Cumulative Dose

Here is what it looks like: a patient receives three months of insulin in three days. Each individual dispense looks normal — reasonable quantity, valid prescriber, active coverage. But if the patient took everything as dispensed, it would be potentially life-threatening.

Multiple dispenses of the same molecule accumulate in a short period, exceeding safe limits established by the WHO. This can indicate medication diversion — where drugs are resold on the informal market — or systemic failures in dispensing control.

The 433 subscribers identified with this pattern represent both a financial risk and a patient safety risk. The dual nature of this signal — potential fraud and clinical risk — makes it one of the most critical patterns that slip through traditional processes.

At $14 median per transaction, cumulative dose may seem like a minor pattern. But 433 subscribers identified with dispenses exceeding safe limits represent a safety risk that goes beyond financial impact.

If a patient actually consumes all dispensed medication, the consequences can be severe or fatal. If they do not consume it, the medications are likely being diverted. In both scenarios, early detection is critical.
