Emergency Department Buprenorphine and Naloxone Prescribing Disparities Among Racial and Ethnic Minorities Presenting With an Opioid Overdose.

The aim of the Research to Practice column is to enhance the research critique abilities of both advanced practice registered nurses and emergency nurses (RNs), while also aiding in the translation of research findings into clinical practice. Each column focuses on a specific topic and research study. In this article, we used two patient scenarios as a framework to delve into the 2023 secondary analysis of Papp and Emerman's study on "Disparities in Emergency Department Naloxone and Buprenorphine Initiation."

LGBTQIA+ Competence: A Pedagogical Paradigm Shift in Graduate Nursing Education.

BACKGROUND: The omission of lesbian, gay, bisexual, transgender, queer, intersex, asexual (LGBTQIA+) content in graduate nursing education leaves people who identify as sexually or gender diverse (SGD) with poorer health across the life span and a 12-year shorter life expectancy relative to heteronormative counterparts. METHOD: An educational intervention was paired with an optional academic-community-based clinical immersion in LGBTQIA+ health with the goal of improving health equity for people who identify as SGD. Masters of Nursing students (N = 11) from adult specialties participated in a two-credit elective in LGBTQIA+ health. Knowledge, skills, and attitudes (competency) preand postcourse completion were measured. RESULTS: Students showed a 62% improvement in competency results with 100% of students opting into the LGBTQIA+ clinical immersion. CONCLUSION: Teaching LGBTQIA+ health content is a requisite to advancing health equity for all, including people who identify as SGD. Until curricula become inclusive, clinical education should look for unique ways, such as clinical immersion, to ameliorate the shortfall. [J Nurs Educ. 2024;63(X):XXX-XXX.].

Analysis of Firework-Related Injuries to the Upper Extremity in the United States: 2011-2020.

INTRODUCTION: The purpose of this study is to examine and characterize patterns of injury to the upper extremity caused by fireworks in a nationally representative sample of emergency department patients from 2011 to 2020. METHODS: The National Electronic Injury Surveillance System was queried for upper-extremity injuries caused by fireworks between 2011 and 2020. RESULTS: One thousand two hundred fifty-one injuries were identified from the database representing 47,235 national cases that presented to emergency departments in the United States. Case frequency was stable during the period until 2020, which was nearly 70% higher than the previous 9-y average. Patients were generally young and male, with most cases in the 10-29-y age group and males over three times as likely to be injured as females. The most common injury was burn, and the week of July 4th accounted for 53% of cases alone. Diagnosis was also significantly associated with device type. CONCLUSIONS: These data can be used to target prevention measures and campaigns to specific patient populations most at risk of injury, specifically young males. They may also be used to highlight the impact of policy changes on availability of fireworks, the need for public health education coinciding with injury incidence peaks, and secondary pandemic effects.

Age of First Exposure to Contact Sports Is Not Associated With Worse Later-In-Life Brain Health in a Cohort of Community-Dwelling Older Men.

OBJECTIVE: To evaluate whether early age of first exposure to contact sports (AFE-CS) is associated with worse long-term brain health outcomes. DESIGN: A cross-sectional, survey study of older men with a history of contact sport participation was completed. SETTING: Tertiary care facility. PARTICIPANTS: A cohort of community-dwelling older men dichotomized by using AFE-CS (<12 years vs ≥12 years). INTERVENTIONS: Independent variables included a dichotomized group of AFE-CS (<12 years vs ≥12 years). MAIN OUTCOME MEASURES: Brain health outcomes measured by depression, anxiety, cognitive difficulties, and neurobehavioral symptoms. Endorsements of general health problems, motor symptoms, and psychiatric history were also collected. Age of first exposure groups was compared using t tests, χ2 tests, and multivariable linear regressions, which included the following covariates: age, number of prior concussions, and total years of contact sport. RESULTS: Of 69 men aged 70.5 ± 8.0 years, approximately one-third of the sample (34.8%) reported AFE-CS before age 12 years. That group had more years of contact sports (10.8 ± 9.2 years) compared with those with AFE-CS ≥12 (5.6 ± 4.5 years; P = 0.02). No differences were found after univariate testing between AFE-CS groups on all outcomes (P-values >0.05). Multivariable models suggest that AFE-CS is not a predictor of depression or anxiety. Those in the AFE-CS <12 group had fewer cognitive difficulties (P = 0.03) and fewer neurobehavioral symptoms (P = 0.03). CONCLUSIONS: Those with AFE-CS <12 to contact sports did not have worse long-term brain health outcomes compared with those with AFE-CS ≥12. Individuals with AFE-CS <12 had significantly lower British Columbia Cognitive Complaints Inventory and Neurobehavioral Symptom Inventory scores compared with those with AFE-CS ≥12. CLINICAL RELEVANCE: The benefits of earlier AFE-CS may outweigh the risks of head strikes and result in comparable long-term brain health outcomes.

