Multivariable Analysis
Multivariable logistic regression using weighted outcomes data from table 3 was analyzed to calculate odds ratios for in-hospital mortality, complications, LOS, and total hospital charge for transplant recipients. These results are outlined in Table 4, with Non-Tx as the reference. As there was no mortality in PTx and KPTx, there was no multivariable comparison made. The risk of developing any complication was greatest in KPTx (OR 3.512, p<0.01), followed by PTx (OR 2.174, p<0.01), then KTx (1.674, p<0.01). In the adjusted outcomes, LOS and total hospital charge were not increased in transplant recipients. Table 5 shows the multivariate analysis in transplant centers. The risk of any complication was highest in KPTx (OR 4.302, p<0.01), followed by PTx (OR 2.413, p<0.01), then KTx (OR 1.362, p<0.01). Of note, KTx showed increased in-hospital mortality in transplant centers (OR 1.913, p<0.01), although the overall mortality rate was low in this cohort (3.9%).
The multivariate analysis was repeated for emergency CABG, as shown in Table 6. The risk of complication was highest among KPTx (OR 3.707, p<0.01), followed by KTx (OR 1.803, p<0.01). PTx was not associated with increased risk. Table 7 outlines the same multivariate analysis in transplant centers. Again, the risk of developing any complication was highest in KPTx (OR 10.072, p<0.001). KTx had increased in-hospital mortality (4.965, p<0.01) in transplant centers. In the adjusted outcomes, LOS and total hospital charge were not increased in transplant recipients.
