The German healthcare system is undergoing a structural change. Today, medical practices must meet a wide range of demands. Advances in medicine need to be taken into account, the economic situation is becoming more challenging, and the influence of laws and regulations is increasing. Additionally, competition among medical practices, patient satisfaction, and the demonstration of quality provided are playing an increasingly important role. On January 1, 2004, the Health Modernization Act came into effect. The legislator mandates the introduction and further development of a quality management system as well as participation in quality assurance measures. Since then, every medical practice is legally required to engage with the topic of quality management. This book demonstrates both theoretically and practically how a quality management system can be successfully implemented with minimal effort.