Symptoms of Traumatic Encephalopathy Syndrome are Common in Community-Dwelling Adults.

BACKGROUND AND OBJECTIVES: The consensus criteria for traumatic encephalopathy syndrome (TES), the possible in vivo clinical syndrome associated with significant repetitive head impacts, have only been minimally studied to date. This study examined the prevalence of the proposed core clinical features of TES in a sample of healthy adults. METHODS: A cross-sectional survey study was conducted through ResearchMatch, a national health volunteer registry. Participants were assessed for symptoms of TES based on the 2021 consensus criteria, including prior repetitive head impacts and core clinical features. Additional health information (e.g., concussion history, psychological health, sleep, chronic pain) was also evaluated. The consensus proposed research criteria for TES (i.e., reporting at least one progressive core clinical feature of TES, as in progressive difficulties with episodic memory, executive functioning, or neurobehavioral dysregulation) were applied to the sample. RESULTS: Out of 1100 participants (average age = 53.6 ± 17.7 years, 55% women), 34.6% endorsed one or more progressive core clinical features of TES. Participants with a significant history of contact sports (i.e., ≥ 5 years total, with ≥ 2 years in high school or beyond) had similar rates of endorsing a progressive core clinical feature of TES compared to those without significant histories of repetitive head impacts (36.4% vs 32.8%, respectively, χ2 = 0.52, p = 0.47). A significant history of repetitive head impacts in sports was not associated with endorsing a core clinical feature of TES in univariable or multivariable models (p > 0.47), whereas current depression/anxiety (odds ratio [OR] = 6.94), a history of psychiatric disorders (OR = 2.57), current sleep problems (OR = 1.56), and younger age (OR = 0.99) were significant predictors of TES status in a multivariable model. In a subsample of 541 participants who denied a lifetime history of contact sports, other forms of repetitive head impacts, and concussions, approximately 31.0% endorsed one or more progressive core clinical features of TES. Additionally, 73.5% of neurotrauma-naïve participants with current anxiety or depression reported at least one core progressive feature of TES, compared with 20.2% of those without clinically significant depression/anxiety symptoms. CONCLUSIONS: A considerable proportion of adults without a significant history of repetitive head impacts from sports endorsed core TES features, particularly those experiencing mental health symptoms. Having a significant history of contact sports was not associated with endorsing a core progressive clinical feature of TES, whereas other health factors were. These findings underscore the need for validating and refining TES criteria in samples with and without substantial neurotrauma histories.

Symptom resolution following a repeat concussion within the same athlete.

INTRODUCTION: Repeat sport-related concussion (SRC) is anecdotally associated with prolonged recovery. Few studies have examined repeat concussion within the same athlete. We sought to explore differences in symptom burden and recovery outcomes in an individual athlete's initial and repeat SRC. METHODS: A retrospective within-subject cohort study of athletes aged 12-23 years diagnosed with two separate SRCs from 11/2017-10/2020 was conducted. Primary outcomes were initial symptom severity and time-to-symptom-resolution. Secondary outcomes included return-to-learn (RTL) and return-to-play (RTP) duration. RESULTS: Of 868 athletes seen, 47 athletes presented with repeat concussions. Median time between concussions was 244 days (IQR 136-395). Comparing initial to repeat concussion, no differences were observed in time-to-clinic (4.3 ± 7.3vs.3.7 ± 4.6 days, p = 0.56) or initial PCSS (26.2 ± 25.3 vs. 30.5 ± 24.1, p = 0.32). While a difference was observed in time-to-symptom resolution between initial/repeat concussion (21.2 ± 16.3 vs. 41.7 ± 86.0 days, p = 0.30), this did not reach statistical significance. No significant differences were observed in time-to-RTL (17.8 ± 60.6 vs. 6.0 ± 8.3 days, p = 0.26) and RTP (33.2 ± 44.1 vs. 29.4 ± 39.1 days, p = 0.75). Repeat concussion was not associated with symptom resolution on univariate (HR 1.64, 95% CI 0.96-2.78, p = 0.07) and multivariable (HR 0.85, 95% CI 0.49-1.46, p = 0.55) Cox regression. CONCLUSION: No significant differences in symptom duration and RTP/RTL were seen between initial/repeat concussion.

