Identification of gender differences in ultrasound milestone assessments during emergency medicine residency training: a pilot study
Objectives: Prior literature suggests that incongruities between male and female resident's procedural competency may be explained by gender bias during the evaluation process. There are no known studies investigating gender differences in the assessment of ultrasound-based procedural skills among emergency medicine (EM) residents. The purpose of this study was to evaluate for gender differences in ultrasound milestone assessments among EM residents. Methods: This is a retrospective study including EM residents. Milestone assessment data were collected from a total of 3 Accreditation Council for Graduate Medical Education (ACGME) EM residency programs representing a 3-year period The outcome measures included mean milestone levels, milestone levels at baseline and graduation and differences in milestone achievement between female and male EM residents. An unpaired Student's t-test was used to compare milestone scores between female and male residents. Results: A total of 456 ultrasound milestone evaluations were collected from 91 EM residents (34 females [37%] and 57 males [63%]). No significant differences were noted in the overall mean milestone level between females (2.3 +/- 0.6) and males (2.2 +/- 0.6) (P=0.387). There were no significant differences noted in the ultrasound milestone level between females (0.8 +/- 0.6) and males (0.7 +/- 0.7) at baseline (P=0.754). Although it did not reach statistical significance (P=0.197), the increase in the mean ultrasound milestone level from baseline to graduation was greater in males (3.4 +/- 0.7) compared to females (3.1 +/- 0.7). Conclusion: Overall, there were no statistically significant differences in the mean ultrasound milestone levels between females and males. The rate of ultrasound milestone level achievement during EM residency training at our institution had a slight tendency to be higher for males than females in the observed residency programs; however, this also did not reach statistical significance. Possible gender bias while evaluating ultrasound milestone levels needs to be further studied on a larger scale.Open access journal.This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Performance of Ultrasound-guided Peripheral Nerve Blocks by Medical Students After One-day Training Session
Introduction Ultrasound-guided peripheral nerve blocks (USGPNB) are performed by various specialists and are excellent, non-addicting pain control techniques. Alternative pain management approaches are needed to combat opiate abuse. Medical students should be aware of alternative pain management therapies before they begin clinical practice. Objective Our objective was to determine if medical students can identify peripheral nerves under ultrasound and perform a USGPNB after a one-day hands-on training session. Methods This was a cross-sectional study at an academic medical center. The study participants were third-year medical students with minimal prior ultrasound experience. Students were given an introductory lecture highlighting the opiate epidemic and benefits of USGPNB prior to the workshop. The one-day hands-on educational workshop consisted of learning basic sonographic anatomy, indications for USGPNB, and practicing needle guidance under ultrasound guidance. After the educational workshop, students' procedural competency was assessed by ultrasound-trained emergency medicine clinicians. Results A total of 94 participants were included in this study. The average pre-test score was 68.4% (95% confidence interval [CI]; 65.4% to 71.4%). After the one-day educational workshop, the post-test score was 92.8% (95% CI; 90.8% to 94.8%). The average hands-on evaluation score was 84.4% (95% CI; 81.6% to 87.3%). All students agreed that this educational session is a good start to learning about USGPNB, and they felt comfortable identifying the peripheral nerves using ultrasound. On a confidence scale of one (low) through 10 (high), 83% (95% CI; 75.9% to 90.15%) rated their confidence as >= 6. All except one student either agreed that this educational session helped them understand how USGPNB could be integrated into acute pain management. The majority (84% [95% CI; 77% to 91%]) agreed that the session will change how they manage patients' acute pain in their future medical practice. Conclusion Medical students can learn the sonographic anatomy of peripheral nerves and techniques of USGPNB after a one-day educational session.Open access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Point-of-care Head and Neck Sonography for Clinical Problem-solving: Impact of One-day Training Sessions on Medical Student Education
