van Veghel W, van Dijk SC, Klem TM, Weel AE, Bügel JB, Birnie E. Is the QCI framework suited for monitoring outcomes and costs in a teaching hospital using value-based healthcare principles? A retrospective cohort study. BMJ Open 2024; 14:e080257. [PMID: 38692726 PMCID: PMC11086573 DOI: 10.1136/bmjopen-2023-080257] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Accepted: 04/16/2024] [Indexed: 05/03/2024] Open
Abstract
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.

Obes Surg 2024; 34:1295-1305. [PMID: 38427149 DOI: 10.1007/s11695-024-07114-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Revised: 02/08/2024] [Accepted: 02/15/2024] [Indexed: 03/02/2024]
Abstract
BACKGROUND This study aims to evaluate and compare long-term results of laparoscopic sleeve gastrectomy (LSG) and one anastomosis gastric bypass (OAGB) based on bariatric analysis reporting and outcome system (BAROS) score. MATERIALS AND METHODS Patients operated for morbid obesity between 2013 and 2015 were randomised to LSG and OAGB groups. Based on inclusion and exclusion criteria, 201 patients (100 LSG and 101 OAGB) were analysed for changes in total body weight (TBW), body mass index (BMI), percent excess weight loss (%EWL), percent total weight loss (%TWL), QoL (quality of life) scores, comorbidity resolution and outcome based on BAROS at 7 years. RESULTS Sixty-six LSG and 64 OAGB patients were followed up at 7 years. Mean pre-operative TBW and BMI were 119 ± 28.2 and 44.87 ± 7.71 for LSG group and 113.25 ± 23.74 and 44.71 ± 8.75 for OAGB group respectively. At 7 years after surgery, there was significant drop in mean TBW and BMI in both groups. Mean %EWL for LSG and OAGB patients was 50.78 ± 28.48 and 59.99 ± 23.32 and mean %TWL for LSG and OAGB patients was 23.22 ± 12.66 and 27.71 ± 12.27 respectively. Mean QoL scores at 7 years were significantly higher than the pre-operative scores and most of the patients in both groups had remission or improvement in their comorbidities. 68.76% OAGB patients had very good or excellent outcome on BAROS score while only 36.37% LSG patients had similar outcome. CONCLUSIONS LSG and OAGB are successful bariatric procedures over the long term. OAGB outperforms LSG and has significantly higher %EWL and %TWL over the long term.

SF-6D Normative Values Among Patients Undergoing Bariatric Surgery: Results Based on Real-World Evidence from the Scandinavian Obesity Surgery Registry (SOReg). Obes Surg 2024; 34:558-567. [PMID: 38189900 PMCID: PMC10811135 DOI: 10.1007/s11695-023-07024-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 12/18/2023] [Accepted: 12/19/2023] [Indexed: 01/09/2024]
Abstract
BACKGROUND The SF-6D index can be used to calculate quality-adjusted life years in economic evaluations, which is required by reimbursement agencies and national advisory bodies, including the Swedish ones. However, despite that SF-36 has been largely applied among patients undergoing bariatric surgery, almost no study has accessed the short form six-dimensions (SF-6D) after bariatric surgery. AIM To establish normative values for the SF-6D index among patients undergoing bariatric surgery. MATERIALS AND METHODS All patients who received bariatric surgery in Sweden between 2011-01-01 and 2019-03-31 were obtained from the Scandinavian Obesity Surgery Registry (SOReg). Information includes patients' sociodemographic characteristics, details regarding the procedure, and postsurgical conditions. The SF-36 is applied at baseline and at follow-up years 1, 2, and 5. The multiple sequential imputation method was applied to handle missingness on SF-6D items. Based on the UK tariff, the SF-6D preference scores were calculated. The normative values for the mean (SD) SF-6D index were reported by timepoint and surgical complications for men and women, respectively. Multivariate analyses were applied to investigate how the SF-6D index is associated with timepoint, controlling for age, sex, BMI, and comorbidities in a stepwise manner. RESULTS The SF-6D index increased at 1 year relative to baseline and was roughly maintained at the same level at 2 years. The normative value of the SF-6D index can be used in economic evaluations for bariatric surgery.

Abstract
PURPOSE Bariatric and metabolic surgery is an effective treatment for severe and complex obesity; however, robust long-term data comparing operations is lacking. Clinical registries complement clinical trials in contributing to this evidence base. Agreement on standard data for bariatric registries is needed to facilitate comparisons. This study developed a Core Registry Set (CRS) - core data to include in bariatric surgery registries globally. MATERIALS AND METHODS Relevant items were identified from a bariatric surgery research core outcome set, a registry data dictionary project, systematic literature searches, and a patient advisory group. This comprehensive list informed a questionnaire for a two-round Delphi survey with international health professionals. Participants rated each item's importance and received anonymized feedback in round 2. Using pre-defined criteria, items were then categorized for voting at a consensus meeting to agree the CRS. RESULTS Items identified from all sources were grouped into 97 questionnaire items. Professionals (n = 272) from 56 countries participated in the round 1 survey of which 45% responded to round 2. Twenty-four professionals from 13 countries participated in the consensus meeting. Twelve items were voted into the CRS including demographic and bariatric procedure information, effectiveness, and safety outcomes. CONCLUSION This CRS is the first step towards unifying bariatric surgery registries internationally. We recommend the CRS is included as a minimum dataset in all bariatric registries worldwide. Adoption of the CRS will enable meaningful international comparisons of bariatric operations. Future work will agree definitions and measures for the CRS including incorporating quality-of-life measures defined in a parallel project.

Abstract
BACKGROUND Recent data describing gastrointestinal (GI) symptoms experienced by patients after bariatric surgery is lacking, and previous studies in sleeve gastrectomy patients have been limited in scope of follow-up time or extent of GI symptoms examined. We sought to characterize the prevalence and time course of patient-reported eating-related symptoms in sleeve gastrectomy patients. METHODS From July 2020 to July 2021, sleeve gastrectomy patients seen at three Boston area hospitals received electronic surveys and prospectively reported GI symptoms using the BODY-Q eating-related symptoms scale. Descriptive analyses were performed for patient demographics and symptom prevalence. Chi-square tests were used to compare prevalence of eating-related symptoms between follow-up time intervals. RESULTS 491 sleeve gastrectomy patients completed postoperative surveys with mean follow-up time of 1.9 years. Mean age was 46.6 years, and 81.3% were female. The most reported GI symptoms overall included constipation (56.6%), bloating (54.0%), heartburn when standing (41.5%), and heartburn when lying down (39.9%) while the least commonly reported symptoms were palpitations (16.3%), low blood sugar (15.7%), and emesis (15.1%). At greater than 12 months, the most reported symptoms similarly included bloating (60.3%), constipation (53.2%), and heartburn while standing (46.0%). When comparing prevalence of eating-related symptoms across follow-up time intervals from < 1 to > 12 months, patients reported a significant decrease in constipation, abdominal pain, and nausea over time (p = 0.012, p < .0001, p = 0.03, respectively). CONCLUSION Patients experience both upper and lower GI symptoms following sleeve gastrectomy, and symptoms, including bloating, constipation, and heartburn may persist through long-term follow-up. These patient-centered measures add value by guiding preoperative counseling, informing postoperative expectations, and providing real-time clinical feedback for bariatric surgery patients.

