Gonad contact shielding in digital radiography: A questionnaire survey

Abstract

Purpose: The use of gonad contact shielding (GCS) in radiology departments has varied across countries, possibly because, until recently, there was no agreed consensus with mixed evidence supporting its use. This study aims to explore radiographers' use and opinion on GCS in digital radiography (DR) and to evaluate whether radiographers' use of GCS is associated with their gender, highest educational qualification, and/or years of experience.

Method: An online survey was sent via email to potential participants through the Society of Medical Radiographers Malta (SRM) as well as social media posts on local radiography pages. Descriptive and inferential statistics were used to analyse the collected data.

Results: Almost half of the registered radiographers working in radiology departments in Malta (n = 101/203) completed the survey (49.7 % response rate). 61.4 % of participating radiographers indicated they 'often' use GCS in some patients, with 56.4 % stating they perceive GCS as an effective tool to protect the gonads from radiation exposure in DR. Equally, 56.4 % claimed that GCS use is guided by local rules and/or departmental protocols. While 58.4 % indicated that patients' gender does not impact their use of GCS, patients' age does influence their use. No statistically significant association was noted between radiographers' likeliness of using GCS and their gender, highest educational qualification, and/or years of experience.

Conclusions: Some misconceptions and uncertainties among radiographers concerning the benefits and risks of using GCS were noted. Local radiology departments should look into their protocols and assess the need for an update aligned with the latest recommendations.
