Abstract To assess patient preferences for attributes of asthma treatments. Two hundred and ninety-eight patients, aged 18–60, from 15 centres in Sweden completed a questionnaire concerning their asthma and ranked 18 alternative treatments using conjoint analysis. Patients were treated with either inhaled corticosteroid (ICS) and short acting bronchodilator alone (42%) or ICS and long acting bronchodilator (58%). Attributes analysed were: maintenance treatment, additional reliever, time to onset and duration of reliever, number of symptom-free days (SFD) per month, and out-of-pocket cost per month. According to conjoint data the most important aspect of treatment was SFD. 40% of the patients had 15 or less SFD per month. 85% of the patients preferred another treatment than their current treatment, and the patients was prepared to pay approximately SEK 300 (€ 33) per month for the change. Treatment preferences were heterogeneous and in 78% not covered by current treatment guidelines. Overall, patients preferred a combination inhaler (50%) to separate inhalers, and a reliever that is both rapid- and long-acting (78%). Most preferred treatment was a combination inhaler for maintenance and reliever use (28%). Symptom-free days were most important. Patients favoured treatment with a combination inhaler and reliever therapy that was both rapid- and long-acting.
