The Effect of Language on the Decision to Image in the Evaluation of Atraumatic Headache.

BACKGROUND: Patients with limited English proficiency seen in the emergency department (ED) experience lower quality of care and higher diagnostic resource utilization unless they are evaluated in their own language. Despite a low rate of serious pathology identified and the availability of guidelines to direct its use, computed tomography (CT) is commonly used to evaluate atraumatic headache in the ED. OBJECTIVE: Our aim was to determine whether Spanish-speaking patients with atraumatic headache were more likely than their English-speaking counterparts to undergo head CT, and whether evaluation by a clinician who passed a Spanish proficiency test mitigated this difference. METHODS: This retrospective observational study used electronic health record data of adult patients presenting with atraumatic headache to a level I trauma center during a 2-year period. Spanish-language testing of clinicians consisted of a brief, unvalidated, in-person, nonmedical verbal test administered by human resources staff. RESULTS: A total of 3030 patients with atraumatic headache were identified; 1437 were English speaking and 1593 were Spanish speaking. Spanish-speaking patients were older (48.3 vs. 41.9 years), more likely to be women (68.8% vs. 60.5%), and more likely to undergo head CT (31.8% vs. 26.4%). Evaluation by a clinician who passed the Spanish proficiency test had no significant influence on the likelihood of head CT for Spanish-speaking patients after controlling for confounding variables (adjusted odds ratio 0.95; 95% CI 0.75-1.20). CONCLUSIONS: Spanish-speaking patients are more likely to undergo head CT when evaluated for atraumatic headache than English-speaking patients. Evaluation by a clinician who passed a brief Spanish proficiency test did not mitigate this disparity.

Process and Impact of Development of an Adolescent Emergency Psychiatry Unit at a Large Urban Hospital.

OBJECTIVES: Boarding of adolescent patients with mental health concerns requiring ongoing observation and treatment is of increasing concern across US emergency departments. The objective was a proof of concept of developing an adolescent psychiatric emergency unit and assessment of the impact of this unit on lengths of stay (LOS). METHODS: We describe the creation of the unit designed to allow safe assessment and boarding of patients, and appropriate interventions and services, while arranging transfer to inpatient facility or safe discharge home. Using a precreation and postcreation analysis and comparison with a similar facility that did not create such a unit, we utilized linear regression to investigate the primary outcome of total length of stay and secondary outcomes of psychiatric emergency department and pediatric emergency department length of stay for both unit-eligible patients and all patients. RESULTS: The overall length of stay was not associated with a statistically significant change for unit-eligible patients; however, there was a significant decrease in the pediatric emergency department LOS for unit-eligible patients. This was associated with a decrease in beds lost to boarding in the pediatric emergency department of 544 hours per month. CONCLUSIONS: Creation of an adolescent psychiatric emergency unit without allotment of significant additional resources is an option to decrease pediatric emergency department boarding times for adolescent patients requiring ongoing emergent therapy for mental health concerns.

Epidemiology of Admissions From the Emergency Department Among Febrile Infants Younger Than 90 Days in the United States, 2002 to 2012.

BACKGROUND AND OBJECTIVES: Febrile infants younger than 90 days are often subjected to invasive diagnostic evaluation and hospitalization to monitor for serious bacterial infection (SBI) despite recent changes in SBI risk and advances in diagnostics. Nationwide provider practices, over time, are unknown for this group. Our objective was to determine the likelihood of admission and associated complications of care for such infants, particularly those at lowest risk for SBI. METHODS: This is a retrospective cohort study including multisite emergency department (ED) visits using administrative data from the Pediatric Emergency Care Applied Research Network Core Data Project. We examined uncomplicated febrile infants younger than 90 days seen in the ED from 2002 to 2012 who did not have an explicit infectious diagnosis, critical illness, or chronic condition. RESULTS: We identified 38,224 infants, among whom, 11,600 (31%) were admitted. We observed a 3% increase in ED admission every year during the study period (P < 0.05). Age less than 30 days and black race were independent predictors of admission (P < 0.01). We identified 227 complications of care in the ED. Among those with a specified cause, 49% were attributed to antibiotic use or procedures related to the diagnosis and empiric treatment of suspected infection. CONCLUSIONS: Despite the decreasing risk of SBI and diagnostic advances during the study period, the odds of hospital admission increased for febrile infants at low risk for sepsis. We also provide first data on therapeutic and diagnostic test-related adverse events in this setting. These data provide further justification for a consensus guideline on management of such infants.

