RESUMO

INTRODUCTION: The quality and readability of online health information are sometimes suboptimal, reducing their usefulness to patients. Manual evaluation of online medical information is time-consuming and error-prone. This study automates content analysis and readability improvement of private-practice plastic surgery webpages using ChatGPT. METHODS: The first 70 Google search results of "breast implant size factors" and "breast implant size decision" were screened. ChatGPT 3.5 and 4.0 were utilized with two prompts (1: general, 2: specific) to automate content analysis and rewrite webpages with improved readability. ChatGPT content analysis outputs were classified as hallucination (false positive), accurate (true positive or true negative), or omission (false negative) using human-rated scores as a benchmark. Six readability metric scores of original and revised webpage texts were compared. RESULTS: Seventy-five webpages were included. Significant improvements were achieved from baseline in six readability metric scores using a specific-instruction prompt with ChatGPT 3.5 (all P ≤ 0.05). No further improvements in readability scores were achieved with ChatGPT 4.0. Rates of hallucination, accuracy, and omission in ChatGPT content scoring varied widely between decision-making factors. Compared to ChatGPT 3.5, average accuracy rates increased while omission rates decreased with ChatGPT 4.0 content analysis output. CONCLUSIONS: ChatGPT offers an innovative approach to enhancing the quality of online medical information and expanding the capabilities of plastic surgery research and practice. Automation of content analysis is limited by ChatGPT 3.5's high omission rates and ChatGPT 4.0's high hallucination rates. Our results also underscore the importance of iterative prompt design to optimize ChatGPT performance in research tasks.

RESUMO

BACKGROUND: Medical students who attend institutions without plastic surgery residency programs are at a disadvantage in the plastic surgery match. We developed an educational program for medical students without home programs called Explore Plastic Surgery to provide an overview of the steps toward a career in plastic surgery. The purpose of this study was to assess the impact, utility, and success of the novel program. METHODS: Pre- and postevent surveys were distributed to participants. Survey data were analyzed including participant demographics, perceptions of barriers unique to those without home programs, and the overall event utility. RESULTS: Two hundred seventeen students registered for the program. Ninety-five participants completed the pre-event survey (44%), and of those, 57 participants completed the post-event survey (60%). There was an increase in understanding of the steps toward a career in plastic surgery ( P < 0.001), confidence in overcoming barriers ( P = 0.005), and level of comfort in reaching out to faculty for opportunities ( P = 0.01). There was a decrease in the perceived negative impact that attending medical schools without a home program will have on their abilities to pursue careers in plastic surgery ( P = 0.006). CONCLUSIONS: After the event, participants demonstrated an increase in their confidence in overcoming barriers and a decrease in their perceptions that attending an institution without a home program would negatively impact their ability to pursue plastic surgery. Initiatives focused on early exposure and recruitment of medical students may be important to promote accessibility and diversity within plastic surgery.

RESUMO

INTRODUCTION: Plastic and Reconstructive Surgeons are often presented with reconstructive challenges as a sequela of complications in high-risk surgical patients, ranging from exposure of hardware, lymphedema, and chronic pain after amputation. These complications can result in significant morbidity, recovery time, resource utilization, and cost. Given the prevalence of surgical complications managed by Plastic and Reconstructive Surgeons, developing novel preventative techniques to mitigate surgical risk is paramount. METHODS: Herein, we aim to understand efforts supporting the nascent field of Preventive Surgery, including (1) enhanced risk stratification, (2) medical optimization and prehabilitation, (3) surgical mitigation techniques, and (4) advancements in postoperative care. Through an emphasis on four surgical cohorts who may benefit from preventive surgery, two of which are at high risk of morbidity from wound-related complications (patients undergoing sternotomy and spine procedures) and two at high risk of other morbidities, including lymphedema and neuropathic pain, we aim to provide a comprehensive and improved understanding of preventive surgery. Additionally, the role of risk analysis for these procedures and the relationship between microsurgery and prophylaxis is emphasized. CONCLUSIONS: Reconstructive surgeons are ideally placed to lead efforts in the creation and validation of accurate risk-assessment tools and to support algorithmic approaches to surgical risk mitigation. Through a paradigm shift, including universal promotion of the concept of "Preventive Surgery," major improvements in surgical outcomes may be achieved.

