Transforming the Imaging Experience While Decreasing Sedation Rates.

Abstract

To evaluate the effect of the MRI-am-a-Hero program on sedation utilization for outpatient pediatric MRI studies. The MRI-am-a-Hero program, which utilizes multimedia educational material and popular comic book characters to educate and support pediatric patients during MRI scan, was implemented at the radiology facility of a single tertiary care, academic medical center. The effect of the MRI-am-a-Hero program on sedation utilization for pediatric MRI was retrospectively evaluated using multivariate regressions yielding odds ratio of sedation before and after program implementation. The institutional review board approved the study with HIPAA compliancy. Effectiveness of the program was evaluated while controlling for age, neurological MRI examination, number of examinations in the case, and use of intravenous contrast. Further analysis was performed in subgroups categorized by age, neurological MRI versus nonneurological MRI, and the use of contrast. The percent of MRI cases with sedation decreased from 22.9% to 17.3% after the MRI-am-a-Hero program was implemented. When controlling for other variables, including patient age, neurological MRI, number of examinations in a case, and use of intravenous contrast, the odds of a study being performed with sedation after program implementation are 40% less than the odds before program implementation (odds ratio [OR] 0.60, P < .001). The effect of the program was greatest for patients aged 4 to 7 (OR 0.56, P < .001), followed by patients aged 8 to 11 (OR 0.64, P = .019). It was not statistically significant for patients aged 12 to 15 (OR 0.97, P = .919). MRI-am-a-Hero is a generalizable and inexpensive program for reducing sedation utilization for outpatient pediatric MRI studies, especially for patients aged 4 to 11.
