Globalization and advancements in healthcare have birthed a novel form of tourism known as medical tourism. Over the past decade, MT has witnessed a significant upsurge, evolving into a burgeoning industry. The increasing popularity of medical tourism can be attributed to a confluence of factors, including the development of electronic communication systems, the improved ease of international transportation, the utilization of social media as a marketing tool, and the emergence of more cost-effective healthcare options. Healthcare system shortcomings in developed nations manifested as lengthy wait times, legal hurdles, and high costs, have driven the medical tourism movement towards developing countries. Conversely, advancements in technology and the dissemination of information have facilitated the promotion and marketing of medical tourism. Furthermore, medical tourism's appeal is augmented by its ability to offer a confluence of quality healthcare and vacation opportunities, attracting patients seeking a holistic experience. This study investigates the impact of destination image and social media interaction on medical tourists' intentions to visit Turkey. It explores their visit motivations, perceptions of quality and cost, and how these factors, along with their destination image formed through social media interactions, influence their decision to choose Turkey for medical care. Survey data for analysis was collected via social media from 1124 participants. These included citizens from the eight top source countries for medical tourists to Turkey (2018-2022): Iraq, Germany, UK, Azerbaijan, Bulgaria, France, and Georgia, along with Turkish dual citizens residing worldwide. Data analysis involved frequency analysis, evaluation of internal consistency for employed scales, and assessment of construct validity for sub-dimensions using confirmatory factor analysis. Mediation analyses explored the role of mediating variables, followed by linear regression and hypothesis testing via R software. Bootstrapping with 5000 repetitions examined indirect effects in mediation models. The research findings demonstrate the significant role of social media in shaping the formation of visit intentions in medical tourism. It has been determined that participants actively utilize social media to acquire information about medical tourism services in Turkey, and this interaction enhances their visit intentions. The impact of social media on creating destination image and shaping perceptions of the quality and cost of medical services is crucial. Additionally, it has been identified that perceptions of cost and quality influence potential tourists' visit intentions. Therefore, it is essential for medical tourism service providers to effectively market their destinations and enhance perceived quality by sharing accurate and up-to-date information via social media. The findings indicate that Turkey possesses a strong competitive advantage in the medical tourism market. Among these advantages are the perceived high quality of medical services in the country, low costs, modern healthcare facilities, well-trained physicians, and a wide range of medical services available. Consequently, medical tourism destinations need to focus on various strategies to strengthen destination image and optimize service quality. The effective use of social media, enhancement of cost and quality perceptions, positively influences potential tourists' visit intentions, creates a favourable medical destination image, and supports the tourism sector.
