Smooth versus Textured Tissue Expanders: Comparison of Outcomes and Complications in 536 Implants.

Background Increasing concerns regarding the safety of textured surface implants have resulted in surgeons transitioning from textured tissue expanders (TEs) to smooth TEs. Given this change has only recently occurred, this study evaluated outcomes between smooth and textured TEs. Methods Women who underwent two-stage breast reconstruction using TEs from 2013 to 2022 were included. TE-specific variables, perioperative information, pain scores, and complications were collected. Chi-squared, t -test, and linear regression analyses were performed. Results A total of 320 patients received a total of 384 textured and 152 smooth TEs. Note that 216 patients received bilateral reconstruction. TEs were removed in 9 cases. No significant differences existed between groups regarding comorbidities. Smooth TEs had a higher proportion of prepectoral placement ( p < 0.001). Smooth TEs had less fills (3 ± 1 vs. 4 ± 2, p < 0.001), shorter expansion periods (60 ± 44 vs. 90 ± 77 days, p < 0.001), smaller expander fill volumes (390 ± 168 vs. 478 ± 177 mL, p < 0.001), and shorter time to exchange (80 ± 43 vs. 104 ± 39 days, p < 0.001). Complication rates between textured and smooth TEs were comparable. Smooth TE had a greater proportion of TE replacements ( p = 0.030). On regression analysis, pain scores were more closely associated with age ( p = 0.018) and TE texture ( p = 0.046). Additional procedures at time of TE exchange ( p < 0.001) and textured TE ( p = 0.017) led to longer operative times. Conclusion As many surgeons have transitioned away from textured implants, our study shows that smooth TEs have similar outcomes to the textured alternatives.

Arm ischemia in a 4-year-old boy with supracondylar fracture of the humerus due to constraining bands over the brachial artery.

Supracondylar humerus fractures are common in children and can compromise the brachial artery in 5% to 15% of cases. A 4-year-old boy with a left supracondylar fracture developed upper extremity ischemia after pinning of the fracture. Computed tomography angiography revealed cutoff of flow in the brachial artery. Intraoperatively, he was found to have bands tethering the artery into the fracture, obstructing the blood flow. The orthopedic pins were removed, and the constraining bands were lysed to free the artery, with reconstitution of flow confirmed by intraoperative angiography. The fracture was reduced and stabilized, and the patient recovered well with normal arterial flow on follow-up ultrasound after 3 months.

Prophylactic Desexualizing Mastectomy for an Intellectually Disabled Woman: Protective Measure or Disregard for Autonomy?

Historically, sterilization of the so-called feeble-minded has been advocated in the name of eugenics. Surrogate decision-making that impacts sexuality of the intellectually disabled presents significant ethical dilemmas. We describe a 19-year-old intellectually disabled woman who presented with her legal decision-maker for surgical correction of her asymmetric chest and hypoplastic breast. The decision-maker requested a mastectomy to make the patient's breasts as inconspicuous as possible, and to reduce the risk of sexual assault and pregnancy. This case covers the ethical considerations on whether or not to prophylactically desexualize an intellectually disabled woman.

Association of Medicaid Expansion with Post-mastectomy Reconstruction Rates.

BACKGROUND: The Affordable Care Act sought to improve access to health care for low-income individuals. This study aimed to assess whether expansion of Medicaid coverage increased rates of post-mastectomy reconstruction (PMR) for patients who had Medicaid or no insurance. METHODS: A retrospective analysis performed through the National Cancer Database examined women who underwent PMR and were uninsured or had Medicaid, private insurance, or Medicare, and whose race/ethnicity, age, and state expansion status were known. Trends in the use of PMR after passage of Medicaid expansion in 2014 were evaluated. RESULTS: In all states and at all time periods, patients with private insurance were about twice as likely to undergo PMR as patients who had Medicaid or no insurance. In 2016, only 28.7 % of patients with Medicaid or no insurance in nonexpansion states underwent PMR (p < 0.001) compared with 38.5 % of patients in expansion states (p < 0.001). Patients in expansion states also have higher levels of education, higher income, and greater likelihood of living in metropolitan areas. Additionally, patients in all states saw an increase in early-stage disease, with a concomitant reduction in late disease, but this change was greater in expansion states than in non-expansion states. CONCLUSIONS: Expansion states have larger proportions of patients undergoing PMR than non-expansion states. This difference stems from significant differences in income, education, comorbidities, race, and location. Large metropolitan areas have the largest number of patients undergoing PMR, whereas rural areas have the least.

