Case Study: Community Health Network achieves enterprise-wide integration of five different EHRs and 70% operational efficiency improvement with Health Catalyst

Turning Data from Five Different EHR Vendors into Actionable Insights

Community Health Network (CHNw) faced fragmented clinical, financial, and operational data across four inpatient EHRs, two ambulatory EHRs and multiple transactional systems from five different vendors, which hindered enterprise reporting, data standardization, and accurate patient matching. To address patient-safety and value-based care challenges, CHNw selected Health Catalyst’s Late-Binding™ Enterprise Data Warehouse (EDW) and established executive-backed data governance to unify definitions and workflows.

Health Catalyst implemented the EDW, data standardization processes, and a patient-to-patient matching solution, integrating key sources within 12 months. The platform consolidated more than 55,000 data elements and 18 billion rows, enabled matching for over 1.1 million patients, and drove a roughly 70% improvement in operational efficiency—data architects now spend an estimated 15% of their time on interfaces versus 40–50% previously—while accelerating reporting and quality-improvement efforts.
