Study design details

• Main study objective:
  To determine the extent of awareness of the PPP and of the risk of teratogenic effects in women of childbearing potential and pregnant women exposed to oral retinoid containing medicinal products, by patients and by healthcare professionals.
• Data analysis plan:
  The surveys will generate descriptive statistics, describing the distribution of characteristics of patients and HCPs for the variables included in the querstionnaires. Univariate and bivariate analyses will be conducted according to stratifying variables, including HCP characteristics (age, gender, country, specialism, years of experience) and patient characteristics (age, diagnosis, past use of oral retinoids, type of prescriber, country). For the qualitative data, the analysis involves an inductive content analysis based on a close line-by-line reading of the responses and developing a conceptual coding scheme based on the major themes in the interview guides. Transcripts will be categorized individually by two coders in each country in native languages. Coders from all countries will meet prior to the analysis to predefine categories and codes to be used. They meet again to evaluate the categories identified and to write up the results using illustrative quotes.