Predictors for Prolonged Drain Use Following Autologous Breast Reconstruction.

BACKGROUND: Surgical drains are routinely used following autologous reconstruction, but are often cited as the leading cause of peri-operative discomfort. This study defined routine drain use duration and assessed the risk factors for prolonged breast and abdominal drain use during microvascular breast reconstruction, measures which have never previously been defined. METHODS: Patients who underwent an abdominal microvascular free flap were included. Demographics, comorbidities, and operation-related characteristics were retrospectively collected in a prospectively maintained database. Statistical analysis utilized chi-square independent t-test, and linear regression analyses. RESULTS: One hundred forty-nine patients comprising 233 breast flaps were included. Average breast and abdominal drain duration were 12.9 ± 3.9 and 17.7 ± 8.2 days, respectively. Prolonged breast and abdominal drain duration were defined as drain use beyond the 75th percentile at 14 and 19 days, respectively. Multivariable regression revealed hypertension was associated with an increased breast drain duration by 1.4 days (p = 0.024), axillary dissection with 1.7 days (p = 0.026), African-American race with 3.1 days (p < 0.001), Hispanic race with 1.6 days (p = 0.029), return to the OR with 3.2 days (p = 0.004), and each point increase in BMI with 0.1 days (p = 0.028). For abdominal drains, each point increase in BMI was associated with an increased abdominal drain duration by 0.3 days (p = 0.011), infection with 14.4 days (p < 0.001), and return to the OR with 5.7 days (p = 0.007). CONCLUSION: Elevated BMI, hypertension, and axillary dissection increase risk for prolonged breast drain requirement in autologous reconstruction. African-American and Hispanic populations experience prolonged breast drain requirement after controlling for other factors, warranting further study.

Comparison of Autologous Breast Reconstruction Complications by Type of Neoadjuvant Chemotherapy Regimen.

BACKGROUND: Neoadjuvant chemotherapy before mastectomy helps reduce tumor burden and pathologic response in breast cancer. Limited evidence exists regarding how neoadjuvant chemotherapy impacts outcomes following microvascular breast reconstruction. This study examines the effects of neoadjuvant chemotherapy regimens and schedules on microvascular breast reconstruction complication rates and also assesses the effects of neoadjuvant chemotherapy on circulating immune cells related to wound healing. METHODS: Patients who underwent neoadjuvant chemotherapy and microvascular breast reconstruction at Yale New Haven Hospital between 2013 and 2018 were identified. Demographic variables, oncologic history, chemotherapy regimens, and complication profiles were collected. Chemotherapy regimens were stratified by inclusion of anthracycline and order of taxane administration. Chi-square, Fisher's exact, and t tests were used for univariate analysis. Multivariate binary logistic regression was used to control for covariates. RESULTS: One hundred patients met inclusion criteria. On multivariate analysis, the administration of taxane first in an anthracycline-containing chemotherapy sequence was associated with increased complications (OR, 3.521; p = 0.012), particularly fat necrosis (OR, 2.481; p = 0.040). In the logistic regression model evaluating the effect of the taxane-first regimen on complication rates, the area under the curve was estimated to be 0.760 (p < 0.0001), particularly fat necrosis 0.635 (p < 0.05). The dosage of chemotherapy, number of days between neoadjuvant chemotherapy completion and surgery, and number of circulating immune cells did not significantly differ among patients who experienced complications. CONCLUSIONS: Taxane-first, anthracycline-containing neoadjuvant chemotherapy regimens were associated with increased complications, particularly fat necrosis. The increased postreconstruction complication risk must be weighed against the benefits of taxane-first regimens in improving tumor outcome. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

A Comparison of BREAST-Q Scores between Prepectoral and Subpectoral Direct-to-Implant Breast Reconstruction.

