### Measure Domain

#### PRIMARY MEASURE DOMAIN

Process

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
Validity](http://www.qualitymeasures.ahrq.gov/resources/measure_domains.aspx)
page.

#### SECONDARY MEASURE DOMAIN

Does not apply to this measure

### Brief Abstract

#### DESCRIPTION

This measure is used to assess the percentage of patients aged 65 years
or older who received at least one influenza vaccine in the past two
years.

#### RATIONALE

Provincial guidelines recommend that all adults aged 65 years or older
receive annual influenza vaccinations.  Despite Manitoba Health\'s
public campaign as well as evidence that the influenza vaccination has
significant impact on mortality rates among those 65 and older, over
one-third of older adults are not being vaccinated.

#### PRIMARY CLINICAL COMPONENT

Influenza; vaccination

#### DENOMINATOR DESCRIPTION

Patients aged 65 years or older assigned to a family physician (see the
related \"Denominator Inclusions/Exclusions\" field in the Complete
Summary)

#### NUMERATOR DESCRIPTION

Number of patients from the denominator who received at least one
influenza vaccination in the past two years

### Evidence Supporting the Measure

#### EVIDENCE SUPPORTING THE CRITERION OF QUALITY

-   A clinical practice guideline or other peer-reviewed synthesis of
    the clinical evidence

-   A formal consensus procedure involving experts in relevant clinical,
    methodological, and organizational sciences

-   Focus groups

-   One or more research studies published in a National Library of
    Medicine (NLM) indexed, peer-reviewed journal

### Evidence Supporting Need for the Measure

#### NEED FOR THE MEASURE

Use of this measure to improve performance\
Variation in quality for the performance measured
