Interoperability Gains Haven't Delivered Usable Data, KLAS Finds

Overview

• Clinician agreement that EHRs deliver expected outside integration stayed between 39% and 49% from 2018 to 2024 despite broader exchange capabilities.
• Major vendors expanded connections through CommonWell, Carequality and QHINs, increasing data availability without resolving clinical usability gaps.
• KLAS reports no link between a vendor’s proprietary API count and customer satisfaction with third‑party integration, with Epic leading performance at 8.0 and athenahealth at 7.7.
• Clinicians still encounter duplicative entries, inconsistent formats and poor mapping, which limit the actionability of shared records.
• Payer‑provider exchange falters primarily due to trust concerns, while CMS rules and bulk FHIR requirements push technical sharing as KLAS case studies highlight partnership as the success factor.
