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。
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 man · Sv. 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.
