Objective To better understand the working and learning status of professional degree postgraduates and residents under the combined training mode, so as to provide basis and reference for the formulation of relevant policies of the state and Beijing. Methods A cross-sectional survey was conducted among 476 trainees in 20 training bases of Beijing from July to August 2019. The survey contents include: baseline information such as gender and age, training information such as university, training base, training period, working and learning state information such as working time, duty times, and leave regulations, satisfaction with base management, welfare treatment and value realization,physical and mental conditions such as learning pressure, work demand and ownership feeling. Statistical description method was used for analysis. Results Under the combined training mode, the trainees have long working hours[only 3.2% (15/476) worked less than 40 hours per week], many times on duty[69.7% (332 / 476) were on duty more than three times a month], and the average value of working and learning pressure has reached 74.06; 85.7% (408 / 476) of the trainees agreed or basically agreed that the tutor provided them with the opportunity to increase their new experience and growth through various ways, and 76.5% (364 / 476) of the trainees agreed or basically agreed that the training would be helpful to their actual ability improvement; the mode was approved by master degree and resident doctors, and 78.2% (372 / 476) would still choose the mode if they had the opportunity to choose again, However, it is generally believed that the salary is relatively low, and social insurance, base welfare and vacation arrangement can not meet the demand. Conclusions The trainees are satisfied with the combined training mode, but they are more aware of their work intensity and pressure, less satisfied with their salary and welfare; their psychological pressure, emotional response and progress requirement need to be paid attention to.
