title: [Differences between public and private hospital care in Spain: the realities of health care or a numerical fallacy?].
abstract: OBJECTIVE
  To give an example of the misleading interpretations of the concepts "public and private" when dealing with simple data from hospital resources and activities in Spain.
  
  
  METHODS
  Data comes from the survey of hospitals (EESCRI) for the year 2002 in Catalonia. Using the figures corresponding to resources (number of centers and beds) and activities (discharges, stays, mean stay, occupancy, and rotation) comparisons are made among different variables (managing authority and funding source) reclassified, according to the concepts of public and private.
  
  
  RESULTS
  The figures on resources and activities offer a very different portrait about the public or private nature of the care provided, according to the variables being used for classification.
  
  
  CONCLUSIONS
  It is necessary to specify the concepts and variables to be used when analyzing the performance of health services and to improve the information sources in order to adapt them to the new management forms of the health services.
