Perception and Awareness of Bariatric Surgery in Canada: a National Survey of General Surgeons

A Dutch Survey on Medication Adjustments after Metabolic and Bariatric Surgery: Experiences of Bariatric Surgeons, Internists, Pharmacists, and General Practitioners

BACKGROUND

As metabolic and bariatric surgery (MBS) can alter the pharmacokinetics of drugs, post-bariatric surgery patients may require medication adjustments and monitoring. To improve pharmacotherapy in these patients, we aimed to understand the beliefs, attitudes, knowledge, and concerns of healthcare professionals who treat these patients.

METHODS

A survey by means of an online questionnaire was divided into six sections. It was sent to bariatric surgeons, internists, pharmacists, and general practitioners in the Netherlands.

RESULTS

Out of 229 returned surveys, 222 were included. Virtually all respondents (98%) expected MBS to influence the effect of medication. Both reduced efficacy (23%) and more adverse events or medication-related complications (21%) were recognized. Two-thirds of the respondents felt competent to prescribe or to provide advice regarding medication in post-bariatric surgery patients. Most of the respondents (95%) believed that other healthcare professionals should be aware of the contraindication "bariatric surgery". Of the respondents, 37% indicated that they were not aware of the medication advice incorporated in the electronic health record systems. Almost half of the respondents (48%) indicated that they documented changes in drug effects. Most respondents answered that these ought to be registered in the pharmacovigilance database or national registry.

CONCLUSIONS

The majority of prescribers and pharmacists believe that patients will receive better pharmacotherapy if healthcare professionals take MBS into account. However, not all prescribers think they are competent to act adequately. To improve this, information on changed drug effects after MBS should be more widely shared among healthcare professionals via resources that are easily accessible.

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.

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.

Patient and the Public's Perceptions of Bariatric Surgery: A Systematic Review

INTRODUCTION

Bariatric surgery is an effective therapeutic modality for obesity and related comorbidities, yet it remains significantly underutilized. Patient perceptions and expectations may influence the decisions of eligible patients in pursuing surgery.

METHODS

PubMed, SCOPUS, and OVID databases were searched in July 2022 to identify published studies discussing patient and the public's perceptions of bariatric surgery.

RESULTS

The literature shows participants often reported bariatric surgery to be a life-changing intervention known to induce weight loss, improve obesity-related comorbidities, and improve quality of life. However, a significant proportion of survey respondents perceived bariatric surgery as unsafe or risky. Patients belonging to racial minority groups cited higher concern with mortality risk, lower weight loss expectations, and different motivations to pursue bariatric surgery. Female patients were significantly more likely to have more positive perceptions of, and higher expectations of weight loss from, bariatric surgery.

CONCLUSIONS

The literature highlighted discordance between patient perceptions and the demonstrated clinical safety and efficacy profile of bariatric surgery. Overestimations of the risks, unrealistic expectations, and unfamiliarity with bariatric surgery outcomes were common findings. These perceptions of bariatric surgery may contribute to its underutilization among eligible patients. Perceptions and motivations often varied by race, region, sex, and age, which demonstrates the necessity of patient-centered education in the prereferral stage. The literature also demonstrated misconceptions of bariatric surgery among the public. Further research should explore the impact of education on the perceptions of patients and the public.

Knowledge and Attitudes Towards Obesity and Bariatric Surgery in University Students: a National Survey

BACKGROUND

Obesity has become a noticeable public health problem, especially in the young population. Bariatric surgery is growing in China but it is still new to the general public. Knowledge and attitudes towards obesity and bariatric surgery in university students are important to national health decision-making.

OBJECTIVES

To study the knowledge and attitudes towards obesity and bariatric surgery among Chinese university students.

METHODS

A self-designed questionnaire was distributed to university students to fill in online from June to July 2021.

