Skills acquisition for novice learners after a point-of-care ultrasound course: does clinical rank matter?

Relation Between Ultrasonographic Measurements of the Biceps Brachii and Total Muscle Mass in Older Hospitalized Persons: A Pilot Study

Objectives

To assess the link between ultrasonographic measurements of the biceps brachii and total muscle mass measured by bio-impedancemetry in hospitalized older patients.

Methods

A prospective observational study was conducted. The study included patients older than 65 years admitted in internal medicine, acute geriatrics, orthogeriatrics and rehabilitation departments. All measurements, ultrasonographic measurements and muscle mass and function by bio-impedancemetry and dynamometry, were taken within the first 48 hours of admission.

Results

In total 19 patients were included, the mean age was 85.4 ± 3.9 years and 7 (36.8%) were females. Very strong direct correlations were obtained in the entire cohort in both biceps brachii cross-sectional area and muscle thickness with skeletal muscle mass displayed in kilograms.

Conclusion

Biceps brachii looks like a very good muscle measuring tool: easy, comfortable, fast, good correlated with total body muscle mass. This muscle could effectively be used for the assessment of muscle mass in the diagnosis of sarcopenia since it reflects muscle mass precisely, however more studies are needed to provide reference values in all age cohorts.

Diaphragm Ultrasonography: Reference Values and Influencing Factors for Thickness, Thickening Fraction, and Excursion in the Seated Position

INTRODUCTION

Measurements of diaphragm function by ultrasonography are affected by body position, but reference values in the seated position have not been established for an Asian population. This study aimed to determine reference values for diaphragm thickness, thickening fraction, and dome excursion by ultrasonography and to investigate the effects of sex, height, and body mass index.

METHODS

Diaphragm ultrasonography was performed on 109 seated Japanese volunteers with normal respiratory function who were enrolled between March 2022 and January 2023. Thickness, thickening fraction, and excursion were measured. Reference values and the measurement success rate were calculated. Multivariate analysis adjusted for sex, height, and body mass index was performed.

RESULTS

The measurement success rate was better for thickness than for excursion. The mean (lower limit of normal) values on the right/left sides were as follows. During quiet breathing, thickness at end expiration(mm) was 1.7 (0.9)/1.6 (0.80), thickening fraction(%) was 50 (0.0)/52 (0.0), and excursion(cm) was 1.7 (0.5)/1.9 (0.5). During deep breathing, the thickening fraction was 111 (24)/107 (22), and the excursion was 4.4 (1.7)/4.1 (2.0). In multivariate analysis, body mass index was positively associated with thickness but not with the thickening fraction.

CONCLUSION

The reference values in this study were smaller than those in previous reports from Europe. Considering that thickness is influenced by body mass index, using Western reference values in Asia, where the average body mass index is lower, might not be appropriate. The thickening fraction in deep breathing is unaffected by other items and can be used more universally.

Is Ultrasound-guided or Landmark-guided Intra-articular Lidocaine Injection More Effective for Pain Control in Anterior Shoulder Dislocation Reduction? A Randomized Controlled Trial

BACKGROUND

Effective pain control during reduction of shoulder dislocation is essential for patient comfort. However, there is a lack of comprehensive research comparing the efficacy of different pain management techniques, specifically landmark-guided and ultrasound-guided intra-articular analgesic injections.

QUESTIONS/PURPOSES

Among patients undergoing closed reduction of a shoulder dislocation, were there differences between an intra-articular shoulder injection placed using anatomic landmarks and an ultrasound-guided intra-articular injection in terms of (1) pain before versus after the injection and pain before injection versus after the reduction, or (2) length of stay in the emergency department and complications of the procedure?

METHODS

Between August 2021 and March 2023, 28 patients with anterior shoulder dislocation were treated at the emergency department of a tertiary referral care center. They were randomly assigned to either the landmark-guided or ultrasound-guided intra-articular lidocaine injection group. Differences in pain levels between preinjection and postinjection, preinjection and postreduction, length of hospital stay, and complications were assessed and compared between the two groups. Patients were followed for 2 weeks.

RESULTS

There were no between-group differences in terms of age, gender, baseline pain score, and any other relevant factors. There were no differences between the groups in terms of pain reduction between preinjection and postinjection (landmark-guided: ΔVAS 2.8 ± 1.1, ultrasound-guided: ΔVAS 2.9 ± 1.0, mean difference -0.14 [95% confidence interval -0.97 to 0.68]; p = 0.72) or between preinjection and postreduction (landmark-guided: ΔVAS 6.6 ± 2.1, ultrasound-guided: ΔVAS 5.8 ± 1.8, mean difference 0.79 [95% CI -0.74 to 2.31]; p = 0.30). There were no differences in length of stay in the emergency department (landmark-guided: 162 ± 38 minutes, ultrasound-guided: 184 ± 73 minutes, mean difference 22 minutes [95% CI -67 to 24]; p = 0.33), and no complications were reported in either group during the 2-week follow-up period.

CONCLUSION

The results of the landmark-guided technique were not different from those of ultrasound-guided injection in terms of lower pain levels, length of stay, and complications. These findings provide valuable guidance for orthopaedic surgeons, enabling them to make informed decisions based on their expertise and available resources.

