The Implementation of DRGs in Greece: A comparative analysis with Germany and recommendations for effective system adoption

Introduction: DRGs are used to categorize hospital cases for reimbursement based on diagnosis, procedures, and patient characteristics. Germany, a pioneer in adopting DRGs in 2003, has established a highly efficient system that serves as a model for other countries. In comparison, Greece began applying DRGs in 2012 and continues to face difficulties such as incomplete data recording, lack of specialized personnel, and limited infrastructure. Aim: The aim of this study is to analyze and compare the implementation of DRGs between Greece and Germany, and to propose solutions for a more effective application in the Greek Healthcare System. Method: This study uses a literature review and analysis of the DRG implementation in both Greece and Germany, focusing on technological infrastructure, the categorization process, and continuous education. Results: Key differences between the two countries include advanced technological capabilities in Germany versus manual processes in Greece, a comprehensive classification system in Germany versus a less developed one in Greece, and a strong focus on continuous training for healthcare professionals in Germany compared to Greece's lack of emphasis in this area. To improve the DRG system in Greece, the article recommends upgrading technological infrastructure, implementing targeted staff training programs, refining DRG categories to better align with healthcare needs, and establishing evaluation mechanisms for ongoing assessment. Conclusion: Despite the challenges, the application of DRGs in Greece offers significant benefits. With appropriate investments in technology and staff training, the efficiency of the healthcare system can be improved, leading to better reimbursement outcomes.
