A decade ago, a strong clinical champion and a compelling product demo could carry a VAC decision. Today, the evidence requirements have ratcheted up to a level that would have been unrecognizable to the medtech sales teams of 2015.
VACs now expect peer-reviewed clinical studies, ideally randomized controlled trials, but at minimum well-designed prospective studies published in credible journals. They expect comparative data: not just “our product works,” but “our product reduces complications by X% relative to the current standard of care.” They expect real-world evidence from institutions comparable to theirs in patient population, case volume, and acuity level.
This shift was driven by several forces converging at once.
Hospital operating margins have been under sustained pressure. The American Hospital Association’s 2025 Cost of Caring report documented rising supply costs, labor inflation, and reimbursement that has not kept pace. When margins are thin, every purchasing decision faces more scrutiny, and “the surgeon wants it” is no longer a sufficient justification for adding cost.
The rise of value-based care models ties into these challenges, further pressuring hospitals to demonstrate that new products offer measurable improvements to patient outcomes, not just additional costs.
Why the Financial Case Is Where Most Submissions Fall Apart
If the evidence bar catches some companies off guard, the financial case is where most of them actually lose. Generic ROI calculators with national average assumptions don’t persuade a committee that reviews dozens of vendor pitches per year. What works is a financial case built on data specific enough to the hospital’s situation that the committee trusts the numbers.
This means starting with the hospital’s current costs in the product category you are addressing. CMS cost reports provide departmental spending data for Medicare-certified hospitals. Combined with publicly available case volume data, you can build a reasonable baseline estimate even before your clinical champion shares internal numbers.
From that baseline, the financial case needs to address total cost of ownership. That includes unit cost multiplied by projected annual volume, implementation and training costs, inventory carrying costs, service and maintenance costs for capital equipment, and any revenue or reimbursement impact.
Research published by the Association for Health Care Resource and Materials Management (AHRMM) estimates that physician-preferred items account for 40-60% of a hospital’s total supply costs. That spending concentration is precisely why VACs exist: to impose discipline on purchasing decisions that were historically driven by individual physician preference rather than institutional cost-benefit analysis.
A product that costs 10% more per unit but demonstrably reduces complications and therefore readmissions (which CMS penalizes through its Hospital Readmissions Reduction Program) can have a net positive financial impact. But you have to build that story with actual numbers, not hand-waving.
What Has Changed About the Clinical Champion in Medical Device Sales
The clinical champion inside the hospital remains the single most important factor in a VAC outcome. No vendor wins a value analysis approval alone. The champion submits the product request, presents the case to the committee, answers clinical questions from peers, and advocates during deliberation, which happens behind closed doors, without the vendor present.
But the champion dynamic has shifted in important ways.
In the old model, any surgeon with volume and influence could push a product through. Today, the ideal champion combines clinical credibility (the committee respects their judgment), direct experience with your product (they have used it during training, at a previous institution, or in a trial), and enough institutional influence to carry a vote. Department chairs and medical directors are obvious candidates, but a well-respected mid-career clinician who consistently participates in committees can be equally effective.
