Waitlist removals include patients listed prior to 2/27/02 but removed after this date. This data does not account for patients still on the waitlist as of 7/24/10. Data provided from each center and from UNOS data.
Percentage equals the proportion of all removals for that specific reason.
P<0.001 for chi-square test comparing the proportion removed for each reason, among all waitlist removals, across all 4 centers.
Excludes other removals and includes patients removed with the UNOS codes of transferred to another center, refused transplant, candidate condition improved, candidate listed in error, candidate removed in error
True removals for death or clinical deterioration equals patients coded as removed for death or clinical deterioration in UNOS database plus “other” patients who truly were removed for death or clinical deterioration
Misclassified patients are patients truly removed for death or clinical deterioration, but coded as “other” respectively The percentage is defined as: (number of removals for death or clinical deterioration coded as “other”)/(true number of removals for death or clinical deterioration). P<0.001 comparing the proportion of misclassified deaths per center
P<0.001 comparing the proportion of misclassified removals per center
