Case complexity is Theator's measure of how challenging a procedure was, shown as a single labeled grade on the case page. It lets you tell a routine case apart from a difficult one at a glance, compare cases, and give context to metrics like duration when you review your performance.
What case complexity means
Complexity is expressed on a five-level scale. Each case with a grade is placed on one of these levels:
| Level | Label |
|---|---|
| 1 | Low |
| 2 | Moderate |
| 3 | Considerable |
| 4 | High |
| 5 | Extreme |
A higher level means Theator identified more of the factors that make a procedure harder to perform.
How Theator calculates it
Theator derives the complexity grade from procedure-specific clinical factors assessed for each case. The factors that matter depend on the procedure — for example, the presence of adhesions, inflammation, the size of a lesion, or anatomical variations relevant to that operation. These factors are evaluated and mapped to one of the five levels above.
Because the factors are specific to each procedure, complexity is currently available for cholecystectomy, appendectomy, partial nephrectomy, and complete nephrectomy. A grade appears only when Theator has enough information to calculate one for that case. Cases without a grade simply do not show a complexity value.
Where you see complexity in the platform
When a case has a complexity grade, it appears as a Complexity badge, with a gauge icon, in the case information panel on the case page. The badge shows the level's label (for example, Considerable) so you can read the grade without leaving the page.
If you do not see a Complexity badge on a case, the procedure type is not in the supported list above, or no grade is available for that specific case.