RESUMO

BACKGROUND: Recent CMS billing changes have raised concerns about insurance coverage for deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study compared the costs and utilization of transverse rectus abdominis myocutaneous (TRAM), DIEP, and latissimus dorsi (LD) flaps in breast reconstruction. METHOD: The study utilized the National Inpatient Sample database to identify female patients who underwent DIEP, TRAM, and LD flap procedures from 2016 to 2019. Key data such as patient demographics, length of stay, complications, and costs (adjusted to 2021 USD) were analyzed, focusing on differences across the flap types. RESULTS: A total of 17,770 weighted patient encounters were identified, with the median age being 51. The majority underwent DIEP flaps (73.5%), followed by TRAM (14.2%) and LD (12.1%) flaps. The findings revealed that DIEP and TRAM flaps had a similar length of stay (LOS), while LD flaps typically had a shorter LOS. The total hospital charges to costs using cost-to-charge ratio were also comparable between DIEP and TRAM flaps, whereas LD flaps were significantly less expensive. Factors such as income quartile, primary payer of hospitalization, and geographic region significantly influenced flap choice. CONCLUSION: The study's results appear to contradict the prevailing notion that TRAM flaps are more cost-effective than DIEP flaps. The total hospital charges to costs using cost-to-charge ratio and hospital stays associated with TRAM and DIEP flaps were found to be similar. These findings suggest that changes in the insurance landscape, which may limit the use of DIEP flaps, could undermine patient autonomy while not necessarily reducing healthcare costs. Such policy shifts could favor less costly options like the LD flap, potentially altering the landscape of microvascular breast reconstruction.

RESUMO

Immediate lymphatic reconstruction (ILR) is recognized as a surgical approach used to reduce the risk of developing secondary lymphedema, and evidence demonstrating the efficacy of ILR is favorable. Our Lymphatic Center has become a centralized location offering ILR for the risk-reduction in breast cancer-related lymphedema (BCRL) in New England. Over the course of our experience, we made several modifications and adapted our approach to enhance the operative success of this procedure. These include advancements in our use of indocyanine green (ICG) imaging to identify baseline lymphatic anatomical variation, utilization of fluorescein isothiocyanate for lymphatic vessel visualization, application of the lymphosome concept to guide arm injection sites, verification of anastomotic patency (using ICG), localization of reconstruction to guide radiation therapy, incorporation of intraoperative tools to facilitate better anatomic visualization of the axilla, and addition of a lower extremity vein graft to mitigate venous-related complications. Collecting information from each surgery in a standardized manner, including intraoperative lymphatic channel measurements, and deploying clips for possible future radiation exposure, enables future studies on ILR patient outcomes. In this contribution, we aimed to share our institutional modifications with the surgical community to facilitate further adoption, conversation, and advancement of ILR for the risk-reduction in BCRL.

RESUMO

INTRODUCTION: On most online platforms, just about anyone can disseminate plastic surgery (PS) content regardless of their educational or professional background. This study examines the general public's perceptions of the accuracy of online PS content and the factors that contribute to the discernment of credible information. METHODS: The Amazon Mechanical Turk crowdsourcing platform was used to survey adults in the United States. The survey assessed respondent demographics, health literacy (HL), and perceptions of online PS content accuracy. T-tests, Chi-square tests, and post hoc analyses with Bonferroni corrections assessed differences between HL groups. Multivariate linear regressions assessed associations between sociodemographic variables and perceptions of online content. RESULTS: In total, 428 (92.0%) of 465 complete responses were analyzed. The median age of respondents was 32 y (interquartile range: 29-40). Online sources were predominantly perceived to have a high degree of accuracy, with mean scores of various platforms ranging from 3.8 to 4.5 (1 = not accurate at all; 5 = extremely accurate). The low HL group perceived social media sites and review sites to be more accurate than the high HL respondents, particularly for Reddit (P = 0.004), Pinterest (P = 0.040), and Snapchat (P = 0.002). CONCLUSIONS: There is a concerning relationship between low HL and the perceptions of the accuracy of online PS sources. This study underscores the need for education campaigns, the development of trustworthy online resources, and initiatives to improve HL. By fostering a more informed public, individuals seeking PS can make better informed decisions.

