Social inequity in health among patients with severe obesity and multimorbidity.

INTRODUCTION: Obesity adversely affects the health of the individual and impacts society through increased healthcare costs and lost workdays. Individuals in lower socioeconomic groups are more severely affected. Here, we examined people living with severe obesity and comorbidities across educational levels. METHODS: Individuals with a BMI ≥ 35 kg/m2 and aged ≥ 16 years from the Danish National Health Survey 2021 were categorised into five educational levels and according to their number of obesity-related comorbidities (0, 1, 2 and ≥ 3). RESULTS: A total of 5.8% had a BMI ≥ 35 kg/m2, ranging from 2.2% to 10.7% in the 98 municipalities, and from 2.6% to 8.8% according to education level. Among individuals with a BMI ≥ 35 kg/m2 and the shortest education, 13.4% had no comorbidities, and 45.6% had ≥ 3 comorbidities. In contrast, among individuals with a BMI ≥ 35 kg/m2 and the longest education, 47.4% had no comorbidities, and 14.6% had ≥ 3 comorbidities. Among those with a BMI ≥ 35 kg/m2 and ≥ 3 comorbidities, 73.6% had elementary or vocational school as their highest education level, and 3.4% had a long higher education. CONCLUSIONS: The prevalence of individuals living with a BMI ≥ 35 kg/m2 differs by 3-5-fold depending on municipality and between the lowest and highest educational level. Additionally, the less educated group living with a BMI ≥ 35 kg/m2 was three times more likely to have ≥ 3 comorbidities than the most educated group. Hence, more research is warranted to understand the underlying causes and reduce social inequity in health. FUNDING: Novo Nordisk Fonden. TRIAL REGISTRATION: Not relevant.

Bariatric surgery and the diseased kidney: a 5-year assessment of safety and postoperative renal outcomes.

BACKGROUND: Obesity and its related medical conditions are well-established contributors to the development of chronic kidney disease (CKD). Metabolic and bariatric surgery (MBS), including procedures such as sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB), is a potential intervention for these individuals. However, the heightened risk of postoperative complications casts doubts on the suitability of MBS in this population. Our aim is to evaluate the long-term safety, anthropometric and renal outcomes of MBS in patients with CKD. METHODS: A retrospective review of patients who underwent primary laparoscopic MBS with a BMI ≥ 35 kg/m2 and a preoperative diagnosis of stage 2 to 5 CKD. Criteria for CKD diagnosis and staging were based on estimated glomerular filtration rate measurements in accordance with established guidelines. Anthropometric and renal outcomes were measured at 3-, 6-, 12-, 24- and 60-months postoperatively. RESULTS: A total of 302 patients (177 SG, 125 RYGB) were included. RYGB was preferred for patients with stage 3 CKD, while SG was more common in stages 4 and 5. At 5-year follow-up, percentage of total weight loss was higher in the RYGB cohort compared to SG (25.1% vs. 18.6%, p = 0.036). Despite SG patients having more advanced CKD, the incidence of late complications was significantly higher following RYGB, with 11 incidents (8.8%), compared to the SG cohort with only 4 cases (2.3%) (p = 0.014). In those with preoperative CKD stage 3, 76 patients (43.2%) improved to stage 2, with another 9 patients (5.1%) improving further to stage 1. Of all patients, 63 (20.8%) eventually received a successful renal transplant. CONCLUSIONS: MBS is an effective strategy for sustained weight loss in patients with CKD with acceptable complications rates. RYGB leads to a higher percentage of overall weight loss, albeit with an elevated likelihood of late surgical complications. Future studies are needed to determine the safety of MBS in this demographic.

Financial Incentives and Treatment Outcomes in Adolescents With Severe Obesity: A Randomized Clinical Trial.

