ABSTRACT

BACKGROUND: We examined utilization patterns and predictors of computed tomography pulmonary angiography (CTPA) results in the emergency department (ED).

OBJECTIVES: We retrospectively determined ED CTPA positive scan rate (PSR) among ED attendings based on a system that grouped attendings into scan quantity categories through >100.

METHODS: We manually reviewed all scans ordered in 2017 in EDs in a multisite medical system.

RESULTS: Of 10,032 ED CTPAs, 6168 were ordered by 153 ED attendings. Most attendings (123/153; 80%) ordered 60 or fewer scans with relatively high PSR (259/2927, PSR 8.8%; 95% confidence interval 7.8-9.9%). Of the ED attendings, 13 (3%) ordered more than 100 scans each (1981 scans; 32% of all scans), with PSR of 5.5% (95% confidence interval 4.5-6.5%).

CONCLUSION: Most ED attendings were low- to mid-volume utilizers of CTPA and had a relatively high PSR. However, the small percentage of attendings who ordered more than 100 scans each accounted for a large percentage of the total scan volume and had a relatively low PSR. These findings suggest that sharing of performance feedback and best practices in the highest utilizers could help to improve CTPA PSR in the ED.
