Utility of Handheld Ultrasound Performed by Cardiology Fellows in Patients Presenting with Suspected ST-Elevation Myocardial Infarction. J Cardiovasc Echogr 2022; 32:205-211. [PMID: 36994123 PMCID: PMC10041406 DOI: 10.4103/jcecho.jcecho_51_22] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2022] [Revised: 09/06/2022] [Accepted: 10/02/2022] [Indexed: 03/31/2023] Open
Abstract
Background In academic hospitals, cardiology fellows may be the first point of contact for patients presenting with suspected ST-elevation myocardial infarction (STEMI) or acute coronary syndrome (ACS). In this study, we sought to determine the role of handheld ultrasound (HHU) in patients with suspected acute myocardial injury (AMI) when used by fellows in training, its association with the year of training in cardiology fellowship, and its influence on clinical care. Methods This prospective study's sample population comprised patients who presented to the Loma Linda University Medical Center Emergency Department with suspected acute STEMI. On-call cardiology fellows performed bedside cardiac HHU at the time of AMI activation. All patients subsequently underwent standard transthoracic echocardiography (TTE). The impact of the detection of wall motion abnormalities (WMAs) on HHU in regard to clinical decision-making, including whether the patient would undergo urgent invasive angiography, was also evaluated. Results Eighty-two patients (mean age: 65 years, 70% male) were included. The use of HHU by cardiology fellows resulted in a concordance correlation coefficient of 0.71 (95% confidence interval: 0.58-0.81) between HHU and TTE for left ventricular ejection fraction (LVEF), and a concordance correlation coefficient of 0.76 (0.65-0.84) for wall motion score index. Patients with WMA on HHU were more likely to undergo invasive angiogram during hospitalization (96% vs. 75%, P < 0.01). The time interval between the performance of HHU to initiation of cardiac catheterization (time-to-cath) was shorter in patients with abnormal versus normal HHU examinations (58 ± 32 min vs. 218 ± 388 min, P = 0.06). Finally, among patients who underwent angiography, those with WMA were more likely to undergo angiography within 90 min of presentation (96% vs. 66%, P < 0.001). Conclusion HHU can be reliably used by cardiology fellows in training for measurement of LVEF and assessment of wall motion abnormalities, with good correlation to findings obtained via standard TTE. HHU-identified WMA at first contact was associated with higher rates of angiography as well as sooner angiography compared to patients without WMA.

Abstract
PURPOSE Point-of-care ultrasound (POCUS) facilitates diagnostic, procedural, and resuscitative applications in anesthesiology. Structured POCUS curricula improve learner satisfaction, test scores, and clinical management, but the learning curve towards competency and retention of skills over time remain unknown. METHODS We conducted a prospective observational study to determine when anesthesiology trainees enrolled in a POCUS curriculum achieve competency in POCUS skills. We also investigated the learning curve of trainees' competency using a POCUS-specific competency-based medical education assessment. The structured, longitudinal POCUS curriculum included online lectures, journal articles, live model scanning sessions, video review of cases, and a portfolio of supervised scans. Point-of-care ultrasound scanning sessions on standardized patients were conducted in the simulation lab for 2.5 hr a week and each resident completed eight sessions (20 hr) per academic year. At each scanning session, timed image acquisition scores were collected and POCUS skills entrustment scale evaluations were conducted. The primary outcome was the number of supervised scans and sessions required to achieve a mean entrustment score of 4 ("may use independently"). Secondary outcomes included image acquisition scores and retention of skills after six months. RESULTS The mean (standard deviation) number of supervised scans required for trainees (n = 29) to reach a mean entrustment score of ≥ 4 was 36 (10) scans over nine sessions for rescue echo. A mean entrustment score of ≥ 4 was observed for lung ultrasound after a mean (SD) of 8 (3) scans over two sessions. CONCLUSIONS Our study shows that anesthesiology residents can achieve competence in rescue echo and lung ultrasound through participation in a structured, longitudinal POCUS curriculum, and outlines the learning curve for progression towards competency.

