This white paper explores how post‑market surveillance is evolving from a reactive, complaint‑driven function into a proactive, data‑driven discipline focused on patient safety and product performance. It outlines global regulatory expectations under EU MDR, IVDR, and FDA frameworks, emphasizing the need for multi‑source data, integrated quality processes, and closed‑loop feedback into risk management and clinical evaluation. The paper also demonstrates how digitized, AI‑enabled QMS and RIM platforms can transform PMS into a strategic advantage for both compliance and commercial agility.