BACKGROUND: Subpectoral breast implant placement has in recent history predominated in breast reconstruction, but there has been more recent adoption of prepectoral implant reconstruction. There has been limited study to date of patient-reported outcomes comparing the two techniques. METHODS: Patients who underwent direct-to-implant breast reconstruction between 2013 and 2018 were included in this retrospective cohort study. Eligible patients were asked to complete BREAST-Q domains comparing quality of life and satisfaction. Descriptive, t test, chi-square test, and multivariate linear regression analyses were performed to compare BREAST-Q scores. Significance was defined as p ≤ 0.05. RESULTS: There were 64 patients (114 breasts) who underwent prepectoral reconstruction and 37 patients (68 breasts) who underwent subpectoral reconstruction. Among the 101 women (182 breasts), there were no significant differences between BREAST-Q scores and implant position for the Satisfaction with Breasts domain (adjusted p = 0.819), Psychosocial Well-being domain (adjusted p = 0.206), or Physical Well-being Chest domain (adjusted p = 0.110). The subpectoral implant cohort was associated with higher scores, 53 versus 47, for the Sexual Well-being module (adjusted p = 0.001). CONCLUSIONS: Patients undergoing direct-to-implant breast reconstruction had comparable BREAST-Q satisfaction scores for most modules regardless of implant plane. The subpectoral implant cohort scored higher for sexual well-being.

Impact of insurance payer and socioeconomic status on type of autologous breast reconstruction.

INTRODUCTION: Autologous breast reconstruction has evolved from more morbid procedures that sacrificed the abdominal muscle (the TRAM or transverse rectus abdominus muscle flap) to "perforator" flaps. Commercial insurers recognized the higher technical demand of perforator flaps by creating procedural codes with higher professional fees. This study examined whether procedure code discrepancies between insurance payers disproportionally incentivize perforator flaps among the commercially insured. METHODS: Autologous breast reconstructions identified from the National Inpatient Sample (NIS) were subdivided into microvascular perforator (85.74, 85.75, 85.76), microvascular TRAM (85.73), and pedicled TRAM flaps (85.72). Demographics, comorbidities and access to care were compared. A logistic regression comparing microvascular reconstructions only was used to identify predictors for perforator flap reconstruction. RESULTS: A total of 66,968 cases of autologous breast reconstruction were identified. Perforator flaps were more likely among the commercially insured (p < 0.001) and higher insurance quartiles (p < 0.001).When comparing microvascular reconstruction, perforator flaps were 1.72 (p < 0.001) times more likely among the commercially insured. As compared to the lowest income quartile, the fourth quartile had an odds ratio of 1.36 (p < 0.001) for perforator flap reconstruction. CONCLUSION: The presence of a separate perforator flap billing code among the commercially insured may be exacerbating existing socioeconomic disparities in breast cancer reconstruction.

Assessing Interobserver Variability of Cosmetic Outcome Assessment in Breast Cancer Patients Undergoing Breast-Conservation Surgery.

BACKGROUND: Inter-rater reliability between breast surgical oncologists and reconstructive surgeons using cosmesis scales, and the correlation between their observations and patients' own subjective assessments, is poorly understood. METHODS: Patients undergoing BCS in a prospective trial rated their cosmetic outcome on a Likert scale (poor/fair/good/excellent) at the postoperative and 1-year time points; photographs were also taken. Three breast surgical oncologists (not involved in these cases) and two reconstructive surgeons were asked to independently rate cosmesis using the Harvard/NSABP/RTOG scale. RESULTS: Overall, 55 and 17 patients had photographs and Likert self-evaluations at the postoperative and 1-year time points, respectively. There was poor agreement between surgeon and patient ratings postoperatively [kappas - 0.042 (p = 0.659), 0.069 (p = 0.226), and 0.076 (p = 0.090) for the breast surgical oncologists; and 0.018 (p = 0.689) and 0.112 (p = 0.145) for the reconstructive surgeons], and poor interobserver agreement between surgeons of the same specialty (kappa - 0.087, 95% confidence interval [CI] - 0.091 to - 0.082, p = 0.223 for breast surgical oncologists; and kappa - 0.150, 95% CI - 0.157 to - 0.144, p = 0.150, for reconstructive surgeons). At 1 year, the interobserver agreement between breast surgical oncologists was better (kappa 0.507, 95% CI 0.501-0.512, p < 0.001); however, there was still poor correlation between the reconstructive surgeons (kappa - 0.040, 95% CI - 0.049 to - 0.031, p = 0.772). Agreement between surgeon and patient ratings remained poor at this time point [kappas - 0.115 (p = 0.477), 0.177 (p = 0.245), and 0.101 (p = 0.475) for breast surgical oncologists; and 0.335 (p = 0.037) and -0.118 (p = 0.221) for reconstructive surgeons]. CONCLUSION: Despite gradation scales for measuring cosmesis after BCS, high levels of agreement between surgeons is lacking and these do not always reflect patients' subjective assessments.

