| Abstract:: |
| Objective To provide guidance on the rational applications of the clinical X-ray examination through analyzing the positive rates of X-ray diagnostic examination of Shandong province. Methods Through questionnaires,the annual number of X-ray diagnostic examination of the whole province was investigated,according to it,hospitals were arranged decreasingly into four levels,and proceeded the stratified random sampling on the rations of 9%,6%,3.5%,1.5%.In this survey,the distribution and positive rates of all kinds of X-ray examinations in the light of the four levels were studied. Results In all kinds of X-ray examinations,the positive rates of mammography,dental panoramic radiography,body CT,cerebral angiography,urography,cardiac angiography are higher.In four levels of hospitals,the positive rate of the second level is 63%,the highest;those of the first and third levels are 58%,the same;and that of the forth level is 40% the lowest.In this study,we preliminarily provided the reference value of the positive rates of all kinds of X-ray examinations.If the positive rates increase to it,the annual costs of public medical service can decrease by about $65 millionm,and annual public collective doses by 3,900 man5Sv. Conclusion Increasing the positive rates of all kinds of X-ray examinations can promote the rational applications of X-ray examination,decrease the medical service costs,and deduce the public collective doses. |
