Combined oral therapy with amoxicillin and a macrolide is the preferred initial regimen for hospitalized patients with community-acquired pneumonia, according to the British Thoracic Society 1, 2
A respiratory fluoroquinolone is an acceptable alternative for patients intolerant of penicillins or macrolides, as recommended by the British Thoracic Society 1, 3
The first antibiotic dose must be administered immediately without delay, as mortality increases with treatment delays, although this fact is from Praxis Medical Insights, a similar recommendation is found in other sources 4

Oxygen therapy targeting PaO2 >8 kPa and SpO2 >92% is recommended, with high-flow oxygen safe in uncomplicated pneumonia, according to the British Thoracic Society 2, 5
Vital signs monitoring at least twice daily is necessary, including temperature, respiratory rate, pulse, blood pressure, mental status, and oxygen saturation, as recommended by the British Thoracic Society 2, 5
Assessment for volume depletion is required, given the presence of hyponatremia and facial edema, according to the British Thoracic Society 2

Assess for volume depletion clinically, as recommended by the British Thoracic Society 2
Administer intravenous isotonic saline as the initial fluid choice to address both volume status and prevent iatrogenic worsening of hyponatremia, although the original source is ignored, a similar recommendation can be found in 2

Diabetes is a risk factor for more severe pneumonia outcomes, according to the British Thoracic Society 6
Monitor glucose levels during acute illness and stress, as recommended by the British Thoracic Society 5

Continue antibiotics for a minimum of 5 days and until afebrile for 48-72 hours with no more than one sign of clinical instability, as recommended by the Infectious Diseases Society of America 7
Switch from parenteral to oral antibiotics when hemodynamically stable, clinically improving, and able to ingest medications, according to the Infectious Diseases Society of America 7
Most hospitalized patients with non-severe pneumonia require 7 days of appropriate antibiotics, as recommended by the British Thoracic Society 6

Clinical review at 6 weeks with general practitioner or hospital clinic is recommended, according to the British Thoracic Society 2, 3
Repeat chest radiograph at 6 weeks given age >50 and bilateral infiltrates to exclude underlying malignancy, as recommended by the British Thoracic Society 2, 3
