The IDN engaged in a collaborative project with its GPO called "30 in 2" to reduce its $700M annual supply spend by $30M within 2 years. Through centralizing processes, aligning physicians, analyzing spend, and optimizing contracts and vendor relationships, they achieved $45M in savings within 11 months, with $30M already implemented. Key was creating a customer-centric centralized supply chain through cross-organizational collaboration and communication. This reduced supply expenses as a percentage of net operating revenue to the lowest levels in the past decade.
