Abstract
BACKGROUND Operative microscopes are traditionally draped in single-use plastic to prevent infection theoretically. The necessity of this routine in breast free flap surgery is unclear. Alternatively, sterile wrapping of microscope handles would reduce operating room waste and provide a more cost-effective and environmentally sustainable approach to sterility. This study aimed to determine whether the draping technique used during abdominally based free flaps (Ab-FF) influenced the rate of surgical site infections. METHODS We conducted a retrospective review of Ab-FF performed consecutively between March 2017 and August 2022. Patient demographics, comorbidities, perioperative data, and postoperative complications were collected. The primary outcomes included postoperative surgical site infections and environmental impact. RESULTS Of the 281 identified breasts reconstructed with Ab-FF, operating microscopes were sterilely covered with microscope drapes (n = 215) or handle covers (n = 66) composed of polyethylene-based plastic. Overall, postoperative infections occurred in 9.3% of cases (n = 26) in either the recipient breast (n = 11, 3.9%) or abdominal donor site (n = 15, 5.3%), primarily due to S. aureus and Streptococcus species . The handle (n = 6, 9.1%) and drape (n = 20, 9.3%) cohorts had similar infection rates with no sequelae of operative complications. In multivariate analysis, radiation was the only independent predictor of postoperative infection, while bilateral reconstructions were independently protective. Replacing a microscope drape with a handle reduces carbon emissions by 1276 grams of CO 2 and direct costs by $7.84 per item. CONCLUSIONS The principles of "Lean and Green" surgery prioritize reducing operating room generated waste to achieve financial and environmental sustainability. This cohort study of 281 breast free flaps demonstrates that switching from whole microscope draping to handle wrapping was not associated with an increased rate or odds of infection. Adopting a microscope handle wrapping protocol decreased the carbon footprint and operative costs. The results of this study offer evidence to support adoption and further exploration of pragmatic, cost-effective, and sustainable approaches to microsurgical breast reconstruction.

The efficacy of prolonged antibiotic prophylaxis in total breast reconstruction with Autologous Fat Transfer (AFT): A retrospective cohort study. J Plast Reconstr Aesthet Surg 2024; 97:221-229. [PMID: 39168031 DOI: 10.1016/j.bjps.2024.07.041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2024] [Revised: 07/21/2024] [Accepted: 07/22/2024] [Indexed: 08/23/2024]
Abstract
BACKGROUND Autologous fat transfer (AFT) is increasingly adopted as another total breast reconstruction option. The aim of this study was to investigate the efficacy of prolonged antibiotic treatment on the onset of surgical site infections (SSIs) in patients treated with AFT for total breast reconstruction. METHODS This retrospective cohort study was conducted on patients who received AFT for total breast reconstruction, with antibiotic prophylaxis during their (multiple) AFT procedure(s) from 9 December 2020 to 10 October 2023. Patients were divided into 2 groups according to their prophylactic antibiotic regimen. The primary outcome was analyzed, including the cumulative incidence, the relative risk (RR), the absolute risk reduction (ARR), and the number needed to treat (NNT). For the secondary outcome, a multilevel logistic regression analysis was performed. RESULTS Seven hundred sixty-five surgeries in 205 patients were analyzed. Six hundred twenty-four surgeries on 168 patients had perioperative antibiotic prophylaxis in combination with postoperative antibiotic prophylaxis administered (group 1). One hundred forty-one surgeries on 37 patients had only perioperative antibiotic prophylaxis administered (group 2). The RR was 0.68 (95% confidence interval [CI]; 0.14-3.31) of a SSI when receiving peri- and postoperative antibiotic prophylaxis in comparison with treatment with only perioperative prophylaxis. The ARR was 0.46% (95% CI; -1.40 to 2.32) with a NNT of 219 patients. CONCLUSION Prolonged antibiotic prophylaxis is ineffective for patients who receive total breast reconstruction with AFT. This study showed no statistically significant difference in SSIs of the reconstructed breast after receiving prolonged antibiotic treatment in comparison with single-shot perioperative antibiotic prophylaxis.

