Healthy People 2010

The U.S. Department of Health and Human Services has developed Healthy People 2010 – a set of disease prevention and health promotion objectives for the nation to achieve over the first decade of the new century. Michigan has had some success in reaching certain asthma objectives for some groups. Click for more information about Healthy People 2010.

The Healthy People 2010 Objectives for Asthma

  • Reduce hospitalization rates for pediatric asthma.

  • Reduce asthma deaths.

  • Reduce hospitalizations for asthma.

  • Reduce emergency department visits for asthma.

  • Reduce activity limitations among persons with asthma.

  • Reduce the number of school or workdays missed by persons with asthma due to asthma.

  • Increase the proportion of persons with asthma who receive formal patient education.

  • Increase the proportion of persons with asthma who receive appropriate asthma care according to the NAEPP Guidelines. Including:
    • written asthma management plans from health care provider.

    • instruction on how to use a prescribed inhaler properly.

    • education about recognizing early signs and symptoms of asthma episodes and how to respond properly, with lessons on peak flow monitoring for those using daily therapy.

    • medication regimens that prevent the need for more than 1 canister of short acting inhaled beta agonists per month for relief of symptoms.

    • follow-up medical care for long-term management after a hospitalization due to asthma.

    • assistance with assessing and reducing exposure to environmental risk factors.
  • Michigan is showing success in meeting the target asthma hospitalization rates overall and among whites.
  • Conversely, asthma hospitalization rates for blacks ages 5 to 64 are not moving closer to the Healthy People 2010 target.
  • Recent data shows that the asthma hospitalization rate for persons age 5 to 64 years is lower than the Healthy People 2010 target rate in 15 counties: Chippewa, Emmet, Grand Traverse, Ionia, Isabella, Kalkaska, Lapeer, Livingston, Manistee, Marquettte, Mason, Mecosta, Osceola, Ottawa, and Wexford.

  • The most recent death rates indicate that Michigan has met the target rate for adults age 65 years and older.

  • Despite these results, there remains a striking difference in asthma hospitalization rates between whites and blacks of Michigan. Efforts to reduce the burden of asthma in Michigan must address this issue.

  • Between 1990 and 2004, there has been a significant drop in asthma hospitalization rates for children in Michigan, toward the Healthy People 2010 target rate.
  • Between 1990 and 2004, there was a significant overall drop in asthma hospitalization rates for whites in Michigan age 5 to 64 years. No such drop is observed for blacks in this age group.
  • For adults age 65 years and older, asthma death rates have met the Healthy People 2010 target rate in recent years.

Healthy People 2010 Target for Objective 24-2, Age 5 to 64 Years, Michigan, 1990 to 2002.

1Population estimates are taken from the Michigan annual population estimates, 1990-2002.
2Rates are age adjusted to the 2000 US standard population by the direct standardization method. 
Hospitalization records with missing age are excluded.
 3Asthma hospitalization defined as a primary discharge diagnosis of asthma, ICD-9-CM=493.XX.
4For records that are missing data on race, race was assigned based on the 1990 census population (a990-2002) or the hospitalized population (2003, 2004).
5Insufficient data to compute a stable rate for races other than white or black.
