    Post-Market Performance Follow-up(PMPF)

    In one line
    The IVDR counterpart of PMCF: ongoing collection and analysis of performance data after CE certification.
    Definition
    Annex XIII Part B of the IVDR requires manufacturers to plan and conduct PMPF as a continuous process that updates the performance evaluation. The PMPF plan specifies methods and procedures for collecting and evaluating clinical performance and safety data, and results are reported in a PMPF Evaluation Report that feeds the Performance Evaluation Report and the PSUR (Class C and D) or PMS Report (Class A and B).
    Why it matters
    PMPF is not optional. When a manufacturer concludes PMPF is not applicable, the rationale must be documented and justified. Registry participation and reflex-testing agreements with clinical laboratories are common PMPF data sources.
    Common pitfalls
    • •Confusing PMPF with general post-market surveillance activities, as PMPF has specific requirements for data collection and analysis under the IVDR.
    • •Failing to establish a PMPF plan or justify its absence for every IVD, which is a key IVDR requirement.
    • •Not sufficiently linking PMPF findings back to the performance evaluation report and clinical evidence, thus missing the iterative improvement aspect.
    • •Using only passive surveillance data for PMPF when active data collection is necessary to address specific performance questions.
    • •Underestimating the resources and expertise required to effectively conduct PMPF activities and analyze the resulting data.

    Why compare MedTech terms side by side?

    MedTech terminology is full of pairs that look interchangeable but carry very different regulatory, clinical, and commercial consequences. Picking the wrong framework, pathway, or standard early in a project can add months to a submission, invalidate clinical evidence, or trigger an audit finding. Side-by-side comparison is the fastest way to surface those differences before they become costly mistakes.

    Each comparison on this page pulls from the same vendor-neutral, sourced definitions used throughout the MedTech Terms glossary. You see the one-line summary, the formal definition, why it matters in practice, common pitfalls, and the primary sources (FDA guidance, EU MDR/IVDR articles, ISO/IEC standards, MDCG documents, IMDRF principles) that back each entry. That makes the comparison defensible in regulatory strategy memos, design reviews, and submission narratives.
