Abstract

Objectives: We studied the willingness of outpatients to reduce the environmental impact of contrast media by using urine bags to collect excreted contrast material after contrast-enhanced computed tomography (ceCT).

Materials and methods: In this prospective single-center cohort study, we provided consecutive outpatients undergoing ceCT with information about contrast material excretion. We then offered urine bags to collect their urine for the first four consecutive urination sessions after the ceCT examination. An absorbent pad within these bags transforms the urine from liquid to solid so that the bags can be disposed of via the household waste system to avoid water contamination. Participants were asked to complete a questionnaire-based telephone interview after ceCT.

Results: Of the 671 consecutive outpatients undergoing ceCT, 503 patients (75%) participated in the study, of whom 476 participants (mean age, 63 years; range, 20-88 years) successfully underwent a telephone interview. 455 of 476 patients (96%) had used at least one urine bag; 84% had used 3 or 4 urine bags. Time between ceCT and use of the final urine bag averaged 9.46 h (range, 0.1-28.5 h). 434 patients (91%) were "willing to collaborate on solutions to reduce contrast agent residues in water." 380 patients (80% of participants) stated to "definitely use the urine bag again after my next ceCT scan."

Conclusion: Most outpatients were willing to use urine bags after ceCT. Urine bags were used for an average of 9 h after ceCT, ensuring that a substantial amount of the administered contrast medium does not enter the sewage system.

Key points: Question It is not known whether there is enough willingness among patients to use urine bags after contrast-enhanced CT (ceCT) to reduce contrast material in the water supply. Findings Urine bags offer a viable option to reduce the environmental impact of contrast agents and are acceptable to most outpatients. Clinical relevance The majority of outpatients were willing to help reduce the environmental impact of contrast material by using urine bags after ceCT so that excreted contrast material does not enter the water supply.

患者是否愿意帮助减少环境中的造影剂?门诊病人在计算机断层扫描后使用尿袋。
目的:研究门诊患者在ct扫描(ceCT)后使用尿袋收集排泄造影剂以减少造影剂对环境的影响。材料和方法:在这项前瞻性单中心队列研究中,我们为连续接受ceCT的门诊患者提供了造影剂排泄的信息。然后,我们提供尿袋收集他们在ceCT检查后连续四次排尿的尿液。这些袋子内的吸收垫将尿液从液体转化为固体,这样袋子就可以通过家庭废物系统处理,避免水污染。参与者被要求在ect后完成一份基于问卷的电话访谈。结果:在671例连续接受ceCT的门诊患者中,503例(75%)患者参与了研究,其中476名参与者(平均年龄63岁;范围,20-88岁)成功地接受了电话采访。476例患者中有455例(96%)至少使用过一个尿袋;84%使用过3、4个尿袋。从ceCT到使用最终尿袋的时间平均为9.46小时(范围0.1-28.5小时)。434名患者(91%)“愿意合作寻找减少水中造影剂残留的解决方案”。380名患者(80%的参与者)表示“下次ct扫描后肯定会再次使用尿袋”。结论:大多数门诊患者愿意在ceCT后使用尿袋。尿袋在ceCT后平均使用9小时,以确保大量施用的造影剂不会进入污水系统。目前尚不清楚患者是否有足够的意愿在CT (ceCT)后使用尿袋来减少供水中的造影剂。结果尿袋为减少造影剂对环境的影响提供了一种可行的选择,为大多数门诊患者所接受。大多数门诊患者愿意在ceCT后使用尿袋,以帮助减少造影剂对环境的影响,使排泄的造影剂不会进入供水系统。

期刊介绍: European Radiology (ER) continuously updates scientific knowledge in radiology by publication of strong original articles and state-of-the-art reviews written by leading radiologists. A well balanced combination of review articles, original papers, short communications from European radiological congresses and information on society matters makes ER an indispensable source for current information in this field. This is the Journal of the European Society of Radiology, and the official journal of a number of societies. From 2004-2008 supplements to European Radiology were published under its companion, European Radiology Supplements, ISSN 1613-3749.