Comparing complications in irradiated and non-irradiated free-flaps in patients with bilateral immediate breast reconstruction and unilateral post-mastectomy radiotherapy.

BACKGROUND: Numerous studies have evaluated the effect of post-mastectomy radiotherapy (PMRT) on autologous breast reconstruction, but the variability of PMRT regimens and inadequate controls have made results difficult to interpret. Therefore, in this study, irradiated free-flaps are compared to non-irradiated internal controls in patients who underwent immediate bilateral reconstruction followed by unilateral PMRT to better delineate the effect of PMRT. The role of regional nodal irradiation (RNI) is also specifically assessed. METHODS: Appropriate patients were identified through retrospective review. Complications such as fat necrosis, fibrosis, infection, delayed healing, and flap loss, as well as revision surgeries, among the irradiated free-flaps were compared to those on the contralateral non-irradiated side. Additional analyses were performed to evaluate the effect of patient demographics and treatment characteristics, such as RNI, on complications involving the irradiated free-flaps. RESULTS: Seventy-three women were included. There was no significant difference between complication rates for the irradiated and non-irradiated free-flaps (39.7% vs. 38.4%, p = .78), although irradiated free-flaps were more likely to have fibrosis (17.0% vs. 0.0%; p < .0001) and multiple complications (9.6% vs. 0.0%; p = .02). Both groups underwent a similar number of revision surgeries (42.5% vs. 41.1%; p = .29). Looking at the irradiated free-flaps, internal mammary node (IMN) irradiation was the only factor predictive of complications (IRR 3.80, CI 1.32-10.97; p = .01). CONCLUSIONS: PMRT may contribute to free-flap fibrosis, but does not appear to affect the overall risk of complications or revision surgeries. However, additional counseling is warranted if IMN irradiation is likely, as it is potentially associated with increased complications.

Abdominal subcutaneous fat thickness as a substitute for BMI in predicting complications in abdominally-based autologous breast reconstruction.

INTRODUCTION: Patient selection for autologous tissue transfer for postmastectomy breast reconstruction often utilizes body mass index (BMI) to risk stratify patients, though it only estimates fat content and does not address fat distribution. This study aims to identify a measurement of abdominal subcutaneous fat thickness (ASFT) from preoperative computed tomography (CT) angiography imaging to better predict complications. METHODS: A retrospective review of patients who underwent an abdominal microvascular free flap breast reconstruction was performed. The average of the bilateral distances from the lateral border of the rectus abdominus to the most proximal point of the dermis at the L4-L5 space was measured on preoperative imaging to estimate ASFT. This measurement was compared to BMI in regards to correlation with any complication, major or minor complications, and donor or recipient site complications. Statistical analysis utilized point-biserial correlations and multivariable logistic regression analyses. RESULTS: Three hundred and nine cases comprising a total of 496 breast reconstructions were identified. BMI did not correlate with any of the grouped complications, while ASFT correlated with occurrence of any complication (p = .003), minor complications (p = .001), and recipient site complications (p = .001). Further analysis revealed ASFT is specifically correlated with fat necrosis (p = .005). In independent multivariable regression models, both BMI (p = .011) and ASFT (p = .001) were significant predictors of fat necrosis. The ASFT model had a BIC of 335.42 compared to the BMI model with a value of 340.89, with smaller numbers representing more predictive models. CONCLUSION: Estimation of ASFT is easily performed and is a significantly better predictor of flap fat necrosis than BMI.

Risk Factors for Lymphedema After Breast Conservation Therapy and Oncoplastic Reduction.

