Treatment of infections in elderly patients
1Office of Geriatrics and Extended Care, United States Department of Veterans Affairs, Washington, DC, USA.
Abstract:
Infections are common in elderly persons. The clinical manifestations of infection may be atypical or absent in the elderly. The microbial cause for many common infections may be more diverse in elderly patients, and obtaining diagnostic clinical specimens often is more difficult. Aging is associated with changes in pharmacokinetics and a higher rate of adverse drug reactions. These factors impact on the approach to treating infections in the elderly.
Insights
Infections present unique challenges in elderly individuals, often with atypical symptoms and diverse causes. Treatment requires careful consideration of age-related physiological changes and medication sensitivities.
Area of Science:
- Geriatrics
- Infectious Diseases
- Clinical Pharmacology
Background:
- Infections are highly prevalent in the elderly population.
- Clinical signs of infection can be subtle or absent in older adults.
- Diagnosing and treating infections in the elderly is complicated by physiological changes.
Purpose of the Study:
- To highlight the complexities of managing infections in elderly patients.
- To discuss the impact of aging on infection presentation and diagnosis.
- To inform the approach to antimicrobial therapy in geriatric populations.
Main Methods:
- Review of current literature on geriatric infections.
- Analysis of age-related changes affecting pharmacokinetics and pharmacodynamics.
- Discussion of diagnostic challenges and specimen collection in the elderly.
Main Results:
- Elderly patients exhibit atypical or absent infection symptoms.
- Microbial diversity in infections can be greater in older individuals.
- Diagnostic specimen collection is frequently more challenging in this demographic.
Conclusions:
- Aging significantly alters how infections manifest and are diagnosed in the elderly.
- Altered pharmacokinetics and increased adverse drug reactions necessitate tailored treatment strategies.
- Effective management of geriatric infections requires a multidisciplinary approach considering patient-specific factors.
