Epidemiology and Prevalence of Dyslipidemia Among Adult Population of Tehran: The Tehran Cohort Study.

BACKGROUND: Dyslipidemia is among the leading risk factors for cardiovascular diseases (CVDs), with an increasing global burden, especially in developing countries. We investigated the prevalence of dyslipidemia and abnormal lipid profiles in Tehran. METHODS: We used data from 8072 individuals aged≥35 from the Tehran Cohort Study (TeCS) recruitment phase. Fasting serum total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), and triglyceride were measured. Dyslipidemia was defined according to the National Cholesterol Education Program Adult Treatment Panel III criteria, and high LDL/HDL was defined as a ratio>2.5. The age-sex standardized prevalence rates were calculated based on the 2016 national census. Furthermore, the geographical distribution of dyslipidemia and lipid abnormalities was investigated across Tehran's zip code districts. RESULTS: The age-sex standardized prevalence was 82.7% (95% CI: 80.1%, 85.0%) for dyslipidemia, 36.9% (95% CI: 33.8%, 40.1%) for hypertriglyceridemia, 22.5% (95% CI: 19.9%, 25.4%) for hypercholesterolemia, 29.0% (95% CI: 26.1%, 32.1%) for high LDL-C, 55.9% (95% CI: 52.6%, 59.2%) for low HDL-C, and 54.1% (95% CI: 50.9%, 57.3%) for high LDL/HDL ratio in the Tehran adult population. The prevalence of dyslipidemia, low HDL-C, and high LDL/HDL ratio was higher in the northern regions, hypercholesterolemia was higher in the southern half, and high LDL-C was more prevalent in the middle-northern and southern areas of Tehran. CONCLUSION: We found a high prevalence of dyslipidemia, mainly high LDL/HDL in the Tehran adult population. This dyslipidemia profiling provides important information for public health policy to improve preventive interventions and reduce dyslipidemiarelated morbidity and mortality in the future.

Erector spinae plane block (ESPB) for intractable, non-surgical abdominal pain: a scoping review.

Abdominal pain is one of the most common presenting chief complaints in the emergency department (ED). Erector spinae plane block (ESPB) is an ultrasound-guided nerve block with proven effectiveness in treating visceral and somatic abdominal pain. Despite the increasing popularity of ESPB, its role in the management of non-surgical abdominal pain has not yet been characterized. Our scoping review aims to review the current literature on the safety and efficacy of ESPB in the management of patients experiencing intractable, non-surgical abdominal pain. We searched PubMed and Scopus to evaluate the existing literature on ESPB for non-surgical abdominal pain. Reviewers screened 30 titles and abstracts that met the predefined inclusion and exclusion criteria. Following initial screening, 24 articles underwent full-text review. Two reviewers also screened references included in each study. A total of 14 journal articles were reviewed, including 12 case-based studies, one systematic review, and one narrative review of ESPB in the treatment of non-surgical abdominal pain. All cases described the successful use of ESPB in treating abdominal pain refractory to oral or intravenous analgesic medications, and each case reported no complications. This scoping review provides support for ESPB in the management of intractable, non-surgical abdominal pain. ESPB demonstrates efficacy in alleviating various conditions such as functional abdominal pain, renal colic, pancreatitis, herpetic pain, and cancer-related pain. Theoretical risks such as pneumothorax, bleeding, and infection are possible, although the studies reviewed did not report such complications.

Assessing the Efficacy of a Novel Massive Open Online Soft Skills Course for South Asian Healthcare Professionals.

