Detect. Assess. Intervene. Evaluate.

WCG Analgesic Solutions’ Quantitative Data Surveillance System (QDSS) is the only risk-based monitoring system to combine statistical process control and other analytical techniques with real-time human expertise. This approach provides insights and actionable recommendations, allowing Sponsors to address data-quality issues and protect study outcomes.

In any trial, especially those with subjective measures, the Sponsor or CRO needs a way to identify–and mitigate–data-quality risks. Now they can.

By implementing QDSS, sponsors increase the likelihood of a positive outcome while meeting scientific and regulatory expectations for data quality.


1 Million statistically aberrant signals detected
50k+ clinically relevant signals evaluated and prioritized
1k+ sites monitored worldwide
QDSS empowers you to see and respond to study issues in-flight

Throughout the course of the trial, QDSS monitors selected metrics to identify statistically significant and clinically relevant aberrant signals in near real-time. This allows the project team to look under the hood while the trial is running (and blinded) and identify and address threats in a timely manner.

QDSS systematically and consistently recommends strategies and actions to correct data issues and mitigate risk. The QDSS Rules Engine standardizes and documents decisions made by the clinical and data teams. This process ensures uniform practice and protection of data quality and allows study teams to address issues as they arise.

QDSS provides retrospective analysis of completed trials

From protocol design to study conduct, your past trials contain important lessons. Retrospective analysis unlocks these lessons, all but eliminating the guesswork from future trials.

We can perform retrospective analyses of your past trials to identify patterns and gain insights into what went right–and what went wrong. You can learn from your stunning successes and your most painful failures.

These insights provide valuable guidance on the conduct of current and future studies, allowing you to optimize current and future studies.

Detect aberrancies early

Capture statistically significant signals of aberrant performance at the patient, site and study levels for assessment, intervention and follow-up.

Turn insights into interventions

Identify threats to the outcome of the study before they do lasting damage, and ensure interventions are deployed to address data-quality threats as they are detected.
