Breath Measurement Method for Synchronized Reproduction of Biological Tones in an Augmented Reality Auscultation Training System.

An educational augmented reality auscultation system (EARS) is proposed to enhance the reality of auscultation training using a simulated patient. The conventional EARS cannot accurately reproduce breath sounds according to the breathing of a simulated patient because the system instructs the breathing rhythm. In this study, we propose breath measurement methods that can be integrated into the chest piece of a stethoscope. We investigate methods using the thoracic variations and frequency characteristics of breath sounds. An accelerometer, a magnetic sensor, a gyro sensor, a pressure sensor, and a microphone were selected as the sensors. For measurement with the magnetic sensor, we proposed a method by detecting the breathing waveform in terms of changes in the magnetic field accompanying the surface deformation of the stethoscope based on thoracic variations using a magnet. During breath sound measurement, the frequency spectra of the breath sounds acquired by the built-in microphone were calculated. The breathing waveforms were obtained from the difference in characteristics between the breath sounds during exhalation and inhalation. The result showed the average value of the correlation coefficient with the reference value reached 0.45, indicating the effectiveness of this method as a breath measurement method. And the evaluations suggest more accurate breathing waveforms can be obtained by selecting the measurement method according to breathing method and measurement point.

Developing Medical Education Curriculum Reform Strategies to Address the Impact of Generative AI: Qualitative Study.

BACKGROUND: Generative artificial intelligence (GAI), represented by large language models, have the potential to transform health care and medical education. In particular, GAI's impact on higher education has the potential to change students' learning experience as well as faculty's teaching. However, concerns have been raised about ethical consideration and decreased reliability of the existing examinations. Furthermore, in medical education, curriculum reform is required to adapt to the revolutionary changes brought about by the integration of GAI into medical practice and research. OBJECTIVE: This study analyzes the impact of GAI on medical education curricula and explores strategies for adaptation. METHODS: The study was conducted in the context of faculty development at a medical school in Japan. A workshop involving faculty and students was organized, and participants were divided into groups to address two research questions: (1) How does GAI affect undergraduate medical education curricula? and (2) How should medical school curricula be reformed to address the impact of GAI? The strength, weakness, opportunity, and threat (SWOT) framework was used, and cross-SWOT matrix analysis was used to devise strategies. Further, 4 researchers conducted content analysis on the data generated during the workshop discussions. RESULTS: The data were collected from 8 groups comprising 55 participants. Further, 5 themes about the impact of GAI on medical education curricula emerged: improvement of teaching and learning, improved access to information, inhibition of existing learning processes, problems in GAI, and changes in physicians' professionality. Positive impacts included enhanced teaching and learning efficiency and improved access to information, whereas negative impacts included concerns about reduced independent thinking and the adaptability of existing assessment methods. Further, GAI was perceived to change the nature of physicians' expertise. Three themes emerged from the cross-SWOT analysis for curriculum reform: (1) learning about GAI, (2) learning with GAI, and (3) learning aside from GAI. Participants recommended incorporating GAI literacy, ethical considerations, and compliance into the curriculum. Learning with GAI involved improving learning efficiency, supporting information gathering and dissemination, and facilitating patient involvement. Learning aside from GAI emphasized maintaining GAI-free learning processes, fostering higher cognitive domains of learning, and introducing more communication exercises. CONCLUSIONS: This study highlights the profound impact of GAI on medical education curricula and provides insights into curriculum reform strategies. Participants recognized the need for GAI literacy, ethical education, and adaptive learning. Further, GAI was recognized as a tool that can enhance efficiency and involve patients in education. The study also suggests that medical education should focus on competencies that GAI hardly replaces, such as clinical experience and communication. Notably, involving both faculty and students in curriculum reform discussions fosters a sense of ownership and ensures broader perspectives are encompassed.

The positive effect of student-oriented clinical clerkship rounds employing role-play and peer review on the clinical performance and professionalism of clerkship students.

