In February 2005, Banner Health undertook a comprehensive, IT-enabled initiative to implement evidence-based practices of care at its newest hospital, Banner Estrella Medical Center in Phoenix. The use of healthcare IT as part of the initiative helped the system save $2.6 million through improvements in nurse retention, decreased incidence of adverse drug events, reduced length of stay, decreased expenses, and more. Banner Health's experience provides persuasive evidence that healthcare IT investments can deliver clear financial value while enhancing quality of care. Rather than entrusting each of its hospitals with the task of identifying their own best practices, care sets, and work processes, Banner Health wanted to reach enterprisewide consensus on these matters. Although Banner Health recognized that IT-enabled care transformation delivers many benefits that are not easily quantified, the health system also wanted to study the quantifiable benefits of care transformation that could be translated into short-term economic benefits.
