Background Approximately one-third of additional imaging for trauma consults results in the discovery of new injuries. No studies have addressed the perception of these findings in non-health care providers. Our hypothesis was that significant differences in perception of the importance of injuries would exist between health care providers (HCPs) and the general population. Methods Six standardized scenarios were developed detailing common new injury findings on additional imaging in trauma consults. Demographics as well as information regarding the significance of findings, potential for change in care, and the importance of patient notification were collected. Surveys were electronically distributed to HCPs in our system and the public. Data analysis was performed with generalized linear modeling. Results A total of 339 public and 129 HCP surveys were returned. HCPs included attending staff, residents, and advanced care providers from a variety of specialties. Significant differences in perception were found in traumatic brain injury, spine fractures, and rib fractures, with HCPs rating most findings as less clinically important than the general population, while rating patient notification as more important. Perceived importance decreased with increased age in the general population. Increasing HCP age or length in practice did not significantly affect perception of clinical importance, except for rib fractures. Discussion Differences in perception exist regarding the significance of additional injuries between HCPs and the general population. Perceptions of the general population also change with age. Decisions to pursue additional imaging in trauma patients should include consideration of these differences in perception to help support quality patient-centered care.