An Evidence-Based Algorithm of Management of Heatstroke in the Emergency Department.

Annual rates of heat illness and heat-related deaths have been increasing across the United States as more regions of the country have been experiencing heat waves of extreme ambient temperatures of prolonged durations. According to the Centers for Disease Control and Prevention, heat illnesses have become the leading cause of weather-related deaths. This article critiques and describes the findings of a systematic review by C. Rublee et al. (2021). The review was conducted to develop an evidence-based algorithm specific for management of heatstroke in the emergency department with implications for improving recognition, initiating rapid cooling, and providing supportive care to reduce patient mortality and morbidity.

Examining the New Consensus Criteria for Traumatic Encephalopathy Syndrome in Community-Dwelling Older Adults.

In 2021, an expert panel of clinician-scientists published the first consensus research diagnostic criteria for traumatic encephalopathy syndrome (TES), a clinical condition thought to be associated with chronic traumatic encephalopathy neuropathological change. This study evaluated the TES criteria in older adults and assessed associations between TES criteria and a history of repetitive head impacts. This cross-sectional, survey-based study examined the symptoms of TES, previous repetitive head impacts, and a variety of current health difficulties. To meet symptom criteria for TES, participants had to report progressive changes with memory, executive functioning, and/or neurobehavioral dysregulation. To meet the criterion for substantial exposure to repetitive head impacts via contact sports, participants reported at least 5 years of contact sport exposure (with 2+ years in high school or beyond). A sample of 507 older adults (mean age = 70.0 years, 65% women) completed the survey and 26.2% endorsed having one or more of the progressive core clinical features of TES. Those who had a significant history of contact sport exposure were not significantly more likely to meet TES criteria compared with those who did not (31.3% vs. 25.3%, p = 0.46). In a binary logistic regression predicting TES status, current depression or anxiety (odds ratio [OR] = 12.55; 95% confidence interval [CI] = 4.43-35.51), history of psychiatric disorders (OR = 2.07, 95% CI = 1.22-3.49), male sex (OR = 1.87), and sleep problems (OR = 1.71, 95% CI = 1.01-2.91) were associated with meeting TES criteria. The sport exposure criterion, age, and current pain were not significantly associated with TES status (ps > 0.05). A significant minority of participants with no history of neurotrauma endorsed symptoms consistent with TES (22.0% of men and 19.8% of women). Nearly 80% of neurotrauma naïve participants with clinically significant anxiety/depression met criteria for TES. In summary, approximately one in four older adults met the symptom criteria for TES, many of whom had no history of repetitive neurotrauma. Mental health problems and sleep issues were associated with TES, whereas having a history of repetitive head impacts in contact sports was not. These data suggest that the new consensus diagnostic criteria for TES may have low specificity and may carry a higher risk of misdiagnosing those with other physical and mental health conditions as having TES.

Ethnicity Is Associated With Differing Presentation and Outcomes of Patients Undergoing Aortic Valve Replacement for Calcific Aortic Stenosis in Aotearoa New Zealand.

AIM: Surgical aortic valve replacement (SAVR) has been the gold standard for treatment of severe symptomatic aortic stenosis (AS) for decades. We examined whether ethnic differences exist in the presentation and outcomes of patients undergoing aortic valve replacement (AVR) for AS in New Zealand. METHODS: Patients of New Zealand European, Maori, and Pacific Island ethnicities undergoing SAVR with or without other procedures in New Zealand public hospitals from 2017 to 2019 were included. Major postoperative outcomes were compared between ethnic groups, with 30-day mortality being the primary outcome. RESULTS: A total of 1,175 patients were included: 1,085 European, 50 Maori, and 40 Pacific. The mean age was 71.1±9.4 years, and men accounted for more than half of all patients (69.9%). Maori (64.7±9.4 years) and Pacific (65.4±10.1 years) patients were younger when undergoing SAVR compared with European patients (71.7±9.2; analysis of variance p<0.001). Maori and Pacific patients had a higher prevalence of diabetes, poorer renal function, and worse left ventricular function; 30-day mortality was higher in Maori and Pacific compared with European patients (6% and 10% vs 2.4%, respectively; Fisher's exact test p=0.011), with odds ratio of 3.06 (95% confidence interval [CI] 0.88-10.66) for Maori patients after adjustment for EuroSCORE II and odds ratio of 5.23 (95% CI 1.79-16.07) for Pacific patients. CONCLUSIONS: There are significant differences in presentation and outcomes of patients undergoing AVR in New Zealand. Maori and Pacific patients undergo SAVR at a younger age, have more preoperative comorbidities, and have higher rates of 30-day mortality than European patients.

