Working in fours: generational communication in the emergency department.

BACKGROUND: This study examined the conflicts between different generations working in US emergency departments (ED). We sought to record generational differences involving communication preferences, perceived areas of conflict, work motivations, and attitudes regarding work-life balance. METHODS: We developed a survey to assess the physician perspective on generational conflict in the ED. The survey was distributed to members of the American College of Emergency Physicians, a professional organization comprising emergency medicine physicians in the USA. RESULTS: We received 696 completed responses. Men represented 60% of respondents and the largest proportion of respondents were emergency physicians working in community settings (53%); 11% were residents. Generation representation was smallest for Traditionalist (2%) and largest for Gen X (43%). Seventy percent reported observing conflict due to generational communication with the largest frequency being once a week (26%). In the associated open-ended questions, 247 (33%) provided 316 anecdotal descriptions of observed conflict. Responses clustered into seven themes (ordered by frequency): Work Ethic, Treatment Approach, Technology Application, Entitlement, Professionalism, Work Life/Balance, and Communication Style. Comparing Work Ethic responses, 52-70-year-olds reported that younger providers are less interested in "accomplishing anything" while 26-34-year-olds resented that attitude. Respondents completing the open-ended questions regarding preventing and responding to conflict provided some insight into helpful strategies including actions supportive of clear communication and standardized policies and expectations. Only 5% of respondents reported that they had discussed generational communication in department meetings with the odds of a woman reporting conflict being less than males (p = .01). CONCLUSION: Conflicts in the ED in the USA can be attributed to how an individual views the values of someone from another generation. Understanding the frequency and areas of generational conflict in the ED can help medical leaders find strategies to mitigate negative workplace interactions.

A Case Report of Nitrous Oxide-induced Myelopathy: An Unusual Cause of Weakness in an Emergency Department.

INTRODUCTION: Weakness is a common symptom that within itself does not indicate a specific diagnosis. Recreational inhalant use such as nitrous oxide (NO) may not often be disclosed. Additionally, professional or occupational history, such as being a dentist or dental assistant, should be determined because of higher reported rates of NO misuse. Nitrous oxide can cause vitamin B12 deficiency and resulting neuropathy. Nitrous oxide toxicity can have a wide variation of presentations with or without laboratory abnormalities or remarkable imaging findings, which can further complicate a diagnosis of weakness secondary to NO use. CASE REPORT: A 33-year-old female presented to the emergency department with progressive bilateral leg numbness and objective weakness after repeated recreational NO use. After an extensive workup, she was found to have vitamin B12 deficiency and an electromyography study consistent with myeloneuropathy, despite normal imaging. She was prescribed high-dose vitamin B12 therapy and stopped using NO. One year after diagnosis, our patient maintained NO sobriety and had near-complete resolution of prior neurologic deficits. CONCLUSION: The use of recreational inhalant and the patient's occupation should be considered when a patient presents with weakness. Obtaining vitamin B12 and methylmalonic acid levels should be considered for diagnosis. However, NO-induced neuropathy can be seen in patients with normal vitamin B12 and methylmalonic levels and patients do not always have abnormal imaging findings. The healthcare team should consider the varied presentations and findings of substance-induced conditions such as NO toxicity.

Analgesia use in trauma patients at a university teaching hospital in Kigali, Rwanda.

