Ask any surgical services director how their ORs are performing and they’ll almost certainly reach for a utilization report. Ask them what that number actually means, and the answers will vary wildly. Block utilization. Staffed utilization. In-block usage. Prime time efficiency. These terms are used interchangeably, measured inconsistently, and too often siloed from the decisions they should be driving.
This isn’t a data problem. Most health systems have more surgical data than they can act on. It’s an integration problem — a failure to connect the dots between physician block management, staffing patterns, and physical infrastructure into a coherent management system. And nowhere is this gap more visible — or more costly — than in the platform managing the majority of the country’s surgical scheduling: EPIC.
What EPIC Gets Wrong
EPIC’s block management tools are built to answer one specific question: Did this surgeon use their allocated block? It’s a reasonable starting point, but a dangerously incomplete one.
EPIC measures in-block utilization — what happens within the specific time window assigned to a surgeon. What it doesn’t capture is everything else. A surgeon who regularly starts cases before their block opens, runs late into non-prime hours, or opportunistically fills open rooms appears underutilized in EPIC’s view, even when they’re among your highest-volume performers.
The consequences are real. Block recommendations generated from EPIC’s tools can be directly contradicted by how surgeons actually practice. A surgeon with “low” in-block utilization may in fact be generating significant volume — just not in the window EPIC is measuring. Acting on that incomplete data means pulling time from productive surgeons, triggering political conflict, and leaving real revenue on the table.
But the deeper problem isn’t even the metric itself. It’s the window EPIC looks through. Block management is one lever in a complex system — and optimizing that one lever in isolation, without understanding how it connects to staffing, to capital investment, to multi-site demand, and to the rest of the hospital, produces decisions that are locally coherent but systemically wrong. You can have a beautifully managed block schedule sitting on top of a chronically overstaffed OR suite, or a high-performing surgical program starved of the capital investment it’s already earned. EPIC won’t show you either of those things.
The Problem with Isolated Decision-Making
Surgical services is one of the most complex operational environments in healthcare. On any given day, leadership is managing physician relationships and block time politics, staffing schedules across OR, pre-op, and post-op, equipment availability and capital utilization, anesthesia coverage, downstream inpatient bed capacity — and doing it all largely by feel, because no single system connects those pieces into a coherent picture.
The result is predictable: decisions get made in silos. Staffing is adjusted without understanding the volume pipeline. Block time is reallocated without accounting for the staffing implications of that change. Capital investments are made — or not made — without a clear view of whether existing capacity is actually being used. Each decision may be defensible on its own terms. Together, they often work against each other.
This isn’t a failure of leadership. It’s a failure of infrastructure. When the tools don’t integrate the picture, even experienced leaders are flying blind on the decisions that matter most.
A Different Approach: Integrated Surgical Services Capacity Management
Integrated Surgical Services Capacity Management — ISSCM — is built on a different premise: that surgical services performance can only be understood, and only be optimized, by looking at the whole system at once.
ISSCM organizes surgical services decision-making into three interconnected pillars. The first is Physician Relationships — the management of block time, surgical volume pipelines, anesthesia partnerships, and growth opportunities. The second is Staffing Management — right-sizing the workforce, optimizing shift patterns, and aligning staffing to actual and projected demand. The third is Physical Infrastructure and Capital Investment — tracking how OR capacity, specialized suites, robotics, and multi-site resources are actually being used, and understanding the downstream impact of surgical volumes on the rest of the hospital.
What makes ISSCM different from the way most health systems operate today isn’t the individual components — most surgical leaders are thinking about all of these areas already. It’s the integration. Each pillar informs the others. A change in block allocation has staffing implications that need to be modeled before the change is made. A capital investment in a new OR suite should be preceded by honest analysis of whether existing capacity is being fully used. A staffing constraint that can’t be resolved in the short term should immediately trigger a conversation about how block time and prime time need to be adjusted in the interim.
This is not how EPIC is designed to work. And it’s not how most surgical services organizations currently operate. But it’s how the best ones do.
What Changes When You See the Whole Picture
When surgical services leadership has a truly integrated view of performance, the decisions that were once political become analytical. The conversations that were once contentious become straightforward.
Block management stops being a negotiation between administration and surgeons and becomes a transparent, data-driven process — because the data reflects how surgeons actually practice, not just what happens inside a narrow time window. Surgeons who are generating volume outside their blocks get credit for it. Surgeons who have excess allocated time can see that clearly too. Recommendations become harder to dispute because they’re harder to selectively misread.
Staffing decisions become connected to volume reality. When you can see how OR capacity is actually being used across the full day — not just during prime time blocks — you can build staffing models that reflect operational reality rather than historical habit. When the volume pipeline is visible, staffing lead times can be managed proactively rather than reactively.
Capital and infrastructure decisions get grounded in evidence. The case for adding an OR, investing in robotics, or shifting volume to an underutilized site becomes something you can demonstrate, not just argue for. And the risk of over-investing in capacity that isn’t yet needed — or under-investing in capacity that’s already constrained — drops significantly.
And perhaps most importantly, the institution gets a coherent view of how surgical services affects everything else. OR volumes drive inpatient admissions, ancillary utilization, and bed management. Surgical smoothing — the deliberate management of case scheduling to reduce downstream inpatient bottlenecks — becomes possible only when surgical and hospital operations leadership are working from the same integrated picture.
The Bottom Line
EPIC is a powerful platform. But its block management tools were designed to manage blocks — not to manage surgical services. They look through a narrow window and report accurately on what they see. The problem is what they don’t see: the full operational picture that determines whether a surgical program is truly performing, truly growing, and truly using the resources the health system has invested in it.
The data to build that picture already exists in most health systems. What’s missing is the framework to integrate it, and the discipline to manage against the complete view rather than the convenient one.
That’s what ISSCM offers. Not a new metric, not a replacement for EPIC, but a fundamentally different way of understanding — and managing — one of the most important and most complex service lines in the hospital.
