validation in clinical studies, PDEs were cultured as an ex vivo model. Gene expression and cytokine array were used to identify candidate genes and cytokines contributing to metastasis in the examined fresh tissues and PDEs. Bioinformatics analysis was applied on identified differentially expressed genes using GeneMANIA and Metascape gene annotation and analysis resource to identify pathways involved in IBC metastasis. Results Normal and cancer fresh tissues and PDEs of IBC were characterized by overexpression of CDH1 and MMP14 and downregulation of CTNNA1 and TIMP1 compared with non-IBC. The secretome of IBC cancer PDEs is characterized by significantly high expression of interleukin 6 and monocyte chemoattractant protein-1 (CCL2) compared with non-IBC. Conclusion Genes expressed by adhisome and matrisome play a significant role in IBC metastasis and should be considered novel target therapy. [ABSTRACT FROM AUTHOR]

Background: Numerous trauma scoring systems have been developed in an attempt to accurately and efficiently predict the prognosis of emergent trauma cases. However, it has been questioned as to whether the accuracy and pragmatism of such systems still hold in lower-resource settings that exist in many hospitals in lower- and middle-income countries (LMICs). In this study, it was hypothesized that the physiologically-based Revised Trauma Score (RTS), Mechanism/Glasgow Coma Scale/Age/Pressure (MGAP) score, and Glasgow Coma Scale/Age/Pressure (GAP) score would be effective at predicting mortality outcomes using clinical data at presentation in a representative LMIC hospital in Upper Egypt.Methods: This was a retrospective analysis of the medical records of trauma patients at Beni-Suef University Hospital. Medical records of all trauma patients admitted to the hospital over the 8-month period from January to August 2016 were reviewed. For each case, the RTS, MGAP, and GAP scores were calculated using clinical data at presentation, and mortality prediction was correlated to the actual in-hospital outcome.Results: The Area Under the Receiver Operating Characteristic (AUROC) was calculated to be 0.879, 0.890, and 0.881 for the MGAP, GAP, and RTS respectively, with all three scores showing good discriminatory ability. With regards to prevalence-dependent statistics, all three scores demonstrated efficacy in ruling out mortality upon presentation with negative predictive values > 95%, while the MGAP score best captured the mortality subgroup with a sensitivity of 94%. Adjustment of cutoff scores showed a steep trade-off between optimizing the positive predictive values versus the sensitivities.Conclusion: The RTS, MGAP, and GAP all showed good discriminatory capabilities per AUROC. Given the relative simplicity and potentially added clinical benefit in capturing critically ill patients, the MGAP score should be further studied for stratifying risk of incoming trauma patients to the emergency department, allowing for more efficacious triage of patients in lower-resource healthcare settings.

Background: Workplace violence (WPV) has been recognized as a major occupational hazard worldwide. Healthcare professions are particularly at a higher risk of WPV. Patients and their relatives are commonly the most common perpetrators for WPV against physicians. Trainings on the universal precautions of violence, how to effectively anticipate, recognize and manage potentially violent situation is recommended by OSHA as a part of a written, effective, comprehensive, and interactive WPV prevention program. Objective: To implement and evaluate the effectiveness of a training session delivered to nurses. The training session aimed to increase nurses' ability to identify potentially violent situations and to effectively manage these situations in a teaching hospital in Egypt. Methodology: A total of 99 nurses attended the training sessions. Confidence in coping with aggressive patient scale, along with nurses' attitudes toward WPV, were used to assess the effectiveness of the training sessions. Results: Nurses' perceived confidence to deal with aggression increased after attending the training sessions. Nurses' attitudes toward WPV positively changed after attending the training session. Conclusion and recommendations: Increasing awareness of the problem among healthcare professions as well as the public is warranted. Violence prevention program with a zero-tolerance policy is warranted. [ABSTRACT FROM AUTHOR]

