Brief Summary

Surgical procedures involving X-rays in the operating room have increased in recent years, thereby increasing the exposure of operating room staff to ionizing radiation. An individual dosimeter makes it possible to record the radiation exposure to which these personnel are exposed. However, it has been noticed that these dosimeters are not thoroughly worn, consequently the radiation doses recorded are not reliable. In order to increase the proportion of dosimeters systematically worn in the operating room, we study the impact of the association of the passive dosimeter with the hospital access badge (forming the Badge-Dosi). A first pilot study was carried out at Tours University Hospital showing the effectiveness of this concept. With the present study, we carry out a multicenter study. Our hypothesis is that the Badge-Dosi allows a significant increase of dosimeter use in the operating room, which improves the reliability of the monitoring of personnel.

Outcome Measures

Primary Outcomes (1)

  • Improve the wearing of dosimeters by staff exposed to X-rays and working in the operating room thanks to the BadgeDosi solution in order to make the exposure measurements taken more reliable and interpretable compared to the passive dosimeter alone. (TES

    Passive dosimeter wearing status (alone versus BadgeDosi) assessed once by an independent observer over the M6 period (during the sixth month of the study, TEST group).

    6 months

Secondary Outcomes (6)

  • Evaluate the wearing rate the passive dosimeter assessed by questionnaire at M0, M3 and M6 (TEST group)

    Month 0, month 3 and month 6

  • Study the evolution of radiation read on the BadgeDosi versus passive dosimeter alone among agents working in the operating room (TEST group).

    Month 3 and month 6

  • Study the variations of doses of a control group wearing the BadgeDosi but not exposed to ionizing radiation as part of their activity in the hospital (VIE group).

    Month 3 and month 6

  • Collect user feedback on the ergonomics the BadgeDosi (TEST and VIE groups).

    Month 3 and month 6

  • Monitor natural radioactivity between the healthcare center and the staff's homes. Special care is taken so the distribution of the places of residence of the staff around the hospital is represented (HOME group).

    Month 3 and month 6

  • +1 more secondary outcomes

Study Arms (2)

Dosimeter alone

NO INTERVENTION

Dosimeter alone as usually used in hospital unit exposed to radiation

Dosimeter combined with access badge

EXPERIMENTAL

Dosimeter will be combined with the badge that providing access to hospital unit

Device: Badge-dosi

Interventions

The intervention assessed consists in linking the radiation dosimeter to the access badge (which practitioners wear at all times) in order to improve compliance with radiation dosimeter wear among practitioners exposed to X-rays.
