Measuring the of healthcare service delivery of Nomenclature of Territorial Units for Statistics-1 (NUTS-1) territories in Turkey. Materials and Methods: Data Envelopment Analysis was conducted on the twelve Nomenclature of Territorial Units for Statistics-1 (NUTS-1) territories using three input variables and three output variables. Results: The results of the analysis demonstrate that Western Blacksea, Eastern Marmara, Southeastern Anatolia and Northeastern Anatolia are efficient and, Mediterranean, Eastern Blacksea, Istanbul, Central Anatolia and Mideastern Anatolia are inefficient in terms of all models. Besides, it is determined that Western Anatolia, Western Marmara and Aegean are efficient only in terms of Banker, Charnes, Cooper (BCC) models. Conclusion: It was determined as Western Blacksea, Eastern Marmara, Southeastern Anatolia and Northeastern Anatolia are efficient and, Mediterranean, Eastern Blacksea, Istanbul, Central Anatolia and Mideastern Anatolia are inefficient. It is suggested that confirm in the fuzzy environment these results adding new input and output variables and, using new generation Data Envelopment Analysis techniques such as Network and Two-Stage Data Envelopment Analysis.
