Optimizing Patient Exposure to Ionizing Radiation: Count of Potential High Dose
Percentage of computed tomography (CT) and cardiac nuclear medicine (myocardial perfusion or infarct avid imaging) reports for all patients, regardless of age, that document a count of known previous CT (any type of CT) and cardiac nuclear medicine (myocardial perfusion or infarct avid imaging) studies that the patient has received in the 12-month period prior to the current study.

📖Clinical Rationale
Increased CT use has resulted in growing rates of repeat or multiple imaging. Physicians may lack important information that could inform their decisions in ordering imaging exams that use ionizing radiation. Ordering physicians may not have access to patients’ medical imaging or radiation dose history. Due to insufficient information, physicians may unnecessarily order imaging procedures that have already been conducted.
📝Clinical Recommendations
Radiologists, medical physicists, radiologic technologists, and all supervising physicians have a responsibility to minimize radiation dose to individual patients, to staff, and to society as a whole, while maintaining the necessary diagnostic image quality. (Gunderman, et al., 2008)
📋Implementation Notes
This measure contains one strata defined by a single submission criteria. This measure produces a single performance rate. For the purposes of MIPS implementation, this procedure measure is submitted each time a procedure is performed during the performance period.
