Provincial Variation in Accessibility to Bariatric Surgery

>> Saturday, May 15, 2010



At the Inaugural Diabetes Surgery Summit in Montreal last week, it became apparent that there is significant provincial variation in accessibility to weight loss (bariatric) surgery. As Dr. Nicolas Christou of McGill University pointed out, in Canada in 2008, the number of bariatric surgeries performed in each province was as follows:

- Nova Scotia: 28
- New Brunswick: 17
- Quebec: 802
- Ontario: 579
- Saskatchewan: 23
- Alberta: 272
- BC: 160

The reasons for the provincial variation are complex. One interesting phenomenon that was brought up was that in Ontario, patients had previously been funded by the provincial health care system to have bariatric procedures done in the United States - this was a situation that was unique to Ontarians, as no other province provided funding to do this. Due to the enormous expense of sending patients over the border and the potential savings of having these surgeries done at home, the Ontario government provided funding to build access to the service in their home province, to the tune of many millions of dollars in cost savings. As other provinces never had the situation where patients were funded to go south to have surgery, the same financial pressure does not exist to bring the procedure home.

In the mix of the numbers above, other factors have to of course be considered, including population density and surgical expertise available in each province (though with increased provincial funding for bariatric surgery, the surgical expertise would be likely to follow).

Even in provinces with the most accessibility to surgery, however, there is still an enormous shortage of availability country wide, with an estimated fifteen year backlog of patients who would be appropriate for, and benefit from, the surgery.

What can we do? Get out there and talk about it.

Diabetes Treatment - is Weight Loss Surgery the Answer?

>> Saturday, May 8, 2010




Canada, like the rest of the world, is caught in a diabetes epidemic. Over 2 million Canadians are diagnosed with the disease, and by the year 2020, those numbers are expected to rise to 3.7 million. This epidemic is paralleled by the high prevalence of obesity, which currently affects 25% of Canadian adults and 10% of Canadian children. One of the treatment options that is being increasingly considered to treat type 2 diabetes in the setting of severe obesity is weight loss surgery.

I attended the First Canadian Diabetes Surgery Summit in Montreal this week, hosted by McGill University, to discuss this very issue. Over two very intense and productive days, a collection of international leaders in the area presented their research and clinical experience to a diverse group including Canadian surgeons, family physicians, endocrinologists, health care professionals, and policy makers. A wealth of learning, sharing, and ideas were generated from this summit, of which I am going to discuss over the course of several articles in the coming weeks. Here are the highlights.

In short, bariatric surgery is a very effective treatment for type 2 diabetes. The results depend on the type of surgery done, but remission rates of diabetes of over 80% have been documented, and sustained for at least 2 years. Much of this success is related to the impressive weight loss that is seen with bariatric surgery, but gut hormone changes with certain types of surgery (such as gastric bypass surgery) play an important role as well.

It must be emphasized that bariatric surgery is only appropriate for a very select group of people. The current guidelines recommend bariatric surgery as a potential option for patients with a BMI >40, or a BMI >35 with at least one serious medical complication (such as diabetes), who have failed intensive attempts at weight loss with conventional treatments (lifestyle alteration, medications, etc). Bariatric surgery has a long list of potential side effects and complications that must be seriously considered, and which vary depending on the type of surgery performed. On balance, however, bariatric surgery has been shown to decrease mortality by 28-40% in this population, and as such, may be the most appropriate option for some people.

In Canada, we struggle with very limited accessibility to bariatric surgery. As Dr. Nicolas Christou, one of Canada's leaders in bariatric surgery, pointed out:
  • Based on very conservative estimates that 5% of the 1 million Canadians who fit criteria for bariatric surgery would actually be appropriate candidates for surgery, 50,000 Canadians would currently be candidates for the procedure.
  • Approximately 3,000 bariatric procedures will be done in Canada this year.
  • According to these numbers, then, Canada currently has in excess of a 15 year back log of patients who could benefit from these procedures.

What can we do about this? The problem of course, is funding. Funding for bariatric surgery is extremely limited in Canada, though accessibility does vary greatly by province. Cost analyses suggest that for patients with diabetes, the costs of bariatric surgery to the government are recouped by 26-30 months post operatively, and after that, there are only savings to be had by the health care system due to the decreased rate of diabetes related complications, hospitalizations, and medication requirements of these patients. 

On balance, increased accessibility to bariatric surgery in Canada, provided in the appropriate clinical setting by a multidisciplinary, experienced health care team, should be discussed amongst Canadian health care professionals, patients, and the general public.
