Primary Care Physicians' Perceptions of Bariatric Surgery and Major Barriers to Referral

Multidisciplinary Approach on Metabolic Bariatric Surgery Evasion: Analysis of Predictors and Potential Influencing Factors in the Preoperative Period

This study aims to identify evasion predictors and factors in the preoperative period of metabolic bariatric surgery (MBS) through a review and evaluations of professionals involved, as well as patient knowledge and information, aiming at positive long-term results. This article performed a systematic literature review (SLR) in the PubMed, Scopus, and Web of Science databases. It used the PRISMA Protocol with a record of 7 years to obtain documents published a year before the pandemic, during and after it. The search strategy resulted in 4649 records, of which 51 studies were included in the review. Subsequently, an analysis was carried out in which the professionals who met the patient participated in a qualitative survey, in which the results were analyzed and compared to those obtained in the SLR. The decision to undergo MBS is influenced by fears, uncertainties, and the need for support, particularly for elderly patients. Health professionals are crucial in providing continuous guidance and support throughout the process.

How Weight Bias and Stigma Undermine Healthcare Access and Utilization

PURPOSE OF REVIEW

To highlight recent evidence of the impact of weight bias and stigma on healthcare access and utilization.

RECENT FINDINGS

Healthcare access for patients with obesity is limited by weight-discriminatory policies such as body mass index cutoffs and weight loss requirements. These policies are based on flawed justifications without demonstrated medical benefits. Healthcare providers continue to hold negative views of patients with obesity, but recent evidence does not suggest that providers' weight-stigmatizing attitudes affect obesity treatment referrals. With the rise of new anti-obesity medications, more research is needed to understand how weight stigma may or may not affect providers' prescribing behavior and patients' access to this form of treatment. Experienced, anticipated, and internalized weight stigma is associated with patients' avoidance of healthcare and reduced utilization. Weight bias and stigma limit healthcare access and utilization. Structural changes are needed to remove weight-discriminatory barriers to care.

The Role of Informal Social Support for Patients Undergoing Bariatric Surgery

BACKGROUND

Bariatric surgery is underutilized as a treatment for metabolic disease and its associated comorbidities. While social support is known to play a crucial role in outcomes following bariatric surgery, little is known about the role of social support prior to surgery, which may impact preparedness for and willingness to undergo surgery. The study's objective was to examine the role of informal social support prior to bariatric surgery, the types of support received, and patient attitudes toward different demonstrations of support.

METHODS

We conducted semi-structured interviews with patients who had previously undergone bariatric surgery (n = 20) from two high-volume bariatric surgery centers. Interviews focused on patient engagement with and attitudes about social support during the preoperative process. Transcripts from each interview were iteratively analyzed through steps informed by deductive and inductive thematic analysis.

RESULTS

Four major themes emerged characterizing social support among patients undergoing bariatric surgery: (1) emotional support, (2) instrumental support, (3) informational support, and (4) self-support. Examples of meaningful support participants received included "cheerleading" (i.e., unconditional encouragement), advice from role models who had previously undergone surgery (e.g., receiving information on the process), shared experiences with loved ones regarding dietary and activity modifications (e.g., exercising with friends), and self-support measures (e.g., seeking therapy).

CONCLUSIONS

A comprehensive understanding of how patients receive informal social support can offer valuable insights for individuals considering surgery. Further, such knowledge may enable providers to effectively counsel patients through the decision-making process and to ensure the establishment of support systems both pre- and post-surgery.

Disparities in Access to Bariatric Surgery in North Carolina

BACKGROUND

This study sought to identify factors that contribute to disparities in access to bariatric surgery in North Carolina (NC).

METHODS

Using the rate of bariatric surgery in the county with the best health outcome as the reference, we calculated the Surgical Equity Index (SEI) in the remaining counties in NC.

RESULTS

Approximately 2.95 million individuals (29%) were obese in NC. There were 992 (.5%) bariatric procedures performed on a population of 194 209 individuals with obesity in the Reference County (RC). The mean SEI for bariatric surgery in NC was .47 (SD .17, range .15-.95). A statistically significant difference was observed in 89 counties. Univariable analyses identified the following variables to be significantly associated with the SEI: percent of population living in rural areas (% rural) (relative rate change in SEI [RR] = .994, 95% CI .92-.997; <.0001), median household income (RR = 1.0, 95% CI = 1.0-1.0; P = .0002), prevalence of diabetes (RR = .947, 95% CI .917-.977; .0006), the primary care physician ratio (RR = .995, 95% CI .991-.998; P = .006), and percent uninsured adults (RR = .955, 95% CI .927-.985; P = .003). By multivariable hierarchical regression analysis, only the % rural remained statistically associated with a low SEI (RR = .995 per 1% increase in % rural, 95% CI = .992, .998; P = .0002).

DISCUSSION

The percent rural is the most significant predictor of disparities in access to bariatric surgery. For every 1% increase in % rural, the rate of surgery decreased by .5%. Understanding the characteristics of rurality that are barriers to access is crucial to mitigate disparities in bariatric surgical access in NC.

Dissemination of the 2022 ASMBS and IFSO Guidelines for Bariatric Surgery: What Has Reached Primary Care Providers?

BACKGROUND

Only 1% of Americans eligible for metabolic and bariatric surgery (MBS) receive MBS. Prior studies have analyzed primary care provider (PCP) referral patterns and perceptions of MBS as a potential barrier to increasing MBS. However, less data exists regarding PCP knowledge of MBS indications and outcomes. Following the 2022 update to the indications for MBS by the ASMBS and IFSO, the number of eligible patients is only expected to increase. We evaluated PCP knowledge regarding the existence of the 2022 ASMBS and IFSO updated guidelines, MBS indications, and MBS outcomes.

METHODS

An 11-question survey was emailed to primary care residents, advanced practice providers, and faculty at a single institution.

RESULTS

Of 151 surveys distributed, 39.7% responded (n = 60). 95% were unaware of the 2022 updated guidelines. On multiple choice questions, 16.3% correctly identified the average weight loss from MBS, and 46.8% correctly answered the diabetes remission rate following MBS. Trainee answers were not statistically significant from practicing PCPs. Fifteen respondents had referred a patient for MBS, but this subgroup did not perform significantly better on the assessment. A total of 72.3% of respondents reported inadequate MBS education during their training, and 85.1% were interested in additional education.

