RESUMO

BACKGROUND: Eyelid surgeries are common operations performed for both cosmetic and functional purposes. Because the periorbital region is highly visible, it is important to avoid poor scar formation in this cosmetically sensitive region. No study to date has investigated the possible existence of keloid formation following eyelid procedures. OBJECTIVES: This study systematically reviewed the literature to identify cases of hypertrophic scar and keloid formation following cosmetic or functional (nonburn) eyelid procedures to aid surgeons when counseling patients. METHODS: A PubMed/MEDLINE search was conducted on May 17, 2022, using appropriate search terms: "blepharoplasty," "tarsorrhaphy," "canthotomy," "ptosis repair," "epicanthoplasty," "keloid," "hypertrophic scar," and related lay terms. All eligible articles in English with no lower date limit were included for analysis. Descriptive statistics, exclusion criteria, and summarized results are reported. RESULTS: The PubMed search yielded 107 abstracts/articles. Full-text review resulted in 34 articles included for analysis. Twenty manuscripts reported no occurrences of hypertrophic scars. Only 13 manuscripts reported patients with hypertrophic scarring, which equated to 36 patients out of 3650. One individual was identified in a series of 77 patients who developed a keloid after a tarsorrhaphy. No articles reported a keloid as an outcome of strictly cosmetic procedures. CONCLUSIONS: This study concludes that there are no reported instances of keloid formation following cosmetic (nonburn) eyelid procedures in the existing literature. Hypertrophic scar formation is minimally reported. The absence of keloid scar formation on the eyelid is critical knowledge for surgeons when educating patients about maladaptive scarring risks following eyelid procedures.

RESUMO

Fat grafting can restore facial volume for reconstructive and cosmetic indications. Common practice often involves extracting lipoaspirate from the most abundant anatomic location. However, grafted fat retains the phenotypic characteristics of its original location and can undergo exaggerated hypertrophy with patient weight fluctuations. The aim of this study was to systematically assess the literature to summarize the reported effects of postoperative weight gain on facial hypertrophy in patients after facial fat grafting and to determine potentially avoidable factors. A search through PubMed/MEDLINE was conducted on October 4, 2022, to identify relevant articles with appropriate search terms. No lower date limit was applied and all eligible nonanimal clinical articles in English were included for review. Reports were summarized and presented as descriptive statistics. The search generated 714 articles. After abstract and full-text review of the initial set of articles, 6 were included in our analysis. All articles described poor cosmetic outcomes resulting from nonanatomic hypertrophy of the grafted fat. None of the articles reported a thorough methodology for selecting the donor site to minimize fat hypertrophy with potential future weight fluctuations. Grafted facial fat is susceptible to exaggerated hypertrophy as a result of changes in patient weight. Specifically, harvesting lipoaspirate from maximally abundant areas of the body may increase this risk. Individualizing the area of fat donation may attenuate unwanted fat growth and further contribute to increased patient quality of life.

RESUMO

Decreased levels of Faecalibacterium prausnitzii (F. prausnitzii), whose supernatant plays an anti-inflammatory effect, are frequently found in inflammatory bowel disease (IBD) patients. However, the anti-inflammatory products in F. prausnitzii supernatant and the mechanism have not been fully investigated. Here we found that F. prausnitzii and F. prausnitzii-derived butyrate were decreased in the intestines of IBD patients. Supplementation with F. prausnitzii supernatant and butyrate could ameliorate colitis in an animal model. Butyrate, but not other substances produced by F. prausnitzii, exerted an anti-inflammatory effect by inhibiting the differentiation of T helper 17 (Th17) cells. The mechanism underlying the anti-inflammatory effects of the butyrate produced by F. prausnitzii involved the enhancement of the acetylation-promoted degradation of c-Myc through histone deacetylase 3 (HDAC3) inhibition. In conclusion, F. prausnitzii produced butyrate to decrease Th17 differentiation and attenuate colitis through inhibiting HDAC3 and c-Myc-related metabolism in T cells. The use of F. prausnitzii may be an effective new approach to decrease the level of Th17 cells in the treatment of inflammatory diseases.

