Incidence and Risk Factors for Major Surgical Site Infections in Aesthetic Surgery: Analysis of 129,007 Patients

Cutibacterium avidum: A virulent pathogen in esthetic surgery infection, a case series

Cutibacterium avidum is a member of the skin microbiota whose composition changes with age. Recently, it has been implicated in infections associated with implants and other medical devices, and it is now recognized as an etiological agent of surgical site infections. We present six cases of surgical site infections following aesthetic surgery: three cases linked to gluteal implants, one to gluteoplasty without implants, one to liposuction and one to abdominoplasty. Previously, C. avidum was considered a contaminant; however, recent findings indicate virulence factors and pathogenic behavior, so this microbe now is regarded as a potential causative agent of infection.

Evaluation of Negative Pressure Wound Therapy dressing in the management of mommy makeover surgery wounds

Background

This investigation explores the potential impact of Negative Pressure Wound Therapy (NPWT) dressing on mommy makeover surgical wounds. The focus is on optimizing the healing process and post-surgical care to mitigate complications like wound dehiscence, seroma, and hematoma.

Patients and methods

A prospective study spanned from October 2015 to April 2022, involving 40 patients undergoing mommy makeover surgery for aesthetic purposes. The randomized division resulted in two groups. Group one (n = 20) had donor sites covered with NPWT dressing, while group two (n = 20) received standard dressings lacking known healing-promoting agents. The assessment of complications served as an index of NPWT efficacy, and scars were evaluated using the Vancouver Scale.

Results

Immediate post-surgical use of NPWT dressings significantly expedited wound healing compared to fine-mesh gauze dressings. Furthermore, it almost eradicated discomfort and pain in all patients, indicating excellent compliance. Patients tolerated NPWT well, with no instances of dressing failure or non-compliance.

Conclusion

This study underscores the utility of NPWT dressing in managing mommy makeover surgery wounds. The dressing's bio-occlusive properties create an optimal environment for wound healing, simultaneously minimizing pain, discomfort, and preventing key complications such as seroma and unfavorable scar appearance.

Is topical antibiotic use necessary to prevent surgical site infection following oculoplastic surgery?

PURPOSE

To assess whether oculoplastic surgeries can be performed without any topical and systemic antibiotics, in a "100% antibiotic free" fashion.

METHOD

We conducted a multicenter retrospective study between November 2017 and December 2022. Patients who underwent an oculoplastic procedure were screened. Patients who received preoperative or postoperative systemic antibiotics were excluded. Intraoperative IV antibiotics were allowed. Patients were divided into two groups: those who were treated with local antibiotics ointments (LATB group) and those who were treated without local antibiotics ointments (LATB free group) postoperatively. The primary outcome was the incidence of surgical site infections (SSI). The relationship between the use of local antibiotics and the occurrence of SSI was assessed using Fisher's exact test. The alpha risk was set to 5% and two-tailed tests were used.

RESULTS

Among the 947 procedures included, 617 were included in the LATB group and 330 in the LATB free group. 853 and 80 procedures were classified Altemeier class 1 (clean) and class 2 (clean-contaminated) surgeries, respectively. Overall, 310 (32.73%) procedures were performed without any systemic nor topical antibiotics (100% antibiotic free fashion). SSI occured in four (4/617; 0.65%) and five (5/330; 1.52%) procedures in the LATB and LATB free group respectively, without any statistical difference between the groups (p = 0.290). A subgroup analysis was carried out by excluding the procedures performed under prophylactic intraoperative intravenous antibiotics and did not reveal any statistical difference between the two groups (p = 0.144). All SSI patients were treated with systemic antibiotics with favorable outcomes. Postoperative wound dehiscence was the only risk factor associated with postoperative SSI (p = 0.002).

CONCLUSION

This study suggests that performing a "100% antibiotic free" oculoplastic surgery without systemic and topical antibiotics is reasonable in Altemeier class 1 and class 2 procedures.

It Is Time to Resolve the Dilemma and Move Away From Using Drains in Primary Breast Augmentation

Background

Breast augmentation is one of the most commonly performed aesthetic surgical procedures, yet there has been no consensus on the use of drains. While some surgeons believe in using them due to fear of complications or because they were taught in a conventional manner, the authors present their experience of performing breast surgery without the use of drains.

Objectives

To study whether performing breast augmentation without the use of drains is safe.

Methods

Anthropometric details and complications of all the consecutive primary breast augmentation patients performed by a single surgeon from 2009 to 2022 were collected and analyzed. In none of these patients, drains were used.

Results

A total of 429 (21%) patients were lost to follow-up and only those 1617 patients with a minimum follow-up of 6 months were included in this study. The mean age of the study group was 29.8 years with a mean BMI of 24.68. Mean follow-up was 16.24 months. Hematoma occurred in 15 patients (0.92%), seroma in 12 (0.74%), explantation due to infection in 3 patients (0.18%), and capsular contracture in 44 patients (2.72%). All these complications were in the lower range of complications of breast augmentation reported in the literature.

