Standing Orders for Clinic Supplies: How to Set Reorder Points That Hold

Most clinics do not have an inventory problem. They have a reorder-point problem. The stockout happens because the trigger was set by feel — 'we usually order when the shelf looks low' — and feel cannot account for a delivery lead time that stretches to ten days in December.

The formula, stated plainly

Reorder point equals average daily usage multiplied by lead time, plus safety stock. Safety stock covers the days when usage runs above average or delivery runs late.

Worked example: a clinic uses 12 boxes of exam gloves a week, about 1.7 boxes a day. Delivery takes 7 days, and the practice wants 5 days of buffer. Reorder point = (1.7 × 7) + (1.7 × 5) = 12 + 8.5 ≈ 21 boxes. Order when the shelf drops to 21 boxes, not at zero.

Three numbers you need per item

• Average daily usage — take a month of records and divide. Use a recent month, not a pre-holiday one.
• Lead time — measure actual delivery dates for a quarter. Published lead times are frequently optimistic.
• Safety stock in days — how much risk your storage space and budget can absorb. Two to five days is typical for a clinic; longer for items with one supplier.

Where the calculation breaks

Seasonal drift

Glove and mask usage in a family practice rises through respiratory season. Set a second reorder point for October to March rather than averaging the year into a number that fits neither half.

Pack-versus-unit confusion

The formula works in whatever unit you stock. If the shelf is measured in boxes and the order is placed in cases, convert once and write the number on the shelf label. Mixed units are the single largest source of stocking errors.

Items that share a delivery

Consolidate: if gloves, table paper and pouches all arrive from the same supplier, use one order trigger based on the earliest item, and adjust with a small buffer. Fewer orders, less freight.

Making the standing order survive staff changes

A standing order is only durable when it is written down where the person doing the count will find it. Put the reorder point on the shelf label, keep a printed list in the supply room, and note who can authorize an off-cycle order. Clinics that do this stop losing stock to personality changes at the front desk.

Applying the formula to a real restock list

Two items show up on almost every clinic list. Exam table paper is a steady consumer: a 21-inch by 125-foot smooth perforated roll is easy to count by the roll, so the reorder point can be set in rolls. Gloves move faster and are the more common stockout, which makes 4 mil standard nitrile gloves in 100-count boxes a candidate for a higher safety stock.

Glove selection follows the same logic: match material and thickness to the task using published guidance such as CCOHS advice on protective gloves, then order to that specification rather than to habit.

Add sterilizer monitoring to the same sheet if the practice reprocesses instruments. The BI 5-pack trial is CA $12.99 with shipping included and behaves like any other consumable once you know your testing frequency.

Frequently Asked Questions

What is a reorder point?

The stock level at which you place the next order. It equals average daily usage multiplied by lead time, plus a safety buffer for days when usage or delivery runs off plan.

How much safety stock should a clinic hold?

Two to five days of usage is typical for consumables with reliable suppliers. Add more for single-source items or anything that would stop patient care if it ran out.

How do I measure lead time accurately?

Record actual delivery dates for a full quarter rather than trusting a published figure, then use the slower end of the range. Seasonal freight delays are common in December and January.

Should every item have its own reorder point?

Yes for anything high-usage, but group low-usage items that arrive from the same supplier into a single trigger. Fewer, well-sized orders beat a long list of small ones.