RESUMO

Management of burn injuries is complex, with highly variable outcomes occurring among different populations. This meta-analysis aims to assess the outcomes of burn therapy in North American (NA) and European adults, specifically, mortality and complications, to guide further therapeutic advances. A systematic review of PubMed, Web of Science, and Cochrane was performed. Random-effect meta-analysis of proportions was conducted to assess the overall prevalence of the defined outcomes. Fifty-four studies were included, pooling 60,269 adult patients. A total of 53,896 patients were in North America (NA, 89.4%), and 6,373 were in Europe (10.6%). Both populations experienced similar outcomes. The overall pooled prevalence of mortality was 13% (95% CI 8-19%) for moderate burns and 20% (95% CI 12-29%) for severe burns in the NA region, and 22% (95% CI 16-28%) for severe burns in Europe. Infectious complications were the most common across both regions. European studies showed an infection rate for moderate and severe burn patients at 8% and 76%, respectively, while NA studies had rates of 35% and 54%. Acute kidney injury (39% vs. 37%) and shock (29% vs. 35%), were the next most common complications in European and NA studies, respectively. The length of stay was 27.52 days for severe burn patients in Europe and 31.02 days for severe burn patients in NA. Burn outcomes are similar between Western populations. While outcomes are reasonably good overall, infectious complications remain high. These findings encourage the development of further therapeutic strategies disclosing respective costs to enable cost/efficiency evaluations in burn management.

RESUMO

BACKGROUND: The recent proposed alterations to the Centers for Medicare and Medicaid Services regulations, although subsequently reversed on August 21, 2023, have engendered persistent concerns regarding the impact of insurance policies on breast reconstruction procedures coverage. This study aimed to identify factors that would influence women's preferences regarding autologous breast reconstruction to better understand the possible consequences of these coverage changes. METHODS: A survey of adult women in the United States was conducted via Amazon Mechanical Turk to assess patient preferences for breast reconstruction options, specifically deep inferior epigastric perforator (DIEP) and transverse rectus abdominis myocutaneous (TRAM) flap surgery. The Cochrane-Armitage test evaluated trends in flap preferences concerning incremental out-of-pocket payment increases. RESULTS: Of 500 total responses, 485 were completed and correctly answered a verification question to ensure adequate attention to the survey, with respondents having a median (interquartile range) age of 26 (25-39) years. When presented with the advantages and disadvantages of DIEP versus TRAM flaps, 78% of respondents preferred DIEP; however, as DIEP's out-of-pocket price incrementally rose, more respondents favored the cheaper TRAM option, with $3804 being the "indifference point" where preferences for both procedures converged (P < 0.001). Notably, respondents with a personal history of breast reconstruction showed a higher preference for DIEP, even at a $10,000 out-of-pocket cost (P = 0.04). CONCLUSIONS: Out-of-pocket cost can significantly influence women's choices for breast reconstruction. These findings encourage a reevaluation of emergent insurance practices that could potentially increase out-of-pocket costs associated with DIEP flaps, to prevent cost from decreasing equitable patient access to most current reconstructive options.