Abstract
PURPOSE Patient-reported measures are an important emerging metric in outcome monitoring; however, they remain ill-defined and underutilized in bariatric clinical practice. This study aimed to determine the characteristics of patient-reported measures employed in bariatric practices across Australia and Aotearoa New Zealand, including barriers to their implementation and to what extent clinicians are receptive to their use. METHODS An online survey was distributed to all bariatric surgeons actively contributing to the Australian and Aotearoa New Zealand Bariatric Surgery Registry (n = 176). Participants reported their use of patient-reported measures and identified the most important and useful outcomes of patient-reported data for clinical practice. RESULTS Responses from 64 participants reported on 120 public and private bariatric practices across Australia and Aotearoa New Zealand. Most participants reported no collection of any patient-reported measure (39 of 64; 60.9%), citing insufficient staff time or resources as the primary barrier to the collection of both patient-reported experience measures (34 of 102 practices; 33.3%) and patient-reported outcome measures (30 of 84 practices; 35.7%). Participants indicated data collection by the Registry would be useful (47 of 57; 82.5%), highlighting the most valuable application to be a monitoring tool, facilitating increased understanding of patient health needs, increased reporting of symptoms, and enhanced patient-physician communication. CONCLUSION Despite the current lack of patient-reported measures, there is consensus that such data would be valuable in bariatric practices. Widespread collection of patient-reported measures by registries could improve the collective quality of the data, while avoiding implementation barriers faced by individual surgeons and hospitals.

Abstract
Quality of life is a key outcome that is not rigorously measured in obesity treatment research due to the lack of standardization of patient-reported outcomes (PROs) and PRO measures (PROMs). The S.Q.O.T. initiative was founded to Standardize Quality of life measurement in Obesity Treatment. A first face-to-face, international, multidisciplinary consensus meeting was conducted to identify the key PROs and preferred PROMs for obesity treatment research. It comprised of 35 people living with obesity (PLWO) and healthcare providers (HCPs). Formal presentations, nominal group techniques, and modified Delphi exercises were used to develop consensus-based recommendations. The following eight PROs were considered important: self-esteem, physical health/functioning, mental/psychological health, social health, eating, stigma, body image, and excess skin. Self-esteem was considered the most important PRO, particularly for PLWO, while physical health was perceived to be the most important among HCPs. For each PRO, one or more PROMs were selected, except for stigma. This consensus meeting was a first step toward standardizing PROs (what to measure) and PROMs (how to measure) in obesity treatment research. It provides an overview of the key PROs and a first selection of the PROMs that can be used to evaluate these PROs.

Abstract
Background: Most studies analyzing the health-related quality of life (HRQOL) after bariatric treatment ceased at five years post-surgery or even earlier, and it is unclear whether the HRQOL benefit persists for a longer time. This paper reviews sparse evidence regarding HRQOL in patients who underwent bariatric surgery at least nine years prior. Materials and Methods: A of PubMed, Scopus and Google Scholar between 2007–2021 was carried out for the studies investigating HRQOL as an outcome measure in patients after bariatric surgery of any type and having at least a 9-year follow-up. Inconsistent reporting of weight loss or postgraduate study results unrelated to QoL were not included in the study. The study used the PICO procedure. Results: The review of 18 identified publications demonstrated that bariatric treatment seems to provide a persistent benefit in terms of HRQOL, especially its physical component score. Due to psychological predispositions, some patients appear to be less likely to benefit from bariatric treatment, whether in terms of HRQOL or bodyweight reduction. Inconsistent and imprecise studies may limit the evidence included in a review. Conclusions: The early identification of such patients and providing them with holistic care, including psychological intervention, would likely further improve the outcomes of bariatric treatment.

Abstract
BACKGROUND Health-Related Quality of Life (HRQL) is a key outcome of success after bariatric surgery. Not all patients report improved HRQL scores postoperatively, which may be due to patient-level factors. It is unknown which factors influence HRQL after surgery. Our objective was to assess patient-level factors associated with HRQL after surgery. METHODS This international cross-sectional study included 730 patients who had bariatric surgery. Participants completed BODY-Q scales pertaining to HRQL and satisfaction with body, and demographic characteristics were obtained. The sample was divided into three groups based on time since surgery: 0 - 1 year, 1 - 3 years and more than 3 years. Uni- and multivariable linear regression analyses were conducted to identify variables associated with the BODY-Q scales per group. RESULTS The 0 - 1 year postoperative group included 377 patients (50.9%), the 1 - 3 years postoperative group 218 (29.4%) and the more than 3 years postoperative group 135 patients (18.2%). Lower current body-mass index (BMI), more weight loss (%TWL), being employed, having no comorbidities, higher age and shorter time since surgery were significantly associated with improved HRQL outcomes postoperatively. None of these factors influenced all BODY-Q scales. The effect of current BMI increased with longer time since surgery. CONCLUSION Factors including current BMI, %TWL, employment status, presence of comorbidities, age and time since surgery were associated with HRQL postoperatively. This information may be used to optimize patient-tailored care, improve patient education and underline the importance of long-term follow-up with special attention to weight regain to ensure lasting improvement in HRQL.

Abstract
Self-management interventions (SMIs) can improve the life of patients living with obesity. However, there is variability in the outcomes used to assess the effectiveness of SMIs and these are often not relevant for patients. In the context of COMPAR-EU, our aim was to develop a core outcome set (COS) for the evaluation of SMIs for patients with obesity. We followed a four steps multimethod approach: (1) the development of the initial catalogue of outcomes; (2) a scoping review of reviews on patients' values and preferences on outcomes of self-management (SM); (3) a Delphi survey including patients and patient representatives to rate the importance of outcomes; and (4) a 2-day consensus workshop with patients, patient representatives, healthcare professionals and researchers. The initial catalogue included 82 outcomes. Ten patients and patient's representatives participated in the Delphi survey. We identified 16 themes through the thematic synthesis of the scoping review that informed 37.80% of the outcomes on initial catalogue. Five patients, five healthcare professionals, and four researchers participated in the consensus workshop. After the consensus process, 15 outcomes were selected to be part of the final COS, and five supplementary outcomes were also provided. We developed a COS for the evaluation of SMIs in obesity with a significant involvement of patients and other key stakeholders. This COS will help improving data synthesis and increasing the value of SM research data in healthcare decision making.

Abstract
Objective Patient satisfaction is viewed as essential for a successful outcome of bariatric surgery. Few studies have explored long‐term satisfaction prospectively. This study aimed to examine pre‐ and post‐surgery predictors for satisfaction with follow‐up care, and change in outcome satisfaction from one to 5 years after bariatric surgery. Methods A sample of 210 participants was recruited from a single treatment center. Self‐reported and medical record data regarding mental and somatic health, body image, follow‐up attendance, and weight loss were obtained before, 1 year, and 5 years after surgery. Results Over 90% of the participants were satisfied with the results and treatment 1 year after surgery, while 69% had their outcome expectations fulfilled and 62% were satisfied with the follow‐up 5 years after surgery. A shift from initial satisfaction to unfulfillment of expectations was predicted by baseline body dissatisfaction, greater percentage of weight regain after initial weight loss, and more discomfort from somatic symptoms 5 years after surgery. In addition to symptom discomfort, worry about surgery predicted satisfaction with follow‐up care. Conclusion At 5 years, one‐fifth of those initially satisfied reported that bariatric surgery had failed to meet their expectations. This suggests that outcome expectations related to weight loss, somatic symptoms, and body image need to be addressed both before and after bariatric surgery.

Psychological Aspects of Treatment with Intragastric Balloon for Management of Obesity: A Systematic Review of the Literature. Obes Facts 2022; 15:1-18.