Abstract
BACKGROUND Depression is notably common among patients who have undergone mastectomy. Several post-mastectomy patients opt for elective breast reconstruction. However, evidence on the influence of preoperative depression on breast reconstruction outcomes remains limited. This study aimed to evaluate the effect of preoperative depression on the short-term outcomes of autologous breast reconstruction (ABR) and implant-based breast reconstruction (IBR) using a comprehensive national registry. METHODS Patients who underwent ABR or IBR were identified from the national inpatient sample from Q4 2015-2020. Multivariable logistic regressions were used to compare in-hospital outcomes between the patients with and without depression, adjusted for demographics, primary payer status, hospital characteristics, and comorbidities. RESULTS Among the 12,984 patients who underwent ABR, 1578 (12 %) had depression whereas 1980 (11 %) out of 17,963 patients who underwent IBR had depression. In ABR and IBR, preoperative depression was associated with higher superficial wound complications (ABR, aOR = 1.386, 95 % CI = 1.035-1.856, p = 0.03; IBR, aOR = 1.281, 95 % CI = 1.001-1.638, p = 0.04), hemorrhage/hematoma (ABR, aOR = 1.164, 95 % CI = 1.010-1.355, p = 0.04; IBR, aOR = 1.614, 95 % CI = 1.279-2.037, p < 0.01), and longer hospital length of stay (p < 0.01). In ABR, patients with depression had higher incidences of infection (aOR = 1.906, 95 % CI = 1.246-2.917, p < 0.01) and sepsis (aOR = 15.609, 95 % CI = 1.411-172.65, p = 0.03). In IBR, patients with depression had higher risks of capsular contracture (aOR = 1.477, 95 % CI = 1.105-1.976, p = 0.01) and seroma (aOR = 1.489, 95 % CI = 1.005-2.208, p = 0.04). CONCLUSION Preoperative depression is independently associated with major morbidities after ABR and IBR. Preoperative screening for depression can be beneficial. Findings from this study can facilitate preoperative risk stratification and post-operative care for patients with depression.

Abstract
BACKGROUND Combining multiple surgical procedures into a single operative session is widespread in the field of plastic surgery; however, the implications of this practice are not fully understood. OBJECTIVES This study compared 30-day complication rates associated with combined plastic surgery procedures with the rates for index procedures. METHODS This retrospective cohort analysis utilized the Tracking Operations and Outcomes for Plastic Surgeons database from 2016 to 2020 to identify the 3 most frequent combinations of augmentation mammaplasty, reduction mammaplasty, trunk liposuction, mastopexy, and abdominoplasty. RESULTS The 30-day overall complication rate was 5.0% (1400 of 26,771 patients), with a higher complication rate for combined procedures compared with index (7.6% vs 4.2%, adjusted odd ratio [aOR], 1.91 [95% CI, 1.61-2.27], P < .001). There were no significant differences in complication rates for abdominoplasty or mastopexy combinations compared with index. Complication rates for reduction mammaplasty combinations compared with index were not statistically different after controlling for demographics (aOR, 1.02 [95% CI, 0.61-1.64], P = .93). Higher rates of minor and major complications were observed for combinations of trunk liposuction (aOR, 4.84 [95% CI, 3.31-7.21), P < .001) and augmentation mammaplasty (aOR, 1.60 [95% CI 1.13-2.22], P = .007) compared with index. CONCLUSIONS Combinations with trunk liposuction or augmentation mammaplasty present with increased risk of complications compared with index, controlling for demographics. Abdominoplasty and mastopexy may be combined with other plastic surgery procedures without increased risk to patients. The complication risk of reduction mammaplasty combinations is mediated by other variables, suggesting the need for shared surgical decision-making when recommending these combinations to patients.

Abstract
Although prophylactic antibiotic use following autologous breast reconstruction post-mastectomy is a common practice, there is no consensus in the literature regarding its duration. Antibiotic stewardship is important to minimise multi-resistant organisms as well as mitigate the associated side effects. Currently, there are no published guidelines regarding the duration of prophylactic antibiotics in autologous breast reconstruction surgery following mastectomy. The authors searched the online literature regarding the administration of antibiotics for autologous breast reconstruction surgery post-mastectomy. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed. The primary outcome measure was the incidence of surgical site infections (SSIs). Three studies met the inclusion criteria and included a total of 1,400 patients. Overall, 101 (7.2%) SSIs were observed. There was no significant difference in the rate of SSIs when comparing the use of antibiotics for less than or longer than 24 hours postoperatively (odds ratio = 1.434, p = 0.124). There is no significant difference between SSIs with the use of antibiotics for longer than 24 hours when compared to less than 24 hours. Further studies in the form of randomised controlled trials are required to assess the effects of prophylactic antibiotic duration in autologous breast reconstruction following mastectomy.

