Check out this site, benefitscheckup.org. While its definitely not as good as a live social worker, it's a good alternative resource. One can simply type in a locale, social and financial profile and the site will list the benefits (financial, medical, housing, utility, etc) available for those in tough financial straights and how to apply for said benefits. I just entered a hypothetical case, and the interview and results were quite comprehensive. A++ to the National Council on Aging for creating this resource!
Perhaps some of our ED patients will find this useful, particularly in these difficult economic times.