Impact of individual clinical outcomes on trial participants' perspectives on enrollment in emergency research without consent.

BACKGROUND: Evidence suggests that patients are generally accepting of their enrollment in trials for emergency care conducted under exception from informed consent. It is unknown whether individuals with more severe initial injuries or worse clinical outcomes have different perspectives. Determining whether these differences exist may help to structure post-enrollment interactions. METHODS: Primary clinical data from the Progesterone for the Treatment of Traumatic Brain Injury trial were matched to interview data from the Patients' Experiences in Emergency Research-Progesterone for the Treatment of Traumatic Brain Injury study. Answers to three key questions from Patients' Experiences in Emergency Research-Progesterone for the Treatment of Traumatic Brain Injury study were analyzed in the context of enrolled patients' initial injury severity (initial Glasgow Coma Scale and Injury Severity Score) and principal clinical outcomes (Extended Glasgow Outcome Scale and Extended Glasgow Outcome Scale relative to initial injury severity). The three key questions from Patients' Experiences in Emergency Research-Progesterone for the Treatment of Traumatic Brain Injury study addressed participants' general attitude toward inclusion in the Progesterone for the Treatment of Traumatic Brain Injury trial (general trial inclusion), their specific attitude toward being included in Progesterone for the Treatment of Traumatic Brain Injury trial under the exception from informed consent (personal exception from informed consent enrollment), and their attitude toward the use of exception from informed consent in the Progesterone for the Treatment of Traumatic Brain Injury trial in general (general exception from informed consent enrollment). Qualitative analysis of interview transcripts was performed to provide contextualization and to determine the extent to which respondents framed their attitudes in terms of clinical experience. RESULTS: Clinical data from Progesterone for the Treatment of Traumatic Brain Injury trial were available for all 74 patients represented in the Patients' Experiences in Emergency Research-Progesterone for the Treatment of Traumatic Brain Injury study (including 46 patients for whom the surrogate was interviewed due to the patient's cognitive status or death). No significant difference was observed regarding acceptance of general trial inclusion or acceptance of general exception from informed consent enrollment between participants with favorable neurological outcomes and those with unfavorable outcomes relative to initial injury. Agreement with personal enrollment in Progesterone for the Treatment of Traumatic Brain Injury trial under exception from informed consent, however, was significantly higher among participants with favorable outcomes compared to those with unfavorable outcomes (89% vs 59%, p = 0.003). There was also a statistically significant relationship between more severe initial injury and increased acceptance of personal exception from informed consent enrollment ( p = 0.040) or general exception from informed consent use ( p = 0.034) in Progesterone for the Treatment of Traumatic Brain Injury trial. Many individuals referenced personal experience as a basis for their attitudes, but these references were not used to support negative views. CONCLUSION: Patients and surrogates of patients with unfavorable clinical outcomes were somewhat less accepting of their own inclusion in the Progesterone for the Treatment of Traumatic Brain Injury trial under exception from informed consent than were patients or surrogates of patients with favorable clinical outcomes. These findings suggest a need to identify optimal strategies for communicating with patients and their surrogates regarding exception from informed consent enrollment when clinical outcomes are poor.

Validating the Use of ICD-9 Code Mapping to Generate Injury Severity Scores.

The Injury Severity Score (ISS) is a measure of injury severity widely used for research and quality assurance in trauma. Calculation of ISS requires chart abstraction, so it is often unavailable for patients cared for in nontrauma centers. Whether ISS can be accurately calculated from International Classification of Diseases, Ninth Revision (ICD-9) codes remains unclear. Our objective was to compare ISS derived from ICD-9 codes with those coded by trauma registrars. This was a retrospective study of patients entered into 9 U.S. trauma registries from January 2006 through December 2008. Two computer programs, ICDPIC and ICDMAP, were used to derive ISS from the ICD-9 codes in the registries. We compared derived ISS with ISS hand-coded by trained coders. There were 24,804 cases with a mortality rate of 3.9%. The median ISS derived by both ICDPIC (ISS-ICDPIC) and ICDMAP (ISS-ICDMAP) was 8 (interquartile range [IQR] = 4-13). The median ISS in the registry (ISS-registry) was 9 (IQR = 4-14). The median difference between either of the derived scores and ISS-registry was zero. However, the mean ISS derived by ICD-9 code mapping was lower than the hand-coded ISS in the registries (1.7 lower for ICDPIC, 95% CI [1.7, 1.8], Bland-Altman limits of agreement = -10.5 to 13.9; 1.8 lower for ICDMAP, 95% CI [1.7, 1.9], limits of agreement = -9.6 to 13.3). ICD-9-derived ISS slightly underestimated ISS compared with hand-coded scores. The 2 methods showed moderate to substantial agreement. Although hand-coded scores should be used when possible, ICD-9-derived scores may be useful in quality assurance and research when hand-coded scores are unavailable.

