Noting that only about 1% to 2% of people who are eligible for bariatric or metabolic surgery actually undergo the procedures, Kahan said, “because so few people get the surgery we’ve never really run into a situation of undersupply or over-demand.”
“But, as we’re moving forward, one would think that we will run into that scenario. So, better prioritizing and triaging patients likely will be more important down the line, given how effective surgery has been shown to be now, both short-term and long-term.”
Risks of Obesity, Shifting Away From BMI as the Main Metric
The new document extensively discusses the risks of obesity — including now as a major COVID-19 risk factor — and the benefits of the procedures and risks of delaying them.
It also addresses ongoing management of patients who had bariatric/metabolic surgery in the past and nonsurgical treatment to mitigate harm until patients can undergo the procedures.
Another important problem the document addresses, Rubino said, is the current BMI-focused bariatric/metabolic surgery criteria (≥ 40 kg/m2 or ≥ 35 kg/m2 with at least one obesity-related comorbidity).
“BMI is an epidemiological measure, not a measure of disease. But we select patients for bariatric surgery by saying who is eligible [without assessing] who has more or less severe disease, and who is at more or less risk for short-term complications from the disease compared to others,” he explained.
“We don’t have any mechanism, even in normal times, let alone during a pandemic, to differentiate between patients who need surgery sooner rather than later.”
Indeed, Kahan said, “Traditionally we tend to oversimplify risk stratification in terms of how heavy people are. While that is one factor of importance, it’s far from the only factor and may not be the most important factor.”
In “someone who is relatively lighter but sicker, it would be sensible, in my mind, to prioritize them for a potentially curative procedure compared with someone who is heavier — even much heavier — but is not as sick,” he added.
