Despite the high volume of contrast-enhanced computed tomography (CECT) examinations, there is limited awareness about its risks among patients and little is known about the influence of patient information sheets.
The objective of this study was to assess patients' awareness and perception of risks related to CECT examination and how they are influenced by an information sheet.
A total of 263 adult patients scheduled for a CECT examination completed a questionnaire. The first page evaluated patients' characteristics, their fear and awareness about examination-related risks, and source of information. Page 2 contained the Zung self-rating anxiety scale. After reading the information sheet, patients completed page 3 that surveyed how their awareness and fear had changed.
Nearly half of the patients underestimated the risk of secondary malignancy (n = 121, 46%), or the risk of renal impairment (n = 110, 42%). The vast majority (n = 227, 86%) stated that they were not instructed to maintain fluid intake up to 1 h before the procedure. After reading the information sheet, patients generally corrected their knowledge, but 195 (74%) reported experiencing greater fear (p < 0.0001). Fear was more pronounced in younger female patients who had not undergone CT previously. Patients feared the result more than examination-related risks. Most patients (n = 204, 78%) would feel uncomfortable before receiving the examination result.
Most patients do not assess risks related to CECT examination correctly. Although the information sheet improves patients' understanding of CECT-related risks, it lacks empathically delivered reassurance and increases their fear. Fast communication of examination results would make patients feel more comfortable.
尽管进行了大量的对比增强计算机断层扫描（CECT）检查，但患者对其风险的认识有限，对患者信息表的影响知之甚少。
本研究旨在评估患者对 CECT 检查相关风险的认识和感知，以及信息表对其的影响。
共有 263 名计划进行 CECT 检查的成年患者完成了一份问卷。第一页评估了患者的特征、对检查相关风险的恐惧和认识，以及信息来源。第二页包含了 Zung 自评焦虑量表。阅读信息表后，患者填写了第三页，以调查他们的意识和恐惧有何变化。
近一半的患者低估了继发恶性肿瘤的风险（n = 121，46%）或肾功能损害的风险（n = 110，42%）。绝大多数患者（n = 227，86%）表示，他们没有被告知在检查前 1 小时保持液体摄入。阅读信息表后，患者通常会纠正他们的知识，但有 195 名（74%）报告说他们感到更恐惧（p < 0.0001）。恐惧在以前没有做过 CT 的年轻女性患者中更为明显。患者更担心检查结果，而不是与检查相关的风险。大多数患者（n = 204，78%）在收到检查结果之前会感到不适。
大多数患者不能正确评估与 CECT 检查相关的风险。尽管信息表提高了患者对 CECT 相关风险的理解，但它缺乏共情的安慰，并增加了他们的恐惧。快速传达检查结果会让患者感到更舒适。
