Travel in Europe is pretty easy. Senza Gluten is all you need to say in Italy. They get it there as well as cross contamination.
Hospitals are notoriously horrible when it comes to GF. I don't understand why. At least the dietician told you they couldn't provide food. When my husband was in the hospital for a planned procedure they gave him a meal that contained gluten. Celiac was noted on his chart and they were also were notified in advance. Yet they still gave him a 'normal' meal.
