Prevalence and Scope of Point-of-Care Ultrasound Education in Internal Medicine, Pediatric, and Medicine-Pediatric Residency Programs in the United States

Point-of-Care Ultrasound for the General Pediatric Resident: A Needs Assessment

Point-of-care ultrasound (POCUS) is a valuable tool in pediatric care, but formalized education on POCUS is not a standard part of pediatric residency. Our primary objective was to conduct a needs assessment to determine pediatric residents' attitudes toward ultrasound education. A Likert scale-based survey was distributed to residents at 48 pediatric residency programs. Respondents were asked to rate their agreement to statements about ultrasound education at their respective programs. Participants were also asked to rank ultrasound indications in order of importance. Ninety-seven survey responses were included in the final data set. Sixty percent of respondents had not performed any ultrasound scans during residency. Ninety-two percent of respondents indicated an interest in ultrasound training during residency and that they desired a formal POCUS curriculum. Eighty-one percent of residents indicated that having more ultrasound education would make their programs more attractive to applicants. Pediatric residents recognize the utility of POCUS and desire additional education during training.

Enhancing point-of-care ultrasound (POCUS) utilization in primary care: A thyroid POCUS training course for internal medicine residents

BACKGROUND

POCUS is valuable in primary care, yet outpatient-specific point-of-care ultrasound (POCUS) curriculum integration into internal medicine (IM) residency is limited. We addressed this gap by developing a thyroid POCUS workshop for IM residents.

AIM

Develop and implement an educational curriculum to integrate thyroid POCUS into an IM residency program and evaluate the impact on resident knowledge, perceived skills, and attitudes.

SETTING

The study was conducted in a resident primary care clinic at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell Residency Program in Internal Medicine at North Shore University Hospital and Long Island Jewish Medical Center.

PARTICIPANTS

All 108 IM residents (PGY1-3) in one program participated in the study during their ambulatory clinic block.

PROGRAM DESCRIPTION

Residents participated in a 1-hour workshop involving a didactic session and two breakout groups: one for hands-on practice and another for case-based discussions with image review.

PROGRAM EVALUATION

Residents completed pre- and post-session surveys assessing knowledge, perceived skills, and attitudes toward thyroid POCUS. These data showed statistically significant increases in all assessed areas.

DISCUSSION

Integrating thyroid POCUS into an IM residency curriculum significantly improved resident knowledge, attitudes, and perceived skills related to these exams. Residents valued this learning experience and expressed intentions to incorporate it into their future practice.

A shared point of care ultrasound curriculum for graduate medical education

BACKGROUND

Point of care ultrasound (POCUS) education has grown significantly over the past two decades. Like most curricular items, POCUS education is siloed within individual graduate medical education (GME) programs. The purpose of this study was to evaluate the effectiveness of a shared GME POCUS curriculum between five GME programs at a single institution.

METHODS

Post-graduate-year-1 (PGY-1) residents from emergency medicine (EM), family medicine (FM), internal medicine (IM), combined internal medicine-pediatrics (IM-Peds) and combined emergency medicine-pediatrics (EM-Peds) residency programs were enrolled in a core POCUS curriculum. The curriculum included eleven asynchronous online learning modules and ten hands-on training sessions proctored by sonographers and faculty physicians with POCUS expertise. Data was gathered about the curriculum's effectiveness including participation, pre- and post-curricular surveys, pre- and post-knowledge assessments, and an objective skills assessment.

RESULTS

Of the 85 residents enrolled, 61 (72%) participated in the curriculum. Engagement varied between programs, with attendance at hands-on sessions varying the most (EM 100%, EM-Peds 100%, FM 40%, IM 22%, Med-Peds 11%). Pre- and post-knowledge assessment scores improved for all components of the curriculum. Participants felt significantly more confident with image acquisition, anatomy recognition, interpreting images and incorporating POCUS findings into clinical practice (p < 0.001) after completing the curriculum.

CONCLUSION

In this shared GME POCUS curriculum, we found significant improvement in POCUS knowledge, attitudes, and psychomotor skills. This shared approach may be a viable way for other institutions to provide POCUS education broadly to their GME programs.

Facilitators, barriers, and changes in POCUS use: longitudinal follow-up after participation in a national point-of-care ultrasound training course in Japan

BACKGROUND

POCUS training courses are effective at improving knowledge and skills, but few studies have followed learners longitudinally post-course to understand facilitators, barriers, and changes in POCUS use in clinical practice. We conducted a prospective observational study of physicians who attended 11 standardized POCUS training courses between 2017 and 2019 in Japan. Physicians who attended a standardized POCUS course were surveyed about their current frequency of POCUS use of the heart, lung, abdomen, and lower extremity veins, and perceived barriers and facilitators to POCUS use in clinical practice.

RESULTS

Data were analyzed from 112 completed surveys (response rate = 20%). A majority of responding physicians were faculty (77%) in internal medicine (69%) affiliated with community hospitals (55%). The mean delay between course attendance and survey response was 50.3 months. A significant increase in POCUS use from < 1 to ≥ 1 time per week was seen for all organ systems after 50 months post-course (p < 0.01). Approximately half of course participants reported an increase in the frequency of cardiac (61%), lung (53%), vascular (44%), and abdominal (50%) ultrasound use. General facilitators of POCUS use were easy access to ultrasound machines (63%), having a colleague with whom to learn POCUS (47%), and adequate departmental support (46%). General barriers included lack of opportunities for POCUS training (47%), poor access to ultrasound machines (38%), and limited time for POCUS training (33%). In the group with increased POCUS usage, specific facilitators reported were enhanced POCUS knowledge, improved image acquisition skills, and greater self-confidence in performing POCUS. Conversely, the group without increased POCUS usage reported lack of supervising physicians, low confidence, and insufficient training opportunities as specific barriers.

CONCLUSIONS

Approximately half of physicians reported an increase in cardiac, lung, vascular, and abdominal POCUS use > 4 years after attending a POCUS training course. In addition to improving access to ultrasound machines and training opportunities, a supportive local clinical environment, including colleagues to share experiences in learning POCUS and local experts to supervise scanning, is important to foster ongoing POCUS practice and implementation into clinical practice.

