Characteristics and Outcomes of Kidney Transplant Recipients Requiring High-Acuity Care After Transplant Surgery: A 10-Year Single-Center Study

OBJECTIVE: To study the characteristics and outcomes of a cohort of kidney transplant recipients who required high-acuity care after transplant surgery. PATIENTS AND METHODS: All adult (aged ≥18 years) solitary kidney transplant recipients from January 1, 2007, through December 31, 2016, were screened and those who required high-acuity care within the same hospitalization were enrolled. Patient demographic and clinical data were collected from the departmental database and electronic DataMart. RESULTS: Of 1525 patients, 266 (17.4%) required high-acuity care after the kidney transplant operation: 166 (62.4%) directly from the operating room and 100 (37.6%) after an interval during the same hospitalization. Overall, 2 main indications were hypotension (n=87; 32.7%) and cardiac rhythm disturbances (n=83; 31.2%). Recipients in the direct admission group had higher medium body mass index (31.0 [interquartile range, 26.6-36.0] vs 28.0 [interquartile range, 24.3-32.4] kg/m(2); P<.001) and were more likely to have undergone a concomitant procedure with the transplant surgery. Overall, in-hospital mortality was 1.9% (n=5). CONCLUSION: In contemporary practice, patients with higher body mass index are more likely to require high-acuity care immediately after kidney transplant surgery. The most common reasons are hypotension and cardiac rhythm disorders. The overall intensive care unit mortality rate of these patients is low. However, these patients are at risk for graft loss and death in the long term compared with patients who do not require intensive care unit care after transplant surgery.
