Physician Assistant Student Preceptors and Point-of-Care Ultrasound: Perceptions and Readiness to Teach.

PURPOSE: Point-of-care ultrasound (POCUS) inclusion in medical education is increasing, and understanding of clinical educators' perceptions and use patterns is needed. The purpose of this research project was to explore current use, interest, knowledge, perceptions, and readiness to teach POCUS from the perspectives of clinical preceptors for physician assistant (PA) students. METHODS: A survey research study was completed on previously identified preceptors. Descriptive statistics outlined the frequencies of responses. Bivariate analysis with Chi-Square or Fischer Exact Testing was used to identify statistically significant differences between groupings. RESULTS: Most preceptors (87.1%) believe POCUS adds clinical value, but a minority received POCUS training (37%), are familiarity with its use (37.4%), and currently use POCUS (23.4%). Two-thirds (66.1%) of preceptors stated they would allow PA students to practice POCUS skills on clinical rotation; however, few (31%) felt comfortable with this and even fewer (22.6%) felt comfortable findings on POCUS into their clinical decision making. CONCLUSIONS: Despite support of incorporation of POCUS into PA education, clinical preceptors' readiness to teach POCUS on clinical rotations is limited. This study shows that preceptors are neither comfortable with student use nor incorporating student findings into clinical decision making. A lack of sufficient clinical preceptors to support POCUS education has not been previously reported. PA programs attempting to incorporate POCUS into their curricula will need to be intentional providing opportunities to continue POCUS on clinical rotations.

Learning curves for point-of-care ultrasound image acquisition for novice learners in a longitudinal curriculum.

BACKGROUND: A learning curve is graphical representation of the relationship between effort, such as repetitive practice or time spent, and the resultant learning based on specific outcomes. Group learning curves provide information for designing educational interventions or assessments. Little is known regarding the learning curves for Point-of-Care Ultrasound (POCUS) psychomotor skill acquisition of novice learners. As POCUS inclusion in education increases, a more thorough understanding of this topic is needed to allow educators to make informed decisions regarding curriculum design. The purpose of this research study is to: (A) define the psychomotor skill acquisition learning curves of novice Physician Assistant students, and (B) analyze the learning curves for the individual image quality components of depth, gain and tomographic axis. RESULTS: A total of 2695 examinations were completed and reviewed. On group-level learning curves, plateau points were noted to be similar for abdominal, lung, and renal systems around 17 examinations. Bladder scores were consistently good across all exam components from the start of the curriculum. For cardiac exams, students improved even after 25 exams. Learning curves for tomographic axis (angle of intersection of the ultrasound with the structure of interest) were longer than those for depth and gain. Learning curves for axis were longer than those for depth and gain. CONCLUSION: Bladder POCUS skills can be rapidly acquired and have the shortest learning curve. Abdominal aorta, kidney, and lung POCUS have similar learning curves, while cardiac POCUS has the longest learning curve. Analysis of learning curves for depth, axis, and gain demonstrates that axis has the longest learner curve of the three components of image quality. This finding has previously not been reported and provides a more nuanced understanding of psychomotor skill learning for novices. Learners might benefit from educators paying particular attention to optimizing the unique tomographic axis for each organ system.

Physician Assistant Students' Perspective on Ultrasound as an Educational Technology.

INTRODUCTION: The use of ultrasound as an educational technology in medical education to teach basic sciences, including anatomy and physical examination techniques, has become common. Multiple studies have demonstrated the benefits of using ultrasound to teach anatomy and physical examination skills; however, this has not been studied in physician assistant (PA) students. METHODS: This qualitative phenomenological research used 5 semi-structured interviews of first semester PA students to obtain a deeper understanding of students' perspectives. Dominant coding categories were identified through open coding, and thematic analysis was completed to identify emerging themes of participants' perspectives. RESULTS: Overall, the students positively perceived this use of ultrasound. Four themes emerged regarding PA students' perspectives of ultrasound as an educational technology within their Clinical Anatomy and History and Physical Examination classes: solidifying the curriculum, desiring more, looking ahead, and burden of curriculum. DISCUSSION: This study supports the use of ultrasound as an educational technology to solidify prior learning; however, steps to ensure student commitment to the technology should be taken. Careful consideration for curricular sequencing and allocation of time should be utilized by programs attempting to integrate ultrasound in this manner. Hands-on experiences, rather than faculty demonstrations, and clinical correlation should be utilized whenever possible.

