The causes and frequency of acute hospitalization of patients with dementia in a long-term care facility.

A retrospective study of 81 patients with dementia in a long-term care facility was conducted to determine the causes and frequency of acute hospitalization and the cause of death in the patients who succumbed during the acute hospital admission. Pneumonia and urinary tract infections were the most frequent causes of acute hospitalization; septicemia and respiratory failure were the most frequent causes of death. These results suggest that patients with dementia are prone to acquire life-threatening infections.