BACKGROUND: Lymphedema is a known complication after the surgical management of breast cancer, yet the incidence is poorly defined after breast conserving therapy and oncoplastic reduction. The primary aim of this study was to define lymphedema incidence in this population. Furthermore, we sought to correlate demographic factors, surgical approach, and complementary treatment modalities with incidence. METHODS: Data were collected retrospectively on patients who underwent breast conserving therapy at our institution from 2012 to 2015 with greater than 1 year of follow-up. Patients were excluded if they underwent breast surgery before treatment, completion mastectomy, delayed breast reconstruction, or delayed breast reduction. RESULTS: Five hundred and eighty-four patients met study criteria with a 11% lymphedema rate. Patients developing lymphedema had higher preoperative body mass index (P = 0.02), larger breast mass resection volume (P < 0.01), higher rate of axillary dissection (P < 0.01), increased rate of adjuvant whole-breast radiation (P = 0.03), supraclavicular radiation (P < 0.01), axillary radiation (P < 0.01), and neoadjuvant medical therapy (P < 0.01). Multivariate analysis showed breast specimen mass, axillary radiation, and neoadjuvant medical therapy, which were associated with lymphedema (P < 0.05). There was no difference in lymphedema incidence between partial mastectomy and oncoplastic reduction cohorts with independent multivariate analyses for each showing axillary radiation and neoadjuvant medical therapy were significantly associated with lymphedema (P < 0.05), although breast specimen mass was not. CONCLUSIONS: Elevated preoperative body mass index, radiation, axillary dissection, and neoadjuvant medical therapy are associated with an increased risk of lymphedema after breast conserving surgery. Oncoplastic reconstruction is not a risk factor for lymphedema.

Surgical Outcomes of Mastectomy with Immediate Autologous Reconstruction Followed by Radiation.

INTRODUCTION: Timing of autologous reconstruction relative to postmastectomy radiation therapy (PMRT) is debated. Benefits of immediate reconstruction must be weighed against a possibly heightened risk of complications from flap irradiation. We reviewed flap outcomes after single operation plus PMRT in a large institutional cohort. METHODS: Medical records were reviewed for women who underwent simultaneous mastectomy-autologous reconstruction with PMRT from 2007 to 2016. Primary endpoints were rates and types of radiation-related flap complications and reoperations, whose predictors were assessed by multivariable analysis. A p value < 0.10 was deemed significant to avoid type II error. Non-parametric logistic regression generated a model of PMRT timing associated with probabilities of complications and reoperations. RESULTS: One-hundred and thirty women underwent 208 mastectomy reconstruction operations, with a median follow up of 35.1 months (interquartile range 23.6-56.5). Forty-seven (36.2%) women experienced radiation-related complications, commonly fat necrosis (44.1%) and chest wall asymmetry (28.8%). Complications were higher among women who received PMRT < 3 months after surgery (46.8% for < 3 months vs. 29.3% for ≥ 3 months; p = 0.06), most of whom received neoadjuvant chemotherapy, and among women treated with internal mammary nodal (IMN) radiation (65.2% vs. 26.4%; p < 0.01); IMN radiation remained strongly associated in multivariable analysis (odds ratio [OR] 5.24; p < 0.01). Thirty-two (24.6%) women underwent 70 reoperations, commonly fat grafting (51.9%) and fat necrosis excision (17.1%). Reoperations were higher among women who received PMRT < 3 months after surgery (48.9 for < 3 months vs. 36.6 for ≥ 3 months; p = 0.19), which was significantly associated in multivariable analysis (OR 0.42; p = 0.08 for ≥ 3 months). The probabilities of complications and reoperations were lowest when PMRT was administered ≥ 3 months after surgery. CONCLUSIONS: Among a large institutional cohort, immediate autologous reconstruction was associated with similar rates of adverse flap outcomes as historically reported alternatively sequenced protocols. IMN radiation increased risk, while PMRT ≥ 3 months after surgery decreased risk. Additional studies are needed to elaborate the impact of IMN radiation and early PMRT in immediate versus delayed autologous reconstruction.

Worse overall health status negatively impacts satisfaction with breast reconstruction.

BACKGROUND: BREAST-Q is a validated measure of patient satisfaction and health-related quality of life following breast surgery. Limited evidence exists with regard to the influence of preoperative overall health status on BREAST-Q outcomes. The American Society of Anesthesiologists (ASA) physical status classification is representative of preoperative overall health and its impact on patient-reported outcomes can be assessed. METHODS: Patients who received breast reconstruction at Yale New Haven Hospital between 2013 and 2018 and completed the BREAST-Q were enrolled in the study. Associations between BREAST-Q scores within modules and between modules and ASA were analyzed. Pearson's correlation and Spearman's Rho were used to characterize correlations between patient factors and BREAST-Q scores. Significantly correlated factors were entered into a general linear model (GLM) to control for confounding variables and isolate the effect of ASA on BREAST-Q scores. RESULTS: A total of 1136 patients underwent breast reconstruction of whom 489 patients completed the BREAST-Q. Increasing ASA indicative of worsening overall health was associated with a decreased BREAST-Q score for all modules except Physical Well-being of the Abdomen (p<0.01 to p = 0.029). In a GLM controlling for relevant covariates, ASA remained a significant contributor for all modules except Physical Well-being of the Chest (p<0.01 to p = 0.021). BREAST-Q scores decreased by approximately twice as much from ASA 1 to 2 compared to ASA 2 to 3. CONCLUSION: ASA classification is an independent predictor of BREAST-Q patient-reported outcomes following breast reconstruction. Communicating the potential impact of overall health may help reduce the discrepancy in postoperative satisfaction across ASA classifications.

