RATIONALE: Aspiration pneumonia is a subset of pneumonias prevalent in elderly patients and patients with neurologic disorders. Previous studies mostly reported incidence and/or mortality rates from regional data or in specific subgroups of patients. There is paucity of nationwide data in contemporary United States population.
OBJECTIVES: To describe United States national trends in acute care hospital admission for aspiration pneumonia from 2002 to 2012.
METHODS: We used the US Nationwide Inpatient Sample (NIS) database to identify patients admitted with a primary diagnosis of aspiration pneumonia between 2002 and 2012. We estimated trends in the incidence, in-hospital mortality, length of stay (LOS), and total hospitalization cost for patients admitted for aspiration pneumonia and stratified based on patient age (≥65 versus patients aged <65). Multivariable logistic regression analysis was used to identify independent predictors for in-hospital mortality.
RESULTS: A total of 406,798 patients (weighted: 1,741, 517) admitted for aspiration pneumonia were included in this study. There were 84,200 (20.7%) patients aged <65 and 322,598 patients (79.3%) aged≥65. From 2002-2012, the overall incidence of aspiration pneumonia decreased from 8.2 cases to 7.1 cases per 10,000 people and in-hospital mortality decreased from 18.6% to 9.8%. For patients age ≥65, the incidence decreased from 40.7 cases to 30.9 case per 10,000 people and the in-hospital mortality decreased from 20.7% to 11.3% . The median total hospitalization charge increased in both groups (age≥65:$16,173 to $30,280; age< 65: $17,517 to $30,526). In multivariable logistic analysis, patients aged≥65 or treated in a non-teaching hospital were independent predictors for in-hospital mortality.
CONCLUSIONS: The incidence and mortality of patients admitted to acute care hospitals for aspiration pneumonia decreased between 2002 and 2012 in the United States. This difference was more evident in for elderly patients. However, the cost of hospitalization has almost doubled. Age≥65 is an independent predictor for in-hospital mortality among patients admitted for aspiration pneumonia. Strategies to prevent aspiration pneumonia in the communities should be implemented in the aging US population.