Abstract
Breast implants are widely used for reconstructive and/or cosmetic purposes. Inflammations and infections of breast implants represent important complications in clinical practice. The proper management of complications is necessary: diagnostic imaging plays a key role in detecting sites of inflammation and/or infection. The present review aims to illustrate the radiological findings of these conditions with different imaging techniques, such as mammography (MX), ultrasound (US), magnetic resonance imaging (MRI), and nuclear medicine imaging. A knowledge of these findings is essential for radiologists and nuclear medicine physicians to provide helpful information for the clinical management of these complications.

Abstract
Antibiotic prophylaxis is frequently used in plastic surgery procedures, despite the generally low rates of infection and few guidelines on the practice. The increasing prevalence of bacterial resistance to antibiotics calls for a reduction in unnecessary antibiotic use. The aim of this review was to create an updated summary of the available data on the effectiveness of antibiotic prophylaxis in reducing the postoperative infection in clean and clean-contaminated plastic surgery. A systematic literature search was performed on the databases Medline, Web of Science, and Scopus, limited to articles published January 2000 onward. Randomized controlled trials (RCTs) were included in the primary review, whereas older RCTs and other studies were sought if 2 or fewer relevant RCTs were identified. Overall, 28 relevant RCTs, 2 nonrandomized trials, and 15 cohort studies were identified. Although the number of studies for each type of surgery is limited, the data suggest that prophylactic systemic antibiotic may be unnecessary in noncontaminated facial plastic surgery, reduction mammaplasty, and breast augmentation. In addition, no benefit is apparent from extending the antibiotic prophylaxis over 24 h in rhinoplasty, aerodigestive tract reconstruction, and breast reconstruction. No studies assessing the necessity of antibiotic prophylaxis in abdominoplasty, lipotransfer, soft tissue tumor surgery, or gender affirmation surgery were identified. In conclusion, limited data are available on the effectiveness of antibiotic prophylaxis in clean and clean-contaminated plastic surgery. More studies on this topic are needed before strong recommendations can be made on the use of antibiotics in this setting.

Abstract
BACKGROUND Autologous breast reconstruction has become standard of care, but there is no consensus on prophylactic antibiotic regimens for this surgical procedure. This review aims to present evidence on the best prophylactic antibiotic protocol to lower the risk of surgical site infections in autologous breast reconstructions. METHODS The search was performed in PubMed, EMBASE, Web of Science, and Cochrane Library on 25th of January 2022. Data on the number of surgical site infections, breast reconstruction type (pedicled or free flap) and reconstruction timing (immediate or delayed), as well as data on the type, dose, route of administration, timing, and duration of antibiotic treatment were extracted. All included articles were additionally assessed for potential risk of bias by using the revised RTI Item Bank tool. RESULTS 12 studies were included in this review. No evidence is found that giving post-operative antibiotics for a prolonged period longer than 24 h after surgery is useful in lowering infection rates. This review could not distinguish between the best choice of antimicrobial agent. DISCUSSION Although this is the first study that collected current evidence on this topic, the quality of evidence is limited due to a small number of available studies (N = 12) with small study populations. The included studies have high heterogeneity, no adjustment for confounding, and interchangeably used definitions. Future research is highly recommended with predefined definitions, and a sufficient number of included patients. CONCLUSION Antibiotic prophylaxis up to a maximum of 24 h is useful in lowering infection rates in autologous breast reconstructions.

