As a side note, I entirely agree that preventative care should be emphasized, as wellness education, immunization, and regular checkups HAVE been shown to decrease your chances for serious illnesses (as opposed to megavitamins, fad diets, and all the other garbage people seem very willing to spend their money on).
These ER frequenters aren't going to come in for checkups and things unless something's bothering them. Even if they make the appointment, they won't come. They won't have the courtesy to call ahead and cancel, either. They just won't show up.