In healthcare professions, soft skills contribute to critical thinking, decision-making, and patient-centered care. While important to the delivery of high-quality medical care, soft skills are often underemphasized during healthcare training in low-and-middle-income countries. Despite South Asia's large population, the efficacy and viability of a digital soft skills curriculum for South Asian healthcare practitioners has not been studied to date. We hypothesized that a web-based, multilingual, soft skills course could aid the understanding and application of soft skills to improve healthcare practitioner knowledge, confidence, attitudes, and intent-to-change clinical practice.In September 2019 a needs assessment observing soft skills practices was conducted in several Indian states. We developed a communication-focused soft skills curriculum that comprised seven 10-minute video lectures, recorded in spoken English and Hindi. Participants consisted of any practicing healthcare professionals and trainees in select South Asian countries age 18 and over. Participant knowledge, confidence, attitudes, and intent-to-change clinical practice were evaluated using pre- and post-course tests and surveys. Statistical analyses were performed using STATA and SPSS.From July 26, 2021 to September 26, 2021, 5750 registered and attempted the course, 2628 unique participants completed the pre-test, and 1566 unique participants completed the post-test. Participants demonstrated small but statistically significant gains in confidence (𝑝<0.001), attitudes toward course topics relevance (𝑝<0.001), and intent-to-change clinical practice (𝑝<0.001). There was no statistically significant gain in knowledge. A digital soft-skills massive open online course for healthcare practitioners in South Asia could serve as a viable approach to improve the quality of soft skills training in low-to-middle income countries.

Epidemiology of substance and opium use among adult residents of Tehran; a comprehensive report from Tehran cohort study (TeCS).

BACKGROUND: The prevalence and burden of substance and opium use have increased worldwide over the past decades. In light of rapid population changes in Tehran, we aimed to evaluate the prevalence of opium and other substance use among adult residents in Tehran, Iran. METHOD: From March 2016 to March 2019, we utilized data from 8 296 participants in the Tehran Cohort Study recruitment phase (TeCS). We calculated the age-sex-weighted prevalence of substance use and the geographic distribution of substance use in Tehran. We also used logistic regression analysis to determine possible determinants of opium use. RESULT: We analyzed data from 8 259 eligible participants with complete substance use data and the average age of participants was 53.7 ± 12.75 years. The prevalence of substance use was 5.6% (95% confidence interval [CI]: 4.6- 7.1%). Substance use was more common in males than females (Prevalence: 10.5% [95% CI: 8.6- 12.6%] vs. 0.5% [95% CI: 0.2- 1.2%], respectively). The age-sex weighted prevalence of substance use was 5.4% (95% CI: 4.6-7.1%). Moreover, opium was the most frequently used substance by 95.8% of substance users. Additionally, we found that male gender (Odds ratio [OR]: 12.1, P < 0.001), alcohol intake (OR: 1.3, P = 0.016), and smoking (OR: 8.5, P < 0.001) were independently associated with opium use. CONCLUSIONS: We found that the prevalence of substance use in Tehran was 5.6%, and opium was the most frequently used substance. In addition, male gender, lower levels of education, alcohol, and tobacco consumption are the main risk factors for substance use in Tehran. Healthcare providers and policymakers can utilize our results to implement preventive strategies to minimize substance use in Tehran.

Why is naloxone prescription not more common in emergency departments? A survey of physician practices and attitudes.

OBJECTIVE: Emergency physicians (EPs) have a singular opportunity to prescribe naloxone and decrease fatal overdoses in opioid users. We surveyed EPs patterns of naloxone prescription and identified barriers to prescribing naloxone. DESIGN: Surveys were conducted at an emergency medicine conference from 2018 to 2019. We used a Likert scale for all questions and a chi-square or chi-square for trend tests to determine statistical significance. SETTING: Emergency medicine conferences and emergency departments. PARTICIPANTS: Forty-one EPs were surveyed. INTERVENTION: Oral survey. MAIN OUTCOME MEASURES: Prevalence of naloxone prescription and EP attitude toward naloxone. RESULTS: 65.0 percent of residents and 33.3 percent of attending physicians had never prescribed naloxone to patients. 90.2 percent believed ED naloxone prescription is safe, 82.9 percent did not refrain from prescribing due to ethical concerns, and 73.2 percent believed it is not a waste of resources. CONCLUSIONS: Many resident physicians had never prescribed naloxone despite agreeing it was safe, ethical, and a productive use of resources. The time needed to counsel patients on naloxone use was a barrier to prescription, and various interventions are needed to make this practice more common.

Using a Linear Probe Ultrasound for the Detection of First-Trimester Pregnancies in the Emergency Department.