Importance: Adolescent severe obesity is usually not effectively treated with traditional lifestyle modification therapy. Meal replacement therapy (MRT) shows short-term efficacy for body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) reduction in adolescents, and financial incentives (FIs) may be an appropriate adjunct intervention to enhance long-term efficacy. Objective: To evaluate the effect of MRT plus FIs vs MRT alone on BMI, body fat, and cardiometabolic risk factors in adolescents with severe obesity. Design, Setting, and Participants: This was a randomized clinical trial of MRT plus FIs vs MRT alone at a large academic health center in the Midwest conducted from 2018 to 2022. Participants were adolescents (ages 13-17 y) with severe obesity (≥120% of the 95th BMI percentile based on sex and age or ≥35 BMI, whichever was lower) who were unaware of the FI component of the trial until they were randomized to MRT plus FIs or until the end of the trial. Study staff members collecting clinical measures were blinded to treatment condition. Data were analyzed from March 2022 to February 2024. Interventions: MRT included provision of preportioned, calorie-controlled meals (~1200 kcals/d). In the MRT plus FI group, incentives were provided based on reduction in body weight from baseline. Main Outcomes and Measures: The primary end point was mean BMI percentage change from randomization to 52 weeks. Secondary end points included total body fat and cardiometabolic risk factors: blood pressure, triglyceride to high-density lipoprotein ratio, heart rate variability, and arterial stiffness. Cost-effectiveness was additionally evaluated. Safety was assessed through monthly adverse event monitoring and frequent assessment of unhealthy weight-control behaviors. Results: Among 126 adolescents with severe obesity (73 female [57.9%]; mean [SD] age, 15.3 [1.2] years), 63 participants received MRT plus FIs and 63 participants received only MRT. At 52 weeks, the mean BMI reduction was greater by -5.9 percentage points (95% CI, -9.9 to -1.9 percentage points; P = .004) in the MRT plus FI compared with the MRT group. The MRT plus FI group had a greater reduction in mean total body fat mass by -4.8 kg (95% CI, -9.1 to -0.6 kg; P = .03) and was cost-effective (incremental cost-effectiveness ratio, $39 178 per quality-adjusted life year) compared with MRT alone. There were no significant differences in cardiometabolic risk factors or unhealthy weight-control behaviors between groups. Conclusions and Relevance: In this study, adding FIs to MRT resulted in greater reductions in BMI and total body fat in adolescents with severe obesity without increased unhealthy weight-control behaviors. FIs were cost-effective and possibly promoted adherence to health behaviors. Trial Registration: ClinicalTrials.gov Identifier: NCT03137433.

Is the QCI framework suited for monitoring outcomes and costs in a teaching hospital using value-based healthcare principles? A retrospective cohort study.

OBJECTIVES: The objective is to develop a pragmatic framework, based on value-based healthcare principles, to monitor health outcomes per unit costs on an institutional level. Subsequently, we investigated the association between health outcomes and healthcare utilisation costs. DESIGN: This is a retrospective cohort study. SETTING: A teaching hospital in Rotterdam, The Netherlands. PARTICIPANTS: The study was performed in two use cases. The bariatric population contained 856 patients of which 639 were diagnosed with morbid obesity body mass index (BMI) <45 and 217 were diagnosed with morbid obesity BMI ≥45. The breast cancer population contained 663 patients of which 455 received a lumpectomy and 208 a mastectomy. PRIMARY AND SECONDARY OUTCOME MEASURES: The quality cost indicator (QCI) was the primary measures and was defined asQCI = (resulting outcome * 100)/average total costs (per thousand Euros)where average total costs entail all healthcare utilisation costs with regard to the treatment of the primary diagnosis and follow-up care. Resulting outcome is the number of patients achieving textbook outcome (passing all health outcome indicators) divided by the total number of patients included in the care path. RESULTS: The breast cancer and bariatric population had the highest resulting outcome values in 2020 Q4, 0.93 and 0.73, respectively. The average total costs of the bariatric population remained stable (avg, €8833.55, min €8494.32, max €9164.26). The breast cancer population showed higher variance in costs (avg, €12 735.31 min €12 188.83, max €13 695.58). QCI values of both populations showed similar variance (0.3 and 0.8). Failing health outcome indicators was significantly related to higher hospital-based costs of care in both populations (p <0.01). CONCLUSIONS: The QCI framework is effective for monitoring changes in average total costs and relevant health outcomes on an institutional level. Health outcomes are associated with hospital-based costs of care.

