Though the attending system was first implemented in 2003 to facilitate the efficient utilization of medical resources and specialties, only a few hospitals and physicians are participated in that system. The purpose of this study was to investigate the actual facts which related to operation of attending system and propose a basic information to revitalized of the attending system in Korea. The data were collected between August 1 and October 30, 2005 from 25 hospitals and 42 attending physicians who were in part of the attending system. Medical institutions were unwilling to participate despite the advantages of the attending system with respect to the utilization of medical resources and improvement in the quality of medical services. The primary reason for this was the lack of understanding among physicians about the attending system and the difficulty(lack of time) encountered by the attending physicians in administering care to patients hospitalized in the attending hospitals. Moreover insufficient reimbursement for rendered medical services constituted another important reason. In conclusion, we can state that the establishment of a committee is required to discuss the issues surrounding the attending system and to control the growing disparity between the viewpoints of hospitals and physicians. Regardless, there is a need to develop economical incentives for medical institutes. The attending system served as a useful policy in promoting the medical service system and bringing about an improvement in the management of medical institutes.
