Abstract
Introduction
Health outcomes research has gained considerable traction over the past decade as the medical community attempts to move beyond traditional outcome measures such as morbidity and mortality. Since its inception in 2009, the BREAST-Q has provided meaningful and reliable information regarding health related – quality of life (HR-QOL) and patient satisfaction for use in both clinical practice and research. Now five years from its initial publication, we review how researchers have utilized the BREAST-Q and how it has enhanced our understanding and practice of plastic and reconstructive breast surgery.
Methods
An electronic literature review was performed to identify publications that used the BREAST-Q to assess patient outcomes. Studies developing and/or validating the BREAST-Q or an alternate patient reported outcome measure (PROM), review papers, conference abstracts, discussions, comments and/or responses to previously published papers, studies that modified a version of BREAST-Q, and studies not published in English were excluded.
Results
Our literature review yielded 214 unique articles, 49 of which met our inclusion criteria. Important trends and highlights were further examined.
Discussion
The BREAST-Q has provided important insights in breast surgery highlighted by literature concerning autologous reconstruction, implant type, fat grafting, and patient education. The BREAST-Q has increased the use of PROMs in breast surgery and provided numerous important insights in its brief existence. The increased interest in PROMs as well as the under utilized potential of the BREAST-Q should permit its continued use and ability to foster new innovations and improve quality of care.
Introduction
Health outcomes research in surgery has gained considerable traction over the past decade as the surgical community attempts to curb soaring health care costs and move past traditional outcome measures such as morbidity and mortality.1 As a component of this change, patient-reported outcome measures (PROMs), wherein the patient’s perception of his or her outcomes is quantified, have become increasingly important.2 In plastic surgery, patient-centered outcomes data is of particular importance as the majority of operative interventions aim to improve appearance, function and/or quality of life. Thus, while photographic analysis remains indispensable, the new focus on patient perceptions offers potentially valuable insights into the effectiveness of surgical interventions.
The BREAST-Q, a validated PROM now translated into thirty languages, quantifies the impact of cosmetic and reconstructive breast surgery (i.e., augmentation, reduction/mastopexy, mastectomy, reconstruction, and breast conserving-therapy), pre- and post-operatively, on health-related quality of life (HR-QOL; including physical, psychosocial, and sexual well-being) and patient satisfaction (including satisfaction with breasts, outcome, and care) (see Figure 1). Investigators and clinicians can choose to use only those scales that are pertinent to their research question. The questionnaire items in each scale are arranged in a clinically relevant hierarchy (e.g., Satisfaction with Breasts scale ranges from “How satisfied are you with how you look in a mirror clothed?” to “How satisfied are you with how you look in the mirror unclothed?”). While each scale produces an independent score from 0–100, there is no overall BREAST-Q score. Scores are transformed via the Q-Score program (https://webcore.mskcc.org/breastq/) or designated tables.2,3
In this review, we examine the use of the BREAST-Q in the surgical research literature, and in particular how use of the BREAST-Q has enhanced the understanding and the practice of plastic and reconstructive breast surgery.
Methods
An electronic literature review was performed to identify publications that used the BREAST-Q as an outcome measure. Two search engines, PubMed and EMBASE, were queried with the terms “BREAST-Q” and “BREASTQ” from inception to January 2015. Two authors (WC and LM) separately reviewed all of the titles and abstracts of all articles identified in the search to exclude non-relevant articles. Any differences in opinion were resolved by a third author (AP). Included articles described the use of the BREAST-Q in a primary research study that assessed patient outcomes in a breast surgery population. Studies developing and/or validating the BREAST-Q or an alternate PROM, review papers, conference abstracts, thesis, commentaries, letters to the editor, studies that used a modified a version of BREAST-Q, and studies not published in English were excluded. A citation review of included articles was performed to identify any additional articles.
For publications that met the study inclusion criteria, we extracted the following information: country of origin, study aim, study design, sample size, BREAST-Q module utilized, and key findings. Study design was classified as prospective cohort or cross-sectional. Prospective cohort studies were defined as studies in which patients completed the BREAST-Q at multiple time points. Cross sectional studies were defined as those in which patients completed the BREAST-Q at a single time point. BREAST-Q data collection was classified as pre-operative, post-operative, or both.
Results
Our literature review yielded 214 unique articles. After implementing the exclusion criteria, 49 manuscripts from peer-reviewed journals met our inclusion criteria and were included in the analysis (Figure 2).
Since its inception in 2009, the number of publications incorporating the BREAST-Q has increased each year (Figure 3). From the 49 publications, a total of 22,457 patients completed at least one subdomain of the BREAST-Q. Of these participants, 20,390 patients completed one or more scales from the breast reconstruction module. The breast reconstruction module was utilized in 39 references; the augmentation module was reported in 7 references; the reduction module in four; and the mastectomy module in three.
The cross sectional study design was the most prevalent, being used in 71% of publications (n=35). The BREAST-Q was administered in a prospective study design in 29% of studies (n = 14). Two studies distributed the questionnaire only pre-operatively, 29 only post-operatively, and 18 both pre- and postoperatively. Within the augmentation module, the majority of studies included both pre- and post-operative assessments (71%), while among the reconstruction module, post-operative assessment only was more common (72%).
