Respiratory datasets
COPD and asthma datasets
Respiratory trials enrol tightly selected patients; most people with COPD or asthma would not qualify. Real-world data shows how treatments perform in practice — across exacerbations, healthcare use and comorbidity. BCONZ provides governed, de-identified US EHR datasets for COPD and asthma.
Not a free download. These are governed, research-grade datasets licensed for a defined purpose after a feasibility review — built for studies and products that public datasets cannot support.
Research uses
What respiratory datasets are used for
Comparative effectiveness
Real-world outcomes of inhaled therapies and biologics in routine COPD and asthma care.
Exacerbations and healthcare use
Emergency visits, hospitalisation and oral corticosteroid use over time.
Trial generalisability
How trial-eligible patients compare with the wider COPD and asthma populations.
Asthma–COPD overlap and phenotypes
Identifying and following severe, uncontrolled or overlapping disease.
How access works
- Tell us your research question through the research data request form.
- We confirm feasibility: whether a suitable cohort exists, its size, follow-up and available data types.
- Governance review and a data use agreement define the permitted purpose.
- The de-identified dataset is prepared, quality-reviewed and delivered securely.

Frequently asked questions
Respiratory datasets: common questions
What are the COPD and asthma patient numbers based on?
Figures are approximate and rounded down. They count patients in de-identified US EMR/EHR data with a recorded diagnosis in the area; a patient can appear in more than one indication. The cohort for a specific study is confirmed during feasibility.
How are these COPD and asthma datasets different from public datasets on Kaggle or GitHub?
Public datasets are valuable for learning and benchmarking, but they are usually small, single-source, fixed snapshots with limited clinical context and no route to more data. BCONZ datasets are research-grade, de-identified and licensed through governed partnerships, with longitudinal records and a feasibility step to confirm the cohort fits your study before any agreement.
Is this a free dataset download?
No. Access is licensed for a defined research or development purpose under a data use agreement, after a feasibility review. Tell us what you need through the research data request form.
Where does the data come from?
From US healthcare data partners, and from partner networks in other regions where a study needs them. Data is de-identified before research use and stays governed by the partner's agreement.
