Here's my definition of a frequent flyer. Anyone who calls 911 on a regular basis...for what turns out to be no medical emergency. An example...the 82 yof who calls for "difficulty breathing" and she won't be quiet, who when asked, lives alone, vitals all better than the respective providers vitals. This same patient, when all tests are back from the hospital, is discharged with no significant findings.
It is this type of person who doesn't necessarily need medical care...as opposed to someone to talk to.
Now, there are other frequent flyers who have ETOH, drug problems and such, and are transported all the time. They either refuse rehab, says they will go to rehab, only to refuse and walk out in the morning, etc. etc.
These type, while I have no use for on a personal level, although one is quite funny once he's sober...but when drunk usually ends up assaulting staff. These are the more intensive frequent flyers who wouldn't be helped by going over to their house to see how they are and carry on a conversation. They need lots of other services, if they are willing to utilize them. They are NOT who we are talking about.
