Understanding of Saudi Population on the Usage of Intravenous Contrast Media Injections in Radiology

Abstract

Background: Intravenous contrast media (IVCM) in radiology are extremely important for accurate diagnosis and are used daily all over the globe. These contract media are very safe if administered correctly. However, adverse events have also been reported. This study was undertaken to determine the understanding of the patients towards the usage of IVCM in radiology. Methods: This is a cross-sectional study conducted on patients recommended for IVCM-mediated radiological examinations. The data were collected by face-to-face interactions using the self-administered questionnaire before IVCM administration. The questionnaire was all about patient’s information for IVCM usage, their associated benefits and risks. Results: Out of 225 patients who participated, a majority (72%) had insufficient knowledge of IVCM-associated risks and benefits. Both male and female patients showed a similar understanding of IVCM (p>0.05). Educated patients showed better understanding than uneducated patients (p<0.001). Similarly, employed patients demonstrated a higher level of understanding of IVCMs compared to unemployed patients (p<0.05). Moreover, 63.5%, 45.3% and 62.2% of patients believed that IVCM caused cancer, cardiovascular disorders, and adverse allergic reactions, respectively. Moreover, 52.4%, 33.3% and 49.3% of patients believed that IVCM caused shortness in breath, loss of consciousness and increase of heart rate, respectively. In addition, 29.3%, 62.2% and 20.0% of patients also advised diarrhea, itching and convulsion, respectively. Conclusion: Overall, patients’ knowledge was unsatisfactory for understanding contrast media in radiology. This study recommends that the Ministry of Health, Saudi Arabia, should arrange frequent awareness programs on contrast media in Qassim.
