Brief Summary:

Objectives: To estimate the rate of appropriate hospital admissions , and of discharge to home episodes that would have been appropriate admissions to the hospital, on patients with exacerbations of their COPD by using appropriateness explicit criteria developed with the RAND appropriateness methodology. To evaluate the validity of those criteria by looking at their correlation with morbid-mortality, use of medications and health resources. To identify the variability in the appropriateness admission/discharge among the different centres participating on the study.

Methodology: Prospective observational cohort study. 1. The investigators will apply the previously developed explicit criteria to a sample of COPD exacerbations presented in each of the Emergency Department of each participating hospital (16 centres). 2. The investigators will evaluate if there is variability among centres by comparing their appropriateness rates. 3. To study the validity of the criteria, on those admitted the investigators will collect information on their evolution (length of stay, need of medication, quality of life), complications, vital status during their admission until discharge, and up to 2 months after the visit to the Emergency Department the vital status, complications, readmissions and quality of life. On those discharged to home from the Emergency Department, the investigators will check the presence of complications, vital status, readmissions and quality of life. People trained will collect all the needed information, in the Emergency Department, during their admission, or by personal interview to all discharged to home and to all at 2 months after the visit to the Emergency Department.

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients with an exacerbation of chronic obstructive pulmonary disease attending the emergency departments (ED) of 16 hospitals in Spain

Inclusion Criteria:

  • Patients were eligible for the study if they presented to the Emergency Department with symptoms consistent of an exacerbation COPD. COPD was confirmed if the patient had a forced expiratory volume in 1 second/forced vital capacity (FEV1/FVC) quotient <70%. When COPD was newly diagnosed during the Emergency Department visit, to be included in the study a patient had to have COPD confirmed by spirometry within 60 days of the index episode at a time when he or she was stable.

Exclusion Criteria:

  • Patients were excluded from the study if, at the time they were seen in the Emergency Department , the exacerbation COPD was complicated by a comorbidity such as pneumonia, pneumothorax, pulmonary embolism, lung cancer, or left cardiac failure. Patients who did not wish to participate were also excluded.
