To describe the characteristics of bacteraemias, according to age, in a community hospital.Material and methodA prospective study of bacteraemias was conducted in 2011. The patients were classified into 3 age groups: younger than 65 years, 65&ndash;79, and 80 or older. The study collected variables on the patients and episodes.ResultsThe study analyzed 233 bacteraemias in 227 patients (23.8% in those younger than 65 years; 38.3% in the 65&ndash;79 age group; and 37.9% in the 80 years or older group). The most common underlying disease in all the groups was diabetes mellitus. In the most elderly patients, the Charlson index was highest, there were a lower proportion of exogenous factors, and almost 25% were severely dependent (Barthel index <20). Escherichia coli was the most common germ, and the main focus was urological. The patients aged 80 years or older had predominantly healthcare-associated infections, less severe symptoms (sepsis) (66.3%) and higher mortality (29.1%) compared with the younger patients.ConclusionsThe very elderly patients with bacteraemia presented fewer exogenous factors, greater comorbidity and a poorer functional situation. The most common focus was urological and the origin was healthcare related. Despite their less severe clinical presentation, these patients&rsquo; mortality was greater, and their degree of dependence was a highly relevant independent risk factor.
