Multivariable association of receipt of allograft nephrectomy with death from any cause in patients who had a failed kidney transplant and returned to dialysis

AnalysisAdjusted HR (95% CI) for Death for Nephrectomy versus Non-nephrectomy
Main
    original cohort (n = 10,951)0.68 (0.63 to 0.74)
    original cohort with adjustment for transplant center (n = 10,951)0.68 (0.63 to 0.74)
Sensitivity
    original cohort + patients whose transplants failed <90 d after initial transplant date (n = 13,702)0.67 (0.63 to 0.71)
    subset of original cohort who survived ≥30 d after transplant failure (n = 10,886)0.69 (0.66 to 0.74)
    original cohort + patients without documented Medicare fee-for-service coverage within 90 d after transplant failure (n = 14,352)0.67 (0.63 to 0.72)
    original cohort + patients with two transplants in which the transplant sequence was uncertain or unknown (n = 11,237)0.68 (0.63 to 0.73)
    subset of original cohort whose duration of transplant before failure was <12 mo (n = 1545)0.76 (0.65 to 0.90)
    subset of original cohort whose duration of transplant before failure was ≥12 mo (n = 9318)0.65 (0.60 to 0.71)
  • Results are given for the overall cohort and six sensitivity analyses examining the potential influence of inclusion or exclusion of specific patient subgroups. All models were adjusted for quartile of propensity score, age, gender, race, lack of medical insurance, coronary disease, previous myocardial infarction, previous cardiac arrest, congestive heart failure, cerebrovascular disease, diabetes, diagnosed hypertension, chronic obstructive pulmonary disease, cancer, inability to ambulate, inability to transfer, obesity, serum creatinine, serum albumin, hemoglobin, donor age, donor race, anoxia, donor cause of death, cold ischemia time, year of transplantation, and interim hospitalizations for any of the following: Complication of anemia, abdominal pain, urinary obstruction, sepsis, urinary tract infection, malnutrition, or complication of transplanted kidney.
