1. Study identification
EU PAS Register NumberEUPAS2561
Official titleUse of inhaled long acting beta2 adrenoceptor agonists and the risk for Acute Myocardial Infarction (AMI). A methodological comparison across data sources and epidemiological design
Study title acronym
Study typeObservational study
Brief description of the studyThe studies described in this protocol are all performed within the framework of PROTECT (Pharmacoepidemiological Research on Outcomes of Therapeutics by a European ConsorTium) Work Package 2 and Working Group 1. The primary aim of these studies is to develop, test and disseminate methodological standards for the design, conduct and analysis of Pharmacoepidemiological (PE) studies applicable to different safety issues and using different data sources. To achieve this, results from PE studies on 5 key Drug / adverse events (D-AEs) pairs performed in different databases will be evaluated. The Use of inhaled long acting beta2 adrenoceptor agonists associated with the risk of myocardial infarction is one of the key D-Ae pair of interest. Therefore, emphasis will be on the methodological aspects of the studies in this protocol and not on the clinical consequences of studying the association under investigation.

12. Main objective(s)
What is the main objective of the study?
To assess the association between the use of inhaled long acting beta2adrenoceptor agonists and the risk of acute myocardial infarction with different study designs across different primary care databases and to compare the results between databases, across designs to evaluate the impact of design/database/population differences on the outcome of the studied association.
Are there primary outcomes?No
Are there secondary outcomes?No
13. Study design
What is the design of the study?
Cohort study
Case-control study
Case-crossover
Descriptive study = description of exposure and/or outcome in the whole database during a defined period of time
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
Descriptives
Extensive descriptive studies will be performed to characterize and compare exposure and outcome in the databases.
Cohort study
Incidence density will be calculated as the number of AMI divided by person-time. Stratified relative risk will be graphically shown with the Ramlau-Hansen method. Time-dependent Cox-regression models will be used for confounding factor adjusted analysis. Hazard ratio's will be calculated for current use of LABA compared to the control group.
Nested case control
Conditional logistic regression analysis will be used to estimate the risk (OR) of AMI with current use of LABA compared to the control group. OR for AMI will be estimated by comparing inhaled LABA with the control group (No-LABA) using conditional regression analysis.
CCO
The Nonparametric Multiple Intervals Approach will be used. OR will be calculated with the use of conditional logistic regression, as described above
