This is another form of Birkat Hagomel. One occasion when one should say Birkat Hagomel is after recovering from a serious illness esp. if it involved a hospital stay.
In the NY City area, and I assume some other areas throughout the U.S., many of the bikur cholim ("hospitality" rooms) are run and maintained by Hassidic groups. In NY area, Satmar runs a majority of them. Women cook and bake fresh food daily and they package and deliver food to numerous hospitals in the NY area. On numerous occasions I had to visit a relative on Friday, and I had no food at home for my family or myself for Shabbat. I was thrilled that there was a fridge with food that I could take home.
So, these are not just "good" Hassidm - they are phenomenal Hassidm. I honestly don't know how they manage to do this each day.
So, whether you are ill or not, the bracha refers to Hassidm such as these people who go far above and beyond to care about the ill as well as their families, and request nothing in return but a bracha and a voluntary monetary donation.
