Reusable vs Single-Use Surgical Instruments

Why unit price is the wrong comparison

A low purchase price can hide processing or replacement costs, while a higher unit price can hide waste or inventory exposure. Set the comparison boundary before collecting numbers.

Map the full reusable-instrument lifecycle

For reusable instruments, record acquisition, decontamination, inspection, packaging, sterilization, storage, repair, loss and replacement using local measured inputs wherever possible.

Map the full single-use lifecycle

For single-use supply, include purchase, receiving, storage, case picking, unused opened items, disposal and any product- or market-specific handling requirements.

Include availability, loss and operational resilience

Model shortages, urgent replenishment, damaged reusables, lost instruments and supplier interruption as explicit scenarios. Operational resilience should not be buried inside an average unit cost.

Evaluate waste and logistics honestly

Compare waste streams and transport assumptions consistently without assigning unsupported environmental scores. State which data are measured, estimated or supplied by another party.

Build a local decision model with sensitivity ranges

Build low, expected and high cases for volume, labour, loss, repair and disposal. A sensitivity table shows which assumptions actually change the decision and where better evidence is worth collecting.

Putting the guidance into practice

A defensible comparison exposes its boundary, data sources and uncertainty.

Use the result to identify the few local variables that matter most, then update the model when measured evidence improves.