Background: Alcohol use in resource-limited settings results in significant morbidity and mortality. These settings lack the necessary specialty-trained personnel and infrastructure. Therefore, implementing evidence-based interventions from high-income settings, like a brief negotiational intervention (BNI) for alcohol, will require rapid production of evidence of effectiveness to guide implementation priorities. Thus, this study describes a clinical trial protocol to rapidly optimize and evaluate the impact of a culturally adapted BNI to reduce alcohol-related harms and alcohol consumption among injury patients.Methods: Our pragmatic, adaptive, randomized controlled trial (PRACT) is designed to determine the most effective intervention approach to reduce hazardous alcohol use among adult (≥18 years old) in acute (< 24 h) injury patients. Our culturally adapted, nurse-delivered, intervention (PPKAY) has been augmented with evidence-based, culturally appropriate standards and will be evaluated as follows. Stage 1 of the trial will determine if PPKAY, either with a standard short-message-service (SMS) booster or with a personalized SMS booster is more effective than usual care (UC). While optimizing statistical efficiency, Stage 2 drops the UC arm to compare the PPKAY with a standard SMS booster to PPKAY with a personalized SMS booster. Finally, in Stage 3, the more effective arm in Stage 2 is compared to PPKAY without an SMS booster. The study population is acute injury patients who present to Kilimanjaro Christian Medical Centre, Tanzania, who (1) test alcohol positive by breathalyzer upon arrival; (2) have an Alcohol Use Disorder Identification Test of 8 or above; and/or (3) have reported drinking alcohol prior to their injury. Outcome measures will be evaluated for all arms at 3, 6, 9, 12, and 24 months. The primary outcome for the study is the reduction of the number of binge drinking days in the 4 weeks prior to follow-up. Secondary outcomes include alcohol-related consequences, measured by the Drinker Inventory of Consequences.Discussion: The findings from this study will be critically important to identify alcohol harm reduction strategies where alcohol research and interventions are scarce. Our innovative and adaptive trial design can transform behavior change research and identify the most effective nurse-driven intervention to be targeted for integration into standard care.Trial Registration: ClinicalTrials.gov NCT04535011 .

Background: Voodoo is a heterogeneous mixture of psychoactive substances that has recently grown in popularity among youth in Egypt. Patients can present with a variety of manifestations that may lead to death in some cases. This study assessed the acute toxic effects of voodoo among patients presented to the Poison Control Center of Ain Shams University Hospitals (PCC-ASUH) during a one year period. Methods: This is a retrospective study of all patients presented with voodoo intoxication at the PCC-ASUH from 1 January 2017 to 31 December 2017. Clinical data, routine laboratory findings, and ECG results as well as duration of hospitalization and outcome were compiled from hospital records. Results: Seventy-one voodoo intoxication cases meeting the inclusion criteria were analyzed (mean age: 25.19 ± 9.54 years, range: 15–50 years, 97.2 % male). Pulse, blood pressure, and respiratory rate were normal in more than half of all patients. Neurological abnormalities including agitation, hallucinations, disturbance of consciousness were the most frequent manifestations. Respiratory acidosis was the most common laboratory finding (54.9 %), followed by increased serum urea (43.6 %), hypokalemia (33.8 %), hyperglycemia (28.1 %), and leukocytosis (26.7 %). The most common ECG finding was sinus tachycardia (31 %), followed by QT prolongation (15.4 %). More than half of the studied patients (53.5 %) co-administered other illicit substances, most frequently cannabis and tramadol. Most patients recovered fully and were discharged, but death occurred in two cases. Conclusions: Voodoo toxicity can manifest with many presentations, hampering timely diagnosis. Clinicians should consider possible voodoo poisoning in patients presenting with a history of drug use with neurological symptoms, and they should conduct follow-up arterial blood gases, electrolytes and ECG as voodoo may contain potentially fatal psychoactive substances.

