Key issues include a lack of faculty with cross-border teaching capacity, rigid curriculum design, insufficient intercultural support, and weak quality assurance mechanisms. These gaps hinder the alignment between talent development and industry needs. To address this, the study constructs a "four-in-one" Industry-Education-Research (IER) teaching system tailored for cross-border medical education. Methods This study developed and validated the "four-in-one" IER system through a mixed-methods approach, which included: A PRISMA 2020-compliant literature review. Two rounds of Delphi expert consultation. A two-year pilot with 62 international BME students. A multi-dimensional evaluation using five custom assessment tools. Results The resulting "four-in-one" IER-integrated system encapsulates three core elements of cross-border medical education: cross-border collaborative curriculum design, multi-level cross-cultural adaptation, and whole-process quality assurance. It is structured with four interactive core modules, three core competency dimensions, and a formative-summative integrated assessment framework. Pilot results demonstrated that the pilot group outperformed the control group significantly across all key indicators (all P < 0.01): the mean score of professional core courses was 86.7 ± 5.3 versus 75.2 ± 6.1; the professional skill certification pass rate reached 93.8% versus 65.2%; cross-cultural adaptation scores stood at 82.3 ± 4.5 versus 70.5 ± 5.2; the cross-border employment rate was 65.6% versus 33.2%; and satisfaction with cross-border teaching quality was 87.5% versus 62.3%. Conclusions The system effectively addresses core challenges in cross-border BME education, including curriculum, intercultural adaptation, and quality assurance. It offers both a practical solution for reforming transnational medical education and a scalable model for other disciplines. Transnational Medical Education Cross-Border Biomedical Engineering International Graduates Industry-Education-Research Integration Teaching Practice System Cross-Cultural Adaptation Quality Assurance Figures Figure 1 1. Background Biomedical Engineering (BME) is an interdisciplinary field that merges engineering, life sciences, and medicine, playing a pivotal role in advancing modern healthcare and improving public health [ 1 ]. Driven by the globalization of medical education, the emergence of new engineering disciplines, and national strategies such as the Belt and Road Initiative and Healthy China 2030, cross-border BME education has become a vital channel for global health talent mobility and technological collaboration [ 2 ]. China now hosts a large and steadily growing population of international students, with engineering disciplines—particularly BME—being among the most popular due to their strong professional relevance and broad career prospects. The majority of these students come from regions such as Southeast Asia and Africa [ 3 , 4 ]. However, China's cross-border BME education remains at a relatively early stage. A key bottleneck to its high-quality development is a structural mismatch between the existing teaching system and the core requirements of transnational medical education, particularly in terms of scientific program design, targeted cultural adaptation, and standardized quality assurance [ 5 ]. Cultivating high-caliber international BME graduates to drive global health innovation requires three core goals: teaching quality that meets international benchmarks, solid practical application of technical skills, and strong alignment with industrial needs [ 6 ]. A recent survey of BME postgraduate programs found that the vast majority face challenges in effectively nurturing international graduates. Analyses have identified four main shortcomings in the current teaching system [ 7 ]. First, curriculum design often lacks cross-border customization, with a large portion of content being directly adapted from domestic teaching materials with minimal adjustment for the diverse cultural, cognitive, and learning needs of international students [ 8 , 9 ]. Graduates report that the curriculum is frequently misaligned with their home-country professional and clinical standards, as well as with global industry demands and cross-border technical scenarios. For example, only a small fraction of BME courses systematically integrate international medical device regulatory standards or address cross-border circulation norms, far below the level found in leading international programs. Second, cross-cultural support is generally weak. Only a minority of universities have established dedicated cross-cultural counseling centers for international BME students, and the support that is available is often limited to basic language training. There is a lack of targeted guidance on cross-border medical communication norms, cultural differences in clinical practice, and the adaptation of professional ethics [ 10 , 11 ]. A follow-up survey found that many students report difficulties with language and cultural adaptation, which are associated with lower academic performance and a negative impact on the effectiveness of practical learning [ 12 ]. Third, robust quality assurance mechanisms are lacking. Most universities do not have a quality evaluation system specifically designed for cross-border education. Existing evaluation metrics focus almost exclusively on theoretical performance, while critical aspects such as cross-border practical competence, cross-cultural collaborative skills, and adherence to international professional standards are largely neglected [ 13 , 14 ]. Another critical issue lies in the significant gaps in faculty capabilities for cross-border BME teaching. A survey of instructors at key Chinese universities revealed that only a minority have received systematic international teaching training, and many report difficulties in delivering high-quality, full-English professional courses. In multicultural classrooms, a large proportion struggle to manage diverse educational and clinical backgrounds, and only some succeed in integrating global research and cross-border case studies into their teaching. Regarding industry–academia–research (IER) integration, most faculty lack a clear pathway to translate their research into cross-border clinical or industrial applications, and only a small fraction have participated in joint R&D projects with international firms [ 15 ]. Multi-stakeholder participation is also limited, with international enterprises and overseas medical institutions playing only a marginal role in developing teaching cases, and foreign experts being significantly underrepresented in the classroom compared to leading international programs [ 16 ]. These gaps in faculty capabilities, combined with weak collaboration among stakeholders, directly undermine the quality of cross-border BME graduate training [ 17 ]. These challenges are further amplified by the unique nature of BME, which involves a complex “R&D–clinical translation–industrial application” chain, and by the diverse cultural and professional aspirations of international students [ 18 ]. Such diversity extends beyond demographics to a wide range of professional goals, requiring a more tailored approach than the current one-size-fits-all model. IER integration has been shown to effectively bridge the gap between academia and practice in transnational medical education, leading to measurable improvements in cross-border practical competence and employment outcomes [ 19 ]. However, its adoption in China’s international BME programs remains limited, and existing frameworks often lack specific designs for cross-border needs in curriculum, cultural adaptation, and quality assurance. This underscores the need for a targeted IER system that embeds these three core elements, which is essential for overcoming current barriers and advancing high-quality transnational medical education [ 20 , 21 ]. 