Factors Associated With Bariatric Surgery Referral Patterns: A Systematic Review.

Bariatric surgery (BS) has been shown to effectively treat morbid obesity and improve obesity-related comorbidities. Nonetheless, BS remains underutilized among qualified patients. 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. 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. 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. • Provider familiarity with bariatric surgery (BS) is associated with referrals. • Provider perception of BS safety and efficacy is inconsistent with the literature. • Provider initiated discussion of surgery is associated with increased referrals. • Paperless referrals and billing for counseling may increase referral rates. • Providers across specialties are eager to learn more about bariatric patient care.
