The 2024 Johns Hopkins Armstrong Institute Center for Diagnostic Excellence summit will focus on measuring diagnostic excellence. This event is a pivotal gathering for health care professionals and researchers eager to delve into the significance of timely, accurate and well-communicated diagnosis. 

Attendees will hear from their peers on: the importance of measuring diagnostic excellence; how to develop, test and implement measures that leverage available data and analytics; and implementation barriers and facilitators. Special attention will be given to ensuring equity and adopting a patient-centered lens for measurement, so that every patient receives the highest quality of diagnostic care. 

Elevate your understanding of equity and patient-centeredness in health care by exploring how these principles intertwine with diagnostic excellence, ensuring that every patient receives the highest quality of diagnostic care.
