Purpose To design, implement, and measure outcomes of a technologist education program about anaphylactoid reactions to contrast media. Methods Radiologic technologists viewed a 45-minute presentation and completed a pretest, posttest, and self-assessment. These steps were repeated 14 months later with different test questions. Statistical analysis included participants' t test to assess significant differences (P <.05) between pretests and posttests. Results Seventeen computed tomography (CT) technologists participated in the first educational program, and 19 CT technologists participated in the second session. A statistically significant improvement (P <.05) was found between pretest and posttest mean test scores. However, the pretest scores were lower before the second session. Using a Likert scale (1 = completely agree vs 5 = completely disagree), technologists indicated the session improved their knowledge (mean score 1.1), made them more comfortable managing a reaction (mean score 1.1), and fostered confidence in recognizing symptoms of a reaction (mean score 1.4). Discussion A didactic curriculum of managing anaphylactoid reactions to contrast media offers subjective benefits and short-term objective knowledge gain for CT technologists. After the training, technologists had increased knowledge of and comfort with managing an emergency situation and recognizing symptoms, which help to prevent morbidity and mortality. However, the results indicate that frequent repetition of the material is necessary for long-term gains. Conclusion A dedicated educational program for technologists helps prevent and manage adverse reactions to contrast media through improved knowledge, increased comfort and confidence, and teamwork development. At a minimum, semiannual training sessions should occur for all technologists to retain knowledge.
