Community Health Nurses around the world: Meeting the Needs of the Homeless

I am a student nurse in California finishing up a semester about Community Health Nursing. My degree is in Public Health and I wanted to start a discussion to find out what kinds of things community health nurses are doing to meet the needs of the poor or homeless around the world?

I am especially interested in any input into the conversation from nurses in Canada, the United Kingdom, Norway, Australia, and other countries. Does the type of health system in place in your country seem to make a difference in the way vulnerable populations are cared for?

Any input from anyone with an opinion would be much appreciated.

Thank you,