Introduction The curriculum for medical student education is continuously evolving to emphasize knowledge acquisition with critical problem-solving skills. Medical schools have started to implement curricula to teach point-of-care ultrasound skills. To our knowledge, the expansion into head and neck sonography for medical student education is novel and has never been studied. Our objective was to determine the feasibility of implementing point-of-care head and neck sonography and critical problem-solving instruction for medical student education. Methods This was a cross-sectional study enrolling third-year medical students with minimal prior ultrasound experience. A one-day educational curriculum focusing on the use of head and neck ultrasound for clinical problem-solving was integrated into one of the week-long intersessions. The components of point-of-care ultrasound workshop included asynchronous learning, one-hour didactic lecture, followed by a pre-test assessment, then a one-day hands-on workshop, and finally a post-test assessment administered at the end of the training session. Results A total of 123 subjects participated in this study. Ninety-one percent completed the questionnaire prior to the workshop and 83% completed the post-test questionnaire. The level of comfort with using an ultrasound system significantly increased from 31% to 92%. Additionally, the comfort level in interpreting ultrasound images also significantly increased from 21% to 84%. Eighty-nine percent (95% CI, 86%-97%) had an interest in learning ultrasound and would enroll in an optional ultrasound curriculum if given the opportunity. Knowledge of specific ultrasound applications also increased from 60% (after asynchronous learning and lectures) to 95% (after additional hands-on sonographic training). Conclusion At our institution, we successfully integrated point-of-care head and neck sonography and critical problem-solving instruction for medical student education.Open access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Urinary Retention in a Patient With an Artificial Urinary Sphincter: A Case Report of a Rare Cause of Urinary Retention
Urinary retention is the inability to spontaneously void with lower abdominal or suprapubic pain caused by infection, trauma, obstruction, medications, or neurological etiologies. Acute urinary retention (AUR) is a urological emergency often seen in males presenting to the emergency department (ED). AUR is frequently seen in men over the age of 60 and approximately one-third of men over the age of 80. A 61-year-old Spanish-speaking male, with a history of prostate cancer and prostatectomy with the recent insertion of an artificial urethral sphincter two months prior, presented to the ED with urinary retention, complaining of malfunction in his artificial sphincter with worsening abdominal pain, distention, urinary urgency, and nausea. A bladder scan demonstrated 450 ml of urine. Bedside ultrasound (US) showed moderate bilateral hydronephrosis and hydroureter. After consultation with urology, they revealed that the patient did not understand how to properly use his implanted device. Urology experts have recommended minimal urethral instrumentation in patients with artificial urinary sphincters due to the risk of complications. Although we present a rare cause of urinary retention, emergency physicians should avoid catheterization in these patients. Bedside renal ultrasound is useful for the diagnosis of hydronephrosis and hydroureter and confirmation of pump and balloon placement. We recommend a prompt urology consultation. This case is an important example of appropriate postoperative education and close-ended communication. Certified interpreters should be used to avoid communication barriers and complications.Open access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Infective Endocarditis Causing Acute Myocardial Infarction
Endocarditis is a well-known disease, yet septic embolization resulting in myocardial infarction is much rarer and very infrequently diagnosed in the emergency department (ED). Point-of-Care-Ultrasound (POCUS) can be used to confirm clinical suspicion within minutes of patient presentation, thereby expediting patient care. We report the case of a 26-year-old female with known intravenous drug use who presented with altered mental status. Her clinical presentation prompted urgent evaluation in the ED with POCUS which showed a hyperdynamic functioning left ventricle, greater than 50% inferior vena cava collapse, and a large tricuspid valve vegetation. In light of the electrocardiogram (ECG) ST changes suggesting an acute myocardial infarction, the patient was emergently taken to the cardiac catheterization laboratory where coronary angiography revealed multiple coronary emboli. Primary diagnoses included endocarditis due to Staphylococcus, septic pulmonary embolism, and ST-elevated myocardial infarction (STEMI) due to embolic occlusion of the distal left anterior descending artery. Myocardial infarction caused by septic embolization from endocarditis is a rare condition; however, POCUS is a quick, non-invasive tool that can aid the emergency medicine (EM) physician in identifying this life-threatening pathology thereby expediting appropriate care for the patient.Open access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

National Survey of Point-of-Care Ultrasound Scholarly Tracks in Emergency Medicine Residency Programs
Introduction: Residency scholarly tracks are educational programs, designed to help trainees develop an area of expertise. Although the breadth of residency point-of-care ultrasound (POCUS) education has developed considerably in recent years, there is no literature to date describing scholarly tracks specifically in POCUS. In this study we sought to determine the prevalence, characteristics, and outcomes of POCUS scholarly tracks in emergency medicine (EM).
Methods: This was a cross-sectional survey of EM residency programs accredited by the Accreditation Council for Graduate Medical Education. Surveys were distributed between March-August 2020 using a listserv followed by targeted emails to residency and ultrasound leadership. We summarized data using descriptive statistics, and performed logistic regression to identify factors associated with a POCUS scholarly track.
