Abstract: Objective To design and apply the admission process based on "Internet Plus" in emergency and critical patients. Methods The hospital admission process of emergency critically ill patients was optimized through literature review and group discussion methods,and patients' family members paid online by mobile application and Wechat public account,nurses in emergency department handled admission procedures online,and the "Internet Plus" hospital admission process was developed. 124 critically ill patients who were admitted to the emergency department and hospitalized from January 2021 to March 2021 were selected as the experimental group. The experimental group used the “Internet Plus” hospital admission process. A total of 94 critically ill emergency patients who were admitted and hospitalized from October 2020 to December 2020 were selected as the control group and used the traditional admission procedures. The completion time and satisfaction of admission procedures between the two groups were compared. Semi-structured interviews were conducted to understand the medical staff's opinions on the “Internet Plus” admission process. Results The completion time of admission procedures in experimental group was 20.84 min shorter than that in control group（P< 0.05）. Nursing satisfaction of experimental group was 96.8%,and that of control group was 25.5%,and the difference between the two groups was statistically significant（P< 0.05）. Ten interviewed medical staff recognized the effects of the “Internet Plus” admission process and put forward effective suggestions. Conclusion The “Internet plus” emergency hospital admission process for emergency and critically ill patients can shorten hospital waiting time and improve patient satisfaction.