Background: Childhood injuries are a significant and growing global public health problem, often with high morbidity and, at times, mortality. A large proportion of injuries in preschool children occur in or around the home. We aimed to identify socioeconomic and demographic factors associated with preschool children injuries in Egypt.Methods: Secondary data analysis were done for the Egyptian Demographic and Health Surveys (EDHS), 2014. Potential associated factors were measured from data on child welfare and questions on the prevalence of accidents and injuries of preschool children. These data were linked to the children demographic data, maternal age at marriage, working status of the mother, and questions on childcare arrangements.Results: Out of the 634 injured children, 520 (83.4%) children required medical care for their injuries. The most common reported injury was an open wound 288 (45.5%), followed by fractures 237 (35.7%), burns 124 (19.7%), electrical shock 12 (1.9%) and other unknown types of injury 15 (2.4%). There was a positive correlation between injury and child's age, household wealth, mother's age at marriage, and unsupervised children or children left in the care of a minor.Conclusion: Leaving children unsupervised or in the presence of other young children is significantly associated with the occurrence of child injuries.

Background: Cardiopulmonary resuscitation (CPR) is a fundamental skill that should be acquired by all medical community members. This study aims to evaluate the knowledge and attitudes of junior doctors and medical students towards CPR and CPR training at Beni-Suef University Hospital in Upper Egypt, a representative region with conditions common to LMIC settings. Participants and methods: In this cross-sectional study, a total of 205 participants (60 junior doctors and 145 medical students) responded to a self-administered questionnaire assessing their knowledge regarding basic life support (BLS) and CPR techniques in neonates, children, and adults, in addition to attitudes towards the importance and necessity of CPR and CPR training. Results: Of the 60 junior doctors that participated in the study, only 31.7% had adequate knowledge of CPR, but up to 95% reported positive attitudes towards CPR training. Among the 145 medical student participants, only 6.2% had adequate knowledge of CPR, while 91% reported positive attitudes towards training. Deficiencies in CPR knowledge were more apparent in questions related to CPR in children and neonates. Junior doctors and medical students with previous CPR training demonstrated significantly better CPR knowledge than their counterparts without prior training. A statistically significant positive correlation was detected between CPR knowledge and attitude towards CPR training among medical students (r = 0.41, p < 0.001). Conclusion: The results of this study demonstrate suboptimal and inadequate CPR knowledge among junior doctors and medical students in a representative hospital in Upper Egypt. However, participants reported overwhelmingly positive attitudes and eagerness towards the implementation of CPR training. Further research needs to be done to establish CPR skill proficiency as well as to investigate barriers to CPR training, effectiveness of available programs, and the potential implementation of such a program in Egypt and other LMICs.

Introduction: On January 1, 2014, the State of Maryland implemented the Global Budget Revenue (GBR) program. We investigate the impact of GBR on length of stay (LOS) for inpatients in emergency departments (ED) in Maryland. Methods: We used the Hospital Compare data reports from the Centers for Medicare and Medicaid Services (CMS) and CMS Cost Reports Hospital Form 2552-10 from January 1, 2012–March 31, 2016, with GBR hospitals from Maryland and hospitals from West Virginia (WV), Delaware (DE), and Rhode Island (RI). We implemented difference-in-differences analysis and investigated the impact of GBR implementation on the LOS or ED1b scores of Maryland hospitals using a mixed-effects model with a state-level fixed effect, a hospital-level random effect, and state-level heterogeneity. Results: The GBR impact estimator was 9.47 (95% confidence interval [CI], 7.06 to 11.87, p-value<0.001) for Maryland GBR hospitals, which implies, on average, that GBR implementation added 9.47 minutes per year to the time that hospital inpatients spent in the ED in the first two years after GBR implementation. The effect of the total number of hospital beds was 0.21 (95% CI, 0.089 to 0.330, p-value = 0 .001), which suggests that the bigger the hospital, the longer the ED1b score. The state-level fixed effects for WV were -106.96 (95% CI, -175.06 to -38.86, p-value = 0.002), for DE it was 6.51 (95% CI, -8.80 to 21.82, p-value=0.405), and for RI it was -54.48 (95% CI, -82.85 to -26.10, p-value<0.001). Conclusion: Our results indicate that GBR implementation has had a statistically significant negative impact on the efficiency measure ED1b of Maryland hospital EDs from January 2014 to April 2016. We also found that the significant state-level fixed effect implies that the same inpatient might experience different ED processing times in each of the four states that we studied.