CONCLUSIONS

We present the first assessment of PCP MBS knowledge since the release of the 2022 updated ASMBS and IFSO guidelines. This study indicates a gap in PCPs' knowledge regarding the updated guidelines and represents an opportunity for collaboration with our primary care colleagues to provide further MBS education.

Primary care physicians' knowledge and attitudes about obesity, adherence to treatment guidelines and its' association with confidence to treat obesity at the Saudi Ministry of Interior primary health care centers

Background and Aim

Many primary care physicians (PCPs) believed that managing overweight and obesity is essential to their jobs, however, many believe that they were doing it ineffectively, unsatisfying, and had negative attitudes. We conducted this study to explore the knowledge, attitudes and adherence to obesity management guidelines, identify potential barriers that may prevent adherence of PCPs to obesity treatment guidelines.

Methods

We conducted this cross-sectional study and conducted a questionnaire sent via email to all PCPs in the Ministry of Interior centers in Riyadh, Al-Kharj, AlQassim, Wadi Ad Dawasir, Hail and Tabuk in Saudi Arabia.

Results

A total of 119 PCPs participated in the survey, 61 (51.3%) males and 58 (48.7%) females. All respondents (n = 119, 100%) answered correctly that obesity is a disease. Of PCPs surveyed, genetics accounted for 75.6% of the responses as the cause of obesity. 79.8% believed that the best way for patients with obesity to lose weight was to engage in regular physical activity. The majority of PCPs (87.4%) thought that treating obesity should be a top priority, and 88.2% would typically recommend obesity therapy to their patients. Around 68.9% of PCPs thought that it's their patients' responsibility to lose weight. The majority will recommend obesity treatment and 75.6% would talk to their patients about weight concerns, while 60.5% would refer their patients to obesity surgery. There was a positive significant association between higher knowledge and better attitude and better adherence to treatment guidelines. More experienced PCPs were more confident. The most common perceived barrier was the patients' lack of desire to follow obesity treatment.

Conclusion

Primary care clinics and PCPs play a crucial role in diagnosing and treating patients with obesity, according to Ministry of Health guidelines on the prevention and management of obesity. PCPs must not only acknowledge obesity as a chronic illness and the possible long-term consequences it may cause, but also provide comprehensive, multi-component interventions that include lifestyle changes, medication, and appropriate referrals for bariatric surgery when needed. Healthcare professionals must form a cooperative relationship with obese patients to ensure that the patients follow treatment protocols.

The Patient's Journey in Obesity within the United States: An Exercise of Resilience against Disease

Obesity is often viewed as a result of patient failure to adhere to healthy dietary intake and physical activity; however, this belief undermines the complexity of obesity as a disease. Rates of obesity have doubled for adults and quadrupled for adolescents since the 1990s. Without effective interventions to help combat this disease, patients with obesity are at increased risk for developing type 2 diabetes, heart attack, stroke, liver disease, obstructive sleep apnea, and more. Patients often go through several barriers before they are offered pharmacotherapy or bariatric surgery, even though evidence supports the use of these interventions earlier. This partially stems from the cultural barriers associated with using these therapies, but it is also related to healthcare provider bias and limited knowledge of these therapies. Finally, even when patients are offered treatment for obesity, they often run into insurance barriers that keep them from treatment. There needs to be a cultural shift to accept obesity as a disease and improve access to effective treatments sooner to help decrease the risk of health complications associated with obesity.

Surveying the Knowledge and Practices of Primary Care Residents in Managing Adult Patients with Obesity

BACKGROUND

The prevalence of obesity is increasing worldwide at an alarming rate, yet obesity remains under-addressed during clinic encounters. A lack of training in how to treat obesity is one crucial factor contributing to this deficiency.

OBJECTIVE

This study explored resident physicians' perceptions of their education on obesity and its relationship with confidence and practice behaviors when caring for patients with obesity.

DESIGN

A survey was distributed to residency directors to share with residents in their programs. Participation was voluntary and anonymous. Data was collected over a 3-month period.

PARTICIPANTS

Residents in Family Medicine and Internal Medicine programs in West Virginia and Indiana who saw adult patients in an ambulatory care setting.

MAIN MEASURES

The electronic survey queried the presence of a formal curriculum on Obesity Medicine (OM) and each resident's knowledge, confidence, practice behaviors, and attitudes pertaining to OM.

KEY RESULTS

The survey was distributed to 490 residents in 12 programs. Response rate was 22.9% (112 resident physicians). All respondents felt that medical training in obesity should be strengthened. Residents who reported having a formal curriculum on OM were more likely than those without a curriculum to rate their confidence as "high" when discussing weight (35.0% vs. 16.7%, p = 0.03) and when counseling patients about diet and nutrition (37.5% vs. 18.1%, p = 0.02). They also more frequently reported learning enough from faculty to manage obesity (65.0% vs. 29.2%, p < 0.001). Residents with an OM curriculum reported discussing obesity as a problem with patients (100.0% vs. 86.1%, p = 0.01), and completing motivational interviews (90.0% vs. 58.3%, p =  < 0.001), more frequently than their peers without a curriculum.

CONCLUSIONS

Residents with a formal OM curriculum were more confident in addressing and discussing obesity with patients. Formal training in OM will strengthen resident training to better address and treat patients with obesity.

Barriers to metabolic surgery and how to address them

After bariatric surgery, patients with obesity achieve sustainable weight loss, gain in mobility, quality of life and life expectancy. Bariatric surgery can lead to remission of type 2 diabetes or to long term glycaemic control for patients with type 2 diabetes, while medical treatment has a preventive efficacy on micro and macrovascular complications. This has led to the concept of metabolic surgery to treat type 2 diabetes. Despite the benefits, only a small proportion of eligible patients undergo bariatric/metabolic surgery. Powerful antidiabetic medications, self-estimated lack of knowledge by medical professionals and fear of surgical complications are some of the arguments to prefer medical treatment of type 2 diabetes obesity versus metabolic surgery. We have reviewed in this paper the barriers which explain the low referral rate to metabolic surgery. With the point of view of the diabetologist, the general practitioner and the patient, we have addressed them to help clinicians and patients model an evidenced-based patient-oriented medical plan.

