Understanding the State of the Art (SOTA) in Medical Device Clinical Evaluation under EU MDR

The introduction of the European Medical Device Regulation (MDR) has significantly transformed the landscape of medical device clinical evaluation within the European Union (EU). As medical technology continues to advance, ensuring the safety and efficacy of medical devices becomes paramount. The concept of State of the Art (SOTA) plays a pivotal role in this process, representing the highest level of development, knowledge, and innovation in a particular field at a given time. Understanding the SOTA is crucial for assessing the performance, safety, and effectiveness of medical devices, particularly during the clinical evaluation process.

What is State of the Art (SOTA)?

SOTA refers to the latest level of development, knowledge, and innovation attained in a specific field at a particular time. SOTA encompasses the most advanced technologies, methodologies, and scientific insights available for a given device or medical procedure.

Analysing the SOTA can be complex but immensely valuable, especially in early device development stages. It involves a structured literature search to understand current medical practices, treatment alternatives, and competitors. This information is pivotal for defining risk management, device claims, acceptance criteria, and clinical evaluation strategies.

SOTA often leads to adjustments in risk management documents post-clinical evaluation. However, conducting this analysis early can inform risk management decisions and clinical claims more effectively. It guides manufacturers in setting acceptable performance standards, selecting appropriate clinical endpoints, and devising data collection plans for both pre-market and post-market phases.