2. Aim and Objectives Building on the BME value chain—from technology R&D and clinical translation to industrial application—and the diverse cultural backgrounds and individualized learning needs of international BME graduate students in China, this study addresses three core imperatives of transnational medical education: building a rigorous cross-border curriculum, fostering targeted cross-cultural adaptation, and implementing standardized quality assurance. To this end, we develop a “four-in-one” IER-integrated teaching and practice system that is competency-oriented, modular, supported by robust institutional safeguards, and governed by effective quality management. The study pursues three specific objectives. First, to enhance faculty’s three-dimensional cross-border competencies: proficiency in English-medium teaching, the capacity for translational research with cross-border clinical and industrial applications, and the ability to build effective partnerships with global industry. Second, to cultivate graduates’ core cross-border capabilities in professional and technical expertise, cross-cultural collaboration, and transnational innovation and entrepreneurship. Third, to establish a tailored assessment framework for cross-border capacity building and quality assurance in BME graduate education, addressing current shortcomings such as the disconnect between academic theory and cross-border industry needs, insufficient international adaptability among students, and underdeveloped practical teaching, thereby advancing high-quality, internationally aligned transnational medical education. 3. Methods 3.1 Research Design This study employed a sequential mixed-methods design, integrating quantitative and qualitative approaches across four iterative phases: a systematic literature review, Delphi expert consultation, pilot implementation, and multi-dimensional outcome evaluation. This structure ensured that empirical findings from each stage directly informed subsequent stages, creating a cohesive, evidence-based process. 3.2 Phase 1: Systematic Literature Review The review was conducted in line with PRISMA 2020 guidelines [ 22 ]. We searched four databases (Web of Science Core Collection, Scopus, CNKI, and Wanfang Data) from January 2014 to December 2023 using a Boolean search strategy that combined terms for: (Industry-Education-Research integration OR Industry-University-Research collaboration) AND (biomedical engineering education OR bioengineering education) AND (international graduates OR foreign postgraduates) AND (cross-border education OR transnational education) AND (teaching model OR curriculum design). Inclusion criteria: (1) peer-reviewed original research, systematic reviews, or meta-analyses; (2) a focus on IER integration in engineering education; (3) a focus on international BME or related graduate education; and (4) publication in English or Chinese with full text available. Exclusion criteria: (1) conference abstracts, book reviews, or case reports without a formal study design; (2) irrelevant topics or incomplete data; and (3) duplicate publications. Literature Screening and Quality Appraisal Two researchers independently screened literature, extracted data, and assessed quality. Discrepancies were resolved by consensus with a third senior researcher. The initial search returned 3,864 records; 1,247 duplicates were removed using bibliometric software. After title/abstract screening, 2,415 irrelevant records were excluded, leaving 124 for full-text review. Ultimately, 68 studies were included (1.82% inclusion rate, Fig. S1 ). The quality of the 68 original studies was appraised using domain-specific tools: AMSTAR 2 [ 23 ] for systematic reviews and JBI checklists [ 24 ] for original research. The results showed that the majority of both systematic reviews and original studies were of moderate to high quality, with a low overall risk of bias. Thematic Synthesis We conducted a thematic synthesis of the final set of studies to identify core findings on: (1) IER-integrated teaching models in engineering and BME; (2) key characteristics and challenges of international BME graduate education; and (3) design principles for cross-border medical education, including quality assurance, cultural adaptation, and collaborative architecture. This synthesis provided an evidence base and theoretical foundation for the subsequent Delphi expert consultation. 3.3 Phase 2: Delphi Consultation 3.3.1 Expert Selection To ensure comprehensive insight into cross-border BME education, we assembled a 15-member interdisciplinary panel of experts, selected for their representativeness, subject-matter expertise, and institutional authority. The group comprised: BME Education Scholars (4): With over a decade of experience leading national education reform projects. Senior Engineers (4): From leading international BME companies, possessing extensive experience in global industry practices. International Student Management Specialists (4): With over a decade of experience in postgraduate administration and cross-cultural education. Transnational Medical Education Experts (3): With over 15 years in transnational program design and participation in setting international quality standards. The panel's high caliber was reflected in their qualifications: the majority held PhDs, most had international exchange experience, and many had contributed to transnational medical education projects. This composition ensured the necessary rigor and authority for the consultation. 3.3.2 Consultation Process We conducted two rounds of Delphi consultation via Wenjuanxing, a professional online survey platform. The survey design was informed by the preceding literature review. Round 1: A preliminary questionnaire, with a 100% response rate, gathered expert feedback on key components. Experts rated 53 items (20 on the IER system, 15 on faculty competencies, and 18 on outcomes) using a 5-point Likert scale and provided open-ended comments. Round 2: Based on Round 1, the questionnaire was refined. Items were retained only if they met strict criteria for consensus and practicality: an importance mean score of at least 4.2, a feasibility mean of at least 3.8, and a coefficient of variation below 0.18. This round also added indicators for cross-border clinical practice and enhanced alignment with international standards. The response rate remained at 100%. Statistical analysis of all items yielded a Kendall’s W of 0.82 (P < 0.001), indicating a strong level of expert consensus on the system's design and components. 3.4 Phase 3: Pilot Implementation 3.4.1 Setting The pilot was conducted at two universities in Guangdong Province, a major hub for medical device companies. Both institutions have a substantial population of international students and established partnerships with over 20 BME firms, providing an ideal setting for trialing the new teaching model. 3.4.2 Participants To confirm the groups were equivalent at the outset, we used independent samples t-tests and chi-square tests. No significant differences were found between the groups for the following baseline characteristics. These results confirm the baseline equivalence of the two groups, validating the subsequent comparative analysis of the intervention's effects. 3.4.3 Baseline Equivalence To rule out confounding variables, we used independent samples t - tests and chi - square tests to compare the baseline characteristics of the two groups. There were no statistically significant differences between the pilot and control groups in several aspects ( Table S1 ). These results prove that the two groups were equivalent at the baseline, which validates the subsequent comparative analysis of the intervention effects. 