Study title acronym
Study typeObservational study
Brief description of the studyAsthma is a common long-term condition which is responsible for considerable morbidity, mortality and costs. There are several related conditions, involving type 2 inflammation which have been identified as affecting asthma outcomes. The nine T2 co-morbidities of interest are: eczema, allergic rhinitis, chronic rhinosinusitis, nasal polyps, urticaria, allergic conjunctivitis, food allergy, eosinophilic oesophagitis and anaphylaxis. Because of the common underlying disease process, it has been suggested that successful treatment of one might also improve related conditions.
The frequency with which these conditions co-occur in patients with asthma has not yet been described, nor has the relationship between co-morbidity patterns with asthma severity and asthma-related resource utilisation.
The aim of this study is to describe the frequency and interrelations of these conditions, and assess associations with asthma severity, asthma-related healthcare resource utilisation and costs, within a real-world asthma population.
The prevalence of each co-morbidities pattern will be measured, and associations between co-morbidities described using likelihood ratios and principal component analysis. This will be used to select a subset of patterns, in which patient characteristics, asthma severity, healthcare resource utilisation and cost will be compared using multivariable regression models, in all patients and stratified by asthma severity, co-morbidity severity and activity, blood eosinophil count and age.

Disease epidemiology
Primary scope : Disease epidemiology
12. Main objective(s)
What is the main objective of the study?
To estimate the frequency of each combination of T2 co-morbidities in a real world active asthma population, and to select a limited set of common co-morbidity patterns for further investigation.
To describe the overlap between these patterns and between individual co-morbidities within the patterns in terms of patient demography, and asthma severity, resource utilisation and costs.
Are there primary outcomes?No
Are there secondary outcomes?No
13. Study design
What is the design of the study?
Cross-sectional study
Cohort study
14. Follow-up of patients
Will patients be followed up?Not applicable/no follow-up
15. Data analysis plan
Please provide a brief summary of the analysis method
Co-occurrence patterns of the co-morbidities will be visualised in frequency tables, and associations between co-morbidities measured using likelihood ratios. Associations of patterns with patient characteristics and health care resource utilisation and costs will be done using multivariable regression. Principal components analysis will be used to identify clustering of inter-related co-morbidities.
