The medical tourism / service field is currently troubled by agent problems and no platform is available to solve them. There are currently four major agent problems. The question of brokerage expenses: An agent exists to ensure reliability between the consumer and provider of health care. But it soon led to complicated processes and inevitably led to higher brokerage expenses. Central agency incompetence and corruption: Medical tourism consumers and medical institutions must comply because the agent has control of information and currency transac- tions. In the end, if an agent is incompetent or corrupt, it hurts all participants. Target of hacking: Since all information and books are concentrated in one place, it is easy to become target of hacking. Trust issue: Medical institutions and consumers lack the space to build trust, which in turn leads to a lack of trust with each other.
