The operational benchmarks that actually move ASC margin

Surgery centers generate an enormous amount of measurable activity, and it is easy to build a reporting package that describes a center in detail without changing how it runs. A smaller set of measures does most of the work.

Room turnover time is the most visible, but first-case on-time starts have a larger downstream effect: a late first case delays every case behind it and pushes staff into overtime at the end of the day.

Supply cost per case, tracked by physician and by procedure, surfaces preference-card drift faster than any aggregate supply budget. Most centers find meaningful savings in items that were added to a card years ago and are opened but never used.

On the revenue side, days in accounts receivable and clean claim rate tell you whether the business office is keeping pace with volume. A rising denial rate in a single procedure family almost always traces to a coding or authorization process that can be corrected in weeks.

The point of the short list is that each measure has an owner and a specific corrective action. Metrics without either are reporting, not management.
