Long-term health outcomes of a decision aid: Data from a randomized trial of adjuvant! in women with localized breast cancer
Decision Support Techniques
Outcome Assessment (Health Care)
Expected benefit from treatment is a key variable in understanding patient behavior. A small number of women refuse adjuvant treatment associated with large increases in predicted survival, even when they are explicitly informed about the degree of benefit they would forgo. Investigation of the effects of decision aids on cancer survival is unlikely to be fruitful due to power considerations.
