Which software function is unique to hospital registries?

• A. Submitting data to the Centers for Disease Control and Prevention
• B. Generating data for clinicians
• C. Conducting active patient follow-up
• D. Submitting data to the American College of Surgeons' National Cancer Database

Answer: (C)

Hospital registries are built to track patients over time and capture how they fare after initial treatment. The key function that sets them apart is active follow-up: regularly reaching out to patients or their clinicians to update vital status, disease progression, additional therapies, and any recurrence or new cancers. This ongoing data collection is essential for calculating long-term survival, understanding treatment effectiveness, and driving quality improvements within the hospital.

Other tasks described—submitting data to public health agencies like the CDC, generating data for clinicians, or contributing data to a national database such as the NCDB—are important but not unique to hospital registries. These reporting and data-sharing activities can be done by various registries and programs, whereas actively pursuing up-to-date patient status over time is a distinctive capability that hospital-based registries emphasize to monitor outcomes longitudinally.