Neurological Examination Frequency and Time-to-Delirium After Traumatic Brain Injury.

BACKGROUND: Frequent neurological examinations in patients with traumatic brain injury (TBI) disrupt sleep-wake cycles and potentially contribute to the development of delirium. OBJECTIVE: To evaluate the risk of delirium among patients with TBI with respect to their neuro-check frequencies. METHODS: A retrospective study of patients presenting with TBI at a single level I trauma center between January 2018 and December 2019. The primary exposure was the frequency of neurological examinations (neuro-checks) assigned at the time of admission. Patients admitted with hourly (Q1) neuro-check frequencies were compared with those who received examinations every 2 (Q2) or 4 (Q4) hours. The primary outcomes were delirium and time-to-delirium. The onset of delirium was defined as the first documented positive Confusion Assessment Method for the Intensive Care Unit score. RESULTS: Of 1552 patients with TBI, 458 (29.5%) patients experienced delirium during their hospital stay. The median time-to-delirium was 1.8 days (IQR: 1.1, 2.9). Kaplan-Meier analysis demonstrated that patients assigned Q1 neuro-checks had the greatest rate of delirium compared with the patients with Q2 and Q4 neuro-checks ( P < .001). Multivariable Cox regression modeling demonstrated that Q2 neuro-checks (hazard ratio: 0.439, 95% CI: 0.33-0.58) and Q4 neuro-checks (hazard ratio: 0.48, 95% CI: 0.34-0.68) were protective against the development of delirium compared with Q1. Other risk factors for developing delirium included pre-existing dementia, tobacco use, lower Glasgow Coma Scale score, higher injury severity score, and certain hemorrhage patterns. CONCLUSION: Patients with more frequent neuro-checks had a higher risk of developing delirium compared with those with less frequent neuro-checks.

Exploring the different cognitive, emotional and imaginative experiences of autistic and non-autistic adult readers when contemplating serious literature as compared to non-fiction.

Introduction: Recent research has demonstrated how reflections on serious literature can challenge dominant social-deficit views of autism. This method enables autistic readers to explore social realities more slowly and carefully, encouraging detail-focused considerations. Previous research has also shown that autistic and non-autistic readers reflecting on serious literature together are able to achieve mutuality in a way that enables them to overcome the double empathy problem. However, the advantages of reading aloud designs have yet to be explored with autistic and non-autistic readers due to previous concerns amongst autistic people on the issue of being read aloud to. The present study aimed to explore how an adapted shared reading design that compared serious literature and non-fiction would enable autistic and non-autistic readers to imaginatively engage in the reading experience. Methods: Seven autistic and six non-autistic participants read 8 short text extracts alone while listening to pre-recorded audio of an experienced reader reading each text aloud. Participants completed a reflective questionnaire for each text and a follow-up interview where moving parts of the text were then re-read aloud before discussion. Half of these texts were serious literature, while the other half were non-fiction. Similarly, half of the texts explored fictional social realities that depicted a lack of mutuality, or non-fiction accounts of autism; while the other half explored broader emotional experiences. Results: Thematic and literary analysis of participant reflections and follow-up interviews revealed three main themes: (1) From Surface Reading to Intuitive Engagement, (2) Imaginative Feeling and (3) Going Forward from the Reading Experience. Discussion: The findings showed that autistic readers were better able to hold onto the detailed complexity of serious literature, while non-autistic readers tended to reduce information down to key ideas and understandings for later generalization. Findings are discussed in relation to future shared reading designs.

