Factors that have led to the increasing popularity of medical travel include the high cost of health care, long wait times for certain procedures, the ease and affordability of international travel, and improvements in both technology and standards of care in many countries. The avoidance of waiting times is the leading factor for medical tourism from the UK, whereas in the US, the main reason is cheaper prices abroad.
Many surgery procedures performed in medical tourism destinations cost a fraction of the price they do in the First World. For example a liver transplant that costs $300,000 USD in America costs about $91,000 USD in Taiwan.[5] A large draw to medical travel is convenience and speed. Countries that operate public health-care systems are often so taxed that it can take considerable time to get non-urgent medical care. Using Canada as an example, an estimated 782,936 Canadians spent time on medical waiting lists in 2005, waiting an average of 9.4 weeks.[6] Canada has set waiting-time benchmarks, e. g. 26 weeks for a hip replacement and 16 weeks for cataract surgery, for non-urgent medical procedures.
Medical tourists come from a variety of locations including Europe, the Middle East, Japan, the United States, and Canada. Factors that drive demand for medical services abroad in First World countries include: large populations, comparatively high wealth, the high expense of health care or lack of health care options locally, and increasingly high expectations of their populations with respect to health care.
