Past themes and future trends in medical tourism research: A co-word analysis

The results reveal six clusters of themes: a) issues regarding ethical implications, trust and accreditation; b) health, wellness, spa tourism and service quality; c) health-related issues, medical treatments and tourism; d) “sensitive” practices in MT; e) medical tourism destinations and marketing; and f) globalization, policies and the effect on international patients. This study is one of the first attempts to use a bibliometric approach and co-word analysis so as to offer powerful insight into the conceptual structure of MT research from academic literature and to visualize all the underlying and interconnected subfields. It also provides a guide to researchers by improving the understanding of the current state of the art and predicting the direction of future research.