Combination of precipitation and size exclusion chromatography as an effective method for exosome like extracellular vesicle isolation from pericardial fluids.

Extracellular vesicles (EVs), such as exosomes, are nanovesicles that have received significant attention due to their ability to contain various molecular cargos. EVs found in biological fluids have been demonstrated to have therapeutic potential, including as biomarkers. Despite being extensively studied, a significant downfall in EV research is the lack of standardised protocol for its isolation from human biological fluids, where EVs usually exist at low densities. In this study, we tested two well-established EV isolation protocols, precipitation, and size exclusion chromatography (SEC), to determine their efficiency in isolating EVs from the pericardial fluid. Precipitation alone resulted in high yields of low-purity exosomes as tested by DLS analysis, transmission electron microscopy, immunogold labelling and western blotting for the exosomal surface proteins. While EVs isolated by SEC were pure, the concentration was low. Interestingly, the combination of precipitation followed by SEC resulted in high EV yields with good purity. Our results suggest that the combination method can be adapted to isolate EVs from body fluids which have low densities of EV.

Development of practice recommendations based on the Canadian Syncope Risk Score and identification of barriers and facilitators for implementation.

BACKGROUND: Wide variations in emergency department (ED) syncope management exist. The Canadian Syncope Risk Score (CSRS) was developed to predict the probability of 30-day serious outcomes after ED disposition. Study objectives were to evaluate the acceptability of proposed CSRS practice recommendations among providers and patients, and identify barriers and facilitators for CSRS use to guide disposition decisions. METHODS: We conducted semi-structured interviews with 41 physicians involved in ED syncope and 35 ED patients with syncope. We used purposive sampling to ensure a variety of physician specialties and CSRS patient risk levels. Thematic analysis was completed by two independent coders with consensus meetings to resolve conflicts. Analysis proceeded in parallel with interviews until data saturation. RESULTS: The majority (97.6%; 40/41) of physicians agreed with discharge of low risk (CSRS ≤ 0) but opined that 'no follow up' changed to 'follow-up as needed'. Physicians indicated current practices do not align with the medium-risk recommendation to discharge patients with 15-day monitoring (CSRS = 1-3; due to lack of access to monitors and timely follow-up) and the high-risk recommendation (CSRS ≥ 4) to potentially discharge patients with 15-day monitoring. Physicians recommended brief hospitalization of high-risk patients due to patient safety concerns. Facilitators included the CSRS-based patient education and scores supporting their clinical gestalt. Patients reported receiving varying levels of information regarding syncope and post-ED care, were satisfied with care received and preferred less resource intensive options. CONCLUSION: Our recommendations based on the study results were: discharge of low-risk patients with physician follow-up as needed; discharge of medium-risk patients with 15-day cardiac monitoring and brief hospitalization of high-risk patients with 15-day cardiac monitoring if discharged. Patients preferred less resource intensive options, in line with CSRS recommended care. Implementation should leverage identified facilitators (e.g., patient education) and address the barriers (e.g., monitor access) to improve ED syncope care.