Introduction: While trends in analgesia have been identified in high-income countries, little research exists regarding analgesia administration in low- and middle-income countries (LMIC). This study evaluates analgesia administration and clinical characteristics among patients seeking emergency injury care at University Teaching Hospital-Kigali in Kigali, Rwanda. Methods: This retrospective, cross-sectional study utilized a random sample of emergency center (EC) cases accrued between July 2015 and June 2016. Data was extracted from the medical record for patients who had an injury and were ≥ 15 years of age. Injury-related EC visits were identified by presenting complaint or final discharge diagnosis. Sociodemographic information, injury mechanism and type, and analgesic medications ordered and administered were analyzed. Results: Of the 3,609 random cases, 1,329 met eligibility and were analyzed. The study population was predominantly male (72%) with a median age of 32 years and range between 15 and 81 years. In the studied sample, 728 (54.8%) were treated with analgesia in the EC. In unadjusted logistic regression, only age was not a significant predictor of receiving pain medication and was excluded from the adjusted analysis. In the adjusted model, all predictors remained significant, with being male, having at least one severe injury, and road traffic accident (RTA) as injury mechanism being significant predictors of analgesia administration. Conclusion: In the study setting of injured patients in Rwanda, being male, involved in RTA or having more than one serious injury was associated with higher odds of receiving pain medication. Approximately half of the patients with traumatic injuries received pain medications, predominantly opioids with no factors predicting whether a patient would receive opioids versus other medications. Further research on implementation of pain guidelines and drug shortages is warranted to improve pain management for injured patients in the LMIC setting.

Right-sided weakness in a Rwandan patient with untreated Tetralogy of Fallot.

BACKGROUND: Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease encountered in pediatrics with surgical repair being the definitive treatment. Long-term survival after surgical repair has improved; however, reported mortality rates in untreated TOF are significant. Associated complications include neurological sequelae such as brain abscess and stroke. In countries without early intervention for congenital heart disease (including TOF), delayed presentations and complications require recognition by healthcare workers. CASE PRESENTATION: A 22-year-old male with a history of untreated TOF presented to Rwanda's tertiary university hospital, University Teaching Hospital of Kigali, with acute right-sided hemiparesis. Diagnostic imaging identified a left-sided brain lesion consistent with brain abscess and cardiac mass, concerning endocardial vegetation. He was managed with intravenous antibiotics but subsequently died due to complications of septicemia. DISCUSSION: In countries where surgical repair of TOF is not available, early recognition and medical management are key in temporizing the development of devastating sequelae. Describing the prevalence of CHD in Rwanda is urgent, requiring further research by which effective prevention and treatment strategies can be developed.

Chest trauma epidemiology and emergency department management in a tertiary teaching hospital in Kigali, Rwanda.

Introduction: Chest trauma is a major contributor to injury morbidity and mortality, and understanding trends is a crucial part of addressing this burden in low- and middle-income countries. This study reports the characteristics and emergency department (ED) management of chest trauma patients presenting to Rwanda's national teaching hospital in Kigali. Methods: This descriptive analysis included a convenience sample of patients presenting to a single tertiary hospital ED with chest trauma from June to December 2017. Demographic data were collected as well as injury mechanism, thoracic and associated injuries, types of imaging obtained, and treatments performed. Chart review was conducted seven days post-admission to follow up on outcomes and additional diagnoses and interventions. Incidences were calculated with Microsoft Excel. Results: Among the 62 patients included in this study, 74% were male, and mean age was 35 years. Most patients were injured in road traffic crashes (RTCs) (68%). Common chest injuries included lung contusions (79% of cases), rib fractures (44%), and pneumothoraces (37%). Head trauma was a frequent concurrent extra-thoracic injury (61%). Diagnostic imaging primarily included E-FAST ultrasound (92%) and chest x-ray (98%). The most common therapies included painkillers (100%), intravenous fluids (89%), and non-invasive oxygen (63%), while 29% underwent invasive intervention in the form of thoracostomy. The majority of patients were admitted (81%). Pneumonia was the most common complication to occur in the first seven days (32% of admitted patients). Ultimately, 40% of patients were discharged home within seven days of presentation, 50% remained hospitalized, and 5% died. Conclusion: This study on the epidemiology of chest trauma in Rwanda can guide injury prevention and medical training priorities. Efforts should target prevention in young males and those involved in RTCs. ED physicians in Rwanda need to be prepared to diagnose and treat a variety of chest injuries with invasive and noninvasive means.

