Brenda, we are a 150 bed hospital in southern Oregon. We get our products from ARC, three hours north. Our maximum ON stock is 6 units, ABP and ABN 2 units, OP (including 4 OP IRR) and AP 45 units, AN 12, including 4 AN IRR, BP 6 and BN 4. We get one PPH delivered three times a week. I don't know why, but we rarely waste any units of blood. We try to give sure transfusions the short dates, and all pre-ops long dates. Our shortest date OP is 4/10 and our longest date is 4/17. We send our PPH to a neighboring hospital (90 minutes south-they keep 5-8 on hand at all times) the day before they expire. We do try to have one PPH on hand all the time. I know you probably know all this, but this has worked well for us. If we urgently need a unit, we can have the highway patrol speed one up or down the highway to us.
