Statistics that fail independent corroboration are excluded.

In 2025, Operating Room statistics show a sharp mismatch between what surgical teams plan for and what actually happens once cases start moving. When you compare procedure turnaround times, staffing pressure, and documentation completeness side by side, the pattern gets hard to ignore.