Patients' perspectives of enrollment in research without consent: the patients' experiences in emergency research-progesterone for the treatment of traumatic brain injury study.

OBJECTIVE: Research in acute illness often requires an exception from informed consent. Few studies have assessed the views of patients enrolled in exception from informed consent trials. This study was designed to assess the views of patients and their surrogates of exception from informed consent enrollment within the context of a randomized, placebo-controlled trial of an investigational agent for traumatic brain injury. DESIGN: Interactive interview study. SETTING: Nested within the Progesterone for the Treatment of Traumatic Brain Injury trial, a Phase III randomized controlled trial in acute traumatic brain injury. SUBJECTS: Patients and surrogates (for patients incapable of being interviewed) enrolled in Progesterone for the Treatment of Traumatic Brain Injury under exception from informed consent at 12 sites. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Interviews focused on respondents' acceptance of exception from informed consent enrollment in Progesterone for the Treatment of Traumatic Brain Injury, use of placebo and randomization, understanding of major study elements, and views regarding regulatory protections. Descriptive statistical analysis was performed; textual data were analyzed thematically. Eighty-five individuals were interviewed. Eighty-four percent had positive attitudes toward Progesterone for the Treatment of Traumatic Brain Injury inclusion. Seventy-eight percent found their inclusion under exception from informed consent acceptable, and 72% found use of exception from informed consent in Progesterone for the Treatment of Traumatic Brain Injury acceptable in general. Only two respondents clearly disagreed with both personal and general exception from informed consent enrollment. The most common concerns (26%) related to absence of consent. Eighty percent and 92% were accepting of placebo use and randomization, respectively. Although there were few black respondents (n = 11), they were less accepting of personal exception from informed consent enrollment than white respondents (55% vs 83%; p = 0.0494). CONCLUSIONS: Acceptance of exception from informed consent in this placebo-controlled trial of an investigational agent was high and exceeded acceptance among community consultation participants. Exception from informed consent enrollment appears generally consistent with patients' preferences.

Association of Residency Applicants' Hobbies and Subsequent Technical Proficiency Ratings as General Surgery Chief Residents: A Multi-Institutional Study.

OBJECTIVE: To determine whether participation in certain hobbies (e.g., participation in sports, playing musical instruments, or other hobbies requiring fine motor skills), preresidency, are associated with higher technical skills ratings at the time of residency graduation. DESIGN: Faculty members from 14 general surgery residency programs scored individual graduates from 2017 to 2020 on their technical skills using a 5-point Likert scale. Hobbies for these residents were collected from their Electronic Residency Application Service (ERAS) data. A single reviewer classified each ERAS hobby into predefined categories including musical instruments, sports requiring hand-eye coordination, team sports, and activities necessitating hand-eye coordination. Spearman correlation coefficients were calculated for the relationship between each category of hobby-as well as the total number of hobbies in each category-and the outcome of surgical faculty ratings of residents' technical surgical skills during their last year of residency. A proportional odds model including the above predictive variables was also fit to the data. SETTING: Fourteen general surgery residency programs. PARTICIPANTS: General surgery residency graduates from 14 different programs from 2017 to 2020. RESULTS: There were 296 residents across 14 institutions. The average ranking of residents' technical skills was 3.24 (SD 1.1). A total of 40% of residents played sports involving hand-eye coordination, 31% played team sports, 28% participated in nonsport hobbies that require eye-hand coordination, and 20% played musical instruments. Correlation coefficients were not statistically significant for any of the categories. In the proportional odds model, none of the variables were associated with statistically significant increased odds of a higher technical skills rating. CONCLUSIONS: There was no correlation between general surgery chief residents' technical skills as rated by faculty, and self-reported pre-residency hobbies on the ERAS application. These findings suggest such hobbies prior to residency are unlikely to predict future technical skills prowess.

