ObjectiveTo evaluate a web-based breast reconstruction decision aid, BREASTChoice.Summary And Background DataAlthough postmastectomy breast reconstruction can restore quality of life and body image, its morbidity remains substantial. Many patients lack adequate knowledge to make informed choices. Decisions are often discordant with patients' preferences.MethodsAdult women with stages 0-III breast cancer considering postmastectomy breast reconstruction with no previous reconstruction were randomized to BREASTChoice or enhanced usual care (EUC).ResultsThree hundred seventy-six patients were screened; 120 of 172 (69.8%) eligible patients enrolled. Mean age = 50.7 years (range 25-77). Most were Non-Hispanic White (86.3%) and had a college degree (64.3%). Controlling for health literacy and provider seen, BREASTChoice users had higher knowledge than those in EUC (84.6% vs. 58.2% questions correct; P < 0.001). Those using BREASTChoice were more likely to know that reconstruction typically requires more than 1 surgery, delayed reconstruction lowers one's risk, and implants may need replacement over time (all ps < 0.002). BREASTChoice compared to EUC participants also felt more confident understanding reconstruction information (P = 0.009). There were no differences between groups in decisional conflict, decision process quality, shared decision-making, quality of life, or preferences (all ps > 0.05). There were no differences in consultation length between BREASTChoice and EUC groups (mean = 29.7 vs. 30.0 minutes; P > 0.05). BREASTChoice had high usability (mean score = 6.3/7). Participants completed BREASTChoice in about 27 minutes.ConclusionsBREASTChoice can improve breast reconstruction decision quality by improving patients' knowledge and providing them with personalized risk estimates. More research is needed to facilitate point-of-care decision support and examine BREASTChoice's impact on patients' decisions over time.
