Cumulative radiation exposure shows increased cancer risk for emergency department patients

According to a new study, patients are receiving estimated doses of radiation from medical diagnostic imaging studies, such as CT (or CAT) scans, that may be detrimental to their long term health, putting them at an increased risk of developing cancer. To date, emergency physicians have not been made aware of the cumulative amount of radiation that their patients receive. In fact they currently have no way to know or estimate any given patients cumulative dose. A new study hopes to quantify and further explore these concerns.

Led by Timothy B. Bullard, M.D., M.B.A of the Orlando Regional Medical Center (ORMC), the cross-sectional study examined the amount of ionizing radiation that a random selection of patients received over a five-year period at ORMC and Washington Hospital Center in Washington, D.C. The study is the first to estimate the total cumulative radiation dosage delivered to a population from multiple diagnostic imaging modalities during a defined period of time.
