Radiation Dose Audit Reports to Reduce Radiation Exposure From CT Exams
CT Technologists Dose Audit Reports and Educational Seminar to Reduce Patient Radiation Exposure From Medical Imaging
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.

EXPERIMENTAL: Dose Reports and Educational Seminar
|
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.
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.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Radiation dose levels (measured by dose linear product (DLP) and effective dose (ED)) from CT exams as a measure of the effectiveness of radiation dose audit reporting and educational intervention for lowering patient exposure to radiation from CT exams.
Time Frame: April 2011 and September 2011
|
We will report dose data at two time points, April 2011 (data for these reports collect from November 2010 to March 2011), and September 2011 (data collected from April 2011 to August 2011), and compare the data from the two time points to see if there was a change in dose levels (DLP and ED) for the time period (April to August) after the presentation of the first audit reports and delivery of the educational interventions to the CT technologists.
