Arm && Interventions

Group	Intervention	Description
COPD patients	Tiotropium bromide plus Olodaterol	COPD patients switching from Tiotropium monotherapy to dual therapy with Tiotropium bromide plus Olodaterol. All eligible Chronic Obstructive Pulmonary Disease (COPD) patients who had recently switched (within one week) from tiotropium monotherapy (Spiriva® Handihaler®) to dual therapy with tiotropium bromide plus olodaterol (Spiolto® Respimat®), in the Greek private and public sector pulmonary offices and clinics. The follow-up period was 3 months. Participants were visited at baseline (Visit 1) and at 3 months after baseline visit (Visit 2).

Primary Outcome Measures

Name	Time	Method
Change From Baseline in Patients' Quality of Life (QoL) According to the Total Score of COPD Assessment Test (CAT) at Month 3	At baseline and at 3 months after baseline.	The CAT is a patient-completed questionnaire assessing globally the impact of COPD on health status. It contains 8 items, where each item has a score range from 0 to 5. The CAT score is calculated by summing up the scores from the 8 items. CAT score ranges from 0 to 40. Higher score denotes a more severe impact of COPD on a patient's life. CAT score \<10 corresponding to mild impact on patients life is usually considered representing patients without impaired health status.

Secondary Outcome Measures

Name	Time	Method
Percentage of Patients With CAT≥10 at Baseline and Month 3	At baseline and at 3 months after baseline.	The CAT is a patient-completed questionnaire assessing globally the impact of COPD on health status. It contains 8 items, where each item has a score range from 0 to 5. The CAT score is calculated by summing up the scores from the 8 items. CAT score ranges from 0 to 40. Higher score denotes a more severe impact of COPD on a patient's life. CAT score \<10 corresponding to mild impact on patient's life is usually considered representing patients without impaired health status. CAT≥10 refers to impaired health status. The percentages of patients with CAT CAT≥10 at baseline and at Month 3 were reported below.
Change From Baseline in the Total European Quality of Life-Visual Analogue Scale (EQ-VAS) at Month 3	At baseline and at 3 months after baseline.	The EQ VAS records the patient's self-rated health on a vertical visual analogue scale. EQ-VAS score ranges from 0 to 100 where 0 represents the worst state the patient can imagine and 100 the best. Higher scores indicated better health state.
Percentage of Patients With Improved / Worsened Condition Mobility According to the European Quality of Life-5 Dimensions-5 Level (EQ-5D-5L) Questionnaire After 3 Months	At baseline and at 3 months after baseline.	EQ-5D-5L descriptive system comprises of 5 dimensions-mobility, self-care, usual activities, pain/discomfort \& anxiety/depression. Each dimension has 5 levels: not at all (level 1), mild (level 2), moderate (level 3), severe (level 4), extreme/leading to incapacity (level 5), with highest level corresponding to worst outcome. Subjects had to indicate their health state by choosing the appropriate level from each dimension. The dimension for mobility is reported in this endpoint.
Percentage of Patients With Improved / Worsen Condition in Self-care According to the European Quality of Life-5 Dimensions-5 Level (EQ-5D-5L) Questionnaire After 3 Months	At baseline and at 3 months after baseline.	EQ-5D-5L descriptive system comprises of 5 dimensions-mobility, self-care, usual activities, pain/discomfort \& anxiety/depression. Each dimension has 5 levels: not at all (level 1), mild (level 2), moderate (level 3), severe (level 4), extreme/leading to incapacity (level 5), with highest level corresponding to worst outcome. Subjects had to indicate their health state by choosing the appropriate level from each dimension. The dimension for self-care is reported in this endpoint.
Percentage of Patients With Improved / Worsen Condition Anxiety/Depression According to the European Quality of Life-5 Dimensions-5 Level (EQ-5D-5L) Questionnaire After 3 Months	At baseline and at 3 months after baseline.	EQ-5D-5L descriptive system comprises of 5 dimensions-mobility, self-care, usual activities, pain/discomfort \& anxiety/depression. Each dimension has 5 levels: not at all (level 1), mild (level 2), moderate (level 3), severe (level 4), extreme/leading to incapacity (level 5), with highest level corresponding to worst outcome. Subjects had to indicate their health state by choosing the appropriate level from each dimension. The dimension for anxiety/depression is reported in this endpoint.
Total Score in Abbreviated Patient Satisfaction and Preference Questionnaire (PASAPQ)	At 3 months after baseline.	Calculated from questions 1 to 13 in Part 1 of the PASAPQ. All questions in PASAPQ were answered on a 7-point scale ranging from 1= very dissatisfied to 7 = very satisfied. To calculate the total score, the sum of the 13 items of the two domains (performance and convenience) was transformed to a 0- (least) to 100- (most) point scale which is scaled positively: higher scores represent higher levels of satisfaction.
Overall Satisfaction of Inhaler	At 3 months after baseline.	Overall satisfaction according to Question 14 of PASAPQ (Part 1). Question 14 of PASAPQ has a score range from 1= very dissatisfied to 7 = very satisfied.
Percentage of Patients by Preference for Inhaler	At 3 months after baseline.	Percentage of patients by preference for inhaler according to Part 2 of the PASAPQ is reported.

Each dimension has 5 levels: not at all (level 1), mild (level 2), moderate (level 3), severe (level 4), extreme/leading to incapacity (level 5), with highest level corresponding to worst outcome. Subjects had to indicate their health state by choosing the appropriate level from each dimension. The dimension for pain/discomfort is reported in this endpoint.
Percentage of Patients With Adherence to the Medication	At 3 months after baseline.	Adherence is measured with the Simplified Medication Adherence Questionnaire (SMAQ), which is a short questionnaire including 6 questions, that assess patient adherence to the medication.
Willingness to Continue With Inhaler	At 3 months after baseline.	According to Part 2 of the PASAPQ; willingness to continue is self-reported by the patient by providing a single value between 1 and 100. 0 indicates that the patient is not willing to continue using the inhaler and 100 indicates that the patient is definitely willing to continue.
Change From Baseline of Patients' Dyspnea Status According to the Modified Medical Research Council (mMRC) Scale at Month 3	At baseline and at 3 months after baseline.	mMRC is a five-level rating scale ranging from 0 to 4 based on the patient's perception of dyspnea in daily activities. A higher score indicates a higher grade of breathlessness.
