Data Quality Assessments
Registry Certification
In 1997, NAACCR instituted a program that annually reviewed member registries for their ability to produce complete, accurate, and timely data. Each year, members of the Data Evaluation and Certification Committee (DECC) evaluate cancer incidence data for the most recent data year, based on pre-determined registry certification criteria established by the DECC. Following an evaluation by members of the Registry Certification Subcommittee (Subcommittee of the DECC), registry staff receive a report containing the results of registry certification evaluation for the most recent data year. In 2006, cancer incidence data from 73 population-based cancer registries were evaluated as part of the certification program and 7 Canadian and 56 U.S. registries were certified for their 2003 data. The percentage of the population that is reflected by certified registries for 1999-2003 data is approximately 82%.
NAACCR Call For Data
Starting in 2006, the NAACCR Call for Data began to utilize a secured area of the website for registries to complete their forms through an electronic submission process. A login is required to enter this area of the website. Vendors who are involved in the NAACCR Call for Data but cannot access the secured website can click here for access to all of the general submission information, definitions, documentation and data tools needed for the Call for Data.
Data Quality Reports From NAACCR Projects
Although it is best to assess and control data quality close to the course of data collection, it is also important that the data are evaluated as part of each study, project, or investigation. Sometimes the assessment of the data quality to address specific questions is the project. Reports are written that describe data quality issues uncovered during the course of a project and assess the impact of the data quality issue on the study and its results. These reports are compiled and made available to all potential users to improve their understanding of the value and limitation of cancer registry data for secondary analyses and for registry staff to use the information to continually improve their systems and processes that will result in more accurate data.