Abstract
There is no consensus on the duration of prophylactic antibiotic use for autologous breast reconstruction after mastectomy. We attempted to standardize the use of prophylactic antibiotics after mastectomy using a deep inferior epigastric perforator flap for the breast reconstruction procedure. Methods This retrospective case series included 108 patients who underwent immediate breast reconstruction with a deep inferior epigastric perforator flap at the Ditmanson Medical Foundation Chia-Yi Christian Hospital between 2012 and 2019. Patients were divided into three groups based on the duration of prophylactic antibiotic administration (1, 3, and >7 days) for patients with drains. Data were analyzed between January and April 2021. Results The prevalence of surgical site infection in the breast was 0.93% (1/108), and in the abdomen it was 0%. The patient groups did not differ by age, body mass index, smoking status, or neoadjuvant chemotherapy. Only one patient experienced surgical site infection in the breast after half-deep necrosis of the inferior epigastric perforator flap. There were no significant differences in surgical site infection based on the duration of prophylactic antibiotic use. The operation time, methods of breast surgery, volume of fluid drainage in the first 3 days of the abdominal and breast drains, and day of removal of the abdominal and breast drains did not affect surgical site infection. Conclusion Based on these data, we do not recommend extending prophylactic antibiotics beyond 24 hours in deep inferior epigastric perforator reconstruction.

Abstract
BACKGROUND The popularity of aesthetic breast surgery in China results in greater demand for assessing risk factors for complications and mortality. OBJECTIVES To determine the incidence and independent risk factors for postoperative complications following aesthetic breast surgery in China. METHODS A retrospective cohort study on 4973 patients who had aesthetic breast surgery between 2012 and 2021 was performed. Postoperative complications include minor complications (incision healing impaired, hematoma, or fat liquefaction) and surgical site infection (SSI), which were recorded within 30 days after surgery. The follow-up time was expanded to 1 year only after prosthesis implantation procedures. Potential risk factors including age, weight, length of hospital stay, operation time, volume resection, incision location, and other clinical profile information were evaluated. RESULTS Among 4973 patients who underwent aesthetic breast surgery, the minor complication rate was 0.54%, and SSI was 0.68%. Augmentation with prosthesis implantation had the highest SSI rate (4.23%), which was significantly associated with increasing age (relative risk [RR] 1.12; P < 0.01) and periareolar incision (RR 5.87, P < 0.01). After augmentation with autologous fat transplantation, postoperative antibiotic use (RR 6.65, P < 0.01) was an independent risk factor for SSI. After adjusting for weight, volume resection over 1500 g (RR 14.7, P < 0.01) was an independent risk factor for SSI of reduction-mastopexy surgery. The complication rate of reduction mammaplasty (1.01%) and gynecomastia correction was lower (0.75%), and there was no record of complication in mastopexy procedures (n = 161). CONCLUSION The incidence of postoperative complications following aesthetic breast surgery is low. Risk factors for complications mainly include increasing age, perioperative antibiotic use, periareolar incision, and extensive volume resection. Much more attention should be focused on those high-risk patients in clinical practice to decrease breast infection.

Abstract
BACKGROUND Prophylactic antibiotics are commonly prescribed at discharge for mastectomy, despite guidelines recommending against this practice. We investigated factors associated with postdischarge prophylactic antibiotic use after mastectomy with and without immediate reconstruction and the impact on surgical-site infection (SSI). STUDY DESIGN We studied a cohort of women aged 18-64 years undergoing mastectomy between January 1, 2010, and June 30, 2015, using the MarketScan commercial database. Patients with nonsurgical perioperative infections were excluded. Postdischarge oral antibiotics were identified from outpatient drug claims. SSI was defined using International Classification of Diseases, Ninth Edition, Clinical Modification (ICD-9-CM) diagnosis codes. Generalized linear models were used to determine factors associated with postdischarge prophylactic antibiotic use and SSI. RESULTS The cohort included 38,793 procedures; 24,818 (64%) with immediate reconstruction. Prophylactic antibiotics were prescribed after discharge after 2,688 mastectomy-only procedures (19.2%) and 17,807 mastectomies with immediate reconstruction (71.8%). The 90-day incidence of SSI was 3.5% after mastectomy only and 8.8% after mastectomy with immediate reconstruction. Antibiotics with anti-methicillin-sensitive Staphylococcus aureus (MSSA) activity were associated with decreased SSI risk after mastectomy only (adjusted relative risk [aRR], 0.74; 95% confidence interval [CI], 0.55-0.99) and mastectomy with immediate reconstruction (aRR, 0.80; 95% CI, 0.73-0.88), respectively. The numbers needed to treat to prevent 1 additional SSI were 107 and 48, respectively. CONCLUSIONS Postdischarge prophylactic antibiotics were common after mastectomy. Anti-MSSA antibiotics were associated with decreased risk of SSI for patients who had mastectomy only and those who had mastectomy with immediate reconstruction. The high numbers needed to treat suggest that potential benefits of postdischarge antibiotics should be weighed against potential harms associated with antibiotic overuse.