Reliability of renal point-of-care ultrasound (POCUS) performed by pediatric postgraduates to diagnose hydronephrosis in infants

Purpose

Point-of-care ultrasound (POCUS) has gained prominence in a variety of medical specialties due to advances in ultrasound technology. POCUS has not been fully integrated into pediatric residency training programs despite its widespread use and proven benefits. At our institution, renal POCUS is performed by pediatric residents for the evaluation of hydronephrosis, which is the main pathology for which ultrasound is used in the clinical practice of pediatric nephrology. This study was conducted to evaluate the quality of renal POCUS performed by pediatric residents in infants.

Methods

Four pediatric residents, comprising two first-year and two second-year residents at Konyang University Hospital, participated in the study conducted from May 2021 to May 2022. All participants had completed our Point-of-Care Ultrasound (POCUS) training program. The study focused on infants admitted to the pediatric inpatient unit, identified by attending physicians as requiring renal ultrasound. All infants underwent their initial kidney ultrasound examination. Temporal alignment between renal Point-of-Care Ultrasound (POCUS) performed by pediatric residents and conventional ultrasound (USG) conducted by radiologists was asynchronous. Pediatric residents conducted POCUS sessions during scheduled radiologist appointments throughout the day, occurring either before or after the radiologist's examination. There was no mutual awareness of each other's results. Inter-observer agreement between radiologists and pediatric residents was compared for the presence or absence of hydronephrosis and its grade, which are primary considerations in pediatric renal ultrasound.

Results

Our study found that 53 infants (68.8%) were diagnosed with hydronephrosis using point-of-care ultrasound (POCUS), compared to 48 infants (62.3%) diagnosed with conventional ultrasound (USG). Among the POCUS examinations conducted by pediatric residents, hydronephrosis of SFU grades 1, 2, 3, and 4 were observed in 56.6%, 35.8%, 7.5%, and 0%, respectively. Inter-observer reliability between POCUS and conventional USG showed good agreement, with Cohen's kappa coefficients exceeding 0.8 for sensitivity and 0.6 for grading.

Conclusions

Renal POCUS performed well in diagnosing and grading hydronephrosis in infants when performed by pediatric residents who had completed a two-phase training program.

Confidence and Utilization are Poorly Associated with Point-of-Care Ultrasound Competency among Internal Medicine Trainees

INTRODUCTION

Point-of-Care Ultrasound (POCUS) is the utilization of bedside ultrasound by clinicians. Its portable and rapid diagnostic capabilities make it an excellent tool for deployment and mobile military settings. However, formal and uniform POCUS training is lacking. Furthermore, the evaluation of these curricula often relies on confidence assessment. Our objective was to assess the relationships between confidence, frequency of utilization, and image interpretation knowledge among our Internal Medicine residents before and after the implementation of a formal curriculum.

MATERIALS AND METHODS

In November 2020, we implemented a longitudinal, flipped-classroom, academic half-day curriculum, conducting a prospective before-after cohort evaluation of its implementation. The POCUS curriculum was implemented as a longitudinal, asynchronous, flipped-classroom activity with workshop sessions during one academic half-day per month. We measured confidence via a Likert scale and utilization frequency via a five-point scale. Six multiple-choice questions (MCQ) with ultrasound videos assessed image interpretation competency. The image interpretation score was reported as percent correct. We related confidence and utilization to the image interpretation score.

RESULTS

Ninety-nine residents were eligible for participation. Fifty-four (55%) completed a pre-curriculum assessment and 45 (45%) completed a post-curriculum assessment. Average image interpretation scores were 41% pre-curriculum and 51% post-curriculum (P =0.02). Pre-curriculum residents were on average unconfident (mean=2.56), and post-curriculum residents were on average confident (mean=3.62). Pre-curriculum residents used POCUS occasionally (mean=2.02, count 13 (24%) never utilizing). Post-curriculum residents used POCUS occasionally (mean=2.42, count 4 (9%) never utilizing). Pre- and post-curriculum confidence were not significantly associated with image interpretation scores (pre-curriculum: r=-0.10, P =0.50; post-curriculum: r=0.24, P =0.11). Pre- and post-curriculum utilization were not significantly associated with image interpretation scores (pre-curriculum: r=0.15, P =0.28; post-curriculum: r=0.02, P =0.90). The number of curriculum sessions attended was significantly associated with higher image interpretation scores (r=0.30, P =0.003).

CONCLUSIONS

Our study suggests that POCUS confidence and informal utilization do not correlate with image interpretation knowledge on MCQs among Internal Medicine residents. These findings support assessing direct measures of knowledge, rather than confidence, as an endpoint in evaluating POCUS curricula among Internal Medicine residents.

Recommendations for Ultrasound Guidance for Diagnostic Nerve Blocks for Spasticity. What Are the Benefits?

The diagnostic nerve block (DNB) for spasticity is the percutaneous application of an anesthetic to an individual peripheral nerve trunk (mixed motor sensory nerve), nerve branch to a muscle or an intramuscular branch. The DNB causes a temporary paralysis to assess the contribution of muscle(s) on the spastic pattern and may unmask a fully or partially increased joint range of motion. The anesthetic literature supports the use of ultrasound (US) guidance to improve nerve blocks for sensory targets. This communication summarizes the potential advantages that support the use of US to improve DNB technique. Nerves are much smaller than muscle targets and have various known innervation patterns. US allows for rapid localization of the target before injection, particularly in complex anatomy patterns. The nerve trunks are typically found adjacent to or encapsulating blood vessels, which can be quickly identified with or without color Doppler, allowing the clinician to scan from the vessels to the target and avoid intravascular injection. Lower stimulation levels can be used as the targeted muscle(s) can be seen stimulating rather than only on the surface. A shorter needle insertion time and lower stimulation levels should cause less discomfort to the patient. Smaller volumes of anesthetic may be used as the fluid is seen reaching its target and cessation of stimulation is observed. Further study is needed to identify evidence supporting US utilization with electrical stimulation in DNBs for spasticity management, as US use during nerve blocks for perineurial anesthesia has demonstrated improved patient safety and procedural efficiency.

Two Affordable, High-Fidelity Central Venous Models for Ultrasound-Guided Interventional Training

INTRODUCTION

Ultrasound-guided vascular access is an increasingly popular technique due to its reduced complication and higher success rates. Commercially bought training phantoms allow providers to develop tactile skills in a low-risk setting, but are also expensive and poorly accessible. This study analyzes the efficacy of homemade, low-cost, gelatin-based central line vascular models to teach vascular anatomy and intravascular access techniques in training physicians.