RESUMO

BACKGROUND: This study aims to pioneer in evaluating women's representation in plastic surgery innovations, focusing on mammary prosthesis devices' inventorship. Despite growing gender parity in the field, women's involvement in innovation remains underexplored. This is especially crucial, as the predominant recipients of these innovative technologies are women, urging a necessity for broader female engagement in pioneering surgical advancements. METHOD: Patents under the "A61F2/12: Mammary prostheses and implants" classification between the dates January 1, 2011, to December 31, 2020, were identified using Google Patents Advanced. Inclusion criteria included patents (not designs) in English and applications (not grants), with no litigation limitations. Data collected included ID, title, assignee (categorized as industry, academic, private, individual), inventors, and dates (priority, filing, and publication). Sex of inventors was identified with the literature validated gender API, with manual resolution of unresolved genders or with ga_accuracy scores of less than 75%. Data were analyzed using 2-tailed Student t tests, χ2 analysis, and Pearson correlation coefficient (significance set at P ≤ 0.05). RESULTS: Of the more than 130,000 plastic surgery patents in English identified between the 10-year period, 1355 were classified as A61F2/12. A total of 374 unique patents were included for analysis (841 duplicates were removed, and 140 patents were excluded because of non-English character author names). There was a significant increase in patents over the decade (from 15 in 2011 to 88 in 2020, R2 = 0.74, P < 0.05), with a decrease in number of inventors per patent (R2 = 0.12, P < 0.05). Of the 1102 total inventors, 138 were female (11.2%), with a 4-fold increase in representation over the decade (R2 = 0.58, P < 0.05), including increase in patents filed with a woman first inventor (0%-14.8%). Women were equally likely to be first 3 inventors versus middle to last inventors (12.8% vs 11.1%, respectively). CONCLUSIONS: Over a decade, mammary device innovations rose significantly. Although women inventors' representation improved, it remains disproportionate compared with women in residency/practice. Hence, interventions should aim to align inventor representation with training ratios, through institutional optimization, reducing gender segmentation, and enhancing funding opportunities.

RESUMO

BACKGROUND: Recent literature has established outpatient breast reconstruction (BR) to be a safe alternative to inpatient BR. However, the impact of race and ethnicity on BR patient decision-making and postsurgical outcomes remains unexplored. This study aims to assess the impact of race and ethnicity on outpatient BR timing and postoperative complication rates. METHODS: The 2013-2020 ACS-NSQIP database was utilized to identify women undergoing outpatient BR. Propensity score-matched analysis was conducted to generate balanced cohorts based on race and ethnicity. t-tests and Fisher's exact tests were used to assess group differences. Logistic regressions were modeled to evaluate differences in complications between groups. RESULTS: A total of 63,526 patients underwent outpatient BR. After propensity score matching, 7664 patients and 3948 patients were included in the race and ethnicity-based analysis, respectively. There were statistically significant differences in the timing of BR patients received across cohorts. NW patients had lower rates of immediate BR (IBR) compared with White patients (47% vs. 53%, p < 0.001), and this also was seen in Hispanic patients (97% vs. 3%, p = 0.018). Subsequently, there were higher rates of delayed BR (DBR) in the NW cohort (55% vs. 45%, p < 0.001) and in the Hispanic cohort (95% vs. 5%, p = 0.018). There were no significant differences in the rates of 30-day postoperative complications across cohorts. CONCLUSIONS: Ultimately, our findings suggest that minority patients are more likely to undergo DBR than nonminority patients. However, there were no differences in 30-day postoperative outcomes across race or ethnicity. Future studies to elucidate patients' decision-making process in choosing optimal BR types and timing are necessary to better understand the impact of the observed differences in patient care.

