The disadvantages of medical tourism range from dangers to the patient to a negative effect on society. For patients, there are important questions of safety and quality. Not all hospitals overseas are equipped like Bumrungrad, and even within a high-quality hospital, not all physicians have the same credentials. Language barriers and lack of available information can make it difficult for patients to ascertain the quality and standards of a foreign hospital or physician, and the criteria are not always clear. Whereas the Joint Commission International has sought to allay this concern, the rise of medical travel has brought new international accreditation agencies whose standards and judgment criteria are less well known. Potential conflicts of interest exist. The credentialing agency for the Dubai Healthcare City, the Center for Healthcare Planning and Quality, is located within the City itself, thus calling into question the regulation of water-source purity, sanitation, laboratory standards, infection control, food preparation, and the availability of a safe blood supply.18
