Minimizing Medical Radiation Exposure by Incorporating a New Radiation "Vital Sign" into the Electronic Medical Record: Quality of Care and Patient Safety.

There is a clearly perceived and imminent need to decrease unnecessary and detrimental exposure to medical ionizing radiation. We propose a new radiation "vital sign" that incorporates cumulative radiation exposure to create a risk score on the basis of an individualized assessment of potential harm from additional exposure to medical radiation. We propose to then tie the risk score to real-time, evidence-based, clinical decision support for procedures that use ionizing radiation. Additionally, we offer recommendations that minimize unnecessary or low-yield uses. Preference is given to approaches and modalities that use less or no ionizing radiation and that are medically appropriate, acceptable to, and safer for patients.
