Overview
Summary: This webinar will review the comprehensive outpatient management of asthma with the goals of improving asthma control and enhancing employability. This course is offered at an intermediate level. It will consist of lecture, a pre-test, post-test and a question and answer period. No prerequisite knowledge is required for this course.

Learning Objectives
After this presentation, participants will be able to: Describe the current National Heart Lung and Blood
Institute (NHLBI) Asthma Guidelines for classifying severity, control, and stepwise management of asthma.
Apply updated Job Corps Treatment Guidelines for management of students with asthma.
Implement case management for all Job Corps students with asthma.

Fast Facts
Every day in America:40,000 people miss school or work due to asthma 30,000 people have an asthma attack 5,000 people visit the emergency room due to asthma 1,000 people are admitted to the hospital due to asthma 11 people die from asthma

Key Points In 2009, the prevalence of asthma increased to 7.7% among adults, 9.6%
among all children, and 17.0% among black, non-Hispanic children. In 2008, approximately half of persons with asthma reported having had at
least one asthma attack during the preceding 12 months. Medical expenses associated with asthma amounted to $3,259 per person per
year during 2002--2007. Good control of asthma includes self-management training, appropriate use
of inhaled corticosteroids to prevent symptoms and attacks, and avoidance of environmental allergens and irritants. However, only approximately one third of persons with asthma had been given an asthma action plan as recommended.

Asthma Mortality Each day 11 Americans die from asthma. There are more than 4,000 deaths due to
asthma each year, many of which are avoidable with proper treatment and care. In addition, asthma is indicated as “contributing factor” for nearly 7,000 other deaths each year.
Since 1980, asthma death rates overall have increased more than 50% among all genders, age groups and ethnic groups. The death rate for children under 19 years old has increased by nearly 80% percent since 1980.
More females die of asthma than males, and women account for nearly 65% of asthma deaths overall.
African Americans are three times more likely to die from asthma. African American women have the highest asthma mortality rate of all groups, more than 2.5 times higher than Caucasian women.

Gonzalez v. Hanford Elementary School District
Jury Awards $9 million in Asthma Death at School
“A California jury that unanimously awarded a mother $9 million in damages for the death of her 11 year-old son from an asthma attack at school found the school district guilty of negligence for failing to inform parents of an unwritten school policy that would have allowed the child to carry an inhaler.”

all patients with persistent asthma require both classes of medication

Asthma Medication: Patient Concerns
fear of addiction belief that efficacy diminishes with long-term use confusing corticosteroids with anabolic steroids fear of side effects confusing preventive therapy with acute treatment of
symptoms
![Page 35: Webinar: Managing Asthma in the Job Corps Student](https://reader035.vdocuments.net/reader035/viewer/2022062500/568150c4550346895dbee44d/html5/thumbnails/35.jpg)
Quick Relief: Steps 1-6
short-acting bronchodilator: inhaled 2 agonists as need for symptoms
intensity of treatment depends on severity of exacerbation – up to 3 treatments at 20 minute intervals
increasing use of short-acting inhaled 2 agonists indicates the need for initial or additional long-term control therapy
![Page 36: Webinar: Managing Asthma in the Job Corps Student](https://reader035.vdocuments.net/reader035/viewer/2022062500/568150c4550346895dbee44d/html5/thumbnails/36.jpg)