Abstract
INTRODUCTION Optimizing maintenance of weight loss for people with obesity following intragastric balloon (IGB) therapy hinges on the degree to which health care providers can recognize both the impact of emotional problems and mood difficulties on their capacity to self-manage, and requirements for additional support. However, there is limited research on the psychological correlates of IGB therapy. This systematic review, for the first time, attempts to identify and synthesize the empirical evidence for the reciprocal influence between psychological variables and IGB outcomes. METHODS A literature search was performed in the PubMed, SCOPUS, MEDLINE, and Google Scholar databases. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed using rigorous inclusion criteria and screening by at least 2 reviewers. The selected articles were assessed for quality using the Strengthening the Reporting of Observational Studies Epidemiology (STROBE) checklist. Data were extracted to address the review aims and presented as a narrative synthesis. The review protocol was preregistered (Prospero CRD42019121291). RESULTS A total of 16,179 titles, 14,369 abstracts, and 51 full-text articles were screened, of which 16 studies were included. Findings suggest that female gender, older age, basic educational level, and single/divorced civil status, together with lower levels of depression, binge eating, higher perceived quality of life, and motivation to change were predictors of enhanced IGB treatment outcomes. Dissatisfaction with treatment was higher in those with impaired obesity-related social-life difficulties. The IGB treatment was effective in reducing weight and improving depression, anxiety, eating disorder symptoms, and the overall life quality of patients with obesity - mainly within 6 months from the device positioning and in conjunction with conventional therapies. DISCUSSION/CONCLUSION In line with the available literature on obesity and bariatric surgery interventions, poor mental health appears to be an important barrier for successful weight loss among patients with obesity undergoing IGB treatment. In order to improve the efficacy and effectiveness of the IGB therapy, more comprehensive and standardized studies are needed to provide insight into the psychological mechanisms maintaining weight management issues.

Abstract
Gastric bypass surgery leads to significant and sustained weight loss and a reduction in associated health risks in individuals with severe obesity. While reduced energy intake (EI) is the primary driver of weight loss following surgery, the underlying mechanisms accounting for this energy deficit are not well understood. The evidence base has been constrained by a lack of fit-for-purpose methodology in assessing food intake coupled with follow-up studies that are relatively short-term. This paper describes the underlying rationale and protocol for an observational, fully residential study using covert, objective methodology to evaluate changes in 24-hr food intake in patients (n = 31) at 1-month pre-surgery and 3-, 12- and 24-months post-surgery, compared to weight-stable controls (n = 32). The main study endpoints included change in EI, macronutrient intake, food preferences, and eating behaviours (speed, frequency, and duration of eating). Other physiological changes that may influence EI and weight regulation including changes in body composition, circulating appetite hormones, resting metabolic rate, total energy expenditure and gastrointestinal symptoms were also evaluated. Understanding which mechanisms contribute to a reduction in EI and weight loss post-surgery could potentially help to identify those individuals who are most likely to benefit from gastric bypass surgery as well as those that may need more targeted intervention to optimise their weight loss post-surgery. Furthermore, clarification of these mechanisms may also inform targeted approaches for non-surgical treatments of obesity.

Is the RAND-36 an Adequate Patient-reported Outcome Measure to Assess Health-related Quality of Life in Patients Undergoing Bariatric Surgery? Obes Surg 2021; 32:48-54. [PMID: 34729711 PMCID: PMC8752557 DOI: 10.1007/s11695-021-05736-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/01/2021] [Revised: 09/23/2021] [Accepted: 09/24/2021] [Indexed: 11/06/2022]
Abstract
Purpose The RAND-36 is the most frequently used patient-reported outcome measure (PROM) to evaluate health-related quality of life (HRQoL) in bariatric surgery. However, the RAND-36 has never been adequately validated in bariatric surgery. The purpose of this study was to validate the RAND-36 in Dutch patients undergoing bariatric surgery. Material and Methods To validate the RAND-36, the following measurement properties were assessed in bariatric surgery patients: validity (the degree to which the RAND-36 measures what it purports to measure (HRQoL)), reliability (the extent to which the scores of the RAND-36 are the same for repeated measurement for patients who have not changed in HRQoL), responsiveness (the ability of the RAND-36 to detect changes in HRQoL over time). Results Two thousand one hundred thirty-seven patients were included. Validity was not adequate due to the irrelevance of some items and response options, the lack of items relevant to patients undergoing bariatric surgery, and the RAND-36 did not actually measure what it was intended to measure in this study (HRQoL in bariatric surgery patients). Reliability was insufficient for the majority of the scales (the scores of patients who had not changed in HRQoL were different when the RAND was completed a second time (intraclass correlation coefficient (ICC) values 0.10–0.69)). Responsiveness was insufficient. Conclusion The RAND-36 was not supported by sufficient validation evidence in patients undergoing bariatric surgery, which means that the RAND-36 does not adequately measure HRQoL in this patient population. Future research studies should use PROMs that are specifically designed for assessing HRQoL in patients undergoing bariatric surgery. Graphical abstract ![]()

Abstract
The Impact of Weight on Quality of Life-Lite Clinical Trials Version (IWQOL-Lite-CT) was developed to assess weight-related physical and psychosocial functioning in the context of clinical trials. Data from two pivotal trials of once-weekly subcutaneous semaglutide for the purpose of weight management (NCT03548935 and NCT03552757) were analysed to confirm the structure, reliability, validity, and responsiveness of the IWQOL-Lite-CT and evaluate the magnitude of meaningful within-patient change in patients with overweight or obesity, with and without type 2 diabetes. Factor analyses and inter-item correlations confirmed the IWQOL-Lite-CT structure and scoring algorithm. Each composite score (physical, physical function, psychosocial, and total) demonstrated excellent internal consistency (Cronbach's alphas ≥ 0.82) and test-retest reliability (intraclass correlation coefficients ≥ 0.85) in both trials. Patterns of cross-sectional and longitudinal construct validity correlations were generally consistent with hypotheses. Each of the IWQOL-Lite-CT composites was able to discriminate between known groups. Effect sizes and paired t tests comparing IWQOL-Lite-CT scores at baseline and Week 68 were statistically significant for all composites in both trials (P < 0.0001), providing strong support for the ability to detect change. Results of anchor-based analyses supported responder thresholds ranging from 13.5 to 16.6 across composite scores. The IWQOL-Lite-CT, a comprehensive assessment of weight-related functioning from the patient perspective, is appropriate for use in clinical trials evaluating the efficacy of new treatments for weight management.

Abstract
Gastric bypass surgery is an effective long-term treatment for individuals with severe obesity. Changes in appetite, dietary intake, and food preferences have all been postulated to contribute to postoperative body weight regulation, however, findings are inconsistent. The aim of this systematic review was to evaluate the current literature on changes in dietary intake and appetite following gastric bypass surgery, in the context of the methodology used and the analysis, interpretation, and presentation of results. Four databases were systematically searched with terms related to "gastric bypass surgery," "appetite," and "dietary intake," and 49 papers (n = 2384 patients after gastric bypass) were eligible for inclusion. The evidence indicated that only a reduction in overall energy intake and an increase in postprandial satiety are maintained beyond 6-month post-surgery, whereas relative macronutrient intake and premeal hunger remain unchanged. However, available data were limited by inconsistencies in the methods, analysis, presentation, and interpretation of results. In particular, there was a reliance on data collected by subjective methods with minimal acknowledgment of the limitations, such as misreporting of food intake. There is a need for further work employing objective measurement of appetite and dietary intake following gastric bypass surgery to determine how these mechanisms may contribute to weight regulation in the longer term.

Abstract
PURPOSE The BODY-Q is a rigorously developed patient-reported outcome measure (PROM) for patients seeking treatment for obesity and body contouring surgery. A limitation of the uptake of the BODY-Q in weight management treatments is the absence of scales designed to measure eating-specific concerns. We aimed to develop and validate 5 new BODY-Q scales measuring weight loss expectations, eating behaviors, distress, symptoms, and work life. MATERIAL AND METHODS In phase 1 (qualitative), patient and expert input was used to develop and refine the new BODY-Q scales. In phase 2 (quantitative), the scales were field-tested in bariatric and weight management clinics in the United States (US), The Netherlands, and Denmark between June 2019 and January 2020. Data were also collected in the US and Canada in September 2019 through a crowdworking platform. Rasch measurement theory (RMT) analysis was used for item reduction and to examine reliability and validity. RESULTS The new BODY-Q scales were refined through qualitative input from 17 patients and 20 experts (phase 1) and field-tested in 4004 participants (phase 2). All items showed ordered thresholds and good fit to the Rasch model. The RMT analysis provided evidence of reliability, with PSI values ≥0.72, Cronbach alpha values ≥0.83, and test-retest values ≥0.79. Better scores on 4 scales (exception expectations scale) correlated with lower BMI, with the strongest correlation between the eating-related distress scale scores and BMI (r= -0.249, P < 0.001). CONCLUSION The new BODY-Q scales can be used in research and clinical practice to assess weight loss treatments from the patient perspective.