Linear probe point-of-care ultrasound (LPUS) presents a less invasive alternative for identifying intrauterine pregnancies (IUPs) compared to usual practice (transabdominal (TAUS) or transvaginal (TVUS) ultrasound). TAUS and TVUS can be invasive or produce lower-resolution images than LPUS. The purpose of this study is to determine whether a linear probe alone can identify first-trimester IUPs. A convenience sample of 21 patients were enrolled at the University of California Irvine ED during a 7-month period. The inclusion criteria were English- or Spanish-speaking women (≥18 years) in their first trimester of pregnancy (≤12 weeks pregnant) with a body mass index (BMI) of <35. The exclusion criteria were psychiatric, incarcerated, or cognitively impaired patients. An ED physician performed LPUS and ordered a confirmatory ultrasound. The 21 patients enrolled had a mean age of 28.6 ± 6.60 years, BMI of 26.6 ± 5.03, and gestational age of 7.4 ± 2.69 weeks. Considering the 95% confidence interval, we are 97.5% confident that the sensitivity and specificity of LPUS to identify IUPs does not exceed 67.1% and 93.2%, respectively. Our pilot data did not demonstrate that LPUS can independently visualize IUPs in first-trimester patients.

Utilization and Impact of Pharmacist-led, Urinary Culture Follow-Up After Discharge from the Emergency Department.

INTRODUCTION: Urinary tract infections (UTI) are a common reason for an emergency department (ED) visit. The majority of these patients are discharged directly home without a hospital admission. After discharge, emergency physicians have traditionally managed the care of the patient if a change is warranted (as a result of urine culture results). However, in recent years clinical pharmacists in the ED have largely incorporated this task into their standard practice. In our study, we aimed to 1) describe our unique process in having a pharmacist-led, urinary culture follow-up, and 2) compare it to our previous, more traditional process. METHODS: In our retrospective study, we evaluated the impact of a pharmacist-led, urinary culture follow-up program after discharge from the ED. We included patients prior to and after the implementation of our new protocol to compare the differences. The primary outcome was time to intervention after urine culture result was released. Secondary outcomes included rate of documentation of intervention, appropriate interventions made, and repeat ED visits within 30 days. RESULTS: We included a total of 265 unique urine cultures from 264 patients in the study: 129 cultures were from the period prior to implementation of the protocol, and 136 were from the post-implementation period. There were no significant differences between pre- and post-implementation groups for the primary outcome. Appropriate therapeutic intervention based on positive urine culture results was 16.3% in the pre-implementation group vs 14.7% in the post-implementation group (P=0.72). Secondary outcomes of time to intervention, documentation rates, and readmissions were similar between both groups. CONCLUSION: Implementation of a pharmacist-led, urinary culture follow-up program after discharge from the ED led to similar outcomes as a physician-run program. An ED pharmacist can successfully run a urinary culture follow-up program in an ED without physician involvement.

Nonfatal Injuries Sustained in Mass Shootings in the US, 2012-2019: Injury Diagnosis Matrix, Incident Context, and Public Health Considerations.

INTRODUCTION: The epidemic of gun violence in the United States (US) is exacerbated by frequent mass shootings. In 2021, there were 698 mass shootings in the US, resulting in 705 deaths and 2,830 injuries. This is a companion paper to a publication in JAMA Network Open, in which the nonfatal outcomes of victims of mass shootings have been only partially described. METHODS: We gathered clinical and logistic information from 31 hospitals in the US about 403 survivors of 13 mass shootings, each event involving greater than 10 injuries, from 2012-19. Local champions in emergency medicine and trauma surgery provided clinical data from electronic health records within 24 hours of a mass shooting. We organized descriptive statistics of individual-level diagnoses recorded in medical records using International Classification of Diseases codes, according to the Barell Injury Diagnosis Matrix (BIDM), a standardized tool that classifies 12 types of injuries within 36 body regions. RESULTS: Of the 403 patients who were evaluated at a hospital, 364 sustained physical injuries-252 by gunshot wound (GSW) and 112 by non-ballistic trauma-and 39 were uninjured. Fifty patients had 75 psychiatric diagnoses. Nearly 10% of victims came to the hospital for symptoms triggered by, but not directly related to, the shooting, or for exacerbations of underlying conditions. There were 362 gunshot wounds recorded in the Barell Matrix (1.44 per patient). The Emergency Severity Index (ESI) distribution was skewed toward higher acuity than typical for an emergency department (ED), with 15.1% ESI 1 and 17.6% ESI 2 patients. Semi-automatic firearms were used in 100% of these civilian public mass shootings, with 50 total weapons for 13 shootings (Route 91 Harvest Festival, Las Vegas. 24). Assailant motivations were reported to be associated with hate crimes in 23.1%. CONCLUSION: Survivors of mass shootings have substantial morbidity and characteristic injury distribution, but 37% of victims had no GSW. Law enforcement, emergency medical systems, and hospital and ED disaster planners can use this information for injury mitigation and public policy planning. The BIDM is useful to organize data regarding gun violence injuries. We call for additional research funding to prevent and mitigate interpersonal firearm injuries, and for the National Violent Death Reporting System to expand tracking of injuries, their sequelae, complications, and societal costs.

