Utility of Bronchiectasis severity index (BSI) as prognostic tool in patients with post tubercular bronchiectasis: An experience from a tertiary care hospital in North India

摘要

Background: Bronchiectasis severity Index (BSI) score which predicts the severity of the disease along with future exacerbations and mortality rate has been well validated in European patients; however there is paucity of data evaluating its validity in Indian patients. The authors therefore decided to evaluate the utility of BSI to predict exacerbations and mortality rate in patients with post tubercular bronchiectasis presenting to our facility. Methods: The study was a retrospective observational study done in patients with bronchiectasis secondary to tuberculosis. These patients were followed up for 4 years. BSI was calculated from different variables and descriptive statistics along with regression analysis were used to evaluate utility of BSI.