Abstract
PURPOSE Although the post-bariatric clinical and physical changes are well-known, the psychosocial changes in patients' everyday life are less clear. Therefore, we tried to summarize comprehensively the currently available literature on the psychosocial changes of bariatric surgery (BS) by means of a scoping review. MATERIALS AND METHODS The scoping review was conducted following the Arksey and O'Malley framework, the Joanna Briggs Institute Reviewer's Manual 2015, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) checklist. PubMed, EMBASE, and PsycINFO were searched for data dating from January 2008 through October 2019. Only gastric bypass and sleeve gastrectomy procedures were considered for this review. To explore and describe the essence of the experienced changes deeply, only qualitative studies were included. The synthesis was performed using the qualitative content analysis technique. RESULTS The literature search yielded 1420 unique records, and 1371 articles were eliminated on the basis of irrelevant title and/or abstract. Forty-nine full-text articles were reviewed. Ultimately, eight articles were included in this scoping review. The qualitative content analysis emerged in 12 categories, which were further condensed into three major thematic areas, namely, "subjective self-image," "interpersonal relationships," and "it's not all gold that glitters," which reflect the post-operative psychosocial changes. CONCLUSION A wide range of psychosocial changes occurs following bariatric surgery. To maintain the improvements and to prevent negative changes, long-term support by specially trained health professionals is crucial.

Abstract
PURPOSE This study aimed to assess bariatric surgery (BS) effect on fall risk factors. MATERIALS AND METHODS Fifteen patients undergoing BS (intervention group, IG) and 10 non-surgical obese patients (control group, CG) were recruited. IG was assessed at pre-surgery and 6 months after BS, while CG was assessed at baseline and reassessed after 6 months. At both time-points, anthropometry, lower limbs muscle strength (isokinetic dynamometer), balance in bipedal stance (force platform), daily physical activity (accelerometry), and health-related quality of life (SF-36 questionnaire) were assessed. RESULTS At baseline, there were no differences between CG and IG for all parameters analyzed. Compared to CG, 6 months post-BS, the IG decreased weight, body mass index, waist and hip circumference. Balance showed limited improvements, with gains observed only on antero-posterior and total center of pressure velocity. Muscle strength displayed a divergent evolution 6 months after BS, with a decrease in absolute strength but an increase in relative strength. Although BS did not induce significant changes in time spent in different physical activity intensities, it decreased time in sedentary behavior and increased number of daily steps. Post-BS patients reported substantial improvements in quality-of-life, especially in physical function. CONCLUSION Patients seem to overestimate their actual physical fitness improvements attained after BS, which combined with increases in physical activity, might increase the likelihood of engaging in risky daily tasks to what they are physically not prepared to, consequently increasing fall risk.

Abstract
Interventions from randomised controlled trials can only be replicated if they are reported in sufficient detail. The results of trials can only be confidently interpreted if the delivery of the intervention was systematic and the protocol adhered to. We systematically reviewed trials of anaesthetic interventions published in 12 journals from January 2016 to September 2019. We assessed the detail with which interventions were reported, using the Consolidated Standards of Reporting Trials statement for non‐pharmacological treatments. We analysed 162 interventions reported by 78 trials in 18,675 participants. Detail sufficiently precise to replicate the intervention was reported for 111 (69%) interventions. Intervention standardisation was reported for 135 (83%) out of the 162 interventions, and protocol adherence was reported for 20 (12%) interventions. Sixty (77%) out of the 78 trials reported the administrative context in which interventions were delivered and 36 (46%) trials detailed the expertise of the practitioners. We conclude that bespoke reporting tools should be developed for anaesthetic interventions and interventions in other areas such as critical care.

Surg Obes Relat Dis 2020; 17:538-547. [PMID: 33334677 DOI: 10.1016/j.soard.2020.10.028] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Revised: 08/05/2020] [Accepted: 10/25/2020] [Indexed: 11/17/2022]
Abstract
BACKGROUND Patient-reported outcomes (PRO) obtained from follow-up survey data are essential to understanding the longitudinal effects of bariatric surgery. However, capturing data among patients who are well beyond the recovery period of surgery remains a challenge, and little is known about what factors may influence follow-up rates for PRO. OBJECTIVES To assess the effect of hospital practices and surgical outcomes on patient survey completion rates at 1 year after bariatric surgery. SETTING Prospective, statewide, bariatric-specific clinical registry. METHODS Patients at hospitals participating in the Michigan Bariatric Surgery Collaborative are surveyed annually to obtain information on weight loss, medication use, satisfaction, body image, and quality of life following bariatric surgery. Hospital program coordinators were surveyed in June 2017 about their practices for ensuring survey completion among their patients. Hospitals were ranked based on 1-year patient survey completion rates between 2011 and 2015. Multivariable regression analyses were used to identify associations between hospital practices, as well as 30-day outcomes, on hospital survey completion rankings. RESULTS Overall, patient survey completion rates at 1 year improved from 2011 (33.9% ± 14.5%) to 2015 (51.0% ± 13.0%), although there was wide variability between hospitals (21.1% versus 77.3% in 2015). Hospitals in the bottom quartile for survey completion rates had higher adjusted rates of 30-day severe complications (2.6% versus 1.7%, respectively; P = .0481), readmissions (5.0% versus 3.9%, respectively; P = .0157), and reoperations (1.5% versus .7%, respectively; P = .0216) than those in the top quartile. While most hospital practices did not significantly impact survey completion at 1 year, physically handing out surveys during clinic visits was independently associated with higher completion rates (odds ratio, 13.60; 95% confidence interval, 1.99-93.03; P =.0078). CONCLUSIONS Hospitals vary considerably in completion rates of patient surveys at 1 year after bariatric surgery, and lower rates were associated with hospitals that had higher complication rates. Hospitals with the highest completion rates were more likely to physically hand surveys to patients during clinic visits. Given the value of PRO on longitudinal outcomes of bariatric surgery, improving data collection across multiple hospital systems is imperative.

Abstract
PURPOSE OF REVIEW This review describes the latest evidence for the impact of bariatric surgery on health-related quality of life (HRQL). RECENT FINDINGS The impact of bariatric surgery on HRQL is less well-understood than its clinical effectiveness on weight and co-morbidities. Poor-quality study design and different HRQL measures challenge systematic reviews and meta-analyses. Available limited evidence suggests that physical aspects of HRQL may improve more than mental health aspects of HRQL after bariatric surgery, reaching maximal benefits 1-2 years post-surgery. Comparative HRQL analyses between bariatric procedures cannot be made due to a lack of randomised data. Qualitative research highlights the tensions patients experience after bariatric surgery, which provides insights to observed changes in HRQL. Standardized HRQL measures are being developed and agreed to improve future evidence synthesis. Two multi-centre randomised trials of bariatric surgical procedures including detailed HRQL assessment are in progress. It is hoped that the combination of comparative high-quality HRQL data and information from qualitative studies will provide new insights into patient well-being and health after bariatric surgery.

Abstract
Health state utilities (HSUs) are health economic metrics that capture and assess health-related quality of life (HRQoL). They are essential in health-economic evaluations when calculating quality-adjusted life years. We investigated published studies reporting bariatric surgery-related HSUs elicited through direct or indirect (multiattribute utility instrument [MAUI]) patient-reported methods (PROSPERO registration number: CRD42019131725). Mean HSUs for different time points and HSU changes over time (where feasible) were meta-analysed using random-effects models. Of the 950 potentially relevant identified studies, n = 28 (2004-2018) qualified for data extraction, with n = 85 unique HSUs elicited mainly from the EQ-5D (88%). Most (75%) studies were published after 2013. The follow-up duration varied between studies and was often limited to 12 months. The pooled mean HSU was 0.72 (0.67-0.76) at baseline/presurgery (n = 18) and 0.84 (0.79-0.89) one-year postsurgery (n = 11), indicating a 0.11 (0.09-0.14) utility unit increment. EQ-5D showed the similar results. This positive difference can be partially explained by BMI and/or co-morbidities status improvement. This study provides a valuable summary of HSUs to future bariatric surgery-related cost-utility models. However, more well-designed higher-quality bariatric-related HSU studies are expected for future reviews to improve the available evidence. We suggest that researchers select an MAUI that is preferentially sensitive to the study population.