Optimal Image Gain Intensity of Point-of-care Ultrasound when Screening for Ocular Abnormalities in the Emergency Department.

INTRODUCTION: Point-of-care ultrasound (POCUS) plays a pivotal role in evaluating ocular complaints in the emergency department (ED). The rapid and non-invasive nature of ocular POCUS makes it a safe and informative imaging modality. Previous studies have investigated using ocular POCUS to diagnose posterior vitreous detachment (PVD), vitreous hemorrhage (VH), and retinal detachment (RD); however, there are few studies that assess image optimization techniques and how they impact the overall accuracy of ocular POCUS. METHODS: We performed a retrospective review of ED patients who received ocular POCUS examinations and ophthalmology consultations as part of their evaluation for eye complaints at our urban, Level I trauma center ED from November 2017-January 2021. Of 706 exams, 383 qualified for the study. In this study we primarily investigated how stratified gain levels impact the accuracy of ocular POCUS for detection of any posterior chamber pathology and, secondarily, whether stratified gain levels impact the accuracy of detecting RD, VH, and PVD specifically. RESULTS: The images were found to have an overall sensitivity of 81% (76-86%), specificity of 82% (76-88%), positive predictive value (PPV) of 86% (81-91%), and negative predictive value (NPV) of 77% (70-83%). Images acquired with a gain of (25, 50] had a sensitivity of 71% (61-80%), specificity of 95% (85-99%), PPV of 96% (88-99%), and NPV of 68% (56-78%). Images acquired with a gain of (50, 75] had a sensitivity of 85% (73-93%), specificity of 85% (72-93%), PPV of 86% (75-94%), and NPV of 83% (70-92%). Images acquired with a high gain (75, 100] had a sensitivity of 91% (82-97%), specificity of 67% (53-79%), PPV of 78% (68-86%), and NPV of 86% (72-95%). CONCLUSION: In the ED setting, high (75, 100] gain on ocular POCUS scanning has a higher degree of sensitivity for detecting any posterior chamber abnormality, as compared to low (25, 50] gain levels. Thus, incorporating the use of high gain for ocular POCUS exams produces a more effective tool for ocular pathologies in acute care settings and may be particularly valuable in resource-limited settings.

Epidemiology and prevalence of tobacco use in Tehran; a report from the recruitment phase of Tehran cohort study.