Increasing disparities in obesity and severe obesity prevalence among public elementary and middle school students in New York City, school years 2011-12 through 2019-20.

Recent national trends in the United States indicate a significant increase in childhood obesity, a major public health concern with documented physical and mental comorbidities and sociodemographic disparities. We aimed to estimate the prevalence of obesity and severe obesity among youth in New York City (NYC) before the COVID-19 pandemic and examine time trends overall and by key characteristics. We included all valid height and weight measurements of kindergarten through 8th grade public school students aged 5 to 15 from school years 2011-12 through 2019-20 (N = 1,370,890 unique students; 5,254,058 observations). Obesity and severe obesity were determined using age- and sex-specific body mass index percentiles based on the Centers for Disease Control and Prevention growth charts. Analyses were performed using multivariate logistic regression models with repeated cross-sectional observations weighted to represent the student population for each year and clustered by student and school. Among youth attending public elementary and middle schools in NYC, we estimate that 20.9% and 6.4% had obesity and severe obesity, respectively, in 2019-20. While consistent declines in prevalence were observed overall from 2011-12 to 2019-20 (2.8% relative decrease in obesity and 0.2% in severe obesity, p<0.001), increasing trends were observed among Black, Hispanic, and foreign-born students, suggesting widening disparities. Extending previous work reporting prevalence estimates in this population, nearly all groups experienced significant increases in obesity and severe obesity from 2016-17 to 2019-20 (relative change = 3.5% and 6.7%, respectively, overall; p<0.001). Yet, some of the largest increases in obesity were observed among those already bearing the greatest burden, such as Black and Hispanic students and youth living in poverty. These findings highlight the need for greater implementation of equity-centered obesity prevention efforts. Future research should consider the influence of the COVID-19 pandemic and changes in clinical guidance on childhood obesity and severe obesity in NYC.

Racial Disparity in Length of Stay Following Implementation of a Bariatric Enhanced Recovery Program.

INTRODUCTION: Enhanced Recovery Programs (ERPs) mitigate racial disparities in postoperative length of stay (LOS) for colorectal populations. It is unclear, however, if these effects exist in the bariatric surgery population. Therefore, this study aimed to evaluate the racial disparities in LOS before and after implementation of bariatric surgery ERP. METHODS: A retrospective cohort study was performed using data from a single institution. Patients undergoing minimally invasive sleeve gastrectomy or Roux-en-Y gastric bypass from 2017 to 2019 (pre-ERP) or 2020-2022 (ERP) were included. Chi-square, Kruskal-Wallis, and analysis of variance were used to compare groups, and estimated LOS (eLOS) was assessed via multivariable regression. RESULTS: Seven hundred sixty four patients were identified, including 363 pre-ERPs and 401 ERPs. Pre-ERP and ERP cohorts were similar in age (median 44.3 years versus 43.8 years, P = 0.80), race (53.4% Black versus 56.4% Black, P = 0.42), and preoperative body mass index (median 48.3 versus 49.4, P = 0.14). Overall median LOS following bariatric surgery decreased from 2 days pre-ERP to 1 day following ERP (P < 0.001). Average LOS for Black and White patients decreased by 0.5 and 0.48 days, respectively. However, overall eLOS remained greater for Black patients compared with White patients despite ERP implementation (eLOS 0.21 days, P = 0.01). CONCLUSIONS: Implementation of a bariatric surgery ERP was associated with decreased LOS for both Black and White patients. However, Black patients did have slightly longer LOS than White patients in both pre-ERP and ERP eras. More work is needed to understand the driving mechanism(s) of these disparities to eliminate them.

A commentary review on endoscopic sleeve gastroplasty: Indications, outcomes and future implications.

