Assessment of Physicians’ Knowledge and Awareness About the Hazards of Radiological Examinations on the Health of Their Patients at a Tertiary Care Hospital, Riyadh, Saudi Arabia

Knowledge, Attitude, and Practices Regarding Radiation and its Hazards Among Orthopaedic Surgeons in India: A Questionnaire-Based Study

Introduction

Orthopaedic surgeons are among the most frequent users of radiation and are often exposed to X-Ray radiation regularly. There is an overall unsatisfactory level of knowledge, attitude, and practices regarding the same among surgeons. This study aimed to assess the practices among orthopaedic surgeons regarding radiation and its hazards in India.

Methodology

This questionnaire-based survey was conducted between March and September 2022. The questionnaire broadly assessed the knowledge, awareness, and practices among orthopaedic surgeons regularly exposed to X-ray radiation. The questionnaire consisted of objective and Likert scale questions which were distributed to the respondents electronically using publicly available contact information. A qualitative review of interpretations obtained from the responses and available evidence in the literature was then performed.

Results

The response rate for the survey was 36.4%. 65.9% reported using trunk protection all the time during procedures. 57.1% of respondents reported not using thyroid protection during procedures. 92.3% reported not using protective goggles and 100% did not use appropriate gloves. 76.9% were not issued dosimeters, and only 5.5% of those who had been issued one wore it during radiation procedures. 58.2% reported having a dedicated employee to operate the machine. 86.8% of respondents did not have formal training and 81.3% were not aware of institutes offering formal training.

Conclusion

There is very high compliance with the use of protection aprons among the respondents however, the use of other apparel like thyroid shields, protection goggles and gloves was poor. The awareness regarding radiation exposure was also poor as most respondents were not issued dosimeters, however, those issued with one were well aware of their exposure. It is imperative to prioritize both surgeons' and patients' safety where radiation exposure is concerned.

Assessment of radiographers' knowledge about radiation doses and DRLs in computed tomography departments in Jeddah, Saudi Arabia: A cross-sectional study

Objective

To assess radiographers' understanding of radiation safety considering the newly approved national diagnostic reference levels (DRLs) as an optimization tool for radiation dose.

Methods

A cross-sectional study was conducted in Saudi Arabia among radiographers working at local hospitals in Jeddah city from February to March 2022. The survey comprised of 22 questions involving demographic information; and general information related to radiation dose; CTDIvol and DRLs. Data were analyzed using IBM SPSS Statistics version 26. Chi-square test was used to compare demographic groups regarding their distribution of responses with 0.05 as the level of significance.

Results

A total of 169 radiographers participated in the study (39 % females, 60 % males). Most of the participants (91 %) were aware of the description of the ALARA principle. It was noted that (47 %) of the participants indicated that the routine scanning protocols are designed by the radiologists. The majority of them (78 %) were confident to manipulate the CT scanning parameters properly. In addition, half of the participants (53 %) were aware of the CTDIvol and DLP. Unexpectedly, none of the demographic variables were significantly associated with the radiographers' knowledge about radiation dose, p-values are > 0.05.

Conclusion

Although radiographers demonstrated good knowledge of radiation protection, limited awareness of DRLs was noted among radiographers and lack of implementing and optimizing the local dose of the DRLs in this study. Therefore, education and training for healthcare professionals including radiographers are necessary to enhance clinical practical performance in radiology departments.