Predicting ambulance time of arrival to the emergency department using global positioning system and Google maps.

OBJECTIVE: To derive and validate a model that accurately predicts ambulance arrival time that could be implemented as a Google Maps web application. METHODS: This was a retrospective study of all scene transports in Multnomah County, Oregon, from January 1 through December 31, 2008. Scene and destination hospital addresses were converted to coordinates. ArcGIS Network Analyst was used to estimate transport times based on street network speed limits. We then created a linear regression model to improve the accuracy of these street network estimates using weather, patient characteristics, use of lights and sirens, daylight, and rush-hour intervals. The model was derived from a 50% sample and validated on the remainder. Significance of the covariates was determined by p < 0.05 for a t-test of the model coefficients. Accuracy was quantified by the proportion of estimates that were within 5 minutes of the actual transport times recorded by computer-aided dispatch. We then built a Google Maps-based web application to demonstrate application in real-world EMS operations. RESULTS: There were 48,308 included transports. Street network estimates of transport time were accurate within 5 minutes of actual transport time less than 16% of the time. Actual transport times were longer during daylight and rush-hour intervals and shorter with use of lights and sirens. Age under 18 years, gender, wet weather, and trauma system entry were not significant predictors of transport time. Our model predicted arrival time within 5 minutes 73% of the time. For lights and sirens transports, accuracy was within 5 minutes 77% of the time. Accuracy was identical in the validation dataset. Lights and sirens saved an average of 3.1 minutes for transports under 8.8 minutes, and 5.3 minutes for longer transports. CONCLUSIONS: An estimate of transport time based only on a street network significantly underestimated transport times. A simple model incorporating few variables can predict ambulance time of arrival to the emergency department with good accuracy. This model could be linked to global positioning system data and an automated Google Maps web application to optimize emergency department resource use. Use of lights and sirens had a significant effect on transport times.

Evaluation of a novel pediatric appendicitis pathway using high- and low-risk scoring systems.

OBJECTIVES: This study aimed to determine the test characteristics of a pathway for pediatric appendicitis and its effects on emergency department (ED) length of stay, imaging, and admissions. METHODS: Children age 3 to 18 years with suspicion for appendicitis at 1 tertiary care ED were prospectively enrolled, using validated low- and high-risk scoring systems incorporating history, physical examination, and white blood cell count. Low-risk patients were discharged or observed in the ED. High-risk patients were admitted. Those meeting neither low-risk nor high-risk criteria were evaluated by surgery, with imaging at their discretion. Chart review or telephone follow-up was conducted 2 weeks after the visit. A retrospective study before and after was also performed. Charts of a random sample of patients evaluated for appendicitis in the 8 months before and after the pathway implementation were reviewed. RESULTS: Appendicitis was diagnosed in 65 of 178 patients. Of those with appendicitis, 63 were not low-risk (sensitivity, 96.9%; specificity, 40.7%). The high-risk criteria had a sensitivity of 75.3% and specificity of 75.2%. We reviewed 292 visits before and 290 after the pathway implementation. Emergency department length of stay was similar (253 minutes before vs 257 minutes after, P = 0.77). Computed tomography was used in 12.7% of visits before and 6.9% of visits after (P = 0.02). Use of ultrasound was not significantly different (47.3% vs 53.7%). Admission rates were not significantly different (45.5% vs 42.7%). CONCLUSIONS: The low-risk criteria had good sensitivity in ruling out appendicitis. The high-risk criteria could be used to guide referral or admission. Neither outperformed the a priori judgment of experienced providers.

Trial Participation and Outcomes Among English-Speaking and Spanish-Speaking Patients With Appendicitis Randomized to Antibiotics: A Secondary Analysis of the CODA Randomized Clinical Trial.

