  • A realist evaluation of community-engaged learning for health professions students in rural Japan: explaining learning processes associated with cultural humility and professional reorientation

    Haruta J., Etsuko

    Advances in Health Sciences Education  2026

    ISSN  13824996

    　View Summary

    Community-engaged learning (CEL) has gained attention in health professions education, yet there remains limited explanatory understanding of how it generates learning processes in East Asian contexts characterized by hierarchical professional cultures. This study used realist evaluation to examine a two-week rural community diagnosis practicum involving Japanese medical, nursing, and pharmacy students. Data were collected through ethnographic fieldwork, students’ written reflective reports, and ten focus group interviews conducted in 2023 and 2024. Analysis identified five key context–mechanism–outcome (CMO) configurations explaining how learning unfolded under specific conditions. These included disruption of perceived “correctness” through lived community encounters, reframing deficit-oriented assumptions about resources through community storytelling, adaptive learning across institutional boundaries, reconsideration of urban-centric career values, and dialogic engagement enabled by students’ non-expert and outsider positioning. Across configurations, learning was generated when contextual conditions disrupted certainty and loosened institutional scripts, activating mechanisms of reflexive reappraisal, adaptive sense-making, and relational openness. These mechanisms contributed to outcomes such as increased epistemic humility, reorientation of professional assumptions, and heightened sensitivity to relational and contextual dimensions of care. Importantly, the uncertainty and ambiguity inherent in CEL functioned not as limitations but as conditions that enabled these learning processes to occur. By specifying how, why, and under what conditions CEL operated in this setting, the study offers a mechanism-focused explanation of learning in hierarchical and collectivist contexts. Findings from rural Japan highlight the theoretical transferability of these explanations and provide guidance for the design and evaluation of CEL initiatives in other sociocultural settings.

    　View Summary

    To assess the relationship between polydoctoring and patient outcomes, we conducted a retrospective cohort study using a Japanese population-based dataset from April 2014 to December 2022. Overall, 2,338,965 patients aged 75-89 years with at least two chronic conditions were included. Polydoctoring was assessed by the number of regularly visited facilities (RVFs). The primary outcome was all-cause mortality, with secondary outcomes being all-cause hospitalizations, hospitalizations for ambulatory care-sensitive conditions (ACSCs), and outpatient costs. During the study period, 14.5% of participants died, 52.2% were hospitalized, and 12.5% experienced ACSC-related hospitalizations. Patients without RVFs had the highest mortality risk (HR: 3.23, 95% CI: 3.14-3.33), while those with ≥ 5 RVFs had the lowest (HR: 0.67, 95% CI: 0.62-0.73). ACSC-related hospitalizations were U-shaped, with increased risk at ≥ 5 RVFs (HR: 1.13, 95% CI: 1.06-1.22). Outpatient costs increased 3.21 times for ≥ 5 RVFs compared to 1 RVF. Polydoctoring was associated with reduced mortality but higher hospitalization rates and costs, with an optimal RVF range of 2-3 which minimized ACSC-related admissions. These findings emphasize the need for strategies that balance the benefits and costs of polydoctoring to support sustainable healthcare through improved care coordination and resource management for aging populations.

  • The ecology of time: Beyond efficiency and outcomes in medical education-reclaiming temporal diversity

    J Haruta

    Medical Teacher, 1-3    1 - 3 2026

    ISSN  0142159X

    　View Summary

    Contemporary medical education is increasingly dominated by the imperatives of efficiency, measurable outcomes, and technological optimization. While these frameworks aim to improve educational quality, they risk marginalizing essential but non-linear learning experiences. This commentary introduces the concept of “temporal diversity” as a necessary ecological shift in curriculum design. By situating the obsession with efficiency within the broader context of New Public Management and social acceleration, we argue for legitimizing “slow time”—relational, reflective, and unstructured moments. Reclaiming temporal diversity is vital for fostering professional identity formation, preventing burnout, and ensuring a humane foundation for medical education.

  • Community Diagnosis for Interprofessional Education in Medical Education

    Murakami Taro, Nagata Minori, Haruta Junji, Tsubota Yuya, Inoue Mari, Akiyama Sakina, Sekiguchi Kao, Harada Rina

    An Official Journal of the Japan Primary Care Association (JAPAN PRIMARY CARE ASSOCIATION)  48 ( 4 ) 132 - 136 2025.12

    ISSN  2185-2928

    　View Summary

    <p>Keio University conducted practical training based on community diagnosis as part of an interprofessional education program involving three healthcare faculties: the School of Medicine, the Faculty of Nursing and Medical Care, and the Faculty of Pharmacy. This training took place in Wakkanai City (Hokkaido), Minakami Town (Gunma), and Mino City (Gifu). Students engaged in data collection, hypothesis setting, fieldwork-based hypothesis verification, and explored solutions to community issues. Through this process, they learned about the importance of experiencing residents' daily lives firsthand, the interconnectedness of various community factors, and collaborative approaches to problem-solving. The program offered students the opportunity to understand community dynamics and teamwork, while engaging in active trial-and-error learning that fostered independent learning and problem-solving skills.</p>
