The objective of this article is to identify risk factors, which are responsible for higher hospital resource use.
  
  
  METHODS

  RESULTS
  The main risk factors for higher hospital resource utilization were identified: longer length of stay in the hospital, type of operation, postoperative mortality, postoperative complications and age.
  
  
  CONCLUSIONS
  The main factors affecting higher hospital resource utilization are following: longer duration of stay in the hospital, advanced type of operation, postoperative mortality, postoperative complications and advanced age.