Conclusions

Unwarranted use of drains in breast augmentation should be avoided as it does not seemingly prevent the complications of breast augmentation surgery. Instead, it may increase the chances of infection, pain, and discomfort, and prolong the antibiotic coverage, and hence put an additional overall financial burden on the patient.

Surgical Marking Pen Contamination: Writing a Postoperative Infection Into Your Preoperative Plan

Introduction Preoperative marking is an essential safety practice to prevent "never" events, including wrong site surgery. Moreover, the Joint Commission regulations of the Universal Protocol require that patients be marked to indicate the operative site. Marking typically occurs with a pen or marker, which may be disposable or reusable. Previous studies have demonstrated that methicillin-resistant Staphylococcus aureus (MRSA) can survive in the dark, moist, capped environment of the marking pen and thus could plausibly be a nidus for transmission from patient to patient. The Joint Commission has established no increased risk of postoperative infection with these markings. With this study, we aimed to determine the colonization of surgical marking pens in the plastic surgery population. Methods Two marking pens from five different attending plastic surgeons at a single institution were cultured in standard fashion for aerobic and anaerobic growth. All pens were used repeatedly in office settings for performing patient markings. Those same ten marking pens were then used to mark incision sites on mock patients. Standard povidone-iodine prepping was then performed in a paint-only fashion over the skin markings, and cultures were again taken. A control group consisted of cultures from five sterile pens from the operating room. Each sterile pen was opened, uncapped, and then swabbed. All twenty-five cultures were analyzed in the hospital laboratory in a blinded fashion. Results The five control pens revealed no bacterial growth. Of the 10 direct pen cultures, two samples grew coagulase-negative staphylococci and one culture contained Pseudomonas aeruginosa. The 10-patient marked and prepped specimens showed eight negative cultures and two with coagulase-negative staphylococci. Although Pseudomonas was detected on standard pen culture, no pseudomonal growth was present in any of the samples after patient marking and prepping with povidone-iodine. Conclusions Our findings reaffirm that marking pens may be vehicles for bacterial transmission and expand upon previous studies by describing the presence of bacterial colonization on marking pens even after surgical site preparation with povidone-iodine.

Tracking Complications and Unplanned Healthcare Utilization in Aesthetic Surgery: An Analysis of 214,504 Patients Using the TOPS Database

BACKGROUND

Tracking surgical complications and unplanned healthcare utilization is essential to inform quality initiatives in aesthetic surgery. This study used the Tracking Operations and Outcomes for Plastic Surgeons database to characterize rates and predictors of surgical complications and unplanned healthcare utilization across common aesthetic surgery procedures.

METHODS

The Tracking Operations and Outcomes for Plastic Surgeons database was queried for all patients undergoing breast augmentation, liposuction, blepharoplasty, rhinoplasty, and abdominoplasty from 2008 to 2019. Incidence and risk factors for complications and unplanned readmission, reoperation, and emergency room visits were determined.

RESULTS

A total of 214,504 patients were identified. Overall, 94,618 breast augmentations, 56,756 liposuction procedures, 29,797 blepharoplasties, 24,946 abdominoplasties, and 8387 rhinoplasties were included. A low incidence of perioperative complications was found, including seroma (1.1%), hematoma (0.7%), superficial wound complication (0.9%), deep surgical-site infection (0.2%), need for blood transfusion (0.05%), and deep venous thrombosis/pulmonary embolism (0.1%). Incidence of unplanned readmission, emergency room visits, and reoperation were 0.34%, 0.25%, and 0.80%, respectively. Patients who underwent an abdominoplasty more commonly presented to the emergency room and had unplanned readmissions or reoperations compared with other studied procedures. Furthermore, increased age, diabetes, higher body mass index, American Society of Anesthesiologists class, longer operative times, and pursuit of combined aesthetic procedures were associated with increased risk for unplanned health care use.

CONCLUSIONS

There is a low incidence of perioperative complications and unplanned healthcare utilization following common aesthetic surgery procedures. Continued entry into large national databases in aesthetic surgery is essential for internal benchmarking and quality improvement.

Necrotizing Skin and Soft Tissue Infection after Gluteal Augmentation in a Perioperatively Asymptomatic COVID-19 Patient-Complications of the Post-Lockdown Era? A Case Report

Introduction: Aesthetic surgery procedures are generally done in a relatively healthy population and carry a rather low risk compared to other surgical specialties. The incidence of complications in aesthetic surgery varies greatly depending on the type, wound cleanliness regarding the anatomical site, complexity of the surgery, patient's age, and comorbidities but is generally considered low. The overall incidence of surgical site infections (SSIs) in all aesthetic surgical procedures is around 1% in most of the literature while cases of necrotizing soft tissue infections are mostly found as individual reports. In contrast, treating COVID-19 patients is still challenging with many diverse outcomes. Surgical stress and general anesthesia are known mediators of cellular immunity impairment while studies regarding COVID-19 infection unquestionably have shown the deterioration of adaptive immunity by SARS-CoV-2. Adding COVID-19 to the modern surgical equation raises the question of immunocompetence in surgical patients. The main question of the modern post-lockdown world is: what could be expected in the postoperative period of perioperatively asymptomatic COVID-19 patients after aesthetic surgery? Case report: Here, we present a purulent, complicated, necrotizing skin and soft tissue infection (NSTI) after gluteal augmentation most likely triggered by SARS-CoV-2-induced immunosuppression followed by progressive COVID-19 pneumonia in an otherwise healthy, young patient. To the best of our knowledge, this is the first report of such adverse events in aesthetic surgery related to COVID-19. Conclusion: Aesthetic surgery in patients during the incubation period of COVID-19 or in asymptomatic patients could pose a significant risk for surgical complications, including severe systemic infections and implant loss as well as severe pulmonary and other COVID-19-associated complications.

