The Distribution And Utilization Of CT In Chengdu

Objectives: To acknowledge the distribution, utilization, management and efficiency of CT in Chengdu, and to analyze the cost, benefit and results of CT for the influential factors of efficiency and positive ratio, and to improve the effective utilization of CT in Chengdu, and to supply reference for the resource distribution more effectively.Methods: To investigate the situation of distribution, utilization, maintenance and management of CT in Chengdu, and to sample 80 cases in 1997, 2000 and 2002 respectively in every hospital to acknowledge the distribution, working, maintenance, cost, benefit, positive ratio, the existence of inducement of utilization, the effect of CT in clinical diagnosis and treatment to quest the influential factors of the results of CT for enhancing the effective utilization and optimizing the resource distribution.Results: (1)Every million people have 3.5 CT in Chengdu averagely. And the service area is 341.4 km~2 averagely. (2)77.4 percent CT are working. 61.3 percent CT are used overtime. 47.4 percent CT are second-handed. The capability of the second-handed is less than half of that of the new. AH the second-handed are used overtime. (3)There are 5.76 workers of each CT averagely. There are 10.3 percent CT who have a technological expert. (4)The mean price of CT is 255.8 yuan. 62.8 percent money purchasing CT are collected from the hospitals or the crew. The mean maintenance of CT is 170, 000 yuan annually. (5)The mean cost of working CT is 710,500 yuan annually. (6)The main place checked is head, which is 69.12 percent. The main kind of disease is traumatism, which is 28.2 percent. The main system of disease is centrum, which is 37.3 percent. (7)The positive ratio of results is 57.4%. 47.0% cases can confirmate the primary diagnosis. 56.7% cases can help to make the final diagnosis. (8)The ratio of nonrelation between the result of CTand the final diagnosis of the cases of acanthi, the cases of the skeleton and the cases of shrinkage are 28.0%, 20.9%,29.7% respectively. Conclusions: (DCT in Chengdu are more than the standard and are distributed unevenly. The mean possession of Jinjiang district is more than 10 times of that of Penzhou district. (2)Second-handed CT are worse than the new in effect and capability and should be disposed. (3)The leaders of hospitals do not emphasize the technological experts of CT, and CT are lack of qualitive workmen, which leads the high ratio of repair and the expensive maintenance. (4)The ratio of profit is 107.1%. Hospital leaders should take care of the cost-benefit analysis of each CT specially. (5)The effect of CT becomes more and more obvious as time goes and the levels of hospitals rise. (6)The ratio of inducement of utilization is 34.0%, especially in the old patients of shrinkage in skeleton.
