Total cost of ownership of surgical instruments: the complete guide

Short answer: The purchase price is only part of an instrument’s cost. Total cost of ownership adds reprocessing for every use, repairs, losses, replacements and the cost of delays when instruments fail. Better instruments often cost less over their life.

Parts of total cost

• Purchase: Price paid
• Reprocessing: Cleaning, packing, sterilising each cycle
• Repairs: Sharpening, realignment, inserts
• Losses: Missing instruments
• Replacement: End of life
• Downtime: Delays when instruments fail

Calculating cost per use

1. Purchase price
2. Divide by expected uses over life
3. Add reprocessing cost per use
4. Add repair cost per use
5. Add loss and replacement allowance
6. Compare options per use

Example

	Cheaper needle holder	Better TC needle holder
Purchase	Lower	Higher
Expected life	Short	Long
Repairs	Replace often	Insert replacement
Cost per use	Often higher	Often lower

Data to collect

• Purchase prices
• Uses per year
• Reprocessing cost per set
• Repair costs
• Loss rates
• Replacement frequency

In detail: the hidden cost of failure

When an instrument fails during surgery, the cost includes delay, stress and sometimes extra sets opened. These costs are hard to measure but real.

Worked example

A hospital compares two suppliers of scissors over three years. The cheaper scissors need replacing twice as often; total cost per use is higher than the better scissors.

Proof box

Proof: Health economics and procurement guidance recommend whole-life costing instead of purchase price alone for durable medical equipment.

Frequently asked questions

How long does an instrument last? Many years with good care.

Is single-use cheaper? Sometimes, at low volumes.

What is the biggest hidden cost? Often reprocessing labour and failures.

How can I reduce costs? Lean sets, good care, timely repair.