METHODS

A gelatin mold was created using a mixture of unflavored gelatin, hot water, psyllium husk powder, and rubbing alcohol. Latex tubing, balloons, precooked hot dog, and tofu were inserted to simulate arteries, veins, nerves, and the sternocleidomastoid muscle, respectively. Medical students from a single institution participated in a 90-minute workshop led by interventional radiology residents. Participants completed presurveys and postsurveys that assessed knowledge acquisition and confidence levels related to acquiring central access. All images were obtained using a USB-C Butterfly iQ probe.

RESULTS

Twenty medical students were analyzed after the workshop. There was a statistically significant increase in self-reported confidence in basic ultrasound use (adjusting gain, depth, probe manipulation), localizing major anatomical structures, using ultrasound for vessel access, and reported ease in identifying muscle, nerves, and major blood vessels under ultrasound. There was also a significant increase in correctly identified anatomical landmarks after the workshop, including the sternocleidomastoid muscle, internal jugular vein, carotid artery, femoral nerve, femoral artery, and femoral vein.

CONCLUSIONS

Our findings suggest that our homemade, low-cost, gelatin-based models were effective in teaching vascular anatomy and ultrasound-guided vascular access techniques to training physicians.

Pediatric Residents' Perceptions of a Point-of-Care Ultrasound Collaboration With Emergency Medicine

Background Pediatric residencies expanding their point-of-care ultrasound (POCUS) education face barriers, including a lack of established curriculum and qualified educators. Prior studies report partnerships between pediatrics and pediatric emergency medicine (PEM); however, many non-PEM emergency medicine (EM) physicians with POCUS fellowship training also have experience with pediatric POCUS and represent an alternate educational partner. Objectives To improve pediatric residents' POCUS skills through collaborative education with EM and evaluate perceptions of the teaching format and instructors. Methods First through third-year pediatric residents attended a half-day didactic and hands-on session about renal, lung, and musculoskeletal (MSK) POCUS. These educational sessions were led by EM faculty with POCUS fellowship training and assisted by EM residents. Post-session surveys were administered to pediatric residents to assess prior POCUS experience, changes in confidence in acquiring and interpreting renal, lung, and MSK POCUS images, and opinions about the educational format. Statistical analyses of the post-session survey data were performed using SPSS. Results Thirty-nine pediatric residents attended the session and completed the survey of 45 total residents in the program (86.7%), with 89.7% completing 10 or fewer POCUS studies. Residents' comfort level with performing lung POCUS increased from 5.1% to 82.1% (p < .001), renal POCUS from 10.3% to 76.9% (p < .001), and MSK POCUS from 7.7% to 84.6% (p < .001). 87.2% rated the educational format as effective, and 94.9% (37/39) rated emergency medicine faculty as 'very effective' in providing ultrasound education relevant to the practice of pediatrics. Conclusion Pediatric resident POCUS education taught by EM faculty with POCUS fellowship training was well-received by pediatric residents and significantly improved confidence in acquiring and interpreting POCUS.

The Evolution of Cardiovascular Ultrasound: A Review of Cardiac Point-of-Care Ultrasound (POCUS) Across Specialties

The use of cardiac point-of-care ultrasound (POCUS) is now widespread in clinics, emergency departments, and all areas of the hospital. Users include medical trainees, advanced practice practitioners, and attending physicians in many specialties and sub-specialties. Opportunities to learn cardiac POCUS and requirements for training vary across specialties as does the scope of the cardiac POCUS examination. In this review, we describe both a brief history of how cardiac POCUS emerged from echocardiography and the state of the art across a variety of medical fields.

Current Use and Barriers to Point-of-Care Ultrasound in Primary Care: A National Survey of VA Medical Centers

BACKGROUND

More primary care providers (PCPs) have begun to embrace the use of point-of-care ultrasound (POCUS), but little is known about how PCPs are currently using POCUS and what barriers exist. In this prospective study, the largest systematic survey of POCUS use among PCPs, we assessed the current use, barriers to use, program management, and training needs for POCUS in primary care.

METHODS

We conducted a prospective observational study of all VA Medical Centers (VAMCs) between June 2019 and March 2020 using a web-based survey sent to all VAMC Chiefs of Staff and Chiefs of primary care clinics (PCCs).

RESULTS

Chiefs of PCCs at 105 VAMCs completed the survey (82% response rate). Only 13% of PCCs currently use POCUS, and the most common applications used were bladder and musculoskeletal ultrasound. Desire for POCUS training exceeded current use, but lack of trained providers (78%), ultrasound equipment (66%), and funding for training (41%) were common barriers. Program infrastructure to support POCUS use was uncommon, and only 9% of VAMCs had local policies related to POCUS. Most PCC chiefs (64%) would support POCUS training.

CONCLUSIONS

Current use of POCUS in primary care is low despite the recent growth of POCUS training in Internal Medicine residency programs. Investment in POCUS training and program infrastructure is needed to expand POCUS use in primary care and ensure adequate supervision of trainees.

Implementation and Evaluation of a Longitudinal Flipped-Classroom Point-of-Care Ultrasound Curriculum at an Internal Medicine Residency Program

BACKGROUND

Point-of-care ultrasound (POCUS) has extensive clinical utility in internal medicine, but formal and uniform curricula in internal medicine are lacking.

OBJECTIVE

To determine the effectiveness of a longitudinal, flipped-classroom, academic half-day curriculum on internal medicine resident confidence, utilization, and changes in clinical management.

METHODS

We implemented an asynchronous, flipped-classroom, academic half-day curriculum from November 2020 to November 2021 and conducted an evaluation with a prospective, before-after cohort study. Curriculum included 4 rotating sessions comprised of 20 to 30 min of image interpretation followed by 1.5 to 2 h of image acquisition. Confidence was rated via Likert scale. Utilization was reported via indicating never, 1 to 2, 3 to 4, 5 to 6, or >6 times per month (recorded as 1-5, respectively). Image interpretation was assessed via a 6-question, multiple-choice video assessment.

RESULTS

Nineteen of 99 potential residents (19%) completed a pre- and post-curriculum evaluation. Residents attended a median of 4 sessions. Confidence improved from 2.47 to 3.53 (P = .002). Utilization did not improve overall (2.11-2.42, P = .22), but utilization of left ventricular function assessment (1.53-2.00, P = .046) and pulmonary assessment (1.53-2.00, P = .039) increased. The percentage of residents that had ever changed their clinical management by POCUS increased from 47% to 84% after implementation of the curriculum. Cardiac, pulmonary/pleural, volume assessment, and abdominal free fluid exams were reported as the most clinically useful.

