Methods
To estimate the burden of disease of acute bronchiolitis (AB), we calculated the Disability Adjusted Life Years (7) (7) for AB using methods described by Murray and Lopez (8); which summed the years of potential life lost due to premature mortality and the years of productive life lost due to disability (YLD) (9). DALYs were calculated for the most important health outcomes of AB: AB, uncomplicated, AB with complications (hypoxemia, atelectasis, and pneumonia), AB with severe complications (PICO admission, pneumothoraxes, pleural effusions, sepsis) and AB with long term complications (recurrent wheezing). The study was approved by the Institutional Review Board of the University of Antioquia (2015-4690).
