Overview:

A series of approximately 60 tables and reports has been developed for monitoring the quality of data submitted to the Uniform Data Set (UDS) of the National Alzheimers Coordinating Center (NACC). Twenty-nine Alzheimers Disease Centers (ADCs), funded by the National Institute on Aging (NIA), submit data collected on standardized forms from subjects enrolled in the Centers' individual research studies. Data are submitted through NACC's website and error-checked for clear-cut errors before being accepted into the UDS database. Additional quality assurance supervision is done by NACC staff to monitor less clear-cut data inconsistencies, using the Quality Assurance Reports. Base SAS and SAS IntrNet are used, including PROC REPORT, PROC TABULATE and ODS.