RESUMO

In 1993, the National Institutes of Health Revitalization Act mandated increasing minority and women enrollment in clinical trials (CTs). This study aimed to investigate trends in race and ethnicity enrollment and reporting in US plastic and reconstructive surgery (PRS) CT. METHODS: A comprehensive systematic review was performed. All CTs in PRS from 2012 to 2022 were included. To assess racial and ethnic representation within CTs, a random-effects meta-analysis of proportion was conducted to pool the prevalence of the binomial data. RESULTS: A total of 3609 studies were initially identified in the search strategy, with 154 later classified as CTs in PRS. Only 36 met the eligibility criteria for reporting race and ethnicity and were included in the analysis. A total of 7281 participants were included: 446 (6.1%) males and 6835 (93.9%) females. From CTs that correctly reported race, the pooled prevalence of races were as follows: Whites 78% (95% confidence interval [CI] 73-82%), Black or African Americans 8% (95% CI 5-11%), Asians 1% (95% CI <1-2%), American Indians <1% (95% CI <1-<1%), and Pacific Islanders <1% (95% CI <1-<1%). From the studies that reported ethnicity correctly, the pooled prevalence of Hispanics was 7% (95% CI 5-9%), and Non-Hispanics was 12% (<1-38%). CONCLUSIONS: Disparities in minority representation were present among PRS CTs. This suggests clear limitations in generalizing PRS CT results to the population. Efforts to decrease the gap in minority enrollment and accurately report race and ethnicity are needed in all fields, including plastic surgery.

RESUMO

BACKGROUND: Patient-reported outcomes (PROs) have evolved to validated questionnaires assessing health-related quality of life. This systematic review evaluates the utilization of PROs in United States plastic and reconstructive surgery (PRS) clinical trials (CTs). METHODS: A medical librarian conducted a search strategy for PRS CTs from 2012 to 2022. CTs were identified and assessed for PRO utilization. Summary statistics were performed, and Fisher's exact test was used for subgroup analysis. RESULTS: Of the 3609 studies initially identified, 154 were PRS CTs. Approximately half (80 studies) employed PROs, encompassing 13,190 participants, 95% (12,229) of whom were female. Among the CTs, 37 (48%) were in the field of reconstruction, while 25 (32%) were cosmetic. Pain (35%) and patient satisfaction (24%) were the most common primary outcomes. Validated PROs were the main outcome in 61% of these trials, with the visual analog scale (19%) and BREAST-Q (15%) as the top instruments. Funding was primarily private (34%) or not reported (49%). No significant trend in validated PRO usage was observed over the examined decade. CONCLUSIONS: The use of PROs is relevant for healthcare delivery and improvement as they provide insight into the efficacy of treatments from a patient-centered viewpoint. PROs are reported in just over half of PRS CTs, and within those CTs, the use of validated questionnaires is inconsistent. Therefore, emerging CTs should strive to incorporate PRO measures and utilize the existing validated tools to assess novel interventions and ensure that the data reported is objective.

RESUMO

BACKGROUND: There has been a greater focus in recent literature proposing air to be a superior medium to saline in tissue expanders. This study aims to review the literature and assess the quality of data on the efficacy and safety of air as an alternative medium to saline in tissue expanders, in the setting of postmastectomy two-stage reconstruction. METHODS: A systematic review regarding air inflation of tissue expanders was conducted using PubMed, Embase, Cochrane Library, and Web of Science. The methods followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Three reviewers separately performed data extraction and comprehensive synthesis. RESULTS: A total of 427 articles were identified in our search query, of which 11 met the inclusion criteria. Three pertained to inflation with room air, and eight pertained to inflation with CO2 using the AeroForm device. They were comparable to decreased overall complication rates in the room air/CO2 cohort compared to saline, although statistical significance was only observed in one of five two-arm studies. Investigating specific complications in the five two-arm studies, significantly lower rates of skin flap necrosis were only observed in two CO2-based studies. Studies rarely discussed other safety profile concerns, such as the impacts of air travel, radiation planning, and air extravasation beyond descriptions of select patients within the cohort. CONCLUSION: There is insufficient evidence to suggest improved outcomes with room air inflation of tissue expanders. Further work is needed to fully characterize the benefits and safety profiles of air insufflation before being adopted into clinical practice.

