Individual hospitals have been joining with other hospitals to form healthcare systems for decades.1,2 Often referred to as Integrated Delivery Networks (IDNs), they are growing larger and more integrated. This trend isn’t slowing down as mergers and acquisitions hit a record high in 2018. Why? As healthcare margins shrink and expenses rise, individual hospitals that comprise the system are looking for ways to impact the bottom line.2,3
Benefits come with economies of scale and centralization of redundant services, offering IDN’s the potential to be more effective at gaining operational efficiencies to save money on labor or by cost avoidance.4 For example, large healthcare systems can negotiate better drug purchasing contracts. And rather than performing the same task at each hospital, a group of hospitals working cooperatively can complete that task once (at scale), at a central location. Benefits of centralization seem to be well understood. A 2018 survey of 35 health-system respondents unanimously agreed cost savings opportunities for centralized pharmacy services include (and were not limited to) standardization of drug formularies, better volume discounts and better group purchasing organization (GPO) system-wide agreements.5 Naturally, with standardization also comes reduction in variability—a fundamental tenant of patient safety and high-reliability.6,7,8
