A national programme on patient and staff dose evaluation in interventional cardiology made in cooperation with the haemodynamic section of the Spanish Society of Cardiology has recently been launched. Its aim is to propose a set of national diagnostic reference levels (DRLs) for patients as recommended by the International Commission on Radiological Protection and to initiate several optimisation actions to improve radiological protection of both patients and staff. Six hospitals have joined the programme and accepted to submit their data to a central database. First to be acquired were the quality control data of the X-ray systems and radiation doses of patients and professionals. The results from 9 X-ray systems, 1467 procedures and staff doses from 43 professionals were gathered. Provisional DRLs resulted in 44 Gy cm(2) for coronary angiography and 78 Gy cm(2) for interventions. The X-ray systems varied up to a factor of 5 for dose rates in reference conditions. Staff doses showed that 50 % of interventional cardiologists do not use their personal dosemeters correctly.
最近启动了一项与西班牙心脏病学会血液动力学部门合作开展的关于介入心脏病学患者和工作人员剂量评估的国家计划。其目的是按照国际放射防护委员会的建议，提出一套针对患者的国家诊断参考水平（DRL），并启动若干优化行动，以改善对患者和工作人员的放射防护。六家医院已加入该计划，并同意将其数据提交至中央数据库。首先获取的是X射线系统的质量控制数据以及患者和专业人员的辐射剂量。收集了9个X射线系统、1467例手术的数据以及43名专业人员的工作人员剂量数据。冠状动脉造影的临时DRL为44 Gy cm²，介入手术为78 Gy cm²。在参考条件下，X射线系统的剂量率差异高达5倍。工作人员剂量数据显示，50%的介入心脏病专家未正确使用个人剂量计。
