Identification and analysis of the data sources available in Spain for evaluating the criterion validity of the patient safety indicators proposed by the OECD in Spain’s National Health System


  • Identify the clinical databases which can eventually be used as a standard of comparison for each one of the PSIs.
  • Identify those PSIs for which there is no secondary data which can solely be studied by way of an ad hoc research study.
  • Assure the feasibility of using those indicators for which secondary data does exist (linking capacity of said databases with the hospital admission MBDS).
  • Plan record linking: contact owners, request permissions, assure record anonymity.
  • Design the research study making it possible to establish the criterion validity in those cases for which there are no existing secondary sources.