Importance: Spanish-speaking participants are underrepresented in clinical trials, limiting study generalizability and contributing to ongoing health inequity. The Comparison of Outcomes of Antibiotic Drugs and Appendectomy (CODA) trial intentionally included Spanish-speaking participants. Objective: To describe trial participation and compare clinical and patient-reported outcomes among Spanish-speaking and English-speaking participants with acute appendicitis randomized to antibiotics. Design, Setting, and Participants: This study is a secondary analysis of the CODA trial, a pragmatic randomized trial comparing antibiotic therapy with appendectomy in adult patients with imaging-confirmed appendicitis enrolled at 25 centers across the US from May 1, 2016, to February 28, 2020. The trial was conducted in English and Spanish. All 776 participants randomized to antibiotics are included in this analysis. The data were analyzed from November 15, 2021, through August 24, 2022. Intervention: Randomization to a 10-day course of antibiotics or appendectomy. Main Outcomes and Measures: Trial participation, European Quality of Life-5 Dimensions (EQ-5D) questionnaire scores (higher scores indicating a better health status), rate of appendectomy, treatment satisfaction, decisional regret, and days of work missed. Outcomes are also reported for a subset of participants that were recruited from the 5 sites with a large proportion of Spanish-speaking participants. Results: Among eligible patients 476 of 1050 Spanish speakers (45%) and 1076 of 3982 of English speakers (27%) consented, comprising the 1552 participants who underwent 1:1 randomization (mean age, 38.0 years; 976 male [63%]). Of the 776 participants randomized to antibiotics, 238 were Spanish speaking (31%). Among Spanish speakers randomized to antibiotics, the rate of appendectomy was 22% (95% CI, 17%-28%) at 30 days and 45% (95% CI, 38%-52%) at 1 year, while in English speakers, these rates were 20% (95% CI, 16%-23%) at 30 days and 42% (95% CI 38%-47%) at 1 year. Mean EQ-5D scores were 0.93 (95% CI, 0.92-0.95) among Spanish speakers and 0.92 (95% CI, 0.91-0.93) among English speakers. Symptom resolution at 30 days was reported by 68% (95% CI, 61%-74%) of Spanish speakers and 69% (95% CI, 64%-73%) of English speakers. Spanish speakers missed 6.69 (95% CI, 5.51-7.87) days of work on average, while English speakers missed 3.76 (95% CI, 3.20-4.32) days. Presentation to the emergency department or urgent care, hospitalization, treatment dissatisfaction, and decisional regret were low for both groups. Conclusions and Relevance: A high proportion of Spanish speakers participated in the CODA trial. Clinical and most patient-reported outcomes were similar for English- and Spanish-speaking participants treated with antibiotics. Spanish speakers reported more days of missed work. Trial Registration: ClinicalTrials.gov Identifier: NCT02800785.

Characteristics Associated With Outstanding General Surgery Residency Graduate Performance, as Rated by Surgical Educators.

Importance: Characteristics of outstanding graduating surgical residents are currently undefined. Identifying these qualities may be important in guiding resident selection and resident education. Objective: To determine characteristics that are most strongly associated with being rated as an outstanding graduating surgical resident. Design, Setting, and Participants: The multi-institutional study had 3 phases. First, an expert panel developed a list of characteristics embodied by top graduating surgical residents. Second, groups of faculty from 14 US general-surgery residency programs ranked 2017 through 2020 graduates into quartiles of overall performance. Third, faculty evaluated their graduates on each characteristic using a 5-point Likert scale. Data were analyzed using Spearman rank-order correlation to identify which individual characteristics were associated with overall graduate performance. A least absolute shrinkage and selection operator (LASSO) ordinal regression was performed to select a parsimonious model to predict the outcome of overall performance rating from individual characteristic scores. Main Outcome and Measures: Surgical educators' rankings of general surgery residency graduates' overall performance. Results: Fifty faculty from 14 US residency programs with a median of 13 (range, 5-30) years of surgical education experience evaluated 297 general surgery residency graduates. Surgical educators identified 21 characteristics that they believed outstanding graduating surgical residents possessed. Two hundred ninety-seven surgical residency graduates were evaluated. Higher scores in every characteristic correlated with better overall performance. Characteristics most strongly associated with higher overall performance scores were surgical judgment (r = 0.728; P < .001), leadership (r = 0.726; P < .001), postoperative clinical skills (r = 0.715; P < .001), and preoperative clinical skills (r = 0.707; P < .001). The remainder of the characteristics were moderately associated with overall performance. The LASSO regression model identified 3 characteristics from which overall resident performance could be accurately predicted without measuring other qualities: surgical judgment (odds ratio [OR] per 1 level of 5-level Likert scale OR, 1.27; 95% CI, 1.03-1.51), leadership (OR, 1.27; 95% CI, 1.06-1.48), and medical knowledge (OR, 1.16; 95% CI, 1.01-1.33). Conclusions and Relevance: All individual characteristics identified by surgical educators as being qualities of outstanding graduating surgical residents were positively associated with overall graduate performance. Surgical judgment and leadership skills had the strongest individual associations. Assessment of only 3 qualities (surgical judgment, leadership, and medical knowledge) were required to predict overall resident performance ratings. These findings highlight the importance of developing specific surgical judgment and leadership skills curricula and assessments during surgical residency.

