Hospital inventory management in Pakistan: beyond the pharmacy shelf

Hospital inventory conversations usually start and end at the pharmacy, because the pharmacy is the biggest store and the one with the clearest money attached. It is not the only place a hospital's working capital sits on a shelf.

Surgical consumables, theatre kit, lab reagents, radiology film and contrast, linen, engineering spares: each is a store with its own rules, and in most hospitals each is tracked by a different person in a different book.

The instinct is to buy a pharmacy system for the pharmacy and a store system for the stores. That produces a hospital that cannot say what it holds in total, and a finance office that reconciles by asking people.

The better structure is a single inventory model with multiple locations, where each location can enforce different rules. Pharmacy requires batch and expiry on every movement. Theatre needs issue at the level of a procedure, so that a case consumes a kit rather than forty individual lines. Engineering needs spares associated with a specific piece of equipment and its service history.

The point of one model is not uniformity. It is that a transfer between stores is a single recorded movement rather than a write-off in one book and a receipt in another.

Theatre consumables behave like pharmacy stock in every way that matters. They are expensive, they expire, they are consumed against a patient, and they are almost never recorded at that level.

Issue against the procedure rather than to the theatre as a room. That gives you consumption per case type, which is the only credible basis for costing a procedure, and it closes the same billing gap described in hospital revenue leakage.

Reorder points are consumption multiplied by lead time plus a buffer. In Pakistani hospitals the lead time term is the unreliable one. Imported lines move with shipping and currency, local distributors vary by season, and a supplier's quoted lead time is often an ambition.

That means the safety buffer is doing more work here than a textbook would suggest, and it should be sized from observed lead time variability rather than the quoted figure. Track delivery performance per supplier as a matter of course. It is the cheapest data you will ever collect and it directly sizes your working capital.

If purchasing happens in a spreadsheet and receipt happens in the inventory system, nobody can see what is on order. Stores then order again, because from the shelf it looks like nothing is coming.

Purchase requests, approvals, orders and receipts belong in the same system as stock, so that available stock, stock on order and pending approvals are one view. This is also where quotation-based procurement becomes manageable, because comparisons and approvals leave a record that an audit can follow.

Fixed assets are usually the last thing to enter an inventory system and the easiest to justify. A hospital needs to know what equipment it owns, where it is, when it was last serviced or calibrated, and which spares fit it.

That register also feeds the compliance documentation that inspections ask for, and it turns unplanned downtime into scheduled maintenance, which matters more in a hospital than the cost of the spares.

Start with pharmacy, because the money and the clinical risk are both largest there, and because the discipline you build transfers. The methods are covered in pharmacy inventory management and inventory control methods.

Add theatre second, since it is the next largest consumable spend and the one with the clearest billing consequence. Lab, radiology, engineering and linen can follow on the same model once the pattern is established.

BBB HMS treats all of these as one inventory model with per-store rules, so a transfer is a movement rather than a reconciliation, and the hospital can state what it holds in total.

The test of a hospital inventory system is not whether it produces a stock report. It is whether the finance office, the pharmacy and the theatre manager can all look at the same number and agree with it.
