1. Study identification
EU PAS Register NumberEUPAS10684
Official titleComparative Effectiveness of Extra-Fine Particle Inhaled Corticosteroid (ICS) and Alternative Guideline-Recommended Step-Up Options in Pre-School Children
Study title acronym
Study typeObservational study
Brief description of the studyThis will be a prospectively planned matched cohort study drawing on retrospective, electronic medical records from the Optimum Patient Care Research Database (OPCRD). The small particle size of extra –fine ICS may be particularly relevant for younger, preschool (<5 years) children, in whom a greater proportion of airways are classified as small. The aim of this study is to test the hypothesis that use of EF ICS in pre-school children (i.e. ≤5 years of age) with asthma/wheeze will achieve better outcomes than treatment alternatives (i.e. NEF ICS, LTRA, or SABA) .

Effectiveness evaluation
Primary scope : Effectiveness evaluation
12. Main objective(s)
What is the main objective of the study?
The aim of this study is to test the hypothesis that use of extra-fine ICS in pre-school children (i.e. ≤5 years of age) with asthma/wheeze will achieve better outcomes than treatment alternatives (i.e. non extra-fine ICS, LTRA, or SABA).
Are there primary outcomes?Yes
Exacerbations (ATS/ERS definition) defined as occurrence of an:
• Asthma-related: Hospital admissions OR A&E attendance; OR
• An acute course of oral steroids (coded for asthma or wheeze).
Are there secondary outcomes?Yes
-Acute respiratory event
-Risk Domain Asthma Control
-Overall Asthma Control (OAC)
-Treatment stability
-SABA usage
-Controller-to-Reliever Ratio
-Oral Thrush
13. Study design
What is the design of the study?
Cohort study
Observational, matched cohort study drawing on retrospective, EMRs from the OPCRD
14. Follow-up of patients
Will patients be followed up?Yes
Please describe duration of follow up
For this study the comparative effectiveness evaluation of guideline-recommended treatment options in pre-school children (NEF ICS vs EF ICS and LTRA vs EF ICS) over a 1-year outcome period will be assessed.
An extension of the primary analysis over a 5-year outcome period will take place.
15. Data analysis plan
Please provide a brief summary of the analysis method
Statistically significant results will be defined as p<0.05 and trends as 0.05≤p<0.10.
Summary statistics will be presented as appropriate for each variable:
• Variables measured on the interval or ratio scale: n and % of non-missing data; mean (standard deviation) and median (inter-quartile range)
• Categorical variables: n (%) of non-missing data; n (%) per category
Treatment cohorts were compared at baseline using the Mann–Whitney test for continuous variables and the Chi-squared test for categorical variables.
Conditional logistic regression will be used to compare baseline characteristics between matched cohorts. Any variables that remained potentially different between matched cohorts at baseline (p<0.10) will be included as potential confounding factors in the outcome analysis.
Conditional logistic regression will be used to compare cohorts for binary outcomes; and a conditional Poisson regression model will be used to compare outcome exacerbation rates.
