Editing Bronchiectasis (section)

==Prognosis==
Two clinical scales have been used to predict disease severity and outcomes in bronchiectasis; the Bronchiectasis Severity Index and the FACED scale. The FACED scale uses the [[spirometry|FEV-1]] (forced expiratory volume in 1 second), age of the affected person, presence of chronic infection, extent of disease (number of lung lobes involved) and dyspnea scale rating ([[MRC dyspnea scale]]) to predict clinical outcomes in bronchiectasis. The Bronchiectasis Severity Index uses the same criteria as the FACED scale in addition to including criteria related to number of hospital admissions, annual exacerbations, colonization with other organisms and BMI (body mass index) less than 18.5. A decreased FEV-1, increasing age, presence of chronic infection (especially [[pseudomonas aeruginosa|pseudomonas]]), a greater extent of lung involvement, high clinical dyspnea scale ratings, increased hospital admissions, a high number of annual exacerbations, and a BMI less than 18.5 lead to higher scores on both clinical scales and are associated with a poor prognosis in bronchiectasis; including increased mortality.<ref name="O'Donnell NEJM">{{cite journal |last1=O'Donnell |first1=Anne E. |title=Bronchiectasis — A Clinical Review |journal=New England Journal of Medicine |date=11 August 2022 |volume=387 |issue=6 |pages=533–545 |doi=10.1056/NEJMra2202819|pmid=35947710 |s2cid=251495311 }}</ref>