INTRODUCTION: Tobacco use is a major health concern worldwide, especially in low/middle-income countries. We aimed to assess the prevalence of cigarette smoking, waterpipe, and pipe use in Tehran, Iran. METHODS: We used data from 8272 participants of the Tehran Cohort Study recruitment phase. Tobacco use was defined as a positive answer to using cigarettes, waterpipes, or pipes. Participants who did not report tobacco use during the interview but had a previous smoking history were categorized as former users. Age- and sex-weighted prevalence rates were calculated based on the national census data, and characteristics of current and former tobacco users were analyzed. RESULTS: Age- and sex-weighted prevalence of current tobacco users, cigarette smokers, waterpipe, and pipe users in Tehran was 19.8%, 14.9%, 6.1%, and 0.5%, respectively. Current tobacco use was higher in younger individuals (35-45 years: 23.4% vs. ≥ 75 years: 10.4%, P < 0.001) and men compared to women (32.9% vs. 7.7% P < 0.001). The prevalence of tobacco use increased with more years of education (> 12 years: 19.3% vs. illiterate: 9.7%, P < 0.001), lower body mass index (< 20 kg/m2: 31.3% vs. ≥ 35 kg/m2: 13.8%, P < 0.001), higher physical activity (high: 23.0% vs. low: 16.4%, P < 0.001), opium (user: 66.6% vs. non-user: 16.5%, P < 0.001), and alcohol use (drinker: 57.5% vs. non-drinker: 15.4%, P < 0.001). Waterpipe users were younger (46.1 vs. 53.2 years) and had a narrower gender gap in prevalence than cigarette smokers (male/female ratio in waterpipe users: 2.39 vs. cigarette smokers: 5.47). Opium (OR = 5.557, P < 0.001) and alcohol consumption (OR = 4.737, P < 0.001) were strongly associated with tobacco use. Hypertension was negatively associated with tobacco use (OR = 0.774, P = 0.005). CONCLUSION: The concerning prevalence of tobacco use in Tehran and its large gender gap for cigarette and waterpipe use warrant tailored preventive policies.

Epidemiology of mental health disorders in the citizens of Tehran: a report from Tehran Cohort Study.

BACKGROUND: Mental health disorders (MHD) impose a considerable burden on public health systems. With an increasing worldwide trend in urbanization, urban mental health stressors are affecting a larger population. In this study, we evaluated the epidemiology of mental health disorders in the citizens of Tehran using the Tehran Cohort Study (TeCS) data. METHODS: We utilized data from the TeCS recruitment phase. A total of 10,247 permanent residents of Tehran metropolitan (aged 15 years and older) were enrolled in the study from March 2016 to 2019 via systematic random sampling from all 22 districts of Tehran. The participant's demographic, socioeconomic, and medical characteristics were evaluated by conducting comprehensive interviews. The standardized Persian version of the General Health Questionnaire version 28 was utilized to assess the mental status of the patients according to four central mental health disorders. RESULTS: Almost 37.1% of Tehran residents suffered mental health problems (45.0% of women and 28.0% of men). The greatest incidence of MHDs was seen in the 25-34 and over 75 age groups. The most common mental health disorders were depression (43%) and anxiety (40%), followed by somatization (30%) and social dysfunction (8.1%). Mental health disorders were more frequent in the southeast regions of the city. CONCLUSIONS: Tehran residents have a significantly higher rate of mental health disorders compared to nationwide studies, with an estimated 2.7 million citizens requiring mental health care services. Awareness of mental health disorders and identifying vulnerable groups are crucial in developing mental health care programs by public health authorities.

Application of Point-of-care Ultrasound for Screening Climbers at High Altitude for Pulmonary B-lines.

INTRODUCTION: High-altitude pulmonary edema (HAPE) occurs as a result of rapid ascent to altitude faster than the acclimatization processes of the body. Symptoms can begin at an elevation of 2,500 meters above sea level. Our objective in this study was to determine the prevalence and trend of developing B-lines at 2,745 meters above sea level among healthy visitors over four consecutive days. METHODS: We performed a prospective case series on healthy volunteers at Mammoth Mountain, CA, USA. Subjects underwent pulmonary ultrasound for B-lines over four consecutive days. RESULTS: We enrolled 21 male and 21 female participants. There was an increase in the sum of B-lines at both lung bases from day 1 to day 3, with a subsequent decrease from day 3 to day 4(P<0.001). By the third day at altitude, B-lines were detectable at base of lungs of all participants. Similarly, B-lines increased at apex of lungs from day 1 to day 3 and decreased on day 4 (P=0.004). CONCLUSION: By the third day at 2,745 meters altitude, B-lines were detectable in the bases of both lungs of all healthy participants in our study. We assume that increasing the number of B-lines could be considered an early sign of HAPE. Point-of-care ultrasound could be used to detect and monitor B-lines at altitude to facilitate early detection of HAPE, regardless of pre-existing risk factors.

Utilization of point-of-care ultrasound among graduates of a 4-year longitudinal medical school ultrasound curriculum.

