HOSPITAL INFORMATION SYSTEM

Abstract

Abstract:- hospital information system (his) has evolved as an integration system of order entry systems, an administrative system, and departmental subsystems within a hospital. It has become more and more necessary for every health care staff in a hospital to use a computer terminal at almost everyday’s works. Under this circumstances, his is expected to provide the staffs with various, world-wide information for decision making and better communication environment which can be used just on the terminals for everyday’s works. The implementation of the hospital information system contributes to the hospital informationization construction and is an important part of China’s medical system reform. Informatization construction has been carried out in hospitals across the country, but high investment does not necessarily lead to outstanding performance results, and there is a paradox of IT productivity. This paper analyzes the influence mechanism of the hospital information system on doctors’ work performance from two aspects: personal perception of system and individual self-efficacy. Empirical studies have found that doctors’ perception of usefulness, perception system customization and self-efficacy have a significant positive impact on doctors’ job performance during the use of information systems. This article will deepen and enrich the understanding of hospital information system performance theory, which will help further research on information system performance in the future.