An Integrated Point-of-Care Ultrasound Curriculum: An Evidence-Based Approach.

ABSTRACT: Point-of-care ultrasound (POCUS) has been demonstrated to improve students' medical knowledge and clinical exam skills and advances patient care through numerous diagnostic and therapeutic applications. Despite the growing use of ultrasound in medical education and clinical practice, few physician assistant (PA) programs have successfully integrated POCUS education into their curricula. This manuscript describes an evidence-based approach for integrating POCUS education throughout a 2-year PA curriculum, with the goal of serving as a useful guidepost for other PA programs as they strive to incorporate this valuable skill into their curricula.

Development of the Proposed 13 Entrustable Professional Activities for Physician Assistant Graduates.

ABSTRACT: Competency-based training has not consistently produced medical professionals who are ready to practice. To address this situation, entrustable professional activities (EPAs) have been introduced as a means to assess medical trainee readiness for their next phase of training or practice. Thirteen EPAs were developed by the Physician Assistant Education Association (PAEA) Presidents Commission in 2016 to indicate what activities they thought future physician assistant (PA) students should be expected to perform at the completion of their PA education. The 13 EPAs as proposed by the PAEA Presidents Commission were adopted by the Mayo Clinic PA program and further developed through multiple steps, including (1) Discovery and Alignment; (2) EPA Development; (3) Curriculum Development; (4) Assessment and Rubric Development, and (5) Implementation.

Examining intercultural sensitivity and competency of physician assistant students.

Training in intercultural competency for health care professionals is necessary to bring greater balance to the disparity currently found among those needing health care. The purpose of this study was to determine what, if any, improvements in cultural competency were measurable in physician assistant (PA) students as they matriculated, using the Multicultural Awareness, Knowledge and Skills Survey-Revised as a pretest upon program entry and again as a posttest on the final day of the program. Ninety-three PA students from four successive classes graduating from a private midwest college between 2003 and 2007 participated in the pre and post measurements. All students were enrolled in specific didactic studies and clinical experiences in cultural sensitivity and competency. The results demonstrated significant improvement in knowledge (pretest 2.63, posttest 2.76, p=0.001) and skills (pretest 2.63, posttest 2.93, p<0.001) for all classes combined. The Intercultural Development Inventory was administered to the most recent graduating class to further explore these results. This cohort showed the highest scores (group mean 3.58 on scale of 1-5) in the Minimization developmental stage, which emphasizes cultural commonality over cultural distinctions. Enhanced curricular instruction such as exploring cultural assessment methods and controversies in health care differences, combined with increased clinical experiences with diverse cultures, are recommended to help move students past the minimization stage to gain greater cultural competency.

Physician assistants as servant leaders: meeting the needs of the underserved.

PURPOSE: The purpose of this study was to determine if the level of servant leader characteristics in clinically practicing physician assistants (PAs) in underserved populations differed from PAs serving in other locales. METHODS: Five subscales of servant leadership: altruistic calling, emotional healing, wisdom, persuasive mapping, and organizational stewardship, were measured in a quantitative study of clinically practicing PAs using a self-rating survey and a similar survey by others rating the PA. RESULTS: Of 777 PAs invited, 321 completed the survey. On a scale of 1 to 5, mean PA self-ratings ranged from 3.52 (persuasive mapping) to 4.05 (wisdom). Other raters' scores paired with the self-rated PA scores were comparable in all subscales except wisdom, which was rated higher by the other raters (4.32 by other raters, 4.01 by PAs, P= .002). There was no significant difference in the measures of servant leadership reported by PAs serving the underserved compared to PAs serving in other populations. Servant leader subscales were higher for PAs compared to previous studies of other health care or community leader populations. CONCLUSION: The results found that the PA population studied had a prominent level of servant leadership characteristics that did not differ between those working with underserved and nonunderserved populations.
