Services typically sought by travelers include elective procedures as well as complex specialized surgeries such as joint replacement (knee/hip), cardiac surgery, dental surgery, and cosmetic surgeries. However, virtually every type of health care, including psychiatry, alternative treatments, convalescent care and even burial services are available.
Over 50 countries have identified medical tourism as a national industry.[3] However, accreditation and other measures of quality vary widely across the globe, and some destinations may become hazardous or even dangerous for medical tourists.
In the context of global health, "medical tourism" is a pejorative because during such trips health care providers often practice outside of their areas of expertise or hold different (i.e., lower) standards of care.[4][5] Greater numbers than ever before of student volunteers, health professions trainees, and researchers from resource-rich countries are working temporarily and anticipating future work in resource-starved areas.[5][6] This emphasizes the importance of understanding this other definition.
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.[7]. 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 cost $300,000 USD in America cost about $91,000 USD in Taiwan.[8] 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.[9] 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.[10]
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. In First World countries like the United States medical tourism has large growth prospects and potentially destabilizing implications. A forecast by Deloitte Consulting published in August 2008 projected that medical tourism originating in the US could jump by a factor of ten over the next decade. An estimated 750,000 Americans went abroad for health care in 2007, and the report estimated that a million and a half would seek health care outside the US in 2008. The growth in medical tourism has the potential to cost US health care providers billions of dollars in lost revenue.[11]
