Background: In Denmark, a nationwide screening program for colorectal cancer was implemented in March 2014. Along with this, clinical database monitoring and research purposes established. Objective: The aim of this study to estimate the agreement validity diagnosis procedure codes Danish Colorectal Cancer Screening Database (DCCSD). Methods: All individuals positive immunochemical fecal occult blood test (iFOBT) result who were invited first 3 months since initiation identified. From these, sample 150 selected using stratified random sampling by age, gender region residence. Data from DCCSD compared data hospital records, which used as reference. Agreement, sensitivity, specificity negative predictive values estimated categories "clean colon", "colonoscopy performed", "overall completeness colonoscopy", "incomplete "polypectomy", "tumor tissue left behind", "number polyps", "lost "risk group polyps" "colorectal polyps/benign tumor". Results: Hospital records available 136 individuals. Agreement highest cancer" (97.1%) lowest (88.2%). Sensitivity varied between moderate high, 60.0% colonoscopy" 98.5% performed". Specificity 92.7% or above, except performed" where low; however, estimates imprecise. Conclusion: A high level indicates that reflects well. Further, high. Thus, may be valuable source future on screening. Keywords: screening, database,
