Response: National guidelines require EMS transportation to the nearest suitable hospital. To what extent this occurs and whether this varies by the race and ethnicity of the patient is unknown since there is little to no prior research on destination patterns of EMS-transported patients to hospitals.

Response: In 2018 serum biomarkers Glial Fibrillary Acidic Protein (GFAP) and Ubiquitin C-terminal hydrolase (UCH-L1) were FDA-approved in adults to detect abnormalities on CT scan in mild to moderate traumatic brain injury. However, they have not been approved to detect concussion and they have not been approved for use in children.
Previous studies have focused on detecting lesions on CT in more severely injured patients. However, not having brain lesions on a CT scan does not mean there is no brain injury or concussion. Therefore, this study focused on patients with concussion who looked well and likely had normal-appearing CT scans of the brain.
This study includes THREE groups of trauma patients:

Response: Minimizing care that provides little benefit to patients has become an important focus to decrease health care costs and improve the quality of care delivery. Diagnostic imaging in children is a common focus for campaigns designed to reduce overuse both in Canada and the US. There are some suggestions that there may be more overuse of care in the United States than Canada, but there has been little study in children.
We compared the use of low-value diagnostic imaging rates from four pediatric emergency departments in Ontario to 26 in the United States from 2006 to 2016. We defined low-value imaging as situations where children are discharged from an emergency department with a diagnosis for which routine use of diagnostic imaging may not be necessary, like asthma or constipation.

Response: Having a usual source of healthcare – either with a regular doctor or a medical clinic – is the best way to manage one’s health in a proactive way. Doctors and clinics can provide ongoing guidance with regard to the use of preventive medical screenings as well as the management of chronic illness. Unfortunately, a significant proportion of US adults do not have a usual source of healthcare. Also, many people often rely for their healthcare needs on a hospital emergency department, where there is neither sufficient continuity of care nor counseling for prevention.
We wanted to investigate what factors might contribute to suboptimal utilization of healthcare resources. We were particularly interested in looking at individual psychological factors that might play a role in the choices that people make when seeking healthcare. One specific psychological characteristic proved to be important in our study. That characteristic is called “threat sensitivity,” and it is measured with a simple questionnaire. People who are relatively high in threat sensitivity are prone to experience high levels of anxiety in potentially threatening situations Monitoring overdose fatalities is difficult as a result of time lags in reporting...

Response: Patients with cancer have complex care requirements and often use the emergency department. The purpose of our study was to determine whether continuity of care, cancer expertise, or both, impact outcomes among cancer patients in the emergency setting. Using administrative data we looked at adult patients with cancer who received chemotherapy or radiation therapy in the 30 days prior to an emergency department visit. Recent-onset symptomatic atrial fibrillation usually terminates spontaneously and therefore an acute cardioversion is not always necessary, as a wait-and-see approach...

Response: I’m an emergency physician, so I see first-hand how emergency department use patterns provide a lens into the status of health care delivery in the communities they serve. Troubling declines in the health of rural Americans coupled with rising rural hospital closures – with little access to alternative sites of care like urgent care – all led me to hypothesize that rural populations may be engaging with the health care system differently than their urban counterparts.
Understanding the health care use of individuals in rural areas may yield insights into addressing rural health disparities. Further, this information may help healthcare systems and policymakers to make data-driven decisions informing new models of healthcare delivery for rural communities.

Response: There is a saying that “the only winner in war is medicine”, which is the first sentence in the article. The point of that quote is that many medical advances over the last 500 years or more have been learned or propagated as a result of war.
With that as the backdrop, the purpose of our study was to provide a more comprehensive assessment of the trauma system than previous work. We accomplished this by compiling the most complete data to-date on the conflicts, using data from both Afghanistan and Iraq, and analyzing multiple interventions/policy changes simultaneously rather than in isolation. Previous work had focused primarily on single interventions and within more narrow timeframes. We wanted to expand the scope to include multiple interventions and encompass the entirety of the conflicts through the end of 2017.

Response: For many individuals with nonfatal firearm injuries, their only point of contact with the healthcare system may be the emergency department. Both hospital-based violence intervention programs and counseling and safe firearm storage have shown promise in reducing the burden of firearm injury.
In this study, one third of individuals with firearm injuries presented to non-trauma centers. Only 1 out of 5 firearm injuries were assault injuries that led to admission to trauma centers, the population most likely to receive interventions to reduce re-injury.

