CHAPTER I:

PROBLEM STATEMENT, GOALS, AND SCOPE OF THIS DOCUMENT

THE PROBLEM

In the late 1980s, increased efforts to pool data collected by different cancer registries drew attention to problems resulting from insufficient data standardization. This lack of standardization had a substantial cost and limited more widespread use of valuable data. Three groups especially felt the impact: state registries receiving data from hospital registries, the NAACCR Data Evaluation and Publication committee, and the Commission on Cancer's (CoC) National Cancer Data Base (NCDB).

The lack of standardization took many forms. Data items used by different registries or software systems varied in their definitions and codes, even when they had the same name and were intended to represent the same information. Blanks, dashes, and defined codes were all used to indicate “unknown” data. Other substantial discrepancies were less easy to detect and correct. Hospitals and software providers faced conflicting standards and requirements when they were both reporting to a central registry and maintaining a database consistent with CoC standards.

THE SOLUTION

Many NAACCR sponsoring organizations, including the National Cancer Institute (NCI), the Centers for Disease Control and Prevention (CDC), and CoC, recognized increasing standardization as an essential step in decreasing the costs associated with data collection, making more efficient use of increasingly limited human resources needed for data collection, management, and analysis, and obtaining more useful data that could be compared across registries and geographic areas.

Preparation of a statement of consensus on data standards for cancer registries was proposed by the NAACCR Data Exchange Committee (originally called the Data Exchange Standards Committee) spearheaded by NCDB, and the task fell to the newly formed Committee on a Unified Database which later morphed into NAACCR's Uniform Data Standards Committee, now called the Uniform Data Standards Work Group. Later, the CDC entered into an agreement with NAACCR, and one project under that agreement was the preparation of broader standards for population-based cancer registries. These efforts were complementary. Continued support from the NCI, the CoC, and the CDC has enabled continued development and maintenance of standards. The results of these efforts are the following standards documents published to date:

GOAL OF THIS DOCUMENT

The goal of this volume is to define NAACCR cancer registration data standards for use by central registries, hospital-based registries, and other groups in North America to abstract cancer diagnosed on or after January 1, 2022.

Objectives of the standardization effort, and this document, are to:

This document will be used by new and existing facility-based and central cancer registries to ensure that their program's standard definitions and codes are consistent with those used by regional and national databases. Other potential users include registry software providers and those using registry data, especially if they are combining data from multiple sources or exchanging data. National standard-setting groups, such as CoC, CDC, NAACCR, NCI and the Canadian Council of Cancer Registries (CCCR) will also benefit.

This Data Dictionary describes all current data items; those that are new or have been modified since the preceding Data Dictionary are listed in Appendix F. Highlighting in Chapter X also indicates changes.

The present volume uses the same structure and philosophy as NAACCR's data exchange standards. Where a standard exists for an item or type of data, the standard is incorporated by reference. Where a variety of standards are in use, alternate coding schemes accommodate them, but the different coding schemes are recorded separately, or another data field is used to indicate which coding standard was used.

SCOPE OF THIS DOCUMENT: WHAT STANDARDS ARE INCLUDED?

The present document is limited to standards regarding data, rather than procedures. More specifically, it focuses on a subset of possible data standards that NAACCR considers important to establish. These include:

Refer to Data Exchange Standard, XML Specification for Cancer Registry Records1or Data Standards & Data Dictionary, Volume II, Version 21, Chapter X for additional information on record layouts.

Where possible, the NAACCR item name is the same as that used by the standard setter. However, the following constraints are placed on the names:
