The need for hospitalization for right lower lung infection is determined by a comprehensive assessment by a clinician. Younger patients with better health, less underlying disease, no obvious contraindications to drug use, common bacterial infections, and mild disease are treated with oral antibiotics on an outpatient basis. Older patients, those with more underlying disease, and those with more extensive lesions are recommended to be hospitalized for observation and treatment. The Chinese guidelines for the diagnosis and treatment of community-acquired pneumonia in adults recommend the use of the CURB-65 score as a criterion for determining whether a patient with community-acquired pneumonia requires hospitalization as follows: a score of 0-1 in principle for outpatient treatment, 2, recommending hospitalization or out-of-hospital treatment under strict follow-up, and 3-5 should be hospitalized. However, any scoring system should be combined with the patient’s age, underlying disease, socioeconomic status, gastrointestinal function and treatment compliance.