Changing Knowledge and Attitudes towards Bariatric Surgery in Primary Care: a 10-Year Cross-Sectional Survey

BACKGROUND

Some 28% of the Scottish population suffer from obesity. Bariatric procedures per population carried out in England when compared to Scotland (NBSR 2018) are significantly higher. Primary care practitioners (PCP) influence equality of access to secondary care bariatrics and frequently manage post-operative bariatric patients. Examining changes in PCP knowledge and attitude could improve access to bariatric procedures in Scotland.

METHODS

Following a sample pilot, all PCPs within three Scottish NHS health boards were emailed a questionnaire-based survey (2011; n = 902). A subsequent 10-year follow-up encompassed a greater scope of practice, additionally distributed to all PCPs in five further health boards (2021; n = 2049).

RESULTS

Some 452 responses were achieved (2011, 230; 2021, 222). PCPs felt bariatric surgery offered a greater impact in both weight management and that of obesity-related diseases (p < .0001). More PCPs were aware of local bariatric surgical referral criteria (2011, 43%; 2021, 57% (p = .003)), and more made referrals (2011, 60%; 2021, 72% (p = .018)) but were less familiar with national bariatric surgical guidelines (2011, 70%; 2021, 48% (p < .001)). Comfort at managing post-operative bariatric surgical patients were unchanged (2011, 24%; 2021, 27% (p = .660)). Minimal progress through dietetic-lead weight management services, plus rejection of patients thought to be good candidates, was reasons for referral hesitancy.

CONCLUSION

Over 10 years, PCPs were more aware of local referral criteria, making increased numbers of referrals. Knowledge deficits of national guidelines remain, and overwhelmingly PCPs do not feel comfortable looking after post-operative bariatric surgical patients. Further research into PCP educational needs, in addition to improving the primary to secondary care interface, is required.

Providers' Knowledge and Perceptions of Bariatric Surgery: a Systematic Review

Bariatric surgery remains underutilized despite its proven efficacy in the management of obesity. Provider perceptions of bariatric surgery are important to consider when discussing utilization rates. PubMed, SCOPUS, and OVID databases were searched in April 2023, and 40 published studies discussing providers' knowledge and perceptions of bariatric surgery were included. There were generally positive perceptions of the efficacy of bariatric surgery, although overestimations of surgical risks and postoperative complications were common. Providers' previous training was associated with knowledge and perceptions of bariatric surgery and familiarity with perioperative management across studies. These perceptions were also associated with referral rates, suggesting that inadequate provider knowledge may contribute to bariatric surgery underutilization. We advocate for increased bariatric surgery-related education throughout all stages of medical training and across specialties.

A qualitative analysis of Black men's attitudes toward obesity and bariatric surgery

BACKGROUND

Metabolic and bariatric surgery (MBS) is a safe and highly effective treatment for morbid obesity and related co-morbidities. While MBS access and insurance coverage have greatly improved, sex and racial disparities remain in utilization of MBS.

OBJECTIVE

To identify novel intrinsic factors that may explain Black underutilization of surgical treatments for weight management.

SETTING

This study was conducted in metropolitan communities of Western New York.

METHODS

We conducted semistructured face-to-face interviews with 27 adult Black men with a history of obesity and at least 2 obesity-related conditions (diabetes, hypertension, and/or chronic kidney disease [CKD]), about their attitudes, beliefs, behaviors, and habits related to obesity and obesity management. Interview transcripts were reviewed using thematic analysis for patterns and themes.

RESULTS

Most participants did not perceive obesity as a serious health condition and those who had weight-loss goals did not aim for a healthy body mass index (BMI). Trust and respectful communication with physician were very important in making healthcare decisions. MBS was perceived as extreme and dangerous option for weight loss, and only participants with severe symptoms such as chronic pain were open to discussing MBS with their providers. Participants acknowledged lack of role models of similar background who had successfully undergone MBS for obesity.

CONCLUSIONS

This study identified misinformation about risks and benefits of MBS and lack of community role models as important factors contributing to Black men's unwillingness to consider MBS. Further research is needed to facilitate patient-provider communication about weight and improve provider's ability and motivation for weight management in primary care settings.

Attitudes of primary care physicians toward bariatric surgery: a free word association networks analysis

BACKGROUND

Primary care physicians (PCPs) hold major responsibility in referring patients with obesity eligible for bariatric surgery (BS).

OBJECTIVE

The aim was to explore PCPs' mental representation of BS in order to identify barriers and catalysts of BS referral practices.

SETTING

Switzerland.

METHODS

A total of 3526 PCPs were invited to participate in an online survey. PCPs were asked to write the first 5 words that came to their mind about the term "bariatric surgery." Additionally, they had to pick 2 emotions that best described each provided association. Demographic data and obesity-related referral patterns were collected. Mental representation network was constructed based on co-occurrence of associations, using validated data-driven methodology.

RESULTS

In all, 216 PCPs completed the study (response rate: 6.13%). Respondents were aged 55 ± 9.8 years, had an equal sex distribution, and practiced mainly in urban settings. Three mental representations of BS emerged: indication-focused (most frequent associations: "obesity," "diabetes"), treatment-focused ("gastric bypass," "weight loss"), and outcome-focused ("complications," "challenging follow-up"). The emotional label "interested" was used significantly more frequently in the treatment-focused group. Comparison of PCPs among mental modules showed that those with a treatment-focused mindset referred patients for BS most frequently and were significantly more willing to follow up with postbariatric patients (χ2 = 17.8, P = .022).

CONCLUSIONS

PCPs think about BS along 3 mental representations, and the treatment-focused attitude was coupled with the highest willingness to refer eligible patients for BS. Confidence in performing postbariatric follow-up was identified as catalyst of BS referral. Access to optimal care for patients with obesity may be improved accordingly.

Weight management treatment modalities in patients with overweight or obesity: A retrospective cohort study of administrative claims data

Background

The purpose of this study was to describe demographic and clinical characteristics among patients who have medical encounters for weight management treatments and to investigate the association of those characteristics with treatment modality.

Methods

This was a retrospective database study using medical claims, pharmacy claims, and enrollment information from commercial and Medicare Advantage with Part D members in the Optum Research Database from 01/01/2011-2/29/2020. Adult patients with a claim for a weight management treatment from 01/01/2012-2/28/2019 were categorized into cohorts according to the highest intensity intervention received. To examine the association between patient characteristics and treatment modality received, a multinomial logit model was performed.

