Objective:To construct a set of scientific, oriented, and feasible teaching evaluation indices for undergraduate clinical medicine teaching that are suitable for the development and needs of clinical teaching.Methods:A preliminary index system was established based on literature search, semi-structured interview, and group discussion, and then a consultation questionnaire was compiled to conduct two rounds of consultation with 25 Chinese experts. SPSS 27.0 software was used for statistical analysis.Results:The questionnaire recovery rate was 100.0% for both rounds of consultation, indicating the highly active participation of experts. The authority coefficient of experts was >0.84, indicating a high degree of reliability. The coefficient of variation was 0-0.22 for each index, and the coordination coefficient of the second round was higher than that of the first round ( P<0.001), indicating a relatively high degree of coordination of expert opinions and relatively credible results of the consistency of expert opinions. Finally a set of quality assessment indices were developed for theoretical lectures, clinical teaching, and online theoretical courses for undergraduate medical students, including 6-7 primary indices and 12-14 secondary indices. Conclusions:Through the scientific and standardized application of the Delphi method, a set of comprehensive undergraduate teaching evaluation indices with clinical characteristics have been developed, which can adapt to the development of the new era, improve the quality of teaching, and promote the development of medical talents.

Objective:To conduct a nationwide physician survey to better understand clinicians’ disease awareness, treatment patterns, and experience of Waldenstr?m macroglobulinemia (WM) in China.Methods:This cross-sectional study was conducted from February 2022 to July 2022 by recruiting clinicians with WM treatment experience from hematology, hematology-oncology, and oncology departments throughout China. Quantitative surveys were designed based on the qualitative interviews.Results:The study included 415 clinicians from 219 hospitals spread across thirty-three cities and twenty-two provinces. As for diagnosis, the laboratory tests prescribed by physicians for suspected WM patients were relatively consistent (92% -99% recommendation for laboratory, 79% -95% recommendation for pathology, 96% recommendation for gene testing, and 63% -83% recommendation for imaging examination). However, from a physician's perspective, there was 22% misdiagnosis occurred in clinical practice. The rate of misdiagnosis was higher in lower-level hospitals than in tertiary grade A hospitals (29% vs 21%, P<0.001). The main reasons for misdiagnosis were that WM was easily confused with other diseases, and physicians lacked the necessary knowledge to make an accurate diagnosis. In terms of gene testing in clinical practice, 96% of participating physicians believed that WM patients would require gene testing for MYD88 and CXCR4 mutations because the results of gene testing would aid in confirming diagnosis and treatment options. In terms of treatment, 55% of physicians thought that the most important goal was to achieve remission, while 54% and 51% of physicians wanted to improve laboratory and/or examination results and extend overall survival time, respectively. Among patients with treatment indications, physicians estimated that approximately 21% of them refused to receive treatment, mainly owing to a lack of affordable care and disease awareness. When selecting the most appropriate treatment regimens, physicians would consider patient affordability (63% ), comorbidity (61% ), and risk level (54% ). Regimens containing Bruton tyrosine kinase inhibitor (BTKi) were most widely recommended for both treatment-na?ve and relapsed/refractory patients (94% for all patients, 95% for treatment-na?ve patients, and 75% for relapsed/refractory patients), and most physicians recommended Ibrutinib (84% ). For those patients who received treatment, physicians reported that approximately 23% of patients did not comply with the treatment regimen due to a lack of affordability and disease awareness. Furthermore, 66% of physicians believe that in the future, increasing disease awareness and improving diagnosis rates is critical. Conclusions:This study is the first national physician survey of WM conducted in China. It systematically describes the issues that exist in WM diagnosis and treatment in China, such as a high rate of misdiagnosis, limited access to gene testing and new drugs, and poor patient adherence to treatment. Chinese doctors believe that improving doctors’ and patients’ understanding of WM is one of the most urgent issues that must be addressed right now.

