National study of the impact of patient information and involvement in decision-making on immediate breast reconstruction rates

Increasing socioeconomically disadvantaged patients' engagement in breast cancer surgery decision-making through a shared decision-making intervention (A231701CD): protocol for a cluster randomised clinical trial

INTRODUCTION

Socioeconomic disparities for breast cancer surgical care exist. Although the aetiology of the observed socioeconomic disparities is likely multifactorial, patient engagement during the surgical consult is critical. Shared decision-making may reduce health disparities by addressing barriers to patient engagement in decision-making that disproportionately impact socioeconomically disadvantaged patients. In this trial, we test the impact of a decision aid on increasing socioeconomically disadvantaged patients' engagement in breast cancer surgery decision-making.

METHODS AND ANALYSIS

This multisite randomised trial is conducted through 10 surgical clinics within the National Cancer Institute Community Oncology Research Program (NCORP). We plan a stepped-wedge design with clinics randomised to the time of transition from usual care to the decision aid arm. Study participants are female patients, aged ≥18 years, with newly diagnosed stage 0-III breast cancer who are planning breast surgery. Data collection includes a baseline surgeon survey, baseline patient survey, audio-recording of the surgeon-patient consultation, a follow-up patient survey and medical record data review. Interviews and focus groups are conducted with a subset of patients, surgeons and clinic stakeholders. The effectiveness of the decision aid at increasing patient engagement (primary outcome) is evaluated using generalised linear mixed-effects models. The extent to which the effect of the decision aid intervention on patient engagement is mediated through the mitigation of barriers is tested in joint linear structural equation models. Qualitative interviews explore how barriers impact engagement, especially for socioeconomically disadvantaged women.

ETHICS AND DISSEMINATION

This protocol has been approved by the National Cancer Institute Central Institutional Review Board, and Certificate of Confidentiality has been obtained. We plan to disseminate the findings through journal publications and national meetings, including the NCORP network. Our findings will advance the science of medical decision-making with the potential to reduce socioeconomic health disparities.

How are patient-related characteristics associated with shared decision-making about treatment? A scoping review of quantitative studies

OBJECTIVES

To identify what patient-related characteristics have been reported to be associated with the occurrence of shared decision-making (SDM) about treatment.

DESIGN

Scoping review.

ELIGIBILITY CRITERIA

Peer-reviewed articles in English or Dutch reporting on associations between patient-related characteristics and the occurrence of SDM for actual treatment decisions.

INFORMATION SOURCES

COCHRANE Library, Embase, MEDLINE, PsycInfo, PubMed and Web of Science were systematically searched for articles published until 25 March 2019.

RESULTS

The search yielded 5289 hits of which 53 were retained. Multiple categories of patient characteristics were identified: (1) sociodemographic characteristics (eg, gender), (2) general health and clinical characteristics (eg, symptom severity), (3) psychological characteristics and coping with illness (eg, self-efficacy) and (4) SDM style or preference. Many characteristics showed no association or unclear relationships with SDM occurrence. For example, for female gender positive, negative and, most frequently, non-significant associations were seen.

CONCLUSIONS

A large variety of patient-related characteristics have been studied, but for many the association with SDM occurrence remains unclear. The results will caution often-made assumptions about associations and provide an important step to target effective interventions to foster SDM with all patients.

Patient participation in treatment decision-making of prostate cancer: a qualitative study

PURPOSE

Despite increasing development in decision-making strategies for patients with prostate cancer, little is known about patients' individual experience and perception throughout the decision-making process. The objective of this study was to explore patients' experiences and perceptions towards treatment decision-making.

METHODS

We conducted a qualitative interview study with 30 patients diagnosed with prostate cancer. We transcribed interviews verbatim and inductively identified codes. Thematic analysis was used to develop and refine a codebook that aided in the identification of themes.

RESULTS

Three key themes and nine subthemes emerged, which were as follows: I. less involved in treatment decision-making, (i) passive decisional control, (ii) lack of medical knowledge, and (iii) domination by family members; II. the right to be informed of the disease condition and to choose treatment options, (i) sociocultural influences, (ii) patients believe that they should know the true facts of the disease, and (iii) patient autonomy during treatment; and III. future consideration and advance care planning, (i) fewer future concerns, (ii) advance care planning is poorly understood, and (iii) acceptance of advance care planning.

CONCLUSION

The study results show that patients with prostate cancer have a diversity of needs to cultivate their ability to make treatment decisions, and healthcare professionals should empower patients, as well as provide decision aids or decision support for patients.