OBJECTIVE: In 2011, School of Medicine, University of California, Irvine was among the first schools to implement a 4-year ultrasound curriculum. We aimed to find the point-of-care ultrasound (POCUS) utilization pattern among University of California, Irvine alumni. METHODS: We surveyed University of California, Irvine alumni from the class of 2011 and beyond. Survey questions included POCUS reliance, frequency of use, and comfort with image acquisition and interpretation compared with peers. The primary outcomes were self-reported comfort and reliance on POCUS. RESULTS: We received 93 responses from 624 surveyed alumni (response rate, 14.9%), of which 87 were analyzed. Although 46 respondents (52.9%) reported more reliance on POCUS, three (3.4%) relied on it less than their peers. At the same time, 72 (82.7%) and 67 (77.0%) felt more comfortable than their colleagues in obtaining and interpreting POCUS, respectively. No respondents felt less comfortable obtaining or interpreting POCUS than their peers. The frequency of POCUS use correlated directly with the frequency with which POCUS changed the responder's case management (rho, 0.860; P<0.001). POCUS reliance also correlated with respondents' comfort level in obtaining (rho, 0.321; P<0.001) and interpreting (rho, 0.378; P<0.001) POCUS results. CONCLUSION: University of California, Irvine graduates had higher reliance on POCUS than peers in their respective specialties. Their POCUS findings frequently changed their case management.

A HOPE Online Community Peer Support Intervention for Help Seeking: A Randomized Controlled Trial.

OBJECTIVE: A 6-week study was conducted to test the effectiveness of the Harnessing Online Peer Education (HOPE) intervention on anxiety, help seeking (requests for electronic resources [e-resources] on anxiety reduction), and online engagement. METHODS: Three hundred participants with moderate to severe anxiety (i.e., seven-item Generalized Anxiety Disorder scale [GAD-7] scores ≥10) were randomly assigned to social media (i.e., Facebook) groups with or without peer leaders. The study was conducted from April 5 to May 17, 2020. GAD-7 scores, e-resource requests, and online engagement were measured at baseline and at weeks 2, 4, and 6. RESULTS: GAD-7 scores improved in both intervention and control groups, with no difference between conditions. Participants in the intervention group were more likely than those in the control group to request e-resources (OR=10.27, 95% CI=4.52-23.35) and engage online (OR=2.84, 95% CI=1.70-4.76). CONCLUSIONS: The HOPE intervention effectively promoted mental health help-seeking behavior and online engagement.

Opioid prescription patterns in a children's hospital from 2012 to 2016.

STUDY OBJECTIVE: Pain management is a widely discussed topic, especially in the setting of the current opioid epidemic. Previous studies have shown that the use of opioids increased in the adult population. We aimed to look at the use of narcotic and non-narcotic pain medications at a large pediatric hospital to discern if patterns of pediatric pain management changed over time. METHODS: 58,402 analgesic prescriptions of patients 0-21 years of age were analyzed from May 2012 to November 2016. A logistic regression model was fitted to examine the association of age, sex, primary diagnosis, and the length of hospital stay with probability of opioid prescription. RESULTS: 36,560 patients aged 0-21 years (mean: 10.5, median: 11.0, and standard deviation (SD): 7.42) received analgesic pain medications. 21,847 (59.8 percent) patients were prescribed more than one analgesic. There was a male predominance in patients <15 years of age; however, in adolescents >16 years, females constituted 57.1 percent of patients. Data also showed a statistically significant reduction of opioid prescriptions from 2012 to 2016 (p < 0.001). Age and length of hospital stay were directly associated with opioid prescription (p < 0.001). CONCLUSION: Data show that there is a decrease in overall opioid prescriptions among pediatric patients, which may be secondary to new Food and Drug Administration regulations and increased awareness of morbidity associated with opioid use. Not surprisingly, increased hospital stay and increase in age lead to more analgesic prescriptions. Further investigation is needed to determine the differences within opioid prescription patterns.

Evaluation of Adherence to Emergency Department Point-of-Care Ultrasound Documentation and Billing Following Intervention.