Abstract
OBJECTIVE The aim of this study was to compare the use and short-term outcome of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) in Sweden, Norway, and the Netherlands. BACKGROUND Although bariatric surgery is performed in high volumes worldwide, no consensus exists regarding the choice of bariatric procedure for specific groups of patients. METHODS Data from 3 national registries for bariatric surgery were used. Patient selection, perioperative data (severe complications, mortality, and rate of readmissions within 30 days), and 1-year results (follow-up rate and weight loss) were studied. RESULTS A total of 47,101 primary operations were registered, 33,029 (70.1%) RYGB and 14,072 (29.9%) SG. Patients receiving RYGB met international guidelines for having bariatric surgery more often than those receiving SG (91.9% vs 83,0%, P < 0.001). The 2 procedures did not differ in the rate of severe complications (2.6% vs 2.4%, P = 0.382), nor 30-day mortality (0.04% vs 0.03%, P = 0.821). Readmission rates were higher after RYGB (4.3% vs 3.4%, P < 0.001).One-year post surgery, less RYGB-patients were lost-to follow-up (12.1% vs 16.5%, P < 0.001) and RYGB resulted in a higher rate of patients with total weight loss of more than 20% (95.8% vs 84.6%, P < 0.001). While the weight-loss after RYGB was similar between hospitals, there was a great variation in weight loss after SG. CONCLUSION This study reflects the pragmatic use and short-term outcome of RYGB and SG in 3 countries in North-Western Europe. Both procedures were safe, with RYGB having higher weight loss and follow-up rates at the cost of a slightly higher 30-day readmission rate.

Abstract
PURPOSE Sleeve gastrectomy (SG) is the most popular type of bariatric surgery. It has often been compared to Roux-en-Y gastric bypass (RYGB) in terms of clinical outcomes. However, health-related quality of life (HRQoL) has been sparsely studied after SG. The goal was to study HRQoL after SG using a generic (RAND-36) and an obesity-specific (impact of weight on quality of life-lite, IWQOL-lite) questionnaire and to compare the results with RYGB. METHODS HRQoL and weight were measured before and 9, 15, and 24 months after surgery. RAND-36 physical health summary (PHS) and mental health summary (MHS), and IWQOL-lite total score were calculated. A mixed model analysis was conducted to study the change in HRQoL and compare SG with RYGB. RESULTS A total of 219 patients (8.7%) underwent a SG and 2309 patients (91.3%) a RYGB. PHS, MHS, and IWQOL-lite significantly improved after SG when comparing baseline to all follow-up moments (p < 0.001 in all). There were no significant differences when comparing SG with RYGB: change in PHS (β - 0.10, 95% CI - 1.24 to 1.04, p = 0.861), MHS (β - 0.51, 95% CI - 1.56 to 0.52, p = 0.330), and IWQOL-lite (β 0.310, 95% CI - 0.85 to 1.47, p = 0.601). CONCLUSION HRQoL significantly improved after SG. In the included populations, weight loss was comparable and the extent to which HRQoL improved did not differ between SG and RYGB, when measured with the RAND-36 or IWQOL-lite. This might be partly caused by the fact that these questionnaires do not assess specific bariatric HRQoL and/or complaints.

Abstract
Weight loss is the primary outcome following bariatric surgery; however, its documentation within current literature is heterogeneous and poorly defined, limiting meaningful comparison between studies. Randomized controlled trials from 2012 to 2016 were identified using the Medline database through "Gastric bypass OR sleeve gastrectomy AND weight" search terms. A total of 73 studies with 5948 patients were included. Reporting of preoperative weight was done primarily using mean body mass index (BMI) (87.7%) and mean weight (65.8%). Postoperative weight reporting was more variable, with the most frequently reported measure being mean postoperative BMI (71.2%). Overall, nearly one third of all bariatric literature contained discrepancies that precluded meaningful meta-analysis. Reporting of weight loss following bariatric surgery is becoming increasingly diverse for both pre- and post-operative outcomes. Ongoing heterogeneity will continue to act as a barrier to meaningful comparison of bariatric outcomes until standardized reporting practices become adopted.

Abstract
OBJECTIVES Bariatric surgery is the most clinically effective treatment for people with severe and complex obesity, however, the psychosocial outcomes are less clear. Follow-up care after bariatric surgery is known to be important, but limited guidance exists on what this should entail, particularly related to psychological and social well-being. Patients' perspectives are valuable to inform the design of follow-up care. This study investigated patients' experiences of life after bariatric surgery including important aspects of follow-up care, in the long term. DESIGN A qualitative study using semistructured individual interviews. A constant comparative approach was used to code data and identify themes and overarching concepts. SETTING Bariatric surgery units of two publicly funded hospitals in the South of England. PARTICIPANTS Seventeen adults (10 women) who underwent a primary operation for obesity (mean time since surgery 3.11 years, range 4 months to 9 years), including Roux-en-Y gastric bypass, adjustable gastric band and sleeve gastrectomy, agreed to participate in the interviews. RESULTS Experiences of adapting to life following surgery were characterised by the concepts of 'normality' and 'ambivalence', while experiences of 'abandonment' and 'isolation' dominated participants' experiences of follow-up care. Patients highlighted the need for more flexible, longer-term follow-up care that addresses social and psychological difficulties postsurgery and integrates peer support. CONCLUSIONS This research highlights unmet patient need for more accessible and holistic follow-up care that addresses the long-term multidimensional impact of bariatric surgery. Future research should investigate effective and acceptable follow-up care packages for patients undergoing bariatric surgery.

Measuring quality of life in bariatric surgery: a multicentre study. Surg Endosc 2020; 34:5522-5532. [PMID: 31993820 PMCID: PMC7644534 DOI: 10.1007/s00464-019-07350-4] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2019] [Accepted: 12/24/2019] [Indexed: 01/05/2023]
Abstract
BACKGROUND Current studies mainly focus on total weight loss and comorbidity reduction. Only a few studies compare Quality of Life (QoL) after sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB). This study was conducted to examine the extent of improvement in QoL on different domains after primary bariatric surgery and compare these results to Dutch reference values. METHODS The study included prospectively collected data from patients who underwent primary bariatric surgery in five Dutch hospitals. The RAND-36 questionnaire was used to measure the patient's QoL; preoperatively and twelve months postoperatively. Postoperative scores were compared to Dutch reference values, standardized for age, using t-test. A difference of more than 5% was considered a minimal important difference. A multivariate linear regression analysis was used to compare SG and RYGB on the extent of improvement, adjusted for case-mix factors. RESULTS In total, 4864 patients completed both the pre- and postoperative questionnaire. Compared with Dutch reference values, patients postoperatively reported clinically relevant better physical functioning (RYGB + 6.8%), physical role limitations (SG + 5.6%; RYGB + 6.2%) and health change (SG + 77.1%; RYGB + 80.0%), but worse general health perception (SG - 22.8%; RYGB - 17.0%). Improvement in QoL was similar between SG and RYGB, except for physical functioning (β 2.758; p-value 0.008) and general health perception (β 2.607; p-value < 0.001) for which RYGB patients improved more. CONCLUSIONS SG and RYGB patients achieved a better postoperative score in physical functioning, physical role limitations and health change compared to Dutch reference values, and a worse score in general health perception.

