The difference between tracking and inventory management are substantially different and seems to be a confusing topic in healthcare, especially within the instrument tracking world.
We will try provide a simple explanation:
Assets are defined as an economic resource that represents an ownership of value, this could be an ambulance, a piece of software or, yes, even surgical instruments.
Inventory is a list of compiled assets for sale or use in another process.
For example, think of a book store and the public library. The book store keeps count of the stock needed to generate sale profits and the re-stocking of books and magazines for sale.
Tracking is like the public library. They need to know where the books are, who has them checked out, who checked the book out three months ago or a year ago, keeping history of names, phone numbers and different locations where the book moved.
Inventory management is a good tool if the healthcare facility plans to buy and sell instruments so they can study cost,profit and re-stocking, etc...
But tracking is having complete knowledge and control over the history, location and anatomy of each single instrument inside a tray or inside a set within the entire supply chain.
The best practice for instrument tracking is not only knowing where each piece is at some point in time, but to be able to build a history of that point in time for future review.