Shared Decision-Making in Breast Reconstruction for Breast Cancer Patients: A Scoping Review

For most breast cancer (BC) patients who have undergone a mastectomy, the decision whether to proceed with breast reconstruction (BR) is complicated and requires deliberation. Shared decision-making (SDM) helps to address those needs and promote informed value-based decisions. However, little is known about the SDM status for BR in BC patients. This scoping review describes: 1) basic characteristics of studies on BR SDM in BC patients; 2) factors influencing BR SDM in BC patients; 3) experience and perception of BR SDM in BC patients; and 4) outcome measures reported. This review was performed in accordance with the Arksey and O'Malley methodology. A total of 5 English and 4 Chinese databases were searched, as well as different sources from grey literature. The data extraction form was developed by referring to the objectives and the Ottawa Decision Support Framework (ODSF). Data was analyzed using thematic analysis, framework analysis and descriptive statistics, with findings presented in the tables and diagrams. A total of 1481 records were retrieved and 42 of these included after screening. In 21 (21/42, 50%) of the studies, patient decision aids (PDAs) were utilized, and in 17 (17/42, 40.48%) of the studies, the factors influencing the implementation of SDM were explored. Of these 17 studies, the factors influencing the implementation of SDM were categorized into the following: the patient level (17/17, 100%), the healthcare level (2/17, 11.76%) and the organizational and system level (7/17, 41.18%). A total of 8 (19.05%) of the 42 studies focused on patients' experiences and perceptions of SDM, and all studies used qualitative research methods. Of these 8 studies, a total of 7 (7/8, 87.50%) focused on patients' experiences of SDM participation, and 4 (4/8, 50.00%) focused on patients' perceptions of SDM. A total of 24 studies (24/42, 57.14%) involved quantitative outcome measures, where 49 items were divided into three classifications according to the outcomes of ODSF: the quality of the decision (17/24, 70.83%), the quality of the decision-making process (20/24, 83.33%), and impact (13/24, 54.17%). Although researchers have paid less attention to other research points in the field of SDM, compared to the design and application of SDM interventional tools, the research team still presents some equally noteworthy points through scoping review. For instance, the various factors influencing BC patients' participation in SDM for BR (especially at the healthcare provider level and at the organizational system level), patients' experiences and perceptions. Systematic reviews (SRs) should be conducted to quantify the impact of these different factors on BR SDM. Implementation of scientific theories and methods can inform the exploration and integration of these factors.

A Randomized Controlled Trial to Assess the Use of a Virtual Decisional Aid to Improve Knowledge and Patient Satisfaction in Women Considering Breast Reconstruction Following Mastectomy

Background

The decisional process of navigating breast reconstruction surgery is very challenging for patients with a breast cancer diagnosis. This study aims to assess the impact of a virtual breast reconstruction decision aid program on the decision-making process of breast cancer patients considering breast reconstruction. 

Methods

A two-arm, randomized, controlled trial was conducted at the University of Pittsburgh. Patients were blindly assigned to one of two arms: Emmi Decide (Emmi Solutions LLC, Chicago, IL) program prior to traditional consultation (intervention) and traditional consultation alone (control). All patients completed a baseline pre- and post-intervention questionnaire to evaluate knowledge, patient satisfaction, and psychological status. Surgeons' satisfaction and consultation time were also recorded.

Results

A total of 26 patients participated in the study (n=13 in each arm). Patients in the intervention group reported a greater BREAST-Q reconstruction module score (control=47.9±8.2, intervention=56.8±4.2, p=0.0017), lower decisional conflict scale score (control=30.2±11.8, intervention=14.5±8.8, p=0.017), and improved patient knowledge (control=70.8±15.5%, intervention=83.1±13.8%, p=0.018). No difference was noted in consultation time (control=51.0±7.8 min, intervention=47.8±13.7 min, p=0.46) and psychological testing (control=49.7±16.0, intervention=44.6±15.2, p=0.26). However, surgeons reported greater satisfaction with their consultations with interventional group participants (control=3.4±0.7, intervention=4.8±0.4, p=0.000056).

Conclusions

The use of a virtual decisional aid program to assist the decision-making of breast reconstruction patients was shown to significantly benefit both patients and surgeons, by improving patient knowledge and satisfaction without placing an additional psychological burden on them. This supports the notion that this resource is a promising tool that can improve the difficult process of breast reconstruction in the vulnerable population of breast cancer patients. 

