BACKGROUND: The widening gap between the numbers of patients on the waiting list for organ transplantation and the insufficient numbers of organ donors results in the use of “critical” donors, so-called marginal donors orextended criteria donors. Data concerning the evaluation of extended criteria donors (ECD) in Switzerland are sparse.

METHODS: All organ donors in Switzerland between 1.1.1998 and 30.6.2009 have been evaluated for special criteria. ECD were defined on the basis of at least one of seven criteria: six DOPKI criteria (ECD-DOPKI) and/or age ≥60 yr (ECD-Age). Once included in the study, special features, short time follow-up (first 7 days after transplantation) and the cold ischaemia time of all the transplanted organs were evaluated.

RESULTS: During the period 1.1.1998 to 30.6.2009, a total of 408 organ donors were classified as ECD, reflecting 39% of all organ donors in this time period. Despite the fact that all organ donors in this study fulfilled at least one inclusion criterion, the number of recipients with satisfactory primary organ function was always higher than the respective numberwith a negative primary outcome within the first seven days after transplantation. A longer cold ischaemia time was associated with organs showing insufficient primary organ function compared to organs with satisfactory primary function. A relevant causal relationship cannot be investigated on the basis of our limited data. In addition, a longer observation period would be necessary to draw a more precise conclusion.

CONCLUSIONS: ECD as defined by DOPKI and/or age represent a high proportion of all organ donors in Switzerland but show a remarkably good outcome.
