To understand referral practices for rectal cancer surgical care and to secondarily determine differences in referral practices by two main hypothesized drivers of referral: the rurality of the community endoscopists' practice and their affiliation with a colorectal surgeon.Community gastroenterologists and general surgeons in Iowa completed a mailed questionnaire on practice demographics, volume, and referral practices for rectal cancer patients. Rurality was operationalized with RUCA codes.Twenty-two of 53 gastroenterologists (42%) and 120 of 188 general surgeons (64%) (total 144/241, 60%) in Iowa responded. Most performed colonoscopies, including 22 gastroenterologists (100%) and 96 general surgeons (80%). Regular referral of rectal cancer patients to colorectal surgeons was reported for 57% of urban physicians affiliated with a colorectal surgeon, 33% of urban physicians not affiliated with a colorectal surgeon, and 57% and 72% of physicians in large and small rural areas, respectively, who were not affiliated with a colorectal surgeon. High surgeon volume, high hospital volume, and colorectal surgeon specialty were important factors in the referral decisions for over half the physicians. 69% of diagnosing urban general surgeons reported performing rectal cancer surgery about half the time or more, while 85% of small rural and 60% of large rural diagnosing general surgeons reported never or rarely performing rectal cancer surgery.Diagnosing physicians have variable rectal cancer referral practices, including consistency in referred to surgeon and prioritization of volume and specialization. Prioritizing specialized or high-volume rectal cancer surgical care would require changing existing referring patterns.