3.4.4 Data Collection Instruments We developed and employed a suite of five custom evaluation tools to assess the effectiveness of the “Four-in-One” IER-integrated teaching system: Academic & Professional Performance Record :​A composite measure based on official transcripts and professional certification exam results, assessing mastery of theoretical knowledge and practical skills. Cross-Cultural Adaptation Scale for International Students (CCAS-IS) [ 25 ]:​A validated scale (Cronbach’s α = 0.87) measuring general living, interpersonal, and academic adaptation. Student Satisfaction Survey ( Table S2 ): A self-designed questionnaire evaluating students' satisfaction with teaching quality, curriculum relevance, and campus support services. Faculty Competency Evaluation Form ( Table S3 ): A tool for assessing instructors' ability to teach BME to international students, with a focus on cross-cultural pedagogy and industry integration. Graduate Employment Tracking Survey ( Table S4 ):​A follow-up (at 6 months post-graduation) via questionnaire and phone interview, collecting data on employment status, sector, and location, with a focus on cross-border outcomes. 3.5 Phase 4: Multi-Dimensional Evaluation To verify the effectiveness of the developed IER - integrated teaching practice system, a comprehensive multi - dimensional evaluation system was put into place. This system consisted of five custom - made evaluation tools and combined mixed - methods data analysis. This approach enabled us to capture both quantitative results and qualitative insights across the key dimensions of cross - border BME education. 3.5.1 Student Learning Effect Evaluation The assessment of student learning outcomes was carried out using the BME International Graduates’ Cross - Border Learning Effect Evaluation Table ( Table S5 ). This table integrated student self - evaluation and tutor formative assessment. It comprised 12 evaluation indicators. To better reflect the unique aspects of cross - border education, three additional metrics were added to the original evaluation framework: cross - border practical ability, mastery of international professional regulatory standards, and cross - cultural medical communication ability. In terms of score weighting, student self - evaluation made up 30% of the total score, while tutor evaluation accounted for 70%. This weighting scheme ensured a balanced and objective assessment of the learning effects. The internal consistency of the evaluation table was verified, and it had a Cronbach’s α coefficient of 0.89, which indicated high reliability. 3.5.2 Teaching Process Evaluation The Cross-Border IER-integrated Teaching Process Evaluation Table ( Table S6 ) was administered for anonymous student evaluation of the teaching implementation process. The table contained 12 indicators, with three new metrics tailored to cross-border teaching added to the original set: cross-cultural teaching effectiveness, international standard integration degree, and cross-border educational resource utilization effect. The Cronbach’s α coefficient for this evaluation table was 0.87, confirming good internal consistency and reliability for measuring the quality of the cross-border IER-integrated teaching process. 3.5.3 Teachers’ Ability Evaluation The Cross - Border IER - integrated Teaching Process Evaluation Table ( Table S7 ) was used for an anonymous student evaluation of the teaching implementation process. The table had 14 indicators. Three new metrics, specifically designed for cross - border teaching, were added to the original set: cross - cultural teaching effectiveness, international standard integration degree, and cross - border educational resource utilization effect. The Cronbach’s α coefficient for this evaluation table was 0.87, confirming its good internal consistency and reliability in measuring the quality of the cross - border IER - integrated teaching process. 3.5.4 Cross-Border IER Cooperation Effectiveness Evaluation The assessment of the effectiveness of cross - border industry - education - research (IER) collaboration was carried out using the Cross - Border IER Cooperation Effectiveness Evaluation Table ( Table S8 ). This evaluation adopted a mutual evaluation approach among the core collaboration partners, namely Chinese universities, overseas scientific research institutions, and international BME enterprises. The table consisted of 11 evaluation indicators. To better capture the unique aspects of cross - border IER cooperation, three collaboration - specific metrics were added to the original evaluation system: the effect of cross - border educational resource sharing, the quality of cross - border teaching case development, and the effectiveness of cross - border practical training. The Cronbach’s α coefficient of this table was 0.85, which indicated an acceptable level of internal consistency for evaluating the outcomes of cross - border IER cooperation. 3.5.5 Comprehensive System Effect Evaluation A comprehensive and holistic assessment of the teaching practice system was conducted with the Comprehensive Effect Evaluation Table of the Cross - Border IER - integrated Teaching Practice System ( Table S9 ). The evaluation results were compiled by the university’s teaching management department and then reviewed by third - party transnational medical education experts. This two - step process was designed to ensure the objectivity and authority of the evaluation. The table included 16 comprehensive evaluation indicators. To reflect the characteristics of cross - border education, three system - level metrics were added to the original framework: the effect of cross - cultural adaptation support, the perfection degree of the cross - border teaching quality assurance system, and the cross - border employment promotion effect for graduates. The internal consistency of this comprehensive evaluation tool was excellent, with a Cronbach’s α coefficient of 0.92. 3.6 Data Analysis Quantitative data, which included professional core course scores, professional skill certification pass rates, cross - border employment rates, and cross - cultural adaptation scale scores, were analyzed using IBM SPSS 26.0. For between - group comparisons of continuous variables, independent samples t - tests were employed. When multi - group comparisons were applicable, one - way analysis of variance (ANOVA) was used. Qualitative data, which comprised transcripts from semi - structured interviews, teacher feedback questionnaires, and teaching practice logs, were coded and analyzed through thematic analysis using NVivo 12 software. The inter - coder reliability coefficient reached κ = 0.86, indicating a high level of consistency in qualitative coding. For all statistical tests, a two - tailed P - value of less than 0.05 was considered statistically significant. 4. Results 4.1 System Architecture: The "Four-in-One" IER-Integrated Teaching Practice Model The primary achievement of this study is the development of a tailored “Four-in-One” Industry–Education–Research (IER) integrated teaching and practice system​ for cross-border Biomedical Engineering (BME) graduate education. Designed to address critical gaps identified through a systematic literature review and Delphi expert consultations, the system effectively integrates global educational, industrial, and clinical resources into a cohesive framework. It comprises four interconnected core modules, three clearly defined core competency dimensions, and a unified formative-summative assessment system (Fig. 1 ). 