Given this background, experiences with medical decision making (see the we performed a qualitative study to better understand appendix). Participants were first asked to think how patients view their involvement in decisions back to a time when an important decision had to be made about treatment of an illness or medical condi-tion and then specifically prompted as necessary to discuss their involvement or lack of involvement inthe decision-making process.