Results

Cohorts by increasing intensity included lifestyle intervention (LSI, n = 67,679), weight reduction pharmacotherapy (WRRx) with an anti-obesity medication (AOM, n = 6,905), weight reduction procedure (WRP, n = 1,172), and weight reduction surgery (WRS, n = 18,036). Approximately 32.1% and 16.6% of patients who received WRS or WRP had an LSI during the 12-month baseline, and only 0.6% and 0.4% had treatment with long-term AOMs. In a multinomial logit model, patients with type 2 diabetes (not including WRRx cohort), respiratory disorders, cardiovascular risk factors, pain disorders, and mental health conditions had increased odds of treatment with higher intensity intervention versus LSI. Patients who were male, received an intervention more recently (2016-2019), or had a Charlson comorbidity score of 1 (compared to 0) had decreased odds of treatment with higher intensity interventions.

Conclusion

In this study, age, sex, body mass index, obesity-related complications, and Charlson comorbidity score appeared to influence the type of weight management treatment modality received. This study improves understanding of weight management treatment utilization and identifies gaps and opportunities to improve obesity care with the appropriate use of different treatment modalities.

A study analyzing outcomes after bariatric surgery by primary language

BACKGROUND

Communication is key to success in bariatric surgery. This study aims to understand how outcomes after bariatric surgery differ between patients with a non-English primary language and those with English as their primary language.

METHODS

This retrospective, observational cohort study of bariatric surgery patients age ≥ 18 years utilized the Michigan, Maryland, and New Jersey State Inpatient Databases and State Ambulatory Surgery and Services Databases, 2016 to 2018. Patients were classified by primary spoken language: English and non-English. Primary outcome was complications. Secondary outcomes included length of stay (LOS) and cost, with cost calculated using cost-to-charge ratios provided by Healthcare Cost and Utilization Project and reported in 2019 United States dollars. Multivariable regression models (logistic, Poisson, and quantile) were used to examine associations between primary language and outcomes. Given the uneven distribution of race by primary language, interaction terms were used to examine conditional effects of race.

RESULTS

Among 69,749 bariatric surgery patients, 2811 (4.2%) spoke a non-English primary language. Covariates, notably race distribution, and unadjusted outcomes differed significantly by primary language. However, after adjustment, non-English primary language was not associated with significantly increased odds of complications (odds ratio 1.24, p = 0.389), significantly different LOS (- 0.02 days, p = 0.677), nor significantly different mean healthcare costs (- $265, p = 0.309). There were no significant conditional effects of race seen among outcomes.

CONCLUSIONS

Though non-English primary language was associated with a significantly different distribution of observable characteristics (including race, income quartile, and insurance type), after adjustment, non-English primary language was not associated with significant differential risk of adverse outcomes after bariatric surgery, and there were no significant conditional effects of race. As such, this study suggests that disparities in bariatric surgery by primary spoken language more likely related to access to care, or the pre- and post-hospital care continuum, rather than index hospitalization after surgery.

Doctors' Perception Regarding Bariatric Surgery and Major Barriers in Referral of Morbidly Obese Patients for Surgery in Khyber Pakhtunkhwa

INTRODUCTION

Obesity is on the rise worldwide and has emerged as a global health concern. It has presented itself as the leading cause of morbidity, disability, and healthcare utilization. Bariatric surgery is a viable treatment option that offers sustained weight loss and improvement in comorbidities. The aim of this study is to determine the perception of doctors regarding bariatric surgery and the major barriers to the referral of morbidly obese for surgery.

METHOD

This study is a cross-sectional descriptive study conducted from November 1, 2022, to December 31, 2022. It involved prospective data collection through online questionnaires filled by doctors practicing in Peshawar. The sampling technique was non-probability convenience-based sampling. The sample size was 152. Doctors from all age groups and both genders were included in our study. Non-consenting doctors and those who were practicing bariatric surgery were excluded. Data were analyzed using a statistical package for social sciences (SPSS) version 25.0 (IBM Inc., Armonk, NY). Categorical variables have been presented as frequencies and percentages. Numerical variables have been presented as mean ± SD.

RESULTS

A total of 152 doctors participated in our research study; 92 were physicians and 60 were surgeons. The majority of our study participants' patient load per week was >75. Around 47% believed bariatric surgery was a valuable tool in the treatment of morbid obesity. The most commonly reported barrier to referral was surgical complications or side effects (28.9%).

CONCLUSION

The study concluded that the awareness regarding bariatric and metabolic surgery remains flimsy among the doctor community. Most of the physicians were unaware of the benefits of the surgical management of obesity. They also had doubts regarding the safety of the procedure. We need proper utilization of awareness strategies to overcome these barriers.

Primary care providers' perceived barriers to obesity treatment and opportunities for improvement: A mixed methods study

BACKGROUND

Primary care patients with obesity seldom receive effective weight management treatment in primary care settings. This study aims to understand PCPs' perspectives on obesity treatment barriers and opportunities to overcome them.

STUDY DESIGN

This is an explanatory sequential mixed methods study in which survey data was collected and used to inform subsequent qualitative interviews.

SETTINGS AND PARTICIPANTS

PCPs who provide care to adult patients in an academic medical center in the Midwestern US.

METHODOLOGY

PCPs (n = 350) were invited by email to participate in an online survey. PCPs were subsequently invited to participate in semi-structured interviews to further explore survey domains.

ANALYTIC APPROACH

Survey data were analyzed using descriptive statistics. Interviews were analyzed using directed content analysis.

RESULTS

Among 107 survey respondents, less than 10% (n = 8) used evidence-based guidelines to inform obesity treatment decisions. PCPs' identified opportunities to improve obesity treatment including (1) education on local obesity treatment resources (n = 78, 73%), evidence-based dietary counseling strategies (n = 67, 63%), and effective self-help resources (n = 75, 70%) and (2) enhanced team-based care with support from clinic staff (n = 53, 46%), peers trained in obesity medicine (n = 47, 44%), and dietitians (n = 58, 54%). PCPs also desired increased reimbursement for obesity treatment. While 40% (n = 39) of survey respondents expressed interest in obesity medicine training and certification through the American Board of Obesity Medicine, qualitative interviewees felt that pursuing training would require dedicated time (i.e., reduced clinical effort) and financial support.