Introduction: Advanced practice providers (APP), including physicians' assistants and nurse practitioners, have been increasingly incorporated into emergency department (ED) staffing over the past decade. There is scant literature examining resource utilization and the cost benefit of having APPs in the ED. The objectives of this study were to compare resource utilization in EDs that use APPs in their staffing model with those that do not and to estimate costs associated with the utilized resources. Methods: In this five-year retrospective secondary data analysis of the Emergency Department Benchmarking Alliance (EDBA), we compared resource utilization rates in EDs with and without APPs in non-academic EDs. Primary outcomes were hospital admission and use of computed tomography (CT), radiography, ultrasound, and magnetic resonance imaging (MRI). Costs were estimated using the 2014 physician fee schedule and inpatient payments from the Centers for Medicare and Medicaid Services. We measured outcomes as rates per 100 visits. Data were analyzed using a mixed linear model with repeated measures, adjusted for annual volume, patient acuity, and attending hours. We used the adjusted net difference to project utilization costs between the two groups per 1000 visits. Results: Of the 1054 EDs included in this study, 79% employed APPs. Relative to EDs without APPs, EDs staffing APPs had higher resource utilization rates (use per 100 visits): 3.0 more admissions (95% confidence interval [CI], 2.0-4.1), 1.7 more CTs (95% CI, 0.2-3.1), 4.5 more radiographs (95% CI, 2.2-6.9), and 1.0 more ultrasound (95% CI, 0.3-1.7) but comparable MRI use 0.1 (95% CI, -0.2-0.3). Projected costs of these differences varied among the resource utilized. Compared to EDs without APPs, EDs with APPs were estimated to have 30.4 more admissions per 1000 visits, which could accrue $414,717 in utilization costs. Conclusion: EDs staffing APPs were associated with modest increases in resource utilization as measured by admissions and imaging studies. [ABSTRACT FROM AUTHOR]

These clinical practice guidelines are an update of the guidelines published by the Infectious Diseases Society of America (IDSA) in 2009, prior to the 2009 H1N1 influenza pandemic. This document addresses new information regarding diagnostic testing, treatment and chemoprophylaxis with antiviral medications, and issues related to institutional outbreak management for seasonal influenza. It is intended for use by primary care clinicians, obstetricians, emergency medicine providers, hospitalists, laboratorians, and infectious disease specialists, as well as other clinicians managing patients with suspected or laboratory-confirmed influenza. The guidelines consider the care of children and adults, including special populations such as pregnant and postpartum women and immunocompromised patients. [ABSTRACT FROM AUTHOR]

Introduction: The American Heart Association recommends that post-arrest patients with evidence of ST elevation myocardial infarction (STEMI) on electrocardiogram (ECG) be emergently taken to the catheterization lab for percutaneous coronary intervention (PCI). However, recommendations regarding the utility of emergent PCI for patients without ST elevation are less specific. This review examined the literature on the utility of PCI in post-arrest patients without ST elevation compared to patients with STEMI.Methods: A systematic review of the English language literature was performed for all years to March 1, 2015 to examine the hypothesis that a percentage of post-cardiac arrest patients without ST elevation will benefit from emergent PCI as defined by evidence of an acute culprit coronary lesion.Results: Out of 1067 articles reviewed, 11 articles were identified that allowed for analysis of data to examine our study hypothesis. These studies show that patients presenting post cardiac arrest with STEMI are thirteen times more likely to be emergently taken to the catheterization lab than patients without STEMI; OR 13.8 (95% CI 4.9-39.0). Most importantly, the cumulative data show that when taken to the catheterization lab as much as 32.2% of patients without ST elevation had an acute culprit lesion requiring intervention, compared to 71.9% of patients with STEMI; OR 0.15 (95% CI 0.06-0.34).Conclusion: The results of this systematic review demonstrate that nearly one third of patients who have been successfully resuscitated from cardiopulmonary arrest without ST elevation on ECG have an acute lesion that would benefit from emergent percutaneous coronary intervention.

