GIGO applies here, but with much greater consequences. Conversely, good information in results in more valuable consultation out in the form of the Radiology reports. See this article for how the authors “found improvement in quality of histories provided on requisitions for unenhanced head CT after a fairly simple intervention in the ED. In addition to aiding interpretation, improved clinical information significantly reduced time in receiving payment for the studies.” This results in a “win” for all, including likely improved quality of care for patients.
This article illustrates two key points:
- CT information is particularly impactful in the ER environment where they need correct diagnoses quickly in order to initiate therapy and triage patients safely from crowded facilities.
- Dual energy CT provides incremental diagnostic information in the ER setting but without any incremental radiation dose – so using it routinely for certain indications may be effective.