Prolonged postoperative antibiotic administration reduces complications after medial thigh lift

There is widespread consensus that there is no indication for postoperative antibiotic administration after elective surgery. However, medial thigh lift (MTL) remains a procedure with a notoriously high rate of wound-healing disorders and infections. This study investigates the correlation between prolonged antibiotic administration and complications after MTL in massive weight loss patients. We performed a single-institution retrospective review of 121 patients undergoing MTL between 2009 and 2020. Data on postoperative outcome, demography, surgery and comorbidities were collected. All patients received intravenous antibiotics preoperatively. One group was continued on oral antibiotics for two weeks postoperatively. Complications and surgical site infections were observed and evaluated. There was no difference between the groups regarding age, BMI, or presence of obesity-associated risk factors. We observed complications in 76 patients (71%), with 60 (56%) minor and 16 (15%) major complications. The group without prolonged antibiotic administration had a higher number of total complications (OR 3.5; p = 0.0037), major complications (OR 4; p = 0.01), and wound infections (OR 6.8; p = 0.0004). Logistical regression analysis showed that this effect was independent of type of weight loss, resection volume, and age. Reduction of major infections by prolonged antibiotics was, however, dependent on BMI Δ. No side-effects associated with antibiotics were registered in this series. This study suggests that prolonged antibiotic administration may decrease complications in MTL. We thus continue to use prolonged antibiotic administration after MTL. Further research is needed to determine the optimal duration of antibiotic treatment. Level of Evidence: Level IV: therapeutic study.

Safety of body contouring surgery in an aging patient population

The fastest-growing age group undergoing cosmetic procedures are those over age 60, i.e. the aging patient group. While advanced age is a known predictor for increased surgical complications, the effects of age on complications in specific plastic procedures have yet to be thoroughly investigated. To determine the relationship between increased age and risk of surgical complications following body contouring procedures, specifically: abdominoplasty, brachioplasty, mastopexy, bilateral reduction, and thigh lift. A retrospective analysis of all patients undergoing body contouring procedures of the categories mentioned above between 2000-2018 at a tertiary university medical center. Patients were divided into two age groups: those below and those above, age 60. Data analysis included: demographics, underlying medical conditions, procedure type, and occurrence of postoperative complications (according to the Clavien-Dindo classification system). 803 body contouring procedures were identified, with 12% performed on the aging population. Aging patients had more underlying medical conditions than the younger ones. While the distribution of procedure type was similar in both groups, mastopexy was more common in aging patients. Of the 107 procedures identified as having complications, 37 were classified as grade I, 38 as grade II, and 32 as grade III. As a categorical variable, no relationship was found between the age of the patients and an increased risk of postoperative complications (age cut-off as 60). However, as a continuous variable, increased age did increase the overall risk of postoperative complications, although no optimal age as a cut-off point was identified. In multivariant analysis, diabetes mellitus with abdominoplasty was identified as a risk factor for postoperative complications. Conclusions: When undergoing body contouring procedures, we found that patients over the age of 60 are not at increased risk for postoperative complications than those under that age. Although age as a continuous variable was found to increase the overall postoperative complications, no optimal age could be defined as a cut-off point.

Mapping of Perfusion During Full-Thickness Blepharotomy Using Laser Speckle Contrast Imaging

PURPOSE

The aim of this study was to monitor how the blood perfusion in human upper eyelids is affected during full-thickness blepharotomy.

METHODS

Seven eyelids in 5 patients with upper eyelid retraction due to Graves' disease underwent full-thickness blepharotomy. Perfusion was measured using laser speckle contrast imaging in the eyelid margin and in the conjunctival pedicle.

RESULTS

Immediately following the procedure, a nonsignificant reduction in perfusion was observed in the skin of the pretarsal eyelid margin, being 66% of the initial value ( p = n.s.). However, a statistically significant decrease in perfusion, to 53% of the initial value ( p < 0.01), was seen in the central pedicle of the conjunctiva. There were no surgical complications such as infection, signs of ischemia, or bleeding.

CONCLUSIONS

In this study, eyelid perfusion was mapped during full-thickness blepharotomy for the first time using laser speckle contrast imaging. The results showed that perfusion is sufficiently preserved during surgery, probably due to the rich vascular supply in the periocular region, which may explain the low risk of postoperative complications such as ischemia and infection.

