Abstract:
Introduction
Contrast media use is high in computed tomography (CT) and the potential for infection risk exists given a receptive environment for bacterial growth and human error. The aim of this study was to explore radiographers’ variations in practice when using contrast media injectors in the CT environment, with a focus on infection prevention and control (IPC).
Methods
A think-aloud qualitative research approach was used, novel to understanding radiographers’ decision-making process. The setting involved a simulated scenario in a CT imaging suite, integrating equipment appropriate to contrast media CT procedures. Data collection was undertaken across four continuous stages: (1) Injector set up, (2) connecting to the patient, (3) disconnecting from the patient, and (4) post-procedure cleaning. Think-aloud responses were transcribed verbatim and qualitatively analysed.
Results
A total of 20 radiographers participated in the study. Variations in overall practice, use of gloves and hand hygiene were observed across all four stages of the simulated procedure, with a strong link observed between clinical knowledge, grounded in previous experience and clinical reasoning. Radiographers considered patient comfort, safety protocols to prevent infections, and the efficient use of contrast media during shortages or in routine practice. Some actions considered to pose an infection risk to sterile equipment components were identified.
Conclusion
The decision-making process of radiographers using contrast media injectors in CT is crucial, especially in the context of IPC. With the increasing use of contrast media in CT for enhanced imaging and diagnosis, understanding the strategies for safe and effective use is vital.
