Obesity treatment analysis advisory group

To assist in this effort, our office has contracted with Milliman, Inc. and the Washington State Institute for Public Policy (WSIPP).

Milliman, Inc. will perform an actuarial analysis that includes, but is not limited to, a utilization and cost analysis of each of the following services:

• Intensive health, behavioral, and lifestyle treatment;
• Metabolic and bariatric surgery; and 
• Food and Drug Administration-approved obesity medication.

WSIPP will analyze and evaluate the effect of identified weight loss treatments on obesity, weight loss, and/or diabetes, and will use WSIPP's benefit-cost model to monetize effect sizes.

Given the complexity and clinical issues related to a potential obesity treatment benefit, our office has formed the Obesity Treatment Analysis Advisory Group. Members of the advisory group have experience and expertise that will help inform our work.
