UNASSIGNED: Background Current guidelines recommend initial treatment with anticoagulants at home in @entity1 with acute @entity1150 ( @entity1150 ) and in @entity1 with low-risk @entity1151 ( @entity1151 ) with adequate home circumstances. However, most of the @entity1 with @entity1211 ( @entity1211 ) are currently hospitalized regardless of their risk of short-term complications. Aim of the study To assess the proportion of outpatients with acute @entity1211 initially treated in hospitals, to assess the mean duration of hospitalization, and to identify predictors for in-hospital or home treatment. Methods Data of Italian @entity1 enrolled in the RIETE registry from January 2006 to December 2013 were included. Results Altogether 766 @entity1151 and 1,452 isolated @entity1150 were included. Among @entity1151 @entity1 , mean PESI score was 84 points (SD 35), and 56% of @entity1 had a low-risk PESI score (<85). In all, 53.7% of @entity1150 and 17.0% of @entity1151 were entirely treated at home, and 38.2% of @entity1150 @entity1 and 19.9% of @entity1151 @entity1 were hospitalized for    <=5 days. On multivariate analysis, low PESI score was not independently associated with the hospitalization of @entity1151 @entity1 . Conclusions One in every two @entity1 with @entity1150 and five in every six with @entity1151 are still hospitalized. Key Messages A significant number of @entity1 with @entity1211 ( @entity1211 ) are still hospitalized for the acute phase of the treatment despite current guidelines recommending initial treatment with anticoagulants at home in @entity1 with acute @entity1150 ( @entity1150 ) and in @entity1 with low-risk @entity1151 ( @entity1151 ) with adequate home circumstances.