Development of a national point-of-care ultrasound training course for physicians in Japan: A 3-year evaluation

Purpose: Point-of-care ultrasound (POCUS) allows bedside clinicians to acquire, interpret, and integrate ultrasound images into patient care. Although the availability of POCUS training courses has increased, the educational effectiveness of these courses is unclear. Methods: From 2017 to 2019, we investigated the educational effectiveness of a standardized 2-day hands-on POCUS training course and changes in pre- and post-course exam scores in relationship to participants' (n = 571) clinical rank, years of POCUS experience, and frequency of POCUS use in clinical practice. Results: The mean pre- and post-course examination scores were 67.2 (standard deviation [SD] 12.3) and 79.7 (SD 9.7), respectively. Higher pre-course examination scores were associated with higher clinical rank, more years of POCUS experience, and more frequent POCUS use (p < 0.05). All participants showed significant changes in pre- to post-course exam scores. Though pre-course scores differed by clinical rank, POCUS experience, and frequency of POCUS use, differences in post-course scores according to participant baseline differences were non-significant. Conclusion: A standardized hands-on POCUS training course is effective for improving POCUS knowledge regardless of baseline differences in clinical rank, POCUS experience, or frequency of POCUS use. Future studies shall evaluate changes in POCUS use in clinical practice after POCUS training.

Implementation and Assessment of a Hybrid Training Course on Point-of-Care Pediatric Ultrasound in Vietnam During the COVID-19 Pandemic

Background As point-of-care ultrasound (POCUS) has gained popularity, some educational guidelines have been developed. However, in Vietnam, no training course in pediatric POCUS has yet been developed. This was challenging, especially during the COVID-19 pandemic. Objectives This study aimed to implement a three-month hybrid training course for pediatric POCUS training in Vietnam using both online and face-to-face hands-on sessions and to assess participants' self-efficacy level and change in their attitudes towards pediatric POCUS. Methods A hybrid training course in pediatric POCUS was implemented at a children's hospital in Vietnam. This study developed a standardized training course, including online learning, live lectures, hands-on sessions, and skill assessment based on the POCUS consensus educational guidelines. Physicians interested in pediatric POCUS were recruited for participation. They completed a self-evaluation survey before and after the course using a Likert score to assess their background, self-efficacy in performing POCUS, overall satisfaction with the course, and change in their attitudes towards POCUS three months after the course. Results A total of 19 physicians participated in the course. The mean post-training self-efficacy score was significantly higher than the pre-course assessment score: 73.1 (standard deviation (SD): 7.2) vs. 48.9 (SD: 12.5) (p <0.05). The efficacy level was retained three months after the course. Furthermore, overall satisfaction with the course was high at 9.5 (SD: 0.6). After the course, almost all participants strongly agreed to increase the use of POCUS in their clinical practice. Conclusion A hybrid training course in pediatric POCUS was successfully implemented in Vietnam and found the participants' self-efficacy level to be significantly higher after the course and the effect to be retained after the course. The training course could positively affect the participants' attitudes towards POCUS, encouraging them to use POCUS more frequently in their clinical practice.

Effectiveness of point of care ultrasound (POCUS) simulation course and skills retention for Japanese nurse practitioners

BACKGROUND

In Japan, the nurse practitioner (NP) system has only been in place for a short time, and there is no ultrasound (US) simulation course for NPs. Therefore, NPs may have to attend US simulation courses for physicians. We evaluated whether US simulation course for physicians lead to improved image acquisition and interpretation amongst NPs and, if so, if these changes would be maintained over time.

METHODS

A 2-day point-of-care ultrasound (POCUS) course designed for physicians in cardiac US, lung US, lower extremity deep vein thrombosis (DVT) US, and abdominal US was held for Japanese nurse practitioners (JNP) and JNP trainees in 2018 and 2019. Participants kept a record of the number of US examinations they performed for 3 months before and 3 months after the course. The number of US exams performed was grouped into six categories. All participants underwent pre-course, immediate post-course, and 4-month post-course testing to assess image interpretation skills, image acquisition skills, and confidence.

RESULTS

Thirty-three participants from 21 facilities completed the program. Before and immediately after the course, test scores of the image interpretation test, image acquisition test, and confidence increased significantly (37.1, 72.6: P < 0.001), (13.7, 53.6: P < 0.001), and (15.8, 35.7: P < 0.001), respectively. Comparing the follow-up tests immediately after the course and 4 months later, there was no decrease in scores on the image interpretation test, the image acquisition test, or confidence (72.6, 71.8: P = 1.00) (53.6, 52.9: p = 1.00) (35.7, 33.0: P = 0.34). There was a statistically significant increase (P < 0.001) in both the total number of ultrasound examinations and in the number of ultrasound examinations by category (cardiac, lung, lower extremity DVT, and abdominal) in the 3 months before and 3 months after the course.

CONCLUSIONS

The POCUS simulation course for physicians is useful for JNPs to acquire US examination skills even if it is not arranged for JNPs. Image interpretation skill, image acquisition skill, and confidence improved significantly and were maintained even after 4 months of the course. It leads to behavioral changes such as increasing the number of US examinations in daily practice after the course.

"Teaching old dogs new tricks" - POCUS Education for Senior Faculty

Point of Care Ultrasound (POCUS) is a growing diagnostic modality across a variety of specialties and is increasingly being taught in undergraduate medical education. Uptake within internal medicine has been slow but is becoming more commonplace. Training of extant hospital medicine faculty, including senior members, in POCUS is an unmet need in graduate medical education with significant pedagogical and patient safety implications. With this in mind, we created a training program for the core teaching faculty at our academic internal medicine residency program. The experiential, hands-on curriculum explored the reasoning behind concepts and emphasized psychological safety for senior faculty learners and was successful and well-received. In our piece, we aim to explore the existing literature around training this unique population in POCUS and report on our single-center experience. We also provide a framework for how our program succeeded, collate tips derived from the expert ultrasound teachers and list pearls learned while teaching these experienced educators. Although this worthwhile effort requires planning and support, it was appreciated even by senior faculty.

