Inclusion Criteria:
- Subjects of both sexes aged >=40 years.
- Subjects with a COPD diagnosis confirmed with a post-bronchodilator Forced Expiratory Volume in 1 second/Forced Vital capacity <70% recorded at any time in the medical record.
- Subjects with a history of smoking (current or past) >=10 pack-years.
- Subjects who have a qualifying peripheral blood eosinophil test recorded in the 3 months prior to the inclusion visit. If the subject has several eosinophil test recorded in this period, the one closest to the inclusion visit determined in the stable phase should be selected; if it is not available, the record closest to the inclusion visit will be selected, even if it has been determined during an exacerbation. If no records are available, the subject will be invited to perform the test at the inclusion visit.
- Subjects currently exposed to inhaled triple maintenance therapy, defined as at least one overlapping prescription of an ICS with a LABA and with a LAMA in 2 or 3 inhaler devices, without more than 30 days of separation between prescriptions.
- Subjects who have experienced >=2 moderate exacerbations or >=1 severe exacerbation in the 12 months prior to the inclusion visit. Moderate exacerbation is defined as an exacerbation requiring antibiotics and/or oral corticosteroids or requiring an emergency visit <24 hours (without hospitalization). Severe exacerbation is defined as an exacerbation requiring hospitalization.
- Subjects who consent to participate in the study by signing the subjects written informed consent form.
Exclusion Criteria:
- Subjects without a qualifying peripheral blood eosinophil test recorded in the 3 months prior to the inclusion visit and who refuse to perform the test during the inclusion visit.
- Subjects treated with oral corticosteroids continuously during the 12 months prior to the inclusion visit.
- Subjects with a diagnosis of Churg-Strauss disease, hypereosinophilic syndrome, allergic bronchopulmonary aspergillosis or other conditions that result in increased eosinophil levels independently of COPD.
- Subjects with oncologic disease undergoing treatment or with advanced oncologic disease (without possibility of remission), terminal subjects and/or subjects receiving palliative care.
- Cognitively impaired subjects who are not able to understand or complete the informed consent and HRQoL questionnaires.
- Subjects who have participated in an interventional clinical trial during the 12 months prior to the inclusion visit.

Subjects with COPD
Subjects with a COPD diagnosis confirmed with a post-bronchodilator Forced Expiratory Volume in 1 second/Forced Vital capacity <70% recorded at any time in the medical record who have a qualifying peripheral blood eosinophil test recorded in the 3 months prior to the inclusion visit attend to a routine follow-up visit during the inclusion period, fulfill the inclusion/exclusion criteria and provide informed consent to participate, will be included in this study.

Subjects age as a measure of sociodemographic characteristics
Временное ограничение: 4 months (inclusion period)
|
Age will be recorded for descriptive analysis of the sociodemographic characteristics of the subjects participating in the study.
A threshold of >=150 cells/microliter will be considered to determine a high level of eosinophil's, so only subjects meeting this criterion will be included in the analysis.

Number of subjects with different gender
Временное ограничение: 4 months (inclusion period)
|
Gender will be recorded for descriptive analysis of the sociodemographic characteristics of the subjects participating in the study.
A threshold of >=150 cells/microliter will be considered to determine a high level of eosinophil's, so only subjects meeting this criterion will be included in the analysis.

Number of subjects with different sociodemographic variables
Временное ограничение: 4 months (inclusion period)
|
Subjects with different educational level, employment status, monthly net income will be recorded for descriptive analysis of the sociodemographic characteristics of the subjects participating in the study A threshold of >=150 cells/microliter will be considered to determine a high level of eosinophil's, so only subjects meeting this criterion will be included in the analysis.

COPD Assessment Test (CAT) score as a measure of Health Related Quality of Life (HRQoL)
Временное ограничение: 4 months (inclusion period)
|
The CAT questionnaire is a COPD-specific questionnaire that measures the impact of the disease on HRQoL and allows symptoms to be described.
It consists of 8 items, which yield a score range from 0 to 40, 0 representing the lowest impact on HRQoL and 40 the maximum impact.

EuroQOL five dimensions five level (EQ-5D-5L) score as a measure of HRQoL
Временное ограничение: 4 months (inclusion period)
|
The EQ-5D-5L is a preference-based generic HRQoL questionnaire, consisting on five health dimensions (mobility, personal care, daily activities, pain/discomfort and anxiety/depression), divided in five levels of severity (no problems, slight problems, moderate problems, severe problems and extreme problems).
It included also a visual analogue scale (VAS) in which respondents are asked to evaluate their overall health status on a scale from 0 (worst imaginable health state) to 100 (best imaginable health state).
