Ordering Commodities and Supplies Using Stock Cards

Introduction to Stock Cards and Inventory Control in Nursing

A stock card is a physical or digital ledger used in healthcare facilities to track the exact quantity of supplies, drugs, and commodities available in a specific unit or pharmacy. In Nigerian clinical settings, from primary health centres to tertiary teaching hospitals, proper inventory control prevents running out of life-saving materials like syringes, cotton wool, and anti-malarial drugs. Nurses often manage ward stores, making stock card maintenance a core clinical competency rather than a purely administrative chore. Every time an item enters or leaves the ward, the ledger must reflect the change immediately.

Anatomy of a Standard Stock Card: Key Terms and Fields

• Item Description: The specific name, strength, and dosage form of the commodity, such as Paracetamol 500mg tablets.
• Unit of Issue: How the item is counted, whether in tablets, ampoules, boxes, or rolls.
• Date: The exact day a transaction occurs.
• Receipts: Quantities of stock newly delivered into the ward store from the main pharmacy or central medical store.
• Issues: Quantities of stock taken out of the store for patient use or ward procedures.
• Balance: The running total of stock remaining after every receipt or issue.
• Signature: The initials or signature of the nurse or officer authorizing or receiving the transaction.

Calculating Stock Levels: Minimum, Maximum, and Reorder Levels

Effective inventory management relies on setting strict numerical thresholds to guide ordering decisions.

• Minimum Stock Level (Safety Stock): The absolute lowest threshold of supplies a ward must maintain. Dropping below this level risks a complete stockout before new orders arrive.
• Maximum Stock Level: The upper limit of stock a facility should hold. Storing more than this ties up capital, increases expiration risks, and creates clutter in small ward stores.
• Reorder Level: A predetermined point between maximum and minimum stock. When the balance drops to this exact number, it serves as an automatic trigger to submit a new requisition for supplies.

Routine Monitoring and Recording Stock Movements

Stock cards must be updated immediately upon every transaction, not at the end of the shift or week. Delaying entries leads to missing records, forgotten quantities, and inaccurate balances. Nurses conducting routine counts must physically verify items on the shelf against the numbers written on the card. Discrepancies between physical items and ledger balances require immediate investigation. Regular physical inventory audits protect against theft, spoilage, and misplacement of essential medical commodities.

Identifying When and How to Place an Order

Requisitioning supplies requires careful calculation of consumption rates and lead times. Lead time is the duration between placing an order and receiving the physical items in the ward. If lead time is long, the reorder level must be set higher to prevent a stockout while waiting. When the balance hits the reorder point, the nurse fills out a requisition form detailing exact quantities needed, referencing current stock card balances to justify the request.

Receiving, Inspecting, and Updating Stock Records

When ordered items arrive from the pharmacy or medical store, nurses must not sign the delivery note blindly. Every delivery requires physical inspection for quantity accuracy, damaged packaging, and correct batch numbers. Expiration dates must be checked immediately; short-dated stock should be flagged or rejected if it cannot be used in time. Once verified, the received quantities are entered into the receipts column of the stock card, and the new balance is calculated before storing the items properly.

Preventing Stockouts, Wastage, and Discrepancies

Poor inventory practices lead directly to compromised patient care and financial loss for health facilities. Stockouts halt emergency treatments, while overstocking leads to expired medicines filling shelves. Facilities apply the FEFO principle (First Expire, First Out), ensuring that items with the earliest expiration dates are used before newer stock. Regular auditing, secure storage locking, and strict adherence to stock card ledgers eliminate discrepancies and safeguard public health resources.
