Generally, we steer clear of individuals contracts for a couple of reasons, the primary one being that GPOs frown on it. We were Novation for years and have recently become a PACT member; both have been pretty emphatic against individual contracts.
Secondly, I think it's just one of the aspects of buying. You pay more to companies like Pfizer, etc., but make up the difference by staying on contract with everything else possible. And when a product comes out to compete with Pfizer, etc. you go for it!!
We are always willing to look at independant contracts. We also follow the Novation compliance when ever possible. I think my numbers last quarter were 89% compliant so you can take and utilize both options to ones advantage. We do what we have to to keep safe product available for our patients at the lowest possible cost. Sometimes an independant contracted product is the best price. I believe that is all part of the "buyer" job.
