I really do get the jist of this thread and think its spot on. Its comparable to expanding your practice with cosmetology, botox, etc when you haven't nailed down your basic practice.
Build a "perfect" EMR with CCHIT compliance (I guess that's unfortunately necessary now). Fix the little and big things. Worry about the PM system later. A PM system is a HUGE undertaking to build a really good one that scrubs the claims and works for all specialties. Plus, it will be tough to convert me to a new PM system as I just did that and it was VERY PAINFUL.
