1. Study identification
EU PAS Register NumberEUPAS18049
Official titleDrug utilisation study, in five European countries, using cross sectional analysis, to assess the extent of prescriptions of trimetazidine for its withdrawn ophthalmological and ENT indications among general practitioners, ophthalmologists and ENT specialists
Study title acronym
Study typeObservational study
Brief description of the studyThe aim of the study was to verify the compliance of prescribers regarding the restricted indication of trimetazidine after marketing authorisation changes in 2012. The primary objective was to assess, per country, the proportion of prescriptions of trimetazidine for ophthalmological or ENT diagnoses (within the scope of its past indications) among the total prescriptions of trimetazidine after the restriction of its indications.

Additional information
Since there was no evidence supporting the expected proportion of TMZ prescription for ophthalmological or ENT diagnoses after the restriction of TMZ indications, a p-value of 50% was considered (largest sample size). Given this assumption, and for a two-sided confidence interval of 95% (t=1.96) and an error margin (e) of 5%, the required sample size was estimated at 384 prescriptions per country.

11. Scope of the study
What is the scope of the study?
Drug utilisation study
Primary scope : Drug utilisation study
12. Main objective(s)
What is the main objective of the study?
Assess, per country, the proportion of prescriptions of TMZ for ophthalmological and/or ENT diagnoses (within the scope of its past indications) among the total prescriptions of TMZ after the restriction of its indications.
Are there primary outcomes?Yes
The primary end point was the proportion of TMZ prescriptions for ophthalmological and/or ENT diagnoses (within the scope of its past indications) among all TMZ prescriptions in the targeted prescribers of each country.
Are there secondary outcomes?Yes
Assess the extent of TMZ prescriptions: for ophthalmo or ENT diagnoses before and after the restriction of its indications by specialty (GPs, ophthalmo, ENT specialists); with regards to specialists’ characteristics; after the restriction of its indications by GPs in the cardiovascular indication and by GPs (FR, ES) for angina pectoris without other concomitant prescriptions for angina pectoris.

15. Data analysis plan
Please provide a brief summary of the analysis method
The statistical analysis was conducted using SAS® software Version 9.2 for Windows ™ (SAS Institute, North Carolina, USA).
Continuous variables were described by the number of valid cases, the number of missing values, mean, standard deviation, median, Q1, Q3 and range.
Categorical variables were described as the total number and relative percentage per category.
The number of missing data was indicated and missing data was not taken into account for the calculation of the percentages.
Confidence intervals of 95% were calculated for each item, when relevant.
The statistical unit was the prescription (for extractions from PI database) or the dispensed prescription (for extractions from NDI database). Calculations were performed on raw data.
Prescribers’ profile was described per country: age, gender and region.
Summaries were reported at country level and by period (Reference period and assessment period) categorized according to the speciality.
