Patient-Reported Outcome In Two Chronic Diseases: A Comparison Of Quality Of Life And Response Profiles In Severe Migraine And Severe Asthma

Introduction: Migraine and asthma are two frequent, disabling, chronic disorders with a major impact on patient well-being. The objectives of this study were to compare subjective well-being between patients with severe forms of migraine or asthma using a panel of PROs.Methods: Adult patients were recruited during routine consultations with chest physicians or neurologists. Patients with severe migraine (reporting headaches on >= 8 days/month and having failed >= 2 prophylactic treatments) and patients with severe asthma (according to the 2017 GINA definition: requiring Step 4 or 5 treatment or presenting uncontrolled symptoms) were eligible. Each patient completed the EuroQol Questionnaire (EQ-5D-5L), the Work Productivity and Activity Impairment Questionnaire (WPAI) and the Hospital Anxiety and Depression scale (HAD). Patients with severe migraine the 6-item Headache Impact Test (HIT-6) and those with severe asthma completed the Asthma Control Test (ACT).Results: 249 patients with severe migraine and 96 with severe asthma were enrolled. Mean EQ-5D-5L utility scores were significantly higher in the severe migraine group than in the severe asthma group (0.75 +/- 0.25 vs 0.68 +/- 0.26; p<0.01). Low EQ-5D-5L utility scores were associated with frequent (>= 15 headache days/month) or disabling (HIT-6 score >= 60) headaches and with poor asthma control. Patients with severe migraine more frequently presented a HAD depression score >= 11 (23.0% in severe migraine; 7.5% in severe asthma; p<0.01), whereas those with severe asthma more frequently reported problems with mobility, self-care and usual activities. Absenteeism (percent worktime missed) was similar in both groups (severe migraine: 9.0%+/- 19.1%; severe asthma: 13.8%+/- 22.9%) but work impairment was higher in the severe migraine group (44.3% vs 28.4%; p<0.01).Conclusion: Quality of life, work activity and psychological distress are all deteriorated in both severe migraine and severe asthma. Different aspects are affected in the two diseases: a greater impact on psychological aspects in severe migraine and a greater impact on physical aspects in severe asthma.
