AAPM Submits Comments to the Joint Commission in response to the Proposed New National Patient Safety Goal on Pediatric Computed Tomography (CT) Imaging

The Joint Commission was seeking input on a proposed new National Patient Safety Goal (NPSG) on Pediatric Computed Tomography (CT) Imaging. Published data about the frequency of pediatric CT imaging varies. Despite evidence that use of CT may have stabilized or is declining after a period of increased use, there is an opportunity to further prevent unnecessary radiation exposure for children. An NPSG would spotlight this issue, and would motivate accredited organizations to use evidence-based practices for determining when CT examinations are necessary.

FDA Approves ACR's Digital Mammography Manual - updated March 11, 2106

This alternative standard was approved and became effective on February 17, 2016. It has no time limit. The alternative standard allows for the use by mammography facilities of the ACR Digital Mammography Quality Control Manualas an alternative to the quality assurance program recommended by the image receptor manufacturer. The FDA has determined that the ACR's quality control manual is, as required in § 900.18(a)(1): Alternative Requirements, “at least as effective in assuring quality mammography” as following the manufacturers’ QC manuals. For the most recent FDA assistance, please visit Frequently Asked Questions about DBT and MQSA Training Requirements. If there are additional questions, contact the FDA Mammography Facility Hotline at 1-800-838-7715 orMQSAhotline@hcmsllc.com.

NOTE from ACR: The ACR manual is currently undergoing preparation for publication and should be available this spring. ACR-accredited mammography facilities and those applying for accreditation will be invited to download the PDF manual at no charge; medical physicists associated with ACR-accredited facilities will also be allowed to download the manual at no charge.

NRC Issues Update to Yttrium-90 Microspheres Licensing Guidance added March 1, 2016

On February 17, 2016, the U.S. Nuclear Regulatory Commission (NRC), in conjunction with the Agreement States through a joint working group, issued revision 9 to the licensing guidance for Yttrium-90 (Y-90) Microsphere Brachytherapy Sources and Devices TheraSphere® and SIR-Spheres®.

The licensing guidance for Y-90 microsphere brachytherapy was initially published in October 2002 and subsequently revised in 2004, 2007, 2008, 2011, and 2012. Based on recommendations from the Advisory Committee on the Medical Uses of Isotopes (ACMUI) (ADAMS Accession No.ML14300A138), the joint working group revised this licensing guidance. This current licensing guidance revision has three major changes based on these ACMUI recommendations.These changes (1) remove specifications for gastrointestinal tract and lung dose/activity in the written directive and exclude reporting dose/activity to an organ or tissue other than the treatment site as a medical event when the dose/activity is caused by shunting when the shunting was evaluated prior to treatment in accordance with manufacturer’s procedures, (2) specifically exclude reporting of events due to stasis or emergent patient conditions, and (3) allow for interventional radiologists certified by the American Osteopathic Board of Radiology to become Authorized Users.The licensing guidance may also be found on the NRC Medical Uses Licensee Toolkit at www.nrc.gov/materials/miau/med-use-toolkit.html#et.

If you have questions regarding the Y-90 Licensing Guidance, please contact Katie Tapp at (301) 415-0236 or Katherine.Tapp@nrc.gov.

If you have questions about the ACMUI meeting notice, please contact Sophie Holiday at (301) 415-7865 or Sophie.Holiday@nrc.gov.

Additional presentations will be posted when available.  If you have any questions related to the “Purpose of Medical Event Reporting”, please contact Said.Daibes@nrc.gov. If you have any questions related to the “Medical Event Presentations”, please contact Sophie.Holiday@nrc.gov.

Draft ICRP report “Diagnostic Reference Levels in Medical Imaging Available for Comment - added February 2016

The International Commission on Radiological Protection (ICRP) first introduced the term ‘diagnostic reference level’ (DRL) in Publication 73 (1996). The concept was subsequently developed further, and practical guidance was provided in 2001. DRLs have been proven to be an effective tool that aids in optimization of protection in the medical exposure of patients for diagnostic and interventional procedures. However, with time it has become evident that additional advice is needed. There are issues related to definitions of the terms used in previous guidance, determination of the values for DRLs, the appropriate interval for re-evaluating and updating these values, appropriate use of DRLs in clinical practice, methods for practical application of this tool, and application of the DRL concept to newer imaging technologies. This report is intended as a further source of information and guidance on these issues. Some terminology has been clarified. In addition, the report recommends quantities for use as DRLs for various imaging modalities, and provides information on use of DRLs for interventional procedures and in pediatric imaging. It suggests modifications in the conduct of DRL surveys that take advantage of automated reporting of radiation dose related quantities, and points out the importance of including information on DRLs in training programs for health care workers. The target audience for this report is national, regional and local authorities, professional societies, facilities where ionizing radiation is used for medical purposes, and responsible staff within these facilities. A full set of the Commission’s recommendations is provided.