CONCLUSION

Implementation of a longitudinal, academic half-day curriculum for POCUS resulted in improved confidence, increased POCUS utilization for the cardiac and pulmonary examination, and changes in clinical management based on POCUS.

Development and Assessment of Simulation-Based Point-of-Care Ultrasound Curriculum in Undergraduate Medical Education

OBJECTIVES

Implementation barriers and lack of standardized point-of-care ultrasound (POCUS) curricula make the development of effective POCUS curricula and methods of assessment challenging. The authors aim to develop a longitudinal POCUS curriculum through staged intervention. In the first stage, the authors hypothesized that the use of high-fidelity ultrasound simulation during the Internal Medicine clerkship would improve POCUS confidence and knowledge among medical students, minimizing the need for trained faculty.

METHODS

A quasi-experimental study of third-year students on the Internal Medicine clerkship at a large academic medical center in the United States was performed assessing the efficacy of ultrasound simulation use. The control group consisted of students who received baseline POCUS education during teaching rounds but did not have access to the ultrasound simulator. The experimental group consisted of students who, in addition to baseline POCUS education, had access to a high-fidelity ultrasound simulator throughout the clerkship for a minimum of 1 hour per week. Students in both the control and experimental groups completed a pre- and post-intervention confidence survey and knowledge-based examination.

RESULTS

Eighty-two percent (50/61) of students completed pre- and post-tests, with the control group demonstrating no significant difference in POCUS confidence or knowledge. After exposure to the ultrasound simulator, the experimental group demonstrated statistically significant improvement in POCUS confidence and overall POCUS knowledge (p < .01).

CONCLUSION

The use of high-fidelity ultrasound simulation can improve POCUS confidence and knowledge among medical students while addressing common barriers to the implementation of a POCUS curriculum. Despite showing statistically significant improvement in overall knowledge, the results did not appear to hold educational significance. Additional POCUS educational methods are necessary to overcome cognitive bias and potential overconfidence. The next stage of curriculum development will include resident-led POCUS workshops to supplement simulation.

Evaluation of a Novel Point-of-Care Ultrasound Curriculum for First-Year Pediatric Residents

OBJECTIVE

The aim of the study is to evaluate a novel point-of-care ultrasound (POCUS) educational curriculum for pediatric residents.

METHODS

The cohort study in graduate medical education was completed from January 2017 to March 2019. Postgraduate year 1 (PGY1) pediatric residents attended the educational curriculum that consisted of 3 half-day sessions over a 3-month period. Each session consisted of a lecture (introduction, extended focused assessment with sonography for trauma, soft tissue/musculoskeletal, cardiac, and resuscitative applications) followed by supervised hands-on scanning sessions. Group ratio was 3 learners to 1 machine/expert instructor. Main outcome measures included pre- and post-written test scores, as well as objective structured clinical examination (OSCE) scores.

RESULTS

Forty-nine PGY1 residents (78% women) completed the curriculum. The mean (SD) pretest score was 68% (8.5), and the mean posttest score was 83% (8.3) with a difference of 15 (95% confidence interval, 12.5-17.6; P < 0.001). Mean (SD) focused assessment with sonography for trauma OSCE score after the curriculum was 88.7% (11.9). The number of PGY1 pediatric residents that were comfortable performing POCUS examinations increased from pretraining to posttraining for soft tissue/musculoskeletal (14%-61%, P < 0.001), extended focused assessment with sonography for trauma (24%-90%, P < 0.001), and cardiac (18%-86%, P < 0.001). All participants found the curriculum useful, and 42 of 49 (86%) stated the curriculum increased their ability to acquire and interpret images.

CONCLUSIONS

Postgraduate year 1 pediatric residents learned the basics of POCUS through 3 brief educational sessions. The increase in posttest scores demonstrated improved POCUS knowledge, and the high OSCE score demonstrated their ability to acquire ultrasound images. Point-of-care ultrasound guidelines are needed for pediatric residency programs.

Pediatric Residency Point-of-Care Ultrasound Training Needs Assessment and Educational Intervention

Background Prior studies showed that point-of-care ultrasound (POCUS) training is not commonly offered in pediatric residency. We assessed the need for a pediatric POCUS curriculum by evaluating pediatric trainees' attitudes toward the use of POCUS and identifying barriers to training. We also aimed to evaluate the impact of a POCUS educational intervention on self-efficacy and behavior. Methods We conducted a cross-sectional survey of pediatric residents in a single large freestanding children's hospital distributed via an institutional listserv and administered online. The survey included opinion-rating of statements regarding POCUS and barriers to training. We also offered a two-week POCUS course with online modules and hands-on scanning. Participating residents completed pre- and post-course knowledge assessments and follow-up surveys up to 12 months following the course to assess POCUS use and self-report confidence on POCUS indications, acquisition, interpretation, and clinical application. Results Forty-nine respondents were included in the survey representing all three pediatric levels with 16 specialty interest areas. Ninety-six percent of trainees reported that POCUS is an important skill in pediatrics. Ninety-two percent of trainees reported that residency programs should teach residents how to use POCUS. The most important perceived barriers to POCUS training were scheduling availability for POCUS rotations and lack of access to an ultrasound machine. Fourteen participants completed the pre- and post-course knowledge tests, with eight and six participants also completing the six- and 12-month follow-up surveys, respectively. Self-ratings of confidence were significantly improved post-intervention in indications (P = 0.007), image acquisition (P = 0.002), interpretation (P = 0.002), and clinical application (P = 0.004). This confidence improvement was sustained up to 6-12 months (P = 0.004-0.032). Participants also reported higher categorical POCUS use after course completion (P = 0.031). Conclusions Pediatric trainees perceive POCUS as an important skill, hold favorable opinions towards the use of POCUS, and support POCUS training within a pediatric residency. A POCUS course can improve resident POCUS knowledge, instill confidence, and motivate higher POCUS use. Further study is needed to evaluate POCUS applications in pediatric medicine to develop a standardized POCUS curriculum and establish a training guideline for pediatric residency.

