Annual data from 2021 and 2022 were compared using the business intelligence tool.
In 2021, a total of 44,274 CT scans were performed, of which 35,388 (80%) were performed with a standard number of series, 3,156 (7%) with a non-standard series, and 5,730 (13%) without an identifier (not mapped, missing RPID).
In terms of dose, 26,359 (59%) examinations were performed below the organizational DRLs, 14,360 (32%) exceeded DRLs, and 3,590 (8%) did not have a reference value.
After observing the data, inappropriate protocols were eliminated or modified in order to achieve a more optimal dose performance. The unification of the protocols helped to avoid unnecessary irradiation scans.
In 2022, we thus achieved the following results:
We performed 47,298 CT examinations, of which 39,637 (84%) were performed with a standard number of series, 3,004 (6%) with a non-standard series, and 4,657 (10%) without an identifier (non-mapped examination).
Regarding dosimetric indices, 30,358 (64%) studies were performed with optimal dose performance, 12,524 (26%) studies exceeded DRLs, and 4,427 (9%) did not have a reference value. If we correlate the 2022 results to the 2021 base year the net number of examinations performed with optimal dose levels increased 2214.