Introduction: Road traffic injuries are a leading killer of youth (aged 15-29) and are projected to be the 7th leading cause of death by 2030. To better understand road traffic crash locations and characteristics in the city of Baltimore, we used police and census data, to describe the epidemiology, hotspots, and modifiable risk factors involved to guide further interventions.Materials and Methods: Data on all crashes in Baltimore City from 2009 to 2013 were made available from the Maryland Automated Accident Reporting System. Socioeconomic data collected by the US CENSUS 2010 were obtained. A time series analysis was conducted using an ARIMA model. We analyzed the geographical distribution of traffic crashes and hotspots using exploratory spatial data analysis and spatial autocorrelation. Spatial regression was performed to evaluate the impact of socioeconomic indicators on hotspots.Results: In Baltimore City, between 2009 and 2013, there were a total of 100,110 crashes reported, with 1% of crashes considered severe. Of all crashes, 7% involved vulnerable road users and 12% had elderly or youth involvement. Reasons for crashes included: distracted driving (31%), speeding (6%), and alcohol or drug use (5%). After 2010, we observed an increasing trend in all crashes especially from March to June. Distracted driving then youth and elderly drivers were consistently the highest risk factors over time. Multivariate spatial regression model including socioeconomic indicators and controlling for age, gender and population size did not show a distinct predictor of crashes explaining only 20% of the road crash variability, indicating crashes are not geographically explained by socioeconomic indicators alone.Conclusion: In Baltimore City, road traffic crashes occurred predominantly in the high density center of the city, involved distracted driving and extremes of age with an increase in crashes from March to June. There was no association between socioeconomic variables where crashes occurred and hotspots. In depth analysis of how modifiable risk factors are impacted by geospatial characteristics and the built environment is warranted in Baltimore to tailor interventions. [ABSTRACT FROM AUTHOR]

Introduction: Alcohol, a common risk factor for injury, has direct toxic effects on the liver. The use of lactate clearance has been well described as an indicator of the adequacy of resuscitation in injured patients. We investigated whether acutely injured patients with positive blood alcohol content (+BAC) had less lactate clearance than sober patients.Methods: We conducted a retrospective cohort study of acutely injured patients treated at an urban Level 1 trauma centre between January 2010 and December 2012. Blood alcohol and venous lactate levels were measured on all patients at the time of arrival. Study subjects were patients transported directly from the scene of injury, who had an elevated lactate concentration on arrival (≥3.0mmol/L) and at least one subsequent lactate measurement within 24h after admission. Lactate clearance ([Lactate1-Lactate2]/Lactate1) was calculated for all patients. Chi-squared tests were used to compare values from sober and intoxicated subjects. Lactate clearance was plotted against alcohol levels and stratified by age and Injury Severity Score (ISS).Results: Serial lactate concentration measurements were obtained in 3910 patients; 1674 of them had +BAC. Patients with +BAC were younger (mean age: 36.6 [SD 14.7] vs 41.0 [SD 19.9] years [p=0.0001]), were more often male (83.4% vs 75.9% [p=0.0001]), had more minor injuries (ISS<9) (33.8% vs 27.1% [p=0.0001]), had a lower in-hospital mortality rate (1.4% vs 3.9% [p=0.0001]), but also had lower average lactate clearance (37.8% vs 47.6% [p=0.0001]). The lactate clearance of the sober patients (47.6 [SD 33.5]) was twice that of those with +BAC >400 (23.5 [SD 6.5]). Lactate clearance decreased with increasing BAC irrespective of age and ISS.Conclusions: In a large group of acutely injured patients, a dose-dependent decrease in lactate clearance was seen in those with elevated BAC.

