Abstract: Background:Patients with Down syndrome (DS) often survive into adulthood. Relatively little information is currently available regarding hospitalization outcomes among mature, older adults with DS. Objective:To identify risk factors associated with hospital mortality rates and increased costs for hospitalized older adults with DS. Methods:Data on hospitalized older adults with DS (≥65 years) were identified from the Nationwide Inpatient Sample database (6) from 2002 through 2012. Multivariate analyses were performed to evaluate risk factors associated with hospital mortality and hospitalization cost in these patients. Results:A total of 2,134 older adults with DS were identified. A temporal increase over the 11-year period was observed in the number of older adults with DS who were hospitalized (trend p < 0.0001). However, the hospital mortality rate and post-hospital discharge to skilled nursing facilities have decreased during the same time period. Risk factors associated with increased hospital mortality included advanced age (70–79 years), female gender, admissions in the western United States, and presence of comorbid conditions (ischemic heart disease, Alzheimer’s disease, and cerebrovascular accident). The mean cost was $18,241 (SD $56,105) over the 11-year period. However, no significant temporal changes in costs were noted (trend p = 0.14). Conclusions:The number of hospitalized elderly Americans with DS has increased over the 11-year period. However, hospital mortality and discharge to skilled nursing facilities have decreased during the same time period. Several demographic and co-morbid factors are associated with increased mortality. No significant differences in temporal trends in costs were noted.
