Purpose.

To evaluate the effectiveness of the checklist in radiological practice in patients with severe combined trauma on CT.

Materials and methods. In total, the study analyzed 172 CT examinations using the “whole body” technique from the number of patients with severe combined trauma who were admitted to the emergency hospital from 05/01/2018 to 01/28/2019. Patients were divided into two groups: without checklist and with using it. The first group of patients without a checklist included 85 people. Of these, 59 (69.5%) are men and 26 (30.5%) are women. The average age in the group was 42.2 (CI 38.9; 45.4) years. The second group of patients with a checklist included 87 people. Of these, 60 (69.0%) are men and 27 (31.0%) are women. The average age in the group was 38.9 (35.5; 42.4) years.

Results. The probability of a clinically significant error in the group without a checklist was 22.4% (СI 95%, 14.2: 35.0), the probability of a clinically significant error in the group without a checklist was 5.7% (СI 95%, 2.4: 13.8). The proportion of the difference between the groups of patients using the checklist and without it was 74.6%, which indicates a significantly pronounced reduction in the risk of a clinically diagnostic error when using the checklist. The relative risk (in how many times the number of errors decreased) was RR = 3.89 (CI 95% 1.52: 9.94).

Conclusion. Using of a checklist in the working practice of a radiologist statically reduces chance of a diagnostic error.