Current use, training, and barriers in point-of-care ultrasound in hospital medicine: A national survey of VA hospitals

BACKGROUND

Point-of-care ultrasound (POCUS) can reduce procedural complications and improve the diagnostic accuracy of hospitalists. Currently, it is unknown how many practicing hospitalists use POCUS, which applications are used most often, and what barriers to POCUS use exist.

OBJECTIVE

This study aimed to characterize current POCUS use, training needs, and barriers to use among hospital medicine groups (HMGs).

DESIGN, SETTING, AND PARTICIPANTS

A prospective observational study of all Veterans Affairs (VA) medical centers was conducted between August 2019 and March 2020 using a web-based survey sent to all chiefs of HMGs. These data were compared to a similar survey conducted in 2015.

RESULT

Chiefs from 117 HMGs were surveyed, with a 90% response rate. There was ongoing POCUS use in 64% of HMGs. From 2015 to 2020, procedural POCUS use decreased by 19%, but diagnostic POCUS use increased for cardiac (8%), pulmonary (7%), and abdominal (8%) applications. The most common barrier to POCUS use was lack of training (89%), and only 34% of HMGs had access to POCUS training. Access to ultrasound equipment was the least common barrier (57%). The proportion of HMGs with ≥1 ultrasound machine increased from 29% to 71% from 2015 to 2020. An average of 3.6 ultrasound devices per HMG was available, and 45% were handheld devices.

CONCLUSION

From 2015 to 2020, diagnostic POCUS use increased, while procedural use decreased among hospitalists in the VA system. Lack of POCUS training is currently the most common barrier to POCUS use among hospitalists.

Piloting a Graduate Medical Education Point-of-Care Ultrasound Curriculum

Objective

As point-of-care ultrasound (POCUS) use grows, training in graduate medical education (GME) is increasingly needed. We piloted a multispecialty GME POCUS curriculum and assessed feasibility, knowledge, and comfort with performing POCUS exams.

Methods

Residents were selected from the following residency programs: internal medicine, family medicine, emergency medicine, and a combined internal medicine/pediatrics program. Didactics occurred through an online curriculum that consisted of five modules: physics and machine operation, cardiac, lung, soft tissue, and extended focused sonography in trauma applications. Residents completed a pre- and post-curriculum questionnaire, as well as knowledge assessments before and after each module. One-hour hands-on training sessions were held for each module. Differences between pre- and post-participation questionnaire responses were analyzed using the Wilcoxon rank sum.

Results

Of the 24 residents selected, 21 (86%) were post-graduate year two or three, and 16 (65%) were from the internal medicine program. Eighteen (67%) residents reported limited prior POCUS experience. All pre- to post-knowledge assessment scores increased (p<0.05). Statistically significant increases pre- to post-curriculum were found for frequency of POCUS use (p = 0.003), comfort in using POCUS for assessing for abdominal aortic aneurysm, soft tissue abscess detection, undifferentiated hypotension and dyspnea, cardiac arrest and heart failure (p<0.025); and competency in machine use, acquiring and interpreting images and incorporating POCUS into clinical practice (p<0.001). All participants felt the skills learned during this curriculum were essential to their future practice.

Conclusions

In this pilot, we found using a combination of online and hands-on training to be feasible, with improvement in residents’ knowledge, comfort, and use of POCUS.

Development of a Point-of-Care Ultrasound Track for Internal Medicine Residents

BACKGROUND

Point-of-care ultrasound (POCUS) training has been increasing among internal medicine (IM) residency programs, but few programs can provide longitudinal training due to barriers such as lack of trained faculty.

AIM

Describe the development of a longitudinal POCUS track for IM residents using local and external resources, including a national POCUS certificate program.

SETTING

University-based IM residency program affiliated with a public and veterans affairs hospital.

PARTICIPANTS

Twelve IM residents from 2018 to 2021.

PROGRAM DESCRIPTION

Residents complete a national POCUS certificate program by attending live courses and completing online modules, an image portfolio, and final knowledge/skills assessments. Locally, residents participate in 1-month procedure and diagnostic POCUS rotations and provide peer-to-peer POCUS teaching of residents and medical students.

PROGRAM EVALUATION

The POCUS track increased residents' use and comfort with diagnostic and procedural applications. All residents rated being satisfied or very satisfied with the track and would recommend it to prospective applicants (100%). The most commonly reported barriers to utilizing POCUS per residents were time constraints (83%), lack of available ultrasound equipment (83%), and lack of trained faculty (58%).

DISCUSSION

IM residency programs with limited faculty expertise in POCUS can leverage external resources to provide longitudinal POCUS training to its residents.

A Healthcare Physician Can Be Trained to Perform Intestinal Ultrasound in Children With Inflammatory Bowel Disease

OBJECTIVES

Training healthcare physicians to perform intestinal ultrasound (IUS) during outpatient visits with equal accuracy as radiologists could improve clinical management of IBD patients. We aimed to assess whether a healthcare-physician can be trained to perform IUS, with equal accuracy compared with experienced radiologists in children with iBD, and to assess inter-observer agreement.

METHODS

Consecutive children, 6 to 18 years with IBD or suspicion of IBD, who underwent ileo-colonoscopy were enrolled. iUS was performed independently by a trained healthcare-physician and a radiologist in 1 visit. Training existed of an international training curriculum for IUS. Operators were blinded for each other's IUS, and for the ileocolonoscopy. Difference in accuracy of IUS by the healthcare-physician and radiologist was assessed using areas under the ROC curve (AUROC). Inter-observer variability was assessed in terminal ileum (TI), transverse colon (TC) and descending-colon (DC), for disease activity (ie, bowel wall thickness [BWT] >2 mm with hyperaemia or fat-proliferation, or BWT >3 mm).

RESULTS

We included 73 patients (median age 15, interquartile range [IQR]:13-17, 37 [51%] female, 43 [58%] with Crohn disease). AUROC ranged between 0.71 and 0.81 for the healthcare-physician and between 0.67 and 0.79 for radiologist (P  > 0.05). Inter-observer agreement for disease activity per segment was moderate (K: 0.58 [SE: 0.09], 0.49 [SE: 0.12], 0.52 [SE: 0.11] respectively for TI, TC, and DC).

CONCLUSIONS

A healthcare- physician can be trained to perform IUS in children with IBD with comparable diagnostic accuracy as experienced radiologists. The interobserver agreement is moderate. Our findings support the usage of IUS in clinical management of children with IBD.

