Distribution of diagnostic outcome for recommendations that were followed, that were not followed, and for which it remained unclear whether the recommendation was followed (n = 136)a
| Followed (%) | Not Followed (%) | Unknown (%) | Total (%) | |
|---|---|---|---|---|
| Benign | 44 (84.6) | 6 (11.5) | 2 (3.8) | 52 (100.0) |
| Malignant | 21 (75.0) | 5 (17.9) | 2 (7.1) | 28 (100.0) |
| Unknown | 24 (42.9) | 31 (55.4) | 1 (1.8) | 56 (100.0) |
↵a Because some reports contained 1 recommendation asking to check on 2 different structures, the total number is higher than the total count of recommendations (eg, 1 MR imaging focused on the orbits and 1 MR imaging focused on the cerebellopontine angle). The diagnostic outcome was defined as having established either a benign or a malignant diagnosis for a perceived lesion based on the results of the recommended additional diagnostic tests, which clarified perceived lesion nature, or on the second opinion report itself if it already provided a definitive diagnosis.
