12 II) Main problems during validation period Approximately 40 initial mails have been sent for data clarification 81 queries (query = each single question sent to NFPs regarding data uploaded)

13 III) Common problems observed Quantitative information 46% of all queries are related to missing values, errors of calculation, not understandable data, wrong data reported and/or reported in the wrong place. Qualitative information 37 % of all queries are related to clarifications of provided data, abbreviation used unclear, term/definition unclear, references provided but unclear, methodological info provided but unclear. Other problems: Not available values missing Inconsistencies (discrepancies between years, between STs and NRs) Upload interface Most of those errors can be avoided

14 IV) Future developments Quality should include reducing surprises by highlighting realities in time to prepare for possibilities… Foster development of quality control and assurance at NFP level More systematised quality control (FONTE) Further consolidation of EMCDDA quality reports