Abstract
PURPOSE Surgical site infections (SSI) in prosthesis-based breast reconstruction can have a significant impact on patient outcome. Despite current CDC (Centers for Disease Control and Prevention) guidelines recommending 24 hours of postoperative antibiotics, various perioperative antimicrobial regimens are reported in the literature. Consensus on the optimal duration of antibiotics remains unclear. In this study, the aim is to compare the incidence of surgical site infections following different antibiotic durations in alloplastic breast reconstruction. METHODS In this retrospective cohort study, all consecutive patients who underwent expander/implant-based breast reconstruction between January 2009 and December 2014 at a tertiary centre were included. Data on patient demographics, risk factors, operative time, choice and timing of antibiotic used before surgery, and the duration of postoperative antibiotic use were collected. The primary outcome, SSI, is defined according to CDC criteria. RESULTS A total of 507 consecutive expander/implant-based cases were included. Minimum follow-up time was 1 year. The overall infection incidence was 14% (95% CI: 11%-17%), and the rate of subsequent explantation was 8%. Of the infected cases, 80% (45/56) received 1 week of postoperative antibiotic, while 20% (11/56) had a prolonged course of antibiotics (2-3 weeks; P = .003, odds ratio [OR] = 2.9; 95% CI: 1.4-5.8). Most infections were superficial (65%). Prior history of radiation treatment was identified as a risk factor for developing surgical site infection (P = .02). CONCLUSION Overall infection rate and risk factors for infections are in keeping with current literature. Prescribing one week of postoperative antibiotic was found to be associated with a higher incidence of SSI compared to a more prolonged antibiotic regimen.

Abstract
SUMMARY The Plastic Surgeries Registry Network supported by the American Society of Plastic Surgeons (ASPS) and the Plastic Surgery Foundation offers a variety of options for procedural data and outcomes assessment and research. The Tracking Operations and Outcomes for Plastic Surgeons (TOPS) database is a registry created for and used by active members of ASPS to monitor all types of procedural outcomes. It functions as a way for individual or group practices to follow surgical outcomes and constitutes a huge research registry available to ASPS members to access for registry-based projects. The TOPS registry was launched in 2002 and has undergone several iterations and improvements over the years and now includes more than 1 million procedure records. Although ASPS member surgeons have proven valuable assets in contributing their data to the TOPS registry, fewer have leveraged the database for registry-based research. This article overviews the authors' experience using the TOPS registry for a database research project to demonstrate the process, usefulness, and accessibility of TOPS data for ASPS member surgeons to conduct registry-based research. This article pairs with the report of the authors' TOPS registry investigation related to 30-day adverse events associated with incision location for augmentation mammaplasty.

Abstract
BACKGROUND Enhanced understanding of early postoperative adverse events will improve patient counseling and preoperative risk modification to decrease complications in implant-based breast augmentation. This study seeks to evaluate the early major adverse events following cosmetic breast augmentation. METHODS A retrospective cohort analysis of the Tracking Outcomes and Operations for Plastic Surgeons database was performed to identify any women undergoing augmentation mammaplasty with an implant between 2008 and 2016. RESULTS A total of 84,296 patients were studied. Major adverse events were identified in 0.37 percent. Seroma requiring drainage was observed in 0.08 percent, hematoma requiring drainage was observed in 0.15 percent, deep wound disruption was observed in 0.09 percent, and implant loss was observed in 0.11 percent. The authors identified multiple independent predictors of major adverse events, including body mass index greater than 30 kg/m2 (relative risk, 2.05; p < 0.001), tobacco use (relative risk, 2.25; p < 0.001), and diabetes mellitus (relative risk, 1.8; p < 0.05). Use of a periareolar incision significantly increased the risk of developing an early postoperative complication (relative risk, 1.77; p < 0.001). CONCLUSIONS The findings of this study indicate an early major adverse event rate following cosmetic breast augmentation with implants of 0.37 percent. The authors identified multiple independent predictors of major adverse events, including body mass index greater than 30 kg/m2, tobacco use, and diabetes mellitus. In addition, when controlling for other factors, periareolar incision significantly increased the risk for major adverse events, when compared to an inframammary incision.