RESUMO

BACKGROUND: Machine learning represents a new frontier in surgical innovation. The ranking Convolutional Neural Network (CNN) is a novel machine learning algorithm that helps elucidate patterns and features of aging that are not always appreciable with the human eye. OBJECTIVES: The authors sought to determine the impact of aesthetic rhinoplasty on facial aging employing a multidimensional facial recognition and comparison software. METHODS: A retrospective chart review and subsequent analysis was carried out on all female patients who underwent open rhinoplasty with the senior author from 2014 through 2018 and had postoperative photos at 12 or more weeks follow-up. All photos were analyzed with Microsoft Azure Face API (Redmond, WA), which estimates patients' age by cropping the face from a photograph and then extracting a CNN-based prediction through multiple deep neural networks. RESULTS: A total of 100 patients ultimately met full inclusion criteria. The average post-surgical follow up for this cohort was 29 weeks (median, 14 weeks; range, 12-64 weeks). Patients ranged from 16 to 72 years old (mean, 32.75 years; median, 28.00 years; standard deviation, 12.79 years). The ranking CNN algorithm on average estimated patients preoperatively to be 0.03 years older than their actual age. The correlation coefficient between actual age and predicted preoperative age was r = 0.91. On average, patients were found to look younger post-open rhinoplasty (-3.10 vs 0.03 years, P < 0.0001). CONCLUSIONS: The ranking CNN algorithm is both accurate and precise in estimating human age before and after cosmetic rhinoplasty. Given the resulting data, the effects of open rhinoplasty on reversing signs of facial aging should be revisited.

RESUMO

BACKGROUND: Social media use has become a relevant tool in plastic surgery. These platforms are utilized for many reasons, such as business promotion. Although beneficial, social media can cause ethical dilemmas if used incorrectly. OBJECTIVES: A review of the literature revealed what is understood about the implications of social media in regards to sponsorship/promotion. This paper aimed to create the foundation surrounding this topic and help facilitate future discussions on this new ethical dilemma. METHODS: A MEDLINE search with a custom publication date range and a review of the literature was conducted on June 15, 2019. RESULTS: The search yielded 139 articles and abstracts. After review, 26 publications were chosen for analysis. Articles were taken from the following journals: Plastic and Reconstructive Surgery (n = 12), Aesthetic Surgery Journal (n = 8), PRS Global Open (n = 2), Annals of Plastic Surgery (n = 1), BMJ (n = 1), AMA Journal of Ethics (n = 1), and Facial Plastic Surgery (n = 1). The 4 principles of medical ethics were analyzed in respect to promotion and sponsorship in plastic surgery. CONCLUSIONS: Social media is a novel platform that is becoming increasingly utilized in plastic surgery. Although its impact can be beneficial, it is not well understood in the context of social media sponsorship and promotion. To date, no peer-reviewed articles specifically discuss these limitations. It is critical that all plastic surgeons be cognizant of both the positive and negative aspects of social media before integrating it into their professional lives.

RESUMO

BACKGROUND: Cancer cells avidly consume glucose and convert it to lactate, resulting in a low pyruvate level. This phenomenon is known as the Warburg effect, and is important for cell proliferation. Although cMyc has often been described as an oncoprotein that preferentially contributes to the Warburg effect and tumor proliferation, mechanisms of action remain unclear. Histone deacetylase 3 (HDAC3) regulates gene expression by removing acetyl groups from lysine residues, as well as has an oncogenic role in apoptosis and contributes to the proliferation of many cancer cells including cholangiocarcinoma (CCA). HDAC inhibitors display antitumor activity in many cancer cell lines. Cancer cells maintain low levels of pyruvate to prevent inhibition of HDAC but the mechanisms remain elusive. The purpose of our study was to explore the role of cMyc in regulating pyruvate metabolism, as well as to investigate whether the inhibitory effect of pyruvate on HDAC3 could hold promise in the treatment of cancer cells. METHODS: We studied pyruvate levels in CCA cell lines using metabolite analysis, and analyzed the relationship of pyruvate levels and cell proliferation with cell viability analysis. We cultivated CCA cell lines with high or low levels of pyruvate, and then analyzed the protein levels of HDAC3 and apoptotic markers via Western Blotting. We then explored the reasons of low levels of pyruvate by using seahorse analysis and 13C6 metabolites tracing analysis, and then confirmed the results using patient tissue protein samples through Western Blotting. Bioinformatics analysis and transfection assay were used to confirm the upstream target of the low levels of pyruvate status in CCA. The regulation of cMyc by HDAC3 was studied through immunoprecipitation and Western Blotting. RESULTS: We confirmed downregulated pyruvate levels in CCA, and defined that high pyruvate levels correlated with reduced cell proliferation levels. Downregulated pyruvate levels decreased the inhibition to HDAC3 and consequently protected CCA cells from apoptosis. Synergistically upregulated LDHA, PKM2 levels resulted in low levels of pyruvate, as well as poor patient survival. We also found that low levels of pyruvate contributed to proliferation of CCA cells and confirmed that the upstream target is cMyc. Conversely, high activity of HDAC3 stabilized cMyc protein by preferential deacetylating cMyc at K323 site, which further contributed to the low pyruvate levels. Finally, this creates a positive feedback loop that maintained the low levels of pyruvate and promoted CCA proliferation. CONCLUSIONS: Collectively, our findings identify a role for promoting the low pyruvate levels regulated by c-Myc, and its dynamic acetylation in cancer cell proliferation. These targets, as markers for predicting tumor proliferation in patients undergoing clinical treatments, could pave the way towards personalized therapies.

