Take a look at this NGO a friend of mine is working at as a volunteer. Its main purpose is assisting poor families so that factors that cause a child's repeated visits to the hospital (lack of hygiene, bad nutrition etc.) are rooted out and eliminated. Families get NGO workers assigned to them, and they focus on fixing the problems that make children get sick.

In case they allow numeric flags but not text ones, I suggest "110596" (last time a Democrat won the White House).
