This paper explores the application of distance education technology in standardized training of resident physicians in primary orientation training. With the rapid development and popularization of distance education technology, the special needs faced by primary medical institutions in resident physician training are becoming increasingly prominent. By analyzing the current application state, it is found that distance education technology can effectively promote the sharing of high-quality educational resources, improve the flexibility and coverage of training, moreover, it also faces challenges such as technological equipment limitations and insufficient teacher-student interaction. To optimize the application effect, this paper proposes strategies such as strengthening technical support, optimizing teaching content and form, and establishing a sound training effect evaluation system. This study not only helps to improve the training quality of primary resident physicians, but also has important significance for improving the level of primary medical services. Looking to the future, distance education technology will play a greater role in the training of primary resident physicians, which is of great significance for improving the level of primary medical services.
