Long-Term Survival After Aspiration Pneumonia in Older Inpatients: A Comparative Study

Area of Science:

• Geriatrics
• Pulmonology
• Epidemiology

Background:

• Aspiration pneumonia (AsP) is a major cause of mortality in the elderly but is understudied.
• Evaluating the short- and long-term prognosis of AsP in older hospitalized patients is crucial.

Purpose of the Study:

• To assess the short-term and long-term prognosis of aspiration pneumonia (AsP) in elderly inpatients.
• To compare outcomes of AsP with other pneumonias and general hospitalizations in the geriatric population.

Main Methods:

• Retrospective cohort study of patients aged 75 years and older admitted to an acute geriatric unit over one year.
• Comparison of clinical characteristics and 2-year survival between AsP, non-AsP, and other hospitalized patients.

Main Results:

• AsP patients (39/125) had higher 30-day (31%) and 2-year (69%) mortality rates compared to non-AsP (15%, 56%) and other patients (11%, 49%).
• Adjusted analysis confirmed AsP significantly associated with mortality (aHR 3.09 at 30 days, 1.67 at 2 years).
• No significant difference in long-term mortality was observed among survivors at 30 days across the three groups.

Conclusions:

• A third of hospitalized elderly patients with AsP die within 30 days.
• For AsP patients who survive the initial 30 days, long-term mortality risk is comparable to other hospitalized elderly patients.
• Optimizing early management strategies for AsP is essential to improve outcomes in this vulnerable population.
