Patients' knowledge of and Perspectives Regarding the Risks and Dosage of Diagnostic Radiation

Abstract

Background: Medical imaging is an increasingly important source of radiation exposure for the general population, and there are risks associated with such exposure; however, recent studies have demonstrated poor understanding of medical radiation among various groups of health care providers. Ionizing radiation is a helpful diagnostic tool in a wide range of medical specialties. However, it imposes a risk of radiation exposure to both patients and healthcare professionals. The study aims: Evaluate the level of knowledge of patients toward radiation exposure hazards and radiation dose. Methods: The study was a qualitative cross-sectional study in Jeddah, KSA from January to July. Data were collected through a self-administered online questionnaire that was distributed electronically to the patients who underwent the diagnostic radiological procedure. Data were represented in terms of frequencies and valid percentages for categorical variables. A one-way analysis of variance test was used to compare numerical variables between subgroups. Results: The mean knowledge score was below average (5.08 ± 2.952). Patients aged between 18 and 25 years, and single patients had significantly higher mean scores. Patients who were advised about the hazards of radiation showed a significantly higher mean score. These informed patients had the highest mean score in the entire sample population. Conclusion: The level of knowledge of patients toward risks of radiation exposure is inadequate. Further research is required for investigate patients' awareness regarding the risks and dosage of diagnostic radiation on a national level. Awareness promotions are highly recommended to improve the level of knowledge.
