Brain death: epidemiology and quality control of solid organ donor generation

Successful solid organ transplant programs need effective organ procurement systems. Evaluating and maintaining the quality of an organ procurement system requires multilevel institutional coordination as well as reliable information regarding potential donors. The objective of this study was to analyze the potential to generate adult solid organ donors at a countrywide level as well as at individual hospital levels in Uruguay from 2000 to 2002. The analyzed factors included: encephalic deaths (brain deaths) officially registered by the National Bank of Organs and Tissues (BNOT), the distribution of these individuals among the intensive care units (ICUs) located at various hospitals, the number of Real Donors at each hospital, and the relation between the brain deaths and the number of ICU beds equipped with artificial respirators. The Uruguayan solid organ donation rate is relatively high among Latin American Countries, but low in relation to developed countries. The conversion of potential donors to actual donors is similar to that seen in developed countries. However, the registered incidence of brain deaths in relation to the number of ICU beds is surprisingly below the recognized standard figure. To approach the reasons for this difference, efficient quality control mechanisms are needed in the various ICUs as well as comprehensive medical case history reviews of all patient records.
