A 60-bed Ontario long-term care home entered a norovirus outbreak on a Thursday evening and burned through three weeks of isolation gowns in four days. The home's clinical lead pulled the consumption logs afterwards and rebuilt every PPE par level from observed use rather than from a per-bed formula. The rebuild took two weeks and changed how the home orders gloves, gowns and masks.
This review walks through the failure, the arithmetic the home used to reset par levels, and the ordering changes that came out of it. If your home has ever discovered an empty gown shelf mid-outbreak, the sequence will look familiar.
What actually failed during the outbreak week?
The stock failure was not a single item. It was a compounding of three things: par levels set per bed rather than per contact, no outbreak multiplier, and a supplier lead time the home had assumed but never timed.
Under normal operations the 60-bed home consumed roughly 220 isolation gowns a week, mostly for resident care and laundry handling. During the outbreak week it consumed 1,180 gowns, plus 41,000 examination gloves and 2,600 procedure masks. The gown shelf emptied on day four.
Two structural issues made the shortage worse. First, the home held gowns in one central store, so a single aisle emptied while satellite carts stayed half full. Second, the reorder trigger was a fixed weekly count, not a days-of-cover calculation, so nobody saw the projected shortfall until it arrived.
How should par levels be calculated for a long-term care home?
Par levels should be built from resident contacts, not from bed count. A 60-bed home with a high proportion of residents needing assistance with toileting, feeding and repositioning will use more gloves and gowns per resident-day than a home whose residents are largely independent.
The method the home adopted has four inputs: baseline daily use per care stream, an outbreak multiplier, lead time in days, and a safety buffer. Baseline daily use came from existing logs. The outbreak multiplier was set at 3x for gowns and 2.2x for gloves, based on the home's own observed week. Lead time was measured, not assumed, by dating the last three purchase orders from approval to delivery. The buffer was set at five days of outbreak-level use.
| Item | Baseline weekly use | Outbreak week (observed) | Multiplier | Rebuilt par level |
|---|---|---|---|---|
| Isolation gowns, Level 2 | 220 | 1,180 | 3.0x | 1,600 held, 1,180 trigger |
| Examination gloves | 24,000 | 41,000 | 1.7x | 52,000 held, 41,000 trigger |
| Procedure masks | 1,500 | 2,600 | 1.7x | 3,400 held, 2,600 trigger |
| Face shields | 120 | 410 | 3.4x | 600 held, 410 trigger |
The trigger line matters more than the held line. Once on-hand falls to the trigger, the home raises a purchase order the same day rather than waiting for the next weekly count.
Which items run out first, and why?
In this home, gowns and face shields ran out before gloves. That pattern repeats across many outbreak reviews, and the reason is use concentration. Gloves are consumed across every care stream in small increments, so they draw down from a deep base. Gowns are consumed only in contact precautions and outbreak care, so their base stock is thinner and the multiplier applied to a small number still produces a small absolute buffer.
Order of draw-down in this case: gowns on day four, face shields on day five, masks on day six, gloves on day nine. The home now keeps a physically separate outbreak reserve for gowns and face shields, labelled and not drawn for routine care, so a single busy day cannot consume it.
What changed in the ordering routine afterwards?
The home moved to a two-bin system for gloves and masks, added a dated outbreak reserve for gowns, and started tracking days of cover instead of unit counts. It also moved to a standing monthly account with a wholesale supplier so that surge orders did not have to be priced from scratch under pressure.
Ordering for a clinic, lab or care home? Wholesale and multi-site ordering covers case pricing and account setup, and the B2B wholesale collection lists the lines stocked for institutional buyers.
For homes that also run in-house sterilization of reusable items, the monitoring side of the plan is separate: a 5-pack biological indicator trial is a low-commitment way to confirm the cycle monitoring routine before committing to a case quantity.

Frequently Asked Questions
How do you set PPE par levels for a 60-bed long-term care home?
Start from observed daily use by care stream, then apply an outbreak multiplier built from your own historical outbreak week. Add measured supplier lead time in days and a buffer of roughly five days at outbreak-level use. Review the par level quarterly, and after every outbreak.
Which PPE item runs out first in a norovirus outbreak?
Gowns and face shields usually go first. Their base stock is thinner than gloves because they are used only in contact precautions, so even a large multiplier produces a small absolute buffer.
What is a days-of-cover reorder trigger?
Instead of reordering at a fixed unit count, you reorder when remaining stock covers fewer than your measured lead time plus buffer. It exposes a projected shortfall before the shelf empties.
Does in-house sterilization monitoring change during an outbreak?
The monitoring routine does not change, but cycle volume does. More instrument loads per day means more indicators consumed, so the consumables plan should cover both PPE and sterilization monitoring lines.