CONCLUSIONS

Opportunities to improve obesity treatment in primary care settings include educational initiatives, use of team-based care models, and policy changes to incentivize obesity treatment. Primary care clinics or health systems should be encouraged to identify PCPs with specific interests in obesity medicine and support their training and certification through ABOM by reimbursing training costs and reducing clinical effort to allow for study and board examination.

Apprehensions of Morbidly Obese People Regarding Bariatric Surgery

Introduction Obesity has emerged as a major public health issue in both developed and developing countries. The prevalence of obesity is on the rise. Bariatric surgery is acknowledged as the most effective and safe solution for this problem. It has been shown to be effective in sustained weight loss and improving quality of life. The aim of this study was to identify the causes of reluctance to have surgery among patients who were potential candidates for weight loss procedures. Method Morbidly obese people who were enrolled at Khyber Teaching Hospital, Peshawar, from December 2021 to August 2022 were included in the study. It included hospitalized as well as outpatient appointments. A questionnaire was adopted as the data collection tool. Result A total of 107 patients (58 men and 49 women) were enrolled in the study. The median age was 42. Of the 107 patients, 5% (n=5) of the patients were super morbidly obese (BMI >50kg/m2). Seventy-two percent (n=77) of the population considered themselves morbidly obese. Only 22% (n=24) were physically active. Twenty percent (n=21) of the patients reported that they have or are currently trying dietary modifications for weight loss. Young females were most likely to be on dieting programs. Importantly, 56% (n=60) had never heard of bariatric surgery. Exploring the reasons for reluctance among patients revealed that the concern for surgical mortality was the major hindrance. This was followed by being not interested in committing to surgery and recovery. Concerns regarding cost and financing were also the reasons candidates didn't opt for surgical procedures to treat obesity. Conclusion The study concluded that there is a serious lack of knowledge and awareness among physicians and the general public regarding bariatric surgery. Most of the patients who were potential candidates for the procedure weren't aware that obesity had a surgical and definitive treatment. Patients who were aware of the surgical procedure were hesitant to undergo surgery for the management of their weight as they harbored misconceptions, particularly regarding the safety and efficacy of the procedure.

Identifying barriers to shared decision-making about bariatric surgery in two large health systems

OBJECTIVE

Prior research suggests shared decision-making (SDM) could improve patient and health care provider communication about bariatric surgery. The aim of this work was to identify and prioritize barriers to SDM around bariatric surgery to help guide implementation of SDM.

METHODS

Two large US health care systems formed multidisciplinary teams to facilitate the implementation of SDM around bariatric surgery. The teams used a nominal group process approach involving (1) generation of multilevel barriers, (2) round-robin recording of barriers, (3) facilitated discussion, and (4) selection and ranking of barriers according to importance and feasibility to address.

RESULTS

One health system identified 13 barriers and prioritized 5 as the most important and feasible to address. The second health system identified 14 barriers and prioritized 6. Both health systems commonly prioritized six barriers: lack of insurance coverage; lack of understanding of insurance coverage; lack of organizational prioritization of SDM; lack of knowledge about bariatric surgery; lack of interdepartmental clarity between primary and specialty care; and limited training on SDM conversations and tools.

CONCLUSIONS

Health systems face numerous barriers to SDM around bariatric surgery, and these can be easily identified and prioritized by multistakeholder teams. Future research should seek to identify effective strategies to address these common barriers.

Cost-effectiveness of Staple Line Reinforcement in Laparoscopic Sleeve Gastrectomy

OBJECTIVE

To perform a cost-effectiveness analysis of staple-line reinforcement in laparoscopic sleeve gastrectomy.

SUMMARY OF BACKGROUND DATA

Exponential increases in surgical costs have underscored the critical need for evidence-based methods to determine the relative value of surgical devices. One such device is staple-line reinforcement, thought to decrease bleeding rates in laparoscopic sleeve gastrectomy.

METHODS

Two intervention arms were modeled, staple-line reinforcement and standard nonreinforced stapling. Bleed and leak rates and 30-day treatment costs were obtained from national and state registries. Quality-adjusted life-year (QALY) values were drawn from previous literature. Device prices were drawn from institutional data. A final incremental cost-effectiveness ratio was calculated, and one-way and probabilistic sensitivity analyses were performed.

RESULTS

A total of 346,530 patient records from 2012 to 2018 were included. Complication rates for the reinforced and standard cohorts were 0.05% for major bleed in both cohorts ( P = 0.8841); 0.45% compared with 0.59% for minor bleed ( P < 0.0001); and 0.24% compared with 0.26% for leak ( P = 0.4812). Median cost for a major bleed was $5552 ($3287, $16,817) and $2406 ($1861, $3484) for a minor bleed. Median leak cost was $9897 ($4589, $21,619) and median cost for patients who did not experience a bleed, leak, or other serious complication was $1908 ($1712, $2739). Mean incremental cost of reinforced stapling compared with standard was $819.60/surgery. Net QALY gain with reinforced stapling compared with standard was 0.00002. The resultant incremental cost-effectiveness ratio was $40,553,000/QALY. One-way and probabilistic sensitivity analyses failed to produce a value below $150,000/QALY.

CONCLUSIONS

Compared with standard stapling, reinforced stapling reduces minor postoperative bleeding but not major bleeding or leaks and is not cost-effective if routinely used in laparoscopic sleeve gastrectomy.

