💡 Accountant's Note
Blood is a highly perishable and specialized inventory item. Its usage is tracked patient-by-patient.
Practitioner & Systems Framework
💻 ERP Architecture
Blood bank inventory (packed red blood cells, platelets, fresh frozen plasma) is a unique perishable asset with a short shelf life (red cells: 42 days; platelets: 5 days). Track inventory by blood type, unit ID, collection date, and expiry date. Usage is recorded at the patient level — each unit transfused is linked to a specific patient encounter and generates both a supplies expense (cost to the hospital) and a charge to the patient's bill (revenue). Crossmatch and hold units must also be tracked — units held for a specific patient and not used must be returned to inventory promptly to prevent expiry wastage. Regular physical counts of the blood bank refrigerators must match the inventory system.
⚠️ Audit Flags
Auditors check that all blood units received from blood banks or collected in-house are recorded in inventory, and that usage ties to patient transfusion records and physician orders. Unexplained inventory discrepancies (units recorded as used without a matching patient transfusion record) are a serious patient safety and fraud concern. Blood bank accreditation (AABB or equivalent) requires specific inventory control procedures — auditors review accreditation status.
📄 Required Documentation
Blood unit receipt from supplier (unit ID, blood type, expiry date), patient transfusion record (physician order, nursing administration record, unit ID transfused), Blood Bank Inventory update, Medical Supplies Expense entry, patient charge for blood product (billing), expiry write-off records, crossmatch-and-hold tracking, and blood bank accreditation certificate.