Patient-Reported Outcomes of Three Different Types of Breast Reconstruction with Correlation to the Clinical Data 5 Years Postoperatively

BACKGROUND

The aim of this study was to compare long-term clinical and patient-reported outcomes in terms of satisfaction and health-related quality of life (HRQoL) following postmastectomy breast reconstruction using BREAST-Q in patients undergoing implant-based reconstruction, abdominal-based autologous reconstruction, and combined reconstruction (with implant and LD flap or implant and TDAP flap).

METHODS

A cross-sectional study was conducted. Patients had undergone delayed postmastectomy breast reconstruction and completed the BREAST-Q reconstruction module. The results were related to the clinical data obtained from the clinic's patient record system. A 5-year examination was included. Mean scores and standard deviations were calculated. Kruskal-Wallis test, Chi-square goodness of fit test and Chi-square test were used for the statistical analysis.

RESULTS

Overall, 110 patients (n = 24 implant, n  = 38 autologous, n = 48 combination) were included. Patients with autologous reconstruction reported greater postoperative satisfaction with breasts (p < 0.001), satisfaction with outcome (p < 0.001), psychosocial well-being (p = 0.001), and sexual well-being (p = 0.051).

CONCLUSION

This study represents a comprehensive long-term examination of postmastectomy breast reconstruction. Autologous reconstruction patients had higher postoperative satisfaction and HRQoL than patients receiving other types of reconstruction despite having more intense oncological therapy and the highest mean number of follow-up surgical procedures.

Determinants influencing immediate breast reconstruction in an Australian tertiary public hospital

BACKGROUND

In Australia, the rate of immediate breast reconstruction (IBR) following breast cancer surgery is highly variable. This study aimed to identify the rate of IBR within an Australian public tertiary breast oncology referral centre and analyse the tumour and demographic factors that impact upon IBR uptake.

METHODS

A retrospective cohort study of 288 admissions of women requiring mastectomy between January 2012 and March 2015 was performed. Data collected included demographic data, tumour pathology, operative details and neoadjuvant therapy. Demographic data included a Socioeconomic Index for Area score, based on individual residential postcode, country of birth and need for an interpreter.

RESULTS

Our study demonstrated an IBR rate of 41.3% and included a wide variety of reconstructions. Factors that increased the IBR rate included younger age and negative lymph node status. Our patient population was ethnically and linguistically diverse, with over 50 different countries of birth represented and with 53 patients requiring interpreters in 19 different languages. Our analysis shows that the requirement for an interpreter is negatively correlated with having an IBR.

CONCLUSIONS

Our research demonstrates a high rate of IBR that includes a wide range of autologous and alloplastic reconstructions. Our study represents a unique opportunity to identify socioeconomic barriers that influence patient choice for reconstruction following mastectomy. This can lead to improved health care provision for our patients. This is particularly important in tertiary services with a strong multicultural and multi-linguistic population.

Breast reconstruction patterns from a Swedish nation-wide survey

OBJECTIVES

The overall aim of the Swedish Breast Reconstruction Outcome Study was to investigate national long-term outcomes after mastectomy with or without breast reconstruction. The current report evaluates breast reconstruction (BR) patterns in Sweden over time.

MATERIALS AND METHODS

This is a cross-sectional, registry-based study where all women operated with mastectomy 2000, 2005, 2010 were identified (N = 5853). Geographical differences in type of BR were investigated using heatmaps. Distribution of continuous variables were compared using the Mann-Whitney U test, categorical variables were compared using the chi-square test.

RESULTS

Mean age at survey was 69 years (SD=±11.4) and response rate was 50%, responders were on average six years younger than the non-responders and had a more favourable tumor stage (both p < 0.01). Of the 2904 responders, 31% (895/2904) had received a BR: implant-based in 58% (516/895)autologous in 31% (281/895). BR was immediate in 20% (176/895) and delayed in 80% (719/895) women. Women with BR were on average one year older, more often had a normal BMI, reported to be married or had a partner, had a higher educational level and a higher annual income when compared to those without BR (all p < 0.001). The independent factors of not receiving BR were older age and given radiotherapy.

CONCLUSIONS

To our knowledge, this is the first national long-term follow-up study on women undergoing mastectomy with and without BR. Around 30% of the survey responders have had a BR with a significant geographical variation highlighting the importance of information, availability and standardisation of indications for BR.

