Objective: The prevalence of comorbid anemia in patients with COPD ranges from 7.5% to 34%. The aim of this study is to determine if anemia is a risk factor for readmission in COPD patients. Methods: This study analyzed the hospital data of 289,077 adults with acute exacerbations of COPD admitted to the hospital at any public center in Spain, in 2006 and 2007. We calculated the prevalence of anemia and compared readmissions between COPD patients with and without anemia. Multiple regression analyses were carried out with the aim of determining the risk of readmission attributable to anemia, after the correction of possible confounding variables. Results: Of the patients with COPD, 9.8% (n = 26,899) had a diagnosis of anemia. Anemic patients were older, more likely to be female and had a greater comorbidity burden than non-anemic individuals. Multiple regression modeling revealed that multiple independent factors were associated with an increased risk of readmission in persons with COPD. Anemia was one of the greatest risks: anemic patients had a 25% higher risk of readmission than non-anemic patients (odds ratio [OR], 1.25; 95% confidence interval [CI] 1.21-1.29). Conclusion: Utilizing an administrative database the authors found that anemia correlates independently with readmission in COPD patients. Limitations: This is a retrospective cohort study and thus subject to multiple forms of bias. Although spirometric evidence of COPD was not available, our case identification methods have been previously validated and found to be accurate in recognizing COPD.
Mortality and complications in very old patients (90+) admitted to departments of internal medicine in Spain
(Elsevier, 2011-02) Barba, Raquel; Marco Martinez, Javier; Zapatero, Antonio; Plaza, Susana; Losa, Juan Emilio; Canora, Jesus; Perez, Alejandro; García de Casasola, Gonzalo
Summary: Patients over 90 years of age (the "very elderly") account for an increasing number of admissions to departments of internal medicine (IM). The aim of this study was to analyse the demographic data, hospitalization characteristics, medical complications, and predictors of mortality in patients over 90 admitted to IM departments. Material and methods: All patients admitted to IM departments in Spain between the years 2005 and 2007 were analysed. Clinical and demographic data were compared with records from "younger elderly" patients (65-90). Results: During the study period, there were 1,567,659 patient admissions to IM departments in Spain, and 90,679 (5.8%) were older than 90. Hospital mortality occurred in 22.3% of very elderly patients. The main predictors for hospital death were pressure ulcer (Odds Ratio [OR] 1.55, CI95% 1.45-1.66), thromboembolic disease (OR 1.83, CI95% 1.61-2.09), nosocomial pneumonia (OR 2.53, CI95% 2.39-2.69), hip fracture (OR 2.20, CI95% 1.53-3.18), male gender (OR 1.06, CI95% 1.03-1.10), age (OR 1.05, CI95% 1.04-1.06), dementia (OR 1.13, CI95% 1.08-1.18), cancer (OR 1.60, CI95% 1.51-1.71), acute respiratory failure (OR 1.83, CI95% 1.76-1.89), acute infectious disease (OR 2.30, IC95% 2.11-2.52), and Charlson comorbidity index (OR 1.21, CI95% 1.16-1.26). Conclusions: Very elderly patients represent a large and growing fraction of the total admissions to IM departments in Spain. They are at higher risk for complications during their hospital stay and mortality rate is double that of the younger elderly.
