[Integral approach to the acute exacerbation of chronic obstructive pulmonary disease]

Abstract

Chronic obstructive pulmonary disease is a set of clinical processes that have in common a chronic and progressive obstruction to airflow, with episodes of exacerbation. These exacerbations are more frequent and severe over time, deteriorating the lung function. The main cause of exacerbations is bacterial infection. There are multiple guidelines and documents that statement the management of this pathology. However, they focus primarily on the treatment during the stable phase. This document addresses the problem of acute exacerbation due to an infection from a multidisciplinary perspective, focusing on the integral approach to the process, and including etiology, microbiological studies, resistance to antimicrobials, risk stratification and initial empirical therapeutic management (antibiotic and concomitant). In addition, it includes an approach to more complex aspects such as the management of special populations (elderly and immunosuppressed) or therapeutic failure. Finally, more controversial topics such as prophylaxis of infection or palliative treatment are specifically discussed.
