However, uncontrolled asthma is common and often associated with low adherence to prescribed treatment.Aim: To study pharmacological treatment adherence in a population-based adult asthma cohort.Methods: In 2012-2014, n=1425 adults from a population-based asthma cohort in northern Sweden were invited to a follow-up including spirometry and a structured interview. N=1006 participated and n=573 had used asthma treatment during the last 12 months and were further studied (59% women, 32-92yr). Asthma treatment was classified by GINA treatment steps.Results: 67% used treatment in line with GINA treatment steps 1-3 and 33% within steps 4-5. 65% always took the treatment as prescribed, 53% never forgot the treatment, 59% never changed the dose, 65% never paused the treatment, 65% never took less, and 66% never took more than prescribed. A higher proportion of women than men never forgot (59% vs. 43%, p<0.001), never paused (69% vs. 60%, p=0.030) and never used more treatment than prescribed (70% vs. 61%, p=0.030). Reasons for not taking the treatment as prescribed were: 42% forgetfulness, 16% lack of willingness, 6% fear of side-effects, 5% too costly and 5% lack of treatment effect.Conclusions: In this adult asthma cohort, three out of five had high adherence, although men seem to have poorer adherence than women. Healthcare professionals still need to monitor adherence and reasons for non-adherence among patients with asthma.FootnotesCite this article as: European Respiratory Journal 2020; 56: Suppl. 64, 5169.This abstract was presented at the 2020 ERS International Congress, in session “Respiratory viruses in the "pre COVID-19" era”.This is an ERS International Congress abstract.
