Description
Patricia Klarmann Ziegelmann and two co-authors present a 2025 method for counting cancer patients in Brazil's public health system. The system's claims database is a gold mine for real-world cancer data, but raw counts double-count people with more than one ID. A clean, open method was missing.
Their recipe counts each patient once, using a key built from sex, postal code, disease code, diagnosis date, and birth year to merge twin records. The steps ship as open R software that also pulls the data down. They proved the method on pancreatic cancer cases treated from 2008 to 2022, for adults in the public system.
