The old understanding of service marketing focused on the differences between the product and the service within the framework of product-dominant logic rather than defining the service. Service-dominant logic does not compare product and service. It says that the basis of exchange is service and draws a framework. According to the service-dominant logic, actors in the ecosystem create value by integrating their resources and realizing service-for-service exchange in the light of the regulatory role of institutions. In this study, we tried to understand the extent to which professionals in health services adopt the service-dominant logic. Semi-structured interview technique, which is an in-depth interview technique, was used in the research. As a result of the study conducted with a total of 9 people, including 7 physicians and 2 non-physician hospital managers actively working in Istanbul, experts’ views on the actors, services, resources, value, and institutions in the healthcare ecosystem were obtained. Although the results are generally consistent with the literature, it is understood that patients, who are at the center of the service-dominant logic, are ignored by professionals and are considered as the service recipients rather than a part of the service.
