Patterns of infections in older patients acutely admitted to medical wards: data from the REPOSI register

In older adults infections are among the leading causes of emergency department visits, hospitalization, morbidity and mortality [1–3]. Infections also occur as adverse events during hospitalization, as highlighted by the large use of antibiotics in this setting, resulting in an increase of hospitalization length and mortality rate [4–6]. There is a paucity of studies, especially in European countries, that did offer a general pattern on all the types of infections occurring in acutely hospitalized older patients, being the literature mainly focused on single type of infections (i.e. pneumonia and urinary tract infections). To fill this gap of knowledge, we chose to observe and describe the prevalence and types of infections in a large cohort of older hospitalized patients in the frame of REPOSI (REgistro POliterapie SIMI) register.