Short-term educational value of online neuromuscular ultrasound courses

INTRODUCTION/AIMS

We have previously reported that online neuromuscular ultrasound courses are feasible and were found to be useful by most survey respondents. However, our previous report lacked objective assessment of the educational value of the courses. Therefore, we aimed in this study to evaluate the learning outcomes of online neuromuscular ultrasound courses.

METHODS

Each of the basic and advanced courses featured one pre- and two post-course online knowledge tests. The percentage of corrected answers and the participants' scores in the three tests were calculated and compared.

RESULTS

A total of 153 out of 277 course participants answered the course test. The mean percentage of correct answers were significantly higher in the second and first post-course tests compared to the pre-course test (Basic course test: 80.2 ± 14.8%, 75.5 ± 15.9%, 64.3 ± 19.1%, respectively; Advanced course test: 80.9 ± 20.1, 78.9 ± 15.2%, 69.5 ± 20.2%, respectively). The mean scores of the participants in the basic course test significantly improved in the first and second post-course tests (from 66.6% to 77.5% and from 67.2% to 80.2%, respectively) whereas those of the participants in the advanced course test significantly improved in the first post-course test only (from 76.3% to 85.4%).

DISCUSSION

This report demonstrates the capability of online neuromuscular ultrasound courses, particularly the basic-level courses, to enhance knowledge. This information can further help integrate virtual neuromuscular ultrasound teaching as a standard complementary educational format together with supervised in-person or remote hands-on training.

Point-of-care ultrasound needs assessment in a paediatric acute care setting in Malawi

OBJECTIVE

To describe the use of point-of-care ultrasound (POCUS) in an acute-care paediatric setting in Malawi, including clinical indications, types of examinations and frequency of positive findings.

METHODS

Retrospective, cross-sectional study of a convenience sample of POCUS examinations performed in one tertiary referral hospital in Lilongwe, Malawi over 1 year. POCUS examinations were performed by Paediatric Emergency Medicine physician consultants as part of routine clinical practice and at the request of local clinicians. Images were saved along with the clinical indication and physician interpretation for quality review. Ultrasounds performed by the radiology department and those examinations that were technically faulty, missing clinical application or interpretation were excluded.

RESULTS

In total, 225 ultrasounds of 142 patients were analysed. The most common clinical indications for which examinations were completed were respiratory distress (23%), oedema (11.7%) and shock/arrest (6.2%). The most common examinations performed were cardiac (41.8%) and lung (15.1%), focused assessment with sonography in trauma (FAST; 12.9%) and ultrasound-guided procedural examinations (9.8%). Pathology was identified in 68% of non-procedural examinations. Cardiac examinations demonstrated significant pathology, including reduced cardiac function (12.8%), gross cardiac structural abnormality (11.8%) and pericardial effusion (10.3%).

CONCLUSIONS

POCUS was used for both clinical decision-making and procedural guidance, and a significant number of POCUS examinations yielded positive findings. Thus, we propose that cardiopulmonary, FAST and procedural examinations should be considered in future for the POCUS curriculum in this setting.

Virtual anatomy and point-of-care ultrasonography integration pilot for medical students

Despite its significant clinical use, there is no standardized point-of-care ultrasonography (POCUS) curriculum in undergraduate medical education. As Covid-19 abruptly mandated the use of virtual education, instructors were challenged to incorporate and improve POCUS education within these new constraints. It was hypothesized that integrating POCUS into anatomy via brief video lessons and a subsequent interactive virtual lesson would lead to an objective understanding of POCUS concepts, improved understanding of the corresponding anatomy, and subjective improvement of student confidence with POCUS. A cross-sectional descriptive study assessed first-year medical students' perspectives and performance before and after the interventions (n = 161). The intervention was split into two parts: (1) three optional 10-minute POCUS videos that reinforced anatomy concepts taught in the laboratory sessions, and (2) a subsequent two-hour interactive virtual session reviewing POCUS and anatomy concepts. Students completed a knowledge and confidence assessment tool before and after the interactive session. Survey responses (n = 51) indicated that 94% of students felt the optional videos improved their understanding of POCUS and were educationally valuable. One half of medical students (50%) indicated that the demonstrations improved their anatomy understanding. Initial self-reported confidence was low after the optional video lessons, despite an average score of 58% on the knowledge assessment (n = 130). However, confidence increased significantly along with an increase in score performance to 80% after the interactive session (n = 39, P < 0.01). Results suggest that the virtual integration pilot enhanced student learning of both anatomy and POCUS.

The feasibility and reliability of measuring forearm muscle thickness by ultrasound in a geriatric inpatient setting: a cross-sectional pilot study

Background

Given the potential benefits of introducing ultrasound in the clinical assessment of muscle disorders, this study aimed to assess the feasibility and reliability of measuring forearm muscle thickness by ultrasound in a geriatric clinical setting.

Methods

Cross-sectional pilot study in 25 participants (12 patients aged ≥ 70 years in an acute geriatric ward and 13 healthy volunteers aged 25–50 years), assessed by three raters. Muscle thickness measurement was estimated as the distance between the subcutaneous adipose tissue-muscle interface and muscle-bone interface of the radius at 30% proximal of the distance between the styloid process and distal insertion of the biceps brachii muscle of the dominant forearm. Examinations were repeated three times by each rater and intra- and inter-rater reliability was calculated. Feasibility analysis included consideration of technological, economic, legal, operational, and scheduling (TELOS) components.

