What Outdated Surgical Preference Cards Cost — and How to Keep Them Accurate
A surgical preference card is the per-surgeon, per-procedure list of instruments, supplies, and equipment an operating-room team uses to set up a case. When it's accurate, the room is ready; when it drifts out of date, the cost shows up as wasted supplies and case-setup mismatches.

What is a surgical preference card?
A preference card is the operating room's reference for a procedure — it tells the scrub tech and circulator exactly what to pull, open, and have ready for a given surgeon and operation. Cards are built once and meant to be maintained, but maintenance is manual, so they drift as surgeons change technique, products get substituted, and experienced staff (and the undocumented knowledge they carry) move on.
What outdated cards cost
A 2025 quality-improvement study in JAMA Surgery (Perez et al., UC San Diego) measured a mean of $1,294.41 per case in unused, opened preference-card items — supplies pulled and opened because the card called for them, then discarded — totaling $3.7M across the cases studied. The figure is specifically unused opened items, not total supply spend.
The pattern is consistent with what frontline staff report. In a self-selected online survey ScrubStack conducted in 2026 of 45 perioperative practitioners (surgical technologists, RN circulators, first assists, and OR leadership) across 25 U.S. states, the most-cited cause of a wrong case setup was an out-of-date preference card. (A directional discovery survey — a self-selected sample, not a population estimate.) In the same survey, only one of the 45 respondents said they would set up a case from the preference card alone; the rest reported supplementing it with additional verification.
Why cards drift out of date
The root problem isn't the card — it's the loss and transfer of institutional knowledge in the OR. Consider a concrete case: a veteran scrub tech who knew "Dr. Lee always wants the 30-degree scope and skips the second drape" retires, and that preference was never written on the card. Or a vendor substitutes a product line and the card still lists the discontinued item. Because updates are manual and usually batched into periodic audits, the gap between what's on the card and what the surgeon actually wants widens with every case.
Keeping preference cards accurate — best practices
- Capture changes at the point of care, not in a quarterly audit. Updating after each procedural change or surgeon feedback keeps the card current; batching corrections into periodic manual audits lets error accumulate between cycles.
- Ground every item in a verifiable device identity. Matching each line to its FDA Unique Device Identification (UDI) — using publicly available data such as openFDA — makes the card auditable and reduces ambiguous or duplicate entries. (UDI matching is a data reference, not FDA clearance or endorsement.)
- Flag what can't be verified, transparently. An honest card distinguishes confirmed items from unverified ones rather than presenting a guess as fact.
SurgX is the marketplace umbrella for this work: searchable medical product intelligence, device provenance, and operating-room workflows that need supply data to stay grounded. The ScrubStack preference-card engine captures preference cards from a phone photo, matches items against publicly available FDA UDI records (~4.9M, snapshot verified 2026-05-31), and flags anything it can't verify rather than fabricating a match — producing a preference card grounded in verifiable, transparent device identity.
FAQ
How much does surgical supply waste cost per case? A 2025 JAMA Surgery quality-improvement study (Perez et al., UC San Diego) measured a mean of $1,294.41 per case in unused, opened preference-card items.
What is a surgical preference card? The per-surgeon, per-procedure list of instruments and supplies an OR team uses to set up a case — the room's reference for what to pull and open.
Why do preference cards become outdated? Maintenance is manual and institutional knowledge is lost as experienced staff leave, so cards lag the surgeon's actual current preferences.
How often should preference cards be updated? Best practice is to update after any procedural change or surgeon feedback, rather than only during periodic manual audits.
How do hospitals reduce preference card waste? By keeping cards current at the point of care and grounding items in verifiable device identity, so opened-but-unused supplies fall.
Who is responsible for updating surgical preference cards? Typically OR staff (scrub techs, circulators) and surgical coordinators, often with surgeon input — which is why low-friction, point-of-care updates matter.
