title: Victims of cardiac arrest occurring outside the hospital: a source of transplantable kidneys.
abstract: BACKGROUND
  The use of non-heart-beating donors could help shorten the list of patients who are waiting for a kidney transplant. Several reports describe acceptable results of transplantations from non-heart-beating donors who had in-hospital cardiac arrest, but few reports describe results of transplantations from non-heart-beating donors who had cardiac arrest that occurred outside of the hospital (Maastricht type I and type II donors).
  
  
  OBJECTIVE
  To compare graft survival rates among patients receiving kidneys from heart-beating donors versus type I or type II non-heart-beating donors.
  
  
  METHODS
  Retrospective cohort study of transplantations performed from January 1989 to December 2004.
  
  
  METHODS
  Kidney transplant program of a teaching hospital in Madrid, Spain.
  
  
  METHODS
  320 patients who received a kidney transplant from non-heart-beating donors (273 type I donors and 47 type II donors) and 584 patients who received a kidney transplant from heart-beating donors divided into 2 groups according to donor age (age <60 years [n = 458] and age > or =60 years [n = 126]).
  
  
  METHODS
  The primary outcome measure was graft survival. The median follow-up time was 68 months (range, 9 to 198 months).
  
  
  RESULTS
  One- and 5-year graft survival rates were 90.7% and 85.5%, respectively, for transplants from heart-beating donors younger than 60 years of age; 79.8% and 73.3%, respectively, for transplants from heart-beating donors 60 years of age or older (P < 0.001); and 87.4% and 82.1%, respectively, for transplants from non-heart-beating donors (P = 0.22 [vs. those from heart-beating donors < 60 years of age] and P = 0.014 [vs. those from heart-beating donors >or = 60 years of age]). Graft survival did not differ between patients who received kidneys from heart-beating donors younger than 60 years of age and patients who received kidneys from non-heart-beating donors.
  
  
  CONCLUSIONS
  This single-site, observational study was retrospective, and immunosuppressive therapy regimens given to transplant recipients varied over time.
  
  
  CONCLUSIONS
  Outcomes of transplants from non-heart-beating donors and younger heart-beating donors are similar, and results for transplants from non-heart-beating donors improved compared with those from older heart-beating donors. On the basis of these results, the authors encourage other transplant units to adopt the use of type I and type II non-heart-beating donors.