Patients with psychiatric illness report worse patient-reported outcomes and receive lower rates of autologous breast reconstruction.

Psychiatric well-being impacts on general satisfaction and quality of life. This study explored how the presence of psychiatric diagnoses affects patient-reported outcomes in breast reconstruction and on selection of reconstructive modality. Patients who received breast reconstruction at a tertiary hospital between 2013 and 2018 and completed the BREAST-Q survey were included. BREAST-Q module scores were compared between patients who had a psychiatric diagnosis at presentation and the remaining cohort using t tests. General linear models (GLMs) were used to control for confounding factors. A chi-squared test was used to assess the effect on reconstructive modality, and binary logistic regression was used to control for confounding factors. Of the 471 patients included, 93 (19.7%) had at least one psychiatric diagnosis. Cohorts did not differ significantly by age, BMI, race, ASA classification, or insurance status. Patients with a psychiatric diagnosis experienced a decrease in BREAST-Q scores for the Psychosocial Wellbeing (B = 9.16, P = .001) and Sexual Wellbeing (B = 9.29, P = .025) modules. On binary logistic regression, patients with a psychiatric diagnosis were less likely to receive autologous reconstruction compared with implant reconstruction (OR = 0.489, P = .010). The presence of psychiatric diagnoses is an independent predictor of decreased BREAST-Q. Furthermore, there is a significant disparity in modality of reconstruction given to patients with psychiatric diagnoses. Further study is needed to evaluate interventions to improve satisfaction among at-risk populations and evaluate the reason for low autologous reconstruction in this population.

Impact of socioeconomic status on psychological functioning in survivorship following breast cancer and reconstruction.

Socioeconomic status (SES) remains an important population health risk factor and impacts a patient's experience of care during breast cancer. This study explored the relationship between SES and quality of life and satisfaction in survivorship following breast cancer and reconstruction. All patients underwent breast reconstruction at a single academic center from 2013 to 2017. Patients completed the five quality of life and satisfaction domains of the BREAST-Q, a validated patient-reported outcome measure. Estimated home value using a web-based real estate website was used to approximate a patient's socioeconomic status. Correlations were evaluated using Pearson's correlation methods, where appropriate, as well as analysis of covariance. Data were stratified for comparison utilizing t tests and linear regression models. Significance was defined as P ≤ .05. Four hundred patients underwent 711 breast reconstructions during the study time period. Satisfaction with the breast (P = .038) and psychosocial well-being (P = .012) had significant positive correlations with increasing socioeconomic status. When stratifying patients' socioeconomic status into thirds, the upper third had significantly higher psychosocial well-being (P = .001), satisfaction with breasts (P = .010), and physical well-being of the chest (P = .001) than the lower third. Significance persisted even after controlling for cancer stage, treatment, complications, and baseline comorbidities. Higher socioeconomic status is associated with greater satisfaction with breast reconstruction and psychosocial well-being following breast cancer treatment. Providing added social, psychological, and emotional support networks may be beneficial long after the initial cancer treatment and reconstruction are complete. Patients of lower socioeconomic status may benefit from additional resources.

Impact of Insurance Payer on Type of Breast Reconstruction Performed.