Response: Early resuscitation and early antibiotics have become the mainstay treatment for patients with sepsis. The time to initiation of these treatments is thought to be an important factor in patients surviving their disease; however, the independent benefits or harms of intravenous fluid resuscitation, in particular a more aggressive versus more conservative approach to this therapy, remains difficult to evaluate given the concurrent use of these therapies in hospital.
To gain a better understanding of this treatment independent of antibiotic use, we assessed intravenous fluid resuscitation by paramedics on the in-hospital mortality of patients with sepsis. By accounting for the interaction between initial systolic blood pressure and the treatment, we found that earlier resuscitation by paramedics was associated with decreased mortality in patients with low initial blood pressures but not associated with mortality for patients with normal or higher initial blood pressures.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: At least one-third of emergency department (ED) patients with acute blood clots in the lung, or pulmonary embolism (PE), are eligible for expedited discharged to home, either directly from the ED or after a short (<24 hour) period of observation. Yet in in most hospitals in the U.S. and around the world nearly all ED patients with acute PE are hospitalized. These unnecessary hospitalizations are a poor use of health care resources, tie up inpatient beds, and expose patients to the cost, inconvenience, and risk of inpatient care. The better-performing medical centers have two characteristics in common: they help their physicians identify which PE patients are candidates for outpatient care and they facilitate timely post-discharge follow-up. At Kaiser Permanente Northern California (KPNC), we have had the follow-up system in place for some time, but didn’t have a way to help our physicians sort out which patients with acute PE would benefit from home management.
To correct this, we designed a secure, web-based clinical decision support system that was integrated with the electronic health record. When activated, it presented to the emergency physician the validated PE Severity Index, which uses patient demographics, vital signs, examination findings, and past medical history to classify patients into different risk strata, correlated with eligibility for home care. To make use of the PE Severity Index easier and more streamlined for the physician, the tool drew in information from the patient’s comprehensive medical records to accurately auto-populate the PE Severity Index. The tool then calculated for the physician the patient’s risk score and estimated 30-day mortality, and also offered a site-of-care recommendation, for example, “outpatient management is often possible.” The tool also reminded the physician of relative contraindications to outpatient management. At the time, only 10 EDs in KPNC had an on-site physician researcher, who for this study served as physician educator, study promotor, and enrollment auditor to provide physician-specific feedback. These 10 EDs functioned as the intervention sites, while the other 11 EDs within KPNC served as concurrent controls. Our primary outcome was the percentage of eligible ED patients with acute PE who had an expedited discharge to home, as defined above.
During the 16-month study period (8-month pre-intervention and 8-months post-intervention), we cared for 1,703 eligible ED patients with acute PE. Adjusted home discharge increased at intervention sites from 17% to 28%, a greater than 60% relative increase. There were no changes in home discharge observed at the control sites (about 15% throughout the 16-month study). The increase in home discharge was not associated with an increase in short-term return visits or major complications.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Systematic triage has been implemented worldwide with different triage scales in use all over the world. Prior to the introduction of formalised triage, patients were prioritised based on clinical assumption.
After the introduction of formalised triage only a few studies have assessed agreement between formal and informal triage. Additionally, the majority of formalised triage scales are supported by limited and often insufficient evidence. This is troublesome since formalised triage forces clinicians to follow an algorithm rather than use their experience and clinical judgement. During my own residency at a Danish Emergency ward I was often contacted by the nurse performing formalised triage telling me that a patient she was assessing scored to be very acute (high triage level), but that she didn’t believe that to be the case. In order for her to prioritise the patient to a lower (less acute) triage level the patient had to be assessed by a doctor.
Very often my colleagues and I would agree with the nurse in that the scoring was to high, and we therefore had to overrule the formalised triage decision. In cases like these you ask yourself whether or not we are using the most effective and best form of triage for initial patient sorting.
Our study found that agreement between formalised triage and a quick clinical assessment in the form of Eyeball triage is poor. It also suggest that eyeball triage better predicts those at highest risk of death within 48-hours and 30 days after assessment.

Response: Head CT scan is one of the most commonly used imaging protocols besides chest x-ray. They are used for patients with symptoms suggesting stroke, rise in intracranial pressure or head trauma. These manifest in findings like intracranial haemorrhage, midline shift or fracture.
Scans with these critical findings need to be read immediately. But radiologists evaluate the scans on first-come-first-serve basis or based on stat/routine markers set by clinicians. If the scans with critical findings are somehow pushed to the top of radiologists’ work list, it could substantially decrease time to diagnosis and therefore decrease mortality and morbidity associated with stroke/head trauma.