Residents' Perspective on Need for Point-of-Care Ultrasound Education During Pediatric Residency

OBJECTIVES

Many medical disciplines incorporate point-of-care ultrasound (POCUS) into their practice. Despite well-defined applications, POCUS has not been widely adopted in pediatrics and is not commonly taught during residency. Our objective was to profile the current state of POCUS education in pediatric residency training from the resident perspective.

METHODS

We surveyed pediatric trainees about their POCUS education, general opinions about POCUS, and perceived barriers to POCUS training in residency. We distributed the survey to a random sample of Ohio pediatric residents, stratified by program size and training level. Descriptive statistics were used to characterize responses.

RESULTS

We sampled 66.4% of the population (371 of 559) of Ohio pediatric residents and achieved a response rate of 59.3%. Only 15% of respondents received POCUS training during residency, with 85% having never performed a POCUS scan. Most (86%) desired POCUS education and 67% believed it should be required during residency. Residents felt that POCUS would be useful for procedural guidance (95%), clinical diagnosis (94%), and patient safety (74%). Most residents (61%) believed POCUS education would benefit their careers, particularly those planning on subspecialization. Barriers to POCUS education included lack of an established curriculum (75%), competing educational priorities (58%), and a shortage of qualified instructors (52%).

CONCLUSIONS

Although Ohio pediatric residents do not receive formal POCUS education in residency, they desire such training and believe it would benefit their future practice. Consensus on scope of practice, development of a standardized curriculum, and increased faculty training in POCUS may help address this educational gap.

Motivations, barriers, and professional engagement: a multisite qualitative study of internal medicine faculty's experiences learning and teaching point-of-care ultrasound

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.

The unmet demand for point-of-care ultrasound among general pediatricians: a cross-sectional survey

BACKGROUND

Point-of-care ultrasound (POCUS) is a noninvasive bedside tool with many pediatric applications but is not currently a formal part of pediatric training and practice. Formal surveys of general pediatricians regarding POCUS training are lacking. We aimed to quantify the baseline ultrasound experience and training needs of general pediatricians and pediatric residents across different practice settings.

METHODS

In 2020, we sent an online survey to 485 current faculty, residents, and graduates from an urban pediatric academic medical center in Northern California. Pediatric subspecialists were excluded. Survey questions about baseline experience, comfort, and perceived usefulness of 20 common POCUS applications were developed by two POCUS experts using existing literature. Chi-squared analysis was used to compare residents versus attendings and to compare attendings practicing in inpatient versus outpatient versus mixed settings.

RESULTS

Response rate was 20% (98/485). Compared to attendings (n = 73), residents (n = 25) endorsed more exposure to POCUS in medical school (32% vs 5%, p = 0.003) and residency (12% vs 5%, p = 0.003). Respondents endorsed low comfort with POCUS (mean 1.3 out of 5 on Likert scale). Of 20 procedural and diagnostic applications, respondents identified abscess drainage, bladder catheterization, soft tissue, neck, advanced abdominal, and constipation as most useful. Overall, 50% of pediatricians (and 70% of pediatric residents) responded that there were opportunities to use POCUS multiple times a week or more in their clinical practice.

CONCLUSIONS

There is an unmet demand for POCUS training among general pediatricians and trainees in our study. Although the majority of respondents were not POCUS users, our results could guide future efforts to study the role of POCUS in general pediatrics and develop pediatric curricula.

Point-of-Care Ultrasound Training Programs Across Italian Pediatric Residency Schools: A National Survey

INTRODUCTION

The role of point-of-care ultrasound (POCUS) in routine clinical practice is rapidly growing, whereas adult specialties have already included training programs regarding this topic; pediatric residency schools are still late on this topic, particularly in Italy.

METHODS

We performed an online anonymous survey to Italian residents. The online survey has been submitted to the resident representatives of each pediatric residency school in Italy by the Italian Observatory of Pediatric Residents; each representative in turn distributed it to the pediatric residents of his own school.

RESULTS

Three sixty-one residents responded to the survey. Only 7.8% of residents declared that in their residency school, an official training program on POCUS exists, although more than 95% of respondents declared that such a training would be of primary importance for their future practice. Most residents do not know how to use an ultrasound machine nor the differences between different probes.

CONCLUSIONS

Our results demonstrate that POCUS training is still missing in Italy. Given the growing number of evidences of the benefits from including POCUS in clinical practice and patient evaluation, efforts are needed to fill this gap, in Italy and, probably, in most European countries. Such a training will definitely help the new generation of pediatricians improve their curriculum and, therefore, child health.

Point-of-Care Ultrasound Training in Pediatric Residency: A National Needs Assessment

BACKGROUND AND OBJECTIVES

As point-of-care ultrasound (POCUS) evolves into a standard tool for the care of children, pediatric residency programs need to develop POCUS training programs. Few POCUS training resources exist for pediatric residents, and little is known about POCUS training in pediatric residencies. We aim to describe pediatric residency leadership perspectives regarding the value of POCUS and to elucidate the current state of POCUS training in pediatric residency programs.

METHODS

A group of pediatric educators and POCUS experts developed a novel survey followed by cognitive interviews to establish response-process validity. The survey was administered electronically to pediatric residency associate program directors between December 2019 and April 2020. Program characteristics, including region, setting, and size, were used to perform poststratification for analyses. We performed comparative analyses using program and respondent characteristics.

RESULTS

We achieved a 30% (58 of 196) survey response rate. Although only a minority of respondents (26%) used POCUS in clinical practice, a majority (56%) indicated that all pediatric residents should be trained in POCUS. A majority of respondents also considered 8 of 10 POCUS applications important for pediatric residents. Only 37% of programs reported any POCUS training for residents, primarily informal bedside education. Most respondents (94%) cited a lack of qualified instructors as a barrier to POCUS training.

CONCLUSIONS

Most pediatric residency programs do not provide residents with POCUS training despite its perceived value and importance. Numerous POCUS applications are considered important for pediatric residents to learn. Future curricular and faculty development efforts should address the lack of qualified POCUS instructors.

Advancing Internal Medicine Training: Experience of a Bedside Procedure Service as a Resident Elective

BACKGROUND

In 2007, the American Board of Internal Medicine eliminated numeric procedure requirements for licensing. The level of exposure to procedures during residency, and subsequent competence of graduating residents, is variable. In 2015, our institution developed a bedside procedure service (BPS) with the intent to teach ultrasound guidance and procedural training to internal medicine residents with direct supervision of technique by Hospital Medicine faculty to optimize learning, increase confidence, and improve patient safety.

