#### PRIMARY MEASURE DOMAIN

Use of Services

The validity of measures depends on how they are built. By examining the
key building blocks of a measure, you can assess its validity for your
purpose. For more information, visit the [Measure

### Brief Abstract

#### DESCRIPTION

This measure is used to assess the percent of enrollees with a screening
and/or prevention encounter with the diagnosis for overweight or
obesity.

#### RATIONALE

Obesity is linked to increased risk for diabetes, hypertension, heart
disease, disability and adverse outcomes of pregnancy, including
prematurity and increased maternal and infant mortality.

Costs associates with dealing with the effects of obesity are increasing
as its prevalence increases. Demand for the most costly intervention,
bariatric surgery such as gastric bypass, has tripled in recent years.
Demand for the procedure to surgically remove excess tissue after weight
loss, called pannicutectomy, has also increased.

Recent research indicates the post-operative complication rate for
bariatric surgery is significantly higher than previously thought, and
the costs associated with post-operative complications in the first year
after surgery are substantial. For example, 4 out of 10 bariatric
surgery patients have complications within six months of discharge. Risk
for adverse health outcomes are therefore also higher than previously
believed. Being a Medicaid recipient has also been shown to increase the
risk of post-operative mortality.

Patients insured through Medicaid had nearly 5 times the risk of dying
than privately insured patients, and those requiring re-operation were
at 22 times higher risk of dying.

Policy options to deal with the problem by shifting resources away from
invasive interventions and to prevention and non-surgical interventions
are necessary to improve patient safety, improve quality of care,
quality of life and avoid preventable excess costs associated with
obesity.

#### PRIMARY CLINICAL COMPONENT

Obesity; morbid obesity; overweight; screening; prevention

#### DENOMINATOR DESCRIPTION

Medicaid/BadgerCare enrollees in each age cohort (ages 6 to 10 years, 11
to 17 years, and over age 18 years) continuously enrolled with the same
health maintenance organization (HMO) for at least 304 days immediately
prior to the measure end date with no more than one gap in enrollment of
not more than 45 days. The enrollee must have a total of not less than
259 enrolled days in the look-back period (see the \"Description of Case
Finding\" field in the Complete Summary).

#### NUMERATOR DESCRIPTION

Enrollees in the denominator with a screening and/or prevention
encounter with a diagnosis code for obesity, morbid obesity, or
overweight

**Note**: Refer to the original measure documentation for specific
administrative codes used to define screening/prevention encounters and
a diagnosis of obesity, morbid obesity, or overweight.

#### STRATIFICATION BY VULNERABLE POPULATIONS

Three age cohorts are reported for this measure, including low-income
children (ages 6 to 10 years, 11 to 17 years, and 18+).

### Characteristics of the Primary Clinical Component

#### INCIDENCE/PREVALENCE

The National average for prevalence of overweight or obesity among
children age 6 to 19 years of age in 2000 was recently estimated at
approximately 11 percent. The same report cited an estimated prevalence
of 23 percent among adults over age 19 years nationwide. These
percentages are based only on age-adjusted estimates and subjective
survey data. Data from the Centers for Disease Control and Prevention
(CDC) NHANES survey estimated obesity among children age 12 to 19 years
of age to be 16 percent.

CDC data estimates the prevalence of obesity among Wisconsin adults at
21.9 percent.

Prevalence of diagnosed overweight, obesity or morbid obesity in all age
cohorts was 6.2 percent, with adults being diagnosed more than twice as
frequently as children.

In 2006, the average period prevalence for encounters with a diagnosis
of obesity among children age 6 to 10 years old was 2 percent. Among
children age 11 to 17 years, the average period prevalence was 3.5
percent (n=2,167) and 8.5 percent (n=8,133) among adults 18 and over.

**Note** that CDC data are estimates based on consumer self-report and
survey data, not objective clinical data. The Wisconsin Medicaid
MEDDIC-MS Obesity Prevention and Treatment data is based on actual
encounter data.

#### UTILIZATION

Among those Wisconsin Medicaid enrollees with a formal diagnosis of
overweight or obesity, on average, three out of four received a
screening or preventive service, including dietary or nutritional
counseling. That percentage was nearly identical for children and
adults. Comparable national data is not available.