Comparative Incidence of Periocular Surgical Site Infections with Increased Surgical Mask Use during the COVID-19 Pandemic

PURPOSE

To evaluate the effect of surgical mask use on infection rates for office-based periocular surgeries during the pandemic.

METHODS

An Institutional Review Board-approved retrospective review of medical records identified patients who had an office-based oculofacial plastic surgery procedure during the pandemic between March and December 2020. Statistical analysis was used to compare this group to patients that underwent procedures between March and December 2019, prior to the pandemic when neither surgeon nor patient wore a surgical mask.

RESULTS

The study consisted of 680 patients. Thirty-one different types of procedures were encountered. The incidence of infections in 2020 compared to 2019 was not statistically significant (1.12% (n = 3) versus 1.21% (n = 5), p = 1). All patients with infections were treated with oral antibiotics and improved without long-term complications.

CONCLUSIONS

Periocular surgical site infections are uncommon, and the wearing of surgical masks by patient and surgeon during our office-based oculofacial procedures did not change the incidence of SSIs.

A Novel Artificial Intelligence-assisted Risk Assessment Model for Preventing Complications in Esthetic Surgery

Prevention of complications to reduce morbidity and mortality, and improve patient satisfaction is of paramount importance to plastic surgeons. This study aimed to evaluate the predictive risk factors for complications and to validate a novel risk assessment model, using artificial intelligence.

METHODS

A retrospective review of esthetic surgery procedures performed by the author between 2015 and 2020 was conducted. The Pearson correlation test was used to analyze the risk factors and complications. Differences in the mean risk scores among the three risk groups were tested using one-way analysis of variance. Risk scoring was validated using a machine learning process with a support vector machine in a Google Colaboratory environment.

RESULTS

Of the 372 patients, 28 (7.5%) experienced complications. The Pearson correlation coefficients between the risk score and body mass index (BMI: 0.99), age (0.97), and Caprini score of 5 or more (0.98) were statistically significant (P < 0.01). The correlations between the risk scores and sex (-0.16, P = 0.58), smoking habit (-0.16, P = 0.58), or combined procedures (-0.16, P = 0.58) were not significant. Necrosis was significantly correlated with dehiscence (0.92, P = 0.003) and seroma (0.77, P = 0.041). The accuracy of the predictive model was 100% for the training sample and 97.3% for the test sample.

CONCLUSIONS

Body mass index, age, and the Caprini score were risk factors for complications following esthetic surgery. The proposed risk assessment system is a valid tool for improving eligibility and preventing complications.

Obesity: is it an additional risk factor in analyzing surgical outcomes in the South Indian population?

Aim

This study aims to determine whether obesity impacts surgical outcomes among patients undergoing surgery at the Surgery Unit in a tertiary care hospital.

Methods

This is a retrospective study. Data were retrieved from the medical records of patients who underwent surgery at a tertiary care hospital. Patient demographics, co-morbidities, intraoperative and postoperative pain scores and complications, if occurring, were compiled for each patient. Patients were subdivided into four subsets based on their disease profile. Each subset was divided into two groups based on their body mass index (BMI). Preoperative BMI greater than or equal to 25 kg/m² was classified as obese.

Results

The study showed that there is a considerable increase in the duration of surgery in obese when compared to non-obese. 30 days readmission rate was higher among obese in all the subsets. We find that in the subset of non-infective conditions, post operative pain mean ranking score is greater among obese (128.8 vs 109.6).

Conclusions

In conclusion, the impact of obesity resulted in increased duration of surgery and post-operative pain. The association between obesity and surgical outcome shows the importance to further research to find a way to prevention of some of the complications of surgery that could occur in patients with high BMI.

The Role of Topical Antibiotic Prophylaxis in Oculofacial Plastic Surgery: A Randomized Controlled Study

PURPOSE

The usefulness of topical antibiotic prophylaxis for routine oculofacial plastic surgery is not well established. Given concerns such as contact dermatitis, antibiotic resistance, and healthcare costs in conjunction with a low baseline rate of surgical site infections, the investigators sought to determine the frequency of infection with and without the use of topical antibiotic prophylaxis.

DESIGN

Randomized, controlled, unmasked clinical trial.

PARTICIPANTS

Adult patients undergoing routine periocular surgery without prior history of periocular surgical site infection, need for perioperative oral or parenteral antibiotics, or allergy to all study medications.

METHODS

Participants were randomized before surgery to receive either antibiotic or placebo (mineral oil and petrolatum-based) ointment after surgery. Outcomes were measured at the first postoperative visit. The 2-tailed Fisher exact test was used to compare outcomes between groups.

MAIN OUTCOME MEASURES

The primary outcome was the incidence of surgical site infections. The secondary outcomes included stratification of infections by patient risk characteristics, incidence of allergic contact dermatitis, and incidence of wound complications.

