Method for bAdge-dosi Monitoring of X-ray Exposure Values in Operating Theatre Surgery
A study testing Badge-dosi in people with X-Ray, run by University Hospital, Tours at 4 sites in France.
Trial 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. Read more about this study

About this study
Official title: Method for bAdge-dosi Monitoring of X-ray Exposure Values in Operating Theatre Surgery: a Multicentre Randomised Trial
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Badge-dosiDevice
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.
| Study group | Role | What they receive |
|---|---|---|
| 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 Receives: Device: Badge-dosi |
What is being measured
The primary outcome is the main question the study is designed to answer.
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).
Measured: 6 months
Secondary outcomes (6)
Evaluate the wearing rate the passive dosimeter assessed by questionnaire at M0, M3 and M6 (TEST group)
Passive dosimeter wearing rate is assessed at M0, M3 and M6 by a declarative questionnaire (TEST group).

Measured: Month 3 and month 6

Difference in radiation measured in mSv between healthcare center and staff's homes (HOME control group, M3 and M6).