RESULTS

A total of 3199 questionnaires were received, with an effective rate of 98.58% (3154 questionnaires). 65.44% of whom had normal BMI and 12.14% of whom were overweight or in obesity. More than 80% of them had a high knowledge of the common causes and complications of obesity but lacked knowledge of the relationship between obesity and bone and joint, tumor or cancer, and reproductive diseases. 51.55% of them thought they needed to lose weight, especially female students (P < 0.01). Only 39% had regular physical exercise habits, 58.62% of them could reasonably control their diet, and more than 2/3 of them (67.82%) often stayed up late. Safety (29.77%) and effectiveness (29.3%) of bariatric surgery were not well accepted. Among medical students, education positively affected knowledge and attitudes towards bariatric surgery (P < 0.05). Mass media and social platforms were the main sources for obtaining obesity and weight-loss information.

CONCLUSIONS

Chinese university students have insufficient knowledge of obesity and related complications, lack of scientific management of their own weight, and poor acceptance of bariatric surgery. More education is needed on this issue.

Management of Complications After Bariatric Surgery: a Survey of Comfort and Educational Needs of General Surgeons in Ontario, Canada

Purpose

Approximately 10% of patients develop complications after bariatric surgery. These patients often present to their local general surgeon rather than the hospital where the primary bariatric operation was performed. The objective of this study was to conduct a survey of general surgeons in Ontario, Canada, to explore their confidence and educational needs regarding management of surgical complications post-bariatric surgery.

Materials and Methods

A 40-item survey was created and piloted with community and academic general surgeons. It was disseminated by mail in August 2020 to general surgeons in Ontario who take acute care surgery call. Bariatric surgeons and surgeons who do not take acute care surgery call were excluded.

Results

A total of 138/715 (19.3%) eligible surgeons completed the survey. Of the respondents, 63/112 (54.3%) had no exposure to bariatric surgery during residency or fellowship. A total of 72/108 (66.7%) respondents agreed that management of complications after bariatric surgery should be within the skillset of a general surgeon; however, 28/108 (25.9%) were not confident managing these complications. Seventy-one of 108 (65.7%) respondents were interested in additional continuing professional development (CPD) resources regarding management of these complications. Hands-on workshops, online resources, and live webinars were the most preferred educational formats for such CPD resources, with 67.1% of participants willing to commit 1–3 h and 42.9% willing to pay >$100 for such CPD resources.

Conclusions

One-quarter of general surgeons in Ontario, Canada, were not comfortable managing complications after bariatric surgery; however, the majority of surgeons were interested in additional CPD resources on this topic.

Factors Associated With Bariatric Surgery Referral Patterns: A Systematic Review

INTRODUCTION

Bariatric surgery (BS) has been shown to effectively treat morbid obesity and improve obesity-related comorbidities. Nonetheless, BS remains underutilized among qualified patients.

MATERIALS AND METHODS

PubMed, SCOPUS, and OVID databases were searched to identify published comparative studies examining BS referral patterns. Data on barriers to BS referrals were examined and summarized.

RESULTS

Barriers to referrals stemmed largely from a lack of familiarity with safety, efficacy, and postoperative care amongst providers. Providers with previous referrals were more likely to report higher knowledge, comfort in referring patients, and ability to provide postoperative care. Provider initiated discussion of BS was positively associated with referrals. Female and younger patients were more likely to receive referrals. Furthermore, access to appropriate peri-operative resources, local bariatric programs, and insurance eligibility were associated with referral rates. Encouragingly, providers across specialties report eagerness to gain exposure and training in BS.

CONCLUSIONS

Lack of provider familiarity with BS efficacy, safety and postoperative care likely contributes to low utilization rates of BS. Further potential barriers in access to BS are logistic factors such as insurance coverage, limited local perioperative resources, and clinic time constraints for patient counseling. Promotion of BS amongst providers and both surgical and non-surgical trainees will likely have a significant impact on referral rates and access to this life-saving procedure. Future studies should further investigate the barriers to BS and delineate the effect size of each barrier on referral rates to efficiently increase access.