Background: Role-play (RP) and peer review (PR) are occasionally used in training and evaluating communication skills in clinical clerkship (CC). Thus, we evaluated the effect of combining RP and PR during student-oriented CC rounds.Methods: Clerkship students conducted medical interviews with and performed physical examinations on their patients, which were reviewed by five peer students who observed their performance while role-playing as senior physicians or patients' families. The peer reviewers then provided feedback to the students. The performance of the students was evaluated based on a mini-clinical evaluation exercise (Mini-CEX) and a professionalism mini-evaluation exercise (P-MEX) before and after the rounds by two attending physicians. After the CC, the students responded to questionnaires about the rounds.Results: Seventy-five students completed the rounds, and the duration of each round was 41.7 ± 7.1 min. Their communication skills and professionalism abilities on Mini-CEX and P-MEX showed significant improvement after the rounds. Improvements in medical interviewing and physical examinations were also noted. Additionally, the students recognized the importance of multiple viewpoints in patient care through experiences of the rounds.Conclusions: Combining RP and PR with CC rounds improves the students' clinical performance and professionalism and promotes their awareness of the importance of multiple viewpoints in patient care.

Usefulness of a short training seminar on how to handle difficult patients in simulated education.

OBJECTIVE: To evaluate a short-time simulation training seminar on how to handle difficult patients using professional simulated patients (SPs) such as actors. PARTICIPANTS: Sixty-three second-year residents at Chiba University Hospital between 2015 and 2017 who only attended the seminar once. INTERVENTION: The participants were divided into small groups, each of which was assigned a supervisory doctor as facilitator. Those who were playing the doctor's role enacted a medical interview with an SP. After the interview, the facilitator, the SP, and the observing residents participated in a debriefing while watching a recorded video of the interview. OUTCOME MEASURES: Pre- and post-seminar questionnaires using a 7-point Likert scale (from 1: strongly disagree to 7: strongly agree) were used to examine the differences in "confidence in ability to handle difficult patients" and "learning motivation to handle difficult patients". The two items examined by both pre- and post-seminar questionnaires, were analyzed by a paired t-test. The residents were also surveyed on their satisfaction with the seminar, acquisition of new knowledge, and impressions and comments (free-text answers). RESULTS: The findings of the questionnaire showed a significant post-seminar increase in confidence (3.1±1.6 to 4.0±1.5 [p<0.01]) and learning motivation (5.3±1.8 to 5.8±1.5 [p<0.01]) as well as high levels of satisfaction (5.8±1.1) with the seminar and acquisition of knowledge (5.7±1.3). Some residents further reported that the seminar led to self-review and was valuable for their future clinical practice. CONCLUSION: Our seminar on how to handle difficult patients was perceived as effective, as evaluated by the questionnaire, despite the short duration of the session. Factors potentially contributing to this effectiveness include the use of actors as SPs and the post-interview debriefing with feedback from the SP, colleagues, and facilitator.

Cardiovascular response during aquatic exercise in patients with osteoarthritis.

OBJECTIVE: To assess the acute cardiovascular response to aquatic exercise in patients with osteoarthritis. DESIGN: Blood pressure (BP) and heart rate (HR) were measured in 13 female patients with osteoarthritis (63.3 +/- 8.4 yrs) during aquatic walking for 40 mins. A double product (DP) value was calculated by multiplying systolic BP by HR to evaluate the workload of the heart. RESULTS: BP and DP increased transiently with a decrease in HR after water immersion. Aquatic walking induced increases in BP, DP, and HR. Furthermore, BP and DP increased sharply with an increase in HR on leaving the water. The mean maximum increases in systolic BP and DP during each process were 23.5 +/- 18.2 mm Hg and 2931.1 +/- 2758.5 mm Hg/min when entering the water, 36.5 +/- 16.5 mm Hg and 4557.2 +/- 3435.1 mm Hg/min during aquatic walking, and 38.5 +/- 18.9 mm Hg and 5132.3 +/- 3228.8 mm Hg/min on leaving the water. CONCLUSIONS: Water immersion, aquatic walking, and the process of leaving the water induced marked increases in BP in patients with osteoarthritis.
