Abstract: Objective: To design and develop an early activity information management system based on multidisciplinary team collaboration for critically ill patients, and evaluate the application effects. Methods: The early activity information management system was designed to realize the early activities risk assessment, the early warning and reminder function, monitor the whole process, and closed-loop management. The application effects before and after the use of the system were assessed. Results: After the application of the information system, the average time point performing first activity risk assessments for critically ill patients was advanced from 18.27±4.00 hours to 7.72±3.42 hours after their admissions to ICU; the average time point implementing first activity was advanced from 29.35±3.92 hours to 19.34±3.87 hours after their admissions to ICU; the incidence of sports-related adverse events was reduced from 1.491‰ to 0.185‰; and the rate of unplanned interruption of activity was reduced from 8.930‰ to 2.215‰. All these differences were statistically significant (P<0.05). Multidisciplinary team members were highly satisfied with the system. Conclusion: The application of early activity information management system has achieved precise, timely and complete early risk warning control and closed-loop management of early activities, which can improve the work efficiency of multidisciplinary team members and effectively ensure the patients' safety.
