title: [Assessment of websites with information on medicines].
abstract: OBJECTIVE
  To identify websites with information on medicines and assess, using experts, their adherence to codes of conduct and recommendations by the WHO.
  
  
  METHODS
  Cross-sectional study based on an ad hoc designed questionnaire (performed independently by 2 reviewers). The websites were identified by the Delphi technique (35 experts).
  
  
  METHODS
  Websites with information on medicines.
  
  
  METHODS
  A total of 35 websites selected by the Delphi technique. An acceptable level of stability was achieved in the third round (interquartile variability; <0.05).
  
  
  METHODS
  Responsibility, transparency and honesty, authorship of the information, content review policy, privacy and data protection policies, updated information and accessibility. A descriptive analysis of compliance was carried out and the kappa coefficient was estimated to evaluate the agreement between assessors (Fleiss's Criteria).
  
  
  RESULTS
  The National Prescribing Service Limited (NPS), PubMed, British Medical Journal, New England Journal of Medicine, Journal of American Medical Association, The Lancet, Fisterra and National Institute for Health and Clinical Excellence stood out with an overall high fulfilment of the questionnaire. The updated information dimension was the lowest evaluation for the different websites.
  
  
  CONCLUSIONS
  The quality of the web sites evaluated varied widely. Although there are several websites, which are detailed in the article, with high overall scores.
