Considering the problems of teaching consciousness, school running form and teachers construction in non-directly affiliated hospitals, this paper takes the medical personnel training of a non-directly affiliated hospital which is subordinate to Shenzhen Luohu Hospital Group as an example, in order to analyze the related exploration methods of non-directly affiliated hospitals under the development of hospital collectivization, and put forward a trinity training mode of general practitioners, which is “medical college-non-directly affiliated hospital-community health center”. This paper further discusses the challenges and possible solutions faced by non-directly affiliated hospitals in the new era.