RéSUMé: CONTEXTE: La prise en charge des syncopes par les services d'urgence varie considérablement. Le Canadian Syncope Risk Score (CSRS) a été mis au point pour prédire la probabilité d'une issue grave à 30 jours après la prise en charge par le service des urgences. Les objectifs de l'étude étaient d'évaluer l'acceptabilité des recommandations pratiques proposées par le CSRS parmi les prestataires et les patients, et d'identifier les barrières et les facilitateurs de l'utilisation du CSRS pour guider les décisions de disposition. MéTHODES: Nous avons mené des entretiens semi-structurés avec 41 médecins impliqués dans la syncope aux urgences et 35 patients souffrant de syncope aux urgences. Nous avons utilisé un échantillonnage raisonné pour assurer une variété de spécialités médicales et de niveaux de risque pour les patients du CSRS. L'analyse thématique a été réalisée par deux codeurs indépendants, avec des réunions de consensus pour résoudre les conflits. L'analyse s'est déroulée parallèlement aux entretiens jusqu'à saturation des données. RéSULTATS: La majorité (97,6 % ; 40/41) des médecins étaient d'accord avec la sortie des patients à faible risque (CSRS ≤ 0), mais ont estimé que " pas de suivi " devait être remplacée par " suivi en fonction des besoins ". Les médecins ont indiqué que leurs pratiques actuelles ne sont pas conformes à la recommandation à risque moyen de faire sortir les patients avec une surveillance de 15 jours (CSRS = 1-3 ; en raison du manque d'accès aux moniteurs et au suivi en temps opportun) et à la recommandation à risque élevé (CSRS ≥ 4) de potentiellement faire sortir les patients avec une surveillance de 15 jours. Les médecins ont recommandé une brève hospitalisation des patients à haut risque pour des raisons de sécurité. Les facilitateurs comprenaient l'éducation des patients basée sur le CSRS et les scores soutenant leur gestalt clinique. Les patients ont déclaré avoir reçu différents niveaux d'information concernant la syncope et les soins post-urgence, étaient satisfaits des soins reçus et préféraient des options moins gourmandes en ressources. CONCLUSIONS: Nos recommandations basées sur les résultats de l'étude sont les suivantes : sortie des patients à faible risque avec suivi par un médecin si nécessaire ; la sortie des patients à risque moyen avec une surveillance cardiaque de 15 jours et une brève hospitalisation des patients à risque élevé avec une surveillance cardiaque de 15 jours en cas de sortie. Les patients ont préféré des options moins gourmandes en ressources, conformément aux soins recommandés par le CSRS. La mise en œuvre devrait s'appuyer sur les facilitateurs identifiés (par exemple, l'éducation des patients) et s'attaquer aux obstacles (par exemple, le contrôle de l'accès) pour améliorer les soins aux urgences en cas de syncope.

'Looking before and after': Can simple eye tracking patterns distinguish poetic from prosaic texts?

Introduction: The study of 'serious' literature has recently developed into an emerging field called neurocognitive poetics that applies cognitive neuroscientific techniques to examine how we understand and appreciate poetry. The current research used eye-tracking techniques on a small sample of young adults to see if and how the reading of short pieces of poetry differed from the reading of matched prosaic texts. Methods: With 'proof of concept' intentions reflecting arguments first proposed by 19th Century literary figures, there was a particular focus on the differences between the reading of poetry and prose in terms number and frequency of fixations and regressive eye movements back and forth within the texts in this two-by-two experimental design (poetry vs. prose x need vs. no need for final line reappraisal). Results: It was found that poetic pieces compared to prosaic pieces were associated with more and longer fixations and more regressive eye movements throughout the text. The need to reappraise meaning at the prompt of a final line was only significantly associated with more regressive eye movements. Comparisons examining the 4 text conditions (poetic reappraisal, poetic non-reappraisal, prosaic reappraisal, and prosaic non-reappraisal) showed that the poetic reappraisal condition was characterised by significantly more regressive eye movements as well as longer fixations compared to the prosaic non-reappraisal condition. No significant correlations were found between self-reported literary familiarity and eye tracking patterns. Discussion: Despite limitations, this proof-of-concept study provides insights into reading patterns that can help to define objectively the nature of poetic material as requiring slower reading particularly characterised by more and longer fixations and eye movements backwards through the texts compared to the faster, more linear reading of prose. Future research using these, and other psychophysiological metrics can begin to unpack the putative cognitive benefits of reading literary material.

Reducing Adult Transgender Barriers to Care in the Emergency Department: Strategies to Improve Policies and Practices.

The Research to Practice column is intended to improve the research critique skills of the advanced practice registered nurse (APRN) and the emergency department (ED) registered nurse (RN) and to assist with translating research into practice. In this column, we review a recent qualitative research study by M. Allison, S. Marshall, G. Stewart, M. Joiner, C. Nash, and M. Stewart (2021) titled "Experiences of Transgender and Gender Nonbinary Patients in the Emergency Department and Recommendations for Health Care Policy, Education, and Practice" with discussion of how their findings can be applied to inform providers how to deliver appropriate care of transgender patients within the ED.

Assessment of safety and effectiveness of non-neurosurgical management for minimal traumatic brain injury (TBI).

