Factors associated with changes in quality of life of COPD patients: A prospective study in primary care

Although overall changes in HRQoL observed after one year were minimal, more than one third of patients improved significantly, and one third had significantly worse HRQoL. Clinical factors were independently associated with these changes, emphasizing the relevance to improved HRQoL of starting a healthy lifestyle and respiratory treatments and the negative impact on HRQoL of COPD symptoms onset and admissions.