Results

Mean muscle-thickness measurement difference between groups was 4.4 mm (95% confidence interval [CI] 2.4 mm to 6.3 mm], p < 0.001). Intra-rater reliability of muscle-thickness assessment was excellent, with intraclass correlation coefficient (ICC) of 0.947 (95%CI 0.902 to 0.974), 0.969 (95%CI 0.942 to 0.985), and 0.950 (95%CI 0.907 to 0.975) for observer A, B, and C, respectively. Inter-rater comparison showed good agreement (ICC of 0.873 [95%CI 0.73 to 0.94]). Four of the 17 TELOS components considered led to specific recommendations to improve the procedure’s feasibility in clinical practice.

Conclusion

Our findings suggest that US is a feasible tool to assess the thickness of the forearm muscles with good inter-rater and excellent intra-rater reliability in a sample of hospitalized geriatric patients, making it a promising option for use in clinical practice.

The Efficacy of a Brief Educational Training Session in Point-of-Care Pediatric Hip Ultrasound

BACKGROUND

Pediatric limp is a common presenting complaint to emergency departments. Despite this, diagnosis can be difficult in young patients with no history of trauma. Ultrasound can be used to identify a hip effusion, which may be the etiology of limp in pediatric patients. Brief educational training sessions have successfully been used to introduce novice ultrasound users to point-of-care (POC) ultrasound; however, the education of POC hip ultrasound is underexplored, and the efficacy of educational training sessions in this domain remains unknown.

OBJECTIVE

To evaluate the feasibility and efficacy of using a brief educational training session to teach novice ultrasound users to identify hip anatomy and effusions.

METHODS

Medical and physician assistant students were enrolled during an ultrasound education conference. A pretest evaluated prior knowledge, experience, and confidence level regarding POC hip ultrasound. Students attended a brief didactic session and then completed an objective structured assessment of technical skill as well as a posttest.

RESULTS

Twenty-eight students naive to hip ultrasound participated in this study. Levels of training included medical and physician assistant students. Mean test scores increased from the pretest (4.8 of 9, SD = 1.6) to the posttest (7.9 of 9, SD = 0.72) (P < 0.001). Average objective structured assessment of technical skill was 4.6 of 5 (SD, 0.75; 95% confidence interval, 4.3-4.9). After the sessions, confidence levels in identifying landmarks, joint space, and a joint effusion significantly increased (P < 0.001).

CONCLUSIONS

Pediatric hip ultrasound knowledge, performance, skills, and confidence improved as demonstrated by novice ultrasound users after a brief educational training session. Our study shows that a brief, targeted educational intervention was a feasible and effective method of introducing pediatric POC hip ultrasound to novices.

Development of colonic transit time and ultrasound imaging tools as objective indicators for assessing abnormal defecation associated with food intake: a narrative review based on previous scientific knowledge

Background

Functional gastrointestinal disorders (FGIDs) involve chronic or persistent gastrointestinal symptoms. Laboratory tests show no organic lesions, and the symptoms are due to dysfunction. The most typical FGID is irritable bowel syndrome (IBS). In IBS patients, defecation disorders are common and have adverse effects on daily life. The proper evaluation and analysis of colonic transit are important for the management of defecation disorders in IBS patients. In addition, dietary intake and lifestyle affect colonic transit. An accurate assessment of such factors can guide management, leading to improvements in colonic transit and the resolution of defecation disorders.

Main topic

The Rome IV diagnostic criteria for IBS are based on subjective symptoms, which must be communicated and explained by the patient, limiting their application. Colonic transit time and ultrasonography are objective tools that can be used to diagnose IBS. In particular, previous studies used colonic transit to accurately distinguish between constipation and normal stool passage and to assess delayed gastrointestinal motility. Diet and lifestyle modifications can improve colonic transit and ameliorate bowel dysfunction.

Conclusion

Colonic transit can be improved by modifying lifestyle factors. Defecation disorders in IBS patients may be resolved by focusing on such factors. In the future, methods of visualizing defecation disorders due to impaired gastrointestinal motility and objective indicators of the associated abdominal symptoms need to be investigated.

Implementation and assessment of a pediatric point-of-care ultrasound training course in Japan: a pilot study

Purpose

The popularity of point-of-care ultrasound (POCUS) has led to the creation of educational guidelines for its use. In Japan, however, a comprehensive training course for POCUS use in pediatric emergency medicine has yet to be developed. The present study aimed to implement a pilot course for pediatric POCUS training in Japan and to compare participants’ self-efficacy level before and after the course.

Methods

A half-day training course in pediatric POCUS was implemented at a meeting of the Japan Society of Point-of-Care Ultrasound. A standardized training course, including pre-learning materials, live lectures, and hands-on sessions, was developed based on the US consensus educational guidelines. Physicians interested in pediatric POCUS were recruited for participation and completed a self-evaluation survey before and after the course to access their background, self-efficacy in performing selected ultrasound procedures before and after the course, and their overall satisfaction with the course.

Results

In total, 31 physicians participated. Of these, 25 completed the survey. Ten participants were in post-graduate year (PGY) 1–2, 13 were in PGY 3–5, and eight were in PGY 6 or higher. The post-training self-efficacy score was significantly higher than the pre-course assessment score (86.0 [standard deviation (SD): 19.2] vs. 35.6 [SD 17.6], p =  < 0.05, mean difference: 49.6 [95% confidence interval 39.6–61.2]). Furthermore, overall satisfaction with the course was high at 8.6 (SD 1.8).

Conclusion

The present study implemented a pilot training course in pediatric POCUS and found the participants’ self-efficacy level to be significantly higher after the course.

A point-of-care thoracic ultrasound protocol for hospital medical emergency teams (METUS) improves diagnostic accuracy

Background

Point-of-care ultrasound (POCUS) has proven itself in many clinical situations. Few data on the use of POCUS during Medical Emergency Team (MET) calls exist. In this study, we hypothesized that the use of POCUS would increase the number of correct diagnosis made by the MET and increase MET’s certainty.

