Study title acronymVALNAC09348
Study typeOther: Survey
Brief description of the studyThis survey aims to measure the awareness, knowledge and behaviour of prescribing physicians, gynaecologists and pharmacists with respect to the new (2018) RMMs for valproate, as well as of patients treated with valproate in France, Germany, Poland, Sweden, Spain and UK. The new RMMs include new prescribing and dispensing conditions, Pregnancy Prevention Program (PPP), educational materials (EM) i.e. Healthcare Professionals (HCPs) guide, Patient Card, Patient Guide, and Annual Risk Acknowledgement form.
Objectives for HCPs
- To assess HCPs awareness related to both receipt and reading of the new (2018) RMMs including direct healthcare professional communication (DHPC) and educational materials (EMs) for valproate-containing medicines.
- To assess HCPs knowledge with respect to the new (2018) RMMs including measures of PPP, prescribing/dispensing conditions and risks associated with exposure to valproate-containing medicines during pregnancy.
- To assess HCPs behaviour with respect to the new (2018) RMMs regarding the measures of the PPP.
Objectives for Patients
- To assess the awareness of women of child bearing potential (WCBP) treated with valproate-containing medicines related to both receipt and reading of the new (2018) RMMs including the educational materials provided by the HCPs.
- To assess the knowledge of WCBP treated with valproate-containing medicines with regards to risks associated with use of valproate-containing medicines during pregnancy and measures to avoid exposed pregnancies.
- To assess the behaviour of WCBP treated with valproate-containing medicines with respect to the new (2018) RMMs including measures of the PPP.

15. Data analysis plan
Please provide a brief summary of the analysis method
All the analyses will be descriptive. Continuous variables will be described by their mean, standard deviation, and median, first quantile (Q1), third quantile (Q3), minimum and maximum. Categorical variables will be described as total number and relative percentage per category.
Analysis for the survey will be performed for patients and HCPs (prescribers, gynaecologists and pharmacists) separately for the endpoints described below, and will include the total number of patients and HCPs with valid responses to all relevant questions and the percentage of patients and HCPs with a positive response for the questions.
The statistical results of the included European countries will be presented overall and then at country level. The analysis of the Patients’ and HCPs’ surveys will then be broken down by subpopulation of interest, i.e. according to therapeutic indication (epilepsy / bipolar disorders).
