Factors influencing primary care provider referral for bariatric surgery: Systematic review

Factors Influencing Referral for Bariatric Surgery by Primary Care Physicians in Northern Israel

PURPOSE

Obesity is a chronic metabolic disease with global distribution among adults and children which affects daily functioning and ultimately quality of life. Primary care physicians (PCPs) provide an important role for the treatment of severe obesity. Better understanding of obesity and its treatment options may increase patients' referral rates to the various treatment modalities, including metabolic/bariatric surgery (MBS).

MATERIALS AND METHODS

A quantitative cross-sectional study used a self-reported questionnaire among PCPs of Clalit Health Services (CHS) in Northern Israel. The quantitative questionnaire examined the PCP's knowledge, opinions, attitude, and approaches to managing severe obesity.

RESULTS

A total of 246 PCPs from Northern Israel filled the questionnaire (42.9%), the majority were Muslim Arabs (54.5%), who gained their medical degree outside of Israel (73.8%) and practicing for over 10 years (58.8%). 64.3% of PCPs had a high workload (over 100 appointments per week), 77.1% did not know the definition of severe obesity, and 69.17% did not attend educational meetings regarding obesity during the previous year. The referral rate for MBS was 50.4% ± 23.3. Two prognostic factors that had a statistically significant effect on the referral rate for bariatric surgery were the total appointments per week, and the number of practice years. Both had a negative association.

CONCLUSION

The knowledge and referral rates for bariatric surgery are higher among PCPs with lower workload and relatively fewer practice years. Workshops and annual training courses may fortify knowledge and awareness for the treatment of obesity, which in turn could increase the referral rate for MBS.

A comprehensive analysis of health care Inequities in randomized clinical trials following bariatric surgeries

BACKGROUND

Obesity is a global epidemic, leading to an increasing focus on interventions like bariatric surgeries. Despite this, there's a noticeable gap in understanding the demographic distribution of patients in clinical trials for bariatric surgery.

METHODS

We conducted a comprehensive analysis of 117 registered randomized clinical trials related to bariatric surgery on ClinicalTrials.gov. We extracted demographic information, including age, sex, race, and ethnicity, and performed descriptive statistical analyses.

RESULTS

The analysis covered 8,418 participants. The mean age was 43.8 years, with a substantial majority (93.8 ​%) falling within the 18-65 age group. Females comprised 74.9 ​% of participants, surpassing real-world estimates. Racially, 65.3 ​% of participants were White, while African Americans represented 18.5 ​%, Asians 1.2 ​%, Native Hawaiians 0.2 ​%, and American Indians 0.1 ​%, indicating an underrepresentation of diverse racial groups, notably lower compared to real-world demographic data. In terms of ethnicity, only 17.6 ​% were Hispanic.

CONCLUSIONS

This study reveals significant demographic disparities in patients undergoing bariatric surgeries in clinical trials. This suggests a lack of generalizability, emphasizing the need for inclusive recruitment strategies to enhance health equity.

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.

Using Administrative Data in Primary Care to Evaluate the Effectiveness of a Continuing Professional Development Program Focused on the Management of Patients Living With Obesity

INTRODUCTION

There are guidelines for referral to medical and/or surgical weight loss interventions (MSWLI) in Ontario; however, only about one-third of eligible patients in our region are being referred for consideration of MSWLI.

METHODS

A planning committee, including a registered dietician, psychiatrist, endocrinologist, bariatric surgeon, family physician, and educationalists, developed an interdisciplinary continuing professional development (CPD) program focused on practical approaches to the management of patients living with obesity. The Kirkpatrick model was used to evaluate the educational outcomes of the CPD program specifically focusing on Level-2, -3, and -4 outcomes based on self-reported questionnaire and health administrative data.

RESULTS

Eighteen primary care providers from the CPD program agreed to participate in this study, and 16 primary care providers (89%) completed the postintervention questionnaire and granted us access to their MSWLI referral data; 94% of study participants reported changes to their knowledge, comfort, and confidence (Level 2), as well as expected change in their future behaviour (Level 3) following the CPD program. However, there was no change in Kirkpatrick Level-4 outcomes, despite more than 90% of participants indicating that they will be making changes to their practice after the program.

DISCUSSION

The CPD program in our study was overwhelmingly well received and participants reported knowledge (Level 2) and behavioural (Level 3) changes following participation; however, there was no detectable change in their clinical practice (Level 4). The methodology described in our proof-of-concept study can be modified and adopted to evaluate Level-4 outcomes in other studies of effectiveness of CPD interventions.
