[Staff knowledge of radiation protection in endovascular surgery]

Image intensification exposes the endovascular surgery staff to ionizing radiation. The aim of this study was to determine awareness of ionizing radiation risks among personnel working in the endovascular surgery environment and the availability of radiation protection clothes and to propose appropriate corrective measures.

This descriptive study was performed in the endovascular operating theatre equipped with a mobile image intensifier unit in La Rabta vascular department in September 2017. We visited the endovascular theatre to identify the availability of radiation protection clothes. We used a questionnaire to identify personnel knowledge about ionizing radiation. We established a global score of knowledge to classify our population.

We identified 85 professionals exposed to ionizing radiation. Sixty-four of them (75%) responded to our questionnaire; 65% were male; median age was 34 years (range: 25-61). Endovascular theatre personnel were surgeons (35%), nurses (34%), qualified technicians (18%) and other department employees (13%). The mean global score of knowledge was 8.15/20 (2-18). This score increased significantly with grade and seniority (Kruskal-Wallis test).

In the present study, the results indicate insufficiency knowledge about radiation exposure among the endovascular staff and in radioprotection tools availability. In order to minimize all unnecessary radiation, attempts should be made to increase vascular theatre staff knowledge about radiation protection. Safety culture is a referral method to reduce radiation exposure as low as possible.
