This study introduced a quantitative method to measure interoperability using real-world data and found that interoperability is generally low. Even among institutions using the same vendor, only about two-thirds of data types are accurately interpreted. True interoperability requires consistent data mapping to shared standards across institutions. Interoperability is influenced by both vendor product features and institutional implementation choices. However, focusing interoperability efforts on specific data elements could lead to misleading improvements.
