Abstract
Inefficient imaging practices merit renewed attention in preparation for full implementation of the Appropriate Use Criteria Program. This study's purpose is to quantify changes in outpatient brain CT imaging efficiency from 2013 to 2018, including changes in relative efficiency by hospital category. Imaging efficiency data were obtained from the Medicare Hospital Compare website. Summary statistics were calculated for rates of unnecessarily combined brain and sinus CT scans from 2013 to 2018. Relative performance was compared by hospital Medicare payment structure, type of ownership, and affiliation with a radiology residency program. The predictive value of these hospital characteristics on brain CT efficiency was determined using linear regression analysis. From 2013 to 2018, the mean frequency of unnecessarily combined brain and sinus CT scans decreased by 1.82% (95% confidence interval, 1.74%-1.90%). Proprietary and physician-owned hospitals exhibited a higher mean frequency of combined scans than other hospitals in 2013 (P < .001), and government-owned hospitals exhibited a lower mean frequency of combined scans than other hospitals in 2018 (P < .001). Radiology residency-affiliated hospitals exhibited no significant difference in 2013 but exhibited a higher mean frequency in 2018 (difference: 0.45%; 95% confidence interval, 0.29%-0.61%). Critical access hospital status and nonaffiliation with a radiology residency program were the strongest predictors of brain CT efficiency in the regression model. Recent changes in hospitals' relative brain CT efficiency suggest category-specific differences in responsiveness to quality improvement efforts and may foreshadow similar trends under forthcoming initiatives.
