AbstractThis study was conducted to investigate the relationship between unplanned readmission and breast cancer operation cases, with the assumption that the rate of unplanned readmission within 30 days of surgery was solely due to postsurgical complications. We divided hospitals into three categories based on breast cancer operation cases: low-volume hospitals (< or =50 annual procedures), medium-volume hospitals (51-99 annual procedures) and high-volume hospitals (> or =100 annual procedures). The medical records of 1351 subjects in 24 hospitals were investigated. We found unplanned readmission rates were significantly higher in hospitals with a lower surgical volume. From these three groups, a sample consisting of 1351 patients was created and 17 unplanned readmission cases (1.2%) were reported. Of these 17 cases, 12 (70.59%) cases were from low-volume hospitals. The present results indicate that unplanned readmission within 30 days following discharge is an important adverse outcome in breast cancer surgery.