Abstract
Background Cardiac point of care ultrasound (POCUS) is increasingly utilized by trainees across various specialties and can rapidly assess the cardiac status of unstable patients. However, the quality of trainee performed cardiac examinations has been reported only in controlled studies. In this study we aimed to assess the quality of all cardiac POCUS performed by internal medicine trainees at a major academic medical center over a three-year period. Methods 256 studies were included and were graded by experts blinded to postgraduate year (PGY) using a previously validated scoring metric. Results We found significant improvement in overall quality of resident performed cardiac POCUS from PGY 1 to 3 (10.8, 10.2, 13.2, p = 0.012). Assessment of left ventricular function was possible in 82% of studies and increased from PGY 1 to PGY 3 (77%, 76%, 88%, p = 0.025). Similar trends were seen in the assessment of the pericardial space (67%, 71%, 84%, p = 0.012). Images sufficient for right ventricular and volume status assessment were less commonly found (65%, 60%, 75% and 60%, 49%, 57%, respectively). Conclusions This study provides a real world experience of the level of diagnostic accuracy that can be expected from IM trainees with minimal hands-on supervision.

Motivations, barriers, and professional engagement: a multisite qualitative study of internal medicine faculty's experiences learning and teaching point-of-care ultrasound. BMC MEDICAL EDUCATION 2022; 22:171. [PMID: 35279153 PMCID: PMC8918294 DOI: 10.1186/s12909-022-03225-w] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/20/2021] [Accepted: 02/28/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND Point-of-care ultrasound (POCUS) graduate medical education is expanding across many specialties, but a lack of trained faculty is a common barrier. Even well-designed faculty development programs struggle with retention, yet little is known about the experiences of practicing physicians learning POCUS. Our objective is to explore the experiences of clinician-educators as they integrate POCUS into their clinical and teaching practices to help inform curriculum design. METHODS Qualitative study using instrumental case study design to analyze interview data from 18 internal medicine clinician-educators at 3 academic health centers. Interviewees were recruited by program directors at each site to include participants with a range of POCUS use patterns. Interviews took place from July-August 2019. RESULTS Analysis yielded 6 themes: teaching performance, patient care, curriculum needs, workflow and access, administrative support, and professional engagement. Participants felt POCUS enhanced their teaching skills, clinical decision making, and engagement with patients. The themes highlighted the importance of longitudinal supervision and feedback, streamlined integration of POCUS into clinical workflow, and administrative support of time and resources. Interviewees reported learning and teaching POCUS helped combat burn-out and enhance their sense of professional engagement. CONCLUSIONS Learning POCUS as a practicing clinician-educator is a complicated endeavor that must take into account mastery of psychomotor skills, existing practice habits, and local institutional concerns. Based upon the themes generated from this study, we make recommendations to help guide POCUS faculty development curriculum design. Although this study focused on internists, the findings are likely generalizable to other specialties with growing interest in POCUS education.

Abstract
As point-of-care ultrasound (POCUS) becomes more integrated into clinical practice, it is essential to address all aspects of ultrasound operator proficiency. Ultrasound proficiency requires the ability to acquire, interpret and integrate bedside ultrasound images. The difference in image acquisition psychomotor skills between novice (trainee) and expert (instructor) ultrasonographer has not been described. We created an inexpensive system, called Probe Watch, to record probe motion and assess image acquisition in cardiac POCUS using an inertial measurement device and software for data recording based on open-source components. We designed a temporal convolutional network for skills classification from probe motion that integrates clinical domain knowledge. We further designed data augmentation methods to improve its generalization. Subsequently, we validated the setup and assessment method on a set of novice and expert sonographers performing cardiac ultrasound in a simulation-based training environment. The proposed methods classified participants as novice or expert with areas under the receiver operating characteristic curve of 0.931 and 0.761 for snippets and trials, respectively. Integrating domain knowledge into the neural network had added value. Furthermore, we identified the most discriminative features for assessment. Probe Watch quantifies motion during cardiac ultrasound and provides insight into probe motion behavior. It may be deployed during cardiac ultrasound training to monitor learning curves objectively and automatically.

