Symptoms, Causes, Treatment, and Prevention of Pneumonia in the Elderly
Pneumonia, an infection that inflames the alveoli in the lungs, can be a serious health concern for older adults. Symptoms such as cough and shortness of breath are common, and in some cases, the elderly may also experience weakness, lack of appetite, or changes in functional status.
In older adults, pneumonia can be caused by various germs, with Streptococcus pneumoniae, Haemophilus influenzae, and respiratory viruses being more frequently isolated from adults with CAP who are ages 65 years and older. Bacterial pneumonia is treated with antibiotics, the types of which depend on the type of bacteria causing the infection and its severity. They may be given orally or by IV.
Viral pneumonia, on the other hand, is treated with supportive care, such as easing symptoms, maintaining hydration, and monitoring vital signs. In some cases, antiviral drugs may be used.
It's important to note that older adults may not always show typical signs of a fever, and their body temperature might be lower than normal. Confusion or delirium, urinary incontinence, and a bluish color in nails, face, or lips are also signs that require immediate medical attention.
Rest is crucial for the body to respond to the infection, and overdoing activities should be avoided. However, trouble breathing, chest pain, or new confusion, delirium, or changes in functional status are signs that require a trip to the doctor.
Hospitalization is a common outcome for community-acquired pneumonia (CAP) in people ages 65 years and older. Older adults are more likely to have chronic health conditions such as COPD or heart disease, increasing their risk for pneumonia. Pneumonia in older adults also has an increased risk of hospitalization and mortality when compared to other age groups.
Diagnosis may require blood tests, imaging, cultures, pulse oximetry, and testing for COVID-19 and the flu. Fluids are important during pneumonia recovery, and adequate fluid intake can be maintained through oral consumption or IV fluids in a hospital setting.
Recovery may take longer in some cases, and older adults should pay close attention to their nutrition, fluid intake, rest, and managing underlying health conditions during the recovery period.
Prevention is key, and older adults can help protect themselves by getting the pneumococcal vaccine, getting the influenza vaccine each year, washing their hands regularly, avoiding smoking, making healthy lifestyle choices, and getting the pneumococcal vaccine if they have a weakened immune system or chronic lung, kidney, or heart conditions.
Older individuals with swallowing disorders can be at higher risk for aspiration pneumonia. Recurrence of pneumonia is possible, with one study finding that it occurred in 9% of participants over a period of 5 years. Recurrence was associated with reduced functional status.
Complications from pneumonia can include respiratory failure, fluid accumulation in and around the lungs, sepsis, lung abscess, and death. The most common complications of pneumonia in older adults include lung abscess, pleural effusion, pleuritis (inflammation of the pleura), aspiration pneumonia, toxic pulmonary edema (Mendelson syndrome), empyema, and acute respiratory distress syndrome (ARDS).
Oxygen therapy may be used for hospitalized older adults with pneumonia to ensure they are receiving enough oxygen. The immune system naturally weakens as we age, making pneumonia more severe in older adults.
In conclusion, pneumonia can be a serious health concern for older adults, but with proper treatment, diagnosis, and prevention measures, its impact can be minimized. It's important for older adults to take steps to protect themselves, such as getting vaccinated, practicing good hygiene, and managing their underlying health conditions. If you suspect you or a loved one has pneumonia, seek medical attention promptly.