Influence of socioeconomic status on immediate breast reconstruction rate, patient information and involvement in surgical decision-making

Background

Immediate breast reconstruction (IBR) rates in breast cancer differ between healthcare regions in Sweden. This is not explained by regional differences in patient age distribution or tumour characteristics, but by differences in patient‐reported information and patient involvement in the decision‐making process. As socioeconomic status may play a significant role in surgical decision‐making, its potential associations with IBR rates were analysed.

Methods

Women who had undergone therapeutic mastectomy for primary breast cancer in Sweden in 2013 were included in the analysis. Tumour and treatment data were retrieved from the Swedish National Breast Cancer Register, and socioeconomic background data from the Central Bureau of Statistics Sweden. Postal questionnaires regarding information about reconstruction and perceived involvement in the preoperative decision‐making process had been sent out in a previous survey.

Results

In addition to regional differences, lower tumour and nodal category, independent factors increasing the likelihood of having IBR for the 3131 women in the study were living without a registered partner, having current employment and high income per household. Patient‐reported perceived preoperative information (odds ratio (OR) 12·73, 95 per cent c.i. 6·03 to 26·89) and the feeling of being involved in the decision‐making process (OR 2·56, 1·14 to 5·76) remained strong independent predictors of IBR despite adjustment for socioeconomic factors. Importantly, responders to the survey represented a relatively young and wealthy population with a lower tumour burden.

Conclusion

Several socioeconomic factors independently influence IBR rates; however, patient‐reported information and involvement in the surgical decision‐making process remain independent predictors for the likelihood of having IBR.

Socioeconomic status differs between breast cancer patients treated with mastectomy and breast conservation, and affects patient-reported preoperative information

PURPOSE

Breast cancer treatment is reported to be influenced by socioeconomic status (SES). Few reports, however, stem from national, equality-based health care systems. The aim of this study was to analyse associations between SES, rates of breast-conserving surgery (BCS), patient-reported preoperative information and perceived involvement in Sweden.

METHODS

All women operated for primary breast cancer in Sweden in 2013 were included. Tumour and treatment data as well as socioeconomic data were retrieved from national registers. Postal questionnaires regarding preoperative information about breast-conserving options and perceived involvement in the decision-making process had previously been sent to all women receiving mastectomy.

RESULTS

Of 7735 women, 4604 (59.5%) received BCS. In addition to regional differences, independent predictors of BCS were being in the middle or higher age groups, having small tumours without clinically involved nodes, being born in Europe outside Sweden, having a higher education than primary school and an intermediate or high income per household. Women with smaller, clinically node-negative tumours felt more often involved in the surgical decision and informed about breast-conserving options (both p < 0.001). In addition, women who perceived that BCS was discussed as an alternative to mastectomy were more often in a partnership (p < 0.001), not born in Sweden (p = 0.035) and had an employment (p = 0.031).

CONCLUSION

Socioeconomic factors are associated with surgical treatment even in a national health care system that is expected to offer all women the same standard of care. This should be taken into account and adapted to in preoperative counselling on surgical options in breast cancer.

Patterns of immediate breast reconstruction in New South Wales, Australia: a population-based study

Background

The rate of immediate breast reconstruction (IBR) following mastectomy for breast cancer in Australia is low and varies between regions. To date, no previous Australian studies have examined IBR rates between all hospitals within a particular jurisdiction, despite hospitals being an important known contributor to variation in IBR rates in other countries.

Methods

We used cross‐classified random‐effects logistic regression models to examine the inter‐hospital variation in IBR rates by using data on 7961 women who underwent therapeutic mastectomy procedures in New South Wales (NSW) between January 2012 and June 2015. We derived IBR rates by patient‐, residential neighbourhood‐ and hospital‐related factors and investigated the underlying drivers for the variation in IBR.

Results

We estimated the mean IBR rate across all hospitals performing mastectomy to be 17.1% (95% Bayesian credible interval (CrI) 12.1–23.1%) and observed wide inter‐hospital variation in IBR (variance 4.337, CrI 2.634–6.889). Older women, those born in Asian countries (odds ratio (OR) 0.5, CrI 0.4–0.6), residing in neighbourhoods with lower socioeconomic status (OR 0.7, CrI 0.5–0.8 for the most disadvantaged), and who underwent surgery in public hospitals (OR 0.4, CrI 0.1–1.0) were significantly less likely to have IBR. Women residing in non‐metropolitan areas and attending non‐metropolitan hospitals were significantly less likely to undergo IBR than their metropolitan counterparts attending metropolitan hospitals.

Conclusion

Wide inter‐hospital variation raises concerns about potential inequities in access to IBR services and unmet demand in certain areas of NSW. Explaining the underlying drivers for IBR variation is the first step in identifying policy solutions to redress the issue.

