Regular use of inhaled corticosteroids can reduce the rate of hospital admissions for asthma by approximately one third, according to data published in Thorax. The researchers examined data from 2 population-based cohorts involving a total of 30,569 asthma patients ages 5 to 44 years between 1975 and 1991. Regular use of inhaled corticosteroids was linked to a 31% decrease in the rate of hospital admission for asthma and a 39% decrease in the rate of readmission.
Furthermore, the researchers estimated that regular use of inhaled cortico-steroids could prevent 5 hospital admissions and 27 readmissions per 1000 people per year.
