Weight Loss Surgery Trends Update 2016

We have recently analyzed our 2016 weight loss surgery patient data. In this post we will discuss patient demographics and trends. To read about our 2016 gastric sleeve patient outcomes, click here.

Of note, Dr. Oliak is a private practice weight loss surgeon located in Orange County, California, so his data and the patient trends he has observed might not be comparable to surgeons in other geographic locations and practice situations.

Weight Loss Surgery Demographics 2016

See our 2016 weight loss surgery patient demographics in the table below:

See payer details for our 2016 patients in the table below:

[table id=8 /]

Gender distribution, average age, age range, average BMI, and BMI range for our 2016 patients are all fairly consistent with the numbers from previous years. Females typically comprise 2/3 to 3/4 of patients, age spans a wide range (16-70 generally) but the average is typically 42-45, and average BMI typically is in the low 40’s but also spans a wide range (30-70 generally).

Weight Loss Surgery Trends 2016

What is most interesting in the tables above are the increase in gastric sleeve surgeries and revisions in 2016, and the increase in private pay patients in 2016.

The gastric sleeve operation has been growing in popularity for several years, but 2016 proved to be the year during which the gastric sleeve has almost completely taken over. During 2016 we did only 3% gastric bypass operations, and no LAP-BAND® operations.

LAP-BAND® revision operations to either gastric sleeve or gastric bypass also increased in frequency last year. Because the main issue with the LAP-BAND® operation is an increase in complications as time goes on, we anticipate the number of revision operations to increase over the next several years.

Finally, we have noticed a significant change in the payer mix over the past year. Insurance companies have made getting an approval for weight loss surgery more difficult, and therefore, more patients are electing to not use insurance and pay for surgery themselves.

The percentage of private pay patients in our practice has been relatively constant at 30-35% over the 5 years from 2011-2015, but has increased to 46% of overall patients in 2016. This correlates with what we noticed to be much more stringent requirements for insurance authorizations in 2016.

To conclude, our data shows that the weight loss surgery trends of 2016 were the continued increase in popularity of the gastric sleeve operation over the alternative operations, and the increase in private pay patients due to increased insurance barriers to getting insurance authorization for weight loss surgery.
