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

To identify barriers to and facilitators of primary care provider (PCP) referral for bariatric surgery in patients with obesity.

MEDLINE, EMBASE, and PsycINFO databases were searched and reference lists of included articles were screened to identify additional relevant articles. Two reviewers independently reviewed citations and full-text articles, and appraised the quality of the included articles using the Critical Appraisal Skills Programme Tool Qualitative Checklist and the Appraisal Tool for Cross-Sectional Studies. They extracted data on the study characteristics and the barriers to and facilitators of PCP referral for bariatric surgery. Appraisal discrepancies were resolved through consensus among authors.

Overall, 882 citations were identified and 18 articles were then selected for this review.

Barriers included fear of surgery complications and side effects, cost, lack of availability, perception that surgery is a quick fix or a last resort, and prior negative experiences. Facilitators included direct requests from patients, patient motivation, previously failed weight-loss interventions, and obesity-related comorbidities. Those PCPs who were knowledgeable about the risks and benefits of bariatric surgery were more likely to refer their patients.

Education and continuing professional development programs regarding bariatric surgery are needed to improve PCP knowledge and capacity to manage patients with obesity. Also, educating the general public on obesity, weight management, and available treatment options can empower patients and families to manage their weight and pursue evidence-informed treatments.
