How can families support COPD med adherence and mood after hospitalization?

[Elizabeth_R]

My father was recently hospitalized for a COPD exacerbation, and now that he's home, we're trying to establish a better daily management routine to prevent another crisis. He's on a combination inhaler and uses oxygen at night, but he struggles with remembering his medication schedule and gets discouraged by his limited mobility. For caregivers and patients, what practical systems or tools have you found most helpful for medication adherence, tracking symptoms, and maintaining a positive outlook while managing this progressive condition?