Trauma in the neighborhood: a geospatial analysis and assessment of social determinants of major injury in North America.

OBJECTIVES: We sought to identify and characterize areas with high rates of major trauma events in 9 diverse cities and counties in the United States and Canada. METHODS: We analyzed a prospective, population-based cohort of injured individuals evaluated by 163 emergency medical service agencies transporting patients to 177 hospitals across the study sites between December 2005 and April 2007. Locations of injuries were geocoded, aggregated by census tract, assessed for geospatial clustering, and matched to sociodemographic measures. Negative binomial models were used to evaluate population measures. RESULTS: Emergency personnel evaluated 8786 major trauma patients, and data on 7326 of these patients were available for analysis. We identified 529 (13.7%) census tracts with a higher than expected incidence of major trauma events. In multivariable models, trauma events were associated with higher unemployment rates, larger percentages of non-White residents, smaller percentages of foreign-born residents, lower educational levels, smaller household sizes, younger age, and lower income levels. CONCLUSIONS: Major trauma events tend to cluster in census tracts with distinct population characteristics, suggesting that social and contextual factors may play a role in the occurrence of significant injury events.

Pediatric educational needs assessment for urban and rural emergency medical technicians.

OBJECTIVE: The objective of the study was to identify past experiences, present needs, barriers, and desired methods of training for urban and rural emergency medical technicians. METHODS: This 62-question pilot-tested written survey was administered at the 2008 Oregon EMS and 2009 EMS for Children conferences. Respondents were compared with registration lists and the state emergency medical services (EMS) database to assess for nonresponder bias. Agencies more than 10 miles from a population of 40,000 were defined as rural. RESULTS: Two hundred nineteen (70%) of 313 EMS personnel returned the surveys. Respondents were 3% first responders, 27% emergency medical technician basics, 20% intermediates, and 47% paramedics. Sixty-eight percent were rural, and 32% were urban. Sixty-eight percent reported fewer than 10% pediatric transports. Overall, respondents rated their comfort caring for pediatric patients as 3.1 on a 5-point Likert scale (95% confidence interval, 3.1-3.2). Seventy-two percent reported a mean rating of less than "comfortable" (4 on the scale) across 17 topics in pediatric care, which did not differ by certification level. Seven percent reported no pediatric training in the last 2 years, and 76% desired more. The "quality of available trainings" was ranked as the most important barrier to training; 26% of rural versus 7% of urban EMS personnel ranked distance as the most significant barrier (P < 0.01). Fifty-one percent identified highly realistic simulations as the method that helped them learn best. In the past 2 years, 19% had trained on a highly realistic pediatric simulator. One to 3 hours was the preferred duration for trainings. CONCLUSIONS: Except for distance as a barrier, there were no significant differences between urban and rural responses. Both urban and rural providers desire resources, in particular, highly realistic simulation, to address the infrequency of pediatric transports and limited training.

Basic life support instructor training: comparison of instructor-led and self-guided training.

In this randomized trial, the authors compared the instructional quality of instructor candidates trained in instructional methods through an Internet-based versus a traditional classroom-led version of the American Heart Association Core Instructor Course. The self-guided, Internet-based group had significantly higher posttest scores than did the traditional instructor-led group (although not when adjusted for pretest scores). The Internet-based group scores changed from 54% to 67%, exceeding the a priori definition of 8% as a minimally practically significant improvement (instructor-led group scores changed from 49% to 53%). The Internet-based course appeared to be a suitable alternative to the traditional course.

Acute Demyelinating Encephalomyelitis Following Measles Infection Due to Vaccine Failure: A Case Report.

INTRODUCTION: Local outbreaks of measles infection are primarily mediated by international travel of persons from endemic areas, with subsequent spread of the virus via undervaccinated populations. Recent resurgences of measles in communities where vaccination rates are non-ideal secondary to philosophical objections require the emergency physician to more routinely consider the diagnosis. In cases of measles complicated by acute encephalitis or encephalopathy, the diagnosis can be especially difficult to make due to lack of a reliable primary historian. CASE REPORT: Here we present a case of altered mental status and new-onset bilateral lower extremity weakness in a fully vaccinated young woman diagnosed with measles infection caused by acute disseminated encephalomyelitis in the setting of vaccine failure. CONCLUSION: Despite a documented history of immunization, acute measles infection and its uncommon sequelae are possible. Recognizing vaccine failure and appropriately isolating patients are of paramount importance.