RESUMO

BACKGROUND: Patients increasingly rely on online resources to make healthcare decisions. Google dominates the search engine market; first-page results receive most of the web traffic and therefore serve as an important indicator of consumer reach. OBJECTIVES: Our objective was to analyze the respective importance of physician academic pedigree, experience, and social media presence on plastic surgeon Google first-page search result placement. METHODS: A Google.com search was conducted in the top 25 United States metropolitan areas to identify the top 20 websites of board-certified plastic surgeons. Social media presence was quantified by tracking the number of followers on Facebook, Twitter, and Instagram for every surgeon as well as medical school and year of graduation. The primary outcome was website ranking in the first page of Google search results. To identify the independent predictors of presence on the front page, we performed a multivariate logistic regression. RESULTS: Total number of social medial followers was associated with Google front-page placement (P < 0.001), whereas medical school ranking and years in practice were not (P = 0.17 and 0.39, respectively). A total 19.6% of plastic surgeon practices in our study cohort still had no social media accounts whatsoever. CONCLUSIONS: For the past few decades, plastic surgery practices relied on referrals, word of mouth, and the surgeon's reputation and academic pedigree to attract new patients. It is now clear that this practice-building model is being rapidly supplanted by a new paradigm based on social media presence to reach potential patients.

RESUMO

BACKGROUND: Increased surgical duration can impact patient outcomes and operative efficiency metrics. In particular, there are studies suggesting that increased surgical duration can increase the risk of venous thromboembolism (VTE). One of the longer duration plastic surgery procedures commonly performed is microsurgical breast reconstruction. With the widening indications for multiple and "stacked" free flaps to reconstruct breasts, we endeavored to assess (1) the relationship between duration of microsurgical breast reconstruction and VTE; and (2) determine if a threshold operative time exists that connotes VTE higher risk. METHODS: Patients from the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) between 2005 and 2014 who underwent microsurgical breast reconstruction were identified by Current Procedural Terminology code. Three models of multivariate logistic regression were used to characterize the adjusted risk for VTE by operative duration, bilaterality, the length of stay, and patient demographics. RESULTS: A total of 4,782 patients who underwent microsurgical breast reconstruction were identified. Overall VTE incidence was 1.13%. The mean operative duration was 8:31 hours:minutes (standard deviation: 2:59). Operative duration was statistically associated with VTE in continuous, quintile, and dichotomized risk models. Beyond an operative duration of 11 hours, adjusted VTE risk increases fourfold corresponding to a number needed to harm of 45.8. CONCLUSIONS: Increasing surgical duration heightens the risk of VTE in microsurgical breast reconstruction. Increasing body mass index and age enhances this VTE risk. Moreover, limiting surgical duration to 11 hours or less can decrease VTE risk by fourfold vis-à-vis baseline. LEVEL OF EVIDENCE: Risk, II.

