BACKGROUND: An upcoming national mandate will require consultation of appropriate use criteria (AUC) through a clinical decision support mechanism (CDSM) for advanced imaging. We aimed to evaluate our current ability to ascertain test appropriateness.
METHODS: We prospectively collected data on 288 consecutive stress tests and coronary computed tomography angiography studies for medical inpatients. Study appropriateness was determined independently by two physicians using the 2013 Multimodality AUC.
RESULTS: The median age of the study population was 66 years [interquartile range (IQR) 56, 75], 40.8% were female, and 52.8% had a history of coronary artery disease. Review of the electronic health record (EHR) alone was sufficient to deem appropriateness for 87.2% of cases. The most common reason it was insufficient was inability to determine if the patient could exercise (59.5%). After reviewing the EHR and pilot CDSM data together, appropriateness could be determined for 95.8% of the cases. The most common reason appropriateness could not be determined was that the exam indication was not addressed by an AUC criterion (83.3%).
CONCLUSION: In preparing for the mandate, it will be important for future CDSM to obtain information on the patient's ability to exercise and for future AUC to include additional indications that are not currently addressed.