Variations in the utilization of immediate post-mastectomy breast reconstruction

BACKGROUND

For female breast cancer (BC) patients undergoing mastectomy, post-mastectomy breast reconstruction (PMBR) confers significant psychosocial benefits and improved cosmetic outcomes. The objective of this study is to explore whether the utilization of PMBR varies by race, marital status, and geographical location of the patient.

METHODS

Women ≥18 years old who underwent mastectomy for breast cancer diagnosed between 2000 and 2014 were eligible. Women with inflammatory BC, Stage IV BC diagnoses, and bilateral BC were excluded. Multivariable logistic regression, adjusting for patient and cancer characteristics, were used to assess the association between of race, marital status, and region on immediate PMBR utilization.

RESULTS

321,206 women were included and 24% underwent immediate PMBR (<4 months after mastectomy). Compared to white women, black and other non-white women (OR 0.67, 95% CI 0.65, 0.70 and OR 0.52, 95% CI 0.50, 0.53, respectively) were significantly less likely to receive PMBR. Additionally, women who were single (OR 0.72, 95% CI 0.70, 0.75) or no longer married (OR 0.84, 95% CI 0.82, 0.86) were significantly less likely to undergo breast reconstruction, compared to married women. Regional differences were also seen, with women in the Northeast (OR 2.11, 95% CI 2.05,2.17), Midwest (OR 1.53, 95% CI 1.48, 1.58) and South (OR 1.20, 95%CI 1.17, 1.23) all being more likely to undergo breast reconstruction compared to the West.

DISCUSSION

Significant variations exist in the utilization of post-mastectomy breast reconstruction across race, marital status or geographical location of the patient. Further research is needed to elucidate these differences and identify areas for intervention to increase awareness, and access to reconstruction for all breast cancer patients.

Association of sociodemographic and oncological features with decision on implant-based versus autologous immediate postmastectomy breast reconstruction in Chinese patients

Background and objectives

Immediate postmastectomy breast reconstruction (IPBR) has gained wide popularity in China. We sought to clarify the prevalence and predictors of implant‐based vs autologous IPBR among Chinese patients.

Methods

A retrospective cohort study was performed using a prospectively maintained database. Women who underwent IPBR during 2001‐2017 were included. The modality‐specific trends were deciphered by curve fitting analysis. The association of sociodemographic and oncological features with the decision for implant‐based vs autologous IPBR was investigated using multivariate logistic regression and structural equation modeling.

Results

Among 905 patients included in the study, 479 underwent implant‐based IPBR and 426 underwent autologous procedures. The implant/autologous ratio has increased exponentially over time. Multivariate analysis demonstrated that unmarried patients with BMI ≤ 24 kg/m², earlier clinical tumor stage, and preoperative pathological diagnosis of noninvasive lesion are more likely to choose implant‐based IPBR compared to autologous procedures. The indirect effects of age, mastectomy type, and neoadjuvant chemotherapy were further demonstrated by the structural equations.

Conclusions

The sociodemographic and oncological features are directly or indirectly associated with the decision on type of IPBR. The findings may facilitate both patients and physicians to make a high‐quality decision by holistic evaluation of the sociodemographic and oncological features.

Cost-effectiveness of the BRECONDA decision aid for women with breast cancer: Results from a randomized controlled trial

OBJECTIVE

To report on the cost-effectiveness of BRECONDA (Breast RECONstruction Decision Aid), a web-based decision aid to facilitate decisions regarding breast reconstruction surgery, with usual care for women with breast cancer.

METHODS

The economic evaluation was conducted alongside a randomized controlled trial. Women diagnosed with breast cancer or ductal carcinoma in situ and eligible for breast reconstruction following mastectomy were randomized to access BRECONDA for 6 months + usual care (n = 106) or usual care (n = 116) and were assessed at baseline preintervention, and then 1-month and 6-months post-randomization. Decisional conflict, satisfaction with information, decisional regret, and utilities were assessed by using maximum-likelihood linear mixed effects models. Costs included the fixed costs of BRECONDA, health care provider time, and health care resource use. Nonparametric bootstrapping was used to estimate incremental cost-effectiveness ratios.

RESULTS

BRECONDA resulted in significantly less decisional conflict and greater satisfaction with information over time. Quality-adjusted life years did not differ between participants who received the decision aid compared with usual care. The cost of BRECONDA was estimated to be small (AUD$10) relative to other health care interventions and resulted in decreased health care costs overall (AUD$764). Based on the point estimates, the decision aid was more effective and less costly (dominant) for all measures of effectiveness. It was estimated that the decision aid has an 87% probability of being cost-effective at $60 000 per quality-adjusted life year gained.

