Purpose: While several studies analyze radiology malpractice lawsuits, none specifically examines the site of service. The purpose of this study is to estimate the relative likelihood of a lawsuit arising from a radiology study performed in emergency (ED), inpatient (IP) and outpatient (OP) settings.
Methods: Referrals from a malpractice review consulting company over a six year period were compared to the 2016 Medicare Part B file and stratified by site of service. The proportion of exams for each site of service was estimated, and using absolute differences in proportions and odds ratios (ORs), differences in the place of service were calculated.
Results: The Cleareview cohort contained 25 (17%) IP, 56 (38%) OP, and 68 (46%) ED exams. In 2016, Medicare assigned benefits for 27,009,053 (20%) IP, 84,075,848 (62%) OP and 23,964,794 (18%) ED exams. The ORs (Cleareview: Medicare) of the ED to IP, OP, and IP+OP were 3.07 (95% CI: 1.56-6.03), 4.26 (95% CI: 2.76-6.59), 3.89 (95% CI: 2.60-5.83), respectively. By contrast, the OR for IP:OP between Cleareview and Medicare was not significantly different than 1 (OR: 1.39, 95% CI: 0.68-2.83, P = .38).
Discussion: Radiological studies performed in the ED accounted for a disproportionate number of liability claims against radiologists. Further study is warranted to confirm this finding with a more robust data set.