Seasonal influence of tuberculosis diagnosis in Rwanda.

BACKGROUND: Tuberculosis (TB) remains a major global health concern. Previous research reveals that TB may have a seasonal peak during the spring and summer seasons in temperate climates; however, few studies have been conducted in tropical climates. This study evaluates the influence of seasonality on laboratory-confirmed TB diagnosis in Rwanda, a tropical country with two rainy and two dry seasons. METHODS: A retrospective chart review was performed at the University Teaching Hospital-Kigali (CHUK). From January 2016 to December 2017, 2717 CHUK patients with TB laboratory data were included. Data abstracted included patient demographics, season, HIV status, and TB laboratory results (microscopy, GeneXpert, culture). Univariate and multivariable logistic regression (adjusted for age, gender, and HIV status) analyses were performed to assess the association between season and laboratory-confirmed TB diagnoses. RESULTS: Patients presenting during rainy season periods had a lower odds of laboratory-confirmed TB diagnosis compared to the dry season (aOR=0.78, 95% CI 0.63-0.97, p=0.026) when controlling for age group, gender, and HIV status. Males, adults, and people living with HIV were more likely to have laboratory-confirmed TB diagnosis. On average, more people were tested for TB during the rainy season per month compared to the dry season (120.3 vs. 103.3), although this difference was not statistically significant. CONCLUSION: In Rwanda, laboratory-confirmed TB case detection shows a seasonal variation with patients having higher odds of TB diagnosis occurring in the dry season. Further research is required to further elucidate this relationship and to delineate the mechanism of season influence on TB diagnosis.

Intimate Partner Violence Experienced by Physicians.

PURPOSE: World Health Organization (WHO) defines intimate partner violence (IPV) as physical, sexual or psychological harm caused by an intimate partner or ex-partner. There are few studies describing interpersonal violence (IPV) among physicians. Our study describes IPV experienced by U.S. physicians. METHODS: This was a multicenter survey administered to 4 physician groups in 2015 to 2016. In total 400 respondents returned survey results. Measures included current IPV, childhood abuse, mental health, professional role, and demographics. RESULTS: IPV was reported by 24% of respondents. The most frequent abuses reported were: verbal (15%), physical (8%) followed by sexual abuse (4%) and stalking (4%). Logistic regression model found that IPV was more likely to be reported by older participants (aged 66-89), those who experienced childhood abuse, working less than full time, and had been diagnosed with a personality disorder. Women and Asian Americans reported slightly higher IPV rates. CONCLUSIONS: Our study has implications for both medical education and intervention development. Universal screening and education that addresses clinical implications when treating peers who experience IPV are needed. Workplace interventions that consider unique physician characteristics and experiences are needed, as well as programs that support sustained recovery. This is the first survey to our knowledge that confirms that physicians experience IPV at a rate consistent or higher than the national level. We developed a standardized instrument to assess IPV in male and female physicians at various career stages. We also identified significant predictors that should be included in IPV screening of potential physician victims.

Evaluation of a modified South African Triage Score as a predictor of patient disposition at a tertiary hospital in Rwanda.