To identify research and practice gaps to establish future research priorities to advance the detection of cognitive impairment and dementia in the emergency department (ED). Literature review and consensus-based rankings by a transdisciplinary, stakeholder task force of experts, persons living with dementia, and care partners. Scoping reviews focused on adult ED patients. Two systematic scoping reviews of 7 medical research databases focusing on best tools and approaches for detecting cognitive impairment and dementia in the ED in terms of (1) most accurate and (2) most pragmatic to implement. The results were screened, reviewed, and abstracted for relevant information and presented at the stakeholder consensus conference for discussion and ranked prioritization. We identified a total of 1464 publications and included 45 to review for accurate tools and approaches for detecting cognitive impairment and dementia. Twenty-seven different assessments and instruments have been studied in the ED setting to evaluate cognitive impairment and dementia, with many focusing on sensitivity and specificity of instruments to screen for cognitive impairment. For pragmatic tools, we identified a total of 2166 publications and included 66 in the review. Most extensively studied tools included the Ottawa 3DY and Six-Item Screener (SIS). The SIS was the shortest to administer (1 minute). Instruments with the highest negative predictive value were the SIS (vs MMSE) and the 4 A's Test (vs expert diagnosis). The GEAR 2.0 Advancing Dementia Care Consensus conference ranked research priorities that included the need for more approaches to recognize more effectively and efficiently persons who may be at risk for cognitive impairment and dementia, while balancing the importance of equitable screening, purpose, and consequences of differentiating various forms of cognitive impairment. The scoping review and consensus process identified gaps in clinical care that should be prioritized for research efforts to detect cognitive impairment and dementia in the ED setting. These gaps will be addressed as future GEAR 2.0 research funding priorities. [ABSTRACT FROM AUTHOR]

Abstract: The residency teaching model is often cited as a source of inefficiency in the healthcare system. We build a simulation model of an Emergency Department (ED) at a large urban academic hospital. Using historical data and a natural experiment involving residents in the ED, we show that residents in fact increase throughput and lower service and waiting times compared to not being there at all.

Maternal autonomy is associated with improved healthcare utilization/outcomes for mothers and babies in low- and middle-income countries. We investigated the trends in the prevalence and factors associated with maternal autonomy in Bangladesh. This cross-sectional study analyzed the Bangladesh Demographic and Health Survey for 1999-00, 2004, 2007, 2011, 2014, and 2017-18. Maternal autonomy was defined as at least one decision-making ability regarding healthcare, large household purchases, and freedom of mobility. We included 15-49-year-old mothers with at least one live-birth in the past three years. We compared the samples based on the presence of autonomy and reported the trends in prevalence (95% confidence intervals (CIs)) across the survey years. Lastly, we performed multilevel logistic regression to report prevalence odds ratios (PORs) for the associated factors. Variables investigated as potential factors included maternal age, number of children, maternal education, paternal education, current work, religion, mass media exposure, wealth quintile, place and division of residence, and survey years. The prevalence of 'any' maternal autonomy was 72.0% (95% CI: 70.5-73.5) in 1999-00 and increased to 83.8% (95% CI: 82.7-84.9) in 2017-18. In adjusted analysis, mothers with older age, higher education, work outside the home, and mass media exposure had higher odds of autonomy than their counterparts (POR > 1, p < 0.05). For instance, compared to mothers without any formal education, the odds of autonomy were significantly (p < 0.001) higher among mothers with primary (adjusted POR: 1.2, 95% CI: 1.1-1.4), secondary (adjusted POR: 1.4, 95% CI: 1.2-1.6), and college/above (adjusted POR: 1.9, 95% CI: 1.6-2.2) education. While the level of maternal autonomy has increased, a substantial proportion still do not have autonomy. Expanding educational and earning opportunities may increase maternal autonomy. Further research should investigate other ways to improve it as well., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Kibria et al.

