There’s a name for what’s happening: OR capacity leakage. It’s the cumulative loss of usable surgical time that doesn’t show up in standard reporting. Think about a typical day. The first case starts late. Every case behind it absorbs that delay. A slow turnover adds another fifteen minutes to a room already running behind. An add-on that should have fit the afternoon block doesn’t, because the block was released too late. Two rooms are scheduled to run simultaneously, but anesthesia coverage can’t support both, so one sits idle until the other finishes. None of it gets coded as a cancellation. All of it costs time.

Individually, these situations feel manageable. Across a full schedule and multiple rooms, they can erase hours of surgical capacity every week.
 

Where the Time Goes

Capacity leakage comes from several places at once, and they compound.

First-case delays are the most visible. When the first case starts late, everything behind it absorbs that delay. High-performing organizations target a first-case on-time start rate of 90 percent or higher. Most fall short, and the effect moves through the rest of the day whether anyone tracks it or not.

Turnover time is where leakage is often hardest to see. A turnover that runs ten minutes longer than planned, across multiple rooms, multiple times a day, adds up to significant lost time — none of which gets coded as a delay or a cancellation.

Staffing gaps create a different kind of problem. The 2025 OR Manager Career/Salary Survey found that slight staffing improvements from 2024 were short-lived, with open positions for RNs and surgical techs increasing again. A room without the right staff to run it isn’t an available room at all.

Anesthesia concurrency refers to the simultaneous management of multiple active cases by a single anesthesia provider. It rarely surfaces in standard metrics, but it creates real drag. When coverage can’t support overlapping rooms, cases get delayed without anything showing up on the board itself.

Instrument and equipment readiness is where the day can quietly unravel. A tray that isn’t ready, a vendor who arrives late, a preference card that doesn’t match what’s in the room — any of these can hold a case at the start or slow a turnover mid-stream, and the effect carries forward.

What Traditional Metrics Miss

Most OR performance dashboards track what’s easy to measure, first-case on-time starts, turnover times, cancellation rates, block utilization by surgeon or service.

What they often don’t capture is the cumulative drag of smaller delays — the kind that never meet a threshold for a formal delay code, but still drain time from the day.

A March 2026 Becker’s Hospital Review piece featuring eight perioperative leaders on hidden OR capacity challenges surfaced exactly this pattern. Leaders pointed to block scheduling inefficiencies, underutilized swing rooms, and delays that fall outside the windows traditional metrics are designed to catch. The consistent theme: first-case starts and turnover times tell part of the story, not all of it.

Closing the Gap

Reducing capacity leakage requires viewing the OR as a system in which staffing, scheduling, instrument readiness, anesthesia coverage, room setup, and turnover all affect one another.

Perioperative leaders working on this problem tend to focus on a few areas: team huddles, preference card accuracy, consistent delay codes so patterns can be identified, and staffing model reviews that ask whether current structures can support the volume being scheduled on a normal day, not just a good one.

The cases being lost to capacity leakage won’t show up on a regular report — but they’re real, they’re recurring, and in most ORs, they’re recoverable.

Skytron has spent more than 50 years working alongside OR teams in rooms of every size and complexity. We know that running a surgical program well is about more than how many rooms are on the schedule.
