Building google sublinks (site sections)

[BrutusUnix]

When I use google example IBM I get:

IBM - United States
The IBM corporate home page, entry point to information about IBM products and services.

Show stock quote for IBM Downloads
Jobs at IBM Investor Relations
Support & downloads Employee directory
Products Contact
Select a country
More results from ibm.com »

I have the site: http://www.Sprymed.com

When my site comes up I want the same thing but with:

Hospital Discussion Topics Hospital Ranks
HCAHPS Scores Medical Discussion Groups

Is this an xml file on the index page? If so what's the name of it
Thanks

Google gathers these links purely by their formula. Also, those links will only come up on a branded search, ex: if you google "sprymed". I'd recommend making sure you have a clean sitemap, "About Us", "Contact Us", "Support", and other common web pages that are clearly defined.
