title: The aging population poses a global challenge for blood services.
abstract: BACKGROUND
  The Finnish transfusion registry data suggest some alarming signals and future challenges that are likely to be faced by transfusion services as populations continue to age.
  
  
  METHODS
  Computerized data collection was performed on all potentially transfused patients in Finland, thus covering approximately 70% of all blood usage. We simulated the red blood cell (RBC) usage according to the Finnish practice on different age groups but the population demographics from other countries.
  
  
  RESULTS
  The Finnish data demonstrate a marked increase in RBC consumption with increasing age among recipients, beginning at around 50 years of age. The 70- to 80-year-olds have an eightfold higher RBC consumption than 20- to 40-year-olds.
  
  
  CONCLUSIONS
  A large part of the variation in RBC use per capita can be explained by the age distribution of the different populations and not by the different national and regional treatment policies and protocols used. If current efforts are not enough to serve the changing population demographic and if increasing demands for blood products cannot be met, there is need to consider unprecedented measures such as reversing certain donor deferrals or even exporting blood from country to country.