OBJECTIVE

In this study, we review the number and complication rates of resident procedures on a dedicated internal medicine bedside procedure service (BPS) as a resident elective.

METHODS

In this retrospective, observational, single-center study, we reviewed internally collected data from BPS procedures performed from 2015-2019. The BPS offers a variety of procedures done with ultrasound guidance at an adult tertiary care referral center. BPS services are available to all inpatient hospital services. A rotation with the BPS was offered as a stand-alone resident elective for the first time in 2015.

RESULTS

69 residents performed a total of 2700 ultrasound-guided/assisted procedures and 146 diagnostic ultrasound scans from 2015-2019. Residents performed an average of 40 procedures during their elective month. There were 5 resident performed procedural complications with an overall complication rate of 0.19%.

CONCLUSIONS

Our BPS increased procedural opportunities for residents and allowed for real-time feedback by an experienced faculty member in a one-on-one setting. A dedicated rotation allows the time to focus on becoming proficient in invasive procedures with expert supervision.

Interprofessional Point-of-Care Ultrasound Training of Resident Physicians by Sonography Student-Coaches

INTRODUCTION

Point-of-care ultrasound (POCUS) education is growing throughout medical education, but many institutions lack POCUS-trained faculty. Interprofessional education offers a strategy for expanding the pool of available teachers while providing an opportunity for collaboration between health professional students.

METHODS

Six students enrolled in the diagnostic medical sonography (DMS) program participated in a case-based, train-the-trainer session to practice a standardized approach for POCUS instruction. They then served as coaches to 25 first-year internal medicine residents learning to perform ultrasound exams of the kidneys, bladder, and aorta. Course assessment included an objective structured exam (OSCE), coaching evaluations, and course evaluations.

RESULTS

Residents scored an average of 81% (71.3 out of 88 points, SD = 7.5) on the OSCE. Residents rated the DMS student-coaches positively on all teacher evaluation questions. Both the residents and DMS student-coaches gave positive course evaluations scores.

DISCUSSION

An interprofessional workshop with DMS students coaching internal medicine residents was an effective strategy for teaching POCUS skills. This approach may offer a solution for programs wanting to implement POCUS training with limited faculty expertise or time.

First year internal medicine residents' self-report point-of-care ultrasound knowledge and skills: what (Little) difference three years make

BACKGROUND

With increasing availability of point-of-care ultrasound (POCUS) education in medical schools, it is unclear whether or not learning needs of junior medical residents have evolved over time.

METHODS

We invited all postgraduate year (PGY)-1 residents at three Canadian internal medicine residency training programs in 2019 to complete a survey previously completed by 47 Canadian Internal Medicine PGY-1 s in 2016. Using a five-point Likert scale, participants rated perceived applicability of POCUS to the practice of internal medicine and self-reported skills in 15 diagnostic POCUS applications and 9 procedures.

RESULTS

Of the 97 invited residents, 58 (60 %) completed the survey in 2019. Participants reported high applicability but low skills across all POCUS applications and procedures. The 2019 cohort reported higher skills in assessing pulmonary B lines than the 2016 cohort (2.3 ± SD 1.0 vs. 1.5 ± SD 0.7, adjusted p-value = 0.01). No other differences were noted.

CONCLUSIONS

POCUS educational needs continue to be high in Canadian internal medicine learners. The results of this needs assessment study support ongoing inclusion of basic POCUS elements in the current internal medicine residency curriculum.

Design of a point-of-care ultrasound curriculum for pediatric emergency medicine fellows: A Delphi study

OBJECTIVES

There has been a steady increase in the growth and utilization of point-of-care ultrasound (POCUS) in pediatric emergency medicine (PEM). POCUS has been established as an Accreditation Council for Graduate Medical Education (ACGME) core requirement for accreditation of PEM fellowship programs. Despite this requirement, training guidelines regarding POCUS knowledge and skills have yet to be developed. The purpose of this project was to develop a curriculum and a competency checklist for PEM fellow POCUS education.

METHODS

We formed a core leadership group based on expertise in one or more key areas: PEM, POCUS, curriculum development, or Delphi methods. We recruited 29 PEM POCUS or ultrasound education experts from North America to participate in a three-round electronic Delphi project. The first Delphi round asked experts to generate a list of the core POCUS knowledge and skills that a PEM fellow would need during training to function as an autonomous practitioner. Subsequent rounds prioritized the list of knowledge and skills, and the core leadership group organized knowledge and skills into global competencies and subcompetencies.

RESULTS

The first Delphi round yielded 61 POCUS areas of knowledge and skills considered important for PEM fellow learning. After two subsequent Delphi rounds, the list of POCUS knowledge and skills was narrowed to 38 items that addressed elements of six global competencies. The core leadership group then revised items into subcompetencies and categorized them under global competencies, developing a curriculum that defined the scope (depth of content) and sequence (order of teaching) of these POCUS knowledge and skill items.

CONCLUSIONS

This expert, consensus-generated POCUS curriculum provides detailed guidance for PEM fellowships to incorporate POCUS education into their programs. Our curriculum also identifies core ultrasound knowledge and skills needed by PEM fellows to perform the specific POCUS applications recommended in prior publications.

Non-radiologist-performed abdominal point-of-care ultrasonography in paediatrics - a scoping review

BACKGROUND

Historically, US in the paediatric setting has mostly been the domain of radiologists. However, in the last decade, there has been an uptake of non-radiologist point-of-care US.

OBJECTIVE

To gain an overview of abdominal non-radiologist point-of-care US in paediatrics.

MATERIALS AND METHODS

We conducted a scoping review regarding the uses of abdominal non-radiologist point-of-care US, quality of examinations and training, patient perspective, financial costs and legal consequences following the use of non-radiologist point-of-care US. We conducted an advanced search of the following databases: Medline, Embase and Web of Science Conference Proceedings. We included published original research studies describing abdominal non-radiologist point-of-care US in children. We limited studies to English-language articles from Western countries.

RESULTS

We found a total of 5,092 publications and selected 106 publications for inclusion: 39 studies and 51 case reports or case series on the state-of-art of abdominal non-radiologist point-of-care US, 14 on training of non-radiologists, and 1 each on possible harms following non-radiologist point-of-care US and patient satisfaction. According to included studies, non-radiologist point-of-care US is increasingly used, but no standardised training guidelines exist. We found no studies regarding the financial consequences of non-radiologist point-of-care US.