In all but one publication, the Satisfaction with Breasts scale was used. Within the HR-QOL domain, the sexual, physical, and psychosocial domains were used with almost equal frequency in 41, 40, and 43 studies, respectively (Figure 4).
Table 1 provides a summary of findings from the 49 publications identified by this review. The comparative effectiveness of different approaches to breast reconstruction was a popular topic; authors investigated outcomes of silicone versus saline implants, and also of autologous versus implant reconstruction. The BREAST-Q was used to highlight emerging techniques in plastic surgery with fat grafting figuring prominently. It was also used in one large UK study to compare the performance of different hospital providers. Lastly, while much of the literature focused on surgical outcomes, a number of studies also used the BREAST-Q to evaluate the patient experience.

Discussion
Since its inception in 2009, the BREAST-Q has been used to study breast surgery providing meaningful and reliable information regarding HR-QOL and patient satisfaction when used in clinical practice, in surgical research and quality improvement initiatives. This condition-specific PROM has been rapidly accepted by academic and private clinicians alike. Use of the BREAST-Q will continue to expand as HR-QOL and patient satisfaction becomes increasingly important as a metric for evaluating patient care from clinical, policy, and research perspectives. Below we consider five key areas of surgical practice, and elaborate upon the findings of this review to more fully describe where the BREAST-Q has and can be further used to better understand evidence-based, patient-centered surgical practice.
Why choose autologous reconstruction?
Reconstructive surgeons and their patients must choose between autologous and implant-based reconstruction following mastectomy. While traditional outcomes, such as rates of failure and re-operation have been well studied, the BREAST-Q has been used to provide a better understanding the impact of this decision on patients.4–6 There are now a number of studies that suggest the outcomes are better for patients receiving autologous reconstruction in comparison to implants.7–11 While the studies did not make a distinction between microsurgical techniques, the authors report that patients had higher levels of satisfaction, increased HR-QOL, and less chest and upper body morbidity with autologous reconstruction compared to implants.
The superior outcomes in the autologous reconstruction patients is additionally supported by previous studies not utilizing the BREAST-Q, which demonstrated superior aesthetic results when comparing transverse rectus abdominis myocutaneous (TRAM) reconstruction with implant-based reconstruction. 6,12–17 Additionally, Matros et al conducted a cost-effectiveness analysis, and reported that the more expensive procedure (autologous reconstruction) is worthwhile when cost and quality of life were factored together.17 The BREAST-Q provides researchers with the ability to quantify and compare patient perspectives, which is essential to demonstrate the value of potentially more time intensive or costly reconstructive options, such as free-tissue flap based reconstruction.
Which is better – saline or silicone?
With the moratorium on silicone implants now lifted,18 patients are presented with an option of silicone or saline implants. While some surgeons recommend silicone implants for their natural feeling and appearance, studies using the BREAST-Q provide evidence that can be used to help guide patients in their decision making process.4,19 In augmentation patients, Gryskiewicz et al. demonstrated that patients who received silicone implants were more satisfied with their overall outcome than patients who received saline. 20 In breast reconstruction patients, multiple studies have demonstrated similar findings with higher overall satisfaction, psychological well-being, sexual well-being, physical function, and satisfaction with their surgeon in patients receiving silicone implants in comparison to saline. 20–23 The BREAST-Q has been instrumental in helping to demonstrate greater patient satisfaction with silicone implants compared to saline, providing essential information to help future patients make educated decisions about reconstructive options.
Why perform fat grafting?
The use of fat grafting in breast surgery is becoming increasingly popular. 24 Multiple authors demonstrated high rates of satisfaction with breasts using the BREAST-Q in fat grafting for both reconstruction and augmentation. 24,25 Salgarello et al. demonstrated that fat grafting followed by autologous or implant-based reconstruction produced high satisfaction with breasts among patients who had previously undergone breast radiation, while Spear and Pittman found high patient satisfaction with breasts following fat grafting when used for breast augmentation.24,25 In a case report, Howes et al demonstrated the potential for autologous fat grafting as an option for whole breast reconstruction.24 While multiple questions remain regarding fat grafting’s safety, efficacy, and post-operative breast cancer screening, the BREAST-Q should help assess patient satisfaction with the procedure.
Why focus on patient education?
An important component of overall patient satisfaction is the patient experience of care, which can be measured using the BREAST-Q scales, satisfaction with information; surgeon; medical team; and office staff. These scales were utilized in only 49% of studies. In order to deliver patient-centered care and improve patient outcomes, surgeons and their teams should make the patient feel at ease and provide adequate pre-operative information. Ho et al. demonstrated that when a patient is satisfied with the information provided to her and also with the plastic surgeon, she is more likely to be satisfied with her surgical outcome. 26 These findings are supported by expectancy theory, which hypothesizes that pre-operative expectations play an important role in the patient’s assessment of outcomes and strongly predicts satisfaction and HR-QOL. 27–29
While most institutions track patient satisfaction, current methods using questionnaires, like those employed by Press-Ganey, which are not condition-specific, are often used for promotional advertising. The BREAST-Q, developed based on patient interview data, with its inclusion of different features of the patient experience, imparts providers with a surgery specific metric to improve their weaknesses, while reinforcing their strengths.
