Pneumonia in older residents of long-term care facilities.
Compared with community-dwelling persons, residents in long-term care facilities have more functional disabilities and underlying medical illnesses and are at increased risk of acquiring infectious diseases. Pneumonia is the leading cause of morbidity and mortality in this group. Risk factors include unwitnessed aspiration, sedative medication, and comorbidity. Recognition may be delayed because, in this population, pneumonia often presents without fever, cough, or dyspnea. Accurate identification of the etiologic agent is hampered because most patients cannot produce a suitable sputum specimen. It is difficult to distinguish colonization from infection. Colonization by Staphylococcus aureus and gram-negative organisms can result from aspiration of oral or gastric contents, which could lead to pneumonia. Aspiration of gastric contents also can produce aspiration pneumonitis. This condition is not infectious initially and may resolve without antibiotics. Antibiotics for the treatment of pneumonia should cover Streptococcus pneumoniae, Haemophilus influenzae, gram-negative rods, and S. aureus. Acceptable choices include quinolones or an extended-spectrum beta-lactam plus a macrolide. Treatment should last 10 to 14 days. Pneumonia is associated with significant mortality for up to two years. Dementia is related independently to the death rate within the first week after pneumonia, regardless of treatment. Prevention strategies include vaccination against S. pneumoniae and influenza on admission to the care facility. This article focuses on recent recommendations for the recognition of respiratory symptoms and criteria for the designation of probable pneumonia, and provides a guide to hospitalization, antibiotic use, and prevention.