RESUMO

BACKGROUND: Recent data suggest patients are seeking aesthetic surgery to improve their appearance on Instagram and other social media. Despite the rising influence of Instagram in plastic surgery, few academic publications address Instagram, let alone evaluate its utilization in plastic surgery. OBJECTIVES: We set out to answer the following three questions: 1) what plastic surgery-related content is being posted to Instagram; 2) who is posting this content; and 3) what specific hashtags are they using? METHODS: Our study queried 21 Instagram plastic surgery-related hashtags. Content analysis was used to qualitatively evaluate each of the nine "top" posts associated with each hashtag (189 posts). Duplicate posts and those not relevant to plastic surgery were excluded. RESULTS: A total of 1,789,270 posts utilized the 21 hashtags sampled in this study. Of the top 189 posts for these 21 queried hashtags, 163 posts met inclusion criteria. Plastic surgeons eligible for membership in American Society for Aesthetic Plastic Surgery (ASAPS) accounted for only 17.8% of top posts, whereas noneligible physicians accounted for 26.4%. All nonplastic surgery trained physicians marketed themselves as "cosmetic surgeons." Nine top posts (5.5%) were by nonphysicians, including dentists, spas with no associated physician, and a hair salon. The majority of these posts were self-promotional (67.1%) as opposed to educational (32.9%). Board-certified plastic surgeons were significantly more likely to post educational content to Instagram as compared to nonplastic surgeons (62.1% vs 38.1%, P = 0.02). CONCLUSIONS: ASAPS eligible board-certified plastic surgeons are underrepresented amongst physicians posting top plastic surgery-related content to Instagram.

RESUMO

BACKGROUND: While recent studies have reported modest to no difference in breast aesthetics for shaped and round implant types in breast augmentations, the anatomy and biomechanics in the setting of breast reconstruction is different. OBJECTIVES: Accordingly, we endeavored to evaluate whether two implant types impacted nipple position and aesthetic features in prosthetic breast reconstruction. METHODS: A retrospective chart review was carried out on patients who underwent nipple-sparing mastectomy (NSM) with immediate tissue expander breast reconstruction. Patients were divided into two cohorts: smooth round implants and textured shaped implants. Postoperative photographs were evaluated to assess nipple displacement vis-à-vis a vector of maximal projection and aesthetic outcome for features of breast shape. RESULTS: Of 102 breasts meeting the inclusion criteria, 41 had tissue expander-implant reconstruction with anatomical shaped implants, and 61 had reconstruction with smooth round implants. The shaped implant cohort had less nipple deviation from the point of maximal projection (3.69 ± 6.24 vs 7.52 ± 10.50; P < 0.0001). Graded semi-quantitative aesthetic scores were also higher (4.04 ± 0.67 vs 3.72 ± 0.93; P = 0.0044) in the shaped implants than in the round cohort. CONCLUSIONS: Unlike breast augmentation, there is a paucity of overlying breast tissue and larger dissected spaces in prosthetic breast reconstruction. Our analysis suggests that in this setting, textured anatomic implants result in less nipple deviation from the point of maximum projection and improved aesthetic outcomes compared to round implants. When considering implant choice in NSM reconstruction, the manifold risks of shaped textured implants must thus be informed by potential aesthetic benefits with respect to shape and enhanced nipple sensation.

RESUMO

The National Foundation for Infantile Paralysis (NFIP), the March of Dimes, and the Georgia Warm Springs Resort were reflections of Franklin D. Roosevelt's (FDR) complicated and personal relationship with polio. Between 1934 and 1957, significant advances were made in the care of polio survivors, and new and innovative medical fields gained both public attention and funding. The plight of disabled Americans and questions of accessibility also received widespread national attention. The NFIP helped establish a new prototype for grassroots philanthropy and personified FDR's vision for national health insurance. Drawing upon a variety of archival and primary sources, this article aims to revisit Roosevelt's contribution to the medical field. Rather than condone or defend FDR's public persona as a survivor of polio, this article argues that Roosevelt and his affiliated organizations played an important medical role during this period.

RESUMO

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. LEVEL OF EVIDENCE: 2.