RESUMO

Despite being the world's largest single-flower, Rafflesia's biology and life history are still poorly understood due to its cryptic growth strategy on Tetrastigma vines. Previous studies have been mostly short-term, contrary to Rafflesia's long development period before blooming. Bud development and flower phenology of R. cantleyi was studied in a dipterocarp forest in Lata Jarum, Peninsular Malaysia. Seven populations, consisting of 247 buds, were monitored fortnightly for 65 months in two discrete studies between 2009 and 2018. The bud size distribution of R. cantleyi is dynamic, progressively changing from small flower buds to larger buds before flowering. Buds < 5.0 cm across had the slowest growth and highest mortality rates, while those > 15.0 cm across demonstrated accelerated growth. The bud growth profiles of the same site clustered distinctively regardless of sex with successful blooming rate that varied greatly between sites, prompting speculation about their relatedness to the sites' physical attributes. We reported the first female-dominated population in Rafflesia's life history. Rafflesia cantleyi's blooming rate at Lata Jarum is moderate to high, with non-seasonal flowering phenology as evident by the lack of synchronisation and consistency between flowering and local rainfall patterns. Based on the field data of the present study and the published information of other Rafflesia species, R. cantleyi's life cycle was estimated between 4.0 and 5.3 years. Our findings further explain Rafflesia's biology and life history and highlight the gap in knowledge of the natural habitats on the endoparasite's growth and fate potentially for future conservation and study.

RESUMO

BACKGROUND: Patients with breast cancer living in rural areas are less likely to undergo breast reconstruction. Further, given the additional training and resources required for autologous reconstruction, it is likely that rural patients face barriers to accessing these surgical options. Therefore, the purpose of this study is to determine if there are disparities in autologous breast reconstruction care among rural patients on the national level. METHODS: The Healthcare Cost and Utilization Project Nationwide Inpatient Sample Database was queried from 2012 to 2019 using ICD9/10 codes for breast cancer diagnoses and autologous breast reconstruction. The resulting data set was analyzed for patient, hospital, and complication-specific information with counties comprised of less than 10,000 inhabitants classified as rural. RESULTS: From 2012 to 2019, 89,700 weighted encounters for autologous breast reconstruction involved patients who lived in non-rural areas, while 3605 involved patients from rural counties. The majority of rural patients underwent reconstruction at urban teaching hospitals. However, rural patients were more likely than non-rural patients to have their surgery at a rural hospital (6.8% vs. 0.7%). Rural-county residing patients had lower odds of receiving a deep inferior epigastric perforator (DIEP) flap compared to non-rural-county residing patients (OR 0.51 CI: 0.48-0.55, p < .0001). Further, rural patients were more likely to experience infection and wound disruption than urban patients (p < .05), regardless of where they underwent surgery. Complication rates were similar among rural patients who received care at rural hospitals versus urban hospitals (p > .05). Meanwhile, the cost of autologous breast reconstruction was higher (p = .011) for rural patients at an urban hospital ($30,066.2, SD19,965.5) than at a rural hospital ($25,049.5, SD12,397.2). CONCLUSION: Patients living in rural areas face disparities in health care, including lower odds of being potentially offered gold-standard breast reconstruction treatments. Increased microsurgical option availability and patient education in rural areas may help alleviate current disparities in breast reconstruction.