4.1.1 Module 1: Cross-Border Collaborative Architecture Design his module addresses the mismatch between traditional curricula and the goal of cultivating globally competent BME professionals by constructing a rigorous “Three-Level, Three-Dimensional” collaborative curriculum architecture. The system features a clear credit allocation and progressive learning objectives to rebalance theoretical foundations, professional core competencies, and practical application: Level 1: Foundational Courses (25% of total credits) : Delivers core basic courses in medicine and engineering from a comparative international perspective. It emphasizes the standardization of professional terminology and knowledge system compatibility, using human anatomy as an example, which is taught with both English and Latin terms to align with international educational norms. Level 2: Professional Core Courses (40% of total credits) : Focuses on integrating global industry regulatory standards and technical norms. For instance, the Biomaterials course embeds ISO 10993 (Biological evaluation of medical devices) and ASTM international material testing standards, using cross-border case studies to help students master the technical requirements for global BME work. Level 3: Integrated Practice Courses (35% of total credits) : Centers on Project-Based Learning (PBL) jointly developed with international BME enterprises and overseas medical institutions. Students work in groups on real-world projects tailored to their home countries' needs—such as designing a low-cost, portable pulse oximeter for rural Southeast Asian clinics—to contextualize their engineering skills within actual healthcare environments and enhance practical capabilities. 4.1.2 Module 2: Multi-Level Cross-Cultural Adaptation This module embeds cultural competence development throughout the entire training process, moving beyond basic language support to focus on professional acculturation in biomedical engineering. It operationalizes this through two structured mechanisms: Peer Mentoring via Lab Twinning : International students are paired with senior Chinese graduate students to form stable learning partnerships. This supports the transfer of tacit knowledge—such as laboratory norms, safety protocols, academic etiquette, and teamwork conventions—that are rarely addressed in formal courses. Medical Culture Training Workshops : Specialized sessions highlight cultural differences in clinical environments. For example, they contrast the high-patient-volume workflow in Chinese hospitals with service patterns common in Western or African settings. This training is critical for international students during clinical engineering rotations. 4.1.3 Module 3: Cross-Border Practical Teaching Empowerment This module established a “four-in-one” practical teaching platform​ by integrating on-campus resources with international enterprises, domestic hospitals, and overseas research institutions. To enable authentic engagement, the university formed strategic partnerships with 5 international BME companies and 3 overseas research institutions. The system's distinctive features include: Role-Based Internships : Moving beyond passive observation, students in the pilot group assumed substantive roles—such as Junior Regulatory Affairs Assistant and R&D Support Engineer—to gain hands-on experience in cross-border engineering projects. Global Value Chain Integration : Practical projects were intentionally designed to leverage students' cultural and national backgrounds. For example, students assisted Chinese firms in adapting technical documents for product registration in their home countries. This approach transformed cultural background from a potential learning barrier into a distinctive professional advantage [ 16 , 26 ]. 4.1.4 Module 4: Whole-Process Quality Assurance This module established a comprehensive quality assurance (QA) system based on the Plan-Do-Check-Act (PDCA) cycle to support continuous improvement in teaching and learning. Formative Assessment : A digital portfolio was used to document the development of students' professional competencies, reducing reliance on one-time final examinations. Third-Party Evaluation : Industry mentors contributed 30% of the final grade, assessing professional behavior, teamwork, and practical problem-solving ability. This mechanism helped align graduate competencies with real industry needs. 4.2 Effectiveness of Pilot Implementation 4.2.1 Academic Performance and Skill Certification Integrating industrial scenarios and practical tasks into theoretical teaching strengthened students’ understanding and knowledge retention. As shown in Table 1 , the pilot group achieved significantly higher average scores across all core BME courses. The most pronounced difference was in BME Innovation Design, where the pilot group outperformed the control group by nearly 14 points (89.2 vs. 75.3, P < 0.01). Source: Longitudinal pilot study data (2022–2024). Professional certification pass rates provided objective external validation of students’ practical skill acquisition. Eighty-one point two percent (81.2%) of the pilot group successfully passed the International Medical Device R&D Professional Certification, whereas no students in the control group achieved this credential. Similarly, 75.0% of pilot students obtained professional regulatory certifications relevant to their home countries—such as regional medical device registration certifications or clinical engineering practice qualifications—compared to zero students in the control group (P < 0.01). These results demonstrate that the IER-integrated teaching system effectively bridges the gap between academic learning and internationally recognized professional skill standards. Table 1 Comparison of Academic Performance in Core BME Courses Course Name Control Group (n = 30) Mean ± SD Pilot Group (n = 32) Mean ± SD t-value P-value Biomedical Instrumentation 76.4 ± 5.8 85.2 ± 4.9 6.45 < 0.01 Biomaterials & Tissue Eng. 74.8 ± 6.2 86.1 ± 5.1 7.89 < 0.01 Clinical Engineering 72.5 ± 6.5 87.4 ± 4.8 10.22 < 0.01 Medical Image Processing 78.1 ± 5.5 84.9 ± 5.2 4.98 < 0.01 BME Innovation Design 75.3 ± 5.8 89.2 ± 4.1 10.85 < 0.01 Overall Average 75.2 \pm 6.1 86.7 ± 5.3 8.23 < 0.01 4.2.2 Cross-Cultural Adaptation and Cross-Border Capacity Development Data from the Cross-Cultural Adaptation Scale for International Students (CCAS-IS) confirmed that the "Multi-Level Cross-Cultural Adaptation" module significantly alleviated acculturative stress and enhanced adaptive capacity among international BME students (Table 2 ). The control group exhibited only minimal improvement in overall cross-cultural adaptation scores over the study period (Δ= +2.7), while the pilot group achieved a substantial and statistically significant increase (Δ= +13.8, P < 0.01). Qualitative interview data further supported these quantitative findings: pilot students consistently reported feeling "more confident engaging with Chinese faculty and colleagues" and "better able to navigate the implicit norms and conventions of laboratory and clinical settings"—insights that reflect the module’s success in fostering professional acculturation beyond basic language proficiency. Table 2 Pre- and Post-Intervention Cross-Cultural Adaptation Scores (CCAS-IS) Dimension Group Baseline (Year 1) Post-Intervention (Year 2) Change (Δ) General Adaptation Control 67.8 ± 5.3 70.5 ± 5.2 + 2.7 (Score / 100) Pilot 68.5 ± 5.1 82.3 ± 4.5 + 13.8 Academic Adaptation Control 3.2 / 5.0 3.4 / 5.0 + 0.2 (Likert Scale 1–5) Pilot 3.1 / 5.0 4.2 / 5.0 + 1.1 Social Interaction Control 3.0 / 5.0 3.1 / 5.0 + 0.1 (Likert Scale 1–5) Pilot 3.0 / 5.0 4.1 / 5.0 + 1.1 Note: Data derived from pilot implementation statistics. 4.2.3 Cross-Border Employment and Satisfaction Six months after graduation, employment outcomes demonstrated a clear advantage for the pilot group (Table 3 ). Overall Employment: The pilot group achieved a 90.6% employment rate, significantly higher than the control group's 73.3% (χ² = 6.98, P < 0.01). Cross-Border Employment: This rate, defined as working in transnational enterprises, cross-border technical roles, or for Chinese institutions in one's home country, reached 65.6% for the pilot group. This is nearly double the 34.3% rate of the control group (χ² = 10.32, P < 0.01). Employer feedback further validated the IER-integrated training. Hiring managers consistently preferred pilot graduates, citing their proficient understanding of international medical device compliance standards​ and their ability to seamlessly bridge communication gaps between Chinese R&D teams and overseas markets or clinical settings. Table 3 Employment Outcomes 6 Months Post-Graduation Employment Status Control Group (n = 30) Pilot Group (n = 32) Statistical Significance Total Employment Rate 73.3% 90.6% χ 2 = 6.98, P < 0.01 Cross-Border Employment * 34.3% 65.6% χ 2 = 10.32, P 0.05 (NS) Unemployed/Unknown 6.7% 3.1% *Defined as employment in a role requiring transnational coordination (e.g., international sales, regulatory affairs for export) or located in a multinational corporation. 