Abstract

Introduction: In order to minimise adverse effects or patient injuries related to the effect of iodinated contrast media (ICM) on the thyroid, international guidelines and research recommend developing routines for identification and management of patients at risk of developing a thyroid dysfunction. This study aimed to investigate thyroid-related ICM administration practices among diagnostic imaging departments in Norway.

Methods: The cross-sectional survey included 24 hospitals and 75 respondents with a 69% response rate. The survey covered practices for assessment and management of at-risk patients and the participants' perceived rationale for the routines.

Results: The use of written checklists as recommended by international guidelines was quite modest (15%) and the respondents preferred various methods to identify risk and contraindications. Only 20% reported checking for any scheduled thyroid-scintigraphy and/or radioactive-iodine therapy. 42% indicated that they did not have thyroid-related ICM routines, and the main perceived reason was lack of knowledge on the topic. Radiographers and radiologists expressed uncertainty about each other's roles and routines.

Conclusion: This study revealed the need of optimisation of routines regarding ICM administration to patients at risk for thyroid dysfunction.

Keywords: Computerised tomography; contraindications; contrast media; quality assurance.
