*Values are median, except utility which is mean. Unit change is the difference in absolute values between follow-up and baseline. Improvements in health status are negative for HADS and CAT, and positive for utility scores.
†The percentage of patients who improved by an MCID, which is 1.5 for HADS-A and HADS-D,21 2 for CAT and 0.051 for the EQ-5D-5L.20
CAT, COPD Assessment Tool; EQ-5d-5L, Euro Quality of life instrument; HADS, Hospital Anxiety and Depression Scale; HAH, Hospital at Home; MCID, minimally clinically important difference; UC, usual care.