Awareness and Attitude of Surgeons regarding Dental Erosion on Patients Who Underwent Bariatric Surgery

Background

The obesity epidemic is considered one of the main challenges for modern medicine. It has been proven that bariatric surgery is more effective than nonsurgical interventions to manage weight-related comorbidities. The general surgeon needs to understand how tooth erosion advances in gastroesophageal reflux in people who have had bariatric surgery. Dental erosion caused due to gastric reflux begins with the enamel, which is the tough, protective coating that covers our teeth. While it is tough, it is prone to an extremely acidic environment with a low pH, where it begins to soften and demineralize, gradually wearing away and exposing the more sensitive areas of the tooth. Because of the growing popularity of this subspecialty, general surgeons should develop a basic clinical and surgical understanding of these standard procedures and complications, regardless of their interest in obesity surgery.

Aim

This cross-sectional study aimed to assess the awareness and attitude of surgeons regarding dental erosion on patients who underwent bariatric surgery.

Materials and Methods

This cross-sectional study was conducted on general surgeons from different regions of Saudi Arabia who perform bariatric surgeries. Data collection was done by sending the questionnaire to the general surgeons by different means of social media (WhatsApp, e-mail, Facebook, etc.), and it was also distributed through the Saudi Arabia Society of Metabolic and Bariatric Surgery.

Results

A total of 25 general surgeons responded to the survey. Half of the respondents know what dental erosion is, 52%. Most of them, 72%, are not aware of the relationship between dental erosion and acid reflux or vomiting. They reported that 52% of patients complain of gastroesophageal reflux disorder.

Conclusion

The general surgeons had inadequate awareness and attitude regarding dental erosion on bariatric surgery patients. Our findings suggest that a lack of adequate awareness and a negative attitude among general surgeons are grounds for concern and that more should be done to avoid oral health complications.

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.

Perceptions of Success in Bariatric Surgery: a Nationwide Survey Among Medical Professionals

INTRODUCTION

Various definitions for bariatric surgery (BS) success exist, with weight loss and comorbidity resolution outcomes being the most prominent. The study's aim was to compare how various healthcare professionals perceive success in BS.

METHODS

A 29-item, 10-point Likert scale online survey was distributed via email to Israeli healthcare professionals involved in the different BS aspects using common national professional organizations. These included bariatric surgeons, dietitians, social workers, psychologists, psychiatrists, primary care physicians, gastroenterologists, and nurses. Statement relevancy to BS success was rated. An item was classed as "very important" for BS success if at least 70% of participants rated it 8 or higher in each subgroup. Inter-observer agreement was calculated using kappa statistics. Data on specific occupation, years-in-practice, and major workplace were collected as well.

RESULTS

A total of 155 responses was obtained. The majority of respondents were dietitians (34.8%, n = 54), followed by bariatric surgeons (31.0%, n = 48) and nurses (14.8%, n = 23). Most respondents work mainly at public hospitals (32.9%, n = 51), followed by private hospitals (26.5%, n = 41). The mean years-in-practice among all healthcare professionals was 8.5 ± 8.5 years. Overall inter-observer agreement for prioritized items in accordance to BS success among all health professional subgroups was fair (Fleiss kappa = 0.278, P < 0.001), while dietitians and mental health specialists showed the highest agreement rate (Cohen's kappa = 0.592, P < 0.001).

CONCLUSION

The study highlights the various views on defining BS success by different healthcare professionals, although there was some overlap of core outcomes prioritized by all professionals. International uniform definitions for BS success are required.

Current knowledge and perception of bariatric surgery among Greek doctors living in Thessaly

INTRODUCTION

The purpose of this study was to assess doctors' knowledge, current conceptions, and clinical practice regarding obesity and bariatric surgery.

METHODS

A self-administered survey was administered to 500 doctors with varying medical specialties in public and private practice.

