title: [Non safety costs in the Spanish health care system].
abstract: BACKGROUND
  In the context of budgetary difficulties, the estimation of non safety costs is an additional tool that may be useful in the decision making process of the health system as well as to improve the health care management. Until now there is no study that has estimated the costs of non safety in Spain in an integral way. The objective of this article is to show a first approach to the calculation of the costs of non safety referred to the year 2011.
  
  
  METHODS
  The study updated from the year 2005 an estimation of the costs of non safety affecting inpatients. Those costs referred to medication errors, to nosocomial infections and to surgical complications. The costs derived from the non safety related to outpatients are estimated from data obtained from the National Health Survey combined with other information of medication errors and their treatment costs that other authors calculated.
  
  
  RESULTS
  Non safety costs were 2,474 million euros and 960 million euros for hospitalized and non hospitalized patients respectively.
  
  
  CONCLUSIONS
  This first estimation shows that non safety costs are about 6% of total public health expenditure.
