What I am finding is that a Patient Advocate has a focus on patient care. After the advent of the Birth Control pill (early 1960s), family size got smaller - meaning family internal support diminished. What I am finding is that more and more couples are by themselves and are the extent of the family support system. A church group can extend this, but the probability of support diminishes with lower church attendance.
I worked as a Logistician. (dictionary doesn't even recognize the spelling of this word).
As such (my working experience), I got whatever the client needed. I got sun tan oil (this needs a Material Safety Data Sheet or MSDS.) to aircraft parts even major end items (end items are items that when gotten are ready for end use or user uses). A tooth brush is a consumable due to low cost and - a generator or refrigerator is an "end item". A coordinator such as this needs to be "plugged in" to the various services to know what service or item can be delivered and at what cost. He or she also needs faith in the provider. Think of this person as a traffic light. Go Left, go right, stop, yield or go straight. The idea is to put the patient on the right track to obtain goods or services and shorten the time line from request to delivery and at minimal cost - and get them the needed support - giving them a heads up to bumps in the process ahead.
The other thing is that this person NEEDS to stay in touch and need to be available - knowledgeable about what is facing any particular patient - they physical size, abilities, an idea of their financial strength. Issues, conditions change - just like the weather. Another thing, is that we assume is that everyone has a computer and an e-mail- AND that it works - And that it works with whatever program is our favorite. All of these things are false. I have hated computers since I first started playing with them! I used to use a stylus to punch out the square holes in the old IBM cards. Not everyone has a computer or access or even an e-mail account.
In short, the "person" we are all seeking, does not yet exist in the support tree. Certainly some of those in the matrix are well versed, qualified and knowledgeable - but they aren't the basic "trigger" or the person who "makes things happen" on a full spectrum of support services.
Another "planning" thing I see too little of is a plan for disaster (big or small). When things go wrong ~ and they will ~ what is the backup plan? ALS (here in Texas) does have a contact person but it has been months since I have seen or heard from them. I guess I am as at much fault as they are.
Sorry for the rant.