RESULTS

Four hundred one participants were enrolled and randomized, and 13 participants did not proceed with surgery or were lost to follow-up. High-risk features for infection were identified in 24% of the placebo group and 21% of the antibiotic group. Surgical site infections were more common in the placebo group (2.7% vs. 0.0%; P = 0.025). The rate of contact dermatitis was similar (0.5% vs. 0.5%; P = 1.00), as was the rate of wound dehiscence (2.7% vs. 3.5%; P = 0.77). Among the placebo group, the incidence of infections in the low- and high-risk participants was 2.9% and 2.2%, respectively. Infections were treated with oral or topical antibiotics and resolved without complication, except in 1 patient who required 2 subsequent surgeries to address the sequelae.

CONCLUSIONS

After routine oculofacial plastic surgery, patients treated with a topical antibiotic ointment showed a lower risk of surgical site infection compared with patients treated with a nonantibiotic ointment.

Necrotizing soft tissue infection after liposculpture; Case report

•

Infections in isolated liposuction procedures are reported as only 0.1 % of cases

•

One of the most serious complications of liposuction is necrotizing soft tissue infection (NSTI).

•

Rapid recognition of NSTI is life saving; with urgent extensive debridement and prophylactic antibiotics as the mainstay of treatment for this condition

Introduction

Liposculpture procedures have a complication rate of 5%, with the majority being minor complications. Infections in isolated liposuction procedures are as low as 0.1 % of cases. Necrotizing infections can occur after major traumatic injuries, as well as after minor breaches of the skin or mucosa. Here we present a case of a 53-year-old female patient who underwent cosmetic surgery and developed a necrotizing soft tissue infection and we will discuss the importance of early diagnosis, risk factors and preventive measures, treatment options and our management of this particular case.

Presentation of Case

53-year-old female patient with a history of multiple cosmetic surgeries, with no significant past medical history, she presented fever and disabling pain at the surgical site with extensive bullae formation; during her fourth post operative day, she presented septic shock that required vasopressor support and mechanical ventilation, accompanied by acute renal failure which required admission to the intensive care unit.

The patient’s relatives requested air transportation to bring the patient to our center.

The patient remained hospitalized for 42 days in which 15 surgical interventions were performed including multiple surgical wound cleansing and debridement as well as placement of a negative pressure wound therapy system, flaps advancement, lesions reconstruction, graft procurements and insertions.

Discussion

Antibiotic prophylaxis is recommended preferably with a second-generation cephalosporin, one hour prior to surgery and should be continued for 5–6 days afterwards. Likewise, prophylaxis with Flucloxacillin or gentamicin is recommended in the case of liposuction and or abdominoplasty. The microorganisms most frequently isolated in post-liposuction infections are Staphylococcus aureus, Streptococcus group A, Streptococcous pyogenes, and synergistic infections with anaerobes and facultative pathogens.

Among the most severe complications of liposuction is necrotizing soft tissue infection (NSTI), which is an infection of the subcutaneous tissue that spreads to the underlying dermis and sometimes beyond including the fascia and muscle.

Conclusion

Rapid recognition of NSTI is life-saving and urgent, extensive debridement and prophylactic antibiotics are the mainstay treatment for this condition, multiple debridement procedures may be necessary for successful treatment.

Plastic Surgery Complications: A Review for Emergency Clinicians

The number of aesthetic surgical procedures performed in the United States is increasing rapidly. Over 1.5 million surgical procedures and over three million nonsurgical procedures were performed in 2015 alone. Of these, the most common procedures included surgeries of the breast and abdominal wall, specifically implants, liposuction, and subcutaneous injections. Emergency clinicians may be tasked with the management of postoperative complications of cosmetic surgeries including postoperative infections, thromboembolic events, skin necrosis, hemorrhage, pulmonary edema, fat embolism syndrome, bowel cavity perforation, intra-abdominal injury, local seroma formation, and local anesthetic systemic toxicity. This review provides several guiding principles for management of acute complications. Understanding these complications and approach to their management is essential to optimizing patient care.

Necrotizing Soft Tissue Infection and Perforated Viscus After Suction-Assisted Lipectomy

Suction-assisted lipectomy (SAL) is a commonly performed cosmetic surgery in the United States and has been steadily increasing in popularity over the past few years. As more of these surgeries are performed, several rare but life-threatening complications are being recognized, including necrotizing soft tissue infections (NSTIs). NSTIs require rapid surgical intervention but can be challenging to diagnose, as skin manifestations may be difficult to differentiate from normal post-SAL changes. We present a case of a 44-year-old female who presented with signs of septic shock after SAL of her abdomen and back. She was ultimately found to have an NSTI of her abdominal wall, likely due to perforated viscus that occurred as a complication of her procedure. This case demonstrates the significance of recognizing NSTIs as a potential complication of SAL in ill-appearing patients with non-specific symptoms and septic shock.

Surgical Site Infection Risk Factor Analysis in Postbariatric Patients Undergoing Body Contouring Surgery: A Nested Case-Control Study

BACKGROUND

Surgical site infections (SSIs) following body-contouring plastic surgery pose a significant burden on patients and caregivers, possibly leading to undesired surgical outcomes. Surgical site infection incidence following body-contouring plastic surgery ranges from 2% to 7%, but is estimated much higher among postbariatric massive weight loss (MWL) patients.