Abstract
Introduction: The management of acute wounds may be affected by malpractices leading to poor outcome, prolonged hospital stay and inappropriate use of antibiotic therapy.Areas covered: Acute wound infections are represented by surgical site and post-traumatic infections. The aim of this expert opinion is to identify a list of inadvisable actions and to provide a guide for an optimal management of acute wound infections. A literature search using Pubmed/MEDLINE database was performed. Articles pertaining to areas covered published until December 2019 were selected. We identified the most common malpractices in this setting and, using the Choosing Wisely methodology, we proposed a list of "Don'ts" for an easy use in clinical practice.Expert opinion: Malpractices may occur from the surgical prophylaxis to the discharge of patient. A prolonged surgical prophylaxis, the underestimation of signs and symptoms, the omission of source control, the inappropriate collection of wound swab, the improper use of clinical microbiology and pharmacology, the lack of hygiene measures and the delay of discharge are all factors that may lead to unfavorable outcome. A multidisciplinary approach is needed to optimally manage these patients. The "Don'ts" refer to all professional figures involved in the management of patients with acute wound infections.

Abstract
The management of postoperative pain is of critical importance for women undergoing breast reconstruction after surgical treatment for breast cancer. Mitigating postoperative pain can improve health-related quality of life, reduce health care resource utilization and costs, and minimize perioperative opiate use. Multimodal analgesia pain management strategies with nonopioid analgesics have improved the value of surgical care in patients undergoing various operations but have only recently been reported in reconstructive breast surgery. Regional anesthesia techniques, with paravertebral blocks (PVBs) and transversus abdominis plane (TAP) blocks, and enhanced recovery after surgery (ERAS) pathways have been increasingly utilized in opioid-sparing multimodal analgesia protocols for women undergoing breast reconstruction. The objectives of this review are to 1) comprehensively review regional anesthesia techniques in breast reconstruction, 2) outline important components of ERAS protocols in breast reconstruction, and 3) provide evidence-based recommendations regarding each intervention included in these protocols. The authors searched across six databases to identify relevant articles. For each perioperative intervention included in the ERAS protocols, the literature was exhaustively reviewed and evidence-based recommendations were generated using the Grading of Recommendations, Assessment, Development, and Evaluation system methodology. This study provides a comprehensive evidence-based review of interventions to optimize perioperative care and postoperative pain control in breast reconstruction. Incorporating evidence-based interventions into future ERAS protocols is essential to ensure high value care in breast reconstruction.

Abstract
OBJECTIVE Survey results suggest that prolonged administration of prophylactic antibiotics is common after mastectomy with reconstruction. We determined utilization, predictors, and outcomes of postdischarge prophylactic antibiotics after mastectomy with or without immediate breast reconstruction. DESIGN Retrospective cohort. PATIENTS Commercially insured women aged 18-64 years coded for mastectomy from January 2004 to December 2011 were included in the study. Women with a preexisting wound complication or septicemia were excluded. METHODS Predictors of prophylactic antibiotics within 5 days after discharge were identified in women with 1 year of prior insurance enrollment; relative risks (RR) were calculated using generalized estimating equations. RESULTS Overall, 12,501 mastectomy procedures were identified; immediate reconstruction was performed in 7,912 of these procedures (63.3%). Postdischarge prophylactic antibiotics were used in 4,439 procedures (56.1%) with immediate reconstruction and 1,053 procedures (22.9%) without immediate reconstruction (P.05). CONCLUSIONS Prophylactic postdischarge antibiotics are commonly prescribed after mastectomy; immediate reconstruction is the strongest predictor. Stewardship efforts in this population to limit continuation of prophylactic antibiotics after discharge are needed to limit antimicrobial resistance. Infect Control Hosp Epidemiol 2017;38:1048-1054.