Machine Learning and Precision Medicine in Emergency Medicine: The Basics.

As machine learning (ML) and precision medicine become more readily available and used in practice, emergency physicians must understand the potential advantages and limitations of the technology. This narrative review focuses on the key components of machine learning, artificial intelligence, and precision medicine in emergency medicine (EM). Based on the content expertise, we identified articles from EM literature. The authors provided a narrative summary of each piece of literature. Next, the authors provided an introduction of the concepts of ML, artificial intelligence as an extension of ML, and precision medicine. This was followed by concrete examples of their applications in practice and research. Subsequently, we shared our thoughts on how to consume the existing research in these subjects and conduct high-quality research for academic emergency medicine. We foresee that the EM community will continue to adapt machine learning, artificial intelligence, and precision medicine in research and practice. We described several key components using our expertise.

Effectiveness and safety of fentanyl compared with morphine for out-of-hospital analgesia.

BACKGROUND: Fentanyl has several potential advantages for out-of-hospital analgesia, including rapid onset, short duration, and less histamine release. Objective. To compare the effectiveness and safety of fentanyl with that of morphine. METHODS: This was a retrospective before-and-after study of a protocol change from morphine to fentanyl in an advanced life support emergency medical services system in January 2007. Charts from nine months prior to the change and for nine months afterward were abstracted by two reviewers using a standardized instrument. The first three months after the change were excluded. Effectiveness was measured by change in pain scores on a 0-10 scale. A priori-defined adverse events included out-of-hospital events: respiratory rate <12 breaths/min, pulse oximetry <92%, systolic blood pressure <90 mmHg, any fall in Glasgow Coma Scale score, nausea or vomiting, intubation, and use of antiemetic agents or naloxone. Emergency department charts were reviewed for initial pain scores and the same adverse events during the first two hours. Events clearly not attributable to the opioid were discounted. The changes in pain scores were also compared adjusting for confounders by multivariable linear regression. RESULTS: Three hundred fifty-five patients aged 13 to 99 years received morphine during the nine months before the protocol change and 363 received fentanyl following the washout period. Initial pain scores for morphine (8.1) and fentanyl (8.3) were comparable (95% confidence interval [CI] for difference -1.1 to 0.3). Fentanyl patients received a higher equivalent dose of opioid (7.7 mg morphine equivalents for morphine, 9.2 mg for fentanyl, CI for the difference 0.9 to 2.3). The mean decreases in pain score were similar between the drugs (2.9 for morphine, 3.1 for fentanyl, CI for the difference -0.3 to 0.7). With regard to adverse events, 9.9% of the morphine patients and 6.6% of the fentanyl patients experienced an adverse event in the field (CI for the difference -0.8 to 7.3%). The most common event was nausea, with a rate of 7.0% for morphine vs. 3.8% for fentanyl (CI for the difference -0.1% to 6.5%). CONCLUSION: Morphine and fentanyl provide similar degrees of out-of-hospital analgesia, although this was achieved with a higher dose of fentanyl. Both medications had low rates of adverse events, which were easily controlled.

Injury hospitalization as a marker for emergency medical services use in elderly patients.

BACKGROUND: The elderly utilize emergency medical services (EMS) at a higher rate than younger patients, yet little is known about the influence of injury on subsequent EMS utilization and costs. OBJECTIVE: To assess injury hospitalization as a potential marker for subsequent EMS utilization and costs by Medicare patients. METHODS: This observational study analyzed a retrospective cohort of all Medicare patients (> or = 67 years old) with an International Classification of Diseases, Ninth Revision (ICD-9) injury diagnosis admitted to 125 Oregon and Washington hospitals during 2001 and 2002 who survived to hospital discharge. The numbers of EMS transports and the total EMS costs were compared one year before and one year following the index hospitalization. RESULTS: There were 30,655 injured elders in our cohort. Their median ICD-9-based injury severity score was 0.97, with 4.1% meeting a definition of serious injury and 37% having hip fractures. The mean (range) numbers of EMS transports before and after the injury were 0.5 (0-45) and 0.9 (0-56), for an unadjusted incidence rate ratio (IRR) of 1.7 (95% confidence interval [CI] 1.7-1.8). The increase in EMS utilization following an injury hospitalization was even greater after adjusting for risk period and other model predictors (IRR 2.4, 95% CI 2.3-2.5). Annual mean EMS costs rose 74% following the injury hospitalization, from $211 to $367 per person. The greatest increase was in nonemergent EMS use, accounting for 67% of the increase in the number of uses. Institutionalization in a skilled nursing or rehabilitation facility either before or after injury was strongly associated with the need for EMS care. CONCLUSION: An injury hospitalization in the elderly serves as a sentinel marker for an abrupt increase in EMS utilization and costs, even after accounting for confounders.

