Reusable or single-use? A decision guide with a cost model

Short answer: Choose based on five factors: procedure volume, reprocessing capacity and cost, infection control needs, instrument performance and sustainability. A simple cost-per-procedure model, using your own numbers, usually makes the answer clear.

The decision in five questions

1. How many procedures per year?
2. Can we reprocess reliably on site?
3. What does reprocessing cost per use?
4. Is a single-use instrument good enough clinically?
5. What is the environmental impact?

A simple cost model

Item	Reusable set	Single-use kit
Purchase per use	Price ÷ uses over life	Kit price
Reprocessing per use	Labour + water + energy + packaging	None
Repairs and losses per use	Allowance	None
Waste per use	Small	Higher
Total per use	Sum	Sum

Fill in your own figures. Volume is usually the biggest driver.

When each wins

• Reusable: High volume with efficient sterile services
• Reusable: Complex procedures and surgeon preference
• Reusable: Lower waste over time
• Single-use: Low volume or no sterilisation
• Single-use: Outreach, emergency and home care
• Single-use: Infection-sensitive settings

Before switching

• Run the cost model
• Test single-use samples with users
• Check storage space
• Check waste disposal
• Plan supply contracts

In detail: mixed models

Many hospitals use both: reusable core sets plus single-use kits for extras. This keeps surgeons’ preferred instruments while saving time on simple items.

Worked example

A day-surgery unit calculates that single-use kits cost slightly more per case than reprocessing, but save theatre turnaround time; it adopts kits for its highest-volume procedure only.

Proof box

Proof: Market data show reusable instruments still held the majority share of instrument sales in 2025, while single-use instruments grow about 5 to 6% a year, reflecting mixed models.

Frequently asked questions

Is single-use always safer? It removes reprocessing risk, but reusable instruments are safe when reprocessed correctly.

Is reusable always greener? Usually less waste, but reprocessing uses water and energy.

Can we change later? Yes, review yearly.

Who should decide? A team including surgeons, nurses, sterile services and procurement.

Glossary

• Cost per use: total cost divided by uses.
• Mixed model: combining reusable and single-use.
• Turnaround: time between cases.

Key takeaways

• Use your own numbers
• Volume drives the answer
• Mixed models often work best