RESUMO

BACKGROUND: Butyrate is an energy source for colonocytes that is formed by bacterial fermentation of dietary fiber in the colon and that exerts broad anti-inflammatory activities. Although the administration of butyrate improves homeostasis in patients and ameliorates IBD (Inflammatory Bowel Disease)-related lesions and symptoms, the anti-inflammatory mechanisms of butyrate still remain unclear. To explore the impact of butyrate on Treg (Regulatory T cell)/Th17 (T helper 17 cell) differentiation and colitis in rats. METHODS: The effect of butyrate on the expression of markers related to both Tregs and Th17 cells were determined in human monocytes as well as a rat model of colitis induced by 2,4,6-trinitrobenzene sulfonic acid. Rats were treated with butyrate in vivo, whereas the rat splenocytes and human monocytes were treated in vitro. RESULTS: We found that butyrate administration increased peripheral blood Treg cell levels as well as plasma levels of anti-Th17 cytokines (IL-10 and IL-12). Butyrate administration further suppressed IL-17 levels in both plasma and colonic mucosa, and ameliorated colonic colitis lesions in rats. This promotion of Treg activity and inhibition of IL-17 release was also observed in human venous monocytes and rat splenocytes in vitro. CONCLUSIONS: Our results suggest that butyrate plays a key role in regulating the Treg/Th17 balance and ultimately protects the colon mucosa against the development of IBD.

RESUMO

BACKGROUND: Gluteal augmentation is used to improve the size and shape of the buttocks. Unlike other anatomical areas, such as the breasts, where there are classification systems for size and projection, no standardized methods for classifying gluteal size and shape exist. Patients seeking augmentation rely on photographs to communicate their desired result to surgeons. The authors' study objectively reviews this topic and proposes a novel classification system for the buttocks that can provide an organized framework for patients and providers. METHODS: A systematic of the literature was conducted on March 17, 2021, using various combinations of the following terms: "gluteal augmentation," "classification," "size," "gluteoplasty," and "Brazilian butt lift." All eligible articles were included for analysis. RESULTS: The PubMed/MEDLINE searches yielded 49 articles and abstracts. After review, eight publications were chosen for analysis. All publications were found in plastic surgery journals, with the most common journals as follows: Aesthetic Surgery Journal ( n = 4), Clinics in Plastic Surgery ( n = 2), Annals of Plastic Surgery ( n = 1), and Plastic and Reconstructive Surgery ( n = 1). There are no articles in the plastic surgery literature that provide a standardized classification system for gluteal size determination. CONCLUSIONS: The authors' study revealed the need for a standardized classification system for gluteal size and shape. Although the publications analyzed discussed various techniques for related procedures and provided ways to improve aesthetic outcomes, none presented a system for reproducibly classifying size and shape. By introducing a classification system, we hope to enable plastic surgeons to more accurately and efficiently discuss their patient's goals.

RESUMO

BACKGROUND: The popularity of social media continues to have a significant impact in the plastic surgery industry. Understanding the influence of such platforms and recognizing trends, specifically on Instagram, can reveal significant implications for education and marketing. OBJECTIVES: This study aims to gather updated information on 3 main questions: (1) what plastic surgery-related content is being posted to Instagram; (2) who is posting this content; and (3) what specific hashtags are they using? METHODS: This study analyzed 22 plastic surgery-related hashtags on Instagram. Content analysis was then used to qualitatively evaluate each of the 9 "top" posts associated with each hashtag (198). Any duplicates or posts not relevant to plastic surgery were excluded. RESULTS: A total of 11,516,969 posts utilized the 22 hashtags sampled. Of the top 198 posts, only 168 met final inclusion criteria (after duplicates and posts irrelevant to plastic surgery were excluded). Plastic surgeons eligible for membership in The Aesthetic Society accounted for only 4.17% of top posts (7 posts), whereas non-eligible physicians accounted for 20.8% (35 posts). Twenty-eight surgeons accounted for the top posts (excluding foreign surgeons); however, only 6 were board certified by either the American Board of Plastic Surgeons or The Royal College of Physicians and Surgeons of Canada. CONCLUSIONS: The Aesthetic Society eligible board-certified plastic surgeons are a minority amongst physicians posting top plastic surgery-related content on Instagram.