Primary Care Physicians' Knowledge, Attitude, and Potential Referral Barriers towards Bariatric Surgery: A Northern Saudi Study

Introduction: Bariatric surgery is the most effective procedure for sustained weight loss and control of obesity-associated comorbidities among morbidly obese patients. Successful bariatric surgery depends on a multidisciplinary approach involving all healthcare workers, including the primary care physicians, from the referral of patients to long-term follow-up. The present study assessed the knowledge, attitude, and potential referral barriers of primary care physicians to bariatric surgery and associated sociodemographic factors. Materials and methods: The present analytical cross-sectional study was conducted among 280 randomly selected primary care physicians using a standard and validated data collection tool. We performed an independent t-test and one-way ANOVA to find the association between sociodemographic characteristics and knowledge, attitude, and referral barrier scores. Furthermore, multilinear regression analysis was executed to determine the association among knowledge, attitude, and barriers. Results: The current study found that 52.9%, 19.3%, and 59.3% had a low score in the knowledge, attitude, and barriers categories. The attitude scores were significantly associated with the education status (p = 0.005) and current position at primary health centers (p = 0.012), and the referral barriers score was significantly associated with the work experience duration (p = 0.004). We found a positive relationship between knowledge and attitude (regression coefficient (β) [95% CI]:0.389 [0.154 to 0.585], p = 0.001) and a negative relationship between knowledge and referral barriers (β [95% CI]: -0.291 [-0.127 to -0.058], p = 0.007). Conclusions: Our survey findings suggest that a lack of knowledge regarding bariatric surgery led to several concerns and referral barriers among the physicians. Therefore, the recommendation is to improve the primary care physicians' knowledge through continuing medical education, symposium, and other suitable training methods with a special focus on obesity care in the curriculum. Furthermore, a mixed-method survey involving other provinces of the KSA is warranted to formulate the region-specific training needs.

Questioning the legitimacy of bariatric surgery: a qualitative analysis of individuals from the community who qualify for bariatric surgery

BACKGROUND

Little is known about how individuals in the community who qualify for bariatric surgery perceive it and how this affects their likelihood to consider it for themselves. This study is the first qualitative study of a racially and ethnically diverse cohort to understand perceptions of bariatric surgery.

METHODS

We designed a descriptive study to understand attitudes about bariatric surgery. We interviewed 32 individuals who met NIH criteria for bariatric surgery but have never considered bariatric surgery. We purposively sampled to ensure the majority of participants were non-white. Using an Interpretive Description framework, an exploratory, iterative method was used to code interviews and arrive at final themes.

RESULTS

Participants self-identified as 88% female, 75% Black, 3% Hispanic, 3% Pacific Islander, and 19% white. Three major themes emerged from our data regarding legitimacy of bariatric surgery. First, participants perceived bariatric surgery to be something commercialized rather than needed treatment. They equated bariatric surgery with "botulism of the lips" or "cool sculpting." Second, an important contributor to the lack of legitimacy as a medical treatment was that many had not heard about bariatric surgery before from their doctors. Doctors were trusted sources for legitimate information about health. Lastly, conflicting information over bariatric surgery-related diet and weight loss further diminished the legitimacy of bariatric surgery. As one participant reflected about pre-operative weight loss requirements, "[If] I'm going to do that, I might as well just keep losing the weight. Why even go do the surgery?".

CONCLUSION

Though bariatric surgery is a safe, effective, and durable therapy for patients with obesity, the majority of individuals we interviewed had concerns over the legitimacy of bariatric surgery as a medical treatment. Moving forward in reaching out to communities about bariatric surgery, healthcare providers and systems should consider the presentation of information to attenuate these concerns.

Ten Years of Change in Bariatric/Metabolic Surgery in the Asia-Pacific Region with COVID-19 Pandemic: IFSO-APC National Reports 2021

BACKGROUND

On November 25, 2021, the IFSO-Asia-Pacific Chapter (IFSO-APC) Virtual Meeting 2021 was held online, and the representatives from the Asia-Pacific region presented 10 years of change in bariatric/metabolic surgery and the influence of COVID-19 in the special session of "IFSO-APC National Reports 2010-2020". We herein report the summarized data.

METHODS

National bariatric/metabolic surgery data, which included the data of 2010 and 2020, were collected from the representatives using a questionnaire that consisted of 10 general questions. At the congress, the data were calculated and summarized.

RESULTS

Thirteen of the 14 national societies responded to the survey. From 2010 to recent years, the populations of individuals with obesity (BMI ≥ 30 kg/m2) and individuals with diabetes both significantly increased. Eight countries and regions expanded the lower limit of criteria for bariatric surgery by 2-5 kg/m2 (BMI), and 5 countries newly established criteria for metabolic surgery in the last ten years. Sixty-nine percent of the countries currently run public health insurance systems, which doubled from 2010. The number of bariatric surgeons and institutions increased more than threefold from 2010. In 2010, 2019, and 2020, surgeons in IFSO-APC societies performed 18,280, 66,010, and 49,553 bariatric/metabolic surgeries, respectively. Due to the COVID pandemic, restriction policies significantly reduced access to surgery in South and Southeast Asian countries. The biggest changes included increased numbers of bariatric surgeons and institutions, operation numbers, public insurance coverage, raising awareness, and national registry systems.

CONCLUSION

For the last 10 years, bariatric/metabolic surgery has rapidly grown in the Asia-Pacific region.

Comparative effectiveness of sleeve gastrectomy vs Roux-en-Y gastric bypass in patients giving birth after bariatric surgery: reinterventions and obstetric outcomes

BACKGROUND

Women of childbearing age comprise approximately 65% of all patients who undergo bariatric surgery in the USA. Despite this, data on maternal reintervention and obstetric outcomes after surgery are limited especially with regard to comparative effectiveness between sleeve gastrectomy and Roux-en-Y gastric bypass, the most common procedures today.

METHODS

Using IBM MarketScan claims data, we performed a retrospective cohort study of women ages 18-52 who gave birth after undergoing laparoscopic sleeve gastrectomy or Roux-en-Y gastric bypass with 2-year continuous follow-up. We balanced the cohort on observable characteristics using inverse probability weighting. We utilized multivariable logistic regression to examine the association between procedure selection and outcomes, including risk of reinterventions (revisions, enteral access, vascular access, reoperations, other) or adverse obstetric outcomes (pregnancy complications, severe maternal morbidity, and delivery complications). In all analyses, we controlled for age, U.S. state, and Elixhauser or Bateman comorbidities.

RESULTS

From 2011 to 2016, 1,079 women gave birth within the first two years after undergoing bariatric surgery. Among these women, we found no significant difference in reintervention rates among those who had gastric bypass compared to sleeve gastrectomy (OR 1.41, 95% CI 0.91-2.21, P = 0.13). We then examined obstetric outcomes in the patients who gave birth after bariatric surgery. Compared to patients who underwent sleeve gastrectomy, those who had Roux-en-Y gastric bypass were not significantly more likely to experience any adverse obstetric outcomes.

