AbstractBackground: Decision Aids (DA) are developed with the intent to support people in making specific and deliberate choices by improving information transfer about different outcomes. Previous research has shown that DAs can increase patient knowledge regarding treatment options, reduce decisional conflict, and increase patient satisfaction with the decision-making process. However, no DAs have been developed to help older breast cancer patients decide whether or not to undergo adjuvant RT. We developed and tested a DA for older women with stage I,ER/PR positive breast cancer considering adjuvant treatment post-lumpectomy and we examined its impact on treatment decision-making process.Methods and Materials: A DA was developed and evaluated in three steps following the Ottawa Decision Aid Framework: 1) Needs assessment (N=16); 2) Pilot I, to examine the DA's acceptability (N=12); and 3) Pilot II, a pre-test post-test (N=38) with older women with ER/PR responsive breast cancer post-lumpectomy who were receiving adjuvant RT. Measures included questionnaires to assess patient's satisfaction with the DA, patients’ self-reported decisional conflict (DC), level of distress, treatment-related knowledge, and choice predispositionResults: The DA is a booklet that details each adjuvant treatment option's benefits, risks and side-effects tailored to their clinical profile; includes a value clarification exercise; and steps to guide them towards their own treatment decision. All women felt the DA was helpful and informative. Compared with baseline scores, patients had a statistically significant (p < .05) reduction in DC (adjusted mean difference [AMD], −7.18; 95% confidence interval [CI], −13.50 to 12.59); increased clarity of the treatment benefits and risks (AMD, −10.86, CI, −20.33 to 21.49; and improved general treatment knowledge (AMD, 8.99, CI, 2.88 to 10.28) after using the DA. General trends were also reported in patient's choice predisposition scores suggesting potential differences in treatment decision after DA use. Discussion: This study provides evidence that this DA may be a helpful educational tool for this group of women. The quality of care for older breast cancer patients may be enhanced by using a tailored DA to help the patient be informed of their treatment options and to prepare for decision-making.Citation Information: Cancer Res 2011;71(24 Suppl):Abstract nr P5-15-03.
