Medical quality control is at the core of the various managerial tasks of the hospital and the managerial ideas involved determine the quality of the control. The authors analyze in depth the structural features of fundamental, link and terminal medical quality, and in light of their experience in hospital management, put forward a principle of and a framework of ideas for medical quality control. The principle is as follows: focusing on the patients, putting quality at the core, laying equal stress on fundamental, link and terminal quality, and promoting simultaneously self-control and supervision in an all-round way. The framework of ideas is as follows: focusing on the patients should be based on putting quality at the core; fundamental medical quality should be based on basic rules and regulations; link medical quality should be based on the "three basics and three aspects of strictness" ; and terminal medical quality should be based on the education and involvement of the entire staff.