Abstract
BACKGROUND Enhanced recovery following surgery can be achieved through the introduction of evidence-based perioperative maneuvers. This review aims to present a consensus for optimal perioperative management of patients undergoing breast reconstructive surgery and to provide evidence-based recommendations for an enhanced perioperative protocol. METHODS A systematic review of meta-analyses, randomized controlled trials, and large prospective cohorts was conducted for each protocol element. Smaller prospective cohorts and retrospective cohorts were considered only when higher level evidence was unavailable. The available literature was graded by an international panel of experts in breast reconstructive surgery and used to form consensus recommendations for each topic. Each recommendation was graded following a consensus discussion among the expert panel. Development of these recommendations was endorsed by the Enhanced Recovery after Surgery Society. RESULTS High-quality randomized controlled trial data in patients undergoing breast reconstruction informed some of the recommendations; however, for most items, data from lower level studies in the population of interest were considered along with extrapolated data from high-quality studies in non-breast reconstruction populations. Recommendations were developed for a total of 18 unique enhanced recovery after surgery items and are discussed in the article. Key recommendations support use of opioid-sparing perioperative medications, minimal preoperative fasting and early feeding, use of anesthetic techniques that decrease postoperative nausea and vomiting and pain, use of measures to prevent intraoperative hypothermia, and support of early mobilization after surgery. CONCLUSION Based on the best available evidence for each topic, a consensus review of optimal perioperative care for patients undergoing breast reconstruction is presented.

Abstract
Surgical site infection (SSI) after immediate breast reconstruction is much more common than would be expected after a clean surgical procedure. Although the SSI rates reported in individual studies are quite variable, there are no obvious explanations for the variation in infection rates between institutions. The microbiology of these SSIs is unusual, with higher proportions of infections caused by atypical Myobacterium species and Gram-negative bacilli than would be expected for this anatomic site. In an effort to prevent SSIs, many surgeons use a variety of different practices including irrigation and soaking of implants with antibiotic solutions and prolonged duration of prophylactic antibiotics, although the literature to support these practices is very sparse. In particular, prolonged use of antibiotics post-discharge is concerning due to the potential for harm, including increased risk of Clostridium difficile infection, development of antibiotic resistant organisms, and drug-related allergic reactions. With higher rates of mastectomy and breast implant reconstruction in women with early-stage breast cancer, including greater utilization of reconstruction in higher-risk individuals, the number of women suffering from infection after oncologic reconstruction will likely continue to increase. It is imperative that more research be done to identify modifiable factors associated with increased risk of infection. It is also essential that larger studies with rigorous study designs be performed to identify optimal strategies to decrease the risk of SSI in this vulnerable population.

Abstract
INTRODUCTION The Breast reconstruction Risk Assessment (BRA) Score estimates patient-specific risk for postsurgical complications using an individual's unique combination of preoperative variables. In this report, we externally validate the BRA Score models for surgical site infection, seroma, and explantation in a large sample of intra-institutional patients who underwent prosthetic breast reconstruction. METHODS We reviewed all initiated tissue expander/implant reconstructions by the senior authors from January 2004 to December 2015. BRA Score risk estimates were computed for each patient and compared against observed rates of complications. Hosmer-Lemeshow goodness-of-fit test, concordance statistic, and Brier score were used to assess the calibration, discrimination, and accuracy of the models, respectively. RESULTS Of the 1152 patients (1743 breasts) reviewed, 855 patients (1333 breasts) had complete data for BRA-score calculations and were included for analysis. Hosmer-Lemeshow tests for calibration demonstrated a good agreement between observed and predicted outcomes for surgical site infection (SSI) and seroma models (P-values of 0.33 and 0.16, respectively). In contrast, predicted rates of explantation deviated from observed rates (Hosmer-Lemeshow P-value of 0.04). C statistics demonstrated good discrimination for SSI, seroma, and explantation (0.73, 0.69, and 0.78, respectively). CONCLUSIONS In this external validation study, the BRA Score tissue expander/implant reconstruction models performed with generally good calibration, discrimination, and accuracy. Some weaknesses in certain models were identified as targets for future improvement. Taken together, these analyses validate the clinical utility of the BRA score risk models in predicting 30-day outcomes.