BACKGROUND: Triage is essential for efficient and effective delivery of care in emergency centers (ECs) where numerous patients present simultaneously with varying acuity of conditions. Implementing EC triage systems provides a method of recognizing which patients may require admission and are at higher risks for poor health outcomes. Rwanda is experiencing increased demand for emergency care; however, triage has not been well-studied. The University Teaching Hospital of Kigali (UTH-K) is an urban tertiary care health center utilizing a locally modified South African Triage Score (mSATS) that classifies patients into five color categories. Our study evaluated the utility of the mSATS tool at UTH-K. METHODS: UTH-K implemented mSATS in April 2013. All patients aged 15 years or older from August 2015 to July 2016 were eligible for inclusion in the database. Variables of interest included demographic information, mSATS category, patient case type (trauma or medical), disposition from the ED and mortality. RESULTS: 1438 cases were randomly sampled; the majority were male (61.9%) and median age was 35 years. Injuries accounted for 56.7% of the cases while medical conditions affected 43.3%. Admission likelihood significantly increased with higher triage color category for medical patients (OR: Yellow = 3.61, p < .001 to Red (with alarm) = 7.80, p < .01). Likelihood for trauma patients, however, was not significantly increased (OR: Yellow = .84, p = .75 to Red (with alarm) = 1.50, p = .65). Mortality rates increased with increasing triage category with the red with alarm category having the highest mortality (7.7%, OR 18.91). CONCLUSION: The mSATS tool accurately predicted patient disposition and mortality for the overall ED population. The mSATS tool provided useful clinical guidance on the need for hospital admission for medical patients but did not accurately predict patient disposition for injured patients. Further trauma-specific triage studies are needed to improve emergency care in Rwanda.

Yogaman: An Inexpensive, Anatomically-detailed Chest Tube Placement Trainer.

INTRODUCTION: Opportunities for chest tube placement in emergency medicine training programs have decreased, making competence development and maintenance with live patients problematic. Available trainers are expensive and may require costly maintenance. METHODS: We constructed an anatomically-detailed model using a Halloween skeleton thorax, dress form torso, and yoga mat. Participants in a trial session completed a survey regarding either their comfort with chest tube placement before and after the session or the realism of Yogaman vs. cadaver lab, depending on whether they had placed <10 or 10 or more chest tubes in live patients. RESULTS: Inexperienced providers reported an improvement in comfort after working with Yogaman, (comfort before 47 millimeters [mm] [interquartile ratio {IQR}, 20-53 mm]; comfort after 75 mm [IQR, 39-80 mm], p=0.01). Experienced providers rated realism of Yogaman and cadaver lab similarly (Yogaman 79 mm [IQR, 74-83 mm]; cadaver lab 78 mm [IQR, 76-89 mm], p=0.67). All evaluators either agreed or strongly agreed that Yogaman was useful for teaching chest tube placement in a residency program. CONCLUSION: Our chest tube trainer allowed for landmark identification, tissue dissection, pleura puncture, lung palpation, and tube securing. It improved comfort of inexperienced providers and was rated similarly to cadaver lab in realism by experienced providers. It is easily reusable and, at $198, costs a fraction of the price of available commercial trainers.

Effective Educational Videos in Emergency Medicine.

Video is a popular format for teaching and learning online. Emergency medicine (EM) has been a leader in online learning and EM educators may wish to use video to teach. The creation of online video content is fraught with pitfalls that may make videos less effective. We review notable theory and evidence regarding effective use of video for education in EM with international considerations.

Deciding to lead: a qualitative study of women leaders in emergency medicine.

BACKGROUND: The aim of this study is to highlight career paths of senior women leaders in academic emergency medicine (EM) to encourage younger women to pursue leadership. METHODS: This was a qualitative study using semi-structured interviews with female EM leaders. We interviewed 22 recognized female leaders selected using criterion-based sampling and a standardized script of open-ended questions derived from the Intelligent Career Model. Questions were related to job purpose, skills, and networking. Interviews were transcribed verbatim and three trained reviewers analyzed transcripts following grounded theory principles and using Dedoose®. Researchers used an iterative process over several meetings to produce the final set of codes and themes. RESULTS: Our iterative process identified four themes: women leaders made an intentional decision to pursue opportunities to influence emergency medicine, women sought out natural mentors and sponsors to facilitate career development, women leaders intentionally planned their out of work life to support their leadership role, and an important focus for their work was to help others achieve excellence. CONCLUSIONS: Our study provides insights from senior female leaders in EM; supporting the value of women pursuing leadership. There is a widely acknowledged need to diversify leadership and support gender-specific needs to develop women leaders in medicine. Becoming a woman leader in EM means making intentional decisions and taking risks. Leaders found benefits in natural mentors and sponsors. Those relationships have power to change the trajectory of emerging women leaders by identifying and reinforcing potential. Work/life balance remains an area which requires intentional planning. Woman leaders encourage succession planning and corroborate the need for increasing the percentage of women leaders to benefit the organizational culture. Leadership in academic medicine is changing with reorientation of a largely autocratic, vertically oriented hierarchy into a more democratic, consensus-driven, and horizontally organized management structure which should complement the strengths women bring to the leadership table.

