Abstract
BACKGROUND
Intravenous contrast media (IVCM) are routinely used in different imaging techniques, such as computed tomography (CT) and magnetic resonance imaging (MRI), but can cause adverse effects on renal function. This study aims to evaluate the level of awareness of IVCM and their effects on renal function among members of the general public visiting King Abdulaziz University Hospital (KAUH) in Jeddah, Saudi Arabia.
METHODS
An observational cross-sectional study design was used. It was conducted in September 2018 on participants aged >= 18 years who completed an electronic selfadministered questionnaire to assess their knowledge of the adverse renal effects of IVCM. Data was analyzed using descriptive and inferential statistics. Chi-squared test was used to evaluate the level of knowledge among residents regarding the possible adverse renal events that can be caused by IVCM.
RESULTS
Most participants (56.8%) had no knowledge of IVCM and were unable to recognize the risk factors associated with IVCM and their potential impact on the kidneys. Social media was the most chosen source of information among those who had variable degrees of awareness. A statistically significant association was found between the educational level and degree of knowledge about the importance, application, and adverse events of IVCM. Most of the respondents lacked knowledge of the risk factors associated with contrast-induced nephropathy.
CONCLUSIONS
Participants generally had limited knowledge about IVCM and the associated risk factors. Educational programs could be utilized to improve awareness and understanding.