CONCLUSION

In this first national cohort of females giving birth following bariatric surgery, no significant difference was observed in persons who underwent Roux-en-Y gastric bypass versus sleeve gastrectomy with respect to either reinterventions or obstetric outcomes. This suggests possible equipoise between these two procedures with regards to safety within the first two years following a bariatric procedure among women who may become pregnant, but more research is needed to confirm these findings in larger samples.

Perception of Bariatric Surgery and Endoscopic Bariatric Therapies Among Primary Care Physicians

INTRODUCTION

In the USA, less than 1% of eligible patients who qualify for bariatric surgery ultimately undergo surgery. Perceptions of endoscopic bariatric therapies (EBTs) for weight management remain unknown.

METHODS

A 22-question survey was distributed to primary care physicians (PCPs) across the Mayo Clinic healthcare system. Survey invitations were sent via email, and all surveys were unanimously conducted electronically.

RESULTS

A total of 130 PCPs participated in the survey (40% response rate). Twenty-four PCPs were between 20 and 24 years out of training (18.5%), and 71 (54.6%) were female. Most providers had a body mass index (BMI) between 18.5 and 24.9 kg/m² (n = 62, 47.7%). Among the weight loss options discussed during clinic visits, PCPs discussed lifestyle modification including diet and exercise (n = 129; 99.2%), and 68 PCPs (52.3%) were not aware of EBTs as weight loss interventions. While 46.2% of the PCPs agreed that a bariatric endoscopy is an effective option for weight loss, only 24.6% of PCPs were familiar with the indications for EBTs. Most of the cohort (n = 69, 53.1%) experienced barriers in referring their patients. Moreover, most of the patients referred to bariatric clinics were from PCPs who had a BMI between 18.5 and 24.9 kg/m² (n = 62, 47.7%) as compared to PCPs with a BMI of 40 kg/m² and greater (n = 5, 3.8%).

CONCLUSIONS

Due to the rise of bariatric therapies in recent years, PCPs are increasingly involved in the referral and management of patients with obesity and obesity-related comorbidities. However, knowledge gaps regarding weight loss options, including EBTs, could limit optimal care to patients desiring medically monitored weight loss.

Stigma Toward Bariatric Surgery in the Netherlands, France, and the United Kingdom: Protocol for a Cross-cultural Mixed Methods Study

Background

Bariatric surgery is an effective procedure for the treatment of obesity. Despite this, only 0.1% to 2% of eligible individuals undergo surgery worldwide. The stigma surrounding surgery might be a reason for this. Thus far, no research has systematically studied the nature and implications of bariatric surgery stigma. The limited studies on bariatric surgery stigma are often conducted from the perspective of the public or health care professions and either use small and nonrepresentative samples or fail to capture the full essence and implications of the stigma altogether, including attitudes toward patients and perpetrators of the stigma. In addition, studies from patients’ perspectives are limited and tend to address bariatric surgery stigma superficially or implicitly. Finally, the extent to which cultural factors shape and facilitate this stigma and the experiences of patients have not yet been researched.

Objective

This study aimed to explore the perceptions, experiences, and consequences of bariatric surgery stigma from the perspective of the public, health care professionals, and patients before and after bariatric surgery. Furthermore, although the concept of stigma is universal, every society has specific cultural norms and values that define acceptable attributes and behaviors for its members. Therefore, this study also aimed to explore the extent to which cultural factors influence bariatric surgery stigma by comparing the Netherlands, France, and the United Kingdom.

Methods

This paper describes the protocol for a multiphase mixed methods research design. In the first part, we will conduct a scoping review to determine the current knowledge on bariatric surgery stigma and identify knowledge gaps. In the second part, semistructured interviews among patients before and after bariatric surgery will be conducted to explore their experiences and consequences of bariatric surgery stigma. In the third part, surveys will be conducted among both the public and health care professionals to determine the prevalence, nature, and impact of bariatric surgery stigma. Surveys and interviews will be conducted in the Netherlands, France, and the United Kingdom. Finally, data integration will be conducted at the interpretation and reporting levels.

Results

The study began in September 2020 and will continue through September 2025. With the results of the review, we will create an overview of the current knowledge regarding bariatric surgery stigma from patients’ perspectives. Qualitative data will provide insights into patients’ experiences with bariatric surgery stigma. Quantitative data will provide information related to the prevalence and nature of bariatric surgery stigma from the perspective of the public and health care professionals. Both qualitative and quantitative data will be compared for each country.

Conclusions

The findings from this study will lead to new insights that can be used to develop strategies to reduce bariatric surgery stigma and improve access, use, and outcomes of bariatric surgery.

Current Knowledge and Perceptions of Bariatric Surgery among Diabetologists and Internists in Poland

Perioperative care and follow-up after bariatric surgery (BS) engage various medical professionals. It is key for them to be well informed about these procedures. However, knowledge and attitudes may be not satisfactory enough to provide proper care. We aimed to assess knowledge and perceptions of BS among diabetologists and internists. A total of 34 diabetologists and 30 internists completed the electronic questionnaire. There were no differences in self-estimated knowledge between them, except regarding items related to the treatment of diabetes and metabolic control. Several misconceptions were identified in the questions testing the understanding of key issues in BS. Most participants considered BS effective in weight loss and metabolic control. A total of 75% highlighted the lack of appropriate equipment for dealing with morbidly obese patients. Interestingly, in a multivariable linear regression model, self-estimated knowledge was the only variable associated with frequency of referrals to bariatric surgeons. A total of 92% of respondents were interested in broadening their knowledge. Guidelines for long-term follow-up and funding were the most frequently chosen topics to explore. The study showed a positive attitude of diabetologists and internists towards surgical treatment of obesity and identified some significant gaps in knowledge. The results may be helpful in planning trainings to provide the best care for patients suffering from morbid obesity.

Turkish primary care physicians’ attitudes and knowledge of obesity and bariatric surgery: a survey study

Objective: This survey study attempted to determine Turkish primary care physicians’ (PCP) knowledge, attitudes, and perceptions of obesity treatment and bariatric surgery. Moreover, the relationship between the duration of practice as a physician, and especially the indications for bariatric surgery and referral to surgery were investigated.

Material and Methods: A survey of 27 questions was administered via social media and the internet using the SurveyMonkey platform. The physicians who responded to the survey were grouped based on the duration of working life. Among these groups, the responses to the questions about bariatric surgery were compared using univariate analysis.

