Healthcare Supply Chain KPIs: 12 Metrics Every Hospital Should Track

Every hospital supply chain leader has heard "we ran out again" in a morning meeting. The fix starts with measurement. Healthcare supply chain KPIs turn vague complaints into numbers you can trend, compare and improve.

This guide covers the 12 metrics that give the clearest picture of a hospital or pharmacy supply chain, grouped into four areas. Each comes with a formula and a note on how to use it.

In most industries a stock-out means a lost sale. In a hospital it can mean a delayed operation, a substituted product or a patient transferred elsewhere. At the same time, supplies and medicines are usually one of a hospital's largest costs after staff, so over-stocking and expiry are expensive too.

Good KPIs help you balance both sides:

• Availability: is the right item there when a clinician needs it?
• Inventory health: are we holding the right amount, or tying up cash and losing stock to expiry?
• Supplier performance: do suppliers deliver on time, in full, at the agreed price?
• Cost: are we buying well and spending under contract?

The share of requested items that were not available when needed.

Lower is better. Track it separately for vital items (from your VED classification). One stock-out of a vital item matters more than ten of a desirable one.

The mirror image of stock-out rate: how many requests were filled completely on the first issue.

Higher is better. Measure it for internal requests (wards and theatres to the store) and for supplier deliveries.

How many items had to be borrowed from another facility, bought locally at short notice, or substituted. It's a practical early-warning signal that sits just behind your stock-out rate.

How many times your average stock is used and replaced in a year.

A higher turnover usually means leaner stock. A very high turnover combined with frequent stock-outs means you're running too lean.

How many days of usage you're holding.

Compare days on hand with supplier lead time. Holding 90 days of an item with a 7-day lead time is usually a sign of over-stocking.

The value of stock written off because it expired, was damaged or was spoiled by a cold-chain break.

Lower is better. Break it down by item, so the same products don't keep appearing on the write-off list.

How closely your system matches what is physically on the shelf.

Without accurate records, every other KPI is unreliable. Cycle counting (counting a few items every week rather than everything once a year) is the most practical way to keep this high.

OTIF is one of the strongest inputs to supplier evaluation and tender decisions. See our guide to the hospital procurement process.

The average number of days from purchase order to goods received, and how much it varies. Your reorder points and safety stock depend on this number, so measure the real figure rather than the one in the contract.

The days from an approved requisition to a purchase order being issued. A slow internal process can cause as many stock-outs as a slow supplier.

Off-contract buying usually means paying more and getting less service. A rising emergency-purchase count often shows up here first.

Compare it month to month and by department. For surgical services, cost per procedure is often more useful.

You don't need an expensive system to start. A spreadsheet is enough at first:

1. Pick 6–8 KPIs to start. Stock-out rate, fill rate, turnover, days on hand, expiry rate, inventory accuracy, OTIF and contract compliance cover most needs.
2. Define each one in writing: the formula, the data source, who owns it and how often it's measured.
3. Split by category. Report A/B/C and V/E/D items separately. A good hospital-wide average can hide problems in vital items.
4. Show the trend, not just the month. A 12-month line chart beats a single number.
5. Agree actions. Every KPI in the red needs an owner and a next step at the monthly supply chain meeting.

• Too many metrics. Thirty KPIs that nobody reviews are worse than eight that drive action.
• Averages only. Hospital-wide figures hide the vital items that matter most.
• Bad data in, bad KPIs out. Fix inventory accuracy before you trust turnover or days on hand.
• No link to decisions. KPIs should change reorder points, supplier choices and contracts. Otherwise they're just reporting.