Developing and implementing a global emergency medicine course: Lessons learned from Rwanda.

BACKGROUND: There is a growing demand by medical trainees for meaningful, short-term global emergency medicine (EM) experiences. EM programs in high-income countries (HICs) have forged opportunities for their trainees to access this experience in low-and middle-income countries (LMICs). However, few programs in LMICs have created and managed such courses. As more LMICs establish EM programs, these settings are ideal for developing courses beneficial for all participants. We describe our experience of creating and implementing a short-term global EM course in Rwanda. OBJECTIVES: The objectives of this study were to (1) provide EM trainees from HICs with an opportunity to observe global clinical practice and to learn from local experts, (2) provide EM trainees from an LMIC with an opportunity to share their expert knowledge and skills with HIC trainees, (3) create a sustainable model for a short-term global EM course in an LMIC context. METHODS: A global EM curriculum and course were developed in Rwanda, entitled EM in the Tropics Emergency Medicine in the Tropics (EMIT). The following topics were covered: EM systems development, public health, trauma/triage, pediatrics, disaster management, and tropical EM. A one-and two-week course program was created and implemented. RESULTS: EMIT participants rotated through pediatric and adult EDs, Intensive Care Unit, trauma surgery, internal medicine, emergency medical services, and ultrasound training. Activities included bedside teaching, case presentations, ultrasound practice, group lectures, simulation and skills workshops, and a rotation to a district hospital. A total of 11 participants attended: six for both weeks and five for 1 week. The course raised $5000 USD, which was dedicated in full to sponsoring local EM residents to attend international conferences. DISCUSSION: The EMIT course in Rwanda achieved its objectives of teaching and learning between all participants. Benefits of this in-person experience for both visiting and local participants are clear in clinical, intercultural, and professional ways. CONCLUSION: Our experience of developing and implementing EMIT in Rwanda demonstrates that EM programs in LMICs can provide short-term global EM courses that are not only beneficial to all participants, but also logistically and financially sustainable.

Comparison of the finger counting method, the Broselow tape and common weight estimation formulae in Filipino children after Typhoon Haiyan.

OBJECTIVES: We sought to evaluate commonly used paediatric weight estimation techniques in a sample of children in the Philippines. METHODS: We prospectively collected age, height and weight data for a sample of 207 children aged 1-9 years seen during a medical aid trip. Weights were estimated using the finger counting method, the Broselow method and four formulae. Bland-Altman analysis was performed to evaluate agreement with measured weight. RESULTS: Mean difference and range of agreement in kilograms were as follows: 0.6 (95% CI 0.1-1.1) and 14.9 (95% CI 13.1-16.7) for the Broselow method; 1.1 (95% CI 0.5-1.7) and 17.3 (95% CI 15.2-19.3) for the traditional APLS formula; 3.1 (95% CI 2.4-3.7) and 18.6 (95% CI 16.4-20.8) for the finger counting method; 4.0 (95% CI 3.2-4.8) and 23.1 (95% CI 20.3-25.8) for the updated APLS method; 5.1 (95% CI 4.4-5.8) and 21.1 (95% CI 18.6-23.6) for the Luscombe formula; and 5.3 (95% CI 4.5-6.1) and 22.5 (95% CI 20-25.2) for the Best Guess formulae. CONCLUSIONS: The Broselow tape and the traditional APLS formula performed best in our sample. The finger counting method also outperformed newer weight estimation formulae. 'Updated' age-based formulae created recently in developed countries should not be used in disaster relief efforts in the Philippines. Caution should be used when applying these formulae to other developing countries and in disaster response.

