如何有效降低影像废片率

摘要

Objectire:To explore the effective method to improve the quality of imaging,reduce waste film,radiation dose and medical cost.Method:According to image quality control protocol,the quality of images in our department was as-sessed every day from 2007 to 2013.The causes for waste films were analyzed and then improvement was carried out.Waste rate was calculated.Results:The rate of waste film in 2007,2009,2010 and 2013 was 0.29%,0.12%,0.14% and 0.06%, respectively.Compared with that of 2007,the waste rate of 2009 was reduced 17%,and when compared wtih 2012,the waste rate of 2013 was reduced 8%.The mean waste rate in the 7 years was 0.12%.Conclusion:Strict quality control,anal-ysis of the causes of waste films and improvement in daily work can be effective methods to reduce the rate of waste film.%目的：探讨如何提高成像质量，减少废片率，降低病人辐射剂量，从而减低医疗运行成本。方法：2007年－2013年，根据质控要求对每天的图片质量进行评估，结合用片量，算出废片率。定期对废片产生的原因进行分析，提出改进措施并在临床工作中执行。结果：2007年废片率为评定0．29％，2009年为0．12％，2009年比2007年降低17％；2010年为0．14％，2013年为0．06％，2013年比2010年降低8％；2007－2013年这7年的平均废片率为0．12％。结论：对技术工作严格管理，按质控标准操作，对废片产生的原因进行认真分析并进行改进，能有效降低废片率。