Introduction: Chest imaging plays a prominent role in the assessment of patients with blunt trauma. Selection of the right approach at the right time is fundamental in the management of patients with blunt chest trauma . [1] A reliable, economic, bedside, and rapidly accomplished screening test can be pivotal. [2]., Objective: The aim of this study was to compare the accuracy of extended- focused assessment with sonography for trauma (E-FAST) to that of the National Emergency X-Radiography Utilisation Study (NEXUS) chest algorithm in detecting blunt chest injuries., Methods: This descriptive cross-sectional study included 50 polytrauma patients with blunt chest trauma from the emergency centre of Suez Canal University Hospital. E-FAST and computed tomography (CT) were conducted, followed by reporting of NEXUS criteria for all patients. Blinding of the E-FAST performer and CT reporter were confirmed. The results of both the NEXUS algorithm and E-FAST were compared with CT chest results., Results: The NEXUS algorithm had 100% sensitivity and 15.3% specificity, and E-FAST had 70% sensitivity and 96.7% specificity, in the detection of pneumothorax.In the detection of hemothorax, the sensitivity and specificity of the NEXUS algorithm were 90% and 7.5%, respectively, whereas E-FAST had a lower sensitivity of 80% and a higher specificity of 97.5%., Conclusion: E-FAST is highly specific for the detection of hemothorax, pneumothorax, and chest injuries compared with the NEXUS chest algorithm, which demonstrated the lowest specificity. However, the NEXUS chest algorithm showed a higher sensitivity than E-FAST and hence can be used effectively to rule out thoracic injury., Competing Interests: This work was funded by the National Institutes of Health, Fogarty International Center, Bethesda, MD (grant number, 2D43TW007296).

Background: Reducing hospital readmissions is a federal policy priority, and predictive models of hospital readmissions have proliferated in recent years; however, most such models tend to focus on the 30-day readmission time horizon and do not consider readmission over shorter (or longer) windows., Objectives: To evaluate the performance of a predictive model of hospital readmissions over three different readmission timeframes in a commercially insured population., Design: Retrospective multivariate logistic regression with an 80/20 train/test split., Participants: A total of 2,213,832 commercially insured inpatient admissions from 2016 to 2017 comprising 782,768 unique patients from the Health Care Cost Institute., Main Measures: Outcomes are readmission within 14 days, 15-30 days, and 31-60 days from discharge. Predictor variables span six different domains: index admission, condition history, demographic, utilization history, pharmacy, and environmental controls., Key Results: Our model generates C-statistics for holdout samples ranging from 0.618 to 0.915. The model's discriminative power declines with readmission time horizon: discrimination for readmission predictions within 14 days following discharge is higher than for readmissions 15-30 days following discharge, which in turn is higher than predictions 31-60 days following discharge. Additionally, the model's predictive power increases nonlinearly with the inclusion of successive risk factor domains: patient-level measures of utilization and condition history add substantially to the discriminative power of the model, while demographic information, pharmacy utilization, and environmental risk factors add relatively little., Conclusion: It is more difficult to predict distant readmissions than proximal readmissions, and the more information the model uses, the better the predictions. Inclusion of utilization-based risk factors add substantially to the discriminative ability of the model, much more than any other included risk factor domain. Our best-performing models perform well relative to other published readmission prediction models. It is possible that these predictions could have operational utility in targeting readmission prevention interventions among high-risk individuals., (© 2022.

Background: Shooting events in hospitals are increasing in frequency, with the emergency department (ED) being the most common site of such events. EDs must be prepared for shooting events, but current practices surrounding active shooter preparation are unknown., Objective: To determine what active shooter training emergency medicine physicians are receiving., Methods: A survey was developed to assess current practices around active shooter preparation in EDs. The survey was distributed to members of the American College of Emergency Physicians' Emergency Medicine Practice Research Network. All members of the Emergency Medicine Practice Research Network are currently practicing emergency medicine physicians., Results: There were 194 respondents. The most common form of training received was online (76/194), followed by lecture (50/194). Only 39 respondents had participated in an active shooter drill. Sixty-five respondents (33 percent) reported having never received any formal active shooter training., Conclusion: There is a wide array of active shooter training that emergency medicine physicians are receiving, with nearly one-third receiving no training at all.
