To follow on Mike's post, a lot of the issues with community based care is system based. ie a for profit system isint going to benefit from such novel ideas..again, a $$ thing.
Working as part of a government funded service, it's a different story and all about value for money and keeping those out of hospital who can be treated in the comunity and trying to save ambulance resources for 'real emergencies'. We are doing this both in a call diversion program (only in its infant stages) where callers can be directed to local services and a paramedic run extended care program to deal with minor wound care / burns, epistaxis, catheter problems, some home rx for migrane, gastro, etc. The major success is that everyone benefits. And yes, major baseline education differences.
And spending that extra few minutes preparing some food or having a cup of tea with a pt isn't just about doing a 'good deed' IMO, but is as much about being able to assess the daily living capacity of that person. Spending that extra 10 minutes chatting with someone and looking through the fridge can raise all sorts of red flags that might otherwise go unnoticed.
