Improving Patient Safety: Effects of a Safety Program on Performance and Culture in a Department of Radiology

Emphasis is being placed on improving the safety performance of the health care delivery system. The purpose of this study was to evaluate the effects of a program on safety performance and culture in a pediatric radiology department. A comprehensive safety program implemented in a department of radiology included error prevention training for all employees, a safety coach program, safety awards, Crucial Conversations training, and operational rounds with radiology leaders. The number of serious safety events (events with deviation from best practice, patient harm, and causation) that in part involved radiology were compared for 2 years after implementation of the program and the previous 2 years (baseline). A U.S. Agency for Healthcare Research and Quality safety culture survey was distributed to radiology employees, and the responses were compared for periods early in the program and after full implementation of the program. Fisher's exact test was used to evaluate for statistically significant differences (p < 0.05) in the survey responses and the frequency of serious safety events. Before introduction of the safety program, radiology contributed to a serious safety event an average of once every 200 days as opposed to once in 780 days after implementation of the program (one event in more than two academic years) (p = 0.37). Improvement was found in all 12 dimensions of the culture survey after implementation of the program. Radiology scored higher than hospital averages in 10 of 12 dimensions of the survey. The safety program had a positive effect on safety culture. Although it is early in the process and proving statistical significance for rare events such as serious safety events is difficult, the mean number of days between serious safety events has increased from 200 to 780. We conclude that the program is having a positive effect on safety performance.
