A new operating theater is rarely costed correctly at procurement. Hospitals price the headline items — table, lights, anesthesia machine, electrosurgical generator, monitor — and then under-budget by 30–40% on the costs that emerge over the next five years.
This is a more honest approach.
Purchase: the visible cost
Surgical table. Operating lights. Anesthesia machine. Electrosurgical generator with energy platform. Multi-parameter patient monitor. Surgical microscope or imaging equipment if specialized. Endoscopy tower if minimally-invasive. Standard instrument sets. Crash cart. Stretcher.
A complete general-surgery OR equipment package, refurbished and properly outfitted, lands in the high six figures USD. This is the number procurement teams remember. It's only part of the cost.
Installation: 5–10% of purchase
Site readiness, gas drops, electrical work, network drops, mounting, calibration, electrical safety testing, training. A complete OR commissioning typically runs 5–10% of equipment cost, sometimes more if structural work is required.
Consumables: 10–20% per year
Disposables (drapes, gowns, sponges) are usually procured separately, but equipment-specific consumables shouldn't be. Anesthesia circuits, vaporizer fills, ECG cables, SpO2 sensors, electrosurgical pads, suction tubing, ICG dye for fluorescence laparoscopy, scope reprocessing chemistry, recorder media. Add up the per-case consumable cost and multiply by case volume.
A high-volume OR doing 1500 cases/year with full minimally-invasive capability easily spends 15–20% of equipment value annually on consumables.
Maintenance: 8–12% per year for comprehensive
Manufacturer service contracts for OR equipment run roughly 8–12% of purchase price per year for comprehensive coverage. A budget-conscious approach using PM-only contracts plus paid corrective service can drop this to 5–7% — at the cost of higher variability and longer downtime when corrective work is needed.
Critical equipment — anesthesia machines, ventilators, ESU generators — should not be on break-fix.
Training and turnover: 2–3% per year, in steady state
A high-turnover OR loses staff. New staff need training on the equipment. Refresher training when software updates change workflows. Specialist training when new procedures are introduced. Budget realistic training spend annually, not just at install.
Repair vs. replacement: known unknowns
Beyond contracted maintenance, things break that aren't covered. A surgical light arm collapses. A microscope objective cracks. A scope is dropped and bent beyond repair. Realistic OR equipment budgets include a 3–5% per year contingency for un-contracted repair and accelerated replacement.
End of life: another major capital cycle
Refurbished equipment buys 8–12 years of service life. New equipment, 12–15. Plan the next replacement cycle from day one. The OR you're equipping today will be re-equipped within 15 years; the budget needs to anticipate it.
Five-year total
A complete refurbished OR with comprehensive service runs roughly 2.0–2.5x the purchase price over five years when consumables, maintenance, training, and repair are added correctly. The procurement that promised "OR equipped for X" is, in operating reality, OR equipped for 2X over its first 5 years.
This is not a problem if budgeted correctly. It is a serious problem when only the headline number was budgeted — and the operating reality emerges over years one through three as unexpected line items.
The right approach: cost the OR honestly at procurement, with all five line items (purchase, install, consumables, maintenance, training) modeled as a five-year P&L. Then make the procurement decisions in the context of that full picture, not the headline number alone.
