Social and clinical predictors associated with prolonged hospital stays for patients with severe exacerbation of chronic obstructive pulmonary disease.

To determine whether there are social factors that affect the prolonged hospital stay (PHS) of patients with severe chronic obstructive pulmonary disease exacerbation (COPDE), as well as clinical-demographic factors. We conducted a prospective cohort study that consecutively included patients who were admitted to a Pneumology department for COPDE. We recorded demographic, clinical (tobacco use, exacerbations and infections, dyspnoea, impact according to CAT questionnaire, pulmonary function, comorbidities, oxygen therapy and noninvasive ventilation) and social (financial status, caregiver availability and overload, dependence for basic and instrumental activities, social risk and use of social services) variables, employing questionnaires and indices such as Barthel, Lawton-Brody, Zarit, Barber and Gijón. We performed a univariate and multivariate analysis using a logistic regression model. The study included 253 patients, with a mean age of 68.9±9.8years; 77.1% of whom were men. The logistic regression model included active tobacco use, FEV Variables related to the social sphere play a relevant role in hospital stays, as do the impact of the disease and the persistent use of tobacco by patients with severe COPD exacerbation.
