Prospective Payment Systems (PPS) have been widely adopted over the past two decades as instruments for cost containment and efficiency improvement in health systems. However, much of the existing literature focuses on individual payment arrangements or single-country experiences, with limited attention to broader temporal, structural, and regional patterns reported across PPS-related reforms. This study examines patterns reported in the PPS-related literature published between 2000 and 2024, with particular emphasis on temporal trends, payment architecture, and regional variation in reform approaches.