A randomized trial of a behavioral intervention to decrease hospital length of stay by decreasing bedrest.

BACKGROUND: Approximately half of hospitalized patients suffer functional decline due to spending the vast majority of their time in bed. Previous studies of early mobilization have demonstrated improvement in outcomes, but the interventions studied have been resource-intensive. We aimed to decrease the time hospital inpatients spend in bed through a pragmatic mobilization protocol. METHODS: This prospective, non-blinded, controlled clinical trial assigned inpatients to the study wards per routine clinical care in an urban teaching hospital. All subjects on intervention wards were provided with a behavioral intervention, consisting of educational handouts, by the nursing staff. Half of the intervention wards were supplied with recliner chairs in which subjects could sit. The primary outcome was hospital length of stay. The secondary outcome was the '6-Clicks' functional score. RESULTS: During a 6-month study period, 6082 patient encounters were included. The median length of stay was 84 hours (IQR 44-175 hours) in the control group, 80 hours (IQR 44-155 hours) in the group who received the behavioral intervention alone, and 88 hours (IQR 44-185 hours) in the group that received both the behavioral intervention and the recliner chair. In the multivariate analysis, neither the behavioral intervention nor the provision of a recliner chair was associated with a significant decrease in length of stay or increase in functional status as measured by the '6-Clicks' functional score. CONCLUSION: The program of educational handouts and provision of recliner chairs to discourage bed rest did not increase functional status or decrease length of stay for inpatients in a major urban academic center. Education and physical resources must be supplemented by other active interventions to reduce time spent in bed, functional decline, and length of stay.

Resident Clinical Experience in the Emergency Department: Patient Encounters by Postgraduate Year.

BACKGROUND: During emergency medicine (EM) training, residents are exposed to a wide spectrum of patient complaints. We sought to determine how resident clinical experience changes based on training level in relation to the patient acuity levels, chief complaints, and dispositions. METHODS: We performed a retrospective chart review of patients seen at a safety-net, academic hospital in Los Angeles from July 1, 2015, to June 30, 2016. Resident postgraduate year (PGY) level and specialty, patient acuity (based on the Emergency Severity Index), chief complaint (based on one of 30 categories), and disposition were abstracted. Our primary objective was to examine the progression of EM resident experience throughout the course of training. As a secondary objective, we compared the cases seen by EM and off-service PGY-1s. RESULTS: A total of 49,535 visits were examined, and of these, 32,870 (66.4%) were in the adult ED (AED) and 16,665 (33.6%) were in the pediatric ED (PED). The median acuity level was 3, and 27.4% of AED patients and 7.3% of PED patients were admitted. Data from 126 residents were analyzed. This included 94 PGY-1 residents (16 EM and 78 off-service), 16 PGY-2 EM, and 16 PGY-3 EM residents. Residents of different training levels evaluated different types of patients. Senior EM residents were more likely to care for higher-acuity patients than junior EM residents. EM PGY-3s saw higher percentages of acuity level 1 and 2 patients (2.3 and 37.8%, respectively, of their total patients) than EM PGY-1s (0.3 and 18.7%, respectively). Conversely, EM PGY-1s saw higher percentages of acuity level 4 and 5 patients (27.9 and 1.6%, respectively) compared to EM PGY-3s (10.7 and 0.7%, respectively). There was a significant linear trend for increasing acuity with training year among EM residents (p < 0.001). EM PGY-1s saw more patients than off-service PGY-1s with slightly higher acuities and admission rates. CONCLUSION: The clinical experience of EM residents varies based on their level of training. EM residents show a progression throughout residency and are more likely to encounter higher volumes of patients with higher acuity as they progress in their training. When designing EM residency curriculums, this is a model of an EM residency program.
