Abstract

The relationship between hospital specialisation and efficiency is crucial for managing hospital services. We discuss hospital specialisation as a specific instance of the more general concept of diversity and the conceptual opposite of variety. Unlike prior studies that focus on specialisation measures without a theoretical background, we employ the Blau Index, based on the concept of variety, enabling us to assess diversification's impact on efficiency.