Abstract
Background: Focused cardiac ultrasound (FCU) is a safe and efficient diagnostic intervention for internal medicine physicians. FCU is a highly teachable skill, but is used in routine cardiac assessment in only 20% of surveyed training programs.We developed an FCU curriculum for internal medicine residents and an assessment tool to evaluate the impact of the curriculum on trainee knowledge and confidence. Methods: Internal medicine residents rotating through clinical cardiology services underwent 30 minutes of didactic and 60 minutes of hands-on teaching on acquisition and interpretation of FCU. A 20 item pre and post-curriculum online survey was administered (November 2018-December 2019) to assess confidence and knowledge in FCU. Results: 79 of 116 (68%) residents completed the pre-survey and 50 completed the post-survey, of whom 34 received the curriculum. The mean change in confidence score in those who received versus did not receive the curriculum was 0.99 versus 0.39 (p=0.046) on a 5-point Likert scale. Among 33 residents who had paired pre- and post-surveys the mean change in confidence score was 1.2 versus 0.85 (p<0.001) in those who received versus did not receive the curriculum. The mean increase in knowledge score was 13% versus 7% respectively (p<0.0001). Conclusions: We instituted a novel curriculum for internal medicine residents to gain experience in image acquisition and interpretation. Both confidence and knowledge in FCU improved following the curriculum, indicating that this is a highly teachable skill. Additional analysis of the of the FCU study images will be useful for informing future interventions.

Abstract
BACKGROUND Focused cardiac ultrasound (FoCUS) is a valuable skill for rapid assessment of cardiac function and volume status. Despite recent widespread adoption among physicians, there is limited data on the optimal training methods for teaching FoCUS and metrics for determining competency. We conducted a systematic review to gain insight on the optimal training strategies, including type and duration, that would allow physicians to achieve basic competency in FoCUS. METHODS Embase, PubMed, and Cochrane Library databases were searched from inception to June 2020. Included studies described standardized training programs for at least 5 medical students or physicians on adult FoCUS, followed by an assessment of competency relative to an expert. Data were extracted, and bias was assessed for each study. RESULTS Data were extracted from 23 studies on 292 learners. Existing FoCUS training programs remain varied in duration and type of training. Learners achieved near perfect agreement (κ > 0.8) with expert echocardiographers on detecting left ventricular systolic dysfunction and pericardial effusion with 6 h each of didactics and hands-on training. Substantial agreement (κ > 0.6) on could be achieved in half this time. CONCLUSION A short training program will allow most learners to achieve competency in detecting left ventricular systolic dysfunction and pericardial effusion by FoCUS. Additional training is necessary to ensure skill retention, improve efficiency in image acquisition, and detect other pathologies.

Abstract
Background: Focused cardiac ultrasound (FCU) is widely used by healthcare providers to answer specific questions about cardiac structure and function at the bedside. Currently, no widely accepted FCU image acquisition checklist exists to assess learners with varying skill levels from different specialties. Objective: The primary objective of this project was to develop a consensus-based FCU image acquisition checklist using a multispecialty group of point-of-care ultrasound (POCUS) experts. Methods: The essential components of an FCU examination were identified on the basis of published recommendations from echocardiography and international ultrasound societies. A checklist of the essential components of an FCU examination was drafted. A panel of POCUS experts from different medical specialties in the United States and Canada was convened to vote on each checklist item by answering two questions: 1) Is this item important to include in a checklist of essential FCU skills applicable to any medical specialty? and 2) Should the learner be required to successfully complete this item to be considered competent? A modified Delphi approach was used to assess the level of agreement for each checklist item during four rounds of voting. Checklist items that achieved an agreement of 80% or greater were included in the final checklist. Results: Thirty-one POCUS experts from seven different medical specialties voted on sixty-five items to be included in the FCU image acquisition assessment tool. The majority of POCUS experts (61%) completed all four rounds of voting. During the first round of voting, 59 items reached consensus, and after revision and revoting, an additional 3 items achieved 80% or greater consensus. A total of 62 items were included in the final checklist, and 57 items reached consensus as a requirement for demonstration of competency. Conclusion: We have developed a multispecialty, consensus-based FCU image acquisition checklist that may be used to assess the skills of learners from different specialties. Future steps include studies to develop additional validity evidence for the use of the FCU assessment tool and to evaluate its utility for the translation of skills into clinical practice.
