Radiation Dose Audit Reports to Reduce Radiation Exposure From CT Exams

NCT01405066 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 19

No results posted yet for this study

Summary

The purpose of this study is to quantify variation in radiation dose levels across CT technologists, and determine the effectiveness of combining radiation dose audit reports and an educational seminar as a means to reduce the variation and level of patient exposure to radiation.

The investigators expect the radiation dose audit reports and educational seminar will lead to reduced radiation exposure to patients by making technologists more aware of the risks of radiation exposure from CT exams and identifying technologists with higher radiation exams compared with their peers.

The investigators expect the degree to which a technologist is concerned and aware about radiation exposure and cancer risk will be associated with adherence to radiation reduction protocols and the subsequent level of radiation their patients are exposed to when receiving a CT examination.

Conditions

  • Decrease Variability and Amount of Radiation Dose From CT Exams

Interventions

BEHAVIORAL

Radiation Dose Audit Reports

Audit reports by CT technologist, with graphs of radiation dose levels of 20 exams from each of the 4 most common CT exams. Reports show the distribution of radiation dose levels by each exam type, and compares the technologist's dose levels to the overall levels from the clinic where they work and to the United Kingdom's 2003 Reference Dose. Prior to the graphs, the reports include an introductory page explaining the organization of the report and defining the dosimetry metrics. The final page of the report lists exams meriting individual review because their doses are higher than that of the clinic averages.

BEHAVIORAL

Educational Seminar: Radiation Dose Reduction

Seminar led by a Radiologic Physicist and Radiologist. Discussion of the parameters associated with radiation dosage from CT exams and methods for changing these parameters to lower radiation dose.