RESULTS

The response rate was 60%. Most participants (77.3%) were in private practice. Although almost half of the participants could define morbid obesity and obesity-related comorbidities, only 8.7% felt educated about bariatric surgery. Participants had little knowledge of various types of bariatric procedures. A minority of doctors (24.7%) knew of the existence of a bariatric center in their area. Only 21.3% of doctors had referred a patient to a bariatric center. Reasons for non-referral included lack of interest in bariatric surgery (37.3%), patient refusal (35.3%), increased operative fees (17.3%), lack of confidence in bariatric surgery (6.3%), and lack of access to a nearby bariatric center (3.7%). The majority of doctors were interested in learning more about bariatric surgery and related guidelines, but they remained reluctant to conduct patients' postoperative follow-ups.

CONCLUSION

The penetration of bariatric surgery in the medical community remains limited, despite its proven effectiveness in facilitating sustained weight loss and resolving several obesity-related comorbidities. A great effort should be made to inform health-care providers about the evolution of bariatric procedures, the potential benefits they offer, and the existence of certified bariatric centers. This will allow doctors to provide optimum health care to patients who could benefit from bariatric surgery.

A Landscape of Bariatric Surgery in Canada: For the Treatment of Obesity, Type 2 Diabetes and Other Comorbidities in Adults

Obesity has escalated worldwide and in Canada. Many chronic conditions, including type 2 diabetes, are directly correlated with obesity, and although the benefits and effectiveness of bariatric surgery have been proven in terms of sustained weight loss and improving comorbidities, the procedure is underaccessed and underutilized in Canada. We explored the complex landscape of bariatric surgery in Canada, reviewing the current state and focusing on the volume of procedures nationwide and at the provincial level, the type of surgical procedures performed, their outcomes and their associated complications. Barriers and challenges curbing access to bariatric surgery are also explored. Approximately 8,583 publicly funded bariatric surgeries were performed in 9 of 10 provinces in 2015/2016; Roux-en-Y gastric bypass, sleeve gastrectomy, adjustable gastric banding and biliopancreatic diversion with or without duodenal switch are the most common procedures performed, and coverage varies among provinces and territories. Dedicated bariatric programs have been created and, in some instances, provincial networks have also emerged. Weight loss, resolution of comorbidities and rates of complications in Canada are similar to those found in the literature. The increase in the number of bariatric procedures performed over time has still not met the current demand. The rise in obesity rates, the speed and regional variations in the development and standardization of processes, adequate patient selection, funding and prioritization and gaps in knowledge and attitudes about the merits of bariatric surgery of patients, health providers and policy makers create considerable waiting times and are some of the barriers to better access to bariatric surgery.

Optimizing Bariatric Surgery Multidisciplinary Follow-up: a Focus on Patient-Centered Care

BACKGROUND

Failure to follow-up post-bariatric surgery has been associated with higher postoperative complications, lower percentage weight loss and poorer nutrition.

OBJECTIVE

This study aimed to understand the patient follow-up experience in order to optimize follow-up care within a comprehensive bariatric surgery program.

METHODS

Qualitative telephone interviews were conducted in patients who underwent surgery through a publically funded multidisciplinary bariatric surgery program in 2011, in Ontario, Canada. Inductive thematic analysis was used.

RESULTS

Of the 46 patients interviewed, 76.1 % were female, mean age was 50, and 10 were lost to follow-up within 1 year postsurgery. Therapeutic continuity was the most important element of follow-up care identified by patients and was most frequently established with the dietician, as this team member was highly sought and accessible. Patients who attended regularly (1) appreciated the specialized care, (2) favoured ongoing monitoring and support, (3) were committed to the program and (4) felt their family doctor had insufficient experience/knowledge to manage their follow-up care. Of the 36 people who attended the clinic regularly, 8 were not planning to return after 2 years due to (1) perceived diminishing usefulness, (2) system issues, (3) confidence that their family physician could continue their care or (4) higher priority personal/health issues. Patients lost to follow-up stated similar barriers.

CONCLUSION

Patients believe the follow-up post-bariatric surgery is essential in providing the support required to maintain their diet and health. More personalized care focusing on continuity and relationships catering to individual patient needs balanced with local healthcare resources may redefine and reduce attrition rates.