BACKGROUND: Patients with mild traumatic brain injury (TBI) and intracranial hemorrhage often receive neurosurgical consultation. However, only a small proportion of patients require intervention. Our hypothesis is that low-risk minimal TBI patients managed without immediate neurosurgical consultation will have a reasonable safety and effectiveness outcome profile. METHODS: A non-neurosurgical management protocol for adult minimal TBI was implemented at a level I trauma center as an interdisciplinary quality-improvement initiative in November 2018. Minimal TBI was defined as Glasgow Coma Scale (GCS) of 15 secondary to blunt mechanism, without anticoagulant or antiplatelet therapy, and isolated pneumocephalus and/or traumatic subarachnoid hemorrhage on head CT imaging. Safety was assessed by in-hospital mortality, neurosurgical interventions, and ED revisits within two weeks of discharge. Effectiveness was assessed by neurosurgical consult rate and length of stay. Outcomes were compared 8-months pre- and post-protocol implementation. RESULTS: A total of 97 patients were included, of which 49 were pre-protocol and 48 were post-protocol There was no difference in rates of in-hospital mortality [0 (0%) vs 0 (0%)], neurosurgical procedure [1 (2.1%) vs 0 (0%)], operations [0 (0%) vs 0 (0%)], and ED revisits [1 (2.0%) vs 2 (4.2%), p = 0.985] between the periods. There was a significant reduction in neurosurgical consults post-protocol implementation (92% vs 29%, p<0.001). CONCLUSION: A protocol for minimal TBI patients effectively reduced neurosurgical consultation without changes in safety profile. Such an interdisciplinary management protocol for low-risk neurotrauma can effectively utilize the neurosurgery consult services by stratifying neurologically stable TBI patient.

Dysuria, Rebound Tenderness, and a Palpable Mass-A Ticking Time Bomb.

A 37-year-old male presented to the emergency department with the complaint of periumbilical abdominal pain, radiating to just above pubic symphysis. The patient reported that the pain was worse with urination and associated with chills and nausea. This case reports discusses the Emergency Department (ED) course and subsequent treatment of a patient found to have an infected urachal cyst, a previously asymptomatic embryological anomaly in an otherwise healthy middle-aged adult male. This is a crucial diagnosis to make in order to avoid the potential for significant morbidity and/or mortality, given the unlikely symptomatic source.

Traumatic chest wall pyomyositis presenting with mediastinitis.

Pyomyositis is an acute bacterial infection of the skeletal muscle that is commonly associated with localized abscess formation. It is estimated that pyomyositis accounts for up to 4% of all hospital admissions throughout Asia, tropical Africa, Oceania and the Caribbean Islands. However, there has been an increasing emergence of pyomyositis in temperate climates and high-income countries. Staphylococcus aureus is the most common organism implicated. Management requires a high index of clinical suspicion, prompt diagnosis and early management to prevent sequalae that can be fatal if left untreated. We describe an interesting case of pyomyositis in an otherwise fit and immunocompetent individual causing mediastinitis; a rare sequalae of the disease. Percutaneous drainage of his left pectoral abscess and a prolonged course of antibiotics provided complete clinical and radiological resolution of the disease despite mediastinal extension. Here we discuss aetiology, associations, pathophysiology and epidemiology of pyomyositis with associated sequalae of the disease.

Diagnostic yield of screening for SARS-CoV-2 among patients admitted to hospital for alternate diagnoses: an observational cohort study.

OBJECTIVES: To determine the diagnostic yield of screening patients for SARS-CoV-2 who were admitted with a diagnosis unrelated to COVID-19 and to identify risk factors for positive tests. DESIGN: Cohort from the Canadian COVID-19 Emergency Department Rapid Response Network registry. SETTING: 30 acute care hospitals across Canada. PARTICIPANTS: Patients hospitalised for non-COVID-19-related diagnoses who were tested for SARS-CoV-2 between 1 March and 29 December 2020. MAIN OUTCOME: Positive nucleic acid amplification test for SARS-CoV-2. OUTCOME MEASURE: Diagnostic yield. RESULTS: We enrolled 15 690 consecutive eligible adults who were admitted to hospital without clinically suspected COVID-19. Among these patients, 122 tested positive for COVID-19, resulting in a diagnostic yield of 0.8% (95% CI 0.64% to 0.92%). Factors associated with a positive test included presence of fever, being a healthcare worker, having a positive household contact or institutional exposure, and living in an area with higher 7-day average incident COVID-19 cases. CONCLUSIONS: Universal screening of hospitalised patients for COVID-19 across two pandemic waves had a low diagnostic yield and should be informed by individual-level risk assessment in addition to regional COVID-19 prevalence. TRIAL REGISTRATION NUMBER: NCT04702945.