Metabolic and bariatric surgeries have been shown to be the most effective strategy to induce and maintain significant weight loss for people living with severe obesity. However, ongoing concerns regarding operative risks, irreversibility and excess costs limit their broader clinical use. Endoscopic bariatric therapies are pragmatic alternatives for patients who are not suitable for metabolic and bariatric surgeries or who are concerned regarding their long-term safety. Endoscopic sleeve gastroplasty has emerged as a novel technique of endoscopic bariatric therapies, which have garnered significant interest and evidence in the past few years. Its safety, efficacy and cost-effectiveness have been shown in various studies, while comparisons with sleeve gastrectomy have been widely made. This review brings together current evidence pertaining to the technicality of the procedure itself, current indications, safety and efficacy, cost-effectiveness, as well as its future role and development.

Changes in plasma concentrations of per- and Polyfluoroalkyl substances after bariatric surgery in adolescents from the Teen-Longitudinal Assessment of Bariatric Surgery (Teen-LABS) study.

Exposure to per- and poly-fluoroalkyl substances (PFAS) is ubiquitous due to their persistence in the environment and in humans. Extreme weight loss has been shown to influence concentrations of circulating persistent organic pollutants (POPs). Using data from the multi-center perspective Teen-Longitudinal Assessment of Bariatric Surgery (Teen-LABS) cohort, we investigated changes in plasma-PFAS in adolescents after bariatric surgery. Adolescents (Mean age = 17.1 years, SD = 1.5 years) undergoing bariatric surgery were enrolled in the Teen-LABS study. Plasma-PFAS were measured at the time of surgery and then 6-, 12-, and 36 months post-surgery. Linear mixed effect models were used to evaluate longitudinal changes in plasma-PFAS after the time of bariatric surgery. This study included 214 adolescents with severe obesity who had available longitudinal measures of plasma-PFAS and underwent bariatric surgery between 2007 and 2012. Underlying effects related to undergoing bariatric surgery were found to be associated with an initial increase or plateau in concentrations of circulating PFAS up to 6 months after surgery followed by a persistent decline in concentrations of 36 months (p < 0.001 for all plasma-PFAS). Bariatric surgery in adolescents was associated with a decline in circulating PFAS concentrations. Initially following bariatric surgery (0-6 months) concentrations were static followed by decline from 6 to 36 months following surgery. This may have large public health implications as PFAS are known to be associated with numerous metabolic related diseases and the significant reduction in circulating PFAS in individuals who have undergone bariatric surgery may be related to the improvement of such metabolic related diseases following bariatric surgery.

Energy expenditure related biomarkers following bariatric surgery: a prospective six-month cohort study.

BACKGROUND: Mitochondria dysfunction is one of the major causes of insulin resistance, and other countless complications of obesity. PGC-1α, and UCP-2 play key roles in energy expenditure regulation in the mitochondrial thermogenesis. However, the effects of bariatric surgery on the level of PGC-1α and UCP-2 and their relationships are unclear. OBJECTIVE: This study aimed to investigate the effect of bariatric surgery on key pathways in energy, and to assess the potential predictive role of body composition and metabolic parameters in this regard. SETTINGS: Hazrat-e Rasool General Hospital, Center of Excellence of International Federation for Surgery of Obesity. METHODS: This prospective cohort study was carried out on 45 patients with morbid obesity who underwent Roux-en-Y gastric bypass surgery. The patients have evaluated three-time points at baseline, three, and six months after the surgery. Body composition components, the levels of PGC-1α, UCP-2, and metabolic parameters were measured three times during this study. RESULTS: Significant changes in TWL%, EBMIL%, and metabolic lab tests were observed at three- and six months post-surgery (P < 0.001). The PGC-1α and UCP-2 had a significant increase three and then six-month post-operation compared with the baseline (P < 0.001). Moreover, multivariate linear regression analysis identified that the changing trend of PGC-1α was associated with insulin, uric Acid, HOMA-IR, fat mass and trunk fat mass. UCP-2 was associated with TSH, AST, fat mass and FFM. CONCLUSIONS: Bariatric surgery has been shown to have a positive effect on UCP-2 and PGC-1α levels, as well as body composition and metabolic parameters. As a result, it is believed that bariatric surgery could improve thermogenesis and energy expenditure by enhancing mitochondrial biogenesis and function. However, further studies are needed to fully understand the precise mechanisms and possible causal relationship.

