We describe the clinical and epidemiological characteristics of patients hospitalised with confirmed 2009 pandemic influenza A(H1N1) in Spain from April to December 2009 and the risk factors associated with a worse outcome (admission to an intensive care unit or death) in adults. Case-based epidemiological information was collected as part of the national strategy for the surveillance of severe cases. Of 3,025 patients, 852 were admitted to an intensive care unit and overall, 200 died. The median patient age was 38 years (range: 094). A total of 662 (26%) patients had no underlying risk conditions. Antiviral therapy was initiated within 48 hours after symptom onset in only 35.2% (n=711); the median length of time before treatment was four days. In a multivariate analysis, the start of antiviral therapy more than 48 hours after symptom onset (odds ratio (OR) 2.39; 95% confidence interval (CI): 1.79 to 3.2), morbid obesity (OR: 2.01; 95% CI 1.38 to 2.94), cardiovascular disease (OR: 1.79; 95% CI: 1.2 to 2.67) and chronic obstructive pulmonary disease (OR: 1.51; 95% CI: 1.03 to 2.2) were significantly associated with a worse outcome in adults.