4.2.4 Results of Multi-Dimensional Evaluation An evaluation using five custom, cross-border-focused rubrics demonstrated consistently strong performance by the "four-in-one" IER-integrated teaching model across all key dimensions of cross-border BME education. Average scores across the evaluation domains were as follows: student cross-border learning effect (85.7 ± 4.2), cross-border teaching process quality (86.3 ± 3.8), teachers’ cross-border teaching and IER collaboration ability (84.5 ± 4.5)—representing a 23.5% improvement from the pre-pilot baseline score of 68.2 ± 5.3—cross-border IER cooperation effectiveness (83.2 ± 4.1), and comprehensive system effect (87.1 ± 3.5). All average scores exceeded the 75-point threshold set for satisfactory performance in cross-border medical education evaluation. Two indicators were among the highest-scoring: "cross-cultural adaptation support effect" and "cross-border quality assurance system perfection degree." This confirms the system effectively addresses the core challenges identified in cross-border BME education. Collectively, the findings provide robust evidence of its effectiveness in meeting the key requirements of transnational medical education. 5. Discussion This study developed and validated a targeted IER-integrated teaching system—the “four-in-one” model—for cross-border BME graduate education among international students in China. Using a sequential approach (systematic literature review, Delphi expert consultation, and a two-year pilot), the model addresses a key gap in the literature, where prior IER integration has focused mainly on domestic students or general engineering contexts, with limited attention to the distinct needs of cross-border BME education [ 27 , 28 ]. As a core component of transnational medical education, cross-border BME faces challenges that set it apart from domestic or non-specialized engineering programs, including cross-cultural adaptation barriers, misalignment with international professional and regulatory standards, and insufficient quality assurance for transnational learning [ 29 , 30 ]. Centered on cultivating globally competitive BME talent, the “four-in-one” model integrates four interconnected, mutually reinforcing modules to build a comprehensive cross-border teaching ecosystem. Pilot results confirm its effectiveness in overcoming critical bottlenecks in China’s cross-border BME graduate training, particularly in optimizing curriculum architecture, strengthening cross-cultural adaptability, and embedding process-wide quality assurance aligned with global norms [ 31 ]. Compared with the control group (traditional academic track), the pilot group showed statistically significant improvements across multiple outcomes: academic performance in core BME courses, pass rates for internationally certified professional skills, cross-cultural adaptation (measured by the CCAS-IS), and cross-border employment six months after graduation [ 32 ]. These findings are consistent with prior evidence on the benefits of IER integration in engineering education [ 8 , 33 ], but extend the literature by incorporating two cross-border-specific enhancements: a structured, multi-level cross-cultural support system and a PDCA-based quality assurance framework aligned with international professional standards. Together, these innovations directly address the unique demands of transnational education and enhance the model’s relevance, adaptability, and practical value for cross-border BME—an advance not fully realized in previous IER research [ 34 ]. 5.1 How the IER-Integrated Model Builds International BME Students’ Capacities The success of the “four-in-one” model stems from its holistic, multi-dimensional approach, where four integrated modules work synergistically to develop students' cognitive, practical, cultural, and professional capacities. 5.1.1 Curriculum Redesign: Linking Knowledge, Skills, and Real-World Contexts The model's “three-level” curriculum integrates foundational, professional, and practice-based courses, blending theory, practice, research, and cultural adaptation into a cohesive pathway. It allocates 35% of credits​to integrated practice and embeds cutting-edge industry technologies [ 35 ]. Contextualized Learning: The curriculum is tailored to students' diverse backgrounds. For example, students from Southeast Asia receive targeted training on their home countries' medical device registration norms, ensuring immediate relevance to their future careers [ 36 ]. Project-Based Learning (PBL): Integrated practice courses employ PBL to tackle context-specific, cross-cultural problems. A prime example is the BME Innovation Design course, where multicultural, cross-disciplinary teams create wearable devices for their home countries' healthcare settings, guided by academics, industry engineers, and cultural specialists [ 37 ]. This approach fosters technical expertise, innovative thinking, and crucial cross-cultural communication and teamwork skills [ 38 ]. By anchoring projects in students' home contexts, the curriculum turns cultural diversity into a strength. The result is a learning experience that is both globally relevant and locally actionable, effectively developing globally competent BME professionals. 5.1.2 Multi-Subject Teaching Team Building: Fostering Collaborative Expertise for Cross-Border Education A key strength of the “four-in-one” IER model is its diverse, multi-subject teaching team, which brings together Chinese university faculty, international BME industry experts, overseas research scholars, and cross-cultural specialists. This structure addresses the limitations of traditional, single-institution models by providing the expertise needed to meet the complex demands of cross-border BME education [ 39 ]. This diverse teaching team strengthens the program by integrating varied expertise and perspectives. Its contributions are as follows: Chinese Faculty: Provide academic rigor and systematic knowledge in core BME courses. International Industry Experts: Integrate global talent standards, cutting-edge technologies, and real-world cases into teaching. Overseas Scholars: Guide students in cross-border research, helping align their work with international academic frontiers. Cross-Cultural Specialists: Offer targeted language and cultural support to address students' communication and adaptation challenges. Beyond its composition, the model focuses on enhancing faculty's cross-border capabilities in three key areas—international teaching, research translation, and industry-academia collaboration. Over two years, the average competency score of core teachers in these areas rose by 23.5%, from 68.2 ± 5.3 to 84.5 ± 4.5. This growth was supported by regular international teaching seminars and collaborative workshops that fostered sustained professional development. These outcomes align with research highlighting the value of multi-stakeholder teaching teams in improving the quality and practical relevance of engineering education. However, this study extends the existing literature by tailoring the team structure to the specific needs of cross-border BME. It integrates cross-cultural specialists and emphasizes the development of faculty's own cross-border competencies, rather than focusing solely on domestic industry-academia collaboration. This customization ensures the team can effectively support students' academic, professional, and cultural growth, further enhancing the model's adaptability to transnational education scenarios [ 40 ]. 