Prevalence, Associated Factors Points and Implementation of Care Procedures of Chronic Obstructive Pulmonary Disease Exacerbation in Healthcare Institution

Study Overview
=================
Brief Summary
-----------------
Chronic Obstructive Pulmonary Disease (COPD) is a public health problem responsible for high mortality rate and significant costs for society. The disease evolution is punctuated by exacerbations worsening the health state of patients. Many guidelines of care procedures have been written but many disparities persist in medical practices. This pilot prospective observational study is an overview of current local practices in the university health center of Grenoble Alpes and it is the first step towards developing a regional observatory in order to standardize and improve patient cares. The primary outcome is to compare the international guidelines to the local practices regarding the prescription of key treatments of exacerbation, especially antibiotics.
