Pulse Analysis

Over the past ten years St. Luke’s University Health Network has turned its Epic implementation into a flagship digital‑health project. The system grew from 18 to 42 Epic modules, a breadth that now covers everything from revenue cycle to advanced analytics. To support that expansion, the health network delivered more than 121,000 training sessions to its 41,000 clinicians and staff, ensuring consistent adoption across 16 hospitals. Early on, St. Luke’s also migrated its Epic environment from two on‑premise data centers to a public‑cloud platform, slashing disaster‑recovery times from hours to minutes and laying the groundwork for scalable analytics.

The cloud‑based architecture has unlocked unprecedented data exchange. Patient records shared externally rose from just over one million in 2016 to 13 million outgoing and more than 22 million incoming records today, while the Care Everywhere network helped clinicians close 3.3 million care gaps. Patient‑facing tools have kept pace: nearly one million MyChart users have completed over five million electronic check‑ins, viewed 37.5 million test results and submitted 1.5 million medication renewal requests. These figures illustrate how interoperability and consumer portals drive both operational efficiency and patient satisfaction.

Clinical decision support embedded in Epic is delivering measurable outcomes. The system’s sepsis model and real‑time Time Zero alerts lifted CMS bundle compliance from 82 % to 92 %, reducing septic shock incidence and mortality. Likewise, the Deterioration Index cut ICU transfers by 10 % and lifted survival‑to‑discharge rates to 36 %, placing St. Luke’s in the top decile for code events. Automated note summarization and in‑basket triage eliminated 19 million messages and reduced documentation time from seven minutes to just over seven seconds, translating into significant labor savings and faster care delivery.