5.1.3 Practical Platform Construction: Bridging Academia and Global Industrial Practice The four-in-one practical platform is a robust framework designed to bridge the gap between academia and global industrial practice for cross-border BME education. It integrates on-campus resources, international BME enterprises, overseas research institutions, and global medical facilities, directly addressing a key shortcoming in traditional programs where academic training is disconnected from real-world, cross-border professional practice [ 41 ]. On-Campus Laboratories: Equipped to international standards, these provide foundational, hands-on training to master core operational skills aligned with global norms. Off-Campus Practice Bases: Partnerships with international BME enterprises immerse students in real-world industrial scenarios, including production, R&D, and regulatory compliance, helping them understand global role requirements. International Research Platforms: Joint projects with overseas institutions allow students to engage in cross-border scientific research, master international methodologies, and collaborate with global peers on cutting-edge academic frontiers.. his platform directly addresses a key gap in traditional cross-border BME education: the disconnect between academic training and real-world, cross-border professional practice. This platform creates a symbiotic relationship between talent cultivation and the global BME industry. It aligns curricula with the specific competency demands of international partners, while these partners gain access to a pipeline of practice-ready graduates [ 42 ]. These outcomes align with research on IER-based platforms, but this study extends the work by embedding a cross-border focus with overseas partners and contexts, rather than restricting collaboration to domestic entities, ensuring graduates are prepared for cross-border professional roles. 5.1.4 Cross-Cultural Support and Quality Assurance (QA) Mechanism The “four-in-one” model's core strength is its integrated, full-cycle cross-cultural support system combined with a rigorous QA mechanism. This dual-component approach directly addresses the cultural barriers and inconsistent, non-internationally aligned teaching quality found in traditional cross-border BME education. Pre-Admission: Targeted language training and cross-cultural orientation programs equip students with the academic English and cultural knowledge needed to adapt quickly to China's learning and living environment. During Studies: In-school cultural competence courses, one-on-one academic counseling, and a “Lab Twinning” peer mentoring program help students overcome technical communication hurdles, adapt to Chinese teaching methods, and resolve cultural misunderstandings. Post-Graduation: Personalized career guidance and long-term follow-up mechanisms support students in leveraging their cross-cultural and professional skills to integrate into the global BME job market, whether in their home countries, China, or in other transnational roles. This comprehensive support system significantly improved students’ cross-cultural adaptation, as evidenced by a marked rise in their CCAS-IS scores during the pilot. By reducing the negative impact of cultural differences, the model enabled students to fully engage in their studies and IER-integrated projects. These outcomes align with research showing that targeted cross-cultural support enhances academic performance in transnational medical education. Crucially, by embedding this support within a whole-process QA system, the model ensures alignment with international education standards and further strengthens its effectiveness in cross-border contexts. 5.2 Advantages of the Formative-Summative Combined Assessment Framework The formative-summative combined assessment framework is a core component of the model’s whole-process quality assurance system. It addresses the inherent limitations of traditional, summative-only assessments, which focus narrowly on final outcomes and fail to capture the dynamic processes of cross-border learning and cultural adaptation [ 43 ]. Formative Assessment : This component provides continuous, process-oriented evaluation by tracking students' participation in cross-cultural discussions, completion of home-country-specific assignments, performance in international collaborative training, and progress in cross-cultural problem-based learning (PBL) projects. It uses timely feedback from teachers and industry mentors to identify learning gaps and provide targeted support [ 44 ]. Summative Assessment : This component measures students' overall achievement against international BME standards through final exams, industry-recognized skill certifications, and graduation projects that demonstrate cross-cultural application value. By combining these approaches, the framework creates a comprehensive evaluation system. It not only assesses knowledge and skills but also explicitly incorporates cross-cultural adaptation and identity construction as key indicators. Notably, the framework innovatively incorporates cross-cultural adaptation ability and identity construction as key evaluation indicators. This aligns with research on culturally responsive evaluation for international students and ensures the system not only functions as a scientific quality assurance tool for cross-border BME education, but also supports the cultivation of graduates with genuine global competitiveness . 5.3 Comparison with Existing Research and Innovation Points This study introduces three key innovations to the IER-integrated teaching model, specifically designed for cross-border Biomedical Engineering (BME) education: Scenario-specific design : This approach embeds cross-cultural adaptation throughout the curriculum, customizing content and teaching methods for international students. For example, it integrates region-specific medical device regulations, directly addressing their unique learning needs and poor adaptability in traditional programs [ 45 ]. Systematic Quality Assurance : A comprehensive, end-to-end quality assurance system is established, covering teaching inputs, process management, and output evaluation. This system is reinforced by third-party assessments from international industry experts, ensuring training quality meets both international professional standards and industry demands [ 30 ]. Synergistic Collaboration : A four-in-one teaching team and practical platform unite Chinese universities, international enterprises, overseas research institutions, and cross-cultural specialists. This breaks the single-discipline barrier of traditional models and fosters a “education–industry–research” synergy. These innovations shift talent cultivation from a “domestic-oriented” to a “cross-border-oriented” paradigm. By doing so, the model better aligns with the unique characteristics of cross-border BME education and offers a practical solution to its core challenges. 