Slovenian patients' knowledge on radiation and radiologic imaging modalities and their expectations of informed consent discussion

Medical imaging is considered a useful technique for diagnostic purposes. However, radiologic procedures based on the use of ionizing radiation carry possible health risks. Consequently, patients' knowledge about radiation plays a key role in their treatment process, especially in terms of reducing unnecessary exposure. The aim of this study was to assess patients' level of knowledge regarding radiation and medical imaging procedures and to correlate it with the availability of such information provided upon x-ray imaging. Online questionnaires were distributed to patients after they underwent x-ray imaging to investigate the extent to which patients understood the procedure. We also examined whether patients took the initiative to learn about the procedure, how they perceived the radiographers, how they experienced the medical procedure, and how satisfied they were with the treatment. Information that the patients acquired from the medical professionals (p = 0.006) or by self-educating on the topic (p < 0.001) is associated with their understanding of radiation. In contrast to gender and age, a statistically significant association between education and patients' knowledge was revealed (p = 0.008). The results also showed an association between gender and patients' comfort during imaging, revealing that females are more likely to experience emotional distress (p < 0.001). Satisfaction is statistically significantly higher when patients tend to educate themselves on the topic (p = 0.038). Most clients were informed about why they had to undergo x-ray imaging, however, they did not receive information about radiation and its risks upon examination. This resulted in inadequate patient knowledge. In order to improve patients’ awareness, comprehensive educational programs should be implemented into the clinical practice.
