Re: Is this model just gaining traction, or has it been around for a while?
There have been companies doing this since the late 80's early 90's. Most were put in with a sponsor owned medical clinic. There have been some recent escalation in utilization. A large Indian tribe has put some in their casinos. Drugs and gambling? A major department store chain located in WI has put one in to service both local and national employees thru mail order. Companies that have the employees in house are starting to listen to alternatives and are more willing to think differently about these cost containment measures.
My longterm vision is to see companies that have their own pharmacies band together to own their own PBM. Local companies could co-op the cost of PBM ownership(actually very minor start-up) and share the benefit of true cost pass-thru transparency. Processing fees that are paid by the pharmacies would further cut costs to the sponsor-owned PBM.