Is the BREAST-Q feasible in large-scale studies?
The National Health Service (NHS) audit on mastectomy and breast reconstruction included data from more than 8,000 women seen at 270 different hospitals throughout the United Kingdom.9 Postal surveys utilizing the BREAST-Q were returned at a rate of 81% during the study. This audit provided clinicians with important HR-QOL and patient satisfaction data, while highlighting the importance of adequate pre-operative information to patients. 9
In another study, Atisha et al conducted a study utilizing the Love/AVON Army of Women program.10 The cross sectional study surveyed women who had previously undergone surgery for breast cancer to compare different reconstructive procedures and how satisfaction changes over time for specific patient populations. 7,619 patients completed the BREAST-Q, electronically with an 82% response rate. Women who underwent autologous tissue reconstruction reported the highest breast satisfaction, while women who underwent a mastectomy without reconstruction reported the lowest.
Finally, the BREAST-Q is featured prominently in the Mastectomy Reconstruction Outcomes Consortium (MROC) Study, a five-year prospective, multicenter cohort study of mastectomy reconstruction patients funded by the National Cancer Institute. Over 60 plastic surgeons from 10 centers in the USA and Canada have contributed nearly 4,000 patients to the study, which began in February 2012.
These studies illustrate that the BREAST-Q is scalable to national and international levels and is able to achieve high response rates even with web-based administration. Large-scale studies such as those highlighted above will continue to produce generalizable PROs that clinicians and patients can utilize in future decision making.30
Where do we go from here?
While there has been a focus on breast reconstruction, relatively few studies have utilized the augmentation or reduction/mastopexy modules. The reconstruction module is the most frequently utilized, both in the number of studies and total number of patients, most likely secondary to its duration of availability and the academic and public interest in breast cancer and reconstruction.
However, over 290,000 breast augmentations and over 125,000 breast reductions were performed in 2013 compared to 95,000 breast reconstructions.31 This disparity in usage of the BREAST-Q provides an opportunity for research to enhance understanding of patient satisfaction and HR-QOL for patients undergoing breast augmentation or reduction.
The BREAST-Q’s multiple domains, which provide a near comprehensive view of patient HR-QOL and satisfaction, are also not consistently being utilized to their full potential. Investigators were most interested in the patients’ satisfaction with their breasts, reflecting a common primary endpoint of the reconstructive breast surgeon. Increased attention on the remaining domains, including psychosocial, sexual, and physical well-being, may provide an opportunity to optimize outcomes and deliver comprehensive patient-centered care.
When combined with a rigorous study design, the BREAST-Q can provide reliable evidence based data. The BREAST-Q was used most frequently as a cross sectional tool, assessing patient outcomes at a snapshot in time, often post-operatively. While this design allows a straightforward, singular administration of the BREAST-Q and provides clinicians and researchers the opportunity to compare patient outcomes and quantify potential causal associations between treatment variables, this approach does not provide information regarding changes in outcomes over time.32 Greater usage of prospective study designs, while often more cumbersome, allows data findings to be translated more reliably to patient-centered care.
The BREAST-Q and our review of studies have several limitations. We did not include non-peer reviewed studies, or those from conferences, which may provide additional meaningful clinical data. Also, in order to minimize bias, survey response rates need to be high. While this has been achieved in large-scale studies,9,10 local staff, both clinical and non-clinical, may need practical and methodological support, including training, when they are asked to assist in the collection of BREAST-Q data, which may be an even greater challenge in multicenter trials. Also, inherent in its use is selection bias – patients who fill out questionnaires may be more likely to either be very satisfied or very dissatisfied.33
Our review was not systematic and therefore there may be some omissions. However, we did not set out to conduct a systematic review, as the goal of this article was to provide surgeons with a general overview of the current published surgical research, as opposed to answering a specific research question. In addition, as is the case with most plastic surgery literature, studies that used the BREAST-Q were unlikely to be randomized controlled trials, as it is often not feasible to randomize patients. Furthermore, as the BREAST-Q becomes more ubiquitous, it is important that it is used as intended: changing questions, merging scales, and not using the scoring system as instructed will invalidate results.
Conclusion
The BREAST-Q is a PROM that allows both researchers and clinicians to answer important questions on patient satisfaction and HR-QOL. Its multiple modules and domains allow researchers and clinicians to comprehensively answer clinical questions specific to mastectomy, breast reconstruction, augmentation, and reduction/mastopexy patient populations. The standardized scoring methodology is simple to use and allows for comparisons between studies. The BREAST-Q has greatly improved our ability to understand PROs in patients undergoing breast surgery, and while it has already provided numerous important insights to date, the increased interest in PROs guarantees its continued use and ability to foster new innovations and standards of care.