CONCLUSIONS

The BRECONDA web-based intervention designed to facilitate decisions regarding breast reconstruction surgery is likely to be cost-effective compared with usual care for women with breast cancer.

Regional variation in immediate breast reconstruction in Australia

Background

Breast reconstruction following mastectomy has proven benefits and is the standard of care in many high‐income countries. This audit documented regional variation in immediate breast reconstruction rates across Australia.

Methods

The Breast Surgeons of Australia and New Zealand (BreastSurgANZ) Quality Audit database and geospatial software were used to model the distribution of breast reconstructions performed on women having mastectomy in Australia in 2013. Geospatial mapping identified the distribution of these procedures in relation to the Greater Capital City Statistical Areas (GCCSAs) of the five largest states. Data were analysed using χ² tests of independence and an independent‐samples t test.

Results

Of 3786 patients having a mastectomy, 692 underwent breast reconstruction of which 679 (98·1 per cent) were immediate reconstructions. Rates of reconstruction differed significantly between jurisdictions (χ² = 164·90), and were significantly higher in GCCSAs (χ² = 144·60) and private hospitals (χ² = 50·72) (all P < 0·001). Immediate breast reconstruction was not reported for 43·8 per cent of hospitals where mastectomy was conducted by members of BreastSurgANZ, including 29·8 per cent of hospitals within GCCSAs. A wider age range of women appeared to have had immediate reconstructions at hospitals within GCCSAs, although the difference in mean age between regions was not significant. Immediate breast reconstruction was considerably less likely to be performed in women who lived in areas of lower to mid socioeconomic status.

Conclusion

Variations in the rate of immediate breast reconstruction may not be purely resource‐driven.

Quality of Patient Decisions About Breast Reconstruction After Mastectomy

Importance

Breast reconstruction has the potential to improve a person's body image and quality of life but has important risks. Variations in who undergoes breast reconstruction have led to questions about the quality of patient decisions.

Objective

To assess the quality of patient decisions about breast reconstruction.

Design, Setting, and Participants

A prospective, cross-sectional survey study was conducted from June 27, 2012, to February 28, 2014, at a single, academic, multidisciplinary oncology clinic among women planning to undergo mastectomy for stage I to III invasive ductal or lobular breast cancer, ductal carcinoma in situ, or prophylaxis.

Exposures

Mastectomy only and mastectomy with reconstruction.

Main Outcome and Measures

Knowledge, as ascertained using the Decision Quality Instrument; preference concordance, based on rating and ranking of key attributes; and decision quality, defined as having knowledge of 50% or more and preference concordance.

Results

During the 20-month period, 214 patients were eligible, 182 were approached, and 32 missed. We enrolled 145 patients (79.7% enrollment rate), and received surveys from 131 patients (72.0% participation rate). Five participants became ineligible. The final study population was 126 patients. Among the 126 women in the study (mean [SD] age, 53.2 [12.1] years), the mean (SD) knowledge score was 58.5% (16.2%) and did not differ by treatment group (mastectomy only, 55.2% [15.0%]; mastectomy with reconstruction, 60.5% [16.5%]). A total of 82 of 123 participants (66.7%) had a calculated treatment preference of mastectomy only; 39 of these women (47.6%) underwent mastectomy only. A total of 41 participants (32.5%) had a calculated treatment preference of mastectomy with reconstruction; 36 of these women (87.8%) underwent mastectomy with reconstruction. Overall, 52 of 120 participants (43.3%) made a high-quality decision. In multivariable analysis, white race/ethnicity (odds ratio [OR], 2.72; 95% CI, 1.00-7.38; P = .05), having private insurance (OR, 1.61; 95% CI, 1.35-1.93; P < .001), having a high school education or less (vs some college) (OR, 4.84; 95% CI, 1.22-19.21; P = .02), having a college degree (vs some college) (OR, 1.95; 95% CI, 1.53-2.49; P < .001), and not having a malignant neoplasm (eg, BRCA carriers) (OR, 3.13; 95% CI, 1.25-7.85; P = .01) were independently associated with making a high-quality decision.

Conclusions and Relevance

A minority of patients undergoing mastectomy in a single academic center made a high-quality decision about reconstruction. Shared decision making is needed to support decisions about breast reconstruction.