Development and Evaluation of a Quality Assessment Tool for Laparoscopic Sleeve Gastrectomy Videos: A Review and Comparison of Academic and Online Video Resources.

BACKGROUND: Video recording of surgical procedures is increasing in popularity. They are presented in various platforms, many of which are not peer-reviewed. Laparoscopic sleeve gastrectomy (LSG) videos are widely available; however, there is limited evidence supporting the use of reporting guidelines when uploading LSG videos to create a valuable educational video. We aimed to determine the variations and establish the quality of published LSG videos, in both peer-reviewed literature and on YouTube, using a newly designed checklist to improve the quality and enhance the transparency of video reporting. METHODS: A quality assessment tool was designed by using existing research and society guidelines, such as the Bariatric Metabolic Surgery Standardization (BMSS). A systematic review using PRISMA guidelines was performed on MEDLINE and EMBASE databases to identify video case reports (academic videos) and a similar search was performed on the commercial YouTube platform (commercial videos) simultaneously. All videos displaying LSG were reviewed and scored using the quality assessment tool. Academic and commercial videos were subsequently compared and an evidence-based checklist was created. RESULTS: A total of 93 LSG recordings including 26 academic and 67 commercial videos were reviewed. Mean score of the checklist was 5/11 and 4/11 for videos published in articles and YouTube, respectively. Academic videos had higher rates of describing instruments used, such as orogastric tube (P < 0.001) and stapler information (P = 0.04). Fifty-four percent of academic videos described short-term patient outcomes, while not reported in commercial videos (P < 0.001). Sleeve resection status was not universally reported. CONCLUSIONS: Videos published in the academic literature are describing steps in greater detail with more emphasis on specific technical elements and patient outcomes and thus have a higher educational value. A new quality assessment tool has been proposed for video reporting guidelines to improve the reliability and value of published video research.

Prediction of resting energy expenditure for adolescents with severe obesity: A multi-centre analysis.

BACKGROUND AND OBJECTIVES: Resting energy expenditure (REE) assessments can help inform clinical treatment decisions in adolescents with elevated body mass index (BMI), but current equations are suboptimal for severe obesity. We developed a predictive REE equation for youth with severe obesity and obesity-related comorbidities and compared results to previously published predictive equations. METHODS: Data from indirect calorimetry, clinical measures, and body composition per Dual x-ray absorptiometry (DXA) were collected from five sites. Data were randomly divided into development (N = 438) and validation (N = 118) cohorts. A predictive equation was developed using Elastic Net regression, using sex, race, ethnicity, weight, height, BMI percent of the 95th%ile (BMIp95), waist circumference, hip circumference, waist/hip ratio, age, Tanner stage, fat and fat-free mass. This equation was verified in the validation cohort and compared with 11 prior equations. RESULTS: Data from the total cohort (n = 556, age 15 ± 1.7 years, 77% female, BMIp95 3.3 ± 0.94) were utilized. The best fit equation was REE = -2048 + 18.17 × (Height in cm) - 2.57 × (Weight in kg) + 7.88 × (BMIp95) + 189 × (1 = male, 0 = female), R2 = 0.466, and mean bias of 23 kcal/day. CONCLUSION: This new equation provides an updated REE prediction that accounts for severe obesity and metabolic complications frequently observed in contemporary youth.

The impact of severe obesity on image quality and ventricular function assessment in echocardiography and cardiac MRI.

