Inventory & Materials

Every hospital that has ever counted its stock knows the number on the screen and the number on the shelf disagree. The gap is created by issues that were never recorded against the patient who received them.

BatchExpiryDrawdownReorder

First question, first answer

The system you already run.

This is the question every materials manager asks before any other, so it is answered before anything else on this page.

The rule.Pensieve integrates with the inventory system a hospital already runs. Where there is none, the app is built in [Durin](/tools/durin), either by hospital staff with no code and no vendor ticket, or by a Pensieve forward-deployed engineer who builds it for the hospital and hands it over. Anything built that way sits on the same permissions and the same audit trail as the rest of the platform.
Either way, one drawdown.Whether the stock lives in your system or in one built in Durin, the fulfilment event is what draws it down. The count moves because something happened to a patient.

Impact and action

A count that drifts.

Stock is adjusted at the end of a physical count, and the adjustment is the only record that the drift ever happened.Consumption draws stock down at the moment of fulfilment, so the count moves with the work rather than against a memory of it.Forge
Batch and expiry are kept on a register beside the shelf, so the oldest stock is issued only when someone remembers to look.Batch and expiry are attributes of the item in the live view, and an expiry approaching raises an owned alert.FalconSentinel

Stock-outs the ward discovers.

A reorder level exists on paper and is checked weekly, so the first person to learn an item has run out is a nurse at a bedside.A reorder rule is written by the hospital and fires as an alert with an owner and an escalation chain, delivered on an audited channel.SentinelRaven
Nobody can say which items are both expensive and critical, so the store protects the wrong ones.Consumption value and clinical criticality are two readable views on the same data, so protection follows the evidence.Falcon

Stock that never became a charge.

An item is issued, used and never billed, so the loss appears as shrinkage rather than as the uncaptured charge it is.The issue that draws down the stock is the same event that posts the charge, so a used item and a billed item are one record.ForgeVault
A returned or wasted item is written off verbally.A return or a wastage is a recorded event with an author and a reason, on the same tamper-proof financial trail as every other transaction.Vault

The tools this store room runs on.

Each row is what the tool does with stock, and the example the person holding the keys would recognise.

Tools used in inventory and materials, what each does here, and an example.
Tool	What it does here	Example
Forge	Creates the fulfilment event that draws stock down.	A dose issued to a ward patient moves the count and posts the charge together.
Falcon	Reads batch, expiry, reorder position and consumption as one live view.	Items expiring inside sixty days, ranked by value on the shelf.
Sentinel	Fires the hospital’s own rules as owned, escalating alerts.	A critical item below reorder level escalates to the materials manager.
Vault	Carries stock movements into the ledger with a tamper-proof trail.	A wastage write-off carries an author, a timestamp and a reason.
Durin	Is the inventory app itself where the hospital has none.	Built by the materials team with no code, or by a forward-deployed engineer and handed over.
Westron	Connects an existing inventory system and keeps a trail of every exchange.	A nightly stock position arrives from the system the hospital already owns.