Abstract
Bariatric surgery is the most effective treatment for weight loss in individuals with severe and complex obesity. While the extant literature has mostly explored clinical outcomes of surgery, recent research has also examined patients' experiences prior to treatment. This systematic review synthesized findings from qualitative studies investigating patients' motives and expectations prior to undergoing bariatric surgery for weight loss. Twenty-eight studies published in English involving 580 participants were identified for inclusion. Data extraction and thematic synthesis yielded four global themes: physiological, emotional, cognitive, and interpersonal/environmental. These represented seven subthemes describing patients' presurgery experiences: relationship with food, physical health, activities of living, personal identity, social relations, presurgery information, and beliefs about surgery. In addition to improving physical and medical comorbidities associated with obesity, participants believed that postsurgery weight loss would produce positive psychosocial impacts by strengthening their personal identities, their relationships, and improving their engagement in public and professional life. The complex and widespread nature of the changes patients expected would result from bariatric surgery highlights the importance of providing pretreatment education focused on psychosocial well-being, as well as concurrent psychological support alongside surgery, to best inform individual treatment selection and clinical practice.

Abstract
BACKGROUND Choice of a multi-attribute utility instrument (MAUI) that appropriately assesses an intervention's health-related quality-of-life (HRQoL) impacts is a vital part of healthcare resource allocation and clinical assessment. OBJECTIVE Our exploratory study compared the EuroQol (EQ)-5D-5L and Assessment of Quality of Life (AQoL)-8D MAUIs, which were used to assess the effect of bariatric surgery for a cohort of long-term publicly waitlisted, severely obese patients. METHODS The study was conducted at the Hobart Private Hospital (Tasmania, Australia). To compare the sensitivity and instrument content of the two MAUIs, we used dimensional comparisons by investigating the distribution of patient-reported responses (number/percentage) across the MAUIs' levels and dimensions; summary health-state utility valuations (utilities); and individual/super-dimension scores (AQoL-8D) to investigate discriminatory power and HRQoL improvements preoperatively and 3 months postoperatively. RESULTS Participants' (n = 23) overall MAUI completion rate was 74%. Postoperative total weight loss was 9.9%. EQ-5D-5L utilities were relatively higher pre- and postoperatively than AQoL-8D utilities [mean standard deviation (SD) EQ-5D-5L 0.70 (0.25) to 0.80 (0.25); AQoL-8D 0.51 (0.24) to 0.61 (0.24)]. AQoL-8D Psychosocial super dimension was relatively low postoperatively [0.37 (0.25)], driving the instrument's lower utility. These results were supported by the dimensional comparisons that revealed an overall greater dispersion for the AQoL-8D. Nevertheless, there were clinical improvements in utilities for both instruments. AQoL-8D utilities were lower than population norms; not so the EQ-5D-5L utilities. The AQoL-8D dimensions of Happiness, Coping, and Self-worth improved the most. CONCLUSIONS AQoL-8D more fully captured the impact of obesity and bariatric surgery on HRQoL (particularly psychosocial impacts) for long-term waitlisted bariatric surgery patients, even 3 months postoperatively. AQoL-8D preoperative utility revealed our population's HRQoL was lower than people with cancer or heart disease.

Abstract
OBJECTIVE The objective of this study is to systematically assess the quality of existing patient-reported outcome measures developed and/or validated for Quality of Life measurement in bariatric surgery (BS) and body contouring surgery (BCS). METHODS We conducted a systematic literature search in PubMed, EMBASE, PsycINFO, CINAHL, Cochrane Database Systematic Reviews and CENTRAL identifying studies on measurement properties of BS and BCS Quality of Life instruments. For all eligible studies, we evaluated the methodological quality of the studies by using the COnsensus-based Standards for the selection of health Measurement INstruments checklist and the quality of the measurement instruments by applying quality criteria. Four degrees of recommendation were assigned to validated instruments (A-D). RESULTS Out of 4,354 articles, a total of 26 articles describing 24 instruments were included. No instrument met all requirements (category A). Seven instruments have the potential to be recommended depending on further validation studies (category B). Of these seven, the BODY-Q has the strongest evidence for content validity in BS and BCS. Two instruments had poor quality in at least one required quality criterion (category C). Fifteen instruments were minimally validated (category D). CONCLUSION The BODY-Q, developed for BS and BCS, possessed the strongest evidence for quality of measurement properties and has the potential to be recommended in future clinical trials.

Abstract
BACKGROUND Excess visceral adipose tissue has been identified as an important risk factor for obesity-related co-morbidities. Conflicting information exists on whether omentectomy added to bariatric surgery is beneficial to metabolic variables. OBJECTIVE To evaluate the impact of omentectomy added to bariatric surgery on metabolic outcomes SETTING: University Hospital, Canada. METHODS MEDLINE, EMBASE, and PubMed were searched up to May 2018. Studies were eligible for inclusion if they were randomized controlled trials comparing omentectomy added to bariatric surgery with bariatric surgery alone. Primary outcome measures were absolute change in metabolic variables (body mass index, insulin, glucose, cholesterol, lipoproteins, and triglycerides); secondary outcomes were changes in adipocytokines. Pooled mean differences (mean deviation; MD) were calculated using random effects meta-analyses, and heterogeneity was quantified using the I2 statistic. RESULTS Ten trials involving a total of 366 patients met the inclusion criteria with a median follow-up time of 1 year after surgery. Adding omentectomy to bariatric surgery demonstrated a minimal but statistically significant decrease in body mass index compared with bariatric surgery alone (MD 1.29, 95% confidence interval .35-2.23, P = .007, I2 = 0%, 10 trials). Conversely, patients who underwent bariatric surgery alone had significant increases in high-density lipoprotein (MD -2.12, 95% confidence interval -4.13 to -.11, P = .04, I2 = 0%, 6 trials). Other metabolic outcomes and adipocytokines showed no significant difference between procedures. CONCLUSION The addition of omentectomy to bariatric surgery results in minimal reduction of body mass index. Considering no overall improvement in metabolic outcomes and the time and effort required, the therapeutic use of omentectomy added to bariatric surgery is not warranted.

Abstract
INTRODUCTION In the Netherlands, the number of bariatric procedures increased exponentially in the 90s. To ensure and improve the quality of bariatric surgery, the nationwide Dutch Audit for Treatment of Obesity (DATO) was established in 2014. The audit was coordinated by the Dutch Institute for Clinical Auditing (DICA). This article provides a review of the aforementioned process in establishing a nationwide registry in the Netherlands. MATERIALS AND METHODS In collaboration with the DATO's scientific committee and other stakeholders, an annual list of several external quality indicators was formulated. This list consists of volume, process, and outcome indicators. In addition to the annual external indicators, the database permits individual hospitals to analyze their own data. The dashboard provides several standardized reports and detailed quality indicators, which are updated on a weekly base. RESULTS Since the start, all 18 Dutch bariatric centers participated in the nationwide audit. A total of 21,941 cases were registered between 2015 and 2016. By 2016, the required variables were registered in 94.3% of all cases. A severe complicated course was seen in 2.87%, and mortality in 0.05% in 2016. The first-year follow-up shows a > 20% TWL in 86.1% of the registered cases. DISCUSSION The DATO has become rapidly a mature registry. The well-organized structure of the national audit institution DICA and governmental funding were essential. However, most important were the bariatric teams themselves. The authors believe reporting the results from the registry has already contributed to more knowledge and acceptance by other health care providers.

