Abstract: 【Abstract】Objective The continuous renal replacement therapy (CRRT) nursing information system is designed to solve the problems of clinical nursing record preservation, resource sharing and human cost, and to provide safe and high quality care for patients. Methods The information items required in the CRRT nursing information system were selected by questionnaire survey, literature retrieval and conference discussion. These items were automatically obtained from the hospital information system, analyzed, classified and visualization. The application effect of this system was evaluated by questionnaire survey and quality management. Results The CRRT nursing information system contained 128 items organized into 9 categories, including 16 items of patients' basic information, 20 items of nursing evaluation before CRRT, 6 items of adjustment of medical orders, 17 items of medication orders, 23 items of nursing monitoring during CRRT, 3 items of nursing measures, 20 items of bedside blood gas analyses, 6 items of summary of intake and output volume, 17 items of nursing evaluation after CRRT. Compared with the manual record, the time spent on the CRRT nursing information system shortened significantly (t=29.305, P＜0.001). Conclusion CRRT nursing information system can optimize the CRRT nursing processes, ensure the quality of nursing records, improve work efficiency, and promote scientific research output.