RESUMO

BACKGROUND: Older and frailer patients are increasingly undergoing free or pedicled tissue transfer for lower extremity (LE) limb salvage. This novel study examines the impact of frailty on postoperative outcomes in LE limb salvage patients undergoing free or pedicled tissue transfer. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database (2010-2020) was queried for free and pedicled tissue transfer to the LE based on Current Procedural Terminology and the International Classification of Diseases9/10 codes. Demographic and clinical variables were extracted. The five-factor modified frailty index (mFI-5) was calculated using functional status, diabetes, chronic obstructive pulmonary disease, congestive heart failure, and hypertension. Patients were stratified by mFI-5 score: no frailty (0), intermediate frailty (1), and high frailty (2 + ). Univariate analysis and multivariate logistic regression were performed. RESULTS: In total, 5,196 patients underwent free or pedicled tissue transfer for LE limb salvage. A majority were intermediate (n = 1,977) or high (n = 1,466) frailty. High frailty patients had greater rates of comorbidities-including those not in the mFI-5 score. Higher frailty was associated with more systemic and all-cause complications. On multivariate analysis, the mFI-5 score remained the best predictor of all-cause complications-with high frailty associated with 1.74 increased adjusted odds when compared with no frailty (95% confidence interval: 1.47-2.05). CONCLUSION: While flap type, age, and diagnosis were independent predictors of outcomes in LE flap reconstruction, frailty (mFI-5) was the strongest predictor on adjusted analysis. This study validates the mFI-5 score for preoperative risk assessment for flap procedures in LE limb salvage. These results highlight the likely importance of prehabilitation and medical optimization prior to limb salvage.

RESUMO

BACKGROUND: Empowerment is the process by which patients gain greater control of their health through active and informed decision-making. Greater patient empowerment has been shown to be positively correlated with improved health care outcomes and experiences. It is unclear how social media affect plastic and reconstructive surgery (PRS) patients' health care decision-making. This study aimed to help quantify how social media sites influence levels of PRS patient empowerment. METHODS: In this cross-sectional study, a modified Cyber Info-Decisional Empowerment Scale (CIDES) survey was distributed through Amazon Mechanical Turk (MTurk) to US adults. Sociodemographic characteristics, PRS history, and social media usage data were collected. Wilcoxon signed-rank and Kruskal-Wallis tests were used to assess for heterogeneity for categorical variables. ANOVA and t tests were used to evaluate differences in means for Likert scale-based responses. RESULTS: A total of 473 survey responses were included. The participants were grouped based on their surgical history: cosmetic [187 (39.5%)], reconstructive [107 (22.6%)], both cosmetic and reconstructive [36 (7.6%)], or non-PRS [143 (30.2%)]. There was increased empowerment depending on the online resources used. Social media use was associated with significantly greater empowerment in six of seven CIDES categories. Of the social media platforms, Facebook was associated with higher empowerment in three of seven CIDES categories. CONCLUSION: Social media use appears to have a positive impact on PRS patient empowerment, which may reflect better patient decision-making and autonomy when consulting with their plastic surgeon.

RESUMO

BACKGROUND: Use of pedicled flaps in vascular procedures is associated with decreased infection and wound breakdown. We evaluated the risk profile and postoperative complications associated with lower extremity open vascular procedures with and without pedicled flaps. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database (2010-2020) was queried for Current Procedural Terminology codes representing lower extremity open vascular procedures, including trunk and lower extremity pedicled flaps. Flap patients were compared with a randomized control group without flaps (1:3 cases to controls). Univariate and multivariate analyses were performed. RESULTS: We identified 132,934 adults who underwent lower extremity open vascular procedures. Concurrent pedicled flaps were rare (0.7%), and patients undergoing bypass procedures were more likely to receive a flap than nonbypass patients (69 vs. 64%, p < 0.0001). Flap patients had greater comorbidities. On univariate analysis, flap patients were more likely to experience wound (p = 0.0026), mild systemic (p < 0.0001), severe systemic (p = 0.0452), and all-cause complications (p < 0.0001). After adjusting for factors clinically suspected to be associated with increased risk (gender, body mass index, procedure type, American Society of Anesthesiologists classification, functional status, diabetes, smoking, and albumin < 3.5 mg/dL), wound (p = 0.096) and severe systemic complications (p = 0.0719) were no longer significantly associated with flap patients. CONCLUSION: Lower extremity vascular procedures are associated with a high risk of complications. Use of pedicled flaps remains uncommon and more often performed in patients with greater comorbid disease. However, after risk adjustment, use of a pedicled flap in high-risk patients may be associated with lower than expected wound and severe systemic complications.