Results: A total of 1044 physicians responded to the survey. The number of physicians who strongly agreed that a PCP should play role in the treatment of obesity was 743 (71.1%). The most important reason for not undertaking this treatment was reported as the requirement for a multidisciplinary approach to obesity treatment (51.5%, n= 537). The percentage of those who thought that patients with a body mass index (BMI) above 40 kg/m2 should be referred to surgery was 72.3%,while the percentage of those referring patients with a BMI of 35-40 kg/m2 and comorbidities to surgery was 53.3%, and the percentage of those referring patients with a BMI of 35-40 kg/m2 and uncontrolled diabetes to surgery was 35.9%. Physicians who were new to the profession were found to evaluate surgical indications more positively (p< 0.05).

Conclusion: This study found that PCPs in Turkey had a basic knowledge of obesity treatment and were willing to treat and follow up these patients. However, it was observed that they could not adequately focus on this issue due to the requirement for a multidisciplinary approach to the disease and the workload. It was found that the young physiciansð level of knowledge of bariatric surgery was higher, but their attitudes towards patient referral were similar.

Patient-provider discussions of bariatric surgery and subsequent weight changes and receipt of bariatric surgery

OBJECTIVE

The purpose of this study was to determine whether patients who discuss bariatric surgery with their providers are more likely to undergo the procedure and to lose weight.

METHODS

A retrospective cohort study of adults with BMI ≥ 35 kg/m² treated between 2000 and 2015 was conducted to analyze the relationship between a discussion of bariatric surgery in the first year after study entry and weight changes (primary outcome) and receipt of bariatric surgery (secondary outcome) over 2 years after study entry. Natural language processing was used to identify the documentation of bariatric surgery discussion in electronic provider notes.

RESULTS

Out of 30,560 study patients, a total of 2,659 (8.7%) discussed bariatric surgery with their providers. The BMI of patients who discussed bariatric surgery decreased by 2.18 versus 0.21 for patients who did not (p < 0.001). In a multivariable analysis, patients who discussed bariatric surgery with their providers lost more weight (by 1.43 [change in BMI]; 95% CI: 1.29-1.57) and had greater odds (10.2; 95% CI: 9.0-11.6; p < 0.001) of undergoing bariatric surgery.

CONCLUSIONS

Clinicians rarely discussed bariatric surgery with their patients. Patients who did have this discussion were more likely to lose weight and to undergo bariatric surgery.

Primary care physicians' knowledge, attitudes and concerns about bariatric surgery and the association with referral patterns: a Swedish survey study

BACKGROUND

Obesity prevalence is increasing globally. Bariatric surgery is an effective treatment for severe and complex obesity resulting in significant and sustained weight loss. In Sweden, most bariatric surgery patients are referred by primary care physicians. We aimed to explore barriers for physicians to refer patients with severe and complex obesity for bariatric surgery.

METHODS

A questionnaire survey was in 2019 emailed to 1100 primary care physicians in the Skåne and Kronoberg regions in south Sweden. The survey focused on referral patterns, knowledge and attitudes towards bariatric surgery and concerns about postoperative complications. We created different statistical indices for referral patterns, knowledge, attitudes and concerns about bariatric surgery. To analyze the correlation between these indices, we did Spearman's correlations and regression analyses.

RESULTS

Of 1100 email respondents, we received 157 (14%) completed surveys. Among 157 physician respondents, 73% answered that they had good knowledge about the referral criteria for bariatric surgery, whereas 55 and 60% answered correctly to two items on criteria for bariatric surgery. A majority of respondents (84%) stated that their patients initiated referral to bariatric surgery. Half of the respondents had concerns about postoperative medical and surgical complications, but another half had a positive attitude to bariatric surgery as a treatment for obesity comorbidities. Almost half of the respondents (44%) answered that they needed to learn more about bariatric surgery. We found significant positive correlations between high knowledge and referral patterns (r = 0.292, p < 0.001) and positive attitudes (r = 0.235, p < 0.001) respectively. We found significant reverse correlations between concerns and referral patterns (r = - 0.355, p < 0.001) and between positive attitudes and concerns (r = - 0.294, p < 0.001). In logistic regression high levels of concerns explained low willingness to refer for bariatric surgery (Odds Ratio 0.2, 95% confidence interval 0.1-0.7).

CONCLUSION

According to this Swedish survey among primary care physicians, high levels of concerns about bariatric surgery among physicians seemed to be a barrier to refer patients with severe and complex obesity for bariatric surgery. Since high knowledge about obesity and bariatric surgery correlated negatively to concerns and positively to favorable attitudes to bariatric surgery, more knowledge about obesity and bariatric surgery is warranted.

Cost effectiveness of bariatric surgery in patients with obesity related comorbidities: A retrospective study

Background and Aim:

Bariatric surgery has been reported to be an effective but expensive method for obesity management. This study aimed to determine the economic benefit for patients who underwent bariatric surgery.

Methodology:

We conducted a retrospective chart review of patients who underwent bariatric surgery and was on medications for obesity-related comorbidities at the Obesity Research Center in King Khalid University Hospital, Riyadh, Saudi Arabia. Data on the use and cost of medications before and after bariatric surgery were collected.

Results:

A total of 266 patients, 107 males (40.23%), and 159 Females (59.77%) with a mean age of 41.06 years were included in the study. There was a reduction in the mean number of medications used by patients before and 1-year post-op (before: 1.84, after: 0.52), with a significant reduction in the cost of medications (SAR5152.24 before, and SAR1695.36 after, 67% reduction, P < 0.001). Patients < 32 years old had the most reduction in medications cost (76.64% reduction). No significant difference in the cost reduction after surgery between genders (P = 0.971). There were significant reductions in numbers of out-patient clinic visits (2.26 ± 2.43 to 1.57 ± 1.42) and in-patient hospitalizations (0.31 ± 0.57 to 0.10 ± 0.36) after surgery (P < 0.001 and P < 0.001, respectively).

Conclusion:

Bariatric surgery can be considered as a cost-effective treatment for patients with obesity-related comorbidities. A significant reduction has been found in post-operative medications cost, out-patient clinic visits and in-patient hospitalizations after bariatric surgery.