Methods

Single-center prospective observational study on adult patients in need for MET assistance. Patients were included in blocks (weeks). During even weeks, the MET physician performed a clinical assessment and registered an initial diagnosis. Subsequently, the POCUS protocol was performed and a second diagnosis was registered (US+). During uneven weeks, no POCUS was performed (US−). A blinded expert reviewed the charts for a final diagnosis. The number of correct diagnoses was compared to the final diagnosis between both groups. Physician’s certainty, mortality and possible differences in first treatment were also evaluated.

Results

We included 100 patients: 52 in the US + and 48 in the US−  group. There were significantly more correct diagnoses in the US+ group compared to the US− group: 78 vs 51% (P  = 0.006). Certainty improved significantly with POCUS (P  <  0.001). No differences in 28-day mortality and first treatment were found.

Conclusions

The use of thoracic POCUS during MET calls leads to better diagnosis and increases certainty.

Retention of Point-of-Care Ultrasound Skills Among Practicing Physicians: Findings of the VA National POCUS Training Program

BACKGROUND

Point-of-care ultrasound (POCUS) use continues to increase in many specialties, but lack of POCUS training is a known barrier among practicing physicians. Many physicians are obtaining POCUS training through postgraduate courses, but the impact of these courses on skill retention and frequency of POCUS use post-course is unknown. The purpose of this study was to assess the change in POCUS knowledge, skills, and frequency of use after 6-9 months of participating in a brief training course.

METHODS

Course participants' POCUS knowledge and hands-on technical skills were tested pre-course using an online, 30-question knowledge test and a directly observed skills test, respectively. The same knowledge and skills tests were repeated immediately post-course and after 6-9 months using remote tele-ultrasound software. Course participants completed a survey on their POCUS use pre-course and after 6-9 months post-course.

RESULTS

There were 127 providers who completed the POCUS training course from October 2016 to November 2017. Knowledge test scores increased from a median of 60% to 90% immediately post-course followed by a slight decrease to 87% after 8 months post-course. Median skills test scores for 4 common POCUS applications (heart, lung, abdomen, vascular access) increased 36-74 points from pre-course to immediately post-course with a 2-7-point decrease after 8 months. Providers reported more frequent POCUS use post-course, which suggests application of their POCUS knowledge and skills in clinical practice. More frequent use of cardiac POCUS applications was associated with significantly greater retention of cardiac skills at 8 months.

CONCLUSIONS

Practicing physicians can retain POCUS knowledge and hands-on skills 8 months after participating in a 2.5-day POCUS training course, regardless of frequency of POCUS use post-course.

American Society of Regional Anesthesia and Pain Medicine expert panel recommendations on point-of-care ultrasound education and training for regional anesthesiologists and pain physicians-part II: recommendations

Point-of-care ultrasound (POCUS) is a critical skill for all regional anesthesiologists and pain physicians to help diagnose relevant complications related to routine practice and guide perioperative management. In an effort to inform the regional anesthesia and pain community as well as address a need for structured education and training, the American Society of Regional Anesthesia and Pain Medicine Society (ASRA) commissioned this narrative review to provide recommendations for POCUS. The recommendations were written by content and educational experts and were approved by the guidelines committee and the Board of Directors of the ASRA. In part II of this two-part series, learning goals and objectives were identified and outlined for achieving competency in the use of POCUS, specifically, airway ultrasound, lung ultrasound, gastric ultrasound, the focus assessment with sonography for trauma exam, and focused cardiac ultrasound, in the perioperative and chronic pain setting. It also discusses barriers to POCUS education and training and proposes a list of educational resources. For each POCUS section, learning goals and specific skills were presented in the Indication, Acquisition, Interpretation, and Medical decision-making framework.

Point-of-Care Ultrasound, the New Musculoskeletal Physical Examination

ABSTRACT

The availability of handheld ultrasound offers physicians an opportunity to better define anatomy and pathophysiology, thus enhancing the diagnostic capabilities of a standard physical examination. The medical community increasingly embraces the potential for point-of-care ultrasound across medical specialties. The primary aim of this review was to identify and compile information on the current clinical utility of point-of-care ultrasound for musculoskeletal examination. This information will enable health care providers to understand the current utility and potential of musculoskeletal point-of-care ultrasound, thus facilitating its appropriate adoption into clinical practice.

Assessment of a Hands-On Seminar on Gastrointestinal Ultrasound

Transabdominal gastrointestinal (GI) ultrasound (US), despite its utility, is not a common procedure and underappreciated owing to its difficulty to perform. This study aimed to disseminate the skills of GIUS and assess the impact of our hands-on seminar. We annually held a half-day, hands-on seminar on GIUS at University of Toyama Hospital for physicians and sonographers from 2015 to 2017. Two months after the seminar, we inquired about clinical attainment by questionnaire. Out of 55 participants, 46 (83.6%) returned their questionnaires. Twenty participants (43.5%) reported that they had successfully diagnosed at least one GI disorder via GIUS since the seminar. Residual analyses stratified by the participants’ background showed that the novices, those having < 2 years’ experience in performing abdominal US, or no prior knowledge of GIUS, had significantly lower attainment rates (23.5% and 12.5%, respectively) than the others. Participants with 2 to 5 years’ experience in performing abdominal US or with some knowledge of GIUS had much higher rates of diagnosing GI disorders (54.5% and 57.9%, respectively). Nearly half of the participants had identified GI disorders using GIUS in 2 months following the training. The hands-on seminar was beneficial in disseminating these skills among a wide range of US operators.

