Adherence, quality of life, and satisfaction with conventional fix combined therapy versus maintenance and reliever therapy in patients with asthma after inhaler training

Objective Treatment adherence, asthma control, inhaler satisfaction, and quality of life of patients with asthma were investigated to examine whether there were any differences between conventional fixed combined therapy and maintenance and reliever therapy after inhaler education. Methods Cross-sectional observational follow-up of 120 patients with asthma receiving third- and fourth-step treatment was completed at zero, three, and six months. Fifty-eight patients received long-acting beta-agonists or inhaler corticosteroids (ICS) as maintenance therapy and short-acting beta-agonists (SABA) as reliever therapy (CONV) with Diskus and Ellipta devices. Sixty-two patients received ICS/formoterol as maintenance and reliever therapy (MART) with metered-dose inhaler and Turbuhaler devices. The asthma control test (ACT), feeling of satisfaction with the inhaler (FSI-10) questionnaire, Morisky Green Levine (MGL) scale, and quality of life questionnaire (AQLQ) were evaluated at each visit. Results Significant improvement was observed in the ACT, AQLQ, FSI-10, MGL scales, and inhaler technique in both groups over time (p < 0.05). There was no difference in the MGL scale between the groups at all visits. Nonadherence was highest in the Diskus device group (55%) and lowest in the Ellipta device group at the first visit (25%). While 36% of the patients had low adherence at the first visit, this decreased to 12% by the last visit. A significant correlation was found between ACT and MGL at all visits (p < 0.001). Conclusion Asthma control, adherence, inhaler satisfaction, and quality of life improved equally with regular follow-up and standard inhaler education in the CONV and MART groups