ObjectiveTo investigate rehabilitation competence among trainers and trainees whom participated in the training program entitled National Training Program of Shortage Rehabilitation Physicians (NTPSRP) using World Health Organization rehabilitation competency framework (RCF). MethodsBased on RCF, a questionnaire was developed and administrated through network using Questionnaire Star. All the trainers and trainees who participated in NTPSRP were investigated in September, 2023. ResultsA total of 911 subjects were collected from 27 provinces, including 426 trainers (teachers) and 485 trainees (students). The average age of the teachers was older, with more years of work experience and professional experience in rehabilitation medicine. The degree and professional title of the teachers was also higher. The overall internal consistency reliability of the questionnaire was good (Cronbach's α = 0.988), and all the internal consistency reliability in five fields was good (Cronbach's α > 0.9). The five dimensional structure of RCF in the results was consistent with the prior model established by RCF theory. The self-ratings of all physicians in the five fields were higher than the median level, and was higher in the teachers than in the students [(3.42±0.68) vs. (2.73±0.80), P < 0.001]. Gender and years of experience in rehabilitation medicine were independent factors for the total score of the questionnaire. The total self-rating of female students was 9.65 points lower than that of the male (95%CI 4.386 to 14.914); and one more year in rehabilitation medicine would increase 1.78 points in self-rating (95%CI 1.140 to 2.419). ConclusionThe structure and content of RCF can be used to evaluate the competence of rehabilitation physicians. The teachers and students of NTPSRP are eligible to RCF. RCF-based evaluation can be used to guide the development of continuing education courses for rehabilitation professionals.

Objective:To systematically identify and summarizes the weaknesses of the key aspects of Investigator-Initiated Clinical Trial (IIT) quality management in China, and quantitatively assess these weaknesses with a synthesis of relevant evidence, thereby providing references for the subsequent establishment of a complete IIT quality management system in China.Methods:According to the Scoping review report checklist (PRISMA-ScR statement), we conducted a systematic literature retrieval and screening, data extraction, and result synthesis of IIT quality management issues after defining the research questions.Results:73 eligible studies were eventually included. It was found that the most frequently explored issues were a lack of guidance and support from methodological and statistical experts at the project initiation stage (60.9%), a lack of research funding or improper funding management at the project implementation stage (49.3%), mismanagement of archival materials at the project completion stage (70.0%). Meta-analysis results showed that after evidence synthesis, the incidence of irregular informed consent signing, untraceable raw data, delayed study progress, and protocol violation were all above 40%, but there was heterogeneity in the results.Conclusion:Some outstanding issues in IIT quality management need to be addressed. Future studies should conduct more practical research to obtain quantitative data, undertake demonstrative application of management protocols, further carry out pioneering exploration and research in the field of IIT quality management, and propose effective solutions and strategies to improve IIT quality.

ObjectiveTo evaluate the Chinese guidelines and consensus of rehabilitation medicine published in the medical journals in 2022 using Scientific, Transparent and Applicable Rankings (STAR). MethodsGuidelines and consensus which were developed by Chinese institutions or led by Chinese scholars were retrieved in databases of CNKI, Wanfang Data, CBM, Chinese Medical Journal Network, PubMed and Web of Science, in 2022, followed by screening for rehabilitation medicine field. The literature were rated with STAR. ResultsSeven guidelines and eleven consensuses were included. The STAR scores ranged from 11.7 to 69.6, with a median score of 25.9 and mean score of 28.3. There was a significant difference in the total score between guidelines and consensus (U = 12.000, P = 0.014). The score ratio was high in the domains of recommendations (73.6%), evidence (39.5%) and others (33.3%), while it was low in the domains of protocol (1.4%), clinical questions (12.5%) and conflicts of interest (13.9%). The score ratio was high in the items of listing the institutional affiliations of all individuals involved in developing the guideline (94.4%), identifying the references for evidence supporting the main recommendations (94.4%), indicating the considerations (e.g., adverse effects) in clinical practice when implementing the recommendations (88.9%), and making the recommendations clearly identifiable, e.g., in a table, or using enlarged or bold fonts (75%); and it was low in the items of describing the role of funder(s) in the guideline development (0), indicating information about the evaluation and management of conflicts of interest (0), providing tailored editions of the guidelines for different groups of target users (0), presenting the guideline or recommendations visually, such as with figures or videos (0), providing details of the guideline protocol (2.8%), assessing the risk of bias or methodological quality of the included studies (2.8%), describing the responsibilities of all individuals or sub-groups involved in developing the guideline (5.6%), indicating how the clinical questions were selected and sorted (5.6%), formating clinical questions in PICO or other formats (5.6%), making the guideline accessible through multiple platforms (5.6%), and declaring that the funder(s) did not influence the guideline's recommendations (8.3%). ConclusionThe quality of current clinical practice guidelines and consensus of rehabilitation medicine is poor, which should be developed in accordance with the relevant standards.

