ABSTRACT
BACKGROUND: Evaluation of donation and transplantation activity allows for strategic planning. Liver donation and transplantation activity in the Metropolitan Area of the Valley of Mexico (MAVM) has never been published. The aim of this study was to analyze deceased liver donation and transplantation, liver use, and observed-to-expected (O:E) ratio in the MAVM. METHODS: Information from 2014 to 2018 was obtained from the National Center of Transplantation and adjusted per million persons. O:E ratio was analyzed and compared between regions. RESULTS: From all Mexican states, Mexico City (CDMX) had the highest liver donation and transplantation per million persons rates in the country. In contrast, when the MAVM was considered, the region was sixth in liver donation and first in transplantation, although the latter was not statistically different to Nuevo Leon (5.4 vs 4.3; P = .52). Liver use in Mexico State within the MAVM (37.8%) was not different from that of CDMX (15th in the nation, 35.2%, P = .78), while deceased donor liver use in the rest of the state was statistically higher (52.4%, P = .01; third in the nation). O:E ratio was higher in Mexico states outside the MAVM (CDMX 10.1, 2.1 vs 29.4, 26.5; P = .009). CONCLUSIONS: Analysis of deceased donation and transplantation of Mexican states without considering the metropolitan areas is insufficient. To consider CDMX as a region without acknowledging the MAVM leads to an inappropriately small denominator during efficiency analysis.
