Comparison of public and private bariatric surgery services in Canada.

BACKGROUND

Surgical treatment of obesity is cost-effective and improves life expectancy. Roux-en-Y gastric bypass (RYGB) and adjustable gastric banding (AGB) are dominant surgical techniques, but RYGB is the only publicly insured procedure in all Canadian provinces. Private clinics currently offer AGB with minimal wait times. We sought to compare RYGB in public facilities with AGB in private clinics in terms of cost, wait times and certain aspects of patient care.

METHODS

We conducted telephone interviews of all bariatric surgery providers across Canada (100% response rate). We asked about various aspects of care, such as wait time, cost, pre- and postoperative care and surgeon experience.

RESULTS

The median out-of-pocket cost for AGB at private facilities is $16,000 (range $13,160-$18,375). Private clinics have much shorter wait times for AGB than public facilities do for RYGB (1 v. 21 mo, p < 0.001). Private clinics provide significantly fewer preoperative visits with multidisciplinary health professionals (2.7 v. 4.3, p = 0.045), and 5 of 12 (42%) private clinics conduct AGB surgeries without on-site critical care for high-risk (based on the respondents' definitions) patients.

CONCLUSION

Private clinics performing AGB offer short wait times, but the cost is high. We found a great deal of variation between pre- and postoperative care among bariatric surgery facilities, and in some cases patient care appears to be less comprehensive. Our findings suggest that further research on obesity treatment is needed to inform policy so that all Canadians can have equitable and timely access to proven, evidence-based care.
