Dude, that's one of the worst-designed surveys I've ever run across.
First, who the hell listens to the MARKETING DEPARMENTS when considering elective medical treatment? You find out which physicians give good QUALITY of care. A hospital isn't a bloody spa or resort. If anything, marketing literature, to me, is of NEGATIVE importance -- the more some hospital tries to pimp itself with glossy leaflets espousing their adorable nursing staff, the more likely I am to assume they're not serious about their medical care. If I want to see chicks in "Nurse Naughty" costumes, I go to Pattaya, not Phyathai.
Secondly, regarding types of treatments that someone would "consider", your survey makes no effort to distinguish whether treatment is available at home or not. For example, in the U.S., the FDA approval process has a reputation for killing more people than it saves, because it delays time-critical treatments for cancer, AIDS, and other illnesses that are going to kill patients long before the approval process is completed. This is part of why Don Ho went to Thailand for cancer treatment a few years ago. On the other end of the spectrum, Britain and Canada both delay treatments for so long that patients are often forced to go elsewhere to get, e.g., joint replacement surgery in a timely fashion. You also don't seem to distinguish between people who are actually living abroad (and therefore more likely to go someplace else to get treated) and those who are living in a first-world country (and who might not need to go elsewhere for quality medical care).
Third, what's with the "yoga, spiritual, meditation, spa, stress relief, blah blah blah" junk? That has about as much to do with "medical tourism" as the availablility and cost of prostitutes.
Fourth, you don't specify whether "alternative treatments" means new-age garbage like coffee enemas, or if it means bleeding-edge cancer therapies that are being delayed by aforementioned FDA.
Fifth, you only list India, Thailand, and "other" as possible destinations. What, you haven't heard of Malaysia, Singapore, or Mexico?
Sixth, I'm not going to bother filling out income information or other fields that you require, so you're just not going to get my results. Try not requiring them and maybe you'll get more surveys filled out.
It's amazing what getting out of the care of the Scottish National Health Service can do for your life expectancy.
