Gayle, In regards to # 7. I have lived and worked in 2 states with intermediate's, TX and NM. I appreciate the skills that intermediates bring to the table but a lot of folks wish they would do away with this level. NM doesn't utilize intermediates for much more than IV skills, TX is a physician extender state so most "I's" intubate and perform ACLS. If you note in or around 2013 the Intermediate-99 certs can take a "bridge course" to earn the Paramedic Patch. Perhaps this is one more step to eliminate Intermediate.
In my experience if you live in a rural community with hours long transport times to level II or level I facilty with no flight service available, intermediates are an economical solution. But if you have at least hospital based paramedics rendevousing (as we did in Tioga and Potter county when i lived there) they aren't needed. The other aspect that needs to be considered is what would their scope be? Paramedics will get upset if you encroach on "our" scope, and no one will want to be one if they are closer to basic scope of practice.
I haven't been in PA in 8 years (military) so please accept my criticism with a grain of salt. If there is an outcry for intermediates, i suggest we look at it like a new piece of equipment, if we "buy" it will it change how we treat our patients enough to soundly justify it beyond a reasonable doubt?
