de la Rosa Carrillo D, et al. - In this prospective, observational, multicenter study in adult bronchiectasis patients hospitalized due to exacerbation, researchers assessed mean hospitalization costs and issues related to higher costs. They calculated all expenses starting from the patients’ arrival at hospital to their discharge, including diagnostic tests, treatments, transferals, home hospitalization, admission to convalescence centers, and hospitals’ structural costs for each patient (each hospital’s tariff for emergencies and 70% of the price of a bed for each day in a hospital ward). They found that, relative to the cost per process calculated by the health authorities, the mean cost of a hospitalization due to bronchiectasis exacerbation attained from the individual data of each episode was higher. Data showed that P. aeruginosa-induced chronic bronchial infection, which resulted in a longer hospital stay and the use of home hospitalization, was identified to be the most determining factor of a higher cost.