OBJECTIVE

The aim of this study was to evaluate SSI rate, risk and protective factors among postbariatric MWL patients following body-contouring plastic surgery.

METHODS

This was a nested case-control study of MWL patients who underwent body-contouring plastic surgery at the Department of Plastic Surgery at Assaf Harofeh Medical Center, between 2007 and 2014. Data were obtained from medical records. Surgical site infection was defined according to the Centers for Disease Control and Prevention criteria. Logistic regression was conducted to assess independent risk factors for SSIs.

RESULTS

From a cohort of 172 patients, 86 were included in the study. Surgical site infection rate was 20% (n = 17). Significant SSI risk factors included lifetime maximal weight and lifetime maximal body mass index (P = 0.039 and P = 0.002, respectively), body mass index loss prior to surgery (P = 0.032), estimated blood loss during surgery (P = 0.002), and gynecomastia repair procedure (P = 0.038). Independent SSI-associated factors included thigh lift procedure (odds ratio, 4.66; 95% confidence interval, 1.13-19.28) and preoperative antimicrobial prophylaxis (odds ratio, 0.04; 95% confidence interval, 0.03-0.61).

CONCLUSIONS

Although not required by current guidelines for body-contouring plastic surgery, preoperative antimicrobial prophylaxis in our study demonstrated a significant protective effect against SSIs. Further research may reveal its true contribution to SSI prevention in body-contouring plastic surgery.

A comprehensive unit-based safety program for the reduction of surgical site infections in plastic surgery and hand surgery

OBJECTIVE

To reduce surgical site infection (SSI) incidence in plastic surgery and hand surgery.

DESIGN

Uncontrolled before-and-after study.

SETTING

Department of plastic surgery and hand surgery of a tertiary-care teaching hospital.

PATIENTS

Patients undergoing surgery between January 2016 and April 2018.

INTERVENTION

A comprehensive unit-based safety program (CUSP) consisting of a bundle of evidence-based SSI prevention strategies and a change in safety culture was fully implemented after a 14-month baseline surveillance and implementation period. SSI surveillance was performed over an intervention period of another 14 months, and differences in SSI rates between the 2 periods were calculated. Adherence with bundle components and risk factors for SSI were further evaluated in a case-cohort analysis.

RESULTS

Of 3,321 patients, 63 (1.9%) developed an SSI, 38 of 1,722 (2.2%) in the baseline group and 25 of 1,599 (1.6%) in the intervention group (P = .20). The CUSP was associated with an adjusted relative SSI risk reduction of 41% (95% confidence interval [CI], 0.4%-65%; P = .048) in multivariable analysis, whereas the need for revision surgery increased SSI risk (odds ratio [OR], 2.63; 95% CI, 1.31-5.30; P = .007). During the intervention period, the proportion of checklists completed was 62.4%, and no difference in adherence with bundle components between patients with and without SSI was observed.

CONCLUSIONS

This CUSP helped reduce SSI in a surgical specialty with a low baseline SSI incidence, even though adherence with checklist completion was moderate and the main modifiable risk factors remained unchanged over time. Programs that include safety culture change may more effectively promote SSI reduction than prevention bundles alone.

Surgical Site Infections in Aesthetic Surgery

Surgical site infections represent one of the most common postoperative complications in patients undergoing aesthetic surgery. As with other postoperative complications, the incidence of these infections may be influenced by many factors and varies depending on the specific operation performed. Understanding the risk factors for infection development is critical because careful patient selection and appropriate perioperative counseling will set the right expectations and can ultimately improve patient outcomes and satisfaction. Various perioperative prevention measures may also be employed to minimize the incidence of these infections. Once the infection occurs, prompt diagnosis will allow management of the infection and any associated complications in a timely manner to ensure patient safety, optimize the postoperative course, and avoid long-term sequelae.

Evidenced-Based Approach to Abdominoplasty Update

The following publication was compiled as an evidence-based update for plastic surgeons performing abdominoplasty from a review of the published literature on that subject between January 2014 and February 2017. It is an overview of various aspects of abdominoplasty including preoperative patient assessment, variations and advances in both surgical and anesthetic technique, patient safety, and outcomes. It is intended to serve as an adjunct to previously published evidence-based reviews of abdominoplasty.

The Effect of Smoking in the Cosmetic Surgery Population: Analysis of 129,007 Patients

Background

Smoking has been associated with several postoperative adverse outcomes across multiple surgical disciplines, but the literature is limited for aesthetic surgical procedures.

Objectives

To compare complication rates between smokers and nonsmokers undergoing common cosmetic procedures, identify specific cosmetic procedures where smoking increases the risk of complications, and evaluate smoking as an independent risk factor for major complications following aesthetic surgery.

Methods

A prospective cohort of patients undergoing cosmetic surgery between 2008 and 2013 was identified from the CosmetAssure database. Smoking was evaluated as a risk factor for major complications requiring emergency room visit, hospital admission, or reoperation within 30 days after surgery. Multivariate regression analysis was performed controlling for the effects of age, gender, body mass index, type of surgical facility, type of procedure, and combined procedures.

