Asthma is not controlled and a gain in ACT score equal to 3 points: | ||||
1 |
RED to RED
| Did not change the asthma control status—still not controlled. | 5–10 | 8–13 |
2 |
RED to YELLOW
| Did change the asthma control status—from not controlled to partially controlled. | 11–14 | 14–17 |
Asthma is partially controlled and a gain in ACT score equal to 3 points: | ||||
3 |
YELLOW to YELLOW
| Did not change the asthma control status—still partially controlled. | 15–16 | 18–19 |
Asthma moved from partially controlled to controlled and a gain in ACT score equal to 3 points: | ||||
4 |
YELLOW to GREEN
| Did change the asthma control status—from partially controlled to controlled. | 18–19 | 20–21 |
Asthma is controlled and a gain in ACT score equal to 3 points: | ||||
5 |
GREEN to GREEN
| Did not change the asthma control status—always controlled. | 20–21 | ≥23 |
Possible shifts: a series of shifts in care landscape were considered towards a target scenario where a patient with asthma experienced a clinically significant change in ACT score equal to the MID of 3 points in ACT score.
ACT, Asthma Control Test; MID, minimally important difference.