5.4 Limitations and Future Research Directions in Cross-Border Contexts Despite its contributions, this study has several limitations that point to areas for future research. First, its geographical and sample constraints limit generalizability. The pilot was conducted at a single “Double First-Class” university in a region with a dense BME industry cluster and mature international education infrastructure. The relatively small sample of 62 international graduate students, drawn from a setting with strong institutional resources and a particular student profile, may not reflect the diversity of cross-border BME education across China, such as that found in central or western regions with fewer industry–university links or different international student cohorts. Future research should therefore expand to multiple universities in varied geographic and institutional contexts. Second, the employment outcome assessment was limited to a 6-month post-graduation follow-up. While this captures initial employability and cross-border employment trends, it does not reveal the model’s long-term impact on graduates’ career progression, professional advancement, or sustained competitiveness in the global BME industry. Longer-term tracking over 2–5 years is needed to better understand graduates’ career trajectories, leadership roles, contributions to cross-border technical cooperation, and adherence to international standards, thereby providing stronger evidence of the model’s enduring effectiveness [ 46 ]. Third, current curriculum customization addresses broad regional characteristics but lacks the nuance required for specific national contexts. Variations in medical systems, regulatory frameworks, and industrial demands within individual countries may reduce the precision with which the model meets students’ personalized career needs. To address these limitations, future work will focus on refining the “four-in-one” model in three main ways: Enhancing Curriculum Customization Aligning content more closely with the specific medical systems, regulatory requirements, and industrial characteristics of students’ home countries. Accelerating Platform Digitalization Using online collaboration tools and virtual simulations to create more accessible global BME resources for students and faculty, regardless of location. Establishing an International Certification System [ 47 ]: Partnering with international professional organizations to improve the global recognition of Chinese cross-border BME programs and support mutual qualification recognition. 6. Conclusions This study developed and validated a tailored “four-in-one” IER teaching system to address key challenges in cross-border BME graduate education for international students in China. These challenges include the disconnect between academic theory and global industrial practice, insufficient international adaptability, and weak practical teaching. The system is guided by the principles of ability orientation, module integration, institutional guarantee, and effectiveness evaluation. It integrates four synergistic core modules, three targeted competency dimensions, and a formative-summative assessment framework to cultivate technical proficiency, cross-cultural collaboration, and transnational innovation. Future work should expand multi-site pilots to enhance generalizability, refine the curriculum for specific national contexts, digitally upgrade cross-border platforms, and partner with international organizations to explore a global certification system. This system aims to drive high-quality transnational education and cultivate globally competitive BME professionals, ultimately advancing international technical cooperation and the sustainable growth of the biomedical engineering field.

Background","content":" \u003cp\u003eBiomedical Engineering (BME) is an interdisciplinary field that merges engineering, life sciences, and medicine, playing a pivotal role in advancing modern healthcare and improving public health [\u003cspan citationid=\"CR1\" class=\"CitationRef\"\u003e1\u003c/span\u003e]. Driven by the globalization of medical education, the emergence of new engineering disciplines, and national strategies such as the Belt and Road Initiative and Healthy China 2030, cross-border BME education has become a vital channel for global health talent mobility and technological collaboration [\u003cspan citationid=\"CR2\" class=\"CitationRef\"\u003e2\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eChina now hosts a large and steadily growing population of international students, with engineering disciplines\u0026mdash;particularly BME\u0026mdash;being among the most popular due to their strong professional relevance and broad career prospects. The majority of these students come from regions such as Southeast Asia and Africa [\u003cspan citationid=\"CR3\" class=\"CitationRef\"\u003e3\u003c/span\u003e, \u003cspan citationid=\"CR4\" class=\"CitationRef\"\u003e4\u003c/span\u003e]. However, China's cross-border BME education remains at a relatively early stage. A key bottleneck to its high-quality development is a structural mismatch between the existing teaching system and the core requirements of transnational medical education, particularly in terms of scientific program design, targeted cultural adaptation, and standardized quality assurance [\u003cspan citationid=\"CR5\" class=\"CitationRef\"\u003e5\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eCultivating high-caliber international BME graduates to drive global health innovation requires three core goals: teaching quality that meets international benchmarks, solid practical application of technical skills, and strong alignment with industrial needs [\u003cspan citationid=\"CR6\" class=\"CitationRef\"\u003e6\u003c/span\u003e]. A recent survey of BME postgraduate programs found that the vast majority face challenges in effectively nurturing international graduates. Analyses have identified four main shortcomings in the current teaching system [\u003cspan citationid=\"CR7\" class=\"CitationRef\"\u003e7\u003c/span\u003e]. First, curriculum design often lacks cross-border customization, with a large portion of content being directly adapted from domestic teaching materials with minimal adjustment for the diverse cultural, cognitive, and learning needs of international students [\u003cspan citationid=\"CR8\" class=\"CitationRef\"\u003e8\u003c/span\u003e, \u003cspan citationid=\"CR9\" class=\"CitationRef\"\u003e9\u003c/span\u003e]. Graduates report that the curriculum is frequently misaligned with their home-country professional and clinical standards, as well as with global industry demands and cross-border technical scenarios. For example, only a small fraction of BME courses systematically integrate international medical device regulatory standards or address cross-border circulation norms, far below the level found in leading international programs.\u003c/p\u003e \u003cp\u003eSecond, cross-cultural support is generally weak. Only a minority of universities have established dedicated cross-cultural counseling centers for international BME students, and the support that is available is often limited to basic language training. There is a lack of targeted guidance on cross-border medical communication norms, cultural differences in clinical practice, and the adaptation of professional ethics [\u003cspan citationid=\"CR10\" class=\"CitationRef\"\u003e10\u003c/span\u003e, \u003cspan citationid=\"CR11\" class=\"CitationRef\"\u003e11\u003c/span\u003e]. A follow-up survey found that many students report difficulties with language and cultural adaptation, which are associated with lower academic performance and a negative impact on the effectiveness of practical learning [\u003cspan citationid=\"CR12\" class=\"CitationRef\"\u003e12\u003c/span\u003e]. Third, robust quality assurance mechanisms are lacking. Most universities do not have a quality evaluation system specifically designed for cross-border education. Existing evaluation metrics focus almost exclusively on theoretical performance, while critical aspects such as cross-border practical competence, cross-cultural collaborative skills, and adherence to international professional standards are largely neglected [\u003cspan citationid=\"CR13\" class=\"CitationRef\"\u003e13\u003c/span\u003e, \u003cspan citationid=\"CR14\" class=\"CitationRef\"\u003e14\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eAnother critical issue lies in the significant gaps in faculty capabilities for cross-border BME teaching. A survey of instructors at key Chinese universities revealed that only a