@Tigger, thanks. Yeah I understand that undoubtedly this won't hinder people from calling for silly reasons. TBH, I don't see that as much more of an issue when talking reductions in unnecessary taxes of an over-burdened system; this is kind of expected and shouldn't be a main focus in system abuse per se. That said, I don't have any first hand experience with MIH or CP programs, so I may be off.
While I can see mental health patients as being a large part of frequent flyer abuse, to an extent many times they're merely doing what it is they've always done. Redirecting them, seeing that they are properly medicating, and compliant etc. is definitely a positive step in reducing this, or any well-suited patient population from further over utilization of EMS as their ticket into an endless cycle of treat and release from various frustrated ED's without resolve.
Of the patients within your services jurisdiction, was your service doing home checks, and follow ups, and if so how challenging was it to see some of these types of patients through be it psych, poor compliant diabetics, cardiac patients or what have you through until they became compliant with either the medications, and/ or began properly seeking other outlets in healthcare (referrals)?