Objective: Based on a qualitative research method, the present study aims to explore the negative experiences and real dilemmas of adolescent with depression in the treatment and rehabilitation process, so as to provide references to promote the improvement of the treatment system for adolescent depression in China. Methods: From August 2022 to November 2022, 30 adolescents with depression were selected for in-depth interviews in the inpatient department of child and adolescent psychiatry at Beijing An Ding Hospital affiliated with Capital Medical University by using the purposive sampling method, and the interview data were analyzed by using the Colaizzi method to summarize the themes. Results: The real dilemmas faced by depressed adolescent during treatment and recovery included three aspects:inappropriate family coping (caregivers lacking of correct disease cognition; caregivers lacking of effective coping methods), difficulties in disease diagnosis and treatment (low rate of identification and adverse effect of treatment; medical service failing to satisfy the demands), and barriers to continued schooling (barriers to academic progress and interpersonal communication). Conclusion Adolescents with depression face real dilemmas in the process of disease treatment and rehabilitation at home, school and medical care. Caregivers disease literacy and caregiving skills should be improved. A collaborative disease management system among family, school, community and medical institutions should be established to promote adolescent depression treatment and social function recovery.

Objective:To investigate the early clinical effects of home-based mobile health intervention on knee joint function after anterior cruciate ligament (ACL) reconstruction.Methods:This was a prospective randomized controlled trial. Patients undergoing arthroscopic ACL reconstruction alone at the Institute of Sports Medicine, Peking University Third Hospital from April 2019 to December 2019 were elected in the trial. Patients were divided into the intervention group and the control group according to random number method. The control group only received the guidance of the traditional paper rehabilitation schedule, while the intervention group also received personalized guidance of electronic rehabilitation prescription and follow-up notice delivered by a WeChat Mini Program Rehabilitation Cloud Platform in addition to the traditional guidance. Joint range of motion (ROM), visual analogue scale (VAS) and thigh circumference difference were assessed before and after the operation. Independent sample t test or Mann-Whitney U test was used for comparison of data between groups, and chi-square test was used for comparison of enumeration data. Results:One hundred and twenty five patients were enrolled in the trial, including 99 males and 26 females, with an average age of 29.0 years (range:18 to 45 years) and an average body mass index of 24.8 kg/m 2 (range:15.8 to 36.6 kg/m 2). At 6 weeks, follow-up was available in 106 cases the target-reach rate of ROM in control group was 42.6%(23/54), which was 67.3%(35/52) in the intervention group, the difference was statistically significant (χ 2=6.53, P=0.01); VAS of the intervention group was 2.5(2.0), lower than that of the control group 3.0(2.0)( M( Q R)), the difference was statistically significant ( Z=-2.06, P=0.04); And the thigh circumference difference of the intervention group was 2.0(2.0)cm lower than that of the control group 3.0(1.8)cm, the difference was statistically significant ( Z=-3.00, P<0.01). Conclusion:Mobile health intervention can improve the early postoperative rehabilitation effect after ACL construction and the ROM of the knee joint, and reduce the bent-knee pain along with the thigh circumference difference.

Objective: To evaluate the feasibility and safety percutaneous pulmonary vein intervention in patients with severe pulmonary vein stenosis (PVS) caused by fibrosing mediastinitis(FM). Methods: This retrospective analysis included 5 FM patients (2 male, 3 female, 54-77 years old) confirmed by clinical presentation and chest computed tomography (CT) scan from January to June 2018 who were from Gansu Provincial Hospital and Shanghai Chest Hospital. CT pulmonary angiography (CTPA) further revealed severe PVS caused by fibrotic tissue compression in mediastinum. After selective pulmonary vein angiography, gradually balloon angioplasty was used to expand the pulmonary vein and then stents were implanted in the pre-dilated stenotic pulmonary veins. Evaluation of therapeutic effect was made at 6 months after the procedure. Results: All of 11 serious compression PVS were treated with stent implantation (diameter: 7-10 mm, length: 17-27 mm). After stenting, degree of pulmonary vein stenosis decreased from (83±16)% to (12±4)% (P<0.01). The minimal diameter of the stenotic pulmonary vein was significantly increased from (0.8±0.5)mm to (7.5±0.8)mm (P<0.01). Trans-stenotic gradient decreased from (27.0±15.1)mmHg (1 mmHg=0.133 kPa) to (2.50±0.58)mmHg (P<0.05). Mean pulmonary pressure measured by cardiac catheter decreased from (45.0±9.0)mmHg to (38.7±8.4)mmHg (P<0.05). One patient experienced cardiac arrest due to vagal nerve reflex during big sizing balloon stent dilation and recovered after cardiopulmonary resuscitation. There were no other serious procedure related complications. During the follow-up, severe stenosis at end of proximal stent was evidenced in 1 patient due to fibrotic compression, and another patient developed in-stent thrombosis due to discontinuation of prescribed anticoagulant. Conclusion Percutaneous intervention for severe pulmonary vein stenosis caused by FM is feasible and safe, and can improve hemodynamic caused by the compression of mediastinal vascular structures in these carefully selected patients.
