Implementation of a statewide quality assessment program for rectal cancer.

4 Background: The quality of surgical care for rectal cancer (RC) has been extensively studied in Europe; however, efforts in the United States are limited by the lack of detail about surgical care in available registries. We describe a unique quality assessment program for RC designed within the Michigan Surgical Quality Collaborative (MSQC), a collaborative quality improvement organization that includes community and academic medical centers. Methods: 10 MSQC hospitals contributed to this retrospective cohort study (2007-2012). Experienced nurse reviewers were trained to abstract cancer surgery-specific data from hospital medical records and local tumor registries. Five RC surgery-specific quality measures were designed based on literature review and current guidelines: adequate lymph node (LN) procurement (>=12); use of mesorectal excision; rate of margin positivity; use of neoadjuvant therapy for clinical stage II/III; and sphincter preservation rate for mid/upper RC. Results: 353 RC cases were studie...