A comparison between the effectiveness of a gamified approach with the conventional approach in point-of-care ultrasonographic training

BACKGROUND

Although gamification increases user engagement, its effectiveness in point-of-care ultrasonographic training has yet to be fully established. This study was conducted with the primary outcome of evaluating its effectiveness in point-of-care ultrasonographic training as compared to conventional approach.

METHODS

Participants consisting of junior doctors were randomized into either the (1) gamified or the (2) conventional educational approach for ultrasonographic training.

RESULTS

A total of 31 junior doctors participated in this study (16 participants in gamified arm, 15 in the conventional arm after one participant from the conventional arm dropped out due to work commitment). Two-way mixed ANOVA test showed that there was no statistically significant interaction between the types of educational approach and time of testing (pre-test, post-test, 2 months post-training) for both theoretical knowledge score and practical skills score, with F(2, 58) = 39.6, p < 0.001, partial η² = 0.4 and F(2, 58) = 3.06, p = 0.06, partial η² = 0.095, respectively. For theoretical knowledge score, pairwise comparisons showed that the mean 2 months post-training scores (20.28 +/- 0.70, 95% CI 18.87-21.69) and mean post-test scores (20.27 +/- 0.65, 95% CI 18.94-21.60) were better than the pre-test scores (12.99 +/- 0.50, 95% CI 11.97-14.00) with p-values < 0.001 for both comparisons respectively. Similarly, for practical skill score, pairwise comparisons showed that the mean 2 months post-training scores (20.28 +/- 0.70, 95% CI 18.87-21.69) and mean post-test scores (20.27 +/- 0.65, 95% CI 18.94-21.60) were also better than the pre-test scores (12.99 +/- 0.50, 95% CI 11.97-14.00) with p-values < 0.001 for both comparisons respectively. Participants in the gamification arm generally perceived the various game elements and game mechanics as useful in contributing and motivating them to learn ultrasonography.

CONCLUSIONS

Gamification approach could be an effective alternative to conventional approach in point-of-care ultrasonographic training.

Effectiveness of High-Fidelity Simulation in Training Emergency Medicine Physicians in Point of Care Ultrasonography in Pakistan: A Quasi-Experimental Study

Background Point-of-care ultrasound (PoCUS) is frequently utilized in emergency medicine (EM), with an extended-focused assessment with sonography in trauma (e-FAST) being the most widely used PoCUS modality. This modality is not only time- and cost-efficient, but it is highly accurate in the diagnosis and management of surgical patients in the emergency department, as well as being highly predictive of patient outcomes. Targeted training is essential to ensure a learner's confidence in image acquisition, interpretation, and translation of knowledge to making clinical decisions. High-fidelity simulation offers a uniquely safe and "mistake-forgiving" environment to teach and train medical professionals. The present study evaluated the effectiveness of a high-fidelity simulator to train EM physicians in e-FAST at a tertiary care teaching hospital in a lower-middle-income country. Methods This quasi-experimental study was performed at a state-of-the-art simulation center of a multidisciplinary university hospital in Karachi, Pakistan. Subjects were included if they were EM physicians who volunteered to participate and were available for the entire training and testing period. The educational intervention included lectures and hands-on practice on a high-fidelity simulator (SonoSim, Santa Monica, CA). Knowledge and image interpretation on e-FAST were evaluated using a questionnaire, administered before and after the training course. Each participant's ability to acquire and interpret satisfactory images was assessed by experienced EM physicians and recorded. Participants were also administered a needs assessment survey and a course evaluation. Data were analyzed using IBM SPSS Statistics for Windows, Version 20.0 (Armonk, NY: IBM Corp.). All the tests were two-sided, and p-values ≤0.05 were considered significant. Baseline characteristics and outcome variables were recorded and compared by Wilcoxon signed-rank tests. Results A total of 31 EM physicians, 12 (38.7%) men and 19 (61.3%) women, were enrolled in the study, with 24 (77.3%) having one to three years of EM experience. Mean and percentage group performance improved from 6 and 40% before the intervention to 14.5 and 96.6% after the intervention (Z=4.867, p≤0.05). Most improvement in image acquisition on high-fidelity simulation was observed in the upper right quadrant of the suprapubic window (29/31; 93.5%), followed by the upper left quadrant (27/31; 87%) and the subxiphoid window (21/31; 67%). All 31 participants reported improvements in comfort and confidence level with PoCUS after attending the workshop. Conclusions EM physicians who attended a brief workshop incorporating simulation demonstrated improvements in knowledge and image acquisition skills in all domains tested. High-fidelity simulation training is an effective modality for training EM physicians in e-FAST.

Standardized adult-gerontology acute care nurse practitioner point-of-care ultrasound training: A new perspective in the age of a pandemic

Our health care landscape is rapidly changing. With the aging population and seemingly increasing outbreak of communicable diseases, it is expected that there will be a continued demand for inpatient/critical care providers. The current COVID-19 pandemic provides a glimpse of a health care system in severe provider shortage. Adult-gerontology acute nurse practitioners (GACNPs) can play a vital part in relieving that shortage. But with the increased role, there is an increased responsibility and need for expansion of AGACNP skill set. This includes the training and utilization of point-of-care ultrasound (POCUS). The case reports and data available from countries that have already combated COVID-19 outbreak show POCUS can play a key part in managing critically ill patients on isolation precautions. This article provides my perspective on POCUS training and competency achievement for AGACNPPs.