Response: 450,000 children present to U.S emergency departments each year for evaluation of head trauma. Physicians obtain head computed tomography (CT) scans in 37%-50% of these patients, with less than 10% showing evidence of traumatic brain injury and only 0.2% that require neurosurgical treatment.
In order to avoid unnecessary CT scans and to limit radiation exposure, the Pediatric Emergency Care Applied Research Network (PECARN) developed clinical prediction rules that consist of 6 readily available factors that can be assessed from the history and physical examination. If none of these risk factors are present, a CT scan is not indicated.
If either of 2 high risk factors such as signs of a skull fracture are present, CT scanning is indicated.
If 1 or 2 non-high risk factors are present, then either CT scanning or observation are recommended, depending on considerations such as parental preference, clinician experience and/or symptom progression.
In this study we designed a parent decision aid, “Head CT Choice” to educate the parent about the difference between a concussion – which does not show up on a CT scan – and a more serious brain injury causing bleeding in or around the brain. The decision aid also shows parents their child’s risk for a serious brain injury – less than 1% risk in the majority of patients in our trial – what to observe their child at home for should they opt not to obtain a CT scan, and the advantages and disadvantages of CT scanning versus home observation.
In our trial, we did not observe a difference in the rate of head CT scans obtained in the ED but did find that parents who were engaged in shared decision-making using Head CT Choice were more knowledgeable about their child’s risk for serious brain injury, has less difficulty making the decision because they were clearer about the advantages and disadvantages of the diagnostic options, and were more involved in decision-making by their physician. Parents also less frequently sought additional testing for their child within 1 week of the emergency department visit.

Response: Patients with blood clots in the lungs (pulmonary embolism) (PE) are routinely admitted to the hospital for blood thinning medications in the United States. However, evidence from other countries has shown that with appropriate risk stratification patients may be safe for outpatient treatment for their PE.
Our study is the largest prospective management study in the US to evaluate home treatment of patients with acute pulmonary embolism. We enrolled 200 patients and after risk stratification with the PE severity index score, leg ultrasounds and echocardiograms performed in the emergency department, patients were treated with blood thinning medications at home with routine outpatient follow up.
During the 90 day follow up period we found only one patient suffered a bleeding event after a traumatic injury, without any cases of recurrent symptomatic blood clots or death.

Response: Medical errors harm thousands of patients per year. There’s already a lot we know about systems errors - the ways that care delivery can go wrong. We know less about cognitive errors, or the ways in which doctors think that can lead to bad outcomes. An Emergency Department can feel particularly vulnerable to this type of errors - it’s a chaotic environment with patients in various states of illness, many unaccompanied, without records, or too ill to communicate well.
An Emergency Department with trainee physicians can feel even more chaotic - even though they are supervised by staff physicians, resident physicians in their first few months to years of training have not yet accumulated the same level of knowledge and experience as longer-tenured doctors. Errors that get made on the hospital floor are errors of information processing - physicians have the right information, they just don’t always do the right thing with it. We wanted to know what kinds of errors get made in an Emergency Department with trainees. Are the errors related to the chaos and an inability to obtain reliable information from patients? Are they related to the trainees not having enough knowledge and experience? Or are they like the errors that get made on an inpatient floor?
Our study found that the most frequent type of errors were errors of information processing - just like on the hospital floors. The most common types of errors we saw were physicians settling on a diagnosis prematurely and weighing the importance of findings incorrectly. Patients with abdominal problems had the highest number of errors in our study. Patients with certain risk factors, such as psychiatric disease or substance abuse, seemed to be particularly prone to errors.

Response: Ketamine is being increasingly used in the emergency department (ED) for a variety of conditions, including as an analgesic. While its usage continues to increase, there are limited studies evaluating ketamine as an analgesic in the emergency department.
Most of the studies evaluating ketamine utilized it as an adjunct to an opioid, however, multiple recommendations on blogs and other websites recommend ketamine as a single agent. The purpose of the meta-analysis was to compare the analgesic effect of ketamine compared to an opioid in adult patients presenting with acute pain to the ED.
In this study, we found that ketamine was non-inferior to opioids. We also found that the number of severe adverse events to be similar between both groups.