Background: Over the past few years, both the scope and utility of point-of-care ultrasound (POCUS) have tremendously expanded in the clinical setting. Despite this growth, few studies have evaluated the compliance, documentation, and billing of POCUS in the emergency department (ED). The objective of this study was to evaluate the compliance of billing and documentation of POCUS and determine if a single, individualized e-mail feedback can help improve billing and documentation. Methods: We performed a 6-week prospective review of ED POCUSs performed. Following this review, all emergency physicians were sent an individualized e-mail regarding their ultrasound performance including the total number of ultrasounds, ultrasounds per shift, and breakdown of specific ultrasound types. Following this intervention, we collected data from an additional 6 weeks regarding ultrasound billing performance. Results: A total of 1532 POCUS scans were recorded for data collection. Eight hundred and five scans were enrolled in the preintervention group and 727 scans in the postintervention group. Twelve different types of POCUS scans were recorded. The preintervention group had documented 484/805 scans resulting in a 60.1% (confidence interval [CI] 56.7%-63.5%) documentation ratio. The postintervention group had documented 521/727 resulting in a 71.7% (CI 68.2%-74.9%) documentation ratio. Conclusion: The implementation of timely quality assurance with continuous billing reminders is essential for the maintenance and fiscal sustainability of an emergency medicine ultrasound program. Future studies should further elucidate and quantify the financial impact of modifiable factors within EDs' ultrasound documentation and billing practices.

The impact of a mindfulness bracelet on emotional affect in medical students: a prospective cohort study.

BACKGROUND: There is concern that negative changes in emotional outlook among medical students may impair the behavior of students, diminish learning, and ultimately affect patient care. Although most medical students begin their professional education with idealism, enthusiasm, and attention to humanity, they often have difficulty balancing their happiness with social and professional responsibilities. The following study aimed to determine if a simple mindfulness reminder (in the form of a bracelet) will impact emotional affect in first-year medical students. The second aim is to better understand the changes in emotional affect as students start medical school. METHODS: First year medical students were invited to participate at the start of the academic year. Baseline survey data and demographic data were obtained prior to participants being given the mindfulness bracelet and a standardized presentation explaining its purpose. Follow-up surveys were obtained at one- and two-month intervals. Statistical analysis was based on sum score of the survey. Change of sum score over time was tested by using repeated measurement analysis. RESULTS: Data collection included 104 students at the initial distribution of the survey. Follow-up surveys were obtained from 78 and 69 students at the first- and second-month mark, respectively. No significant associations were detected between frequency of mindfulness bracelet usage and emotional affect. However, there was a significant decrease in positive affect over the first month of medical school (p < 0.01), followed by a significant recovery in positive affect in the second month of medical school (p < 0.01). Demographic data did not reveal statistically significant differences among demographic groups and progression of emotional affect. CONCLUSIONS: Although the mindfulness bracelet intervention did not yield significant improvement in emotional affect, our results are consistent with other studies demonstrating that the first year of medical school negatively impacts the emotional outlook of students. Future studies are needed to explore practical interventions and to better understand and address the negative effect that early medical school education has on student's emotional state.

Gender Evaluation and Numeric Distribution in Emergency Medicine Residencies (GENDER): A Retrospective Analysis of Gender Ratios Among Residents and Residency Directors from 2014-2017.

INTRODUCTION: While females make up more than half of medical school matriculants, they only comprise about one third of emergency medicine (EM) residents. We examined EM residency cohorts with entering years of 2014-2017 to estimate the ratio of males to females among residents and program leadership to determine what correlation existed, if any, between program leadership and residency gender distributions. METHODS: We identified 171 accredited EM residency programs in the United States with resident cohorts entering between 2014-2017 with publicly available data that were included in the study. The number of male and female residents and program directors were counted. We then confirmed the counts by contacting the programs directly to confirm accuracy of the data collected from program websites. RESULTS: Within the included 171 programs, the overall male to female EM resident ratio was 1.78:1. Individual program ratios ranged from 0.85-8.0. Only eight programs (5.6%) had a female-predominant ratio. Among program directors, the overall male to female ratio was 2.17:1. TThe gender of the program director did not have a statistically significant correlation with the male to female ratio among its residents (P = .93). CONCLUSION: Within 171 residency programs across the US with entering cohorts between 2014-2017, the average male to female ratio among residents is nearly 2:1. No significant correlation exists between the gender distribution among a program's leadership and its residents.
