Clinical Evaluation of a Lay-Language Radiology Glossary Integrated into an Electronic Health Record System.

ABSTRACT

Radiology reports typically contain complex, technical language that can pose a barrier to patients, especially to those with limited educational attainment or literacy skills. PORTER-the Patient-Oriented Radiology Reporter system-incorporates a lay-language glossary to help patients understand radiology report content. The system displays illustrations and definitions of radiology terms when viewing a report. A large U.S. health system integrated PORTER into the patient portal of its electronic health record (EHR) system and evaluated its use during a 7-month study period. Of 4,664 concepts defined in its glossary, 4,607 (98%) were readable at the 8th-grade level. Of 10,859 patients who completed a single-question survey, 6,947 (64%) found the system to be helpful or very helpful. A system that integrates illustrations and lay-language definitions of medical terms into a patient portal can help patients better understand the reports of their radiology examinations. Such a system has potential to improve communication for patients with limited health literacy.