Impact of a 4-hour Introductory eFAST Training Intervention Among Ultrasound-Naïve U.S. Military Medics

INTRODUCTION

Advances in the portability of ultrasound have allowed it to be increasingly employed at the point of care in austere settings. Battlefield constraints often limit the availability of medical officers throughout the operational environment, leading to increased interest in whether highly portable ultrasound devices can be employed by military medics to enhance their provision of combat casualty care. Data evaluating optimal training for effective medic employment of ultrasound is limited however. This prospective observational cohort study's primary objective was to assess the impact of a 4-hour introductory training intervention on ultrasound-naïve military medic participants' knowledge/performance of the eFAST application.

MATERIALS AND METHODS

Conventional U.S. Army Medics, all naïve to ultrasound, were recruited from across JBLM. Volunteer participants underwent baseline eFAST knowledge assessment via a 50-question multiple-choice exam. Participants were then randomized to receive either conventional, expert-led classroom didactic training or didactic training via an online, asynchronously available platform. All participants then underwent expert-led, small group hands-on training and practice. Participants' eFAST performance was then assessed with both live and phantom models, followed by a post-course knowledge exam. Concurrently, emergency medicine (EM) resident physician volunteers, serving as standard criterion for trained personnel, underwent the same OSCE assessments, followed by a written exam to assess their baseline eFAST knowledge. Primary outcome measures included (1) post-course knowledge improvement, (2) eFAST exam technical adequacy, and (3) eFAST exam OSCE score. Secondary outcome measures were time to exam completion and diagnostic accuracy rate for hemoperitoneum and hemopericardium. These outcome measures were then compared across medic cohorts and to those of the EM resident physician cohort.

RESULTS

A total of 34 medics completed the study. After 4 hours of ultrasound training, overall eFAST knowledge among the 34 medics improved from a baseline mean of 27% on the pretest to 83% post-test. For eFAST exam performance, the medics scored an average of 20.8 out of a maximum of 22 points on the OSCE. There were no statistically significant differences between the medics who received asynchronous learning versus traditional classroom-based learning, and the medics demonstrated comparable performance to previously trained EM resident physicians.

CONCLUSIONS

A 4-hour introductory eFAST training intervention can effectively train conventional military medics to perform the eFAST exam. Online, asynchronously available platforms may effectively mitigate some of the resource requirement burden associated with point-of-care ultrasound training. Future studies evaluating medic eFAST performance on real-world battlefield trauma patients are needed. Skill and knowledge retention must also be assessed for this degradable skill to determine frequency of refresher training when not regularly performed.

Frequency of Abnormalities Detected by Point-of-Care Lung Ultrasound in Symptomatic COVID-19 Patients: Systematic Review and Meta-Analysis

The COVID-19 pandemic has resulted in significant morbidity, mortality, and strained healthcare systems worldwide. Thus, a search for modalities that can expedite and improve the diagnosis and management of this entity is underway. Recent data suggested the utility of lung ultrasound (LUS) in the diagnosis of COVID-19 by detecting an interstitial pattern (B-pattern). Hence, we aimed to pool the proportion of various reported lung abnormalities detected by LUS in symptomatic COVID-19 patients. We conducted a systematic review (PubMed, MEDLINE, and EMBASE until April 25, 2020) and a proportion meta-analysis. We included seven studies examining the role of LUS in 122 COVID-19 patients. The pooled proportion (PP) of B-pattern detected by lung ultrasound (US) was 0.97 (95% CI: 0.94–1.00 I² 0%, Q 4.6). The PP of finding pleural line abnormalities was 0.70 (95% CI: 0.13–1.00 I² 96%, Q 103.9), of pleural thickening was 0.54 (95% 0.11–0.95 I² 93%, Q 61.1), of subpleural or pulmonary consolidation was 0.39 (95% CI: 0.21–0.58 I² 72%, Q 17.8), and of pleural effusion was 0.14 (95% CI: 0.00–0.37 I² 93%, Q 27.3). Our meta-analysis revealed that almost all SARS-CoV-2–infected patients have abnormal lung US. The most common abnormality is interstitial involvement depicted as B-pattern. The finding from our review highlights the potential role of this modality in the triage, diagnosis, and follow-up of COVID-19 patients. A sizable diagnostic accuracy study comparing LUS, computed tomography scan, and COVID-19–specific tests is warranted to further test this finding and to delineate the diagnostic and prognostic yield of each of these modalities.

Efficacy of an education program for nurses that concerns the use of point-of-care ultrasound to monitor for aspiration and pharyngeal post-swallow residue: A prospective, descriptive study

BACKGROUND

For nurses to provide swallowing care that is appropriate to individual patients' swallowing functions, techniques for using ultrasound to monitor for aspiration and pharyngeal post-swallow residue would be helpful.

OBJECTIVES

This study seeks to clarify the effectiveness of an education program concerning the use of ultrasound to assess swallowing function (the "Swallowing Point-of-Care Ultrasound Education Program"). This assessment is based on a comparison of the observation skills of general nurses' and certified nurses in dysphagia nursing in this regard; both groups underwent the education program, but dysphagia nurses have greater knowledge of swallowing functions as a result of their training.

METHODS

This prospective descriptive study was conducted as a post-graduate education program in two locations in Japan. The swallowing point-of-care ultrasound education program comprised four elements: e-learning, practical seminar, self-learning, and objective structured clinical examination. The objective structured clinical examination was used after the program to assess whether the participants had obtained the necessary skills. The general nurses were then asked to report the ease-of-use of the education materials.

RESULTS

Of the 32 participants enrolled in the program, 22 general nurses and nine dysphagia nurses completed the program. In the objective structured clinical examination concerning monitoring for aspiration, the dysphagia-nurses group had a higher proportion of participants evaluated as "excellent" (p = 0.007); this group had a significantly higher ability to maintain adequate images during the swallowing process than did the general-nurse group (p = 0.034). However, there was no difference between the two groups regarding monitoring for post-swallowing residue. Further, over 70% of the nurses gave a positive evaluation of the user-friendliness of the e-learning and practical seminar.

