|Brief Title ICMJE||Children With Asthma in New Orleans After Hurricane Katrina|
|Official Title ICMJE||Head-Off Environmental Asthma in Louisiana|
This study will examine whether exposure to the increased levels of mold and other allergens in New Orleans post-Hurricane Katrina affect symptoms in children with asthma. It will also determine if having an asthma counselor (AC) can reduce a child s asthma symptoms in this setting. An AC helps the families in the study obtain appropriate health care, medicines and social services for their asthmatic child and instructs them about avoiding allergens and ridding allergens from the home.
Children between 4 and 12 years of age living in Orleans Parish or surrounding areas impacted by flooding who have moderate to severe asthma may be eligible for this study.
Parents provide a family medical history and information about the child s asthma symptoms, medications and medical history. The children undergo the following procedures:
Study staff visit the participants homes three times during the 1-year study to test for moisture, mold and other allergens. After the first visit, families are randomly assigned to one of two groups. Group 1 participants attend two educational group sessions about asthma and then three individual sessions. An AC visits the home one time during the study to instruct the family on how to use supplies provided to reduce allergens in the home. Group 2 participants have an individual special teaching meeting with the AC at the end of the study. After the meeting, the AC visits the home to instruct the family on use of the supplies.
Families are surveyed by phone every 3 months during the study to answer questions about the child s asthma attacks, medicines used, doctor visits, school days, missed, or work days missed to care for the child. At the end of the study, the child has a final medical examination, blood test, and breathing test.
This document presents the protocol for conducting the Head-off Environmental Asthma in Louisiana (HEAL) study in New Orleans, Louisiana. The goal of the HEAL study is to implement and test an Asthma Counselor (AC) intervention program that addresses the multidimensional impact of hurricane Katrina on children with asthma in New Orleans. HEAL is a prospective, controlled trial in which children will be randomly assigned to one of two treatment groups. Group 1 children will receive an AC intervention focused on case management, adherence to medications and education on allergen avoidance. The responsibilities of the AC in this study are enhanced relative to previous initiatives such as the National Cooperative Inner City Asthma Study (NCICAS) AC intervention to also provide families with education aimed at reducing mold, allergens, and moisture in their homes, and materials to aid this effort (dehumidifiers and HEPA air filters). Since 90% of children with asthma in New Orleans are sensitive to dust allergens, established allergen control measures will be incorporated into the AC intervention as well. Group 2 children will receive a high quality standard of care based on the National Asthma Education and Prevention Program (NAEPP)-NIH guidelines. An abbreviated AC intervention will be provided to children in Group 2 at the conclusion of the study. Both treatments will be administered over a 12-month period during which the children in both groups will receive an extensive clinical evaluation (at baseline and 12-months) and three environmental home evaluations (focused on moisture, mold and other allergens). In addition to monitoring the effectiveness of the AC at environmental remediation education, the environmental home evaluations will also allow some characterization of the relationships between allergens, post-Katrina environmental exposures and asthma morbidity.
In addition to the enhanced AC intervention, a separate school based survey will be administered to a sample population of children to examine asthma prevalence and assess living conditions and stress levels that may have been influenced by hurricane Katrina. The survey population will consist of a sample of the families of Orleans Parish school children stratified by age, schools and geographic area of the Parish. The results of the survey, in combination with the results of the AC intervention, will give us an overview of the extent and severity of the asthma problem in post hurricane Katrina New Orleans.
The HEAL project is a collaborative multi-institutional research project conducted by the Tulane University School of Public Health and Tropical Medicine and the New Orleans Department of Health. To support those efforts, Rho, Inc. will provide for coordination of data and study activities.

A child will be included in the HEAL intervention study if he or she:
3a. Evidence of persistent asthma as defined by the National Asthma Education and Prevention Program (NAEPP) of the National Heart Lung and Blood Institute Expert Panel Report 2: Guidelines for the Diagnosis and Management of Asthma (1997), which includes: asthma symptoms 3 or more days per week during the last two weeks, sleep disturbed due to asthma at least 3 times in the past month, or albuterol use (Metered Dose Inhaler or nebulizer) for quick relief at least 8 times in the past two weeks, not including use as a preventive for exercise.
3b. Evidence of uncontrolled disease as defined by at least one of the following additional criteria:
i. One asthma-related unscheduled visit to an emergency department (ED), urgent care (UC), or clinic in the previous 12 months.
ii. One asthma-related overnight hospitalization in the previous 12 months.
iii. One or more bursts of oral corticosteroids or equivalent in the previous 12 months.
4) Has a parent or legal guardian willing to sign the written informed consent prior to initiation into the study.
5) Is willing to sign the assent form, if age appropriate.
A child will be excluded from the HEAL intervention study if she or he:
One child from each household will be selected to participate in the study. In the case of multiple eligible children, the youngest child will be included in the study.