Response: The past 20 years in shaping the Helsinki model in stroke thrombolysis have proven that we can be very fast in examining the patient, completing the imaging and starting thrombolytic therapy. This is a university hospital center that receives roughly three stroke suspects per day for evaluation of recanalization therapies. Already seven years ago we were able to push the median ’door-to-needle’ time permanently below 20 minutes. What we had not been monitoring was how well we had kept up the accuracy of our emergengy department (ED) diagnostic process. Prehospital emergency medical services (EMS) have been trained to focus on suspecting thrombolysis-eligible stroke and we usually get also pre-notifications of arriving stroke code patients during transportation, but the diagnosis on admission is an independent clinical judgment as the CT findings are largely nondiagnostic for acute changes.
The admission evaluation of suspected acute stroke is therefore a decisive neurologic checkpoint, building the success of acute treatments such as recanalization therapy, but is complicated by differential diagnosis between true manifestations of stroke and numerous mimicking conditions. Although we have invested a lot on training and standardized ED procedures, time pressure and therapy-geared expectations may blur the diagnostic process.
With this background, we embarked on an in-depth-analysis of the admission and final diagnoses of stroke code patients, as well as misdiagnoses, immediate treatment decisions and their consequences.

Response: Bicycling is a great way for families to get outside and be active together, but certain precautions need to be taken to keep everyone safer. This study looked at bicycle-related injuries among children age 5-17 years treated in hospital emergency departments in the United States from 2006 through 2015 and found that, despite a decrease in the rate of injuries over the 10-year study period, there were still more than 2.2 million injuries. This averages 608 cases per day or 25 every hour.
The majority of injuries involved children 10 to 14 years of age (46%) and boys (72%). The most commonly injured body region was the upper extremities (36%), followed by the lower extremities (25%), face (15%), and head and neck (15%). The most common types of injury were bruises and scrapes (29%) and cuts (23%). Overall, traumatic brain injuries (TBIs) represented 11% of total injuries and were most common among patients 10-14 years of age (44%). About 4% of patients were hospitalized.
Injuries most frequently occurred in the street (48%) or at home (37%). Helmet use at the time of injury was associated with a lower likelihood of head and neck injuries and hospitalizations, but there was no significant change in the rate of injury among helmet users over the study period. Motor vehicle involvement increased the odds of bicycle-related TBIs and injury-related hospitalizations.

We chose to study Stress Echocardiography and Coronary CT Angiography, two exams that have not been compared directly in this population. We found that Stress Echocardiography was able to discharge a higher proportion of patients in a shorter amount of time as compared to Coronary CTA.

Response: Opioid use disorder (OUD) and opioid overdose deaths are a rapidly increasing public health crisis. In this paper, we review and synthesize current evidence on the identification, management and transition of patients from the emergency department (ED) to the outpatient setting and present several key recommendations.
For patients identified to haveOpioid use disorder, we recommend ED-initiated mediation-assisted therapy (MAT) with buprenorphine, an opioid agonist. Current evidence suggests that it safe and effective, leading to improved patient outcomes. At the same time, a coordinated care plan should be put into motion which combines MAT with a rapid transition to outpatient care, preferably within 72 hours of ED evaluation. Where possible, a warm handoff is preferred, as it has been shown in other settings to improve follow-up. Outpatient care should combine MAT, psychological interventions and social support/case management in order to maximize impact

Response: With increasing air travel, in-flight medical emergencies have increased and physicians on commercial airline flights are routinely asked to volunteer assistance. A study presented this week at the annual meeting of The Society for Academic Emergency Medicine (SAEM) examined physician performance during practice simulations of in-flight medical emergencies with use of a smartphone app, airRx.
In the unique study, cases based on commonly occurring in-flight medical emergencies were portrayed in a mockup of the airline cabin setting. Actors portrayed patients, family members, seat neighbors and flight attendants. Resident physicians in non-emergency specialties were asked to assist as if they were volunteering in actual medical emergencies.
The study utilized airRx, the mobile app developed to help physicians and other medical personnel volunteering during in-flight medical events. The airRx app enables healthcare professionals to access 23 scenarios of the most common medical emergencies, with concise treatment algorithms and reference information to help evaluate and treat the patient.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Migraine and other recurrent headache disorders disproportionately affect otherwise healthy, middle-aged people, particularly women, and are a leading cause of suffering and disability.
Accurate epidemiologic information is vital for providers, researchers and policy makers. In this paper we surveyed the most recent data from population-based studies in the United States to assess the burden and impact of these conditions. Our search included such sources as the National Health Interview Study (NHIS), the National Hospital Ambulatory Medical Care Survey (NHAMCS) and the National Ambulatory Medical Care Survey (NAMCS).
We found that the prevalence and burden of self-reported migraine and other severe headache has remained stable but high in the past 19 years, affecting roughly 1 out of every 6 Americans (15.3%) and 1 in 5 women (20.7%) over a 3-month period.
Among other findings was that headache is proportionately more burdensome those in middle age (elderly also), those who are unemployed and those who are disabled or who have low family income. Headache represents roughly 3% of all annual emergency department visits.
