title: Socioeconomic status does not affect the outcome of liver transplantation.
abstract: The outcome of liver transplantation is dependent on many factors. It was suggested that racial disparities in outcome may be related to differences in socioeconomic status (SES). In this retrospective study, we analyzed the effect of SES on graft and patient survival. Two hundred seventy-six adult patients who underwent liver transplantation at our institution from July 1988 to June 2001 were included in the analysis. Educational and occupation statuses were coded using established criteria (Hollingshead Index of Social Status [HI]). SES then was calculated using the HI formula: SES = education level x 3 + occupation x 5, and categorized into four groups: group 1, score less than 29 (n = 71); group 2, score of 29 to 42 (n = 82); group 3, score of 42 to 53 (n = 69); and group 4, score greater than 53 (n = 54). Kaplan-Meier analysis was used for graft and patient survival, and Cox regression analysis was used to determine the effect of confounding factors. Demographics of all four groups were similar. One-, 2-, and 5-year graft and patient survival did not differ significantly across groups by Kaplan-Meier and Cox regression survival analysis. In conclusion, SES did not predict graft and patient survival after liver transplantation.
