Are We Adequately Communicating the Potential Radiation Risks to Patients Undergoing Nuclear Medicine Examinations? A Clinical Audit

Introduction: We assessed whether the communication of potential radiation risks from nuclear medicine examinations to patients, which is required by law, is adequate. Methods: We performed an audit to assess the adequacy of communication to patients, with two targets: (1) they received sufficient information about the potential radiation risks; and (2) they understood the information before they consented to the examination. We aimed at 100% of patients achieving both targets. If they did not, we planned to implement changes to bring our practice in line with these standards. A total of 53 patients undergoing examinations during a randomly selected week were recruited to fill out a questionnaire. Results: The audit showed that the targets were not achieved, with only 45% of the participants (95% confidence interval = 33-59%) reporting that they both received sufficient information and understood the potential risks. A series of changes were implemented, including distribution of a newly designed one-page information pamphlet to all participants, provision of a newly designed one-page reference sheet to the clinical team, and design of a new workflow for radiographers. Another 53 patients were recruited for re-audit, and the effect of the changes was assessed by comparing the results between the audit and re-audit, using the Chi squared test. These changes were associated with statistically significant improvements in both targets from 45% to 100% (p < 0.0001). Conclusion: When patients are provided with an easy-to-understand information pamphlet and the clinical team are instructed to assist patients in understanding the information, the communication targets are achievable.
