Aims:
To determine the association between different comorbidities and other clinical conditions with mortality in patients with multiple diseases (PMD) suffering from chronic obstructive pulmonary disease (COPD).
Subjects And Methods:
Patients with COPD and PMD criteria were included in an observational, prospective and multicentrer study. Data on age, gender, Charlson index, Barthel index, Lawton-Brody index, Pfeiffer test, sociofamilial Gijon scale, education level, hospitalizations during the previous 3 and 12 months and survival at one year were collected. The relationship between the variables and mortality were established by means of a univariate analysis and logistic regression model.
Results:
A total of 688 PMD with COPD and mean age of 77.9 years were included. The mean score one the Charlson index was 3.99 (2.07). The most frequent comorbidities were heart failure (59%), diabetes (48%), myocardial infarction (29%), moderate kidney failure (22%), cerebrovascular disease (19%), hypertension (71%), anemia (62%), atrial fibrillation (34%), dyslipidemia (28%) and obesity (21%). A total of 26% of patients were dependent for activities of daily living, 47% needed a caregiver and 54% were at risk of having social problems. At one year, 258 patients (37%) had died. The Charlson index, dependency for activities of daily living and anemia were associated with mortality and hypertension and capacity for reading and writing were associated with survival.
Conclusions:
Comorbidity and discapacity are two prognostic factors in COPD patients.

Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
