|This is a randomized controlled trial of a clinician and parent feedback intervention for children with persistent asthma and with frequent emergency department (ED) visits for asthma. The specific aim is to determine if providing the child’s primary care provider (PCP) and parent with asthma health information, including cotinine concentrations as a biomarker of second hand smoke exposure, is effective in reducing subsequent ED asthma visits. Overall 300 children have been recruited and are currently being followed for 12 months. Salivary cotinine concentrations are collected at baseline and 12 months post randomization to determine if providing the parent with a child’s cotinine level will motivate the family to institute a total home smoking ban and reduce the child’s exposure to second hand smoke and reduce ED utilization.