This study sought to evaluate the impact of severe obesity on image quality and ventricular function assessment in cardiovascular magnetic resonance (MRI) and trans-thoracic echocardiography (TTE). We studied 100 consecutive patients who underwent clinically indicated cardiac MRI and TTE studies within 12 months between July 2017 and December 2020; 50 (28 females and 22 males; 54.5 ± 18.7 years) with normal body mass index (BMI) (18.5-25 kg/m2) and 50 (21 females and 29 males; 47.2 ± 13.3 years) with severe obesity (BMI ≥ 40 kg/m2). MRI and TTE image quality scores were compared within and across cohorts using a linear mixed model. Categorical left (LVF) and right (RVF) ventricular function were compared using Cohens Kappa statistic. Mean BMI for normal weight and obese cohorts were 22.2 ± 1.7 kg/m2 and 50.3 ± 5.9 kg/m2, respectively. Out of a possible 93 points, mean MRI image quality score was 91.5 ± 2.5 for patients with normal BMI, and 88.4 ± 5.5 for patients with severe obesity; least square (LS) mean difference 3.1, p = 0.460. TTE scores were 64.2 ± 13.6 for patients with normal BMI and 46.0 ± 12.9 for patients with severe obesity, LS mean difference 18.2, p < 0.001. Ventricular function agreement between modalities was worse in the obese cohort for both LVF (72% vs 80% agreement; kappa 0.53 vs 0.70, obese vs. normal BMI), and RVF (58% vs 72% agreement, kappa 0.18 vs 0.34, obese vs. normal BMI). Severe obesity had limited impact on cardiac MRI image quality, while obesity significantly degraded TTE image quality and ventricular function agreement with MRI.

Adaptive thermogenesis, at the level of resting energy expenditure, after diet alone or diet plus bariatric surgery.

OBJECTIVE: The objective of this study was to compare the magnitude of adaptive thermogenesis (AT), at the level of resting energy expenditure (REE), after a very low-energy diet alone or combined with Roux-en-Y gastric bypass or sleeve gastrectomy, as well as to investigate the association between AT and changes in appetite. METHODS: A total of 44 participants with severe obesity underwent 10 weeks of a very low-energy diet alone or combined with Roux-en-Y gastric bypass or sleeve gastrectomy. Body weight and composition, REE, subjective appetite feelings, and plasma concentrations of gastrointestinal hormones were measured at baseline and week 11. AT, at the level of REE, was defined as a significantly lower measured versus predicted (using a regression model with baseline data) REE. RESULTS: Participants lost 18.4 ± 3.9 kg of body weight and experienced AT, at the level of REE (-121 ± 188 kcal/day; p < 0.001), with no differences among groups. The larger the AT, at the level of REE, the greater the reduction in fasting ghrelin concentrations and the smaller the reduction in feelings of hunger and desire to eat in the postprandial state. CONCLUSIONS: Weight-loss modality does not seem to modulate the magnitude of AT, at the level of REE. The greater the AT, at the level of REE, the greater the drive to eat following weight loss.

Association of prior bariatric surgery with outcomes following emergency general surgery.

BACKGROUND: Despite the favorable outcomes and safety profile associated with metabolic and bariatric surgery (MBS), complications may occur postoperatively, necessitating emergency general surgery (EGS) intervention. OBJECTIVES: To evaluate the association of outcomes in patients with prior MBS following EGS interventions. SETTING: Academic, University-affiliated; USA. METHODS: All adults undergoing nonelective EGS operations were identified using the 2016 to 2020 Nationwide Readmission Database. Patients with a history of MBS were subsequently categorized as Bariatric, with the remainder of patients as NonBariatric. The primary outcome of interest was in-hospital mortality, while perioperative complications, length of stay (LOS), hospitalization costs, non-home discharge, and 30-day readmission were secondarily assessed. Multivariable regression models were developed to evaluate the association of history of MBS with outcomes of interest. RESULTS: Of an estimated 632,375 hospitalizations for EGS operations, 29,112 (4.6%) had a history of MBS. Compared to Nonbariatric, Bariatric were younger, more frequently female and more commonly had severe obesity. Following risk adjustment, Bariatric had significantly lower odds of in-hospital mortality (AOR .83, 95%CI .71-.98). Compared to others, Bariatric had reduced LOS by .5 days (95%CI .4-.7) and hospitalization costs by $1600 (95%CI $900-2100). Patients with prior MBS had reduced odds of nonhome discharge (AOR .89, 95%CI .85-.93) and increased likelihood of 30-day readmissions (AOR 2.32, 95%CI 1.93--2.79) following EGS. CONCLUSIONS: Prior MBS is associated with decreased mortality and perioperative complications as well as reduced resource utilization in select EGS procedures. Our findings suggest that patients with a history of MBS can be managed effectively by acute surgical interventions.

