Quizplus · Accepted Answer

A disease registry is a secondary data source that aggregates extensive data about patients with a certain diagnosis. The purpose of a disease registry is typically to track and monitor the incidence and prevalence of a disease, as well as to evaluate and improve the quality and effectiveness of care for patients with that disease. A disease index is similar but is typically limited to information about patient diagnoses and procedures, rather than more extensive patient data. A master patient index and admissions register are not specifically focused on patients with a certain diagnosis.
