中文摘要:

目的了解山东省X射线诊断检查的阳性率,指导临床X线检查的合理应用。方法通过回顾性调查方式普查全省范围内各医院的年放射门诊量,将年放射门诊量从大到小分为4层,并按9%、6%、3.5%、1.5%比例进行随机抽样。调查各层医院X射线诊断受检者按26种检查类别的分布及各种检查类别的阳性率。结果各类X射线检查中,乳腺摄影、口内片、牙科全景摄影、躯干CT、脑血管造影、尿路造影、心血管造影等阳性率较高。各级医疗单位X射线诊断检查阳性率以市级为最高,为63%,省级和县级相同,为58%,乡镇级医疗单位最低,为40%。初步提出了本省各类X射线诊断检查阳性率参考值,按此参考值,每年可减少公众医疗费用约6500余万元;并可降低公众接受的集体剂量3900人·Sv/年。结论提高X射线检查阳性率可促进X射线检查的合理应用,减少医疗费用,降低公众集体剂量。

英文摘要:

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.
