Purpose: Missing or wrong data in the medical information of a cornea donor may cause a decrease of the safety in the donation process and may lead to transmission of diseases. To find out the error in data transmission we do a data-flow quality control of the medical information in the cornea donation process.
Method: In a retrospective study we checked the information in the medical record of 100 consecutive cornea donors in the time period from 1998 to 1999 in the university hospital of Halle-Wittenberg. Personal data, declaration of death, diseases, pathologic reports were checked in the medical report and were compared to the information in the donor information from of the eye bank. The number of data-flow errors was calculated.
Results: Twelve medical records were not available. In 67 cases all data were complete congruent and in 16 cases the information was in a different order, but complete. Five cases showed indifferent or missing data, but no cornea was transplanted with a contraindication for cornea donation.
Conclusions: The data-flow quality control of the medical donor information shows that we have to calculate with 5,7% missing or wrong data. Although this is a low rate, the cornea donation process must be adapted to avoid this error. A quality assurance system in general should be implemented in eye banking to increase the safety of corneal transplantation.
