The survey instrument
- How did you first hear about this centre?
- Which other providers did you seriously consider, and in which countries?
- What three questions mattered most before you decided?
- Which factor decided it: evidence, price, laboratory documentation, physician, language support, timing?
- Did a clinician at home advise for or against travelling?
- How many nights did you stay, and was that what you planned?
Publication and correction policy
Category counts publish with the denominator and the collection window. Where a category is too small to report without risking identification, it is grouped rather than dropped.
Corrections are published on this page with a dated note; earlier editions remain accessible rather than being silently rewritten.