Please send your comments to Lynne Fairobent at lynne@aapm.org on the attached Excel spreadsheet no later than April 1st, so that they can be consolidated as AAPM comments. Please be sure to include page and line number as the ICRP did not do continuous line numbering.

NCRP Requests Comments on Draft Lens of the Eye Commentary

The draft NCRP commentary prepared by SC 1-23 on “Guidance on Radiation Dose Limits for the Lens of the Eye” is now ready for review.This Commentary has been prepared in order to provide guidance on whether existing 3 dose limits to the lens of the eye should be changed in the United States. The guidance is based on a detailed evaluation of recent studies on the radiation dose response for the development of 5 cataracts.

Please focus your comments on substantive (e.g., technical errors, references that are not included and incomplete or incorrect interpretation of data) rather than editorial problems in the draft commentary. If you have suggestions for changes or additions to the text, please indicate clearly how your recommendations should be addressed by the committee in preparing the final revision of the commentary.

If you would like to have AAPM consider your comments, please send your comments to Lynne Fairobent at lynne@aapm.org on the attached excel spreadsheet by March 1st in order that I can consolidate them for AAPM's submittal. NCRP comment period closes March 9th.

NRC Requests for Information Regarding I-131 Patient Release.

On December 14, 2015, NRC Issued Regulatory Issue Summary 2015-18 Sodium Iodide-131 (I-1310 Patient Release Information Collection

The NRC is interested in obtaining input from as many stakeholders as possible, including the physicians, the NRC and Agreement State medical use licensees, and NRC MML medical use permittees that administer I-131 under the provisions of Title 10 of the Code of Federal Regulations Part 35 (10 CFR 35.300) or equivalent Agreement State requirements. The NRC is also interested in obtaining input from Agreement States. In addition to the recipients of this RIS, the NRC will also be seeking input from patients, patient advocacy groups, professional organizations, and other interested individuals. The focus of this information-gathering effort is to obtain: information that patients believe will help them understand the I-131 (also referred to as Radioactive Iodine (RAI)) treatment procedures, the physician’s or licensee’s/permittee’s best practices when making informed decisions on releasing RAI treatment patients, and information provided to patients on how to reduce radiation doses to others. The NRC is also interested in learning if patient advocacy groups, medical professional organizations, licensees, or other individuals have brochures that already contain the information requested.

The NRC published the “Sodium Iodide I-131 Patient Release Information Collection” FRN to reach as many stakeholders as possible. In the FRN, the NRC staff requested that stakeholders provide the NRC with information that they already possess concerning: (1) Web sites that provide potential patients with information on RAI treatment procedures so that patients will understand the reason for the procedures, the process, and how to reduce radiation exposure to others; (2) patient/licensee acknowledgement forms and best practices that focus on the dialog used by physicians/licensees and patients that ultimately results in the informed decision, based on radiation exposure considerations, on when the patient should be released; (3) guidance for released patients that helps to reduce the variability of instructions provided to patients and to eliminate some of the uncertainty regarding the type of information that is provided to the patient; and (4) an existing brochure for nationwide use that licensees and Agreement States believe provides clear guidance on the release of patients treated with I-131.

To aid all stakeholders, in the FRN NRC staff provided suggested topics or questions related to the information the stakeholders will submit on the Web site, in the patient/licensee acknowledgement forms, in guidance for released patients, and in a brochure for nationwide use. Because these topics and questions are probably incomplete, the NRC staff also requested that stakeholders, based on their personnel experience, identify any additional topics and questions that they believe should be included in these lists and any that they believe should be omitted from these lists. The NRC is not requesting the development of new information or that individuals research any of the topics presented in the FRN. Greater detail on the information requested and how to submit it is provided in the FRN. The NRC is also requesting that Agreement State and NRC medical use licensees, as well as NRC MML medical use permittees, voluntarily share the FRN with their staff associated with the administration of sodium iodine I-131. As noted in the FRN, this information should be submitted by February 16, 2016. The FRN is enclosed or can be accessed on the electronic Federal Register page.