Abstract
BACKGROUND Following weight-loss surgery, patients who failed to achieve or sustain weight loss have nevertheless reported high satisfaction with their long-term bariatric experience. Understanding this phenomenon better will likely improve patients' experiences. OBJECTIVE The purpose of this study was to explore patients' long-term experiences following bariatric surgery. SETTING A 604-bed academic health system in the USA. METHODS Participants rated satisfaction and shared spontaneous comments regarding their gastric bypass experience. A phenomenological mode of inquiry explored participants' experiences. Transcribed phrases were categorized and themes identified. RESULTS In a 2004 surgical cohort, with 55% (155/281) participation, 99% of participants rated bariatric experience satisfaction (mean score 8.4) and 74% (115/155) shared comments regarding experiences. Responses were categorized as positive (63% 72/115), neutral (25% 29/115), or negative (12% 14/115). Satisfaction, Appreciation, and Gratefulness emerged as themes from positive comments, with 8% (6/72) explicitly acknowledging amount of weight loss achieved. Twenty-five percent (18/72) spontaneously mentioned undergoing surgery again or recommending the procedure to others. Neutral comments contained the themes of Reflection, Acknowledgment, and Wistfulness. Themes of Dissatisfaction, Disappointment, and Regret emerged from negative comments. Forty-three percent (6/14) of negative comments remarked on regaining weight or not reaching goal weight. Twenty-one percent (3/14) of negative comments explicitly stated regret at having undergone surgery. CONCLUSIONS Participants readily shared comments regarding their gastric bypass experience. Exploring themes provided insight into patients' satisfaction with bariatric surgery even when weight-loss goals were not met and conversely substantial dissatisfaction even when weight loss occurred. This study underscores the importance of understanding the patients' long-term experience following bariatric surgery.

Abstract
Bariatric surgery is considered an effective treatment for individuals with severe and complex obesity. Besides reducing weight and improving obesity related comorbidities such as diabetes, bariatric surgery could improve patients' health-related quality of life. However, the frequently used instrument to measure quality of life, the EQ-5D has not been validated for use in bariatric surgery, which is a major limitation to its use in this clinical context. Our study undertook a psychometric validation of the 5 level EQ-5D (EQ-5D-5L) using clinical trial data to measure health-related quality of life in patients with severe and complex obesity undergoing bariatric surgery. Health-related quality of life was assessed at baseline (before randomisation) and six months later in 189 patients in a randomised controlled trial of bariatric surgery. Patients completed two generic health-related quality of life instruments, the EQ-5D-5L and SF-12, which were used together for the validation using data from all patients in the trial as the trial is ongoing. Psychometric analyses included construct and criterion validity and responsiveness to change. Of the 189 validation patients, 141 (75%) were female, the median age was 49 years old (range 23-70 years) and body mass index ranged from 33-70 kg/m2. For construct validity, there were significant improvements in the distribution of responses in all EQ-5D dimensions between baseline and 6 months after randomisation. For criterion validity, the highest degree of correlation was between the EQ-5D pain/discomfort and SF-12 bodily pain domain. For responsiveness the EQ-5D and SF-12 showed statistically significant improvements in health-related quality of life between baseline and 6 months after randomisation. The EQ-5D-5L is a valid generic measure for measuring health-related quality of life in bariatric surgery patients.

Abstract
An expert committee was appointed by the German Society for General and Visceral Surgery to develop a panel of appropriate quality indicators to collate the quality of results, indications and structure in metabolic and bariatric surgery. This entailed assimilating the available evidence (systematic literature search), results from the national registry of the society (StuDoQ|MBE) and specific socioeconomic aspects (e. g. severely limited access to metabolic and bariatric surgery in Germany). These quality parameters were to be incorporated into the national guidelines and the rules of procedure for certification in the future. The committee concluded that mortality, MTL30 and severe complications needing intervention (Clavien-Dindo ≥ 3b) are suitable indicators to measure surgical outcome quality due to their relevance, scientific soundness and practicability. As a systematic follow-up is mandatory after bariatric surgery, a minimum follow-up quota is now required using reported quality of life data as an indicator of process quality. As intestinal bypass procedures have been shown to be superior in the treatment of type 2 diabetes, these procedures should be offered to eligible patients and also be performed. The proposed threshold values based on the results of the available literature and StuDoQ registry are to be considered as preliminary and need to be validated and adjusted if necessary in the future. The StuDoQ|MBE is considered a valuable tool to gather this information and also represents the appropriate infrastructure for the collation of relevant risk adjustors.

Abstract
PURPOSE OF REVIEW The purpose of this review is to provide an introduction to quality of life (QOL) outcomes after bariatric surgery and a summary of the current evidence. RECENT FINDINGS QOL has been emphasized in bariatric surgery since the NIH Consensus Conference statement in 1991. Initial studies were limited to 1- and 2-year follow-up. More recent findings have expanded the follow-up period up to 12 years, providing a better description of the impact on long-term QOL. Overall, there is little to no consensus regarding the definition of QOL or the ideal survey. Bariatric surgery has the greatest impact on physical QOL, and the impact on mental health remains unclear. There are some specific and less frequently reported threats to quality of life after bariatric surgery that are also discussed. Obesity has a definite impact on quality of life, even without other comorbidities, and surgery for obesity results in significant and lasting improvements in patient-reported quality of life outcomes. This conclusion is limited by a wide variety of survey instruments and absence of consensus on the definition of QOL after bariatric surgery.

Although bariatric surgery is the most effective treatment for severe and complex obesity, less is known about its psychosocial impact. This systematic review synthesizes qualitative studies investigating the patient perspective of living with the outcomes of surgery. A total of 2,604 records were screened, and 33 studies were included. Data extraction and thematic synthesis yielded three overarching themes: control, normality and ambivalence. These were evident across eight organizing sub-themes describing areas of life impacted by surgery: weight, activities of daily living, physical health, psychological health, social relations, sexual life, body image and eating behaviour and relationship with food. Throughout all these areas, patients were striving for control and normality. Many of the changes experienced were positive and led to feeling more in control and 'normal'. Negative changes were also experienced, as well as changes that were neither positive nor negative but were nonetheless challenging and required adaptation. Thus, participants continued to strive for control and normality in some aspects of their lives for a considerable time, contributing to a sense of ambivalence in accounts of life after surgery. These findings demonstrate the importance of long-term support, particularly psychological and dietary, to help people negotiate these challenges and maintain positive changes achieved after bariatric surgery.

Abstract
Highlights Quality-of-life measures improve as early as 3 months after bariatric surgery.There is wide variability in reporting that renders direct comparisons difficult.The available comparisons between RYGB and sleeve gastrectomy could not detect any difference.Improvement in PRO measures might be related to weight loss.Larger and better designed studies are required to achieve discrimination in PRO measures. Background Obesity is associated with reduced quality-of-life (QoL), which generally improves after bariatric surgery. The differential effect of each type of surgery (gastric sleeve [SG] and gastric bypass [RYGB]) on QoL is not yet fully understood. Objectives To understand which of these surgeries offers greatest improvement in QoL and patient satisfaction. Methods Systematic literature search on Pubmed in July 2014. Relevant articles were selected in a step-wise approach. The 2482 titles were scanned for relevance and 191 were selected for abstract reviewing; and 88 papers were selected for full text analysis. Results Only 5 papers compared the 2 techniques and only 17 more had retrievable data either on SG or RYGB. The reports were very heterogeneous, preventing a direct comparison of patient reported outcomes (PRO) among studies.Improved results have been reported as early has 3 months and SF-36 scores were improved in all domains in medium to long-term. The question remains whether the improvement in QoL is related to the weight loss and which factors are associated with improved patients' perceptions. Conclusions There is wide heterogeneity in the reporting of PRO measures after bariatric surgery, but data is consistent with a significant improvement after both surgeries.Larger and better-designed studies are required to understand if there are significant differences in the quality of life after SG or RYGB.

Quality of life and bariatric surgery: a systematic review of short- and long-term results and comparison with community norms. Eur J Clin Nutr 2016; 71:441-449.

