Table 3

Distribution of the revisit group based on A-DROP and CURB-65 scores.

Clinical factors	Number of patients, N = 29
A-DROP score
A: age (years) (male ≥70 and female ≥75)	18 (62.1)
D: dehydration (BUN ≥21 mg/dL)	9 (31.0)
R: respiratory failure (SaO2 ≤ 90% or PaO2 ≤ 60 mmHg)	6 (20.7)
O: orientation disruption (confusion)	2 (6.9)
P: low blood pressure (systolic blood pressure ≤90 mmHg)	0
CURB-65 score
C: confusion	2 (6.9)
B: blood urine nitrogen >20 mg/dL	10 (34.5)
R: respiratory rate ≥30 breaths per minute	14 (48.3)
B: systolic blood pressure <90 mm Hg or diastolic ≤60 mmHg	3 (10.3)
A: age ≥65 years	21 (72.4)

BUN, blood urea nitrogen. Data are expressed as N (%).
