Patients knowledge about radiation exposure from different imaging modalities

Purpose Medical imaging exams are regular and unavoidable parts of diagnostic algorithms in a variety of different diseases. Some of those utilize different kinds of ionizing radiation and expose patients to it. Just the same, despite the potential harm that ionizing radiation carries to their health, patients are referred to various procedures in everyday practice. It is suspected that patients are not adequately informed about the benefits and risks of different procedures or their alternatives, as well as the risk of not undergoing an examination. The aim of this study was to identify patients knowledge about ionizing radiation used in diagnostic imaging and whether they were adequately informed by their supervising physicians about the diagnostic procedure they were referred to. Methods We did a descriptive study using an anonymous one- time survey. The study was approved by the Ethical Committee of University hospital Merkur, Zagreb. A convenient sample consisting of 416 patients, of which 201 male and 215 female, was collected. The patients in the sample which were referred to our radiology department for diagnostic imaging (X-ray, ultrasound, MRI or CT), voluntarily participated in an anonymous short survey questionnaire. For all questions frequency analyses were performed in software package STATISTICA ver.13.3. Chi-square with Yates correction was used to determine differences in patients' answers for those who got the explanation about the procedure that was administrated to them by their supervising physician and those who didn't. We also tested the differences in answers depending on the level of patients' education. Results Mean patients' age was 55.2 ± 15.6 years. Of all the patients 7.9% were without any formal education or only with finished elementary school, 53.7% had finished high school and 38.4% had a college or a higher degree. According to the obtained data 62.5% of patients got the explanation from their supervising physician about the radiological exam they were referred to. 240 patients think that the given explanation was sufficient. 93.8% of patients knew that some radiological procedures use ionizing radiation but when asked which procedure does not use ionizing radiation, only 34.4% identified the correct procedure among offered X-ray, CT, angiography, and MRI. In comparison with chest X- ray, chest CT, chest angiography and both side mammography, 25.7% chose chest X-ray as the one with the lowest radiation dose. Our results are similar to some previously published investigations in Europe or America. (1-5) When we compared the answers from patients who got the information and explanation from their physicians and those who did not, there were no significant differences. The only significant difference was noticed when patients with the lowest educational level were compared to those with the highest level. Better educated patients have better knowledge of radiological procedures and the potential risks. Conclusion The patients' knowledge about ionizing radiation used in medical imaging and associated health risks is poor. Even though 58% of patients were satisfied with the explanations received from their supervising physicians, it is obvious that the information given was not sufficient. It also brings in question the necessary knowledge of supervising physicians who are increasingly referring the patients to diagnostic imaging.
