目的:对废片的现状进行调查,找出产生废片的主要原因,提出减少废片的管理措施,以指导今后的技术工作。材料与方法:材料是1998年10月至2000年3月由专人收集的全部906张废片。将906张废片按责任性废片(白板、制动、暗室因素、标记不当、错照、照重及异物干扰所致废片)、技术性废片(投照条件选择不当和投照方法不规范所致废片)、设备及材料性废料和其它类废片进行分类统计。结果:906 张废片原因归类分析中,技术性废片占 56.84％、责任性废片占34.77％、设备及材料性废片占6.84％、其它类废片占 1.55％。其中,技术性废片中,投照条件选择不当所致废片占 66.99％、投照方法不规范所致废片占 33.01％;在责任性废片中,白板性废片占37.46％、制动性废片占 24.76％、暗室因素性废片占 14.29％;在设备及材料性废片中,设备性废片占 93.55％。在 906张废片技术性原因和责任性原因发生率的比较中,技术性原因是造成废片的主要原因(P<0.05)。结论:健全组织机构,实行科主任挂帅,主管技师对技师长负责,加强多种形式的业务学习,严格技术操作规程和岗位职责,加大医德医风教育和法制教育的力度,增强责任心、建立良好的意见沟通体制,强化激励监督机制是减少废片的主要措施。
OBJECTIVE: To investigate the status quo of wastes and find out the main causes of the wastes, and put forward the management measures to reduce waste so as to guide the future technical work. Materials and Methods: The material was all 906 wastes collected by hand from October 1998 to March 2000. 906 wastes were scrapped according to the responsible waste films (white board, brake, dark room factors, improper labeling, wrong photos, heavy and foreign material interference), technical waste films Caused by scrap pieces), equipment and material waste and other waste pieces classified statistics. Results: Among the 906 pieces of waste, the percentage of technical scrap was 56.84%, that of responsible scrap was 34.77%, that of equipment and material was 6.84%, and that of other wastes was 1.55%. Among them, among the technical waste films, waste films accounted for 66.99% due to improper projection conditions and 33.01% waste films due to non-standard projection methods. In the responsible waste films, white waste films accounted for 37.46%, braking 24.76% of wastes were scrapped, and 14.29% of wastes were scrapings of dark room. In the wastes of equipment and materials, 93.55% of scrap was wasted by equipment. Of the 906 scrap pieces of technical and responsible causes of the incidence of the comparison, the technical reason is the main cause of scrap pieces (P <0.05). Conclusion: The organization and implementation department should be well-established. The chief technician should be responsible for the technician. Various types of business learning should be strengthened. The technical operation procedures and job responsibilities should be strengthened. Medical ethics and legal education should be intensified. Establishing a good opinion communication system and strengthening the incentive supervision mechanism are the major measures to reduce waste films.
