Dispensing and the Last Check

Part of Trial Pharmacy (PHARM) Training: Dispensing and the Participant.

Why this matters

Dispensing is the point where a record becomes a real exposure. After this, corrections are deviations rather than edits.

The checks at handover

Right participant, identified by study number and a second identifier.

Right kit, matching the allocation, checked by number.

Right dose and route, against the reviewed prescription.

In date, and within any in-use window if prepared.

Correctly labeled, including expiry time for prepared doses.

Two people perform this where the protocol requires it, and the second check is independent.

Dispensing to a participant directly

For take-home product, add instructions they can follow at home.

How and when to take it. With or without food. What to do about a missed dose, which the protocol usually specifies and participants almost always ask. How to store it. To bring back everything, including empty packaging.

Ask them to repeat the storage and return instructions. Returns are the basis of adherence measurement, and participants throw packaging away unless told plainly not to.

Record at the time

Date, participant, kit number, quantity, who dispensed, and who checked.

The dispensing record is one side of the reconciliation. If it is written later from memory, the reconciliation is reconstructed rather than evidenced.

In practice

A participant arrives for a visit that is three days outside its window and the coordinator asks you to dispense anyway.

You check what the protocol says about out-of-window dispensing. If it permits it with a deviation, you dispense and the deviation is recorded. If it does not, you do not dispense and the investigator decides.

Pharmacy is not the place where the window rule gets quietly relaxed.

What this looks like when it goes wrong

A pharmacy dispenses to a participant whose randomization had not been completed in the system, on the coordinator's assurance that it would be done that afternoon.

The system later assigns a different kit. The participant has product that does not match their allocation, and neither record can be made true without falsifying the other.
