How to Establish Signal Management
Detect, evaluate, and act on safety signals across a product’s post-marketing life.
What a how-to is not
A how-to is SPEQ’s practitioner method, not a procedure. It does not replace your own SOP, it is not a validated approach, and the judgement calls in it belong to your quality unit.
Signal management is the pharmacovigilance process of detecting new safety information (signals), evaluating whether it reflects a real risk, and acting on it — up to changing the product information or taking regulatory action. A robust, documented signal-management process is a core post-marketing obligation and a frequent inspection focus.
- 1
Define signal detection
Define how signals will be detected and from which sources — the safety database, literature, regulator communications, clinical and post-marketing studies, and partner reports — with the method and cadence for each. Detection that relies solely on periodic statistical review of one database will miss the series of three unusual cases that a reviewer would have noticed, which is the failure mode that matters in practice.
- 2
Prioritise and validate signals
Prioritise detected signals so that urgent ones are handled urgently, then validate each: is there enough evidence that a new potentially causal association exists, or that a known one has materially changed, to justify further evaluation? Validation is a filter, not a verdict, and recording why something was not validated is as important as recording why it was.
- 3
Evaluate the signal
Evaluate validated signals against the full body of evidence — the cases with their quality and their confounding, the exposure data, the biological plausibility, the literature and any comparator experience. State what the evidence supports and what it does not, because the value of the evaluation is in its limits as much as its conclusion.

Decide and act
Decide and act within a time that is defensible against the signal’s seriousness. Outcomes range from continued routine monitoring through additional data collection to changes in product information or risk-minimisation measures. A signal evaluation that recommends only further monitoring should say what would change the answer, or the signal will be evaluated identically each period.
- 5
Document and track
Document each signal from detection to decision, and track it so that the record shows the elapsed time and the rationale at each stage. This is the trail an inspector reads, and the question is rarely whether a conclusion was right — it is whether the process was applied consistently and the decision was made in a reasonable time.
- !Signals detected but not tracked to a documented decision, so evaluation cannot be demonstrated.
- !Relying on a single detection method (e.g., only spontaneous reports) and missing signals from other sources.
- !Slow escalation, so a real risk persists longer than necessary.
- !No link from signal conclusions to actual product-information or risk-minimisation changes.
How to Establish Signal Management: frequently asked questions
Common questions on establish signal management.
What is a safety signal?
Information arising from one or multiple sources that suggests a new potentially causal association, or a new aspect of a known association, between a product and an event — usually judged likely enough to warrant verificatory action. Signal management detects, evaluates, and acts on such information.
How are signals detected?
Through review of spontaneous adverse-event reports, safety databases, published literature, and statistical/disproportionality methods, plus clinical-trial and other data. A robust process uses multiple sources rather than relying on one.
What happens when a signal is confirmed?
Action proportionate to the conclusion — from continued close monitoring, to updating the product information (label), to additional risk-minimisation measures or regulatory notification. The decision and its basis are documented in the signal-management records.
