Managed properly, rater training improves consistency and reduces variability in clinical trials, protecting endpoint accuracy. Managed poorly, it can undermine the entire study. A recent WCG webinar provided insights into this topic, exploring the challenges and the benefits for sites, sponsors, and CROs.
Reliability and Data Integrity
Rater training protects study endpoints, minimizing variability and enhancing rating reliability, which is essential for consistent clinical trial outcomes. Sponsors and CROs must ensure scoring consistency and endpoint quality across all clinical trial raters.
Standardized training tailored to the rater’s experience and expertise increases the likelihood that scales will be administered consistently, reducing the variables and biases that can creep into the process. Inaccurate or unreliable ratings can significantly increase the cost of clinical trials. Trials might need to be extended or even redone, leading to increased expenses for sponsors, frustration for sites. and disappointment for patients and participants.
Rater Qualification
Consistency is key— not just in training, but also in rater qualification and certification. A standardized approach ensures that each rater’s qualifications are assessed in the same manner. Assessment includes looking at factors such as their educational degree, field of study, relevant experience, and training.
The goal is to standardize rater qualification and training, allowing for data driven insights to inform study design and protect clinical endpoints.
To support this, WCG transitioned to a tiered qualification system: Expert, Experienced, and Developing raters. This system has the added benefit of increasing rater diversity, which fosters participant diversity. It also reduces churn while nurturing new raters. It allows for custom training pathways based on a rater’s experience level, ensuring robust training for developing raters and lessening the training burden on more experienced ones.
WCG’s InvestigatorSpace®, a comprehensive site and study team platform, recognizes and credits prior training, eliminating redundancy for raters working on multiple studies. If a rater has completed training on one study and joins another with the same requirements, InvestigatorSpace recognizes and automatically waives the requirement.
Consistency in Methodology
WCG’s iterative training approach focuses on minimizing common rater errors and constantly adapts based on observed trends. This protects endpoints and provides valuable insights into the training process’s effectiveness.
Studies can use an aggregate data set to really look at what is being done, how it’s being done, and ask: Is it meaningful? Does it add value? And where do we need to adjust?
Such insights are powerful. WCG can’t guarantee that your clinical trial will be a success, but we can help you understand why the data says what it says and course correct.
“Doesn’t Have to be Onerous”
Redundant training, complex workflows, and decentralized documentation complicate and slow the rater training process. All these challenges can be overcome with the right tools. The process doesn’t have to be onerous, difficult, or time consuming.
For example, InvestigatorSpace simplifies the training process, reduces redundancy, and provides easy access to crucial documents and training modules. Centralizing training-related data and documentation reduces errors, streamlines processes, and ensures uniformity across the board.
InvestigatorSpace provides:
- Mutual recognition of training: Cross-sponsor and cross-study exemptions mean less redundancy.
- User-friendly interface and easy workflow navigation: Single-sign-on access and automated workflowsmean all stakeholders can access their customized workflow.
- On-demand training methodologies: Raters can train on their own schedules and at their own pace.
- Mobile accessibility: A mobile app gives raters, investigators, and other site personnel access to protocol-specific documents, including the actual protocol.
- Automatic appeals process: A rater who fails to qualify on a scale can easily reapply and submit additional information.
- A centralized user profile: The user profile can be updated anytime and doesn’t need to be re-created for each study.
All of this is accessible on a single platform with a single login. The Study Home and Communication Resource Center centralizes all training-related data, providing a single unified space for all training criteria, assignments, retraining, certificate issuances, etc. It automates the distribution, collection, and maintenance of all training documentation.
