In medical device post-market activities, surveys are no longer simple feedback tools. When they support PMCF, PMS, or Real-World Evidence (RWE), they must meet clinical-grade standards.
That’s where many tools fall short.
To generate defensible evidence, manufacturers need Grade 4–level surveys — and with 1Survey+, that level is guaranteed by design, supported by blockchain-based data integrity. Here are the five essentials you need to know.
1 – Clinical-Grade Surveys Must Meet Grade 4 Standards
Grade 4 surveys are designed to support structured clinical evidence generation. They go beyond opinion gathering and ensure consistency, clarity, and methodological rigor suitable for regulatory and quality use.
Why 1Survey+ is different:
With 1Survey+, Grade 4–level survey capability is guaranteed. Surveys are created within a controlled, validated environment designed specifically for PMCF and RWE — not adapted from consumer-grade tools.
2 – Traceability Must Be Provable — Not Assumed
For clinical-grade evidence, traceability is non-negotiable. Regulators expect manufacturers to prove:
- Who submitted the data
- When it was collected
- That it has not been altered
Why blockchain matters:
1Survey+ uses blockchain technology to timestamp and anchor survey responses, creating an immutable record of when data was captured. This provides verifiable traceability — a foundational requirement for Grade 4 clinical surveys.
3 – Data Integrity Is What Makes Evidence Defensible
Volume of data means nothing if integrity cannot be demonstrated. Grade 4 surveys require evidence that data is protected from manipulation and remains consistent from collection through reporting.
How 1Survey+ guarantees integrity:
By leveraging blockchain-based immutability, 1Survey+ ensures that once survey data is captured, it cannot be modified without detection. This directly supports audit readiness and regulatory confidence in PMCF and RWE datasets.
4 – Multi-Stakeholder Input Strengthens Grade 4 Evidence
Clinical-grade evidence often requires perspectives from multiple stakeholders — clinicians, patients, and real-world users — all captured under the same methodological and compliance framework.
Why 1Survey+ excels here:
1Survey+ enables structured, Grade 4-level surveys across stakeholder groups while maintaining consistent blockchain-anchored records for every response, ensuring uniform traceability and integrity across datasets.
5 – Grade 4 Surveys Must Lead to Action — With Confidence
Clinical-grade surveys are not passive records. They inform PMCF evaluations, risk management updates, usability assessments, and product decisions — all of which require confidence in the underlying data.
How 1Survey+ supports decision-making:
With built-in dashboards and reporting, 1Survey+ turns blockchain-secured Grade 4 survey data into actionable insights — allowing teams to act quickly without questioning data reliability.
The Bottom Line
If your surveys support PMCF, PMS, or RWE, they are part of your clinical evidence framework — and they must meet Grade 4 standards.
With 1Survey+, Grade 4–level surveys are guaranteed, backed by blockchain-enabled traceability and data integrity that regulators and quality teams can trust.