Results

Of the 129,007 patients, 10,621 (8.2%) were smokers. All procedures examined, except breast augmentation, were more frequently performed in the nonsmoker cohort. Overall major complications were similar between smokers and nonsmokers (2.0% vs 1.9%, P = 0.57). In univariate analysis, surgical site infections (0.6% vs 0.5%, P = 0.04) were significantly higher among smokers, but suspected venous thromboembolism (0.2% vs 0.1%, P = 0.01) was significantly higher among nonsmokers. Notably, smokers had a higher risk of major complications after body procedures (2.9% vs 1.0%, P = 0.01), as well as thigh lifts (23.8% vs 3.6%, P < 0.01) and male breast surgery (3.7% vs 1.4%, P = 0.03). In multivariate analysis, smoking was found to be an independent predictor of surgical site infections (relative risk 1.61, P < 0.01).

Conclusions

Smoking is an independent risk factor of major surgical site infections following aesthetic surgery. Body procedures, as well as thigh lifts and male breast surgery, have higher complication rates in smokers.

Electronically Available Comorbidities Should Be Used in Surgical Site Infection Risk Adjustment

Background

Healthcare-associated infections such as surgical site infections (SSIs) are used by the Centers for Medicare and Medicaid Services (CMS) as pay-for-performance metrics. Risk adjustment allows a fairer comparison of SSI rates across hospitals. Until 2016, Centers for Disease Control and Prevention (CDC) risk adjustment models for pay-for-performance SSI did not adjust for patient comorbidities. New 2016 CDC models only adjust for body mass index and diabetes.

Methods

We performed a multicenter retrospective cohort study of patients undergoing surgical procedures at 28 US hospitals. Demographic data and International Classification of Diseases, Ninth Revision codes were obtained on patients undergoing colectomy, hysterectomy, and knee and hip replacement procedures. Complex SSIs were identified by infection preventionists at each hospital using CDC criteria. Model performance was evaluated using measures of discrimination and calibration. Hospitals were ranked by SSI proportion and risk-adjusted standardized infection ratios (SIR) to assess the impact of comorbidity adjustment on public reporting.

Results

Of 45394 patients at 28 hospitals, 573 (1.3%) developed a complex SSI. A model containing procedure type, age, race, smoking, diabetes, liver disease, obesity, renal failure, and malnutrition showed good discrimination (C-statistic, 0.73) and calibration. When comparing hospital rankings by crude proportion to risk-adjusted ranks, 24 of 28 (86%) hospitals changed ranks, 16 (57%) changed by ≥2 ranks, and 4 (14%) changed by >10 ranks.

Conclusions

We developed a well-performing risk adjustment model for SSI using electronically available comorbidities. Comorbidity-based risk adjustment should be strongly considered by the CDC and CMS to adequately compare SSI rates across hospitals.

Aesthetic Surgical Procedures in Men: Major Complications and Associated Risk Factors

BACKGROUND

The number of men undergoing cosmetic surgery is increasing in North America.

OBJECTIVES

To determine the incidence and risk factors of major complications in males undergoing cosmetic surgery, compare the complication profiles between men and women, and identify specific procedures that are associated with higher risk of complications in males.

METHODS

A prospective cohort of patients undergoing cosmetic surgery between 2008 and 2013 was identified from the CosmetAssure database. Gender specific procedures were excluded. Primary outcome was occurrence of a major complication in males requiring emergency room visit, hospital admission, or reoperation within 30 days of the index operation. Univariate and multivariate analysis evaluated potential risk factors for major complications including age, body mass index (BMI), smoking, diabetes, type of surgical facility, type of procedure, and combined procedures.

RESULTS

Of the 129,007 patients, 54,927 underwent gender nonspecific procedures, of which 5801 (10.6%) were males. Women showed a higher mean age (46.4 ± 14.1 vs 45.2 ± 16.7 years, P < 0.01). Men had a higher BMI (27.2 ± 4.7 vs 25.7 ± 4.9 kg/m2, P < 0.01), and were more likely to be smokers (7.1% vs 5.7%, P < 0.01) when compared to women. Men demonstrated similar overall major complication rates compared to women (2.1% vs 2.1%, P = 0.97). When specific complications were analyzed further, men had higher hematoma rates, but lower incidence of surgical site infection. Additionally, major complications after abdominoplasty, facelift surgery, and buttock augmentation were noted to preferentially affect males. On multivariate analysis, independent predictors of major complications in males included BMI (RR 1.05), hospital or ambulatory surgery center procedures (RR 3.47), and combined procedures (RR 2.56).

CONCLUSIONS

Aesthetic surgery in men is safe with low major complication rates. Modifiable predictors of complications included BMI and combined procedures.

Surgical Site Irrigation in Plastic Surgery

BACKGROUND

The incidence of infection following breast implant reconstruction remains high at the level of 24%. Surgical site irrigation is commonly used for its prevention. However, the lack of evidence-based guidelines for antibiotic prophylaxis in breast implant surgery necessitates research for optimal irrigation technique.

