An important resource for ensuring consistent data collection is maintaining a:

Maintaining a registry procedure manual is essential for ensuring consistent data collection within tumor registries. This manual serves as a comprehensive guide that outlines the protocols, definitions, and standards for data entry and management. By having clear procedures documented, it helps to minimize variability in how data is interpreted and recorded by different registrars, leading to improved accuracy and reliability of the data. This consistency is crucial when it comes to cancer surveillance, research, and treatment planning.

A suspense file, while useful for tracking incomplete cases or data that requires follow-up, does not directly contribute to consistency in data collection methods or standards. It is more of a tool for monitoring progress rather than a foundational resource for establishing uniform data procedures. Hence, the registry procedure manual stands out as the key resource for maintaining data integrity and consistency.
