As part of HR/CRC, medical record abstraction is completed for each patient after completion of the interview. Information abstracted includes date of diagnosis, initial stage, and first course of treatment. In the HR/CSC sample, approximately 50% of patients had complete medical record abstraction. Prior to analysis in this study, HR/CRC personnel performed additional abstraction of cancer site and initial stage for older patients who had completed the PSQ-18 to further enrich data for this group.
