In the first quarter of 2014, a proposal to write an NCRP report on Evaluating and Communicating Radiation Risks for Studies Involving Human Subjects: Guidance for Researchers and Reviewing Bodies was approved by the BOD, and SC 4-7 was formed.
Tens of thousands of individuals participate annually in clinical trials and research studies involving human subjects. Many of these studies expose the subjects to ionizing radiation, often through imaging examinations. Currently, there is limited and varied guidance available to assist researchers and institutional review boards in preparing protocols that involve radiation exposure to humans. Further, institutional review board members may have only limited knowledge of which imaging studies utilize ionizing radiation [e.g., computed tomography (ionizing) versus magnetic resonance imaging (nonionizing)]. For those imaging procedures that do utilize ionizing radiation, researchers may not have determined absorbed doses, nor have the educational background to properly communicate to subjects the risk of potential health effects from radiation exposure. Consequently, researchers and institutional review board members would greatly benefit from clear guidance on assessing proper utilization of radiation, estimating radiation risks and benefits, and ensuring that informed consent statements have consistent, comprehensible and accurate language.
Topics to be included in this report are:
- identification of experimental studies utilizing ionizing radiation;
- assessment of proper utilization of radiation in a research protocol;
- estimation of radiation absorbed dose;
- estimation of radiation risks including adjustments for specific populations (e.g., young children versus terminally ill adults);
- distinguishing between radiation required for standard patient care and that incurred specifically by research study design;
- optimization of radiation dose;
- important elements of informed consent statements for protocols involving ionizing radiation, including communication with appropriate risk language; and
- templates for informed consent documents.
The first teleconference of the Committee (April 7, 2014) involved discussion of membership and the path forward for a report outline. At the second teleconference (May 8, 2014) there was additional discussion on Committee composition, as well as approval of the first teleconference minutes, receipt of comments towards finalizing the draft outline, and initial timeline planning. At the third meeting (webinar/teleconference, June 19, 2014) new Committee members were introduced, minutes of the second meeting were approved, a formatted draft report table of contents was reviewed, and comments towards finalizing the draft outline and writing assignments took place. Committee membership was again discussed with a decision to add a medical ethicist as a consultant and to table addition of patient/consumer advocate and other disciplines for the time being.
At the fourth meeting (webinar/teleconference, August 14, 2014) minutes of the third meeting were approved, submitted text was reviewed, the Committee writing assignments were updated, and the draft report was subsequently revised through revision 1g (August 24, 2014). Additional meetings were held during the fourth quarter: a fifth meeting on October 8, 2014; and, a sixth meeting on November 20, 2014. At both meetings, additional discussion took place on finalizing the approach to be taken with the draft report and changes were made in the planned organization. By the end of the quarter, the draft report had been revised through revision 2a (November 20, 2014) and all members had received writing assignments. A subject matter expert in radiation oncology physics was invited and agreed to join the Committee.
The Committee held meetings via webinar/teleconference on January 12, 2015 (seventh Meeting) and March 25, 2015 (ninth Meeting). The Committee had its first face-to-face meeting (eighth Meeting) at the University of California-Davis Medical Center campus in Sacramento, California February 9–10, 2015. At and following these meetings substantial progress was made on a draft report (revision 4L by the end of the quarter) and Committee membership was completed by adding Patricia Fleming (previously a consultant) and Steven Sutlief (Radiation Oncology Medical Physicist) as full members. By the end of the quarter, all sections of the draft report had text in place save the Executive Summary, Conclusions and Recommendations, and Appendices.
Committee meetings via webinar/teleconference were held on May 4, 2015 (10th meeting) and June 11, 2015 (11th meeting). Additional progress was made on the draft report which was in revision 4V by the end of the quarter. Additional work during the next quarter will focus on completing the Executive Summary, Conclusions and Recommendations, and Appendices.
A Committee meeting via webinar/teleconference was held on September 11, 2015 (12th meeting). Substantial progress was made on the draft report which was in revision 5c by the end of the third quarter.
The 13th Committee meeting via webinar/teleconference took place on November 3, 2015. An Appendix A Working Group meeting via webinar/teleconference took place on December 9, 2015. Additional progress was made on all sections of the draft report by the end of the fourth quarter of 2015.
The 14th, 15th and 16th meetings via teleconference/webinar of the were held on January 12, 2016; February 19, 2016; and March 22, 2016. A second and final meeting of the Appendix A Working Group meeting via webinar/teleconference was held on February 9, 2016. Substantial progress was made on developing a final consolidated draft report by the end of the first quarter of 2016.
The 17th meeting of the Committee is scheduled to be held at NCRP on April 9, 2016.
NCRP is grateful to the Centers for Disease Control and Prevention for financial support of this work.
