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

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.
