A preliminary data entry analysis on a multicentric informative system for split liver transplantation in two adult...

In the context of the national research program "Innovative Strategies to Expand Cadaveric Donor Pool for Liver Transplantation" (SITF project), funded by the Italian Ministry of Health, an experimental and multicentric Web-based information system was developed to automate theoretical matching between a potential donor and two adult recipients for in situ split liver transplantation (SLT A/A). Data entry in the SITF database was performed in addition to activities formally required for patient and donor management by national legislation and guidelines. Data entry carried out within the SITF database from January 1, 2005 to August 8, 2005 was processed by stratifying original variables as donor- and patient-related. Only records required for donor-recipients matching had a mandatory data entry. The donor subset showed data entry procedures in 62 variables for 20 potential donors, whereas in the patient subset, we found 28 variables for 100 potential liver recipients. In the donor subset, 1004 records were filled, for a raw completeness of 77.08%. After adjustment for appropriateness, there were 935 remaining records with an adjusted completeness of 76.64% (P = .823). In the patient subset, 2653 records were filled, for a raw completeness of 98.69%. No difference in patient subset records was found after rechecking for appropriateness. A significant difference occurred for adjusted completeness between the donor versus the patient subsets (P < .0001). The results of this study suggested that only the presence of mandatory donor records may produce a consistent database suitable for SLT A/A.
