Environmental Intervention; The World Health Organization estimates that at least 300 million people suffer from asthma worldwide. Older adults ages 65 and over with asthma are the fastest growing age-group in the U.S. Studies in the United States show that asthma and other reactive airway diseases are under-diagnose among the elderly, that asthma relate morbidity and mortality among the elderly is increasing and that nationally the number of older adults dying from asthma is 14 times higher compare to those 18-35 years of age.
Data indicate that asthma relate morbidity and mortality; among the elderly are increasing and that the asthma relate mortality rate among older Americans; with asthma is 14 times higher when compare with cohorts aged 18-35. “Older adults also have greater risk of asthma relate respiratory impacts, since they spend up to 90% of their time in the home; so where many allergens and respiratory irritants are found,” explains David A. Turcotte, ScD.
“Although there is sufficient evidence that home interventions; which are effective in improving health of asthmatic children; so the Task Force on Community Preventive Services has state that there is insufficient evidence for the effectiveness of home interventions on asthmatic adults.”
For a study publish in Annals of Allergy, Asthma & Immunology, Turcotte and colleagues evaluate the hypothesis that multifaceted home; so environmental intervention improve the respiratory health; also reduce asthma triggers for older adults with asthma. Community health worker (CHW)-led interventions; which were conduct in the homes of low-income adults age 62 or older who were diagnose with asthma; also residing in public and private subsidize housing, from 2014 to 2017.
The respiratory health
Health and environmental assessment at baseline and follow-up 1 year later include collecting data on respiratory health, quality of life, medication use, doctor/emergency room/hospital visits, using the St. George Respiratory Questionnaire and Asthma Control Test and evaluation of asthma trigger activities and exposures through questionnaires and home surveys.
“Interventions include education on asthma and environmental triggers of asthma; environmental remediation including mattress/pillow covers, provision of vacuum with HEPA filters and green cleaning supplies, and some changes in home as needed: commercial cleaning, integrate pest management, gas stove replacement, mold remediation, installation/repair of exhaust fans,” says Turcotte.
Following the interventions, the study team find statistically significant reductions; so in self-report environmental asthma triggers and health improvements in doctor visits; which use of antibiotics for chest problems, respiratory symptoms, quality-of-life indicators, and asthma control. “This study suggests that a relatively low-cost, multifaceted environmental intervention in the homes of older adults with asthma can significantly reduce doctor visits and improve asthma control and overall health,” says Turcotte.
“They are like to see physicians incorporate home visiting with CHWs into the care of this patient population.” Our results provide evidence that multifaceted home interventions are effective in improving the environmental quality and respiratory health of an older adult population with asthma.
