Learning Objectives for this Presentation:
By the end of the presentation participants will be able to describe the impact of the 2000 ACIP flu shot recommendations on a composite measure of clinical preventive service delivery to adults ages 50-64.

Background:
In 2000 the Advisory Committee on Immunization Practices recommended annual influenza vaccinations for adults ages 50-64. The addition of this intervention expanded the number of routine clinical preventive services recommended to these adults.

Objectives:
To assess the impact of recommending influenza vaccinations for U.S. adults ages 50-64 on a composite measure of clinical preventive service delivery

Methods:
We analyzed state data from the 1997 and 2002 Behavioral Risk Factor Surveillance Survey and included, respectively, 24,917 and 55,366 respondents ages 50-64. We created a composite measure that included colonoscopy or sigmoidoscopy within 10 years or fecal occult blood test in the past year, influenza vaccination in the past year (2002 only), Pap test within 3 years for women with an intact cervix, and a mammogram within two years. The composite measure quantifies the percent of adults who are up-to-date with recommendations for these services.

Results:
Despite increases in the delivery of each of the recommended routine clinical preventive services to men and women ages 50-64 between 1997 and 2002, there was a significant decrease in the composite up-to-date measure of clinical preventive delivery. The percent of men ages 50-64 who received the recommended services decreased from 37.6% (1997) to 21.4% (2002); the percent of women ages 50-64 receiving these services decreased from 30.5% (1997) to 21.1% (2002). For uninsured men and women ages 50-64, between 1997 and 2002 the composite measure decreased, respectively, from 23.1% to 7.9% and from 15.8% to 7.8%.

Conclusions:
The composite measure of clinical preventive service delivery decreased significantly in 2002 for adults ages 50-64 as a result of newly recommended flu shots for this age group.