The financial toxicity of postbariatric body contouring surgery: a survey study of an urban tertiary care center's patients.

BACKGROUND: Patients with obesity who undergo bariatric surgery achieve sustained weight loss but are often left with excess skin folds that cause functional and psychological deficits. To remove excess skin, patients can undergo postbariatric BCS; however, cost and lack of insurance coverage present a significant barrier for many patients. OBJECTIVES: This study aimed to characterize the financial impact of treatment on all patients who received bariatric surgery and to compare between those receiving only bariatric surgery and those with postbariatric BCS. SETTING: Email-based survey study at an urban tertiary care center. METHODS: Surveys that included the COST-FACIT were sent to patients with a history of bariatric surgery and/or post-bariatric BCS. RESULTS: One hundred and five respondents completed the survey, of which 19 reported having postbariatric BCS. Patients with postbariatric BCS had slightly higher COST scores than those receiving bariatric surgery only, but this difference was not significant (15.6 versus 17.8, P = .23). Most patients (76%) did not have an awareness of BCS or BCS cost prior to bariatric surgery, and many (68%) had more loose skin than anticipated. CONCLUSIONS: Financial toxicity was similar across all postbariatric surgery patients surveyed regardless of history of BCS. However, survey respondents noted a gap between patient education and expectations around loose skin and body contouring that can be addressed through improved presurgical counseling.

Economic Evaluations of Anti-obesity Interventions in Obese Adults: An Umbrella Review.

This umbrella review amalgamates the outcomes of economic evaluations pertaining to bariatric surgeries, pharmacotherapy, and gastric balloon for adult obesity treatment. Six databases were systematically searched. The inclusion criteria were established following the Patient/population Intervention Comparison and Outcomes (PICO) statement. Fifteen reviews met all the inclusion criteria. Eight studies focused on surgical interventions, four on pharmacotherapy, and three on both interventions. No systematic review of the economic evaluation of gastric balloons was identified. The majority of reviews advocated bariatric surgery as a cost-effective approach; however, there was discordance in the interpretation of pharmacological cost-effectiveness. Most of the economic evaluations were conducted from the payer and the healthcare system perspectives. We propose that future economic evaluations assessing weight loss interventions in adults adopt a societal perspective and longer-term time horizons.

A New Procedure-Based Assessment of Operative Skills in Gastric Bypass Surgery, Evaluated by Video Fragment Rating.

PURPOSE: Feedback on technical and procedural skills is essential during the training of residents and fellows. The aim of this study was to assess the performance of a newly created instrument for the assessment of operative skills using laparoscopic Roux-en-Y gastric bypass (LRYGB) video fragments. MATERIALS AND METHODS: A new procedure-based assessment (PBA) was created by combining LRYGB key steps with a 5-point independence scale. LRYGB performed by residents and surgeons with different levels of expertise were video recorded. Fragments of the pouch creation, gastro-jejunostomy and jejunojejunostomy, were review by 12 expert bariatric surgeons and the operative skills assessed with the PBA, Objective Structured Assessment of Technical Skill (OSATS), and the Bariatric OSATS (BOSATS). The PBA was compared to the OSATS and BOSATS. Mean scores for all items of the different assessments were summarized and compared using a T-test. RESULTS: The scores of the procedural steps were combined and compared for all levels. The mean scores for beginner, intermediate, and expert level were 2.71, 3.70, and 3.90 for the PBA; for the OSATS 1.84, 2.86, and 3.44; and for the BOSATS 2.78, 3.56, and 4.19. Each of these assessments differentiated between the three skill levels (all p < 0.05). CONCLUSION: The PBA discriminates well between different levels of operative skills. Similar patterns were found for the OSATS and BOSATS, showing that the randomly selected video fragments are representative samples for assessing skill level. Future research will demonstrate whether these results can be extrapolated to clinical training, and which scores allow for procedure certification.
