Joint Statement ASRT Practice Standards


 The American Society of Radiologic Technologists (ASRT) recently posted medical dosimetry practice standards for public comment. The AAMD and the MDCB, together, collaborated on a response to the ASRT regarding the posted practice standards. The response is outlined below.


Joint Statement of the AAMD and the MDCB on ASRT Practice Standards

The American Association of Medical Dosimetrists (AAMD) and the Medical Dosimetrist Certification Board (MDCB) recently reviewed the American Society of Radiologic Technologists (ASRT) Practice Standards posted for public comment. Both organizations are concerned that the standards as stated, both text highlighted for change and text not highlighted for change, do not adequately reflect the medical dosimetry profession. We find the language to be dated and not accurately indicative of current medical dosimetry practice.

To alleviate confusion, there should be one standard for any profession. This standard is the standard developed by the professional medical dosimetry society, the AAMD, as referenced in the AAMD Scope of Practice. The Scope of Practice has been thoroughly researched. It identifies the basic responsibility of the “Qualified Medical Dosimetrist” and “addresses education, certification, continuing education and maintenance of certification.” In addition, the Scope of Practice is designed to educate professionals in the fields of health care, education, other communities of interest and the general public regarding the expectations of the Qualified Medical Dosimetrist. One of its intended uses is for “individual facilities to develop job descriptions and practice parameters.”

The AAMD Scope of Practice is the basis of the AAMD Curriculum Guide, which is endorsed by the Joint Review Committee on Education in Radiologic Technology (JRCERT) and followed in the development of JRCERT accredited medical dosimetry educational programs. Graduation from a JRCERT accredited program is the only vehicle through which a medical dosimetrist can achieve certification in medical dosimetry.

Certification in any field represents a recognized standard of knowledge and education and measures knowledge in a standardized and comprehensive way. Both the American Society for Radiation Oncology (ASTRO) and the American College of Radiology (ACR) recognize MDCB Certification, a certification based on the AAMD Scope of Practice, as a significant aspect for the medical dosimetrist on the radiation oncology team.

Patient safety and consistent quality of care is a recognized touchstone of all three (3) organizations –  AAMD, ASRT and MDCB – as referenced in each of their individual mission statements. Quality patient care can only result from clarity by adherence to one definitive standard. The standard for medical dosimetry is the one developed by the professional society dedicated to medical dosimetry – AAMD – and is the one on which medical dosimetry certification is predicated. Medical dosimetry certification by the MDCB is recognized by authorities in the radiation oncology field – ASTRO, ACR and JRCERT.

The AAMD and MDCB respectfully request that the ASRT adopt the AAMD Scope of Practice as the definitive scope of practice for medical dosimetry.
