Abstract
- Aspiration pneumonia (AP) is an infectious process causing high rates of mortality. The purpose of this study was: 1, to describe the incidence from 2003 to 2013 of AP hospitalizations; 2, to assess time trends in hospital outcomes variables, and; 3, to identify the factors independently associated with in-hospital mortality (IHM).A retrospective observational study using the Spanish National Hospital Database, with patients discharged between January 2003 and December 2013 was conducted. Inclusion criteria were: Subjects aged 75years or older whose medical diagnosis included AP events code according to the ICD-9-CM: 507.x in the primary diagnosis field. Patient variables, up to 14 discharge diagnoses per patient, and up to 20 procedures performed during the hospital stay (ICD-9-CM), Charlson Comorbidity Index, readmission, length of hospital stay (LOHS), and IHM were analyzed.We included 111,319 admissions (53.13% women). LOHS decreased in both sexes (P0.001) and was significantly higher in men (10.4±10.31 vs. 9.56±10.02days). Readmissions increased significantly in women during the study (13.94% in 2003 to 16.41% in 2013, P0.001). In both sex, IHM was significantly higher in94years old subjects (OR: 1.43, 95%CI 1.36-1.51) and in those with readmissions (OR: 1.20, 95%CI 1.15-1.23). For the entire population, time trend analyses showed a significant decrease in mortality from 2003 to 2013 (OR: 0.96, 95%CI 0.95-0.97).Patients with AP are older, male, and have more comorbidities than those without AP. Over time, LOHS and IHM decreased in both sexes, but readmissions increased significantly in women.
