Patient Preferences for Postmastectomy Breast Reconstruction

Abstract

ImportanceUp to 40% of women experience dissatisfaction after breast reconstruction due to unexpected outcomes that are poorly aligned with personal preferences. Identifying what attributes patients value when considering surgery could improve shared decision-making. Adaptive choice–based conjoint (ACBC) analysis can elicit individual-level treatment preferences.ObjectivesTo identify which attributes of breast reconstruction are most important to women considering surgery and to describe how these attributes differ by those who prefer flap vs implant reconstruction.Design, Setting, and ParticipantsThis web-based, cross-sectional study was conducted from March 1, 2022, to January 31, 2023, at Duke University and between June 1 and December 31, 2022, through the Love Research Army with ACBC analysis. Participants were 105 women at Duke University with a new diagnosis of or genetic predisposition to breast cancer who were considering mastectomy with reconstruction and 301 women with a history of breast cancer or a genetic predisposition as identified through the Love Research Army registry.Main Outcomes and MeasuresRelative importance scores, part-worth utility values, and maximum acceptable risks were estimated.ResultsOverall, 406 women (105 from Duke University [mean (SD) age, 46.3 (10.5) years] and 301 from the Love Research Army registry [mean (SD) age, 59.2 (11.9) years]) participated. The attribute considered most important was the risk of abdominal morbidity (mean [SD] relative importance [RI], 28% [11%]), followed by chance of major complications (RI, 25% [10%]), number of additional operations (RI, 23% [12%]), appearance of the breasts (RI, 13% [12%]), and recovery time (RI, 11% [7%]). Most participants (344 [85%]) preferred implant-based reconstruction; these participants cared most about abdominal morbidity (mean [SD] RI, 30% [11%]), followed by the risk of complications (mean [SD], RI, 26% [11%]) and additional operations (mean [SD] RI, 21% [12%]). In contrast, participants who preferred flap reconstruction cared most about additional operations (mean [SD] RI, 31% [15%]), appearance of the breasts (mean [SD] RI, 27% [16%]), and risk of complications (mean [SD] RI, 18% [6%]). Factors independently associated with choosing flap reconstruction included being married (odds ratio [OR], 2.30 [95% CI, 1.04-5.08]; P = .04) and higher educational level (college education; OR, 2.43 [95% CI, 1.01-5.86]; P = .048), while having an income level of greater than $75 000 was associated with a decreased likelihood of choosing the flap profile (OR, 0.45 [95% CI, 0.21-0.97]; P = .01). Respondents who preferred flap appearance were willing to accept a mean (SD) increase of 14.9% (2.2%) chance of abdominal morbidity (n = 113) or 6.4% (4.8%) chance of complications (n = 115).Conclusions and RelevanceThis study provides information on how women value different aspects of their care when making decisions for breast reconstruction. Future studies should assess how decision aids that elicit individual-level preferences can help tailor patient-physician discussions to focus preoperative counseling on factors that matter most to each patient and ultimately improve patient-centered care.

“…Patient-centered care is paramount in breast reconstruction, and surgeons should elicit patient goals and preferences and make recommendations in a shared decision-making approach in the context of their unique psychosocial situations. 20 , 21 …”

“…Patient-centered care is paramount in breast reconstruction, and surgeons should elicit patient goals and preferences and make recommendations in a shared decision-making approach in the context of their unique psychosocial situations. 20,21 Our study has several limitations, largely due to the nature of the PearlDiver database. PearlDiver, as an insurance claim database, providing data on the number of cases found with selected procedural codes and only general ancillary data such as age, gender, date, drug group, length of stay, and insurance plan type.…”

“…Once further evaluated in larger animal models and in clinical trials, this approach may help in treating patients with peripheral nerve injuries. 9 In this cross-sectional study, the authors used adaptive choice-based conjoint analysis to investigate treatment preferences among newly diagnosed breast cancer patients. Key factors shaping decisions included the risk of abdominal complications (greatest importance), overall complications, and the need for additional operations.…”