CONCLUSION

This scoping review supports the further development of non-radiologist point-of-care US and underlines the need for consensus on who can do which examination after which level of training among US performers. More research is needed on training non-radiologists and on the costs-to-benefits of non-radiologist point-of-care US.

Operating bedside cardiac ultrasound program in emergency medicine residency: A retrospective observation study from the perspective of performance improvement

Background

Point-of-care ultrasound is one of useful diagnostic tools in emergency medicine practice and considerably depends on physician’s performance. This study was performed to evaluate performance improvements and favorable attitudes through structured cardiac ultrasound program for emergency medicine residents.

Methods

Retrospective observational study using the point-of-care ultrasound (PoCUS) database in one tertiary academic-teaching hospital emergency department has been conducted. Cardiac ultrasound education and rotation program has been implemented in emergency medicine residency program. Structured evaluation sheet for cardiac ultrasound and questionnaire toward PoCUS have been developed. An early-phase and a late-phase case were selected randomly for each participant. Two emergency medicine specialists with expertise in PoCUS evaluated saved images independently. We used a paired t-test to compare the performance score of each phase and the results of the questionnaire. Multivariable linear regression analysis was conducted to evaluate the association between the characteristics of participants and performance improvements.

Results

During the study period, a total of 1,652 bedside cardiac ultrasounds were administered. Forty-six examinations conducted by 23 emergency medicine residents were randomly selected for analysis. The performance score increased from 39.5 to 56.1 according to expert A and 45.3 to 62.9 according to expert B (p-value <0.01 for both). The average questionnaire score, which was analyzed for 17 participants, showed improvement from 18.9 to 20.7 (p-value <0.01). In multivariable linear regression analysis, younger age, higher early-phase score and higher confidence had a negative association with a greater improvement of performance, while the number of examinations had a positive association.

Conclusions

Bedside cardiac ultrasound performance and attitudes toward PoCUS have been improved through structured residency program.

Evaluating a longitudinal point-of-care-ultrasound (POCUS) curriculum for pediatric residents

BACKGROUND

POCUS is a growing field in medical education, and an imaging modality ideal for children given the lack of ionizing radiation, ease of use, and good tolerability. A 2019 literature review revealed that no US pediatric residency programs integrated obligatory POCUS curricula. Our objective was to provide a formalized POCUS curriculum over multiple years, and to retrospectively assess improvement in resident skills and comfort.

METHODS

During intern year, pediatric residents received didactics and hands-on scanning opportunities in basic POCUS applications. Their evaluation tools included pre- and post-surveys and tests, and a final performance exam. In the second and third years of residency, all participants were required to complete 8 hours per year of POCUS content review and additional hands-on training. An optional third-year curriculum was offered to interested residents as career-focused education elective time.

RESULTS

Our curriculum introduced POCUS topics such as basic and advanced cardiac, lung, skin/soft tissues and procedural based ultrasound to all pediatric residents. Among first-year residents, application-specific results showed POCUS comfort level improved by 61-90%. Completed evaluations demonstrated improvement in their ability to recognize and interpret POCUS images. Second- and third-year residents reported educational effectiveness that was rated 3.9 on a 4-point Likert scale. Four third-year residents took part in the optional POCUS elective, and all reported a change in their practice with increased POCUS incorporation.

CONCLUSIONS

Our longitudinal pediatric residency POCUS curriculum is feasible to integrate into residency training and exhibits early success.

A Mixed-Methods Evaluation of Medical Residents' Attitudes Towards Interprofessional Learning and Stereotypes Following Sonography Student-Led Point-of-Care Ultrasound Training

BACKGROUND

Point-of-care ultrasound (POCUS) training is growing across internal medicine graduate medical education, but lack of trained faculty is a barrier to many programs. Interprofessional education (IPE) may offer a solution but must overcome potential biases of trainees.

AIM

To evaluate the impact of an interprofessional POCUS training on residents' attitudes towards interprofessional learning and stereotypes.

SETTING

Midwestern health sciences university.

PARTICIPANTS

Diagnostic medical sonography (DMS) students (n = 13) served as teachers for first-year internal medicine residents (IMR) (n = 49).

PROGRAM DESCRIPTION

DMS students participated in a train-the-trainer session to learn teaching strategies via case-based simulation, then coached IMR to acquire images of the kidneys, bladder, and aorta on live models.

PROGRAM EVALUATION

Mixed-methods evaluation, including pre-/post-surveys and focus group interviews. The survey response rate was 100% (49/49 IMR). Composite survey scores evaluating residents' attitudes towards IPE and stereotyping of sonographers improved significantly following the intervention. Qualitative analysis of focus group interviews yielded four themes: enhanced respect for other disciplines, implications for future practice, increased confidence of DMS students, and interest in future IPE opportunities.

DISCUSSION

Interprofessional POCUS education can improve residents' perceptions towards IPE, increase their level of respect for sonographers, and motivate interest in future interprofessional collaboration.

Analysis of lawsuits related to diagnostic errors from point-of-care ultrasound in internal medicine, paediatrics, family medicine and critical care in the USA

PURPOSE

The purpose of this study is to identify the extent of diagnostic error lawsuits related to point-of-care ultrasound (POCUS) in internal medicine, paediatrics, family medicine and critical care, of which little is known.

METHODS

We conducted a retrospective review of the Westlaw legal database for indexed state and federal lawsuits involving the diagnostic use of POCUS in internal medicine, paediatrics, family medicine and critical care. Retrieved cases were reviewed independently by three physicians to identify cases relevant to our study objective. A lawyer secondarily reviewed any cases with discrepancies between the three reviewers.

RESULTS

Our search criteria returned 131 total cases. Ultrasound was mentioned in relation to the lawsuit claim in 70 of the cases returned. In these cases, the majority were formal ultrasounds performed and reviewed by the radiology department, echocardiography studies performed by cardiologists or obstetrical ultrasounds. There were no cases of internal medicine, paediatrics, family medicine or critical care physicians being subjected to adverse legal action for their diagnostic use of POCUS.

CONCLUSION

Our results suggest that concerns regarding the potential for lawsuits related to POCUS in the fields of internal medicine, paediatrics, family medicine and critical care are not substantiated by indexed state and federal filed lawsuits.
