This study focuses on the work performance of nurses in public hospitals and comprehensively reviews relevant research results. Performance management originated in the 1970s and is crucial in the development of public hospitals. Nurse performance covers multiple dimensions, including nursing quality and work efficiency, and is affected by individual, organizational and external factors. In China, performance management of public hospitals is promoted by policies, but there are problems such as concept confusion, unfair evaluation, insufficient informatization and low employee participation. Studying nurses' work performance is of great significance for improving hospital service quality and optimizing management. In particular, under the background of informatization, it explores the correlation between nurses' attitude towards HMIS and performance, filling the research gap. Therefore, the purpose of this review is to clarify the direction for subsequent research, help optimize the design and implementation of HMIS, improve nurses' job satisfaction and efficiency, improve the overall quality of medical services, and promote the development of public hospitals towards high quality.
