本标准规定了制造商在体外诊断医疗器械性能评估研究中对研究计划、实施、评估和制定文件的职责和总体要求。
本标准适用于对体外诊断医疗器械的性能评估。本标准不适用于对某一特定体外诊断医疗器械或某一具体用途的评估方案。
Introduction
Analysis of the core content of the standard
As a programmatic document for the performance evaluation of in vitro diagnostic medical devices (IVD MD), this standard establishes the full process specification from research plan formulation to evaluation report generation. Its technical framework is coordinated with the international standard ISO 20916:2019, and at the same time, special requirements for self-test products are added in combination with China's regulatory practices.
Definition of key terms
| Terms | Definition | Application scenarios |
|---|---|---|
| Performance Evaluation Study | Systematic study to confirm that the IVD MD meets the performance claim under the intended conditions of use | Pre-market validation of new products |
| Evaluation Plan | Detailed plan including study objectives, sample size, timeline, etc. | Inter-laboratory comparison study |
| Non-professionals | Self-test product users without medical background | Evaluation of home testing devices |
Detailed explanation of implementation points
4.1 Establishment of responsibility system
Manufacturers need to establish a three-level responsibility system: the research leader coordinates resource allocation, the researcher performs on-site assessment, and the quality management team conducts the final compliance review. A typical case shows that Roche Diagnostics adopted a cross-departmental collaboration model in the evaluation of blood glucose meters, which shortened the evaluation cycle by 30%.
5.2 Evaluation plan design
The plan must include 7 core elements:
1) Proof of researcher qualifications
2) List of participating institutions
3) Phased time nodes
4) Basis for calculating the minimum sample size
5) Description of usage restrictions
6) Matrix of performance indicators to be verified
7) Standardized record template
Special requirements for self-test products
Taking the COVID-19 antigen self-test kit as an example, ≥200 non-professionals need to be recruited to participate in the evaluation. The test environment needs to simulate a home use scenario, and it is prohibited to provide operating instructions outside the instructions.
Technology Evolution Analysis
Compared with the 2003 version of YY/T 0287, the main progress of this standard is reflected in:
• Added Self-test Product Evaluation Specifications
• Clarified Software Confirmation Requirements
• Refined Sample Exclusion Criteria
• Strengthened Ethical Review Clauses
Compliance Implementation Suggestions
- Establish a dynamic evaluation mechanism and implement hierarchical management of design changes
- Use blockchain technology to ensure that research records cannot be tampered with
- Conduct GCP training for researchers regularly
- Refer to CLSI EP series standards to improve testing procedures