minority have received systematic international teaching training, and many report difficulties in delivering high-quality, full-English professional courses. In multicultural classrooms, a large proportion struggle to manage diverse educational and clinical backgrounds, and only some succeed in integrating global research and cross-border case studies into their teaching. Regarding industry\u0026ndash;academia\u0026ndash;research (IER) integration, most faculty lack a clear pathway to translate their research into cross-border clinical or industrial applications, and only a small fraction have participated in joint R\u0026amp;D projects with international firms [\u003cspan citationid=\"CR15\" class=\"CitationRef\"\u003e15\u003c/span\u003e]. Multi-stakeholder participation is also limited, with international enterprises and overseas medical institutions playing only a marginal role in developing teaching cases, and foreign experts being significantly underrepresented in the classroom compared to leading international programs [\u003cspan citationid=\"CR16\" class=\"CitationRef\"\u003e16\u003c/span\u003e]. These gaps in faculty capabilities, combined with weak collaboration among stakeholders, directly undermine the quality of cross-border BME graduate training [\u003cspan citationid=\"CR17\" class=\"CitationRef\"\u003e17\u003c/span\u003e].\u003c/p\u003e \u003cp\u003eThese challenges are further amplified by the unique nature of BME, which involves a complex \u0026ldquo;R\u0026amp;D\u0026ndash;clinical translation\u0026ndash;industrial application\u0026rdquo; chain, and by the diverse cultural and professional aspirations of international students [\u003cspan citationid=\"CR18\" class=\"CitationRef\"\u003e18\u003c/span\u003e]. Such diversity extends beyond demographics to a wide range of professional goals, requiring a more tailored approach than the current one-size-fits-all model. IER integration has been shown to effectively bridge the gap between academia and practice in transnational medical education, leading to measurable improvements in cross-border practical competence and employment outcomes [\u003cspan citationid=\"CR19\" class=\"CitationRef\"\u003e19\u003c/span\u003e]. However, its adoption in China\u0026rsquo;s international BME programs remains limited, and existing frameworks often lack specific designs for cross-border needs in curriculum, cultural adaptation, and quality assurance. This underscores the need for a targeted IER system that embeds these three core elements, which is essential for overcoming current barriers and advancing high-quality transnational medical education [\u003cspan citationid=\"CR20\" class=\"CitationRef\"\u003e20\u003c/span\u003e, \u003cspan citationid=\"CR21\" class=\"CitationRef\"\u003e21\u003c/span\u003e].\u003c/p\u003e "},{"header":"2.

However, this study extends the existing literature by tailoring the team structure to the specific needs of cross-border BME. It integrates cross-cultural specialists and emphasizes the development of faculty's own cross-border competencies, rather than focusing solely on domestic industry-academia collaboration. This customization ensures the team can effectively support students' academic, professional, and cultural growth, further enhancing the model's adaptability to transnational education scenarios [\u003cspan citationid=\"CR40\" class=\"CitationRef\"\u003e40\u003c/span\u003e].\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec36\" class=\"Section3\"\u003e \u003ch2\u003e5.1.3 Practical Platform Construction: Bridging Academia and Global Industrial Practice\u003c/h2\u003e \u003cp\u003eThe four-in-one practical platform is a robust framework designed to bridge the gap between academia and global industrial practice for cross-border BME education.

Key issues include a lack of faculty with cross-border teaching capacity, rigid curriculum design, insufficient intercultural support, and weak quality assurance mechanisms. These gaps hinder the alignment between talent development and industry needs. To address this, the study constructs a \"four-in-one\" Industry-Education-Research (IER) teaching system tailored for cross-border medical education.\u003c/p\u003e\u003ch2\u003eMethods\u003c/h2\u003e \u003cp\u003eThis study developed and validated the \"four-in-one\" IER system through a mixed-methods approach, which included: A PRISMA 2020-compliant literature review. Two rounds of Delphi expert consultation. A two-year pilot with 62 international BME students. A multi-dimensional evaluation using five custom assessment tools.\u003c/p\u003e\u003ch2\u003eResults\u003c/h2\u003e \u003cp\u003eThe resulting \"four-in-one\" IER-integrated system encapsulates three core elements of cross-border medical education: cross-border collaborative curriculum design, multi-level cross-cultural adaptation, and whole-process quality assurance. It is structured with four interactive core modules, three core competency dimensions, and a formative-summative integrated assessment framework. Pilot results demonstrated that the pilot group outperformed the control group significantly across all key indicators (all P\u0026thinsp;\u0026lt;\u0026thinsp;0.01): the mean score of professional core courses was 86.7\u0026thinsp;\u0026plusmn;\u0026thinsp;5.3 versus 75.2\u0026thinsp;\u0026plusmn;\u0026thinsp;6.1; the professional skill certification pass rate reached 93.8% versus 65.2%; cross-cultural adaptation scores stood at 82.3\u0026thinsp;\u0026plusmn;\u0026thinsp;4.5 versus 70.5\u0026thinsp;\u0026plusmn;\u0026thinsp;5.2; the cross-border employment rate was 65.6% versus 33.2%; and satisfaction with cross-border teaching quality was 87.5% versus 62.3%.\u003c/p\u003e\u003ch2\u003eConclusions\u003c/h2\u003e \u003cp\u003eThe system effectively addresses core challenges in cross-border BME education, including curriculum, intercultural adaptation, and quality assurance. It offers both a practical solution for reforming transnational medical education and a scalable model for other disciplines.\u003c/p\u003e","manuscriptTitle":"Integration of Industry-Education-Research for Cross-Border Biomedical Engineering Graduate Education: Architecture Design, Local Adaptation, and Quality Assurance","msid":"","msnumber":"","nonDraftVersions":[{"code":1,"date":"2026-03-13 09:27:50","doi":"10.21203/rs.3.rs-8936779/v1","editorialEvents":[{"type":"communityComments","content":0},{"type":"reviewersInvited","content":"","date":"2026-03-11T05:34:23+00:00","index":"","fulltext":""},{"type":"editorAssigned","content":"","date":"2026-02-27T05:42:45+00:00","index":"","fulltext":""},{"type":"checksComplete","content":"","date":"2026-02-27T04:01:30+00:00","index":"","fulltext":""},{"type":"submitted","content":"BMC Medical Education","date":"2026-02-27T02:52:27+00:00","index":"","fulltext":""}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"bmc-medical-education","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":false,"externalIdentity":"meed","sideBox":"Learn more about [BMC Medical Education](http://bmcmededuc.biomedcentral.com/)","snPcode":"","submissionUrl":"https://www.editorialmanager.com/meed/default.aspx","title":"BMC Medical Education","twitterHandle":"BMC_series","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"em","reportingPortfolio":"BMC Series","inReviewEnabled":true,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"3dbfc2d7-f191-40c7-a133-41094361b19a","owner":[],"postedDate":"March 13th, 2026","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"under-review","subjectAreas":[],"tags":[],"updatedAt":"2026-03-13T09:27:50+00:00","versionOfRecord":[],"versionCreatedAt":"2026-03-13 09:27:50","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v1","identity":"rs-8936779","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-8936779","identity":"rs-8936779","version":["v1"]},"buildId":"XKTyCvWXoU3ODBz1xrDgd","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