Abstract
Currently the effects of bariatric surgery are generally expressed in excess weight loss or comorbidity reduction. Therefore the aim of this review was to provide insight in the available prospective evidence regarding the short and long-term effects of bariatric surgery on Quality of Life (QoL) and a comparison with community norms. A systematic multi-database search was conducted for 'QoL' and 'Bariatric surgery'. Only prospective studies with QoL before and after bariatric surgery were included. The 'Quality Assessment Tool for Before-After Studies with No Control Group' was used to assess the methodological quality. Thirty-six studies met the inclusion criteria. Most studies were assessed to be of 'fair' to 'good' methodological quality. Ten different questionnaires were used to measure QoL. Follow-up ranged from 6 months to 10 years, sample sizes from 26 to 1276 and follow-up rates from 45 to 100%. A significant increase in QoL after bariatric surgery was found in all studies (P⩽0.05), however, mostly these outcomes stay below community norms. Only outcomes of the IWQoL, SF-36 and OWQoL show QoL outcomes that exceed community norms. The QoL is increased after bariatric surgery on both the short and long term. However, due to the heterogeneity of the studies and the generality of the questionnaires is it hard to make a distinction between different surgeries and difficult to see a relation with medical profit. Therefore, tailoring QoL measurements to the bariatric population is recommended as the focus of future studies.

Abstract
BACKGROUND A comprehensive evaluation of bariatric surgery is required to inform decision-making. This will include measures of benefit and risk. It is possible that stakeholders involved with surgery value these outcomes differently, although this has not previously been explored. This study aimed to investigate and compare how professionals and patients prioritise outcomes of bariatric surgery. METHODS Systematic reviews and qualitative interviews created an exhaustive list of outcomes. This informed the development of a 130-item questionnaire, structured in four sections (complications of surgery; clinical effectiveness; signs, symptoms, and other measures; quality of life). Health professionals and patients rated the importance of each item on a 1-9 scale. Items rated 8-9 by at least 70 % of the participants were considered prioritised. Items prioritised in each section were compared between professionals and patients and interrater agreement assessed using kappa statistics (ĸ). RESULTS One hundred sixty-eight out of four hundred fifty-nine professionals (36.6 %) and 90/465 patients (19.4 %) completed the questionnaire. Professionals and patients prioritised 18 and 25 items, respectively, with 10 overlapping items and 23 discordant items (ĸ 0.363). Examples of items prioritised by both included 'diabetes' and 'leakage from bowel joins'. Examples of discordant items included 're-admission rates' (professionals only) and 'excess skin' (patients only). Poor agreement was seen in the 'quality of life' section (0 overlapping items, 8 discordant, ĸ -0.036). CONCLUSIONS Although there was some overlap of outcomes prioritised by professionals and patients, there were important differences. We recommend that the views of all relevant health professionals and patients are considered when deciding on outcomes to evaluate bariatric surgery.

Abstract
BACKGROUND Bariatric and metabolic surgery is used as a treatment for patients with severe and complex obesity. However, there is a need to improve outcome selection and reporting in bariatric surgery trials. A Core Outcome Set (COS), an agreed minimum set of outcomes reported in all studies of a specific condition, may achieve this. Here, we present the development of a COS for BARIAtric and metabolic surgery Clinical Trials-the BARIACT Study. METHODS AND FINDINGS Outcomes identified from systematic reviews and patient interviews informed a questionnaire survey. Patients and health professionals were surveyed three times and asked to rate the importance of each item on a 1-9 scale. Delphi methods provided anonymised feedback to participants. Items not meeting predefined criteria were discarded between rounds. Remaining items were discussed at consensus meetings, held separately with patients and professionals, where the COS was agreed. Data sources identified 2,990 outcomes, which were used to develop a 130-item questionnaire. Round 1 response rates were moderate but subsequently improved to above 75% for other rounds. After rounds 2 and 3, 81 and 14 items were discarded, respectively, leaving 35 items for discussion at consensus meetings. The final COS included nine items: "weight," "diabetes status," "cardiovascular risk," "overall quality of life (QOL)," "mortality," "technical complications of the specific operation," "any re-operation/re-intervention," "dysphagia/regurgitation," and "micronutrient status." The main limitation of this study was that it was based in the United Kingdom only. CONCLUSIONS The COS is recommended to be used as a minimum in all trials of bariatric and metabolic surgery. Adoption of the COS will improve data synthesis and the value of research data. Future work will establish methods for the measurement of the outcomes in the COS.

Abstract
BACKGROUND It has been proven that bariatric surgery affects weight loss. Patients with morbid obesity have a significantly lower quality of life (QOL) and body image compared with the general population. OBJECTIVE To evaluate QOL, body image, and general self-efficacy (GSE) in patients with morbid obesity undergoing bariatric surgery within clinical parameters. SETTINGS Monocentric, prospective, longitudinal cohort study. METHODS Patients completed the short form 36 (SF-36) for QOL, body image questionnaire, and GSE scale 3 times: before surgery and within 6 months and 24 months after surgery. Influence of gender, age, and type of procedure, either laparoscopic sleeve gastrectomy (SG) or laparoscopic Roux-en-Y gastric bypass, were analyzed. RESULTS Thirty patients completed the questionnaires before and within 6 and 24 months after surgery. SF-36 physical summary score improved significantly from 34.3±11.0 before surgery to 46.0±10.4 within 6 months (P<.001) and to 49.8±8.2 within 24 months (P<.001) after surgery. SF-36 mental summary score improved significantly from 42.1±14.7 before surgery to 52.3±8.4 within 6 months (P<.001) and to 48.4±12.2 within 24 months (P<.001) after surgery. There were no significant differences between gender, age, and type of operation. Body image and GSE improved significantly after bariatric surgery (P<.001), and both correlated to the SF-36 mental summary score. CONCLUSION QOL, body image, and GSE improved significantly within 6 months and remained stable within 24 months after bariatric surgery. Improvements were independent of gender, age, and type of operation. Mental QOL was influenced by body image and GSE.

Abstract
AIMS Patient selection of weight management treatment option is often guided by a variety of factors. Currently, there is no comprehensive tool to facilitate informed decision-making for patients and clinicians. This article aims to synthesise evidence on the treatment effectiveness, health benefits, risks, and patient experiences of treatment options presently available at the Weight Management Clinic at The Ottawa Hospital (TOH), as a first step towards developing a decision aid. METHODS Narrative and systematic reviews published in English between 1999 and 2014 were included that focused on one or more of the following weight management treatments in adults aged 18 years and over: roux-en-y gastric bypass (RYGB), sleeve gastrectomy (SG), medically supervised meal replacement, and behavioural or lifestyle intervention. RESULTS Overall, bariatric surgeries have received the greatest research attention and have been associated not only with greater weight loss and health benefit but also with greater risks, complications, and financial cost. Dietary programmes demonstrated weight loss and health benefits to a lesser extent than with surgery but were associated with lower and shorter-term risks and complications. Behavioural and lifestyle interventions have been studied less yet have shown significant, albeit small, weight loss outcomes alone and in combination with dietary or surgical options; they also appear to be the lowest risk interventions. Patient experiences of weight management options are mixed and not well understood. CONCLUSION Further research is needed; however, this review identified some general trends related to weight loss outcomes, benefits, risks, and barriers for weight management options that have implications for shared treatment decision-making.

Abstract
OBJECTIVE Bariatric surgery results in significant weight loss in the majority of patients. Improvement in health-related quality of life (HRQoL) is an equally important outcome; however, there are few studies reporting long-term (≥5 years) HRQoL outcomes. This study assesses the quality of evidence and effectiveness of surgery on HRQoL ≥ 5 years. METHODS PubMed, Cochrane Review, EmBase, CINANL, PsycInfo, obesity conference abstracts, and reference lists were searched. Keywords were bariatric surgery, obesity, and quality of life. Studies were included if (1) there was ≥5 years follow-up, (2) patients had class II or III obesity, (3) individuals completed a validated HRQoL survey, and (4) there was a nonsurgical comparison group with obesity. Two reviewers independently assessed each study. RESULTS From 1376 articles, 9 studies were included in the systematic review (SR) and 6 in the meta-analysis (MA). Inconsistent results for long-term improvements in physical and mental health emerged from the SR. In contrast, the MA found significant improvements in these domains ≥5 years after surgery. CONCLUSIONS Study findings provide evidence for a substantial and significant improvement in physical and mental health favoring the surgical group compared with controls spanning 5 to 25 years after surgery.
