A shelf life of 28 or 21 days is feasible without excessive increases to systemwide outdate, shortage, or emergency ordering rates. Large hospitals will see minimal impact; smaller hospitals will see larger increases and may be unable to find inventory policies that maintain both low outdate and shortage rates. Reducing the shelf life to 14 days, or lower, results in significant challenges for suppliers and hospitals of all sizes. All hospitals will see an impact on outdate and shortage rates; overall systemwide outdate rates (6% or more) will reach levels that would currently be considered unacceptably high.
