Glad to hear your son pulled through! Where I work we have a general hospital wide orientation followed but nursing specific orientation when we first get hired and then we are given additional instruction throughout our employment. One of the things that I found really helpful when I first started was hearing what it is like to be a parent in the ICU. We have something called patient family advocates, mostly parents of former patients or current long term patients, that are actually on staff and that tell their stories, answer questions and give suggestions to new nurses, doctors and other members of the health care team. They are also available to talk to families that are currently going through it because it is nice to talk to someone who has been in their shoes. I know the families and staff love it.
