Item	Scoring
Weight	Score 1 if weight gain ≥1 kg in one dayScore 2 if weight gain ≥2 kg in three days
SpO2	Score 1 if <92%Score 2 if <90%
Temperature	Score 1 if ≥37.5 °CScore 2 if ≥38 °C
Heart rate	Score 1 if >100 beats/minScore 2 if >120 beats/min
Blood pressure	Score 1 if systolic pressure >160 or <100 mmHgScore 2 if systolic pressure >180 or <90 mmHg
Breathlessness	Score 1 if daily increase in mMRC Dyspnea Scale of 1 gradeScore 2 if daily increase in mMRC Dyspnea Scale of ≥2 grade
Sputum quantity	Score 1 if increase in frequency of expectoration of ≥50%
Sputum character	Score 1 if purulent
Algorithm	If the sum of the scores is ≥2, an alert will be issued.