OBJECTIVES

composition and exposure time of irrigation solution for surgical site infection (SSI) prophylaxis using an in vitro model of a surgical site.

METHODS

The study design was an in vitro model to assess antibiotic irrigation of a surgical site. Strains of Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus, Group A Streptococcus, and Pseudomonas aeruginosa were seeded on blood agar growth medium and irrigated with various antibiotic and antiseptic solutions under different exposure times. The presence and quantity of the colonies grown were estimated after 24-hour incubation. Repetition of the studies for 5 times with each investigated irrigation solution and microorganism was performed. Optimal irrigation agents were chosen based on the ability to achieve sterility with minimal tissue toxicity.

RESULTS

The optimal wound irrigation agents for SSI prophylaxis in our study were found to be 0.05% chlorhexidine or triple antibiotic antibiotic solutions. Adding of vancomycin to the irrigation solutions did not show an increase in their effectiveness. Prolonged irrigation exposure time was necessary to achieve sterility of the in vitro model of a surgical site.

CONCLUSIONS

We recommend 0.05% chlorhexidine or triple antibiotic solution for topical SSI prophylaxis in breast implant surgery. Sufficient time of irrigation can be achieved by maintaining some of the solution in the pocket and delaying drainage for at least 30 minutes.

Incidence and Risk Factors for Major Hematomas in Aesthetic Surgery: Analysis of 129,007 Patients

BACKGROUND

Postoperative hematomas are one of the most frequent complications following aesthetic surgery. Identifying risk factors for hematoma has been limited by underpowered studies from single institution experiences.

OBJECTIVES

To examine the incidence and identify independent risk factors for postoperative hematomas following cosmetic surgery utilizing a prospective, multicenter database.

METHODS

A prospectively enrolled cohort of patients who underwent aesthetic surgery between 2008 and 2013 was identified from the CosmetAssure database. Primary outcome was occurrence of major hematomas requiring emergency room visit, hospital admission, or reoperation within 30 days of the index operation. Univariate and multivariate analysis was used to identify potential risk factors for hematomas including age, gender, body mass index (BMI), smoking, diabetes, type of surgical facility, procedure by body region, and combined procedures.

RESULTS

Of 129,007 patients, 1180 (0.91%) had a major hematoma. Mean age (42.0 ± 13.0 years vs 40.9 ± 13.9 years, P < 0.01) and BMI (24.5 ± 5.0 kg/m2 vs 24.3 ± 4.6 kg/m2, P < 0.01) were higher in patients with hematomas. Males suffered more hematomas than females (1.4% vs 0.9%, P < 0.01). Hematoma rates were higher in patients undergoing combined procedures compared to single procedures (1.1% vs 0.8%, P < 0.01), and breast procedures compared to body/extremity or face procedures (1.0% vs 0.8% vs 0.7%, P < 0.01). On multivariate analysis, independent predictors of hematoma included age (Relative Risk [RR] 1.01), male gender (RR 1.98), the procedure being performed in a hospital setting rather than an office-based setting (RR 1.68), combined procedures (RR 1.35), and breast procedures rather than the body/extremity and face procedures (RR 1.81).

CONCLUSIONS

Major hematoma is the most common complication following aesthetic surgery. Male patients and those undergoing breast or combined procedures have a significantly higher risk of developing hematomas.

Rates and Predictors of Readmission Following Body Contouring Procedures: An Analysis of 5100 Patients From The National Surgical Quality Improvement Program Database

BACKGROUND

Hospital readmissions can be a major contributor to increased healthcare costs and are a salient current topic in healthcare. There is a paucity of large, prospective studies that evaluate rates and risk factors of readmission within the aesthetic subset of plastic surgery.

OBJECTIVES

The authors propose to determine the rates of unplanned readmission following body contouring procedures and to analyze the predictors associated with it.

METHODS

The 2011 and 2012 National Surgical Quality Improvement Program Database was queried for body contouring procedures using the appropriate Current Procedural Terminology codes. The rate of unplanned readmission, preoperative risk factors, comorbidities, and medical and surgical postoperative complications data were analyzed using multivariate regression models to determine predictors of readmission after these procedures.

RESULTS

We identified 5100 patients who underwent body contouring procedures, of which 142 (2.8%) experienced an unplanned readmission. Forty-eight per cent of readmitted patients experienced at least one surgical complication, and 23.9% experienced at least one medical complication. Multivariate regression analyses identified several independent predictors of unplanned readmission: increasing age (odds ratio [OR] 1.018 per year, P = 0.039), bleeding disorders (OR 3.674, P = 0.039), increased operative time (each additional hour conferring a 20% increased risk), surgical complications (OR 19.179, P < 0.001), and medical complications (OR 10.240, P < 0.001).

CONCLUSIONS

The unplanned readmission rate for body contouring procedures is low overall (2.8%). We identified age, bleeding disorders, operative duration, and postoperative complication as independent risk factors for unplanned readmission. These data can help guide preoperative risk stratification and future interventions in high-risk patient populations.