The flipped classroom: a modality for mixed asynchronous and synchronous learning in a residency program.

INTRODUCTION: A "flipped classroom" educational model exchanges the traditional format of a classroom lecture and homework problem set. We piloted two flipped classroom sessions in our emergency medicine (EM) residency didactic schedule. We aimed to learn about resident and faculty impressions of the sessions, in order to develop them as a regular component of our residency curriculum. METHODS: We evaluated residents' impression of the asynchronous video component and synchronous classroom component using four Likert items. We used open-ended questions to inquire about resident and faculty impressions of the advantages and disadvantages of the format. RESULTS: For the Likert items evaluating the video lectures, 33/35 residents (94%, 95% CI 80%-99%) responded that the video lecture added to their knowledge about the topic, and 33/35 residents felt that watching the video was a valuable use of their time. For items evaluating the flipped classroom format, 36/38 residents (95%, 95% CI 82%-99%) preferred the format to a traditional lecture on the topic, and 38/38 residents (100%, 95% CI 89%-100%) felt that the small group session was effective in helping them learn about the topic. Most residents preferred to see the format monthly in our curriculum and chose an ideal group size of 5.5 (first session) and 7 (second session). Residents cited the interactivity of the sessions and access to experts as advantages of the format. Faculty felt the ability to assess residents' understanding of concepts and provide feedback were advantages. CONCLUSION: Our flipped classroom model was positively received by EM residents. Residents preferred a small group size and favored frequent use of the format in our curriculum. The flipped classroom represents one modality that programs may use to incorporate a mixture of asynchronous and interactive synchronous learning and provide additional opportunities to evaluate residents.

Interrater reliability of cardiac output measurements by transcutaneous Doppler ultrasound: implications for noninvasive hemodynamic monitoring in the ED.

INTRODUCTION: Hemodynamic monitoring is an important aspect of caring for the critically ill patients boarding in the emergency department (ED). The purpose of this study is to investigate the interrater agreement of noninvasive cardiac output measurements using transcutaneous Doppler ultrasound technique. METHODS: This is a prospective observational cohort study performed in a 32-bed adult ED of an academic tertiary center with approximately 65000 annual patient visits. Patients were enrolled after verbal consent over a 7-month period. The raters were ED personnel involved in patient care. Paired measurements of cardiac index (CI) and stroke volume index (SVI) were obtained from a transcutaneous Doppler ultrasound cardiac output monitor. RESULTS: A convenience sample of 107 (50 women and 57 men) patients with a median age of 49 (32, 62) years was enrolled. One hundred two paired measurements were performed in 91 patients in whom adequate Doppler ultrasound signals were obtainable. The raters included 35 emergency medicine attending physicians, 31 emergency medicine residents, 80 medical students, 47 nurses, and 11 emergency medical technicians. Cardiac index range was 0.6 to 5.3 L/min per square meter, and SVI range was 7.7 to 63.0 mL/m(2). The correlation of CI measurements between 2 raters was good (r(2) = 0.87; 95% confidence interval, 0.86-1.00; P < .001). Likewise, SVI measurements between 2 raters also showed acceptable correlation (r(2) = 0.84; 95% confidence interval, 0.81-0.96; P < .001). Interrater reliability was strong for CI (kappa = 0.83 with 92.2% agreement) and SVI measurements (kappa = 0.72 with 88.2% agreement). Most patients had an interrater difference below 10% in CI and SVI measurements. CONCLUSIONS: Emergency department personnel, regardless of their role in patient care, are able to obtain reliable cardiac output measurements in ED patients over a wide range of CI and SVI. Transcutaneous Doppler ultrasound technique may be an alternative to traditional invasive hemodynamic monitoring of critically ill patients presenting to the ED.
