I missed it last week, but April 16th was National Healthcare Decisions Day 2008. Most people have an opinion on what type of medical treatment they would receive if they had the opportunity to visit with their healthcare provider. It certainly makes sense that one would want to establish ahead of time what type of medical treatment if they weren't capable of visiting. Unfortunately, a 2003 article reported that less than 50% of severely or terminally ill had an advanced directive in their medical record.
If you don't have an advanced directive already, take steps to have one signed. Then, after getting it signed, the next step is to have it included as part of your medical record.