RESUMO

BACKGROUND: Coronavirus disease 2019 (COVID-19), known as the "coronavirus," has spread to over 170 countries. In response, many organizations have spoken out and called for cancellation of all elective surgical procedures. This study aimed to provide clear recommendations for plastic surgeons to follow by addressing the following issues: (1) What defines elective surgery, and where does one draw the line between essential versus nonessential services? (2) How does this differ in the hospital versus private practice setting? (3) If called on to operate on a patient with COVID-19, how do plastic surgeons protect themselves and still provide excellent medical care? METHODS: A Preferred Reporting Items for Systematic Reviews and Meta-Analyses systematic review of the literature on plastic surgery in the setting of a pandemic was performed on March 19, 2020. An ethical analysis was conducted using the four principles of medical ethics. RESULTS: The initial search yielded 118 articles. Eighteen articles were relevant and included for analysis. Only one editorial article was published in a plastic surgery journal. Accordingly, no peer-reviewed published COVID-19 guidelines exist for plastic surgery. Given that this pandemic may place health care systems under undue stress with an unpredictable trajectory, it is the responsibility of the plastic surgeon to assess and postpone cases whenever possible to properly contribute to adequate resource allocation and patient safety measures. CONCLUSIONS: This article fills an important gap in the literature by addressing COVID-19 and providing guidelines for upholding ethics and responsible resource allocation. By upholding these standards, plastic surgeons can do their part to help minimize the spread of this virus.

RESUMO

Critically ill patients with requirement of continuous renal replacement therapy (CRRT) represent a growing intensive care unit (ICU) population. Optimal CRRT delivery demands continuous communication between stakeholders, iterative adjustment of therapy, and quality assurance systems. This Quality Improvement (QI) study reports the development, implementation and outcomes of a quality assurance system to support the provision of CRRT in the ICU. This study was carried out at the University of Kentucky Medical Center between September 2016 and June 2019. We implemented a quality assurance system using a step-wise approach based on the (a) assembly of a multidisciplinary team, (b) standardization of the CRRT protocol, (c) creation of electronic CRRT flowsheets, (d) selection, monitoring and reporting of quality metrics of CRRT deliverables, and (e) enhancement of education. We examined 34-month data comprising 1185 adult patients on CRRT (~ 7420 patient-days of CRRT) and tracked selected QI outcomes/metrics of CRRT delivery. As a result of the QI interventions, we increased the number of multidisciplinary experts in the CRRT team and ensured a continuum of education to health care professionals. We maximized to 100% the use of continuous veno-venous hemodiafiltration and doubled the percentage of patients using regional citrate anticoagulation. The delivered CRRT effluent dose (~ 30 ml/kg/h) and the delivered/prescribed effluent dose ratio (~ 0.89) remained stable within the study period. The average filter life increased from 26 to 31 h (p = 0.020), reducing the mean utilization of filters per patient from 3.56 to 2.67 (p = 0.054) despite similar CRRT duration and mortality rates. The number of CRRT access alarms per treatment day was reduced by 43%. The improvement in filter utilization translated into ~ 20,000 USD gross savings in filter cost per 100-patient receiving CRRT. We satisfactorily developed and implemented a quality assurance system for the provision of CRRT in the ICU that enabled sustainable tracking of CRRT deliverables and reduced filter resource utilization at our institution.

RESUMO

BACKGROUND: Online reviews increasingly influence patients' decision-making. This is the first systematic, quantitative analysis of online reviews for abdominoplasty. METHODS: Reviews for abdominoplasty were sampled from RealSelf, Yelp, and Google for six major metropolitan areas. A standard social sciences framework known as grounded theory was used to evaluate factors affecting satisfaction. The relative importance of factors was quantified using odds ratios. RESULTS: Seven hundred ninety-four reviews met inclusion criteria. There was significant geographic variation with respect to number of reviews (p < 0.01) and average rating (p = 0.014). The authors identified 10 statistically significant themes affecting satisfaction. Of these, aesthetic outcome was the most mentioned theme [n = 368 (46.3 percent)] and the most dominant driver of satisfaction. Interactions with staff had the second highest odds ratio, driven by the fact that all negative staff interactions led to negative reviews. Postoperative care had the next highest odds ratio, and was demonstrated to counteract the negative effects of poor surgical outcomes on satisfaction. The occurrence of a surgical complication and the cost of surgery were least associated with satisfaction. CONCLUSIONS: This analysis is the first to use quantitative methods to identify dominant and nondominant factors affecting patient satisfaction in cosmetic surgery. The authors found that aesthetic outcome, staff interactions, and postoperative diligence were the most critical factors affecting satisfaction in abdominoplasty, whereas postoperative complications and cost were least important. Understanding the relative importance of factors may help to improve and protect one's online reputation.
