Background and objective:  The initial assessment of the severity of community‐acquired pneumonia (CAP) is important for patient management. The Japanese Respiratory Society (JRS) has proposed a 6‐point scale (0–5) to assess the clinical severity of CAP. The A‐DROP scoring system assesses the following parameters: (i) Age (male ≥ 70 years, female ≥ 75 years); (ii) Dehydration (blood urea nitrogen (BUN) ≥ 210 mg/L); (iii) Respiratory failure (SaO2 ≤ 90% or PaO2 ≤ 60 mm Hg); (iv) Orientation disturbance (confusion); and (v) low blood Pressure (systolic blood pressure ≤ 90 mm Hg). A‐DROP is a modified version of CURB‐65 (confusion, BUN > 7 mmol/L (200 mg/L), respiratory rate ≥ 30/min, low blood pressure (diastolic ≤ 60 mm Hg or systolic
