OBJECTIVES: This study aimed to estimate the proportion of patients increasing while using revolution CT and to evaluate the impact of it in diagnosis time, length of stay, rate of direct discharge and hospitalization costs, while comparing to regular CT METHODS: The data including rates, costs, time of diagnosis and length of stay, collected from literature reviewing and expert consultation, we use decision tree model to carry out a cost-effectiveness analysis by using treeage software  RESULTS: The study shows that with revolution CT, we can increase the percentage of CCTA patients by 19.1%, shorter the diagnosis time by 8.45 hours, decrease the length of stay by 0.64 days, increasing direct discharge rate by 9% and lower median cost of care per patient by 600 yuan while comparing to regular CT. CONCLUSIONS: Results of this study indicate more serviceable patient population, faster hospital discharge, shorter diagnosis time, length of stay and lower hospitalization costs with the use of revolution CT. The revolution CT is more cost effective.
