Exposure to ionizing radiation, such as that used in fluoroscopy, can lead to cataracts. This is relevant in orthopedic surgery as fluoroscopic procedures are commonly performed. In this study, we determined perceived level of: (1) personal risk, (2) awareness of risk for cataract formation due to ionizing radiation exposure, (3) awareness of occupational dose limits for ophthalmologic radiation exposure, (4) current radioprotective practices amongst orthopedic surgeons. Canadian Orthopaedic Association members were asked to participate and 264 responses (23%) were received. Many respondents believed that they were at least at moderate risk for cataract formation due to occupational radiation exposure (n = 107; 41%). Fifty-nine respondents (22%) indicated that they lacked sufficient knowledge to estimate risk and almost half (n = 120; 45%) reported having minimal awareness that ionizing radiation may contribute to cataractogenesis; almost 75% (n = 197) reported having minimal awareness that dose limits exist. The association between perceived risk and awareness was significant (P<.001). There is an information deficit among orthopedic surgeons regarding awareness of either the potential cataractogenesis risk due to radiation exposure or the dose limits.
暴露于电离辐射,如荧光透视中所使用的辐射,可能会导致白内障。这在骨科手术中具有相关性,因为荧光透视程序经常被执行。在本研究中,我们确定了以下方面的认知水平:(1)个人风险,(2)对因电离辐射暴露而形成白内障风险的认知,(3)对眼科辐射暴露职业剂量限值的认知,(4)骨科外科医生当前的辐射防护措施。我们邀请了加拿大骨科协会成员参与,共收到264份回复(23%)。许多受访者认为,由于职业辐射暴露,他们至少有中度患白内障的风险(n = 107;41%)。59名受访者(22%)表示他们缺乏足够的知识来估计风险,近一半(n = 120;45%)报告称对电离辐射可能导致白内障发生的认知极少;近75%(n = 197)报告称对存在剂量限值的认知极少。感知风险与认知之间的关联具有显著性(P <.001)。骨科外科医生在对辐射暴露导致白内障发生的潜在风险或剂量限值的认知方面存在信息不足。
