The trend towards specialization in general hospitals has promoted the development of professional and refined medical technology. However, it also brings problems: patients with complex conditions need to seek medical advice across multiple specialties, increasing the difficulty of accessing healthcare and potentially leading to incomplete treatment plans. Therefore, when dealing with undifferentiated diseases, general practitioners (GPs) must take on the responsibility of providing multidisciplinary comprehensive support.

To analyze GPs' understanding and practice regarding multidisciplinary undifferentiated disease treatment (MUD-MDT).

A survey questionnaire targeting MUD-MDT was developed, and distributed to GPs from multiple hospitals nationwide via the General Practice Alliance platform affiliated with the First Affiliated Hospital of Zhejiang University School of Medicine, collecting basic information of GPs, their awareness and practice of undifferentiated diseases (MUD), and multidisciplinary diagnosis and treatment (MDT).

A total of 303 questionnaires were included, with an average age of (38.8±9.2) years; 194 females (64.03%) and 109 males (35.97%). Regarding MUD, 88.78% (269/303) knew about MUD, but only 23.79% (64/269) had participated in related work; the main reason for lack of knowledge was "lack of relevant training" at 76.47% (26/34). For MDT, 91.42% (277/303) were aware of it, 77.26% (214/277) merely knew the basic concept, and only 22.74% (63/277) had participated in related work. In terms of practical implementation, 32.67% (99/303) had implemented MUD, 49.83% (151/303) had implemented MDT, and 20.46% (62/303) had implemented MUD-MDT. There was a high recognition of MUD-MDT among GPs. Differences in MUD awareness among GPs with different professional titles were statistically significant (P<0.05); differences in MDT awareness between genders and education levels were statistically significant (P<0.05); differences in the implementation of MUD-MDT among different genders, working years, and types of affiliated medical institutions were statistically significant (P<0.05). Analyzing the cognitive scores of three groups of GPs who had implemented, not implemented, or were unclear if MUD-MDT was implemented at their units showed no significant difference in all cognitive items (P>0.05).

Although GPs have a certain level of understanding of MUD-MDT, the implementation rate is not high. Despite its application in outpatient clinics, wards, and teaching activities, more efforts are needed to address issues such as inadequate organizational management, lack of standardized procedures, and uneven professional competence among doctors.

综合医院专科细化趋势促进了医疗技术的专业化和精细化发展，但同时也带来了问题，复杂病情患者需在多个专科间求医，增加了就医难度，并可能导致治疗方案不全面。因此，在处理未分化疾病（MUD）时，全科医生需承担起提供多学科综合保障的重任。

分析全科医生对未分化疾病多学科诊疗（MUD-MDT）方面的认知与实践情况。

制订针对MUD-MDT的调查问卷，并依托于浙江大学医学院附属第一医院全科联盟平台，向全国多家医院的全科医生发放问卷，采集全科医生基本情况，以及对MUD、多学科诊疗（MDT）的认知情况和开展情况。

最终纳入303份调查问卷，研究对象平均（38.8±9.2）岁，女194名（64.03%），男109名（35.97%）。对MUD的相关调研情况可见，有88.78%（269/303）的全科医生了解MUD，仅23.79%（64/269）了解并参与过相关工作；不了解MUD的最主要原因是"缺乏相关培训"（76.47%，26/34）。对MDT的相关调研情况可见，有91.42%（277/303）了解MDT，仅了解基本概念的占77.26%（214/277），仅22.74%（63/277）的全科医生了解并参与过相关工作。从实际开展情况可见，已开展MUD的占32.67%（99/303），已开展MDT的占49.83%（151/303），已开展MUD-MDT的占20.46%（62/303）；选择未开展MUD-MDT的共194名。全科医生对MUD-MDT展现出较高的认可度。不同职称全科医生MUD认识度比较，差异有统计学意义（P<0.05），不同性别、教育层次全科医生MDT认识度比较，差异有统计学意义（P<0.05），不同性别、工作年限、所属医疗机构类型全科医生开展MUD-MDT情况比较，差异有统计学意义（P<0.05）。对已开展、未开展及不清楚本单位是否开展MUD-MDT的3组全科医生的认知评分进行分析，结果显示3组医生在所有认知条目上的评分比较，差异均无统计学意义（P>0.05）。

全科医生对MUD-MDT有一定认识，但实施率不高，尽管MUD-MDT已在门诊、病房和教学活动中得到应用，但仍需加大推广力度，以应对组织管理不规范、流程标准化不足以及医生专业素养参差不齐等问题。
