Evaluation of the Rectal Cancer Patient Decision Aid: A Before and After Study.

Background: In rectal cancer surgery, low anterior resection and abdominoperineal resection have equivocal impact on overall quality of life. A rectal cancer decision aid was developed to help patients weigh features of options and share their preference.

Objective: The aim of this study was to evaluate the effect of a patient decision aid for mid to low rectal cancer surgery on the patients' choice and decision-making process.
