Writing a Deviation Somebody Can Act On

Part of Clinical Laboratory (LAB) Training: Recognizing and Escalating Deviations.

About 2 minutes. Free, in your language, no account needed.

The reader is not in your laboratory

They cannot see the bench, the instrument or the rack. Everything they know comes from what you wrote.

Write for that reader.

What every deviation needs

What was required. Quote the manual, with the section and version.

What actually happened. Times, values, instruments, identifiers.

Which samples are affected, by identifier. All of them.

When and how it was discovered. Discovery by routine check reads differently from discovery by a monitor.

What you did. Immediate action, quarantine, notification.

What you do not know. Stated plainly.

Times and numbers, not adjectives

"Late" is not actionable. "Sixty-seven minutes against a sixty-minute limit" is.

"Warm" is not actionable. "Minus twelve degrees for nine hours against a minus seventy requirement" is.

Keep the cause separate from the event

Report the event as fact. Offer the cause as an assessment, marked as one.

"Probable cause: the freezer door was found ajar; no evidence establishes when it was opened." That is honest and useful.

Presenting a theory as a finding is how wrong corrective actions get implemented.

One deviation per report

Bundling three unrelated problems into one report means two get lost. Each needs its own assessment and its own corrective action.

The corrective action must address the cause

If the cause was an unclear manual, retraining does not fix it. If the cause was a training gap, a new form does not fix it.

A corrective action that does not match the cause is how the same deviation appears again next quarter.

Close it

A deviation without a documented outcome reads as unresolved forever.

Record the sponsor's assessment, the action taken, and the date it was completed.
