简要总结
This is a randomized, multi-centre, open-label, placebo-device, cross-over study, with a 2x2 complete block design in subjects with chronic obstructive pulmonary disease (COPD) to assess the benefits of delivering triple therapy using a single ELLIPTA dry powder inhaler (DPI) (closed triple therapy) versus delivering triple therapy using two different types of DPI (open triple therapy). The primary objective of the study is to evaluate the proportion of COPD subjects who make critical errors when using a single ELLIPTA DPI versus those using combinations of DISKUS® with HANDIHALER®, or TURBUHALER® with HANDIHALER. At Visit 1, all subjects will demonstrate the use of ELLIPTA DPI, and HANDIHALER DPI in combination with either DISKUS DPI (in sub-study 1) or TURBUHALER DPI (in sub-study 2), based on the treatment sequences. At the end Visit 1, subjects will complete the inhaler preference questionnaire (PQ). There is no active treatment and subjects will continue to take their own prescribed COPD medication for the duration of the study.

结局指标
主要结局
Percentage of Participants Making at Least One Critical Error After Reading the Patient Information Leaflets (PIL)
时间窗: Day 1
Participants were provided with the relevant section of the PIL, explaining correct use, for each DPI they were to be tested on. A critical error was defined as an error that was most likely to result in no, or a significantly reduced amount, of medication being inhaled by the participant. After reading the PIL for each DPI to be tested, participants demonstrated the DPI and critical errors made by the participants while using each DPI were recorded by the Healthcare Professional (HCP) on the checklists provided. Percentage of participants making at least one critical error after reading PIL were reported.