CONCLUSIONS

Our results suggest that the swallowing point-of-care ultrasound education program provides both general nurses and dysphagia nurses with sufficient knowledge and skill to monitor for aspiration and post-swallowing residue.

Use of a Refresher Course Increases Confidence in Point-of-Care Ultrasound Skills in Emergency Medicine Faculty

Introduction All practicing emergency medicine (EM) physicians need to maintain a skillset in emergency ultrasound (US) after their initial training. EM physicians in academic practice may be supervising trainees performing ultrasound applications that they aren't comfortable with. This study investigates the effectiveness of a US refresher course. The hypothesis was that a series of short courses would increase confidence in performing and supervising US applications. Methods Nine basic emergency ultrasound applications were taught over the course of one year by ultrasound fellowship-trained EM faculty in a simulation center at a single academic institution. Each session included 30-minutes of didactics/image review and 30-minutes of hands-on practice on normal volunteers and was followed by an anonymous questionnaire evaluating comfort level performing and supervising the ultrasound application before and after the course using a Likert scale from 1 "not at all confident" to 5 "very confident". Results Thirty-six of 60 EM physicians participated in at least 1 of the 9 sessions (median 3, interquartile range 2-4). Faculty who attended had a median of 10 (interquartile range 7-15) years in practice and 61% work at both academic and community sites. For all sessions combined, confidence in performing US increased from a mean score on the Likert scale of 3.3 to 4.4 (difference 1.1, confidence interval (CI) (0.94, 1.29), p < 0.001) and confidence in supervising trainees increased from a mean of 3.4 to 4.5 (difference 1.1, CI (0.88, 1.23), p < 0.001). The largest increases were seen in musculoskeletal (MSK), nerve, and pelvic applications and the least increase was seen with the session focused on intravenous access, but confidence was increased in all sessions. Physicians in practice ≥10 years increased in confidence in performing and supervising the applications by 1.4 (CI (1.11, 1.60), p < 0.001) and 1.3, (CI (1.01, 1.49), p < 0.001), respectively. Physicians in practice <10 years increased 0.8 (CI (0.57, 1.03), p < 0.001) and 0.8 (CI (0.55, 1.05), p < 0.001), respectively. Conclusion An emergency ultrasound refresher course for EM physicians at a single institution improved self-reported confidence in both performing and supervising trainees in all applications reviewed. Those in practice ≥10 years showed the largest increases.

Lessons Learned from a Study of the Integration of a Point-of-Care Ultrasound Course into the Undergraduate Medical School Curriculum

Background

Point-of-care ultrasound (POCUS) diagnosis, performed by a physician at the patient bedside, is routinely used in emergency medicine and critical care. Although training in ultrasonography has become part of the medical school curriculum, POCUS can be challenging for medical students. This study aimed to assess the effectiveness of a one-day POCUS course in a group of final-year medical students by pre-course and post-course assessment of both diagnostic ability and changes in student confidence levels in making a diagnosis.

Material/Methods

A prospective study recruited 57 final-year medical students who participated in a one-day POCUS course. Improvement in making decisions and levels of confidence were evaluated before and two weeks after the course, using image-based testing and a self- evaluation questionnaire.

Results

All 57 final-year medical students attended the course and completed the tests and surveys. The pre-training and post-training test scores of medical students improved from 41.78±12% to 58±13%. Student confidence scores in the post-training assessment significantly increased. The post-training confidence scores were significantly increased compared with the pre-training scores regardless of whether or not the questions were answered correctly (p<0.001). The Dunning-Kruger effect, or cognitive bias, might partially explain this phenomenon.

Conclusions

One day of POCUS training integrated into anesthesia curriculum for final-year medical students improved performance in the post-training test scores and improved their confidence scores. Further studies are needed to evaluate this effect and to develop adequate tools to assess medical students.

Internal medicine residents' point-of-care ultrasound skills and need assessment and the role of medical school training

Introduction: Point-of-care-ultrasound (POCUS) as a useful bedside tool is growing. Few studies have examined residents' attitude towards POCUS or compared POCUS image interpretation skills between residents with and without POCUS training in medical school. Material and Methods: We distributed an anonymous survey and image interpretation test to assess residents' attitude towards POCUS, confidence, and skills in interpreting POCUS images and videos. Using independent samples t-tests, we compared mean confidence levels and test scores between residents with and without prior POCUS training. Results: Fifty-two residents responded to survey (response rate 68%) and 59 took the image interpretation test (77%). Most residents (90%) reported being interested in POCUS. Residents with prior POCUS training (n=13) were either PGY-1 (9) or PGY-2 (4). No PGY-3 resident had prior training. Most residents (83%) thought POCUS could be extremely useful in the inpatient setting compared to 29% for outpatient setting. PGY-1 residents with prior training had a higher mean confidence level than PGY-1 residents without prior training, but the difference was not statistically significant (3.26 vs 2.64; p=0.08). PGY-1 with prior training had a mean confidence level that was close to that of PGY-3 residents. PGY-1 residents with prior training scored significantly higher than PGY-1 residents without prior training in image interpretation test (10.25 vs 7; p=0.01). Residents felt most confident in interpreting inferior vena cava images (mean 3.7; max. 5), which also had the highest score in image interpretation test (correct response rate of 88%). Conclusion: Our residents seem very interested in POCUS. PGY-1 residents with prior POCUS training in medical school seem to have higher confidence in their POCUS skills than PGY-1 residents without prior training and outperformed them in image interpretation test. The study is very instructive in building our future POCUS curriculum for residents.
