Viruses are thought to cause about 50% of cases of pneumonia. Viral pneumonia is generally less severe than bacterial pneumonia but can act as a precursor to it. Preventing any pneumonia in older adults is preferable to treating it.

Identification of the early stages of pneumonia in older patients can prove difficult.

Traditional symptoms and signs, including fever, may be absent. Limited evidence suggests that many tests that are useful in younger patients do not help diagnose infections in older adults. The onset of pneumonia in elderly people can often be rapid, and the prognosis is poor in severe pneumonia: as many as one in five will die.

The older you are, the more prevalent severe pneumonia becomes.

Patients in nursing homes appear to fare even worse, as they often have several comorbidities and poor nutritional status and are often physically inactive.

[5] In-hospital mortality is significantly higher, even after adjusting for age and sex. Common causative organisms in elderly people admitted to hospital with pneumonia include Streptococcus pneumoniae and Mycoplasma pneumoniae . Less commonly, Haemophilus influenzae and Staphylococcus aureus may be responsible. aureus , Klebsiella pneumoniae , and Pseudomonas aeruginosa are common causative organisms.

In community acquired pneumonia, the causative agent is often not known. Older patients may have amoxicillin 875 mg clavulanic acid 125mg polymicrobial infections, which could be a factor in those who do not respond to initial antimicrobial treatment. Sputum cultures are often not reliable, as the microbial aetiology of severe pneumonia based on invasive diagnostic techniques often differs from the organisms found in the sputum.

Assessment of 12,945 US Medicare in-patients with pneumonia, aged over 65, showed that initial treatment with a second-generation cephalosporin plus a macrolide, or a non-antipseudomonal third-generation cephalosporin plus a macrolide, or a fluoroquinolone alone lowered 30-day mortality. And an analysis of 101 patients aged > 75 (mean and SD, 82 ± 5.5) admitted to an intensive care unit reported significantly higher mortality in those who received inadequate antimicrobial therapy (39% versus 4%; P = 0.007).

Viral infections increase pneumococcal adherence to the local epithelium, facilitating bacterial infection.

Adhesion of Streptococcus pneumoniae to epithelial cells, for example, is significantly enhanced by human coronavirus HCoV-NL63 infection. Coronavirus causes inflammatory clavulanic acid uses damage in the lungs, preventing clearance of bacteria. Most deaths in the influenza pandemics of 1918, 1957, and 1968 were caused by secondary bacterial infections. Concurrent bacterial pneumonia was highlighted as a particular problem in elderly people in the 2003 SARS outbreak.

Early use of antibiotics in older adults Non-response to initial antimicrobial therapy increases mortality, and so the initial selection of antimicrobials is critical.

According to NICE, to cover atypical and multiple pathogens in older patients with pneumonia and at risk of severe complications, the recommended choices of antibiotics in the community are: Amoxicillin with 500 mg 3 times a day (higher doses can be used – see BNF) for 5 days Clarithromycin (if atypical pathogens) 500 mg twice a day for 5 days. Alternative oral antibiotics for penicillin allergy, if

Please note there was an error with the prescribing strategy and this has been corrected as of 20th March – Please Check NICE guidance for all recommendations. ‘ Prescribe oral amoxicillin 500 mg three times a day for 5 days (higher doses can be used — see the BNF) and (if atypical pathogens suspected) oral clarithromycin 500 mg twice a day for 5 days, or oral erythromycin (in pregnancy) 500 mg four times a day for 5 days.

Alternatively, if there is a penicillin allergy, or amoxicillin is unsuitable (for example atypical pathogens are suspected) options are oral doxycycline 200 mg on the first day then 100 mg once a day for 4 days (total course of 5 days), or oral clarithromycin 500 mg twice a day for 5 days, or oral erythromycin (in pregnancy) 500 mg four times a day for 5 days.’ The intensity of pneumonia in the community can be assessed using the CRB65 score; each factor scores one point: confusion (abbreviated Mental Test score 8 or less, or new disorientation in person, place, or time); a raised respiratory rate (30 breaths per minute or more); a low blood pressure (diastolic 60 mmHg or less, or systolic less than 90 mmHg); age 65 years or over. Score 1 or 2: intermediate risk (1?10% mortality risk). Score 3 or 4: high risk (more than 10% mortality risk). NICE recommends that anyone with a score of 2 should be admitted to hospital.

NICE’s approach, however, doesn’t account for the high risk in very elderly people. The mortality rate from COVID-19 approaches 15% at age 80 (Figure 1).

Current NICE guidance requires starting antibiotic treatment as soon as possible after establishing a diagnosis of community-acquired pneumonia, and certainly within 4 hours.

This strategy is supported by the results of a US multicenter retrospective cohort study, a medical record review of 14,069 patients aged over 65 years and hospitalized with pneumonia.