Results: Of 267 residency programs 199 (74.5%) completed the survey. Fifty-seven (28.6%) had a POCUS scholarly track as of the 2019-2020 academic year. Scholarly tracks in POCUS were more common in university-based/academic sites and larger residency programs. Of the 57 programs with POCUS scholarly tracks, 48 (84.2%) required residents to present at least one POCUS lecture, 45 (78.9%) required residents to serve as instructor at a hands-on workshop, and 42 (73.7%) required residents to participate in quality assurance of departmental POCUS scans. Only 28 (49.1%) tracks had a structured curriculum, and 26 (45.6%) required POCUS research. In total, 300 EM residents completed a POCUS scholarly track over the past three academic years, with a median of 4 (2-9) per program. Seventy-five (25.0%) proceeded to a clinical ultrasound fellowship after residency graduation, with a median of 1 (interquartile range 0-2) per program. A total of 139 POCUS-specific abstracts (median 2 [0-3]) and 80 peer-reviewed manuscripts (median 1 [0-2]) were published by scholarly track residents over the past three years.
Conclusion: This survey study describes the current prevalence, characteristics, and outcomes of POCUS scholarly tracks across EM residency programs. The results may inform the decisions of residency programs to create these tracks

Point-of-care Ultrasound Evaluation of Tibial Avulsion Fractures
It can be difficult to diagnose a tibial avulsion fracture based on physical examination alone as findings are often non-specific. Emergency physicians will usually opt for radiography as their initial imaging modality, which has several disadvantages in evaluating tibial avulsion fractures. The objective of this case series is to describe the utility of point-of-care ultrasound (POCUS) in the evaluation of tibial avulsion injuries. A 15-year-old male presented to the emergency department (ED) after sustaining a left knee injury while playing soccer. The clinician had a high suspicion for patellar tendon involvement. A POCUS exam revealed a cortical irregularity and interruption of the left proximal tibia. The patellar tendon was found attached to an avulsed bony portion. Findings were consistent with a tibial tuberosity avulsion fracture. The patient was admitted and scheduled for surgery the following day. Our second case is a 31-year-old male who presented to the ED with a complaint of left knee pain after a 10-foot fall from a ladder. A POCUS exam revealed a bony avulsion over the anterior tibia that was not noted on the initial radiography read by radiology. His patellar tendon showed no evidence of rupture. This led to prompt consultation with orthopedics who evaluated the patient in the ED. Radiographs were reviewed again and it appeared that there was a missed anterior tibial spine fracture. The patient was placed in a knee immobilizer and discharged with instructions to follow up with orthopedics for outpatient surgery. The use of POCUS in the evaluation of these patients led to prompt diagnosis of tibial avulsion injuries, which led to early consultation and appropriate patient management. POCUS allows for expedited diagnosis and appropriate management of patients with tibial avulsion injuries.Open access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Utility of point-of-care musculoskeletal ultrasound in the evaluation of emergency department musculoskeletal pathology
Background: To evaluate the utilization of point-of-care ultrasound (POCUS) for the assessment of emergency department (ED) patients with musculoskeletal symptoms and the impact of musculoskeletal POCUS on medical decision-making and patient management in the ED. Methods: This was a retrospective review of ED patients presenting with musculoskeletal symptoms who received a POCUS over a 3.5-year period. An ED POCUS database was reviewed for musculoskeletal POCUS examinations used for medical decision-making. Electronic medical records were then reviewed for demographic characteristics, history, physical examination findings, ED course, additional imaging studies, and impact of musculoskeletal POCUS on patient management in ED. Results: A total of 264 subjects (92 females, 172 males) and 292 musculoskeletal POCUS examinations were included in the final analysis. Most common symptomatic sites were knee (31.8%) and ankle (16.3%). Joint effusion was the most common finding on musculoskeletal POCUS, noted in 33.7% of the patients, and subcutaneous edema/cobblestoning was found in 10.2% of the patients. Muscle or tendon rupture was found in 2.3% of the patients, and 1.9% of the patients had joint dislocation. Bursitis or bursa fluid was found in 3.4% of patients, and tendonitis/tendinopathy was found in 2.3%. Twenty percent of them were ultrasound-guided musculoskeletal procedures, and most of them (73.3%) were arthrocentesis. Of the included studies, all except three either changed or helped guide patient management as documented in the patients' medical records. Conclusion: Our study findings illustrate the utility of POCUS in the evaluation of a variety of musculoskeletal pathologies in the ED.Open access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
