BACKGROUND: Auscultation is a simple physical examination that provides important clinical information. Many educational materials are available to facilitate students' understanding of lung auscultation. Some studies and teaching materials have visualized lung sounds as spectrograms. However, their effectiveness as educational tools remains unclear. Accordingly, this study evaluates the effect of auscultation education using lung sound visualization on medical students' diagnostic skills. METHODS: Participants were medical students completing their four-week clinical clerkship (CC) in the Department of Respiratory Medicine of Chiba University Hospital. Sixty-three students participated in this study between November 2022 and July 2023. They were divided into two groups: the full-term visualization group (n = 31) and the half-term visualization group (n = 32). Although both groups were taught lung sound visualization using simple diagrams, there was a two-week difference in the length of exposure. We taught visualization to the full-term visualization group on the first day of the CC, and to the half-term visualization group after the midpoint test. Thus, the full-term visualization group practiced lung auscultations with visualization for four weeks, while the half-term visualization group had two weeks of practice. All the students performed lung auscultation tests with a simulator three times: pre-test at the beginning, midpoint at the end of the second week, and post-test at the end of CC. In addition, they responded to questionnaires regarding lung auscultation at the beginning and end of CC. RESULTS: The score gain from baseline in the lung auscultation tests at the midpoint was 0.5; p = 0.018). The increase in scores at the post-test was not significantly different between the two groups (median full-term, + 3.6; half-term, + 2.3; p = 0.060). The self-reported confidence, clinical reasoning ability, activity, and frequency of lung auscultation improved in both groups. The questionnaire responses indicated that the students accepted the value of lung sound visualization. CONCLUSIONS: Differing the duration of exposure to lung sound visualization (two weeks and four weeks) showed no significant difference in medical students' auscultation skills.

BACKGROUND: Japan faces a health care delivery challenge due to physician maldistribution, with insufficient physicians practicing in rural areas. This issue impacts health care access in remote areas and affects patient outcomes. Educational interventions targeting students' career decision-making can potentially address this problem by promoting interest in rural medicine. We hypothesized that community-based problem-based learning (PBL) using real-patient videos could foster students' understanding of community health care and encourage positive attitudes toward rural health care. OBJECTIVE: This study investigated the impact of community-based PBL on medical students' understanding and engagement with rural health care, focusing on their knowledge, skills, and career orientation. METHODS: Participants were 113 fourth-year medical students from Chiba University, engaged in a transition course between preclinical and clinical clerkships from October 24 to November 2, 2023. The students were randomly divided into 16 groups (7-8 participants per group). Each group participated in two 3-hour PBL sessions per week over 2 consecutive weeks. Quantitative data were collected using pre- and postintervention questionnaires, comprehension tests, and tutor-assessed rubrics. Self-assessment questionnaires evaluated the students' interest in community health care and their ability to envision community health care settings before and after the intervention. Qualitative data from the students' semistructured interviews after the PBL sessions assessed the influence of PBL experience on clinical clerkship in community hospitals. Statistical analysis included median (IQR), effect sizes, and P values for quantitative outcomes. Thematic analysis was used for qualitative data. RESULTS: Of the 113 participants, 71 (62.8%) were male and 42 (37.2%) female. The total comprehension test scores improved significantly (pretest: median 4.0, IQR 2.5-5.0; posttest: median 5, IQR 4-5; P<.001; effect size r=0.528). Rubric-based assessments showed increased knowledge application (pretest: median 8, IQR 7-9; posttest: median 8, IQR 8-8; P<.001; r=0.494) and self-directed learning (pretest: median 8, IQR 7-9; posttest: median 8, IQR 8-8; P<.001; r=0.553). Self-assessment questionnaires revealed significant improvements in the students' interest in community health care (median 3, IQR 3-4 to median 4, IQR 3-4; P<.001) and their ability to envision community health care settings (median 3, IQR 3-4 to median 4, IQR 3-4; P<.001). Thematic analysis revealed key themes, such as "empathy in patient care," "challenges in home health care," and "professional identity formation." CONCLUSIONS: Community-based PBL with real-patient videos effectively enhances medical students' understanding of rural health care settings, clinician roles, and the social needs of rural patients. This approach holds potential as an educational strategy to address physician maldistribution. Although this study suggests potential for fostering positive attitudes toward rural health care, further research is needed to assess its long-term impact on students' career trajectories.

BACKGROUND: Report writing in class provides basic training for academic writing. However, report writing education in medical schools in Japan has rarely been reported and no teaching strategy has been established for it. METHODS: This study developed a report writing program using peer review for first-year medical students consisting of two 120-minute classes. The goal of being able to write reports appropriately was established and presented to students at the beginning of the program. In session 1, students decided on a topic, gathered information, and structured their report. In session 2, students' written reports were peer reviewed. The reports were improved based on the peer reviews. The responses of the pre- and post-program questionnaires were evaluated to determine the program's effectiveness. The other reports that were assigned one month after the program were used as comparison with the reports of students who did not participate. Furthermore, the long-term effects of the program were also evaluated by comparing the results of students from the previous year who did not participate in the program with those of program participants six months after the program. RESULTS: A total of 106 students completed the questionnaire evaluation. The program was rated as being acceptable for the students. Self-assessment of report writing significantly improved after the program. The report scores of program participants (n = 99) were significantly higher overall and in all domains than were those of non-participants (n = 99). The self-assessment of students who participated (n = 96) was significantly higher than that of non-participants (n = 109). No difference was observed for students' sense of burden in report writing. CONCLUSIONS: The report writing skills of medical students can be improved by clearly establishing the goals of report writing and practicing the basic skills of report writing step-by-step. Moreover, the use of peer review may enhance the effectiveness of learning opportunities for report writing.

Abstract Background Hidden curriculum (HC) can limit the effects of professionalism education. However, the research on how HC triggers unprofessional behavior among medical students is scant. Furthermore, there is no established approach for how faculty members may create a context, such as an educational environment and education system, that prevents students’ unprofessional behavior. This study aimed to develop an educational approach to prevent unprofessional behavior and clarify how faculty members consider HC that triggers students’ unprofessional behavior. Methods The study sample comprised 44 faculty members and eight medical students from the Chiba University School of Medicine. The participants were divided into groups and asked the following question: “What attitudes, statements, and behaviors of senior students, physicians, and faculty members trigger medical students’ unprofessional behavior?” The responses were collected using the affinity diagram method. The group members discussed the causes and countermeasures for the selected attitudes, statements, and behaviors of senior students, physicians, and faculty members based on the affinity diagram. The impact of the group work on the faculty members was surveyed using questionnaires immediately after its completion and six months later. Furthermore, the cards in the group work were analyzed using content analysis. Results The responses to the questionnaire on group work indicated that some faculty members (43.8%) improved HC, while others suggested conducting group work with more participants. The content analysis revealed six categories – inappropriate attitude/behavior, behavior encouraging unprofessional behavior, lack of compliance with regulations, harassment of other medical staff, inappropriate educational environment/supervisor, and inappropriate self-control – and 46 subcategories. Conclusions The HC that triggers students’ unprofessional behavior includes the words and actions of the educator, organizational culture, and educational environment. Group work makes faculty members aware of the HC that triggers unprofessional behavior, and induces behavioral change for HC improvement in the educational activities. Educators should refrain from using words and actions that encourage unprofessional behavior, such as personal anecdotes, as they reduce students’ learning motivation.
