Impact of preparation and execution of strategy to mitigate the platinum shortage within a network of community oncology practices.

e13572 Background: The US Oncology Network (USON) is made up of over 600 sites of care and treats 1,400,000 patients annually. Drug shortages have a massive impact on patient outcomes, particularly with limited source oncology medications. Proactive mitigation strategies by the national USON Pharmacy other cancers with alternatives had a decrease in admins (see table). Dose conservation guidance led to a decrease in average mg administered by 5.1% for cisplatin (72.2 vs. 68.5), and 6.2% for carboplatin (385.5 vs. 361.7). New admins of oxaliplatin increased by 11% (4,230 vs 4,714), primarily in GI malignancies. Conclusions: The rigors of stewardship with a phased approach allowed USON to sustain new patients while conserving cis/carbo for those with limited alternatives. Frequent communication about supply status and conservation guidance was critical for transition to alternative treatment strategies. This experience tested USON organizational readiness for future shortages. Table: see text
