The predictive value of ACD has not been evaluated in stable COPD patients in the community.METHODS AND RESULTS: We evaluated 488 patients (9.4%) with stable COPD under the care of a regional nurse-led community respiratory team between June 2008 - November 2010. 86% of patients were on inhaled beta agonists; 43% on long acting anti-muscarinics, 54% on inhaled steroids and 8% on oral steroids. Mean age of the patients was 73.9 ± 6.1 years, 43% were females and mean MRC grade was 2.2± 0.7. ACD was defined as hemoglobin (Hb) between 9-12g/dl. Mean Hb levels were 14.1± 0.7; 13.9 ± 0.3; 14.0 ± 0.6 and 13.7± 0.2 g/dL at 0, 6, 12 and 24 months. To rule out iron deficiency we sample serum ferritin. Mean serum ferritin levels in the entire study population were 242 ± 15.9 µg/L at the start and 227 ± 19.8 µg/L at the end. The prevalence of ACD was 13.9 ± 2 % (+95% CI) and 14.5 ± 1.3% respectively at the start and end of the study period. 2-year survival was 93% in the entire population; 81% in the anemic group (p<0.001). Risk-adjusted hazard ratio for 24 month mortality were 1.43 (1.19-1.98) for the anemic patients.CONCLUSIONS: ACD is relatively common in ambulatory COPD patients in the community and is associated with worse clinical outcomes. It is also a stronger independent predictor for mortality in the short term. ER -