BACKGROUND: The impact of insurance and socioeconomic status on breast reconstruction modalities when access to care is controlled is unknown. METHODS: Records for patients who underwent breast reconstruction at an academic medical center between 2013 and 2017 were reviewed and analyzed using chi-square analysis and logistic regression. RESULTS: One thousand six hundred eighty-three breast reconstructions were analyzed. The commercially insured were more likely to undergo microvascular autologous breast reconstruction (44.4 percent versus 31.3 percent; p < 0.001), with an odds ratio of 2.22, whereas patients with Medicare and Medicaid were significantly more likely to receive tissue expander/implant breast reconstruction, with an odds ratio of 1.42 (41.7 percent versus 47.7 percent; p = 0.013). Comparing all patients with microvascular reconstruction, the commercially insured were more likely to receive a perforator flap (79.7 percent versus 55.3 percent versus 43.9 percent), with an odds ratio of 4.23 (p < 0.001). When stratifying patients by median household income, those in the highest income quartile were most likely to receive a perforator flap (82.1 percent) (p < 0.001), whereas those in the lowest income quartile were most likely to receive a muscle-sparing transverse rectus abdominis myocutaneous flap (36.4 percent) (p < 0.001). CONCLUSIONS: Patients at the same academic medical center had significantly different breast reconstruction modalities when stratified by insurance and household income. Despite similar access to care, differences in insurance types may favor higher rates of perforator flap breast reconstruction among the commercially insured. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.

Breast reconstruction patterns and outcomes in academic and community practices within a single institution.

Breast reconstruction is a common procedure that is performed in both community and academic settings. At Yale-New Haven Hospital (YNHH), both academic (AP) and community-based (CP) plastic surgeons perform breast reconstructions. We aim to compare practice patterns in breast reconstruction between two practice environments within a single institution. A retrospective chart review of all breast reconstructions at YNHH between 2013 and 2018 was performed. Data collected included demographics, preoperative history, and postoperative outcomes. Results were further subdivided by practice setting. A total of 1045 patients (1683 breasts) underwent breast reconstruction during the study period. About 52.8% were performed by AP while 47.2% were performed by CP. CP had higher rates of autologous reconstruction (P < .001) and nipple-sparing mastectomy (P < .0001). Age and BMI were similar between the cohorts. However, patients cared for by AP had 2.6% increased prevalence of diabetes (P = .064), 5.5% greater prevalence of psychiatric diagnoses (P = .004), and 7.1% higher open abdominal surgery rates (P < .001). Outcomes were similar between the groups except for higher infection rates (P = .027) and explant rates (P = .003) in the CP cohort. When evaluating insurance status, the AP cohort had 30.5% fewer patients with commercial insurance, 16.7% more patients with Medicaid and 6.1% more patients with Medicare (P < .001). Within our institution, academic and community-based plastic surgeons perform breast reconstruction with overall similar complication rates. Patients treated by AP have a higher rate of preoperative medical and psychiatric comorbidities. Patients treated by CP have higher rates of infection and implant explant. AP plastic surgeons care for a significantly higher rate of Medicare and Medicaid patients with proportionally fewer patients with commercial insurance.

Complication Profiles by Mastectomy Indication in Tissue Expander Breast Reconstruction.

BACKGROUND: Two-stage implant breast reconstruction is the most commonly performed breast reconstruction procedure. Limited data exist regarding reconstruction complication rates examined by mastectomy indication. METHODS: Patients who underwent two-stage implant breast reconstruction at Yale New Haven Hospital from 2011 to 2017 were included in the study. Perioperative complications were compared. Chi-square analysis, t tests, and Fisher's exact tests were used to determine significant associations. A binary logistic regression was used to determine variables with a significant impact on the likelihood of mastectomy flap necrosis. RESULTS: Between 2011 and 2017, complete perioperative records were available for 141 patients who underwent 226 mastectomies followed by two-stage tissue expander/permanent implant reconstruction. Of the 226 mastectomies, 134 were therapeutic and 92 were prophylactic. On regression analysis, there were no significant differences in demographics, comorbidities, or mastectomy and reconstructive details between the two breast groups except for there being more modified radical mastectomies in therapeutic breasts (p = 0.003). When comparing complications, there was a significantly higher risk of mastectomy flap necrosis in the therapeutic group (p = 0.017). Therapeutic mastectomies had a 9.5 times higher risk of mastectomy flap necrosis than prophylactic mastectomies when adjusted for confounding variables. There were no significant differences in other reconstructive complications between the two groups. CONCLUSIONS: Patients undergoing therapeutic mastectomies have a significantly higher risk of mastectomy flap necrosis than those undergoing prophylactic mastectomies. Although the underlying cause still needs to be determined, differences in technique may be related to mastectomy flap necrosis. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, II.
